Description

Technical Field

[0001] This utility model relates to the field of waveplate processing clamping technology, specifically a multi-station clamping device for waveplate processing. Background Technology

[0002] A waveplate is an optical phase delay device based on a birefringent crystal. It introduces a specific phase difference between two beams by decomposing the incident light into ordinary and extraordinary beams with mutually perpendicular vibration directions and generating different propagation speeds within the crystal. The true zero-order waveplate is a high-precision phase delay device. Its core design uses two extremely thin birefringent crystals bonded together with their fast axes orthogonal. Zero-order delay is achieved through physical thickness compensation rather than multi-order interference effects.

[0003] The following problems still exist when clamping and processing existing true zero-order waveplates:

[0004] When clamping waveplates, processing is generally carried out through multi-station clamping. However, the position and angle during processing are relatively simple and cannot be synchronously changed according to actual needs. This reduces the processing efficiency of waveplates in practice and cannot reduce the complexity of operation when synchronizing angle and position changes, thus increasing the maintenance cost in reality.

[0005] Therefore, this utility model introduces a multi-station clamping device for wave plate processing. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a multi-station clamping device for waveplate processing, which has the advantages of simultaneously rotating the clamped waveplate and synchronously changing its position, thus solving the problems mentioned in the background technology.

[0007] This utility model provides the following technical solution: a multi-station clamping device for waveplate processing, including a clamping table and a rotating plate. The upper surface of the clamping table is provided with an adjusting rotation mechanism, which includes a sliding plate, a receiving frame, a gear ring, a support frame, and a fixing bar. A sliding groove is opened inside the clamping table. The outer surface of the sliding plate is slidably connected to the inner wall of the sliding groove. The bottom of the receiving frame is fixedly installed to the top of the sliding plate. The bottom of the rotating plate is rotatably connected to the top of the receiving frame. The inner ring of the gear ring is fixedly installed to the outer surface of the rotating plate. The bottom of the support frame is fixedly connected to the left side of the upper surface of the clamping table. The bottom of the fixing bar is fixedly installed to the top of the support frame. The right side of the fixing bar meshes with the outer surface of the gear ring.

[0008] Preferably, the upper surface of the rotating plate is provided with a limiting mechanism, which includes a fixing block, an extension block, a screw, a turning block, and a limiting block. The lower surface of the fixing block is fixedly connected to the upper surface of the rotating plate, the back side of the extension block is fixedly connected to the front side of the movable rod, the outer surface of the screw is threadedly connected to the inner wall of the extension block, the back side of the turning block is fixedly installed to one end of the screw, and the front side of the limiting block is fixedly installed to the other end of the screw.

[0009] Preferably, a fixing plate is fixedly installed on the front of the clamping platform, and a hydraulic push rod is fixedly installed on the front of the fixing plate.

[0010] Preferably, the output shaft of the hydraulic push rod is fixedly connected to the front side of the sliding plate.

[0011] Preferably, a limiting slide rod is fixedly installed on the inner wall of the sliding groove, and the outer surface of the limiting slide rod is slidably connected to the inner wall of the sliding plate.

[0012] Preferably, a movable rod is slidably connected to the inner wall of the fixed block, a clamping plate is fixedly installed at one end of the movable rod, and the outer surface of the movable rod abuts against the back of the limiting block.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This multi-station clamping device for waveplate processing uses a hydraulic push rod to drive the sliding plate to move horizontally. Simultaneously, a gear ring meshes with a fixed bar, causing the rotating plate to rotate synchronously during translation. This enables rapid multi-angle positioning during waveplate processing, improving processing efficiency. A limiting slide rod ensures smooth sliding plate movement and prevents deviation, while the gear meshing structure ensures precise rotation of the rotating plate, keeping the waveplate stable during processing and improving accuracy. This solves the problem of how to rotate and change the position of the clamped waveplate, achieving a more comprehensive waveplate processing effect and reducing operational complexity, thus facilitating more efficient use in practice.

[0015] 2. This multi-station clamping device for corrugated plate processing, through a screw mechanism with threaded drive, allows operators to precisely control the contact force of the limiting block against the movable rod, achieving flexible clamping of corrugated plates of different sizes. This avoids workpiece damage that may be caused by traditional rigid clamps. The design of the screwing block facilitates manual operation, and the sliding connection structure of the movable rod enables rapid positioning of the clamping plate while ensuring stable clamping during processing through the screw's self-locking characteristic. This solves the problem of how to further ensure the positional stability of the clamped corrugated plate, achieving a more efficient effect when limiting corrugated plates, facilitating more stable use in practice, and promoting its widespread application.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 and Figure 3 A multi-station clamping device for waveplate processing includes a clamping table 1 and a rotating plate 7. An adjusting rotation mechanism is provided on the upper surface of the clamping table 1. The adjusting rotation mechanism includes a sliding plate 5, a receiving frame 6, a gear ring 8, a support frame 9, and a fixing bar 10. A sliding groove 2 is formed inside the clamping table 1. The outer surface of the sliding plate 5 is slidably connected to the inner wall of the sliding groove 2. The bottom of the receiving frame 6 is fixedly installed to the top of the sliding plate 5. The bottom of the rotating plate 7 is rotatably connected to the top of the receiving frame 6. The inner ring of the gear ring 8 is connected to the outer ring of the rotating plate 7. The support frame 9 is fixedly connected to the left side of the upper surface of the clamping table 1. The bottom of the fixing strip 10 is fixedly connected to the top of the support frame 9. The right side of the fixing strip 10 meshes with the outer surface of the gear ring 8. The front of the clamping table 1 is fixedly installed with a fixing plate 3. The front of the fixing plate 3 is fixedly installed with a hydraulic push rod 4. The output shaft of the hydraulic push rod 4 is fixedly connected to the front of the sliding plate 5. The inner wall of the sliding groove 2 is fixedly installed with a limiting slide rod 18. The outer surface of the limiting slide rod 18 is slidably connected to the inner wall of the sliding plate 5.

[0023] Specifically, the sliding plate 5 slides within the sliding groove 2, and its inner wall is slidably connected to the limiting slide rod 18. This design not only enhances the stability of the sliding plate 5's movement but also further restricts the direction of movement of the sliding plate 5 through the limiting slide rod 18, preventing it from deviating and improving the reliability of the clamping device. When the rotating plate 7 needs to rotate, precise angle adjustment can be achieved through the meshing action of the gear ring 8 and the fixing strip 10, improving the flexibility and accuracy of the clamping device. The rotating plate 7 can rotate freely on the receiving frame 6, while the receiving frame 6 moves together with the sliding plate 5, achieving the effect of adjusting the rotation position.

[0024] Please see Figure 2 and Figure 4 The upper surface of the rotating plate 7 is provided with a limiting mechanism, which includes a fixed block 11, an extension block 14, a screw 15, a screwing block 16, and a limiting block 17. The lower surface of the fixed block 11 is fixedly connected to the upper surface of the rotating plate 7. The back side of the extension block 14 is fixedly connected to the front side of the movable rod 12. The outer surface of the screw 15 is threadedly connected to the inner wall of the extension block 14. The back side of the screwing block 16 is fixedly installed to one end of the screw 15. The front side of the limiting block 17 is fixedly installed to the other end of the screw 15. The movable rod 12 is slidably connected to the inner wall of the fixed block 11. A clamping plate 13 is fixedly installed at one end of the movable rod 12. The outer surface of the movable rod 12 abuts against the back side of the limiting block 17.

[0025] Specifically, the movable rod 12 slides on the inner wall of the fixed block 11, allowing the clamping plate 13 to be adjusted in position as needed to accommodate waveplates of different sizes, thus improving the versatility of the clamping device. The limiting block 17 can be adjusted in position as needed to limit the movement range of the movable rod 12, preventing the clamping plate 13 from moving excessively or clamping too tightly, protecting the waveplate from damage. When the movable rod 12 moves to a certain position, the limiting block 17 will prevent it from moving further, thereby ensuring the clamping force and positional accuracy of the clamping plate 13.

[0026] Working principle: When using the waveplate, the movable rod 12 slides on the inner wall of the fixed block 11 to allow one side of the clamping plate 13 to abut against the outer surface of the waveplate. Then, by rotating the screw block 16, the screw 15 drives the limiting block 17 to press against the movable rod 12, so that the clamping plate 13 radially clamps and fixes the waveplate, which can be more stable when limiting the waveplate. After that, the hydraulic push rod 4 pushes the sliding plate 5 to move horizontally in the sliding groove 2. The power source of the hydraulic push rod 4 mainly relies on the interaction of the closed high-pressure gas nitrogen and hydraulic oil inside it. It can achieve self-drive without external power input, which can drive the support frame 6 and the rotating plate 7 to move as a whole. At the same time, the gear ring 8 meshes with the fixed bar 10 to drive the rotating plate 7 to rotate synchronously during the movement, realizing the rotation and displacement change of the clamped waveplate.

[0027] It should be noted that the electrical components and equipment mentioned above all use external power sources. The circuits, electronic components, and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art and need not be elaborated upon.
