Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting, in particular to a five-axis laser cutting device. Background Art

[0002] As a laser processing equipment for cutting three-dimensional parts with complex curved surfaces, five-axis laser cutting machines have been widely used in Europe and Japan, and the market demand is growing. In the 1970s and 1980s, Europe, Italy, Japan and other countries have successively developed laser three-dimensional machines, and the technology has now become relatively mature.

[0003] Existing patent CN215747151U, a five-axis laser cutting machine, includes a workbench, the top of the workbench is fixedly installed with side panels near both sides, and the tops of the two side panels are fixedly installed with two fixed blocks. The five-axis laser cutting machine is provided with L-shaped plates near both sides of the top of the workbench, and two first springs are fixed on the side where the two L-shaped plates are close to each other, and the baffle second spring is fixed on the side where the first springs are close to each other. When the workpiece needs to be placed, the baffle second springs on both sides are moved to both sides, and the first springs on both sides are compressed at the same time, and then the workpiece is placed between the two baffle second springs. At this time, the baffle second springs on both sides are released, so that the first springs on both sides are reset, and the baffle second springs on both sides clamp the workpiece, thereby achieving the effect of convenient clamping and fixing of the workpiece.

[0004] Although the workpiece is clamped by two baffles and the first spring, the baffle is only connected to the L-shaped plate through the first spring. When the workpiece is a plate or thin, only the lower end of the baffle contacts the workpiece. When the first spring is reset, the lower end of the baffle contacts the workpiece and squeezes the first spring, but the upper end of the baffle does not move, causing the baffle to tilt, reducing the clamping effect on the workpiece, and the clamping is not stable enough. The position of the L-shaped plate is fixed. When the maximum length of the workpiece is less than the minimum distance between the two baffles, the baffle loses its fixing effect. In addition, although the laser cutting head can move forward, backward, left and right, it cannot be fine-tuned up and down.

[0005] So we propose a five-axis laser cutting equipment to solve the above-mentioned problems. Utility Model Content

[0006] The purpose of the utility model is to provide a five-axis laser cutting device to solve the problem mentioned in the above background technology that the baffle is only connected to the L-shaped plate through the first spring.

[0008] Preferably, the maximum length of the two slide grooves is smaller than the minimum length between the two electric slide rails.

[0009] The above technical solution is adopted to prevent the support plate from hitting the electric slide rail 1 when moving, thereby causing damage.

[0010] Preferably, the clamping mechanism includes a support plate, a sleeve, a telescopic rod and a splint, three sleeves are provided on the side closest to the two support plates, and a groove 1 is provided in each sleeve, and the inner wall side of the groove 1 is connected to one end of a corresponding spring, and the other end of the spring is fixedly connected to one end of the corresponding telescopic rod, and the other ends of the three telescopic rods are fixedly connected to the side of the splint.

[0011] By adopting the above technical solution, the workpiece is clamped by two clamps, and the clamps are connected to the support plate through sleeves and telescopic rods, so as to avoid the clamps tilting and weakening of the clamping effect when the workpiece is thin.

[0012] Preferably, the bottom surfaces at both ends of the longest side of the support plate are fixedly connected to the upper ends of the connecting plates.

[0013] By adopting the above technical solution, the connecting plate drives the supporting plate to move.

[0014] Preferably, the transmission mechanism includes a bidirectional screw, a limit block, a bidirectional motor, a worm and a worm wheel. A bidirectional screw is provided at both front and rear ends of the groove 2, and both ends of the two bidirectional screws are axially connected to the left and right sides of the inner wall of the groove 2 respectively. Two limit blocks are provided on the two bidirectional screws. A bidirectional motor is provided in the middle of the bottom surface of the inner wall of the groove 2, both ends of the bidirectional motor are axially connected to one end of the worm, and the other ends of the two worms are axially connected to the front and rear sides of the inner wall of the groove 2 respectively. The two worm wheels are respectively arranged in the middle of the two bidirectional screws, and the two worm wheels are respectively meshed with the two worms.

[0015] By adopting the above technical solution, the bidirectional motor drives the bidirectional screw to rotate through the worm and the worm wheel.

[0016] Preferably, both ends of the bidirectional screw are respectively threadedly connected to the lower ends of two corresponding connecting plates, and the lower ends of the two connecting plates movably penetrate the corresponding sliding grooves.

[0017] By adopting the above technical solution, the bidirectional screw rotates through the connecting plate to drive the two support plates to move closer to or away from each other.

[0018] Preferably, the two limit blocks are symmetrically arranged with corresponding worm gears.

[0019] By adopting the above technical solution, the limit block limits the connection plate to prevent the connection plate from moving to the worm gear and causing damage to the worm gear.

[0020] Compared with the prior art, the utility model has the following beneficial effects: a five-axis laser cutting device can fine-tune the laser cutting head up and down through the electric slide rail and the connecting block. The support plate is connected to the clamping plate through a sleeve and a telescopic rod, which effectively avoids the phenomenon that the clamping plate will tilt when the workpiece is thin. The bidirectional motor drives the two support plates to approach each other through the worm, worm wheel, bidirectional screw and connecting plate, and can clamp workpieces of different lengths, thereby increasing the scope of application and improving practicality.

[0021] 1. The connecting block moves up and down on the electric slide rail 3, driving the laser cutting head to move up and down for fine adjustment, so that the laser cutting head can cut the workpiece more accurately.

[0022] 2. When clamping the workpiece, the bidirectional motor drives the two worm wheels to rotate through the two worms, and the rotation of the worm wheels drives the two bidirectional screws to rotate, so that the connecting plate drives the supporting plates to move closer or farther away from each other to adapt to the length of the workpiece and clamp the workpiece. When the clamping plate contacts both ends of the workpiece and clamps the workpiece, the clamping plate drives the telescopic rod to move in the sleeve, and the clamping plate is limited and fixed by the sleeve and the telescopic rod to prevent the clamping plate from tilting when clamping the workpiece, resulting in a weakening of the clamping effect of the clamping plate on the workpiece. During cutting, when the workpiece vibrates, the spring reduces the impact of the vibration on the clamping plate, thereby buffering the workpiece. BRIEF DESCRIPTION OF THE DRAWINGS
