Detailed implementation manner

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] The present invention provides a clamping device for single-row inclined groove bearing testing as shown in Figure 1 - Figure 7 The clamping device includes an operating table 1, an electric chuck 2, and jaws 3 arranged equidistantly on the electric chuck 2. The electric chuck 2 converts the rotational torque into a clamping force through the drive of a motor to fix and clamp the workpiece. The jaws 3 are used to clamp workpieces such as bearings. A non-slip pad is fixedly arranged on the side of the jaws 3 close to the bearing, which enhances the clamping force on the bearing, ensures the stability of the clamping process, and also avoids direct contact between the jaws 3 and the bearing, effectively preventing potential wear on the outer side of the bearing caused by friction.

[0024] A servo motor 407 is fixedly arranged at the bottom of the operating table 1, an electric turntable 408 is fixed on the surface of the operating table 1, the electric chuck 2 is fixedly arranged on the surface of the electric turntable 408, a placing rod 409 is rotatably arranged on the surface of the operating table 1, the placing rod 409 passes through the electric chuck 2 through a sliding hole and is fixed to the output end of the servo motor 407, and a clamping member 410 is slidably arranged on the outer side wall of the placing rod 409. The placing rod 409 is used to place the bearing, and the clamping member 410 is used to clamp the bearing.

[0025] First, compress the clamping member 410 by hand, the spring connected to the inner wall of the clamping member 410 is compressed, then insert the bearing into the clamping member 410, and release the clamping member 410 by hand. At this time, the spring restores its deformation and pushes the clamping member 410 to clamp the inner wall of the bearing.

[0026] The surface of the operating table 1 is provided with a lubrication component for lubricating the bearing during testing. It is mainly used to rotate the clamped bearing during the test after processing, and add an appropriate amount of lubricating oil to the bearing while rotating. This not only saves the cumbersome steps of manual lubricating oil addition by the staff, but also ensures the uniformity and timeliness of the lubrication process, effectively reducing the errors that may be caused by human factors.

[0027] The lubrication component includes a storage tank 401. One side of the storage tank 401 is connected with a feeding port 504, which is convenient for adding lubricating oil into the storage tank. A sealing cover is arranged on the feeding port 504 and can be opened by rotation when lubricating oil needs to be added. The sealing cover is a prior art and will not be elaborated here.

[0028] The storage tank 401 is fixedly arranged on one side of a jaw 3. The storage tank 401 is used to store lubricating oil. A screw rod 402 is rotatably arranged on the inner wall of the storage tank 401. A piston 403 is slidably arranged on the inner wall of the storage tank 401. The piston 403 is threadedly connected with the screw rod 402 through a threaded hole. One end of the screw rod 402 away from the piston 403 is fixedly provided with a first rotating rod 404. One end of the first rotating rod 404 away from the screw rod 402 is fixedly provided with an eccentric wheel 405. The lower end of the storage tank 401 is connected with a discharge pipe 406.

[0029] Considering that the lubricating oil will flow out along the discharge pipe 406 in the storage tank 401, a rotating shaft 411 is rotatably arranged at the end of the discharge pipe 406 away from the storage tank 401. An opening and closing plate 412 is fixedly arranged on the outer side wall of the rotating shaft 411. A torsion spring 6 is sleeved on the outer side wall of the rotating shaft 411. One end of the torsion spring 6 is fixed to the opening and closing plate 412, and the other end of the torsion spring 6 is fixed to the inner wall of the connecting pipe 503. By the rotation of the eccentric wheel 405 driving the screw rod 402 to rotate, the piston 403 is pushed downward along the inner wall of the storage tank, and the lubricating oil is squeezed by the piston 403 and enters the discharge pipe 406. Due to the force of the piston 403 squeezing the lubricating oil downward, the rotating shaft 411 drives the opening and closing plate 412 to rotate, and the torsion spring 6 is compressed. After the opening and closing plate 412 rotates, the lubricating oil flows from the discharge pipe 406 onto the bearing. When the eccentric wheel 405 stops rotating, the screw rod 402 stops rotating, and the torsion spring 6 is reset without the influence of the squeezing force, so that the rotating shaft 411 drives the opening and closing plate 412 to close, thereby preventing the lubricating oil from leaking.

[0030] During operation, first place the bearing on the clamping member 410, and drive the electric chuck 2 so that the jaws 3 clamp the outer wall of the bearing. Then drive the servo motor 407 to rotate. The output end of the servo motor 407 rotates to drive the placement rod 409 to rotate, causing the bearing to rotate. At this time, drive the electric turntable 408 to rotate in the opposite direction to the rotation of the bearing. The eccentric wheel 405 rotates under the influence of the rotation. While the eccentric wheel 405 rotates, it causes the first rotating rod 404 to rotate. The rotation of the first rotating rod 404 drives the screw rod 402 to rotate. The rotation of the screw rod 402 causes the piston 403 to slide downward along the inner wall of the storage tank 401. While the piston 403 slides downward, it squeezes the lubricating oil, causing the lubricating oil to flow out along the discharge pipe 406, thus realizing the operation of automatically adding lubricating oil when clamping the bearing.

[0031] Considering that there may be an overflow phenomenon when adding lubricating oil to the bearing, in order to avoid waste caused by the overflow, a recovery tank 501 is rotatably connected to the surface of the electric chuck 2 through a threaded groove. When it is necessary to reuse the lubricating oil in the recovery tank 501, the recovery tank 501 can be rotated out by rotation, and the lubricating oil in the recovery tank 501 can be poured out.

[0032] Furthermore, a scraper 502 is fixedly arranged on the outer side wall of the discharge pipe 406. The side of the scraper 502 facing the discharge pipe 406 is inclined. When the scraper 502 contacts the outer side of the bearing, it spreads and evenly applies the lubricating oil on the bearing, and collects the excess lubricating oil into the scraper 502.

[0033] A connecting pipe 503 is connected to the inner wall of the scraper 502. One end of the connecting pipe 503 is communicated with the recovery tank 501. The electric chuck 2 rotates, thereby driving the recovery tank 501 and the discharge pipe 406 to rotate together. During this process, the scraper 502 can evenly apply the lubricating oil flowing out of the discharge pipe 406 on the bearing, ensuring that the bearing is fully lubricated. At the same time, the scraper 502 can also effectively scrape off the excess lubricating oil, causing it to flow into the recovery tank 501 through the connecting pipe 503, avoiding waste and pollution of the lubricating oil.
