Description

Technical Field

[0001] The utility model relates to the technical field of metal reflector processing, in particular to a mirror surface grinding device for a metal reflector. Background Art

[0002] Among metal reflectors, plane reflectors are more commonly used; the production process of metal plane reflectors is complicated. In order to ensure that the plane reflectors have good performance during use, the metal plane reflectors generally need to be rough-processed first and then fine-processed. In the rough processing, in the prior art, the staff takes the blank metal reflector and places it on the existing vise for clamping, and then uses the machine tool to use the grinding disc to cut and grind the large metal bumps on the mirror surface for the subsequent fine processing.

[0003] The utility model with the publication number CN213136098U proposes a mirror polishing machine tool for a metal reflector, including a carrier, a clamping mechanism for clamping the reflector and a mirror polishing mechanism used in conjunction with the clamping mechanism installed on the carrier; the clamping mechanism includes a clamping disc fixed on the carrier, a plurality of groups of clamping members arranged circumferentially on the clamping disc, and a driving member for controlling each group of clamping members to synchronously approach or synchronously move away from the axis of the clamping disc, wherein: each group of clamping members is two and centrally symmetrically distributed on the clamping disc; the mirror polishing mechanism includes a support frame fixed on the carrier, a grinding disc movably connected to the support frame, and a power member for driving the grinding disc to move toward or away from the clamping disc. The problem of low efficiency and low clamping precision of the existing manual clamping of the lens using a vise and a clamping chuck is solved, the purpose of fast clamping of lenses of different diameters is achieved, and the mirror rough processing efficiency of the metal reflector is improved.

[0004] However, the above-mentioned prior art still has some shortcomings when in use: 1. The supporting platform can only process one metal reflector at a time. After the processing of the current metal reflector is completed, loading and unloading operations need to be performed, and the loading and unloading operations will take a certain amount of time. For multiple workpieces that need to be polished, this operation will reduce the processing efficiency; 2. The grinding wheel can only move up and down. When the grinding wheel is polishing, the linear speed of its polishing working surface is in a state of gradually increasing along the radial outward square. As a result, the upper end surface of the metal reflector will be in a problem of uneven polishing force and speed. That is to say, the polished surface of the metal reflector becomes rougher as it approaches the middle, thereby affecting the polishing quality.

[0005] To this end, the utility model provides a mirror surface polishing device for a metal reflector. Utility Model Content

The upper end surface of the support truncated platform 2 is provided with a clamping portion 21 that is evenly distributed circumferentially relative to the support column 11. Each clamping portion 21 can hold a metal reflector blank, so that a plurality of metal reflector blanks evenly distributed circumferentially can be placed on a support truncated platform 2 at the same time. A telescopic drive member 8 is provided on the support column 11 and is located below the support truncated platform 2. The telescopic drive member 8 has the function of controlling the movement of a single clamping portion 21, that is, the function of the telescopic drive member 8 is to control a single clamping portion 21 to clamp the metal reflector blank thereon, so as to facilitate grinding and processing.

[0027] Specifically, the clamping portion 21 includes a limiting circular groove 211, two fixed piles 212, a movable pile 213 and a reset spring 214. The limiting circular groove 211 is provided on the upper disk surface of the grinding disk 41. The limiting circular groove 211 is a sink structure. The bottoms of the two fixed piles 212 are welded to the bottom inside the limiting circular groove 211. The bottom of a movable pile 213 is slidably connected to the bottom inside the limiting circular groove 211. The two fixed piles 212 and the movable pile 213 constitute the three corner points of a triangle. Preferably, the triangle is an isosceles triangle, wherein the movable pile 213 is the angle point of the two waist sides on the isosceles triangle. At this time, the movable pile 213 and the two fixed piles 212 are clamping blocks for tightening the outer periphery of the metal reflector blank, and the clamping and release can be controlled by sliding the movable pile 213.
