Description

Technical Field

[0001] The utility model relates to the technical field of optical lens processing equipment, in particular to a lens centering and edge grinding machine with a stable transmission structure. Background Art

[0002] The lens centering and edge grinding machine is a mechanical equipment used for processing spectacle lenses. It is mainly used for edge grinding of spectacle lenses to meet different requirements for fitting glasses. The lens centering and edge grinding machine can be used to trim and process the edges of spectacle lenses so that the size, shape and surface quality of the spectacle lenses meet the requirements for fitting glasses. The lens centering and edge grinding machine usually adopts CNC technology, which can automate and precisely process spectacle lenses according to preset processing procedures and parameters, thereby improving processing efficiency and processing quality. The lens centering and edge grinding machine plays an important role in the manufacturing process of glasses and has a significant impact on the comfort and use effect of the glasses.

[0003] With the continuous advancement of science and technology, lens centering and edge grinding machines are also constantly updated. When processing lenses, existing lens centering and edge grinding machines need to use the clamping mechanisms on the left and right sides of the lens to clamp the lenses, and the clamping mechanisms on both sides of the lens need to be used to drive the lenses to rotate, thereby improving the edge grinding accuracy of the lenses. However, the driving assembly that drives the clamping mechanisms on the left and right sides of the lens to rotate is complex in structure, and often requires the provision of a motor, a synchronous drive connecting rod, and a plurality of gears. The plurality of gears are respectively connected to the clamping mechanisms on the left and right sides of the lens, and then the synchronous drive rod is used to connect the gears. Under the action of the rotation of the motor, the synchronous drive connecting rod is driven to rotate, so that the gears at both ends of the synchronous drive connecting rod rotate, thereby driving the clamping mechanisms on the left and right sides of the lens to rotate, and finally the clamping mechanism drives the lens to rotate. However, since the driving assembly structure is relatively complex, and the synchronous drive rod and a plurality of gears are required to drive the clamping mechanisms on both sides of the lens to rotate, it is easy to cause the transmission effect of the device to be unstable, affecting the edge grinding processing accuracy.

[0027] By providing a first driving device to drive the suction shaft and the adsorption device to rotate, and a second driving device to drive the clamping shaft to rotate, the overall structure of the device is simplified, effectively reducing the number of parts and the difficulty of assembly.

[0028] Furthermore, the adsorption device 32 is a vacuum adsorption head, and the vacuum device and the vacuum adsorption head cooperate to fix the workpiece on the vacuum adsorption head, and then the clamping shaft 41 is moved to cooperate with the clamping and fixing, which helps to improve the stability of workpiece processing.

[0030] Furthermore, a suction shaft housing is sleeved on the outer side of the suction shaft 31 , and the suction shaft 31 is installed on the mounting base 2 through the suction shaft housing.

The clamping shaft 41 approaches or moves away from the adsorption device 32 through the clamping adjustment component 5.

[0032] Furthermore, by providing the clamping adjustment component 5 to drive the clamping shaft 41 to move closer to or away from the adsorption device 32, it can be ensured that the distance and position between the workpiece and the clamping shaft 41 reach an optimal state, thereby improving the processing accuracy and quality.

[0033] Furthermore, the clamping adjustment assembly 5 drives the clamping shaft 41 to move relatively along the axial direction of the clamping shaft 41, which is beneficial to improving the stability of the clamping shaft 41 on the workpiece, so as to achieve better workpiece centering effect and higher edge grinding accuracy.

[0034] like Figures 1 to 4 The clamping adjustment assembly 5 shown includes a first clamping adjustment mechanism 51 connected to the clamping shaft 41, and the first clamping adjustment mechanism 51 drives the clamping shaft 41 to approach or move away from the adsorption device 32;

[0039] Furthermore, by arranging the first slide rail 511 and the first slide seat 512 to cooperate with each other, the friction and wear between the components can be reduced, and the service life of the device can be effectively extended.

[0040] Optionally, the first driving member 513 may be a telescopic air cylinder or a telescopic hydraulic cylinder.

[0041] Furthermore, the first driving member 513 is switched from the low-pressure state to the high-pressure state, and the first driving member 513 thereby drives the clamping shaft 41 to approach the adsorption device 32 to cooperate with the adsorption device 32 to clamp the workpiece.

[0050] Furthermore, the second driving member 52 drives the first clamping adjustment mechanism 51 to move through the second connecting mechanism 8, and the first clamping adjustment mechanism 51 drives the shaft housing 411 to move through the first connecting mechanism 7, so that the clamping shaft 41 is close to or away from the adsorption device 32.

One side of the first connecting clamping block 71 is sleeved on the outer side wall of the rotating shaft housing 411, and the other side of the first connecting clamping block 71 is connected to the first connecting portion 72.

[0052] Furthermore, the rotating shaft housing 411 passes through one side of the first connecting clamp block 71 , which can ensure the stability and reliability of the connection between the first connecting clamp block 71 and the rotating shaft housing 411 .

[0053] Furthermore, the other side of the first connecting clamp 411 is a "U"-shaped groove, the first connecting portion 72 is sleeved on the output end of the first clamping adjustment mechanism 51, the cross-section of the first connecting portion 72 is in an "I" shape, and the two sides of the first connecting portion 72 are clamped on the first connecting clamp 71 through grooves.

One side of the second connecting plate 81 is connected to the first clamping adjustment mechanism 51, and the other side of the second connecting plate 81 is connected to the second connecting portion 82.

[0055] Furthermore, by providing the second connecting plate 81 and the second connecting portion 82 in cooperation, the stability of the connection between the second driving member 52 and the first clamping adjustment mechanism 51 can be effectively ensured, and the power output by the second driving member 52 can be smoothly transmitted to the first clamping adjustment mechanism 51.

[0056] Furthermore, one side of the second connecting plate 81 is simultaneously connected to the first driving member 513 and the first slide seat 512, the output end of the first driving member 513 passes through the second connecting plate 81, the other side of the second connecting plate 81 is a "U"-shaped groove, and the second connecting part 82 is provided with symmetrically arranged circular plates, and the "U"-shaped groove is clamped between the two symmetrically arranged circular plates of the second connecting part 82.

[0057] like Figures 1 to 4 The mounting base 2 shown is provided with a reference block 21 , and the clamping shaft 41 is provided with a sensing device 4111 matched with the reference block 21 .

[0058] Optionally, the sensing device 4111 is a displacement sensor.

[0059] Specifically, when the lens needs to be processed, the lens is put into the centering and edging process. At this time, the displacement sensor obtains the value of the center thickness of the lens based on the distance from the reference block 21. Based on this value, when the second lens is processed, the device processes the second lens based on the reference value provided by the first lens, thereby obtaining the processed standard lens, which is conducive to achieving standardization of lens processing; secondly, this process is fully automated and does not require manual operation, which is conducive to saving labor costs.

The mounting base 2 is also provided with a first clamping adjustment mechanism 51 and a second driving member 52 for driving the clamping shaft 41 to approach or move away from the adsorption device 32. When the lens needs to be processed, the adsorption device 32 vacuum adsorbs and fixes the lens, and the first driving device 33 drives the adsorption device 32 to rotate through the suction shaft 31 so that the lens on the adsorption device 32 rotates. Similarly, the second driving device 42 drives the clamping shaft 41 to rotate. At this time, the second driving member 52 simultaneously drives the first clamping adjustment mechanism 51 and the clamping shaft 41 to move towards the adsorption device 32 to pre-clamp the lens, and then centering is performed, and then the clamping shaft 41 is driven by the first clamping adjustment mechanism 51 to move towards the adsorption device 32 to clamp and fix the lens, and finally the lens is processed by the edge grinding device on the frame.

The mounting base 2 is also provided with a first clamping adjustment mechanism 51 and a second driving member 52 for driving the clamping shaft 41 to move closer to or away from the adsorption device 32.
