[0004] However, when the above device limits the steel bars, two arc-shaped limiting plates are used. When welding the connection of two steel bars, the steel bars need to be welded around the connection. This device may cause difficulties in rotating the steel bars, thus bringing difficulties to the welding work. At the same time, in this case, the connection may not be completely welded, resulting in insufficient welding firmness. In addition, the firm limitation of the steel bars by the circular limiting plates will cause difficulties in pulling the steel bars during welding, and further make it difficult to position the two steel bars.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will refer to the drawings and combine with the embodiments to elaborate on this application in detail.

[0028] To enable those skilled in the art to better understand the solution of this application, the following will clearly and completely describe the technical solution in the embodiments of this application in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

[0029] As Figures 1-5 shown, this application provides a steel bar welding machine with quick positioning, including a base 1; an operating table 3 is fixedly connected to the base 1, a welding mechanism 6 is fixedly connected to the operating table 3, the welding mechanism 6 is located at the center of the operating table 3, and four universal wheels 2 are fixedly connected to one side of the base 1 away from the operating table 3.

[0030] As Figure 5 shown, a limiting mechanism 5 is arranged on the base 1. The limiting mechanism 5 includes a threaded rod 53 threaded through the base 1. The lower end of the threaded rod 53 is rotatably connected to a limiting plate 54. A plurality of barbs 55 are fixedly connected to the lower end of the limiting plate 54. The plurality of barbs 55 are evenly distributed below the limiting plate 54. Four limiting rods 56 are symmetrically slidably connected to the surface of the base 1. The four limiting rods 56 are divided into two groups in pairs, and each group of limiting rods 56 is fixedly connected to the limiting plate 54. One end of the threaded rod 53 away from the limiting plate 54 is fixedly connected to a rotating block 51, and a handle 52 is rotatably connected to the rotating block 51. The handle 52 can facilitate the personnel to rotate the threaded rod 53.

[0031] By rotating the threaded rod 53, the threaded rod 53 will drive the limiting plate 54 to move in the vertical direction by the internal wall thread of the base 1. When the limiting plate 54 moves to a suitable position, the limiting plate 54 will limit the whole device to prevent the device from self-moving due to shaking. At the same time, the barbs 55 can increase the friction between the limiting plate 54 and the ground, further improving the limiting performance of the limiting plate 54.

[0032] As Figures 2-4 shown, a positioning mechanism 4 is arranged on the operating table 3. The positioning mechanism 4 includes a connecting plate 402 fixedly connected to one side of the base 1. A motor 401 is fixedly connected to the connecting plate 402. The output end of the motor 401 is fixedly connected to a bolt rod a 409. A moving groove 411 is opened on the operating table 3. Two clamping columns 410 are slidably connected to the inner wall of the moving groove 411. A moving frame 408 is fixedly connected to the surface of the clamping column 410. The two moving frames 408 are threadedly connected to the bolt rod a 409. A semi-circular block a is fixedly connected to the moving frame 408. A semi-circular block b 406 is arranged on the semi-circular block a 407.

[0033] Meanwhile, a connecting frame 403 is fixedly connected to the moving frame 408. A bolt rod b404 is threadedly connected to the inner wall of the connecting frame 403. One end of the bolt rod b404 is rotatably connected to the semi-circular block b406. First, place two steel bars on the two moving frames 408 respectively. At this time, rotate the bolt rod b404. When the bolt rod b404 rotates, it drives the semi-circular block b406 to move towards the semi-circular block a407. When the semi-circular block b406 moves a certain distance, the two semi-circular blocks limit the steel bar on the moving frame 408. At this time, the two rotating arc blocks 414 will also clamp the steel bar. Then, turn on the motor 401. The motor 401 drives the bolt rod a409 to rotate, so that the semi-circular blocks a407 and a407 on the two moving frames 408 move towards each other. When the two moving frames 408 move a certain distance, the rapid positioning of the two steel bars is achieved. At this time, the operator can cooperate with the welding mechanism 6 to rotate the steel bars, so as to weld a circle at the connection of the two steel bars.

[0034] It should be noted that, as Figure 4 shown, two arc-shaped grooves 413 are respectively formed on the mutually approaching sides of the semi-circular block a407 and the semi-circular block b406. An arc-shaped clamping block 412 is rotatably connected to the inner wall of the arc-shaped groove 413. A rotating arc block 414 is fixedly connected to the surface of the arc-shaped clamping block 412. The semi-circular block a407 and the semi-circular block b406 form a ring, and at the same time, the two rotating arc blocks 414 also jointly form a ring.

[0035] Two circular rods 405 are symmetrically and fixedly connected to the arc surface of the semi-circular block b406. The circular rods 405 are slidably connected to the connecting frame 403.

[0036] The surface of the bolt rod a409 is provided with a double-thread. The bolt rod a409 is located in the moving groove 411. The two moving frames 408 are respectively located at both ends of the bolt rod a409

[0037] Working principle: In the actual use process, the semi-circular block b406 is driven by the bolt rod b404 to clamp the two steel bars on the two moving frames 408 respectively. At this time, the motor 401 is operated to drive the two sliding frames to move towards each other, so as to quickly align the end faces of the two steel bars. Thus, during the welding process, the steel bars are rotated to weld a circle along the connection of the two steel bars.

[0038] Before welding, the operator can rotate the handle 52. The rotation of the handle 52 will drive the threaded rod 53 on the rotating block 51 to rotate, so as to drive the limiting plate 54 to move in the vertical direction. When the limiting plate 54 moves to a suitable position, the limiting plate 54 will limit the whole device to prevent the device from moving automatically due to vibration.

[0039] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
