Description

Technical Field

[0001] This utility model relates to the field of half-shaft gear grinding technology, specifically to a half-shaft gear external cylindrical grinding device. Background Technology

[0002] The half-shaft gear is the transmission shaft that transmits torque between the differential and the drive wheel. One end of it is usually connected to the half-shaft gear through a spline, and the other end is connected to the wheel hub. After the half-shaft gear is machined, the tooth grooves of the gear need to be precision machined to improve the meshing degree between the gears, thereby increasing the service life of the gear set. For this purpose, a grinding device is required.

[0003] Traditional grinding devices still have some shortcomings. Since the grinding wheel is fixed to the output shaft of the motor with bolts, and the tooth grooves of different half-shaft gears are different, when grinding half-shaft gears of different sizes, the operator needs to use tools to loosen the bolts and remove the grinding wheel for replacement. The operation is time-consuming and laborious, and it also reduces the efficiency of replacing the grinding wheel, thus reducing the practicality of the grinding device. To address this, we propose a half-shaft gear external cylindrical grinding device. Utility Model Content

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 protection scope of the present utility model.

[0023] Example 1:

[0024] Please see Figures 1-5In this embodiment of the utility model, the half-shaft gear external cylindrical grinding device includes: a machine base 1 and two grinding wheels 9. The top of the machine base 1 is connected to a frame 2. A transverse groove is opened on the top of the inner wall of the frame 2. A moving mechanism 3 is provided on one side of the frame 2, and the moving mechanism 3 extends into the interior of the transverse groove.

A mounting frame 5 is connected to the top of the machine base 1.

A driving mechanism 7 is provided on the top of the inner wall of the machine base 1, and the driving mechanism 7 extends to the top of the machine base 1 and meshes with the rotating mechanism 6.

[0025] Specifically, after the half-shaft gear is fixed by the rotating mechanism 6, the drive mechanism 7 is then activated to drive the rotating mechanism 6 to rotate the half-shaft gear intermittently. At this time, the moving mechanism 3 is activated to drive the two locking mechanisms 4 to move closer to each other, causing the two grinding wheels 9 to engage with the two tooth grooves of the half-shaft gear. Then, the two locking mechanisms 4 are activated, which will drive the two grinding wheels 9 to rotate, thereby grinding the two tooth grooves of the half-shaft gear. Finally, the two locking mechanisms 4 can be used to disassemble and install the two grinding wheels 9, making it convenient to grind the tooth grooves of half-shaft gears of different sizes.

[0026] Example 2:

[0027] Please see Figures 3-4In this embodiment of the present invention, the half-shaft gear external cylindrical grinding device includes a moving mechanism 3 comprising a bidirectional threaded rod 301, two threaded blocks 302, two frames 303, and a forward and reverse motor 304. The bidirectional threaded rod 301 is rotatably connected between the two sides of the inner wall of the transverse groove. The two threaded blocks 302 are threadedly connected to the outer surface of the bidirectional threaded rod 301. The two frames 303 are respectively connected to the bottom of the two threaded blocks 302. The forward and reverse motor 304 is connected to one side of the frame 2, and one end of the bidirectional threaded rod 301 extends to one side of the frame 2 and is connected to one end of the output shaft of the forward and reverse motor 304. The locking mechanism 4 includes a drive motor 401, a connecting rod 402, a baffle 403, and a first annular insert rod 404. The drive motor 401 is connected to the back of the inner wall of one of the frames 303. The connecting rod 402 is connected to one end of the output shaft of the drive motor 401. The baffle 403 is connected to the connecting rod 402. On the outer surface, the first annular insert 404 is connected to the back of the baffle 403. The locking mechanism 4 also includes a rotating rod 405, a sliding groove 406, a sliding plate 407, a second annular insert 408, a spring 409, and a fixed plate 410. The rotating rod 405 is rotatably connected to the front of the inner wall of one of the frames 303. The sliding groove 406 is opened on the outer surface of the rotating rod 405. The sliding plate 407 is slidably connected to the inside of the sliding groove 406 and is fitted on the outer surface of the rotating rod 405. The second annular insert 408 is connected to one side of the sliding plate 407. The fixed plate 410 is fixedly connected to the outer surface of the rotating rod 405. The spring 409 is connected between the fixed plate 410 and the sliding plate 407 and is located outside the rotating rod 405. One end of the first annular insert 404 and the second annular insert 408 are respectively movably inserted into the inside of two annular holes on both sides of one of the grinding wheels 9.

[0028] Specifically, after the axle gear is fixed on the outer surface of the gear positioning rod 601, the output shaft of the forward and reverse motor 304 is started to drive the bidirectional threaded rod 301 to rotate, causing the two threaded blocks 302 to move threadedly and drive the two frames 303 to move closer to each other. This, through the two locking mechanisms 4, drives the grinding wheel 9 to approach the tooth groove of the axle gear. The output shaft of the drive motor 401 is started to drive the baffle 403 to rotate through the connecting rod 402. The baffle 403 is inserted into one of the annular grooves, thereby driving the grinding wheel 9 to rotate. This allows the grinding wheel 9 to grind the axle gear, and in conjunction with another grinding wheel 9, grinds the two tooth grooves of the axle gear. When the grinding wheel 9 needs to be replaced, simply pull the sliding plate 4. 07 slides on the outer surface of the rotating rod 405 and compresses the spring 409. At the same time, the sliding plate 407 will drive the second annular insert 408 to withdraw from the annular insertion hole on one side of the grinding wheel 9, releasing the lock on the grinding wheel 9. At this time, the grinding wheel 9 can be slid out from the outer surface of the first annular insert 404, thus completing the disassembly of the grinding wheel 9. The replaced grinding wheel 9 is then re-sleeved onto the outer surface of the connecting rod 402, and the first annular insert 404 is inserted into one of the annular insertion holes of the grinding wheel 9. The sliding plate 407 is released, and the spring 409 will return to its original position, driving the second annular insert 408 to re-insert into the annular insertion hole on one side of the grinding wheel 9, thus completing the fixation of the grinding wheel 9 and completing the replacement of the grinding wheel 9.

[0029] Example 3:

[0030] Please see Figures 1-5 In this embodiment of the utility model, the half-shaft gear external cylindrical grinding device includes a rotating mechanism 6 comprising a gear positioning rod 601 and a first gear 602. The gear positioning rod 601 is rotatably connected between the top of the machine base 1 and the top of the inner wall of the mounting frame 5, and the top end of the gear positioning rod 601 extends to the top of the mounting frame 5. The first gear 602 is connected to the outer surface of the gear positioning rod 601. The driving mechanism 7 includes an intermittent motor 701, a connecting rod 702, and a second gear 703. The intermittent motor 701 is connected to the top of the inner wall of the machine base 1. The connecting rod 702 is rotatably connected to the top of the machine base 1, and the bottom end of the connecting rod 702 extends into the interior of the machine base 1 and is connected to one end of the output shaft of the intermittent motor 701. The second gear 703 is connected to the top end of the connecting rod 702, and the second gear 703 meshes with the first gear 602. A door 8 is hinged to one side of the machine base 1.

[0031] Specifically, the reverse motor 304 drives the two grinding wheels 9 to move in opposite directions. Then, the intermittent motor 701 is started, and its output shaft drives the second gear 703 to rotate through the connecting rod 702. The second gear 703 drives the first gear 602 to rotate the gear positioning rod 601, causing the fixed half-shaft gear to rotate at a certain angle. After that, the intermittent motor 701 stops, and the drive motor 401 is started again to drive the two grinding wheels 9 to move closer to each other, so that the other two tooth grooves of the half-shaft gear can be ground. The machine door 8 allows for inspection of the inside of the machine 1.

[0032] The working principle of this utility model is as follows: First, the shaft sleeve of the half-shaft gear to be ground is placed on the outer surface of the gear positioning rod 601 and fixed with external tools. Then, the forward and reverse motor 304 is started. The output shaft of the forward and reverse motor 304 drives the bidirectional threaded rod 301 to rotate, causing the two threaded blocks 302 to move threadedly on the outer surface of the bidirectional threaded rod 301, and driving the two frames 303 to move closer to each other. Thus, through the two locking mechanisms 4, the grinding wheel 9 is driven to approach the tooth groove of the half-shaft gear. Then, the drive motor 401 is started. The output shaft drives the baffle 403 to rotate via the connecting rod 402. The baffle 403 is inserted into one of the annular grooves, which in turn drives the grinding wheel 9 to rotate. This allows the grinding wheel 9 to grind the half-shaft gear. In conjunction with another grinding wheel 9, it can simultaneously grind both tooth grooves of the half-shaft gear. When the grinding wheel 9 needs to be replaced, simply pull the sliding plate 407 to slide on the outer surface of the rotating rod 405, compressing the spring 409. Simultaneously, the sliding plate 407 will drive the second annular insert rod 408 from one side of the annular groove of the grinding wheel 9. Withdraw the socket to release the lock on the grinding wheel 9. Then slide the grinding wheel 9 out of the outer surface of the first annular insert 404 to complete the disassembly of the grinding wheel 9. Replace one side of the replaced grinding wheel 9 onto the outer surface of the connecting rod 402, and insert the first annular insert 404 into one of the annular sockets of the grinding wheel 9. Release the slide plate 407, and the spring 409 will return to its original position, causing the second annular insert 408 to re-insert into the annular socket on one side of the grinding wheel 9, thus fixing the grinding wheel 9 in place and completing the replacement of the grinding wheel 9. After the two tooth grooves of the half-shaft gear are ground, the forward and reverse motor 304 is started in reverse to drive the two grinding wheels 9 to move in opposite directions. At this time, the output shaft of the intermittent motor 701 is started to drive the second gear 703 to rotate through the connecting rod 702. This causes the second gear 703 to drive the first gear 602 to rotate the gear positioning rod 601, thereby causing the fixed half-shaft gear to rotate a certain angle. Then the intermittent motor 701 stops, and the drive motor 401 is started again to drive the two grinding wheels 9 to move closer to each other, so that the other two tooth grooves of the half-shaft gear can be ground.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
