Description
Technical Field
[0001] The invention relates to the technical field of clamping devices, and in particular to an assembly tool for automobile parts. Background Art
[0002] Automobile parts assembly equipment is a kind of equipment used to assemble automobile parts in the automobile manufacturing process, such as differentials. The differential parts are fixed by fixing devices, and the assembly parts are grabbed to the fixing devices by grabbing devices to assemble the parts. However, the existing automobile parts assembly equipment has low working efficiency and cannot be applied to various types of parts assembly.
[0003] The prior art discloses a patent with announcement number CN209954170U, which includes: a base, a fixed clamping plate, and a limit plate. A positioning hole for supporting and clamping the lower end of the active helical gear assembly is provided in the middle position of the base near one end; the fixed clamping plate is installed on the upper surface of the base near the other end, and a through hole is provided on the upper part of the fixed clamping plate; the limit plate passes through the through hole and moves laterally in the through hole. The overall structure of the auxiliary tooling is simple, which is convenient for installation and disassembly, reducing the manufacturing cost and difficulty of use of the auxiliary tooling.
[0004] As the existing technologies including the above patents are used, their shortcomings are gradually exposed, mainly in the following aspects:
[0005] First, traditional assembly fixtures are usually designed for specific types of differentials. During the differential assembly process, the main task is to ensure the assembly accuracy between the inner shaft and the outer sleeve. When the production line needs to switch to a different type of differential, the existing fixtures are often unable to quickly assemble different types of inner shafts and outer sleeves, resulting in a time-consuming and labor-intensive process of adjusting the fixture to adapt to different types of differentials. Setup and adjustment usually require a lot of manual work, resulting in a significant increase in production preparation time and line change time.
[0006] Second, the existing fixtures can often only adapt to a single clamping angle during the assembly process. Due to the influence of the fixture on the clamping position of the jacket, when the clamping position of the jacket needs to be processed and assembled, the jacket needs to be disassembled and re-fixed, which causes changes in the clamping accuracy. It takes a lot of time to calibrate with the previous clamping accuracy, which reduces the assembly efficiency.
