A clamping device for airtight testing

Abstract

The invention relates to a clamping device for airtightness detection. The clamping device comprises a base, an axial clamping device, a radial clamping device and a positioning device, wherein slide grooves are formed in the front side and the back side of the base and are parallel with the width direction of the base, a bolt groove is formed in the middle part of the base, the axial clamping device is arranged in the slide grooves of the base, the radial clamping device is positioned at the right side of the axial clamping device, and is fixedly arranged on the base through a screw, and the positioning device is positioned at the left side of the axial clamping device, and is fixedly arranged on the base through a screw. The clamping device has the advantages that the operation is convenient, the clamping efficiency is high, the clamping is quick, the working efficiency of airtightness detection is greatly improved, the labor is saved, the production cost is reduced, a workpiece can be clamped by one operator, the convenience and rapidity are realized, and the operation safety of workers is improved.

Description

technical field [0001] The invention relates to the technical field of fixture processing, in particular to a clamping device for airtight testing. Background technique [0002] As we all know, the automobile brake wheel cylinder is installed in the automobile wheel disc, which is used for automobile braking and is an important device to ensure the safety of automobile braking. Common hydraulic brake wheel cylinders are usually used in general automobiles, generally including cylinder body , Piston, spring nozzle, etc. After the parts of the brake wheel cylinder are processed and assembled, they need to be inspected, such as service life inspection, reliability inspection, etc. Among them, the air tightness inspection is the most important and most critical step. The air of the brake wheel cylinder Whether the airtightness is good or bad will directly affect the braking effect of the braking system. If there is a mistake in the work of the airtightness detection link, the u...

Problems solved by technology

After the parts of the brake wheel cylinder are processed and assembled, they need to be inspected, such as service life inspection, reliability inspection, etc. Among them, the air tightness inspection is the most important and most critical step. The air of the brake wheel cylinder Whether the airtightness is good or bad will directly affect the braking effect of the braking system. If there is a mistake in the work of the airtightness detection link, the unqualified brake wheel cylinder will be regarded as a qualified product and sold. If the products flow into the market, it will lead to serious consequences, and the unqualified detection device may mistakenly discard the qualified products, resulting in a waste of resources. The clamping device of the brake wheel cylinder is an important part of the air tightness detection device. Parts play a pivotal role in the process of testing the air tightness of the brake wheel cylinder. The existing clamping technology has low work efficiency, inconvenient clamping and high cost, so there is an urgent need for a high-efficiency, convenient clamping The clamping device for testing the air tightness of the brake wheel cylinder
