Description

Technical Field

[0001] This utility model belongs to the technical field of integrated plate and tube laser cutting machine, and particularly relates to a tube support mechanism for an integrated plate and tube fully enclosed laser cutting machine. Background Technology

[0002] In the industrial processing field, the integrated sheet and tube laser cutting machine, as an integrated and efficient processing equipment, effectively reduces the equipment investment costs, space occupation, and process changeover time associated with traditional separate sheet and tube cutting machines. It is widely used in various industries such as metal structure manufacturing, hardware processing, medical devices, and furniture manufacturing. This type of equipment typically consists of a sheet cutting bed, a tube cutting bed, a crossbeam that can move across the beds, and a laser cutting head. To improve processing safety and prevent the spread of cutting dust and laser radiation leakage, a full-enclosed cover is installed on the outside of the equipment, further optimizing the processing environment and operational safety.

[0003] To achieve integrated adaptation for sheet and tube processing, the tube cutting machine of the integrated sheet and tube laser cutting machine needs to be structurally coordinated with the sheet cutting machine. Its length is often extended according to the size of the sheet cutting machine to ensure that the crossbeam can be stably mounted and that the cutting head can be smoothly switched between the sheet and tube processing areas. However, this extension in length means that when the tube cutting machine is dealing with the processing of longer tubes, it is difficult to meet the stable processing requirements by relying solely on the fixed clamping chucks at both ends of the tube cutting bed and the tail clamping chuck for positioning and support. Under its own weight, the longer tube is prone to sag deformation in the middle area between the two end chucks. This not only causes the tube axis to deviate from the preset processing trajectory, resulting in reduced cutting accuracy, but also causes problems such as skewed cuts and dimensional deviations.

[0004] To address the aforementioned issues, some existing integrated plate and tube laser cutting machines have begun to incorporate tube support mechanisms in their tube cutting sections to provide auxiliary support for the middle section of longer tubes. However, these existing tube support mechanisms still have significant shortcomings in practical applications. One prominent problem is the poor flexibility in adjusting the support height, making it difficult to adapt to the stable support processing requirements of tubes with different diameters. Specifically, most existing tube support mechanisms use a cylinder-driven "V"-shaped support structure. While this can provide some support for tubes of different diameters, the tubes experience significant swaying during operation, making it difficult to fully leverage the high-efficiency processing advantages of integrated plate and tube laser cutting machines. Utility Model Content

[0005] The purpose of this invention is to provide a pipe support mechanism for a plate-and-tube integrated full-enclosed laser cutting machine, which, although adaptable to pipes of certain diameters, suffers from strong wobbling during pipe processing.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: a tube support mechanism for a plate and tube integrated full-enclosure laser cutting machine, comprising a plate cutting bed and a tube cutting bed arranged in a mutually matched manner, a crossbeam driven between the plate cutting beds, the crossbeam extending above the tube cutting bed, a laser cutting head driven on the crossbeam, a full-enclosure cover provided on the outer sides of the plate cutting bed and the tube cutting bed, a fixed clamping chuck provided at one end of the upper surface of the tube cutting bed, and a tail clamping chuck driven at the other end, and a plurality of tube support mechanisms evenly distributed in the cavity of the tube cutting bed, the plurality of tube support mechanisms cooperating with the fixed clamping chuck and the tail clamping chuck;

[0007] The pipe support mechanism includes a support base plate fixed to the bottom of the pipe cutting bed cavity. Two sets of support arms are arranged opposite each other on the upper surface of the support base plate. A follower arm is rotatably arranged between the two sets of support arms. A linkage is rotatably arranged on the follower arm. A drive cylinder is arranged on the upper surface of the support base plate between the two sets of support arms. A drive component is arranged on the telescopic rod of the drive cylinder. The drive component is rotatably connected to the linkage. A support roller is rotatably arranged at the end of the follower arm. A variable diameter groove is opened on the support roller. A locking base plate is arranged on the outer wall of the follower arm located at the support roller. A locking pin is arranged on the locking base plate. A plurality of locking holes that cooperate with the locking pin are evenly distributed along the circumference of the outer wall of the support roller.

[0008] Furthermore, the full enclosure includes a frame welded from rectangular steel pipes, with panels arranged inside the frame. One end of the frame has an opening and closing inspection door, and a control host is located on one side of the inspection door. Observation windows are opened on the panels on both sides of the frame, and several exhaust fans are installed on the panel at the top of the frame.

[0009] Furthermore, the support arm and the upper surface of the supporting base plate are integrally formed, and the follower arm is rotatably connected to the support arm through a first pin.

[0010] Furthermore, the cylinder body of the driving cylinder is fixedly connected to the supporting base plate through a cylinder base, and the telescopic rod of the driving cylinder is connected to the driving component through a thread. The connection between the two is provided with a locking nut, which is a double-nut anti-loosening structure.

[0011] Furthermore, the driving component has a U-shaped structure. One end of the linkage component is rotatably connected to the follower arm via a second pin, and the other end is rotatably connected to the driving component via a third pin to both end walls of the U-shaped structure. Anti-disengagement snap rings are provided at the component mating points of the second pin and the third pin.

[0012] Furthermore, the variable diameter groove on the support roller is an arc-shaped groove, and the depth of the variable diameter groove gradually changes along the circumferential direction of the support roller.

[0013] Furthermore, groove depth markings are provided on the outer wall of each of the support rollers located at each of the locking holes.

[0014] Beneficial effects: This utility model has a reasonable design, simple and stable structure, and strong practicality, and has the following beneficial effects:

[0015] 1. Solve the problem of sagging deformation of long pipes and improve cutting accuracy: By evenly setting multiple sets of pipe support mechanisms in the pipe cutting bed cavity, which cooperate with the fixed clamping chucks at both ends and the tail end clamping chuck to provide stable support for the middle area of ​​long pipes, the sagging deformation of the pipes due to their own weight can be effectively avoided, ensuring that the pipe axis is consistent with the preset processing trajectory, reducing problems such as cut tilt and dimensional deviation, and significantly improving the pipe cutting accuracy;

[0016] 2. Flexible support height adjustment, suitable for processing multiple diameter pipes: The pipe support mechanism drives the telescopic rod to extend and retract through the drive cylinder, which in turn drives the drive components and linkage components to rotate around the support arm, thereby realizing flexible adjustment of the support roller height. Combined with the variable diameter groove on the support roller, which gradually changes the depth along the circumference, it can adapt to the placement requirements of pipes of different diameter specifications without disassembling or replacing parts, reducing the complexity of operation and improving the adaptability and efficiency of processing multiple specifications of pipes.

[0017] 3. Stable positioning of the support roller reduces pipe sway during processing: The outer wall of the follower arm is equipped with locking pins through the locking base plate, and the outer wall of the support roller is equipped with multiple sets of locking holes. After adjusting the angle of the support roller, the locking pins are inserted into the corresponding locking holes to achieve stable positioning of the support roller. At the same time, the arc-shaped structure of the variable diameter groove can form a ring-shaped support for the pipe, effectively reducing the swaying sensation during pipe processing and further ensuring processing stability and safety.

Detailed Implementation

[0023] 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.

[0024] Example 1:

[0025] Combination Figure 1-3 The tube support mechanism shown is for a fully enclosed laser cutting machine for integrated sheet and tube cutting. It aims to achieve efficient integrated cutting of sheet metal and tubes, and ensures the stability of tube processing through precise support. Its overall structure and working relationship are as follows:

[0026] The system includes a sheet metal cutting bed 1 and a pipe cutting bed 2, arranged in a coordinated layout. The sheet metal cutting bed 1 serves as the basic carrier for sheet metal processing, with a crossbeam 3 driven between its top two sides. The crossbeam 3 reciprocates along the length of the sheet metal cutting bed 1 via a guide rail slider mechanism, and one end of the crossbeam 3 extends directly above the pipe cutting bed 2, forming a processing coverage area across the bed. A laser cutting head 4 is driven by another set of drive components (such as a servo motor and ball screw) on the crossbeam 3. The laser cutting head 4 can move along the length of the crossbeam 3, ultimately achieving full-area movement of the laser cutting head 4 above both the sheet metal cutting bed 1 and the pipe cutting bed 2, meeting the cutting needs of different positions of the sheet metal and pipe. To ensure processing safety and environmental cleanliness, the outer sides of both the sheet metal cutting bed 1 and the pipe cutting bed 2 are completely covered by a full-enclosure cover 5. The full-enclosure cover 5 confines the dust, sparks, and laser radiation generated during the cutting process within a closed space, preventing pollution to the external environment. To address the impact on operators, and in response to pipe cutting needs, a fixed clamping chuck 6 is fixedly installed at one end of the upper surface of the pipe cutting bed 2. This chuck serves as a fixed reference end for the pipe, clamping one end of the pipe with jaws and achieving circumferential positioning. Meanwhile, a tail-end clamping chuck 7 is driven and installed at the other end of the upper surface of the pipe cutting bed 2. The tail-end clamping chuck 7 can move along the length of the pipe cutting bed 2 via a linear drive mechanism (such as rack and pinion transmission) on the bed, thus adapting to clamping pipes of different lengths. To meet the requirements, the fixed clamping chuck 6 and the tail clamping chuck 7 work together to position and clamp the two ends of the pipe. Considering that long pipes are prone to sagging due to their own weight if they are only clamped by the two end chucks, several sets of pipe support mechanisms 8 are evenly distributed along the length of the pipe cutting bed 2. The several sets of pipe support mechanisms 8, together with the fixed clamping chuck 6 and the tail clamping chuck 7, form a coordinated support relationship of "clamping at both ends + multi-point support in the middle", ensuring that the pipe always keeps its axis straight during the processing.

[0027] Specifically, regarding the structure and operation of the pipe support mechanism 8: It has a support base plate 801 at its bottom. The support plate 801 is bolted to the bottom of the pipe cutting bed 2 cavity, providing a stable support foundation for the entire support mechanism. Two sets of support arms 802 are arranged opposite each other on the upper surface of the support base plate 801. The two sets of support arms 802 have a symmetrical vertical structure, and a follower arm 803 is rotatably connected between them. A linkage 804 is rotatably installed at the middle of the follower arm 803. A drive cylinder 805 is fixedly installed on the upper surface of the support base plate 801 between the two sets of support arms 802. A drive element 806 is fixedly installed at the end of the extension rod of the drive cylinder 805. The drive element 806 is rotatably connected to the end of the linkage 804 away from the follower arm 803, forming a transmission relationship of "drive cylinder - drive element - linkage element - follower arm". When the extension rod of the drive cylinder 805 extends, it pushes the drive element 806 forward. The drive element 806 drives the linkage 804 to rotate, which in turn pushes the follower arm 803 to rotate around the point of rotation, thereby increasing the support height. As the support height decreases, a support roller 807 is rotatably mounted on the end of the follower arm 803 away from the support arm 802. A variable diameter groove 808 is formed on the outer circumference of the support roller 807. Depending on the pipe diameter, the support roller 807 can be rotated to make the corresponding groove depth of the variable diameter groove 808 fit against the pipe, achieving adaptive support for pipes of different diameters. To fix the angle of the support roller 807, a locking base plate 80 is bolted to the outer wall of the follower arm 803 on one side of the support roller 807. 9. A locking pin 8010 is slidably provided on the locking base plate 809. The locking pin 8010 can move along the axial direction of the locking base plate 809. At the same time, a number of locking holes 8011 are evenly distributed on the outer side wall of the support roller 807 along its circumference. When the support roller 807 rotates to the target angle, the locking pin 8010 is inserted into the corresponding locking hole 8011 to lock the angle of the support roller 807, thus preventing the support roller 807 from rotating on its own during the processing and causing the pipe support to shift.

[0028] In this embodiment, the full-coverage cover 5 serves as the core protection and operating carrier of the integrated plate and tube laser cutting machine. Its structural design revolves around four core requirements: stable support, comprehensive protection, convenient operation, and environmental optimization. The working principles and coordination relationships of each component are as follows: The basic support structure of the full-coverage cover 5 is a frame 501, which is formed by welding rectangular steel pipes. Panels 502 are evenly distributed on the inner side of the frame 501. One end of the enclosure is equipped with an openable maintenance door 503, designed to facilitate operator access for equipment maintenance. A control host 504 is fixedly mounted on the frame 501 on one side of the maintenance door 503. The installation height of the control host 504 is at the operator's line of sight. The operator can set cutting parameters (such as pipe diameter and cutting speed) and monitor the equipment's operating status (such as support mechanism height and exhaust fan speed) in real time through the touch screen of the control host 504. Observation windows 505 are provided on the panels 502 on both sides of the frame 501. The inner side of the observation windows 505 is inlaid with double-layered laminated glass, designed to allow the operator to observe the cutting process in real time without opening the maintenance door. Several exhaust fans 506 are evenly arranged on the panel 502 at the top of the frame 501 to create a negative pressure environment inside the enclosure, which carries the metal dust and harmful gases generated during the cutting process to the air duct.

[0029] In this embodiment, in the structural design of the pipe support mechanism, the support arm 802 and the upper surface of the support base plate 801 adopt an integral molding structure. The follower arm 803 is rotatably connected to the support arm 802 through the first pin, so as to realize the flexible rotation of the follower arm 803 around the support arm 802, while ensuring the connection strength.

[0030] In this embodiment, in the power transmission system of the pipe support mechanism, the drive cylinder 805 serves as the core power source. Its cylinder body is fixedly connected to the support base plate 801 through a cylinder base, ensuring precise guidance of the linear movement of the extension rod of the drive cylinder 805. The extension rod of the drive cylinder 805 and the drive component 806 are connected by threads. To prevent the threaded connection between the extension rod and the drive component 806 from loosening due to vibration during long-term operation of the drive cylinder 805, a locking nut is specially provided at the connection point. The locking nut adopts a double-nut anti-loosening structure to ensure that the connection between the extension rod and the drive component 806 remains stable at all times, avoiding jamming or failure of the support mechanism due to loose connection.

[0031] In this embodiment, the drive component 806 adopts a U-shaped structure design. The linkage component 804 is a key transmission component connecting the follower arm 803 and the drive component 806. Its two ends are rotatably connected by the second pin and the third pin, respectively, forming a flexible transmission link of "follower arm-linkage component-drive component". In order to prevent the component from axial displacement due to vibration and impact during long-term rotation, anti-disengagement snap rings are provided at the component mating points of the two types of pins.

[0032] In this embodiment, the variable diameter groove 808 opened on the support roller 807 adopts an arc-shaped groove structure. More importantly, the groove depth of the variable diameter groove 808 gradually changes in gradient along the circumferential direction of the support roller 807. This design aims to adapt to pipes of different diameters through the "single roller with multiple groove depths" structure, so as to meet diverse processing needs without frequent replacement of the support roller.

[0033] In this embodiment, in the structural design of the support roller 807 of the pipe support mechanism, for each group of locking holes 8011, a groove depth mark is set on the outer side wall of the support roller 807. The core logic of this mark design is to establish an intuitive correspondence between "locking hole position - groove depth parameter", providing visual guidance for operators to quickly and accurately adjust the angle of the support roller, avoiding support adaptation deviation due to misjudgment of groove depth, providing reliable operational guarantee for stable support of pipes of different diameters, and further improving the adaptability and practicality of the entire pipe support mechanism 8.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

This narrative style is merely for clarity.
