One-piece clamp for automotive welding

Abstract

The invention relates to an integrated clamp used for automobile welding. The clamp comprises an air cylinder, a shell, a clamping arm rotating piece, a connecting rod, a clamping in-place induction block, a clamping in-place proximity switch, a driving rod, an opening in-place proximity switch, a driving bevel gear and a driven bevel gear. A proximity switch support is arranged to be connected with the shell. A connecting rod mechanism is composed of the clamping arm rotating piece, the connecting rod and the driving rod. A dust cover is loosened and rotated so that an adjusting hole in the shell can be exposed. The driving bevel gear is inserted into the adjusting hole in the shell, the driving bevel gear is adjusted to rotate, and the rotation direction is changed from the horizontal direction into the vertical direction through the cooperation of the driving bevel gear and the driven bevel gear. The driven bevel gear drives a piston rod of the air cylinder to rotate, the mounting distance between the driving rod and the piston rod of the air cylinder is changed, and accordingly the opening angle of the clamping arm rotating piece is adjusted. The integrated clamp for automobile welding is simple in structure and reasonable in design, quite high clamping force is generated through relatively low working air pressure, automatic locking can be achieved in the clamping position, using is safe and reliable, and the application effects are quite remarkable.

Description

technical field [0001] The invention relates to an automobile manufacturing equipment, in particular to an integrated clamp used for automobile welding. Background technique [0002] At present, the production competition in the automobile industry is very fierce. There are generally two existing clamping methods for automobile welding: one is to use eccentric clamping cylinders, but due to the limited clamping output torque of eccentric clamping cylinders, self-locking cannot be realized. The second is to purchase an integrated clamping cylinder. The common integrated clamping cylinder on the market often has the following problems: adjustment is not convenient, and additional adjustment bolts need to be purchased when the opening angle of the cylinder needs to be adjusted, and the application effect is not good; at the same time, foreign orders Cumbersome and very expensive. [0003] Therefore, it is one of the problems that technicians in this field should start to solve...
