[0002] Grinding equipment consists of a grinding equipment body, a grinding disc, a connecting column, and an adjusting device. It is a high-efficiency and precision grinding device mainly used for grinding the workpiece and is quite common in existing technology.

[0003] Existing technologies, such as the utility model with publication number CN211728758U, disclose an ultra-precision and high-efficiency double-sided grinding equipment for silicon wafers. This patent employs a housing with a support on one side of its top. A cylinder is mounted on the top of the support, penetrating the support and connected to an upper grinding disc at its bottom. A support base is located on the housing directly below the upper grinding disc, and a lower grinding disc is mounted on the support base. A drive wheel is positioned in the center of the lower grinding disc, connected to a transmission motor housed within the support base. A dust-collecting mechanism is located on the inner wall of the lower grinding disc, extending into the housing and communicating with a dust collection box. This utility model, through its dust-collecting mechanism, allows the dust-collecting holes to absorb the grinding dust. Because the dust-collecting holes are arranged in a circle, dust can be collected from every angle. Furthermore, the filter screen and activated carbon screen are mounted inside the dust collection box via support blocks, facilitating disassembly and cleaning, thus improving the dust collection efficiency of the dust collection box.

[0004] The inventors discovered in their daily work that the process of fixing the workpiece to the connecting column is cumbersome because existing methods use wax or adhesives, which leads to low work efficiency. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0027] Please see Figure 1 and Figure 2The present invention provides a high-efficiency precision grinding device, comprising: a grinding device body 1, a grinding disc 2 and an adjustment device 4 installed inside the grinding device body 1, a connecting column 5 installed inside the adjustment device 4, and a fixing structure 3 provided on the lower surface of the connecting column 5.

[0028] In the embodiments of this utility model, please refer to Figure 3 and Figure 4 The fixed structure 3 includes a fixed plate 301, which is fixedly connected to the connecting column 5. The inner wall of the fixed plate 301 has two limiting grooves 302. The inner walls of the two limiting grooves 302 are rotatably connected to a lead screw 304. The lead screw 304 is rotatably connected to the fixed plate 301. The inner wall of the lead screw 304 is fixedly connected to a rotating rod 308. The arc surfaces at both ends of the lead screw 304 are provided with opposite threads. The inner wall of the limiting groove 302 is slidably connected to a moving block 310. The moving block 310 is threadedly connected to the lead screw 304. The side of the fixed plate 301 away from the connecting column 5 is fixedly connected to a fixed column 305. The inner wall of the fixed column 305 is threadedly connected to a rotating column 313. The end of the rotating column 313 away from the fixed column 305 is fixedly connected to a support plate 307. When personnel need to use the grinding equipment body 1 to grind the workpiece, they can easily fix the workpiece on the connecting column 5, thereby improving work efficiency. Two anti-slip sleeves 309 are fixedly connected to the arc surface of the rotating rod 308. The anti-slip sleeves 309 have a hollow circular cross-section. The anti-slip sleeves 309 increase the friction between the personnel's hands and the rotating rod 308, preventing slippage during rotation. Several auxiliary rods 306 are fixedly connected to the side of the support plate 307 near the rotating column 313. The auxiliary rods 306 have a circular cross-section. The auxiliary rods 306 facilitate rotation of the support plate 307, improving operational convenience. Two limiting rods 303 are fixedly connected to the inner wall of the limiting groove 302, and the limiting rods 303 are slidably connected to the moving block 310. The limiting rod 303 can limit the movement block 310, preventing it from shifting during sliding on the inner wall of the limiting groove 302. Protective pads 312 are fixedly connected to the sides of the two extrusion plates 311 that are close to each other. The protective pads 312 have a rectangular cross-section. The protective pads 312 protect the workpiece being ground, preventing contact between the workpiece and the extrusion plates 311. The extrusion plates 311 are made of stainless steel. Stainless steel has high strength and good wear resistance, preventing deformation of the extrusion plates 311 during short-term use.

[0029] The working principle of the high-efficiency precision grinding equipment provided by this utility model is as follows: When a person needs to grind a workpiece, the person first needs to fix the workpiece on the connecting column 5, then install the connecting column 5 on the adjusting device 4, and finally operate the grinding equipment body 1 to perform the grinding operation. When the person needs to fix the workpiece on the connecting column 5, the person can first adjust the height of the support plate 307 according to the thickness of the workpiece. When adjusting the height of the support plate 307, the person can first rotate the auxiliary rod 306. 306 drives the support plate 307 to rotate. The auxiliary rod 306 facilitates rotation of the support plate 307, improving operational convenience. Then, the support plate 307 drives the rotating column 313 to rotate, which in turn moves the support plate 307 away from the fixed plate 301 until it reaches a suitable position. The operator then moves the workpiece to be ground, placing it on the side of the support plate 307 away from the fixed plate 301. Finally, the operator uses the anti-slip sleeve 309 to rotate the rotating rod 308. 9. This increases the friction between the operator's hand and the rotating rod 308, preventing slippage during rotation. The rotating rod 308 then drives the lead screw 304 to rotate, which in turn moves the two moving blocks 310 closer together. The moving blocks 310 slide on the arc surfaces of the two limiting rods 303, which limit the moving blocks 310 and prevent misalignment during sliding on the inner wall of the limiting groove 302. The moving blocks 310 then drive the pressing plate 311 closer to the support. The disc 307 moves in the direction of the pressing plate 311, which drives the protective pad 312 to move closer to the supporting disc 307. The protective pad 312 can protect the workpiece being ground and prevent it from contacting the pressing plate 311 until the two protective pads 312 come into contact with the workpiece. The pressing plate 311 is made of stainless steel, which has high strength and good wear resistance, and can prevent the pressing plate 311 from deforming during short-term use. At this point, the connecting column 5 can be installed on the adjusting device 4 to perform the grinding operation on the workpiece.

[0030] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0031] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
