The specific working process of the invention is as follows:

(1) fastening of the gear body 10

First, when it is required to grind the gear body 10, the gear body 10 is placed on the fixing bar 8, because the fixing rod 8 is in the shape of an upper letter, the fixing rod 8 can support the gear body 10, the hydraulic lever 2 is then opened, the hydraulic lever 2 moves the grinding head 23 downwards, so that the first rope 12 is pulled, so that the first rope 12 on the connecting rod 3 drives the connecting rod to rotate on the workbench 1, and then make the movable frame 7 with connecting rod 3 threaded connection slide on workstation 1 to make dead lever 8 fix tightly to gear body 10, dead lever 8 and regulating block 9 block together this moment, torsion spring 5 takes place compression deformation, and movable frame 7 and protection frame 18 magnetic adsorption are in the same place (it should be noted that, the magnetic force between movable frame 7 and the protection frame 18 is greater than the frictional force between movable frame 7 and the connecting rod 3).

(2) Jacking up the gear body 10

When the connecting rod 3 rotates, the first bevel gear 6 is driven to rotate, so that the second bevel gear 19 meshed and connected with the first bevel gear 6 rotates in the protective frame 18, under the simultaneous rotation of the 2 groups of adjusting rods 20, the adjusting rods 20 cannot drive the adjusting blocks 9 to rotate, the adjusting rods 20 in threaded connection with the shaft ends of the second bevel gear 19 ascend, the adjusting blocks 9 drive the fixing rods 8 to slide upwards in the moving frame 7, the relative moving speed between the gear body 10 and the grinding head 23 is increased, and the machining efficiency of the gear body 10 is improved.

(3) Screening for rotation of gear body 10

When first rope 12 upwards pulls, because ratchet bull stick 16 can only unidirectional rotation, thereby make first rope 12 can not drive ratchet bull stick 16 and rotate (need to matter, ratchet bull stick 16 is the transfer line of installing the ratchet structure, and the ratchet structure belongs to prior art, therefore do not detailed description in this application), after gear body 10 ground one section, hydraulic stem 2 upward movement, under the effect that torsion spring 5 resumes deformation, can make first rope 12 automatic by the rolling, and then drive ratchet bull stick 16 and rotate, second rope 15 is pulled this moment, thereby make second rope 15 drive regulating block 9 rotate, and then dead lever 8 rotates in removing frame 7, and drive gear body 10 and rotate.

In summary, the following steps: the gear body 10 jacking device has the beneficial effects that the gear body 10 can be jacked up while the gear body 10 is fixed, so that the relative movement rate between the gear body 10 and the grinding head 23 is increased, and the machining efficiency of the gear body 10 is improved.

The device can also make the regulating block 9 drive the gear body 10 to rotate through the transmission of the first rope 12 and the second rope 15, thereby reducing the maintenance efficiency when the whole device breaks down and reducing the manufacturing cost of the whole device.
