A flexible welding fixture for auto parts

Abstract

The invention discloses a flexible welding fixture for automobile parts, which is characterized in that: the rear end of the pressing arm is connected with a special-shaped gear, the front end of the rotating shaft is a square structure, and the rear end is a circular structure, and the rear end of the rotating shaft is fixed on the machine base , the rectangular teeth on the special-shaped gear match the tooth grooves on the rack, the rack is set in the chute in the middle of the machine base, the side of the middle of the machine base is connected with the upper supporting seat, and the lower part of the upper supporting seat is fixed with an upper Flange, the bottom of the upper flange is fixed with a ring pipe and a support shaft, the ring pipe is inserted into the ring sleeve, the support shaft matches the lower casing, the lower flange and the upper flange have the same structure, the lower flange and the upper The flanges are connected by an adjusting screw, and an adjusting nut is provided on the adjusting screw, and the adjusting nut is located on the upper and lower parts of the upper flange, the lower flange is fixed on the upper part of the lower support seat, and the lower pressure block is fixed on the upper part of the fixed table, and the lower pressure block is fixed on the upper part of the fixed table. A pad iron is arranged between the block and the fixed platform, and the fixed platform is fixed on the upper supporting seat. The present invention has the advantage of being adjustable.

Description

technical field [0001] The invention belongs to the technical field of stamping dies, and in particular relates to a flexible welding fixture for auto parts. Background technique [0002] In the late 1950s, my country began to apply flexible combined fixture technology, and achieved good economic results. Since then, my country's flexible fixtures, that is, combination fixtures, have been using groove series combination fixtures to assemble them into fixtures that can adapt to various machine tools. Automobile flexible welding fixtures are produced based on welding fixtures and assembly fixtures. The characteristics of automotive flexible fixtures are: unified component specifications, multifunctional performance, simplified structure, modularization, and the ability to adjust the position of the fixture to suit different models. Automotive flexible fixtures provide convenience for the operation and work of the modern automobile manufacturing industry. Therefore, Automobil...

Problems solved by technology

[0003] The main problems of the existing flexible welding fixtures for auto parts are: 1) It cannot adapt to the changes of the auto parts. When the thickness of the parts changes, the fixture needs to be replaced; 2) The height of the fixture cannot be adjusted; 3) The angle of the fixture It cannot be adjusted, it can only be adjusted through the mounting hole on the fixture base, the adjustment space is limited, and it cannot meet the needs of modern auto parts production
