Description

Technical Field

[0001] This utility model relates to the field of optical lens processing equipment technology, and in particular to a beveling machine. Background Technology

[0002] In recent years, high-precision optical lenses have been widely used in many fields, and the requirements for both quality and quantity are increasing daily, exceeding the capabilities of traditional optical manufacturing. Therefore, improving the surface quality and production efficiency of optical lenses has become a challenging problem.

[0003] High-precision optical lens processing generally involves two processes: grinding and polishing, with grinding preceding polishing. Beveling is a small step between grinding and polishing, where the edges of the optical lens are rounded using a grinding wheel. Traditionally, beveling is done manually by highly experienced workers, requiring skilled operation but resulting in low efficiency. Existing beveling machines (such as the lens beveling machine disclosed in application number 202420995914.5) require a drive mechanism to move the clamping assembly away from the grinding wheel when mounting the lens, and then again to move it closer to the grinding wheel when grinding the lens. This clamping structure tends to be time-consuming when mounting the lens. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a beveling machine to solve the technical problem that the existing beveling machine takes a long time to clamp the lens.

[0005] To achieve the above technical objectives, the present invention provides a beveling machine, comprising:

[0006] A chamfering mechanism, comprising a rotatable grinding wheel;

[0007] A clamping mechanism is disposed directly above the grinding wheel. It includes a clamping wheel, a clamping member, an elastic member, and a driving assembly. The end face of the clamping wheel and the end face of the grinding wheel form a V-shaped angle. The clamping end of the clamping member is located within the V-shaped angle. The elastic member is connected to the clamping member so that the clamping end of the clamping member abuts against the end face of the clamping wheel. The driving assembly is connected to the clamping wheel and is used to drive the clamping wheel to rotate.

[0008] Furthermore, the grinding wheel is inclined relative to the horizontal plane, and the clamping wheel is vertically arranged relative to the horizontal plane.

[0009] Furthermore, the chamfering mechanism also includes a first rotation drive member, the output end of which is coaxially and fixedly connected to the grinding wheel for driving the grinding wheel to rotate.

[0010] Furthermore, the included angle of the V-shape is 30°–60°.

[0011] Furthermore, the clamping member includes a clamping head, an arc-shaped segment, and at least two straight rod segments. The clamping head and the arc-shaped segment are both located within the V-shaped angle. The clamping head is concentric with the clamping wheel and is fixedly connected to one end of the arc-shaped segment. Each of the straight rod segments is disposed on the side of the clamping wheel and is perpendicular to the end face of the clamping wheel. The middle portions of adjacent straight rod segments are fixedly connected to each other. One end of any straight rod segment is fixedly connected to the other end of the arc-shaped segment. Each straight rod segment can move along the axial direction of the clamping wheel. Each elastic element is connected to the other end of each straight rod segment in a corresponding manner, so that the clamping head abuts against the end face of the clamping wheel.

[0012] Furthermore, the clamp also includes at least two end caps, each end cap being detachably and fixedly connected to the other end of each straight rod segment, the diameter of the end cap being larger than the diameter of the straight rod segment, and each elastic element being connected to each end cap in a one-to-one correspondence.

[0013] Furthermore, the clamp also includes a mounting base, on which at least two guide channels are provided, each extending axially along the clamping wheel. The other end of each straight rod segment slides through each guide channel in a corresponding manner. Each elastic element is fitted onto each straight rod segment in a corresponding manner. One end of the elastic element abuts against the mounting base, and the other end of the elastic element abuts against the end cap.

[0014] Furthermore, the drive assembly includes a rotating shaft and a second rotation drive component. One end of the rotating shaft is coaxially and fixedly connected to the clamping wheel, and the output end of the second rotation drive component is coaxially and fixedly connected to the other end of the rotating shaft, for driving the rotating shaft to rotate.

[0015] Furthermore, the chamfering machine also includes a moving mechanism, which is disposed on the side of the grinding wheel and connected to the clamping mechanism, for driving the clamping mechanism to move closer to or further away from the grinding wheel, so as to adjust the distance between the clamping wheel and the end face of the grinding wheel.

[0016] Furthermore, the moving mechanism includes a moving frame, a support frame, and a driving component. The upper end of the moving frame is fixedly connected to the mounting base and the second rotating driving component, and the lower end of the moving frame is slidably connected to the support frame. The driving component is connected to the moving frame and is used to drive the moving frame to move closer to or away from the grinding wheel along the axial direction of the clamping wheel.

[0017] Compared with the prior art, the beneficial effects of this utility model include: when clamping the lens, a force away from the clamping wheel is applied to the clamping end of the clamping member, the lens to be chamfered is placed between the clamping wheel and the clamping end of the clamping member, the clamping end of the clamping member is released, and under the action of the elastic member, the clamping end of the clamping member and the clamping wheel clamp the lens together. When removing the lens, only a slight upward force needs to be applied to the lens to remove it from between the clamping end of the clamping member and the clamping wheel. This chamfering machine can realize the rapid clamping of the lens and solve the problem of the long time spent on clamping the lens in traditional chamfering machines. Attached Figure Description

The driving assembly 240 is connected to the clamping wheel 210 and is used to drive the clamping wheel 210 to rotate.

[0024] When clamping the lens, a force away from the clamping wheel 210 is applied to the clamping end of the clamp 220. The lens to be chamfered is placed between the clamping wheel 210 and the clamping end of the clamp 220. The clamping end of the clamp 220 is released. Under the action of the elastic member 230, the clamping end of the clamp 220 and the clamping wheel 210 clamp the lens together. When removing the lens, only a slight upward force needs to be applied to the lens to remove it from between the clamping end of the clamp 220 and the clamping wheel 210.

[0025] As a preferred embodiment, please refer to Figure 2 and Figure 3 The grinding wheel 110 is inclined relative to the horizontal plane, and the clamping wheel 210 is vertically arranged relative to the horizontal plane, so that the end face of the clamping wheel 210 and the end face of the grinding wheel 110 form the V-shaped angle, and the grinding wheel 110 is inclined to facilitate the powder on the grinding wheel 110 to slide off.

[0026] As a preferred embodiment, please refer to Figure 1 and Figure 2 The chamfering mechanism 100 further includes a first rotation drive 120. The output end of the first rotation drive 120 is coaxially and fixedly connected to the grinding wheel 110 for driving the grinding wheel 110 to rotate. By operating the first rotation drive 120, the output end of the first rotation drive 120 can drive the grinding wheel 110 to rotate, thereby enabling the grinding wheel 110 to grind the edge of the lens. The first rotation drive 120 can be directly connected to the grinding wheel 110 using a suitable type of motor, or it can be indirectly connected to the grinding wheel 110 using a gear set or a pulley set.

[0027] As a preferred embodiment, please refer to Figure 2 The V-shaped angle is 30°–60°, which makes the edge curvature of the lens 30°–60°.

[0028] As a preferred embodiment, please refer to Figure 2 and Figure 3 The clamp 220 includes a clamping head 221, an arc-shaped segment 222, and at least two straight rod segments 223. The clamping head 221 and the arc-shaped segment 222 are both located within the V-shaped angle. The clamping head 221 is concentric with the clamping wheel 210 and fixedly connected to one end of the arc-shaped segment 222. Each straight rod segment 223 is disposed to the side of the clamping wheel 210 and is perpendicular to the end face of the clamping wheel 210. Adjacent straight rod segments 223 are fixedly connected to each other at their midpoints. One end of the straight rod segment 223 is fixedly connected to the other end of the arc segment 222. Each straight rod segment 223 can move along the axial direction of the clamping wheel 210. Each elastic element 230 is connected to the other end of each straight rod segment 223 in a corresponding manner, so that the clamping head 221 abuts against the end face of the clamping wheel 210. The structure of the clamp 220 ensures that there is no interference between the clamping end of the clamp 220 and the grinding wheel 110 and the clamping wheel 210.

[0029] In a preferred embodiment, the clamping head 221 is a rubber head, which can prevent damage to the lens.

[0030] As a preferred embodiment, please refer to Figure 3 The clamp 220 further includes at least two end caps 224, each end cap 224 being detachably and fixedly connected to the other end of each straight rod segment 223. The diameter of the end cap 224 is larger than the diameter of the straight rod segment 223. Each elastic member 230 is connected to each end cap 224 in a one-to-one correspondence, which facilitates the installation of the elastic member 230.

[0031] As a preferred embodiment, please refer to Figure 3 The clamp 220 also includes a mounting base 225, which has at least two guide channels that extend axially along the clamping wheel 210. The other end of each straight rod segment 223 slides through the guide channel. Each elastic element 230 is fitted onto each straight rod segment 223. One end of the elastic element 230 abuts against the mounting base 225, and the other end abuts against the end cap 224. The mounting base 225 can guide the straight rod segments 223, and the multiple straight rod segments 223 can prevent the clamp 220 from rotating.

[0032] As a preferred embodiment, please refer to Figure 1 and Figure 2The drive assembly 240 includes a rotating shaft 241 and a second rotation drive member 242. One end of the rotating shaft 241 is coaxially and fixedly connected to the clamping wheel 210. The output end of the second rotation drive member 242 is coaxially and fixedly connected to the other end of the rotating shaft 241, and is used to drive the rotating shaft 241 to rotate. By operating the second rotation drive member 242, the second rotation drive member 242 can drive the rotating shaft 241 to rotate, and drive the clamping wheel 210 to rotate, thereby driving the lens to rotate, realizing the beveling of one edge of the lens. When it is necessary to beveling the other edge of the lens, it is only necessary to manually flip the lens and clamp it again.

[0033] As a preferred embodiment, please refer to Figure 1 and Figure 2 The beveling machine further includes a moving mechanism 400, which is disposed on the side of the grinding wheel 110 and connected to the clamping mechanism 200. It is used to drive the clamping mechanism 200 to move closer to or further away from the grinding wheel 110 to adjust the distance between the clamping wheel 210 and the end face of the grinding wheel 110, so that the clamping mechanism 200 can clamp lenses of different diameters. This beveling machine can beveling lenses of different diameters.

[0034] As a preferred embodiment, please refer to Figure 1 and Figure 2 The moving mechanism 400 includes a support frame 410, a moving frame 420, and a driving component 430. The upper end of the moving frame 420 is fixedly connected to the mounting base 225 and the second rotation driving component 242, and the lower end of the moving frame 420 is slidably connected to the support frame 410. The driving component 430 is connected to the moving frame 420 and is used to drive the moving frame 420 to move closer to or away from the grinding wheel 110 along the axial direction of the clamping wheel 210. When it is necessary to grind lenses of different diameters, the driving component 430 is operated. The 30 drives the movable frame 420 to move closer to or away from the grinding wheel 110 along the axial direction of the clamping wheel 210, thereby causing the clamping wheel 210 to move closer to or away from the grinding wheel 110 along its own axial direction. When the clamping wheel 210 moves closer to the grinding wheel 110, the distance between the end faces of the clamping wheel 210 and the grinding wheel 110 decreases, which allows for chamfering of lenses with smaller diameters. When the clamping wheel 210 moves away from the grinding wheel 110, the distance between the end faces of the clamping wheel 210 and the grinding wheel 110 increases, which allows for chamfering of lenses with larger diameters.

[0035] As a preferred embodiment, please refer to Figure 1The lower end of the movable frame 420 is provided with a screw hole. The driving component 430 is a screw rod. The screw rod is perpendicular to the end face of the clamping wheel 210. The screw rod passes through the screw hole and is screwed into the screw hole. By rotating the screw rod in the forward or reverse direction, since the screw rod is screwed into the screw hole and the movable frame 420 is limited by the support frame 410, when the screw rod rotates in the forward or reverse direction, the movable frame 420 will move closer to or away from the grinding wheel 110 along the axial direction of the clamping wheel 210.

[0036] As a preferred embodiment, please refer to Figure 1 and Figure 2 The beveling machine also includes a water supply mechanism 500, which is used to add water to the surface of the grinding wheel 110. The mechanism includes a water tank 510, a water pipe and a drive pump. The grinding wheel 110 is disposed in the water tank 510. One end of the water pipe faces the surface of the grinding wheel 110. The outlet end of the drive pump is connected to the other end of the water pipe to pump water into the water pipe. This can cool the grinding wheel 110 and wash off the powder on the surface of the grinding wheel 110.

[0037] As a preferred embodiment, please refer to Figure 2 The water tank 510 has a drain outlet 511 for draining water.

[0038] To better understand this utility model, the following is combined with... Figure 1 - Figure 3 The working principle of the technical solution of this utility model will be described in detail below:

[0039] When clamping the lens, the distance between the end faces of the clamping wheel 210 and the grinding wheel 110 is adjusted in advance according to the diameter of the lens to be chamfered. By rotating the screw in either the forward or reverse direction, since the screw is screwed into the screw hole and the moving frame 420 is limited by the support frame 410, when the screw rotates in either direction, the moving frame 420 will move closer to or away from the grinding wheel 110 along the axial direction of the clamping wheel 210. This can drive the clamping wheel 210 to move closer to or away from the grinding wheel 110 along its own axial direction. When the clamping wheel 210 moves closer to the grinding wheel 110, the distance between the end faces of the clamping wheel 210 and the grinding wheel 110 decreases, allowing for chamfering of smaller diameter lenses. When the clamping wheel 210 moves away from the grinding wheel 110, the distance between the end faces of the clamping wheel 210 and the grinding wheel 110 decreases. The increased distance between the end faces of the clamping wheel 210 and the grinding wheel 110 allows for chamfering of lenses with larger diameters. When the distance between the end faces of the clamping wheel 210 and the grinding wheel 110 is adjusted to a preset value, a force away from the clamping wheel 210 is applied to the clamping head 221 of the clamping member 220. The lens to be chamfered is placed between the clamping wheel 210 and the clamping head 221. The clamping head 221 is released, and under the action of the elastic member 230, the clamping head 221 and the clamping wheel 210 clamp the lens together. When removing the lens, only a slight upward force needs to be applied to the lens to remove it from between the clamping head 221 and the clamping wheel 210. This chamfering machine can achieve rapid lens clamping, solving the problem of long clamping time in traditional chamfering machines.

[0040] The beveling machine provided by this utility model has the following beneficial effects:

[0041] (1) Apply a force away from the clamping wheel 210 to the clamping head 221 of the clamping member 220, place the lens to be chamfered between the clamping wheel 210 and the clamping head 221, release the clamping head 221, and under the action of the elastic member 230, the clamping head 221 and the clamping wheel 210 clamp the lens together. When removing the lens, only a slight upward force needs to be applied to the lens to remove the lens from between the clamping head 221 and the clamping wheel 210.

[0042] (2) When the clamping wheel 210 is close to the grinding wheel 110, the distance between the end face of the clamping wheel 210 and the grinding wheel 110 decreases, which can be used to bevel the edge of a lens with a smaller diameter. When the clamping wheel 210 is far away from the grinding wheel 110, the distance between the end face of the clamping wheel 210 and the grinding wheel 110 increases, which can be used to bevel the edge of a lens with a larger diameter.

[0043] (3) This edge-bending machine can quickly clamp the lens, solving the problem that traditional edge-bending machines take a long time to clamp the lens.
