[0058] Working principle: First, determine the dimension that this measuring device needs to measure, such as... Figure 14 As shown, this device can measure, in one operation, the result of which is as follows: Figure 14 The positional tolerances of the structural component in two directions are j|0.04|AB and j|0.04|AB.

[0059] Initially, the slide cylinder 117 is in the normally closed state, which in turn causes the upper probe 9, lower probe 11, left probe 8, and right probe 10 to be in a tightened state. Then, the operator places the part to be measured on the measuring table 203 (e.g., Figure 15 (as shown), and insert the left locating pin 202 and the right locating pin 205 into the pin holes of the part being tested, respectively.

[0060] Then the slide cylinder 117 at the bottom of the base plate 102 is started to work, and the slide cylinder 117 drives the shift piece 118 to move when working. Since the shift piece 118 is inserted and matched with the main driving pin 116, the shift piece 118 drives the inner curve cam 115 to rotate through the main driving pin 116 when moving. Since the bottom ends of the upper driving pin 104, the lower driving pin 105, the left driving pin 106 and the right driving pin 107 all extend into the inner curve cavity of the inner curve cam 115, the inner curve cam 115 pushes the upper driving pin 104, the lower driving pin 105, the left driving pin 106 and the right driving pin 107 to stretch out to the outside when rotating.

[0061] The upper driving pin 104, the lower driving pin 105, the left driving pin 106 and the right driving pin 107 are connected with the bottom of each probe rib plate 113, so that the upper driving pin 104, the lower driving pin 105, the left driving pin 106 and the right driving pin 107 move to drive the upper probe 9, the lower probe 11, the left probe 8 and the right probe 10 to stretch out and contact with the inner curve of the measured part under the cooperation of the upper mechanism, the lower mechanism, the left mechanism and the right mechanism.

[0062] Then the left cylinder 201 extends to drive the left stator block 2011 to move to the right, and then the measured part is tightly pushed to the right until the left positioning pin 202 and the right positioning pin 205 respectively abut against the left end of the inner wall of the two pin holes, and the measured data LX1 and RX1 are transmitted to the controller for saving through the left displacement sensor 4 and the right displacement sensor 6.

[0063] Then, the left cylinder 201 is retracted, the right cylinder 206 is extended to drive the right stator block 2061 to move to the left, and then the measured part can be tightly pushed to the left until the left positioning pin 202 and the right positioning pin 205 respectively abut against the right end of the inner wall of the two pin holes, and the measured data LX2 and RX2 are transmitted to the controller for saving through the left displacement sensor 4 and the right displacement sensor 6.

[0064] Then, the right cylinder 206 is retracted, the lower cylinder 208 is extended to drive the lower stator block to move upwards, and then the measured part is tightly pushed upwards until the left positioning pin 202 and the right positioning pin 205 respectively abut against the lower end of the inner wall of the two pin holes, and the measured data UX1 and DX1 are transmitted to the controller for saving through the upper displacement sensor 7 and the lower displacement sensor 5.
