Description

Technical Field

[0001] This utility model relates to the field of pipe cutting machine technology, and in particular to a laser pipe cutting machine. Background Technology

[0002] In existing technology, laser pipe cutting machines are devices used to cut steel pipes and have been applied in various steel pipe processing stages. Laser pipe cutting machines utilize laser technology for pipe cutting, featuring high precision and high efficiency.

[0003] A search revealed Chinese patent application number 202421606550.3, which discloses a material support mechanism for a fiber laser tube cutting machine. The mechanism includes a mounting box containing a cylinder. A support plate is fixedly connected to the top of the cylinder. Two sliding holes are formed on the surface of the support plate, and two sliding rods are slidably connected inside each hole. The four sliding rods are divided into two groups. A movable plate is fixedly connected to one end of each group of two sliding rods away from the sliding hole. A sliding groove is formed on the surface of the movable plate, and a slider is slidably connected inside the groove. A clamping plate is fixedly connected to one end of the slider. A motor is fixedly connected to the surface of the movable plate, and a screw is fixedly connected to the output shaft of the motor, with the screw threadedly connected to the inside of the slider. Dual-axis electric push rods are fixedly connected to the opposite surfaces of the two movable plates. A support pad is fixedly connected to the top of the support plate.

[0004] The above-mentioned patent has the following shortcomings: The material support mechanism applied to the fiber laser pipe cutting machine mainly fixes and clamps the steel pipe to ensure that the steel pipe remains stable during the laser cutting process, which is convenient for cutting the steel pipe into specific shapes (the laser cutting head moves along the planned path); however, for some steel pipes that only need to be cut, the structure cannot drive the steel pipe to rotate, which is not conducive to the rapid cutting of the steel pipe.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] A laser tube cutting machine, such as Figures 1 to 4 As shown, it includes: a laser cutting head 3 set at the top of the working mounting base 1 and a steel pipe clamping unit 6 that works in conjunction with the laser cutting head 3; a fixed mounting frame 2 is fixedly installed at the top of the working mounting base 1, and the laser cutting head 3 is set inside the fixed mounting frame 2.

[0029] like Figure 1 As shown, a telescopic cylinder is fixedly installed at the top of the fixed mounting bracket 2, and the laser cutting head 3 is fixedly installed at the bottom of the telescopic end of the telescopic cylinder. This method facilitates the quick adjustment of the distance between the laser cutting head 3 and the steel pipe to be cut, but the steel pipe to be cut needs to rotate itself so that the laser cutting head 3 can perform the melting and cutting work.

[0030] The laser cutting head 3 is used to emit laser light. Its control host (not shown) is installed on one side of the working mounting base 1, and a main controller 4 for controlling the telescopic cylinder, laser cutting head 3 and control host is fixedly installed on one side of the fixed mounting bracket 2. The main controller 4 integrates an operation interface and can preset cutting parameters (such as rotation speed and cutting depth) to reduce the complexity of operation. The distance control of the telescopic cylinder and laser cutting head 3 by the main controller 4 is mainly achieved through a distance detection sensor (not shown). This sensor technology is mature and widely used, and will not be described in detail in this application.

[0031] The laser cutting head 3 is a mature existing technology and is used in a variety of machining machines. This application will not elaborate on it further. At the same time, the installation method of the laser cutting head 3 disclosed in this application is only one of its many installation methods. The specific installation method and working method of the laser cutting head 3 are not limited to the method directly disclosed in this application.

[0032] Multiple movable bases 5 are provided on both sides of the fixed mounting bracket 2. The top of the movable base 5 is integrally formed with a positioning boss. Multiple limiting guide rails are welded to the top of the working mounting base 1. The limiting guide rails are slidably engaged with the bottom of the movable base 5, so that the movable base 5 can move stably on the upper surface of the working mounting base 1, thereby improving the convenience of adjusting the clamping position of the steel pipe clamping unit 6.

[0033] Since the above-mentioned method of cooperating the movable base 5 and the limiting guide rail has been widely used, and the movable base 5 has various movement control methods and mature technology, those skilled in the art can choose practical technical means based on the description of this application without creative effort. Therefore, the limiting guide rail shown in the attached drawings of this application is only a schematic structure.

[0034] Multiple steel pipe clamping units 6 are fixedly installed on the top of multiple movable bases 5 respectively, and the main body of the steel pipe clamping unit 6 is set as a rotating mounting cylinder 601. The front and back sides of the rotating mounting cylinder 601 are integrally formed with positioning connecting cylinders 602. The inner diameter of the positioning connecting cylinder 602 is the same as the inner diameter of the rotating mounting cylinder 601, and the outer diameter is smaller than the outer diameter of the rotating mounting cylinder 601.

[0035] The outer wall of the positioning connecting cylinder 602 is rotatably mounted with a rotating mounting ring 603 via a bearing. Fixed support legs 604 are welded to both sides of the rotating mounting ring 603. Fixed clamping sleeves 605 are fixedly sleeved at the bottom of the fixed support legs 604. Positioning connecting seats 606 are welded to the bottom ends of multiple fixed clamping sleeves 605.

[0036] A sub-controller 607 is fixedly installed on one side of the upper surface of the positioning connector 606. The sub-controller 607 establishes a data link with the main controller 4, and the sub-controllers 607 of multiple steel pipe clamping units 6 are synchronously controlled by the main controller 4.

[0037] The lower surface of the positioning connector 606 is provided with a positioning groove that matches the positioning boss, which facilitates the positioning and installation of the steel pipe clamping unit 6. A motor mounting base 614 is fixedly installed on one side of the upper surface of the positioning connector 606. A servo motor 613 is fixedly installed on the top of the motor mounting base 614. A drive bevel gear 612 is fixedly installed on the output shaft of the servo motor 613. The servo motor 613 is controlled by the sub-controller 607.

[0038] One of the positioning connecting cylinders 602 has a worm gear ring 608 fixedly installed on its outer wall. The bottom of the outer wall of the worm gear ring 608 is meshed with a drive worm 609. Both ends of the drive worm 609 are rotatably mounted with worm arm 610. The worm arm 610 is fixedly installed on the upper surface of the positioning connecting seat 606. One end of the drive worm 609 is fixedly mounted with a driven bevel gear 611, which meshes with the drive bevel gear 612.

[0039] Two mounting slots are symmetrically opened on the body of the rotating mounting cylinder 601. A clamping electric cylinder 615 is fixedly installed inside the mounting slot. The two clamping electric cylinders 615 are symmetrically arranged and synchronously controlled by the sub-controller 607 to ensure that the axis of the steel pipe to be cut coincides with the axis of the rotating mounting cylinder 601, thereby improving the accuracy of steel pipe cutting. The clamping electric cylinder 615 is an electric hydraulic cylinder. The appropriate electric hydraulic cylinder is selected according to the actual production size of the steel pipe clamping unit 6 and the size of the steel pipe to be processed.

[0040] like Figure 1 As shown, one of the clamping electric cylinders 615 is at the bottom of the rotating mounting cylinder 601, and the other is at the top. This is the initial state of the steel pipe clamping unit 6, and the rotation angle of the rotating mounting cylinder 601 is ±200 degrees to avoid adverse effects on the wires of the clamping electric cylinder 615.

[0041] A clamping connecting frame 616 is fixedly installed at the end of the telescopic end of the clamping electric cylinder 615. A special clamping roller 617 is rotatably installed inside the clamping connecting frame 616. A V-shaped annular groove is opened on the outer wall of the special clamping roller 617, and the included angle of the V-shape is set to 160°. The two special clamping rollers 617 clamp the steel pipe to be cut, and there are four contact points at the same time to ensure the stability of the clamping of the steel pipe to be cut.

[0042] Multiple auxiliary slide rods 618 are fixedly connected to one side of the clamping connecting frame 616. The auxiliary slide rods 618 pass through the rotating mounting cylinder 601 and are slidably connected to the rotating mounting cylinder 601 through a linear bearing, which further improves the stability of the clamping connecting frame 616.

[0043] Working principle:

[0044] Reference Figures 1 to 4Assemble the device as shown in the figure;

[0045] like Figure 1 As shown, the steel pipe to be cut is conveyed by the steel pipe feeding mechanism to multiple steel pipe clamping units 6. The multiple steel pipe clamping units 6 simultaneously clamp the steel pipe to be cut. The specific process is as follows: The steel pipe to be cut enters the steel pipe clamping unit 6, falls onto multiple special-shaped clamping rollers 617 below, and after positioning, the main controller 4 simultaneously sends a "clamping" command to multiple sub-controllers 607. The sub-controllers 607 control two clamping electric cylinders 615 to extend synchronously, using the V-shaped grooves of the special-shaped clamping rollers 617 to quickly clamp and fix the steel pipe to be cut; after clamping... After completion, the main controller 4 controls the laser cutting head 3 to cut the steel pipe to be cut. At the same time, the sub-controller 607 starts the servo motor 613. The servo motor 613 controls the rotation of the drive worm 609 by meshing the drive bevel gear 612 and the driven bevel gear 611. The drive worm 609 meshes with the worm gear ring 608. The worm gear ring 608 drives the rotating mounting cylinder 601 to rotate through the positioning connecting cylinder 602. The rotating mounting cylinder 601 drives the steel pipe to be cut to rotate through the special clamping roller 617, so that the laser cutting head 3 can cut the steel pipe to be cut.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
