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

[0002] Optical component processing fixtures are mainly used to fix and protect optical components such as lenses, mirrors, prisms, etc. during the manufacturing process. These fixtures usually need to precisely control the position and direction of the optical components to ensure their stability and accuracy during the processing. In certain processing steps, such as grinding and polishing, optical components may be damaged. The use of fixtures can prevent these operations from causing unnecessary damage to the optical components.

[0003] However, the above device still has the following problems during implementation:

[0004] Existing technologies, such as grinding and polishing, may cause damage to optical elements. A fixture can prevent the optical elements from moving, but existing fixtures are clamped by two left and right clamps. During the processing, if the fixture cannot firmly fix the optical element, the optical element may move or deform during the processing, which will also affect the processing accuracy. Therefore, a fixture for optical element processing is specially proposed to solve the above problems. Utility Model Content

[0007] Three clamping assemblies for clamping the optical element, the clamping assemblies are arranged on the top of the platform connecting member, the clamping assemblies include a clamping member, the clamping member is movably connected to the top of the platform connecting member, a side of the clamping member close to the movable hole is rotatably connected to an extrusion plate through a rotating shaft, and a side of the clamping member away from the movable hole is fixedly connected to a rubber member;

[0008] A control component for controlling three clamping components, wherein the control component is arranged in the inner cavity of the mounting groove.

[0009] As a preferred embodiment of the utility model, the clamping member is fixedly connected to a travel block on the side away from the extrusion plate, the surface of the travel block is movably connected to a U-shaped plate, the bottom of the U-shaped plate is fixedly connected to the top of the platform connecting member, and by arranging the travel block and the U-shaped plate, the travel block and the U-shaped plate can control the moving position of the clamping member when the clamping member moves, so that the clamping member will not warp up when the extrusion plate squeezes the clamping member.

By setting up the control component, when it is necessary to control three rotating members at the same time, the rotation of the screw will drive the lifting member to descend, because the matching plate is rotatably connected to the lifting member through a rotating shaft, and at this time the three matching plates can squeeze the three rotating members to rotate.

[0011] As a preferred embodiment of the utility model, the outer surface triangles of the lifting member are rotatably connected to the matching plate via a rotating shaft, the side of the matching plate away from the lifting member is rotatably connected to the rotating member via the rotating shaft, the side of the rotating member close to the extrusion plate is rotatably connected to the extrusion plate via the rotating shaft, and the side of the rotating member close to the inner wall of the movable hole is rotatably connected to the inner wall of the movable hole via the rotating shaft.

[0012] As a preferred embodiment of the present invention, the triangles on the top of the lifting member are provided with control holes, the inner cavity of the control hole is plugged with a control rod, the top of the control rod is rotatably connected to the inner wall of the mounting groove, and by providing the control hole and the control rod, when the lifting member moves up and down in the mounting groove, the control hole and the control rod can control the moving position of the lifting member, so that the lifting member will not rotate when being pulled by the screw rod.

[0013] As a preferred embodiment of the utility model, the surface of the screw is fixedly connected with a bevel gear ring, and the bottom of the bevel gear ring is meshingly connected with conical teeth. By arranging the bevel gear ring and the conical teeth, when it is necessary to conveniently control the rotation of the screw, the rotation of the conical teeth will drive the meshing bevel gear ring to rotate, and the rotation of the bevel gear ring extrusion drives the screw to rotate.

By arranging the rotating rod and the holding piece, when it is necessary to control the rotation of the conical tooth, the holding piece can be held to drive the rotating rod to rotate, and the rotation of the rotating rod can drive the conical tooth to drive the conical tooth ring to rotate.

[0015] The utility model arranges the coordinated use of the clamping assembly, the clamping piece, the extrusion plate, the rubber piece and the control assembly. When the lifting piece descends, it drives the matching plate to extrude the rotating piece. When the rotating piece rotates, the extrusion plate extrudes the clamping piece to move. The movement of the clamping piece drives the rubber piece to clamp the optical element. At this time, the rotating holding piece can be stopped, thereby solving the problem that the clamp is clamped by the left and right clamping plates. During the processing, if the clamp cannot firmly fix the optical element, the optical element may move or deform during the processing, which also affects the processing accuracy.

[0023] like Figures 1 to 4 As shown, an optical element processing fixture provided by an embodiment of the utility model comprises a platform connecting member 1, a mounting groove 2 and three movable holes 3, wherein the mounting groove 2 is provided in the inner cavity of the platform connecting member (1), and the movable holes 3 are provided at the top of the mounting groove 2;

[0027] The above solution is adopted: by setting the travel block 6 and the U-shaped plate 7, when the clamping member 41 moves, the travel block 6 and the U-shaped plate 7 can control the moving position of the clamping member 41, so that when the extrusion plate 42 squeezes the clamping member 41, the clamping member 41 will not be lifted.

[0028] refer to Figure 3 The control component 5 includes a screw 51, the bottom of which is rotatably connected to the inner wall of the mounting groove 2 through a bearing seat, and the inner cavity of the mounting groove 2 is movably connected with a lifting member 52, and the top of the lifting member 52 is provided with a screw hole 53 used in conjunction with the screw 51, and the screw 51 is threadedly connected to the inner cavity of the screw hole 53.

[0029] Adopt the above scheme: by setting the control component 5, when it is necessary to control the three rotating parts 9 at the same time, the rotation of the screw 51 will drive the lifting part 52 to descend, because the matching plate 8 is rotatably connected with the lifting part 52 through the rotating shaft, and then the three matching plates 8 can squeeze the three rotating parts 9 to rotate.

[0030] refer to Figure 3 The triangles on the outer surface of the lifting member 52 are rotatably connected to the matching plate 8 through a rotating shaft. The side of the matching plate 8 away from the lifting member 52 is rotatably connected to the rotating member 9 through a rotating shaft. The side of the rotating member 9 close to the extrusion plate 42 is rotatably connected to the extrusion plate 42 through a rotating shaft. The side of the rotating member 9 close to the inner wall of the movable hole 3 is rotatably connected to the inner wall of the movable hole 3 through a rotating shaft.

[0031] The above solution is adopted: by setting the matching plates 8 and the rotating parts 9, when the three matching plates 8 are squeezed, the matching plates 8 will squeeze the three rotating parts 9 to move around the rotating axis, and at this time the rotating parts 9 squeeze the three squeezing plates 42.

[0035] The above solution is adopted: by setting the bevel gear ring 12 and the bevel teeth 13, when it is necessary to conveniently control the rotation of the screw 51, the rotation of the bevel teeth 13 will drive the meshing bevel gear ring 12 to rotate, and the rotation of the bevel gear ring 12 will drive the screw 51 to rotate.

[0036] refer to Figure 2 The rear side of the conical tooth 13 is fixedly connected with a rotating rod 14 , and the rear side of the rotating rod 14 passes through the mounting groove 2 and is fixedly connected with a holding piece 15 .

[0037] By adopting the above solution, by setting the rotating rod 14 and the holding member 15, when it is necessary to control the rotation of the conical teeth 13, holding the holding member 15 can drive the rotating rod 14 to rotate, and the rotation of the rotating rod 14 can drive the conical teeth 13 and the conical gear ring 12 to rotate.

[0038] During use, when the optical element needs to be clamped, the optical element is placed on the top of the platform connector 1, and then the holding member 15 is rotated to drive the rotating rod 14 to rotate. The rotation of the rotating rod 14 will drive the conical teeth 13 to rotate. The rotation of the conical teeth 13 will drive the top meshing conical gear ring 12 to rotate. The rotation of the conical gear ring 12 will drive the screw 51 to rotate around the bearing seat. The rotation of the screw 51 will drive the threaded lifting member 52 to descend. The descent of the lifting member 52 will drive the matching plate 8 to squeeze the rotating member 9. The rotation of the rotating member 9 will squeeze the plate 42 to squeeze the clamping member 41 to move. The movement of the clamping member 41 will drive the rubber member 43 to clamp the optical element. At this time, the holding member 15 can be stopped from rotating.

[0039] In summary: the optical element processing fixture, through the setting of the clamping assembly 4, the clamping part 41, the extrusion plate 42, the rubber part 43 and the control assembly 5, the lowering of the lifting part 52 will drive the matching plate 8 to extrude the rotating part 9, the rotation of the rotating part 9 will cause the extrusion plate 42 to extrude the clamping part 41 to move, the movement of the clamping part 41 will drive the rubber part 43 to clamp the optical element, and then the rotation of the holding part 15 can be stopped, which solves the problem that the fixture is clamped by the left and right clamps. During the processing, if the fixture cannot firmly fix the optical element, it may cause the optical element to move or deform during the processing, which will also affect the processing accuracy.
