Technical Field
[0001] The utility model relates to the technical field of grinding wheel processing, in particular to an adjustable fixture for processing ceramic composite grinding wheels. Background Technique
[0002] The ceramic composite grinding wheel is a grinding wheel that uses ceramics as a binder to bond abrasives together. It has many pores, which is beneficial to chip removal and heat dissipation during the grinding process, is not easy to clog, and is not easy to burn the workpiece. At the same time, the ceramic bonded grinding wheel also has the advantages of good self-sharpening, long dressing interval, and good shape retention, and can grind workpieces with higher precision.
[0003] During the production process of the grinding wheel, a clamping device is required to firmly clamp it for processing operations such as grinding. In the prior art, when clamping the inner diameter of the grinding wheel, a clamping method of expanding from the inside to the outside is usually adopted. However, this single clamping method makes the grinding wheel unstable in the vertical direction. Therefore, those skilled in the art propose an adjustable fixture for processing ceramic composite grinding wheels to solve the above problems. Summary of the Utility Model
[0004] To make up for the above deficiencies, the utility model provides an adjustable fixture for processing ceramic composite grinding wheels, aiming to improve the problem that in the prior art, when clamping the inner diameter of the grinding wheel, a clamping method of expanding from the inside to the outside is usually adopted, but this single clamping method makes the grinding wheel unstable in the vertical direction.
[0005] To achieve the above object, the utility model provides the following technical solution: an adjustable fixture for processing ceramic composite grinding wheels, including a processing table and an assembly plate. Two electric telescopic rods are slidably connected to the bottom of the assembly plate. Two assembly blocks are fixedly connected to the top of the assembly plate. The bottom of the electric telescopic rod is fixedly connected with a special-shaped block. A sliding column is slidably connected to the inside of the special-shaped block. The top of the sliding column is fixedly connected with a mounting block. The bottom of the sliding column is fixedly connected with a pressing plate. A sliding rod is slidably connected to the inside of the two special-shaped blocks. A spring is sleeved on the outside of the sliding rod. A clamping assembly is installed outside the processing table.
[0006] Further, the clamping assembly includes four feet. The top of the feet is fixedly connected to the bottom of the processing table. A connecting frame is fixedly connected to the outside of the four feet.
[0007] Further, a motor is installed at the bottom of the connecting frame. The output end of the motor is fixedly connected with a threaded rod.
[0008] Further, the top of the threaded rod is rotatably connected to the bottom of the processing table. A threaded block is threadedly connected to the outside of the threaded rod.
[0009] Furthermore, four guide rods are fixedly connected inside the processing table, and sliders are slidably connected to the outer sides of the guide rods.
[0010] Furthermore, four connecting rods are rotatably connected to the outer side of the threaded block. One end of each connecting rod is rotatably connected to the bottom of a slider, and a clamping block is fixedly connected to the top of the slider.
[0011] Furthermore, two ends of the spring are respectively fixedly connected to the outer sides of two special-shaped blocks.
[0012] Furthermore, one side of the pressing plate is slidably connected to the outer side of the special-shaped block.
[0013] The utility model has the following beneficial effects:
[0014] 1. In the utility model, by starting two electric telescopic rods, the special-shaped blocks move downward. The bottom ends of the two special-shaped blocks penetrate into the inner diameter of the grinding wheel and clamp the grinding wheel. When the two electric telescopic rods contract, the bottom of the assembly plate presses against the mounting block, and the top of the grinding wheel is pressed by the pressing plate, while the special-shaped blocks support the bottom of the grinding wheel. In this way, after the grinding wheel is elastically clamped by being expanded from the inside to the outside, it can be rigidly clamped in the vertical direction. This clamping method has a better clamping effect on the grinding wheel, and the electric telescopic rod is a multi-stage telescopic rod, which can adjust the height of the grinding wheel, making the processing operation more flexible.
[0015] 2. In the utility model, by placing the grinding wheel on the top of the processing table and starting the motor, the threaded rod can be driven to rotate, so that the four connecting rods move under the drive of the threaded block. The connecting rods can make the four clamping blocks approach to clamp the outer side of the grinding wheel firmly, so as to stably clamp the outer side of the grinding wheel and assist the operation of clamping the inner diameter of the grinding wheel.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0022] Refer to Figures 1 - 3 , an embodiment provided by the present invention: an adjustable fixture for processing a ceramic composite grinding wheel, including a processing table 1 and an assembly plate 2. The assembly plate 2 is located directly above the center of the processing table 1. Two electric telescopic rods 4 are slidably connected to the bottom of the assembly plate 2. The electric telescopic rods 4 are multi-stage telescopic type. Two assembly blocks 3 are fixedly connected to the top of the assembly plate 2. The bottom of the electric telescopic rod 4 is fixedly connected with a special-shaped block 5. Four clamping blocks 19 can push the grinding wheel to the center of the processing table 1. Then, start the two electric telescopic rods 4 to make the special-shaped block 5 move downward. When the bottom ends of the two special-shaped blocks 5 penetrate into the inner diameter of the grinding wheel, they will be squeezed and approach each other. When the grinding wheel passes through the inclined surface of the special-shaped block 5, under the action of the spring 10, the concave surfaces of the two special-shaped blocks 5 will clamp the grinding wheel.
[0023] Refer to Figures 1 - 3 , a sliding column 6 is slidably connected to the inner side of the special-shaped block 5. The top of the sliding column 6 is fixedly connected with a mounting block 7. The bottom of the sliding column 6 is fixedly connected with a pressure plate 8. A sliding rod 9 is slidably connected to the inside of the two special-shaped blocks 5. One side of the pressure plate 8 is slidably connected to the outside of the special-shaped block 5. The special-shaped block 5 can limit the pressure plate 8. A spring 10 is sleeved outside the sliding rod 9. The two ends of the spring 10 are respectively fixedly connected to the outside of the two special-shaped blocks 5. After the concave surfaces of the two special-shaped blocks 5 clamp the grinding wheel, start the two electric telescopic rods 4 to contract. The bottom of the assembly plate 2 will press on the mounting block 7 and transmit the pressure to the pressure plate 8 through the sliding column 6. The pressure plate 8 can press the top of the grinding wheel, and the special-shaped block 5 will support the bottom of the grinding wheel. After the grinding wheel is elastically clamped from the inside to the outside in this way, it can be rigidly clamped in the vertical direction. This clamping method has a better clamping effect on the grinding wheel. A clamping assembly is installed outside the processing table 1.
[0024] Refer to Figures 1 - 3, the clamping assembly includes four feet 11. The feet 11 can support the processing table 1. The top of the feet 11 is fixedly connected to the bottom of the processing table 1. A connecting frame 12 is fixedly connected to the outside of the four feet 11. The connecting frame 12 is used to connect the four feet 11. A motor 13 is installed at the bottom of the connecting frame 12. The output end of the motor 13 is fixedly connected to a threaded rod 14. The top of the threaded rod 14 is rotatably connected to the bottom of the processing table 1. A threaded block 15 is threadedly connected to the outside of the threaded rod 14. Four guide rods 17 are fixedly connected inside the processing table 1. The guide rods 17 play a guiding role in the movement of the slider 18. A chute is provided inside the processing table 1 to facilitate the movement of the slider 18. The slider 18 is slidably connected to the outside of the guide rod 17. Four connecting rods 16 are rotatably connected to the outside of the threaded block 15. One end of the connecting rod 16 is rotatably connected to the bottom of the slider 18. A clamping block 19 is fixedly connected to the top of the slider 18. Place the grinding wheel on the top of the processing table 1. Starting the motor 13 can drive the threaded rod 14 to rotate, thereby causing the threaded block 15 to move. Driven by the threaded block 15, the four connecting rods 16 move. The connecting rods 16 can drive the slider 18 to move closer to the center, and then the four clamping blocks 19 move closer to clamp the outside of the grinding wheel.
[0025] Working principle: First, the assembly block 3 can be aligned and assembled at the bottom of a suitable processing equipment. Then, place the grinding wheel on the top of the processing table 1. Starting the motor 13 can drive the threaded rod 14 to rotate, thereby causing the threaded block 15 to move. Driven by the threaded block 15, the four connecting rods 16 move. The connecting rods 16 can drive the slider 18 to move closer to the center, and then the four clamping blocks 19 move closer to clamp the outside of the grinding wheel. When the inner diameter of the grinding wheel needs to be processed, this clamping mode can be adopted. In addition, the four clamping blocks 19 can push the grinding wheel to the center of the processing table 1. Then start the two electric telescopic rods 4 to make the special-shaped blocks 5 move downward. When the bottom ends of the two special-shaped blocks 5 penetrate into the inner diameter of the grinding wheel, they will be squeezed and move closer to each other. When the grinding wheel passes through the inclined surface of the special-shaped block 5, under the action of the spring 10, the concave surfaces of the two special-shaped blocks 5 will clamp the grinding wheel. When the two electric telescopic rods 4 contract, the bottom of the assembly plate 2 will press on the mounting block 7 and transfer the pressure to the pressing plate 8 through the sliding column 6. The pressing plate 8 can press the top of the grinding wheel, and the special-shaped block 5 will support the bottom of the grinding wheel. After the grinding wheel is elastically clamped from the inside to the outside in this way, it can be rigidly clamped in the vertical direction. This clamping method has a better clamping effect on the grinding wheel, and the electric telescopic rod 4 is a multi-stage telescopic rod, which can adjust the height of the grinding wheel to make the processing operation more flexible.
[0026] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
