[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0025] See also Figure 1-5The present invention provides a technical solution: a multi-axis core rotating shaft structure torque testing device, comprising a workbench 1, with a drive mechanism connected to the workbench 1. A rotating block 2 is connected to one side of the drive mechanism. A circular block 26 is fixedly connected to the top of the rotating block 2. A rotating mechanism is connected to one side of the circular block 26. A fixing mechanism is connected to one side of the rotating mechanism. The circular block 26 has multiple circular grooves 27 formed inside, corresponding to the shaft 4. The fixing mechanism corresponds to the shaft 4. Rotating arms 41 are connected to both sides of the shaft 4. A positioning mechanism is connected to the top of the workbench 1, corresponding to the rotating arms 41. When a worker prepares to perform a torque test on a multi-axis core rotating shaft structure, the worker first needs to accurately insert the shaft 4 into the multiple circular grooves 27 on the top of the circular block 26. The size and number of these circular grooves 27 match the shaft 4, ensuring that the shaft 4 can be securely positioned. The worker then activates the rotating mechanism, which drives the fixing mechanism to move toward the shaft 4. The fixing mechanism can tightly clamp the long block-shaped parts at the upper and lower ends of the shaft 4 from both sides, further enhancing the stability of the shaft 4 during the test. Next, the staff operates the positioning mechanism to move it near the two rotating arms 41, inserts the positioning mechanism into the rotating arms 41, and then operates to fix the rotating arms 41. After all the fixing work is completed, the staff starts the driving mechanism, which drives the rotating block 2 to rotate, thereby driving the circular block 26 and all the shafts 4 on it to start rotating. Although the shaft 4 is rotating, the positioning mechanism at the top and its built-in sensor always remain stationary. The sensor can accurately measure and record the torque value generated by the shaft 4 during the rotation process. The device is provided with a circular groove 27 to first simply fix the shaft 4, and then fix it again through the fixing mechanism, ensuring stability during the torque test. By providing a positioning mechanism to fix the rotating arm 41, it is convenient to rotate the rotating arm 41 for torque testing.
[0026] The rotating mechanism includes a first motor 21, which is fixedly connected to the inside of the rotating block 2, and the output end of the first motor 21 is fixedly connected to the first rotating shaft 22, one side of the first rotating shaft 22 is fixedly connected to the first gear 23, and one side of the first gear 23 is meshedly connected to the second gear 24, and the inside of the second gear 24 is fixedly connected to a swivel 25, the swivel 25 and the round block 26 are rotatably connected, and the swivel 25 and the fixing mechanism are fixedly connected; when it is necessary to start fixing, the staff turns on the first motor 21, so that the first rotating shaft 22 at the output end rotates, and the fixedly connected first gear 23 rotates, thereby rotating the meshed second gear 24. Because the swivel 25 and the second gear 24 are fixedly connected, and the swivel 25 and the round block 26 are rotatably connected, the swivel 25 can rotate, and the rotation of the second gear 24 drives the swivel 25 to rotate, so that the rotating leaves 3 of the fixing mechanism rotate, driving the clamping of the fixing mechanism.
[0027] The fixing mechanism includes a rotating blade 3, the rotating blade 3 and the rotating ring 25 are fixedly connected, and a long rod 31 is connected to one side of the rotating blade 3, and a moving block 32 is connected to one side of the long rod 31. The moving block 32 and the rotating block 2 are slidably connected, and one side of the moving block 32 is fixedly connected to a cross bar 34, and one side of the cross bar 34 is fixedly connected to a clamping block 35, and the clamping block 35 corresponds to the axis 4; when the rotating blade 3 starts to rotate, it moves with the long rod 31, and the long rod 31 moves with the moving block 32. Because the moving block 32 and the rotating block 2 are slidably connected, they can only move in one direction. Therefore, the long rod 31 brings the two moving blocks 32 closer to or away from each other, so that the cross bar 34 and the clamping block 35 also move closer to or away from each other, so that the axis 4 can be fixed and loosened, and the two sides of the axis 4 are fixed, the fixation is more firm, and the overall stability is high.
[0028] The rotating blade 3 and the long rod 31 are rotationally connected, and the long rod 31 and the moving block 32 are rotationally connected; in this way, the long rod 31 can move with the rotation of the rotating blade 3 and move with the moving block 32.
[0029] A slider 33 is provided at the bottom of the moving block 32, and a long groove 28 is provided at the top of the rotating block 2. The slider 33 and the long groove 28 are slidably connected; the slider 33 is inside the long groove 28, just fitting with the long groove 28, and is slidably connected to the long groove 28, which limits the moving block 32 to move only along the direction of the long groove 28, and has only one moving direction, thereby ensuring stability during movement.
[0030] A fixing groove 36 is provided on one side of the clamping block 35, and the size of the fixing groove 36 corresponds to that of the axis 4; when fixing, the fixing groove 36 is close to the long block-shaped parts at the upper and lower ends of the axis 4, and the long block-shaped parts just clamp the fixing groove 36 to achieve better fixation.
[0031] The driving mechanism includes a second motor, which is fixedly connected to the inside of the workbench 1. The output end of the second motor is fixedly connected to the second rotating shaft, and the second rotating shaft and the rotating block 2 are fixedly connected; when the staff turns on the second motor, the second rotating shaft at the output end rotates, and rotates with the rotating block 2, so that the axis 4 at the top rotates, and because the rotating arm 41 is rotatable, the axis 4 rotates, and the rotating arm 41 does not move. Relatively speaking, it is equivalent to the rotating arm 41 rotating, while the axis 4 does not move, so that the torque of the rotating arm 41 can be tested.
[0032] The positioning mechanism includes two push rods 11, which are connected to the workbench 1, and one side of the push rod 11 is connected to block 12 and block 2 13, and the inside of block 2 13 is connected to a bolt 14, and the rotating arm 41 corresponds to block 12 and block 2 13; when the staff wants to fix the rotating arm 41, they push the two push rods 11 to make them move toward the rotating arm 41, and then block 12 and block 2 13 are stuck on the outside of the rotating arm 41. At this time, the staff turns the bolt 14, and block 2 13 moves toward block 1 12, so that the two blocks are tightened and the middle rotating arm 41 is fixed to ensure stability during the rotation test.
[0033] The push rod 11 and the workbench 1 are slidably connected, the block 1 12 and the push rod 11 are fixedly connected, and the block 2 13 and the push rod 11 are slidably connected; the push rod 11 and the workbench 1 are slidably connected, which makes it convenient for the staff to push the push rod 11 to fix the rotating arm 41, and the block 2 13 is also slidably connected, which makes it easy to drive the block 2 13 to slide and realize the clamping of the two blocks.
[0034] The interior of the bolt 14 and the block 2 13 are threadedly connected, and one end of the bolt 14 is connected to the block 1 12; the block 2 13 and the push rod 11 are slidingly connected, so the push rod 11 also limits the block 2 13 from rotating, and when the staff rotates the bolt 14, the block 2 13 should rotate and move with the rotation of the bolt 14, but the rotation is restricted, so the block 2 13 can only move, thereby achieving clamping, and the bolt 14 and the block 1 12 are connected and connected in rotation, ensuring that the bolt 14 can rotate and will not fall off.
[0035] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
