Description

Technical Field

[0001] This application relates to the field of roundness measurement equipment, and specifically to a cylindrical roundness detection tooling for infrared lenses. Background Technique

[0002] Cylindricity detection is to place the measured cylindrical workpiece along the vertical axis into several equally spaced cross-sections on a rotary table. The rotary table drives the workpiece to rotate together, and the probe measures each equally spaced cross-section one by one. Then, the cylindricity error of the measured cylindrical surface is obtained by using the error evaluation method specified in the national standard.

[0003] The cylindricity detection of infrared lenses is very important because cylindricity directly affects the optical performance of the lenses. If the cylindricity of the lens is unqualified, it will cause light to be distorted when propagating in the lens, resulting in unfocused focal points and affecting the clarity and accuracy of the infrared imaging system.

[0004] CN219455044U discloses a roundness meter, which includes a bottom plate. A workbench is arranged on the surface of the bottom plate. One side of the top of the bottom plate is vertically installed with a support block through bolts. The support block and the axis of the workbench are on the same horizontal line. A track is arranged on the top of the support block. The cross-section of the track is T-shaped. An adjustment block is slidably installed on the upper surface of the track. A threaded rod is screwed on the surface of the adjustment block. The threaded rod penetrates through the adjustment block. An adjustment block is slidably installed on the surface of the track near the workbench. One end of the threaded rod is installed on the adjustment block through a bearing, and the other end of the threaded rod is provided with a knob. The inner and outer rings of the bearing can be fixed respectively by an inclined rubber pressing plate, so as to realize the simultaneous measurement of the inner and outer rings and prevent data failure caused by the stacking of errors and ensure the measurement results. However, in order to ensure the stability during rotation, referring to its specification, the above patent document detects the roundness of each height of the workpiece by adjusting the height of the probe multiple times, which not only makes the operation more cumbersome and results in low detection efficiency, but also increases errors due to multiple manual adjustments.

[0005] Based on this, the technical problem to be solved in this case is: how to solve the problem that the existing roundness meter cannot quickly and accurately detect the roundness of infrared lenses. Utility Model Content

[0006] To solve the above technical problem, this application provides a cylindrical roundness detection tooling for infrared lenses. This tooling adjusts the height of the infrared lens through a lifting base, so that an external probe can detect the cylindrical roundness of each height of the infrared lens, without the need for manual adjustment of the infrared lens multiple times, thereby avoiding errors caused by manual adjustment and improving the detection efficiency.

[0007] The technical solution of this application is:

[0009] In the above-mentioned infrared lens cylindricity detection tooling, the self-centering mechanism comprises an inner disk and an outer disk; the outer disk is arranged on the rotating base; the inner disk is arranged on the outer disk and is provided with three swing arms. When the inner disk rotates, the swing arms move towards the center to adjust the infrared lens to be measured to the rotation axis of the rotating base.
