The reinforcing plate of support second slide block is placed between base plate and side plate；
(13) other end connection of the first detection axle is arranged on the end by the first slide block on the supporting plate, again by gripper shoe
On plate；
(14) drive the first slide block to move horizontally, make the first detection axle end depart from shaft coupling, finally by shaft coupling from
The end of the second detection axle is taken off.
Further, described side plate is marked with measures the scale of the described second slide block amount of vertically moving.
Further, described first detection axle is driven to move horizontally by the first slide block described in air cylinder driven.
By such scheme, the detection method of the T-shaped hole axiality of the present invention is simple to operation, during detection, only need to will have
The big nose end having the workpiece of T-shaped hole is enclosed within the second detection axle, by making the first detection axle stretch in aperture, whether cause second
The method that detection axle vertically moves, can determine whether out that T-shaped hole is the most coaxial, and according to the second detection axle amount of vertically moving, detects T
The axiality in shape hole, testing cost is low, and measurement result is the most reliable.
