Description

Technical Field

[0001] This utility model relates to the field of submerged arc welding machine technology, and more specifically, to a high-efficiency submerged arc welding machine for weld seam tracking. Background Technology

[0002] Besides connecting to the power supply, the contact tip of a submerged arc welding machine also guides the welding wire, precisely and stably guiding it into the molten pool. This is especially important for submerged arc welding machines with high penetration depths. The inner diameter of the contact tip cannot be too large; otherwise, the welding wire will wobble during entry into the molten pool, causing it to deviate from the center and resulting in a low weld pass rate. Therefore, the inner diameter of the contact tip needs to be compatible with the welding wire. However, different steel grades and different penetration depths require different types and diameters of welding wire, and existing submerged arc welding machine contact tips cannot accommodate welding wires of varying diameters.

[0003] To address the aforementioned issues, patent document publication number CN210231878U describes a high-penetration deep submerged arc welding machine, comprising a frame, a flux funnel, a wire spool, a wire feeding mechanism, and a conductive nozzle. The lower end of the conductive nozzle is equipped with a wire guiding assembly. This assembly includes a housing fixed to the lower end of the conductive nozzle, a first guide member and a second guide member positioned opposite each other within the housing, and a driving mechanism for moving the first and second guide members in opposite directions. The lower parts of the first and second guide members extend beyond the housing. Both the first and second guide members have vertically arranged arc-shaped guide grooves on their opposite inner sides at one end of the housing, forming a channel between the two arc-shaped guide grooves for the welding wire to pass through.

[0004] However, it still has some drawbacks in actual use. For example, the submerged arc welding machine requires the operator to keep it aligned with the weld seam and move it at a constant speed. It needs to be kept moving during use, which makes it inconvenient to use.

[0005] Therefore, a high-efficiency submerged arc welding machine with weld seam tracking was proposed to solve the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a high-efficiency submerged arc welding machine for weld seam tracking, so as to solve the problem that the existing submerged arc welding machine requires the operator to align it with the weld seam at all times and move it at a constant speed, which is inconvenient during use.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a high-efficiency submerged arc welding machine for weld seam tracking, comprising...

[0008] Base;

[0009] Electric wheels, which are mounted on both sides of the base;

[0010] A bracket, the bottom end of which is fixedly connected to the top of the base;

[0011] A storage box, which is fixedly installed at one end of the top of the bracket;

[0012] A welding assembly, which is disposed at the other end of the top of the bracket;

[0013] A laser sensor is disposed at the bottom of the welding assembly;

[0014] A terminal processor is fixedly mounted in front of a bracket, and is electrically connected to a laser sensor and an electric wheel.

[0015] The welding assembly includes an electric telescopic rod, a connecting plate, a welding head, and a connecting pipe. The top of the connecting plate is fixedly connected to the bottom of the electric telescopic rod, the bottom of the connecting plate is fixedly connected to the top of the laser sensor, the welding head is fixedly mounted on the connecting plate, one end of the connecting pipe is fixedly connected to the top of the welding head, and the other end of the connecting pipe is fixedly connected to the bottom of the storage box.

[0016] It also includes an adjustment component, which is installed on the top of the bracket away from the storage box and is electrically connected to the terminal processor.

[0017] The adjustment assembly includes a fixed plate, a movable block, a support plate, a motor, a gear, and a rack. One end of the fixed plate is fixedly connected to the top of the bracket away from the storage box. The movable block is slidably connected to one side of the fixed plate. The support plate is fixedly installed at the bottom of the movable block. The motor is fixedly installed at the bottom of the support plate and is electrically connected to the terminal processor. The center of the bottom of the gear is fixedly connected to the output end of the motor. The rack is installed on the side of the fixed plate away from the movable block and meshes with the gear.

[0018] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0019] The above solution includes a base, electric wheels, a bracket, a storage box, welding components, a laser sensor, and a terminal processor. Activating the electric telescopic rod lowers the welding head to a suitable height, allowing welding to be performed. Simultaneously, the laser sensor is activated, capturing the weld seam position in real time and sending a signal to the terminal processor. The terminal processor controls the electric wheels to move along the weld seam, enabling the welding head to automatically weld along the seam. This structure allows for automatic tracking of the weld seam, achieving the effects of saving manpower and improving welding efficiency.

[0020] An adjustment component is provided, and the terminal processor can control the motor to start. The motor drives the gear to rotate, and the gear, through meshing with the rack, drives the support plate and the movable block to move. This causes the movable block to slide on one side of the fixed plate, ultimately driving the adjustment component and the laser sensor to move laterally. Through the above structure, the welding component and the laser sensor can be adjusted laterally to achieve the effect of welding various shapes of welds. Attached Figure Description
