Description

Technical Field

[0001] This utility model relates to the field of fiber laser cutting equipment technology, and in particular to the field of support equipment for laser cutting of round tubes using fiber laser cutting equipment, specifically a round tube support device. Background Technology

[0002] Round tube processing involves cutting, bending, forming, and connecting tubes to create parts of specific shapes and sizes. Round tube laser cutting is a processing technology that uses a laser beam to cut metal round tubes with high precision and efficiency. During laser cutting, a supporting structure is needed to drive the tube to rotate, ensuring the cutting point remains at a constant position and achieving stable cutting.

[0003] A search revealed that patent application CN202021081942.4 discloses a circular tube support device, including a support assembly, a first hinge assembly, a second hinge assembly, a rotating assembly, and a base. The top surface of the support assembly has an arc-shaped cross-section, and both ends of the support assembly along its length are fixed to the first hinge assembly and the second hinge assembly, respectively. The first hinge assembly and the second hinge assembly are respectively mounted on the base. The base includes a first base plate and a second base plate, with the first base plate placed on the second base plate. The first hinge assembly and the second hinge assembly are respectively fixed to the first base plate, and the rotating assembly is connected to both the first base plate and the second base plate, allowing the first base plate and the second base plate to rotate relative to each other under the limiting position of the rotating assembly. This circular tube support device has the advantage of allowing for a relatively long transportable single section of circular tube or cylinder.

[0004] When machining round tubes, it is necessary to adjust the height of the tube to ensure that its center height is flush with the center of the chuck. Traditional tube support devices are only suitable for a few diameter specifications of round tubes, and the following problems exist:

[0005] 1. It only has a height adjustment function, and the round tube support structure is a fixed-angle "V" shape. When supporting round tubes of different diameters, the center height of the round tube is different. It is necessary to adjust the height adjustment structure to change the height of the round tube support structure, thereby changing the height of the round tube so that the center of the round tube is level with the center of the chuck.

[0006] 2. The height adjustment structure and the round tube support structure operate independently. The round tube support structure is adjustable and has a certain degree of adaptability, that is, the top angle of the "V" shaped bracket is adjustable. However, the height adjustment structure and the round tube support structure need to be adjusted at the same time to make the center of the round tube and the center of the chuck level, which is time-consuming and laborious.

[0007] Therefore, we need to propose a circular tube support device that can adapt the support structure to circular tubes of different diameters while only adjusting the height of the circular tube. Utility Model Content

[0008] The purpose of this utility model is to provide a circular tube support device. Through the design of the adjustment mechanism, rotating the handwheel, with the cooperation of the threaded rod, guide rail, and movable block, drives the two sets of diagonal bracing rods to change angle. By adjusting the X-shaped support structure, the clamping stability of different tube diameters can be achieved while changing the center height of the circular tube, so as to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a circular tube support device, comprising an aligned support base and a chuck, wherein a plurality of circular tube support mechanisms are movably arranged on the support base, and the circular tube support mechanism includes a base, wherein two sets of X-shaped diagonal braces are rotatably arranged on the side of the base, and a support roller is rotatably installed between the two sets of diagonal braces.

[0010] The bottom of the base is equipped with an adjustment mechanism that drives the diagonal brace to rotate, and the bottom of the base is also equipped with wheels for moving on the support base.

[0011] Preferably, the adjustment mechanism includes a handwheel, two bearing seats fixed to the bottom of the base, two guide rails distributed on both sides of the bearing seats, a threaded rod rotatably mounted between the two bearing seats, a rotating shaft connected to the center of the handwheel, and the rotating shaft connected to the threaded rod.

[0012] Preferably, movable block one and movable block two are respectively installed on the two slides of the guide rail, and movable block one is threadedly installed on the outer wall of the threaded rod.

[0013] Preferably, a fixed shaft is installed on the side of both movable block one and movable block two, and the two movable ends at the bottom of the diagonal brace are rotatably mounted on the outer wall of the fixed shaft one.

[0014] Preferably, the diagonal brace includes two intersecting movable plates, with a fixed shaft II passing through the two movable plates, and the two movable plates rotate around the fixed shaft II.

[0015] Preferably, the walking wheels include two walking wheels one and two walking wheels two, with the walking wheels one located at the bottom of the base near the handwheel and the walking wheels two located at the bottom of the base away from the handwheel.

[0016] Preferably, the first traveling wheel is rolled on the surface of the support base, and a hexagonal steel column is also provided on the support base, with the second traveling wheel rolled on the hexagonal steel column.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model, through the design of the adjustment mechanism, rotates the handwheel, and with the cooperation of the threaded rod, guide rail, and movable block, drives the two sets of diagonal bracing rods to change angle. By adjusting the X-shaped support structure, the clamping stability of different pipe diameters can be achieved while changing the center height of the round pipe.

[0019] 2. This utility model can not only adjust the support height of the round tube, but also adaptively adjust the angle of the V-shaped support at the top of the support structure. The operation is simple, and it can be achieved by simply turning the handwheel. There is no need to operate the two functions independently, which saves time and effort. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-5The present invention provides a technical solution: a circular tube support device, including a support base 100 and a chuck 200 aligned together. Multiple circular tube support mechanisms 300 are movably arranged on the support base 100. The circular tube support mechanism 300 includes a base 1. Two sets of X-shaped diagonal braces 2 are rotatably arranged on the side of the base 1. A support roller 3 is rotatably installed between the two sets of diagonal braces 2.

[0028] The bottom of the support base 100 is equipped with shock-absorbing legs.

[0029] By driving the two moving ends at the bottom of the X-shaped diagonal brace 2 to move towards each other, the distance between the two moving ends is changed, thereby adjusting the support height of the circular tube.

[0030] The bottom of the base 1 is equipped with an adjustment mechanism 4 that drives the diagonal brace 2 to rotate, and the bottom of the base 1 is also equipped with a traveling wheel for moving on the support base 100.

[0031] The adjustment mechanism 4 includes a handwheel 41, two bearing seats 43 fixed to the bottom of the base 1, two guide rails 47 distributed on both sides of the bearing seats 43, a threaded rod 45 rotatably mounted between the two bearing seats 43, and a rotating shaft 42 connected to the center of the handwheel 41, with the rotating shaft 42 connected to the threaded rod 45.

[0032] Rotating the handwheel 41 drives the threaded rod 45 to rotate via the shaft 42, which in turn drives the movable block 46 on the threaded rod 45 to move.

[0033] Movable block 1 46 and movable block 2 48 are respectively installed on the two slides of guide rail 47. Movable block 1 46 is threaded onto the outer wall of threaded rod 45. Movable block 1 46 and movable block 2 48 move towards each other.

[0034] Each guide rail 47 is provided with two slides. Movable block 1 46 is connected to the two slides of one guide rail 47, and movable block 2 48 is installed on the two slides of the other guide rail 47.

[0035] Both movable block 46 and movable block 48 are equipped with fixed shaft 21 on their sides, and the two movable ends at the bottom of the diagonal brace 2 are rotatably mounted on the outer wall of fixed shaft 21.

[0036] When movable block 46 moves, it drives movable block 48 to move through the cooperation of diagonal brace 2, thereby enabling the two movable ends at the bottom of diagonal brace 2 to move towards each other, which can change the shape of diagonal brace 2 and realize the height adjustment of the circular tube.

[0037] The diagonal brace 2 includes two intersecting movable plates, with a fixed shaft 22 running through them. The two movable plates rotate around the fixed shaft 22. When adjusting the diagonal brace 2, the fixed shaft 22 moves up and down in the vertical direction.

[0038] The traveling wheels include two traveling wheels 5 and two traveling wheels 6. The traveling wheels 5 are located at the bottom of the base 1 near the handwheel 41, and the traveling wheels 6 are located at the bottom of the base 1 away from the handwheel 41.

[0039] The first traveling wheel 5 is rolled on the surface of the support base 100. A hexagonal steel column 400 is also installed on the support base 100. The second traveling wheel 6 is rolled on the hexagonal steel column 400 to ensure the stability of the movement of the circular tube support mechanism 300.

[0040] When using this device to support a round tube for laser cutting, place the round tube on the round tube support mechanism 300 and adjust the height of the round tube so that its center is aligned with the center of the chuck 200. Specifically, rotate the handwheel 41, which drives the threaded rod 45 to rotate through the rotating shaft 42. The threaded rod 45 drives the movable block 1 46 to move on the guide rail 47. With the cooperation of the two sets of diagonal braces 2, it also drives the movable block 2 48 to move on the guide rail 47. The movable block 1 46 and the movable block 2 48 move towards each other. Due to the change in the distance between the two bottom ends of the diagonal brace 2, the diagonal brace 2 is driven to rotate and deform, that is, the included angle between the two movable plates in the diagonal brace 2 changes, which can lift or lower the round tube (for large-diameter round tubes, the support height decreases, and for small-diameter round tubes, the support height increases).

[0041] Then, one end of the round tube is inserted into the chuck 200, and the round tube is driven to rotate by the chuck 200. With the cooperation of the laser cutting structure (not shown in the figure), the round tube is cut.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
