Problems solved by technology

[0004] The solution for fixing the pump body in the prior art is: use three cylinders to fix the pump body from three directions of the pump body respectively. However, the movements of the three cylinders are difficult to keep consistent, and the cylinder that moves first will move the pump body backwards. The cylinder is squeezed, causing the cylinder to deflect, which affects the alignment of the cylinder and the accuracy of detection

Embodiment Construction

[0017] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0018] Such as Figure 1 to Figure 3 As shown, a linkage compression type pump body air tightness testing fixture includes a base plate 1, a detection cylinder 11 is fixed on the rear side of the base plate 1, a horizontal baffle 1a is provided in the middle of the base plate 1, and the center of the baffle 1a A longitudinal round hole 1b is provided, and a pump body 10 is connected to the round hole 1b. The oil passage port of the pump body 10 passes through the round hole 1b and is located behind the baffle plate 1a. When in use, the oil passage of the pump body 10 The port is compressed by the detection cylinder 11, the front side of the base plate 1 is fixed with a compression cylinder 3 for directly compressing the pump body 10, and the mid...

Abstract

The invention relates to a linkage compression type pump body gas tightness detecting clamp. The linkage compression type pump body gas tightness detecting clamp comprises a baseplate, wherein a detecting air cylinder is fixed on the rear side of the baseplate; a horizontal baffle is arranged at the middle part of the baseplate; a longitudinal round hole is formed in the middle of the baffle; a pump body is communicated in the round hole; a compressing air cylinder is fixed on the front side of the baseplate; a left linkage compressing device and a right linkage compressing device are arranged in the middle of the baseplate and are symmetrically arranged on the left side and the right side of the axis of the compressing air cylinder. According to the invention, the linkage compression type is adopted, so that the number of the air cylinder is reduced, the production cost is reduced, and the convenience for detection is increased; the synchronism of devices on the compression of the pump body is improved, the pump body offset phenomenon caused due to the pump body compressed by a plurality of independent air cylinders respectively can be avoided, the pump body don't need to be adjusted and calibrated by the detecting air cylinder, and the detection efficiency and the production efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of fixtures, in particular to a linkage compression type pump body air tightness testing fixture. Background technique [0002] Everyday cars are equipped with pump bodies such as brake master cylinder, brake cylinder and clutch master cylinder. The brake master cylinder is also called the brake master oil (air) cylinder. Its main function is to push the brake The liquid (or gas) is transmitted to each brake cylinder to push the piston; the brake cylinder (brake cylinder) also has different appearances in different forms of braking systems, but they are the same in essence, they are all imported Brake fluid, and then push the piston in the slave cylinder to push the brake shoes or the brake pads to contact the brake drum or brake disc; the clutch master cylinder is the part connected to the clutch pedal and connected to the clutch booster through the oil pipe. It is to collect pedal stroke information to se...
