It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Example 1: Please refer to Figures 1 to 5 This utility model provides a technical solution: a workpiece clamping mechanism for impact testing in modified plastic production, the workpiece clamping mechanism for impact testing in modified plastic production includes: a support plate 1, an impact device 2 and a positioning seat 3 are provided on the surface of the support plate 1, a threaded hole is provided on the side of the positioning seat 3, a positioning screw 4 is screwed into the threaded hole, a clamping plate 5 is provided on the end face of the positioning screw 4, a clamping groove 6 is provided on the surface of the positioning seat 3, and a positioning groove 7 is provided on the surface of the clamping groove 6;

[0023] Limiting block 8, with positioning rod 9 inside limiting block 8, and moving screw 10 screwed into limiting block 8;

[0024] When it is necessary to conduct an impact test on the modified plastic, the modified plastic can first be placed in the clamping groove 6. Then, the positioning screw 4 can be rotated to push the clamping plate 5 in conjunction with the limiting block 8 to position and clamp the modified plastic. When it is necessary to position and clamp modified plastics of different sizes, the positioning rod 9 can be pulled out from the positioning groove 7, so as to facilitate the movement of the limiting block 8 and thus facilitate the positioning of modified plastics of different widths.

[0025] Example 2: Based on Example 1, in order to facilitate the positioning and clamping of modified plastics of different widths, a limiting block 8 is set. The positioning seat 3 is fixedly connected to the surface of the support plate 1 by limiting bolts. The impact device 2 is a common device for impacting modified plastics. Multiple sets of positioning grooves 7 are opened on the surface. The multiple sets of positioning grooves 7 are arranged linearly at equal intervals with respect to the clamping groove 6. The positioning groove 7 has a circular plate structure. The side of the limiting block 8 is provided with a placement groove 15. The surface of the placement groove 15 is provided with a through hole. The positioning rod 9 is inserted into the through hole. One end of the positioning rod 9 is inserted into the positioning groove 7.

[0026] In use, the clamping plate 5 can be pushed by rotating the positioning screw 4, which allows the modified plastic to be positioned and clamped by the cooperation of the clamping plate 5 and the limiting block 8, making it convenient to conduct impact tests. When it is necessary to position modified plastics of different widths, the positioning rod 9 can be pulled up to disengage it from the positioning groove 7. Then the limiting block 8 can be displaced. The positioning rod 9 can be inserted into the positioning groove 7 of another group to change the distance between the limiting block 8 and the side of the clamping groove 6, thus making it convenient to position modified plastics of different widths.

[0027] Example 3: Based on Example 2, in order to increase the stability of the modified plastic after positioning, a movable screw 10 is provided. A first bearing 11 is provided on the end face of the movable screw 10. There are two sets of movable screws 10.

Guide plates 14 are provided on the sides of both the auxiliary plate 13 and the fixed plate 12. The guide plates 14 can be displaced within the limiting block 8.

[0028] When the modified plastic is positioned by the cooperation of the limiting block 8 and the clamping plate 5, the moving screw 10 can be rotated with the first bearing 11, thereby driving the fixed plate 12 and the auxiliary plate 13 to move. The cooperation of the fixed plate 12 and the auxiliary plate 13 can limit the two sides of the modified plastic, thereby increasing the clamping stability of the modified plastic. The guide plate 14 also avoids the problem of the fixed plate 12 and the auxiliary plate 13 rotating when the two sets of moving screws 10 are rotated.
