Description

Technical Field

[0001] The utility model relates to the technical field of optical elements, in particular to a tooling for turning the outer circle of an optical element. Background Technique

[0002] Generally, the distance from the optical axis of an off-axis circular reflective optical element to the axis of its mother mirror represents its off-axis amount. To ensure the accuracy of the off-axis reflection system, it is necessary to precisely control the off-axis amount of the off-axis optical element and control the deviation between the geometric axis and the optical axis of the circular optical element within a certain range, which is generally ensured through the turning outer circle process.

[0003] Generally, during turning the outer circle, a metal cylinder is bonded to the back of the off-axis mirror. The axis of the cylinder is adjusted to coincide with the optical axis of the off-axis optical element through a three-coordinate measuring device. Then, the outer circle of the metal cylinder is clamped by a four-jaw chuck, and the rotation of the chuck drives the workpiece to rotate. The off-axis optical element is ground to the required size by feeding a grinding wheel from the side, and its outer circle is ensured to be coaxial with the metal cylinder.

[0004] When using a four-jaw chuck to clamp an optical element through a metal cylinder, it is relatively convenient to adjust the metal cylinder to the center of rotation of the turntable by adjusting the front and rear positions of the four jaws. If the back of the reflector needs to be adjusted to be perpendicular to the axis of rotation of the turntable at the same time, it requires multiple repeated clamping and fine-tuning, which is time-consuming and laborious. Because this adjustment method does not separate the adjustment of concentricity and the adjustment of axis inclination, the two adjustments will be coupled and affect each other, resulting in low assembly and adjustment efficiency. Summary of the Utility Model

[0005] Therefore, the technical problem to be solved by the utility model is to overcome the problem in the prior art that when using the four jaws of a four-jaw chuck to adjust the position and axis inclination of a workpiece, there is a problem that the position and axis inclination of the workpiece will be coupled and affect each other during adjustment, requiring multiple repetitions, being time-consuming and laborious, and having low assembly and adjustment efficiency.

The tooling for turning the outer circle of the optical element of the present utility model can separately adjust the concentricity between the workpiece and the turntable and the pitch of the workpiece axis, effectively separating the concentricity adjustment and the axis inclination adjustment, reducing the coupling between the two, quickly adjusting the position and attitude of the workpiece, having a high clamping efficiency, and saving the process time.

[0011] In an embodiment of the present utility model, a circular groove II is provided at the upper end of the translational adjustment seat, and the circular groove II is located at the center position of the translational adjustment seat.

[0012] In an embodiment of the present utility model, four second threaded holes are provided on the side wall of the translational adjustment seat where the second circular groove is located. The second threaded holes communicate with the second circular groove. The first adjustment screw is arranged in the second threaded hole, and the first adjustment screw is in threaded connection with the second threaded hole. One end of the first adjustment screw penetrates through the second threaded hole.

[0013] In an embodiment of the present utility model, a second annular boss is provided on the outer circumference of the translational sleeve.

When using the four-jaw method for clamping, the center alignment adjustment and the axis inclination adjustment are seriously coupled, and high requirements are placed on the experience of the adjustment master. The adjustment takes dozens of minutes, while only more than 10 minutes are required after using the present invention. BRIEF DESCRIPTION OF THE DRAWINGS
