[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0017] like Figures 1-6 As shown, the present invention provides the following technical solutions: Example 1: A new energy vehicle tooth chamfering device includes a fixing base 1, a lifting device is fixedly installed on the lower surface of the fixing base 1, a lifting sleeve 2 is fixedly installed on the lifting device, and a grinding device is fixedly installed on the inner wall of the lifting sleeve 2; A mounting groove 3 is provided on the fixing seat 1, and a support rod 4 is fixedly installed in the mounting groove 3. The upper end of the support rod 4 is provided with a thread and is threadedly connected to a grinding plate 5. The lower surface of the grinding plate 5 is provided with a threaded groove and is threadedly connected to the upper end of the support rod 4. A rotating sleeve 6 is rotatably connected to the support rod 4, and a rotating disk 7 is fixedly installed on the rotating sleeve 6. The rotating disk 7 is provided with a plurality of placement grooves 8, and a through hole 9 is provided on the grinding plate 5. A driving device is fixedly installed in the mounting groove 3, and the thread locking direction of the grinding plate 5 is consistent with the rotation direction of the rotating disk 7; The grinding device includes a plurality of support bars 10, which are fixedly mounted on the inner wall of the lifting sleeve 2. The support bars 10 are rotatably connected to a V-shaped grinding bar 11 via a rotating shaft. A fixing plate 12 is fixedly connected to the outer side walls of both sides of the V-shaped grinding bar 11. A plurality of springs 13 are fixedly connected between the fixing plate 12 and the lifting sleeve 2. The lifting device includes a cylinder 14, which is fixedly mounted on the lower surface of the fixed base 1. The output end of the cylinder 14 is movably connected to a piston rod 15, and the lower end of the piston rod 15 is fixedly connected to a support frame 16, which is fixedly connected to the lower surface of the lifting sleeve 2; The driving device includes a motor 17, which is fixedly installed in the mounting groove 3. The output end of the motor 17 is fixedly connected to a driving wheel 18 through a coupling, and the driving wheel 18 abuts against the outer wall of the rotating sleeve 6; When in use, the following steps are included: In the first step, the motor 17 is started, and the motor 17 drives the driving wheel 18 to rotate. The driving wheel 18 drives the rotating sleeve 6 to rotate by contacting with the rotating sleeve 6. The rotating sleeve 6 rotates in place under the limit of the support rod 4, and the rotating sleeve also drives the rotating disk 7 to rotate synchronously. When the placement slot 8 is aligned with the through hole 9, the motor 17 is stopped so that the notch of the placement slot 8 is aligned with the through hole 9. Then, the rotating disk 7 is manually pushed to drive the placement slot 8 to fine-tune so that the placement slot 8 and the through hole 9 completely overlap. In the second step, when the motor 17 stops and the placement slot 8 is completely aligned with the through hole 9, a gear that matches the size of the placement slot 8 is placed into the placement slot 8 through the through hole 9, and the teeth of the gear are engaged with the V-shaped grinding strip 11. Then, the motor 17 is started to drive the rotating disk 7 to rotate, and gears of the same specifications are placed in several placement slots 8 in turn according to the operation in the first step. The third step is to start the cylinder 14, which drives the piston rod 15 to move back and forth. The piston rod 15 drives the support frame 16 to move synchronously. The support frame 16 drives the lifting sleeve 2 to move back and forth. The lifting sleeve 2 drives the V-shaped grinding strip 11 to move synchronously through the support strip 10. The V-shaped grinding strip 11 grinds the teeth of the gear stuck in it. In the fourth step, the motor 17 is started to drive the rotating disk 7 to rotate continuously, and the rotating disk 7 drives the gear to move synchronously. The gear is limited by the V-shaped grinding strips 11, so that when the gear is driven to rotate by the rotating disk 7, the gear will rotate in the placement groove 8. When the gear is driven to rotate and move by the rotating disk 7, the gear teeth will roll in the plurality of V-shaped grinding strips 11, and the reciprocating V-shaped grinding strips 11 will grind the gear teeth; In the fifth step, when the gear is engaged with the V-shaped grinding strip 11, the V-shaped grinding strip 11 is connected to the support bar 10 by rotating through the rotating shaft, and the spring 13 pulls the V-shaped grinding strip 11 to move to the middle position. When the gear contacts the V-shaped grinding strip 11, the teeth of the gear will first be inserted into the V-shaped grinding strip 11. Since the V-shaped grinding strip 11 can rotate, the V-shaped grinding strip 11 will be inclined toward the teeth of the gear and tightly against the teeth of the gear. As the gear moves, the direction is adjusted in real time to keep against it, and after the offset is released, it is pulled back to the position by the spring 13, thereby facilitating subsequent processing. In the sixth step, when the gear rotates, the upper surface of the gear will be ground against the lower surface of the grinding plate 5 for grinding, and the lower surface of the gear will be ground against the bottom of the placement groove 8 for grinding, so that the upper and lower surfaces of the gear will be ground at the same time as the teeth are ground; Step 7: After the gear grinding is completed and the placement groove 8 coincides with the through hole 9, the motor 17 is stopped, and then the first step can be repeated, and the gears are taken out one by one to complete the grinding of the gears; Step 8. After a period of use, the grinding plate 5 can be removed by rotating it, and then the rotating sleeve 6 and the rotating disk 7 can be removed. At this time, the grinding plate 5 and the rotating disk 7 can be replaced, and the internal equipment can be maintained to avoid failure after long-term use.

[0018] Embodiment 2: The technical solutions of this embodiment that differ from those of embodiment 1 include: A sliding groove 19 is provided on the outer wall of the fixed seat 1, and a slider 20 is slidably connected in the sliding groove 19. One end of the slider 20 extends to the outside of the fixed seat 1 and is fixedly connected to the inner wall of the lifting sleeve 2. Through the cooperation of the sliding groove 19 and the slider 20, the lifting sleeve 2 is limited so that the lifting sleeve 2 can only be lifted vertically. Several V-shaped grinding strips 11 are arranged vertically, and several V-shaped grinding strips 11 are arranged in a circular shape about the rotating disk 7, so that when the gear is driven to rotate by the rotating disk 7, the teeth of the gear will roll in the several V-shaped grinding strips 11, the lower surface of the grinding plate 5 is provided with silicon carbide, and the bottom of the placement groove 8 is provided with silicon carbide. When the gear rotates, the upper surface of the gear will be against the lower surface of the grinding plate 5 for grinding, and the lower surface of the gear will be against the bottom of the placement groove 8 for grinding. The axial center lines of the fixed seat 1, the lifting sleeve 2 and the rotating disk 7 are arranged to coincide.
