Description

Technical Field

[0001] This utility model belongs to the field of grinding wheel testing technology, and in particular relates to a grinding wheel crack resistance testing device. Background Technology

[0002] Grinding wheels are abrasive tools used for grinding and cutting various materials. They are made of materials such as resin, ceramic, rubber, and bronze. Resin grinding wheels are highly efficient at grinding materials such as carbon steel, but abrasive particles may fall off in difficult-to-machine materials.

[0003] Traditional testing devices can only test the two sides or the center of the grinding wheel separately. This testing method is more troublesome to use because it requires two separate operations, which will increase the workload to some extent. Utility Model Content

[0004] The purpose of this invention is to provide a grinding wheel crack resistance testing device, which has the advantage of simultaneously testing the side and center positions of the grinding wheel, thereby solving the aforementioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A grinding wheel crack resistance testing device includes a side testing component and a center testing component. The center testing component is disposed at one end of the surface of the side testing component. The side testing component and the center testing component are detachably connected to a grinding wheel body. A center hole is opened in the middle of the surface of the grinding wheel body. The side testing component is used to test the two sides of the grinding wheel body, and the center testing component is used to test the center position of the grinding wheel body.

[0006] Preferably, the side test assembly includes a cylinder, a connecting plate, a clamping plate, and a fixing block. The connecting plate is fixedly connected to one end of the cylinder surface, and both ends of the connecting plate are fixedly connected to a first rotating rod. The two sets of clamping plates are respectively movably connected to the surfaces of the two sets of first rotating rods.

[0007] Preferably, a rotating column is fixedly connected to one end of each of the two sets of clamping plates, a pull plate is movably connected to the surface of each of the two sets of rotating columns, and a first strain gauge force sensor is fixedly connected to one end of each of the two sets of clamping plates.

[0008] Preferably, a second rotating rod is movably connected to one end of the surface of each of the two sets of pull plates, and a fixing block is fixedly connected to the surface of each of the two sets of second rotating rods.

[0009] Preferably, the central test assembly includes a fixing post, a mounting block, a torsion spring, and a compression plate. The fixing post is fixedly connected to the middle of one side of the surface of the fixing block, and the mounting block is fixedly connected to one end of the surface of the fixing post.

[0010] Preferably, the mounting block has three sets of third rotating rods fixedly connected inside, and the three sets of torsion springs are respectively sleeved on the surface of the three sets of third rotating rods.

[0011] Preferably, the three sets of extrusion plates are fixedly connected to the surfaces of the three sets of torsion springs, and a second strain gauge force sensor is fixedly connected to one end of the lower surface of each of the three sets of extrusion plates.

[0012] The beneficial effects of this utility model are:

[0013] 1. This utility model activates the side testing component, which tests the side of the grinding wheel body, and the center testing component also runs synchronously to test the center position of the grinding wheel body, thereby effectively improving the testing efficiency of the grinding wheel body.

[0014] 2. This utility model achieves the effect of conveniently testing the crack resistance of both sides of the grinding wheel body by means of the cylinder running, which drives the fixed block to move. During this process, the fixed block pulls the pull plate and makes the clamping plate rotate by the first rotating rod. At the same time, the pull plate rotates by the rotating column and the second rotating rod, so that the two sets of clamping plates are clamped on both sides of the grinding wheel body. The first strain gauge force sensor is used to test the grinding wheel (the strain gauge force sensor converts the force signal into an electrical signal through an elastic element, a resistance strain gauge and a measuring circuit, and has the advantages of high accuracy and fast response).

[0015] 3. When the cylinder is running, it will drive the mounting block to move. When the mounting block passes through the central hole, it will cause the three sets of extrusion plates to fold to one side. After passing through, the torsion spring will drive the three sets of extrusion plates to reset. When the cylinder retracts, it will drive the extrusion plates and the second strain gauge force sensor to simultaneously extrude the center part of the grinding wheel body, thus achieving the effect of facilitating crack detection of the center of the grinding wheel body.

[0022] In the following description, embodiments of the grinding wheel crack resistance testing device of the present invention will be described with reference to the accompanying drawings.

[0023] Example 1:

[0024] Figure 1-3 This invention illustrates an embodiment of a grinding wheel crack resistance testing device, comprising a side testing component 1 and a center testing component 4. The center testing component 4 is disposed at one end of the surface of the side testing component 1. Both the side testing component 1 and the center testing component 4 are detachably connected to a grinding wheel body 2. A center hole 3 is provided in the middle of the surface of the grinding wheel body 2. The side testing component 1 is used to test both sides of the grinding wheel body 2, and the center testing component 4 is used to test the center position of the grinding wheel body 2.

[0025] The above solution involves activating the side test component 1 during use, which tests the side of the grinding wheel body 2. Simultaneously, the center test component 4 also runs to test the center position of the grinding wheel body 2, effectively improving the testing efficiency of the grinding wheel body 2.

[0026] Example 2:

[0027] refer to Figure 2 The side test assembly 1 includes a cylinder 101, a connecting plate 102, a clamping plate 104, and a fixing block 108. The connecting plate 102 is fixedly connected to one end of the surface of the cylinder 101. Both ends of the connecting plate 102 are fixedly connected to first rotating rods 103. Two sets of clamping plates 104 are movably connected to the surfaces of the two sets of first rotating rods 103. One end of the interior of each set of clamping plates 104 is fixedly connected to a rotating column 105. The surfaces of the two sets of rotating columns 105 are movably connected to a pull plate 106. One end of the interior of each set of clamping plates 104 is fixedly connected to a first strain gauge force sensor 109. One end of the surface of each set of pull plates 106 is movably connected to a second rotating rod 107. The surfaces of the two sets of second rotating rods 107 are both fixedly connected to the fixing block 108.

[0028] The above scheme is adopted: when the cylinder 101 runs, it will drive the fixed block 108 to move. During this process, while the fixed block 108 pulls the pull plate 106 and makes the clamping plate 104 rotate by the first rotating rod 103, the pull plate 106 will rotate by the rotating column 105 and the second rotating rod 107, so that the two sets of clamping plates 104 are clamped on both sides of the grinding wheel body 2. The first strain gauge force sensor 109 will be used to test the grinding wheel (the strain gauge force sensor converts the force signal into an electrical signal through an elastic element, a resistance strain gauge and a measuring circuit, and has the advantages of high accuracy and fast response). This achieves the effect of facilitating the testing of the crack resistance of both sides of the grinding wheel body 2.

[0029] Example 3:

[0030] refer to Figure 3 The central test component 4 includes a fixed column 401, a mounting block 402, a torsion spring 404, and a compression plate 405. The fixed column 401 is fixedly connected to the middle of one side of the surface of the fixed block 108, and the mounting block 402 is fixedly connected to one end of the surface of the fixed column 401. Three sets of third rotating rods 403 are fixedly connected inside the mounting block 402, and three sets of torsion springs 404 are respectively sleeved on the surface of the three sets of third rotating rods 403. Three sets of compression plates 405 are respectively fixedly connected to the surface of the three sets of torsion springs 404, and a second strain gauge force sensor 406 is fixedly connected to one end of the lower surface of each of the three sets of compression plates 405.

[0031] The above scheme is adopted: when the cylinder 101 runs, it will drive the mounting block 402 to move. When the mounting block 402 passes through the center hole 3, it will cause the three sets of extrusion plates 405 to fold to one side. After passing through, the torsion spring 404 will drive the three sets of extrusion plates 405 to reset. When the cylinder 101 retracts, it will drive the extrusion plates 405 and the second strain force sensor 406 to simultaneously extrude the center part of the grinding wheel body 2, thereby achieving the effect of facilitating crack detection of the center of the grinding wheel body 2.

[0032] Working principle: When this utility model is in use, the user moves the fixing block 108 when the cylinder 101 is running. During this process, the fixing block 108 pulls the pull plate 106 and makes the clamping plate 104 rotate using the first rotating rod 103. At the same time, the pull plate 106 rotates using the rotating column 105 and the second rotating rod 107, thereby clamping the two sets of clamping plates 104 on both sides of the grinding wheel body 2. The first strain gauge force sensor 109 is used to test the grinding wheel (the strain gauge force sensor uses an elastic element...). The device, consisting of a strain gauge and a measuring circuit, converts force signals into electrical signals, offering advantages such as high precision and fast response. When the cylinder 101 operates, it drives the mounting block 402 to move. When the mounting block 402 passes through the central hole 3, it causes the three sets of extrusion plates 405 to fold to one side. After passing through, the torsion spring 404 drives the three sets of extrusion plates 405 to reset. When the cylinder 101 retracts, it drives the extrusion plates 405 and the second strain gauge force sensor 406 to simultaneously extrude force on the center of the grinding wheel body 2.

[0033] In summary, this grinding wheel crack resistance testing device, by activating the side testing component 1, will test the side of the grinding wheel body 2, and the center testing component 4 will also operate synchronously to test the center position of the grinding wheel body 2, thereby effectively improving the testing efficiency of the grinding wheel body 2.
