DETAILED DESCRIPTION

[0017] like Figures 1 to 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.

[0018] 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.

[0019] 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.

[0020] The present invention provides a middle warehouse body 1 that can move up and down and can be turned over, so that its working table can cooperate with the upper or lower warehouse body 3 respectively to realize a double-station or multi-station switching function. This modular design not only enhances the adaptability of the equipment, so that it can match the processing requirements of workpieces of different sizes, but also improves production efficiency.

[0021] The working principle and process of the present invention application are as follows: 1. Initial positioning stage: The middle warehouse body 1 is in the initial position, with its lower end facing the side where the lower warehouse body 3 is located. At this time, the upper warehouse body 2 is in a standby state, the slider 8 is positioned by the automatic locking member, and the displacement drive assembly remains in a retracted state. The heater 31 is started to preheat the workpiece to be processed inside the middle warehouse body 1.

[0022] 2. First station processing stage: the automatic locking part is released, the lower warehouse body 3 is loaded with the coating material, and the displacement drive 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, and the hydraulic oil is pressed into the horizontal sliding hole 26 through the hydraulic channel 25, and the hydraulic oil is pushed into the spiral telescopic tube 29 through the hose 28, and then squeezes the spiral telescopic tube 29. The spiral telescopic tube 29 breaks free from the restraint of the elastic tension spring 18 and opens, so that the pin 16 temporarily detaches from the column 7, reducing friction resistance; after the lower warehouse body 3 and the middle warehouse body 1 are combined, the pressure in the lower warehouse body 3 and the middle warehouse body 1 is changed, and the coating of the lower surface of the workpiece is completed under the action of the pressure difference.

[0023] 3. Turning stage: the first hydraulic cylinder 19 is retracted, the slide block 8 is positioned again by the automatic locking member, the rotation drive device 9 is started, and the output shaft 10 drives the middle plate 5 and the middle warehouse body 1 to turn over 180°, and the turning is completed. At this time, the piston 24 faces downward.

[0024] 4. Second station processing stage: After the middle warehouse body 1 is turned over, the displacement drive assembly moves in the opposite direction, so that the lower end surface of the middle warehouse body 1 is closely matched with the lower end surface of the upper warehouse body 2 to form a second work surface. The coating material is introduced into the upper warehouse body 2 to complete the processing of the upper surface of the workpiece. If repeated processing is required, it can be turned over again and lowered to the lower warehouse body 3 station to realize the cycle operation.

[0025] In this embodiment, a notch 11 for installing the slider 8 is provided on the side of the middle plate 5, an inner arc surface 12 is formed on the inner side of the notch 11, and outer arc surfaces 13 that cooperate with the inner arc surface 12 are formed on both sides of the slider 8, and the outer end of the slider 8 protrudes from the side 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, which significantly improves the structural rigidity and torsion 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-centering effect to avoid 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 of the middle plate 5.

[0026] In this embodiment, a pin hole 14 is provided on the side of the slider 8, and the inner end of the pin hole 14 is connected to the guide hole 15 matched between the slider 8 and the column 7. The automatic locking member includes a pin 16, a limit plate 17, and an elastic tension spring 18. The inner side of the pin 16 is slidably arranged in the pin hole 14, and the outer end of the pin 16 is fixedly connected to the limit plate 17. The limit plate 17 and the slider 8 are connected with an elastic tension spring 18. The elastic tension spring 18 is sleeved on the outer side of the pin 16. Under the elastic tension of the elastic tension 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 achieve the locking of the slider 8. It can be understood that in order to reduce the damage caused by the pin 16 to the surface of the column 7, a rubber block can be fixed at the inner end of the pin 16, and the friction can also be increased.

[0027] In this embodiment, the displacement drive 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 to the first end plate 21, and 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 to the second end plate 22, and 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 center plane are the same. During the first station processing stage, the first hydraulic cylinder 19 is actuated, and during the second station processing stage, the second hydraulic cylinder 20 is actuated, so that the first hydraulic cylinder 19 and the second hydraulic cylinder 20 can achieve alternating operation.

[0028] In this embodiment, a vertical sliding hole 23 is provided on the surface of the middle plate 5 away from the middle warehouse body 1, a piston 24 is provided in the vertical sliding hole 23 for sliding sealing, the vertical sliding hole 23 is connected to the horizontal sliding hole 26 through a hydraulic channel 25, a stopper 27 is fixed in the horizontal sliding hole 26, a hose 28 is installed in the stopper 27, one end of the hose 28 is connected to the hydraulic channel 25, the other end of the hose 28 is connected to a spiral telescopic tube 29, and the spiral telescopic tube 29 is coaxially sleeved on the outside of the elastic tension spring 18. The spiral telescopic tube 29 is made of rubber material, and its structure under normal conditions is the same as that of a columnar spring. The two ends of the spiral telescopic tube 29 are respectively fixed to the slider 8 and the limit plate 17, and can expand after the hydraulic oil is passed.

[0029] 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 slipping out. A heater 31 is installed on the inner side of the middle warehouse body 1 to heat the cavity.

[0030] In this embodiment, a third hydraulic cylinder 32 is fixed on the middle plate 5, a bracket 33 is connected to the output end of the third hydraulic cylinder 32, a guide rod 34 is fixed on the bracket 33, a guide sleeve 35 matching the guide rod 34 is installed on the side of the middle warehouse body 1, and the guide rod 34 passes through the guide sleeve 35 and extends into the middle warehouse body 1.
