Description

Technical Field

[0001] The utility model relates to the technical field of welding gun cleaning equipment, in particular to a novel welding gun cleaning tool. Background Art

[0002] Existing automatic robot arc welding stations generally use copper nozzles. During use, silicone oil needs to be sprayed to prevent welding slag from sticking, and the welding slag attached to the inner wall of the nozzle needs to be manually cleaned at regular intervals. The operation is cumbersome, time-consuming and labor-intensive. At the same time, the nozzle wears out quickly during use, resulting in the cost of consumables for the automatic arc welding station. Existing welding gun cleaning equipment is mostly columnar. For example, application number 202121487233.0 discloses a gun cleaning reamer for cleaning welding gun nozzles. The reamer has a groove on the side. After being inserted into the welding gun, it rotates and uses the groove on the side to contact the welding slag on the inner wall of the welding gun to complete the cleaning. In the actual cleaning process, this reamer has a poor effect on cleaning welding slag for welding guns with a constricted mouth, and cannot effectively clean the deep part of the welding gun, so it needs to be improved. Utility Model Content

[0003] Based on this, it is necessary to provide a new welding gun cleaning tool to address the above problems.

[0004] A novel welding gun cleaning tool comprises a sleeve, wherein a plurality of notched grooves are provided on the side of the sleeve along its axial direction, a plug is detachably mounted on the upper end of the sleeve, a scraper is mounted on the side of the plug, the scraper extends from the notched groove to the outside of the sleeve, and the scraper is retractable along the radial direction of the sleeve.

[0005] Preferably, the scraper blade is in the shape of a semicircular piece.

[0006] Preferably, there are two notch grooves, and two scrapers extend out from the notch grooves in a one-to-one correspondence.

[0007] Preferably, a protrusion is further provided on the side of the plug, and a recess is provided on the inner side of the end of the sleeve corresponding to the protrusion.

[0008] Preferably, a fixing plate is provided at the bottom of the sleeve.

[0009] The utility model is beneficial in that the scraper is retractable so that it always abuts against the inner wall of the welding gun with a constricted opening. When the welding gun and the sleeve rotate relatively, the welding slag of the welding gun with a constricted opening can be cleaned dynamically, and the cleaning effect is excellent.

[0012] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0013] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0014] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0015] like Figures 1-2As shown, the new welding gun cleaning tool comprises a sleeve 1, the side of the sleeve 1 is provided with a plurality of notched grooves 11 along its axial direction, the upper end of the sleeve 1 is detachably mounted with a plug 2, the side of the plug 2 is provided with a scraper 21, the scraper 21 extends from the notched groove 11 to the outside of the sleeve 1, and the scraper 21 is retractable along the radial direction of the sleeve 1. Specifically, the sleeve 1 is made of stainless steel, with high structural strength and low cost, the side of the sleeve 1 is grooved to form the notched groove 11, so that the scraper 21 of the plug 2 can extend from the notched groove 11, the scraper 21 is arranged on the side wall of the plug 2, and the plug 2 is detachably mounted on the top of the sleeve 1, and is used to block the sleeve 1 to prevent the debris from falling into the sleeve 1 when cleaning the welding slag. We set a scraper 21 on the side of the plug 2, and the scraper 21 is connected to the side of the plug 2 through a spring column, so that the scraper 21 can shrink along the radial direction of the sleeve 1. When the welding gun (not shown in the figure) is sleeved outside the sleeve 1, the scraper 21 is constrained by the welding gun, and the spring column connecting the scraper 21 and the plug 2 is compressed. It can be understood that the scraper 21 is tightly pressed against the inner wall of the welding gun under the action of the spring force applied by the spring column. The sleeve 1 or the welding gun is rotated so that the scraper 21 and the welding gun rotate relative to each other, so as to scrape and clean off the welding slag attached to the inner wall of the welding gun, and because the scraper 21 is retractable, the scraper 21 can be retracted and retracted according to the change of the inner diameter when the welding gun is raised and lowered, so that the protruding end of the scraper 21 can always be in contact with the inner wall of the welding gun and contact with the welding slag, thereby dynamically completing the cleaning of the welding slag of the shrinking welding gun, and the cleaning effect is excellent. The scraper 21 is in the shape of a semicircle. When the welding gun is sleeved on the outer side of the sleeve 1 from top to bottom, the scraper 21 contacts smoothly without getting stuck, ensuring that the scraper 21 will not be affected by the welding slag and get stuck in the welding gun when the welding gun is raised and lowered to remove slag.

[0016] Specifically, in this embodiment, the number of the notch grooves 11 is two, and the two scrapers 21 extend from the notch grooves 11 one by one. In other embodiments, scrapers 21 corresponding to other numbers of notch grooves 11 can also be designed, but they cannot be densely spaced to avoid clogging between the inner wall of the welding gun and the outer wall of the sleeve 1.

[0017] like Figure 2 As shown, the side of the plug 2 is also provided with a protrusion 22, and the inner side of the end of the sleeve 1 is provided with a recessed portion 12 corresponding to the protrusion 22. Specifically, in this embodiment, the protrusion 22 cooperates with the recessed portion 12 to lock the plug 2, and at the same time facilitates the disassembly and assembly of the plug 2 and the cleaning of the welding slag dropped in the sleeve 1.

[0018] like Figures 1-2 As shown, a fixing plate 13 is provided at the bottom of the sleeve 1 for fixing the sleeve 1 on the machine platform, and removing the welding slag attached to the inner wall of the welding gun by rotating the welding gun.

[0019] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
