A cylinder 13 is arranged on one side of the main mounting plate 1, and a cylinder rod of the cylinder 13 is in contact and connected with a transverse slide 2 arranged on the end face through a floating joint 12. A laser ranging sensor B is arranged at the bottom of the transverse slide 2, one end of the Z-axis slide 5 is connected to a switch bracket 6, and a laser ranging sensor A7 is arranged on the switch bracket 6. A limiter is arranged on the back of the switch bracket 6, and the limiter moves in the long strip hole on the upper part of the transverse slide 2. Every two transverse slides 2 are connected by a connecting component.

[0028] The position-limiting member is an oil-free bushing, which is inserted through the long hole but does not contact the long hole. The oil-free bushing is connected to the switch bracket 6 and the Z-direction slide plate 5 by screws.

[0029] Preferably, two transverse slides 2 are provided.

[0030] The connecting assembly includes a swivel connecting plate 8, which is arranged on the main mounting plate 1. The two connecting holes of the swivel connecting plate 8 are respectively connected to the transverse slide 2 through joint connecting parts, one of the connecting holes is connected to the bottom of one of the transverse slides 2, and the other connecting hole is connected to the middle of the other transverse slide 2.

[0031] The joint connection comprises two joint bearings 10 , and the two joint bearings 10 are connected via a circular support 9 .

[0032] The cylinder 13 is arranged on the main mounting plate 1 through the cylinder connecting member 11 .

[0033] A blocking cylinder 16 and a proximity switch 15 are provided on the back of the main mounting plate 1 to detect and limit the position of the limiting member, and further limit the position of the laser ranging sensor A7 and the laser ranging sensor B.

[0034] The proximity switch 15 is arranged on the main mounting plate 1 through the proximity switch bracket 14 .

[0035] The rotary connecting plate 8 is connected to the main mounting plate 1 through bearings and cantilever pins.

[0036] Two transverse guide rails 3 are provided, and the two are arranged side by side, and are respectively arranged in the middle and lower part of the main mounting plate 1. Two Z-axis guide rails 4 are provided, and the Z-axis guide rails 4 are arranged obliquely. Preferably, the Z-axis guide rails 4 are obliquely installed on the inclined surface processed on the main mounting plate 1.

It is preferred that two sensor displacement mechanisms are arranged opposite to each other. After the two sensor displacement mechanisms reach the designated position, the cylinder 13 works according to the size of the end face of the crystal rod. The cylinder 13 pushes the transverse slide 2 on one side to move on the transverse guide rail 3, thereby driving the rotary connecting plate 8 and the joint bearing 10 to work, and further driving the other transverse slide 2 to move on the transverse guide rail 3, so as to achieve the purpose of adjusting the horizontal spacing of the two transverse slides 2. At the same time, during the transverse movement of the two transverse slides 2, the Z-direction slide 5 will be driven to move on the Z-axis guide rail 4. The movement of the Z-direction slide 5 on the Z-axis guide rail 4 can adjust the Z-axis spacing of the laser ranging sensor A 7. After the horizontal and vertical distances are adjusted, the measurement points of the four laser ranging sensors will point to the four corners of the measured crystal rod. According to the relevant data transmitted back, the orientation of the end face of the measured crystal rod is calculated using the four-point method, and the direction result is used to determine whether the next adjustment process is required.
