DETAILED DESCRIPTION
[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] This specific implementation is a clamp to prevent damage by clamping, and its structural schematic diagram is as follows Figure 1 , Figure 2 As shown, it includes a clamping platform 1, a clamping mechanism 3 and a driving motor 2. The clamping mechanism 3 is symmetrically distributed in two groups on the upper surface of the clamping platform 1. The driving motor 2 is fixedly installed on the outer wall of the clamping platform 1 corresponding to the two groups of clamping mechanisms 3. A sliding groove 4 is horizontally opened on the upper surface of the clamping platform 1.
[0024] Reference Figure 3 The clamping mechanism 3 includes a moving block 7, a moving plate 11, and a clamping plate 12. The moving block 7 is slidably mounted on the upper surface of the clamping table 1. The interior of the moving block 7 is hollow and a limiting inner plate 9 is slidably mounted. The limiting inner plate 9 is vertically arranged. One end of the moving plate 11 extending into the interior of the moving block 7 is fixedly connected with a spring 10. There are multiple groups of springs 10 distributed horizontally at intervals. A buffer strip 14 is provided on the inner wall of the clamping plate 12. Since the surface of the clamping plate 12 is provided with a buffer strip 14, it has a certain protective effect when in contact with the workpiece. The end of the limiting inner plate 9 away from the spring 10 is rotatably connected with an adjusting screw 6, and the adjusting screw 6 is threadedly connected to the moving block 7. A threaded hole for the adjusting screw 6 to thread through is provided on the side wall of the moving block 7. A sliding bottom block 15 is protruding from the bottom of the moving block 7, and the sliding bottom block 15 penetrates into the slide groove 4.
[0025] Reference Figure 4, a screw is rotatably installed inside the slide groove 4, a connecting hole 16 adapted to the screw is provided on the sliding bottom block 15, and the driving motor 2 is connected to the screw. The other end of the spring 10 fits the limiting inner plate 9, and the clamping plate 12 is fixedly connected to the moving plate 11. A moving groove 8 is provided on the side wall of the moving block 7, and the moving plate 11 slides into the moving block 7 along the moving groove 8. The adjusting screw 6 spirals in or out along the moving block 7, and the limiting inner plate 9 slides along the inside of the moving block 7, so that the contact position between the spring 10 and the limiting inner plate 9 changes. When the limiting inner plate 9 is close to the clamping plate 12, the compression movement space of the spring 10 is smaller, and when the limiting inner plate 9 is away from the clamping plate 12, the compression movement space of the spring 10 is larger, and the buffering force of the clamping plate 12 is better, which is suitable for hollow tubular workpieces with lower thickness. Thanks to the setting of the clamping mechanism 3, when clamping the workpiece, it has a buffering effect to avoid direct pressure on the workpiece and causing damage. The limiting inner plate 9 slides along the inside of the moving block 7, so that the contact position between the spring 10 and the limiting inner plate 9 changes. When the limiting inner plate 9 is close to the clamping plate 12, the compressed moving space of the spring 10 is smaller. When the limiting inner plate 9 is away from the clamping plate 12, the compressed moving space of the spring 10 is larger, and the buffering force of the clamping plate 12 is better. It is suitable for hollow tubular workpieces with lower thickness. The principle is simple and easy to implement, and can effectively meet the clamping needs of weak workpieces.
[0026] Working principle: When in use, first place the workpiece on the clamping table 1, then start the driving motor 2, and the driving motor 2 drives the screw in the moving groove 8 to rotate, the sliding bottom block 15 slides along the moving groove 8, and drives the upper moving block 7 to move, when the moving block 7 is moved by force, it drives the clamping plate 12 to approach the workpiece and clamp the workpiece. Since the surface of the clamping plate 12 is provided with a buffer strip 14, it has a certain protective effect when it contacts the workpiece, and after the clamping plate 12 contacts the workpiece, the moving plate 11 is forced to slide toward the inside of the moving block 7, and the spring 10 is compressed by force to buffer the clamping plate 12. As the clamping plate 12 continues to move, the spring 10 is gradually compressed to the tightest state, and then when clamping the workpiece, it has a buffering effect to avoid direct pressure on the workpiece to cause damage;
[0027] The position of the limiting inner plate 9 can be adjusted according to the degree of pressure buffering of the workpiece, and then the tightening spacing of the spring 10 can be adjusted. By turning the adjusting screw 6, the adjusting screw 6 spirally enters or moves out along the moving block 7, and the limiting inner plate 9 slides along the inside of the moving block 7, so that the contact position between the spring 10 and the limiting inner plate 9 changes. When the limiting inner plate 9 is close to the clamping plate 12, the compression movement space of the spring 10 is smaller, and when the limiting inner plate 9 is far away from the clamping plate 12, the compression movement space of the spring 10 is larger, and the buffering force of the clamping plate 12 is better, which is suitable for hollow tubular workpieces with lower thickness;
[0028] The moving plate 11 slides horizontally inside the moving block 7 and will not fall out of the moving block 7 .
[0029] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein.
