Abstract

The invention relates to a tooling clamp for manufacturing an output bracket of an automobile speed changer, comprising a base, a gear ring, a gear group, a cover plate, a rack group, a part positioning device and a gear ring limiting device, wherein the gear ring is internally meshed with the gear group which is in meshed transmission with the rack group; the gear ring is provided with the gear ring limiting device so as to prevent the gear ring from rotating excessively and further causing racks to separate out of a tooling; and the center of the top surface of the base is provided with a part positioning device for positioning parts. In the invention, by utilizing the principle that the gear and the racks are in meshed transmission, the traditional methods of turning, sequence welding, and manual placement of bushes and the like are changed, the defects that the traditional mode is complex, is low in efficiency and high in cost are overcome, the structure is simple and durable, automation of the whole process of press-fitting and welding is realized, the part positioning device on the base can ensure the position relation of the centers of the parts and a main shaft of a machine tool, and the positioning accuracy can be guaranteed absolutely.

Description

technical field [0001] The invention relates to a tooling fixture for manufacturing an output bracket of an automobile transmission. Background technique [0002] like 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, to b...
