Description

Technical Field

[0001] This utility model relates to the field of lens processing technology, specifically a fixing device for processing faceted lenses. Background Technology

[0002] A faceted lens is a lens with a specific facet or geometry that can alter the path of light or produce specific optical effects. The manufacturing process of a faceted lens is similar to that of a conventional lens, but it also includes additional cutting and grinding steps to create the desired facet.

[0003] In the processing of faceted lenses, the material needs to be fixed. However, considering that the existing technology makes it inconvenient to fix the lens material as a whole, resulting in too few stress points, which affects the stability and quality of the material, it is extremely inconvenient. Utility model CN222449955U proposes a fixing device for faceted lens processing, solving the problem of the inconvenience of fixing the lens material as a whole in the existing technology, resulting in too few stress points, affecting the stability and quality of the material. A fixing device for faceted lens processing includes a frame, with a bidirectional screw rotatably connected to the inner side of the frame, and a drive motor fixedly connected to one side of the outer wall of the frame by bolts. Both ends of the bidirectional screw are threadedly connected to nut seats, and a fixing plate is fixedly connected to one side of each of the two nut seats. A telescopic rod is fixedly connected to one side of each of the two fixing plates. The method proposed in this utility model uses two soft pads close to each other to clamp the side of the material, and then uses a bearing plate to support the material, which can clamp the material at multiple points and has high practicality.

[0004] However, the above-mentioned existing technology still has shortcomings in use: the faceted lens needs to be fixed before it can be easily processed by external cutting, grinding or polishing equipment. However, after the faceted lens is fixed, it does not have the function of rotation and translation, which makes it inconvenient to reposition, grind, cut or polish the faceted lens. For example, after processing one side of the faceted lens, it is necessary to disassemble and clean it and adjust the other side to match the processing equipment, thus affecting the processing efficiency.

[0005] Therefore, this utility model provides a fixing device for processing faceted lenses. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a fixing device for processing faceted lenses, so as to solve the problems mentioned in the background art. The fixing structure of this utility model can control the rotation and movement of the faceted lens after fixing it, and the external processing equipment can process it in different positions.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a fixing device for processing faceted lenses, comprising a fixed base, a support plate on the top of the fixed base, a guide sleeve fixedly mounted on the top of the support plate, an upper slide plate and a lower slide plate fitted inside the guide sleeve, a right support plate and a left support plate fixedly connected to one adjacent end of the upper slide plate and the lower slide plate respectively, a coaxial rotating shaft on the opposite side of the right support plate and the left support plate, a clamping plate fixedly connected to one end of the rotating shaft between the right support plate and the left support plate, and a control component for controlling the upper slide plate and the lower slide plate to slide in opposite directions inside the guide sleeve.

[0008] Furthermore, the control component includes a gear and a toothed plate. Positioning grooves are provided on opposite sides of the upper and lower sliding plates. A toothed plate is fixedly connected in the positioning groove. The gear is rotatably connected in the guide sleeve and meshes with the toothed plates on the upper and lower sliding plates.

[0009] Furthermore, a wheel axle is fixedly provided in the middle of the gear, passing through the guide sleeve, and an output shaft and an adjusting motor fixedly connected to one end of the wheel axle are fixedly connected to one side of the guide sleeve.

[0010] Furthermore, one end of the guide sleeve is fixedly connected to a support plate located below the lower slide plate, and the bottom of the support plate is fixedly connected to an electric telescopic rod. The output shaft end of the electric telescopic rod passes through the lower slide plate and is fixedly connected to a limiting plate located between the right support plate and the left support plate.

[0011] Furthermore, a bottom protective pad is adhered to the upper surface of the limiting plate.

[0012] Furthermore, a side protective pad is adhered to one side of the clamp.

[0013] Furthermore, a slider is fixedly connected to the bottom of the support plate, and a sliding groove is provided on the upper end face of the fixed base to slide and cooperate with the slider. Positioning plates located at both ends of the support plate are fixedly connected to the upper end face of the fixed base, and a lead screw is screwed through the support plate and its two ends are respectively rotatably connected to the positioning plates.

[0014] Furthermore, one side of the right support plate is fixedly connected to an output shaft and a control motor fixedly connected to one end of an adjacent rotating shaft.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. In this utility model, a rotating shaft is set on the opposite side of the left and right support plates, and a clamping plate is fixedly connected to one end of the rotating shaft. After the clamping plate clamps the lens, the lens can be driven to rotate by controlling one of the rotating shafts. Compared with the prior art, this has the advantage of quickly switching processing positions.

[0017] 2. In this utility model, a slider is fixedly installed at the bottom of the support plate, and a sliding groove that slides and cooperates with the slider is opened at the top of the fixed base, so that the support plate can move laterally relative to the fixed base, thereby driving the clamped lens to adjust its position laterally. This arrangement facilitates the displacement processing of the clamped lens, thereby improving the efficiency of lens processing. Attached Figure Description

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figures 1 to 3This utility model provides a technical solution: a fixing device for processing faceted lenses, including a fixed base 1, a support plate 2 on the top of the fixed base 1, a guide sleeve 3 fixedly mounted on the top of the support plate 2, an upper slide plate 4 and a lower slide plate 5 fitted inside the guide sleeve 3, the upper slide plate 4 and the lower slide plate 5 being able to slide laterally along the guide sleeve 3, a right support plate 6 and a left support plate 7 respectively fixedly connected to one adjacent end of the upper slide plate 4 and the lower slide plate 5, the right support plate 6 and the left support plate 7 being located on top of the upper slide plate 4 and the lower slide plate 5 respectively. A coaxial rotating shaft 8 is provided on the opposite side of the right support plate 6 and the left support plate 7, one end of the rotating shaft 8 being fixedly connected to a clamping plate 9 located between the right support plate 6 and the left support plate 7, the right support plate 6 and the left support plate 7 moving in opposite directions can drive their respective clamping plates 9 to clamp the faceted lens. In use, a side protective rubber pad 91 is adhered to one side of the clamping plate 9, the side protective rubber pad 91 serving to prevent damage to the faceted lens. The upper sliding plate 4 and the lower sliding plate 5 are designed to keep the cut-face lens in a suspended and clamped state. The advantage of suspension and clamping is that it reduces the potential for interference around the lens.

[0024] The guide sleeve 3 is equipped with a control component 101 for controlling the upper slide plate 4 and the lower slide plate 5 to slide in different directions.

[0025] Specifically, the control component 101 includes a gear 1011 and a toothed plate 1012. Positioning grooves 102 are provided on opposite sides of the upper slide plate 4 and the lower slide plate 5. The toothed plate 1012 is fixedly connected in the positioning groove 102. The gear 1011 is rotatably connected in the guide sleeve 3 and meshes with the toothed plate 1012 on the upper slide plate 4 and the lower slide plate 5. When the gear 1011 rotates, it can drive the upper slide plate 4 and the lower slide plate 5 to move alternately through the toothed plates 1012 on its upper and lower sides, thereby controlling the clamping plate 9 to clamp the cut-face lens.

[0026] The rotatable structure of the rotating shaft 8 allows the faceted lens clamped by the clamping plate 9 to rotate, facilitating different processing positions for external processing equipment. A control motor 105, with an output shaft fixedly connected to one side of the right support plate 6 and one end fixedly connected to the adjacent rotating shaft 8, provides driving force for the rotation of the rotating shaft 8. In use, the control motor 105 is connected to a suitable programmable controller, which controls the number of rotations of the control motor 105. It should be noted that when the lens is subjected to increased processing forces (such as cutting) during processing, a control motor 105 can also be installed on one side of the left support plate 7, thereby facilitating the locking of the rotating shaft 8 by braking the control motor 105.

[0027] In this embodiment, a wheel axle 10111 is fixedly provided in the middle of the gear 1011, which passes through the guide sleeve 3. Connection holes for connecting the wheel axle 10111 to the guide sleeve 3 via bearings can be opened on both sides of the guide sleeve 3. An output shaft is fixedly connected to one side of the guide sleeve 3, and an adjustment motor 106 is fixedly connected to one end of the wheel axle 10111. The adjustment motor 106 provides driving force to the rotation of the wheel axle 10111. In use, the adjustment motor 106 is electrically connected to a programmable controller, which is used to control the number of rotations of the wheel axle 10111.

[0028] In this embodiment, one end of the guide sleeve 3 is fixedly connected to a support plate 31 located below the sliding plate 5. The support plate 31 is parallel to the sliding plate 5. An electric telescopic rod 103 is fixedly connected to the bottom of the support plate 31. The output shaft end of the electric telescopic rod 103 passes through the sliding plate 5 and is fixedly connected to a limiting plate 104 located between the right support plate 6 and the left support plate 7. Specifically, an oblong hole that matches the output shaft clearance of the electric telescopic rod 103 can be opened in the sliding plate 5. The electric telescopic rod 103 is electrically connected to an external programmable controller. The electric telescopic rod 103 provides driving force for the up and down movement of the limiting plate 104. The limiting plate 104, together with the clamping plate 9, further improves the stability of the lens clamping. A bottom protective rubber pad 1041 is adhered to the upper end surface of the limiting plate 104. The bottom protective rubber pad 1041 serves to protect the lens that is limited.

[0029] In this embodiment, a slider 21 is fixedly connected to the bottom of the support plate 2. A groove 11 that slides and engages with the slider 21 is provided on the upper surface of the fixed base 1. Positioning plates 12 located at both ends of the support plate 2 are fixedly connected to the upper surface of the fixed base 1. A lead screw 107 with both ends rotatably connected to the positioning plates 12 is threaded through the support plate 2. Specifically, a threaded hole that engages with the lead screw 107 can be machined through the support plate 2. When the lead screw 107 rotates, it can drive the support plate 2 to translate relative to the fixed base 1, thereby adjusting the position of the lens and facilitating the processing equipment at different positions. In use, an adjustment motor can be fixedly installed on one side of one of the positioning plates 12, and the adjustment motor provides driving force for the rotation of the lead screw 107.

[0030] Working principle: When a lens needs to be clamped, the control gear 1011 rotates, causing the upper slide plate 4 and lower slide plate 5 to drive the right support plate 6 and left support plate 7 to move in opposite directions. Then, the lens is placed between the two clamping plates 9, and the control gear 1011 rotates in the opposite direction, clamping the lens between the two clamping plates 9. At this time, the lens is clamped, and external equipment can process one side of the clamped lens. When it is necessary to switch the processing position, the control motor 105 is started to drive the rotating shaft 8 to rotate. At this time, the lens will rotate, transferring other positions to be processed to the position opposite to the processing equipment. Then, the machining equipment can be controlled to process the lens.

[0031] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
