Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, specifically to an optical probe tripod testing fixture. Background Technology

[0002] In the field of optical probe tripod testing, specialized testing fixtures are needed to ensure the accuracy and stability of the installation, fixation, and measurement of optical probe tripods in order to meet the high precision requirements of optical measurement. However, existing testing fixtures still have room for improvement and optimization in terms of structural design, installation and fixation methods, measurement accuracy assurance, and versatility.

[0003] The shortcomings of existing technology:

[0004] 1. Insufficiently stable installation: Current testing fixtures are difficult to precisely match the shape and structure of the tripod when used with it, which cannot ensure the stability of the tripod after installation. This can easily lead to loosening or displacement during the testing process, thus affecting the accuracy of the measurement results.

[0005] 2. Measurement accuracy is difficult to guarantee: Optical measurement has extremely high accuracy requirements, but existing testing fixtures cannot well meet the needs of high-precision measurement in terms of their own flatness, parallelism, and the fixing and measurement methods of the conductive posts on the tripod, which easily introduces measurement errors.

[0006] 3. Inconvenient installation and adjustment of conductive posts: The existing installation methods for conductive posts on tripods are not flexible enough, making it difficult to quickly disassemble and accurately adjust them. This is not conducive to the maintenance and replacement of conductive posts and the optimization of measurement positions during the testing process.

[0007] Therefore, existing technologies have shortcomings and need further improvement. Utility Model Content

[0008] To address the problems existing in the prior art, this utility model provides an optical probe tripod testing fixture.

[0009] To achieve the above objectives, the specific solution of this utility model is as follows:

[0010] This utility model provides an optical probe tripod testing fixture, comprising:

[0011] A tripod bracket with conductive posts on it;

[0012] The testing fixture has a first hole and a countersunk hole respectively at the middle position of its upper and lower sides. The countersunk hole is connected to the first hole. The lower end of the triangular bracket is installed in the first hole by a bolt. The bolt shank is connected to the lower end of the triangular bracket by a thread. The head of the bolt is set in the countersunk hole.

[0013] The side wall of the triangular bracket is provided with three second holes evenly distributed around the circumference. A conductive post is detachably installed in each second hole. The height of the highest point on the upper side of the three conductive posts is measured using a height gauge to determine whether they are at the same height.

[0014] Furthermore, a mounting post is provided at the top of the triangular bracket, and a first through hole is provided at the center of the mounting post.

[0015] Furthermore, the lower end of the triangular bracket located in the first hole is also provided with an annular groove.

[0016] Furthermore, the detection fixture is disc-shaped.

[0017] Furthermore, the flatness and parallelism of the upper and lower end faces of the testing fixture are both within 0.002 mm;

[0018] The flatness of the upper contact surface of the triangular bracket is within 0.005mm.

[0019] Furthermore, the first hole on the upper side of the testing fixture matches the shape of the triangular bracket to ensure a stable fixation.

[0020] Furthermore, the three conductive posts are arranged in an equilateral triangle on the triangular support.

[0021] Furthermore, the testing fixture and the tripod are made of metal;

[0022] The bolt is made of alloy steel.

[0023] Furthermore, the triangular bracket is an equilateral triangle structure, with three conductive posts respectively located at the three vertices of the triangular bracket.

[0024] Furthermore, the second hole is a threaded hole.

[0025] The technical solution of this utility model has the following beneficial effects:

[0026] 1. Improved measurement accuracy: The flatness and parallelism of the upper and lower end faces of the testing fixture are controlled within a very small range, and the flatness of the upper contact surface of the tripod is also within 0.005mm. This high-precision design provides an accurate reference surface for the measurement of the optical probe tripod, effectively reducing the measurement error caused by the flatness and parallelism error of the fixture itself, and improving the accuracy of the measurement results.

[0027] 2. Ensure the installation is secure:

[0028] The first hole on the upper side of the testing fixture matches the shape of the tripod bracket, ensuring that the tripod bracket is securely installed on the testing fixture and avoiding the situation where the measurement results are affected by the tripod bracket loosening or displacement during the testing process.

[0029] The lower end of the triangular bracket is connected to the testing fixture by bolts. The bolt shank is threaded with the lower end of the triangular bracket, and the bolt head is located in the countersunk hole. This connection method not only provides sufficient installation strength, but also ensures the integrity and aesthetics after installation. At the same time, it is easy to disassemble and install, improving the ease of use of the testing fixture.

[0030] Easy adjustment and replacement of conductive posts: The three second holes on the side wall of the triangular bracket are threaded holes, and the conductive posts can be detachably installed in the second holes. This design makes the installation, adjustment and replacement of conductive posts very convenient. The position of the conductive posts can be flexibly adjusted or damaged conductive posts can be replaced according to actual testing needs, which extends the service life of the testing fixture and reduces the cost of use.
