Description

Technical Field

[0001] The present invention relates to the technical field of concentricity detection of the inner hole of a pin sleeve, and specifically to a concentricity detection device for the inner hole of a pin sleeve. Background Art

[0002] A pin sleeve is a hard steel sleeve that strengthens the positioning pin hole. There are several types of pin sleeves. There is a positioning pin sleeve, which is a hard steel sleeve that strengthens the positioning pin hole, and there is also a stud pin sleeve. In a cycloid pinwheel planetary transmission mechanism, it is sleeved on the stud pin in the output mechanism of the pin hole and meshes with the cylindrical surface of the corresponding stud pin hole on the cycloid wheel, and is widely used. During the processing of the pin sleeve, it is necessary to detect the concentricity of its inner hole. By detecting the concentricity, it is beneficial to know the quality of the current pin sleeve. A concentricity detection device is required for concentricity detection.

[0003] For example, the utility model with the application number CN202321726882.0 relates to the technical field of pin sleeve processing equipment, and discloses a concentricity detection device for the inner hole of a pin sleeve, including a self-centering three-jaw chuck mechanism. By setting the self-centering three-jaw chuck mechanism, the first movable jaw mechanism, the second movable jaw mechanism, and the third movable jaw mechanism on the self-centering three-jaw chuck mechanism rotate through the first arc groove, the second arc groove, and the third arc groove on the rotating disk and extend outwards to clamp and fix the inner hole of the pin sleeve self-centered, so that the concentricity of the pin sleeve is consistent with the concentricity of the concentricity detection device when it is fixed, ensuring the accuracy of the detection result of the concentricity detection device and avoiding the occurrence of detection errors in the concentricity detection device. However, when the concentricity of the pin sleeve is detected, manual loading and unloading are required, increasing the manual labor workload and making it inconvenient for users to use.

[0016] The present invention provides a concentricity detection device for the inner hole of a pin sleeve, having the following beneficial effects:

[0017] 1. In this concentricity detection device for the inner hole of a pin sleeve, through the design of the driving motor and the conveyor belt, the drive shaft can be driven to rotate. Through the rotation of the drive shaft, the side disc and the transmission rod connected thereto can follow the movement. At the same time, the connecting rod and the vertical plate will rotate synchronously, so that the connecting shaft and the connecting shaft connected to the vertical plate will follow the movement. The fixed frame on the outer surface of the connecting shaft will rotate, so that the entire fixed frame will adjust the angle or reset to one side of the material plate.

[0018] 2. In this concentricity detection device for the inner hole of a pin sleeve, after limiting, by adjusting the angle of the positioning frame, the pin sleeve after limiting can be made to be in the same position as the detection position of the concentricity detector, which is beneficial to using the concentricity detector to detect the concentricity of the pin sleeve. While improving the detection efficiency, after the detection is completed, through the re-adjustment of the angle of the positioning frame, the pin sleeve after concentricity detection can be automatically collected, without manual participation, which is convenient for large-scale concentricity detection of the pin sleeve.

[0019] 3. In this concentricity detection device for the inner hole of a pin sleeve, through the design of the positioning component, when the lead screw rotates, the threaded sleeve plate and the positioning plate can approach or move away from each other. Thus, when the positioning plate extends into the inner hole of the pin sleeve, it can support and fix. Through the design of the pushing component, it is beneficial to use two groups of positioning plates to support and fix the inner hole of the pin sleeve. In addition, after the concentricity detection of the pin sleeve is completed, the pin sleeve can be placed at the initial position in the material groove, which is convenient for the electric push rod to drive the position movement of the rubber push plate again, and is beneficial to pushing the pin sleeve after concentricity detection into the guiding frame, which is convenient for the unified collection of the pin sleeve after detection.

The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0028] As Figure 1 、 Figure 2 and Figure 3As shown in the figure, the present invention provides a technical solution: a concentricity detection device for the inner hole of a pin sleeve, including a vertical plate 1, a driving motor 2, a conveyor belt 3, a transmission shaft 4, a concentricity detector 5, a support assembly 6, an upper support frame 601, a lower support plate 602, a fixed table 603, a cleaning brush plate 7, a transmission assembly 8, a side plate 801, a transmission rod 802, a connecting rod 803, a vertical plate 804, a driving assembly 9, a connecting shaft 901, a connecting shaft 902, a first gear 903, a fixing plate 10, a support column 11, an adjusting assembly 12, a fixing frame 1201, a second gear 1202, a bushing 1203, an inner shaft 1204, a positioning frame 13, a positioning assembly 14, a servo motor 1401, a lead screw 1402, a threaded sleeve plate 1403, a positioning plate 1404, a pushing assembly 15, a fixed side plate 1501, an electric push rod 1502, a rubber push plate 1503, a material trough 16, a threaded plate 17, a threaded rod 18, an inner plate 19, an inner side groove 20, a guiding frame 21 and a material plate 22. A driving motor 2 is arranged on the outer side of one side of the vertical plate 1, and a transmission shaft 4 is installed outside the driving motor 2 through a conveyor belt 3. A cleaning brush plate 7 is clamped and installed on the outer surface of one side of the top of the vertical plate 1. A positioning frame 13 is arranged outside the cleaning brush plate 7. By rotating the fixing frame 1201, the positioning frame 13 can be driven to move synchronously, so that the ventilation area on one side of the servo motor 1401 can be cleaned by the cleaning brush plate 7 during the movement, which is convenient for the servo motor 1401 to maintain a good ventilation effect. One end of the transmission shaft 4 is provided with a transmission assembly 8 for auxiliary driving, and the transmission assembly 8 includes a side plate 801, a transmission rod 802, a connecting rod 803 and a vertical plate 804. A transmission rod 802 is arranged on the outer surface of the side plate 801, and a connecting rod 803 is rotatably installed at the end of the transmission rod 802. A vertical plate 804 is rotatably arranged at the end of the connecting rod 803. A driving assembly 9 for following rotation is installed on one side of the bottom of the vertical plate 804, and the driving assembly 9 includes a connecting shaft 901, a connecting shaft 902 and a first gear 903. A fixing plate 10 is arranged outside one side of the first gear 903, and support columns 11 are installed on both sides of the bottom of the fixing plate 10. One end of the connecting shaft 901 is provided with a connecting shaft 902, and a first gear 903 is arranged outside one side of the connecting shaft 902. An adjusting assembly 12 for secondary angle adjustment is installed outside the first gear 903, and the adjusting assembly 12 includes a fixing frame 1201, a second gear 1202, a bushing 1203 and an inner shaft 1204. A second gear 1202 is meshed and installed on the outer surface of the first gear 903, and an inner shaft 1204 is arranged in the middle of the second gear 1202. A bushing 1203 is installed outside the inner shaft 1204, and a positioning frame 13 is arranged at the top of the inner shaft 1204. The material plate 22 is arranged on the side of the vertical plate 1 away from the driving motor 2, and a concentricity detector 5 is installed above one side of the outer side of the vertical plate 1. By the design of the driving motor 2 and the conveyor belt 3, the transmission shaft 4 can be driven to rotate. By the rotation of the transmission shaft 4, the side plate 801 and the transmission rod 802 connected thereto can be driven to move synchronously.Meanwhile, the connecting rod 803 and the vertical plate 804 will rotate synchronously, so that the connecting shaft 901 and the connecting shaft 902 connected to the vertical plate 804 will follow the movement. The fixed frame 1201 on the outer surface of the connecting shaft 902 will rotate accordingly, so that the entire fixed frame 1201 will adjust the angle or reset to one side of the material plate 22. During the process of the fixed frame 1201 adjusting the angle to one side, the first gear 903 and the second gear 1202 mesh with each other, so that the second gear 1202 will rotate. The built-in shaft 1204 and the positioning frame 13 connected to the second gear 1202 will follow the movement, which is beneficial to using the design of the positioning component 14 inside the positioning frame 13 to limit the inner hole of the pin sleeve in the material plate 22. After the limitation, through the above-mentioned angle adjustment, the position of the pin sleeve after the limitation is kept consistent with the detection position of the concentricity detector 5, which is beneficial to using the concentricity detector 5 to detect the concentricity of the pin sleeve. While improving the detection efficiency, after the detection is completed, the pin sleeve after the concentricity detection can be automatically collected by adjusting the angle of the positioning frame 13 again, without manual participation, which is convenient for batch concentricity detection of the pin sleeve.

[0029] As Figure 1 、 Figure 3 and Figure 4 shown, a support component 6 for height adjustment is installed at the bottom of the concentricity detector 5, and the support component 6 includes an upper support frame 601, a lower support plate 602 and a fixed table 603. The lower support plate 602 is slidably installed inside the upper support frame 601, and a fixed table 603 is arranged at the bottom of the lower support plate 602. The fixed table 603 is in an "L" shape, and one side outer surface of the fixed table 603 is integrally structured with the vertical plate 1. Through the sliding design between the upper support frame 601 and the lower support plate 602, it is convenient to adjust the horizontal height of the concentricity detector 5 with respect to the positioning frame 13. After the height adjustment is completed, the upper support frame 601 and the lower support plate 602 are fixed by using the design of bolts, which is convenient to adapt the detection position of the concentricity detector 5 according to the size of the pin sleeve. A positioning component 14 for clamping the inner hole of the pin sleeve is installed inside the positioning frame 13, and the positioning component 14 includes a servo motor 1401, a lead screw 1402, a threaded sleeve plate 1403 and a positioning plate 1404. The output end of the positioning component 14 is installed with a lead screw 1402 through a shaft, and a threaded sleeve plate 1403 is threadedly arranged on the outer surface of the lead screw 1402. A positioning plate 1404 is installed in the middle of one side of the outer surface of the threaded sleeve plate 1403. Through the design of the servo motor 1401 and the shaft, the lead screw 1402 can be driven to rotate. The thread directions of the two ends of the lead screw 1402 are opposite, so that when the lead screw 1402 rotates, the threaded sleeve plate 1403 and the positioning plate 1404 can approach or move away from each other, so that when the positioning plate 1404 extends into the inner hole of the pin sleeve, it can be supported and fixed.

[0030] As Figure 1 、 Figure 5and Figure 6 As shown in Figure 6 , a material groove 16 is provided in the middle of the material plate 22. A guiding frame 21 is provided at one end of the material groove 16 away from the pushing assembly 15. The guiding frame 21 is arranged on one side of the outer surface of the vertical plate 1. A pushing assembly 15 for assisting in loading and unloading is installed at one end of the material groove 16. The pushing assembly 15 includes a fixed side plate 1501, an electric push rod 1502 and a rubber push plate 1503. The electric push rod 1502 is arranged on the outer surface of the fixed side plate 1501, and the rubber push plate 1503 is installed at the output end of the electric push rod 1502. Through the design that the material groove 16 is recessed in the material plate 22, it is convenient to place the bushing in the material groove 16. After the placement is completed, the position of the rubber push plate 1503 can be moved through the design of the fixed side plate 1501 and the electric push rod 1502. Through the position movement of the rubber push plate 1503, the bushing placed in the material groove 16 can be pushed outside the two positioning plates 1404, which is beneficial to use the two positioning plates 1404 to support and fix the inner hole of the bushing. In addition, after the concentricity detection of the bushing is completed, the bushing can be placed at the initial position in the material groove 16, which is convenient to use the electric push rod 1502 to drive the rubber push plate 1503 to move again, which is beneficial to push the bushing after the concentricity detection into the guiding frame 21, which is convenient to uniformly collect the bushing after the detection. Built-in side grooves 20 are provided on both sides inside the material plate 22, and an inner plate 19 is slidably installed inside the built-in side grooves 20. A threaded rod 18 is rotatably installed on one side of the inner plate 19, and a threaded plate 17 is provided at the end of the threaded rod 18 in a threaded manner, and the threaded plate 17 is fixedly arranged on both sides of the outer surface of the material plate 22. A bushing is placed inside the material groove 16. By rotating the threaded rod 18, the inner plate 19 at the end of the threaded rod 18 can be controlled to move with respect to the material groove 16, which is convenient to align the bushings placed in the material groove 16, and is convenient to quickly support and fix the inner hole of the bushing by using the positioning plates 1404 subsequently.

[0031] In summary, as Figures 1-6As shown, for the concentricity detection device of the inner hole of the pin sleeve, during use, due to the design that the material groove 16 is recessed in the material plate 22, it is convenient to place the pin sleeve inside the material groove 16. After the placement is completed, through the design of the fixed side plate 1501 and the electric push rod 1502, the position of the rubber push plate 1503 can be moved. Through the position movement of the rubber push plate 1503, the pin sleeve placed inside the material groove 16 can be pushed to the outside of the two positioning plates 1404, which is beneficial to using the two positioning plates 1404 to support and fix the inner hole of the pin sleeve. In addition, after the concentricity detection of the pin sleeve is completed, the pin sleeve can be placed at the initial position in the material groove 16, which is convenient to use the electric push rod 1502 again to drive the position movement of the rubber push plate 1503, and is beneficial to pushing the pin sleeve after the concentricity detection into the guiding frame 21, which is convenient to uniformly collect the pin sleeve after the detection. When the pin sleeve is placed inside the material groove 16, by rotating the threaded rod 18, the built-in plate 19 at the end of the threaded rod 18 can be controlled to move with respect to the material groove 16, which is convenient to align the pin sleeves placed in the material groove 16, and is convenient to quickly support and fix the inner hole of the pin sleeve by using the positioning plates 1404 subsequently. During the feeding and detection, through the design of the driving motor 2 and the conveyor belt 3, the transmission shaft 4 can be driven to rotate. Through the rotation of the transmission shaft 4, the side plate 801 and the transmission rod 802 connected to it can follow. At the same time, the connecting rod 803 and the vertical plate 804 will rotate synchronously, so that the connecting shaft 901 and the connecting shaft 902 connected to the vertical plate 804 will follow. The fixed frame 1201 on the outer surface of the connecting shaft 902 will rotate, so that the entire fixed frame 1201 will adjust the angle or reset to one side of the material plate 22. During the process of the fixed frame 1201 adjusting the angle to one side, the first gear 903 and the second gear 1202 are meshed with each other, so that the second gear 1202 will rotate, and the built-in shaft 1204 and the positioning frame 13 connected to the second gear 1202 will follow. It is beneficial to use the design of the positioning component 14 inside the positioning frame 13 to limit the inner hole of the pin sleeve in the material plate 22. After the limiting, through the above-mentioned angle adjustment, the pin sleeve after the limiting can be kept in the same detection position as the concentricity detector 5, which is beneficial to using the concentricity detector 5 to detect the concentricity of the pin sleeve. While improving the detection efficiency, after the detection is completed, through the re-angle adjustment of the positioning frame 13, the pin sleeve after the concentricity detection can be automatically collected. When the positioning frame 13 fixes the pin sleeve, through the design of the servo motor 1401 and the shaft, the lead screw 1402 can be driven to rotate. The thread directions on the outer surfaces of both ends of the lead screw 1402 are opposite, so that when the lead screw 1402 rotates, the threaded sleeve plate 1403 and the positioning plate 1404 can approach or move away from each other. Thus, when the positioning plate 1404 extends into the inner hole of the pin sleeve, it can be supported and fixed. Finally, through the sliding design between the upper support frame 601 and the lower support plate 602, it is convenient to adjust the horizontal height of the concentricity detector 5 with respect to the positioning frame 13. After the height adjustment is completed, the upper support frame 601 and the lower support plate 602 are fixed by using the design of bolts.It is convenient to adapt the detection position of the concentricity detector 5 according to the size of the pin bushing.
