Abstract

A wheel corner polishing device includes a station switching system, a valve hole polishing system, a bolt hole polishing system and a rim and cap section synchronous polishing system. The wheel corner polishing device can automatically polish four positions including bolt hole corners, a valve hole corner, outer rim corners and cap section corners of a wheel via upper and lower stations and coordination of the systems.

First claim

The invention claimed is:

1. A wheel corner polishing device, being composed of a rack, a first jacking cylinder, four first guide posts, a first lifting table, a first guide rail, a first adjusting cylinder, a first sliding table, a first polishing motor, an outer rim polishing head, a second jacking cylinder, four second guide posts, a second lifting table, a second guide rail, a second adjusting cylinder, a second sliding table, a second polishing motor, a cap section polishing head, a station switching motor, a coupling, a bearing seat, a bearing, a station switching table, four positioning guide rails, a fifth sliding table, a sixth sliding table, a gear rack, a clamping cylinder, two drive motors, clamping wheels, a polishing roller bed, a wheel feeding roller bed, a wheel discharge roller bed, a pitch adjusting guide rail, a pitch adjusting sliding table, a pitch adjusting cylinder, a third guide rail, a third adjusting cylinder, a third sliding table, a connecting rod, a turning plate, a feeding guide rail, a feeding sliding table, a feeding cylinder, a third polishing motor, a valve hole polishing head, a vision sensor, a servo motor, a shaft, a rotating table, an electric cylinder, a support frame, third guide posts, a feeding platform, a fourth guide rail, a fourth sliding table, an fourth adjusting cylinder, a fourth polishing motor and a bolt hole polishing head, wherein
the station switching motor is fixed on the rack, an output end of the station switching motor being connected with the station switching table via the coupling, and the polishing roller bed and the four positioning guide rails being mounted on an upper surface of the station switching table; the fifth sliding table and the sixth sliding table being symmetrically mounted on the four positioning guide rails, and being connected via the gear rack; the clamping cylinder being fixed on the station switching table, and an output end of the clamping cylinder being connected with the fifth sliding table; two drive motors being respectively mounted on the fifth sliding table and the sixth sliding table, and the clamping wheels being mounted at output ends of the two drive motors; in an upper station, a wheel is positioned and clamped on the upper surface of the station switching table, and then corners of bolt holes and a valve hole being polished; in a lower station, the wheel being positioned and clamped on a lower surface of the station switching table, and then corners of an outer rim and cap sections being polished; corner polishing of four positions being completed via switching and coordination of the upper station and the lower station;
the pitch adjusting cylinder and the pitch adjusting guide rail being fixed on the rack, the pitch adjusting sliding table being mounted on the pitch adjusting guide rail, and an output end of the pitch adjusting cylinder being connected with the pitch adjusting sliding table to control horizontal movement of the pitch adjusting sliding table; the third adjusting cylinder and the third guide rail being fixed on the pitch adjusting sliding table, the third sliding table being mounted on the third guide rail, and an output end of the third adjusting cylinder being connected with the third sliding table to control horizontal movement of the third sliding table; the turning plate being articulated with the pitch adjusting sliding table, one end of the connecting rod being articulated with the third sliding table, a second end of the connecting rod being articulated with the turning plate, and when the third adjusting cylinder drives the third sliding table to move horizontally, a turning angle of the turning plate being adjusted; the feeding cylinder and the feeding guide rail being fixedly mounted on the turning plate, the feeding sliding table being mounted on the feeding guide rail, an output end of the feeding cylinder being connected with the feeding sliding table, the third polishing motor being fixed on the feeding sliding table, and the valve hole polishing head being mounted at an output end of the third polishing motor; the vision sensor being mounted at a bottom of the turning plate;
the servo motor being fixedly mounted at a top of the rack, and an output end of the servo motor being connected with the rotating table via the shaft to control rotation of the rotating table; the support frame being fixed on the rotating table, the electric cylinder being fixed on the support frame, and an output end of the electric cylinder being connected with the feeding platform to control up-down motion of the feeding platform under a guiding effect of the third guide posts; the fourth guide rail and the fourth adjusting cylinder being fixed on the feeding platform, the fourth sliding table being mounted on the fourth guide rail, and an output end of the fourth adjusting cylinder being connected with the fourth sliding table to control horizontal motion thereof; the fourth polishing motor being mounted on the fourth sliding table, and the bolt hole polishing head being mounted at an output end of the fourth polishing motor; after the valve hole of the wheel is recognized by the vision sensor, the wheel stopping rotating, a first polished bolt hole being determined according to an included angle between the valve hole and a first bolt hole of the bolt holes corresponding to the first polished bolt hole, at the moment, the servo motor being started to drive the rotating table to rotate, the bolt hole polishing head is thus driven to rotate around a center of the wheel, the bolt hole polishing head rotating to a position above the first bolt hole that needs to be polished, and then the electric cylinder being started to drive the rotating bolt hole polishing head to be fed down to polish a corner of the first bolt hole; after the corner of the first bolt hole is polished, the electric cylinder driving the bolt hole polishing head to move up and reset, then the servo motor continuously driving the bolt hole polishing head to rotate around the center of the wheel, the bolt hole polishing head rotating to a position above a second bolt hole of the bolt holes according to an included angle between the bolt holes, the polishing beginning, all bolt holes being polished in sequence;
the first jacking cylinder being fixed on a cross beam at a bottom of the rack, and an output end of the first jacking cylinder being connected with the first lifting table to control ascending and descending of the first lifting table under a guiding effect of the four first guide posts; the first adjusting cylinder and the first guide rail being fixed on the first lifting table, the first sliding table being mounted on the first guide rail, an output end of the first adjusting cylinder being connected with the first sliding table to control horizontal motion thereof, the first polishing motor being mounted on the first sliding table, the outer rim polishing head being mounted at an output end of the first polishing motor, and feeding of the outer rim polishing head being controlled via the first jacking cylinder; the second jacking cylinder being fixed on the cross beam at the bottom of the rack, and an output end of the second jacking cylinder being connected with the second lifting table to control ascending and descending of the second lifting table under a guiding effect of the four second guide posts; the second adjusting cylinder and the second guide rail being fixed on the second lifting table, the second sliding table being mounted on the second guide rail, an output end of the second adjusting cylinder being connected with the second sliding table to control horizontal motion thereof, the second polishing motor being mounted on the second sliding table, the cap section polishing head being mounted at an output end of the second polishing motor, and feeding of the cap section polishing head being controlled via the second jacking cylinder; afte
