All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1

[0023] See also Figure 1 , Figure 2 and Figure 4The utility model provides a technical solution: a clamping tool for processing plastic parts, comprising: a fixed plate 1, a slide plate 3, a threaded rod 9 and a motor 2, the motor 2 is installed on one side of the fixed plate 1, the two fixed plates 1 and the two motors 2 are symmetrically arranged, the two slide plates 3 are fixedly installed between the two fixed plates 1, and a slide is arranged between the two slide plates 3, each slide plate 3 is provided with an inclined surface 6, the inclined surface 6 is large and almost covers the entire upper surface, so that the waste flowing down after cutting will slide down along the inclined surface 6 and effectively make the waste fall into the waste box under the action of the baffle, the output ends of the two motors 2 are respectively fixedly connected with threaded rods 9, a slide is arranged between the two slide plates 3, and a fixed block 8 is fixedly installed in the middle of the slide. The two threaded rods 9 are fixedly connected to the two motors 2 respectively, and the two threaded rods 9 are rotatably connected to the fixed plate 1 respectively. The threaded rods 9 are arranged in the slideway, and the two threaded rods 9 are provided with a clamping assembly 7. The clamping assembly 7 includes a rotating block 14, a handshake 21, a rotating column 22 and a slider 18. The slider 18 is slidably connected to the slideway, and the slider 18 is threadedly connected to the threaded rod 9. The rotating column 22 penetrates the rotating block 14 and extends into the slider 18 and is slidably connected to the slider 18. The rotating column 22 and the slider 18 can rotate and slide. The upper surface of the rotating column 22 is fixedly connected to the lower surface of the handshake 21. The front, back, left and right sides of the rotating block 14 are respectively provided with a rectangular clamping block 26, an arc clamping block 29, a second telescopic column 4 and a toothed clamping block 28. The setting of multiple clamping blocks can select a suitable clamping block according to the shape of the plastic product.

[0024] During use, first determine the required clamping block. There may be two different clamping blocks. At this time, rotate the two clamping components 7 respectively, and then slightly lift the handshake 21 upward and rotate it so that the two clamping blocks to be used correspond to each other, release the handshake 21, and then start the motors 2 on both sides respectively, so that the two clamping components 7 move closer to the middle and clamp the plastic product. In this way, when clamping a variety of different plastic products, you only need to rotate the handshake 21 to replace the clamping block.

[0025] Embodiment 2

[0026] See also Figure 2 On the basis of the first embodiment, a plurality of third cylindrical holes 17 are opened on the left side of the rotating block 14, the second telescopic column 4 is slidably connected to the third cylindrical hole 17, a second spring 16 is arranged in the third cylindrical hole 17, one end of the second spring 16 is fixedly connected to the second telescopic column 4, and the other end of the second spring 16 is fixedly connected to the rotating block 14. The arrangement of the second spring 16 enables the second telescopic column 4 to clamp relatively fragile plastic objects, and also to clamp irregular plastic objects, so that the force on the objects during the clamping process can be controlled, and a rubber pad 27 is fixedly installed on the front of the rectangular clamping block 26, and the arrangement of the rubber pad 27 can prevent it from falling off easily when clamping a smooth object.

[0027] When the second telescopic column 4 is used to clamp an object, after the second telescopic column 4 contacts the object, the second motor 2 continues to rotate slowly. At this time, the spring will shorten and the second telescopic column 4 will contract. The greater the pressure between the second telescopic column 4 and the object, the greater the size and direction of the pressure generated between the multiple second telescopic columns 4 and the object.

[0028] Embodiment 3

[0029] See also Figure 2-Figure 3 On the basis of the second embodiment, a square groove 19 is provided on the upper surface of the slider 18, a through hole 24 is provided at the bottom of the square groove 19, a cylindrical slide groove 25 is provided on the lower surface of the through hole 24, the radius of the cylindrical slide groove 25 is greater than the radius of the through hole 24, the bottom of the rotating column 22 is rotatably connected to the limit block 23, the limit block 23 is slidably connected to the cylindrical slide groove 25, the radius of the limit block 23 is also greater than the radius of the through hole 24, and the radius of the limit block 23 is slightly smaller than the radius of the limit block 23, so that the limit block 23 can play a role The limiting function can ensure that the rotating column 22 and the slider 18 will not be separated when the handshake 21 is lifted. The rotating column 22 is slidably connected with the through hole 24, and the rotating column 22 and the through hole 24 can also rotate. A clamping block 15 is fixedly installed at the bottom of the rotating block 14. The rotating column 22 passes through the clamping block 15, and the clamping block 15 is adapted to the square groove 19. When the rotating block 14 is rotated to a suitable position, the handle is put down, and the clamping block 15 falls into the groove to ensure that the clamping block will not rotate easily during the clamping process. A third spring 20 is arranged in 25, one end of the third spring 20 is fixedly connected to the lower surface of the limit block 23, and the other end of the third spring 20 is fixedly connected to the bottom of the cylindrical slide groove 25. The third spring 20 is arranged to ensure that the card block 15 will not bounce up easily when it falls into the square groove 19, and also ensure that it will not rotate easily. A first cylindrical hole 10 and a second cylindrical hole 13 are provided on both sides of the fixed block 8. The two threaded rods 9 are rotatably connected to the two first cylindrical holes 10 respectively. The two clamping assemblies 7 are controlled by two threaded rods 9, one end of the two threaded rods 9 is rotatably connected to the fixed block 8, and there is no contact between the two threaded rods 9. The first telescopic columns 11 are slidably connected in the two second cylindrical holes 13, and the first springs 12 are fixedly connected in the two first telescopic columns 11. The first telescopic columns 11 and the first spring are arranged to prevent the slider 18 from colliding with the fixed block 8 when the clamped object is small or when only one clamping assembly 7 is moved. The first spring 12 plays a certain buffering role, which effectively protects the equipment.

[0030] In actual use, first select a suitable clamping block according to the shape and material of the object, and then lift the handshake 21 upwards. At this time, the handshake 21 will move upwards with the rotating block 14, the card block 15, the limit block 23 and the rotating column 22 until the card block 15 is out of the square groove 19. The handshake 21 can be rotated. When it is rotated to a suitable position, release the handshake 21 and make the card block 15 clamped in the square groove 19 again. Once the card block 15 is clamped in the square groove 19, the handshake 21 can no longer be rotated. Then take the object to be clamped, and start the two motors 2, so that the two clamping assemblies 7 slowly approach and clamp the plastic product. After replacing the plastic product, you only need to adjust the clamping block. Therefore, when the utility model faces the need to clamp a variety of plastic products, there is no need to frequently replace the clamping device.
