Problems solved by technology

At present, the assembly is carried by hand or by rope and loaded into the shell. Due to the heavy weight of the assembly, the labor intensity of moving the assembly is high, the matching accuracy between the assembly and the shell is low, and the assembly efficiency is low.
At the same time, the parts will move due to manual or rope handling, which will lead to the failure of the assembly itself and the precision between the assembly and the shell to meet the design requirements, that is, the quality of the product cannot be guaranteed.

Abstract

The invention provides a hoisting clamp for speed changer assembly, belonging to the technical field of mechanical engineering, and aims to solve the problems of high labor intensity for moving a combined piece, relatively low precision for matching the combined piece and a shell and low assembly efficiency caused by large weight of a shaft system and shifting fork assembly combined piece in the conventional speed changer assembly. The hoisting clamp for speed changer assembly comprises a positioning board, wherein a plurality of shifting fork positioning pieces for positioning a shifting fork assembly are fixedly connected to a board surface of the positioning board; a plurality of shaft system positioning components for fixing a shaft system are arranged on the positioning board; and a hoisting ring is fixedly connected to the other board surface of the positioning board. The hoisting clamp for speed changer assembly and a hoisting tool are used for hoisting workpieces, so that a phenomenon of mutual displacement of accessories during transportation is avoided; and the hoisting clamp for speed changer assembly has the advantages of firm connection, stable force application and transportation, labor saving and the like. The process of assembling the combined piece and the shell can be adjusted immediately, so that the assembly quality of a product can be guaranteed effectively.

Description

technical field [0001] The invention belongs to the technical field of mechanical engineering, and relates to a clamp, in particular to a lifting clamp used for assembling a transmission. Background technique [0002] A transmission is a mechanism for changing speed and torque. It is widely used in machines such as machine tools, automobiles and tractors. The transmission includes housing, shafting and shift fork; because of the large number of parts in the transmission, the assembly process is extremely complicated. The assembly method generally adopted at present is to assemble relevant components into an assembly, and then put the above-mentioned assemblies into the housing one by one. For the convenience of handling, the weight of the above-mentioned assemblies is relatively small, which will increase the total number of assemblies, complicate the assembly process, and affect the assembly efficiency. [0003] Some types of transmissions require the shafting and shift ...
