DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] like Figure 1-Figure 9 As shown, the utility model is a wooden board flipping clamping mechanism, comprising a processing workbench 1 and two groups of clamping and flipping devices 2 symmetrically arranged, the clamping and flipping devices 2 are arranged on the processing workbench 1, the clamping and flipping devices 2 include a lifting seat 4, a rotating shaft 5, a flipping assembly 6 and a clamping assembly 7, a stand 3 is provided on the processing workbench 1, the lifting seat 4 is slidably arranged on the stand 3, the rotating shaft 5 is engaged and rotatably arranged on the lifting seat 4, the clamping assembly 7 is arranged on the rotating shaft 5, the flipping assembly 6 includes a bracket 8, a collar 9, a fixing rod 10, a sleeve 11, a gear 12 and a rack 13, the bracket 8 is provided with a second slider 25, the lifting seat 4 is provided with a second slide groove 26, the bracket 8 is engaged and slidably arranged in the second slide groove 26 through the second slider 25 Inside, the ring 9 is arranged on the bracket 8, the fixed rod 10 is arranged on the ring 9, the sleeve 11 is rotatably arranged in the ring 9 and is slidably sleeved on the rotating shaft 5, the gear 12 is sleeved on the sleeve 11, and the rack 13 is arranged on the stand 3, the gear 12 can mesh with the rack 13, and the upper and lower sides of the stand 3 are respectively provided with an upper sliding guide seat 14 and a lower sliding guide seat 15, and the upper sliding guide seat 14 and the lower sliding guide seat 15 are both provided with a guide inclined groove 16 matched with the fixed rod 10; the stand 3 is provided with a cylinder 22, and the lifting seat 4 is arranged on the output shaft of the cylinder 22; the lifting seat 4 is provided with a first slider 23, and the stand 3 is provided with a first slide groove 24, and the first slider 23 is slidably arranged in the first slide groove 24.

[0024] The clamping assembly 7 includes a C-shaped clamp 17, a threaded rod 18 and a pressure plate 19. The C-shaped clamp 17 is arranged on the rotating shaft 5. The threaded rod 18 is connected to the C-shaped clamp 17 by threads. The pressure plate 19 is rotatably arranged on the threaded rod 18. A hand wheel 20 is arranged on the top of the threaded rod 18; an anti-slip pad 21 is arranged at the bottom of the pressure plate 19.

[0025] During specific use, the wooden board is placed on the C-shaped clamp 17, and then the hand wheel 20 is turned. The hand wheel 20 drives the threaded rod 18 to rotate, and the threaded rod 18 drives the pressure plate 19 to move downward. The wooden board can be pressed and fixed by the pressure plate 19, and the clamping components 7 on both sides can fix the two ends of the wooden board respectively, so as to better ensure the stability of the wooden board during the processing. The anti-slip pad 21 can increase the friction between the wooden board and the pressure plate 19, so that the fixing effect is better.

[0026] When the wooden board needs to be turned over, the cylinder 22 is started, and the lifting seat 4 is driven to move upward by the cylinder 22, and the lifting seat 4 drives the rotating shaft 5, the clamping assembly 7, the bracket 8, the collar 9, the fixing rod 10, the sleeve 11 and the gear 12 to move upward. In the process of the gear 12 moving upward, it will mesh with the rack 13. After the gear 12 meshes with the rack 13, as the lifting seat 4 continues to move upward, the gear 12 will rotate, the gear 12 drives the sleeve 11 to rotate, the sleeve 11 drives the rotating shaft 5 to rotate, the rotating shaft 5 drives the clamping assembly 7 to rotate, and the clamping assembly 7 drives the wooden board to be turned 180 degrees. , thereby realizing the automatic turning over of the wooden board. After the turning over of the wooden board is completed, the lifting seat 4 continues to move upward, thereby driving the fixed rod 10 to contact the upper sliding guide seat 14, and under the action of the guide inclined groove 16 on the upper sliding guide seat 14, the fixed rod 10 slides to the side away from the stand 3, and the fixed rod 10 drives the ring 9, the bracket 8, the sleeve 11 and the gear 12 to slide to the side away from the stand 3, so that the gear 12 and the rack 13 are staggered, and then the cylinder 22 is driven to drive the lifting seat 4 to move downward, and the wooden board is lowered to a lower place, which is convenient for the staff to process the wooden board. Because the gear 12 and the rack 13 are staggered when the lifting seat 4 moves downward, when the gear 12 passes the rack 13, the gear 12 will not mesh with the rack 13, and will not rotate, so the wooden board will not be turned over again during the descent process. When the lifting seat 4 drives the fixed rod 10 to move down to the lower sliding guide seat 15, under the action of the guiding inclined groove 16 on the lower sliding guide seat 15, the fixed rod 10 slides to the side close to the stand 3, thereby driving the gear 12 to slide to the side close to the stand 3, so that the gear 12 returns to the initial position and can mesh with the rack 13 again.

[0027] From the above content, it can be seen that when the processing of one side of the wooden board is completed, the cylinder 22 is started, and the wooden board is driven to move upward by the cylinder 22. During the upward movement, the wooden board is automatically turned over. After the turning over is completed, the cylinder 22 is driven to drive the wooden board to move downward. During the downward movement of the wooden board, it will not be turned over. After the wooden board is lowered to a lower position, the staff can process the other side of the wooden board.

[0028] To sum up, the present invention is provided with two sets of clamping and turning devices 2, through which the wooden board can be fixed from both sides respectively, so as to better ensure the stability of the wooden board during the processing. At the same time, the clamping and turning devices 2 can also realize automatic turning over of the wooden board, which makes the operation simpler and saves more manpower.
