Description

Technical Field

[0001] The utility model relates to the field of C-shaped steel, and more specifically, to a double-joined automatic welding production line for C-shaped steel. Background Art

[0002] C-shaped steels are all automatically processed and formed by a C-shaped steel forming machine. The C-shaped steel forming machine can automatically complete the forming process of C-shaped steel according to the given C-shaped steel dimensions. C-shaped steels are widely used for purlins and wall beams of steel structure buildings, and can also be self-assembled into lightweight roof trusses, brackets and other building components. In addition, they can also be used for columns, beams, arms, etc. in mechanical and light industrial manufacturing.

[0003] In the actual application process of building construction, C-shaped steels are usually used. And in some special cases, two C-shaped steels are double-joined and welded for use. For example, Chinese Patent CN 221110400U discloses a double-joined automatic welding production line for C-shaped steel, including a U-shaped placement table and a round rod. The upper end of the U-shaped placement table is fixedly provided with a U-shaped operation table. An arc-shaped groove is opened on the side wall of the U-shaped placement table. A cross plate is movably arranged on the upper end of the U-shaped placement table. A threaded rod is movably arranged inside the arc-shaped groove. One side of the cross plate is fixedly provided with a first ring. One end of the first ring is fixedly provided with a telescopic rod. The other end of the telescopic rod is fixedly provided with a second ring. A groove is opened on the inner wall of the U-shaped placement table. Through the above technical solution, the problem that it is not convenient to stably double-join and weld C-shaped steel in the prior art is solved.

[0004] Although the above double-joined automatic welding production line for C-shaped steel can ensure the stability between two C-shaped steels during the welding process through structural design to ensure the welding effect, it is found in the actual application process that since the threaded rotary shaft needs to be rotated when placing both C-shaped steels, and then the cross plate is moved to place the C-shaped steels. Similarly, after placement, the threaded rotary shaft needs to be rotated again to move the cross plate to take out the double-joined C-shaped steel after welding. Such frequent operations result in low efficiency during the actual welding process. Therefore, it is particularly important to propose a production line that can quickly fix the double-joined C-shaped steel. Therefore, we make improvements on this and propose a double-joined automatic welding production line for C-shaped steel. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a double-joined automatic welding production line for C-shaped steel, which solves the problem that the existing double-joined automatic welding production line for C-shaped steel can quickly fix the double-joined C-shaped steel when in use.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0007] A double - spliced automatic welding production line for C - shaped steel, which includes:

[0008] A bearing seat, which has two sets of sliding grooves symmetrically distributed on both sides of the surface of the bearing seat;

[0009] A sliding plate, which is slidably assembled on the bearing seat through the sliding grooves for the assembly of positioning elements;

[0010] There are four positioning elements. Two of the positioning elements on the same sliding plate are in a group. A locking element is commonly installed on the surfaces of the two positioning elements in each group;

[0011] Among them, the positioning element includes a positioning cylinder, an assembly seat connected to the end of the positioning cylinder, and a ball movably embedded in the assembly seat.

[0014] As a preferred technical solution of the present application, the locking element includes a connecting plate and transmission rods distributed at both ends of the connecting plate;

[0015] Among them, a check seat is slidably arranged on one side of the assembly seat close to the ball. One end of the transmission rod penetrates through the positioning cylinder and extends into the assembly seat to be fixed to the check seat.

[0016] As a preferred technical solution of the present application, a check groove adapted to the ball is opened on one side of the check seat close to the ball.

[0017] As a preferred technical solution of the present application, an adjusting screw rod is threadedly penetrated through the connecting plate, and one end of the adjusting screw rod is movably assembled on the sliding plate;

[0018] Rotate the adjusting screw rod so that one end of its check seat abuts against the ball to form a brake.

[0023] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0024] In the solution of the present application:

[0025] 1. By providing positioning elements and locking elements, when double-welding two C-shaped steels, the size of the positioning space between the balls on the two positioning elements can be adjusted first to make the size of the positioning space consistent with the inner wall thickness sum of the two C-shaped steels. Then, during the actual welding and fixing operation, the two C-shaped steels can be directly inserted into the positioning space and guided by the balls to achieve quick fixing. The position adjustment in the length direction of the two C-shaped steels can be realized through the balls. Finally, the locking element is selected to lock the balls to complete the fixing operation. Compared with the traditional C-shaped steel double-welding production line, the time required for operation is greatly reduced, which is beneficial to improving the welding efficiency.

[0026] 2. By providing positioning elements, when dealing with C-shaped steels of different thickness dimensions, the size of the positioning space can be adjusted in advance. In this way, during the flow-line operation welding, only by rotating the locking element for locking and unlocking can the positioning be quickly and effectively completed.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some but not all of the embodiments of the present utility model.

[0039] As Figures 1 - 6 shown, this implementation manner provides a double-spliced automatic welding production line for C-shaped steel, which includes: a bearing seat 1 having two sets of sliding grooves 11 symmetrically distributed on both sides of the surface of the bearing seat 1; a sliding plate 2 slidably assembled on the bearing seat 1 through the sliding grooves 11 for the assembly of positioning elements 3; there are four positioning elements 3, and two positioning elements 3 on the same sliding plate 2 are a group. Locking elements 4 are commonly installed on the surfaces of the two positioning elements 3 in each group. Among them, the positioning element 3 includes a positioning cylinder 31, an assembly seat 32 connected to the end of the positioning cylinder 31, and balls 33 movably embedded in the assembly seat 32;

[0040] The bearing seat 1 has an extension platform 12, and a locking bolt 13 is threadedly assembled on the surface of the extension platform 12;

[0041] The positioning element 3 is fixed to the sliding plate 2 through the positioning cylinder 31;

[0042] A positioning space 34 is commonly formed at the ends of the two groups of positioning elements 3;

[0043] Two C-shaped steels are distributed in the positioning space 34;

[0044] When actually performing the splicing and welding operation on two C-shaped steels, the size of the positioning space 34 can be adjusted according to the thickness of the inner walls of the two C-shaped steels, so that the size of the positioning space 34 is adapted to the thickness of the C-shaped steel. In this way, when inserting and welding the C-shaped steel, the C-shaped steel can be directly slid into the positioning space 34 through the balls 33 to quickly achieve preliminary positioning. The specific steps are as follows:

[0045] Move the sliding plate 2 on the bearing seat 1. During the movement of the sliding plate 2, the balls 33 in the positioning element 3 thereon will move synchronously. In this way, the size of the positioning space 34 between the two groups of balls 33 on the two sliding plates 2 will be adjusted synchronously. Finally, after adjusting to match the thickness of the C-shaped steel, the locking bolt 13 can be rotated so that one end thereof abuts against the bearing seat 1 to form a limiting effect on the sliding plate 2;

[0046] Since the thickness of each batch of processed C-shaped steel is of the same model, in the actual welding operation process, only need to adjust the positioning space 34 once, and then there is no need to adjust it later to carry out positioning, thus greatly improving the efficiency of welding and fixing the C-shaped steel;

[0047] The locking element 4 includes a connecting plate 41 and transmission rods 42 distributed at both ends of the connecting plate 41. A check seat 44 is slidably arranged on one side of the assembly seat 32 close to the ball 33. One end of the transmission rod 42 penetrates through the positioning cylinder 31 and extends into the assembly seat 32 to be fixed to the check seat 44;

[0048] A check groove 45 adapted to the ball 33 is opened on one side of the check seat 44 close to the ball 33;

[0049] An adjusting screw rod 46 is threadedly penetrated through the connecting plate 41. One end of the adjusting screw rod 46 is movably assembled on the sliding plate 2. The adjusting screw rod 46 makes one end of the check seat 44 abut against the ball 33 to form braking;

[0050] In the above operation, after the two C-shaped steels to be welded are poured into the positioning space 34 through the balls 33 in the movable state to form preliminary positioning, at this time, the adjusting screw rod 46 can be directly rotated to form a threaded fit with the connecting plate 41. The connecting plate 41 driven by the thread will make the transmission rod 42 thereon and the check seat 44 at its end slide towards the direction of the ball 33, so that the check seat 44 abuts against the surface of the ball 33, thereby forming positioning for the ball 33;

[0051] In this way, when the ball 33 cannot rotate under the check action, the C-shaped steel in the positioning space 34 is relatively positioned and fixed, thus ensuring the stability during the welding process. After the subsequent welding is completed, only need to rotate the adjusting screw rod 46 in the reverse direction to release the limit on the ball 33, and directly take out the welded double-piece C-shaped steel from the positioning space 34;

[0052] As a further optimization of this embodiment: a rubber anti-slip cushion layer 47 is laid in the check groove 45;

[0053] Such as Figure 3 and Figure 4As shown, under the action of the rubber anti-slip cushion layer 47, the friction force during the check process of the check seat 44 against the ball 33 is increased, thereby ensuring the check effect on the ball 33.

[0054] A support frame 14 is fixed to the outside of the bearing seat 1, and a welding assembly 15 is installed at the top of the support frame 14. As Figure 6 shown, the welding assembly 15 designed in this embodiment is a mature and perfect existing technology, so no further elaboration is made. The fixed C-shaped steel can be welded through the welding assembly 15.

[0055] The above embodiments are only used to illustrate the present invention and do not limit the technical solutions described in the present invention. Although this specification has described the present invention in detail with reference to the above respective embodiments, the present invention is not limited to the above specific implementation manners. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and their improvements that do not depart from the spirit and scope of the invention are covered by the scope of the claims of the present invention.
