Automatic centering mechanism for pneumatic plug gauge detection

Abstract

The invention discloses an automatic centering mechanism for pneumatic plug gauge detection, which comprises a mounting seat, a vertical through hole is formed in the mounting seat, a concave step is formed on the inner wall of the upper part of the through hole, a linear bearing is arranged at the concave step, the outer ring of the linear bearing is fixedly connected with a check ring, and the bottom surface of the check ring is in contact with the step surface of the concave step; a guide rod is vertically inserted into an inner ring of the linear bearing in a penetrating mode, a ball head is arranged in the middle section of the guide rod and matched with the inwards-sunken portion of the middle of a first fixing base, the first fixing base is connected with the installation base, and a spring sleeves the transition position of the guide rod and the ball head; and the gasket is contacted with the bottom surface of the linear bearing and has the same diameter as the linear bearing. In the valve sleeve detection process, automatic centering can be achieved, meanwhile, the inner diameter of the valve sleeve is detected, the consistency of products is kept, and the product quality is improved.

Description

technical field [0001] The invention belongs to the technical field of manufacturing valve sleeve detection devices, and in particular relates to an automatic centering mechanism for pneumatic plug gauge detection. Background technique [0002] The valve sleeve is an important part of the hydraulic valve. The valve sleeve is the only accessory that can be worn. The valve is pressed by compressed air on the valve sleeve. The valve casing forms a part of the operator, so that expensive piston operators, operating membranes, or electric motors can be avoided. The air pressure is between the valve casing and the valve sleeve to operate the opening and closing of the valve and throttling. . [0003] The inner hole of the valve sleeve mainly needs to be formed by machining, and the inner hole of the valve sleeve needs to be fully inspected. In the prior art, most of the valve sleeves are inspected by humans. This detection method is extremely low in efficiency and high in cost, a...

Problems solved by technology

[0003] The inner hole of the valve sleeve mainly needs to be formed by machining, and the inner hole of the valve sleeve needs to be fully inspected. In the prior art, most of the valve sleeves are inspected by humans. This detection method is extremely low in efficiency and high in cost, and the quality of the detected valve sleeve Uneven, the overall quality cannot be guaranteed, a small part of the valve sleeve is tested by the device, but it is easy to scratch the inner hole of the valve sleeve when testing the inner hole of the valve sleeve, and there is a problem that the valve sleeve and the inner diameter detection component are not easy to align
