Description

Technical Field

[0001] This utility model relates to the field of automated welding technology, and in particular to a welding robot that can automatically clean the welding torch head. Background Technology

[0002] Welding robots are highly automated welding equipment that achieve high-precision and high-efficiency welding tasks through robotic arms and welding equipment. They are mainly used in processes such as welding, cutting, and thermal spraying, and complete the operation by controlling welding parameters (such as current, voltage, and speed) through an automated system.

[0003] During welding, slag, oxides and spatter can easily accumulate inside the welding torch tip. These impurities can interfere with arc stability, leading to weld defects (such as porosity and slag inclusions) and reduced welding strength, thus affecting the quality of the weld.

[0004] When traditional manual cleaning uses brushes and other tools to wipe, the metal welding slag comes into hard contact with the welding nozzle, which can easily leave scratches. Manual cleaning can also easily damage the internal structure of the welding torch nozzle or the contact tip due to improper force, reducing the life of the welding torch, affecting welding performance, and is inefficient with long downtime. It is also easy to miss hidden parts, which affects the working efficiency of the welding robot.

[0005] Therefore, this application provides a welding robot capable of automatically cleaning welding torch heads to meet the demand. Utility Model Content

[0006] The purpose of this invention is to solve the problems existing in the above-mentioned background technology by proposing a welding robot that can automatically clean the welding torch head.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A welding robot capable of automatically cleaning welding torch heads includes: a displacement working module, a frame, an electric welding machine, a high-pressure fan, a robotic arm, a fixed frame, an electric joint, a welding torch, an electric slide, an electric telescopic rod, a fixed base, a sleeve, a nozzle, a nozzle, and an electromagnetic coil. The frame is mounted on the rear side of the displacement working module. The electric welding machine is mounted in the middle of the inner side of the frame. The high-pressure fan is mounted at the lower inner end of the frame. The robotic arm is mounted at the front end of the displacement working module. The fixed frame is mounted at the front end of the robotic arm. An electric joint is mounted at the front end of the fixed frame. The welding torch is mounted on the electric joint. An electric slide is mounted at the bottom of the fixed frame. An electric telescopic rod is mounted at the bottom of the electric slide. A fixed base is mounted on the output shaft of the electric telescopic rod. A sleeve is mounted at the front end of the fixed base. A nozzle is mounted at the upper inner end of the sleeve. An electromagnetic coil is mounted at the lower inner end of the sleeve.

[0009] Preferably, the electric slide is installed horizontally at the bottom of the fixed frame, and the two ends of the electric slide are located at the front and rear ends of the fixed frame, respectively.

[0010] Preferably, the electric telescopic rod is mounted on the slide of the electric slide table, and the electric telescopic rod is movably connected to the fixed frame through the electric slide table.

[0011] Preferably, the electric telescopic rod is vertically installed at the bottom of the electric slide table, and the sleeve at the front end of the fixed seat extends forward to the front end of the electric telescopic rod.

[0012] Preferably, the sleeve is arranged vertically, and both the upper and lower ends of the sleeve are provided with openings.

[0013] Preferably, the nozzle is funnel-shaped and is vertically installed inside the sleeve, with the air pipe of the high-pressure blower passing through the sleeve and connected to the nozzle.

[0014] Preferably, the nozzle is inclined downwards and is connected to the spray pipe.

[0015] Preferably, a plurality of nozzles are provided at the upper inner end of the nozzle, and the plurality of nozzles are arranged in a circular shape at equal intervals around the upper inner end of the nozzle.

[0016] Preferably, the electromagnetic coil is ring-shaped, electrically connected to an external power source via a wire, and located at the lower end of the nozzle outlet.

[0017] Compared with the prior art, this utility model has at least the following beneficial effects:

[0018] In the above solution, compared with traditional welding equipment, the electric slide at the bottom of the fixed frame can drive the electric telescopic rod to move back and forth, thereby approaching and moving away from the welding torch. The electric telescopic rod can drive the fixed seat and sleeve to move up and down, thereby cooperating with the electric slide to move to the bottom of the welding torch, and then rise up to fit into the outer end of the welding nozzle of the welding torch. The high-pressure blower sprays high-pressure gas into the nozzle and sprays it out downward through the nozzle, which can wash away and peel off impurities on the welding nozzle. Several sets of nozzles arranged in a circular and equidistant ring at the upper end of the nozzle surround the outer end of the welding nozzle, which can eliminate cleaning dead corners and thoroughly clean the welding nozzle, making the cleaning more thorough and greatly reducing downtime and maintenance costs.

[0019] In the above solution, an electromagnetic coil is installed at the lower end of the sleeve, and the electromagnetic coil is located at the lower end of the nozzle outlet. When the electromagnetic coil is energized, it generates a magnetic field that can adsorb residual metal welding slag. The welding nozzle can be cleaned without mechanical contact, which can reduce wear on the welding nozzle and extend its service life. The electromagnetic coil uses a magnetic field to adsorb welding slag without mechanical contact, which can reduce wear on the nozzle and extend its service life. Attached Figure Description
