[0002] The grinding fixtures used in the machining process of a horizontal spindle rectangular table surface grinder play a crucial role in machining accuracy and efficiency. Selecting appropriate fixtures, positioning devices, and auxiliary tools can not only improve the stability of the grinding process but also ensure the surface quality and machining accuracy of the final workpiece.

[0003] In grinding machine operation, products are typically ground by controlling the lateral movement of the grinding device. Existing grinding devices mostly achieve lateral feed by pushing the grinding head or moving the workpiece to complete the grinding operation. However, when the product surface is tilted or uneven, it can lead to depth deviations during grinding, thus affecting the grinding accuracy. Therefore, we propose a grinding fixture for horizontal spindle rectangular table surface grinders. Utility Model Content

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.

[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A grinding fixture for a horizontal spindle rectangular table surface grinder includes a grinding machine 1. A product placement plate 2 is mounted on the upper part of the grinding machine 1. A first support 4 is mounted on the rear end of the grinding machine 1 via a first lead screw 3. Activating the first lead screw 3 adjusts the height of the grinding device. A positioning frame 5 is fixedly connected to the upper part of the first support 4. A circular slider 6 is movably sleeved inside the positioning frame 5. A first motor 9 drives the circular slider 6 to adjust its angle, thereby controlling the grinding tilt angle. A horizontal plate 8 is fixedly connected to the inner side of the circular slider 6. A front and rear sliding plate 11 is provided at the front end of the horizontal plate 8. A front and rear sliding plate 11 is movably sleeved inside the front and rear sliding plate 11. The jacket 12 has a grinding protective frame 13 installed at its front end. A liquid conveying plate 16 is fixedly connected to the outside of the grinding protective frame 13. A guide pipe 17 is installed in the middle of the liquid conveying plate 16. The guide pipe 17 drives the liquid to be injected into the interior of the liquid conveying plate 16, and the liquid conveying plate 16 drives the liquid to be sprayed at the lower end, that is, the liquid is sprayed on the outside of the product. A second bracket 20 is fixedly connected to the side of the liquid conveying plate 16. A diagonal rod 21 is movably sleeved on the inner side of the second bracket 20 through a hinge. Shaping rollers 22 are set on both sides of the grinding wheel 15. The shaping rollers 22 press and limit the product being ground to improve the product grinding process and prevent deviation.

[0023] Please see Figure 2 The first bracket 4 is attached to the rear end of the grinding machine 1. The first bracket 4 is located in the middle of the side of the grinding machine 1. The first bracket 4 is installed at the rear end of the grinding machine 1, and the first lead screw 3 is started. The first lead screw 3 drives the first bracket 4 to move up and down, that is, the first bracket 4 drives the height of the grinding device to adjust, ensuring that the grinding wheel 15 is in contact with the product placement plate 2, and the grinding wheel 15 grinds the product placed on the upper part of the product placement plate 2.

[0024] Please see Figure 5 An auxiliary gear 7 is fixedly connected to one end of a circular slider 6. A first motor 9 is installed between the two sets of first brackets 4. The gear installed at one end of the output shaft of the first motor 9 meshes with the outside of the auxiliary gear 7. The circular slider 6 is set inside the positioning frame 5. When the first motor 9 is started, the first motor 9 drives the gear to mesh with the outside of the auxiliary gear 7, thereby controlling the circular slider 6 to rotate inside the positioning frame 5. When the circular slider 6 rotates, the angle of the second lead screw 10 deflects, and the second lead screw 10 is started. The second lead screw 10 drives the grinding device to move obliquely. That is, when grinding products with bevels, it ensures that the grinding device is parallel to the bevel of the product, and avoids uneven grinding depth during the grinding process.

[0025] Please see Figure 2 The rear end of the horizontal plate 8 is equipped with a second lead screw 10 that controls the left and right movement of the front and rear sliding plates 11. The front and rear sliding plates 11 are perpendicular to the front end of the first bracket 4. By activating the second lead screw 10, the second lead screw 10 drives the front and rear sliding plates 11 to move laterally at the front end of the horizontal plate 8, thereby controlling the lateral adjustment of the grinding device and adjusting the grinding position.

[0026] Please see Figure 4 The jacket 12 is equipped with a second motor 14. A grinding wheel 15 is installed at one end of the output shaft of the second motor 14. The grinding wheel 15 is installed inside the grinding protective frame 13. The lower end of the grinding protective frame 13 has an opening. By installing the second motor 14 and the grinding wheel 15 inside the jacket 12 and the grinding protective frame 13, the jacket 12 and the grinding protective frame 13 limit the position of the second motor 14 and the grinding wheel 15. The second motor 14 controls the rotation of the grinding wheel 15. When the grinding wheel 15 rotates, it can grind the product placed at the lower end.

[0027] Please see Figure 3The other end of the guide pipe 17 is connected to a spiral pipe 18. A protective sleeve 19 is fitted onto the outside of the spiral pipe 18. The protective sleeve 19 is installed at the front end of the grinding protective frame 13. A water injection pipe is connected to the outside of the spiral pipe 18. The two ends of the liquid conveying plate 16 are located on both sides of the grinding protective frame 13. A water outlet is opened at the lower end of the liquid conveying plate 16. The liquid conveying plate 16 is installed outside the grinding protective frame 13, and the liquid is transported through the spiral pipe 18. The spiral pipe 18 delivers the liquid to the liquid conveying plate 16 via the guide pipe 17. Inside, the liquid is sprayed downwards from both sides of the liquid conveying plate 16, that is, the liquid is sprayed on the lower end of the grinding area, which can cool the product. After the liquid is sprayed on the grinding area, it prevents the dust generated after grinding from spreading everywhere. At the same time, the spiral tube 18 is attached to the outside of the grinding protective frame 13, which is set outside the grinding wheel 15. During the liquid transmission, the spiral tube 18 can cool down the heat generated by the rotation of the grinding wheel 15, preventing the heat generated by the grinding wheel 15 from being conducted and causing heat damage to the structure.

[0028] Please see Figure 3 A limiting block is installed on the inner side of the second bracket 20. The limiting block is located inside the inclined rod 21. A shaping roller 22 is movably sleeved inside the lower end of the inclined rod 21. A spring 23 is installed between the second bracket 20 and the inclined rod 21. The spring 23 is set on both sides of the grinding wheel 15. The second bracket 20 is installed on both sides of the grinding protective frame 13. At the same time, a limiting block is installed on the inner side of the second bracket 20. The limiting block limits the downward extension range of the inclined rod 21. The spring 23 is installed on the inner side of the second bracket 20. The spring 23 pushes the inclined rod 21 to move inward, that is, the shaping roller 22 moves to both sides of the grinding wheel 15. When the product is being ground, the shaping roller 22 is in contact with the product in advance. At the same time, the shaping roller 22 presses and limits the product to ensure that the product does not shake during grinding, which would affect the grinding accuracy.

[0029] Working principle: During use, place the product on the upper part of the product placement plate 2, and simultaneously start the first lead screw 3. The first lead screw 3 adjusts the height of the grinding wheel 15, and observes the inclination angle of the product's grinding surface. Start the first motor 9, which drives the circular slider 6 to adjust the angle inside the positioning frame 5, and adjusts the front and rear sliding plates 11 laterally. The front and rear sliding plates 11 drive the product to adjust laterally, thus grinding the exterior of the product. During the grinding process, the spiral tube 18 carries the liquid to the inside of the guide tube 17, and the liquid is discharged downward through the liquid conveying plate 16, that is, the liquid is sprayed on both sides of the grinding wheel 15, which improves the cooling treatment of the ground product. At the same time, the shaping rollers 22 are set on both sides of the grinding wheel 15. During the grinding process of the grinding wheel 15, the shaping rollers 22 continuously press and limit the position of the product.
