Description

Technical Field

[0001] This utility model relates to the technical field of clamping devices, and specifically to a clamping device for precision polishing of irregularly shaped prisms. Background Technology

[0002] Irregular prisms refer to irregular prism bodies. In the process of processing irregular prisms, the surface of the irregular prism needs to be finely polished. In order to prevent the prism from moving during the fine polishing process, the prism needs to be limited, which requires the use of a limiting clamping device for auxiliary operation.

[0003] Existing clamping devices typically use an upper and lower pressing method for fixation. This involves a pressure plate that can slide on a slide bar, moving up and down to assist in fixation. The pressure plate and slide bar are pressed and fixed by a threaded compression rod. The compression is often carried out by one side, which makes the fixation effective but prone to loosening. At the same time, the length of the pressure plate is fixed, and the fixation effect will be reduced when it is necessary to fix prisms of different sizes.

[0004] To address the aforementioned issues, this application proposes a precision polishing and clamping device for irregularly shaped prisms. Utility Model Content

[0005] This utility model addresses the technical problems existing in the prior art by providing a precision polishing and clamping device for irregularly shaped prisms.

The top and bottom of the operating plate are provided with adjustment and limiting structures, and both sides of the operating plate are provided with auxiliary limiting structures. The adjustment and limiting structure includes a sliding rod. The top end of the sliding rod is fixedly connected to the bottom of the operating plate, and the bottom end of the sliding rod is slidably connected to a fixed cylinder. The bottom of the outer surface of the fixed cylinder is fixedly connected to a supporting circular plate. The auxiliary limiting structure includes a connecting plate. The inner wall of the connecting plate is threadedly connected to a threaded rod, and one end of the threaded rod is fixedly connected to a rubber circular block.

[0007] Preferably, a fixing rod is fixedly connected to the top of the outer surface of the operating plate, and a sliding ring is sleeved on the outer surface of the fixing rod. The inner walls of both sides of the sliding ring are threaded with first threaded clamps.

[0008] By setting a sliding ring, the height can be adjusted in conjunction with the fixing rod, and it can be fixed by the action of the first threaded clamp.

[0009] Preferably, an adjusting rod is fixedly connected to the outer surface of the sliding ring, one end of the adjusting rod is slidably connected to a trapezoidal pressure block, and a rectangular protrusion is fixedly connected to the bottom of the trapezoidal pressure block.

[0010] By setting an adjusting rod and a trapezoidal pressure block, the fixed position of the trapezoidal pressure block can be adjusted, and then auxiliary adjustments can be made according to the actual size of the prism.

[0011] Preferably, the top of the outer surface of the adjusting rod is provided with a threaded locking hole, and the inner wall of the trapezoidal pressure block is threadedly connected to a second threaded locking rod, which is threadedly connected to the inner wall of the threaded locking hole.

[0012] By setting a second threaded clamp and a threaded clamp hole, the trapezoidal pressure block and the adjusting rod can be auxiliaryly fixed.

[0013] Preferably, rectangular slots are provided on both inner walls of the operation panel, and rectangular blocks are engaged with the inner walls of the rectangular slots. A first screw hole is provided on the inner wall of the operation panel, and a second screw hole is provided on the bottom inner wall of the rectangular blocks. A third threaded rod is threadedly connected to the inner walls of the first and second screw holes.

[0014] By setting rectangular blocks and rectangular slots, auxiliary connecting plates and other components can be disassembled and assembled, and can be disassembled and assembled according to actual needs.

[0015] Preferably, an auxiliary connecting plate is fixedly connected to one side of the outer surface of the rectangular card block, the top of the outer surface of the auxiliary connecting plate is fixedly connected to the bottom of the outer surface of the connecting plate, and an operating block is fixedly connected to the end of the outer surface of the threaded rod away from the rubber block.

[0016] By setting rubber blocks, they can be used in conjunction with threaded rods and other components for auxiliary positioning, thereby helping to fix the prism.

[0017] The beneficial effects of this utility model are:

[0018] By setting an adjustable limit structure, the height of the operating plate can be adjusted with the help of the sliding rod and the fixed cylinder. At the same time, the height of the trapezoidal pressure plate can be adjusted with the help of the sliding ring under the action of the fixed rod. Thus, the height of the trapezoidal pressure plate can be adjusted according to the actual fixing requirements, thereby making the fixing more stable.

[0019] By setting an auxiliary limiting structure, the connecting plate can be assisted in disassembly and assembly under the action of rectangular blocks and rectangular slots. Furthermore, under the action of the threaded rod, the rubber round block can assist in fixing and clamping the prism, thereby enabling the prism to be more stably clamped and limited during the fine polishing process.

[0038] Working principle:

[0039] The user places the prism on the operation panel 1. At this time, the sliding ring 26 is adjusted so that it slides on the outer surface of the fixing rod 25. Then, the first threaded clamp rod 27 can be rotated to assist in fixing the sliding ring 26. At this time, the trapezoidal pressure block 29 can press the prism. When it is necessary to fix prisms of different sizes, the trapezoidal pressure block 29 is pulled so that it slides on the outer surface of the adjusting rod 28. The distance of the trapezoidal pressure block 29 can be adjusted. At this time, the second threaded clamp rod 211 is rotated so that it is fixed with the threaded clamp hole 210.
