Specific embodiment
The present invention will be further explained below with reference to the attached drawings (front-rear direction, left and right directions in being described below and up and down
Direction in Fig. 1 front-rear direction, left and right directions and up and down direction it is identical, be only used for that this patent is explained, it is unlimited
Protection scope processed).
As shown in Figure 1, a kind of for detecting the device of keyway symmetry, including pedestal 1, loose piece 3, spring 5,7 and of gauge stand
Dial gauge 9, one 1-1 of mounting rail is equipped on the left of the pedestal 1, and the middle part of loose piece 3 is hinged on peace by pin shaft 4 in the front-back direction
It fills on one 1-1 of beam, the lower end of the lower surface of pedestal 1 and loose piece 3 is in the same plane；The right side of the pedestal 1 is equipped with installation
The beam right free end of two 1-2, two 1-2 of mounting rail is equipped with gauge stand 7, the spy of the dial gauge 9 by screw 1 in the front-back direction
Needle is fixed on downward on gauge stand 7；The right end of the spring 5 is placed in the blind hole of the pedestal 1 below one 1-1 of mounting rail, left end
It is engaged with the lower end of loose piece 3, spring 5 is in compressive state.
The tooling further includes the bolt 1 of the left and right directions above one 1-1 of mounting rail, the screw rod of bolt 1
