Description

Technical Field

[0001] The present invention belongs to the technical field of the table surface of a coating machine, and particularly relates to an automatic flipping table surface. Background Art

[0002] The differential pressure coating machine is a special equipment for composite material forming. Its core principle is to use the air pressure difference to make the flexible coating film closely adhere to the surface of the mold, so as to realize the uniform compaction and forming of the composite material blank. This technology is widely used in fields such as aerospace, automobile manufacturing, and wind power blades, especially suitable for the manufacturing of components with complex curved surfaces or large-size structures. At present, the mainstream differential pressure coating machines mainly adopt the methods of vacuum negative pressure or positive pressure pressing. The pressure change in the sealed chamber drives the deformation of the coating film, so that the prepreg or dry fiber blank can fully remove bubbles and be compacted before curing, in order to improve the mechanical properties and surface quality of the workpiece. The differential pressure coating machine usually includes an upper chamber body and a lower chamber body. When coating materials, the upper chamber body is controlled to move by a lift, so that the table surface of the upper chamber body cooperates with the lower chamber body, and then the coating work of the materials is carried out. After the process is completed, it is often necessary to cool the workpiece for a period of time, and then take out the workpiece before processing the next workpiece, resulting in the problem of low processing efficiency.

The middle plate is connected with a displacement driving component, and the displacement driving component can drive the middle chamber body to move up or down; two vertically parallel columns are fixed between the upper plate and the lower plate, and the two columns are symmetrically installed on both sides of the middle plate. A slider is slidably installed on the column, and a rotation driving device is installed between the middle plate and the slider. The rotation driving device is installed in the cavity formed inside the middle plate. The rotation driving device has a horizontal output shaft, and the output shaft is in transmission connection with the slider.

The outer end of the pin is fixedly connected with the limiting plate. An elastic tension spring is connected between the limiting plate and the slider. The elastic tension spring is sleeved on the outer side of the pin. Under the elastic tension of the elastic tension spring, the inner end of the pin abuts against the column.

[0008] Further, the displacement driving assembly includes a first hydraulic cylinder and a second hydraulic cylinder. The first hydraulic cylinder is fixed to the upper plate.

DETAILED DESCRIPTION

[0025] like Figures 1 - 6 As shown, an automatic flip table disclosed in the present invention comprises a middle warehouse body 1, an upper warehouse body 2 and a lower warehouse body 3 respectively located on the upper side and the lower side of the middle warehouse body 1, and a sufficient interval should be left between the upper warehouse body 2 and the lower warehouse body 3 for the middle warehouse body 1 to deflect. The lower end surface of the middle warehouse body 1 forms a working table surface that cooperates with the lower end surface of the upper warehouse body 2 or the upper end surface of the lower warehouse body 3, that is, when the working table surface of the middle warehouse body 1 is downward, the middle warehouse body 1 is controlled to move downward until it contacts with the upper end surface of the lower warehouse body 3, at this time, the middle warehouse body 1 can cooperate with the lower warehouse body 3 to form a completed cavity, which is convenient for draping molding. Similarly, when the working table surface of the middle warehouse body 1 is upward, the middle warehouse body 1 is controlled to move upward until it contacts with the lower end surface of the upper warehouse body 2, and the middle warehouse body 1 can cooperate with the upper warehouse body 2 to form a completed cavity.

[0026] Among them, an upper plate 4 is fixed to the upper end surface of the upper warehouse body 2, a middle plate 5 is fixed to the upper end surface of the middle warehouse body 1, and a lower plate 6 is fixed to the lower end surface of the lower warehouse body 3, so as to be connected and coordinated with the overall structure of the frame. The middle plate 5 is connected to a displacement driving component, which can drive the middle warehouse body 1 to move up or down; two vertical and parallel columns 7 are fixed between the upper plate 4 and the lower plate 6, and the two columns 7 are symmetrically installed on both sides of the middle plate 5. A slider 8 is slidably installed on the column 7, and a rotation driving device 9 is installed between the middle plate 5 and the slider 8.

[0027] The rotation drive device 9 of the present invention adopts a motor with a brake. The rotation drive device 9 is installed in a cavity formed inside the middle plate 5 to avoid interference with the device. The rotation drive device 9 has a horizontal output shaft 10, and the output shaft 10 is transmission-connected to the slider 8. The output shaft 10 is located in the center plane formed by the axes of the two columns 7. An automatic locking member is also installed between the slider 8 and the column 7. The automatic locking member is used to lock the slider 8 to the column 7 after the middle warehouse body 1 is flipped over to prevent the slider 8 from sliding. During operation, the automatic locking member is loosened to avoid interference with the movement of the middle warehouse body 1. Those skilled in the art can understand this.

[0028] In the present invention, by providing a middle bin body 1 that can move up and down and can be flipped, its working surface can cooperate with the upper or lower bin body 3 respectively, realizing the function of switching between double stations or multiple stations. This modular design not only enhances the adaptability of the equipment, enabling it to match the processing requirements of workpieces of different sizes, but also improves production efficiency.

[0029] The working principle and process of the present invention application are as follows:

[0030] 1. Initial positioning stage: The middle bin body 1 is in the initial position, with its lower end face facing the side where the lower bin body 3 is located. At this time, the upper bin body 2 is in the standby state, the slider 8 is positioned by the automatic locking member, and the displacement driving assembly remains in the contracted state. The heater 31 is started to preheat the workpiece to be processed inside the middle bin body 1.

[0031] 2. First station processing stage: The automatic locking member is loosened, the lower bin body 3 is loaded with the coating material, and the displacement driving assembly is started: The first hydraulic cylinder 19 pushes the middle plate 5 downward, and the first end plate 21 driven by the first hydraulic cylinder 19 pushes the piston 24 downward. The hydraulic oil is pressed into the horizontal slide hole 26 through the hydraulic channel 25, and is pushed into the spiral telescopic tube 29 through the hose 28, thereby squeezing the spiral telescopic tube 29. The spiral telescopic tube 29 breaks free from the restraint of the elastic spring 18 and expands, causing the pin 16 to temporarily disengage from the column 7, reducing the frictional resistance; after the lower bin body 3 and the middle bin body 1 are combined, the pressure inside the lower bin body 3 and the middle bin body 1 is changed, and the coating of the lower surface of the workpiece is completed under the action of the pressure difference.

[0032] 3. Flipping stage: The first hydraulic cylinder 19 retracts, the slider 8 is positioned again by the automatic locking member, the rotation driving device 9 is started, and the output shaft 10 drives the middle plate 5 and the middle bin body 1 to flip 180°. After the flipping is completed, the piston 24 faces downward at this time.

[0033] 4. Second station processing stage: After the middle bin body 1 is flipped, the displacement driving assembly acts in the reverse direction, so that the lower end face of the middle bin body 1 is closely fitted with the lower end face of the upper bin body 2 to form a second working surface. The upper bin body 2 is fed with the coating material to complete the processing of the upper surface of the workpiece. If repeated processing is required, it can be flipped again and lowered to the lower bin body 3 station to realize cyclic operation.

[0034] In this embodiment, a notch 11 for installing a slider 8 is formed on the side surface of the middle plate 5. An inner arc surface 12 is formed on the inner side of the notch 11. Outer arc surfaces 13 that cooperate with the inner arc surface 12 are formed on both sides of the slider 8. The outer end of the slider 8 protrudes from the side surface of the middle plate 5. The slider 8 is designed to cooperate with the notch 11 of the middle plate 5 through the inner and outer arc surfaces 13, significantly improving the structural rigidity and torsional resistance during flipping. When the output shaft 10 drives the slider 8 to rotate, the outer arc surface 13 slides along the inner arc surface 12, forming a self-aligning effect and avoiding jamming caused by eccentric loads. Through the cooperation between the slider 8 and the middle plate 5, the force on the output shaft 10 is shared during the displacement process of the middle plate 5.

[0035] In this embodiment, a pin hole 14 is formed on the side surface of the slider 8. The inner end of the pin hole 14 communicates with a guide hole 15 for the cooperation between the slider 8 and the column 7. The automatic locking member includes a pin 16, a limit plate 17, and an elastic spring 18. The inner side of the pin 16 is slidably arranged in the pin hole 14. The outer end of the pin 16 is fixedly connected with the limit plate 17. An elastic spring 18 is connected between the limit plate 17 and the slider 8. The elastic spring 18 is sleeved on the outer side of the pin 16. Under the elastic tension of the elastic spring 18, the inner end of the pin 16 abuts against the column 7. By adopting the above method, the pin 16 can be pressed inward to lock the slider 8. It can be understood that, in order to reduce the damage to the surface of the column 7 caused by the pin 16, a rubber block can be fixed at the inner end of the pin 16, and the friction force can also be increased.

[0036] In this embodiment, the displacement driving assembly includes a first hydraulic cylinder 19 and a second hydraulic cylinder 20. The first hydraulic cylinder 19 is fixed to the upper plate 4. The output end of the first hydraulic cylinder 19 is connected with a first end plate 21. The first end plate 21 faces the side where the lower plate 6 is located. The output end of the second hydraulic cylinder 20 is connected with a second end plate 22. The second end plate 22 faces the side where the upper plate 4 is located. The distances between the first hydraulic cylinder 19 and the second hydraulic cylinder 20 and the central plane are the same. During the first working stage of processing, the first hydraulic cylinder 19 operates. During the second working stage of processing, the second hydraulic cylinder 20 operates, enabling the first hydraulic cylinder 19 and the second hydraulic cylinder 20 to work alternately.

[0037] In this embodiment, a vertical sliding hole 23 is formed on the surface of the middle plate 5 away from the side where the middle bin 1 is located. A piston 24 is slidably and sealingly arranged in the vertical sliding hole 23. The vertical sliding hole 23 is connected to a horizontal sliding hole 26 through a hydraulic channel 25. A stop block 27 is fixed in the horizontal sliding hole 26. A hose 28 is installed in the stop block 27. One end of the hose 28 communicates with the hydraulic channel 25. The other end of the hose 28 is connected with a spiral telescopic tube 29. The spiral telescopic tube 29 is coaxially sleeved on the outer side of the elastic spring 18. The spiral telescopic tube 29 is made of rubber material and has the same structure as a cylindrical spring in its normal state. Both ends of the spiral telescopic tube 29 are fixed to the slider 8 and the limit plate 17 respectively and can expand after hydraulic oil is introduced.

[0038] In this embodiment, an elastic limiting device 30 for limiting the piston 24 is installed in the vertical sliding hole 23 to prevent the piston 24 from coming out. A heater 31 is installed on the inner side of the middle bin body 1 for heating the cavity.

[0039] In this embodiment, a third hydraulic cylinder 32 is fixed on the middle plate 5. The output end of the third hydraulic cylinder 32 is connected to a bracket 33. A guide rod 34 is fixed on the bracket 33. A guide sleeve 35 matched with the guide rod 34 is installed on the side surface of the middle bin body 1. The guide rod 34 passes through the guide sleeve 35 and extends into the middle bin body 1. By setting the third hydraulic cylinder 32, the workpiece can be pushed from the side after processing, which is convenient for blanking.
