Description

Technical Field

[0001] This utility model relates to the field of bending degree detection devices, specifically a bending degree detection device for elbows. Background Technology

[0002] Elbow curvature testing devices are specialized equipment or systems used to accurately measure the geometric parameters of pipe elbows. Their core purpose is to ensure that the actual bending angle, radius, roundness and other key dimensions of the elbows meet the requirements of the design drawings or relevant standards, thereby ensuring their installation accuracy, fluid transport efficiency and structural safety in the pipeline system.

[0003] In existing technologies, after the elbows are manufactured, the curvature of the elbows is generally detected manually using measuring tools. However, traditional elbow curvature detection requires repeatedly loading the measuring tools with elbows to be measured for the entire batch of elbows, resulting in low detection efficiency and low detection accuracy. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, traditional elbow curvature testing requires repeatedly loading the elbows to be measured onto the measuring tool to test the curvature of the entire batch of elbows, resulting in low testing efficiency and low testing accuracy. This utility model proposes an elbow curvature testing device.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a bend curvature detection device, including a base, a bracket fixedly connected to one side of the base, a visual inspection instrument provided on one side of the bracket, and a filling mechanism provided in the inner cavity of the base.

[0006] The loading mechanism includes a rotating disk rotatably connected to the inner cavity of the base. A support block is fixedly connected to one side of the rotating disk, and there are multiple support blocks. A first rotating shaft is fixedly connected to one side of the rotating disk. The surface of the first rotating shaft is rotatably connected to the inner cavity of the base. A first disc is fixedly connected to the surface of the first rotating shaft. A sliding groove is formed on one side of the first disc. A motor is fixedly connected to the inner cavity of the base. A second rotating shaft is fixedly connected to the output end of the motor. A second disc is fixedly connected to one end of the second rotating shaft. A limit post is fixedly connected to one side of the second disc. The surface of the limit post is slidably connected to the inner wall of the sliding groove.

[0007] Preferably, the surface of the first rotating shaft is fixedly connected with a first thread, the inner cavity of the base is rotatably connected with a crossbar, the surface of the crossbar is fixedly connected with a first gear, and the surface of the first thread meshes with the teeth of the first gear.

[0008] Preferably, the surface of the crossbar is fixedly connected with a second thread, the inner cavity of the base is rotatably connected with a vertical rod, the surface of the vertical rod is fixedly connected with a second gear, and the surface of the second thread meshes with the teeth of the second gear.

[0009] Preferably, a support plate is fixedly connected to the inner cavity of the base, and a cam is fixedly connected to the surface of the vertical rod, with the surface of the cam rotatably connected to the inner cavity of the support plate.

[0010] Preferably, a slider is slidably connected to the inner cavity of the support disk, one side of the slider is in contact with the surface of the cam, and a telescopic damping rod is fixedly connected to the inner cavity of the support disk. One end of the telescopic damping rod is fixedly connected to one side of the slider, and a first spring is sleeved on the surface of the telescopic damping rod. One end of the first spring is fixedly connected to one side of the slider, and the other end of the first spring is fixedly connected to the inner cavity of the support disk.

[0011] Preferably, the inner cavity of the slider is slidably connected to a limiting block, a limiting groove is formed on one side of the support plate, one side of the limiting block is slidably connected to the inner cavity of the limiting groove, and a second spring is fixedly connected to one side of the limiting block.

[0012] Preferably, the inner cavity of the limiting block is slidably connected to a clamping plate, and a third spring is fixedly connected to one side of the clamping plate, with one end of the third spring fixedly connected to the inner cavity of the limiting block.

[0013] The advantages of this utility model are:

[0014] This invention features a loading mechanism. A motor operates, controlling the rotation of a second rotating shaft fixedly connected to its output end. This second rotating shaft drives a second disc fixedly connected to one end to rotate, along with a limiting post fixedly connected to one side of the second disc. When the limiting post rotates into the groove formed by the first disc, it drives the first disc to rotate within the groove. This continues until the limiting post leaves the groove, at which point the first disc stops rotating. This achieves a situation where, for every one rotation of the second disc, the first disc drives the first rotating shaft fixedly connected to it to rotate a quarter rotation. This, in turn, drives a rotating disc fixedly connected to one end and a support block fixed to the rotating disc. By rotating the second disc twice, the elbow supported by the support block on one side is transported to the other side, achieving autonomous loading. This solves the problems of traditional elbow bending inspection, which requires repeatedly loading elbows to be measured onto measuring tools for bending inspection of an entire batch of elbows, resulting in low inspection efficiency and low accuracy.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0025] This application discloses a device for detecting the curvature of an elbow. (Refer to...) Figures 1 to 6A device for detecting the curvature of an elbow includes a base 1, a bracket 2 fixedly connected to one side of the base 1, a visual inspection instrument 3 provided on one side of the bracket 2, and a filling mechanism 4 provided in the inner cavity of the base 1.

[0026] The filling mechanism 4 includes a rotating disk 401, which is rotatably connected to the inner cavity of the base 1. A support block 402 is fixedly connected to one side of the rotating disk 401. Multiple support blocks 402 are present. A first rotating shaft 403 is fixedly connected to one side of the rotating disk 401. The surface of the first rotating shaft 403 is rotatably connected to the inner cavity of the base 1. A first disc 404 is fixedly connected to the surface of the first rotating shaft 403. A groove 405 is formed on one side of the first disc 404. A motor 406 is fixedly connected to the inner cavity of the base 1. A second rotating shaft 407 is fixedly connected to the output end of the motor 406. A second disc 408 is fixedly connected to one end of the second rotating shaft 407. A limit post 409 is fixedly connected to one side of the second disc 408. The surface of the limit post 409 is slidably connected to the inner wall of the groove 405. By setting up the filling mechanism 4, the motor 406 operates, controlling the rotation of the second rotating shaft 407 fixedly connected to its output end. This causes the second rotating shaft 407 to drive the second disc 408 fixedly connected to its output end. 08 rotates and rotates with the limiting post 409 fixedly connected to one side of the second disk 408. When the limiting post 409 rotates to the groove 405 opened in the first disk 404 and enters the groove 405, the limiting post 409 drives the first disk 404 to rotate within the groove 405 until the limiting post 409 leaves the groove 405, at which point the first disk 404 stops moving. This achieves that for every one revolution of the second disk 408, the first disk 404 drives the first rotating shaft 403 fixedly connected to it to rotate. A quarter turn, thus the first rotating shaft 403 drives the rotating disk 401 fixedly connected to one end and the support block 402 fixed on the rotating disk 401 to rotate twice through the second disk 408, so that the elbow supported by the support block 402 on one side is transported to the other side. The vision inspection instrument 3 is an existing structure, its model is Keyence, and its structure includes an industrial control computer, an industrial camera, a lighting device and a vision processor. The vision inspection instrument 3 can receive and process the elbow image and analyze the curvature of the elbow.

[0027] Reference Figure 3 and Figure 4 The surface of the first rotating shaft 403 is fixedly connected with a first thread 5, and the inner cavity of the base 1 is rotatably connected with a crossbar 6. The surface of the crossbar 6 is fixedly connected with a first gear 7. The surface of the first thread 5 meshes with the teeth of the first gear 7. By setting the first thread 5, since the surface of the first thread 5 meshes with the teeth of the first gear 7, the first thread 5 rotates with the first rotating shaft 403, driving the first gear 7 that meshes with it to rotate, thereby the first gear 7 drives the crossbar 6 that is fixedly connected to it to rotate.

[0028] Reference Figure 4 The surface of the crossbar 6 is fixedly connected with a second thread 8, and the inner cavity of the base 1 is rotatably connected with a vertical rod 9. The surface of the vertical rod 9 is fixedly connected with a second gear 10. The surface of the second thread 8 meshes with the teeth of the second gear 10. By setting the second thread 8, since the surface of the second thread 8 meshes with the teeth of the second gear 10, the second thread 8 rotates with the crossbar 6, driving the meshed second gear 10 to rotate, thereby the second gear 10 drives the fixedly connected vertical rod 9 to rotate.

[0029] Reference Figure 4 and Figure 5 A support plate 11 is fixedly connected to the inner cavity of the base 1, and a cam 12 is fixedly connected to the surface of the vertical rod 9. The surface of the cam 12 is rotatably connected to the inner cavity of the support plate 11. By setting the cam 12, the cam 12 rotates with the vertical rod 9, and its protruding part can periodically push the slider 13.

[0030] Reference Figure 5 A slider 13 is slidably connected to the inner cavity of the support plate 11. One side of the slider 13 is attached to the surface of the cam 12. A telescopic damping rod 14 is fixedly connected to the inner cavity of the support plate 11. One end of the telescopic damping rod 14 is fixedly connected to one side of the slider 13. A first spring 15 is sleeved on the surface of the telescopic damping rod 14. One end of the first spring 15 is fixedly connected to one side of the slider 13, and the other end of the first spring 15 is fixedly connected to the inner cavity of the support plate 11. By setting the slider 13, as the cam 12 rotates to its protruding part, it pushes the slider 13, so that the slider 13 can drive the limiting block 16 on one side to move. While the slider 13 is moving, it will squeeze the first spring 15, so that the first spring 15 accumulates elastic potential energy. When the cam 12 rotates to its non-protruding part and contacts the slider 13, the first spring 15 releases elastic potential energy, so that the slider 13 and the limiting block 16 are reset.

[0031] Reference Figures 4 to 6 The inner cavity of the slider 13 is slidably connected to the limiting block 16. A limiting groove 17 is opened on one side of the support plate 11. One side of the limiting block 16 is slidably connected to the inner cavity of the limiting groove 17. A second spring 18 is fixedly connected to one side of the limiting block 16. By setting the limiting groove 17, the limiting block 16 is pushed along with the slider 13. Since the limiting block 16 is limited by the limiting groove 17 and the limiting groove 17 is trapezoidal, when the limiting block 16 moves, the limiting groove 17 will push the limiting block 16 to gradually close and clamp the limiting blocks 16 on both sides. By setting the second spring 18, the gradual closing and clamping of the limiting blocks 16 on both sides will cause the second spring 18 to contract and accumulate elastic potential energy. When the limiting block 16 is pushed back to its original position by the first spring 15, the second spring 18 will release elastic potential energy after losing the restriction of the limiting groove 17, causing the limiting blocks 16 on both sides to open.

[0032] Reference Figure 6The inner cavity of the limiting block 16 is slidably connected to a clamping plate 19. A third spring 20 is fixedly connected to one side of the clamping plate 19. One end of the third spring 20 is fixedly connected to the inner cavity of the limiting block 16. By setting the clamping plate 19, when the clamping plate 19 is not in contact with the elbow, the clamping plate 19 will move with the limiting block 16 until the clamping plate 19 contacts the elbow and pushes the elbow out of the device. In order to avoid the clamping plate 19 having an excessively large diameter, which would prevent the limiting block 16 from closing and moving, and thus prevent the slider 13 from being pushed by the cam 12.

[0033] Working principle: The elbow is placed on the support block 402 on one side. The motor 406 operates, controlling the rotation of the second rotating shaft 407 fixedly connected to its output end. This causes the second rotating shaft 407 to rotate the second disc 408 fixedly connected to one end and the limiting post 409 fixedly connected to one side of the second disc 408. When the limiting post 409 rotates to the groove 405 opened in the first disc 404 and enters the groove 405, the limiting post 409 drives the first disc 404 to rotate within the groove 405. This continues until the limiting post 409 leaves the groove 405, at which point the first disc 404 stops rotating. This achieves that for every one rotation of the second disc 408, the first disc 404 drives the first rotating shaft 403 fixedly connected to it to rotate one-quarter of a rotation. This, in turn, drives the rotating disc 401 fixedly connected to one end and the support block 402 fixed to the rotating disc 401. Through two rotations of the second disc 408, the elbow, supported by the support block 402 on one side, rotates. The elbow is conveyed to the other side. At the same time, since the surface of the first thread 5 meshes with the teeth of the first gear 7, the first thread 5 rotates with the first rotating shaft 403, driving the first gear 7 to rotate. Thus, the first gear 7 drives the crossbar 6 fixedly connected to it to rotate. Since the surface of the second thread 8 meshes with the teeth of the second gear 10, the second thread 8 rotates with the crossbar 6, driving the second gear 10 to rotate. Thus, the second gear 10 drives the vertical rod 9 fixedly connected to it to rotate. The cam 12 rotates with the vertical rod 9. The cam 12 rotates its protruding part to push the slider 13, so that the slider 13 can drive the limiting block 16 on one side to move. When the limiting block 16 moves, the limiting groove 17 will push the limiting block 16 to gradually close and clamp the limiting blocks 16 on both sides. Thus, when the clamping plate 19 does not contact the elbow, the clamping plate 19 will move with the limiting block 16 until the clamping plate 19 contacts the elbow and pushes the bending part of the elbow to push the elbow out of the device.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
