PU tube detection device used for high-end equipment manufacturing

Abstract

The present invention relates to a PU tube detection device used for high-end equipment manufacturing. According to the device, two clamping devices with adjustable radii and adjustable transverse spacing are used to reliably clamp a to-be-tested sample, two clamping plates at the end part and cone-shaped nails allow the clamping more reliable, and air-tightness test is performed via sealing and inflation at both ends. The upper end of the bracket is connected with an aperture detection device liftably. An outer diameter tube-clamping measuring device drives multiple radially-arranged lead screws via a rotating ring to feed, so that the outer diameter tube-clamping measuring device coordinates with support plates in an inner diameter tube-clamping measuring device to realize the effectivesupport and fixation on a to-be-tested end of the to-be-tested sample, and thus the measuring device between the inner diameter and the outer diameter can measure the aperture and thickness more accurately. In the measuring device, the principle that a light spring triggers an elastic piece to change the resistance value is exploited ingeniously, and the precise inner and outer diameter change isobtained. The device has the advantages of high detection accuracy, digital control, simple operation and ingenious structure, the manufacturing efficiency and the safety performance of the system areimproved, and thus the device is suitable for popularization.

Description

technical field

[0001] The invention belongs to the technical field of detection equipment, in particular to a detection device for PU pipes used in high-end equipment manufacturing. Background technique

[0002] PU pipe manufactured by high-end equipment has excellent high pressure resistance, vibration resistance, corrosion resistance, wear resistance, weather resistance, bending resistance, and lightness; The tube is flexible, durable, flexible, easy to use, has excellent temperature resistance and heat insulation and superior random bending performance, but in the manufacture of some high-end devices, PU tubes play the role of pneumatic or hydraulic transmission. The performance requirements of the tube are relatively high. Therefore, we need to perform performance testing on the PU tube used in the manufacture of high-end equipment, especially for the detection of the wall thickness and air tightness of the PU tube. transmission efficiency, and the wall thickness of th...
