Detailed Description

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

It will be apparent that numerous specific details are set forth in the following description in order to provide a thorough understanding of the present utility model, however, the present utility model may be practiced in other ways than as described herein, and therefore the present utility model is not limited to the specific embodiments of the present disclosure.

Referring to fig. 1-3, the present utility model provides a positioning tool for a key slot of a cylindrical grinding machine: including location frock 1, wait two thimble 6 on grinding machine's the axle 4 and the excircle grinding machine, location frock 1 is inside hollow cylindric structure, and its one side is formed with bellied key 2, the inside of axle 4 is hollow structure, keyway 5 has all been seted up to the inner wall both sides of axle 4, and the left and right sides of axle 4 is inserted respectively to the one side that two thimble 6 are close to each other, location frock 1 cup joints the one end at one thimble 6 and is located between axle 4 and thimble 6, and key 2 peg graft in corresponding keyway 5, in this way, can use two location frock 1 to embolia respectively in one side of two thimble 6, then the handheld axle 4 that needs to cut is placed between two thimble 6, then can make two thimble 6 move in opposite directions through control excircle grinding machine, in order to drive two key 2 on two location frock 1 insert respectively in two keyway 5 of axle 4 inner wall, and play the effect of pressing from both sides tight location of axle 4, afterwards, alright begin to grind on the surface of axle 4, this kind of mode of location is compared with traditional heart and presss location and can effectively cut the operation, thereby the efficiency of grinding operation can be accomplished through the clamping of the axle 4 is effective, thereby the efficiency of grinding can be accomplished to the operation is improved.
