Abstract
Description
Technical Field
[0001] This utility model relates to the field of fixture technology, specifically a fixture for preventing spline slippage in the production of long carbon fiber reinforced PA6. Background Technology
[0002] Long carbon fiber reinforcement is a composite material technology that combines long carbon fibers with thermoplastics or other matrix materials. Long carbon fiber reinforced composites exhibit high strength, high rigidity, low creep, and good fatigue resistance. For example, long carbon fiber reinforced PA6 material exhibits high rigidity, high impact resistance, and high flowability.
[0003] In the production of long carbon fiber reinforced PA6, it is necessary to check the rigidity of the product. The check is carried out by extracting test strips from the long carbon fiber reinforced PA6, clamping and fixing the test strips with a fixture, and finally using testing equipment to test the rigidity of the clamped and fixed strips.
[0004] However, the above-mentioned technical conditions also have the drawback that the clamping stability of the spline is not good enough, and the spline is prone to sliding on the clamp.
[0005] Based on this, this utility model designs a fixture for preventing the slippage of spline in the production of long carbon fiber reinforced PA6, in order to solve the above problems. Utility Model Content
[0006] The purpose of this invention is to provide a fixture for preventing the slippage of spline in the production of long carbon fiber reinforced PA6, so as to solve the above-mentioned technical problems.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a clamp for preventing slippage of spline in the production of long carbon fiber reinforced PA6, comprising a clamp, characterized in that: the clamp includes a fixing block, a clamping block, a threaded rod, and a handle; the fixing block has a fixing groove, the clamping block is inserted into the fixing groove, two clamping blocks are mirror-arranged in the fixing groove; the handle is fixedly connected to the threaded rod; the fixing groove has a threaded hole, the threaded rod is threadedly connected to the threaded hole, the threaded rod is fixedly connected to a limiting block, the threaded hole is between the limiting block and the handle; the clamping block has a limiting groove, the limiting block is located in the limiting groove; the limiting groove has a through hole, the through hole is between the threaded hole and the limiting block, the threaded rod is located in the through hole; the fixing groove is narrowed, with one end of the narrow opening facing away from the threaded hole.
[0008] Preferably, the clamping block is fixedly provided with anti-slip teeth, and multiple anti-slip teeth are provided on the clamping block. The anti-slip teeth are inclined on the clamping block, and the tips of the anti-slip teeth face the threaded hole.
[0009] Preferably, the fixing groove has an insertion groove, and the clamping block is fixedly connected to an insertion strip, which is inserted into the insertion groove.
[0010] Preferably, a stop block is connected to the fixing block, the stop block has an insertion hole, a fixing rod is inserted into the insertion hole, the fixing rod is threaded onto the fixing block, and the clamping block is between the fixing groove and the stop block.
[0011] In summary, this application has the following beneficial technical effects: When in use, the sample is placed between the two clamping blocks, and the threaded rod is tightened by tightening the handle thread to move the threaded rod downward. The two clamping blocks in the fixing groove also move downward under the action of the limiting block. Because the fixing groove is designed to be constricted, the distance between the two clamping blocks continuously decreases as the clamping blocks move downward. The sample is clamped between the two clamping blocks. By continuously tightening the threaded rod, the clamping force of the two clamping blocks on the sample can be increased, making the sample less likely to slip. At the same time, the setting of the anti-slip teeth and the setting of the direction of the anti-slip tooth tips make it even less likely for the sample to slip. The clamping stability of the sample in the fixture is better, achieving the effect of making the sample less likely to slip on the fixture. Attached Figure Description

[0019] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0020] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0021] A fixture for preventing slippage of spline in the production of long carbon fiber reinforced PA6 includes a fixture, which includes a fixing block 3, a clamping block 5, a threaded rod 2 and a handle 1. The fixing block 3 has a fixing groove 8, and the clamping block 5 is inserted into the fixing groove 8. There are two clamping blocks 5 mirror images of each other in the fixing groove 8.
[0022] Handle 1 is fixedly connected to threaded rod 2. A threaded hole 12 is provided in the fixing groove 8, and threaded rod 2 is threadedly connected to threaded hole 12. One end of threaded rod 2 is fixedly connected to limit block 9, and threaded hole 12 is between limit block 9 and handle 1. A limit groove 4 is provided at the end of clamping block 5 near threaded hole 12, and limit block 9 is located in limit groove 4, between two clamping blocks 5.
[0023] A through hole 10 is provided on the limiting groove 4, and the threaded rod 2 is located in the through hole 10, which is between the threaded hole 12 and the limiting block 9. The fixing groove 8 is designed with a narrow opening, with one end of the narrow opening facing away from the threaded hole 12. The height of the clamping block 5 is less than the height of the fixing groove 8. In the initial state, the clamping block 5 is located at one end of the threaded hole 12 of the fixing groove 8, at which time the distance between the two clamping blocks 5 is the largest, which makes it convenient to place the spline between the two clamping blocks 5.
[0024] By rotating the threaded rod 2 through the handle 1, the distance between the two clamping blocks 5 gradually decreases under the action of the limiting block 9 and the fixing groove 8, and the template is clamped and fixed between the two clamping blocks 5. Due to the shape of the fixing groove 8, the template can be subjected to a greater clamping force through the clamping blocks 5 by continuously tightening the threaded rod 2. Under the action of a greater clamping force, the template is less likely to slip.
[0025] Anti-slip teeth 6 are fixedly provided on the clamping block 5. Multiple anti-slip teeth 6 are provided on the clamping block 5. The anti-slip teeth 6 are inclined on the clamping block 5, and the tips of the anti-slip teeth 6 face the threaded hole 12. Through the setting of the anti-slip teeth 6 and the tips of the anti-slip teeth 6, the spline is not easy to slip between the two clamping blocks 5.
[0026] The fixed groove 8 has a plug groove 7, and the clamping block 5 is fixedly connected with a plug strip 11 that is compatible with the plug groove 7. The plug strip 11 is inserted into the plug groove 7. The setting of the plug strip 11 and the plug groove 7 makes the up and down movement of the clamping block 5 in the fixed groove 8 more stable.
[0027] A stop block 13 is connected to the fixing block 3. The stop block 13 has an insertion hole. A fixing rod 14 is inserted into the insertion hole. One end of the fixing rod 14 is threaded to the fixing block 3, and the other end of the fixing rod 14 is pressed against the stop block 13. The clamping block 5 is between the fixing groove 8 and the stop block 13. The stop block 13 makes it difficult for the clamping block 5 to detach from the fixing groove 8, thereby increasing the stability of the clamping block 5 in the fixing groove 8.
[0028] The implementation principle of this embodiment is as follows: When in use, the sample is placed between the two clamping blocks 5. By tightening the threaded rod 2 with the handle 1, the threaded rod 2 moves downward. Under the action of the limiting block 9, the two clamping blocks 5 in the fixing groove 8 also move downward. Because the fixing groove 8 is designed to be constricted, the distance between the two clamping blocks 5 continuously decreases as the clamping blocks 5 move downward. The sample is clamped between the two clamping blocks 5. By continuously tightening the threaded rod 2, the clamping force of the two clamping blocks 5 on the sample can be increased, making it less likely for the sample to slip. At the same time, with the setting of the anti-slip teeth 6 and the setting of the direction of the anti-slip teeth 6, the sample is even less likely to slip. The clamping stability of the sample in the fixture is better, achieving the effect of making the sample less likely to slip on the fixture.
