Problems solved by technology

At present, the grinding of high-precision lenses mostly depends on large-scale automatic grinding equipment imported from abroad. Although high processing accuracy can be obtained, these equipment are bulky and complex in structure; especially expensive, each costing millions , or even tens of millions of yuan, which is unbearable for general large and medium-sized enterprises in this field; moreover, the operation technology of this kind of equipment is complicated, requiring high-level technicians to operate, and its reliability is poor, and the failure rate is high, which brings difficulties in personnel training for enterprises and increased production costs

Embodiment 1

[0025] like figure 1 , image 3 As shown, the optical lens grinding grinding head feed control device of the present invention includes a motor 2 for driving the grinding head to rotate and a sliding sleeve 1 for wearing the motor 2, and the motor 2 can freely move up and down in the sliding sleeve 1 Sliding, the sliding sleeve 1 is fixedly connected with the grinding machine base 10, and the lower output end of the motor 2 is connected with the grinding head 4 through the connecting rod 3. The pressure of the grinding head 4 is usually small when grinding optical lenses, especially in the fine grinding process, the gravity of the motor 2 is generally greater than the pressure required for the grinding of the grinding head 4, and when the pressure is too large, it is easy to cause the lens to be broken and the thickness This is especially true for smaller, more brittle lenses. Therefore, the present invention adopts the bottom of motor 2 to be provided with the precision con...

Embodiment 2

[0028] see figure 2 In this embodiment, as a further improvement on the basis of the technical solution of the first embodiment, a support roller 11 can be provided between the cam 5 and the bottom end surface of the motor 2 to reduce the frictional resistance between the cam 5 and the bottom end surface of the motor 2 , while reducing the wear of the bottom surface of the cam 5 and the motor 2, prolonging its service life. Certainly, the support roller 11 can be connected with the motor 2 by using a support or other structures.

Embodiment 3

[0030] like Figure 4 As shown, as a further improved embodiment, the telescopic hydraulic cylinder 12 can adopt a speed-adjustable hydraulic cylinder. The speed-adjustable liquid cylinder includes a piston 12-4, a piston rod 12-3, a liquid storage cylinder 12-2 and a working cylinder 12-1 located in the oil storage cylinder 12-2. The working cylinder 12-1 is a barrel-shaped structure with one end open, and the gap between its open end and the end cap 12-5 of the oil storage cylinder 12-2 forms an oil circulation channel. The closed end of the working cylinder 12-1 is connected with an adjusting screw rod 12-6, and the outer side of the oil storage cylinder 12-2 and the corresponding end cover 12-5 is connected with a support 12-7, and the adjustment screw rod 12-6 is connected with the oil storage cylinder 12-2. Connect with support 12-7, set left and right adjustment nuts 12-9, 12-8 on the adjustment screw rod 12-6, left and right adjustment nuts 12-9, 12-8 are respectively...

Abstract

The invention discloses a feeding control device for a grinding head of optical lens. The device comprises a motor for driving the grinding head to rotate, and a slide sleeve for penetrating installation of the motor; and a support precise control mechanism for controlling lifting of the grinding head is arranged at the bottom of the motor. The precise control mechanism includes a cam contacted with the bottom end surface of the motor, and a cam driving mechanism. The cam driving mechanism includes a transmission gear coaxially connected with the cam, and a rack engaged with the transmission gear; and a telescopic liquid cylinder for driving the rack to perform a reciprocating motion is arranged at one end of the rack. The device can precisely control the grinding speed and the pressure of the grinding head, can control the lens grinding error within + / -0.01 mm, can effectively prevent the damage of lenses in the grinding process, and can conveniently and randomly control and adjust the lifting speed of the grinding head.

Description

technical field [0001] The invention relates to the technical field of optical lens processing, in particular to an optical lens grinding head feed control device. Background technique [0002] With the continuous development and popularization of optical equipment and instruments, the use of optical lenses is becoming more and more extensive, and the consumption is also increasing. Therefore, the requirements for the production quality and production efficiency of optical lens processing are also getting higher and higher. The main process with the largest workload and the strongest correlation with its production quality in the production of optical lenses is grinding. In order to ensure the processing quality of the lens, the traditional lens grinding usually has two processes of rough grinding and fine grinding, and then grinding and polishing. The dimensional accuracy and optical performance of the lens produced by this process are poor, which is far from being able to ...
