Description

Technical Field

[0001] This utility model relates to the field of cylindrical mirror polishing technology, specifically to a polishing device for a miniature cylindrical mirror. Background Technology

[0002] Cylindrical lenses are aspherical lenses that can effectively reduce spherical aberration and chromatic aberration. They are classified into plano-convex cylindrical lenses, plano-concave cylindrical lenses, biconvex cylindrical lenses, biconcave cylindrical lenses, meniscus cylindrical lenses, intergrowth cylindrical lenses, and irregular cylindrical lenses. They have one-dimensional magnification capabilities. During the processing of cylindrical lens substrates, polishing equipment is required. A search revealed existing technology (publication number: CN212399078U), which describes "a polishing device for cylindrical mirror substrates, comprising a bottom support, a lifting push rod, and a pressure transmitter. Guide columns are interference-fitted to both sides of the top of the bottom support. A lifting support plate is provided in the middle of the guide column. A guide sleeve is interference-fitted to the joint between the lifting support plate and the guide column. The guide sleeve is slidably connected to the guide column. The beneficial effects are: by setting a pressure transmitter, this utility model can detect the pressure of the polishing wheel on the cylindrical mirror substrate in real time, and then display it on a screen in real time. This provides accurate data reference for controlling the polishing pressure, ensuring the quality of polishing. Simultaneously, during the polishing process, the compression spring provides floating support for the movement of the polishing support and the polishing wheel, ensuring that the polishing wheel smoothly transitions along the surface of the cylindrical mirror substrate during polishing, thus smoothly polishing the cylindrical mirror substrate."

[0003] Although the cylindrical mirror substrate polishing device mentioned in the above patent documents has achieved the polishing effect of the cylindrical mirror substrate polishing device, it still has some shortcomings: the existing cylindrical mirror substrate polishing device can only polish one end of the cylindrical mirror when in use, resulting in low polishing efficiency, and a large amount of dust is generated during the polishing process, causing pollution to the surrounding environment, and may be inhaled by the operator, causing respiratory diseases.

[0022] Reference Figures 1 to 4As shown, this utility model provides a polishing device for miniature cylindrical mirrors, including: a base 1, two sets of polishing components on the upper side of the base 1, each polishing component including a fixing plate 11 and a sliding plate 12 slidably connected thereto, a hydraulic cylinder 14 mounted on the outer side of the fixing plate 11, a lifting frame 15 slidably connected to the inner side of the sliding plate 12, a polishing wheel 16 mounted on the inner end of the lifting frame 15, an electric push rod 17 mounted on the upper end of the lifting frame 15, and a dust collection box 3 on the upper side of the base 1.

The clamping assembly 2 includes a positioning plate 21. A clamping groove 22 is provided on the upper end of the positioning plate 21. A clamping plate 24 is provided on the upper side of the clamping groove 22. A flipping plate 23 is welded to the upper end of the clamping plate 24.

[0023] In this embodiment, the base 1, the polishing assembly, the clamping assembly 2, and the dust collection box 3 constitute the main structure of the polishing device for the micro cylindrical mirror involved in this application.

[0024] The base 1 has two parallel guide grooves on its upper surface, and the bottom of the slide plate 12 is welded with a guide slider, which is slidably connected in the guide groove.

[0025] The inner wall of the slide plate 12 is provided with a vertical limiting groove (T-shaped groove structure), and the outer end of the lifting frame 15 is provided with a limiting slider (T-shaped block structure), which is slidably connected in the limiting groove.

[0026] Specifically, the width of the clamping plate 24 is smaller than that of the clamping groove 22, and the lower end of the clamping plate 24 is provided with an anti-slip rubber buffer block, and the lower surface of the buffer block is provided with an arc-shaped groove.

[0027] Specifically, the longitudinal length of the polishing wheel 16 in the top view direction is less than the front and rear width of the dust collection box 3, and the polishing wheel 16 is located on the upper side of the dust suction port 31.

[0028] It should be noted that the hydraulic cylinder 14, the electric actuator 17, and the motor mentioned below are all electrically connected to the controller (microcontroller, etc.) inside the externally installed control box, and the start and stop operations of each device are realized through operation buttons.

[0029] like Figure 1 and Figure 2In the middle, the inner end of the lifting frame 15 is provided with an N-shaped groove, and the polishing wheel 16 is rotatably installed in the N-shaped groove. One end of the polishing wheel 16 is connected to a motor, which is fixed to the outer end of the lifting frame 15. The outer side of the slide plate 12 is connected to a horizontal guide rod 13, and the guide rod 13 slides through the fixed plate 11. The electric push rod 17 is vertically installed on the inner side wall of the slide plate 12, and the lower end of the piston rod of the electric push rod 17 is fixedly connected to the lifting frame 15 by bolts and nuts. The thickness of the positioning plate 21 is less than the axial length of the cylindrical mirror substrate, and the clamping groove 22 is designed as a U-shaped groove structure. The end of the flip plate 23 away from the hinge is provided with a locking bolt 25, and the locking bolt 25 is matched and connected to the threaded hole opened at the upper end of the positioning plate 21.

[0030] Specifically, the polishing wheel 16 is equipped with a spindle, and one end of the spindle rotates through the wall of the N-shaped groove and connects to the output shaft of the motor, so as to achieve the effect of the motor driving the polishing wheel 16 to rotate.

[0031] As another preferred embodiment, the clamping groove 22 can be provided with buffer pads of different thicknesses of the same shape, so that when clamping, the buffer pads of appropriate thickness can be selected according to the outer diameter of the cylindrical mirror, and a stable clamping effect can be achieved in conjunction with the clamping plate 24.

[0032] like Figure 1 and Figure 4 In the middle, the dust suction port 31 is designed as a bucket-shaped structure, and the upper edge of the bucket-shaped structure is welded and fixed to the upper end of the dust collection box 3 and the partition plate 36. The inner side wall of the connecting hole 33 is provided with a dust filter 32, and the lower side of the dust filter 32 and the bottom of the dust collection box 3 are provided with a pull-out groove 34 that communicates with the outside.

[0033] It should be noted that the polishing wheel 16 on the left rotates clockwise and the polishing wheel 16 on the right rotates counterclockwise, so that during polishing, dust and debris are centrifugally thrown downwards and outwards along the tangent of the rotation of the polishing wheel 16.

[0034] Specifically, the baffle 39 is kept tilted outward under the action of the elastic element 37 (which can be a spring). Then, when the lifting frame 15 descends, it contacts the baffle 39 and squeezes it downward, thereby blocking the dust thrown outward.

[0035] In use, first open the flip plate included in the clamping assembly, then place the cylindrical mirror horizontally in the clamping slot, and then reset the flip plate so that the clamping plate presses down onto the cylindrical mirror. Next, align the locking bolt with the threaded hole and rotate it downwards to lock the cylindrical mirror in place. Then, using the sliding plate, hydraulic cylinder, electric actuator, lifting frame, and polishing wheel included in the grinding assembly, both ends of the cylindrical mirror can be ground simultaneously. The position of the polishing wheel is easily adjustable, thus improving the grinding efficiency of the cylindrical mirror. The dust collection box is equipped with a suction port, dust filter, and suction holes. Under the action of the suction pump, a negative pressure suction effect is achieved inside the dust collection box. Dust falling on the upper side is then sucked in through the suction port and collected through a pull-out box. Simultaneously, baffles, arc rods, and elastic elements are used to block dust from the outside of the dust collection box, thus preventing dust pollution of the surrounding environment and harm to the operator.

[0036] The polishing device for miniature cylindrical mirrors of this invention can effectively solve the problems mentioned in the background technology. Based on the existing polishing device technology for miniature cylindrical mirrors, it can simultaneously polish both ends of the cylindrical mirror to improve work efficiency, and also has the effect of dust collection.
