[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figure 1-4 , a copper-based electrical contact material detection fixture, comprising a base plate 1, on which two fixing mechanisms for fixing the copper-based electrical contact material are symmetrically arranged;

[0024] The fixing mechanism includes a guide rail 3 installed on the base plate 1, and two electric sliders 4 are installed on the guide rail 3. The tops of the two adjacent electric sliders 4 of the two fixing mechanisms are each installed with a mounting block 7. The opposite surfaces of the two mounting blocks 7 are provided with a slide groove 8. A sliding block 10 is slidably installed in the slide groove 8. A spring 9 is installed between the top of the sliding block 10 and the inner top wall of the slide groove 8. A rubber sleeve 11 is rotatably installed between the two sliding blocks 10, and a sticky pad 12 is bonded to the outer surface of the rubber sleeve 11.

[0025] As a technical optimization solution of the present invention, a rotating shaft 13 is rotatably installed between the two sliding blocks 10, and the rubber sleeve 11 is fixedly sleeved on the rotating shaft 13. The rotating shaft 13 can facilitate the installation of the rubber sleeve 11 and the sticky pad 12, and can provide an installation location for the rubber sleeve 11 and the sticky pad 12.

[0026] As a technical optimization solution of the present invention, the bottom end of the spring 9 is installed on the top of the sliding block 10, and the top end of the spring 9 is installed on the top wall of the sliding groove 8.

[0027] As a technical optimization solution of the present invention, limit blocks 5 are installed at both ends of the guide rail 3, and the limit blocks 5 are installed on the top of the base plate 1. The limit blocks 5 can provide a limiting effect on the electric slider 4 to avoid separation between the electric slider 4 and the guide rail 3.

[0028] As a technical optimization solution of the present invention, a workbench 2 is installed on the base plate 1, and the workbench 2 is located below the rubber sleeve 11. The workbench 2 can facilitate the placement of copper-based electrical contact materials, making it convenient to fix the copper-based electrical contact materials on the workbench 2 for testing the copper-based electrical contact materials in the later stage.

[0029] As a technical optimization solution of the present invention, a mounting hole 6 is provided on the base plate 1, and a countersunk groove is provided on the top of the mounting hole 6. The mounting hole 6 on the base plate 1 can facilitate the fixation of the base plate 1, thereby facilitating the installation of the device.

[0030] As a technical optimization solution of the present invention, bearing seats are installed on the opposite surfaces of the two sliding blocks 10, bearings are installed in the bearing seats, and the two ends of the rotating shaft 13 are respectively installed on the two bearing inner rings. The bearings can facilitate the rotational connection between the rotating shaft 13 and the sliding block 10.

[0031] When the present invention is used, when the copper-based electrical contact material needs to be fixed, the copper-based electrical contact material to be fixed is first placed on the workbench 2, and the two sets of electric slides 4 are started at the same time, and the two sets of electric slides 4 move towards each other on the two guide rails 3.

[0032] The two sets of electric sliders 4 move closer to each other on the two guide rails 3, which can drive the two rotating shafts 13 to move closer to each other until the rubber sleeve 11 on the outer wall of the rotating shaft 13 and the sticky pad 12 on the outer wall of the rubber sleeve 11 contact the copper-based electrical contact material, and the two rotating shafts 13 continue to move closer. The copper-based electrical contact material can generate a force on the sticky pad 12, the rubber sleeve 11 and the rotating shaft 13, and the force can be used to push the sticky pad 12, the rubber sleeve 11 and the rotating shaft 13 to move upward, thereby driving the sliding block 10 to move upward in the slide groove 8. Movement is used to compress the spring 9. At this time, the sticky pad 12, the rubber sleeve 11 and the rotating shaft 13 can move onto the copper-based electrical contact material, and the lower surface of the sticky pad 12 contacts the upper surface of the copper-based electrical contact material. The sliding block 10 pushes the sliding block 10 under the action of the reset force of the spring 9 to generate a downward force. The downward force can push the rotating shaft 13, the rubber sleeve 11 and the sticky pad 12 to generate a downward force on the copper-based electrical contact material, so that the copper-based electrical contact material can be fixed on the workbench 2 to complete the fixation of the copper-based electrical contact material.

[0033] In addition, two sticky pads 12 and two rubber sleeves 11 are used to fix the two ends of the copper-based electrical contact material. The spacing between the two sticky pads 12 and the two rubber sleeves 11 can be adjusted, so that copper-based electrical contact materials of different sizes can be fixed, thereby improving the comprehensiveness of fixing copper-based electrical contact materials of different sizes.

[0034] And when the sticky pad 12, the rubber sleeve 11 and the rotating shaft 13 are located on the copper-based electrical contact material, the two rotating shafts 13 continue to move closer. At this time, the rotating shaft 13 rolls on the copper-based electrical contact material to drive the rubber sleeve 11 and the sticky pad 12 to roll on the copper-based electrical contact material. The sticky pad 12 can be used to adhere to the dust and impurities on the surface of the copper-based electrical contact material by rolling on the copper-based electrical contact material, and then the dust and impurities on the surface of the copper-based electrical contact material can be adhered and removed to ensure the cleanliness of the copper-based electrical contact material before detection, thereby avoiding the presence of dust and impurities on the surface of the copper-based electrical contact material before detection, which affects the accuracy of subsequent detection.

[0035] 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.
