Description

Technical Field

[0001] The utility model relates to the technical field of double-station laser tube cutting machines, in particular to a gantry for double-station laser tube cutting machines. Background Art

[0002] The laser tube cutting machine is a professional pipe laser cutting equipment with a high degree of integration and linkage CNC functions. It uses a laser beam to form a thin line on the surface of the tube and cuts the tube by moving the laser head.

[0003] Laser tube cutting machines are widely used in various manufacturing and processing industries such as sheet metal processing, aviation, aerospace, electronics, electrical appliances, subway accessories, automobiles, grain machinery, textile machinery, engineering machinery, precision accessories, ships, metallurgical equipment, elevators, household appliances, craft gifts, tool processing, decoration, advertising, metal external processing, kitchenware processing, etc.

[0004] The laser tube cutting machine needs to use a laser cutting head installed on a gantry to process the tube. During the process of cutting the tube, the gantry needs to drive the laser cutting head to move in multiple directions, so as to cut the tube at multiple angles. At present, the common gantry on the market is not flexible enough when driving the laser cutting head to move, which limits the cutting and forming of the tube to a certain extent.

[0005] Therefore, the present application provides a gantry for a double-station laser tube cutting machine to overcome the defects of the prior art. Utility Model Content

[0006] The utility model aims to solve the problem that the existing gantry is not flexible enough when driving the laser cutting head to move, thereby limiting the cutting and forming of pipes.

[0007] The technical solution of this utility model provides a gantry for a double-station laser tube cutting machine, the core features of which are summarized as follows:

[0008] The machine primarily consists of a bed, gantry, laser cutting head, protective housing, chuck cover, and a clamping and rotating mechanism. A sliding connection structure is cleverly designed on the top of the bed to provide stable support for the gantry. The laser cutting head is flexibly and rotatably connected to the gantry, ensuring precise cutting. The protective housing is fixed to one end of the bed, while the chuck cover slides onto the other. Both incorporate a clamping and rotating mechanism to facilitate the secure and rotating processing of pipes. The gantry is strategically positioned between the protective housing and the chuck cover to optimize space utilization.

[0009] Two rails and a rack are fixed to either side of the bed, their bases firmly fixed to the top. The rails ensure smooth sliding of the gantry's base, while the rack, through its meshing mechanism, drives the gantry precisely along a pre-set path.

[0010] The gantry structure has distinct layers and consists of a support frame, a horizontal transverse moving mechanism, a horizontal longitudinal moving mechanism, and a vertical moving mechanism. The horizontal transverse moving mechanism has a built-in motor 1 and gear 1, which drives the gantry to move horizontally along the bed through rack 1. The horizontal longitudinal moving mechanism is driven by a cylinder, and the longitudinal adjustment of the gantry on the support frame is achieved through the linkage of the piston rod and the sliding connection. The vertical moving mechanism uses motor 2 and gear 2, in conjunction with rack 2 and slide rail 3, to drive the laser cutting head for precise vertical positioning. A vertical connecting plate is fixed to the side of the vertical moving mechanism, and motor 3 is installed on the connecting plate. The output shaft of motor 3 passes through the connecting plate and is connected to the laser cutting head for transmission.

[0011] Specifically, the horizontal longitudinal movement mechanism comprises housing 1, a cylinder, a piston rod, a sliding connector, housing 2, and housing 2. Housing 1 is fixed to the top of the support frame. The cylinder, via the piston rod and sliding connector, drives housing 2 to slide along housing 1. Simultaneously, slider 2 on housing 2 slides along slide rail 2 on the support frame, ensuring smooth movement. The connecting column in the vertical movement mechanism not only connects housing 2 to the connecting plate but also, through the coordination of slide rail 3 and slider 3, and the drive of motor 2 and gear 2, enables flexible vertical adjustment of the laser cutting head.

[0012] Furthermore, the design of the first housing is also ingenious, featuring an overhead connection between the lower and upper housings. The design of pressure plates 1 and 2, along with the slide grooves, ensures a secure connection and smooth sliding between the sliding connector and housing 2. The provision of screw holes facilitates the installation and securing of housing 2.

[0013] The vertical movement mechanism comprises a connecting column vertically mounted within housing 2, with rack 2 secured to one side and a connecting plate secured to the other. A vertical slide rail 3 is secured to each side of the connecting column. Two opposing sliders 3 are secured within housing 2, slidingly engaging with these rails. Housing 2 houses motor 2, with gear 2 located at its output end, located within housing 2 and meshing with rack 2 to achieve precise vertical movement.

[0014] In summary, the gantry system for the dual-station laser tube cutting machine, through its precise mechanical design and efficient transmission mechanism, achieves precise positioning and flexible movement of the laser cutting head in three-dimensional space, providing an efficient and accurate solution for tube processing.

[0015] The beneficial effects of the utility model are as follows: the utility model provides a gantry for a double-station laser tube cutting machine, which can drive the laser cutting head on the gantry to move horizontally along the slide rail 1 by setting a motor 1, a gear 1, a slide rail 1, and a rack 1. Under the action of the motor 1, the laser cutting head can be driven to move horizontally along the slide rail 1. By setting a cylinder, a piston rod, and a sliding connection, the cylinder drives the box 2 and the shell 2 to move horizontally and longitudinally along the shell 1 and the slide rail 2 respectively through the sliding connection on the piston rod, and at the same time drives the vertical movement mechanism and the laser cutting head to move horizontally and longitudinally. By setting a motor 2, a gear 2, a rack 2, a slide rail 3 and a slide rail 3, the motor 2 drives the connecting column to move up and down along the slide rail 3 through the gear 2, and then drives the laser cutting head on the connecting plate to move up and down. By setting the motor 3, the laser cutting head can be driven to rotate, thereby realizing cutting of various shapes of tubes, such as round, square, oval or other unconventional shapes, etc., which greatly improves the flexibility and efficiency of tube processing, has higher cutting efficiency, and can perform hole drilling, milling, cutting, stamping and other process operations on the tube, thereby expanding the scope of application of the device.
