AI Technical Summary
In laser pipe cutting machines, the existing technology lacks auxiliary loading devices, resulting in low loading efficiency of pipe materials, high labor costs in the production process, and a safety risk of multi-person collaboration. At the same time, the material at the end of the pipe material is seriously wasted.
A laser pipe cutting machine auxiliary feeding device is designed, which is mainly composed of a fixed bracket, a feeding mechanism and a long inner hole expansion block. The feeding mechanism includes a cylinder, a hinge and an actuator. The actuator is driven to rotate by the cylinder to realize automatic feeding of the pipe; the lengthening inner hole expansion block is clamped to the tail end of the pipe, extending the machining range of the pipe and reducing material waste.
Through this auxiliary loading device, the pipe loading requires only one person to operate, which significantly reduces the labor cost of the production process, avoids the safety risks of multi-person collaboration, and reduces the waste at the end of the pipe.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of laser tube cutting machine tooling, in particular to an auxiliary feeding device for a laser tube cutting machine. Background Art
[0002] Laser tube cutting machine is a kind of laser processing equipment, which is widely used in tube processing. It has the advantages of good end surface quality and high precision when used to process tubes. Laser tube cutting machine is generally not equipped with auxiliary feeding device when it leaves the factory, so enterprises generally use manual feeding. When processing tubes with longer length or heavier weight, at least 3 to 4 people are required to lift the tubes together and put them on the movable tube bracket of the laser tube cutting machine. This has low feeding efficiency and high labor cost in the production process. At the same time, there are also safety issues of multi-person collaboration. In addition, the end of the tube is directly clamped by the tailstock clamping device of the laser tube cutting machine. There will always be a section of the tail end of the tube that cannot be used during cutting, resulting in material waste. Utility Model Content
[0003] In view of the above problems, the utility model proposes a solution, namely, an auxiliary feeding device for a laser tube cutting machine. The utility model adopts a technical solution to solve the above technical problems: an auxiliary feeding device for a laser tube cutting machine, mainly composed of a fixed bracket (1), a feeding mechanism (2) and an inner hole extension tightening block (3); the feeding mechanism (2) is installed on the fixed bracket (1), and the number of the feeding mechanism (2) is 2 sets; the feeding mechanism (2) mainly includes a first hinge (201), a cylinder (202), a second hinge (203), a third hinge (204) and an actuator (205); one end of the cylinder (202) is connected to the fixed bracket (1) through the first hinge (201), one end of the actuator (205) is installed on the fixed bracket (1) through the second hinge (203), and the other end of the cylinder (202) is connected to the actuator (205) through the third hinge (204); the inner hole extension tightening block (3) is installed on the tailstock tube clamping device (402) of the laser tube cutting machine (4). During the feeding process, the two groups of feeding mechanisms (2) move together under the action of the corresponding cylinders (202), and the actuator (205) of the feeding mechanism (2) rotates around the second hinge (203) to transfer the tube (5) from the fixed bracket (1) to the movable tube bracket (403) of the laser tube cutting machine (4), thereby realizing auxiliary feeding of the tube. The head (301) of the extended inner hole expansion block (3) is inserted into the tail end of the tube (5), and the clamping section (302) is fixed on the tailstock clamping device (402), so that the processable range of the tube (5) is extended and the waste of the tail end of the tube is reduced. Through the auxiliary feeding device of the laser tube cutting machine, it is realized that only one person is required to operate the transfer process, the labor cost of the production process is reduced, and the risk of multi-person collaboration is avoided.

DETAILED DESCRIPTION
[0012] like Figures 1 to 5As shown, an auxiliary feeding device for a laser tube cutting machine mainly consists of a fixed bracket (1), a feeding mechanism (2) and an inner hole extension tightening block (3). The feeding mechanism (2) is installed on the fixed bracket (1), and the number of the feeding mechanism (2) is 2 sets; the feeding mechanism (2) mainly consists of a first hinge (201), a cylinder (202), a second hinge (203), a third hinge (204) and an actuator (205); one end of the cylinder (202) is connected to the fixed bracket (1) through the first hinge (201), one end of the actuator (205) is installed on the fixed bracket (1) through the second hinge (203), and the other end of the cylinder (202) is connected to the actuator (205) through the third hinge (204); the inner hole extension tightening block (3) is installed on the tailstock clamping device (402) of the tailstock (404) of the laser tube cutting machine (4). During the feeding process, the two groups of feeding mechanisms (2) are driven by the corresponding cylinders (202) to synchronously drive the actuator (205) to rotate around the second hinge (203), so as to transfer the tube (5) from the fixed bracket (1) to the movable tube bracket (403) of the laser tube cutting machine (4), thereby realizing auxiliary feeding. The fixed bracket (1) is arranged on one side of the body (401) of the laser tube cutting machine (4), and the length direction of the tube (5) is arranged parallel to the length direction of the body (401). Figure 1 and Figure 4 As shown, the clamping end (302) of the extended inner hole expansion block (3) is inserted into the tailstock clamping device (402) and locked, and the head (301) of the extended inner hole expansion block (3) is inserted into the tail end of the tube (5) and uses its own expansion force to lock the end of the tube (5). The extended inner hole expansion block (3) lengthens the processable range of the tube (5) and reduces material waste.
[0013] like Figure 6 As shown, the inner hole expansion block (3) is composed of a head (301) and a clamping section (302). The head (301) will produce a certain amount of deformation under the action of external force, so that it is tightly attached to the outer tube, thereby fixing the tail end of the tube (5).
[0014] In practical applications, the shape and size of the head of the actuator (205) and the shape of the extended inner hole expansion block (3) can be changed to adapt to pipes with different cross-sections.
