Description

Technical Field

[0001] The invention relates to the technical field of optical glass processing equipment, and in particular to a double-cavity photoelectric controlled equal pressure detection device. Background Art

[0002] When processing optical lenses, polishing machines are generally used. The polishing machines in the prior art mainly consist of the following parts: a spindle, a spindle motor connected to the spindle for driving the spindle to rotate, and a ball mill installed on the spindle; a swing frame is also provided on the body of the polishing machine, a swing rod is fixedly provided on the swing frame, and a stylus is provided at the end of the swing rod; and the stylus on the swing rod is pressed tightly against the upper mold by a set cylinder, so that the optical lens installed on the mold is ground on the ball mill; and the swing amplitude of the stylus on the swing frame is adjusted by a set cam mechanism.

[0003] However, the swing amplitude of the existing optical grinding and polishing machine changes with the lens R. When the lens is at different positions on the ball mill, the force on the lens is different under the same pressure conditions. Figure 1 As shown, the curvature radius of the processed lens is inconsistent with the expected value, resulting in local deviations. When the lens is tested for PV through an interferometer, the local differences vary greatly.

[0004] The main reason is that the forces on the lens at the center and edge of the ball mill are different. When the lens is at the center of the ball mill, the stylus is perpendicular to the tangent of the ball mill. However, when the lens is located at the left or right edge of the ball mill, the stylus is still vertically downward. At this time, the force on the lens will change, and the lens will be unevenly stressed during the grinding process.

[0005] In order to further ensure the processing quality of the lens, a hydraulic or pneumatic system is generally used. When transmitting pressure through the gas (liquid) medium, it is necessary to ensure that the pressure at the output end and the input end are consistent. The pressure value needs to be detected and a timely alarm is issued when abnormal pressure occurs. Summary of the invention

[0006] The purpose of the present invention is to provide a dual-chamber photoelectric controlled equal pressure detection device, which mainly detects through photoelectricity to ensure that the pressure of the gas (liquid) pressure system remains consistent during operation. When the pressure is abnormal, an alarm can be issued in time to remind workers to quickly troubleshoot.

DETAILED DESCRIPTION

[0025] The present invention is further described below in conjunction with embodiments, which are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, other embodiments obtained by ordinary technicians in the field without creative work are all within the scope of protection of the present invention.

[0026] Embodiment 1

[0027] Before the present invention is elaborated in detail, the swing arm device for optical grinding and polishing machine is first described. The present invention is mainly used to detect whether the forces of the actuator cylinder I5 and the actuator cylinder II6 in the swing arm device are consistent. The swing arm device has the following structure: it includes a swing frame 1, a swing arm 2 and a stylus 3. The swing frame 1 is installed on the frame of the grinding and polishing machine. The swing frame 1 is connected to a cam mechanism for driving the swing frame 1 to swing back and forth. The cam mechanism is connected to a driving motor for driving the swing frame 1 to rotate.

[0028] A swing rod housing 4 is fixedly mounted on the swing frame 1, and the swing rod 2 is rotatably mounted in the swing rod housing 4. After the swing rod 2 extends out of the swing rod housing 4, one end is used to fix the stylus 3, and the other end is connected to a driving component, and the driving component is used to drive the swing rod 2 to rotate in the swing rod housing 4;

[0029] The driving assembly includes an actuator cylinder Ⅰ5 and an actuator cylinder Ⅱ6. One end of the actuator cylinder Ⅰ5 and the actuator cylinder Ⅱ6 are connected to the swing frame 1, and the other end is connected to the swing rod 2. The rotation amount of the swing rod 2 is controlled by controlling the extension and contraction of the actuator cylinder Ⅰ5 and the actuator cylinder Ⅱ6. The extension / contraction amount of the actuator cylinder Ⅰ5 is the same as the contraction amount / extension amount of the actuator cylinder Ⅱ6.

[0030] The rocker arm 2 is fixedly mounted in the rocker arm housing 4 via a bearing 7 .

[0031] In this embodiment, the actuator cylinder I5 and the actuator cylinder II6 are connected to the swing frame 1 and the swing rod 2 in a hinged manner.

[0032] It is further defined that the actuator cylinder I5 and the actuator cylinder II6 are hingedly connected to the swing frame 1 and the swing rod 2 via hinges or spindles.

[0033] In actual use, a vertical rod 8 is provided at the end of the swing rod 2 , and the actuator cylinder I5 and the actuator cylinder II6 are connected to the swing rod 2 by being hinged to the vertical rod 8 .

[0034] It should be noted that the actuator cylinder I5 and the actuator cylinder II6 are air cylinders or hydraulic cylinders. In this embodiment, the actuator cylinder I5 and the actuator cylinder II6 are hydraulic cylinders. The actuator cylinder I5 and the actuator cylinder II6 are connected to a liquid pump, and the liquid pump is used to drive the actuator cylinder I5 and the actuator cylinder II6 to extend or shorten.

[0035] It should be noted that the cam mechanism is mainly used to adjust the swing amplitude of the swing rod 2, and it can adopt the structure in the prior art, which will not be described here one by one.

[0036] In this way, in actual use, when the swing arm 2 is swinging, under the action of the actuator cylinder Ⅰ5 and the actuator cylinder Ⅱ6, the swing arm 2 will swing, when the actuator cylinder Ⅰ5 is extended, the actuator cylinder Ⅱ6 will be shortened, and when the actuator cylinder Ⅰ5 is shortened, the actuator cylinder Ⅱ6 will be extended; the actuator cylinder Ⅰ5 and the actuator cylinder Ⅱ6 realize synchronous movement; the swing arm 2 is more stable when rotating; in actual use, it can be ensured that when the lens 27 moves to the leftmost and rightmost ends of the ball mill 26, the stylus 3 can always maintain an angle of 90° with the ball mill 26. During the processing of the lens 27, compared with the polishing machine in the prior art, it has the advantage of uniform force during the processing of the lens 27, and can ensure the quality of the processed lens 27.

[0037] The main purpose of the present invention is to detect the extension and shortening of the actuator cylinder I5 and the actuator cylinder II6. The extension of one and the shortening of the other can be synchronized. The extension and shortening of the actuator cylinder I5 and the actuator cylinder II6 are the same, thereby ensuring the stability of the rocker arm 2.

[0038] The actuator cylinder I5 and the actuator cylinder II6 are connected to the double-chamber photoelectric control equal pressure detection device described in the present invention, which is used to detect and adjust the pressure of the actuator cylinder I5 and the actuator cylinder II6, and keep the pressure of the actuator cylinder I5 and the actuator cylinder II6 consistent.

[0039] The structure of the double-chamber photoelectric control equal pressure detection device is as follows:

[0040] The device comprises a housing 9, a first cavity 10 and a second cavity 11 are arranged in the housing 9, an installation area 12 is arranged between the first cavity 10 and the second cavity 11, an optoelectronic component 13 is arranged in the installation area 12, and the optoelectronic component 13 comprises a light source transmitter, a spectrometer, an optical receiver and an optical processor, and the optical receiver is connected to the optical processor;

[0041] A first piston 14 and a second piston 15 in an "I" shape are slidably arranged in the first cavity 10 and the second cavity 11, a grating ruler 16 is arranged in the middle of the first piston 14 and the second piston 15, and a notch 17 is arranged on the side walls of the first cavity 10 and the second cavity 11. The light source emitted by the light source transmitter is split by a spectrometer, wherein one beam of light is irradiated on the grating ruler 16 arranged on the first piston 14, and the other beam of light is irradiated on the grating ruler 16 arranged on the second piston 15. The light is reflected by the grating ruler 16 to the light receiver, and the light receiver transmits the light signal to the light processor, and the light processor is connected to an alarm;

[0042] The first cavity 10 is provided with a first inlet 18 and a first outlet 19 , and the second cavity 11 is provided with a second inlet 20 and a second outlet 21 . The first outlet 19 is connected to the second inlet 20 via a connecting pipe 22 .

[0043] For further optimization, a flow regulating valve 23 is provided on the connecting pipe 22 ; the flow regulating valve 23 is used to adjust the flow rate, thereby controlling the deflection speed of the vertical rod 8 , and thereby controlling the rotation speed of the swing rod 2 .

[0044] The first inlet 18 is used to connect with the actuator cylinder I5 , and the second outlet 21 is used to connect with the actuator cylinder II6 .

[0045] Further optimization is carried out, the cross-section of the first cavity 10 and the second cavity 11 is elliptical, and the upper and lower ends of the first piston 14 and the second piston 15 have an elliptical portion that is the same as the cross-sectional shape of the first cavity 10 and the second cavity 11. This can make the first piston 14 and the second piston 15 more stable when moving, and can play a guiding role to prevent deflection during movement, which causes the grating scale 16 to fail to reflect light normally after shifting, thereby affecting the detection accuracy.

[0046] Among them, glass 24 is provided at the gap 17 to seal the gap 17 .

[0047] In actual use, the first inlet 18 and the second outlet 21 are installed with quick connectors 25, which makes the connection more convenient and improves the connection efficiency.

[0048] The first cavity 10 and the second cavity 11 are of the same size; the first piston 14 and the second piston 15 move synchronously.

[0049] In this way, in actual use, the actuator cylinder I5 and the actuator cylinder II6 can use one liquid pump, the actuator cylinder I5 is connected to the first inlet 18, the actuator cylinder II6 is connected to the second outlet 21, and the actuator cylinder I5 and the actuator cylinder II6 are connected to each other through a liquid pump; in this way, in actual use, the movement of the actuator cylinder I5 and the actuator cylinder II6 can be detected, so that the pressure of the actuator cylinder I5 and the actuator cylinder II6 are kept consistent, the actuator cylinder I5 and the actuator cylinder II6 move synchronously, so that the extension / contraction of the actuator cylinder I5 is the same as the contraction / extension of the actuator cylinder II6, and when the pressure is inconsistent, an alarm can be issued to facilitate timely adjustment.

[0050] When the two beams of light shine on the same position of the grating ruler 16, the alarm will not sound an alarm; only when the two beams of light shine on different positions on the grating ruler 16, the alarm will sound an alarm, which serves as an alarm prompt and is also convenient for the staff to make timely adjustments, thereby ensuring that the actuator cylinder I5 and the actuator cylinder II6 are subjected to consistent force.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.
