Embodiment 1

[0039] Embodiment one, combined with the attached Figure 1-18 , used for high-end equipment manufacturing PU tube detection device, including a bracket 1, characterized in that a set of clamping devices are installed on the bottom of the bracket 1, for clamping and fixing the PU tube sample to be tested, because the PU tube belongs to soft It is a high-quality tubular material, so it is necessary to clamp and fix the two ends of the PU tube when testing the airtightness and the thickness of the tube wall. Therefore, adding a clamping device is equivalent to erecting the two ends of the PU tube. The bracket 1 The upper vertical sliding fits a moving plate 2, and the moving plate 2 relies on a T-shaped slider for vertical sliding fit, so that the moving plate 2 can only move in the vertical direction. direction displacement, a lifting device for driving the moving board 2 is connected between the moving board 2 and the top of the support 1, and the lifting device drives the mov...

Embodiment 2

[0043] Embodiment two, on the basis of embodiment one, in conjunction with the attached Figure 1-18 , the outer diameter pinch measuring device includes a fixed cylinder 22 installed in the fixed ring 6, the fixed cylinder 22 is fixedly installed in the fixed ring 6, the external rotation of the fixed cylinder 22 is connected to a rotating ring 23, the fixed cylinder 22 There is an annular chute with a T-shaped cross-section on the outer wall, and the chute is slidably matched with a slider with a T-shaped cross-section connected in the rotating ring 23, so that the rotating ring 23 can only move along the circumference of the fixed cylinder 22. direction, the rotating ring 23 is externally connected with multiple sets of sleeves 24 that rotate radially through the fixed cylinder 22, and the sleeve 24 is externally fixed with a second gear 25, and multiple sets of second gears 25 meshes with the first ring gear 26 coaxially installed on the rotating ring 23, and the inner thr...

Embodiment 3

[0046] Embodiment three, on the basis of embodiment one, in conjunction with the attached Figure 1-18 , the inner diameter pinch measuring device includes a quill 8 fixedly installed on the left vertical plate 7, a rotary cylinder 41 is rotatably connected inside the quill 8, and a rotary cylinder 41 is rotatably connected with a Swivel 42, said swivel 42 is externally rotated and sleeved with a circular ring 43, an annular groove structure is formed on the rotating cylinder 41 in the axial direction, and the rotation of the swivel 42 is set in this groove structure, and the swivel 42 The outer ring 43 is flush with the outer diameter of the sleeve shaft 8, and both sides of the ring 43 are intermittently matched with the sleeve shaft 8. The coaxial rotation of the rotating drum 41 is sleeved with a ring fixedly installed on the vertical plate 7. Connecting rod 44, the connecting rod 44 is rotatably set in the drum 41, it is fixedly installed on the vertical plate 7 at the en...

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...
