Description

Technical Field

[0001] This utility model belongs to the field of equipment technology, specifically relating to an X-RAY non-destructive testing device for copper pipe welds. Background Technology

[0002] In air conditioning systems, copper pipes are responsible for transporting refrigerant from the compressor to the condenser, expansion valve, and evaporator to complete the refrigeration cycle. Air conditioning copper pipes are generally made of copper (also known as red copper), which has excellent thermal conductivity, corrosion resistance, and pressure resistance. They are a crucial component of air conditioning systems, carrying the circulating flow of refrigerant and playing a key role in ensuring the cooling effect of the air conditioner.

[0003] During the manufacturing process of air conditioning refrigeration copper pipes, defect detection at the weld positions is crucial for ensuring the normal operation of the refrigeration system and avoiding potential leakage risks. Currently, defect detection of refrigeration copper pipes is mainly achieved through visual inspection, using the naked eye or visual inspection systems to observe the weld surface for defects such as bubbles, cracks, and inclusions. This inspection method is simple and easy to implement, but it can only perform a static inspection of the copper pipe weld position and cannot detect defects in the connection strength of the copper pipe weld, thus limiting its effectiveness.

[0004] Patent application number 202411868001.8 discloses a welding defect detection device for air conditioning refrigeration copper pipes, including a base. The base is characterized by symmetrically arranged positioning components on both sides of its upper end. Each positioning component includes a shell with a central through hole. A copper pipe to be tested is horizontally inserted between the central through holes of the shell. A fixed crossbeam is fixedly arranged between the top ends of the shell. Fixed ring frames are fixedly arranged at both ends of the bottom of the fixed crossbeam. Movable ring frames are rotatably installed inside each fixed ring frame. Two movable ring frames are fixedly connected by mounting plates. There are four sets of mounting plates arranged in a cross shape. A pressure component is arranged on the top mounting plate, and a detection component is arranged on the bottom mounting plate. A camera and a laser detector are fixedly arranged on the left and right mounting plates, respectively. The weld seam of the copper pipe to be tested is located between the pressure component, the detection component, and the camera. Between the laser detector and the pressure assembly, the pressure component includes a bidirectional screw, both ends of which are rotatably mounted in rotating seats on the mounting plate. The bidirectional screw is driven by a rotating motor. Sliding seats are threaded through the threaded sections at both ends of the bidirectional screw and are slidably mounted in grooves on the mounting plate. The bottom of the sliding seat is rotatably engaged with one end of a connecting rod, and the other end of the connecting rod is rotatably engaged with the side wall of the slide cylinder. A fixed shaft is slidably mounted through the slide cylinder along the axial direction. The top end of the fixed shaft is fixedly connected to the mounting plate, and a buffer spring is provided between the bottom end of the fixed shaft and the slide cylinder. A punch head is fixedly mounted at the bottom of the slide cylinder, and the punch head is aligned with the weld joint of the copper tube to be tested. The laser detector, in conjunction with a camera, performs circumferential static detection of the weld position of the copper tube to be tested, and the detection assembly, in conjunction with the pressure assembly, performs circumferential dynamic detection of the weld position of the copper tube to be tested.

[0005] This air conditioning refrigeration copper pipe welding defect detection device is designed to stabilize the copper pipe for detection, but it still cannot fully detect the welding effect inside the copper pipe weld. Utility Model Content
