Description
Technical Field
The utility model relates to an optical manufacturing frock clamp, especially a vacuum adsorption anchor clamps for prism processing.
Background
The processing and production process of the prism is quite complex, dozens of processing procedures are needed from a blank to a polished blank, the traditional prism processing fixing mode is generally that the prism is clamped by a wax-bonded plate or a photoresist plate, the clamping and the unloading speed are slow in the two clamping modes, and the unloading process needs to use a large amount of toxic chemical reagents for soaking and cleaning, so that on one hand, the environment pollution is caused, and on the other hand, the harm is caused to human bodies. The surface of the product to be processed is very easily damaged in use by the traditional clamping and fixing mode, and the damage needs to be processed in the later period, so that the waste of manpower, material resources and financial resources is caused. In addition, the traditional clamping mode has low processing efficiency and needs repeated clamping and unclamping.
At present, chinese patent No. CN107443200B discloses a novel vacuum-adsorbable adjusting table for milling and grinding. From the angle of improving the positioning accuracy of the workpiece in the milling process, the vacuum adsorption adjusting table is designed, so that the angle fine adjustment of the element to be milled is realized on the premise of ensuring the vacuum adsorption force, and the radial accurate positioning of elements with different calibers can be ensured. The adjusting table can conveniently work on a milling and grinding machine, and replaces a general vacuum adsorption clamp; an adjustable and controllable angle adjustment freedom degree is added to the milling and grinding initial position of the workpiece, axial uneven deformation in the vacuum adsorption process (especially an O-shaped sealing ring) is compensated, the milling and grinding positioning precision is improved, and the milling and grinding precision is further ensured. The invention can realize high-precision repeated positioning of the optical element, is beneficial to exploring the influence rule of milling process parameters on the milling process, and has great advantages in milling application of the optical element with special requirements on indexes such as parallelism, concentricity, edge thickness difference and the like.
The fixture can realize high-precision repeated positioning of the optical element and can adjust the angle, but equipment is relatively complex, the number of adjusting modules is large, time is consumed in operation, and the machining accuracy of the workpiece with high precision requirement is difficult to guarantee due to the fact that the number of moving parts is large.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a vacuum adsorption anchor clamps of prism processing makes the simplification that the processing technology flow of prism can be very big not enough to prior art.
In order to achieve the above purpose, the technical scheme of the utility model is that:
the utility model provides a vacuum adsorption anchor clamps for prism processing which characterized in that includes: the inner part of the circular chassis base is a cavity and mainly used for providing a vacuum chamber; an air inlet and outlet valve controlled by a switch is arranged at the center of the bottom of the circular chassis base, when a workpiece to be processed is clamped, the air valve is opened for vacuumizing, and when the workpiece is unclamped, the valve is opened for air inlet; a sealing ring groove and fastening screw holes are formed in the side wall of the circular chassis base, the sealing ring groove is used for placing a sealing ring to ensure good air tightness, and the fastening screw holes are used for connecting and reinforcing the cover plate and the circular chassis base; be provided with seal ring groove, fastening screw hole and absorption hole on the apron, the absorption hole evenly distributed that sets up on the apron is on the apron, and link up apron upper and lower surface.
Furthermore, the outer diameters of the circular chassis base and the cover plate are consistent, and the shapes of the sealing ring grooves are mutually matched.
Furthermore, a sheet-shaped sealing ring is arranged at the adsorption hole on the cover plate.
The utility model has the advantages that:
the vacuum adsorption clamp provided by the utility model has the characteristics of simple structure, strong practicability, convenient manufacture, no need of gluing or wax gluing and high structural strength; compared with the traditional clamping and fixing mode, the workpiece can be quickly assembled and disassembled, so that the time and the cost are saved; after the prism workpiece is processed, the prism workpiece does not need to be soaked and cleaned by chemical reagents, so that the pollution of the chemical reagents to the environment and the harm to the bodies of operators are greatly reduced; the clamp and the workpiece to be machined are in soft contact, so that the workpiece cannot be damaged.
