Technical Field

[0001] The invention relates to the technical field of woodworking engraving machines, in particular to a woodworking engraving machine with an anti-dislocation function. Background Art

[0002] Laser engraving machine is an advanced equipment that uses laser to engrave the materials to be engraved. During the laser engraving process of wooden boards, each wooden board material needs to be zeroed and positioned first, and the wooden board to be engraved is placed on the processing table of the engraving machine to ensure that the wooden board is placed stably without tilting or skewing. The existing woodworking engraving machine needs to use multiple positioning structures to position and press the wooden board, and the positioning efficiency is not high. In addition, the wooden board is positioned separately on all sides, which makes it inconvenient to place the wooden board in the center of the processing table, which brings trouble to the subsequent zeroing and positioning of the wooden board.

The anti-dislocation device includes: a placement table, a fixed block, a connecting plate, a first movable arm, a second movable arm, a fixed cylinder, a bearing, a screw, a movable sleeve, a positioning plate, a rotating rod, a first bevel gear, a handle, and a second bevel gear. By setting the anti-dislocation device, it is convenient to support and fix the object to be engraved. When fixing, the user pulls the second movable arm by hand to move, so that the positioning plate at the lower end of the first movable arm can be moved to any position on the placement table with the cooperation of the first movable arm, the second movable arm and the damping shaft, and then the user can adjust the position of the positioning plate according to the height of the object to support and fix it. However, the device is not convenient for centering, fixing and pressing the wooden board material, and the positioning operation is also cumbersome, which reduces the clamping efficiency of the wooden board and hinders the zero positioning operation process of the wooden board. The flexibility of use is not high, and there are certain defects.

[0031] 1. A positioning mechanism is provided. The wooden board to be processed is placed in the middle of the top of the placing table, and the driving motor is started. The driving motor drives the double-headed screw to rotate. The rotation of the double-headed screw causes the two moving blocks thereon to approach each other, and the moving block drives the mounting plate and the adjusting rod to move. The adjusting rod drives the sliding column to slide inside the limiting inclined groove.

The sliding column drives the fixed sleeve to move obliquely, and the fixed sleeve drives the sliding rod and the clamping plate to press against the corner of the wooden board. Since the clamping plates on all sides are symmetrically arranged and move synchronously, the clamping plate is squeezed to drive the sliding rod to slide into the fixed sleeve, and the clamping plate compresses spring 1, and the movement of the clamping plate drives the two clamping plates to approach each other, so that the two clamping plates clamp the side edges of the corner, and the telescopic hose is compressed for a certain distance. The elastic coefficient of spring 2 is greater than that of spring 1, and the moving block and the mounting plate move synchronously; until the fixed sleeve After the clamping does not move, the driving motor continues to rotate. At this time, the mounting plate does not move, and the moving block drives the sliding block to move inside the bottom groove. The sliding block compresses the spring 2, and the sliding block can drive the push rod to move, so that the push rod slides into the air hole, and the connecting hole is blocked by the push rod. The push rod squeezes the air inside the air hole, so that the air is discharged from the exhaust pipe. The one-way valve on the exhaust pipe prevents air from flowing back, so that the telescopic hose and the adsorption groove are in a negative pressure state, so that it is easy to adsorb the bottom surface of the wooden board, which assists in the positioning of the wooden board. When the clamping is subsequently released, the push rod releases the blockage of the connecting hole to allow air to enter, and the internal pressure of the telescopic hose is restored, which is convenient for the next operation, improves the centering clamping effect, and is convenient for zeroing positioning during engraving. It solves the problem that the device is not convenient for centering, fixing and pressing the wooden board material, and the positioning operation is also cumbersome, which reduces the clamping efficiency of the wooden board and also hinders the zeroing positioning operation process of the wooden board.

[0032] 2. A moving mechanism is provided. By starting the servo motor, the servo motor drives the threaded rod to rotate. The rotation of the threaded rod causes the vertical plate to move. The side plate limits the vertical plate, so that the vertical plate and the horizontal plate can be adjusted horizontally, thereby facilitating the horizontal movement of the laser engraving device on the horizontal plate. By starting the linear motor, the linear motor drives the longitudinal adjustment of the laser engraving device, which facilitates the longitudinal movement of the position of the laser engraving device, thereby facilitating the flexible adjustment of the position of the laser engraving device and facilitating the laser engraving processing of the wooden board.

[0055] The top end of the communicating hole 621 is connected to the air hole 620 , and the bottom end of the communicating hole 621 is connected to the outside of the connecting plate 615 . The connecting plate 615 is located above the double-ended screw rod 63 .

[0056] A telescopic hose 622 is connected to the side of the connecting plate 615 away from the mounting plate 65, an exhaust pipe 623 is connected to the outside of the telescopic hose 622, a one-way valve is installed on the outside of the exhaust pipe 623, an adsorption groove 624 is symmetrically opened in the middle of the interior of the placement table 1, and one end of the telescopic hose 622 away from the connecting plate 615 is connected to the adsorption groove 624.

[0057] Embodiment 1: Figure 1-Figure 8 As shown, a positioning mechanism 6 is provided. By placing the wooden board to be processed in the middle of the top of the placing table 1, the driving motor 62 is started. The driving motor 62 drives the double-headed screw 63 to rotate. The double-headed screw 63 rotates so that the two moving blocks 64 thereon are close to each other. The moving block 64 drives the mounting plate 65 and the adjusting rod 66 to move. The adjusting rod 66 drives the sliding column 68 to slide inside the limiting inclined groove 67. Since the limiting inclined groove 67 is inclined, the adjusting rod 66 will slide inside the mounting plate 65, thereby assisting the movement of the sliding column 68.

[0058] The sliding column 68 drives the fixed sleeve 69 to move obliquely, and the fixed sleeve 69 drives the sliding rod 610 and the clamping plate 611 to press against the corner of the wooden board. Since the clamping plates 611 on all sides are symmetrically arranged and move synchronously, the clamping plate 611 is squeezed to drive the sliding rod 610 to slide into the fixed sleeve 69, and the clamping plate 611 compresses the spring 1 612, and the movement of the clamping plate 611 drives the two clamping plates 614 to approach each other, so that the two clamping plates 614 clamp the side edges of the corner, and the telescopic hose 622 is compressed for a distance. The elastic coefficient of the spring 2 618 is greater than that of the spring 1 612, and the moving block 64 and the mounting plate 65 move synchronously.

The rotation of the threaded rod 75 causes the vertical plate 73 to move. The side plate 71 limits the vertical plate 73, so that the vertical plate 73 and the horizontal plate 3 can be adjusted laterally, thereby facilitating the horizontal movement of the laser engraving device 5 on the horizontal plate 3. By starting the linear motor 4, the linear motor 4 drives the laser engraving device 5 to adjust longitudinally, which facilitates the longitudinal movement of the position of the laser engraving device 5, thereby facilitating the flexible adjustment of the position of the laser engraving device 5 and facilitating the laser engraving processing of the wooden board.
