Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

The specific implementation mode is as follows: referring to fig. 1-3, a high-precision centering instrument includes a host, a laser emitting disc, a receiving target disc, and two V-shaped supports 1, where a sliding rod 11 is disposed on the upper portion of each V-shaped support 1, an inverted V-shaped notch is disposed on the lower portion of each V-shaped support 1, the laser emitting disc and the receiving target disc are slidably connected to one V-shaped support 1, rails 12 are disposed on two sides of each V-shaped support 1, a moving clamping seat 2 is slidably connected to each rail 12 at one end, that is, two moving clamping seats 2 are provided, the moving clamping seat 2 can slide along the rail 12 and cannot fall off before reaching the end of the rail 12, a moving hanging seat 3 is slidably connected to the rail 12 at the other end, an upright column 31 is disposed at the outer end of the upper portion of the moving hanging seat 3, that is far away from the end of the sliding rod 11, the upright column 31 can hang a chain 54, a clamping groove 21 is disposed on the moving clamping seat 2, and the cross section of the lower portion of the clamping groove 21 is semicircular.

The device further comprises a fastening device 5, wherein the fastening device 5 comprises a bearing part 51, rotating shafts 511 are arranged on two sides of the bearing part 51, a threaded hole penetrating through the upper side and the lower side of the bearing part 51 is formed in the center of the bearing part 51, a bolt 52 is in threaded connection with the threaded hole, a traction part 53 is rotatably connected to the lower end of the bolt 52, and a chain 54 is connected to the lower end of the traction part 53.
