Detailed implementation manners

[0025] The present utility model will be further described below in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it, but the embodiments cited do not limit the present utility model.

[0026] Refer to Figure 1 - Figure 6 As shown, a high-precision inner wall polishing device for a bearing seat of the present utility model includes a support frame 11 and a bearing limit platform 12 detachably installed on the outer surface of the top end of the support frame 11, a first fixing plate 13 fixedly installed on the outer surface of the top of the bearing limit platform 12, a lifter 14 fixedly installed at the center position of the top of the first fixing plate 13, a bearing 15 movably sleeved on the outer surface of the bearing limit platform 12, a puller 131 arranged on the outer surface of the first fixing plate 13, and a U-shaped limit plate 133 arranged at the output end of the puller 131; a placement groove 121 is opened on the outer surface of the top of the bearing limit platform 12, a blanking chute hole 122 penetrating the surface of the bearing limit platform 12 is opened on the inner wall surface of the placement groove 121, and a support tube 115 is movably sleeved on the inner wall surface of the blanking chute hole 122.

[0027] Refer to Figure 1 - Figure 6As shown, in an embodiment of the present utility model, the bearing 15 is placed inside the blanking chute hole 122. At the same time, the position of the bearing 15 is limited by the support pipe 115 on the inner side wall surface of the blanking chute hole 122. Meanwhile, the U-shaped limiting plate 133 is pulled by the pulling rope 132 at one end of the puller 131. The surface of the bearing 15 is squeezed and pulled by the U-shaped limiting plate 133. At the same time, due to the height difference between the support pipe 115 and the entrance of the blanking chute hole 122, the surface of the bearing 15 will fit against the inner side wall surface of the blanking chute hole 122. Under the pulling of the U-shaped limiting plate 133, the surface of the bearing 15 will be squeezed and fit against the inner side wall surface of the blanking chute hole 122, thereby limiting the position of the bearing 15. By using the staggered height difference and under the pulling of the U-shaped limiting plate 133, the bearing 15 is made to fit against the inner surface of the blanking chute hole 122 to limit the position of the bearing 15, avoiding the situation in the traditional installation of bearings where a single bearing needs to be fixed with screws or clamping blocks, and it is impossible to clamp and install multiple bearing rings simultaneously, and single fixing will waste a lot of time.

[0028] Referring to Figure 1 - Figure 6 As shown, in an embodiment of the present utility model, a second fixing plate 141 is fixedly connected to the bottom surface of the lifter 14. A support arm 142 is fixedly connected to the output end of the second fixing plate 141. A motor 143 is fixedly installed at one end of the support arm 142.

A blower 146 is fixedly installed on the top surface of the second fixing plate 141 and at the four peripheral edge positions of the lifter 14. An air guide hose 147 is fixedly connected to the output end of the blower 146 and is arranged on the outer surface of the support arm 142. One end of the air guide hose 147 is fixedly connected to an air suction pipe 145 that is movably lapped on the outer surface of the motor 143. A lapping collar 111 is fixedly connected to the top end of the support frame 11 and is arranged on the outer surface of the bearing limiting platform 12. A support plate 112 is fixedly connected to the middle position on the outer side of the lapping collar 111. A cushion plate 113 is fixedly installed at the middle position on the top of the support plate 112. The bottom end of the support pipe 115 is fixedly connected to the top surface of the cushion plate 113. A hydraulic mortar rod 114 is fixedly installed at the middle position on the top surface of the cushion plate 113, and the output end of the hydraulic mortar rod 114 is fixedly connected to the bottom surface of the bearing limiting platform 12. A pulling rope 132 is fixedly connected to the output end of the puller 131, and one end of the pulling rope 132 is fixedly connected to the outer surface of the U-shaped limiting plate 133.

[0029] After the position of the bearing 15 is limited by the U-shaped limiting plate 133, the lifter 14 is used to lower the support arm 142, so that the polishing drill bit 144 at one end of the support arm 142 extends into the inner wall surface of the bearing 15. While the motor 143 rotates the polishing drill bit 144, the inner wall surface of the bearing 15 is polished. At the same time, the blower 146 is used to extract air from the inside of the air guide hose 147 and the suction pipe 145, so as to achieve the effect of recycling and cleaning the debris and burrs polished by the polishing drill bit 144;

[0030] When the bearing 15 is polished, after the U-shaped limiting plate 133 is loosened, the hydraulic mortar rod 114 is used to lower the bearing limiting table 12, so that the surface of the bearing limiting table 12 is separated from the top surface of the support pipe 115. Under the limitation of the inner wall surface of the blanking chute hole 122, the bearing 15 will be vertically lapped on the top surface of the support pipe 115. Then, the employee replaces the bearing 15 on the top surface of the support pipe 115 and replaces it with a new bearing 15. Then, the hydraulic mortar rod 114 is used to lift the bearing limiting table 12. Under the limitation of the internal position of the blanking chute hole 122, the inner wall surface of the blanking chute hole 122 will adjust the position of the bearing 15.

[0031] Working principle: The bearing 15 is placed into the inside of the blanking chute hole 122. At the same time, the position of the bearing 15 is limited by the support pipe 115 on the inner wall surface of the blanking chute hole 122.

At the same time, taking advantage of the height difference between the support pipe 115 and the entrance of the blanking chute hole 122, the surface of the bearing 15 will fit on the inner wall surface of the blanking chute hole 122. Under the pull of the U-shaped limiting plate 133, the surface of the bearing 15 will be squeezed and fit on the inner wall surface of the blanking chute hole 122, so as to limit the position of the bearing 15. By using the staggered height difference and under the pull of the U-shaped limiting plate 133, the bearing 15 is made to fit on the inner surface of the blanking chute hole 122 to limit the position of the bearing 15;

[0032] After the position of the bearing 15 is limited by the U-shaped limiting plate 133, the lifter 14 is used to lower the support arm 142, so that the polishing drill bit 144 at one end of the support arm 142 extends into the inner wall surface of the bearing 15. While the motor 143 rotates the polishing drill bit 144, the inner wall surface of the bearing 15 is polished. At the same time, the blower 146 is used to extract air from the inside of the air guide hose 147 and the suction pipe 145, so as to achieve the effect of recycling and cleaning the debris and burrs polished by the polishing drill bit 144;

[0033] After the bearing 15 is polished, loosen the U-shaped limit plate 133, and cooperate with the hydraulic mortar rod 114 to lower the bearing limit table 12, so that the surface of the bearing limit table 12 is separated from the top surface of the support pipe 115. Under the limitation of the inner wall surface of the blanking groove hole 122, the bearing 15 will be vertically lapped on the top surface of the support pipe 115. Then, the employee replaces the bearing 15 on the top surface of the support pipe 115 and replaces it with a new bearing 15. Then, the hydraulic mortar rod 114 is used to lift the bearing limit table 12. Under the limitation of the internal position of the blanking groove hole 122, the inner wall surface of the blanking groove hole 122 will adjust the position of the bearing 15.
