Brief description of the drawings
Fig. 1 is front view of the present utility model.
Fig. 2 is this Fig. 1 top view.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples：
Referring to Fig. 1-2, a kind of flat key groove symmetry degree gauge, including cubing main body 1, sliding block 2 and amesdial 3 etc..
Referring to Fig. 1, U-shaped chute 11 and V-arrangement locating slot 12 are respectively equipped with two adjacent sides of the cubing main body 1, and
The bottom of V-arrangement locating slot 12 in the middle part of the side wall of U-shaped chute 11 with communicating.
In the present embodiment, the cubing main body 1 is block, and the U-shaped chute 11 is located at the upper surface of cubing main body 1, the U-shaped
The flute length of chute 11 is set along the longitudinal direction, the front end of U-shaped chute 11 insertion.
In the present embodiment, the V-arrangement locating slot 12 is provided with and opened in the left surface of cubing main body 1, the bottom of V-arrangement locating slot 12
Provided with the connected entrance 121 with being communicated in the middle part of the side wall of U-shaped chute 11.
In addition, the sliding block 2 be slidably positioned at in the U-shaped chute 11；The width of sliding block 2 in left-right direction and the U
The groove width of shape chute 11 matches, and the sliding block 2 can slidably reciprocate along the flute length direction (i.e. fore-and-aft direction) of U-shaped chute 11.
In addition, being installed with the middle part of the left surface of sliding block 2 for stretching into the V-arrangement locating slot 12 and with treating to put down on the workpiece of side
Keyway N-1 coordinates the test section 21 of contact, and in detection, the test section 21 can stretch into this and treat on the workpiece of side in flat key groove N-1.
In addition, the amesdial 3 is installed in the cubing main body 1, the lower surface of cubing main body 1, which offers, is vertically passed through the U
Amesdial plug-in opening 13 in shape chute 11, the table bar of the amesdial 3 are inserted into the amesdial plug-in opening 13, in addition the cubing
The screw 14 being passed through in the amesdial plug-in opening is additionally provided with main body 1, lock-screw 15 is installed on the screw 14.Therefore can lead to
Cross and screw the lock-screw 15, and then realize release of the amesdial 3 in the cubing main body 1 or be locked.
In test, the detector of amesdial 3 stretch into the U-shaped chute 11 and with the bottom surface of sliding block 2 (cunning in Fig. 1
The lower surface of block 2) keep abutting.
In addition, it is additionally provided with action bars 4 on the sliding block 2.When sliding block 2 slides back and forth, can be manipulated by means of action bars 4,
It is simple to operate, it is time saving and energy saving.
