[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0019] In order to facilitate the stacking and sorting of unqualified ring parts after they are discharged, as an embodiment of the present invention, Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a device and method for detecting the corrugation wave number of a rolling bearing described in the present invention include a support 1, a detection mechanism is arranged on the top of the support 1, the detection mechanism includes a detection unit, a conveying unit, a discharge unit and a stacking unit, the detection unit is used for corrugation detection of annular workpieces, the conveying unit is used for conveying and moving the annular workpieces, the discharge unit is used for discharging the pile of unqualified annular workpieces, and the stacking unit is used for stacking and sorting the unqualified annular workpieces.

[0020] When in use, the conveying unit is used to drive the annular workpiece to move to the detection structure, and the detection structure is used to perform outer ring waviness detection, inner ring waviness detection and horizontality detection on the annular workpiece, thereby facilitating the detection of the annular workpiece and improving the convenience and efficiency of the detection. After the detection structure completes the detection of the annular workpiece, the conveying unit is used to move the inspected annular workpiece again, and the conveying unit is used to transport qualified annular workpieces to designated positions, while transporting unqualified annular workpieces to the discharge unit. When the number of unqualified annular workpieces on the discharge unit reaches a certain amount, the discharge unit is driven to move. After the discharge unit moves a certain distance, the stacking unit is used to stack the annular workpieces placed on the discharge unit onto the stacking unit, without the need for manual stacking and sorting, thereby improving the convenience of handling annular workpieces and processing efficiency.

[0021] In order to facilitate the palletizing of unqualified ring-type workpieces, for example, Figure 1 , Figure 2 , Figure 4 As shown, the present invention also includes that the stacking unit includes two groups of symmetrically arranged discharge boxes 2, the discharge boxes 2 are located on one side of the discharge unit, and the side of the discharge box 2 close to the discharge unit is provided with an opening 3 that is arranged through, and a lifting structure and a driving structure are provided inside the discharge box 2, and the driving structure is used to drive the lifting structure to move up and down, and a mobile aggregate structure is provided inside the discharge box 2, and when the lifting structure moves downward, it drives the mobile aggregate structure to move.

[0022] When in use, when the number of unqualified annular workpieces on the discharge unit reaches a certain amount, the discharge unit is driven to move. After the discharge unit moves a certain distance, the discharge unit moves into the discharge box 2 through the opening 3. When the discharge unit moves, it drives the driving structure to work, and relies on the driving structure to drive the lifting structure to move upward. When the lifting structure moves upward a certain distance, the lifting structure contacts the annular workpiece placed on the discharge unit, and drives the annular workpiece to move upward, so that the annular workpiece is no longer in contact with the discharge unit. At this time, the discharge unit is driven to reset and move. When the discharge unit resets and moves, the lifting structure is driven downward by the driving structure. When the lifting structure moves downward a certain distance, the annular workpiece placed on the lifting structure contacts the upper surface of the mobile aggregate structure, so as to facilitate the stacking of unqualified annular workpieces. When the discharge unit is reset and moved to the initial position, the transport unit can place the unqualified ring-shaped workpiece on the discharge unit again, thereby improving the convenience of use.

[0023] In order to facilitate the movement of unqualified ring-type workpieces, for example, Figure 1 , Figure 2 , Figure 3 , as shown, the present invention also includes that the discharge unit includes a fixed plate 4 horizontally installed on the upper surface of the support 1, and the upper surface of the fixed plate 4 is slidably connected with two groups of symmetrically arranged L-shaped push plates 5, and the upper surfaces of the L-shaped push plates 5 are fixedly connected with storage rods 6 for stacking ring workpieces, and one side of the L-shaped push plates 5 is provided with a first sensor 7, and the first sensor 7 is fixed to the side of the storage rod 6 through a mounting plate, and the side of the L-shaped push plates 5 away from the storage rod 6 is provided with a horizontally arranged push cylinder 8, the fixed end of the push cylinder 8 is fixedly connected to the upper surface of the support 1, and the output end of the push cylinder 8 is fixedly connected to one side of the L-shaped push plate 5.

[0024] When in use, the unqualified annular workpieces are transported to the storage rod 6 by relying on the transport unit, and the annular workpieces on the upper part of the storage rod 6 are detected by relying on the first sensor 7. When the annular workpieces on the storage rod 6 reach a certain number, the pushing cylinder 8 drives the L-shaped pushing plate 5 to move. When the L-shaped pushing plate 5 moves, it drives the annular workpieces to move synchronously into the stacking unit. The stacking unit stacks the annular workpieces on the storage rod 6. When the annular workpieces on the storage rod 6 are separated from the storage rod 6, the pushing cylinder 8 drives the L-shaped pushing plate 5 to reset and move to the initial state, so as to facilitate the subsequent placement of unqualified annular workpieces on the storage rod 6.

[0025] In order to facilitate the separation of the ring-like workpiece from the storage rod 6, for example, Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 As shown, the present invention also includes that the lifting structure includes a threaded rod 9 vertically installed inside the discharge box 2, both ends of the threaded rod 9 are rotatably connected with a connecting rod 10, one end of the connecting rod 10 is fixedly connected to the inner wall of the discharge box 2, a moving block 11 is threadedly connected to the threaded rod 9, and two groups of support rods 12 are fixedly connected to the lower surface of the moving block 11, and the lower ends of the support rods 12 are fixedly connected to horizontally arranged lifting rods 13, and the upper edges of the two groups of lifting rods 13 that are close to each other are provided with a limiting groove 14, and the lifting rod 13 is provided with a wedge surface 15 on the side away from the support rod 12; A vertical positioning groove 16 is provided on the inner wall of the discharge box 2 , and a positioning block 17 corresponding to the positioning groove 16 is fixedly connected to one side of the moving block 11 . The positioning block 17 is located in the positioning groove 16 and is slidably connected to the positioning groove 16 .

[0026] When in use, when the unqualified annular workpieces on the discharge unit reach a certain amount, the discharge unit is driven to move through the opening 3 and move into the discharge box 2. The driving structure is driven to work when the discharge unit moves, and the threaded rod 9 is driven to rotate by the driving structure. When the threaded rod 9 rotates, the moving block 11, the support rod 12 and the lifting rod 13 are driven to move upward synchronously. When the moving block 11 moves up a certain distance, the driving structure no longer drives the threaded rod 9 to rotate. As the pushing cylinder 8 continues to drive the L-shaped pushing plate 5 to move, the annular workpiece located at the bottom of the storage rod 6 is squeezed and contacted with one end of the two groups of lifting rods 13, and the wedge-shaped surface 15 is used to move the annular workpiece to the limiting groove 14 on the lifting rod 13. As the L-shaped pushing plate 5 continues to move, the threaded rod 9 is driven to rotate again at this time. When the threaded rod 9 rotates, the lifting rod 13 is driven to move upward. When the lifting rod 13 moves upward, it drives the annular workpiece to move upward synchronously, so that the annular workpiece is separated from the storage rod 6; When the annular workpiece is separated from the storage rod 6, the push cylinder 8 drives the L-shaped push plate 5 to reset and move. When the L-shaped push plate 5 resets and moves a certain distance, the storage rod 6 is no longer located below the lifting rod 13. As the L-shaped push plate 5 continues to reset and move, the driving structure is driven to work, and the driving structure drives the threaded rod 9 to rotate in the opposite direction. When the threaded rod 9 rotates in the opposite direction, the moving block 11, the support rod 12 and the lifting rod 13 are driven to move downward synchronously. When the lifting rod 13 moves downward a certain distance, the annular workpiece placed on the lifting rod 13 contacts the moving aggregate structure, so as to facilitate the stacking of the annular workpieces and improve the processing efficiency and convenience of use. The positioning block 17 and the positioning groove 16 can prevent the threaded rod 9 from rotating and driving the moving block 11 to rotate synchronously, thereby ensuring the stability of the moving block 11.

[0027] In order to facilitate the movement of the moving block 11, for example, Figure 4 , Figure 6 , Figure 7 , Figure 8 , Fig.11 , Fig.12As shown, the present invention also includes that the driving structure includes a first driving rod 18 and a second driving rod 19 arranged vertically, the first driving rod 18 is located on one side of the discharge box 2 close to the L-shaped push plate 5, both ends of the first driving rod 18 are rotatably connected to a first horizontally arranged fixed rod 20, the first fixed rod 20 is fixedly connected to the inner wall of the discharge box 2, the lower end of the first driving rod 18 is fixedly connected to a first gear 21, the upper end of the first driving rod 18 is fixedly connected to a first pulley 22, the upper end of the threaded rod 9 is fixedly connected to a second pulley 23, and the first pulley 22 and the second pulley 23 are transmitted through a first transmission belt 24; The second driving rod 19 is located on the side of the first driving rod 18 away from the L-shaped pushing plate 5, the upper end of the second driving rod 19 is fixedly connected to the second gear 25, the first gear 21 and the second gear 25 are both located in the moving direction of the L-shaped pushing plate 5, the lower end of the second driving rod 19 is rotatably connected to a horizontally arranged second fixed rod 26, the second fixed rod 26 is fixedly connected to the inside of the discharge box 2, the lower end of the second driving rod 19 is fixedly connected to a third pulley 27, the lower end of the threaded rod 9 is fixedly connected to a fourth pulley 28, and the third pulley 27 and the fourth pulley 28 are transmitted through a second transmission belt 29; A horizontally arranged slide groove 30 is provided on one side of the L-shaped push plate 5, and a rack 31 is slidably connected in the slide groove 30. When the L-shaped push plate 5 moves toward the discharge box 2, the rack 31 meshes with the first gear 21 and the second gear 25 respectively for transmission.

[0028] During use, when the number of unqualified annular workpieces on the discharge unit reaches a certain amount, the discharge unit is driven to move through the opening 3 and into the discharge box 2. After the discharge unit moves a certain distance, the rack 31 on one side of the L-shaped push plate 5 meshes with the first gear 21 for transmission, and drives the first gear 21 and the first driving rod 18 to rotate. When the first driving rod 18 rotates, it relies on the first pulley 22 and the first transmission belt 24 to drive the second pulley 23 to rotate synchronously. When the second pulley 23 rotates, it drives the threaded rod 9 to rotate. When the threaded rod 9 rotates, it drives the moving block 11 to move up. When the moving block 11 moves up a certain distance, the rack 31 is no longer meshed with the first gear 21 for transmission, so as to no longer drive the threaded rod 9 to rotate. , as the push cylinder 8 continues to drive the L-shaped push plate 5 to move, the annular workpiece located at the bottom of the storage rod 6 is squeezed and contacted with one end of the two sets of lifting rods 13, and the annular workpiece is moved into the limiting groove 14 on the lifting rod 13 by relying on the wedge surface 15. As the L-shaped push plate 5 continues to move, the rack 31 is meshed with the second gear 25 for transmission, and drives the second gear 25, the second drive rod 19 and the third pulley 27 to rotate. When the third pulley 27 rotates, it relies on the second transmission belt 29 and the fourth pulley 28 to drive the threaded rod 9 to rotate. When the threaded rod 9 rotates, it drives the lifting rod 13 to move up. When the lifting rod 13 moves up, it drives the annular workpiece to move up synchronously, so that the annular workpiece is separated from the storage rod 6; When the annular workpiece is separated from the storage rod 6, the pushing cylinder 8 drives the L-shaped pushing plate 5 to reset and move. When the L-shaped pushing plate 5 resets and moves, the rack 31 slides in the slide groove 30. When the L-shaped pushing plate 5 moves a certain distance, the storage rod 6 is no longer located below the lifting rod 13. As the L-shaped pushing plate 5 continues to reset and move, one end of the rack 31 contacts one end of the slide groove 30. At the same time, the rack 31 is meshed with the second gear 25 to drive the threaded rod 9 to rotate in the opposite direction. When the threaded rod 9 rotates in the opposite direction, it drives the moving block 11 and the support The support rod 12 and the lifting rod 13 move downward synchronously. When the L-shaped push plate 5 is reset and moved a certain distance, the rack 31 is no longer engaged with the second gear 25 for transmission. As the L-shaped push plate 5 continues to reset and move, the rack 31 is engaged with the first gear 21 for transmission, and continues to drive the threaded rod 9 to rotate in the opposite direction, while driving the moving block 11 to move downward. When the lifting rod 13 moves downward a certain distance, the annular workpieces placed on the lifting rod 13 are in contact with the moving aggregate structure, which facilitates the stacking of the annular workpieces and improves processing efficiency and ease of use.

[0029] For example, Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11As shown, the present invention also includes that the mobile aggregate structure includes a discharge port 32, the discharge port 32 is located on the side of the discharge box 2 away from the L-shaped push plate 5, a horizontally arranged support plate 33 is provided in the discharge port 32, and the inner wall of the discharge box 2 is provided with a symmetrically arranged moving groove, the two sides of the support plate 33 are located in the moving groove and are slidably connected to the moving groove, a support plate 34 is placed on the support plate 33, and the upper surface of the support plate 34 is connected to a trapezoidal top plate 35 with a small upper part and a large lower part, and the trapezoidal top plate 35 is located between the bottoms of the two groups of lifting rods 13; The outer side of the discharge box 2 is provided with a first horizontally arranged pneumatic telescopic rod 36, the fixed end of the first pneumatic telescopic rod 36 is fixedly connected to the discharge box 2, the output end of the first pneumatic telescopic rod 36 passes through the discharge box 2 and is fixedly connected to a vertically arranged moving rod 37, the upper end of the moving rod 37 is fixedly connected to the lower surface of the support plate 33, the fixed end of the first pneumatic telescopic rod 36 is connected to a regulating valve 38, and the inside of the discharge box 2 is fixedly connected with a vertically arranged second pneumatic telescopic rod 39, the second pneumatic telescopic rod 39 is located above the support plate 33, and the bottom of the fixed end of the second pneumatic telescopic rod 39 is connected to the discharge box 2. The cross bar 40 is fixedly connected to the inner wall of the discharge box 2. After the moving block 11 moves downward, it is squeezed and contacted with the output end of the second pneumatic telescopic rod 39. The lower surface of the cross bar 40 is fixedly connected with a joint 41 connected to the fixed end of the second pneumatic telescopic rod 39. The joint 41 is connected to the regulating valve 38 through a pipeline. After the second pneumatic telescopic rod 39 is compressed, the gas in the second pneumatic telescopic rod 39 slowly enters the first pneumatic telescopic rod 36 through the regulating valve 38. One side of the second pneumatic telescopic rod 39 is connected to a one-way air inlet valve for air intake, and the pipeline between the joint 41 and the regulating valve 38 is connected to a one-way air outlet valve.

[0030] When in use, the rack 31 meshes with the first gear 21 when the L-shaped push plate 5 continues to reset and move, and drives the threaded rod 9 to rotate in the opposite direction, and at the same time drives the moving block 11 to move downward. When the moving block 11 moves down a certain distance, it squeezes the output end of the second pneumatic telescopic rod 39, and the second pneumatic telescopic rod 39 is connected to the first pneumatic telescopic rod 36 by means of a pipeline. When the lifting rod 13 moves down a certain distance, the ring-like workpiece placed on the lifting rod 13 contacts the upper surface of the trapezoidal top plate 35, so as to facilitate the lifting of the ring-like workpiece. The ring-shaped workpieces are stacked on the trapezoidal ejector plate 35, and the regulating valve 38 is used to ensure that the output end of the second pneumatic telescopic rod 39 is slowly extended. When the output end of the second pneumatic telescopic rod 39 is extended, the support plate 33, the support plate 34 and the trapezoidal ejector plate 35 are driven to move. When the support plate 33 moves a certain distance, the ring-shaped workpieces on the trapezoidal ejector plate 35 are synchronously moved a certain distance. At this time, the ring-shaped workpieces are no longer located under the lifting rod 13, so as to facilitate the subsequent stacking of unqualified ring-shaped workpieces, improve processing efficiency and convenience of use; The moving groove can improve the movement stability of the support plate 33; when the number of annular workpieces placed on the trapezoidal top plate 35 reaches a certain amount, the support plate 34 is taken out and the next group of support plates 34 is placed on the support plate 33, so as to facilitate the subsequent stacking of the annular workpieces.

[0031] In order to facilitate the waviness detection of ring-type workpieces, for example, Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the present invention also includes that the detection unit includes an air spindle 42 installed above the support 1, a detection sliding seat 43 is provided on one side of the air spindle 42, and an outer ring corrugation probe 44, an inner ring corrugation probe 45 and a second sensor 50 are provided in the detection sliding seat 43.

[0032] When in use, the ring-like workpiece to be inspected is placed on the air spindle 42 by relying on the transport unit, and the air spindle 42 is driven to rotate stably. Then, the outer ring corrugation probe 44, the inner ring corrugation probe 45 and the second sensor 50 provided in the detection sliding seat 43 are used to perform outer ring corrugation inspection, inner ring corrugation inspection and horizontality inspection on the ring-like workpiece.

[0033] In order to facilitate the movement of the ring-type workpiece, for example, Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the present invention also includes that the transport unit includes a transport base 46, a four-axis robot arm 47 is provided above the transport base 46, a transport plate seat 48 is connected below one end of the four-axis robot arm 47, and a gripper cylinder 49 is connected to the lower surface of the transport plate seat 48.

[0034] When in use, the four-axis robot arm 47 can drive the annular workpieces to move, and the two clamping cylinders 49 can clamp and fix two groups of annular workpieces at the same time, and drive the annular workpieces to move, and move the annular workpieces to the air spindle 42 for inspection. After the inspection is completed, the clamping cylinders 49 are used again to drive the inspected annular workpieces to move, and qualified annular workpieces are moved to the specified position, and unqualified annular workpieces are moved to the storage rod 6, so as to facilitate subsequent processing.

[0035] For example, Figure 2 As shown, the present invention also includes that a conveying plate 51 for conveying ring-like workpieces is provided on one side of the support 1.

[0036] When in use, the conveying plate 51 is used to drive the annular workpiece to move, thereby improving the convenience of conveying the annular workpiece.

[0037] A method for detecting the wave number of rolling bearing waviness adopts the above-mentioned device for detecting the wave number of rolling bearing waviness, and specifically comprises the following steps: S1. Rely on the handling unit to move the ring-shaped workpiece to the detection structure; S2. Rely on the detection structure to detect the ring-type workpiece; S3, when the detection structure completes the detection of the ring-like workpiece, the detection completed ring-like workpiece is moved again by the transport unit, and the qualified ring-like workpiece is transported to the designated position by the transport unit, and the unqualified ring-like workpiece is transported to the discharge unit; S4. When the number of unqualified annular workpieces on the discharge unit reaches a certain amount, the discharge unit is driven to move. After the discharge unit moves a certain distance, the annular workpieces placed on the discharge unit are stacked on the stacking unit by the stacking unit.

[0038] When the present invention is in use, the four-axis robot 47 drives the ring-like workpiece to move, and the two clamping claw cylinders 49 can clamp and fix two groups of ring-like workpieces at the same time, and drive the ring-like workpieces to move, and move the ring-like workpieces to the air spindle 42, drive the air spindle 42 to rotate stably, and then rely on the outer ring corrugation probe 44, the inner ring corrugation probe 45 and the second sensor 50 provided in the detection sliding seat 43 to perform outer ring corrugation detection, inner ring corrugation detection and horizontality detection on the ring-like workpiece; After the inspection is completed, the clamping cylinder 49 is used again to drive the ring-like workpieces that have been inspected to move, and the qualified ring-like workpieces are moved to the designated position, and the unqualified ring-like workpieces are moved to the storage rod 6, so as to facilitate the subsequent processing thereof; The annular workpieces on the upper part of the storage rod 6 are detected by the first sensor 7. When the annular workpieces on the storage rod 6 reach a certain number, the push cylinder 8 drives the L-shaped push plate 5 to move, and the L-shaped push plate 5 moves into the discharge box 2 through the opening 3. After the L-shaped push plate 5 moves a certain distance, the rack 31 on one side of the L-shaped push plate 5 meshes with the first gear 21 for transmission, and drives the first gear 21 and the first driving rod 18 to rotate. When the first driving rod 18 rotates, it relies on the first pulley 22 and the first transmission belt 24 to drive the second pulley 23 to rotate synchronously. When the second pulley 23 rotates, it drives the threaded rod 9 to rotate. When the threaded rod 9 rotates, it drives the moving block 11 to move up. When the moving block 11 moves up a certain distance, the rack 31 is no longer engaged with the first gear 2 1 meshing transmission, so that the threaded rod 9 is no longer driven to rotate. As the push cylinder 8 continues to drive the L-shaped push plate 5 to move, the annular workpiece located at the bottom of the storage rod 6 is squeezed and contacted with one end of the two sets of lifting rods 13, and the annular workpiece is moved into the limiting groove 14 on the lifting rod 13 by relying on the wedge surface 15. As the L-shaped push plate 5 continues to move, the rack 31 is meshed and transmitted with the second gear 25, and drives the second gear 25, the second driving rod 19 and the third pulley 27 to rotate. When the third pulley 27 rotates, it relies on the second transmission belt 29 and the fourth pulley 28 to drive the threaded rod 9 to rotate. When the threaded rod 9 rotates, it drives the lifting rod 13 to move up. When the lifting rod 13 moves up, it drives the annular workpiece to move up synchronously, so that the annular workpiece is separated from the storage rod 6; When the annular workpiece is separated from the storage rod 6, the pushing cylinder 8 drives the L-shaped pushing plate 5 to reset and move. When the L-shaped pushing plate 5 resets and moves, the rack 31 slides in the slide groove 30. When the L-shaped pushing plate 5 moves a certain distance, the storage rod 6 is no longer located below the lifting rod 13. As the L-shaped pushing plate 5 continues to reset and move, one end of the rack 31 contacts one end of the slide groove 30. At the same time, the rack 31 is engaged with the second gear 25 to drive the threaded rod 9 to rotate in the opposite direction. When the threaded rod 9 rotates in the opposite direction, it drives the moving block 11, the support rod 12 and the lifting rod 13 to move downward synchronously. When the L-shaped pushing plate 5 resets and moves a certain distance, the rack 31 is no longer engaged with the second gear 25 for transmission. As the L-shaped pushing plate 5 continues to reset and move, the rack 31 is engaged with the first gear 21 for transmission, and continues to drive the threaded rod 9 to rotate in the opposite direction, while driving the moving block 1 1 moves downward, when the moving block 11 moves downward a certain distance and squeezes the output end of the second pneumatic telescopic rod 39, the second pneumatic telescopic rod 39 is connected to the first pneumatic telescopic rod 36 by means of a pipeline, and when the lifting rod 13 moves downward a certain distance, the annular workpiece placed on the lifting rod 13 is in contact with the upper surface of the trapezoidal ejecting plate 35, so as to facilitate the stacking of the annular workpiece on the trapezoidal ejecting plate 35, and at the same time, the regulating valve 38 is relied on to ensure that the output end of the second pneumatic telescopic rod 39 is slowly extended, and when the output end of the second pneumatic telescopic rod 39 is extended, it drives the support plate 33, the supporting plate 34 and the trapezoidal ejecting plate 35 to move. When the support plate 33 moves a certain distance, the annular workpiece on the trapezoidal ejecting plate 35 is synchronously moved a certain distance, and the annular workpiece is no longer located below the lifting rod 13, so as to facilitate the subsequent stacking of unqualified annular workpieces, thereby improving processing efficiency and convenience of use.
