[0017] 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 this application. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] The following is in conjunction with the appendix Figure 1-3This application provides a further detailed description. An embodiment of this application discloses a clamping fixture for simultaneously fixing two roller side plates. It includes a base plate 1, with two positioning blocks 2 on the upper surface of the base plate 1. The line connecting the two positioning blocks 2 forms the working center line, and the position of the working center line is determined by the positions of the two positioning blocks 2. Two roller side plates 7 are clamped on both sides of the working center line. A first connecting post 3 is provided on the upper surface of the base plate 1, located on the working center line, and its extension direction is perpendicular to the upper surface of the base plate 1. A first pressing block 4 is rotatably connected to the first connecting post 3. The first pressing block 4 is strip-shaped, and the first connecting post 3 connects to the center point of the two first pressing blocks 4. The position of the first pressing block 4 is determined by the position of the first connecting post 3. By rotating the strip-shaped first pressing block 4, both ends of the first pressing block 4 can simultaneously press the roller side plates 7 on both sides of the working center line. The number of first pressing blocks 4 corresponds to the number of first connecting posts 3; more first connecting posts 3 and corresponding first pressing blocks 4 can be set according to actual conditions. A second pressure block 5 is provided on both sides of the working center line to assist the first pressure block 4 in pressing and clamping the side plate 7 of the road roller being held.

[0019] Furthermore, each of the first pressure blocks 4 has a connecting hole, and the first connecting post 3 is a threaded rod, with a clearance fit between the first connecting post 3 and the connecting hole of the first pressure block 4. A first clamping nut is threadedly connected to the first connecting post 3, and the first clamping nut is located on the side of the first pressure block 4 away from the base plate 1. By rotating the first clamping nut towards the base plate 1, the first pressure block 4 moves towards the base plate 1, achieving the clamping effect of the first pressure block 4. By rotating the first clamping nut in the opposite direction to move it away from the base plate 1, the clamping state of the first pressure block 4 is released.

[0020] Furthermore, the second pressure block 5 has a strip-shaped hole extending along its length. A second connecting post is positioned on the upper surface of the base plate 1 corresponding to the strip-shaped hole of the second pressure block 5, with the extension direction of the second connecting post perpendicular to the upper surface of the base plate 1. The position of the second pressure block 5 relative to the second connecting post is changed by the engagement of the strip-shaped hole and the second connecting post. The second connecting post is a threaded rod, with a clearance fit between it and the strip-shaped hole of the second pressure block 5. A second clamping nut is threaded onto the second connecting post, located on the side of the second pressure block 5 furthest from the base plate 1. The position of the second clamping nut relative to the second connecting post is changed by rotating the second clamping nut. When the roller side plate 7 needs to be placed, the second pressure block 5 is pulled so that the clamping end of the second pressure block 5 is away from the placement area of ​​the roller side plate 7. After the roller side plate 7 is placed, the second pressure block 5 is pushed so that the clamping end of the second pressure block 5 is above the roller side plate 7, and the second clamping nut is rotated to press the placed roller side plate 7 firmly.

[0021] Furthermore, the second pressure block 5 is equipped with a limiting block located at one end of the strip-shaped hole of the second pressure block 5, extending towards the base plate 1. The length of the limiting block extending towards the base plate 1 is less than the thickness of the roller side plate 7. Based on the clearance fit between the strip-shaped hole of the second pressure block 5 and the second connecting post, the second pressure block 5 may rotate before being tightened by the second clamping nut. By setting the limiting block, when the second pressure block 5 rotates to a certain angle, the limiting block is abutted by the edge of the installed roller side plate 7, ensuring that the end of the second pressure block 5 without the limiting block is always above the installed roller side plate 7, thus ensuring that the second clamping nut can drive the second pressure block 5 to tighten the roller side plate 7 when tightened.

[0022] Furthermore, to enable the simultaneous processing of two identical roller side plates 7, two auxiliary positioning blocks 6 are provided on the upper surface of the base plate 1. These two auxiliary positioning blocks 6 are symmetrically arranged on both sides of the working center line, and are located on the outer side between the two positioning blocks 2. This ensures symmetry in the placement areas of the roller side plates 7 on both sides of the working center line, creating an L-shaped placement area composed of positioning blocks 2 and auxiliary positioning blocks 6 on both sides, further improving installation efficiency. Correspondingly, the second compaction block 5 is also symmetrically arranged on both sides of the working center line.

[0023] Working Principle: Rotate the first clamping nut to release the clamping force on the first clamping block 4. Rotate the first clamping block 4 so that its extension direction is parallel to the working center line, thus releasing its obstruction of the roller side plate 7 placement area. Adjust the position of the second clamping block 5 to release its obstruction of the roller side plate 7 placement area. Place the two roller side plates 7, ensuring that the edges of both plates abut against the positioning block 2. With the auxiliary positioning block 6 present, ensure that the edges of both side plates abut against both the positioning block 2 and the auxiliary positioning block 6 simultaneously. Then rotate the first clamping block 4 so that both ends are above the two roller side plates 7. Rotate the first clamping nut to press the first clamping block 4 firmly against the two side plates 7. Adjust the second clamping block 5 to also press it firmly against the side plates 7, completing the simultaneous clamping of the two side plates 7.
