The measurement functions should include dimensional accuracy, positioning accuracy, geometric accuracy and contour accuracy, etc. It can accurately measure the surface contour, roughness, step height and other surface parameters of the workpiece. The measurement process is that when the probe contacts the workpiece and sends a sampling signal, the control system collects the coordinate values ​​of the current three-axis coordinates of the machine tool relative to the machine tool origin, and then the computer system processes the data.

[0027] See also Figure 4 In order to detect the clamping accuracy of the stamping die, the clamping mechanism 4 in this embodiment includes two fixed sleeves 41, a clamping cylinder 42, a rotating sleeve 43, a rotating shaft 44, two clamping claws 45, a connecting frame 46 and a servo motor 47.

[0029] The working principle of the above embodiment is:

[0030] (1) When the precision of the stamping die of automobile parts is tested, the die is first placed on the adjustment plate 37. The adjustment plate 37 supported by the support spring 36 will be tilted by the pressure of the die. Then the user rotates the leveling bolt 35 at the corresponding position according to the tilt of the adjustment plate 37. The leveling bolt 35 is threadedly connected along the threaded sleeve 34 and extends out and abuts the bottom of the adjustment plate 37 to push the adjustment plate 37 to move and keep it level with the rest of the parts. The bubble level 310 can assist in the leveling of the die. The die leveling can keep the die in a horizontal state and connected to the clamping mechanism 4 through the die leveling, and the monitoring accuracy can be adjusted. At the same time, after the leveling is completed, the die is clamped and fixed by the clamping mechanism 4. At this time, the two support plates 382 form a whole and can move synchronously, and then the support plate 382 is pulled upward and moved along the support frame 381 to bring the die out of the adjustment plate 37. Then, the fastening nut 384 is tightened to abut the support frame 381 to lock and limit the position of the support plate 382, ​​so that rotation detection can be achieved during the die precision test.

[0031] (2) When the stamping die is used for clamping accuracy detection, after the stamping die is adjusted and leveled by the leveling mechanism 3, one side of the die contacts with the right clamp 45, and the other side starts the clamping cylinder 42, and the output shaft extends to push the left clamp 45 to move and contact the die, and then the two ends of the die are clamped and fixed by the two clamps 45. Subsequently, the support plate 382 drives the die surface to contact the detection probe of the detector body 2, so that the detector can obtain the die surface accuracy data. The linear module 31 drives the moving detection seat 32 to move linearly left and right, so that the die can be horizontally detected left and right, and the servo motor 47 starts to drive the rotating shaft 44 through the output shaft to drive the clamp 45 to move, thereby driving the clamp 45 and the die to rotate for detection.
