Full-size measuring devices are usually used in the field of precision engineering to measure the dimensions of large parts or assemblies. The pre-positioning component is a key part of this device. It is responsible for ensuring that the object to be measured can be correctly positioned on the measuring equipment for accurate measurement.

[0003] At present, when the pre-positioning component is used inside the measuring device, the flexibility of the positioning component is poor. In the process of measuring different positions of the workpiece, it is necessary to remove the positioning device and then move the workpiece, and then use the positioning device to position it, which is particularly troublesome.

A second motor 19 is arranged on the top inner wall of the measuring platform 1, and the output end of the second motor 19 is connected to the bottom end of the rotating frame 20. An electric push rod 14 is arranged on the bottom inner wall of the measuring platform 1. A telescopic rod 15 is arranged on the output end of the electric push rod 14. A bearing 16 is arranged on the outer side of the telescopic rod 15. A rising frame 17 is arranged on the top of the bearing 16. The top end of the rising frame 17 is connected to There is a top plate 18, and the top plate 18 is movably engaged with the rotating frame 20 for combination connection. The internal thread of the rotating frame 20 is penetrated with two groups of No. 2 threaded rods 22, and one end of the No. 2 threaded rod 22 is rotatably connected with an extrusion block 23. The top of the measuring platform 1 is symmetrically penetrated with two groups of arc grooves 4, and the top of the measuring platform 1 is provided with a circular groove 5, and the circular groove 5 is located outside the arc groove 4.

[0025] Furthermore, the annular groove 5 is movably combined and connected with the ball 21 movably embedded in the bottom of the rotating frame 20. The ball 21 is used to rotate inside the annular groove 5, and the ball 21 can assist the rotating frame 20 in adjusting the use angle. The two groups of arc grooves 4 are used to provide active rising space and angle adjustment space for the rising frame 17. The output end telescopic rod 15 of the electric push rod 14 is connected to the rising frame 17 by means of a bearing 16. The bearing 16 can be used to adjust the use angle of the rising frame 17. The extrusion block 23 is connected to the No. 2 threaded rod 22 by means of a bearing, so that the extrusion block 23 can be rotated to adjust the use angle.

[0026] Furthermore, by connecting the rotating frame 20 with the output end of the No. 2 motor 19, when the No. 2 motor 19 is running, the rotating frame 20 can be adjusted at the top of the measuring table 1 for use angle. Due to the angle restriction of the rising frame 17 by the two groups of arc grooves 4, the rotation angle of the rotating frame 20 needs to be less than 175 degrees. Through the operation of the electric push rod 14, the telescopic rod 15 can push the rising frame 17 to move up and down, so that the top plate 18 set at the top of the rising frame 17 protrudes a certain height from the inside of the rotating frame 20. The top plate 18 can assist the workpiece to be measured to rise inside the rotating frame 20. Then, a rotational force is applied to the two groups of No. 2 threaded rods 22, and the extrusion block 23 is used to clamp the workpiece to be measured. Similarly, when it is necessary to flip the measuring surface of the measured workpiece, the use height of the top plate 18 is adjusted by the electric push rod 14 and the No. 2 threaded rod 22 cooperates with each other, which is convenient for mechanical assistance to manually operate and flip the workpiece, effectively reducing labor intensity and effectively improving work efficiency.

The measuring component 13 is composed of a laser sensor, and the movement of the measuring component 13 can be used to perform full-size measurement of the workpiece after clamping.
