Description

Technical Field

[0001] This utility model relates to the field of welding equipment, and in particular to a portable assembly structure for an arc voltage sensing wire feeder based on a toolbox. Background Technology

[0002] A wire feeder is a welding auxiliary device controlled by a microcomputer. It is mainly used for continuous and stable feeding of welding wire in scenarios such as argon arc welding, laser welding, and plasma welding. Its core function is to replace manual operation to improve welding efficiency and accuracy.

[0003] For example, Chinese patent CN210060071U discloses a wire feeder that winds welding wire around a rotating shaft. When the wire clamping and feeding part is powered on, it clamps and feeds the welding wire. The wire clamping and feeding part can drive the rotating shaft to rotate, and the two wire spools rotate under the drive of the rotating shaft. Since the roller is in contact with the wire spool, the wire spool can drive the roller to rotate, and the roller can provide an upward supporting force to the wire spool. This can solve the problem in the prior art where the central axis of the wire spool deforms after long-term use, causing the wire spool to be obstructed from rotating, resulting in uneven wire feeding and welding quality accidents.

[0004] However, traditional wire feeders can only be equipped with constant voltage power supplies and are not convenient to carry, thus limiting their practical application. Utility Model Content

[0005] The core of this utility model lies in integrating all components into a toolbox, which can be matched with a constant voltage or constant current power supply, and can be input using a long cable to realize remote current adjustment, solving the problem that the wire feeder in the prior art can only be matched with a constant voltage power supply; at the same time, it achieves effective dust and water protection, and is easy to carry and transport.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A portable assembly structure for an arc voltage sensing wire feeder based on a toolbox includes a toolbox, with a toolbox handle fixedly connected to the outer end of the toolbox. Inside the toolbox, a frame structure and a motor bracket are connected by screws. A motor assembly is fixedly connected to the upper end of the motor bracket. The surface of the frame structure is provided with multiple grooves and bosses. A switching power supply board, a control board, and a contactor are fixedly connected to the multiple grooves. A temperature controller is fixedly connected to the upper end of the contactor. A wire spool is fixedly connected to the boss.

[0008] The front panel is fixedly connected to the front end of the toolbox. A European-style central socket is provided on the side of the front panel away from the toolbox. The European-style central socket is connected to the front panel through a flange. The contactor is electrically connected to the European-style central socket through a copper strip. A display panel, a switch and a grounding socket are also fixedly connected to the front panel. A knob is also connected to the display panel.

[0009] Furthermore, a base is fixedly connected to the bottom of the toolbox.

[0010] Furthermore, a rear cover plate is bolted to the rear end of the toolbox, and a solenoid valve is fixedly connected to the outer end of the rear cover plate.

[0011] Furthermore, a knob protection plate is provided on the outside of the knob and is fixedly connected to the front panel.

[0012] Furthermore, a functional cover plate is fixedly connected to the surface of the frame structure, and the functional cover plate is located on the side of the control panel away from the frame structure.

[0013] Compared with existing technologies, the advantages of this utility model are:

[0014] This solution integrates the wire spool, switching power supply board, control board, motor assembly, contactor, temperature controller, and other structures into a toolbox, forming a modular arc voltage wire feeder. It can be matched with a constant voltage or constant current power supply and can use a long cable input to achieve remote current adjustment, solving the problem that existing wire feeders can only be matched with constant voltage power supplies. At the same time, it achieves effective dust and water protection and is easy to carry and transport. Attached Figure Description

Detailed Implementation

[0026] The technical solution will now be clearly and completely described with reference to the accompanying drawings in the embodiments of this utility model.

[0027] First implementation method:

[0028] Please see Figures 1-9 A portable assembly structure for an arc voltage sensing wire feeder based on a toolbox includes a toolbox 101. A toolbox handle 102 is fixedly connected to the outer end of the toolbox 101. Inside the toolbox 101, a frame structure 201 and a motor bracket 203 are connected by different screws. The frame structure 201 is made of sheet metal, with multiple folds to increase strength and precise positioning welding to ensure dimensional accuracy. A motor assembly 303 is fixedly connected to the upper end of the motor bracket 203, and the motor assembly 303 is isolated from the motor bracket 203 by an insulating washer to ensure the working strength and insulation of the motor assembly 303.

[0029] Please see Figure 2 and Figure 3 The frame structure 201 has multiple grooved surfaces and protruding surfaces 204. A switching power supply board 301, a control board 302, and a contactor 304 are fixedly connected to the grooved surfaces. A temperature controller 305 is fixedly connected to the upper end of the contactor 304. A screw spool 103 is fixedly connected to the protruding surface 204. The screw spool 103 is located at the center of the toolbox. When it is under force, it can effectively reduce the probability of the toolbox 101 tipping over. The protruding surface 204 is located outside the groove of the grooved surface, so that the protruding surface 204 can effectively protect the switching power supply board 301 and the contactor 304 from being squeezed and deformed. At the same time, a functional cover plate 202 is also fixedly connected to the surface of the frame structure 201. The functional cover plate 202 is located on the side of the control board 302 away from the frame structure 201. The functional cover plate 202 is used to protect the control board 302 from being squeezed and deformed.

[0030] Please see Figure 3 and Figure 4A front panel 207 is fixedly connected to the front end of the toolbox 101. A European-style central socket 307 is provided on the side of the front panel 207 away from the toolbox 101. The European-style central socket 307 is connected to the front panel 207 via a flange 312. A contactor 304 is electrically connected to the European-style central socket 307 via a copper strip. A display panel 308, a switch 310, and a grounding socket 311 are also fixedly connected to the front panel 207. The display panel 308 is located between the front panel 207 and the toolbox 101, and multiple openings are provided on the front panel 207. The display panel 308 has a through hole for partial exposure. A knob 309 is also connected to the display panel 308. The knob 309 is located on the side of the front panel 207 away from the toolbox 101. The display panel 308 passes through one of the through holes and is connected to the knob 309. A knob protection plate 208 is provided on the outside of the knob 309 and is fixedly connected to the front panel 207. The knob protection plate 208 can effectively protect the knob 309 and prevent it from being easily bumped. At the same time, the size of the knob protection plate 208 is smaller than that of the knob 309, making it convenient for personnel to manually operate the knob 309.

[0031] The bottom of the toolbox 101 is fixedly connected to a base 205, which is used to make the toolbox 101 stable when standing upright and to make it easy for its lid to be opened horizontally.

[0032] The rear end face of the toolbox 101 is bolted to a rear cover plate 206, and a solenoid valve 306 is fixedly connected to the outer end of the rear cover plate 206.

[0033] By integrating the wire spool 103, switching power supply board 301, control board 302, motor assembly 303, contactor 304, temperature controller 305, and other structures onto a toolbox, a modular arc voltage wire feeder is formed. This feeder can be matched with a constant voltage or constant current power supply and can use a long cable for input, enabling remote current adjustment. This solves the problem that existing wire feeders can only be equipped with constant voltage power supplies. It also achieves effective dust and water protection and is easy to carry and transport. Supplementary explanation: In this application, all electrical components, including the wire spool 103, switching power supply board 301, control board 302, motor assembly 303, contactor 304, temperature controller 305, and solenoid valve 306, are the main components of the wire feeder. Their functions are the same as those of similar components in existing wire feeders; therefore, their circuit connections and principles are not detailed here.
