[0021] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will detail this application with reference to the drawings and in conjunction with the embodiments. Embodiment

[0022] See Figures 1 - 4 , this embodiment provides a lateral fixed finishing fixture, including a base 1. A fixing device 2 is arranged on the base 1. The fixing device 2 includes a fixing seat 21. A slider 22 is slidably connected to the outer wall of the fixing seat 21. The top of the slider 22 is fixedly connected to a support rod 25, and the top of the support rod 25 is fixedly connected to a clamping block 26. A moving rod 24 is hinged to the front of the slider 22. A first chute 27 is opened on the front of the moving rod 24, and a second chute 28 is opened on the front of the moving rod 24. A first fixing rod 29 is fixedly connected to the front of the slider 22. The bottom of the inner wall of the base 1 is fixedly connected to a first hydraulic cylinder 211. The top of the output end of the first hydraulic cylinder 211 is fixedly connected to a connecting block 212. A second fixing rod 210 is fixedly connected to the front of the connecting block 212. A groove 23 is opened on the top of the base 1. The first chute 27 is slidably connected to the outer wall of the first fixing rod 29, and the second chute 28 is slidably connected to the outer wall of the second fixing rod 210. A bracket 4 is fixedly connected to the top of the base 1. The bracket 4 is cast in an integrated manner, which improves the integrity. There is no interface inside, and there is no weakness problem at the interface. It does not need to be assembled and can be directly installed, which is convenient for production, manufacturing and maintenance. It reduces the number of parts and steps in the assembly process, reduces the assembly cost and time, reduces the connection points and joints, reduces the risk of loosening or failure between parts, enhances the structural strength and stability of the overall component, and improves the long-term service life of the product.

[0023] When the above-mentioned device is in specific use, by placing the workpiece on the top of the bracket 4 and the middle of the clamping block 26, the first hydraulic cylinder 211 is started. The first hydraulic cylinder 211 drives the output end to move downward, and the output end drives the connecting block 212 to move downward. The second fixed rod 210 at the top of the connecting block 212 drives the second chute 28 on the front of the moving rod 24 to move to the right. The first chute 27 opened on the front of the moving rod 24 drives the first fixed rod 29 on the front of the slider 22 to move to the left. The first fixed rod 29 drives the slider 22 and the clamping block 26 to move to the left. The slider 22 drives the clamping block 26 to clamp the workpiece, improving the stability during the processing of the workpiece. Through the action of the first hydraulic cylinder 211, the connecting block 212 and the first fixed rod 29 can accurately adjust their positions, so as to ensure that the workpiece remains stable under the fixation of the clamping block 26 and is not prone to movement, thus solving the problem of unstable or ineffective clamping force in the background technology, which affects the processing accuracy.

The bottom of the inner wall of the chute is rotatably connected to a rotating rod 33 through a bearing. A circular gear 34 is fixedly sleeved on the outer wall of the rotating rod 33. A support plate 35 is fixedly connected to the front of the bracket 4. A second hydraulic cylinder 36 is fixedly connected to the front of the support plate 35.

[0025] When the above-mentioned device is in specific use, starting the second hydraulic cylinder 36 drives the sliding plate 31 to move forward. The sliding plate 31 drives the rack 32 to move backward. The rack 32 drives the circular gear 34 to rotate. The rotation of the circular gear 34 drives the rack 32 on the left side to move forward. The two racks 32 move relative to each other, and the two racks 32 drive the sliding plate 31 to move relative to each other.
