Description

Technical Field

[0001] This utility model relates to the field of cutting tool testing technology, and more specifically, to a testing and classification device for cemented carbide cutting tools. Background Technology

[0002] As a common tool in daily life, the quality and safety of knives are of paramount importance. Visual inspection of knives is the first step in ensuring their quality and safety. It not only affects the aesthetics of the product but also directly relates to the performance and safety of the knife. Visual inspection can promptly detect defects, cracks, and other problems on the surface of the knife, thereby preventing accidents during use.

[0003] Currently, when inspecting cutting tools, the surface defects are mostly screened manually using visual inspection. During the long inspection and screening process, the inspectors are prone to visual fatigue, which affects the inspection efficiency and is prone to inspection errors, thus leading to defects in the appearance of the cutting tools.

[0004] Based on this, a detection and classification device for cemented carbide cutting tools is proposed. Summary of the Invention

[0005] The main objective of this invention is to provide a testing and classification device for cemented carbide cutting tools to overcome the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides a testing and classification device for cemented carbide cutting tools, including a testing box. A miniature dust pump is fixedly installed at the front center of the outer surface of the testing box, and miniature exhaust pumps are fixedly installed on both sides of the rear center of the outer surface of the testing box. A first testing rod in the shape of an inverted "L" is vertically arranged at the center of the inner bottom surface of the testing box. The vertical end of the first testing rod extends outward through the testing box. A second testing rod is movably installed at the vertical end of the first testing rod. An assembly frame is inserted and fixedly installed on the side of the outer surface of the other end of the first testing rod and the second testing rod that is close to each other.

[0028] Please see Figures 1-7As shown, a testing and sorting device for cemented carbide cutting tools includes a testing box 1. A guide groove 102 is laterally opened in the middle of the inner bottom surface of the testing box 1. A bidirectional screw 101 is movably installed on the inner surface of the testing box 1 through the guide groove 102. Adjustment blocks 103 are spirally and movably sleeved at both ends of the outer surface of the bidirectional screw 101. A locking clamp 104 is fixedly inserted and installed in the middle of the upper surface of the adjustment block 103.

[0029] The outer surface of the test box 1 has two openings on both sides of the middle of the rear end of the test box 1, and two openings on both sides of the outer surface of the test box 1, and two connecting pipes 107 are fixedly installed between the first air vent 105 and the micro exhaust pump 3 and between the second air vent 106 and the micro vacuum pump 2.

[0030] A miniature dust pump 2 is fixedly installed at the front center of the outer surface of the test box 1. A dust collection bag 201 is fixedly installed at the air outlet of the miniature dust pump 2. Miniature exhaust pumps 3 are fixedly installed on both sides of the center of the rear end of the outer surface of the test box 1. A first test rod 4 in the shape of an inverted "L" is vertically arranged in the center of the inner bottom surface of the test box 1. The vertical end of the first test rod 4 extends outward through the test box 1. A second test rod 401 is movably installed at the vertical end of the first test rod 4. A sealing cover 402 is movably fitted on the outer surface of the second test rod 401. An assembly frame 5 is inserted and fixedly installed on the side of the outer surface of the other end of the first test rod 4 and the second test rod 401 that is close to each other.

[0031] Several compression springs 501 are uniformly fixedly installed on the inner bottom surface of the assembly frame 5. An adjustment plate 502 is fixedly installed on the other end of the compression springs 501. An inverted "T" shaped fixing frame 6 is fixedly installed on the upper surface of the adjustment plate 502. Several protruding docking pins 503 are fixedly provided on both sides of the middle part of the upper surface of the adjustment plate 502. The other end of the docking pins 503 extends through the fixing frame 6 and into the interior. A powder roller 601 is fixedly inserted and installed on the upper surface of the fixing frame 6.

[0032] In use, the tool to be tested can first be held in the center between the locking plates 104. Then, by turning the bidirectional screw 101 clockwise, the adjusting block 103 can be controlled to close laterally along the guide groove 102, thereby driving the locking plates 104 to squeeze and clamp the two ends of the tool to fix it. Then, the sealing cover 402 can be covered on the test box 1 and pressed to maintain stability during the test. By pulling the first test rod 4 and the second test rod 401 back and forth, the powder roller 601 at its end will apply talcum powder to the surface of the tool during the pulling process. At the same time, as the powder roller 601 is consumed, the compression spring 501 will gradually unfold and push the adjusting plate 502 to drive the fixing frame 6 to slide towards the tool, thereby ensuring that the powder roller 601 is always in contact with the tool.

[0033] After talcum powder is applied to the surface of the knife, the micro exhaust pump 3 can be started to compress air and introduce it to the first air outlet 105 through the connecting pipe 107. The talcum powder on the surface of the knife is blown away through the first air outlet 105, thereby reducing the talcum powder content on the surface of the knife. At the same time, the micro vacuum pump 2 can be started simultaneously to suck up the talcum powder blown into the inspection box 1 through the connecting pipe 107 and the second air outlet 106 and store it in the dust collection bag 201. After the suction is completed, the knife can be taken out. If there are defects in the appearance of the knife, talcum powder will accumulate at the defective area, which can highlight the cracks on the appearance of the knife. The inspector can then complete the inspection and classification of the knife appearance into qualified products and defective products.

[0034] The above are merely embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
