Example 1

Referring to fig. 1-2, a gear shaft tool for a gear grinding machine, the gear grinding machine includes a tip 2 for positioning a gear shaft 1, the gear shaft tool includes a fixing ring 3 fixed on the gear shaft 1 and a fixing block 4 fixed on the tip 2, the fixing ring 3 is provided with a connecting block 5 extending along an axial direction thereof, and the fixing block 4 is provided with a connecting mechanism for connecting with the connecting block 5. In this embodiment, two sides of the gear shaft 1 are provided with the apexes 2, one of the apexes is a fixed apex, the other one of the apexes is a movable apex (not shown in the figure), and the movable apex can move along the axial direction, so that the gear shaft 1 can be conveniently taken and placed.

The connecting mechanism comprises two limiting blocks 6 which are respectively arranged on two sides of the connecting block 5, an internal thread hole is formed in each limiting block 6, and a limiting threaded rod 7 is connected to the internal thread of each internal thread hole in an internal thread manner. And rotating the limit threaded rods 7 to enable the two limit threaded rods 7 to move inwards until the two limit threaded rods clamp the connecting block, so that the fixing ring can be connected with the fixing block.

The internal diameter of the fixing ring 3 is matched with the gear shaft 1, and the fixing ring 3 is provided with a positioning jackscrew 8 for positioning. The positioning jackscrew is screwed down, and the fixed connection between the fixed ring 3 and the gear shaft 1 can be realized.

The center 2 is provided with a connecting flange 9, the end face of the fixing block 4 is provided with a fixing hole 10, and the fixing block 4 and the connecting flange 9 are fixedly connected through a fixing bolt arranged in the fixing hole.

In the embodiment, the fixing ring 3 and the gear shaft 1, and the fixing block 4 and the tip 2 are detachably connected, so that the maintenance and replacement of each part are facilitated.

The working principle is as follows: during the use, earlier be fixed in fixed block 4 top 2 on, then will fix fixed ring 3 and be fixed in gear shaft 1 on, when fixing fixed ring 3, make connecting block 5 be located between stopper 6, rotatory limit threaded rod 7 makes limit threaded rod 7 carry on spacing fixed can to connecting block 5, when top 2 is rotatory, stopper 6 is rotatory along with top 2 to drive fixed ring 3, gear shaft 1 along with its synchronous revolution through connecting block 5.
