Description

Technical Field

[0001] This utility model relates to the field of screw grinding technology, and in particular to a clamping device for screw grinding. Background Technology

[0002] A screw is a cylindrical part with helical grooves cut on its outer surface or a conical part with conical helical grooves cut on its outer surface. It is connected to a nut or other threaded part by threads. It is a basic part used to fix or reinforce mechanical equipment. Its characteristics are simple production and processing and wide applicability. In the processing, the screw needs to be ground. Generally, it is fixed with a fixture and then the grinding process begins.

[0003] During the screw grinding and clamping process, some screws are quite long. After being placed in the fixture, the screw is clamped in part. After that part is ground, the screw needs to be pushed. The longer screw is heavier, and friction occurs with the fixture during the pushing process. Prolonged friction will cause wear on the fixture and will also affect the screw, making it difficult to move the screw quickly. Therefore, a clamping device for screw grinding is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a clamping device for screw grinding, which solves the aforementioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A clamping device for screw grinding includes a grinding platform with a grinding device mounted on it. Two clamping frames are fixedly installed on the top of the grinding platform. An upper clamping block is mounted on the clamping frame via a pushing component. A lower clamping block is located below the upper clamping block. A clamping linkage component is provided between the upper and lower clamping blocks. A release pushing component is provided on the lower clamping block.

[0007] Preferably, the propulsion assembly includes a telescopic cylinder fixedly mounted on the clamping and placement frame, and the output end of the telescopic cylinder is fixedly connected to the top of the upper clamping block.

[0008] Preferably, the clamping linkage assembly includes an upper adjusting rack fixedly installed on the side of the upper clamping block, a lower adjusting rack fixedly installed on one side of the lower clamping block, and a rotating gear installed on the clamping and placement frame, the rotating gear being located between the upper and lower adjusting racks.

[0009] Preferably, two sets of limiting posts are fixedly installed on the inner wall of the clamping and placement frame, and limiting blocks are fixedly installed on both sides of the upper clamping block and the lower clamping block, with the limiting blocks slidably sleeved on the limiting posts.

[0010] Preferably, an upper anti-slip pad is fixedly installed on the top inner wall of the upper clamping block.

[0011] Preferably, the release pushing assembly includes multiple bottom grooves formed on the lower clamping block, two sets of guide posts are fixedly installed in the bottom grooves, guide blocks are movably sleeved on both sets of guide posts, a rotating shaft is rotatably installed between the two guide blocks, and a contact roller is fixedly sleeved on the rotating shaft.

[0012] Preferably, the guide post is located in the bottom groove, and a compression spring is fixedly installed between the bottom of the guide block and the bottom inner wall of the bottom groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the screw grinding clamping device places the screw to be ground between the upper clamping block and the lower clamping block. The set push component can drive the upper clamping block to move down, and under the action of the clamping linkage component, drive the lower clamping block to move up, thereby clamping the placed screw, and the grinding equipment can perform grinding operations on the screw.

[0014] The release push assembly is designed so that when one part of the screw is ground, and other parts of the longer screw are ground, the upper clamping block moves upward. At this time, the screw is in the released state. The compression spring has good elasticity and can lift the contact roller. The screw is located on the contact roller. When moving the screw, only a gentle push is needed. The contact roller can reduce the pushing force and reduce the friction between the screw and the lower clamping block.

[0020] 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.

[0021] Example: Refer to Figure 1-4 A clamping device for screw grinding includes a grinding platform 1, a grinding device 2 on the grinding platform 1, two clamping placement frames 3 fixedly installed on the top of the grinding platform 1, an upper clamping block 5 installed on the clamping placement frame 3 via a pushing component, a lower clamping block 6 below the upper clamping block 5, a clamping linkage component between the upper clamping block 5 and the lower clamping block 6, and a release pushing component on the lower clamping block 6.

[0022] Specifically, the propulsion assembly includes a telescopic cylinder 4 fixedly mounted on the clamping and placement frame 3. The output end of the telescopic cylinder 4 is fixedly connected to the top of the upper clamping block 5. The screw to be ground is placed between the upper clamping block 5 and the lower clamping block 6. Then, the telescopic cylinder 4 on the propulsion assembly is activated, causing the upper clamping block 5 to move downward. The clamping linkage assembly is set up so that the movement of the upper clamping block 5 causes the upper adjusting rack 8 to move. Under the linkage of the rotating gear 10, the lower adjusting rack 9 moves, thereby causing the lower clamping block 6 to move upward, thus clamping the placed screw. The clamping linkage assembly includes a telescopic cylinder 4 fixedly mounted on the upper clamping block 5. The upper adjusting rack 8 is fixedly installed on one side of the lower clamping block 6, and the lower adjusting rack 9 is fixedly installed on one side of the clamping and placing frame 3. The rotating gear 10 is installed on the clamping and placing frame 3, and the rotating gear 10 is located between the upper adjusting rack 8 and the lower adjusting rack 9. The screw to be ground is placed between the upper clamping block 5 and the lower clamping block 6. Then, the telescopic cylinder 4 on the propulsion assembly is activated to drive the upper clamping block 5 to move down. The clamping linkage assembly is set up so that the movement of the upper clamping block 5 drives the movement of the upper adjusting rack 8. Under the linkage action of the rotating gear 10, the lower adjusting rack 9 is driven to move, thereby driving the lower clamping block 6 to move up, so as to clamp the placed screw.

[0023] Specifically, two sets of limiting posts 11 are fixedly installed on the inner wall of the clamping and placement frame 3. Limiting blocks 12 are fixedly installed on both sides of the upper clamping block 5 and the lower clamping block 6. The limiting blocks 12 are slidably sleeved on the limiting posts 11. The limiting blocks 12 and the limiting posts 11 can vertically limit the movement of the upper clamping block 5 and the lower clamping block 6, preventing misalignment. An upper anti-slip pad 7 is fixedly installed on the top inner wall of the upper clamping block 5. With the setting of the upper anti-slip pad 7, after the upper clamping block 5 and the lower clamping block 6 clamp the screw, the screw is not easy to slip under the action of friction.

[0024] Specifically, the release push assembly includes multiple bottom grooves 13 formed on the lower clamping block 6. Two sets of guide posts 14 are fixedly installed in the bottom grooves 13, and guide blocks 15 are movably sleeved on each of the two sets of guide posts 14. A rotating shaft 17 is rotatably installed between the two guide blocks 15, and a contact roller 18 is fixedly sleeved on the rotating shaft 17. The guide posts 14 are located in the bottom grooves 13, and a compression spring 16 is fixedly installed between the bottom of the guide blocks 15 and the bottom inner wall of the bottom groove 13. Under the compression and clamping action of the telescopic cylinder 4, the clamping force is relatively large. At this time, the contact roller 18 is located in the bottom groove 13 under the action of the compression force. At this time, the screw is polished by the grinding equipment 2. When grinding a longer screw in one location, it is necessary to move the screw to another location after grinding in one location. The telescopic cylinder 4 returns to its original position, and the upper clamping block 5 moves upward. At this time, the screw is in an open state. The compression spring 16 has good elasticity and can lift the contact roller 18. The compression spring 16 can be set according to the processing requirements of the factory. The weight of the screw being processed in the factory should not be able to press the contact roller 18 into the bottom groove 13. On the contrary, the screw is located on the contact roller 18. When moving the screw, it is only necessary to push the screw gently. The contact roller 18 can reduce the pushing force and reduce the friction between the screw and the lower clamping block 6. Pushing is quick and simple. After adjusting the position, it can be clamped again.

[0025] In use: When grinding the screw, place the screw to be ground between the upper clamping block 5 and the lower clamping block 6. The telescopic cylinder 4 moves the upper clamping block 5 downward, and under the linkage of the rotating gear 10, it moves the lower clamping block 6 upward, thus clamping the placed screw. At this time, the grinding equipment 2 grinds the screw. When grinding other positions of a longer screw after one position is finished, the upper clamping block 5 moves upward, and the screw is in a loose state. The compression spring 16 has good elasticity and can lift the contact roller 18. The screw is located on the contact roller 18. When moving the screw, you only need to push the screw gently. The contact roller 18 can reduce the pushing force and reduce the friction between the screw and the lower clamping block 6. Pushing is quick and simple. After adjusting the position, clamp it again. It is convenient to use.
