Description

Technical Field

[0001] The present invention relates to the technical field of lens processing, and particularly to a manual and automatic integrated vertical double-grinding-wheel numerically controlled core cutting machine. Background Art

[0002] During the lens processing, rough grinding, fine grinding, and processes such as cutting into a square of the lens are realized by a manual and automatic integrated vertical numerically controlled core cutting machine with double grinding wheels. It is also possible to grind a lens simultaneously by taking advantage of the manual and automatic integrated vertical double grinding wheels, which can offset the resistance brought to the fixture by a single grinding wheel. The automatic machine can be used as a manual machine, which has a certain degree of flexibility in the case of some small batches and sample lenses.

[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 used, which cannot improve efficiency and quality, has great limitations, and has a very small space for process debugging. In order to use an optical centering instrument, a gear drive method is adopted. The gear drive method cannot run at high speed. Vibration will occur during high-speed cutting, and once vibration occurs during cutting, it will cause tiny chipping on the lens.

[0004] The existing equipment either feeds and takes the lens from the side, or from the front of the processing chamber, and there is no model that feeds and takes the lens from the back of the processing chamber. The ingenious design of this model can make the space in front of the processing chamber very large, and the function of repairing the fixture on the machine can be realized. Summary of the Invention

[0005] The problem solved by the present invention is to provide a manual and automatic integrated vertical double-grinding-wheel numerically controlled core cutting machine, 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 cutting machine uses an optical centering instrument, only a gear can be used to drive the lens spindle. The existing core cutting machine cannot realize the process of simultaneous grinding with double grinding wheels. The existing core cutting machine 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. The existing vertical core cutting machine cannot realize the function of repairing the fixture in front of the processing chamber.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A manual and automatic integrated vertical double-grinding-wheel numerically controlled core cutting machine includes an upper and lower lens shaft mechanism, a left grinding wheel mechanism, a right grinding wheel mechanism, a hollow servo motor mechanism, a transfer XY axis module mechanism, and a processing chamber XY module mechanism;

[0008] The upper and lower shaft mechanism unit is equipped with a hollow servo motor, a lens shaft seat, a sliding guide rail, a slider, and a downward pressure proportional valve cylinder mechanism;

[0009] The XY axis module mechanism for conveying is installed with an XY axis module for conveying, an XY module for the processing chamber, a positioning cylinder 1, and a positioning cylinder 2;

[0010] The left grinding wheel mechanism unit is installed with a left grinding wheel, a left X-axis guide rail, an electric spindle for the left grinding wheel shaft, a left Y-axis servo motor, a left Y-axis guide rail, and a left X-axis servo motor;

[0011] The right grinding wheel mechanism unit is installed with a right grinding wheel, a right X-axis guide rail, an electric spindle for the right grinding wheel shaft, a right Y-axis servo motor, a right Y-axis guide rail, and a right X-axis servo motor.

[0012] Preferably, the left and right grinding wheel mechanism units are designed on the left and right sides of the lens shaft, and can process one lens simultaneously, offsetting the resistance of the grinding wheel to the lens shaft and improving the service life of the fixture; at the same time, the processing efficiency is also increased by more than double.

[0013] Preferably, the XY axis module mechanism for conveying and the XY module mechanism for the processing chamber enable the lens to be taken and placed from the back of the processing chamber, increasing the space in the front of the processing chamber, where a tool holder for repairing the fixture can be installed; realizing the function that the vertical core-taking part can repair the fixture on the machine.

[0014] Preferably, for the up and down axis mechanism, a servo hollow motor is utilized, allowing the light source of the centering instrument to irradiate the lens through the 6mm inner hole of the hollow servo motor, and performing manual adjustment and confirmation of the lens eccentricity with the centering instrument camera on the opposite side.

[0015] Preferably, the manual-automatic integrated vertical numerically controlled core-taking machine can be used as an automatic machine or a manual machine, having a certain degree of flexibility.

[0016] The beneficial effects of the present invention are: by using the left and right grinding wheels on both sides of the lens shaft to grind one lens simultaneously, the resistance of the grinding wheel to the lens is offset, improving the service life of the fixture and also enhancing the processing efficiency.

[0017] The servo motors of the upper and lower lens shafts adopt a hollow design, 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 while realizing the function of optical centering.

[0018] The automatic machine can also install a tool holder in front of the processing chamber to trim the fixture. Description of the Drawings
