Description

Technical Field

[0001] The utility model relates to a bolt cleaning machine component, in particular to a wire cutting structure of a bolt cleaning machine. Background Art

[0002] As an auxiliary equipment for welding robots, the intelligent gun cleaner plays an important role in robot automated welding. It is mainly used to clean the flying objects stuck in the gas shield of the welding gun during the automatic welding process of the robot, ensuring long-term unobstructed gas flow, effectively blocking air from entering the welding area, protecting the welding pool and improving the quality of the weld. It can effectively clean the dust accumulated by welding smoke on the conductive nozzle, dredge and clean the protective gas outlet holes on the connecting pipe, spray the protective cover with high temperature resistant anti-blocking agent, reduce the dead adhesion of welding slag to the gun cover and gun nozzle, and increase durability.

[0003] When using a gun cleaner to clean a welding gun, the welding gun needs to be clamped and the welding wire of the welding gun needs to be cleaned for subsequent cleaning and oiling. The wire cutting mechanism of the traditional gun cleaner is a single-sided shear, which is not thorough enough. At the same time, if the welding wire model of the welding gun changes (change in diameter), it is easy for the welding wire to be brought to one side during shearing (because in the single-sided shear structure, one side of the shearing piece is generally fixed and the other side is movable. When the welding wire becomes thinner, it is easy to deviate, especially to the side of the fixed shearing piece, such as Fig.10 As shown in the figure), the deviation process may easily lead to incomplete cutting of the welding wire or cause an external force to the welding gun to deviate to one side, resulting in the risk of the welding gun position deviation. If the welding gun position deviates, it may easily lead to the failure of subsequent cleaning and oil injection. Utility Model Content

[0004] Therefore, in order to solve the above-mentioned shortcomings, the utility model provides a wire cutting structure suitable for an automatic gun cleaning machine. The wire cutting mechanism adopts a symmetrical center shear. The symmetrical center shear can realize that the shearing center point is located on the axis of the welding wire, and no matter how the thickness of the welding wire changes, the shearing center point is located on the axis of the welding wire or the feed direction of the welding gun, thereby ensuring that the welding wire is cut thoroughly and avoiding the risk of position displacement of the welding gun during wire cutting.

[0005] Specifically, a wire cutting structure of a gun cleaning machine, the gun cleaning machine includes a clamping mechanism and an oil injection mechanism, the wire cutting mechanism is installed between the clamping mechanism and the oil injection mechanism, the wire cutting mechanism includes a wire cutting drive, two shearing pieces are connected to the front end of the wire cutting drive, and the two shearing pieces are synchronously and reversely driven by the wire cutting drive.

[0006] The shearing piece comprises a cutter and a cutter seat. The cutters in the two shearing pieces have different heights and are installed in a staggered manner.

[0007] Optionally, the cutter seat includes a seat plate, a sunken cutter mounting portion is provided on the inner side of the front end of the seat plate, and a vertical connecting portion connected to the wire cutting drive member is provided at the rear end of the seat plate, the vertical connecting portion has a mounting hole and a positioning protrusion.

[0008] Optionally, the wire cutting drive comprises a housing, in which a cylinder unit, an oblique push block and two oblique sliding blocks are arranged, and the oblique push block is connected to the telescopic rod of the cylinder unit;

[0009] The two inclined sliding blocks are respectively installed on both sides of the inclined push block by means of sliding groove connection;

[0010] The vertical connection portion is connected to the inclined sliding block.

[0011] Optionally, a support rib is installed between the vertical connecting portion and the seat plate.

[0012] Optionally, the wire cutting structure of the gun cleaning machine further includes a protective cover, which includes a wire cutting protection area, and two strip grooves adapted to the shearing piece are provided in the wire cutting protection area.

[0013] The utility model has the following advantages:

[0014] The utility model designs a wire shearing driving member, and two shearing pieces that move synchronously and in opposite directions are connected to the front end of the wire shearing driving member, so as to realize symmetrical center shearing. The symmetrical center shearing can realize that the shearing center point is located on the axis of the welding wire, and no matter how the diameter of the welding wire changes, the shearing center point is located on the axis of the welding wire or the feeding direction of the welding gun (such as Fig.11 As shown, the shear center point is located on the axis of the welding wire, and the welding gun is moving in the vertical downward direction as shown in the figure), which ensures that the welding wire is sheared thoroughly and avoids the risk of position displacement of the welding gun when shearing the wire.

DETAILED DESCRIPTION

[0027] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0028] In this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises", or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article, or apparatus.

[0029] As described in the background technology, when using a gun cleaner to clean a welding gun, the welding gun needs to be clamped and the welding wire of the welding gun needs to be cleaned for subsequent cleaning and oiling, etc., while the wire cutting mechanism of the conventional gun cleaner is a single-sided shear, which is not thorough enough. At the same time, if the welding wire model of the welding gun is changed (change in diameter), it is easy for the welding wire to be brought to one side during shearing (because in the single-sided shear structure, one side of the shearing piece is generally fixed and the other side is movable. When the welding wire becomes thinner, it is easy to deviate, especially to the side of the fixed shearing piece, such as Fig.10As shown in the figure), the deviation process may easily lead to incomplete cutting of the welding wire or cause an external force to the welding gun to deviate to one side, resulting in the risk of the welding gun position deviation. If the welding gun position deviates, it may easily lead to the failure of subsequent cleaning and oil injection.

[0030] Based on the above reasons, Figure 1-Figure 3 As shown, the utility model provides a wire cutting structure 300 of a gun cleaning machine, the gun cleaning machine includes a clamping mechanism 400 and an oil injection mechanism 100, the wire cutting mechanism is installed between the clamping mechanism and the oil injection mechanism, the wire cutting mechanism 300 includes a wire cutting drive member 301, and two shearing pieces 302 are connected to the front end of the wire cutting drive member 301, and the two shearing pieces 302 are synchronously and reversely driven by the wire cutting drive member 301.

[0031] When the above features are implemented, after the clamping mechanism completes clamping the welding gun, the wire cutting drive drives the two shearing pieces to move, and the wire cutting drive drives synchronously and reversely, and when the wire cutting pieces are close to the wire cutting pieces, the wire cutting can be completed. The above technical features can realize symmetrical center shearing, and the symmetrical center shearing can realize that the shearing center point is located on the axis of the welding wire, and no matter how the diameter of the welding wire changes, the shearing center point is located on the axis of the welding wire (such as Fig.11 As shown in the figure, the shear center point is located on the axis of the welding wire), which ensures that the welding wire is sheared thoroughly and avoids the risk of position deviation of the welding gun when shearing the wire.

[0032] During the wire cutting process, the sharpness of the shearing blade can affect the wire cutting efficiency, so the shearing blade needs to be replaced regularly. Therefore, in order to facilitate the loading and unloading of the shearing blade and improve the wire cutting efficiency; Figure 3-Figure 6 As shown, the shearing piece 302 includes a cutter 304 and a cutter seat 303. The cutters 304 in the two shearing pieces 302 are of different heights and are installed in a staggered manner. The cutter seat 303 includes a seat plate, a sunken cutter installation portion 3032 is provided on the inner side of the front end of the seat plate, and a vertical connection portion connected to the wire cutting drive member is provided at the rear of the seat plate. The vertical connection portion has a mounting hole and a positioning protrusion 3031, and a support rib is installed between the vertical connection portion and the seat plate.

[0033] In the above technical features, the two cutters are of different heights and are installed in a staggered manner to ensure the shearing quality and reduce the possibility of the welding wire not breaking during shearing; the sunken cutter installation part can be used to position the cutter and improve the efficiency of cutter installation; the reasonably designed positioning protrusion can achieve rapid positioning, and the support ribs can improve the strength of the seat plate.

[0034] In order to realize that the wire cutting drive member drives the two shearing pieces to move synchronously and in opposite directions, in one embodiment, the wire cutting drive member includes a housing, in which a cylinder unit 3013, an oblique push block 3012 and two oblique slide blocks 3011 are arranged. Figure 7As shown, the oblique push block 3012 is connected to the telescopic rod of the cylinder unit; the two oblique sliding blocks are respectively installed on both sides of the oblique push block by means of sliding groove connection; and the vertical connection part is connected to the oblique sliding block.

[0035] The above technical features enable one movement of a cylinder unit to drive two shearing pieces to move synchronously and in opposite directions, thereby achieving symmetrical center shearing of the welding wire.

[0036] In the intelligent gun cleaning machine, the welding gun will spray oil after completing wire cutting. When spraying oil, there is a risk that oil will enter the wire cutting drive and affect the normal operation of the drive. Therefore, Figure 8 and Fig. 9 As shown, in one embodiment, the wire cutting structure of the gun cleaning machine further includes a protective cover 200, which includes a wire cutting protection area, and two strip grooves 201 adapted to the shearing piece are opened in the wire cutting protection area.

[0037] Through the design of the above-mentioned protective cover, oil is avoided as much as possible from entering the wire cutting drive or components matching the drive, thereby improving the protection and stability of the equipment; and the two strip grooves can facilitate the lateral movement of the shearing piece, and the two strip grooves are closed and maintained at a distance, which can also limit the shearing piece.

[0038] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
