Description

Technical Field

[0001] The utility model relates to a component of an automatic gun cleaning machine, in particular to a gun cleaning 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 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 an automatic gun cleaning machine to clean a welding gun, the welding gun must first be clamped and the wire cut. After the wire cutting is completed, the gun must be cleaned by rotating the reamer. The wire cutting and reamer gun cleaning of a traditional gun cleaning machine are independent of each other and not linked. The reamer gun is cleaned by moving the welding gun. However, this method is not convenient for the subsequent oil spraying process, and it is not possible to complete wire cutting, reamer gun cleaning and oil spraying through a one-time clamping. Utility Model Content

[0004] Therefore, in order to solve the above-mentioned shortcomings, the utility model provides a gun cleaning mechanism suitable for an automatic gun cleaning machine, which adapts to the welding gun through the movement of the reamer, overcoming the situation in the traditional structure that the welding gun moves to adapt to the reamer gun cleaning. Through the improvement of the gun cleaning mechanism, the automatic gun cleaning machine can better realize one-time clamping and complete multiple processes (such as wire cutting, gun cleaning, oil spraying, etc.).

[0005] Specifically, a gun cleaning mechanism is installed below the wire cutting mechanism of the gun cleaning machine, and the gun cleaning mechanism includes a vertical driving member, a rotating driving member and a reamer.

[0006] The vertical driving member is fixedly installed vertically and has a telescopic portion that telescopes and moves in the direction of the wire cutting area;

[0007] The rotary drive member is installed in a vertical sliding manner and is connected to the telescopic portion of the vertical drive member. The rotary drive member has a rotating portion, and the reamer is fixedly installed on the rotating portion.

[0008] Optionally, the rotary drive member is equipped with a sliding assembly, the sliding assembly comprising a sliding block and a sliding rail, and the sliding block and the sliding rail are slidably connected;

[0009] The rotating driving member is fixedly connected to the slider;

[0010] The slide rail is vertically fixedly mounted on the frame of the gun cleaning machine.

[0011] Optionally, a protective shell fixed to the frame is provided on the periphery of the slider, the protective shell having a slide rail protection portion matching the slide rail and a covering portion matching the slider, the slide rail protection portion is an elastomer with telescopic properties, and the upper end of the slide rail protection portion is connected to the frame via a protection portion connecting plate.

[0012] Optionally, the reamer is mounted on the rotating part via a reamer seat, and the reamer seat is fixedly mounted on the rotating part via a radially mounted fixing member.

[0013] Optionally, the reamer has a threaded connection portion, the reamer seat has a thread groove, and the threaded connection portion is installed in the thread groove.

[0014] Optionally, a bracket group for mounting the rotating drive member is provided on the cover portion, and the bracket group includes an upper mounting plate and a lower bracket.

[0015] The upper mounting plate and the lower bracket are fixedly mounted on the covering portion.

[0016] The lower bracket includes a semi-circular fixed portion and a semi-circular movable buckle portion, the fixed portion and the movable buckle portion constitute a circular installation area, and the movable buckle portion is connected to the fixed portion by a fastener (such as a screw).

[0017] Optionally, a support rod is fixedly installed between the upper mounting plate and the movable buckle portion (the support rod is fixedly connected to the mounting plate and the movable buckle plate via a nut).

[0018] The utility model has the following advantages:

[0019] The utility model discloses a gun cleaning mechanism of an automatic gun cleaning machine, which cleans the welding gun by rotating the reamer, and rationally designs the vertical driving part, so that the mobile reamer can match the fixed welding gun; compared with the traditional method (the reamer only rotates without other position changes, and the reamer is adapted by moving the welding gun), the continuous control of the gun cleaning machine is more convenient (for example, multiple processes can be completed after clamping the welding gun once).

[0020] By rationally designing the protective shell, dust, debris or oil in the subsequent oil injection process can be reduced from entering between the slide block and the slide rail to affect the sliding of the slide block, thereby improving the spray stability of the reamer moving in the vertical direction.

[0021] By rationally designing the bracket group, the stable installation of the rotating drive member can be achieved, thereby improving the structural stability of the entire gun cleaning mechanism. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] 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.

[0032] 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.

[0033] As described in the background technology, when using an automatic gun cleaning machine to clean a welding gun, it is first necessary to clamp the welding gun and cut the wire, and then complete the gun cleaning by rotating the reamer after completing the wire cutting; while the wire cutting and reamer gun cleaning of the traditional gun cleaning machine are independent of each other and not linked, and the reamer gun cleaning is completed by moving the welding gun, but this method is not convenient for the subsequent oil spraying process, and it is not possible to complete the wire cutting, reamer gun cleaning and oil spraying through a one-time clamping.

[0034] Based on the above reasons, this embodiment provides a gun cleaning mechanism, such as Figure 1 The gun cleaning mechanism is suitable for an automatic gun cleaning machine, which is provided with a clamping mechanism 200, a wire cutting mechanism 300, an oil spraying mechanism 400 and a gun cleaning mechanism 500 installed on a frame 100 in sequence from the welding gun feeding direction. Figure 2 and Figure 3 As shown, the gun cleaning mechanism 500 includes a vertical driving member 501 (such as a linear telescopic cylinder), a rotating driving member 502 (such as a permanent magnet ultra-low energy consumption motor) and a reamer 503.

[0035] The vertical driving member 501 is fixedly mounted on the frame 100 of the gun cleaning machine, and has a telescopic part (such as a telescopic rod of a linear telescopic cylinder) that telescopes and moves in the direction of the wire cutting area. The rotating driving member 502 is slidably mounted on the frame 100 and is connected to the telescopic part of the vertical driving member 501. The rotating driving member has a rotating part (such as a rotating shaft or rotor of a permanent magnet motor), and the reamer is fixedly mounted on the rotating part.

[0036] When the above technical features are used, the vertical driving member drives the rotating member and the reamer to move in the vertical direction, so as to adapt the fixed welding gun by the movement of the reamer, and the rotating driving member drives the reamer to rotate, and the rotating reamer is used to clean the welding gun, thereby completing the cleaning process of the welding gun. Compared with the traditional method (the reamer only rotates, there is no change in other positions, and the reamer is adapted by moving the welding gun), it is more convenient for the continuous control of the automatic gun cleaning machine (for example, multiple processes can be completed after clamping the welding gun once).

[0037] In order to ensure smooth vertical movement of the rotating drive, Figure 1-Figure 2 As shown, in one embodiment, the rotary drive member is equipped with a sliding assembly, such as Figure 2 As shown, the sliding assembly includes a slider 505 and a slide rail 504, wherein the slider 505 and the slide rail 504 are slidably connected; the rotating drive member is fixedly connected to the slider 505; and the slide rail 504 is vertically fixedly installed on the frame of the gun cleaning machine.

[0038] The above technical features enable the rotating drive member to move vertically stably and reliably through the cooperation between the slider and the slide rail, thereby ensuring the accuracy of the movement.

[0039] When cleaning or blowing the welding gun or spraying oil, dust or other foreign matter is likely to enter the contact surface between the slider and the slide rail, thereby affecting the longitudinal movement of the rotating drive member; therefore, in order to overcome this problem, such as Figure 2 and Figure 3 As shown, in order to reduce the impact of dust or foreign matter entering between the slide rail and the slider on sliding, a protective shell is provided on the periphery of the slider, and the protective shell has a slide rail protective part 507 matching the slide rail and a covering part 506 matching the slider. The slide rail protective part is an elastic body with telescopic performance, and the upper end of the slide rail protective part is connected to the rack 100 through a protective part connecting plate 508. The protective shell protects the end of the slider, reduces the risk of foreign matter or dust entering the sliding surface of the slider from the side of the slider, and can also reduce the risk of foreign matter or dust entering the working surface of the slide rail.

[0040] In order to realize the detachable installation of the reamer, Figure 4-Figure 6 As shown, in one embodiment, the reamer 503 is installed on the rotating part 5021 (rotating shaft of the rotating motor) through a reamer seat 5031, and the reamer seat 5031 is fixedly installed on the rotating part 5021 through a radially installed fixing member (such as a fastening screw), and the reamer 503 has a threaded connection part, and the reamer seat has a thread groove, and the threaded connection part is installed on the thread groove; the outer surface of the reamer has a flat part, and the flat part is convenient for the staff to rotate the cylindrical reamer. When in use, the reamer seat is installed on the rotating part through a fastening screw, and transmission can be achieved by installing the fastening screw, and then the reamer is installed on the reamer seat by threaded connection using the thread groove and the threaded connection part. This method can realize the rapid disassembly and assembly of the reamer, and is convenient for replacing the reamer.

[0041] In order to quickly and stably install the rotating drive parts, such as Figure 3 , Figure 7 and Figure 8 As shown, in one embodiment, a bracket group for mounting a rotating driving member is provided on the cover portion 506, and the bracket group includes an upper mounting plate 5062 and a lower bracket 5063.

[0042] The upper mounting plate 5062 and the lower bracket 5063 are fixedly mounted on the covering portion 506.

[0043] The lower bracket 5063 includes a semi-circular fixed portion 5065 and a semi-circular movable buckle portion 5064, wherein the fixed portion and the movable buckle portion constitute a circular mounting area, and the movable buckle portion is connected to the fixed portion by a fastener (such as a screw). A support rod 5061 is fixedly installed between the upper mounting plate and the movable buckle portion (the support rod is fixedly connected to the mounting plate and the movable buckle plate by a nut).

[0044] The above technical features can realize the quick installation of the rotating drive component and improve the installation stability of the rotating component.

[0045] At the same time, the rotating drive member of the utility model is a permanent magnet ultra-low energy consumption motor (the motor has zero gas consumption and consumes 5~10W / min of electricity), which is more energy-saving than the traditional pneumatic motor (gas consumption is 600~800L / min, equivalent to 60~80W / min of electricity consumption); because the traditional pneumatic motor requires the process of electricity→gas→mechanical rotation, and the energy consumption is high; while the permanent magnet ultra-low energy consumption motor does not require too much conversion and has low energy consumption.

[0046] 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.
