Problems solved by technology

[0004] Among the above methods, the former two increase the complexity of processing, reduce the efficiency, and increase the processing cost; the latter is extremely difficult to remove manually due to the tightness between the part and the bushing due to thermal expansion after welding

Abstract

The invention relates to a tooling fixture for manufacturing an output bracket of an automobile transmission, the tooling fixture includes a base, a ring gear, a gear set, a cover plate, a rack set, a part positioning device, and a ring gear limiting device. The gear set is internally meshed, and the gear set and the rack set are meshed for transmission. A gear limit device is installed on the gear ring to prevent the gear rack from falling out of the tooling due to excessive rotation of the gear ring. A part positioning device is installed in the center of the top surface of the base to position the parts. The present invention utilizes the principle of rack and pinion meshing transmission, changes the traditional car steps, segmental welding, manual bushing and other methods, overcomes the shortcomings of traditional methods such as complexity, inefficiency, and high cost, and has a simple structure, durability, and realizes The entire process of press fitting and welding is automated, and the part positioning device on the base can ensure the positional relationship between the center of the part and the spindle of the machine tool, and the positioning accuracy is absolutely guaranteed.

Description

technical field [0001] The invention relates to a tooling fixture for manufacturing an output bracket of an automobile transmission. Background technique [0002] Such as figure 1 and figure 2 As shown, in the manufacturing process of the existing automobile six-speed automatic transmission output bracket assembly, after the housing 12 and the claw-shaped member 11 are press-fitted, laser welding is performed at the junction 13 of the housing 12 and the claw-shaped member 11 . [0003] In the traditional welding process of similar parts in the past, in order to achieve the distance H between the claw-shaped piece 11 and the housing 12 to meet the requirements of the set distance, some of them used to process steps at the claw feet of the claw-shaped piece 11 to be welded. ; or the surface and feet of the claw-shaped piece 11 are produced respectively by powder metallurgy, segmented welding, and the distance is controlled by the length of the feet; Bushings for spacing, t...
