Pneumatic type clamping tool for automobile frame welding device

Abstract

The invention provides a pneumatic type clamping tool for an automobile frame welding device. The clamping tool comprises a main body seat A, an adjusting bolt and a locking bolt; and the top end faceof the main body seat A is symmetrically provided with two sliding grooves, and the left side of the top end face of the main body seat A is fixedly connected with a pneumatic telescopic rod througha bolt. A buffering structure is improved, and a rubber pad is arranged between a main body plate B and a clamping plate, so that the damage of the clamping plate to a part during a rapid clamping process can be reduced through the buffering of the rubber pad; and a buffer rod structure is arranged, through the arrangement of the buffer rod structure, the clamping plate can push a support arm anda sliding seat to move after being stressed, a spring can be compressed to form a buffer when the sliding seat slides on a cylindrical rod, through the arrangement of the adjusting bolt, the buffer strength of the spring can be adjusted by rotating the adjusting bolt, and through the arrangement of the locking bolt, the problem that the buffering force is reduced due to looseness of the adjustingbolt in the using process can be avoided.

Description

technical field [0001] The invention belongs to the technical field of automobile processing tooling, and more specifically relates to a pneumatic clamping tooling for an automobile beam welding device. Background technique [0002] Tooling fixture is a kind of process equipment used to fix the workpiece during parts processing. The tooling fixture can ensure the machining accuracy and processing efficiency of the workpiece, which is conducive to improving labor productivity and reducing process costs. [0003] For example, the application number: CN201721112143.7, the invention discloses a pneumatic tooling fixture, including a base (1), on which a fixture positioning seat (2) is arranged, and the outer side of the base (1) passes through a support plate (3) A cylinder mount (4) is provided, a cylinder (5) is provided at the bottom of the cylinder mount (4), and one end of the cylinder (5) is provided with a plurality of pressure plates (7) through a fixture fixing plate (6...

AI Technical Summary

Problems solved by technology

[0005] One is that during the clamping process, especially when clamping pipe parts, the impact caused by quick clamping is easy to cause damage to the parts, and there is no corresponding buffer structure to relieve the impact pressure; secondly, the cost of use High, when the parts need to be clamped for a long time, the pneumatic telescopic rod of the existing device needs continuous air supply, which will easily lead to an increase in cost
