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

[0022] Reference Figure 1-5 A four-axis hydraulic clamp for a stop plate includes a large base plate 100. A four-axis cam turntable 101 and a disc-type brake tailstock 102 are arranged on the top side of the large base plate 100. A turntable L-plate 103 is arranged on the side of the four-axis cam turntable 101 and the disc-type brake tailstock 102 that are close to each other. A common mounting plate 104 is arranged on both turntable L-plates 103. Two fixed seats 200 are mounted on the mounting plate 104. Two sliding blocks 201 are slidably mounted on the top side of the fixed seats 200. V-shaped grippers 202 are fixedly installed on each block 201. Two contour positioning blocks 400 are also arranged on the fixed base 200. The stability of the clamping process is ensured by a four-axis hydraulic drive. The V-shaped grippers, anti-misalignment blocks, anti-misalignment positioning pins, and anti-reverse mounting blocks cooperate with each other to complete part of the fixation, while the contour positioning blocks, positioning pins, side positioning pins, and corner pressure plates cooperate with each other to complete the other part of the positioning, thereby achieving stable fixation of irregular parts with good fit and avoiding deformation of the stop plate under pressure.

[0023] In an optional embodiment: a positioning mounting plate 203 is arranged at the top of the fixed base 200, the positioning mounting plate 203 is located between two V-shaped grippers 202, and the positioning mounting plate 203 is provided with an anti-misalignment block 204, an anti-misalignment positioning pin 205, and an anti-reverse mounting block 206.

[0024] It should be noted that two fixed seats 200 are used on the mounting plate 104 to support part of the stop plate, and the positioning mounting plate 203, the anti-misalignment block 204, and the anti-misalignment positioning pin 205 cooperate with each other to initially restrict the movement of the stop plate.

[0025] In an optional embodiment: a hydraulic cylinder 300 is arranged on the mounting plate 104, and two rotating shafts 301 are arranged on the fixed base 200. An L-shaped drive rod 302 is rotatably mounted on each of the two rotating shafts 301. The bottom end of the L-shaped drive rod 302 is in contact with the output end of the hydraulic cylinder 300, and the top end of the L-shaped drive rod 302 is in contact with the corresponding sliding block 201.

[0026] It should be noted that the output end of the hydraulic cylinder 300 drives the L-shaped drive rod 302 to rotate on the rotating shaft 301. One end of the rotating shaft 301 will cause the sliding block 201 to slide on the fixed seat 200, thereby driving the V-shaped gripper 202 to move through the sliding block 201, so that the two V-shaped grippers 202 move closer to each other and fix the position of the stop plate.

[0027] In an optional embodiment: the contour positioning block 400 is provided with a positioning pin 401 and a side positioning post 402, and the disc brake tailstock 102 is provided with a connector 403.

[0028] In an optional embodiment: a lifting hydraulic rod 404 and a rectangular plate 405 are fixedly installed on the mounting plate 104, a lifting rod 406 is slidably installed on the rectangular plate 405, a corner pressure plate 407 is fixedly installed at the top of the lifting rod 406, and the bottom end of the lifting rod 406 is connected to the output end of the lifting hydraulic rod 404.

[0029] It should be noted that in another part of the disc brake tailstock 102, the contour positioning block 400, positioning pin 401, and side positioning post 402 cooperate to initially fix the other end of the stop plate. The lifting hydraulic rod 404 is activated, and the output end of the lifting hydraulic rod 404 drives the lifting rod 406 to rise and fall, thereby driving the corner pressure plate 407 to lock the stop plate on the contour positioning block 400, positioning pin 401, and side positioning post 402, so as to achieve stable fixation.

[0030] In an optional embodiment, four lifting rings 105 are fixedly mounted on the mounting plate 104.

[0031] It should be noted that the mounting plate 104 is moved using four lifting rings 105.

[0032] In an optional embodiment: a clamping plate 106 is fixedly installed on the side of the four-axis cam turntable 101, and an oil circuit distributor 107 is fixedly installed on the clamping plate 106, with one end of the oil circuit distributor 107 extending into the four-axis cam turntable 101.

[0033] Working principle of this utility model:

[0034] When using this device, the cage disc brake tailstock 102 and the four-axis cam turntable 101 cooperate to fix the positions of the turntable L-plate 103 and the mounting plate 104. The mounting plate 104 can be removed from the device using the lifting ring 105, facilitating the installation and removal of the stop plate. Two fixed seats 200 support a portion of the stop plate on the mounting plate 104. The positioning mounting plate 203, anti-misalignment block 204, and anti-misalignment positioning pin 205 cooperate to initially restrict the movement of the stop plate. Simultaneously, the hydraulic cylinder 300 is activated. The output end of the hydraulic cylinder 300 drives the L-shaped drive rod 302 to rotate on the rotating shaft 301. The rotating shaft 301 rotates... The end will cause the sliding block 201 to slide on the fixed seat 200, thereby driving the V-shaped gripper 202 to move through the sliding block 201, so that the two V-shaped grippers 202 move closer to each other and fix the position of the stop plate. In the other part of the disc brake tail seat 102, the contour positioning block 400, positioning pin 401, and side positioning column 402 cooperate to initially fix the other end of the stop plate. The lifting hydraulic rod 404 is activated, and the output end of the lifting hydraulic rod 404 drives the lifting rod 406 to rise and fall, thereby driving the corner pressure plate 407 to clamp the stop plate on the contour positioning block 400, positioning pin 401, and side positioning column 402, achieving stable fixation.

[0035] 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.
