[0024] like Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 5 The inner ring is transported to the separation component through the conveying track 15, and multiple inner rings are separated and transported to the connecting groove 9 one by one by the separation component. At this time, the inner ring will roll from the connecting groove 9 to the feeding groove 8 and contact the bottom groove wall of the feeding groove 8. The push plate 12 is located on the side of the inner ring away from the expansion positioning shaft 4, and then the loading plate 7 is driven by the moving part to move vertically downward until the feeding groove 8 is aligned with the expansion positioning shaft 4, and the moving part stops working.

A second electric cylinder 19 for pushing the vertical end of the top plate 18 is arranged between the two connecting plates 17. The purpose of this arrangement is that when it is necessary to drive the loading plate 7 to move vertically, it is only necessary to open the second electric cylinder 19. At this time, the piston rod of the second electric cylinder 19 will push the top plate 18 to drive the slide plate 16 to move vertically. At this time, the loading plate 7 will follow the slide plate 16 to move vertically, which is simple and convenient to use.

[0026] like Figure 1 and Figure 4 and Figure 5 The partition assembly includes a bottom plate 20 which is obliquely arranged on the side of the mounting plate 13 away from the fixed plate 5, and two opposite side plates 21 are arranged on the upper surface of the bottom plate 20, and the bottom plate 20 and the two side plates 21 form a transition track 22, and the bottom end of the transition track 22 is close to the connecting groove 9. The conveying track 15 is used to convey the inner ring to the transition track 22. A protrusion 23 is arranged on the top of the mounting plate 13, and a rotating shaft 24 is arranged on the front side of the protrusion 23. A rotating plate 25 is rotatably connected to the rotating shaft 24. Two rotating columns 26 are rotatably connected to the front side of the rotating plate 25, and the two rotating columns 26 are respectively located on the left and right sides of the rotating shaft 24. The bottom ends of the two rotating columns 26 are respectively vertically downwardly provided with a first dividing column 27 and a second dividing column 28 located above the transition track 22. Two opposite horizontal plates 29 are arranged on the front side of the mounting plate 13, and the two horizontal plates 29 The top of each of the two partition columns 27 and the second partition column 28 is provided with a long strip groove 30, and the two long strip grooves 30 correspond to the first partition column 27 and the second partition column 28 respectively, and the bottom ends of the first partition column 27 and the second partition column 28 pass through the long strip groove 30, and the bottom ends of the first partition column 27 and the second partition column 28 are flush, the first partition column 27 is located at the right end of the front side of the rotating plate 25, and the second partition column 28 is located at the left end of the front side of the rotating plate 25. The bottom end of the first partition column 27 is located in the transition track 22 and contacts with the upper left side of the outer wall of the inner ring in the transition track 22. A fixing ring 31 located above the horizontal plate 29 is fixedly connected to the second partition column 28, and a compression spring 32 is provided between the fixing ring 31 and the horizontal plate 29.

At this time, the inner ring on the transition track 22 can be blocked by the first partition column 27. When it is necessary to convey the first inner ring to the communication groove 9, only need to make the feeding plate 7 move vertically downward through the moving member until the feeding groove 8 is aligned with the expansion positioning shaft 4. At this time, the vertical column 33 and the pressing plate 34 will move downward along with the feeding plate 7 through the top plate 18. When the feeding groove 8 is aligned with the expansion positioning shaft 4, the pressing plate 34 will contact and press the upper left side of the rotating plate 25, causing the rotating plate 25 to rotate on the rotating shaft 24. At this time, the compression spring 32 is compressed, and the rotating plate 25 drives the second partition column 28 to move downward through the rotating column 26, and the first partition column 27 moves upward. At this time, the first partition column 27 will release the block on the first inner ring, and the inner ring on the transition track 22 will roll in the direction close to the communication groove 9 under the influence of gravity until the upper left corner of the outer wall of the first inner ring contacts the bottom end of the second partition column. At this time, the first inner ring will be located between the first partition column 27 and the second partition column 28; Then, make the feeding plate 7 move vertically upward back to its original position through the moving member. The pressing plate 34 is separated from the rotating plate 25, and the compressed compression spring 32 pushes the rotating plate 25 to rotate reversely to its original position. At this time, the rotating plate 25 drives the second partition column 28 to move upward through the rotating column 26, and the first partition column 27 moves downward. At this time, the second partition column 28 will release the block on the first inner ring, and the bottom end of the first partition column will be inserted between the first inner ring and the second inner ring and contact the upper left corner of the outer wall of the second inner ring. At this time, the first inner ring on the transition track 22 will continue to roll in the direction close to the communication groove 9 under the influence of gravity, while the remaining inner rings will stop rolling under the block of the first partition column 27. Through the above process, by moving the feeding plate 7 up and down, the second partition column 28 and the first partition column 27 perform alternating up and down displacements, so that multiple inner rings on the transition track 22 can be released one by one. When the feeding plate 7 moves downward first and then moves back to its original position to complete a round trip movement, one inner ring on the transition track 22 is released, which is simple and convenient to use.

The bottom end of the first slider 54 is provided with an L-shaped cantilever 55, and a reverse U-shaped pushing plate 56 is provided on one side of the bottom end of the cantilever 55 away from the first slider 54. One end of the expansion positioning shaft 4 passes through the pushing plate 56, and the inner ring on the expansion positioning shaft 4 is located on the side of the pushing plate 56 away from the chassis 2. A fourth electric cylinder 57 for pushing the first slider 54 to slide in a direction away from or close to the chassis 2 is provided on the vertical plate 6.

[0030] As Figure 1 and Figure 2 and Figure 3and Figure 6 , when the inner ring processing on the expansion and positioning shaft 4 is completed, the slide 37 on the first slide rail 35 and the second slide rail 36 is moved back to the original position in the direction away from the expansion and positioning shaft 4 through the third electric cylinder 40, and the third electric cylinder 40 stops working, and then the first motor 47 is turned on, and the rotating shaft of the first motor 47 drives the gear 48 to rotate, and the gear 48 drives the blanking plate 41 to move in the direction close to the expansion and positioning shaft 4 through the rack 46 meshing therewith. When it moves to a suitable position, the fourth electric cylinder 57 is turned on, and the piston rod of the fourth electric cylinder 57 pushes the first slider 54 to drive the cantilever 55 away from the chassis 2. At this time, the push plate 56 will move with the cantilever 55, and the expansion and positioning shaft can be pushed by the push plate 56 4 is pushed to the receiving column 49 of the blanking plate 41, and then the rotating shaft of the first motor 47 drives the gear 48 to rotate in the opposite direction, so that the blanking plate 41, the receiving column 49 and the inner ring on the receiving column 49 are away from the expansion positioning shaft 4. At this time, the receiving column 49 and the inner ring are close to the baffle 52 until the receiving column 49 passes through the baffle 52. In the process of the receiving column 49 passing through the baffle 52, the baffle 52 will contact one side of the inner ring on the receiving column 49, and as the receiving column 49 passes through the baffle 52, the inner ring is pushed down from the receiving column 49. At this time, the pushed down inner ring will fall to the blanking track 51, and then roll along the blanking track 51 for blanking, without manual blanking, and the blanking is simple and convenient.

[0031] like Figure 1 and Figure 2 and Figure 3 and Figure 6 The receiving column 49 is rotatably connected to the blanking plate 41, and the detection component includes a mounting groove 58 arranged at the bottom end of the blanking plate 41 near the receiving column 49. A second sliding groove 59 connected to the mounting groove 58 is vertically arranged on the side of the blanking plate 41 near the receiving column 49, and a second slider 60 is vertically slidably connected in the second sliding groove 59. A vertical rod 61 is vertically upwardly arranged on the side of the second slider 60 near the mounting groove 58, and the top of the vertical rod 61 passes through the blanking plate 41 and extends out of the mounting groove 58. A digital dial gauge 62 is provided through the adjusting member, and the digital dial gauge 62 is located just above the receiving column 49. The second slider 60 is rotatably connected to a driving column 63 located just below the receiving column 49 on the side away from the vertical rod 61. A second motor 64 for driving the driving column 63 to rotate is provided on the vertical rod 61. The second motor 64 is located in the mounting groove 58. A push block 65 located above the second motor 64 is horizontally provided on the vertical rod 61. A fifth electric cylinder 66 for pushing the push block 65 to move vertically is provided on the blanking plate 41. At the top of the base 1, a collection box 68 is provided through a placement rack 67, and the collection box 68 is located at the rear side of the blanking track 51. On one side of the outer wall of the collection box 68, a suspension plate 69 is provided, and a vertical column 70 is rotatably connected to the suspension plate 69. Along the vertical direction of the vertical column 70 on the vertical column 70, an intercepting plate 71 is provided. On the suspension plate 69, a third motor 72 for driving the vertical column 70 to rotate is provided. A placement plate 73 is placed at the bottom of the collection box 68, and a weighing sensor 74 is provided between the placement plate 73 and the bottom of the collection box 68. At the top of the fixed table 43, a controller 75 and an alarm lamp 76 are provided. The alarm lamp 76, the digital display micrometer 62, and the third motor 72 are all electrically connected to the controller 75.

[0032] As Figure 1 and Figure 2 and Figure 3 and Figure 6 When the inner ring on the expansion positioning shaft 4 is pushed onto the receiving post 49 of the blanking plate 41 by the pushing member, both the receiving post 49 and the driving post 63 are located within the inner ring, and the digital display micrometer 62 is located above the inner ring. At this time, the fifth electric cylinder 66 is opened, and the piston rod of the fifth electric cylinder 66 pushes the push block 65 to drive the vertical rod 61 to move downward. At this time, the second slider 60, the adjusting member, and the digital display micrometer 62 move along with the vertical rod 61 until the driving post 63 on the second slider 60 abuts against the bottom end of the inner wall of the inner ring. At this time, the detection end of the digital display micrometer 62 will extend into the groove on the inner ring and contact the groove. Then, the second motor 64 is opened, and the driving post 63 is driven to rotate by the rotating shaft of the second motor 64. At this time, the driving post 63 will drive the inner ring to rotate. At this time, the concentricity of the groove and the inner ring of the rotating inner ring can be detected through the digital display micrometer 62. By measuring the radial runout at different positions of the groove through the digital display micrometer 62, it is required that the runout ≤ a certain value to be qualified. For example, ≤ 0.03 mm; During the detection process, the blanking plate 41, the receiving post 49, and the inner ring on the receiving post 49 move away from the expansion positioning shaft 4. When the receiving post 49 moves above the collection box 68, the detection is completed. When the detection result is qualified, the receiving post 49 and the inner ring on the receiving post 49 will pass above the collection box 68. At this time, the intercepting plate 71 is parallel to the blanking plate 41; When the radial runout measured by the digital display micrometer 62 at different positions of the groove is greater than 0.03 mm, the detection result is unqualified at this time. The digital display micrometer 62 sends a signal to the controller 75, and the controller 75 controls the alarm lamp 76 to work and issue an alarm once. At the same time, it controls the third motor 72 to work. The rotating shaft of the third motor 72 drives the column 70 to rotate counterclockwise by 90 degrees, so that the intercepting plate 71 rotates above the mouth of the collection box 68. At this time, the included angle between the blanking plate 41 and the intercepting plate 71 is 90 degrees. Then the third motor 72 stops working. Then, as the blanking plate 41, the receiving column 49, and the inner ring on the receiving column 49 move away from the expansion positioning shaft 4, the inner ring on the receiving column 49 will contact one side of the intercepting plate 71, and the inner ring on the receiving column 49 will be pushed down by the intercepting plate 71. At this time, the unqualified inner ring will fall onto the placement plate 73 in the collection box 68; When processing a batch of inner rings, for example, when there are five unqualified inner rings in a batch of inner rings, the total weight of the five inner rings is D. The weight of the inner rings on the placement plate 73 is weighed by the weighing sensor 74 below the placement plate 73. When the weight is greater than D, it means that there are more than five unqualified inner rings. At this time, the weighing sensor 74 controls the second electric cylinder 19 in the feeding part to stop working, reducing material waste.

[0033] Such as Figure 6 and Figure 7 For example, the adjusting part includes a T-shaped adjusting plate 77 and an adjusting groove 78 opened on the adjusting plate 77 for the top end of the vertical rod 61 to pass through vertically. The digital display micrometer 62 is arranged at one end of the adjusting plate 77 away from the vertical rod 61. There are two threaded grooves 79 on the adjusting plate 77, and both threaded grooves 79 communicate with the adjusting groove 78 and are respectively located on both sides of the vertical rod 61. Bolts 80 are threadedly connected in both threaded grooves 79, and the ends of the bolts 80 close to the vertical rod 61 are in contact with the vertical rod 61. The purpose of this setting is that by loosening the bolts 80 and then pushing the adjusting plate 77 to move vertically on the vertical rod 61 through the adjusting groove 78, the distance between the digital display micrometer 62 and the drive shaft can be adjusted according to requirements at this time to adapt to inner rings with different outer diameters, which is simple and convenient to use.

[0034] The usage process of this device is as follows: In the first step, the inner rings are conveyed to the transition track 22 through the conveying track 15. At this time, the upper left side of the outer wall of the first inner ring on the transition track 22 will contact the bottom end of the first partition column 27, and the inner rings on the transition track 22 can be blocked by the first partition column 27 at this time.

[0035] The second step is to open the second electric cylinder 19. The piston rod of the second electric cylinder 19 pushes the top plate 18 to drive the slide plate 16 to move vertically downward. At this time, the loading plate 7, the pressure plate 34 and the vertical column 33 will follow the slide plate 16 and the top plate 18 to move downward until the loading trough 8 is aligned with the tightening positioning shaft 4. At this time, the pressure plate 34 will contact the upper left side of the rotating plate 25 and squeeze the rotating plate 25 to rotate on the rotating shaft 24. At this time, the compression spring 32 is compressed, and the rotating plate 25 drives the second partition column 28 to move downward through the rotating column 26, and the first partition column 27 moves upward. At this time, the first partition column 27 will release the obstruction to the first inner ring, and the inner ring on the transition track 22 will be affected by gravity and roll in the direction close to the slide plate 16 until the upper left outer wall of the first inner ring contacts the bottom end of the second partition column 28. At this time, the first inner ring will be located between the first partition column 27 and the second partition column 28.

[0036] The third step is that the piston rod of the second electric cylinder 19 pushes the top plate 18 to drive the slide plate 16 to move vertically upward, so that the loading plate 7 and the pressure plate 34 move vertically upward back to their original positions. When the loading plate 7 moves upward back to its original position, the connecting groove 9 corresponds to the transition track 22, the pressure plate 34 is separated from the rotating plate 25, and the compressed compression spring 32 pushes the rotating plate 25 to rotate in the opposite direction to its original position. The rotating plate 25 rotated to its original position is horizontal. At this time, the rotating plate 25 drives the second dividing column 28 to move upward through the rotating column 26, and the first dividing column 27 moves downward. At this time, the second dividing column 28 will release the obstruction to the first inner ring, and the bottom end of the first dividing column will be inserted between the first inner ring and the second inner ring, and contact with the upper left outer wall of the second inner ring. At this time, the first inner ring on the transition track 22 will continue to roll in the direction close to the connecting groove 9 under the influence of gravity, and the remaining inner rings will be blocked by the first dividing column 27 and stop rolling until the first inner ring rolls from the connecting groove 9 to the loading groove 8.

[0037] In the fourth step, repeat the second step, and in the second step, when the feeding trough 8 is aligned with the tightening and positioning shaft 4, the piston rod of the first electric cylinder 10 pushes the push plate 12 close to the tightening and positioning shaft 4. At this time, the push plate 12 will drive the inner ring in the feeding trough 8 to approach the tightening and positioning shaft 4 until the inner ring is pushed onto the tightening and positioning shaft 4. At this time, the loading is completed. After the loading is completed, repeat the third step and convey the next inner ring to the connecting groove 9. At this time, the next inner ring will roll from the connecting groove 9 to the feeding trough 8. At the same time, open the two third electric cylinders 40, and the piston rod of the third electric cylinder 40 pushes the two slides 37 to slide on the first slide rail 35 and the second slide rail 36 respectively in the direction close to the tightening and positioning shaft 4. At this time, the tool holder 38 and the turning tool 39 will move with the slide 37. At this time, the inner ring on the tightening and positioning shaft 4 can be processed by the turning tool 39.

[0038] Step 5: After the inner ring on the expansion positioning shaft 4 is machined, the third electric cylinder 40 is used to move the sliders 37 on the first slide rail 35 and the second slide rail 36 back to their original positions in a direction away from the expansion positioning shaft 4. Then the third electric cylinder 40 stops working. After that, the first motor 47 is turned on, and the rotating shaft of the first motor 47 drives the gear 48 to rotate. The gear 48 drives the blanking plate 41 to move in a direction closer to the expansion positioning shaft 4 through the rack 46 meshing with it.

[0039] Step 6: After moving to a suitable position, the fourth electric cylinder 57 is turned on. The piston rod of the fourth electric cylinder 57 pushes the first slider 54 to drive the cantilever 55 away from the chassis 2. At this time, the pushing plate 56 will move along with the cantilever 55. At this time, the inner ring on the expansion positioning shaft 4 can be pushed onto the receiving post 49 of the blanking plate 41 through the pushing plate 56. At this time, both the receiving post 49 and the driving post 63 are located inside the inner ring, and the digital display micrometer 62 is located above the inner ring.

[0040] Step 7: The fifth electric cylinder 66 is turned on. The piston rod of the fifth electric cylinder 66 pushes the push block 65 to drive the vertical rod 61 to move downward. At this time, the second slider 60, the adjusting part, and the digital display micrometer 62 move along with the vertical rod 61 until the driving post 63 on the second slider 60 contacts the bottom end of the inner wall of the inner ring. At this time, the detection end of the digital display micrometer 62 will contact the groove on the inner ring. Then the second motor 64 is turned on, and the rotating shaft of the second motor 64 drives the driving post 63 to rotate. At this time, the driving post 63 will drive the inner ring to rotate. At this time, the concentricity of the groove and the inner ring of the rotating inner ring can be detected through the digital display micrometer 62. The radial runout of different positions of the groove is measured by the digital display micrometer 62. It is required that the runout ≤ a certain value is qualified. For example, ≤ 0.03 mm. During the detection process, the rotating shaft of the first motor 47 drives the gear 48 to rotate in the reverse direction, so that the blanking plate 41, the receiving post 49, and the inner ring on the receiving post 49 move away from the expansion positioning shaft 4. At this time, the receiving post 49 and the inner ring approach the baffle 52. When the receiving post 49 moves above the collection box 68, the detection is completed; When the detection result is qualified, the receiving post 49 and the inner ring on the receiving post 49 will pass above the collection box 68. At this time, the intercepting plate 71 is parallel to the blanking plate 41. Then, as the blanking plate 41 moves away from the expansion positioning shaft 4, until the receiving post 49 passes through the baffle 52. During the process of the receiving post 49 passing through the baffle 52, the baffle 52 will contact one side of the inner ring on the receiving post 49 and push the inner ring off the receiving post 49 as the receiving post 49 passes through the baffle 52. At this time, the pushed-off inner ring will fall onto the blanking track 51 and then roll and slide down along the blanking track 51; When the test result is unqualified, the controller 75 controls the alarm lamp 76 to work and give an alarm once. At the same time, it controls the third motor 72 to work. The rotating shaft of the third motor 72 drives the column 70 to rotate counterclockwise by 90 degrees, so that the intercepting plate 71 rotates above the opening of the collection box 68. At this time, the included angle between the blanking plate 41 and the intercepting plate 71 is 90 degrees. Then, as the blanking plate 41, the receiving column 49, and the inner ring on the receiving column 49 move away from the expansion tightening positioning shaft 4, the inner ring on the receiving column 49 will contact one side of the intercepting plate 71, and the inner ring on the receiving column 49 will be pushed down by the intercepting plate 71. At this time, the inner ring will fall onto the placement plate 73 in the collection box 68 for collection, and the concentricity between the groove and the inner ring is manually detected.

[0041] Step 8: After the blanking is completed, just repeat Step 4, Step 5, Step 6, and Step 7 in sequence.

[0042] Embodiment 2: A processing technology according to the above Embodiment 1 includes installing the inner ring on the expansion tightening positioning shaft 4 through the feeding part, then driving the inner ring to rotate by itself by the expansion tightening positioning shaft 4, and then processing a groove on the rotating inner ring through the cutting component. After the processing is completed, the inner ring is removed through the blanking part and the concentricity between the groove and the inner ring is detected by the detection component on the blanking part.
