Description

Technical Field

[0001] This utility model relates to the field of plastic product processing technology, and in particular to a positioning fixture for processing plastic products. Background Technology

[0002] With the widespread use of plastic products in daily life and industry, the precision and efficiency of their processing technology have become crucial. In the processing of plastic products, positioning fixtures, as key equipment to ensure processing accuracy, play an indispensable role.

[0003] Some end cap plastic products have thin side walls and are made of plastic, which makes it impossible for traditional bench vises and other positioning fixtures to clamp their side walls during the coloring process. This can easily cause deformation, resulting in the plastic products being deformed and unusable after processing and clamping. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a positioning fixture for processing plastic products.

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

[0006] A positioning fixture for processing plastic products includes a mounting platform. An adjustment mechanism is provided on one side of the upper surface of the mounting platform, and a mounting seat is provided on the other side. Clamping mechanisms are symmetrically provided on both the adjustment mechanism and the mounting seat, and the clamping mechanisms on both sides are connected by a connecting mechanism.

[0007] The clamping mechanism includes a connecting base for connecting the connecting mechanism, and a clamping plate is fixedly connected to the upper surface of the connecting base for clamping the plastic cover.

[0008] In addition, a preferred structure is that rubber pads are attached to the outer surface of the clamping plate, and the outer surface of the clamping plate with rubber pads is used to clamp the plastic cap.

[0009] Furthermore, a preferred structure is that the clamping plate is L-shaped.

[0010] Furthermore, in a preferred configuration, a mounting hole is provided on the upper surface of the mounting platform on one side of the adjustment mechanism, and a mounting base is installed at the mounting hole for connection with the connecting base.

[0011] Furthermore, in a preferred configuration, the adjustment mechanism includes a servo electric cylinder, with a connecting plate connected to the piston rod end of the servo electric cylinder. The connecting plate is used to connect to the connecting base, and a mounting plate is provided at the end of the servo electric cylinder away from the output piston rod.

[0012] Furthermore, in a preferred configuration, the connecting mechanism includes a telescopic connecting rod, with both ends of the telescopic connecting rod connected to two pairs of connecting bases on the same side, and a spring sleeved on the outside of the telescopic connecting rod, with both ends of the spring connected to two pairs of connecting bases on the same side.

[0013] The beneficial effects of this utility model are as follows: This utility model uses a clamping mechanism to clamp and position a plastic cap, which is a plastic product, and uses a connecting mechanism to make the clamping mechanism open and abut against the inner wall of the plastic cap cavity. The spring and telescopic connecting rod effectively replace the traditional bench vise clamping. This positioning fixture ensures that the plastic product is clamped without causing deformation.

Detailed Implementation

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-5 A positioning fixture for processing plastic products includes a mounting platform 1. An adjustment mechanism 2 is provided on one side of the upper surface of the mounting platform 1, and a mounting seat 3 is provided on the other side. Clamping mechanisms 4 are symmetrically provided on both the adjustment mechanism 2 and the mounting seat 3. The clamping mechanisms 4 on both sides are connected by a connecting mechanism 6. The clamping mechanism 4 includes a connecting base 41, which is used to connect the connecting mechanism 6. A clamping plate 42 is fixedly connected to the upper surface of the connecting base 41. The clamping plate 42 is used to clamp a plastic cover 5. The clamping plate 42 can effectively hold the plastic cover 5.

[0022] Rubber pads 421 are attached to the outer surface of the clamping plate 42. The outer surface of the clamping plate 42 with rubber pads 421 is used to clamp the plastic cover 5. The clamping plate 42 is L-shaped. The rubber pads 421 increase the friction with the plastic cover 5 while protecting the inner wall of the plastic cover 5 from scratches.

[0023] Furthermore, a mounting hole 11 is provided on the upper surface of the mounting platform 1 on one side of the adjustment mechanism 2, and the mounting base 3 is installed in the mounting hole 11. The mounting base 3 is used to connect with the connecting base 41 and the mounting base 3 is detachable.

[0024] Meanwhile, the adjustment mechanism 2 includes a servo electric cylinder 21, and a connecting plate 23 is connected to the piston rod end of the servo electric cylinder 21. The connecting plate 23 is used to connect with the connecting base 41. An mounting plate 22 is provided at the end of the servo electric cylinder 21 away from the output piston rod. The distance between the two clamping mechanisms 4 is adjusted by the servo electric cylinder 21.

[0025] In addition, the connecting mechanism 6 includes a telescopic connecting rod 61, with both ends of the telescopic connecting rod 61 connected to two pairs of connecting bases 41 on the same side. A spring 62 is sleeved on the outside of the telescopic connecting rod 61, with both ends of the spring 62 connected to two pairs of connecting bases 41 on the same side. The spring 62 realizes the reset of the telescopic connecting rod 61.

[0026] In this embodiment, when coloring the upper surface of the plastic cover 5, the clamping mechanism 4 can be used for positioning. First, the clamping plates 42 on both sides are retracted, and the servo cylinder 21 is adjusted so that the clamping plates 42 are located in the inner cavity of the plastic cover 5. Then, the clamping plates 42 on both sides can be released. After the spring 62 releases its elastic potential energy, the telescopic connecting rod 61 extends, so that the clamping plates 42 can be pushed outward, thereby pushing them open and clamping them on the inner wall of the inner cavity of the plastic cover 5. The lateral distance is adjusted by adjusting the servo cylinder 21 so that the clamping mechanism 4 clamps the plastic cover 5.

[0027] In this utility model, the plastic cover 5, which is a plastic product, is clamped and positioned by the clamping mechanism 4, and the clamping mechanism 4 is opened and pressed against the inner wall of the inner cavity of the plastic cover 5 by the connecting mechanism 6. The spring 62 and the telescopic connecting rod 61 effectively replace the traditional bench vise clamping. This positioning fixture ensures that the plastic product is clamped without causing deformation of the plastic product.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
