DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments 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. Example

[0018] The present application relates to a grinding device for a thrust block 20, such as Figure 1-10 As shown, the grinding device includes a frame 3 for serving as a basic support, a pot body 5 which is recessed downward to serve as a grinding container is arranged at the center of the top of the frame 3, and a grinding assembly 6 which can grind the thrust block 20 is arranged inside the pot body 5. In order to increase the number of thrust blocks 20 that can be grinded at the same time, a plurality of clamps 4 for clamping the thrust blocks 20 are arranged on the upper part of the grinding assembly 6, and a supporting assembly 2 which supports and positions the clamps 4 is added on the upper part of the frame 3. In order to avoid smoke or heat accumulation due to dry friction between the grinding assembly 6 and the thrust block 20, a spray assembly 1 which can spray coolant is also added on the upper part of the frame 3.

[0019] The grinding assembly 6 includes a grindstone 7, a shaft 9, and a motor 8. The grindstone 7 is suspended inside the pot body 5 for contacting the thrust block 20. The shaft 9 passes through the pot body 5 and is connected to the grindstone 7. A shaft sealing structure is arranged between the shaft 9 and the pot body 5. The lower end of the shaft 9 is connected to the frame 3 through a bearing seat, and a motor 8 for driving the shaft 9 to rotate is arranged on the upper part of the frame 3, so that the motor 8 drives the grindstone 7 inside the pot body 5 to rotate through the shaft 9, so that dynamic friction is formed between the grindstone 7 and the thrust block 20, and then the grinding operation of the thrust block 20 is completed with the help of friction.

[0020] The supporting assembly 2 includes a support rod and a roller sleeve 12. The support rod is fixedly arranged on the upper part of the frame 3 and extends in the horizontal direction of the pot body 5. The support rod is divided into a main rod 10 and a secondary rod 11. The main rod 10 is arranged toward the axis of the grinding stone 7, and the secondary rod 11 is vertically arranged on one side of the main rod 10. The ends of the main rod 10 and the secondary rod 11 are both provided with a roller sleeve 12 that can rotate freely. The roller sleeve 12 is used to abut against the clamp 4, so that when the grinding stone 7 rolls, the collision and friction between the clamp 4 and the support rod are avoided. In order to effectively support the clamp 4, the length ratio between the main rod 10 and the secondary rod 11 is 2 to 4:1.

[0021] The spray assembly 1 includes a bucket body 13, a bracket 14 and a spray head 15. The bucket body 13 is arranged on one side of the upper part of the frame 3. The upper part of the frame 3 is provided with a bracket 14 for supporting the bucket body 13. One end of the bucket body 13 is provided with a spray head 15 connected thereto through a hose. The spray head 15 is arranged on the upper part of one of the main rods 10 for spraying coolant onto the surface of the grindstone 7 to reduce the frictional heat between the grindstone 7 and the thrust block 20 and avoid the thrust block 20 from being deformed due to heat.

[0022] The fixture 4 includes a chuck 19, a pressure plate 18, a sleeve 17 and a counterweight 16. The chuck 19 is keyed to the bottom of the pressure plate 18 for clamping the thrust block 20. The sleeve 17 is sleeved on the outer side of the pressure plate 18 for abutting against the roller sleeve 12. The counterweight 16 is detachably connected to the top of the pressure plate 18 for increasing the downward pressure so that the thrust block 20 can fully abut against the grindstone 7. A plurality of slots for placing the positioning columns 21 of the thrust block 20 are arranged at the lower end of the chuck 19. The slots and the positioning columns 21 are arranged with non-equal diameters so that the positioning columns 21 can move inside the slots to avoid the thrust block 20 from being unable to be installed into the slots due to processing errors.

[0023] Based on CN211117133U, the thrust block 20 is a fan-shaped structure, and a positioning column 21 and a supporting protrusion 22 are provided at the bottom of the thrust block 20, and a positioning hole is provided on the upper end face of the corresponding bearing seat. When the thrust block 20 is set on the bearing seat, the positioning column 21 is located in the positioning hole, and the supporting protrusion 22 is against the upper end face of the bearing seat; the positioning column 21 is used to limit the longitudinal movement of the thrust block 20 in the bearing seat, and the supporting protrusion 22 is used to support the thrust block 20 and can also realize a certain range of swing of the thrust block 20.

[0024] The positioning column 21 is a cylinder and is arranged perpendicular to the lower end surface of the thrust block 20; the positioning hole is a cylindrical blind hole, and the setting direction is the same as the axial direction of the bearing seat; the diameter of the positioning column 21 is smaller than the diameter of the positioning hole, so that the positioning column 21 can achieve a lower amplitude of swing in the positioning hole, thereby ensuring the swing of the thrust block 20 on the bearing seat. Specifically, the diameter difference between the positioning column 21 and the positioning hole can be 2 mm to 3 mm.

[0025] The support protrusion 22 is a curved protrusion, that is, one end of the support protrusion 22 away from the thrust block 20 is a curved surface, and the curved surface can ensure the swing of the thrust block 20 in all directions. The support protrusion 22 can be a hemispherical protrusion.

[0026] The positioning posts 21 and the supporting protrusions 22 may be arranged in such a manner that two positioning posts 21 are symmetrically arranged on the thrust block 20 and are arranged close to two side edges of the thrust block 20 , and the supporting protrusions 22 are arranged in the middle of the two positioning posts 21 .

[0027] When in use, the chuck 19 is connected to the pressure plate 18, and then the thrust block 20 is placed at the bottom of the chuck 19, and then the counterweight 16 is placed on the top of the pressure plate 18, and the sleeve 17 is connected to the pressure plate 18, and then the pressure plate 18 with the thrust block 20 can be placed on the upper part of the grindstone 7, and then the motor 8 is started to drive the grindstone 7 to rotate with the help of the shaft 9. At this time, the support rod uses the roller sleeve 12 at the end of its main rod 10 and the auxiliary rod 11 to abut against the sleeve 17 to prevent the clamp 4 from rotating with the grindstone 7. In this way, dynamic friction is formed between the thrust block 20 at the bottom of the clamp 4 and the grindstone 7, and as As the grindstone 7 continues to rotate, the lower surface of the thrust block 20 will be ground and polished. At the same time, by injecting coolant along the bucket 13 and then flowing to the surface of the grindstone 7 along the nozzle 15, the heat generated by the friction between the grindstone 7 and the thrust block 20 is reduced, so that the thrust block 20 can avoid high-temperature deformation, and the grindstone 7 will not crack due to high temperature. Since the coolant flows into the inside of the basin, in order to facilitate the recovery of the coolant and the cleaning operation of the grindstone 7, a drain port can be added to the lower part of the basin, and a convenient opening and closing operation can be achieved through a cap or a valve body.
