DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figures 1-4 , the pallet processing and positioning device provides two technical solutions:

[0024] The first embodiment comprises a base 1 and a support plate 2, wherein the support plate 2 is provided with an inner support assembly 4 for positioning the tray, and an adjustment assembly 3 is provided between the base 1 and the support plate 2 and is used to adjust the position of the tray;

[0025] The internal support assembly 4 includes a groove opened on the top of the support plate 2, and the bottom of the inner wall of the groove is rotatably connected to a disc 41, and the top of the disc 41 is rotatably connected to two left and right pull rods 42. The other ends of the two pull rods 42 are rotatably connected to the internal support blocks 43, and the internal support blocks 43 are slidably connected to the inner surface of the groove.

[0026] An L-shaped rod 44 is fixedly connected to the bottom of the disc 41, an arc-shaped groove is provided at the bottom of the support plate 2, and the L-shaped rod 44 extends from the arc-shaped groove to the bottom of the disc 41, and a second hydraulic cylinder 45 is rotatably connected to the bottom of the support plate 2, and the telescopic end of the second hydraulic cylinder 45 is rotatably connected to the L-shaped rod 44.

[0027] The pallet is positioned by designing an inner support assembly 4 that is compatible with the pallet structure. The inner support assembly 4 is hidden under the pallet, and thus when the pallet is being painted, the paint can be effectively prevented from being sprayed onto the parts of the positioning assembly, thereby improving the practicality of the device when in use.

[0028] The second embodiment is mainly different from the first embodiment in that: the adjustment component 3 includes a rotating shaft 31, the rotating shaft 31 is rotatably connected to the top of the base 1, the top of the rotating shaft 31 is fixedly connected to a first U-shaped seat 32, and a driven gear 33 is fixedly connected to the lower surface of the first U-shaped seat 32. An adjustment motor 34 is fixedly connected to the base 1 through a bracket, and the output end of the adjustment motor 34 is fixedly connected to a driving gear 35, and the driving gear 35 is engaged with the driven gear 33 for transmission. The left and right sides of the rotating shaft 31 are rotatably connected to the first hydraulic cylinder 36, the support plate 2 is rotatably connected to the first U-shaped seat 32, and the bottom of the support plate 2 is fixedly connected to two left and right second U-shaped seats 37, and the two second U-shaped seats 37 are rotatably connected to the telescopic ends of the two first hydraulic cylinders 36 respectively.

[0029] When the pallet is being spray-painted, the angle and tilt angle of the pallet are adjusted by adjusting the cooperation of the component 3, so that the spray gun can complete the full painting operation on the pallet at the same position, thereby improving the convenience of using the positioning device.

[0030] When in use, the pallet is placed above the support plate 2, the second hydraulic cylinder 45 is started, and the L-shaped rod 44 is pushed to move, thereby causing the disc 41 to rotate. The disc 41 rotates and the two inner support blocks 43 are in principle with each other through the two pull rods 42, thereby internally supporting the positioning of the pallet. In addition, during processing, the adjustment motor 34 is started as needed, the adjustment motor 34 works and drives the driving gear 35 to rotate, the driving gear 35 rotates and transmits it to the driven gear 33, the driven gear 33 rotates and drives the rotating shaft 31 to rotate, the rotating shaft 31 rotates and drives the support plate 2 to rotate through the first U-shaped seat 32, thereby changing the angle of the first U-shaped seat 32. In addition, the two first hydraulic cylinders 36 can be started at the same time, the first hydraulic cylinder 36 works and changes the inclination angle of the first U-shaped seat 32. When the two first hydraulic cylinders 36 are working, the length of the telescopic end of the other first hydraulic cylinder 36 increases and the other decreases.
