Description

Technical Field

[0001] The invention relates to the technical field of lens processing, in particular to a manual double-grinding-wheel numerically controlled core extracting machine. Background Art

[0002] During the lens processing, a double-grinding-wheel horizontal CNC core-taking machine is used to perform rough and fine grinding of the lens, as well as square cutting and other processes.

[0003] The existing device can only use one grinding wheel to grind the lens. Considering efficiency and quality, neutral sand grain number is often used, which cannot improve efficiency and quality. It is very restrictive and has little room for process debugging. In order to use an optical centering device, a gear transmission method is used. The gear transmission method cannot be high-speed. High-speed cutting will cause vibration. Once vibration occurs during cutting, it will cause slight edge collapse of the lens. Summary of the invention

[0004] The problem solved by the present invention is to provide a manual horizontal CNC core extractor, which solves the problem that the existing device cannot perform two processes of rough grinding and fine grinding when grinding lenses. The existing core extractor can only use gears to drive the lens spindle when using an optical centering instrument. The waterproof cover of the existing core extractor cannot move left and right, and is fixed on the processing room mechanism, and can only grind with one grinding wheel. The existing core extractor uses a sleeve to slide the right lens shaft 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: The manual horizontal CNC core-taking machine comprises a manually movable right lens axis mechanism, a machine head mechanism, a left-right movable processing chamber cover mechanism, a hollow servo motor mechanism, an optical centering instrument mechanism, a first grinding wheel mechanism, and a second grinding wheel mechanism.

[0006] The base unit is equipped with a machine head base for lens processing, a manually movable right lens axis mechanism for manually clamping the lens, and a first grinding wheel mechanism and a second grinding wheel mechanism for coarse and fine grinding of the lens.

[0007] The processing chamber cover unit is equipped with an opening and closing cylinder, a waterproof cover, a guide rail for left and right movement, and a transparent plate.

[0008] The manual right lens moving mechanism unit is equipped with a clamping adjustment screw, a photoelectric switch for starting processing, a moving gear, a moving gear guide rail, a handle, a lower rack guide rail, a lower rack, a push rod for moving the right lens axis, and a right lens axis adjustment base plate.

[0009] The right lens shaft moving unit mechanism is equipped with a right lens shaft moving bottom plate, a right lens shaft moving guide rail, a right lens shaft driving servo hollow motor, a right lens shaft driving servo hollow motor support plate, a right lens shaft base, and a thickness measuring sensor on the right lens shaft side.

[0010] The left lens shaft mechanism unit is equipped with a hollow servo motor for driving the left lens shaft, a left lens shaft hollow mechanism, and a left lens shaft base.

[0011] The optical centering instrument mechanism is equipped with a light source for optical centering and a camera for optical centering.

[0012] The grinding wheel 2 unit mechanism is equipped with a Y-axis servo motor, a Y-axis screw, a Y-axis guide rail, a Y-axis base, an X-axis servo motor, an X-axis screw, an X-axis guide rail, an X-axis base, a grinding wheel electric spindle of the grinding wheel 2, a grinding wheel cover, and a grinding wheel base.

[0013] The grinding wheel 1 unit mechanism is equipped with a Y-axis servo motor, a Y-axis screw, a Y-axis guide rail, a Y-axis base, an X-axis servo motor, an X-axis screw, an X-axis guide rail, an X-axis base, a grinding wheel electric spindle of the grinding wheel 1, a grinding wheel cover, and a grinding wheel base.

[0014] Preferably, the manually movable right lens axis base mechanism is designed on the side of the right lens axis, which is easy to operate and more convenient to manually clamp the lens. The right lens axis mechanism utilizes the design concept of the guide rail slider, which improves the coaxiality while also simplifying the precision adjustment of the coaxiality, lowers the threshold for precision adjustment, and improves reliability.

[0015] Preferably, the waterproof cover mechanism of the processing room can be moved left and right, and has a large space when opened, which is convenient for taking out the lenses, has a better waterproof effect when closed, and is more stable when opened and closed.

[0016] Preferably, the optical centering mechanism utilizes a servo hollow motor, so that the light source of the centering instrument can be irradiated onto the lens through the 6mm inner hole of the hollow servo motor, and the centering instrument camera opposite can be used to manually adjust and confirm the lens eccentricity.

[0017] Preferably, the grinding wheel 2 unit mechanism adopts an independent screw guide rail movement mode and can perform alternating grinding with the grinding wheel 1.

[0018] The beneficial effects of the present invention are: the lens can be clamped and ground by manually moving the right lens axis mechanism, and a two-step process of roughing and finishing can be realized during the grinding process, thereby achieving high quality and high efficiency.

[0019] The waterproof cover of the processing room is moved by a guide rail slider, with good moving accuracy, and no leakage caused by misalignment. The two grinding wheels of grinding wheel 1 and grinding wheel 2 can be waterproofed.

[0020] The hollow light-transmitting structure of the centering instrument adopts the design of a servo hollow motor, which allows the light source to pass through the hollow hole of the servo motor, ensuring the direct drive effect of the servo motor and the lens shaft.
