Abstract

Disclosed is a wheel airtight rubber ring press-fitting device, consisting of a frame, first servo motors, ball screw pairs, first guide rails, a first cylinder and the like. The device may be used for automatic continuous production. The central axis of an airtight rubber ring coincides with the central axis of the outer rim of a wheel, so that the positioning precision is improved, and high-precision press-fitting is realized. Through cyclic switching of double manipulators, the press-fitting feeding time is nested, the press-fitting cycle is shortened, and the working efficiency is improved.

First claim

What is claimed is:

1. A wheel airtight rubber ring press-fitting device, comprising: a frame, first servo motors, ball screw pairs, first guide rails, a first cylinder, a left sliding plate, a gear rack, a right sliding plate, rough positioning wheels, lifting plates, two second cylinders, second guide rails, sliding blocks, four precision positioning wheels, airtight rubber rings, first guide posts, a pressure plate, a first lifting platform, four third cylinders, two fourth cylinders, second guide posts, a second servo motor, a second lifting platform, a rotating table, a first manipulator, a second manipulator, two fifth cylinders, third guide posts and a third lifting platform, wherein the wheel airtight rubber ring press-fitting device, further comprising a wheel positioning unit, a rubber ring placement and supply unit, and a rubber ring press-fitting unit;
the wheel positioning unit is as follows: one of the first servo motors is fixedly mounted on the left side of the frame, the output end of the first servo motor is connected with one of the ball screw pairs, the first servo motor controls the up-and-down movement of a lifting plate under the guidance of a guide rail, a second cylinder is fixed on the lifting plate, the output end of the second cylinder is connected with a sliding block to control the horizontal movement of the sliding block under the guidance of a second guide rail, and two of the four precision positioning wheels are mounted at the front end of the sliding block and used for precisely positioning an outer bead seat; the right side of the frame is arranged in the same manner as the left side, and the other two of the four precision positioning wheels are symmetrically distributed; after a wheel is roughly positioned, the rough positioning wheels are retracted and reset, and the second cylinders on the left and right sides are simultaneously started to drive the four precision positioning wheels to contact the outer bead seat of the wheel so as to realize precision positioning;
the rubber ring placement and supply unit is as follows: the output ends of the fourth cylinders are connected to the second lifting platform, and the fourth cylinders control the up-and-down movement of the second lifting platform under the guidance of the second guide posts; the second servo motor is fixed on the second lifting platform, and the output end of the second servo motor is connected to the rotating table; the first manipulator and the second manipulator are bilaterally symmetrically mounted on the rotating table; during working, the first manipulator on the left side is used for placing one of the airtight rubber rings, the second manipulator on the right side is used for loading another of the airtight rubber rings, and the left and right positions of the first manipulator and the second manipulator are configured to be cyclically switched through the second servo motor; the output ends of the fifth cylinders are connected to the third lifting platform, the fifth cylinders control the up-and-down movement of the third lifting platform under the guidance of the third guide posts, and the airtight rubber rings are vertically stacked on the third lifting platform; and in an initial state, the left first manipulator is loaded with one of the airtight rubber rings, and the right second manipulator is unloaded; after the wheel is precisely positioned, the fourth cylinders drive the second lifting platform to descend, so that the airtight rubber ring contacts the front side of the wheel; then, the first manipulator is opened to release the airtight rubber ring; next, the fourth cylinders drive the second lifting platform to descend again a certain distance to reserve a space for press-fitting; the fifth cylinders drive the third lifting platform to ascend a certain distance during press-fitting so that the airtight rubber ring stacked at the top rises to an appropriate height clamped by the second manipulator, and then the second manipulator clamps the top airtight rubber ring;
the rubber ring press-fitting unit is as follows: the third cylinders are mounted at the top of the frame, the third cylinders control the up-and-down movement of the first lifting platform under the guidance of the first guide posts, and the pressure plate is fixed on the first lifting platform; after the wheel is precisely positioned and the airtight rubber ring is placed on the front side of the wheel, the third cylinders are started, the pressure plate is driven to descend, and the airtight rubber ring is pressed into the outer rim of the wheel.
