[0002] CNC machine tools, short for numerical control machine tools, are automated machine tools equipped with a program control system. CNC machine tools effectively solve the problems of machining complex, precise, small-batch, and multi-variety parts. They are flexible, high-efficiency automated machine tools, representing the development direction of modern machine tool control technology, and are a typical mechatronics product.

[0003] In most cases, the board needs to be processed on both sides. However, the traditional method requires the board to be flipped over manually and then put back into the machine tool for processing on the other side, which greatly reduces the processing efficiency. Utility Model Content

[0004] To address the issue that in most cases, sheet metal processing requires double-sided processing, and the traditional method necessitates manually flipping the sheet metal before re-entering the machine tool for processing the back side, the purpose of this invention is to provide a multi-angle flipping clamping device for CNC machine tool processing.

[0005] To solve the above technical problems, this utility model adopts the following technical solution: a multi-angle flipping clamping device for CNC machine tool processing, including a machining table, a fixed frame fixedly installed at the top center of the machining table, two symmetrically distributed fixed plates provided at the lower part of the fixed frame, cylinders fixedly installed on the upper parts of the opposite sides of the two fixed plates, toothed plates provided on one side of each of the two cylinders, one end of each of the two toothed plates fixedly installed on the driving end of the cylinder, and limit rods fixedly installed on the upper parts of the opposite sides of the two fixed plates, with one side of each of the two toothed plates slidably locked onto the outer surface of the limit rods.

A clamping device body is fixedly mounted on the lower side of each of the two timing belts. Two symmetrically distributed sliders are fixedly mounted on opposite sides of each of the two fixed plates. A sliding groove is opened in the middle of the opposite side of each fixed frame. The four sliders are slidably locked in the middle of the sliding groove. A drive assembly is provided on the upper side of the fixed frame. A processing device is fixedly mounted in the middle of the fixed frame. A base is fixedly mounted at the four corners of the bottom of the processing table.

[0006] Preferably, a rotating shaft is rotatably mounted on the upper part of the fixing frame, and worm gears are fixedly mounted on both ends of the rotating shaft. Worm wheels are provided on one side of each of the two worm gears, and both worm wheels are meshed with the worm gears. A screw is fixedly mounted on the bottom end of each of the two worm wheels. Four sliders are threaded onto the lower part of the screws. The driving assembly includes a motor, the bottom end of which is fixedly mounted on one side of the upper part of the fixing frame. One end of the rotating shaft is fixedly mounted on the driving end of the motor. A cavity is formed in the upper part of the fixing frame, and the two worm wheels are rotatably mounted on both sides of the cavity.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0008] 1. This application enables convenient and quick flipping of boards, which can significantly improve processing efficiency, reduce manual flipping steps, and achieve continuous operation.

[0009] 2. This application can adjust the height of its clamping device body, thereby moving the height of the plate away from the processing table, which facilitates the flipping of larger and wider plates, making the equipment more practical to use. Attached Figure Description

[0016] 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.

[0017] Example: Figure 1-4 As shown, this utility model provides a multi-angle flipping clamping device for CNC machine tool processing, including a processing table 1. A fixed frame 2 is fixedly installed at the top center of the processing table 1. Two symmetrically distributed fixed plates 4 are provided at the lower part of the fixed frame 2. Cylinders 41 are fixedly installed on the upper part of the opposite sides of the two fixed plates 4. A toothed plate 42 is provided on one side of each of the two cylinders 41. One end of each toothed plate 42 is fixedly installed on the driving end of the cylinder 41. A synchronous belt 45 is rotatably installed in the middle of each of the two fixed plates 4. A gear 44 is fixedly installed on the upper side of each of the two synchronous belts 45. Both gears 44 are meshed with the toothed plates 42. A clamping device body 46 is fixedly installed on the lower side of each of the two synchronous belts 45. Two symmetrically distributed sliders 36 are fixedly installed on the opposite sides of the two fixed plates 4. A drive assembly is provided on the upper side of the fixed frame 2.

[0018] A rotating shaft 31 is rotatably mounted on the upper part of the fixed frame 2. Worms 32 are fixedly mounted on both ends of the rotating shaft 31. Worm wheels 33 are provided on one side of each of the two worms 32. Both worm wheels 33 are meshed with the worms 32. Screws 34 are fixedly mounted on the bottom end of each of the two worm wheels 33. Four sliders 36 are threadedly mounted on the lower part of the screws 34. By setting the worm wheels 33 and worms 32, the structure has a self-locking function, so that after the screws 34 rotate and drive the clamping device body 46 to move upward, it can remain stable and avoid the screws 34 from flipping under the action of gravity, which would cause the plate that needs to be flipped to reset.

[0019] The drive assembly includes a motor 3, the bottom end of which is fixedly mounted on the upper side of the mounting frame 2, and one end of the rotating shaft 31 is fixedly mounted on the drive end of the motor 3. By setting the motor 3, the rotating shaft 31 can be driven to rotate under the drive of the motor 3.

[0020] The upper part of the fixing frame 2 is provided with a cavity 35, and the two worm gears 33 are rotatably installed on both sides of the cavity 35. By setting the cavity 35, the worm gears 33 and the worm 32 can be conveniently installed and used.

[0021] The fixing frame 2 has a sliding groove 361 in the middle of the opposite side. The four sliders 36 are slidably locked in the middle of the sliding groove 361. By setting the sliding groove 361, the sliders 36 can be moved up and down stably when the screw 34 rotates under the limitation of the sliding groove 361.

[0022] The processing equipment 21 is fixedly installed in the middle of the fixed frame 2. By setting the processing equipment 21, the plate material that is clamped and fixed by the clamping device body 46 at its lower part can be processed.

[0023] Limiting rods 43 are fixedly installed on the upper part of the opposite sides of the two fixed plates 4. One side of the two toothed plates 42 is slidably locked on the outer surface of the limiting rods 43. By setting the limiting rods 43, the toothed plates 42 can be limited and supported, so that the toothed plates 42 can drive the gears 44 to rotate more stably when moving.

[0024] The processing table 1 is fixedly installed at the four corners of its bottom end with a base 11. By setting the base 11, the base 11 has a shock absorption effect, so that the whole device avoids shaking during operation.

[0025] Working principle: In actual use, when it is necessary to reverse the processing plate, the cylinder 41 can be started. Under the drive of the cylinder 41, the toothed plate 42 is moved, which in turn drives the meshing gear 44 to rotate, that is, drives the synchronous belt 45 to rotate. Thus, under the transmission of the synchronous belt 45, the clamping device body 46 is rotated, that is, the clamped plate is flipped.

[0026] When flipping large and wide objects, the motor 3 drives the rotating shaft 31 to rotate, which in turn drives the worm gear 32 to rotate, which in turn drives the worm wheel 33 to rotate. This causes the two screws 34 to rotate simultaneously, which in turn drives the slider 36 to move. This, in turn, causes the clamping device body 46 and the clamped plate to move upwards simultaneously, thus moving the plate away from the surface of the processing table 1. Under the drive of the cylinder 41, the plate can be flipped. After the flipping is completed, the motor 3 rotates in the opposite direction to restore it to its original height.

[0027] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
