Description

Technical Field

[0001] The utility model relates to the technical field of positioning fixtures, in particular to a positioning fixture of an optical glass polishing machine which is anti-clamping damage. Background Art

[0002] The positioning fixture of the optical glass polishing machine is a device used to fix and position optical glass parts to ensure the accurate position and stability of the parts during the polishing process.

[0003] Publication number CN216883142U discloses a positioning fixture for an optical glass polishing machine, which relates to the field of optical glass processing technology; it includes: a horizontal positioning plate and a vertical positioning plate, both of which are fixedly connected to the upper surface of the base; an adjustment screw hole and a measuring hole are opened on the end face of the telescopic rod; one end of the connecting rod is fixedly connected to the back of the clamping block, and the other end of the connecting rod is fixedly connected to the front of the limit block, the connecting rod passes through the ring opening of the adjustment ring and is rotatably connected, one end of the adjustment screw is fixedly connected to the back of the limit block, the other end of the locking nut enters the adjustment screw hole and is screwed together, one end of the measuring plate is fixedly connected to the adjustment ring, and the other end of the measuring plate is slidably connected to the measuring hole. The advantage of this utility model is that the special-shaped optical glass is first placed against the horizontal positioning plate and the vertical positioning plate, and then the push-pull quick clamp is operated. The telescopic rod of the push-pull quick clamp drives the clamping block to move forward, and the clamping block cooperates with the horizontal positioning plate to conveniently clamp the optical glass. Although this type of optical glass positioning fixture is effective in fixing the glass, it is lacking in preventing pinching damage. Since this type of positioning fixture does not have a structure to protect the glass, the edges of the glass will be squeezed and broken when polished, thereby reducing the polishing yield of the optical glass.
