Description

Technical Field

[0001] This application relates to the technical field of hub bearing processing, and particularly relates to an automatic matching device for hub bearings. Background Art

[0002] The hub bearing is one of the key components of an automobile. Its main function is to bear the weight and provide precise guidance for the rotation of the hub. It needs to bear axial and radial loads, so it is required to have high strength and precise guiding performance.

[0003] In the manufacturing process of the inner and outer rings of the hub bearing, due to the limitations of the accuracy of the manufacturing equipment, whether it is the inner ring or the outer ring, after manufacturing, there will be a certain error in size compared with the standard size. Therefore, after the inner and outer rings are manufactured, it is necessary to measure the sizes of the inner and outer rings (mainly measuring the inner diameter and outer diameter). Through detection, the inner and outer rings with matching sizes are then selected for assembly, so that the assembly error of the hub bearing can be controlled within a reasonable range.

[0004] In the prior art, when measuring the sizes of the inner and outer rings (hereinafter referred to as the target objects), the measurement is mainly carried out by a vernier caliper. This method has low measurement efficiency and is not suitable for large-scale measurement operations. Therefore, in the current industry, a laser diameter gauge is gradually used to detect the sizes of the target objects, which greatly improves the measurement efficiency. However, in actual applications, when the target objects are placed in or taken out of the detection station of the laser diameter gauge, a large amount of manual participation is still required, resulting in insufficient detection efficiency. Therefore, there is an urgent need for an automatic matching device suitable for hub bearings to improve the size detection efficiency of the inner and outer rings and be able to screen out inner and outer rings of different sizes. Summary of the Invention

[0005] In order to improve the detection efficiency of the sizes of the inner and outer rings in the hub bearing, this application provides an automatic matching device for hub bearings.

[0006] The automatic matching device for hub bearings provided by this application adopts the following technical solutions: An automatic matching device for hub bearings, comprising a detection table, a first conveyor belt, a second conveyor belt and a third conveyor belt. A detection device is provided on the detection table, and the first conveyor belt and the second conveyor belt are respectively arranged on both sides of the detection table. The detection table is respectively provided with a first transfer assembly and a second transfer assembly. The first transfer assembly is used to transfer the target object on the first conveyor belt to the detection table, and the second transfer assembly is used to transfer the target object on the detection table to the second conveyor belt. A plurality of third conveyor belts are arranged along the length direction of the second conveyor belt, and the inlet end of each third conveyor belt is connected to the second conveyor belt. A third transfer assembly is provided on the second conveyor belt, and the third transfer assembly is used to push the target object on the second conveyor belt onto the third conveyor belt.

[0007] By adopting the above technical solution, when detecting the size of the target object (inner ring or outer ring), the target object is conveyed to one side of the detection table through the first conveyor belt, and then the target object on the first conveyor belt is transferred to the detection table through the first transfer assembly. The size of the target object can be detected by the detection device. After the detection is completed, the detected target object is transferred to the second conveyor belt through the second transfer assembly. According to the detection result, the target object is pushed onto the designated third conveyor belt through the third transfer assembly, greatly improving the detection efficiency of the overall structure. The setting of a plurality of third conveyor belts can output target objects of different sizes in a classified manner. In practical applications, the inner ring and outer ring with matching sizes can be pushed onto the same third conveyor belt, and the inner ring and outer ring output through this third conveyor belt can be subjected to subsequent assembly operations, realizing the automatic matching of the inner and outer rings of the bearing and greatly improving the production efficiency.

[0008] Optionally, an installation frame is provided on one side of the detection table close to the first conveyor belt. The first transfer assembly includes a translation seat, a translation block, a lifting block, a first transfer member, a second transfer member and a first clamping member. The translation seat is arranged on the installation frame, the translation block is slidably installed on the translation seat, and the lifting block is slidably installed on the translation block. The first transfer member is arranged on the translation seat to drive the translation block to approach or move away from the detection table, and the second transfer member is arranged on the translation block to drive the lifting block to lift and lower. The first clamping member is arranged on the lifting block to clamp the target object.

[0009] By adopting the above technical solution, the second transfer member is used to drive the lifting block to descend, so that the first clamping member clamps the target object on the first conveyor belt, and then the lifting block is driven to lift, so that the target object is lifted off the first conveyor belt. Then, the first transfer member forces the translation block to displace towards one side of the detection table, and then the lifting block is lowered, and the target object can be placed on the detection table, improving the transfer convenience of the target object.

[0010] Optionally, a detection station is provided on the detection table, and the detection device is located directly above the detection station; the second transfer assembly includes a sliding seat, a third transfer member, a fourth transfer member, and a second clamping member. The sliding seat is slidably mounted on the detection table, and a sliding block is slidably mounted on the sliding seat; the third transfer member is disposed on the detection table to drive the sliding seat to approach or move away from the detection station, and the fourth transfer member is disposed on the sliding seat to drive the sliding block to approach or move away from the second conveyor belt; the second clamping member is disposed on the sliding block to clamp the target object.

[0011] By adopting the above technical solution, after the size of the target object is detected, the third transfer member drives the sliding seat to slide towards the detection station, so that the second clamping member can clamp the detected target object; after the second clamping member clamps the target, the fourth transfer member then forces the sliding block to displace towards the side close to the second conveyor belt, thereby transferring the target object to the second conveyor belt, improving the transfer convenience of the target object.

[0012] Optionally, a first slide rail is provided on the sliding seat, and the sliding block is slidably mounted on the first slide rail; the second clamping member includes a first clamping strip, a second clamping strip, a first cylinder, and a second cylinder. One end of the first clamping strip and one end of the second clamping strip are both slidably mounted on the first slide rail, and a first clamping area for clamping the target object is formed between the free ends of the first clamping strip and the second clamping strip; the first cylinder is disposed between the sliding block and the first clamping strip, and the second cylinder is disposed between the sliding block and the second clamping strip. When the piston rods of the first cylinder and the second cylinder both extend, the first clamping strip and the second clamping strip approach each other to jointly clamp the target object.

[0013] By adopting the above technical solution, when transferring the detected target object to the second conveyor belt, the sliding seat is driven to slide towards the detection station, so that the free ends of the first clamping strip and the second clamping strip respectively extend to both sides of the target object (i.e., the target object moves into the first clamping area), and then the piston rods of the first cylinder and the second cylinder are driven to extend outwards, so that the free ends of the first clamping strip and the second clamping strip approach each other to clamp the target object.

[0014] Optionally, a workpiece inspection station is provided on the inspection table, and the workpiece inspection station is located on one side of the inspection station close to the first conveyor belt. The first transfer assembly is used to transfer the target object to the workpiece inspection station on the inspection table. A first sliding bar and a second sliding bar are respectively and slidably mounted on the sliding block. One end of the first clamping bar is connected to the first sliding bar, and one end of the second clamping bar is connected to the second sliding bar. The first sliding bar is connected to a third clamping bar, and the second sliding bar is connected to a fourth clamping bar. The free ends of the third clamping bar and the fourth clamping bar form a second clamping area, and the second clamping area of the third clamping bar and the fourth clamping bar is used to clamp the target object in the workpiece inspection station.

[0015] By adopting the above technical solution, the sliding seat is driven to slide towards the side close to the inspection station, so that the free ends of the first clamping bar and the second clamping bar can respectively extend to both sides of the target object in the inspection station, and the free ends of the third clamping bar and the fourth clamping bar can respectively extend to both sides of the target object in the workpiece inspection station. Then, the piston rods of the first cylinder and the second cylinder are driven to extend outwards, so that the first clamping bar and the second clamping bar can approach each other, and the third clamping bar and the fourth clamping bar can approach each other, thereby clamping the target object in the inspection station and the target object in the workpiece inspection station simultaneously. Then, the sliding block is driven to slide towards the second conveyor belt, so as to transfer the target object that has been inspected in the inspection station to the second conveyor belt, and transfer the target object to be inspected in the workpiece inspection station to the inspection station for inspection, greatly improving the operation convenience and inspection efficiency of the overall structure.

[0016] Optionally, a plurality of sliding grooves are formed on the surface of the inspection table, and the plurality of sliding grooves are arranged at intervals around the center of the workpiece inspection station. A positioning post is slidably mounted in each sliding groove, and the inspection table is provided with a driving assembly for driving the plurality of positioning posts to slide towards or away from the center of the workpiece inspection station simultaneously.

[0017] By adopting the above technical solution, after the target object on the first conveyor belt is transferred to the workpiece inspection station, the driving assembly is used to drive the plurality of positioning posts to slide towards the center of the workpiece inspection station simultaneously. When the plurality of positioning posts are "closed", the target object can be positioned, so that the target object is accurately placed at the center position of the workpiece inspection station, which is not only convenient for the subsequent precise clamping of the third clamping bar and the fourth clamping bar, but also convenient for the subsequent accurate docking of the target object with the inspection equipment, improving the inspection effect.

[0018] Optionally, the driving assembly includes a driving disk and a driving member. The driving disk is rotatably connected to the lower side of the inspection table, and the rotation axis of the driving disk is located at the center position of the to-be-inspected station. A guiding arc groove is formed on the surface of the driving disk. The guiding arc groove has a first point and a second point, and the distance from the first point to the center of the driving disk is greater than the distance from the second point to the center of the driving disk. A plurality of guiding arc grooves are provided and are correspondingly arranged with a plurality of sliding grooves. The lower end of the positioning post of each sliding groove extends into the corresponding guiding arc groove. When the positioning post moves from the first point to the second point, the positioning post gradually slides towards the center of the to-be-inspected station. When the positioning post moves from the second point to the first point, the positioning post gradually slides away from the center of the to-be-inspected station. The driving member is arranged on the inspection table to drive the driving disk to rotate.

[0019] By adopting the above technical solution, after the target object is transferred to the to-be-inspected station, the driving member drives the driving disk to rotate. Under the action of a plurality of guiding arc grooves, the driving disk can drive a plurality of positioning posts to slide synchronously. When the driving disk rotates, it can force the positioning post to move from the first point to the second point, so that the positioning post gradually slides towards the center of the to-be-inspected station, thereby making a plurality of positioning posts "collapse", so as to play a "centering" effect on the target object in the to-be-inspected station, and then facilitating the subsequent accurate docking of the target object with the detection equipment.

[0020] Optionally, a driving rack is slidably installed under the inspection table, and a driving gear ring is coaxially arranged on the outer peripheral wall of the driving disk. The driving rack and the driving gear ring are meshed and driven. The driving member includes a driving block, a connecting rod and a pushing block. The driving block is slidably installed under the inspection table, and the sliding direction of the driving block is the same as the sliding direction of the sliding seat. One end of the connecting rod is hinged to the driving block, and the other end is hinged to the driving rack. The pushing block is arranged at the bottom of the sliding seat. When the sliding seat slides towards the to-be-inspected station, the pushing block forces the driving block to slide.

[0021] By adopting the above technical solution, when the sliding seat slides towards the inspection station, at this time, the sliding seat pushes the driving block through the pushing block, so as to drive the driving rack to slide under the action of the connecting rod, make the driving rack and the driving gear ring meshed and driven, and then drive the driving disk to rotate, so that the driving disk can force a plurality of positioning posts to "collapse".

[0022] Optionally, a second slide rail is provided at the bottom of the inspection table. The two ends of the second slide rail extend along the sliding direction of the sliding seat. The driving block is slidably mounted on the second slide rail, and the driving block is slidably mounted on the inspection table through the second slide rail. The second slide rail has a third position, a fourth position, and a fifth position. The fourth position is located between the third position and the fifth position, and the third position is located on the side of the fourth position close to the sliding seat. When the driving block moves from the third position to the fourth position or from the fifth position to the fourth position, the positioning posts slide towards the center of the workpiece inspection station. When the driving block moves from the fourth position to the third position or from the fourth position to the fifth position, the positioning posts slide away from the center of the workpiece inspection station.

[0023] By adopting the above technical solution, under normal conditions (when the sliding seat is not close to the inspection station), the driving block is located at the third position of the second slide rail at this time, that is, the plurality of positioning posts are in an "open" state, so as to facilitate the transfer of the target object on the first conveyor belt to the workpiece inspection station. After the target object on the first conveyor belt is transferred to the workpiece inspection station, the sliding seat is driven to slide towards the inspection station, forcing the driving block to slide. When the driving block slides to the fourth position, the plurality of positioning posts are in a "closed" state at this time to "center" the target object in the workpiece inspection station. As the sliding seat continues to approach the inspection station, the driving block can be forced to slide to the fifth position, so that the plurality of positioning posts return to the "open" state again, so that the third clamping strip and the fourth clamping strip can clamp the target object that has been "centered" in the workpiece inspection station and transfer it to the inspection station for dimensional inspection, greatly improving the operation convenience of the overall structure.

[0024] Optionally, there are gaps between the bottom wall of the third clamping strip and the surface of the inspection table, and between the bottom wall of the fourth clamping strip and the surface of the inspection table. The height of the bottom wall of the third clamping strip and the height of the bottom wall of the fourth clamping strip are both higher than the upper end surface of the positioning posts.

[0025] By adopting the above technical solution, the height of the bottom wall of the third clamping strip and the height of the bottom wall of the fourth clamping strip are both higher than the upper end surface of the positioning posts, reducing the possibility of interference between the third clamping strip and the fourth clamping strip and the positioning posts when the third clamping strip and the fourth clamping strip transfer the target object in the workpiece inspection station towards the inspection station, and ensuring the normal operation of the overall structure.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. With the settings of the first transfer component, the second transfer component, and the third transfer component, when detecting the size of the target object (inner ring or outer ring), the target object is conveyed to one side of the detection table through the first conveyor belt, and then the target object on the first conveyor belt is transferred to the detection table through the first transfer component. The size of the target object can be detected by the detection device. After the detection is completed, the detected target object is transferred to the second conveyor belt through the second transfer component. According to the detection result, the target object is pushed to the designated third conveyor belt through the third transfer component, greatly improving the detection efficiency of the overall structure. The setting of multiple third conveyor belts enables the classification and output of target objects of different sizes. In practical applications, the inner ring and outer ring with matching sizes can be pushed to the same third conveyor belt, and the inner ring and outer ring output through this third conveyor belt can be used for subsequent assembly operations, realizing the automatic matching of the inner and outer rings of the bearing and greatly improving the production efficiency; 2. With the settings of the third clamping strip and the fourth clamping strip, the sliding seat is driven to slide towards the side close to the detection station, so that the free ends of the first clamping strip and the second clamping strip can respectively extend to both sides of the target object in the detection station, and the free ends of the third clamping strip and the fourth clamping strip can respectively extend to both sides of the target object in the station to be detected. Then, the piston rods of the first cylinder and the second cylinder are driven to extend outwards, enabling the first clamping strip and the second clamping strip to approach each other, and the third clamping strip and the fourth clamping strip to approach each other, so as to clamp the target object in the detection station and the target object in the station to be detected simultaneously. Then, the sliding block is driven to slide towards the second conveyor belt, so as to transfer the detected target object in the detection station to the second conveyor belt and transfer the target object to be detected in the station to be detected to the detection station for detection, greatly improving the operation convenience and detection efficiency of the overall structure; 3. With the settings of the third point, the fourth point, and the fifth point, under normal conditions (when the sliding seat is not close to the detection station), the driving block is located at the third point of the second slide rail at this time, that is, multiple positioning columns are in the "open" state, so as to facilitate the transfer of the target object on the first conveyor belt to the station to be detected. After the target object on the first conveyor belt is transferred to the station to be detected, the sliding seat is driven to slide towards the detection station, forcing the driving block to slide. When the driving block slides to the fourth point, multiple positioning columns are in the "closed" state at this time to "center" the target object in the station to be detected. As the sliding seat continues to approach the detection station, the driving block can be forced to slide to the fifth point, so that multiple positioning columns return to the "open" state again, so as to facilitate the third clamping strip and the fourth clamping strip to clamp the target object that has been "centered" in the station to be detected and transfer it to the detection station for size detection, greatly improving the operation convenience of the overall structure.

[0043] It should be noted that in this embodiment, clamping blocks 632 are connected to the free ends of the first clamping strip 63, the second clamping strip 64, the free end of the third clamping strip 67, and the free end of the fourth clamping strip 68. The clamping blocks 632 can be installed in the form of bolt connection, and the clamping blocks 632 have clamping arc surfaces 633 for abutting against the outer peripheral wall of the target object 9.

[0044] Refer to Figure 1 , the third conveyor belt 4 is installed on the side of the second conveyor belt 3 away from the first conveyor belt 2. A plurality of third conveyor belts 4 are arranged at intervals along the length direction of the second conveyor belt 3, and the inlet end of each third conveyor belt 4 is connected to the second conveyor belt 3; a third transfer assembly 7 is provided on the second conveyor belt 3. The number of the third transfer assemblies 7 is correspondingly set with the number of the third conveyor belts 4. The third transfer assembly 7 is used for pushing the target object 9 on the second conveyor belt 3 onto the third conveyor belt 4.

[0045] In this embodiment, an installation strip 31 is fixedly installed on the side wall of the second conveyor belt 3. The third transfer assembly 7 includes a push plate 71 and a fifth cylinder 72. The cylinder body of the fifth cylinder 72 is fixedly installed on the installation strip 31. The piston rod of the fifth cylinder 72 passes through the installation strip 31 and is fixedly connected to the push plate 71. The push plate 71 is slidably installed on the second conveyor belt 3 through the fifth cylinder 72. When the piston rod of the fifth cylinder 72 extends outwards, the push plate 71 pushes the target object 9 on the second conveyor belt 3 onto the corresponding third conveyor belt 4.

[0046] The implementation principle of Embodiment 1 of this application is as follows: When performing dimensional inspection on the target object 9, the target object 9 to be inspected on the first conveyor belt 2 is transferred to the inspection station 141 on the inspection plate 14 by the jaw cylinder 55; then, the sliding seat 61 is driven to slide toward the side close to the inspection station 131, so that the free ends of the third clamping strip 67 and the fourth clamping strip 68 extend to both sides of the target object 9 in the inspection station 141; then, through the cooperation of the first cylinder 65 and the second cylinder 66, the free ends of the third clamping strip 67 and the fourth clamping strip 68 can clamp the target object 9 on the inspection station 141; then, the sliding block 62 is driven to slide toward the side of the second conveyor belt 3, and the target object 9 in the inspection station 141 can be transferred to the inspection station 131. At the same time, the first clamping strip 63 and the second clamping strip 64 can transfer the target object 9 that has been inspected in the inspection station 131 to the second conveyor belt 3. By driving the lifting plate 132 to lift, the target object 9 in the inspection station 131 can be lifted to the inspection device 11 for dimensional inspection (during this process, the sliding seat 61 and the sliding block 62 are reset, that is, the sliding seat 61 slides back to the side away from the inspection station 131 again, and the sliding block 62 slides back to the side of the sliding seat 61 away from the second conveyor belt 3). In this way, the dimensional inspection of multiple target objects 9 can be continuously performed, greatly improving the inspection efficiency.

[0047] According to the inspection results, the target object 9 is pushed to the designated third conveyor belt 4 by the push plate 71, greatly improving the inspection efficiency of the overall structure. The setting of multiple third conveyor belts 4 can output target objects 9 of different sizes in a classified manner. In practical applications, the inner ring and the outer ring with matching sizes can be pushed to the same third conveyor belt 4. The inner ring and the outer ring output by this third conveyor belt 4 can then perform subsequent assembly operations, realizing the automatic matching of the inner and outer rings of the bearing, and enabling the assembly error between the assembled inner ring and outer ring to be controlled within a reasonable range, greatly improving the production efficiency.

[0048] Embodiment 2: This application embodiment discloses a hub bearing automatic matching device.

[0049] The difference between the hub bearing automatic matching device disclosed in this application embodiment and Embodiment 1 is that: Refer to Figure 6, in this embodiment, a plurality of sliding grooves 15 are formed on the surface of the to-be-inspected plate 14, and the plurality of sliding grooves 15 are arranged at intervals around the center of the to-be-inspected station 141. A positioning block 19 is disposed in each sliding groove 15, and the positioning block 19 is slidably installed in the sliding groove 15 so as to be able to slide along the length direction of the sliding groove 15; a positioning column 16 is installed on each positioning block 19, and the upper end surface of the positioning column 16 is higher than the upper surface of the to-be-inspected plate 14. It should be noted that there are gaps between the bottom wall of the third clamping strip 67 and the surface of the inspection table 1, and between the bottom wall of the fourth clamping strip 68 and the surface of the inspection table 1. The height of the bottom wall of the third clamping strip 67 and the height of the bottom wall of the fourth clamping strip 68 are both higher than the upper end surface of the positioning column 16.

[0050] Refer to Figure 7 , Figure 8 , the inspection table 1 is provided with a driving assembly 8, and the driving assembly 8 is used to drive a plurality of positioning columns 16 to slide simultaneously towards or away from the center of the to-be-inspected station 141; the driving assembly 8 includes a driving disk 81 and a driving member. The driving disk 81 is coaxially fixed with a rotating shaft 814, and the rotating shaft 814 is rotatably installed on the lower surface of the to-be-inspected plate 14, and the central axis of the rotating shaft 814 is located at the center position of the to-be-inspected station 141; a guiding arc groove 811 is formed on the surface of the driving disk 81, the guiding arc groove 811 is arc-shaped, the guiding arc groove 811 has a first point 812 and a second point 813, and the distance from the first point 812 to the center of the driving disk 81 is greater than the distance from the second point 813 to the center of the driving disk 81; a plurality of guiding arc grooves 811 are provided and are correspondingly arranged with the plurality of sliding grooves 15. The lower ends of the positioning columns 16 in each sliding groove 15 extend into the corresponding guiding arc groove 811. When the positioning column 16 transfers from the first point 812 to the second point 813, the positioning column 16 gradually slides towards the center of the to-be-inspected station 141. When the positioning column 16 transfers from the second point 813 to the first point 812, the positioning column 16 gradually slides away from the center of the to-be-inspected station 141.

[0051] Refer to Figure 7 , the driving member is disposed on the inspection table 1 to drive the driving disk 81 to rotate. A driving rack 82 is slidably installed on the lower surface of the to-be-inspected plate 14, and both ends of the driving rack 82 extend along the length direction of the sliding seat 61. A driving gear ring 83 is coaxially fixed on the outer peripheral wall of the driving disk 81, and the driving rack 82 and the driving gear ring 83 are meshed and driven; the driving member includes a driving block 84, a connecting rod 85 and a pushing block 86. A second sliding rail 17 is fixedly installed on the lower surface of the to-be-inspected plate 14, and both ends of the second sliding rail 17 extend along the sliding direction of the sliding seat 61. The driving block 84 is slidably installed on the second sliding rail 17, and the driving block 84 is slidably installed under the to-be-inspected plate 14 of the inspection table 1 through the second sliding rail 17.

[0052] One end of the connecting rod 85 is hinged to the driving block 84, and the other end is hinged to the driving rack 82; the pushing block 86 is fixedly installed at the bottom of the sliding seat 61 (the sliding seat 61 is not shown in this embodiment). When the sliding seat 61 slides towards the inspection station 141, the pushing block 86 forces the driving block 84 to slide. It should be noted that in this embodiment, a return torsion spring (not shown in the figure) is provided between the rotating shaft 814 and the inspection plate 14, and the return torsion spring forces the driving block 84 and the pushing block 86 to always be in contact with each other. In other embodiments, the pushing block 86 and the driving block 84 can be fixedly connected.

[0053] Referring to Figure 7 , the second slide rail 17 has a third position 171, a fourth position 172, and a fifth position 173. The fourth position 172 is located between the third position 171 and the fifth position 173, and the third position 171 is located on the side of the fourth position 172 close to the sliding seat 61; when the driving block 84 moves from the third position 171 to the fourth position 172 or from the fifth position 173 to the fourth position 172, the positioning post 16 slides towards the center of the inspection station 141; when the driving block 84 moves from the fourth position 172 to the third position 171 or from the fourth position 172 to the fifth position 173, the positioning post 16 slides away from the center of the inspection station 141.

[0054] Under normal conditions (when the sliding seat 61 is not close to the inspection station 141), the driving block 84 is displaced to the third position 171 under the action of the return torsion spring; when the sliding seat 61 moves towards the inspection station 141 so that the free ends of the third clamping strip 67 and the fourth clamping strip 68 extend to both sides of the target object 9 in the inspection station 141 respectively, the driving block 84 is displaced to the fifth position 173.

[0055] Referring to Figure 6 、 Figure 9 , in this embodiment, the positioning post 16 includes a positioning portion 161, a connecting portion 162, and a rotating portion 163. The positioning portion 161 is fixedly installed on the upper end surface of the connecting portion 162. The outer diameter of the positioning portion 161 is larger than the outer diameter of the connecting portion 162. The positioning portion 161 is exposed on the upper surface of the inspection plate 14 for positioning the target object 9, and an elastically arranged cushion 164 is fixedly installed on the outer peripheral wall of the positioning portion 161.

[0056] The positioning blocks 19 are respectively provided with a first connection hole 191 and a second connection hole 192. The connecting portion 162 is used for threadedly passing through the first connection hole 191 or the second connection hole 192 (the thread of the connecting portion 162 is not shown in the figure). It should be noted that when the target object 9 is the inner ring, the connecting portion 162 is threadedly connected to the first connection hole 191, and when the target object 9 is the outer ring, the connecting portion 162 is threadedly connected to the second connection hole 192. The rotating portion 163 is rotatably mounted on the lower end surface of the connecting portion 162. The outer diameter of the rotating portion 163 is smaller than the outer diameter of the connecting portion 162. The rotating portion 163 is used for extending into the guiding arc groove 811 of the driving disc 81.

[0057] The implementation principle of Embodiment 2 of this application is as follows: After the target object 9 on the first conveyor belt 2 is transferred to the inspection station 141, the sliding seat 61 is driven to slide toward the side close to the inspection station 131. The sliding seat 61 pushes the driving block 84, thereby forcing the driving disc 81 to rotate. Under the action of the guiding arc groove 811, when the plurality of positioning posts 16 are "closed", the target object 9 can be positioned, so that the target object 9 is accurately placed at the central position of the inspection station 141, which is convenient for the subsequent precise clamping of the third clamping strip 67 and the fourth clamping strip 68, and is also convenient for the subsequent target object 9 to accurately dock with the inspection device 11, improving the inspection effect.

[0058] Under normal conditions (when the sliding seat 61 is not close to the inspection station 141), at this time, the driving block 84 is located at the third point 171 of the second slide rail 17, that is, the plurality of positioning posts 16 are in an "open" state, so as to facilitate the transfer of the target object 9 on the first conveyor belt 2 to the inspection station 141. After the target object 9 on the first conveyor belt 2 is transferred to the inspection station 141, the sliding seat 61 is driven to slide toward the inspection station 131, forcing the driving block 84 to slide. When the driving block 84 slides to the fourth point 172, at this time, the plurality of positioning posts 16 are in a "closed" state to "center" the target object 9 in the inspection station 141. As the sliding seat 61 continues to approach the inspection station 131, the driving block 84 can be forced to slide to the fifth point 173, so that the plurality of positioning posts 16 return to the "open" state again, so that the third clamping strip 67 and the fourth clamping strip 68 can clamp the target object 9 that has been "centered" in the inspection station 141 and transfer it to the inspection station 131 for dimensional inspection, greatly improving the operation convenience of the overall structure.

[0059] The above is the preferred embodiment of this application. It does not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
