DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] like Figure 1-Figure 3As shown, a bearing ring processing device comprises a rotating table 1 and a mounting frame 2, the mounting frame 2 is arranged around the outer periphery of the rotating table 1, the rotating table 1 comprises a support seat 6 and a rotating disk 8 rotatably arranged on the support seat 6, a driving mechanism is arranged inside the support seat 6, the driving mechanism is a driving motor 7, the driving motor 7 can drive the rotating disk 8 to rotate counterclockwise on the support seat 6, a plurality of supporting arms 10 are arranged at the lower part of the rotating disk 8, a rotating seat 21 is rotatably arranged at one end of the supporting arm 10 close to the outer periphery of the rotating disk 8, a cylinder 22 is arranged inside the rotating seat 21, and a clamping block 3 is connected to the upper end of the piston rod of the cylinder 22. The driving motor 7 drives the rotating disk 8 to rotate, and the rotating disk 8 drives the supporting arm 10 to rotate, thereby driving the clamping block 3 to rotate inside the mounting frame 2. The bearing ring is mounted on the clamping block 3, and when the clamping block 3 rotates inside the mounting frame 2, the outer wall of the bearing ring can contact with the grinding strip 13, so that the outer wall of the bearing ring is polished by the grinding strip 13.

[0028] like Figure 4 As shown, the lower end of the cylinder 22 is connected to a driving gear 11, and a grinding strip 13 is provided on the side of the mounting frame 2 close to the rotating table 1. The height of the grinding strip 13 matches the height of the rotating seat 21. A rack 16 is provided on the side of the mounting frame 2 close to the rotating table 1, and the driving gear 11 can mesh with the rack 16. When the support arm 10 rotates to the inner side of the mounting frame 2, the driving gear 11 rotates under the action of the rack 16, thereby driving the coaxial clamping block 3 to rotate, and then driving the bearing ring on the clamping block 3 to rotate around its own axis. The direction of rotation of the bearing ring is opposite to the direction of rotation of the rotating disk 8, so that the friction between the outer wall of the bearing ring and the grinding strip 13 is increased, thereby obtaining a better grinding effect.

[0029] like Figure 5 As shown, a support frame 9 is installed at the lower part of the rotating disk 8, a support arm 10 is slidably arranged on the support frame 9, a rotating frame 19 is connected to one end of the support arm 10 away from the rotating seat 21, a rotating wheel 20 is rotatably arranged in the rotating frame 19, a mounting block 18 is connected to the side of the support arm 10, the mounting block 18 is located between the support frame 9 and the clamping block 3, a spring 26 is connected between the mounting block 18 and the support frame 9, a guide ring 12 is connected to the outer periphery of the support seat 6, and the rotating wheel 20 abuts against the guide ring 12. Under the action of the spring 26, the support arm 10 has a tendency to move to one side of the support seat 6, so that the rotating wheel 20 abuts against the outer periphery of the guide ring 12.

[0030] The present application further comprises a feeding mechanism 4 and a discharging mechanism 5 , one end of the feeding mechanism 4 and the discharging mechanism 5 extending above the rotating disk 8 .

[0031] like Figure 6 , Figure 7As shown, the feeding mechanism 4 includes a feeding plate 30, and the front and rear sides of the feeding plate 30 are both provided with a rib 31, a stopper 32 is provided at the end of the feeding plate 30 close to the rotating disk 8, an opening 33 is provided at the part of the feeding plate 30 located above the rotating disk 8, the opening 33 is connected to the front side surface of the feeding plate 30, an outlet 34 is provided at a position corresponding to the opening 33 on the rib 31 on the front side, and a top plate 35 is provided at a position above the feeding plate 30 corresponding to the opening 33.

[0032] The bearing ring moves in the feed plate 30 and is blocked by the block 32. As the support arm 10 rotates, the block 3 reaches the bottom of the feed mechanism 4, and the cylinder 22 drives the block 3 to rise, so that the upper end of the block 3 passes through the opening 33. The upper end of the block 3 extends into the bearing ring located above the opening 33. The block 3 is blocked by the top plate 35 to prevent the block 3 from driving the bearing ring to rise, so that the block 3 can be inserted into the bearing ring to complete the fixation. As the support arm 10 continues to rotate, the block 3 drives the bearing ring to leave the outlet 34, thereby completing the feeding. The cylinder 22 then drives the block 3 down to a height flush with the grinding strip 13.

[0033] A hydraulic cylinder 36 is provided at the lower part of the feed plate 30, and the hydraulic cylinder 36 is driven to connect a support plate 37, and the support plate 37 can completely cover the opening 33. In the normal state, the support plate 37 moves to the opposite side of the opening 33 under the action of the hydraulic cylinder 36, and supports the moving bearing ring on the feed plate 30 to prevent the bearing ring from falling from the opening 33. In the loading state, the support plate 37 moves from below the opening 33 to expose the opening 33.

[0034] like Figure 8 , Fig. 9As shown, the discharging mechanism 5 includes a discharge plate 38 located above the rotating disk 8, a lowering plate 43 is connected to the side of the discharge plate 38 away from the rotating disk 8, the height of the lowering plate 43 close to the discharge plate 38 is higher than the height of the end away from the discharge plate 38, the front and rear sides of the discharge plate 38 and the lowering plate 43 are both provided with a second retaining edge 41, the side of the discharge plate 38 close to the rotating disk 8 is connected to a second stopper 40, the discharge plate 38 is provided with a second opening 39, the second opening 39 is connected to the rear side of the discharge plate 38, and an inlet 42 is provided on the second retaining edge 41 at the rear side corresponding to the second opening 39. A push block 44 is provided in the middle of the second stopper 40, and a second hydraulic cylinder 46 is connected to the side of the second stopper 40 through a support rod 45, and the second hydraulic cylinder 46 is connected to the push block 44 by driving. When the support arm 10 drives the block 3 to move close to the discharge mechanism 5, the cylinder 22 controls the block 3 to rise, so that the bottom of the bearing ring on the block 3 is slightly higher than the upper end surface of the discharge plate 38. After the bearing ring reaches the discharge plate 38 through the inlet 42, the cylinder 22 controls the block 3 to descend, and the block 3 descends through the second opening 39, while the bearing ring is stuck by the discharge plate 38, and the bearing ring is removed from the block 3 and remains on the discharge plate 38. The second hydraulic cylinder 46 controls the push block 44 to move toward the discharge plate 38, pushes the bearing ring on the discharge plate 38 to the unloading plate 43, and moves the bearing ring along the inclined unloading plate 43 to complete the unloading.

[0035] The top end of the clamping block 3 is located at the second opening 39, and can support the pushed bearing ring.

[0036] like Figure 3 As shown, the guide ring 12 includes a convex ring 1 27, a convex ring 28, and a convex ring 3 29, and the widths of the convex ring 1 27, the convex ring 28, and the convex ring 3 29 increase in sequence. The convex ring 1 27, the convex ring 28, and the convex ring 3 29 have a smooth transition, so that the rotating wheel 20 can move along the convex ring 1 27, the convex ring 28, and the convex ring 3 29. The convex ring 1 27 is correspondingly arranged in the area where the feeding mechanism 4 and the discharging mechanism 5 are located. The bearing ring does not need to rotate during loading and unloading, and the width of the convex ring 1 27 is the smallest. At this time, the driving gear 11 on the support arm 10 will not contact the rack 16, so that the block 3 will not rotate.

[0037] The second convex ring 28 is arranged near the feeding mechanism 4. After the material is loaded, it is first ground with less force to complete the preliminary grinding.

[0038] The convex ring three 29 is arranged near the discharging mechanism 5. After the initial grinding, the grinding force needs to be increased. Under the action of the convex ring three 29, the support arm 10 moves a certain distance toward the mounting frame 2, and the force of pressing the bearing ring on the grinding strip 13 is increased, thereby performing a stronger grinding process.

[0039] When the driving gear 11 reaches the area where the second convex ring 28 and the third convex ring 29 are located, since the width of the third convex ring 29 is greater than that of the second convex ring 28, the support arm 10 will move a certain distance toward the mounting frame 2, and the driving gear 11 will be closer to the mounting frame 2. In order to ensure that the driving gear 11 can normally mesh with the rack 16, the width of the rack 16 opposite to the second convex ring 28 should be set to be greater than the width of the rack 16 opposite to the third convex ring 29, so as to ensure that the driving gear 11 can normally mesh with the rack 16 when it is in the area of ​​the second convex ring 28 and the third convex ring 29, without being separated or stuck.

[0040] like Figure 4 As shown, a guide groove 17 is formed on the side of the support arm 10 along its length direction, and a guide block 25 is connected to the side of the support frame 9 close to the support arm 10 , and the guide block 25 is located in the guide groove 17 .

[0041] like Figure 2 As shown, a suction chamber 14 is provided at the inner side of the mounting frame 2 below the grinding strip 13, a suction fan 15 is provided inside the mounting frame 2, an air inlet of the suction fan 15 is connected to the suction chamber 14, and a filter is provided inside the suction chamber 14. Waste generated during the grinding process is sucked into the suction chamber 14 by the suction fan 15, so as to prevent the waste from falling on the rack 16 and affecting the normal meshing between the driving gear 11 and the rack 16.

[0042] like Figure 4 As shown, an introduction slope 23 is provided at the upper end of the block 3, and the diameter of the upper end of the introduction slope 23 is smaller than the diameter of the lower end of the introduction slope 23, so that the block 3 can be better inserted into the bearing ring from top to bottom to complete the fixation.

[0043] A rubber ring 24 is arranged on the periphery of the clamping block 3. The rubber ring 24 is located between the periphery of the clamping block 3 and the inner wall of the bearing ring, and plays a role in protecting the bearing ring to avoid squeezing or scratching the inner wall of the bearing ring.

[0044] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
