Embodiment 1

[0029] see figure 1 a, a ring polishing machine, including a turntable 1, a polishing disc 2, a limit roller mechanism 3 and a workpiece ring 4, the polishing disc 2 is also provided with a narrow groove, it is characterized in that the workpiece ring 4 The inner diameter is smaller than the width of the ring of the polishing disc 2, and the outer diameter is larger than the width of the ring of the polishing disc 2. The narrow groove divides the disc surface of the polishing disc into a plurality of small units, and the area variation trend of each small unit is along the direction of the polishing disc 2. The radius of becomes larger and then smaller from the center to the edge.

[0030] see figure 2 a and figure 2 b, figure 2 a and figure 2 b represents a groove shape, the narrow groove divides the surface of the polishing disc into multiple small units, and the area of ​​each small unit tends to change from small to large and then small along the radius of the poli...

Embodiment 2

[0032] see figure 1 b, a ring polishing machine, including a turntable 1, a polishing disc 2, a limit roller mechanism 3 and a workpiece ring 4, the polishing disc 2 is also provided with a narrow groove, it is characterized in that the workpiece ring 4 The inner diameter is smaller than the width of the ring of the polishing disc 2, and the outer diameter is larger than the width of the ring of the polishing disc 2. The narrow groove divides the disc surface of the polishing disc into a plurality of small units, and the area variation trend of each small unit is along the direction of the polishing disc 2. The radius of becomes smaller from the center to the edge.

[0033] see figure 2 c and figure 2 d, figure 2 c and figure 2 d represents a groove shape, the narrow groove divides the disc surface of the polishing disc into multiple small units, and the area of ​​each small unit tends to change along the radius of the polishing disc 2 from the center to the edge.

Embodiment 3

[0035] see figure 1 c, a ring polishing machine, including a turntable 1, a polishing disc 2, a limit roller mechanism 3 and a workpiece ring 4, the polishing disc 2 is also provided with a narrow groove, it is characterized in that the workpiece ring 4 The inner diameter is smaller than the width of the ring of the polishing disc 2, and the outer diameter is greater than the width of the ring of the polishing disc 2. The narrow groove divides the disc surface of the polishing disc into a plurality of small units, and the depth variation trend of the narrow groove is along the polishing disc 2. The radius changes from darker to lighter, then darker from the center to the edge.

[0036] see image 3 a, image 3 a is a schematic diagram of the groove depth, and the depth variation trend of the narrow groove is along the radius of the polishing disc 2 from the center to the edge from deep to shallow, and then to deep.

Abstract

A novel annular polisher comprises a turntable, a polishing disk, a limiting roller mechanism and a workpiece ring, wherein slotting or material flowing property of the polishing disk is specially designed. The invention solves the problem that a conventional annular polisher has to employ a large-sized correction plate. As the correction plate is omitted, the annular polisher is conductive to reducing the power of a polishing disk driving motor, lowering the equipment cost, improving the operational stability, reducing temperature rise of the surface of the polishing disk and improving the utilization ratio and the polishing efficiency of the surface of the polishing disk, and the service life of the polishing disk can be prolonged.

Description

technical field [0001] The invention relates to optical processing, in particular to a ring polishing machine. Background technique [0002] The ring polishing machine is a kind of high-precision optical element processing equipment. Due to the need to adjust the surface shape of the polishing disc, a large-sized calibration plate must be used, which will cause five hazards. First, the friction of the calibration plate on the disc surface is very large. , so a high-power motor must be used to drive the polishing disc, and special equipment must be used for the loading and unloading of the calibration plate, which increases the cost of the equipment, and the price of the large-size calibration plate itself is relatively high; the second is that the large-size calibration plate increases The labor intensity of the staff; the third is that most of the energy is used to polish the calibration plate instead of the workpiece when the equipment is running, which causes a waste of e...
