Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 - Figure 3The utility model provides an embodiment: a grinding device for processing a reducer, comprising a grinder 1 for grinding the inner wall of the reducer, the grinder 1 is a prior art, and can start working by starting the power supply. Due to the prior art, this case will not be described in detail. An electric telescopic rod 2 for driving the slide rail 3 to move up and down is installed on the top of the grinder 1, and a slide rail 3 for supporting a sliding plate 5 is installed on the top of the electric telescopic rod 2. The right end of the slide rail 3 is fixedly connected with a fixed plate 4 for fixing the reducer, and the rear end of the slide rail 3 passes through and is slidably connected with a sliding plate 5 for cooperating with the fixed plate 4 to fix the reducer. The two sides of the reducer can be fixed by moving the sliding plate 5 and cooperating with the fixed plate 4 at the same time, and the rear end of the fixed plate 4 is fixedly connected with a steel cable 8 for driving the pressure plate 6 to move, and the outer The wall is sleeved with a pressure plate 6 for reinforcing and fixing the reducer. When both sides of the reducer are fixed, the pressure plate 6 can be used to squeeze its outer wall so that it is fixed to the rear end of the slide rail 3. The steel cable 8 passes through and is inserted into the rear end of the sliding plate 5. The front end of the sliding plate 5 is installed with a locking assembly 7 for fixing the sliding plate 5 and the steel cable 8. The locking assembly 7 includes a bracket 71 for supporting the winding shaft 72. The rear end of the bracket 71 is fixedly connected to the front end of the sliding plate 5. When the sliding plate 5 moves, the bracket 71 will be driven to move synchronously. The steel cable 8 passes through and slides on the rear end of the bracket 71. The right end of the bracket 71 is rotatably connected to a winding shaft 72 for winding the steel cable 8. The rear end of the steel cable 8 is fixedly connected to the outer wall of the winding shaft 72. The steel cable 8 can be driven to wrap around the outer wall of the winding shaft 72 by rotating the winding shaft 72.

[0032] Reference Figure 1 - Figure 3 The right end of the winding shaft 72 is fixedly connected with a bevel gear 10 for driving the winding shaft 72 to rotate, the rear end of the bracket 71 is fixedly connected with a bevel gear 29 for driving the bevel gear 10 to rotate, and the rear end of the bevel gear 29 is fixedly connected with a turning handle, and the bevel gear 29 can be driven to rotate by rotating the turning handle. The bevel gear 29 is meshed with the bevel gear 10, and the bevel gear 10 can be driven to rotate when the bevel gear 29 rotates. The right end of the winding shaft 72 is fixedly connected with a rotating wheel 76 for fixing the winding shaft 72, and the outer wall of the rotating wheel 76 is provided with a The locking groove 77 of the locking block 78 is slidably connected to the inner wall of the bracket 71 with a locking block 78 for fixing the rotating wheel 76. The locking block 78 and the locking groove 77 are adapted to each other, and the top of the locking block 78 is set as an inclined surface. When the rotating wheel 76 drives the steel cable 8 to reel up, the inclined surface at the top of the locking block 78 will be squeezed to force it to move forward. However, when the rotating wheel 76 tries to rotate in the opposite direction, the locking block 78 will be stuck in the locking groove 77 so that the rotating wheel 76 cannot rotate. The rear end of the locking block 78 is fixedly connected to a locking spring 79 for pushing the locking block 78 backward.

[0033] Reference Figure 1 - Figure 3The rear end of the bracket 71 passes through and is slidably connected with a block 74 for fixing the bracket 71. The rear end of the slide rail 3 is provided with a fixing groove 711 for accommodating the block 74. The fixing groove 711 and the block 74 are adapted. The right end of the block 74 is provided with an inclined surface. When the sliding plate 5 drives the bracket 71 to move to the right, it squeezes the inclined surface of the right end of the block 74 to force it to move forward. When the bracket 71 tries to move to the left, the block 74 will be stuck in the fixing groove 711 so that the bracket 71 cannot move. The front end of the block 74 is fixedly connected with an adjusting spring 75 for driving the block 74 to move backward. The inner wall of the frame 71 is fixedly connected with a block 710 for supporting the adjusting spring 75 and the locking spring 79.

The locking block 74 and the locking block 78 can be driven forward by pushing the unlocking block 73 forward. When the locking block 74 and the locking block 78 move forward, they will not contact the unlocking block 73, and thus cannot drive the unlocking block 73 to move.

[0034] Working principle: when it is necessary to fix the reducer, the reducer can be placed in the middle of the sliding plate 5 and the fixed plate 4 first, and then the electric telescopic rod 2 can be adjusted to adjust the slide rail 3 and the fixed plate 4 to a suitable height, and then the sliding plate 5 can be pushed to the right to drive the sliding plate 5 to move to the right to push the reducer so that it is fixed at the left end of the fixed plate 4, and then the handle can be rotated to drive the bevel gear 2 9 to rotate, and the bevel gear 2 9 will drive the bevel gear 1 10 to rotate, and the bevel gear 10 will drive the winding shaft 72 to rotate, and when the winding shaft 72 rotates, it will drive the steel cable 8 to wrap around its outer wall, and the steel cable 8 will drive the pressing plate 6 to squeeze the rear end of the reducer and fix the reducer to the rear end of the slide rail 3. At this time, the reducer will be completely fixed and cannot move, and then the grinder 1 can be started to start grinding it.
