Description

Technical Field

[0001] The present invention relates to the technical field of lens processing, and in particular to a manual foot-operated vertical double-grinding-wheel numerically controlled core cutter. Background Art

[0002] During the lens processing, rough grinding, fine grinding, and processes such as cutting into a square of the lens are achieved through a double-grinding-wheel vertical numerically controlled core cutter. It is also possible to simultaneously grind a lens by taking advantage of the double-grinding-wheel vertical structure, which can offset the clamping resistance brought by a single grinding wheel.

[0003] When the existing device grinds a lens, only one grinding wheel can be used for grinding. Considering efficiency and quality, a neutral grit size is often adopted, which cannot improve efficiency and quality, has great limitations, and has very little room for process debugging. In order to use an optical centering instrument, a gear drive method is adopted. The gear drive method cannot achieve high speed, and vibration will occur during high-speed cutting. Once vibration occurs during cutting, it will cause small chipping on the lens. Summary of the Invention

[0004] The problem solved by the present invention is to provide a manual foot-operated vertical double-grinding-wheel numerically controlled core cutter, which solves the problem that the existing device cannot perform two processes of rough grinding and fine grinding when grinding a lens. When the existing core cutter uses an optical centering instrument, it can only drive the lens spindle by gears. The existing core cutter cannot achieve the process of simultaneous grinding of two grinding wheels. The existing core cutter uses a method of sliding the right lens shaft with a bushing to clamp the lens, and the coaxiality cannot be maintained for a long time, and the repair is difficult and costly.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A manual foot-operated vertical double-grinding-wheel numerically controlled core cutter includes a manual foot-operated mechanism, a left grinding-wheel mechanism, a right grinding-wheel mechanism, a hollow servo motor mechanism, and an optical centering instrument mechanism;

[0007] The manual foot-operated mechanism unit is equipped with a foot pedal mechanism unit, a foot pedal chain, a foot pedal gear, a foot pedal mechanism handle gear, a foot pedal mechanism handle connecting rod, a foot pedal mechanism connecting rod, a foot pedal mechanism platform, a foot pedal mechanism check hook, and a foot pedal mechanism check piece;

[0008] The manual foot-operated moving upper lens shaft mechanism unit is equipped with a hollow servo motor mechanism unit, an upper lens shaft seat unit, and an upper lens shaft guide rail;

[0009] The left grinding-wheel mechanism unit is equipped with a left grinding wheel, a left X-axis guide rail, a left grinding-wheel shaft electric spindle, a left Y-axis servo motor, a left Y-axis guide rail, and a left X-axis servo motor.

[0010] The right grinding wheel mechanism unit is equipped with a right grinding wheel, a right X-axis guide rail, a right grinding wheel shaft electric spindle, a right Y-axis servo motor, a right Y-axis guide rail, and a right X-axis servo motor.

[0011] Preferably, the manual foot-operated moving mechanism unit is designed in front of the processing chamber for easy operation. It is more convenient to manually hold the lens. The upper lens shaft mechanism utilizes the design concept of guide rail sliders, improving the coaxiality while simplifying the precision adjustment of coaxiality, lowering the threshold of precision adjustment, and enhancing the reliability.

[0012] Preferably, the left and right grinding wheel mechanisms enable the left and right grinding wheels to simultaneously process a lens, offsetting the resistance of the grinding wheel to the lens, improving the processing efficiency while extending the service life of the fixture.

[0013] Preferably, the upper and lower shaft mechanism utilizes a servo hollow motor, allowing the light source of the centering instrument to irradiate the lens through the 6mm inner hole of the hollow servo motor for manual adjustment and confirmation of the lens eccentricity with the centering instrument camera on the opposite side.

[0014] The beneficial effects of the present invention are as follows: By manually foot-operating the upper lens shaft to hold the lens, during the grinding process, the two-process flow of roughing and finishing can be achieved, and the left and right grinding wheels can also simultaneously grind a lens. Thus, high-quality and high-efficiency are realized.

[0015] The hollow light transmission of the upper and lower shaft mechanism adopts the design of a servo hollow motor, allowing the light source to pass through the hollow hole of the servo motor, ensuring the direct drive effect between the servo motor and the lens shaft.

[0016] The design of the manual foot operation enables an operator to grind a large-diameter lens. The operator holds the lens with both hands, steps on the pedal to lift the upper lens shaft mechanism, places the large-diameter lens, can perform centering with the optical centering instrument, and after confirmation, enters the clamping of the processing pressure for processing.

[0017] It is possible to install a tool rest in front of the processing chamber to trim the fixture. BRIEF DESCRIPTION OF THE DRAWINGS
