Detecting expander for automobile punching part

Abstract

Disclosed is a detecting expander for an automobile punching part. The detecting expander for the automobile punching part comprises a connecting arm (9) and a hydraulic cylinder (1), one end of the hydraulic cylinder (1) is connected with the connecting arm (9), the other side of the upper end of a tong jaw (10) is connected with a plunger (6) through a connecting block (12), a check ring (8) is fixed on the tong jaw (10), a sheath (11) is located at the front end of the tong jaw (10), the check ring (8) is located between the sheath (11) and a tong arm (7), and a front guard board (3) is located between a limiting block (2) and the tong jaw (10). By means of the detecting expander for the automobile punching part, serial problems of low producing efficiency, tendency to mechanical deformation and fracture and the like due to manual operation without special tools can be solved; time and effort can be saved during operation of separating welded parts; the structure is simple, the operation is easy, the producing efficiency is high, and risks of mechanical deformation and fracture and personnel security risks due to manual operation can be avoided.

Description

technical field [0001] The invention relates to a detection dilator, which belongs to the field of mechanical tools. More specifically, it is a test expander for automobile stamping parts. Background technique [0002] In the manufacture and production of auto parts, for the purpose of inspection and disassembly, it is often necessary to separate two mechanical parts that have been connected firmly. The existing method of separating the mechanical parts generally adopted is: manual tools such as hammers are chiseled open. In the specific implementation of the operation, the use of manual operation not only has limited force, is time-consuming and labor-intensive, but also has certain potential safety hazards, and it is easy to cause mechanical deformation and fracture. Therefore, there is an urgent need for a new detection and expansion tool with simple operation, small size, portability, low labor intensity and high efficiency. Contents of the invention [0003] The ob...
