[0021] In order to make the purpose, features, and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the embodiments described below are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0022] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 , a kind of automobile bearing disassembly device, comprises a bearing body 1 and a base 2, the bearing body 1 is arranged inside the base 2, an inner sleeve 4 is inserted in the middle of the bearing body 1, an outer sleeve 3 is arranged above the inner sleeve 4, the inner sleeve 4 is slidably sleeved inside the outer sleeve 3, the top surface of the inner sleeve 4 is rotatably connected with a first screw 5, the first screw 5 is threadedly connected to the top surface of the outer sleeve 3, a first control knob 6 is fixed to the top surface of the first screw 5, two support plates 7 are symmetrically fixed at the lower outer side of the outer sleeve 3, each support plate 7 is threadedly sleeved with a second screw 8, a second control knob 9 is fixed at the top of the second screw 8, a bottom plate 10 is fixed at the bottom end of the second screw 8, two limit rings 14 are slidably connected to the bottom end of the outer side of the inner sleeve 4, a third control knob 11 is arranged at the bottom end of the inner sleeve 4, the third control knob 11 controls the movement of the limit ring 14, so that the bearing body 1 is more convenient to take out through the inner sleeve 4.

[0023] Specifically, a tool groove is provided on the top surface of the first control knob 6, and a rubber pad is provided on the bottom surface of the base plate 10, so that the staff can remove the bearing body 1 more conveniently and labor-savingly. The outer ring radius of the inner sleeve 4 is smaller than the inner ring radius of the bearing body 1, and the width of the first screw 5 is smaller than the width between the two farthest cylinders on the top surface of the bearing body 1, so as to prevent the bearing body 1 from blocking the first screw 5.

[0024] As an optimization solution, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a gear 12 is fixed on the top of the third control knob 11, and the gear 12 is rotatably connected to the inside of the inner sleeve 4. Two sliding rods 13 are meshed and linked on both sides of the gear 12. The sliding rod 13 is slidably connected to the inside of the inner sleeve 4, and one end of the sliding rod 13 is fixedly connected to the limit ring 14, so that the third control knob 11 can more flexibly control the limit ring 14.

[0025] Specifically, the opposite ends of the two sliding rods 13 are fixedly connected to the two limit rings 14 respectively, and the outer sides of the limit rings 14 are located in the same plane as the outer sides of the inner sleeve 4, so that the two limit rings 14 move simultaneously. The side of the limit ring 14 close to the third control knob 11 is fixedly connected to the limit rod 15, and a sliding groove matching the shape of the limit rod 15 is opened inside the inner sleeve 4 to prevent the limit ring 14 from slipping out of the inner sleeve 4.

[0026] Working principle: When the bearing body 1 needs to be taken out from the base 2, the first control knob 6 is turned, so that the first control knob 6 drives the first screw 5 to rotate, and the first screw 5 moves downward at the same time, so that the first screw 5 drives the inner sleeve 4 to move downward, and the inner sleeve 4 passes through the middle of the bearing body 1, and the third control knob 11 is turned, so that the third control knob 11 drives the gear 12 to rotate, and the gear 12 drives the slide bar 13 to move while rotating, so that the slide bars 13 on both sides respectively drive the limit rings 14 to move outward, and the limit rings 14 are moved to the opposite sides according to the thickness of the bearing body 1. After reaching the corresponding distance, turn the second control knob 9 so that the second control knob 9 drives the second screw 8 to rotate, so that the second screw 8 moves downward while moving inside the support plate 7, and at the same time, the second screw 8 drives the bottom plate 10 to move downward. When the bottom plate 10 contacts the top surface of the base 2, use the tool to reversely rotate the first control knob 6 so that the first control knob 6 drives the first screw 5 to rotate in the opposite direction, so that the first screw 5 drives the inner sleeve 4 to move upward. At this time, the limit ring 14 is forced to contact the bottom surface of the bearing body 1, so that the limit ring 14 takes the bearing body 1 out of the base 2.
