DETAILED DESCRIPTION

[0034] 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.

[0035] like Figures 1 to 12 As shown, the present invention provides a bearing ring grinding device, comprising a support 1 and a bearing ring 2, wherein the support 1 is provided with a vertical plate 11 and a vertical plate 2 12, and a guide slide 13 is fixedly connected between the two, and the bearing ring 2 can roll along the top of the guide slide 13, and further comprising: a clamping mechanism 3, which is mounted on the vertical plate 11; a grinding assembly 2 4, which is arranged on the guide slide 13;

[0036] The clamping mechanism 3 includes a telescopic component 31, a rotating component 32 and a clamping component 33. The telescopic component 31 and the rotating component 32 are both fixedly mounted on the vertical plate 11. The clamping component 33 is fixedly mounted on the telescopic component 31. The telescopic component 31 is used to drive the clamping component 33 and penetrate into the bearing ring 2 to clamp the bearing ring 2. The rotating component 32 drives the clamping component 33 to rotate through the transmission of the telescopic component 31.

[0037] The grinding assembly 2 4 includes an elastic telescopic rod 41 connected to one end of the guide slide 13 by a bearing, and a grinding block 2 42 capable of contacting the outer peripheral surface of the bearing ring 2 is fixedly connected to one end of the elastic telescopic rod 41, and an elastic slider 1 46 is elastically connected to the guide slide 13, and a bending plate 43 is hinged at the bottom of the guide slide 13, and a connecting rod 2 44 and a cylinder 3 45 are coaxially hinged at the bent end of the bending plate 43, and the other ends of the connecting rod 2 44 and the cylinder 3 45 are respectively hinged to the bottom of the guide slide 13 and the bottom of the elastic slider 1 46, and two groups of staggered and mutually connected arc grooves 48 and straight grooves 49 are opened on the elastic telescopic rod 41, and an elastic paddle 410 is arranged at the connection point between the arc groove 48 and the straight groove 49 near the grinding block 2 42, and a convex shaft 1 47 capable of sliding in the arc groove 48 is fixedly connected to the top of the elastic slider 1 46.

[0038] By adopting the above scheme, the clamping assembly 33 is pushed into the bearing ring 2 by running the telescopic assembly 31 to clamp the bearing ring 2, and the rotating assembly 32 is driven to rotate through the telescopic assembly 31, and the grinding block 2 42 grinds the outer periphery of the bearing ring 2. After the grinding is completed, the cylinder 3 45 is operated to contract and drive the bending plate 43 to rotate around the axis. After the grinding is completed, the bearing ring 2 is discharged through the bending plate 43, and the bottom end of the bending plate 43 pushes the elastic slider 1 46 and the convex shaft 1 47 through the connecting rod 2 44. The top end of the cam 47 is guided by the elastic paddle 410 in the straight groove 49 and enters the arc groove 48, so that the elastic telescopic rod 41 drives the grinding block 2 42 to rotate 180 degrees as a whole to change the direction. When the cylinder 3 45 is extended and reset, it can drive the connecting rod 2 44 and the elastic slider 1 46 to reset through the bending plate 43, so that the top end of the cam 47 is reset along the next set of straight grooves 49 to ensure that the grinding block 2 42 is worn more evenly and avoid the problem of unilateral wear of the grinding block 2 42 and reduced grinding effect.

[0039] like Figure 2-Figure 5 As shown, the guide slide 13 is also elastically connected and hinged with an elastic baffle 14. In the initial state, one end of the bending plate 43 abuts against the lower surface of the end of the elastic baffle 14 and makes the elastic baffle 14 have a tendency to rotate counterclockwise;

[0040] By adopting the above scheme, when the bending plate 43 rotates around the axis to open, the squeezing of the elastic baffle 14 will be released. At the same time, the elastic baffle 14 will rotate counterclockwise around the axis due to its own elastic force. At this time, the next ring to be ground will be blocked until the bending plate 43 is reset and closed.

[0041] like Figure 1-Figure 4 and Figure 6-Figure 8 As shown, the telescopic assembly 31 includes a limit cross bar 311 and a cylinder 313 fixedly connected to the vertical plate 11, the limit cross bar 311 is sleeved with a frame 312 on the outside, the middle bearing of the frame 312 is connected with a spline shaft 314, the other end of the spline shaft 314 is fixedly connected to the clamping assembly 33, and the output end of the cylinder 313 is fixedly connected to the bottom of the frame 312;

[0042] The rotating assembly 32 includes a gear motor 321 fixedly connected to the vertical plate 11 and a gear plate 322 sleeved on the outer periphery of the spline portion of the spline shaft 314. The output end of the gear motor 321 is meshedly connected with the gear plate 322. The output end of the gear motor 321 is also provided with two sets of discs, and the edge of the gear plate 322 is located between the two sets of discs.

[0043] By adopting the above solution, the cylinder 1 313 is operated to contract. At this time, under the limit of the limit cross bar 311, the frame 312 will drive the clamping assembly 33 to move through the spline shaft 314 and enter the inner cavity of the bearing ring 2;

[0044] The running gear motor 321 can drive the spline shaft 314 to rotate through the gear plate 322. When the spline shaft 314 moves in the gear plate 322, the gear plate 322 still remains sleeved on the outside of the spline shaft 314 and transmits power.

[0045] like Figure 1-Figure 4 and Figure 7-Figure 11 As shown, the vertical plate 11 is also fixedly connected with a driving motor 5, the output end of the driving motor 5 extends between the vertical plate 11 and the vertical plate 2 12 and is installed with a driving wheel for contacting the outer peripheral surface of the bearing ring 2; the clamping assembly 33 includes a three-way block 331 with a radius smaller than the inner diameter of the bearing ring 2, the three-way block 331 has a ring array inside and is movably connected with a support block 332, the three-way block 331 is also annularly arrayed and hinged with a connecting rod 1 333, the support block 332 is fixedly connected with a guide rod 334 that can slide in one end of the connecting rod 1 333, the connecting rod 1 333 is also hinged with a cylinder 2 335, and the other end of the cylinder 2 335 is hinged with the three-way block 331; the end of the connecting rod 1 333 away from the guide rod 334 is elastically hinged with a grinding block 1 3331;

[0046] By adopting the above solution, when the clamping assembly 33 enters the bearing ring 2, the second cylinder 335 is shortened by running, so that the guide rod 334 slides at the end of the connecting rod 1 333, so that the support block 332 moves outward to squeeze the inner wall of the bearing ring 2 to achieve the clamping of the bearing ring 2;

[0047] By operating the cylinder 2 335 to extend and rotate the connecting rod 1 333, the guide rod 334 is forced to slide in the connecting rod 1 333 and drive the support block 332 to shrink into the three-way block 331. At the same time, the grinding block 1 3331 will expand outward and contact the inner wall of the bearing ring 2. At this time, the bearing ring 2 is driven to rotate by running the drive motor 5, so that the grinding block 1 3331 grinds the inner wall of the bearing ring 2.

[0048] like Figure 1-Figure 4 , Figure 7 and Fig.12 As shown, the vertical plate 1 11 and the vertical plate 2 12 are also provided with a grinding assembly 3 6 for grinding the side of the bearing ring 2;

[0049] The grinding assembly 3 6 comprises an elastic slider 2 61 elastically connected between the vertical plate 1 11 and the vertical plate 2 12 and having a vertical downward trend, and symmetrically arranged oblique grooves 62 at both ends of the elastic slider 2 61, and two groups of limit rods 63 are movably sleeved on the vertical plate 1 11 and the vertical plate 2 12, and one end of each group of limit rods 63 is fixedly connected to a grinding sheet 64 located inside the vertical plate 1 11 and the vertical plate 2 12, and a convex shaft 2 65 capable of sliding in the oblique groove 62 is fixedly connected to the top of the grinding sheet 64, and a roller 66 is movably connected to the bottom of the elastic slider 2 61;

[0050] In the initial state, the bottom of the roller 66 abuts against the outer peripheral surface of the bearing ring 2;

[0051] By adopting the above scheme, in the process of fixing the bearing ring 2 by the clamping assembly 33, the bearing ring 2 will move upward and push the elastic slider 61 upward through the roller 66, thereby forcing the cam 65 to move through the inclined groove 62. At the same time, under the limit of the limit rod 63, the two grinding discs 64 move toward each other and contact the two ends of the bearing ring 2 respectively to perform grinding operations.

[0052] The working principle and use process of the present invention:

[0053] First, the bearing ring is transported to the top of the bending plate 43 through the guide slide 13, and the telescopic component 31 is operated to push the clamping component 33 into the bearing ring 2 to clamp the bearing ring 2. During the clamping process, the bearing ring 2 will gradually become coaxial with the clamping component 33. At this time, the bearing ring 2 will move upward and contact the driving wheel at the output end of the driving motor 5. At the same time, the bearing ring 2 will also squeeze the grinding block 2 42 to shrink the elastic telescopic rod 41. Then, the rotating component 32 is operated to pass through the telescopic component 31 and drive the clamping component 33 to rotate. At this time, the grinding block 2 42 will grind the outer periphery of the bearing ring 2.

[0054] After the grinding is completed, the cylinder 3 45 is contracted to drive the bending plate 43 to rotate around the axis. At this time, the bearing ring 2 after grinding will be discharged through the bending plate 43. At the same time, the bottom end of the bending plate 43 will also push the elastic slider 1 46 and the convex shaft 1 47 to move through the connecting rod 2 44, so that the top of the convex shaft 1 47 enters the arc groove 48 in the straight groove 49 under the guidance of the elastic paddle 410, so that the elastic telescopic rod 41 drives the grinding block 2 42 to rotate 180 degrees as a whole to change the direction. When the cylinder 3 45 is extended and reset, it can drive the connecting rod 2 44 and the elastic slider 1 46 to reset through the bending plate 43, so that the top of the convex shaft 1 47 is reset along the next group of straight grooves 49.

[0055] When the bending plate 43 rotates around the axis to open, the compression on the elastic baffle 14 will also be released. At the same time, the elastic baffle 14 will rotate counterclockwise around the axis under the action of its own elastic force. At this time, the next ring to be ground will be blocked until the bending plate 43 is reset and closed;

[0056] When the clamping assembly 33 enters the bearing ring 2, the second cylinder 335 is shortened by running, so that the guide rod 334 slides on the end of the connecting rod 1 333, so that the support block 332 moves outward to squeeze the inner wall of the bearing ring 2 to achieve the clamping of the bearing ring 2;

[0057] The connecting rod 1 333 is rotated by running the cylinder 2 335 to extend, forcing the guide rod 334 to slide in the connecting rod 1 333 and drive the support block 332 to shrink into the three-way block 331. At the same time, the grinding block 1 3331 will expand outward and contact the inner wall of the bearing ring 2. At this time, the bearing ring 2 is driven to rotate by running the driving motor 5, so that the grinding block 1 3331 grinds the inner wall of the bearing ring 2.

[0058] When the clamping assembly 33 fixes the bearing ring 2, the bearing ring 2 will move upward and push the elastic slider 61 upward through the roller 66, thereby forcing the cam 65 to move through the inclined groove 62. At the same time, under the limit of the limit rod 63, the two grinding discs 64 move toward each other and contact the two ends of the bearing ring 2 respectively to perform grinding operations.
