In addition, in the description process of the embodiment of the present invention, the position relationships of the devices such as "up", "down", "front", "back", "left", "right" in all the drawings all use fig. 1 as a standard.

As shown in FIG. 1, the gear chamfering tool comprises a base 1 and a platform 2 connected to the top of the base 1 in a rotating mode, wherein:

the device comprises a base 1, a cylindrical supporting upright column 101 is arranged at the top of the base 1, and a supporting base 102 is arranged at the bottom of the base;

the top of the platform 2 is provided with a gear positioning step 21 for supporting a gear to be machined; the bottom is sleeved with a rotary large gear 7 through the outer side of a supporting cylinder 22, and the outer side of the rotary large gear 7 is meshed with a driving small gear 8, so that the driving small gear 8 is driven to rotate through a motor 9, and finally, a gear to be processed placed on the platform 2 is driven to rotate. The motor 9 is fixed on the cylindrical supporting upright 101 through the support 10, and the specific fixing mode can be welding, screw bolt and other detachable connections.

The use method of the gear chamfering tool comprises the following steps: with gear chamfering frock in leveling ground, place the gear through hoist and mount on the gear location step of platform, realize the tang location with the help of gear location step, the workman can sit on the stool, and starter motor drives the rotation of drive pinion, and then the rotation of drive rotatory gear wheel, and then drives the gear revolve on the platform, and then the realization is to the whole upwards chamfer work of carrying out of circumference of gear. That is, after finishing chamfering with a plurality of tooth numbers of the gear, the pedal can be stepped, and the starting motor rotates the gear to the unprocessed area to continue chamfering until finishing the whole circle of chamfering.

In the specific implementation process, the main materials of the gear chamfering tool are common carbon structural steel Q235 and hardening and tempering #45 commonly used in the market.
