[0025] For the purpose of making the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the accompanying drawings of the embodiments of the present utility model will be combined below Figures 1-4 to clearly and completely describe the technical solutions of the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present utility model fall within the scope of protection of the present utility model.
[0026] Such as Figures 1-4As shown in the figure: This embodiment provides a grinding machine fixture, including a support 100. A mounting frame 101 is fixedly connected to the top of the support 100. A limiting component 200 is arranged on one side of the mounting frame 101. The limiting component 200 includes a screw rod 201. The screw rod 201 is threadedly connected to the middle of the side of the mounting frame 101 close to the first clamping block 102. One end of the screw rod 201 close to the first clamping block 102 is rotatably connected to the middle of the first clamping block 102. A convex block is fixedly connected to the middle of the other end of the screw rod 201. The bottom of the first clamping block 102 is in contact with the top of the support 100. Adjusting components 300 are arranged on the top of both the first clamping block 102 and the mounting frame 101. The adjusting component 300 includes an adjusting column 301. Adjusting columns 301 are threadedly connected to the centers of the tops of both the first clamping block 102 and the mounting frame 101. Second clamping blocks 103 are threadedly connected to the tops of the adjusting columns 301. Prismatic blocks are fixedly connected to the middles of the threaded columns. Fixing grooves 104 are formed on one side of each of the first clamping block 102, the second clamping block 103, and the mounting frame 101. The openings of the fixing grooves 104 all face the middle of the support.
[0027] By rotating the convex block to drive the screw rod 201 to rotate, relative movement can be generated between the screw rod 201 and the first clamping block 102 and the mounting frame 101, so that one end of the screw rod 201 can push the first clamping block 102 to move along the axial direction of the screw rod 201, thereby adjusting the position of the first clamping block 102 and adjusting the distance between the fixing groove 104 on the first clamping block 102 and the fixing groove 104 on the mounting frame 101 until the column to be polished is clamped between the first clamping block 102 and the mounting frame 101. Through this adjustment method, the grinding machine fixture can adapt to columns of different diameters, improving the versatility and flexibility of the fixture.
[0028] After being fixed, by rotating the prismatic block, the adjusting column 301 can be driven to rotate. As the adjusting column 301 rotates, the connection between the top of the adjusting column 301 and the second clamping block 103 can be made deeper, thereby adjusting the height of the second clamping block 103. During this process, relative movement is also generated between the bottoms of the two adjusting columns 301 and the mounting frame 101 or the first clamping block 102 respectively, making the bottoms of the adjusting columns 301 penetrate deeper into the mounting frame 101 or the first clamping block 102 until the heights of the two second clamping blocks 103 are adjusted to appropriate positions. The distance between the first clamping block 102, the mounting frame 101, and the second clamping block 103 can be adjusted according to the length of the column to be polished, ensuring that columns of different lengths can be firmly clamped in the fixture, and the column to be polished is fixed and clamped at multiple points. The first clamping block 102, the mounting frame 101, and the second clamping block 103 provide sufficient clamping force for the column, effectively reducing the shaking generated at the top of the column during the grinding process and ensuring the accuracy and stability of the grinding process.
[0029] The adjusting component 300 is as Figure 2 、3 As shown
[0030] The adjusting assembly 300 further includes guide posts 302. A plurality of guide posts 302 arranged in an array are fixedly connected to the top of the mounting bracket 101 and the top of the first clamping block 102. A plurality of guide grooves 303 arranged in an array are formed at the bottom of the second clamping block 103. Clamping plates 306 are fixedly connected to the tops of the guide posts 302. The clamping plates 306 are circular, and the diameter of the clamping plates 306 is equal to the inner diameter of the guide grooves 303. The clamping plates 306 are all slidably connected to the adjacent guide grooves 303. Limiting posts 304 are fixedly connected to the centers of the tops of the clamping plates 306. Limiting grooves 305 are formed at the tops of the guide grooves 303. The diameter of the limiting posts 304 is equal to the inner diameter of the limiting grooves 305. The limiting posts 304 are all slidably connected to the limiting grooves 305. Springs 307 are sleeved on the middle parts of the limiting posts 304. The diameter of the springs 307 is smaller than the diameter of the guide grooves 303, and the diameter of the springs 307 is larger than the diameter of the limiting grooves 305;
[0031] When the adjusting column 301 is adjusted, as the height of the second clamping block 103 changes, the clamping plates 306 at the tops of the guide posts 302 will slide along the guide grooves 303 to provide guidance for the movement of the second clamping block 103. At the same time, the limiting posts 304 will also slide along the adjacent limiting grooves 305 to make the movement of the second clamping block 103 more stable and improve the stability of the second clamping block 103 during the grinding process. The top of the spring 307 fits against the inner wall of the top of the guide groove 303, and the spring 307 is always in a contracted state. The spring 307 provides a certain buffer and support for the second clamping block 103, so that the second clamping block 103 is not only guided but also supported by the elastic force of the spring 307, further improving the stability of the second clamping block 103. At the same time, the spring 307 can absorb part of the vibration force received by the second clamping block 103 during the grinding process, effectively reducing the unnecessary wear of the machine parts caused by vibration, and improving the working stability of the second clamping block 103 and prolonging its service life
[0032] The fixing bracket 105 is as Figure 4 shown
[0033] Fixing brackets 105 are connected to the middle parts of the fixing grooves 104 by bolts. A plurality of anti-slip blocks 106 arranged in an array are fixedly connected to one side of the fixing brackets 105. The anti-slip blocks 106 are made of rubber;
[0034] Contact with the polished cylinder through the fixing frame 105. When the fixing frame 105 is worn, it can be replaced by turning the bolt instead of replacing the whole clamping block, which improves the maintainability of this device and reduces the maintenance cost. The anti-slip block 106 increases the friction between the fixing frame 105 and the cylinder, prevents the cylinder from slipping during the grinding process, and ensures the stability and safety of clamping. During the grinding process, the fixing frame 105 and the anti-slip block 106 work together to ensure the stability of the cylinder in the fixture. The anti-slip block 106 can absorb and disperse the vibration generated by the cylinder during the grinding process, reduce the impact on machine components, and extend the service life of the equipment.
[0035] Working principle:
[0036] The screw rod drives the first clamping block to move by rotation, adjusts the distance between the first clamping block and the mounting frame, so that the cylinder to be ground is clamped between the first clamping block and the mounting frame to achieve preliminary fixation. The rotating prism drives the adjusting column to rotate, and then adjusts the height of the second clamping block to adapt to the length of the cylinder. The guiding column and the clamping plate provide guidance, and the limiting column is slidably connected with the limiting groove to enhance stability. The spring provides buffering and support for the second clamping block to improve the stability of the second clamping block. The anti-slip block increases the friction between the fixing frame and the cylinder to prevent the cylinder from slipping during the grinding process.
[0037] In addition, it should be noted that in the description of the present utility model, unless otherwise clearly defined and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.
[0038] The above is the preferred embodiment of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
