A release automatic locking switch 21 is arranged outside the return spring 20.

[0024] Specifically, as Figure 1 shown, when the machine tool stops working, the workpiece can be measured. Taking the inner and outer diameters as an example of the inner diameter, first place the movable measuring head 12 on the inner hole, apply a little force to make it in a compressed state. At this time, one end of the fixed measuring head 10 can be placed into the inner hole. Then, there is no need to press the movable measuring head 12 forcefully, just let it be in a free state. At this time, the reading can be observed on the dial indicator, but it may not be the actual size. It is necessary to slightly shake the measuring tool up and down to find the lowest point pointed by the pointer, which is the actual size of the inner hole. The outer diameter is the same.

[0025] Specifically, as Figure 1 shown, it is a portable inspection measuring tool. This measuring tool measures the workpiece through the comparison method. Therefore, before the detection, it is necessary to calibrate the dial indicator first through gauge blocks or sample rings. Only after the calibration can the measurement be carried out. When measuring, the dial scale can be directly observed to judge whether the machining size is qualified.

[0026] During implementation, the operation is carried out according to the following steps:

[0027] 1) First, press the sliding measuring frame 9 to apply force to the swinging block 13, and push the auxiliary rod 11 to move upward through the swinging block 13;

[0028] 2) Then drive the sliding rod 6 to move upward, so that the automatic switch 19 assembly on the sliding rod 6 approaches the center and enters the locking hole position of the auxiliary rod 11;

[0029] 3) Then adjust the gear bolt 16 and rotate it, thereby driving the threaded rod 17 to move, driving the swinging block 13 to move, and rotating the other gear bolt 16 in the reverse direction;

[0030] 4) Finally, release the auxiliary rod 11 by the automatic locking switch to complete the inner and outer diameter switching and measure the workpiece.

[0031] In summary, for the locking device of the grinding machine measuring system, press the sliding measuring frame 9 to apply pressure on the swing block 13 by the sliding measuring frame 9. Push the auxiliary rod 11 to move upward through the swing block 13, drive the sliding rod 6 to move right upward along the self-locking slideway 5, and make the automatic switch 19 on the sliding rod 6 gradually approach the center and finally fall into the locking hole position on the auxiliary rod 11. At this time, the auxiliary rod 11 is locked; then adjust the gear bolt 16, rotate the gear bolt 16 clockwise to the extreme position, drive the threaded rod 17 to move in the direction of the positioning shaft 15 by the threaded rod 17, and drive the swing block 13 to move at the same time. At this time, the swing block 13 will gradually move away from the auxiliary rod 11 until they are separated. Then adjust the other gear bolt 16 in the same way and also rotate it to the extreme position. The swing block 13 at the other end will just be directly below the auxiliary rod 11. At this time, press the automatic locking switch to release the auxiliary rod 11 to complete the inner and outer diameter switching and measure the workpiece, so as to achieve the purpose of facilitating the measurement of the workpiece and locking to improve stability.
