Two second fixing mechanisms 5 are symmetrically distributed on the left and right sides of the upper side of the first fixing mechanism 4.

[0025] It should be noted that the rubber pad 3 is used to reduce the vibration generated when the internal motor is running, so as to avoid the vibration from causing the whole self-moving.

[0026] As shown in Figure 2 , Figure 3 , the first fixing mechanism 4 comprises a first motor 41, the lower side of the first motor 41 is fixedly connected to the left side middle part of the inner side lower surface of the machine table 1, the left and right sides middle parts of the inner side of the machine table 1 are rotatably connected with a first lead screw 42, the outer side of the first lead screw 42 is close to the left side, and the output end of the first motor 41 is fixedly connected with a gear 43, the two gears 43 are meshingly connected together on the side close to each other, and the outer side of the first lead screw 42 is threadedly connected with two moving tables 46 which are symmetrically distributed.

[0027] It should be noted that the first motor 41 drives the gear 43 located at the rear side to rotate, thereby making the gear 43 at the front side rotate, and further making the first lead screw 42 rotate. The first lead screw 42 is a bidirectional lead screw, which contains two threads in opposite directions. The two moving tables 46 are threadedly connected with threads in different directions, respectively. When the first lead screw 42 rotates, the two moving tables 46 move in opposite directions in the left-right direction.

[0028] As shown in Figure 5 , the upper surface of the middle part of the side close to each other of the two moving tables 46 is fixedly connected with a threaded seat 44, and the inner side of the two threaded seats 44 is threadedly connected with a fixed insertion rod 45.

[0029] It should be noted that the diameter of the fixed insertion rod 45 can be configured according to the mounting hole at the bottom of the bearing seat clamped. The fixed insertion rod 45 is inserted into the mounting hole, and then the moving table 46 moves a small distance in the opposite direction, so that the fixed insertion rod 45 fixes the bearing seat. The threaded seat 44 can quickly replace the fixed insertion rod 45 with different diameters to adapt to bearing seats of different sizes.

[0030] As shown in Figure 4 , Figure 5 , the second fixing mechanism 5 comprises a second lead screw 52, the outer wall of the second fixing mechanism 5 close to the front and rear ends is rotatably connected to the upper side of the inner part of the moving table 46, the front side of the moving table 46 close to the bottom is fixedly connected with a second motor 51, the outer wall of the second lead screw 52 close to the front end and the output end of the second motor 51 are fixedly connected with a sprocket 53, the side surface of the sprocket 53 is meshingly connected with a chain 54, and the outer side of the second lead screw 52 is threadedly connected with two moving plates 55 which are symmetrically distributed in front and back, and the lower side of the moving plate 55 is movably sleeved on the outer side of the moving table 46.

The outer sides of the plurality of limiting rods 56 are movably sleeved with springs 58, and the springs 58 are located on the side of the moving plate 55 close to the clamping table 57.

[0033] It should be noted that when the moving plates 55 are close to each other, the clamping tables 57 are driven to be close to each other, so that the clamping tables 57 clamp the front and back sides of the bearing seat bottom mounting plate. The spring 58 is arranged to avoid the direct rigid contact of the clamping table 57 with the bearing seat, which causes the deformation of the clamping table 57 or the bearing seat.
