[0021] 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.

[0022] The following is in conjunction with the appendix Figure 1-2This application provides a further detailed description. An embodiment of this application discloses a clamping fixture for the rear frame of a road roller. The working surface of the base 1 is provided with four positioning blocks 2, which form a quadrilateral processing area to accommodate the road roller rear frame 6 to be processed. Positioning blocks 2 are provided at positions corresponding to the four sides of the quadrilateral processing area, resulting in at least four positioning blocks 2. The positions of the positioning blocks 2 also determine the range of the processing area and the specific position where the road roller rear frame 6 is placed in the base 1. The working surface of the base 1 is provided with a movable pressing block 3, which moves linearly back and forth towards the processing area. When the movable pressing block 3 extends into the processing area, it presses down on the road roller rear frame to be processed. When the movable pressing block 3 leaves the processing area, it contacts the obstruction to the movement space, thereby allowing the road roller rear frame to be placed or removed. The base 1 is detachably connected to a fixing block 4, which is located within the processing area. When it is necessary to press the rear frame of the road roller, the fixing block 4 is connected and pressed; when it is not necessary to press the rear frame, the fixing block 4 is removed. The working surface of the base 1 is also equipped with a clamping moving rod 5, which is located outside the processing area. The clamping moving rod 5 moves linearly back and forth towards the processing area, pressing against the rear frame of the road roller located within the processing area. This, in conjunction with the positioning block 2, achieves the effect of clamping the rear frame of the road roller.

[0023] Furthermore, the positioning block 2 has a positioning block connecting hole, and the base 1 has a positioning connecting hole corresponding to the positioning block connecting hole. The positioning block connecting holes and the positioning connecting holes are connected by bolts. The number of positioning connecting holes corresponds to the number of positioning block connecting holes and they are grouped together. The number of positioning connecting holes is determined by the number of positioning block connecting holes; when there is only one positioning block connecting hole, there is also only one positioning connecting hole, and each hole forms a group. For example... Figure 1-2 In the illustrated embodiment, the positioning block has four connecting holes, and these connecting holes are also grouped in sets of four. Each positioning block 2 has one or more sets of connecting holes, with at least one set used for connection with the positioning block 2. When two or more sets of connecting holes are provided, the position of the positioning block 2 relative to the base 1 can be changed to accommodate different specifications of road roller rear frame models. Two or more positioning blocks 2 can also be connected simultaneously to enhance the positioning effect of the positioning block 2 and the clamping effect in conjunction with the clamping moving rod 5.

[0024] Furthermore, a movable pressure block connecting rod is connected to the working surface of the base 1, and the extension direction of the movable pressure block connecting rod is perpendicular to the working surface of the base 1. The movable pressure block 3 has a strip-shaped hole, which is clearance-fitted with the movable pressure block connecting rod, allowing the movable pressure block 3 to move linearly and reciprocally. A movable pressure block nut is connected to the movable pressure block connecting rod, located on the side of the movable pressure block 3 away from the base 1. The movable pressure block 3 moves axially along the movable pressure block connecting rod. Moving the movable pressure block 3 axially towards the base 1 achieves a pressing effect, while moving it axially away from the base 1 achieves a lifting effect.

[0025] Furthermore, to prevent the movable pressure block 3 with the strip-shaped hole from rotating around the movable pressure block connecting rod during pressing or lifting, a limiting rod is provided at the end of the movable pressure block 3 away from the processing area. The base 1 has a limiting rod hole, and the limiting rod is clearance-fitted with the limiting rod hole to restrict the rotation of the movable pressure block 3.

[0026] Furthermore, the base 1 is connected to a fixed pressure block connecting rod, the extension direction of which is perpendicular to the working surface of the base 1. The fixed pressure block 4 has a fixed pressure block connecting hole, and the fixed pressure block connecting rod is clearance-fitted into this hole. A fixed pressure block nut is connected to the fixed pressure block connecting rod, located on the side of the fixed pressure block 4 furthest from the base 1. When the rear frame of the road roller is installed into the processing area, the fixed pressure block connecting rod extends into the rear frame of the road roller, and then the fixed pressure block connecting hole of the fixed pressure block 4 is fitted into the fixed pressure block connecting rod. The fixed pressure block 4 is then moved axially along the fixed pressure block connecting rod by the fixed pressure block nut, achieving the effect of pressing down and lifting the fixed pressure block 4 relative to the base 1.

[0027] Furthermore, in order to improve the efficiency of installing the fixing block 4 into the fixing block connecting rod, the fixing block 4 has a notch on its side along the extension direction of the fixing block 4. The notch communicates with the fixing block connecting hole, and the width of the notch is greater than the diameter of the fixing block connecting rod, so that the fixing block 4 can be inserted into the fixing block connecting rod from the side, without having to be inserted from the end of the fixing block 4 connecting rod, which significantly improves the efficiency of installing and removing the fixing block 4 and the fixing block connecting rod.

[0028] Furthermore, the working surface of the base 1 is connected to a pad, which is located in the processing area and is used to provide support for the part of the road roller rear frame that is installed in the processing area and contacts the base 1.

[0029] Furthermore, the movement drive of the clamping moving rod 5 can adopt conventional technical means such as cylinders or hydraulic cylinders. In this embodiment, the working surface of the base 1 is provided with a moving seat, the moving seat has a threaded hole, the clamping moving rod 5 is a threaded rod, the threaded rod is threadedly connected to the moving seat, and by rotating the clamping moving rod 5, the position of the clamping moving rod 5 relative to the moving seat is changed, thereby achieving a linear reciprocating movement effect.

[0030] Furthermore, the movable seat is set on the positioning block 2, saving on the structural layout of the working surface of the base 1.

[0031] Working principle: Remove the fixed pressure block 4, move the movable pressure block 3 away from the processing area, and control the clamping moving rod 5 away from the processing area. Place the rear frame of the road roller to be processed into the processing area according to the position of the positioning block 2. Move the movable pressure block 3 into the processing area and control it to press down towards the base 1 to fix the rear frame of the road roller. Install the fixed pressure block 4 and control it to press down further to fix the rear frame of the road roller. Finally, control the clamping moving rod 5 to move towards the processing area and abut against the rear frame of the road roller within the processing area. With the cooperation of the clamping moving rod 5 and the positioning block 2, the rear frame of the road roller is clamped, thus fixing the rear frame of the road roller to the working surface of the base 1.
