Detailed Description

The following description will explain embodiments of the present invention with reference to the accompanying drawings. As shown in fig. 1 and 2: a fluted disc precision detection device comprises a frame, a lower fluted disc clamp 1 is arranged on the frame, a via hole is arranged at the center of the lower fluted disc clamp 1, a thread bush 2 is arranged on the side surface of the frame, a screw rod 3 is connected with the thread bush 2 in a threaded manner, a crank 4 is arranged at one end of the screw rod 3 positioned outside the frame, the other end of the screw rod 3 is rotatably connected with the side wall of a horizontal moving block 5, a first inclined plane is arranged at one end of the horizontal moving block 5 far away from the screw rod 3,

The fluted disc precision detection device provided by the embodiment of the invention has the following working process: firstly, a pair of fluted discs to be detected is taken, one fluted disc is clamped and fixed through a lower fluted disc clamp 1, the other fluted disc is fixed on an upper fluted disc clamp 8, then the upper fluted disc clamp 8 (together with an upper fluted disc) is tightly pressed at the top end of a mandrel 7 by a pressure plate 9, an operator drives a screw rod 3 to rotate through a crank 4, the screw rod 3 drives a horizontal moving block 5 to horizontally move in an inner cavity of a frame when rotating, when the horizontal moving block 5 retreats, as a first inclined plane at the end part of the horizontal moving block is in sliding connection with a second inclined plane at the bottom end of the mandrel 7 through a matched T-shaped groove and a T-shaped sliding block, the mandrel 7 is pulled to downwards move until the upper fluted disc and the lower fluted disc are mutually meshed, the horizontal height of a detection jig 10 in a regular polygon shape is exactly the same as the horizontal height of an optical measuring head 13 of a self-collimator 12 (namely, detection light rays emitted by the, after the autocollimator 12 is calibrated, the detection operation can be started;

the crank handle 4 is shaken to drive the horizontal moving block 5 to move, and then the mandrel 7 is pushed to drive the upper fluted disc clamp 8 and the first upper fluted discThe upper fluted disc and the lower fluted disc are separated from an occluded state, an operator manually drives the upper fluted disc clamp 8 to rotate a certain angle alpha, the relative position change of the scale pointer 11 relative to the scale ring can be observed during rotation, so that the accuracy of the rotation angle is ensured, after the rotation is in place, the crank 4 is reversely shaken, the upper fluted disc clamp 8 is driven to descend, the upper fluted disc and the lower fluted disc are re-occluded, at the moment, the detection jig 10 falls back to the detection height of the optical measuring head 13 again, because the detection jig 10 is fixedly connected with the upper fluted disc clamp 8 under the action of the pressing plate 9, the detection jig 10 also rotates alpha at the moment, the current side face is detected by using the autocollimator 12, the operation is repeated until all the side faces of the detection jig 10 are detected once, and the angle alpha = of the upper fluted disc clamp 8 rotates every time is finished each time

In actual work, considering the problem that both the working efficiency and the detection precision need to be considered, the value of n is preferably 24, and thus the rotation angle of the upper gear plate clamp 8 is 15 degrees each time.
