Description

Technical Field

[0001] The utility model relates to a welding gun cleaning device, in particular to a semi-automatic gun cleaning machine. Background Art

[0002] Welding guns are a key tool in welding operations, and cleaning them after use is crucial to ensuring the next welding operation goes smoothly and ensuring weld quality. Welding gun cleaning typically involves cutting the wire, cleaning the reamer, and spraying oil. Sometimes, a purge operation is required between reamer cleaning and oiling to ensure the cleanliness and patency of the welding gun interior and nozzle, thereby preventing welding defects and improving welding efficiency and quality.

[0003] Currently, small and medium-sized enterprises generally employ a multi-station cleaning approach for welding torch cleaning, performing processes such as wire cutting, cleaning, and oiling in separate areas. While this decentralized cleaning process covers all necessary steps for welding torch cleaning, it presents significant challenges: the welding torch must be frequently moved between multiple stations, resulting in a wide range of movement and a lack of centralized cleaning, leading to overall low cleaning efficiency. Furthermore, this multi-station cleaning approach can increase the risk of damage to the welding torch during transport, further impacting the stability and reliability of welding operations.

[0004] In order to overcome the shortcomings of the multi-station cleaning method, some intelligent gun cleaning machine products have appeared on the market, such as the intelligent gun cleaning machine with publication number CN 118577912 A applied for by the applicant on July 4, 2024. This type of intelligent gun cleaning machine can integrate all processes such as wire cutting, reamer cleaning, purging and oiling into one, realizing automatic cleaning of the welding gun, greatly improving cleaning efficiency and accuracy. However, although the intelligent gun cleaning machine has significant advantages in performance, its high cost has become a huge obstacle to the promotion and application of small and medium-sized enterprises. For small and medium-sized enterprises with relatively limited financial resources, the introduction of intelligent gun cleaning machines will significantly increase production costs, which is not conducive to the long-term development of the enterprise.

[0005] Therefore, it is necessary to develop a new welding gun cleaning device that can not only meet the welding gun cleaning needs but also reduce the cleaning costs to meet the actual needs of small and medium-sized enterprises. Utility Model Content

DETAILED DESCRIPTION

[0037] Embodiments of the present application are described in detail below with reference to the attached drawing figures, wherein the same or like reference numerals and characters throughout the figures denote the same or like elements or elements having the same or similar functions. The embodiments described below are exemplary and intended to be illustrative of the present application and are not to be understood as limiting of the present application.

[0038] In this document, relational terms such as first and second and the like can be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. The terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus.

[0039] As described in the background, the welding gun as a key tool in the welding operation, its cleaning work after use is an important link to ensure the smooth progress of the next welding operation and to ensure the welding quality. The welding gun cleaning usually includes wire cutting, reamer cleaning and oil injection, sometimes between the reamer cleaning and oil injection, blowing operation is also needed to ensure the cleanliness and smoothness of the welding gun and the nozzle, so as to avoid welding defects, improve the welding efficiency and quality.

[0040] Currently, small and medium-sized enterprises generally employ a multi-station cleaning approach for welding torch cleaning, performing processes such as wire cutting, cleaning, and oiling in separate areas. While this decentralized cleaning process covers all necessary steps for welding torch cleaning, it presents significant challenges: the welding torch must be frequently moved between multiple stations, resulting in a wide range of movement and a lack of centralized cleaning, leading to overall low cleaning efficiency. Furthermore, this multi-station cleaning approach can increase the risk of damage to the welding torch during transport, further impacting the stability and reliability of welding operations.

[0041] In order to overcome the shortcomings of the multi-station cleaning method, some intelligent gun cleaning machine products have appeared on the market, such as the intelligent gun cleaning machine with publication number CN 118577912 A applied for by the applicant on July 4, 2024. This type of intelligent gun cleaning machine can integrate all processes such as wire cutting, reamer cleaning, purging and oiling into one, realizing automatic cleaning of the welding gun, greatly improving cleaning efficiency and accuracy. However, although the intelligent gun cleaning machine has significant advantages in performance, its high cost has become a huge obstacle to the promotion and application of small and medium-sized enterprises. For small and medium-sized enterprises with relatively limited financial resources, the introduction of intelligent gun cleaning machines will significantly increase production costs, which is not conducive to the long-term development of the enterprise.

[0042] Based on the above reasons, this embodiment provides a semi-automatic gun cleaning machine, such as Figures 1-6 As shown, it includes a base body, on which a wire cutting mechanism and a gun cleaning mechanism are installed;

[0043] The wire cutting mechanism includes a fixed shearing knife 401, a movable shearing knife 402, a swing rod 404 and a swinging power piece 405. The fixed shearing knife 401 is fixedly installed on the base, and the swing rod 404 is rotatably installed on the base through a pin 403. One end of the swing rod 404 is connected to the swinging power piece 405, and the other end is connected to the movable shearing knife 402. The movable shearing knife 402 is adapted to the fixed shearing knife 401.

[0044] The gun cleaning mechanism includes a lifting power member 303, a reamer 301, and a rotating power member 302. The rotating power member 302 is connected to the lifting power member 303 via a movable plate 304. The reamer 301 is mounted on the rotating shaft of the rotating power member 302, and the lifting power member 303 is fixedly mounted to the base. Preferably, the swinging power member is a telescopic cylinder, the lifting power member is a vertically mounted telescopic cylinder, and the rotating power member is a pneumatic motor.

[0045] The above technical features can realize the wire cutting and cleaning of the welding gun. Through the swinging wire cutting mechanism, the shearing force is effectively increased, thereby improving the shearing quality. This design makes the wire cutting process more stable and reliable, ensuring that the welding wire can be cut cleanly and neatly, avoiding subsequent problems caused by incomplete shearing; in order to prevent the shear knife from injuring the staff during wire cutting, the wire cutting mechanism is provided with a wire cutting protective cover installed on the box. At the same time, in the above technical features, a lifting gun cleaning mechanism is adopted, and a telescopic cylinder is used as the lifting power part, which can smoothly and reliably lift the reamer to the specified position, making it convenient to clean the welding gun. This design not only improves the cleaning efficiency, but also reduces the difficulty of operation, making the cleaning process easier and more convenient.

[0046] In order to solve the problem of positioning the welding gun when the reamer cleans the welding gun, a clamping mechanism fixed to the base is installed above the gun cleaning mechanism, and the clamping mechanism includes a clamping power member 201, on which two clamping arms 202 are installed. The two clamping arms move toward each other when clamping and move in opposite directions when releasing the clamping; preferably, the clamping power member is a parallel opening and closing pneumatic finger clamping cylinder.

[0049] The above technical features enable oil spraying on the welding gun, and the proper placement of an oil spray cover on the oil spray nozzle effectively reduces the environmental impact of the oil sprayed from the nozzle. Furthermore, the oil spray cover also allows for positioning of the welding gun, ensuring a more accurate and reliable oil spraying process, and improving both efficiency and quality.

[0050] In order to prevent debris from falling when the reamer cleans the welding gun, in one embodiment, a collecting trough 102 is installed on the base below the gun cleaning mechanism. Preferably, the collecting trough is hung on the base, exemplarily, a gourd-shaped hanging hole is formed on the collecting trough, and a hanging nail is installed on the box body.

[0051] The rationally designed aggregate trough in the above technical features can accommodate the debris dropped when the reamer cleans the welding gun, and is installed in a hanging manner, which makes it easy for workers to clean and load and unload the aggregate trough, reducing the difficulty of work.

[0052] In order to improve the compactness of the base, in one embodiment, the base includes a bracket 103 and a box 100 . The box 100 is fixedly installed above the bracket 103 , and the lifting power member 303 is fixedly installed in the box 100 .

[0053] An oil box placement area is provided on the rear side of the box body. The placement area is concave and is provided with an oil box placement plate 505.

[0054] In order to realize the up and down movement of the movable plate, in one embodiment, the box body is provided with a through slot for facilitating the lifting and lowering of the movable plate;

[0055] A guard plate 305 fixed to the movable plate is provided on one side of the through slot;

[0056] A protective cover 101 adapted to the guard plate is provided on the box body.

[0057] In the above technical features, the through grooves prevent the box from interfering with the movement of the movable plate, and the through grooves can also be used to limit the middle stop point of the movable plate; the guard plate and the protective cover can prevent foreign matter from entering the box.

[0058] In order to ensure the normal and orderly operation of the power cylinder, the box is installed with an air source 600.

[0059] When the entire device is in use, the gun cleaning machine first moves to the wire cutting mechanism, and the movable shearing knife swings to the fixed shearing knife to complete the shearing of the welding wire; after the wire cutting is completed, the welding gun moves to the clamping mechanism, and the welding gun is clamped by two clamping arms; after the positioning and progressive advancement of the welding gun are completed, the lifting power part drives the rotating power part equipped with the reamer to rise vertically to the specified position, the pneumatic motor starts, and the rotating reamer cleans the welding gun; after the reamer is cleaned, the clamping arm retreats, the welding gun moves to the oil nozzle, and the welding gun is sprayed with oil through the oil nozzle, thereby completing the wire cutting, reamer cleaning and oil spraying of the welding gun through the semi-automatic gun cleaning machine.

[0060] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one 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.
