Description

Technical Field

[0001] The utility model relates to an end butt joint positioning structure for steel pipe welding, belonging to the technical field of welding. Background Art

[0002] Welding, also known as fusion welding, is a manufacturing process and technology for joining metals or other thermoplastic materials such as plastics by means of heating, high temperature or high pressure.

[0003] Chinese Patent Publication (Publication No.: CN 205989137 U) discloses a steel pipe welding machine, which includes a base. On the upper surface of the base, two parallel guide rails are respectively arranged. Sliders are respectively nested on the two guide rails. A fixing plate is connected to the top of each slider. A motor is installed on one side of the slider, and the motor can drive the slider to move along the guide rail. Electrode rods are arranged on each fixing plate. Between the two guide rails and along the extending direction of the guide rails, a plurality of cushion blocks are arranged. The orientations of the two electrode rods face the cushion blocks. The steel pipe welding machine of the utility model solves the problems of low manual welding efficiency and high labor intensity in the large-scale production of pipe welding parts when the number of welding points of each steel pipe is relatively large but has a certain linear law. It is simple to operate and reliable in operation;

[0004] However, there are still some defects in the above patent during actual use. The obvious one is that the above patent places the steel pipe on the cushion block, manually aligns the welding end of the steel pipe, and welds the butt joint of the steel pipe through the electrode rod. However, the above equipment may not be able to fixedly clamp the two butt-jointed steel pipes, and cannot automatically butt-joint the steel pipes and then weld them, increasing the labor amount of the operator, reducing the steel pipe welding efficiency, and the welding position is relatively fixed, and the welding operation cannot be adjusted in multiple directions, which may cause welds between the two sections of steel pipes and affect the later use.

[0005] Therefore, an end butt joint positioning structure for steel pipe welding is proposed. Content of the Utility Model

[0006] In view of this, the utility model provides an end butt joint positioning structure for steel pipe welding to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial option.

[0007] The technical solution of the utility model is realized as follows: An end butt joint positioning structure for steel pipe welding includes a bottom plate. A mounting plate is fixedly connected to the rear side of the top of the bottom plate. A fixing mechanism is arranged on the top of the bottom plate. The fixing mechanism includes a notch;

[0008] The notches are formed on the left and right sides of the top of the bottom plate. The middle end of the bottom of the bottom plate is fixedly connected with a mounting seat.

The surface of the first threaded rod is threadedly connected with a first threaded sleeve. The top of the first threaded sleeve is fixedly connected with a support rod. The support rod penetrates through the inner cavity of the notch. The top of the support rod is fixedly connected with a support plate.

[0009] Further preferably, electric push rods are arranged on both the front and rear sides of the support plate. The output ends of the electric push rods are fixedly connected with clamping rings. A plurality of rollers are arranged on the inner walls of the clamping rings.

[0010] Further preferably, an adjusting mechanism is arranged on the top of the mounting plate. The adjusting mechanism includes a multi-output-force air cylinder and a second threaded sleeve. The multi-output-force air cylinder is fixedly connected to the rear side of the top of the mounting plate. A connecting frame is arranged at the output end of the multi-output-force air cylinder. The bottom of the connecting frame is fixedly connected with an adjusting frame.

[0011] Further preferably, a DC motor is fixedly installed on the right side of the adjusting frame. The output end of the DC motor is fixedly connected with a second threaded rod. The outer surface of the second threaded rod is threadedly connected with a second threaded sleeve.

[0012] Further preferably, the bottom of the second threaded sleeve is fixedly connected with a connecting plate. The top of the connecting plate is fixedly connected with an electric cylinder. A welding head is arranged at the bottom of the electric cylinder.

[0013] Further preferably, the top of the second threaded sleeve is fixedly connected with a slider. A chute is formed in the top of the inner cavity of the adjusting frame. The top of the slider is slidably connected in the inner cavity of the chute.

[0014] Further preferably, support cylinders are fixedly connected to the four corners of the bottom of the bottom plate. Fasteners are inserted at the lower ends of the outer sides of the support cylinders. Extension support legs are inserted into the inner cavities of the support cylinders.

[0016] First, by setting the fixing mechanism in the present invention, the electric push rod drives the clamping ring to clamp and fix the steel pipe. The output end of the dual-axis motor drives the first threaded rod to rotate. The first threaded rod drives the first threaded sleeve to move inward through the threaded connection, and then drives the clamping ring to move inward, so that the two ends of the clamped steel pipes are butted and contacted, reducing the labor intensity of the operator and improving the welding efficiency of the steel pipe.
