DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1 to 3 , in the embodiment of the present utility model, a furniture painting auxiliary clamping device includes a workbench 1. Two first slide rails 2 are provided at the bottom of the workbench 1. The two first slide rails 2 are symmetrically distributed at both ends of the bottom of the workbench 1. A moving seat 3 is slidably assembled in the length direction of the two first slide rails 2. The inner end of the upper surface of the moving seat 3 is fixedly connected with a second slide rail 5. A sliding seat 6 is slidably assembled in the length direction of the second slide rail 5;

[0021] The lower end of the sliding seat 6 is rotatably connected to a clamping block 9 through a shaft rod. Two rollers 10 are rotatably connected to both outer ends of the clamping block 9. Two elastic members 8 are connected between the sliding seat 6 and the clamping block 9. The two elastic members 8 are symmetrically arranged. A driving mechanism 4 is provided between the bottom of the workbench 1 and the two moving seats 3 for driving the moving seat 3 to move along the length direction of the two first slide rails 2 to adjust the distance between the two moving seats 3; The moving seat 3 is slidably connected to the first slide rail 2.

[0022] In this embodiment: Before the existing clamping device clamps and fixes the furniture board, manual assistance is required to clamp and fix the furniture board, which not only wastes manpower and material resources, but also takes a lot of time for manual operation, greatly reducing the work efficiency. Therefore, in this solution, the driving mechanism 4 drives the four clamping blocks 9 to cooperate to perform self-positioning clamping on the furniture board. The staff only needs to place the furniture board between the four clamping blocks 9, and then the driving mechanism 4 can drive the four clamping blocks 9 to gradually approach the four corners of the furniture board, and can correct and clamp the inclined furniture board, providing a positioning and loading function for the existing automatic painting equipment; In addition, this solution can be applied to clamping furniture boards of different sizes and specifications, greatly improving the adaptability of use.

[0023] Specifically, first place the furniture board in the interval between the four clamping blocks 9, and then control the two moving seats 3 to move closer by the driving mechanism 4. The moving seat 3 drives the four clamping blocks 9 to respectively contact the four corners of the furniture board before and after, thereby pushing the furniture board to the middle of the workbench 1 and performing limit clamping on the four corners of the furniture board.

[0024] Please pay special attention to Figure 2, the driving mechanism 4 includes two first fixed seats 401 and two second fixed seats 402. The two first fixed seats 401 are respectively located at both ends of the bottom of the workbench 1, and the two second fixed seats 402 are respectively located in the middle of the bottom end of the workbench 1. The two first fixed seats 401 and the two second fixed seats 402 are on the same horizontal line;

[0025] A lead screw 403 is rotatably connected between the first fixed seat 401 and the second fixed seat 402 through a bearing. A threaded seat 404 is fixedly connected to the middle of the moving seat 3. The threaded seat 404 is threadedly connected to the lead screw 403. A first bevel gear 405 is arranged on the outer end of the lead screw 403 close to the second fixed seat 402. A motor 406 is installed on one side of the bottom of the workbench 1 close to the first bevel gear 405. A second bevel gear 407 is arranged at the output end of the motor 406. The second bevel gear 407 meshes with the first bevel gear 405; the thread directions of the two lead screws 403 are opposite.

[0026] In this embodiment: The motor 406 drives the second bevel gear 407 to drive the two lead screws 403 to rotate relatively. The threaded seat 4 connected to the lead screw 403 will move along the length direction of the lead screw 403, thereby realizing the horizontal left and right movement of the moving seat 3. It should be noted that the thread directions of the two lead screws 403 are opposite. Therefore, when the motor 406 drives the second bevel gear 407 to drive the two lead screws 403 to rotate relatively, either the moving seats 3 move closer to each other or the moving seats 3 move away from each other to realize the clamping or loosening action.

[0027] Please refer specifically to Figure 3 , the clamping block 9 has a right-angled "V" shape; the elastic member 8 is a rubber band or a tension spring.

[0028] In this embodiment: The structure of the clamping block 9 can be adapted to the corners of the household board, so it is more stable during clamping; when the clamping block 9 is not affected by force, the elastic member 8 can limit the relative rotation between the clamping block 9 and the sliding seat 6; when the clamping block 9 touches the household board, it can force the elastic member 8 to deform, thereby pushing the clamping block 9 to rotate relative to the sliding seat 6; in addition, after releasing the clamping of the household board, the clamping block 9 and the sliding seat 6 return to the initial position under the action of the elastic member 8 to prepare for clamping the next household board.

[0029] Please refer specifically to Figure 1 , a fastening bolt 7 is threadedly connected to one end of the sliding seat 6 close to the second slide rail 5, which is used to limit the sliding of the sliding seat 6 along the length direction of the second slide rail 5, so that the sliding seat 6 is limited in any length direction of the second slide rail 5.

[0030] In this embodiment: By tightening the fastening bolt 7, the lower end of the fastening bolt 7 can be forced to abut against the second slide rail 5, thereby restricting the movement of the sliding seat 6. This structure is to adapt to furniture boards of different specifications and sizes. By measuring the size of the furniture board in advance and adjusting the position of the sliding seat 6, the distance between the two sliding seats 6 is ensured to match the length of one side of the furniture board.

[0031] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, should be covered within the protection scope of the present invention.
