Description

Technical Field

[0001] This utility model relates to the field of shaft structure measuring fixtures, specifically to a de-rotating shaft structure measuring fixture. Background Technology

[0002] The despin axis mainly serves to despin and stabilize the aim. When the carrier (such as a tank, armored vehicle, or ship) bumps or sways during movement, the despin axis counteracts this carrier movement by moving in the opposite direction, keeping the upper optical equipment in a stable state pointing towards the target, thus achieving the functions of despin and stabilization. It also supports the weight of the entire upper mechanism (including the pitch axis, optical equipment, etc.) and drives it to rotate in azimuth (i.e., left and right).

[0003] Currently, after the anti-rotation shaft parts are machined, their dimensional accuracy needs to be measured using a projector. However, the projection measurement method is difficult and the measurement data error is not low, which makes it impossible to complete the dimensional accuracy measurement of the anti-rotation shaft accurately and efficiently. Therefore, this utility model proposes a measuring fixture for the anti-rotation shaft structure. Utility Model Content

[0004] To overcome the shortcomings of the prior art, this utility model provides a measuring fixture for a de-rotating shaft structure. Through the close cooperation between the measuring fixture and the de-rotating shaft structure, the accuracy of the de-rotating shaft structure can be quickly detected. The detection accuracy is good, the operation is simple and convenient, and the detection efficiency is significantly improved.

[0005] Technical solution

[0006] A measuring fixture for a de-rotating shaft structure includes a base plate. The upper surface of the base plate is provided with a mating groove for placing the de-rotating shaft structure. Several mating parts for detecting annular holes on the de-rotating shaft structure are arranged in a ring array within the mating groove. A rod part for detecting the central hole of the de-rotating shaft structure is also provided in the middle of the mating groove.

[0007] Furthermore, the bottom of the mating groove has a through-hole in a ring array, and the mating part is installed in the through-hole.

[0008] Furthermore, a mounting hole is provided through the center of the bottom of the mating groove, and the insert rod is inserted into the mounting hole.

[0009] Furthermore, two fine grooves are also formed on the base plate.

[0010] Furthermore, the groove is provided with a thin rod that can be inserted into the fine hole on the anti-rotation shaft structure.

[0011] Furthermore, the thin rod detects the included angle formed by the two thin holes.

[0012] Beneficial effects

[0013] Compared with the prior art, this utility model has the following advantages:

[0014] By closely matching the measuring fixture with the anti-rotation shaft structure, the accuracy of the anti-rotation shaft structure can be quickly tested. The test accuracy is good, the operation is simple and convenient, and the test efficiency is significantly improved. Attached Figure Description

[0022] To better illustrate the content of this utility model, the following description is provided in conjunction with the accompanying drawings and embodiments:

[0023] have Figures 1-5 As shown, this utility model discloses a measuring fixture for a de-rotating shaft structure, including a base plate 1. The upper surface of the base plate 1 is provided with a mating groove 2 for placing a de-rotating shaft structure 9. The mating groove 2 is provided with a plurality of mating parts 4 arranged in a ring array for detecting the annular holes 11 on the de-rotating shaft structure 9. The middle part of the mating groove 2 is also provided with an insertion rod part 5 for detecting the central hole 10 of the de-rotating shaft structure 9.

[0024] Furthermore, the bottom of the mating groove 2 is arranged in a ring array with through-holes 3, and the mating part 4 is installed in the through-holes 3.

[0025] Furthermore, a mounting hole 8 is provided through the center of the bottom of the mating groove 2, and the insertion rod 5 is inserted into the mounting hole 8.

[0026] Furthermore, two fine grooves 6 are also provided on the base plate 1.

[0027] Furthermore, a thin rod 7 capable of being inserted into the fine hole 12 on the anti-rotation shaft structure 9 is provided in the fine groove 6.

[0028] Furthermore, the thin rod 7 detects the included angle formed by the two thin holes 12.

[0029] Specifically, during use, first insert the rod part 5 into the mounting hole 8, then place the anti-rotation shaft structure 9 inside the mating groove 2, and check the bottom outer circle dimension of the anti-rotation shaft structure 9;
