Description

Technical Field

[0001] The present invention relates to the technical field of gear testing, and in particular to a quality inspection device for gear production. Background Art

[0002] Gears are mechanical components with teeth on the rim that can continuously mesh to transmit motion and power. During the development and production of gears, the first batch of gears need to undergo a series of tests, such as size, thickness, pitch, and violence tests, to obtain gear quality data. However, the service life test of gears is relatively simple. Generally, the test is carried out by driving the gear transmission, which is relatively simple. Because the structure driven by the gear is not necessarily a structure with uniform weight distribution, uneven weight distribution will cause uneven force on the gear when it rotates, and uneven force on the gear will cause damage to the stressed part. Therefore, life testing under uneven force conditions is also an indispensable testing link. Summary of the invention

[0046] The gear installation mechanism automatically installs and disassembles the test gear, which not only solves the problems caused by manual installation, but also makes the installation and replacement of the test gear more convenient.

[0047] A driving mechanism 5, which is installed on the supporting mechanism 1, and is used to drive the eccentric weight rotation testing mechanism 2, the eccentric weight adjustment mechanism 3 and the gear installation mechanism 4 to operate respectively;

[0048] The driving mechanism 5 includes a motor 51 fixed to one side of the support plate 13, and a long gear 52 is fixed to one end of the output shaft of the motor 51. One side of the long gear 52 is meshed with the one-way gear 1 32, and the other side is meshed with the one-way gear 2 418. The one-way gear 3 414 moves to mesh with the long gear 52.

[0049] A controller is fixed on one side of the support plate 13 , and the controller is electrically connected to the motor 51 and the plurality of electromagnets 36 .

[0050] Working principle:

[0051] First, by starting the detection program, the biased weight intensity and biased weight position are selected, and then the controller starts the motor 51 to drive the long gear 52 to rotate. The rotation of the long gear 52 satisfies the direction of the one-way gear 32 driving the reciprocating screw 31 to rotate, so that the movable plate 39 drives the multiple counterweight blocks 37 to move, so that the multiple counterweight blocks 37 are all inserted into the interior of the multiple counterweight slots 22. Before insertion, the insertion rod 34 will be inserted into the interior of the pull frame 25. When inserting, the slope 35 will first contact the pull frame 25. When continuing to insert, because the height of the insertion rod 34 is higher than the pull frame 25, continuing to insert the insertion rod 34 will cause the pull frame 25 to pull the pull rod 24 and the limit block 26 upward along the slope 35 to move the extrusion spring 28, and then The counterweight 37 is inserted into the hidden groove 23, and then the counterweight 37 is completely inserted into the hidden groove 23. After the insertion, the controller closes the designated electromagnet 36 according to the biased weight strength and biased weight position, and the moving plate 39 moves to the thread tail of the reciprocating screw 31 and then moves back. The electromagnet 36 that is not closed pulls the sucked counterweight 37 out of the counterweight groove 22, and the electromagnet 36 that is closed retains the counterweight 37 in the counterweight groove 22. The insertion rod 34 follows the movement to pull out the pull frame 25, and then the spring 28 pushes the limit block 26 to insert into the limit groove 38. After the moving plate 39 moves to the thread tail of the reciprocating screw 31, the motor 51 is started to drive the long gear 52 to reverse and perform a biased weight rotation simulation test.

[0052] The long gear 52 is reversed to meet the direction of the one-way gear 2 418 driving the shaft 2 416 to rotate. The shaft 2 416 is connected to the sleeve 413 in rotation, so the sleeve 413 is not allowed to rotate with it. The shaft 2 416 rotates to drive the gear 417 to rotate, and the gear 417 drives the test gear 45 to rotate. The test gear 45 drives the shaft 1 27 to rotate through the annular oil shell 41 and the positioning block 42. The rotation of the shaft 1 27 drives the circular plate 21 and the internal counterweight block 37 to rotate. The counterweight block 37 will change the weight of a certain part of the circular plate 21, so when the circular plate 21 rotates, the circular plate 21 will be overweight. The overweight will cause the test gear 45 to be unevenly stressed during the rotation process, thereby extending the service life of the test gear 45 under uneven stress, thereby simulating the service life of the gear when driving the overweight structure to rotate. When you want to increase the counterweight or change the position of the overweight, you can drive the movable plate 39 to move again, put in or pull back the counterweight block 37, and simulate the influence of different overweight conditions on the gear.

[0053] When the moving plate 39 moves, it pulls the rotating shaft 2 416 to move, and the movement of the rotating shaft 2 416 drives the one-way gear 2 418 and the gear 417 to move, and at the same time pulls the sleeve 413 to move, and the sleeve 413 drives the slider 1 412 to slide inside the slide groove 1 411, and drives the one-way gear 3 414 to move and mesh with the long gear 52. When moving, because the long gear 52 is rotating, when the teeth of the one-way gear 3 414 collide with the teeth of the long gear 52, they cannot mesh with the long gear 52, and the blocked one-way gear 3 414 cannot continue to move. When the long gear 52 is moved, the spring 2 420 is compressed. When the teeth of the long gear 52 and the one-way gear 3 414 are staggered, the stored force of the spring 2 420 is released, instantly pushing the one-way gear 3 414 to move and mesh with the long gear 52. However, the forward rotation of the long gear 52 driven by the motor 51 does not satisfy the direction of rotation of the sleeve 413 driven by the one-way gear 3 414. The one-way gear 2 418 moves with the rotating shaft 2 416 and is disengaged from the long gear 52, and the gear 417 is disengaged from the test gear 45. Therefore, when the test gear 45 needs to be replaced, the motor 51 is started to drive the long gear 52 to rotate forward, which does not meet the direction of rotation of the sleeve 413 driven by the one-way gear 3 414. The gear 52 is reversed, so that the long gear 52 drives the one-way gear three 414 and the sleeve 413 to rotate. The sleeve 413 rotates through the slider 1 412 to drive the reciprocating screw 2 49 to rotate, so that the moving frame 410 moves on the reciprocating screw 2 49. When it is away from the rotating shaft 1 27, the moving frame 410 will pull the magnet 48, the push rod 47 and the piston 46 to move, and the oil in the annular oil shell 41 is pumped back into the oil chamber 43. Then the positioning block 42 contracts to release the squeezing of the test gear 45. When the piston 46 moves to the end, it cannot pull the piston 46 to continue moving. When the test gear 45 is installed, the test gear 45 is inserted into the gap and fixed in position by the positioning block 42. After the installation is completed, the motor 51 is started to drive the long gear 52 to rotate forward to reset the various structural parts. When resetting, if the one-way gear 2 418 is in contact with the long gear 52, the spring 3 422 will be compressed to drive the slider 3 to slide in the slide groove 3. When the teeth are staggered, the spring 3 422 will push the one-way gear 2 418 to re-engage with the long gear 52, and the reset is completed.

[0054] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
