Abstract
Description
Technical Field
[0001] This utility model relates to the field of planar polishing technology, and in particular to a pressure-applying mechanism for planar polishing of optical elements. Background Technology
[0002] In the manufacturing of precision optical components, grinding and polishing are often essential steps. During the polishing process, uniform pressure is required to ensure full contact between the component and the grinding wheel, achieving the best polishing effect. In practice, a pressure iron is often placed directly on the center of the component to apply downward pressure. However, when machining large components, it is often difficult to find a matching pressure iron. Therefore, multiple pressure irons are often required for machining large components, which can lead to uneven pressure and an uneven surface. Furthermore, during the reshaping and fine-tuning of the optical component's surface, it is often necessary to apply different pressures to the component using pressure irons to ensure inconsistent contact pressure between the surface and the grinding wheel, thus achieving the desired reshaping and fine-tuning effect. Utility Model Content
[0003] In view of the technical problems existing in the background art, the present invention aims to provide a planar polishing and pressurizing mechanism for optical elements. This device overcomes the defects of the prior art and can adapt to the needs of different sized elements and different counterweight pressures.
[0004] To solve the above problems, the technical solution of this utility model is as follows: A planar polishing and pressurizing mechanism for optical elements includes a chassis, a weight block A, a sliding groove, and a plug. Multiple sets of radial sliding grooves are evenly spaced along the circumferential direction on the top surface of the chassis. A positioning plate is fixedly installed at the upper part of each set of sliding grooves. Multiple sets of insertion holes A are evenly spaced along the radial direction on the positioning plate. One end of the weight block A is provided with a support rod, which is inserted into the sliding groove below the positioning plate through a clearance fit and can slide along the sliding groove. Multiple sets of insertion holes B corresponding to insertion holes A are evenly spaced along the longitudinal direction of the support rod. The plug passes through the insertion holes A of the positioning plate and is inserted into the insertion holes B of the support rod, thereby fixing the relative position of the weight block A and the chassis.
[0005] Preferably, it also includes a weight-adding block B, wherein the weight-adding block A has a slot at the middle of both sides of its top surface, and the cross-section of the slot is a trapezoidal structure that gradually decreases from top to bottom; and the weight-adding block B has an insert block at the middle of both sides that matches the slot.
[0006] The chassis and the bottom of the weight-adding block B are provided with a polyurethane protective layer.
[0007] The top surface of the chassis is provided with six sets of evenly spaced sliding grooves.
[0008] Both the chassis and the weight-adding block A are made of stainless steel.
[0009] The beneficial effects of this utility model are as follows: This invention, through a combination of multiple positioning plates, insertion holes, and bolts, allows for arbitrary adjustment of the distance between the weight-adding block A and the base, accommodating pressing parts of different lengths and sizes. Simultaneously, this pressurization method effectively solves the problems of uneven pressure and difficulty in adjustment, ensuring full contact between the workpiece and the grinding disc, thereby achieving the best polishing effect.
[0010] This utility model adds a slot, and the weight-adding block B can be fixed to the weight-adding block A through the slot to increase the counterweight, further increase the pressure, and at the same time ensure the uniformity of the pressure.
[0011] This invention avoids the problems of needing to select different weight-adding devices when polishing optical components of different sizes, and the need for multiple people to handle large weight-adding devices. It saves labor and processing costs, improves enterprise work efficiency, and has good application prospects. Attached Figure Description

[0015] Referring to the accompanying drawings, an optical element planar polishing and pressurizing mechanism in this embodiment includes a chassis 1, a weight block A3, a sliding groove 5, and a bolt 6. Multiple sets of radially spaced sliding grooves 5 are evenly arranged on the top surface of the chassis 1 along the circumferential direction. A positioning plate 7 is fixedly installed at the upper part of each set of sliding grooves 5. Multiple sets of insertion holes A10 are evenly arranged radially on the positioning plate 7. A support rod 8 is provided at one end of the weight block A3. The support rod 8 is inserted into the sliding groove 5 below the positioning plate 7 through a clearance fit and can slide along the sliding groove 5. Multiple sets of insertion holes B11 corresponding to the insertion holes A10 are evenly arranged longitudinally on the support rod 8. The bolt 6 passes through the insertion holes A10 of the positioning plate 7 and is inserted into the insertion holes B11 of the support rod 8, thereby fixing the relative position of the weight block A3 and the chassis 1.
[0016] It also includes a weight-adding block B2. The weight-adding block A3 has a slot 4 at the middle of both sides of its top surface. The cross-section of the slot 4 is a trapezoidal structure that gradually decreases from top to bottom. The weight-adding block B2 has an insert 9 at the middle of both sides that matches the slot 4.
[0017] The bottom surfaces of the chassis 1 and the weight-adding block B2 are provided with a polyurethane protective layer.
[0018] The top surface of the chassis 1 is provided with six sets of sliding grooves 5 at even intervals.
[0019] Both the chassis 1 and the weight-adding block A3 are made of stainless steel.
[0020] The working process of this embodiment is as follows: According to the requirements of the workpiece, after placing the weight block A3 at an appropriate position around the chassis 1, insert the pin 6 into the pin hole A under the positioning plate 7 through the pin hole B on the support plate 8 to fix the weight block A3 at an appropriate position around the chassis 1. According to the pressure requirements, insert the weight block B2 into the slot 4 of the weight block A3 through the insert block 9 in the middle of its side. After balancing the pressure at various points, place the workpiece under the chassis 1. The chassis 1 applies uniform pressure to the workpiece to make it fully contact the grinding disc, thereby achieving the best polishing effect.
