Description

Technical Field

[0001] The utility model belongs to the technical field of welding gun cleaning, in particular to a light and small-torque wire cutter. Background Art

[0002] Before the welding gun cleaner is used to clean the welding gun, the weld nodules formed on the welding wire head of the welding gun during welding operations need to be sheared to improve the welding quality of the welding gun in subsequent welding operations. The currently used separate wire cutting device requires the welding gun, the gun cleaner, and the separate wire cutting device to be positioned separately, which is cumbersome to use. In addition, after the welding wire of the welding gun is moved to the separate wire cutting device for cutting, it is then moved to the gun cleaner for cleaning, which reduces the work efficiency of the entire welding process. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a light and small torque wire cutter arranged on the side of a gun cleaner to improve the working efficiency of the entire welding operation process.

[0004] In order to solve the above technical problems, the present invention is achieved through the following technical solutions: a lightweight and small-torque wire cutter, comprising a gun cleaner body, a wire cutter base, a telescopic cylinder, a wire cutter blade, a wire cutter block and a material collection channel, the wire cutter base is fixedly mounted on the gun cleaner body, the cylinder body and the material collection channel of the telescopic cylinder are fixedly mounted on the wire cutter base, a gap is provided between the wire cutter block and the wire cutter base, the front end of the wire cutter blade is mounted on the wire cutter base through a rotating shaft, and the wire cutter blade is located in the gap, a long waist hole is provided behind the wire cutter blade, a pin rod is fixedly mounted on the front end of the piston rod of the telescopic cylinder, and the pin rod is slidably mounted in the long waist hole of the wire cutter blade.

[0005] Preferably, the wire cutting base has a through hole, and the piston rod of the telescopic cylinder slides through the through hole.

[0006] Preferably, the top side of the aggregate channel has a shearing notch.

[0007] Preferably, a collecting hopper is fixedly mounted on the gun cleaner body, and the collecting hopper is located at the lower part of the collecting channel.

[0008] Preferably, an inclined material guide plate is provided at the lower portion of the material collecting channel, and an extension line of the inclined material guide plate extends into the material collecting hopper.

[0009] Compared with the prior art, the utility model has the following advantages: the wire cutter is compact and light in structure, can be directly installed on the outside of the gun cleaner body, reduces the problem of long gun cleaning distance caused by cutting the welding wire with the cutter alone, can improve the efficiency of welding gun cleaning, and the work efficiency of the entire welding process. The welding nodules at the head of the welding wire are cut off by the wire cutting blade and the wire cutting block, and the fallen welding nodules are collected and processed through the collection channel.

[0014] The utility model is described in detail below in conjunction with specific implementation methods:

[0015] like Figures 1 to 3 A light and small torque wire cutter is shown, comprising a gun cleaner body 1, a wire cutter base 2, a telescopic cylinder 3, a wire cutter blade 6, a wire cutter block 8 and a material collection channel 9, wherein the wire cutter base 2 is fixedly mounted on the gun cleaner body 1, the cylinder body of the telescopic cylinder 3 and the material collection channel 9 are both fixedly mounted on the wire cutter base 2, a gap is provided between the wire cutter block 8 and the wire cutter base 2, the front end of the wire cutter blade 6 is mounted on the wire cutter base 2 through a rotating shaft, and the wire cutter blade 6 is located in the gap, a long waist hole is provided behind the wire cutter blade 6, a pin is fixedly mounted on the front end of the piston rod of the telescopic cylinder 3, the pin is slidably mounted in the long waist hole of the wire cutter blade 6, and the diameter of the long waist hole is twice the diameter of the pin to avoid the wire cutter blade 6 from getting stuck with the pin on the piston rod during rotation. The wire cutter base 2 has a through hole 21, and the piston rod of the telescopic cylinder 3 slides through the through hole 21.

[0016] The top side of the collecting channel 9 is provided with a shearing notch 91, and the welding wire at the head of the welding gun can be translated into the shearing opening formed by the wire cutting blade 6 and the wire cutting block 8 through the shearing notch 91. It is no longer necessary to move the welding gun upward so that the welding wire at the head is higher than the shearing opening and then move downward, which can improve the feeding efficiency.

[0017] A collecting hopper 5 is also fixedly mounted on the gun cleaner body 1 , and the collecting hopper 5 is located at the lower part of the collecting channel 9 . The weld nodules cut off from the welding wire at the welding gun head enter the collecting channel 9 and then slide into the collecting hopper 5 .

[0018] When the collecting hopper 5 is installed at a position not directly below the collecting channel 9, an inclined guide plate 92 is provided at the lower part of the collecting channel 9, and the extension line of the inclined guide plate 92 extends into the collecting hopper 5. The weld nodules that slip down in the collecting channel 9 fall into the collecting hopper 5 for collection under the guidance of the inclined guide plate 92.

[0019] Before cleaning the welding gun, the welding wire is driven to move into the shearing notch formed by the wire cutting blade 6 and the wire cutting block 8. The telescopic cylinder 3 pushes the wire cutting blade 6 to rotate around the rotating shaft. After the wire cutting blade 6 and the wire cutting block 8 come into contact with each other, the weld nodule at the head of the welding wire is cut off and falls into the aggregate channel 9 for collection and processing.
