Abstract

The present application discloses a wheel bolt pressing device, which includes a frame, a servo motor, a connecting shaft, a bottom plate, a mounting base, a cylinder, a support, a spring A, a pull pin, a limiting sleeve, a thrust bearing, a bracket, a bolt, a strong magnet, a bolt mounting rack, a large linear bearing, a guide shaft, a press-down cylinder, a cylinder flange, a balancing stand, a guard, rollers, a mounting shaft, a mounting rack, contacts, an elastic rubber band, a holder, pin rolls and the like. The device may meet the requirement of a wheel for pressing bolts on line in use, which has ideal effect, high efficiency, and high automation degree. In addition, the wheel bolt pressing device is safe and reliable in work, and is particularly suitable for batch production in production lines.

First claim

What is claimed is:

1. A wheel bolt pressing device, comprising a frame, a servo motor, a connecting shaft, a bottom plate, a mounting base, a cylinder, a support, a spring A, a pull pin, a limiting sleeve, a thrust bearing, a bracket, a bolt, a magnet, a bolt mounting rack, a large linear bearing, a guide shaft, a press-down cylinder, a cylinder flange, a balancing stand, a guard, rollers, a mounting shaft, a mounting rack, contacts, an elastic rubber band, a holder, pin rolls, a base, a copper sleeve, a radial bearing, a bearing end cover, a cylinder pull rod, a base plate, a second cylinder, a linear bearing A, a positioning pin, a spring B, a linear bearing B and a floating shaft, wherein the bottom plate and the servo motor are mounted on the frame, the mounting base and the support are mounted on the bottom plate, the cylinder and the linear bearing A are mounted on the support, the pull pin penetrates through the spring A and the linear bearing A and is connected with an output shaft of the cylinder, the thrust bearing and the radial bearing are mounted on the mounting base; the limiting sleeve is connected with the thrust bearing via the bracket, the front conical surface of the pull pins are configured to be matched with the lateral limiting hole of the limiting sleeve; the base plate is connected with an output shaft of the servo motor via the connecting shaft, the upper end face of the base plate is connected with the bracket, and the bearing end cover is fixed on the base plate and the bearing end cover is connected with the radial bearing; the servo motor is configured to drive the bracket to rotate a specified angle; the cylinder and the spring A is configured to control extension and contraction of the pull pin; when air is introduced into the cylinder, the front conical surface of the pull pin is configured to be matched with a lateral limiting hole of the limiting sleeve, and a wheel is configured to be fixed at a certain specific angle under the cooperation of the servo motor;
the linear bearing B is fixed on the bracket, the floating shaft is mounted on the linear bearing B via the positioning pin and the spring B; the base and the copper sleeve are mounted on the base plate; the cylinder pull rod penetrates through the copper sleeve, and has two ends connected with the output shaft of the cylinder and the guard respectively; the mounting rack is fixed on the cylinder pull rod, six rollers of the rollers are uniformly mounted on the mounting rack via six pin rolls of the pin rolls, six contacts of the contacts are uniformly mounted on the base via the holder and the pin rolls, the elastic rubber band is mounted on the holder, the rollers are in slope contact with the holder, the cylinder pull rod drives the rollers to move up and down under the coaction of hydraulic pressure and the elastic rubber band, while the rollers roll on the slope of the holder, the holder drives the contacts to rotate around the pin rolls, and the contacts have expansion and contraction functions, make wheels having different central hole diameters be positioned and clamped.

2. The wheel bolt pressing device of claim 1 , wherein the floating shaft penetrates through the spring B and the linear bearing B, the positioning pin is mounted at the upper end of the floating shaft, and the side wall of the positioning pin is of a positive conical surface structure; in placing process of the wheel, the positive conical surface structure of the positioning pin is inserted into a wheel bolt hole, and high-precision circumferential positioning of the wheel is guaranteed under the coaction of elasticity of the spring and self-weight of the wheel.
