Description

Technical Field

[0001] This utility model relates to the field of glazed brick technology, specifically to a glazed brick surface abrasion resistance testing machine. Background Technology

[0002] Glazed tiles are tiles whose surface has been glazed. They are thin-sheet ceramic building materials used for interior wall decoration. They are made by firing the surface with glaze. The main body is divided into two types: earthenware and porcelain. Earthenware tiles have a red back, while porcelain tiles have a grayish-white back. Glazed tiles can be decorated with various patterns and designs, making them more colorful and patterned than polished tiles. Because the surface is glazed, they are not as wear-resistant as polished tiles. Glazed tiles are usually square or irregularly shaped, with square glazed tiles being the most common.

[0003] For example, Chinese utility model patent CN219121719U discloses a test instrument that is easy to assemble and disassemble, comprising: a mounting cart, on the upper side of which a mounting frame is mounted; an oil chamber is mounted inside the oil tank, and a piston is disposed inside the oil chamber; a shock-absorbing rod is mounted at the connection between the piston and the mounting frame; a connecting frame is mounted at the rear end of the mounting cart; a pressing control module is disposed on the left side of the mounting frame; a movable block is mounted inside the mounting cart, and a support rod is disposed at the connection between the movable block and the mounting frame, and a second spring is disposed at the connection between the support rod and the movable block; a detection box is disposed inside the mounting frame, and a positioning component is mounted at the connection between the detection box and the mounting frame; and a counterweight groove is disposed on the upper side of the mounting frame. This easy-to-assemble and disassemble test instrument adopts a snap-fit ​​installation structure, which facilitates the disassembly and assembly of the instrument, and the instrument shell adopts a rotating baffle, which facilitates the maintenance of the internal electronic components.

[0004] After the glazed tiles are processed, a testing machine is needed to test the wear resistance of the glazed tile surface. However, the existing testing machine can only stably clamp square glazed tiles, and it is difficult to stably clamp irregularly shaped glazed tiles. Its poor adaptability will not only reduce the accuracy of the wear resistance test of glazed tiles, but also affect the performance of the testing machine. Utility Model Content

[0005] The purpose of this invention is to provide a tester for the surface abrasion resistance of glazed bricks, so as to solve the problem mentioned in the background art of inconvenience in clamping glazed bricks of different shapes.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a glazed tile surface abrasion resistance testing machine, comprising a testing machine body, a clamping assembly, a sliding assembly, a limiting assembly, and an adapting assembly; the testing machine body includes a worktable and a grinding block; the grinding block is connected to the worktable via a moving drive mechanism and contacts the glazed tile; the clamping assembly is arranged on the worktable; the clamping assembly includes a bearing block, a gear, a rack, and a clamping plate; two bearing blocks are symmetrically slidably disposed on the worktable via a sliding assembly; the gear is rotatably connected to the bearing blocks via a rotating shaft; two racks are symmetrically disposed on the bearing blocks via a limiting assembly and mesh with the gear for rotation; the clamping plate is fixedly connected to the end of the rack and contacts the glazed tile via the adapting assembly.

[0007] Preferably, the clamping assembly further includes a receiving groove and a spring; the receiving groove is provided in the bearing block, and the end of the rotating shaft extends into the receiving groove and is rotatably connected to the receiving groove; the spring is sleeved on the rotating shaft, and both ends of the spring are fixedly connected to the rotating shaft and the inner wall of the receiving groove, respectively.

[0008] Preferably, the sliding assembly includes a sliding groove, a bidirectional lead screw, and sliding blocks; the top surface of the worktable has a sliding groove; one end of the bidirectional lead screw is rotatably connected to the sliding groove via a rotating shaft, and the other end extends through the sliding groove to the outside; two sliding blocks are symmetrically slidably inserted into the sliding groove and fixedly connected to the bearing block, and the sliding blocks are threadedly connected to the bidirectional lead screw.

[0009] Preferably, the limiting component includes a limiting groove and a limiting block; the top surface of the bearing block has two symmetrically opened limiting grooves; the limiting block is slidably inserted into the limiting groove and fixedly connected to the rack.

[0010] Preferably, the limiting block is an isosceles trapezoidal structure with a smaller upper section and a larger lower section.

[0011] Preferably, the adaptation component includes an adaptation groove, an adaptation block, and a return spring; the clamping plate has a plurality of adaptation grooves evenly distributed on the side away from the rack; the adaptation block is slidably inserted into the adaptation groove; and the two ends of the return spring are fixedly connected to the inner wall of the adaptation groove and the adaptation block, respectively.

[0012] Preferably, the adapting block has a bullet-shaped structure, and the surface of the adapting block is in contact with the inner wall of the adapting groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, by setting up a clamping assembly and a sliding assembly, places the glazed tile on a worktable and positions it between two support blocks. Then, rotating the handwheel on the double-acting screw causes the double-acting screw to rotate through the rotating shaft and sliding groove, causing the sliding block to be threadedly connected to the double-acting screw. This allows the two sliding blocks to slide relative to each other within the sliding groove, causing the two support blocks to move relative to each other until one of the clamping plates on the support block contacts the surface of the glazed tile. At this point, the glazed tile will press against the clamping plate, causing the rack to drive the clamping plate to move. This causes the two racks to mesh with the gear and rotate, causing the gear to rotate through the rotating shaft. The spring is wound or relaxed under force, causing the two racks to move away from each other through the limiting assembly until another clamping plate on the bearing block contacts the surface of the glazed tile. Then, the grinding block is used by the testing machine body to grind the glazed tile. By observing the wear of the glazed tile, the wear resistance test of the glazed tile can be completed. Then, by rotating the handwheel on the bidirectional screw in the opposite direction, the two bearing blocks are moved away from each other to their original positions. Compared with the prior art, this utility model has a simple and reasonable structure, ingenious design, and can clamp glazed tiles of different shapes. It has high adaptability and strong stability.

[0015] 2. By setting a limiting groove and a limiting block, and setting the limiting block as an isosceles trapezoidal structure with a smaller upper part and a larger lower part, this utility model can not only fix the position of the rack on the bearing block, but also limit the range of movement of the rack, so as to prevent the rack from falling off and meshing with the gear, thereby affecting the normal use of this utility model.

[0016] 3. By setting an adaptation component, when the adaptation blocks on both bearing blocks are in contact with the surface of the glazed tile, the glazed tile will squeeze the adaptation block, causing the adaptation block to slide in the adaptation groove, and the return spring will be compressed. Since the adaptation block 502 has a bullet-shaped structure, multiple adaptation blocks can automatically adapt to the shape of the glazed tile surface to clamp the glazed tile, so as to better fit the surface shape of the glazed tile and make the clamping of the glazed tile more stable, thereby improving the practicality of this utility model.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 4 This utility model provides a technical solution: a tester for the surface abrasion resistance of glazed tiles, comprising a tester body 1, a clamping assembly 2, a sliding assembly 3, a limiting assembly 4, and an adaptation assembly 5; the tester body 1 includes a worktable 101 and a grinding block 102; the grinding block 102 is connected to the worktable 101 via a moving drive mechanism and contacts the glazed tile; the clamping assembly 2 is arranged on the worktable 101; the clamping assembly 2 includes a bearing block 201, a gear 202, a rack 203, a clamping plate 204, a receiving groove 205, and a spring 206; two bearing blocks 201 The sliding assembly 3 is symmetrically slidably mounted on the workbench 101; the gear 202 is rotatably connected to the bearing block 201 via a rotating shaft; two racks 203 are symmetrically mounted on the bearing block 201 via a limiting assembly 4 and mesh with the gear 202 for rotation; the clamping plate 204 is fixedly connected to the end of the rack 203 and contacts the glazed brick via an adapting assembly 5; a receiving groove 205 is provided in the bearing block 201, and the end of the rotating shaft extends into the receiving groove 205 and is rotatably connected to the receiving groove 205; a spring 206 is sleeved on the rotating shaft, and both ends of the spring 206 are fixedly connected to the rotating shaft and the inner wall of the receiving groove 205, respectively;

[0025] The sliding assembly 3 includes a sliding groove 301, a bidirectional lead screw 302, and a sliding block 303; the top surface of the worktable 101 has a sliding groove 301; one end of the bidirectional lead screw 302 is rotatably connected to the sliding groove 301 through a rotating shaft, and the other end extends through the sliding groove 301 to the outside; two sliding blocks 303 are symmetrically slidably inserted into the sliding groove 301 and fixedly connected to the bearing block 201, and the sliding blocks 303 are threadedly connected to the bidirectional lead screw 302.

[0026] This invention, by setting up a clamping assembly 2 and a sliding assembly 3, places the glazed brick on the workbench 101 and positions it between two support blocks 201. Then, rotating the handwheel on the bidirectional lead screw 302 causes the bidirectional lead screw 302 to rotate through the rotating shaft and the sliding groove 301, causing the sliding block 303 to be threadedly connected to the bidirectional lead screw 302. This allows the two sliding blocks 303 to slide relative to each other within the sliding groove 301, causing the two support blocks 201 to move relative to each other until one of the clamping plates 204 on the support block 201 contacts the surface of the glazed brick. At this point, the glazed brick will press against the clamping plate 204, causing the rack 203 to drive the clamping plate 204 to move. This causes the two racks 203 to mesh and rotate with the gear 202, making... The gear 202 rotates via the rotating shaft, causing the spring 206 to be wound or relaxed, and the two racks 203 move away from each other via the limiting component 4 until the other clamping plate 204 on the bearing block 201 contacts the surface of the glazed tile. Then, the grinding block 102 grinds the glazed tile through the testing machine body 1. By observing the wear of the glazed tile, the wear resistance test of the glazed tile can be completed. Then, by rotating the handwheel on the bidirectional lead screw 302 in the opposite direction, the two bearing blocks 201 move away from each other to their original positions. Compared with the prior art, this utility model has a simple and reasonable structure, ingenious design, and can clamp glazed tiles of different shapes. It has high adaptability and strong stability.

[0027] As a preferred embodiment, the limiting component 4 includes a limiting groove 401 and a limiting block 402; the top surface of the bearing block 201 is symmetrically provided with two limiting grooves 401; the limiting block 402 is slidably inserted into the limiting groove 401 and fixedly connected to the rack 203; the limiting block 402 is an isosceles trapezoidal structure with a smaller upper part and a larger lower part.

[0028] This utility model, by setting a limiting groove 401 and a limiting block 402, and setting the limiting block 402 as an isosceles trapezoidal structure with a smaller upper part and a larger lower part, can not only fix the position of the rack 203 on the bearing block 201, but also limit the range of movement of the rack 203, so as to prevent the rack 203 from falling off and meshing with the gear 202, thereby affecting the normal use of this utility model.

[0029] As a preferred embodiment, the adaptation component 5 includes an adaptation groove 501, an adaptation block 502, and a return spring 503; the clamping plate 204 has a plurality of adaptation grooves 501 evenly distributed on the side away from the rack 203; the adaptation block 502 is slidably inserted into the adaptation groove 501; the two ends of the return spring 503 are fixedly connected to the inner wall of the adaptation groove 501 and the adaptation block 502, respectively; the adaptation block 502 has a bullet-shaped structure, and the surface of the adaptation block 502 is in contact with the inner wall of the adaptation groove 501; when the side of the limiting block 402 is in contact with the inner side wall of the limiting groove 401, the rack 203 is still meshed with the gear 202, and the clamping plate 204 is not in contact with the bearing block 201.

[0030] By setting an adaptation component 5, when the adaptation blocks 502 on both bearing blocks 201 are in contact with the surface of the glazed tile, the glazed tile will squeeze the adaptation blocks 502, causing the adaptation blocks 502 to slide in the adaptation groove 501, and causing the return spring 503 to contract under force. Since the adaptation blocks 502 have a bullet-shaped structure, multiple adaptation blocks 502 can automatically adapt to the shape of the glazed tile surface to clamp the glazed tile, so as to better fit the surface shape of the glazed tile and make the clamping of the glazed tile more stable, thereby improving the practicality of this utility model.

[0031] Working principle: In use, first, place the glazed tile on the workbench 101 and position it between the two support blocks 201. Then, rotate the handwheel on the double-acting screw 302, causing the double-acting screw 302 to rotate through the shaft and slide groove 301. This causes the sliding block 303 to be threadedly connected to the double-acting screw 302, allowing the two sliding blocks 303 to slide relative to each other within the slide groove 301. This causes the two support blocks 201 to move relative to each other until the adapting block 502 on one of the clamping plates 204 on the support block 201 contacts the surface of the glazed tile. At this point, the glazed tile will press against the adapting block 502 on the clamping plate 204, causing the rack 203 to move and drive the clamping plate 204. This causes the two racks 203 to mesh and rotate with the gear 202, causing the gear 202 to rotate through the rotating shaft. This causes the spring 206 to be wound. The two racks 203 are moved away from each other by the coiling or loosening of the racks, causing the limiting block 402 to slide in the limiting groove 401 until the adapting block 502 on the other clamping plate 204 on the bearing block 201 contacts the surface of the glazed tile. At this time, the glazed tile will squeeze the adapting block 502, causing the adapting block 502 to slide in the adapting groove 501, causing the return spring 503 to contract under force. This allows multiple adapting blocks 502 to automatically adapt to the shape of the glazed tile surface and clamp it until the glazed tile contacts the clamping plate 204. Then, the grinding block 102 is used to grind the glazed tile by the testing machine body 1. By observing the wear of the glazed tile, the wear resistance test of the glazed tile can be completed. Then, by rotating the handwheel on the bidirectional lead screw 302 in the opposite direction, the two bearing blocks 201 are moved away from each other to their original positions.

[0032] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
