Technical Field
[0001] This utility model relates to the field of weld cleaning equipment, and in particular to a weld cleaning brush structure. Background Technology
[0002] Chinese patent document CN218251644U discloses a technical solution entitled "A Treatment Gun for a Weld Bead Cleaning Machine," which includes the following technical features: a gun body, a connecting pipe, a brush head, a positioner, an insulating layer, brush bristles, etc. In actual use, the cleaning fluid flows directly from inside the gun onto the brush bristles. Because the treatment gun lacks any module for collecting the cleaning fluid or removing fumes, waste fluid and residue generated during the brush cleaning process remain on the workpiece surface. This necessitates an additional step of cleaning the workpiece surface, resulting in excessively long cleaning times. Furthermore, the generated fumes disperse around the workpiece, causing environmental pollution and potentially affecting the health of operators. While some solutions have incorporated suction ports into the treatment guns of weld bead cleaning machines, these solutions suffer from problems such as unreasonable port placement, poor suction capacity, prolonged cleaning time, and health risks. Therefore, it is essential to design a weld bead cleaning brush structure to address these technical issues. Utility Model Content

[0026] like Figures 1 to 3As shown, the weld cleaning brush structure of this utility model includes a cleaning tube head 1 and brush bristles 2. A liquid outlet hole 10 is provided on one end face of the cleaning tube head 1, and one end of the brush bristles 2 is embedded in the liquid outlet hole 10. A suction port 20 arranged around the liquid outlet hole 10 is also provided on one end face of the cleaning tube head 1.
[0027] In this weld bead cleaning brush structure, not only is an outlet hole 10 provided on the end face of the cleaning tube head 1, but an intake port 20 is also provided on the end face of the cleaning tube head 1, arranged around the outlet hole 10. Furthermore, one end of the brush bristles 2 is embedded in the outlet hole 10. Thus, the intake port 20 is arranged around the brush bristles 2, and the intake port 20 and the brush bristles 2 are located on the same end face. This weld bead cleaning brush structure achieves excellent suction effect regardless of the brushing direction. The overall structure of this weld bead cleaning brush is very reasonable and reliable, enabling the intake port 20 to achieve a comprehensive and effective suction effect during the cleaning process of the weld bead by the brush bristles 2. This facilitates the rapid and effective removal of fumes, preventing workers from inhaling them and better protecting their health. Moreover, the intake port 20 can also be used to remove waste liquid and slag, eliminating the need for workers to clean the workpiece subsequently, which helps to shorten the weld bead cleaning time.
[0028] The inhalation port 20 can be one or multiple; when there is one, it is cylindrical so that it surrounds the liquid outlet 10; when there are multiple, each inhalation port 20 surrounds the liquid outlet 10, and the distance between adjacent inhalation ports 20 is kept as small as possible (controlled to be less than 2mm); in this way, the inhalation port 20 can produce a comprehensive and effective inhalation effect.
[0029] In actual manufacturing, the brush bristles 2 loosely fill the liquid outlet 10. The cleaning fluid discharged from the outlet 10 keeps the brush bristles 2 moist and ensures that a suitable amount of cleaning fluid is sprayed onto the weld bead. This allows the weld bead to be cleaned by the cleaning fluid and the tip of the brush bristles 2 working together. This not only meets normal cleaning needs but also prevents the suction inlet 20 from directly drawing in the cleaning fluid, thus ensuring a smooth and stable weld bead cleaning process. When brushing with the tip of the brush bristles 2, the suction inlet 20 is in a higher position, which prevents the suction inlet 20 from directly drawing in the cleaning fluid, while still meeting the needs for normal smoke extraction. The suction inlet 20 can also remove waste liquid and residue.
[0030] In practical use, this weld cleaning brush structure is applied to a weld cleaning machine to supply cleaning fluid. The weld cleaning machine has an air intake and filter module, which is connected to the intake port 20 to filter and collect fumes, waste liquid, and waste residue, thereby meeting the normal weld cleaning needs.
[0031] like Figure 2and Figure 3 As shown, the cleaning head 1 includes a liquid supply tube 11 and an air suction tube 12. The liquid supply tube 11 is disposed within the air suction tube 12. An air suction gap 30 is reserved between the outer wall of the liquid supply tube 11 and the inner wall of the air suction tube 12. The suction port 20 is formed between the port of the air suction tube 12 and the port of the liquid supply tube 11 and communicates with the air suction gap 30. The inner hole of the liquid supply tube 11 constitutes the liquid outlet 10. This cleaning head 1 is very simple and reliable. It is not only easy to manufacture, but also ensures excellent liquid supply and air suction performance, thereby helping to further improve the reliability and applicability of the weld cleaning brush structure.
[0032] like Figure 3 and 4 As shown, the liquid supply tube body 11 includes a liquid supply front tube 111 and a liquid supply rear tube 112, and the air intake tube body 12 includes an air intake front tube 121 and an air intake rear tube 122. The input end of the liquid supply rear tube 112 is placed in the air intake rear tube 122. A rear suction gap 301 is reserved between the outer wall of the liquid supply rear tube 112 and the inner wall of the air intake rear tube 122. The liquid supply front tube 111 is directly or indirectly threaded onto the output end of the liquid supply rear tube 112. The inner hole of the liquid supply front tube 111 and the inner hole of the liquid supply rear tube 112 together form the liquid outlet 10. One end of the brush bristles 2 is embedded in the liquid supply front tube 111, and the brush bristles 2 are connected to the liquid supply rear tube. 112 are directly or indirectly connected. The inhalation tube 121 is slidably fitted or embedded on the inhalation tube 122, and the inhalation tube 121 is fitted on the liquid supply tube 111. The inner wall of the inhalation tube 121 is fixedly connected to the outer wall of the liquid supply tube 111. A front suction gap 302, which communicates with the rear suction gap 301, is reserved between the outer wall of the liquid supply tube 112 and the inner wall of the inhalation tube 121. The front suction gap 302 and the rear suction gap 301 together constitute the inhalation gap 30. The suction port 20 is formed between the outer wall of the liquid supply tube 111 and the inner wall of the inhalation tube 121 and communicates with the front suction gap 302. This allows the front suction pipe 121 to rotate, causing the front liquid supply pipe 111 to move back and forth. This adjusts the amount of bristles 2 exposed above the liquid supply pipe 111, ensuring that the bristles 2 are exposed to a suitable length even after wear, and also facilitating adjustment of the exposed bristle length according to different cleaning needs. This better meets various usage environments and improves the applicability of the weld bead cleaning brush structure. Furthermore, during rotation, the front suction pipe 121 slides on the rear suction pipe 122, ensuring that the front suction gap 302 and the rear suction gap 301 remain connected, thus guaranteeing very stable suction performance and high reliability of the weld bead cleaning brush structure.
[0033] The intake pipe 121 can be made into a variable diameter pipe, which not only enables excellent assembly but also controls the overall size, thereby achieving the goal of controlling manufacturing costs.
[0034] like Figure 5 and Figure 6 As shown, at least one thin connecting piece 101 is provided between the outer wall of the liquid supply pipe 111 and the outer wall of the suction pipe 121 to fix the liquid supply pipe 111 and the suction pipe 121 together. This can meet the needs of actual manufacturing and adjustment operations.
[0035] like Figures 2 to 4 As shown, an adapter 113 is fitted onto the output end of the liquid supply tube 112. The brush bristles 2 are connected to the adapter 113, and the liquid supply tube 111 is threaded onto the adapter 113. The adapter 113 provides a protruding threaded connection for the suction tube 121, eliminating the need for long threads on the outer wall of the liquid supply tube 111 to adjust the amount of brush bristles 2 exposed. This reduces manufacturing difficulty and improves reliability.
[0036] like Figures 2 to 4 As shown, the adapter 113 is threaded onto the liquid supply pipe 112. This not only meets the requirements for stable installation but also facilitates disassembly and maintenance, and allows for easy matching with other sizes of liquid supply pipes 111, thereby helping to further improve the reliability and applicability of the weld cleaning brush structure.
[0037] like Figures 2 to 4 As shown, the output end of the liquid supply pipe 112 protrudes beyond the suction end of the suction pipe 122, and the adapter pipe 113 is threadedly fitted onto the output end of the liquid supply pipe 112 that protrudes from the suction pipe. This not only facilitates the stable installation of the adapter pipe 113, but also allows the adapter pipe 113 to be located outside the suction pipe 122, thereby facilitating the installation, removal, and maintenance of the adapter pipe 113, and further improving the reliability and applicability of the weld cleaning brush structure.
[0038] like Figures 2 to 4 , Figure 7 and Figure 8 As shown, a protruding tube portion 114 is provided on the end face of the adapter 113 away from the liquid supply pipe 112. A positioning tube 115 is fitted onto the protruding tube portion 114. The brush bristles 2 are clamped by the end of the positioning tube 115 away from the protruding tube portion 114. A liquid supply hole 116 is provided on the outer wall of the positioning tube 115, which communicates with the liquid supply pipe 112 through the adapter 113. This not only facilitates a stable and reliable connection between the brush bristles 2 and the adapter 113, but also prevents the brush bristles 2 from affecting the installation, positioning, and adjustment of the liquid supply pipe 111, thereby helping to further improve the reliability and applicability of the weld cleaning brush structure.
[0039] like Figure 2 , Figure 3 , Figure 7 and Figure 9 As shown, a positioning annular groove 117 is formed on the outer circumferential surface of the convex tube portion 114, and a positioning spring 118 is fitted onto the positioning annular groove 117. An annular groove 119 is formed on the inner wall of the positioning tube 115, and the annular groove 119 is detachably fitted onto the positioning spring 118. This facilitates the installation and removal of the positioning tube 115, thereby facilitating the installation and removal of the brush bristles 2, and improving the convenience of replacing and maintaining the brush bristles 2. Furthermore, this provides a very stable and reliable positioning effect for the brush bristles 2, thus contributing to the stability and reliability of the brush bristle installation and positioning. This further enhances the reliability and applicability of the weld cleaning brush structure.
[0040] like Figure 8 As shown, a clamping piece 1151 is formed in the recessed wall of the positioning tube 115 at the end away from the convex tube 114. The liquid supply hole 116 is located on the side wall of the clamping piece 1151, and the ends of the brush bristles 2 are clamped by the clamping piece 1151 and the inner wall of the positioning tube 115. This not only facilitates and stably positions the brush bristles 2, but also enables the liquid supply hole 116 to accurately supply liquid to the brush bristles 2, thereby helping to further improve the reliability and applicability of the weld cleaning brush structure.
[0041] like Figure 1 and Figure 2 As shown, the liquid supply pipe 112, the adapter pipe 113, and the positioning pipe 115 are all metal tubes, and a wire (not shown in the figure) is connected to the liquid supply pipe 112. This not only gives the liquid supply pipe 112, the adapter pipe 113, and the positioning pipe 115 high structural strength and durability, but also meets the requirements for electrical conductivity and liquid cooling, thereby fulfilling the need for electrolytic cleaning of weld beads. This further helps to improve the versatility of cleaning, which in turn helps to further improve the reliability and applicability of the weld bead cleaning brush structure.
[0042] like Figure 7 As shown, the adapter 113 and the convex tube 114 are an integral structure. The brush bristles 2 are made of carbon fiber, which not only makes the brush bristles 2 highly durable, but also conducts electricity, thereby facilitating a better electrolytic cleaning effect.
[0043] The wire can be fixed to the liquid supply pipe 112 by welding, screw tightening, clamping, bundling, etc., so as to meet the actual manufacturing needs.
[0044] The liquid supply tube 112 is made of brass, copper, or stainless steel, the positioning tube 115 is made of copper, and the adapter tube 113 is made of stainless steel. This not only perfectly meets the requirements of conductivity and electrolytic cleaning, but also facilitates the processing of the positioning tube 115. Furthermore, the stainless steel adapter tube 113 prevents direct contact between the copper liquid supply tube 112 and the positioning tube 115, thus avoiding corrosion between the copper tubes and the resulting inability to disassemble. This facilitates subsequent disassembly and maintenance, further improving the applicability of the weld cleaning brush structure.
[0045] like Figures 1 to 4 As shown, an insulated handle 4 is provided on the other end of the cleaning tube head 1. This not only facilitates worker operation but also improves operational safety.
[0046] The above embodiments are preferred embodiments of this utility model. All structures similar to this utility model and equivalent changes thereof should fall within the protection scope of this utility model.
