[0001] The utility model relates to the technical field of optical glass processing, in particular to a clamp for heating optical glass. Background Art

[0002] Optical glass can be used to manufacture lenses, prisms, reflectors, and windows in optical instruments. Components made of optical glass are key components in optical instruments. During the processing of optical glass, it needs to be clamped and fixed before being heated. While existing optical glass heating fixtures can generally meet daily usage needs, there are still some shortcomings that need improvement.

[0003] Most of the optical glass heating clamps widely used on the market adopt split clamping to clamp and fix the optical glass from the upper and lower sides. However, in actual use, since the bottom of the upper clamp is located at the bottom, once debris adheres to the bottom of the upper clamp, it is easy to contaminate the optical glass if it is not cleaned in time. The bottom of the upper clamp needs to be observed frequently, which is inconvenient during use. Therefore, we propose an optical glass heating clamp to solve the above problem.

[0023] By installing a mounting seat 9 that can move back and forth at the side end of the operating table 1, and installing a detachable movable plate 10 in the mounting seat 9, when the bottom end of the upper splint 3 needs to be cleaned, the driving motor 21 can be driven to rotate the threaded rod 5, and the threaded sleeve 6 can drive the guide slider 8 and the mounting seat 9 to move laterally along the guide groove 7 under the action of the thread, so that the movable plate 10 can be driven by the mounting seat 9 to move to the bottom end of the upper splint 3, and the bottom end of the upper splint 3 can be quickly cleaned. There is no need to manually clean the bottom end of the upper splint 3, which prevents debris from adhering to the bottom end of the upper splint 3, thereby improving the convenience of using the device.

[0024] In other embodiments, the positioning assembly includes a mounting groove 12, a mounting block 13, a sleeve 14, a movable guide block 15, a positioning rod 16, a positioning hole 17, a connecting rod 18, a handle 19, and a return spring 20. The mounting seat 9 is provided with a mounting groove 12, the end of the movable plate 10 is fixed with a mounting block 13, the top of the mounting seat 9 is fixed with a sleeve 14, a movable guide block 15 is provided in the sleeve 14, and two groups of positioning rods 16 are installed at the bottom end of the movable guide block 15. Two groups of positioning holes 17 are provided on the mounting block 13, and the bottom ends of the two groups of positioning rods 16 can pass through the two groups of positioning holes 17 on the mounting block 13. The top of the movable guide block 15 is connected to the handle 19 through the connecting rod 18, and the outside of the connecting rod 18 is wrapped with a return spring 20;

[0025] When the cleaning sleeve 11 needs to be cleaned and replaced, the handle 19 can be pulled upward to allow the movable guide block 15 to drive the two sets of positioning rods 16 to move upward along the sleeve 14.

[0032] In other embodiments, the outer portion of the movable guide block 15 is fully fitted with the inner wall of the sleeve 14 , and the movable guide block 15 is in sliding connection with the inner wall of the sleeve 14 ;

[0033] With this design, when the movable guide block 15 slides up and down in the sleeve 14 , it can effectively prevent the movable guide block 15 from shaking during the movement, thereby improving the stability of the movable guide block 15 during movement.

[0034] In other embodiments, the handle 19 is provided with anti-slip textures on the outside;

[0035] This design can increase the friction between the handle 19 and the user's hand, making it easier to pull the handle 19.
