[0021] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the accompanying drawings of the embodiments of the present utility model will be combined below Figures 1 - 3 , and the technical solutions of the embodiments of the present utility model will be described clearly and completely. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the described embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present utility model.

[0022] As Figures 1 - 3 shown: This embodiment provides a wire feeding wheel adjusting device for a wire feeder. The adjusting device is arranged on the wire feeder and is perpendicular to the conveying direction of the welding wire. It includes a synchronous pitch adjustment assembly 100 arranged on the wire feeder. Two wire feeding wheel bodies 200 are rotatably arranged on the synchronous pitch adjustment assembly 100. The welding wire is located between the two wire feeding wheel bodies 200. The present utility model can conveniently and quickly synchronously adjust the distance between the two wire feeding wheel bodies 200 through the synchronous pitch adjustment assembly 100, without the need for secondary calibration and centering operations, facilitating the stable and efficient conveying operation of welding wires of various specifications and diameters, greatly improving the efficiency of wire feeding wheel pitch adjustment, and improving the wire feeding efficiency of the wire feeder.

[0023] According to an embodiment of the present utility model, as Figures 1 - 3As shown in the figure, the synchronous pitch adjustment component 100 includes a slide rail 101 provided on the wire feeder. Two sliders 102 are slidably arranged inside the slide rail 101. Threaded holes with opposite thread pitches are provided on the two sliders 102 along the length direction of the slide rail 101. A bidirectional bolt 103 is threadedly connected to the threaded holes of the two sliders 102. The nut of the bidirectional bolt 103 is located outside the slide rail 101. In the present utility model, the bidirectional bolt 103 can be rotated. Due to the threaded connection between the bidirectional bolt 103 and the two sliders 102, as well as the guiding and limiting effects of the slide rail 101 on the two sliders 102, the rotating bidirectional bolt 103 can drive the sliders 102 threadedly connected to it to move towards each other along the slide rail 101, thereby realizing the synchronous adjustment operation of the positions of the two sliders 102, and the operation is more convenient and efficient.

[0024] According to another embodiment of the present utility model, as Figure 1 and Figure 2 shown, an adjustment groove 104 is provided on the outer side wall of the slide rail 101 on one side. Locking bolts 105 are respectively threadedly connected to the outer side walls of the two sliders 102. The nuts of the locking bolts 105 are located outside the adjustment groove 104. In the present utility model, the locking bolts 105 can be loosened, and then the bidirectional bolt 103 can be rotated to synchronously adjust the positions between the two sliders 102. Moreover, after the positions of the two sliders 102 are adjusted, the adjusted sliders 102 can be locked by tightening the locking bolts 105, avoiding the change in the distance between the sliders 102 caused by the extension of the service time during the wire feeding process of the wire feeding wheel, which greatly increases the firm stability of the positions of the sliders 102 after adjustment.

[0025] A gasket 106 is sleeved on the outer side of the screw rod of the locking bolt 105 and inside the nut of the locking bolt 105. In the present utility model, the gasket 106 can be used to prevent the lower part of the nut of the locking bolt 105 from directly squeezing against the outer side wall of the slide rail 101 and causing damage.

[0026] According to another embodiment of the present utility model, as Figure 1 and Figure 3 shown, a rotating shaft 300 is provided on the axis of the wire feeding wheel body 200. A bearing is provided at the lower part of the rotating shaft 300. The outer ring of the bearing is fixed to the upper part of the slider 102 located on the same vertical line as it.

[0027] A positioning hole 400 is provided on the axis of the wire feeding wheel body 200. The rotating shaft 300 is inserted into the positioning hole 400 and is in interference fit with the positioning hole 400. The size of the rotating shaft 300 is slightly larger than the size of the positioning hole 400. The range of the interference amount is 0.01 mm to 0.03 mm. The positioning hole 400 on the wire feeding wheel body 200 is press-fitted onto the rotating shaft 300 by means of cold press fitting.

[0028] A protective sleeve is provided on the outer side of the wire feeding wheel body 200. The protective sleeve should be made of anti-slip, wear-resistant and high-temperature-resistant rubber material. The utility model can avoid slipping or crushing caused by direct contact with the wire feeding wheel body 200 during the process of conveying the welding wire through anti-slip, greatly improving the stability of the welding wire conveying.

[0029] The usage method of the utility model:

[0030] First of all, it should be clear that the adjustment device involved in the utility model is mainly used for the adjustment operation of the distance between the wire feeding wheel bodies 200 during the process of the wire feeder conveying the welding wire. The adjustment device is arranged on the wire feeder and is perpendicular to the conveying direction of the welding wire. The utility model takes the adjustment of the distance between the wire feeding wheel bodies 200 as an example to elaborate its usage method in detail. When the distance between the wire feeding wheels needs to be adjusted, first use a wrench to loosen the locking bolt 105 until the gasket 106 is separated from the outer side wall of the slide rail 101, and then use a wrench to turn the bidirectional bolt 103. By turning the bidirectional bolt 103, due to the threaded connection between the bidirectional bolt 103 and the two sliders 102 and the guiding and limiting effects of the slide rail 101 on the two sliders 102, the rotating bidirectional bolt 103 can drive the sliders 102 threaded to it to move towards each other along the slide rail 101, thereby realizing the synchronous adjustment operation of the positions of the two sliders 102. After the adjustment is completed, reverse-turn the locking bolt 105 to lock the sliders 102 with adjusted positions, and then the welding wire conveying operation can be carried out. The utility model can realize the convenient and rapid synchronous adjustment operation of the distance between the two wire feeding wheel bodies 200 through the synchronous distance adjustment component 100, without the need for secondary alignment and centering operations, facilitating the stable and efficient conveying operation of welding wires of various specifications and diameters, solving the problems that the operation of the wire feeding wheels of the traditional wire feeder is cumbersome during the adjustment process, and it is necessary to repeatedly align and correct the symmetric vertical plane between the two adjusted wire feeding wheels and the vertical plane where the axis of the conveying direction of the welding wire is located to make them coincide, the centering operation is cumbersome, the efficiency is low, greatly reducing the efficiency of the wire feeding wheel distance adjustment and the wire feeding efficiency of the wire feeder.

[0031] In addition, it should also be noted that in the description of the present utility model, unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0032] The above are the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
