Description

Technical Field

[0001] The invention relates to the technical field of bearing processing, in particular to a grinding device for processing a bearing ring. Background Art

[0002] ‌The bearing consists of four parts: an inner ring, an outer ring, rolling elements and a retaining cage. An annular groove is provided on the inner circumference of the outer ring of the bearing for the rolling elements to roll on. During the production process of the outer ring of the bearing, burrs are prone to appear in the annular groove. Therefore, the annular groove of the outer ring of the bearing needs to be polished. Since the annular groove of the outer ring of the bearing is located on the inner circumference of the outer ring of the bearing, a grinding wheel needs to be first extended into the inner side of the outer ring of the bearing during polishing, and then the outer circumference of the grinding wheel needs to be laterally moved close to the annular groove. The lateral movement distance of the grinding wheel is difficult to control, which can easily affect the accuracy of the grinding of the outer ring of the bearing. High temperature will occur during polishing, and the grinding wheel is prone to be stained with a lot of debris, which will affect the continuous and efficient polishing of the outer ring of the bearing. Summary of the invention

The grinding efficiency of the annular groove of the bearing outer ring is high, and the grinding accuracy of the annular groove of the bearing outer ring is high. During the grinding process, air can be continuously blown towards the grinding wheel, which is beneficial to cooling the grinding wheel and can blow away the debris on the grinding wheel in time, which is beneficial to continuous and efficient grinding of the bearing outer ring, and can effectively solve the problems in the background technology.

An inner gear ring is provided above the circular table plate, and the left and right sides of the inner gear ring are respectively connected to the left and right sides of the circular table plate through two supporting bent frames. A middle plate is provided above the center of the inner gear ring, and the front and rear sides of the middle plate are respectively connected to the front and rear sides of the inner gear ring through two supporting bent plates. The middle part of the middle plate is rotatably connected to the top of the vertical cylinder through a bearing, and the outer peripheral side of the bottom end of the vertical cylinder is fixedly sleeved with the middle circular hole of the planetary rotating rod. The left and right ends of the planetary rotating rod are respectively rotatably connected to the top ends of two vertical planetary rotating cylinders through bearings, and the two planetary rotating cylinders are both connected to the planetary power assembly. The grinding wheel extends into the positioning mechanism and is installed at the bottom of the two planetary drums; The detachable grinding mechanism is installed at the bottom of the grinding wheel extending into the positioning mechanism.

[0005] The support frame composed of the base, pillars and round table plates is convenient for supporting the planetary movable mechanism. The planetary power assembly can drive the vertical cylinder to rotate relative to the middle plate. At the same time, the planetary rotary rod rotates with the vertical cylinder. The two planetary rotating cylinders can revolve around the center of the vertical cylinder. At the same time, the two planetary rotating cylinders can also rotate around their own centers. The grinding wheel extends into the positioning mechanism to drive the disassembly type grinding mechanism to extend into both sides of the inner annular groove of the bearing ring. The rotation of the planetary rotating cylinder drives the disassembly type grinding mechanism to rotate, and grinds the inner annular groove of the bearing ring.

The bottom end of the power shaft passes through the center of the vertical cylinder and is fixedly connected to the middle of the sun gear. The two planetary rotating cylinders are located at the lower side of the planetary rotating rod and are respectively fixedly sleeved with two planetary gears, and each planetary gear is respectively meshed and connected with the sun gear and the inner ring gear.

[0007] Furthermore, the grinding wheel insertion mechanism includes a grinding wheel insertion assembly, an inner folding pushing assembly and an in-place straightening assembly. The bottom ends of the two planetary rotating drums are respectively connected to two grinding wheel insertion assemblies, the inner sides of the two supporting curved frames are respectively installed with two inner folding pushing assemblies, and the left and right sides of the top of the inner gear ring are respectively installed with two in-place straightening assemblies.

Due to the direction of the movable shaft, the bottom ends of the two swing cylinders are close to each other or away from each other. When the bottom ends of the two swing cylinders are close to each other, the horizontal position of the bottom ends of the two swing cylinders rises, which can drive the two detachable grinding mechanisms to rise when they are close to each other. At this time, it is convenient to place bearing rings under the two detachable grinding mechanisms.

Due to the gravity of the swing cylinder and the detachable grinding mechanism, the swing cylinder gradually returns to a vertical state.

The prism 1 cooperates with the grinding wheel to prevent the grinding wheel from rotating relative to the prism 1, so that the swing cylinder can stably drive the grinding wheel to rotate. When the two swing cylinders are restored from a state of being close to each other to a vertical state, the two sides of the two grinding wheels that are away from each other extend into the two sides of the annular groove on the inner side of the bearing ring, respectively, so as to grind two symmetrical points of the bearing ring.

[0012] Furthermore, it also includes a concentric clamping mechanism for the bearing ring, which includes a slide groove, a slider, a fan-shaped support plate, an arc clamping plate and a radial synchronous displacement component.

The left and right ends of the follower rotary rod are respectively rotatably connected to the outer peripheral sides of the bottom ends of the two planetary rotating cylinders through bearings. The middle part of the follower rotary rod is provided with a prismatic hole corresponding to the top end of the prism 2.

[0015] Compared with the prior art, the beneficial effects of the grinding device for bearing ring processing are: 1. The planetary power assembly can drive the vertical cylinder to rotate relative to the middle plate. At the same time, the planetary rotating rod rotates with the vertical cylinder. The two planetary rotating cylinders can revolve around the center of the vertical cylinder. At the same time, the two planetary rotating cylinders can also rotate around their own centers. The grinding wheel extends into the positioning mechanism to drive the disassembly type grinding mechanism to extend into both sides of the inner annular groove of the bearing ring. The rotation of the planetary rotating cylinder drives the disassembly type grinding mechanism to rotate, and grinds the inner annular groove of the bearing ring. The revolution of the planetary rotating cylinder drives the disassembly type grinding mechanism to move in a circle in the inner annular groove of the bearing ring, and comprehensively grinds all positions of the inner annular groove of the bearing ring.

[0016] 2. When the bottom ends of the two pendulum cylinders are close to each other, the horizontal positions of the bottom ends of the two pendulum cylinders rise, which can drive the two disassembly type grinding mechanisms to rise when they are close to each other. At this time, it is convenient to place the bearing rings under the two disassembly type grinding mechanisms, and insert the bottom ends of the straightening columns into the pendulum cylinders. At this time, the pendulum cylinders cannot move relative to the planetary rotating cylinders, and both the planetary rotating cylinders and the pendulum cylinders maintain a stable vertical state. When the planetary rotating cylinders and the pendulum cylinders rotate, they can stably drive the disassembly type grinding mechanism to rotate. When the radial synchronous displacement assembly drives the three circular arc clamps to move close to each other synchronously with the help of the slider and the fan-shaped support plate, the three circular arc clamps gradually clamp the outside of the bearing ring. Due to the synchronous movement of the three circular arc clamps, the center of the bearing ring and the round table plate can be coincident. With the work of the planetary movable mechanism, the disassembly type grinding mechanism can grind the annular groove on the inner side of the bearing ring with high accuracy.

[0017] 3. The grinding efficiency of the annular groove of the outer ring of the bearing is high, and the grinding accuracy of the annular groove of the outer ring of the bearing is high. During the grinding process, air can be continuously blown towards the grinding wheel, which is beneficial to cooling the grinding wheel and blowing away the debris on the grinding wheel in time, which is beneficial to continuous and efficient grinding of the outer ring of the bearing.

An inner gear ring 22 is provided above the truncated plate 13, and the left and right sides of the inner gear ring 22 are respectively connected to the left and right sides of the truncated plate 13 through two supporting bent frames 21. A middle plate 24 is provided above the center of the inner gear ring 22, and the front and rear sides of the middle plate 24 are respectively connected to the front and rear sides of the inner gear ring 22 through two supporting bent plates 23. The middle part of the middle plate 24 is rotatably connected to the top of the vertical cylinder 25 through a bearing, and the outer peripheral side of the bottom end of the vertical cylinder 25 is fixedly sleeved with the middle circular hole of the planetary rotating rod 26. The left and right ends of the planetary rotating rod 26 are respectively rotatably connected to the tops of two vertical planetary rotating cylinders 27 through bearings, and the two planetary rotating cylinders 27 are both connected to the planetary power assembly. The planetary power assembly includes a planetary gear 28, a sun gear 29, a motor frame 210, a power motor 211 and a power shaft 212. The tops of the two supporting bent plates 23 are fixedly connected to the two ends of the motor frame 210 by screws. The power motor 211 is installed in the middle of the motor frame 210. The output shaft at the bottom of the power motor 211 is fixedly connected to the top of the power shaft 212. The bottom end of the power shaft 212 passes through the center of the vertical cylinder 25 and is fixedly connected to the middle of the sun gear 29. The two planetary rotating cylinders 27 are located at the lower side of the planetary rotating rod 26 and are respectively fixedly sleeved with two planetary gears 28. Each planetary gear 28 is respectively meshed and connected with the sun gear 29 and the inner ring gear 22. The motor frame 210 is used to support and install the power motor 211. When the power motor 211 works, it drives the power shaft 212 to rotate. The power shaft 212 drives the sun gear 29 to rotate. The sun gear 29, the planetary gears 28 and the inner ring gear 22 cooperate to allow the sun gear 29 to drive the two planetary gears 28 to perform planetary motion, thereby driving the two planetary rotating drums 27 to perform planetary motion, that is, the two planetary rotating drums 27 revolve around the center of the sun gear 29, and the two planetary rotating drums 27 rotate around their respective centers.

[0021] The grinding wheel insertion mechanism 3 is installed at the bottom of the two planetary drums 27; The grinding wheel insertion mechanism 3 includes a grinding wheel insertion assembly, an inner folding pushing assembly and an in-place straightening assembly. The bottom ends of the two planetary rotating drums 27 are respectively connected to two grinding wheel insertion assemblies, the inner sides of the two supporting curved frames 21 are respectively installed with two inner folding pushing assemblies, and the top left and right sides of the inner gear ring 22 are respectively installed with two in-place straightening assemblies. The inner folding pushing assembly is used to push the grinding wheel insertion assembly to move relative to the planetary rotating drum 27, and the in-place straightening assembly is used to straighten the grinding wheel insertion assembly relative to the planetary rotating drum 27, so that the planetary rotating drum 27 can stably drive the grinding wheel insertion assembly to rotate.

[0022] The grinding wheel insertion assembly includes a movable shaft 31 and a swing cylinder 32. The bottom end of each planetary rotating cylinder 27 is movably connected to the top end of the swing cylinder 32 through two movable shafts 31. The bottom end of the swing cylinder 32 is closed and the movable shaft 31 is perpendicular to the planetary rotating rod 26. Due to the direction of the movable shaft 31, the bottom ends of the two swing cylinders 32 are close to each other or away from each other. When the bottom ends of the two swing cylinders 32 are close to each other, the horizontal position of the bottom ends of the two swing cylinders 32 rises, which can drive the two detachable grinding mechanisms 4 to rise when they are close to each other. At this time, it is convenient to place the bearing ring 7 under the two detachable grinding mechanisms 4.

[0023] The inner folding push assembly includes a swinging electric telescopic rod 33 and a push block 34. The inner sides of the two supporting curved frames 21 are respectively fixedly connected to one end of the two horizontal swinging electric telescopic rods 33, and the other ends of the two swinging electric telescopic rods 33 are respectively fixedly connected to the push blocks 34. When the inner folding push assembly needs to work, the power motor 211 works to make the two swing cylinders 32 correspond to the two push blocks 34 respectively, the two swinging electric telescopic rods 33 extend to push the two swing cylinders 32 closer to each other through the two push blocks 34, the two swinging electric telescopic rods 33 shorten, and the two push blocks 34 no longer contact the two swing cylinders 32. Due to the gravity of the swing cylinder 32 and the detachable grinding mechanism 4, the swing cylinder 32 gradually returns to a vertical state. At this time, the two detachable grinding mechanisms 4 are away from each other, and the two detachable grinding mechanisms 4 are gradually located on the inner side of the bearing ring 7.

[0024] The in-place straightening assembly includes a top frame 35, an upward pull-up electric telescopic rod 36, an electromagnet 37, an in-place straightening column 38 and an iron block 39. Two in-place straightening columns 38 are respectively inserted in the two planetary rotating cylinders 27. The bottom ends of the two in-place straightening columns 38 are respectively inserted into the interior of the two swing cylinders 32. The top ends of the two in-place straightening columns 38 are respectively fixedly connected to two iron blocks 39. The left and right sides of the top of the inner gear ring 22 are respectively fixedly connected to two top frames 35. The tops of the two top frames 35 are respectively fixedly connected to the top ends of the two upward pull-up electric telescopic rods 36. The bottom ends of the two upward pull-up electric telescopic rods 36 are respectively fixedly connected to two electromagnets 37. The two electromagnets 37 are respectively arranged corresponding to the two iron blocks 39. When the inward folding pushing assembly needs to push the two pendulum cylinders 32 closer to each other, the upward-pulling electric telescopic rod 36 is extended to allow the electromagnet 37 to approach the iron block 39 on the top of the in-place straightening column 38. The electromagnet 37 is energized to work, and the magnetism of the electromagnet 37 attracts the iron block 39. The upward-pulling electric telescopic rod 36 is shortened, and the in-place straightening column 38 is pulled up relative to the planetary rotating cylinder 27 by the electromagnet 37 and the iron block 39 until the bottom end of the in-place straightening column 38 is completely pulled out of the pendulum cylinder 32. At this time, there is no influence of the in-place straightening column 38 on the pendulum cylinder 32, and the pendulum cylinder 32 can move relative to the bottom of the planetary rotating cylinder 27 through the movable shaft 31. When the pendulum cylinder 32 returns to a vertical state, the upward-pulling electric telescopic rod 36 is extended, and the in-place straightening column 38 is pushed relative to the planetary rotating cylinder 27 by the electromagnet 37 and the iron block 39. The rotating drum 27 moves downward until the bottom end of the straightening column 38 in place is inserted into the swing drum 32. At this time, the swing drum 32 cannot move relative to the planetary rotating drum 27. The planetary rotating drum 27 and the swing drum 32 both maintain a stable vertical state. When the planetary rotating drum 27 and the swing drum 32 rotate, they can stably drive the disassembly type grinding mechanism 4 to rotate, so that the disassembly type grinding mechanism 4 can stably grind the annular groove on the inner side of the bearing ring 7. In order to prevent the magnetic attraction of the electromagnet 37 and the iron block 39 from affecting the rotation of the straightening column 38 in place, the planetary rotating drum 27 and the swing drum 32, the electromagnet 37 is powered off and turned off, and the electric telescopic rod 36 is pulled up to shorten, so that the electromagnet 37 leaves the iron block 39. The electric telescopic rod 36 and the electromagnet 37 will no longer interfere with the straightening column 38 in place rotating with the planetary rotating drum 27 and the swing drum 32.

[0025] The detachable grinding mechanism 4 is installed at the bottom of the grinding wheel extending into the positioning mechanism 3.

[0026] The detachable grinding mechanism 4 includes a prism 1 41 and a grinding wheel 43. A vertical prism 1 41 is fixedly connected to the middle of the bottom end of each swing tube 32. A grinding wheel 43 is installed on the prism 1 41. The grinding wheel 43 is provided with a prism hole that matches the prism 1 41. The prism 1 41 cooperates with the grinding wheel 43 to prevent the grinding wheel 43 from rotating relative to the prism 1 41, so that the swing tube 32 can stably drive the grinding wheel 43 to rotate. When the two swing tubes 32 are restored from the state of being close to each other to the vertical state, the two sides of the two grinding wheels 43 that are away from each other extend into the two sides of the annular groove on the inner side of the bearing ring 7, respectively, so as to grind two symmetrical points of the bearing ring 7.

[0027] The detachable grinding mechanism 4 also includes a stud 42, a washer 44, and a disassembly nut 45. The bottom end of each prism 41 is fixedly connected to the top end of the stud 42. A washer 44 is sleeved on the position of the prism 41 located on the lower side of the grinding wheel 43. The lower side horizontal position of the washer 44 is lower than the horizontal position of the bottom end of the prism 41. A disassembly nut 45 is threadedly connected to the stud 42. The top end of the disassembly nut 45 presses the washer 44, thereby realizing the detachable installation of the grinding wheel 43.

[0028] When in use, the support frame 1 composed of the base 11, the pillar 12 and the frustum plate 13 can conveniently support the planetary movable mechanism 2, and the planetary power assembly can drive the vertical cylinder 25 to rotate relative to the middle plate 24. At the same time, the planetary rotary rod 26 rotates with the vertical cylinder 25, and the two planetary rotating cylinders 27 can revolve around the center of the vertical cylinder 25. At the same time, the two planetary rotating cylinders 27 can also rotate around their own centers. The grinding wheel extends into the positioning mechanism 3 to drive the disassembly type grinding mechanism 4 to extend into both sides of the inner annular groove of the bearing ring 7. The rotation of the planetary rotating cylinder 27 drives the disassembly type grinding mechanism 4 to rotate, and grinds the inner annular groove of the bearing ring 7. The revolution of the planetary rotating cylinder 27 drives the disassembly type grinding mechanism 4 to make a circular movement in the inner annular groove of the bearing ring 7, and comprehensively grinds all positions of the inner annular groove of the bearing ring 7.

[0029] For example 2, please refer to Figures 1 to 8 This embodiment provides a technical solution: a grinding device for bearing ring processing. The structure of this embodiment is roughly the same as that of the first embodiment, except that: It also includes a bearing ring concentric clamping mechanism 5, which includes a slide groove 51, a slider 52, a fan-shaped support plate 53, an arc clamping plate 54 and a radial synchronous displacement component. Three slide grooves 51 are arranged in an annular array on the frustum plate 13, and the slide grooves 51 are distributed radially along the frustum plate 13. A slider 52 is slidably connected in each slide groove 51, and a fan-shaped support plate 53 is fixedly connected to the top of each slider 52. An arc clamping plate 54 is fixedly connected to the top of each fan-shaped support plate 53 away from the center of the frustum plate 13. The three sliders 52 are all connected to the radial synchronous displacement component, and the center of the circle where the three arc clamping plates 54 are located, the center of the frustum plate 13, and the center of the inner gear ring 22 are arranged to coincide.

[0030] The radial synchronous displacement assembly includes a compression spring 55, a roller 56, a control ring 57, a triangular push plate 58, an outer gear ring 59, a control gear 510, and a clamping motor 511. The bottom end of each slider 52 is rotatably connected to a roller 56, and one end of each slide groove 51 close to the center of the frustum plate 13 is connected to the corresponding slider 52 through a compression spring 55. The bottom of the frustum plate 13 is rotatably connected to a control ring 57. Three triangular push plates 58 are arranged in an annular array on the inner circumference of the control ring 57. The inclined surface of each triangular push plate 58 is rollingly connected to the corresponding roller 56. The outer side of the control ring 57 is fixedly sleeved with an outer gear ring 59. The upper side edge of the frustum plate 13 is fixedly connected to the clamping motor 511. The output shaft at the bottom of the clamping motor 511 is fixedly connected to the control gear 510. The control gear 510 is meshed with the outer gear ring 59. The clamping motor 51 1 works, and the control ring 57 is driven to rotate counterclockwise relative to the circular table plate 13 by the transmission of the control gear 510 and the outer gear ring 59. The inclined surface of each triangular push plate 58 gradually pushes the roller 56 toward the center of the circular table plate 13, thereby pushing the three sliders 52 to move synchronously along their respective slide grooves 51 toward the center of the circular table plate 13. At this time, the three compression springs 55 are all compressed, and the three arc clamping plates 54 gradually clamp the outer side of the bearing ring 7. The clamping motor 511 works, and the control ring 57 is driven to rotate clockwise relative to the circular table plate 13 by the transmission of the control gear 510 and the outer gear ring 59. The inclined surface of the triangular push plate 58 begins to no longer push the roller 56. At this time, the three compression springs 55 reset and extend, pushing the three sliders 52 to move synchronously along their respective slide grooves 51 toward the edge of the circular table plate 13. At this time, the three arc clamping plates 54 release the bearing ring 7.

[0031] The radial synchronous displacement component is used to drive the three sliders 52 to move synchronously in the three slide grooves 51 toward the center of the frustum plate 13 or away from the center of the frustum plate 13. When the bearing ring 7 to be polished is placed on the inner side of the three arc clamps 54, the three fan-shaped support plates 53 can pre-support the bottom of the bearing ring 7. When the radial synchronous displacement component drives the three arc clamps 54 to move synchronously closer to each other with the help of the sliders 52 and the fan-shaped support plates 53, the three arc clamps 54 gradually clamp the outer side of the bearing ring 7. Due to the synchronous movement of the three arc clamps 54, the center of the bearing ring 7 can coincide with the center of the frustum plate 13. In cooperation with the work of the planetary movable mechanism 2, the disassembly grinding mechanism 4 has high grinding accuracy for the inner annular groove of the bearing ring 7.

[0032] For example 3, please refer to Figures 1 to 8 This embodiment provides a technical solution: a grinding device for processing a bearing ring. The structure of this embodiment is roughly the same as that of the second embodiment, except that: It also includes a grinding wheel heat dissipation and chip blowing mechanism 6, which includes an air pump 61, a hose 62, a lifting assembly, a lifting plate 65, an air cylinder 66, a rotary joint 67, a rotating drum 68, an air blowing transverse pipe 69 and a planetary gear follower assembly. A through hole 14 is opened in the middle of the frustum plate 13, and a lifting plate 65 is connected to the middle part of the upper side of the base 11 through a lifting assembly. The middle part of the lifting plate 65 is fixedly connected to the bottom end of the air cylinder 66, and the bottom center of the air cylinder 66 is connected to the air outlet of the air pump 61 through a hose 62. The air pump 61 is installed on the base 11, and the top of the air cylinder 66 is connected to the bottom end of the rotating drum 68 through a rotary joint 67. Two air blowing transverse pipes 69 are respectively arranged on the left and right sides of the top of the rotating drum 68, and a planetary gear follower assembly is arranged on the top of the rotating drum 68.

[0033] The lifting assembly includes a guide rod 63 and a lifting electric telescopic rod 64. The sliding hole on the lifting plate 65 is slidably connected to the vertical guide rod 63. The bottom end of the guide rod 63 is fixedly connected to the upper side of the base 11. The bottom of the lifting plate 65 is fixedly connected to the upper side of the base 11 through the vertical lifting electric telescopic rod 64. The guide rod 63 and the lifting plate 65 are limited and guided so that the lifting plate 65 can only move up and down. The extension and shortening of the lifting electric telescopic rod 64 can drive the lifting plate 65 to rise or fall.

[0034] The lifting assembly drives the lifting plate 65 to rise. At this time, the two air blowing transverse tubes 69 on the rotating drum 68 are aligned with the two grinding wheels 43, and the planetary gear follower assembly allows the rotating drum 68 to rotate synchronously with the planetary rotating rod 26. At this time, when the planetary movable mechanism 2 is in operation, the two air blowing transverse tubes 69 are always aligned with the two grinding wheels 43. The setting of the rotating joint 67 allows the rotating drum 68 to rotate relative to the air cylinder 66. The air pump 61 pumps air into the air cylinder 66 through the hose 62. The air in the air cylinder 66 enters the rotating drum 68 through the rotating joint 67. The air in the rotating drum 68 is blown toward the grinding wheel 43 through the air blowing transverse tube 69, which can cool the grinding wheel 43 and also blow away the debris on the grinding wheel 43.

[0035] The planetary gear follower assembly includes a prism 2 610, a follower rotary rod 611 and a prismatic hole 612. The top of the rotating cylinder 68 is fixedly connected to the bottom of the prism 2 610. The left and right ends of the follower rotary rod 611 are respectively rotatably connected to the outer peripheral sides of the bottom ends of the two planetary rotating cylinders 27 through bearings. The middle of the follower rotary rod 611 is provided with a prismatic hole 612 that corresponds to the top of the prism 2 610. Since the two ends of the follower rotary rod 611 are rotatably connected to the two planetary rotating cylinders 27, the follower rotary rod 611 rotates synchronously with the planetary rotary rod 26. When the lifting assembly drives the lifting plate 65 to rise, the prism 2 610 rises and is inserted into the prismatic hole 612 in the middle of the follower rotary rod 611. In order to prevent the rotating cylinder 68 from rotating uncontrollably relative to the cylinder 66 when the prism 2 610 is not inserted into the prismatic hole 612, a friction positioning assembly can be provided to connect the lifting plate 65 and the rotating cylinder 68, so that the prism 2 610 and the prismatic hole 612 are disengaged. After that, the rotating drum 68 cannot rotate freely. When the prism 2 610 rises next time, it can still be aligned and inserted into the prismatic hole 612. After the grinding of the bearing ring 7 is completed, the lifting assembly drives the lifting plate 65 to descend, and the top of the prism 2 610 is separated from the prismatic hole 612 until the top of the prism 2 610 is flush with the upper side of the bearing ring 7. At this time, it is convenient to take out the grinding bearing ring 7, avoiding the height of the prism 2 610 being too high to affect the unloading operation of the bearing ring 7. The loading and unloading operations of the bearing ring 7 can be completed by a robot.

[0036] The friction positioning assembly includes a mounting frame 613, a radial slide bar 614, a spring 615, and a friction arc plate 616. The side of the lifting plate 65 is fixedly connected to the mounting frame 613, and the radial slide bar 614 is slidably connected in the horizontal sliding hole on the top of the mounting frame 613. The radial slide bar 614 is distributed radially along the rotating drum 68, and the end of the radial slide bar 614 close to the rotating drum 68 is fixedly connected to the friction arc plate 616. The rod section of the radial slide bar 614 located between the friction arc plate 616 and the mounting frame 613 is sleeved with a spring 615. The spring 615 pushes the friction arc plate 616 to fit tightly against the outside of the rotating drum 68. The friction arc plate 616 provides friction for the rotation of the rotating drum 68 to prevent the uncontrolled free rotation of the rotating drum 68 after the prism 2 610 is separated from the prismatic hole 612. The friction arc plate 616 needs to be made of wear-resistant material.

[0037] It is worth noting that the power motor 211, the swing electric telescopic rod 33, the pull-up electric telescopic rod 36, the electromagnet 37, the clamping motor 511, the air pump 61, and the lifting electric telescopic rod 64 disclosed in the above embodiments are all controlled by an external PLC controller, and the control method thereof adopts the method commonly used in the prior art. The power motor 211 and the clamping motor 511 both adopt servo motors, and each time the power motor 211 stops working, the planetary rotating rod 26 needs to be set horizontally. At this time, the two swing electric telescopic rods 33 correspond to the two swing cylinders 32 respectively, and the two electromagnets 37 also correspond to the two iron blocks 39 respectively.

[0038] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
