Description

Technical Field

[0001] The utility model relates to the technical field of connecting wire detection, in particular to a device for detecting the wear resistance of connecting wires. Background Art

[0002] The wear resistance testing device for connecting wires is an important device for evaluating the durability of connecting wires in friction and wear environments.

[0003] Reference may be made to an existing document for detecting the wear resistance of a connecting wire (CN216525121U). In the existing document, a servo motor A, a turntable, a fixed plate, a servo motor B, a winding roller and an arc-shaped buckle are set, and the tightening and adjustment can be performed according to the length of the connecting wire. At the same time, the connecting wire can be rotated, so that any part of the connecting wire can be polished to achieve a better polishing effect.

[0004] In the reference, the end of the connecting wire is fixed to the winding roller by an arc-shaped buckle, and the surface of the connecting wire is polished by a laterally moving arc-shaped polishing block. This design can only detect a single connecting wire at a time, and the efficiency is low for the inspection of large quantities of finished connecting wires in the factory. At the same time, when the arc-shaped polishing block is close to the connecting wire, an automated telescopic equipment is generally used. The reference uses an electric telescopic rod. The electric telescopic rod drives the arc-shaped polishing block to move downward, which will generate a certain amount of pressure on the connecting wire. The specific pressure generated is difficult to know, and thus it is difficult to know the specific pressure required to cause wear of the connecting wire. Utility Model Content

The present invention clamps and fixes one end of a connecting wire by bringing two clamping plates together, then drives the connecting wire to move by the operation of a lateral moving assembly, and applies a certain pressure to the connecting wire through a grinding plate. The clamping plate can simultaneously fix multiple connecting wires and perform wear resistance testing simultaneously, thereby improving testing efficiency. At the same time, a pressure sensor is built into the grinding plate, which can more specifically display the pressure applied to the connecting wire, facilitating a more accurate understanding of the pressure that the connecting wire can withstand.

[0026] Reference Figure 1-4 A device for detecting wear resistance of a connecting wire comprises: a lower slide plate 2, an upper slide plate 3 and a positioning assembly. A lateral movement assembly is provided inside the lower slide plate 2 and the upper slide plate 3. An electric cylinder 11 is installed above the lateral movement assembly. A clamping plate 12 is connected above the electric cylinder 11. The operation of the lateral movement assembly drives the clamping plate 12 to move laterally, and the operation of the two electric cylinders 11 drives the two clamping plates 12 to clamp and fix one end of the connecting wire. The positioning assembly can drive the two grinding plates 21 to move in the opposite direction. The two grinding plates 21 apply a certain pressure to the connecting wire. When the connecting wire moves, friction can be applied to the surface of the connecting wire through the two grinding plates 21.

[0027] For details, please refer to Figure 2 The lower slide 2 and the upper slide 3 are both box-type designs. The driving source of the lateral movement component is a servo motor 7 which is fixed to one end of the lower slide 2 and the upper slide 3. The output end of the servo motor 7 is connected to a one-way screw 8, which can rotate on the inner side of the lower slide 2 and the upper slide 3. The threaded slider 10 is threadedly connected to the outside of the one-way screw 8 and can slide on the inner side of the lower slide 2 and the upper slide 3.

[0028] In this embodiment, the one-way screw 8 is driven to rotate by the operation of the servo motor 7, so that the threaded slider 10 connected to the external thread of the one-way screw 8 moves linearly on the inner side of the lower slide 2 and the upper slide 3.

[0029] Furthermore, the openings of the lower slide 2 and the upper slide 3 are fixedly connected to a closing plate 14, and a sliding groove 15 is provided on the surface of the closing plate 14. The width of the sliding groove 15 can just pass through the electric cylinder 11. The electric cylinder 11 is fixed on the surface of the threaded slider 10, so that the electric cylinder 11 slides in the sliding groove 15 during the linear displacement of the threaded slider 10.

[0030] Furthermore, two guide rods 9 are fixed on the inner sides of the lower slide 2 and the upper slide 3. The two guide rods 9 pass through the threaded slider 10, so that the threaded slider 10 slides outside the two guide rods 9 when moving in a straight line.

[0031] For details, please refer to Figure 2 The surface of the clamping plate 12 is provided with a plurality of arc-shaped clamping grooves 13 , and the upper and lower clamping plates 12 are symmetrically arranged so that multiple connecting wires can be fixed between the two clamping plates 12 at the same time.

[0032] For details, please refer to Figure 3 The positioning components are mainly composed of two L-shaped positioning rails 1 5 and 2 6. A servo motor 2 16 is installed above the positioning rail 1 5. The servo motor 2 16 drives the bidirectional screw 17 fixed at the output end to rotate, thereby causing the two threaded sliders 2 18 connected by external threads to move in opposite directions outside the bidirectional screw 17.

[0033] In this embodiment, a guide rod 2 19 is fixed on the inner side of the positioning rail 2 6, and two guide blocks 20 are slidably connected to the outside of the guide rod 2 19. The grinding plates 21 are fixed between the threaded slider 2 18 and the guide blocks 20. When the two threaded sliders 2 18 move in opposite directions, they drive the two grinding plates 21 to move in opposite directions, causing the two guide blocks 20 to slide outside the guide rod 2 19.

[0034] Further, such as Figure 4 As shown, the two grinding plates 21 adopt a symmetrical design. The grinding plates 21 have built-in pressure sensors 22. The surface of the pressure sensor 22 is a grinding surface 23. When the connecting line moves, friction is applied to the connecting line through the two grinding surfaces 23. At the same time, when the two grinding plates 21 move in opposite directions, pressure is applied to the connecting line. The pressure is detected in real time by the pressure sensor 22, and the detection signal is transmitted to the pressure display panel 24 on one side of the grinding plate 21. The pressure display panel 24 can display the pressure in a specific numerical value, and the detection personnel can then know the specific pressure required to cause wear of the connecting line.

[0035] Working principle: When using the utility model, the operation of the electric cylinder 11 causes the two clamping plates 12 to move toward the middle to clamp and fix one end of the connecting wire, and a plurality of arc-shaped clamping grooves 13 are provided on the surface of the clamping plate 12, so that multiple connecting wires can be fixed in the arc-shaped clamping grooves 13 at the same time, and then the connecting wire is driven to move by the operation of the lateral moving component, and a certain pressure is applied to the connecting wire through the polishing plate 21. When the connecting wire moves, friction can be applied to the surface of the connecting wire through the two polishing plates 21, and the wear resistance of multiple connecting wires can be tested at the same time to improve the detection efficiency. A pressure sensor 22 is built into the polishing plate 21, and the two polishing plates 21 are close to the connecting wire and apply a certain pressure to the connecting wire. The pressure generated will be detected in real time by the pressure sensor 22, and the detection signal is sent to the pressure display panel 24 for numerical display, which can make the pressure caused to the connecting wire more specific, and thus know the specific pressure required to cause wear of the connecting wire.

[0036] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
