Description

Technical Field

[0001] The utility model relates to the technical field of fixing devices, in particular to a fixing device for processing glass lenses. Background Art

[0002] Glass lenses are a commonly used optical material and are widely used in eyeglass manufacturing and various optical instruments. During the production and processing of glass lenses, they need to be coated to increase protection for the glass lens surface and prevent scratches and wear during use. During the coating process of the glass lenses, a fixed clamping device is required to fix the glass lenses. China has authorized a utility model patent (Announcement No.: CN220473721U) to disclose a fixed clamping device for glass lens coating. The device can automatically adapt and produce deformation and is suitable for glass lens bodies of different diameters. The clamping force is provided by the elastic force of the spring, and the clamping force will not be too large or too small.

[0003] However, the above device still has some shortcomings when used: specifically, in the prior art, when unloading after processing is completed, it is necessary to press the clamping parts one by one to squeeze the spring, thereby removing the fixed glass lens. This process is relatively labor-intensive, and a single operation can only complete the removal of a single lens, which is inefficient and not conducive to improving work efficiency. Therefore, in response to the above situation, a fixing device for glass lens processing is proposed. Utility Model Content

[0004] The utility model provides a fixing device for processing glass lenses, which has the advantages of higher unloading efficiency and lower working intensity.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A fixing device for processing a glass lens comprises a base plate. A mounting ring is arranged on the top of the base plate. A first clamping ring and a second clamping ring are arranged on the mounting ring. The number of the mounting rings is several.

[0007] There are two slide grooves on the top of the bottom plate. Slide blocks are slidably fitted in the two slide grooves. A protrusion is provided on the top of the slide block. The top of the protrusion is fixedly connected to the bottom of the fixed rod. There are several protrusions.

[0008] Several first clamping rings are symmetrically provided with connecting rods with the circle of the mounting ring as the midpoint. The shape of the connecting rods is an inverted "U" shape. The bottoms of several connecting rods located on the same side are fixedly connected to fixing rods. There are two fixing rods, and the two fixing rods are fixedly connected to arc rods.

[0009] Preferably, a positioning hole is provided on the bottom plate.

[0010] Preferably, the arc-shaped rod has an arc-shaped protrusion, the arc-shaped protrusion has a through-hole, a positioning pin is fitted in the through-hole, and the positioning pin cooperates with the positioning hole.

[0011] Preferably, a circular cavity is opened on the inner wall of the mounting ring, a spring is arranged in the circular cavity, one end of the spring is fixed to the cylinder, the cylinder and the circular cavity are gap-fitted, and the end of the cylinder away from the spring is fixed to the first clamping ring.

[0012] Preferably, the first clamping ring and the second clamping ring have the same structure, and both the first clamping ring and the second clamping ring have a silicone pad.

[0013] Preferably, a rubber sleeve is provided on the surface of the arc-shaped rod, and the rubber sleeve has anti-slip grooves.

[0014] The utility model has the following beneficial effects:

[0015] 1. The present invention adopts a structural design of positioning holes, connecting rods, fixing rods, curved rods and positioning pins. When unloading is required after processing is completed, the positioning pins are inserted into the positioning holes after pulling the curved rods, and the positions of all the first clamping rings on the base plate can be changed at the same time, so that the first clamping rings no longer contact the lenses placed in the mounting rings. Therefore, the lenses in the mounting rings can be quickly taken out to complete unloading. Compared with the existing unloading method, the present device has higher unloading efficiency and lower work intensity when in use.

[0016] 2. The structural design of the slide groove, slider and protrusion of the utility model can support and lift the horizontal movement of the fixed rod when operating the arc rod, thereby ensuring the stability of the unloading operation process and extending its service life.

[0024] There are two slide grooves 101 on the top of the base plate 1. Slide blocks 102 are slidably fitted in the two slide grooves 101. A protrusion 103 is provided on the top of the slider 102. The top of the protrusion 103 is fixedly connected to the bottom of the fixed rod 4. There are several protrusions 103.

[0025] Several first clamping rings 201 are symmetrically provided with connecting rods 3 with the circle of the mounting ring 2 as the midpoint. The shape of the connecting rod 3 is an inverted "U" shape. The bottoms of several connecting rods 3 located on the same side are fixedly connected to fixing rods 4. There are two fixing rods 4, and the two fixing rods 4 are fixedly connected to arc rods 5.

[0026] In this embodiment, the glass lens to be processed is placed in the mounting ring 2, and the glass lens is adaptively clamped and positioned by the first clamping ring 201 and the second clamping ring 202. After the processing is completed, the staff pulls the arc rod 5, and the movement of the arc rod 5 to one side will drive the two fixed rods 4 to move synchronously. At the same time, under the action of the protrusion 103, the slider 102 slides in the slide groove 101, and the movement of the two fixed rods 4 causes the connecting rod 3 on each mounting ring 2 to move synchronously to one side, thereby causing all the first clamping rings 201 to move synchronously, so that the first clamping ring 201 no longer contacts the lens placed in the mounting ring 2, so that the lens in the mounting ring 2 can be quickly taken out to complete the unloading. Compared with the existing unloading method, the present device has higher unloading efficiency and lower work intensity when in use.

[0027] In this embodiment, Figure 1 、 Figure 2 and Figure 4 As shown, a positioning hole 104 is opened on the bottom plate 1, an arc-shaped protrusion is provided on the arc-shaped rod 5, a through-hole is provided on the arc-shaped protrusion, a positioning pin 6 is fitted in the through-hole, and the positioning pin 6 is fitted in the positioning hole 104.

[0028] In this embodiment, after moving the arc rod 5, the positioning pin 6 can be used to penetrate the through hole and insert the positioning pin 6 into the positioning hole 104 to complete the positioning of the arc rod 5. At this time, the staff can use both hands to unload the lens, further improving the unloading speed.

[0029] In this embodiment, the positioning pin 6 may be a hand screw, and the positioning hole 104 may be a threaded hole that cooperates with the hand screw.

[0030] In this embodiment, Figure 1 and Figure 3 As shown, a circular cavity is opened on the inner wall of the mounting ring 2, a spring is arranged in the circular cavity, one end of the spring is fixed to the cylinder, the cylinder and the circular cavity are gap-fitted, and the end of the cylinder away from the spring is fixed to the first clamping ring 201.

[0031] In this embodiment, the glass lens is placed in the mounting ring 2 , and under the action of the spring, the glass lens can be adaptively clamped and fixed by the first clamping ring 201 and the second clamping ring 202 .

[0032] In this embodiment, Figure 1 and Figure 3 As shown, the first clamping ring 201 and the second clamping ring 202 have the same structure, and both the first clamping ring 201 and the second clamping ring 202 have a silicone pad.

[0033] In this embodiment, the provision of a silicone pad can prevent the glass lens from being worn when being clamped.

[0034] In this embodiment, Figure 1 and Figure 4 As shown, the surface of the arc rod 5 is provided with a rubber sleeve, and the rubber sleeve has anti-slip grooves.

[0035] In this embodiment, the provision of the rubber sleeve can increase the friction with the worker's hand, thereby achieving the benefit of easy operation.

[0036] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this.
