Technical Field

[0001] The utility model relates to a bolt cleaning assembly, in particular to a bolt cleaning clamping mechanism. 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 the long-term unobstructed flow of gas, effectively blocking the 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 the welding gun, the welding gun needs to be clamped to facilitate subsequent wire cutting, cleaning and oil spraying, etc., and the traditional gun cleaner positioning mechanism is single-sided clamping or arc clamping, and such clamping method is not convenient for the integration of the gun cleaner (for example, wire cutting, gun cleaning and oil spraying are integrated in this order after clamping), and it is easy to drive the welding gun to move during clamping, which is not convenient for the early positioning of the welding gun. Utility Model Content

[0004] Therefore, in order to solve the above-mentioned shortcomings, the utility model provides a clamping mechanism for a gun cleaning machine, which adopts a center clamping method to reduce the impact of the clamping process on the welding gun position, and can facilitate the subsequent wire cutting and oil spraying processes of the gun cleaning machine.

[0006] The rear end of the clamp arm is a clamp arm connecting portion, which is provided with a mounting groove and a mounting hole passing through the mounting groove. A clamping groove adapted to the welding gun is formed on the inner side of the clamp arm, and two opposite clamping grooves form a welding gun clamping area.

[0007] Optionally, a protective sheet is provided on the inner side of the clamping groove.

[0008] Optionally, a dovetail groove is provided on the inner side of the clamping groove, and the protective sheet is provided with a dovetail-shaped convex ridge adapted to the dovetail groove.

[0009] Optionally, a mounting plate is provided at the tail of the clamping drive member, and the mounting plate includes a vertical drive member connecting portion and a horizontal frame connecting portion, mounting through holes are provided on the drive member connecting portion and the frame connecting portion, and a rib plate is installed between the drive member connecting portion and the frame connecting portion.

[0010] Optionally, the clamping drive member is provided with a protective cover mounted on the frame, the protective cover comprising a front cover and a rear cover, the rear cover covers the clamping drive member, and the front cover is located at the front end of the rear cover;

[0011] The front cover is provided with a clamping protection area, and a clamping arm movable groove is provided on the clamping protection area.

[0012] Optionally, the front cover has a front protrusion located above the movable groove of the clamping arm, and the front protrusion has a clamping groove adapted to the two clamping arms.

[0013] The utility model has the following advantages:

[0014] The utility model discloses a clamping mechanism for an automatic gun cleaning machine, which can realize clamping of a welding gun, so as to facilitate other subsequent processes of the gun cleaning machine (such as wire cutting, gun cleaning and welding gun oil spraying). The central symmetry of the welding gun can be realized through two clamping arms which are symmetrically arranged and move synchronously in opposite directions, thereby improving the stability of clamping and reducing the influence of the clamping mechanism on the position of the welding gun due to structural reasons.

DETAILED DESCRIPTION

[0026] 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.

[0027] 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.

[0028] As described in the background technology, when using a gun cleaner to clean the welding gun, the welding gun needs to be clamped to facilitate subsequent wire cutting, cleaning and oil spraying, etc., and the traditional gun cleaner positioning mechanism is single-sided clamping or arc clamping, and such clamping method is not convenient for the integration of the gun cleaner (for example, wire cutting, gun cleaning and oil spraying are integrated in this order after clamping), and it is easy to drive the welding gun to move during clamping, which is not convenient for the early positioning of the welding gun.

[0029] Based on the above reasons, Figure 1-Figure 3 As shown, this embodiment provides a gun cleaning clamping mechanism, including a clamping drive 104 (for example, a parallel opening and closing pneumatic finger clamping cylinder), two symmetrically arranged clamping arms 106 are connected to the front end of the clamping drive, and the two clamping arms are synchronously driven in reverse by the clamping drive to form a centrally clamped welding gun clamping area;

[0030] The rear end of the clamp arm 106 is a clamp arm connecting portion 1061, which is provided with a mounting groove 1062 and a mounting hole passing through the mounting groove. A clamping groove 107 adapted to the welding gun is formed on the inner side of the clamp arm, and two opposite clamping grooves form a welding gun clamping area.

[0031] When the above technical features are in use, after the welding gun 200 is in place, the clamping drive 104 drives the two clamping arms to move toward the welding gun until the welding gun is clamped; after completing the gun cleaning and oil spraying processes, the clamping drive 104 drives the two clamping arms to move in the opposite direction (reset) to release the clamping of the welding gun.

[0032] The above technical features can realize the center clamping of the welding gun. The center symmetry of the welding gun can be achieved through two symmetrically arranged and synchronously moving clamping arms, thereby improving the stability of clamping; reducing the influence of the clamping mechanism on the position of the welding gun due to structural reasons, and through the reasonable design of the clamping arms, the clamping arms can be quickly loaded and unloaded.

[0033] In order to increase the service life of the clamp arm, Figure 4-Figure 6 As shown, a protective sheet 108 is provided on the inner side of the clamping groove, a dovetail groove 1071 is provided on the inner side of the clamping groove 107, and the protective sheet 108 is provided with a dovetail shaped ridge that matches the dovetail groove 1071. The protective sheet can increase the service life of the clamping arm, and replacing the protective sheet is more convenient and cheaper than replacing the clamping arm. At the same time, the coordination of the dovetail groove and the dovetail shaped ridge makes it more convenient to load and unload the protective sheet; at the same time, the upper end of the dovetail groove is open and the lower end is closed (the dovetail groove is not a through groove), so that the protective sheet can be quickly installed from the top and will not fall off from the bottom.

[0034] In one embodiment, if Figure 7 As shown, the tail of the clamping driver is provided with a mounting plate 105, which includes a vertical driver connection portion 1051 and a horizontal rack connection portion 1052. Both the driver connection portion 1051 and the rack connection portion 1052 are provided with mounting through holes, and a rib plate 1053 is installed between the driver connection portion and the rack connection portion. By rationally designing the mounting plate, the clamping driver can be more stably installed on the vertical rack of the gun cleaner, the vertical driver connection portion can be used to connect with the clamping driver, the horizontal rack connection portion can be used to connect with the rack, the rib plate can be used to improve stability and support capacity, and the mounting hole can be used to facilitate disassembly and assembly.

[0035] In the intelligent gun cleaning machine, after the welding gun is clamped, wire cutting and oil spraying will be performed. Especially when spraying oil, there is a risk that oil will enter the driving parts and affect the normal operation of the driving parts. Therefore, if Figure 8 and Fig. 9 As shown, in one embodiment, the clamping drive member is provided with a protective cover mounted on the frame, and the protective cover includes a front cover 101 and a rear cover 103 (as shown in FIG. Figure 2As shown in the figure, the rear cover is covered with the clamping drive, and the front cover is located at the front end of the rear cover; the front cover is provided with a clamping protection area, and a clamping arm movable groove 1011 is provided on the clamping protection area; the front cover has a front protrusion located above the clamping arm movable groove, and the front protrusion has a clamping groove 102 adapted to the two clamping arms. Through the design of the protective cover, oil is prevented from entering the drive or the components matched with the drive as much as possible, thereby improving the protection and stability of the equipment.

[0036] 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.
