Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of optical coating processing, in particular to a clamp used for optical coating. Background Art
[0002] Optical coating refers to the process of applying one or more layers of metal or dielectric thin films to the surface of optical components. The purpose of coating optical components is to reduce or increase light reflection, beam splitting, color separation, filtering, and polarization. Common coating methods include vacuum coating and chemical coating. During the coating process, optical components require fixtures to secure them.
[0003] In current optical coating machines, each size of fixture generally requires a matching fixture. This is acceptable for batch-produced small-scale coating components, but for large-scale coating components, the fixture manufacturing cost is high and the number of components is mostly single or several pieces. Therefore, it is too expensive to separately match each component with a tooling fixture, which is not conducive to workers' operation and has low efficiency. Utility Model Content
[0004] The purpose of the utility model is to overcome the deficiencies in the prior art and to provide a fixture for optical coating that can adapt to optical elements of any size and structure and has an excellent fixing effect.
[0005] The present invention achieves the above-mentioned purpose through the following technical solutions: a fixture for optical coating is provided, comprising a coating plate, a mounting cavity is provided in the coating plate, a plurality of clamping components are installed on the coating plate, the clamping component comprises a clamping block slidably installed on the top of the coating plate, a slanted top block is obliquely inserted into the clamping block, the slanted top block extends through the mounting cavity, a mounting seat is provided in the mounting cavity, and slanted top seats corresponding to the number of the slanted top blocks are installed on the mounting seat, the bottom of the slanted top block is installed on the top of the slanted top seat, an electric telescopic cylinder is installed at the bottom of the coating plate, and the telescopic rod of the electric telescopic cylinder is fixedly connected to the mounting seat.
[0006] Furthermore, four clamping assemblies are installed at equal angles on the coating plate.
[0007] Furthermore, four rectangular slots are provided on the top of the coating tray, and the clamping blocks are slidably mounted in the slots.
[0008] Furthermore, a spring is installed between one end of the clamping block close to the center of the coating disk and the inner wall of the slot.
[0009] Furthermore, a bayonet is provided on the top of the inclined ejector seat, a roller member is rotatably installed in the bayonet, and a roller shaft of the roller member is rotatably inserted into the bottom of the inclined ejector block.
[0010] Furthermore, two guide posts are fixedly connected to the inner top of the installation cavity, and the guide posts pass through the installation seat.
[0011] Furthermore, the bottom of the mounting seat locks the inclined top seat on the mounting seat through an inverted screw.
[0012] Furthermore, the head of each clamping block is provided with a clamping pad made of rubber material.
[0013] Compared with the prior art, the beneficial effects of the present invention are:
[0014] 1. By using the combination of the inclined ejector block and the inclined ejector seat, the clamping force can be accurately controlled by adjusting the extension and contraction of the electric telescopic cylinder. By adjusting the position of the inclined ejector block, it can adapt to coated workpieces of different sizes and shapes, increasing the versatility and flexibility of the fixture, reducing the time for replacing and adjusting the fixture, reducing costs and improving work efficiency.
[0015] 2. A spring is installed between one end of the clamping block near the center of the coating disk and the inner wall of the slot to provide a certain buffering effect, preventing the clamping block from exerting excessive pressure on the workpiece during the clamping process and protecting the workpiece from damage.
[0016] 3. The two guide posts fixed at the top of the mounting cavity pass through the mounting base and serve as a guide to ensure that the mounting base remains stable when moving up and down, preventing the mounting base from tilting or offsetting, thereby ensuring the working accuracy of the clamping assembly.
[0017] 4. The head of each clamping block is equipped with a rubber clamping pad, which can increase the friction between the clamping block and the workpiece, preventing the workpiece from sliding during the clamping process. At the same time, the softness of the rubber material can also avoid scratching the surface of the workpiece. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0024] In the description of the present invention, it should be understood that the terms "longitudinal", "transverse", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.
[0025] Combine Figures 1 to 4 The clamp shown in the figure comprises a coating plate 1, which is characterized in that: a mounting cavity 2 is opened in the coating plate 1, and a plurality of clamping assemblies 3 are installed on the coating plate 1, and the clamping assembly 3 comprises a clamping block 4 slidably mounted on the top of the coating plate 1, and an inclined lift block 5 is obliquely inserted into the clamping block 4, and the inclined lift block 5 extends through the mounting cavity 2, and a mounting seat 6 is provided in the mounting cavity 2, and an inclined lift seat 7 corresponding to the number of the inclined lift blocks 5 is installed on the mounting seat 6, and the bottom of the inclined lift block 5 is mounted on the top of the inclined lift seat 7, and an electric telescopic cylinder 8 is installed at the bottom of the coating plate 1, and the telescopic rod of the electric telescopic cylinder 8 is fixedly connected to the mounting seat 6, and four clamping assemblies 3 are installed at equal angles on the coating plate 1; when in use, the electric telescopic cylinder 8 pushes the mounting seat 6 upward, thereby driving the inclined lift seat 7 to push the inclined lift block 5 to move upward, and the inclined lift block 5 inserted in the clamping block 4 and with an inclined design pushes the multiple clamping blocks 4 to move toward the center of the coating plate 1 as it moves upward, thereby clamping the optical coating workpiece;
[0026] The top of the coating plate 1 is provided with four rectangular slots 9, into which the clamping blocks 4 are slidably mounted. The length of the slots 9 is greater than that of the clamping blocks 4. A spring 10 is installed between one end of the clamping block 4 near the center of the coating plate 1 and the inner wall of the slot 9. Figure 2-4 As shown, when in use, the two sides of the bottom of the clamping block 4 are provided with step-shaped clamping blocks, which are slidably mounted in the clamping groove 9 to move. The spring 10 provided provides a certain buffering effect for the movement and clamping of the clamping block 4, preventing the clamping block 4 from causing excessive pressure on the workpiece during the clamping process, thereby protecting the workpiece from damage.
[0027] The top of the inclined top seat 7 is provided with a bayonet hole 71, and a roller member 72 is rotatably installed in the bayonet hole 71, and the roller shaft of the roller member 72 is rotatably inserted into the bottom of the inclined top block 5; when in use, when the mounting seat 6 is pushed upward, the inclined top seat 7 and the inclined top block 5 are driven to move upward together, and since the inclined top block 5 is inclined, the bottom of the inclined top block 5 will move when it moves upward. For this reason, the bottom of the inclined top block 5 is connected to the inclined top seat 7 in a rolling manner, so that the inclined top block 5 can move upward smoothly; the inclined top seat 7 is installed on the mounting seat 6, and the roller member 72 is blocked by the inner walls on both sides when rolling at the through bayonet hole 71, thereby ensuring that it will not roll out; in addition, the bottom of the mounting seat 6 is locked to the mounting seat 6 by the inverted screws, thereby ensuring that the inclined top seat 7 will not shake;
[0028] Two guide posts 11 are fixedly connected to the inner top of the mounting cavity 2 and pass through the mounting seat 6. The guide posts 11 play a guiding role, ensuring that the mounting seat remains stable when moving up and down, preventing the mounting seat from tilting or deflecting, thereby ensuring the working accuracy of the clamping assembly.
[0029] The head of each clamping block 4 is equipped with a clamping pad 12 made of rubber material to increase the friction between the clamping block and the workpiece, preventing the workpiece from sliding during the clamping process. At the same time, the softness of the rubber material can also avoid scratching the surface of the workpiece.
[0030] Working principle: Place the optically coated workpiece in the center of the coating disk 1, then start the electric telescopic cylinder 8, the telescopic rod will lift the mounting seat 6 upward, thereby driving the inclined top seat 7 to push the four inclined top blocks 5 to move upward, the two guide columns 11 serve as a guide for the mounting seat 6, and the inclined top block 5 inserted in the clamping block 4 and with an inclined design will push the four clamping blocks 4 to move toward the center of the coating disk 1 as it moves upward, and at this time, the bottom of the inclined top block 5 also moves in the bayonet 71 through the roller part 72, so that the four clamping blocks 4 have a clamping effect on the optically coated workpiece.
