Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides the following technical solutions:

[0024] Embodiment 1

[0025] See also Figure 1-3 A sliding bearing assembly fixture comprises a U-shaped frame 1, a clamping assembly 2 is arranged at the left end of the U-shaped frame 1, and a fixing mechanism 3 is arranged at the left end of the inner wall of the U-shaped frame 1.

[0026] The fixing mechanism 3 includes a sliding groove 301, which is provided at the left end of the inner wall of the U-shaped frame 1. A slider 302 is slidably connected to the inner wall of the sliding groove 301. The right end of the slider 302 is fixedly connected to a limiting plate 303. A limiting groove 304 is provided at the upper end of the limiting plate 303. Springs 1 305 are provided at the front and rear ends of the limiting groove 304. Trapezoidal plates 306 are provided on the opposite surfaces of the two springs 1 305. By using the trapezoidal plates 306, springs 1 305, springs 2 309 and other parts, the bearing can be placed between the trapezoidal plates 306 after the limiting plate 303 is pulled out, so that the springs 1 305 fix the bearing. The springs 2 309 can make the limiting plate 303 return to its original position through the springs 2 309 after the bearing is placed, so that the subsequent clamping assembly 2 can clamp the bearing and improve the clamping efficiency.

[0027] Furthermore, the clamping assembly 2 includes a rotating hole 201, a threaded rod 202, a threaded block 203, a clamping arc plate 204, a fixed rod 205 and a friction particle plate 206. The rotating hole 201 is opened at the left end of the U-shaped frame 1, the threaded rod 202 is movably connected to the inner wall of the rotating hole 201 through a bearing, the threaded block 203 is threadedly connected to the outer wall of the threaded rod 202, and the lower end of the threaded block 203 is fixedly connected with the clamping arc plate 204. By using the clamping assembly 2, when the threaded rod 202 is rotated, the clamping arc plate 204 is contracted or separated under the limit of the fixed rod 205, so that it can be suitable for bearings of different sizes.

[0028] Furthermore, the fixing rod 205 is fixedly connected to the left and right ends of the inner wall of the U-shaped frame 1, the right end of the fixing rod 205 passes through the left end of the threaded block 203 and is movably connected to the left end of the threaded block 203, there are two clamping arc plates 204, and the friction particle plate 206 is fixedly connected to the opposite surfaces of the two clamping arc plates 204. By using its threaded block 203, the threaded block 203 can be moved synchronously by rotating the threaded rod 202 under the limit of the fixing rod 205, so as to facilitate subsequent clamping operations.

[0029] Furthermore, a T-slot 307 is provided at the lower end of the inner wall of the limiting groove 304, and a T-block 308 is slidably connected to the inner wall of the T-slot 307. The T-block 308 is fixedly connected to the lower end of the trapezoidal plate 306. By using the T-block 308, the T-slot 307 limits the T-block 308, thereby facilitating the movement of the trapezoidal plate 306.

[0030] Furthermore, the rear end of the slider 302 is fixedly connected to a spring 2 309, and the spring 2 309 is fixedly connected to the front end of the inner wall of the limiting groove 304. By using the spring 2 309, after the limiting plate 303 is pulled out through the handle 312, the restoring force of the spring 2 309 can cause the limiting plate 303 to move to its original position.

[0031] Embodiment 2

[0032] Combination Figure 1-4 On the basis of the first embodiment, the front end of the spring 1 305 is further fixedly connected with a connecting block 1 310, and the connecting block 1 310 is fixedly connected to the rear end of the inner wall of the limiting groove 304. By using the spring 1 305, when the bearing is placed, the spring 1 305 can be compressed to tighten the bearing.

[0033] Furthermore, the rear end of spring 1 305 is fixedly connected to connecting block 2 311, and connecting block 2 311 is fixedly connected to the front end of trapezoidal plate 306. The front end of limit plate 303 is fixedly connected to handle 312. By using handle 312, the limit plate 303 can be moved by pulling handle 312 during the clamping process of the bearing.

[0034] In actual operation, when this device is used, the limit plate 303 can be pulled out first, so that the slider 302 connected to the limit plate 303 pulls the spring 2 309, and then the bearing to be clamped is pressed through the trapezoidal plate 306, so that the spring 1 305 squeezes the trapezoidal plate 306, and then the limit plate 303 is inserted through the restoring force of the spring 2 309 to restore the limit plate 303 to its original position. Then, by twisting the threaded rod 202, the clamping arc plate 204 is retracted under the limiting action of the fixed rod 205, thereby completing the clamping work of the bearing.
