Movable driving material supporting structure

Abstract

A movable driving material supporting structure comprises a seat body and a material supporting mechanism. The seat body comprises two guide rail frames and a guide rail; the material supporting mechanism comprises two transverse sliding rails arranged in a crossing mode, a pair of vertical guide rails, a lifting frame, a lifting pushing piece, a clamp arranged on the lifting frame and an opening and closing pushing piece used for pushing the clamp to be opened and closed. When the end, close to the chuck, of the supported pipe is obviously higher or lower due to the camber of the material, and the chuck cannot clamp the pipe stably or cannot clamp the pipe stably, the material supporting mechanism can slide for a small section along the guide rail manually (or systematically arranged) to be slightly lowered or lifted, so that the chuck can clamp the pipe; when the lengths of the pipes to be cut are different, the material supporting mechanism can slide for a small section along the guide rail manually (or systematically set), so that the material supporting mechanism is moved to a position with a proper distance from the chuck, and therefore, the material supporting mechanism is favorable for improving the clamping efficiency and precision of the chuck, and is suitable for laser pipe cutting machines with different lengths of pipes.

Description

Technical Field

[0001] The utility model relates to a laser pipe cutting machine, in particular to a material supporting mechanism on the laser pipe cutting machine. Background Art

[0002] After the material supporting mechanism of the laser pipe cutting machine lifts the pipe, the chuck clamps the pipe. Then, the moving mechanism pushes the chuck with the clamped pipe towards the cutting mechanism for a certain distance, and then the cutting mechanism cuts out the pipe with the required length.

[0003] Since the current material supporting mechanism of the pipe cutting machine is fixed at a certain position of the machine, and the pipes to be cut are relatively long, it is difficult for such long pipes to be straight and without curvature for each one. Moreover, some pipes are slightly longer and some are slightly shorter. Therefore, it is difficult to ensure that the ends of each pipe can accurately align with the center of the chuck when lifted by the material supporting mechanism that is always in the same position. For pipes with a large deviation from the center of the chuck, external force assistance by manual is often required for correction, which to a certain extent affects the clamping efficiency of the chuck and increases the labor intensity of workers. Summary of the Invention

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a movable driving material supporting structure, which helps to improve the clamping efficiency and accuracy of the chuck and is applicable to the laser pipe cutting machine with different pipe lengths.

[0005] In order to solve the above existing technical problems, the utility model adopts the following technical solutions:

[0006] A movable driving material supporting structure includes a base body and a material supporting mechanism, wherein:

[0007] The base body is installed and fixed to the bottom of the laser pipe cutting machine, and it includes two guide rail frames arranged along the moving direction of the chuck of the pipe cutting machine and guide rails provided on the guide rail frames;

[0008] The material supporting mechanism includes a horizontal sliding rail spanning across the two guide rails, a pair of vertical guide rails provided on the horizontal sliding rail, a lifting frame arranged between the pair of vertical guide rails and capable of lifting along the vertical guide rails, a lifting pushing member provided on the horizontal sliding rail for pushing and pulling the lifting frame, and a clamp provided on the lifting frame and an opening and closing pushing member for pushing the clamp to open and close.

[0009] In an improved solution for the above-mentioned movable driving and supporting structure, the lifting and pushing member is a lifting cylinder. The fixture includes a pair of swing arms with one end swing-connected to the lifting frame and the other end provided with clamping arms; a pair of synchronous teeth are provided at the swinging ends of the pair of swing arms; the opening and closing pushing member includes an opening and closing cylinder and a rack driven by the opening and closing cylinder to expand and contract; the driving teeth on both sides of the rack are respectively engaged with the synchronous teeth of the pair of swing arms.

[0010] In an improved solution for the above-mentioned movable driving and supporting structure, the clamping arm includes an arm shaft and a roller rotatably sleeved outside the arm shaft; the arm shaft is detachably installed on the swing arm.

[0011] In an improved solution for the above-mentioned movable driving and supporting structure, a supporting roller is provided on the upper part of the lifting frame, and both ends of its roller shaft are fixed to the lifting frame through roller arms; the supporting roller is located at the bottom of the clamping arm in terms of height.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: Since the supporting mechanism is slidably installed on the slide rail of the seat body, in this way, when the end of the pipe lifted up is significantly higher or lower due to the curvature of the material, resulting in the chuck being unable to clamp or hold the pipe firmly, it can be adjusted slightly by manually (or system setting) making the supporting mechanism slide a short distance along the guide rail to slightly lower or lift it, so that the chuck can clamp the pipe; when the lengths of the pipes to be cut are different, it can also be adjusted by manually (or system setting) making the supporting mechanism slide a short distance along the guide rail, so that the supporting mechanism moves to a position with a suitable distance from the chuck. Therefore, the present utility model helps to improve the chuck clamping efficiency and accuracy and is applicable to laser pipe cutting machines with different pipe lengths.

[0013] The following further describes the present utility model in detail in conjunction with the drawings and specific embodiments: Description of the Drawings

[0018] The present utility model is a movable driving and supporting structure, asFigures 1 to 4 As shown in the figure, it includes a base body 1 and a material supporting mechanism 2, where:

[0019] The base body 1 is installed and fixed to the bottom of the laser pipe cutting machine, and it includes two guide rail frames 11 arranged along the moving direction of the chuck of the pipe cutting machine and guide rails 12 provided on the guide rail frames 11;

[0020] The material supporting mechanism 2 includes a transverse slide rail 21 spanning and arranged on the two guide rails 12, a pair of vertical guide rails 22 provided on the transverse slide rail 21, a lifting frame 23 arranged between the pair of vertical guide rails 22 and capable of lifting along the vertical guide rails 22, a lifting driving member 24 provided on the transverse slide rail 21 for pushing and pulling the lifting frame 23, a clamp 25 provided on the lifting frame 23, and an opening and closing driving member 26 for pushing the clamp 25 to open and close.

[0021] When the utility model is working, after the opening and closing driving member 26 makes the clamp 25 clamp the pipe, the lifting driving member 24 raises the lifting frame 23 to align the end of the pipe with the chuck of the pipe cutting machine; when the chuck of the pipe cutting machine clamps the pipe, after the lifting driving member 24 and the opening and closing driving member 26 drive their respective components to return to their positions, the material supporting mechanism 2 completes one material supporting process and waits for the instruction of the pipe cutting machine to perform the material supporting of the next pipe. When it is found that the end of the pipe that is supported and leans towards the chuck is too high or too low due to the curvature of the material, resulting in the chuck being unable to clamp, clamp stably, or hold the pipe firmly, the material supporting mechanism 2 can be made to slide a short distance along the guide rail 12 (i.e., fine adjustment movement) manually (or through system settings, because the laser pipe cutting machine completes the parameter settings through the manual operation system program) to slightly lower or raise the pipe, so that the chuck can clamp the pipe, thereby helping to improve the clamping efficiency and accuracy of the chuck. When the lengths of the pipes to be cut are different, the material supporting mechanism can also be made to slide a short distance along the guide rail manually (or through the system settings of the laser pipe cutting machine, using a device capable of pushing the transverse slide rail to move to translate the entire material supporting mechanism) to move the material supporting mechanism to a position with a suitable distance from the chuck, so as to improve the applicable range of the laser pipe cutting machine to cut pipes of different lengths.

[0022] In this embodiment, as Figure 3 、 4As shown, the lifting and pushing member 24 is a lifting cylinder. The fixture 25 includes a pair of swing arms 252, one end of which is swingably connected to the lifting frame 23 and the other end is provided with clamping arms 251; a pair of synchronous teeth 2521 are provided at the swing ends of the pair of swing arms 252; the opening and closing pushing member 26 includes an opening and closing cylinder 261 and a rack 262 driven by the opening and closing cylinder 261 to expand and contract; the driving teeth 2621 on both sides of the rack 262 are respectively engaged with the synchronous teeth 2521 of the pair of swing arms 252, so that it can be ensured that the pair of swing arms 252 open and close simultaneously to improve the reliability and stability of clamping the pipe. Preferably, the clamping arm 251 includes an arm shaft 2511 and a roller 2512 rotatably sleeved outside the arm shaft 2511; the arm shaft 2511 is detachably mounted on the swing arm 252, which is convenient for replacing and maintaining the clamping arm and can also improve the service life of the clamping arm.

[0023] In this embodiment, a material supporting roller 27 is provided on the upper part of the lifting frame 23, and both ends of its roller shaft 271 are fixed to the lifting frame 23 through roller arms 272, so that there is no need to support the material on the upper surface of the lifting frame. The material supporting roller 27, as a vulnerable part, is very convenient for replacement and maintenance; the material supporting roller 27 is located at the bottom of the clamping arm 251 in terms of height.
