Description

Technical Field

[0001] This utility model relates to the field of fixture technology, and to a fixture for grinding irregularly shaped prisms. Background Technology

[0002] A prism is a transparent object formed by two intersecting but non-parallel planes, used to split light or cause dispersion of light beams. Prisms are polyhedrons made of transparent materials (such as glass and crystal). They are widely used in optical instruments.

[0003] Prisms typically require grinding equipment for auxiliary grinding during production. To prevent the prism from shifting during grinding, a fixture is usually used. However, when clamping irregularly shaped parts, the fixture can only clamp fixed points or surfaces and cannot fully adapt to the outer surface of the irregularly shaped prism, resulting in unstable clamping. At the same time, during the grinding process, debris will splash into the operator's eyes, thus affecting the operator's operation.

[0004] To address the aforementioned issues, this application proposes a fixture for grinding irregularly shaped prisms. Utility Model Content

[0005] This utility model addresses the technical problems existing in the prior art by providing a fixture for grinding irregularly shaped prisms.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A fixture for grinding irregular prisms includes a base, with disassembly and assembly protective structures on both sides of the base and a fitting clamping structure on the top of the base. The disassembly and assembly protective structure includes a rectangular clamping plate, with a rectangular clamping frame clamped to the outer surface of the rectangular clamping plate. A U-shaped plate is fixedly connected to one side of the outer surface of the rectangular clamping frame. The fitting clamping structure includes a clamping frame, with a fixing rod fixedly connected to the inner wall of the clamping frame. A sliding cylinder is slidably connected to the outer surface of the fixing rod, and the sliding cylinder is slidably disposed on the inner wall of the clamping frame.

[0007] Preferably, the inner wall of the rectangular card plate is provided with a first screw hole, and the inner wall of the rectangular card frame is provided with a second screw hole, and the inner walls of the first screw hole and the second screw hole are threadedly connected to a threaded card rod.

[0008] By setting the first screw hole and the second screw hole, a threaded clamp rod can be used for assistance, thereby fixing the rectangular clamp plate and the rectangular clamp frame.

[0009] Preferably, an auxiliary rotating rod is rotatably connected between the two sides of the inner wall of the U-shaped plate, a rotating block is fixedly connected to the outer surface of the auxiliary rotating rod, and an L-shaped protective plate is fixedly connected to the outer surface of the rotating block. The L-shaped protective plate is made of transparent material.

[0010] By setting up an L-shaped guard plate, auxiliary protection can be provided during the grinding process to prevent debris from splashing into the eyes, thus making the operation more convenient for the operator.

[0011] Preferably, one end of the auxiliary rotating rod passes through the U-shaped plate and is fixedly connected to an operating round block. A locking rod is inserted into the inner wall of the operating round block, and several locking holes are opened on one side of the inner wall of the U-shaped plate.

[0012] By setting a locking rod and locking holes, the operating block can be assisted in being fixed, which in turn can be assisted in being fixed in the rotating block and the auxiliary rotating rod.

[0013] Preferably, a clamping block is fixedly connected to one end of the outer surface of the sliding cylinder, and a return spring is sleeved on the outer surface of the fixing rod. The two ends of the return spring are fixedly connected to the outer surface of the sliding cylinder and the inner wall of the clamping frame, respectively.

[0014] By setting a return spring, the sliding cylinder can slide on the fixed rod, causing the return spring to deform, and thus it can be reset under the force exerted by the spring.

[0015] Preferably, L-shaped plates are fixedly connected to both sides of the outer surface of the base, and a hydraulic telescopic rod is fixedly installed on one side of the outer surface of the L-shaped plate. The output end of the hydraulic telescopic rod is fixedly connected to one side of the outer surface of the clamping frame.

[0016] By setting up a hydraulic telescopic rod, the hydraulic telescopic rod can drive the clamping frame to move, which can then work with clamping blocks and other components to assist in clamping.

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

[0018] By setting up a disassembly and assembly protective structure, the L-shaped guard plate can be rotated to a suitable position under the action of the rotating block and the auxiliary rotating rod. It can then be fixed with the cooperation of the locking rod and the locking hole, thus preventing splashing and mainly avoiding debris from splashing into the operator's eyes. At the same time, with the cooperation of the rectangular locking plate and the rectangular locking frame, the L-shaped guard plate can be disassembled and assembled, and can be disassembled and assembled according to actual usage needs.

[0019] By setting up a fitting clamping structure, the clamping frame can be moved under the action of the hydraulic telescopic rod, which in turn can cause the clamping block and the sliding cylinder to slide on the outer surface of the fixed rod, so as to fit and fix them according to the appearance of the irregular prism, thus making the fixation more stable.

[0037] Working principle:

[0038] The user places the irregular prism on the base 1. At this time, the hydraulic telescopic rod 32 is activated, which allows the clamping frame 33 to move, thereby allowing the clamping block 36 to fit against the irregular prism. Then, according to the appearance of the irregular prism, the sliding cylinder 35 can slide on the outer surface of the fixed rod 34. Then, under the reaction force of the return spring 37, it can be assisted in limiting the position. At this time, the rectangular clamping frame 23 is engaged with the rectangular clamping plate 21, and the threaded clamping rod 25 is fixed with the first screw hole 22 and the second screw hole 24. Then, the L-shaped guard plate 29 is rotated, which causes the auxiliary rotating rod 27 and the rotating block 28 to rotate. After rotating to the appropriate position, the clamping rod 211 is engaged with the clamping hole 212 and fixed.
