[0002] In the production and processing of many plastic parts, in order to limit the position of the plastic parts and ensure the stability during subsequent processing, a plastic parts processing clamping structure is needed to achieve the clamping and positioning of the plastic parts. For example, the existing patent with publication number CN214651901U discloses "a clamping mechanism for plastic product processing, which includes a box body, a bidirectional screw is rotatably connected inside the box body, and the outer surface of the bidirectional screw is threadedly connected to two threaded sleeves a arranged in opposite directions, and the top side wall of the box body is fixed with two symmetrically arranged support plates, the inner part of the support plate is rotatably connected to a threaded rod, and the outer surface of the threaded rod is threadedly connected to a threaded sleeve b". It can be seen that the application describes a common plastic parts processing clamping structure, which can achieve the clamping and limiting of plastic parts by relying on two clamping plates;

[0003] However, in actual use, the plastic parts processing clamping structure in the above patent has no protective structure designed on the clamping plate, and the plastic parts themselves are relatively brittle. The clamping plate is easy to cause extrusion damage to the surface of the plastic parts during the actual clamping process, affecting the yield rate of the product. At the same time, the height of the clamping plate cannot be adaptively adjusted according to different processing requirements, and its practicality is poor. Therefore, the utility model needs to improve and optimize the existing plastic parts processing clamping structure. Utility Model Content

[0021] 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.

[0022] Example

[0023] See also Figures 1 to 4 , is an embodiment of the utility model, which provides a technical solution: a plastic parts processing clamping structure, including

[0024] A processing table 1, two lifting seats 2 penetrating the top of the processing table 1, and side notches 4 opened on the two side surfaces of the processing table 1;

[0025] The clamping plate assembly arranged at the top of the lifting seat 2 includes a clamping plate 32, a threaded rod 31 rotatably mounted on one side surface of the clamping plate 32 through a rotating shaft, and the end of the threaded rod 31 passes through the other side of the lifting seat 2, and a guide rod 34 is welded and fixed to the surface of one side of the clamping plate 32 relative to the bottom of the threaded rod 31, and the end of the guide rod 34 also passes through the other side of the lifting seat 2, and a protective rubber pad 33 is installed on the other side surface of the clamping plate 32, and a disassembly structure is provided between the clamping plate 32 and the protective rubber pad 33. When actually used, the plastic part is placed between the two clamping plates 32, and then the threaded rod 31 is rotated and twisted. Under the action of the thread, the threaded rod 31 is horizontally displaced, and the clamping plate 32 and the protective rubber pad 33 are moved toward the plastic part until the two clamping plates 32 can clamp the plastic part and make the protective rubber pad 33 close to the surface of the plastic part, so as to complete the clamping of the plastic part during processing, and the protective rubber pad 33 can prevent the clamping plate 32 from directly contacting the plastic part, thereby preventing the surface of the plastic part from being damaged during the subsequent clamping process;

[0026] An adjusting mechanism 5 is arranged between the lifting seat 2 and the processing table 1 , and the bottom end of the lifting seat 2 penetrates to the bottom of the processing table 1 .

[0027] Among them, the threaded rod 31 is threadedly connected to the lifting seat 2, and a handle is fixed at the end of the threaded rod 31 to facilitate the subsequent rotation and twisting of the threaded rod 31. A threaded hole and a guide hole are opened on the top surface of the lifting seat 2. The guide rod 34 passes through the guide hole for the smooth penetration of the guide rod 34, and the threaded hole is for the penetration of the threaded rod 31.

[0028] The disassembly and assembly structure includes two triangular blocks 321 respectively fixed on the upper and lower surfaces of the clamping plate 32, and rectangular slots 331 provided on the upper and lower inner walls of the protective rubber pad 33 and corresponding to the triangular blocks 321. The triangular blocks 321 are embedded in the rectangular slots 331 to ensure the installation stability of the protective rubber pad 33. The disassembly and assembly structure also includes two positioning blocks 332 provided on the inner surface of the protective rubber pad 33, and a positioning slot 322 provided on the surface of the clamping plate 32 and corresponding to the positioning blocks 332. The protective rubber pad 33 and The positioning blocks 332 are all made of rubber material. The positioning blocks 332 are inserted into the positioning slots 322 to further limit the protective rubber pad 33. When the protective rubber pad 33 needs to be removed later, the upper and lower ends of the protective rubber pad 33 need to be forcefully pried apart to move the triangular block 321 out of the rectangular slot 331. The protective rubber pad 33 is no longer limited. The protective rubber pad 33 is then moved sideways to move the positioning blocks 332 out of the positioning slots 322. The protective rubber pad 33 can then be quickly removed for replacement.

[0029] The adjusting mechanism 5 includes an inner slide groove 53 provided inside one side of the processing table 1, an inner slider 54 and a spring 57 installed in the inner slide groove 53, a side clamping rod 55 welded and fixed to the surface of one side of the inner slider 54, a plurality of limit clamping holes 56 provided on the surface of the lifting seat 2, two pull rods 52 fixed to the other side surface of the inner slider 54 and penetrating into the side notch 4, and a pull plate 51 located in the side notch 4 and fixed to the two pull rods 52. The end of the side clamping rod 55 penetrates into one of the limit clamping holes 56. When the height of the lifting seat 2 and the clamping plate assembly actually needs to be adjusted, only the side of the pull plate 51 needs to be pulled. By pulling, the pull rod 52 moves the inner slider 54 sideways, and the spring 57 is gradually compressed until the end of the side clamping rod 55 moves out of the limit clamping hole 56, and the limit on the lifting seat 2 can be released. At this time, the lifting seat 2 can be slid up and down to adjust the height of the clamping plate assembly. When it is adjusted to a suitable height, the pull plate 51 is released, so that the spring 57 recovers under its own elastic action and pushes the inner slider 54 back, so that the end of the side clamping rod 55 can be clamped into the limit clamping hole 56 at other positions, and the lifting seat 2 can be limited again, completing the height adjustment of the clamping plate assembly to meet the processing and clamping requirements of different plastic parts.

[0030] Among them, a cylindrical groove is opened on the other side surface of the inner sliding block 54, and one end of the spring 57 is inserted into the cylindrical groove, which can limit the spring 57 and prevent the position of the spring 57 from being offset.

[0031] The inner wall of the side notch 4 is provided with two rod holes communicating with the inner slide groove 53 , and the rod holes correspond to the pull rod 52 , so that the pull rod 52 can pass through smoothly.

[0032] Although the embodiments of the present invention have been shown and described (see the above detailed description for details), it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
