The following describes the embodiments of the present invention based on its overall structure.
[0022] Reference Figures 1 to 5 In the embodiment of the utility model, a hydraulic jig unloading device for a CNC machine tool includes: a jig base 1, a jig platform 2 is fixedly arranged at one end above the jig base 1, a slide rail 3 is fixedly arranged at the other end above the jig base 1, an insertion rod 4 is fixedly arranged above the jig platform 2, a workpiece 5 is inserted above the insertion rod 4, a sliding base plate 6 is slidingly arranged above the slide rail 3, an oil hydraulic jack 7 is fixedly arranged above the sliding base plate 6, a support plate 8 is fixedly arranged above the oil hydraulic jack 7, a clamping mechanism support rod 9 is fixedly arranged on the side of the jig base 1, a support rod slide rail 91 is slidingly arranged below the clamping mechanism support rod 9, a clamping mechanism control device 10 is fixedly arranged on one side above the clamping mechanism support rod 9, a movable splint telescopic rod 11 is fixedly connected to the bottom of the clamping mechanism control device 10, a movable splint connecting block 12 is fixedly connected to the bottom of the movable splint telescopic rod 11, and a movable splint connecting block 12 is rotatably connected to the side of the movable splint connecting block 12.
[0023] The above solution is adopted: the clamping mechanism support rod 9 firmly supports the clamping mechanism, and the clamping mechanism control device 10 realizes reliable clamping of the workpiece 5 by precisely controlling the movement of the movable splint telescopic rod 11, the movable splint connecting block 12 and the movable splint 13. This reliability ensures the stability and safety of the workpiece 5 during the processing.
[0024] A material return platform base 14 is fixedly provided on the other side of the jig base 1, a material return platform telescopic rod base 15 is fixedly provided on one end above the material return platform base 14, a material return platform telescopic rod 16 is fixedly provided above the material return platform telescopic rod base 15, a support plate 17 is fixedly provided above the material return platform telescopic rod 16, a material return platform 18 is fixedly provided above the support plate 17, a rotating shaft support rod 19 is fixedly provided on the other end above the material return platform base 14, a rotating shaft support rod 19 is rotatably connected to a rotating shaft 20 on the side of the rotating shaft support rod 19, and the other side of the rotating shaft 20 is rotatably connected to the material return platform 18.
[0025] The above solution is adopted: the support structure composed of the return platform base 14, the return platform telescopic rod base 15, the return platform telescopic rod 16 and the support plate 17 ensures the stability and firmness of the return platform 18. This stable support structure can withstand the weight and impact force of the workpiece 5, ensuring the smooth progress of the return process.
[0026] A receiving platform base 21 is fixedly provided on the other side of the return platform base 14, a receiving platform telescopic rod 22 is fixedly provided above the receiving platform base 21, a receiving platform 23 is provided above the receiving platform telescopic rod 22, a buffer spring rod 24 is fixedly provided on one side of the receiving platform 23, and a buffer plate 25 is fixedly provided on the side of the buffer spring rod 24.
[0027] With the above solution, by providing the receiving platform 23 , the workpiece 5 can directly fall onto the receiving platform after sliding from the unloading platform 18 without manual intervention or additional operation, thereby ensuring the continuity and efficiency of the production process.
[0028] The slide rails 3 are located on both sides of the jig platform 2. There are two groups of sliding base plates 6, hydraulic jacks 7 and support plates 8. The support plates 8 are located on both sides below the workpiece 5 and can lift the workpiece 5 from the insertion rod 4. There are multiple groups of movable splints 13 and can clamp the workpiece 5 from the support plates 8. The clamping mechanism support rod 9, the clamping mechanism control device 10, the movable splint telescopic rod 11, the movable splint connecting block 12 and the movable splint 13 constitute the clamping mechanism, and the clamping mechanism is moved to the top of the material return table 18 through the support rod slide rail 91.
[0029] The above scheme is adopted: there are multiple groups of movable clamps 13, which can ensure that the workpiece 5 is firmly clamped on the support plate 8. The synergistic effect of multiple groups of clamps makes the clamping more uniform and stable, reducing the shaking or displacement of the workpiece 5 during the clamping process. By setting two groups of sliding base plates 6, hydraulic jacks 7 and support plates 8, lifting operations can be performed simultaneously from both sides of the workpiece 5. This not only disperses the lifting force, but also improves the efficiency of material return and reduces the time required for material return.
[0030] There are two sets of telescopic rod base 15, telescopic rod 16 and support plate 17 for the material return platform. The rotating shaft 20 can facilitate the two sets of telescopic rods 16 to adjust different heights so that the material return platform 18 has a certain tilt angle.
[0031] The above solution is adopted: the return platform 18 and the shaft support rod 19 are connected by the shaft 20, and the return platform 18 can be tilted at a certain angle. This design enables the return platform 18 to adapt to the return requirements of different workpieces 5, ensuring that the workpiece 5 can slide smoothly and avoid getting stuck or falling improperly.
[0032] A control device must be provided inside the receiving platform 23. A driving shaft is rotatably provided under the receiving platform 23. The driving shaft is rotatably connected to the receiving platform telescopic rod 22. There are multiple groups of buffer spring rods 24. The buffer plate 25 can buffer and support the workpiece 5 that slides down from the unloading platform 18.
[0033] By adopting the above solution, by introducing the buffer spring rod 24 and the buffer plate 25, when the workpiece 5 falls onto the receiving platform 23, it can be buffered to a certain extent, reducing the possibility of the workpiece 5 bouncing or flying out, thereby improving the safety of the operation.
[0034] The working principle of the present invention is as follows: first, the workpiece 5 is inserted into the insertion rod 4 above the jig platform 2 for processing or positioning to ensure the stability of the workpiece 5 during the processing. When the material needs to be withdrawn, the hydraulic jack 7 slides on the slide rail 3 through the sliding base plate 6 to the bottom of the workpiece 5. The hydraulic jack 7 works to make the support plate 8 rise, lift the workpiece 5, and make it detach from the insertion rod 4. The support plates 8 are located on both sides below the workpiece 5 to ensure that the workpiece 5 is stably lifted. At the same time, the clamping mechanism moves to the top of the support plate 8 on the support rod slide rail 91 through the clamping mechanism support rod 9. The clamping mechanism control device 10 controls the extension and retraction of the movable splint telescopic rod 11, thereby driving the movable splint 13 to clamp the workpiece 5 through the movable splint connecting block 12. There are multiple groups of movable splints 13 to ensure that the workpiece 5 is firmly clamped , then, the clamping mechanism moves together with the workpiece 5 to the top of the unloading platform 18, and the unloading platform telescopic rod base 15 on the unloading platform base 14 controls the height of the support plate 17 and the unloading platform 18 through the unloading platform telescopic rod 16, and the rotating shaft 20 connects the unloading platform 18 and the rotating shaft support rod 19, allowing the inclination angle of the unloading platform 18 to be adjusted so that the workpiece 5 can slide down smoothly, and the clamping mechanism releases the workpiece 5, and the workpiece 5 slides down from the unloading platform 18 under the action of gravity. At this time, the receiving platform 23 is adjusted to a suitable position through the receiving platform telescopic rod 22, and the internal control device controls the rotation of the driving shaft under the receiving platform 23, so that the receiving platform 23 can receive the workpiece 5 that slides down from the unloading platform 18, and the buffer spring rod 24 and the buffer plate 25 are used to buffer the impact of the workpiece 5 and protect the workpiece 5 from damage.
[0035] 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. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
