Preferably, in the present embodiment, the first elastic member 301c employs a spring.
The unlocking module 302 comprises a rotating block 302a, a second through hole 302a-1 is formed in the rotating block 302a, and a first sliding block 301d is slidably connected in the second through hole 302 a-1; the inner wall of the rotating block 302a is provided with a third sliding groove 302a-2, a third sliding block 301d-4 is slidably connected in the third sliding groove 302a-2, the outer side of the rotating block 302a is fixedly connected with gear teeth 302a-3, and the gear teeth 302a-3 are meshed with the first gear 102c-1b for rotation.
The third chute 302a-2 includes a straight chute 302a-2a and a spiral chute 302a-2b connected end to end, the straight chute 302a-2a being located in a straight line inclined to the axis of the rotating block 302 a; the straight groove 302a-2a is provided with a first groove 302a-2c at one end near the second gear 301e-2, the straight groove 302a-2a is provided with a second groove 302a-2d at one end far from the second gear 301e-2, and the distance from the first groove 302a-2c to the axis of the rotating block 302a, the distance from the spiral groove 302a-2b to the axis of the rotating block 302a, and the distance from the second groove 302a-2d to the axis of the rotating block 302a decrease in order.
Because the gear teeth 302a-3 on the rotating block 302a can be meshed with the first gear 102c-1b, the rotating block 302a rotates to drive the first gear 102c-1b to rotate, so as to drive the dish-shaped bevel gear 102c-1 fixedly connected with the first gear 102c-1b to rotate, and thus drive the clamping blocks 102c-3 to approach each other, and release the flywheel 400.
Specifically, the gear teeth 302a-3 on the rotating block 302a can be set with different numbers of teeth according to actual needs, so as to change the degree to which the clamping block 102c-3 loosens the flywheel 400, and avoid that the flywheel 400 is still clamped by the clamping block 102c-3 or directly falls off from the clamping block 102 c-3.
Specifically, the rotation of the rotating block 302a drives the first gear 102c-1b to rotate in a direction opposite to the direction in which the dish-shaped bevel gear 102c-1 rotates when the flywheel 400 is mounted.
When the second slider 301e pushes the first slider 301d to the farthest position, the third slider 301d-4 starts from the first groove 302a-2c through the straight groove 302a-2a to the second groove 302a-2d, at this time, since the distance from the first groove 302a-2c to the axis of the rotating block 302a is greater than the distance from the spiral groove 302a-2b to the axis of the rotating block 302a, the third slider 301d-4 can only slide along the straight groove 302a-2a and cannot slide along the spiral groove 302a-2 b.
When the first slider 301d moves in a direction approaching the second gear 301e-2 under the elastic force of the first elastic member 301c until the third slider 301d-4 starts from the second groove 302a-2d and passes through the spiral groove 302a-2b to reach the first groove 302a-2c in the process that the first spiral surface 301d-1 contacts the second spiral surface 301e-1, the third slider 301d-4 can only slide along the spiral groove 302a-2b and cannot slide along the straight groove 302a-2a, and the third slider 301d-4 can drive the rotating block 302a to rotate a full circle when sliding in the spiral groove 302a-2b because the distance from the spiral groove 302a-2b to the axis of the rotating block 302a is greater than the distance from the second groove 302a-2d to the axis of the rotating block 302 a.
Referring to fig. 1-16, in use, a worker extends a wrench into square hole 102c-5a to rotate bevel gear 102c-5, and bevel gear 102c-5 rotates to rotate bevel gear 102c-1 as bevel gear 102c-5 rotates in mesh with bevel gear 102 c-1.
Because the flat thread 102c-1a is arranged at one end of the dish-shaped bevel gear 102c-1, the thread latch 102c-2a is arranged at one end of the sliding seat 102c-2, the thread latch 102c-2a is meshed with the flat thread 102c-1a for rotation, the rotation of the dish-shaped bevel gear 102c-1 drives each sliding seat 102c-2 to be away from each other, thereby driving the clamping blocks 102c-3 fixedly connected to the sliding seat 102c-2 to be away from each other, and the clamping blocks 102c-3 are mutually matched to clamp the side wall of the flywheel 400.
When the spindle 101 drives the flywheel 400 to rotate, the driving module 301 rotates along with the flange 102a around the axis of the spindle 101, the second gear 301e-2 rotates around the gear ring 301a due to the fact that the gear ring 301a is fixedly arranged on the base 100, the second gear 301e-2 rotates around the gear ring 301a due to the fact that the second gear 301e-2 is meshed with the teeth on the gear ring 301a to rotate, the second gear 301e-2 rotates around the gear ring 301a in the revolution process, the second gear 301e-2 is fixedly connected with the second slider 301e, the second gear 301e-2 drives the second slider 301e to rotate, and the second slider 301e rotates due to the fact that the first spiral surface 301d-1 is in sliding contact with the second spiral surface 301e-1 and the second slider 301e rotates to drive the first slider 301d to move. Until the second slider 301e rotates once, the first spiral surface 301d-1 and the second spiral surface 301e-1 move to a state of being separated from each other, in the process, the third slider 301d-4 starts from the first groove 302a-2c and passes through the straight groove 302a-2a to reach the second groove 302a-2d, at this time, since the distance from the first groove 302a-2c to the axis of the rotating block 302a is greater than the distance from the spiral groove 302a-2b to the axis of the rotating block 302a, the third slider 301d-4 can only slide along the straight groove 302a-2a and cannot slide along the spiral groove 302a-2 b.
Then, the first slider 301d moves in a direction approaching the second gear 301e-2 by the elastic force of the first elastic member 301c until the first helicoid 301d-1 contacts the second helicoid 301 e-1. In this process, the third slider 301d-4 starts from the second groove 302a-2d and passes through the spiral groove 302a-2b to reach the first groove 302a-2c, and since the distance from the spiral groove 302a-2b to the axis of the rotating block 302a is greater than the distance from the second groove 302a-2d to the axis of the rotating block 302a, the third slider 301d-4 can only slide along the spiral groove 302a-2b and cannot slide along the straight groove 302a-2a, and when the third slider 301d-4 slides in the spiral groove 302a-2b, the rotating block 302a is driven to rotate for a whole circle, and since the gear teeth 302a-3 on the rotating block 302a can mesh with the first gear 102c-1b, the rotating block 302a rotates to drive the first gear 102c-1b to rotate, thereby driving the dish-shaped bevel gears 102c-1 fixedly connected with the first gear 102c-1b to rotate, driving the respective clamping blocks 102c-3 to approach each other, releasing the flywheel 400, thereby facilitating the worker to take off the flywheel, and improving the production efficiency.
