Description

Technical Field

[0001] The utility model relates to the technical field of welding machines, in particular to a split welding torch. Background Technique

[0002] A welding machine uses the high-temperature electric arc generated by the instantaneous short circuit of the positive and negative poles to melt the solder on the welding electrode and the material to be welded, so as to combine the contacted objects. Its structure is very simple, just a high-power transformer. Welding machines can generally be divided into two types according to the type of output power supply, one is an AC power supply and the other is a DC power supply.

[0003] When a welding machine is in use, it is necessary to use wires to connect to two terminal posts through wire noses. However, due to problems such as pulling and moving, the contact position between the wire and the wire nose is prone to reciprocating bending, resulting in the fracture of the battery core inside the wire and affecting the normal conduction of the circuit. Based on this, a split welding torch is proposed to reinforce the connection position between the wire and the welding machine to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a split welding torch, which effectively solves the deficiencies of the prior art.

The outer walls of the two clamping blocks are both slidably connected with mounting shells. At the two corners of the inside of the two mounting shells, limiting strips are fixedly connected. Inside the two mounting shells, there are two arc-shaped pressing blocks. On the top surfaces of the two mounting shells, pressing plates are fixedly connected, which press the four arc-shaped pressing blocks. At one end of the two mounting shells, U-shaped grooves are opened. The two U-shaped grooves are both slidably connected with protective tubes. At one end of the two protective tubes, clamping blocks are fixedly connected. The two clamping blocks are respectively located between the two limiting strips and the U-shaped grooves. Inside the two protective tubes, there are wires. At one end of the two wires, connection heads are fixedly connected, which respectively penetrate through the adjacent two arc-shaped pressing blocks, and the two connection heads are respectively threadedly connected with the two terminal posts.

[0006] Preferably, both sides of the two clamping blocks are recessed inward. At one end of the two clamping blocks far away from the U-shaped groove, there are two protruding parts, which are respectively slidably connected with the recessed positions of the two clamping blocks. This scheme facilitates the sliding connection of the four protruding parts with both sides of the two clamping blocks respectively.

[0007] Preferably, according to any of the above solutions, the four arc-shaped pressing blocks are grouped in pairs, and the top surfaces of the two arc-shaped pressing blocks are higher than the top surface of the mounting shell. In this solution, the four arc-shaped pressing blocks are grouped in pairs, and grooves are recessed between adjacent side surfaces, which is convenient for matching with the connection positions of the wire and the connector to press the two. At the same time, the material of the arc-shaped pressing block can be selected as rubber, which is convenient for it to deform and stably contact the connector and the wire.

[0008] Preferably, according to any of the above solutions, the four corners of the two pressing plates are fixedly connected to the mounting shell by screws, and the bottom surfaces of the two pressing plates are attached to the top surfaces of the two arc-shaped pressing blocks. By using this solution, it is convenient to fix the pressing blocks after installation and fixedly connect them to the top surface of the mounting shell by screws, so as to apply pressure to the two protruding arc-shaped pressing blocks and facilitate pressing the connection position of the wire and the connector.

[0009] Preferably, according to any of the above solutions, grooves are provided on the inner walls of the two U-shaped grooves, and two protective springs are clamped and connected inside the two grooves. The two protective springs are sleeved outside the two protective tubes. The grooves in this solution are convenient for providing an installation position for one end of the two protective springs, thereby limiting one end of the protective springs, stably installing the protective springs on the outer wall of the protective tubes, and protecting the protective tubes.

[0010] Preferably, according to any of the above solutions, one ends of the two connectors are electrically connected to the ends of the two wires by crimping, and external threads are provided at the other ends of the two connectors.
