A clamping and tightening device for an automobile tire assembly mechanical arm

Abstract

The invention provides a clamping and screwing device for an automobile tire assembling mechanical arm, and relates to the technical field of automobile assembling robots. The clamping and screwing device comprises a disk; a first gear is rotationally connected with the inner part of the disk through a ball; a first bevel gear is fixedly mounted at the front end of the first gear; a second bevel gear is engaged with the periphery of the first bevel gear; and a first threaded rod is fixedly mounted at one end, far from the center of the disk, of the second bevel gear. The clamping and screwingdevice can be adjusted to be applied to tires with different sizes at different mounting positions, so that the repeated replacement of the clamping and screwing deice is avoided, the clamping and screwing device is more convenient and quick, the practicability of the mechanical arm is improved, a tire is enabled to rotate per se, the energy consumption is reduced, the clamping and screwing deviceis simple in structure, and the manufacturing cost and difficulty of the mechanical arm are reduced.

Description

technical field [0001] The invention relates to the technical field of automobile assembly robots, in particular to a clamping and tightening device for an automobile tire assembly mechanical arm. Background technique [0002] With the continuous growth of the national economy, cars, as a common and convenient means of transportation, are becoming more and more popular, and the number of ownership is increasing every year, and cars are composed of various parts. It is necessary to assemble various parts in the car. With the advancement of technology, most of the assembly of cars can be completed by robots, and the tire assembly robot arm is one of them. [0003] For different types of cars, the size of the assembled tires is also different, and the positions of the bolts used to fix the tires are also different. Therefore, when assembling the tires of different types of cars, the traditional mechanical arm often It is necessary to replace the clamping and tightening device,...

AI Technical Summary

Problems solved by technology

[0003] For different types of cars, the size of the assembled tires is also different, and the positions of the bolts used to fix the tires are also different. Therefore, when assembling the tires of different types of cars, the traditional mechanical arm often It is necessary to replace the clamping and tightening device, which is cumbersome to operate and reduces the applicability. In order to adjust the angle of the tire during assembly, the traditional assembly device is often adjusted by rotating the entire mechanical arm, which increases the consumption of energy. And it is necessary to increase the rotating part of the mechanical arm, which increases the manufacturing cost and difficulty of the mechanical arm
