Description

Technical Field

[0001] This utility model relates to the field of optical glass processing, and in particular to a clamping fixture for cutting optical glass. Background Technology

[0002] Optical glass is glass capable of altering the direction of light propagation and changing the relative spectral distribution of ultraviolet, visible, or infrared light. In a narrow sense, optical glass refers to colorless optical glass; in a broader sense, it also includes colored optical glass, laser glass, quartz optical glass, radiation-resistant glass, ultraviolet-infrared optical glass, fiber optic glass, acousto-optic glass, magneto-optic glass, and photochromic glass. Optical glass is used to manufacture lenses, prisms, mirrors, and windows in optical instruments. Components made of optical glass are key elements in optical instruments.

[0003] Currently, when cutting optical glass, it is necessary to first use corresponding tooling fixtures to fix the glass as a whole. Before fixing, the limiting modules on the tooling fixtures need to be adjusted to secure the glass of the corresponding specifications. However, the adjustment process for existing tooling fixtures is lengthy, consuming processing time and affecting production efficiency. Furthermore, optical glass is difficult to secure reliably with conventional fixing devices, and misalignment during processing can lead to finished optical glass that does not meet production requirements. Secondly, the clamping force of most fixing devices is not adjustable, often causing damage to the brittle optical glass. Therefore, it is necessary to design a quick-clamping tooling for cutting optical glass to solve these problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a clamping fixture for cutting optical glass.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model discloses a clamping fixture for cutting optical glass, comprising a base with four supporting legs; two guide rails fixedly connected to the upper part of the base for horizontally placing an optical glass plate; a front clamping mechanism and a rear clamping mechanism arranged opposite to each other for clamping and fixing the front and rear sides of the optical glass; a left clamping mechanism and a right clamping mechanism arranged opposite to each other for clamping and fixing the left and right sides of the optical glass plate; a front sensing device fixedly connected to the front side of the base for detecting whether the workpiece is clamped in the front-back direction; and a right sensing device fixedly connected to the right side of the base for detecting whether the workpiece is clamped in the left-right direction.

[0007] As a preferred embodiment of this utility model, the two guide rails are placed in parallel, and the guide rails are square in shape.

[0008] As a preferred embodiment of this utility model, the front clamping mechanism, the rear clamping mechanism, the left clamping mechanism, and the right clamping mechanism each include an L-shaped fixed plate fixed below the base, a movable plate opposite to the L-shaped fixed plate, a telescopic cylinder fixed to the side of the L-shaped fixed plate, two guide shafts fixed to one side of the movable plate, and two guide shaft supports coaxially arranged with the guide shafts. Two push plates are arranged parallel to each other on one side of the movable plate, and each push plate has a pressing block on its top.

[0009] As a preferred technical solution of this utility model, a floating joint is provided between the telescopic cylinder and the movable plate, and the two guide shaft supports are fixed to the side of the L-shaped fixed plate.

[0010] As a preferred embodiment of the present invention, both the front clamping mechanism and the right clamping mechanism further include a limiting component for limiting the push plate. The limiting component includes a stop block and an adjustable screw corresponding to the stop block. The stop block is fixed to the side of the movable plate, and the adjustable screw is fixed to the side of the L-shaped fixed plate.

[0011] As a preferred embodiment of the present invention, both the front sensing device and the right sensing device include a sensor and a U-shaped base, with the U-shaped base fixedly connected to the top of the base.

[0012] As a preferred embodiment of this utility model, the clamping block is trapezoidal in shape and is made of polyurethane.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. When using the front, rear, left, and right clamping mechanisms to fix the optical glass plate, the eight clamping blocks can be located around the optical glass and contact its sides, so as to clamp optical glass of different lengths and widths accordingly. Due to the use of the cylinder clamping mechanism and the adjustable screw limiting structure, the fixture can quickly clamp and fix optical glass blanks of different thicknesses and sizes. The clamping and releasing operations are convenient, which solves the problem of low clamping efficiency.

[0015] 2. The clamping force of the cylinder on the glass can be controlled by adjusting the air pressure of the cylinder. The adjustment is simple, avoids the problem of glass damage, and has high practicality.

[0016] 3. A sensing device is used. When the glass is placed in the set position, the sensor transmits a signal to the telescopic cylinder to start the action, realizing the rapid clamping function. Attached Figure Description

[0027] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0028] In the attached diagram, all identical reference numerals refer to the same components.

[0029] like Figure 1-8As shown, this utility model provides a clamping fixture for cutting optical glass, including a base 1 with four supporting feet; two guide rails 2 for horizontally placing optical glass plates; a front clamping mechanism 3, a rear clamping mechanism 4, a left clamping mechanism 5, and a right clamping mechanism 6 for clamping and fixing the sides of the optical glass plates; and a front sensing device 7 and a right sensing device 8 for detecting whether the workpiece is clamped in place. With this design, the optical glass to be processed can be placed on the guide rails 2, and then the telescopic cylinder 11 can move the corresponding two clamping blocks 15 closer or further apart, thereby changing their spacing. This allows the clamping blocks 15 to be positioned around the optical glass and in contact with its sides, achieving the effect of the optical glass sides abutting against the surfaces of the eight clamping blocks 15. The clamping position is adjusted by an adjustable screw limiting structure, thereby completing the fixation of the optical glass for subsequent processing. This fixture can quickly clamp and fix optical glass blanks of different thicknesses and sizes, and the clamping and releasing operations are convenient.

[0030] like Figure 1-2 As shown, in this embodiment, two guide rails 2 are fixed to the top of the base 1 by a threaded connection. The upper surface of the guide rail 2 is in contact with the bottom surface of the glass to be cut, and the glass can slide above the guide rail 2. The front clamping mechanism 3 and the rear clamping mechanism 4 are arranged parallel to each other on the front and rear sides of the base 1 to clamp and fix the optical glass in the front and rear directions. The left clamping mechanism 5 and the right clamping mechanism 6 are arranged opposite to each other on the left and right sides of the base 1 to clamp and fix the optical glass plate in the left and right directions. The push rod of the telescopic cylinder 11 on them drives the push plate 14 and the clamping block 15 to move parallel to the guide rail 2 on the horizontal plane. The front sensing device 7 is fixed to the front side of the base 1 by a threaded connection. The probe direction of its sensor 20 is parallel to the front clamping mechanism 3 to detect whether the workpiece is clamped in the front and rear directions. The right sensing device 8 is fixed to the right side of the base 1 by a threaded connection. The probe direction of its sensor 20 is parallel to the right clamping mechanism 6 to detect whether the workpiece is clamped in the left and right directions.

[0031] The method of using this utility model is as follows:

[0032] 1. Place the optical glass to be processed on the guide rail 2. When both sides of the glass block the sensors 20 of the front and right sensors 8, it indicates that the glass has been placed in the set position. At this time, the sensor 20 sends a signal to the telescopic cylinder 11.

[0033] 2. After receiving the signal, the telescopic cylinder 11 starts to move. Its movable end can bring the corresponding two clamping blocks 15 closer to each other, so that the clamping blocks 15 can be located around the optical glass and in contact with its sides, so that the side of the optical glass abuts against the surface of the eight clamping blocks 15.

[0034] 3. When the telescopic cylinder 11 retracts to the point where the adjustable screw 19 and the stop block 18 are in contact, the cylinder stops moving. At this time, the eight clamping blocks 15 completely press the four sides of the glass together, thus clamping and fixing the optical glass. The optical glass can then proceed to the next cutting process.

[0035] Furthermore, such as Figure 1 As shown, two guide rails 2 are placed in parallel, and the guide rails are square in shape. In this embodiment, the guide rails 2 are arranged along the long side of the glass. The two guide rails 2 are made of stainless steel, and the upper surface of the guide rail 2 that contacts the glass is polished to prevent wear and damage to the surface of the guide rail 2 during the clamping process.

[0036] Furthermore, such as Figure 1-2 The front clamping mechanism 3, rear clamping mechanism 4, left clamping mechanism 5, and right clamping mechanism 6 each include an L-shaped fixed plate 9, a movable plate 10, a telescopic cylinder 11, two guide shafts 12, and two guide shaft supports 13. Two push plates 14 are arranged parallel to each other on one side of the movable plate 10, and each push plate 14 has a pressing block 15 on its top. In this embodiment, the top surface of the L-shaped fixed plate 9 is fixed to the lower surface of the base 1 by a threaded connection; the movable plate 10 is arranged parallel to the L-shaped fixed plate 9, and the telescopic cylinder 11 is fixed to the side of the L-shaped fixed plate 9 by a threaded connection; the tops of the two guide shafts 12 are fixed to the side of the movable plate 10 by bolts, and the guide shafts 12 are arranged parallel to the movable shaft of the telescopic cylinder 11, used to drive the movable plate 10 to move horizontally; the two guide shaft supports 13 are coaxially arranged with the guide shafts 12, and each guide shaft support 13 uses four... Bolts are fixed to the L-shaped fixing plate 9 for limiting the movement of the guide shaft 12; the sides of the two push plates 14 are fixed to the sides of the movable plate 10 by bolts, and the push plates 14 in the front-rear direction and the left-right direction are arranged opposite each other. When the movable plate 10 moves horizontally under the push of the telescopic cylinder, the push plates 14 in the same direction move in the opposite direction or in the same direction as the movable plate 10 to clamp or release the glass; the clamping block 15 is fixed to the top of the push plate 14 by adhesive and is used to contact the side of the glass.

[0037] Furthermore, such as Figure 7-8 As shown, a floating joint 16 is provided between the telescopic cylinder 11 and the movable plate 10. Two guide shaft supports 13 are fixed to the side of the L-shaped fixed plate 9. In this embodiment, the bottom end of the floating joint 16 is fixed to the telescopic end of the telescopic cylinder 11 by a threaded connection. The top end of the floating joint 16 is provided with two locking nuts. The two nuts are located on the two sides of the movable plate 10 respectively, and are used to lock the movable plate 10. The side of the guide shaft support 13 is fixed to the side of the L-shaped fixed plate 9 by a threaded connection.

[0038] Furthermore, such as Figure 5-8As shown, both the front clamping mechanism 3 and the right clamping mechanism 6 further include a limiting component 17 for limiting the push plate 14. The limiting component 17 includes a stop block 18 and an adjustable screw 19 corresponding to the stop block 18. In this embodiment, the bottom of the stop block 18 is fixed to the side of the movable plate 10 by a threaded connection, and the adjustable screw 19 is fixed to the side of the L-shaped fixed plate 9 by a threaded connection. The stop block 18 and the adjustable screw 19 are coaxially arranged. During the telescopic movement of the telescopic cylinder 11, when the top of the adjustable screw 19 contacts the surface of the stop block 18, the push plate 14 stops moving, and the pressing block 15 located on the push plate 14 also stops moving, thus playing a limiting function. Since the adjustable screw 19 can be adjusted by adjusting the length of the thread screw into the L-shaped fixed plate 9, the position of the push plate 14 can be controlled, thereby realizing the clamping of glass of different sizes.

[0039] Furthermore, such as Figure 6 As shown, both the front sensing device 7 and the right sensing device 8 include a sensor 20 and a U-shaped base 21. The U-shaped base 21 is fixed to the top of the base 1. In this embodiment, the sensor 20 is fixed to the inner side of the U-shaped base 21 by a threaded connection and is located at the top of the U-shaped structure. The lower end of the U-shaped base 21 is provided with a round hole and is fixed to the upper surface of the base 1 by a threaded connection. When there is glass blocking the front of the sensor 20, the sensor sends a signal to the telescopic cylinder 11. At this time, the telescopic cylinder 11 starts to move, realizing the function of rapid clamping.

[0040] Furthermore, the clamping block 15 is trapezoidal in shape and made of polyurethane. In this embodiment, the side of the clamping block 15 is trapezoidal, its top end contacts the side of the glass, and its bottom end is fixed to the top of the push plate 14 by a threaded connection. Since polyurethane material has good cushioning performance, it avoids damage to the surface of the glass during the clamping process. In addition, polyurethane material has a certain hardness, which ensures that the glass will not be displaced during the cutting process after clamping the glass, thus increasing the reliability of positioning.

[0041] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
