Description

Technical Field

[0001] This utility model relates to the field of pipe fitting inner wall cleaning technology, and in particular to a device for cleaning the inner wall of a hardware pipe fitting port. Background Technology

[0002] In the manufacturing process of metal pipe fittings, to meet pipe connection requirements, internal threading operations such as tapping are often required on the inner wall of the port. This cutting and forming process inevitably generates a large number of fine metal chips with sharp edges. Some of these chips will fall off, but a considerable portion will still adhere to or become embedded in the thread grooves and the inner wall surface of the port.

[0003] Currently, the common method for treating metal debris remaining on the inner wall of the port after machining is to clean it with a high-pressure air gun. However, while a high-pressure air gun can remove some loose debris, its effectiveness in removing debris embedded in thread grooves or adhering to cutting fluid or grease is limited. If these metal debris are not effectively removed before connection, they will directly enter the pipeline medium flow, circulate with the fluid, and pose a serious threat to the entire pipeline system. Utility Model Content

[0004] Based on this, the present invention provides a cleaning device for the inner wall of a hardware pipe fitting port. It has a simple structure and is easy to use. The positioning component positions the hardware pipe fitting, and the brush is used to brush the inner wall of the port of the hardware pipe fitting. It can effectively remove debris and stubborn stains adhering to the inner wall of the port. After that, it can be used with a high-pressure air gun for flushing, which can greatly improve the cleaning effect and effectively solve the problem that traditional high-pressure air gun blowing cannot completely remove debris, thus avoiding the threat posed by residual debris to the pipeline system.

Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0015] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0016] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0017] Please see Figures 1 to 5 The present invention provides a hardware pipe fitting port inner wall cleaning device, which includes a base plate 10, a positioning component 20 detachably installed at one end of the base plate 10, and a cleaning component 30 installed at the other end of the base plate 10.

[0018] The bottom surface of the base plate 10 is provided with a plurality of internal threaded holes 11 evenly spaced in the middle, and the internal threaded holes 11 are used to match and connect the positioning component 20.

[0019] The positioning assembly 20 includes a quick-release plate 21 detachably connected to the base plate 10, a positioning pin 22 installed at one end of the top surface of the quick-release plate 21, a support plate 23 fixedly installed at the other end of the top surface of the quick-release plate 21, and a support block 24 adjustablely installed at the top of the support plate 23. The top of the support block 24 is provided with a V-shaped support opening 25, which can accommodate hardware fittings 40 of different sizes and specifications. The positioning pin 22 is used to insert one end of the hardware fitting 40, and the support block 24 is used to support the other end of the hardware fitting 40. Specifically, one end of the hardware fitting 40 is provided with a positioning hole 41 for the positioning pin 22 to be inserted.

[0020] Furthermore, the quick-release plate 21 has through holes (not shown in the figure) at both opposite ends, and these through holes correspond one-to-one with the internal threaded holes 11. T-bolts 26 are threaded through the through holes and then matched with the internal threaded holes 11 to achieve the connection between the quick-release plate 21 and the base plate 10. Through the installation and removal of the quick-release plate 21, it is possible to replace hardware fittings 40 of different sizes and specifications in actual use.

[0021] In this embodiment, as Figure 4 As shown, the top of the support plate 23 has circular holes 230 on opposite sides, and the bottom of the support block 24 has slotted holes 240 on opposite sides, with the slotted holes 240 corresponding to the circular holes 230 one-to-one. Bolts are passed through the circular holes 230 and slotted holes 240, and nuts are then connected to achieve the connection between the support block 24 and the support plate 23. In practical use, the height of the support block 24 can be adjusted by changing the relative position of the support block 24 and the support plate 23 to accommodate hardware fittings 40 of different sizes and specifications.

[0022] The cleaning assembly 30 includes a clamping cylinder 31 installed on one side of each support block 24, a column 32 installed at one end of each support block 24, a cleaning motor 33 installed at the top of each column 32, and a brush 34 coaxially connected to the rotor of each cleaning motor 33; the brush 34 is used to extend into the port of the hardware fitting 40.

[0023] like Figures 1 to 3 As shown, the bottom surface of the pressing block of the pressing cylinder 31 is provided with an inverted V-shaped pressing interface, which is used to better adapt to the circular outer wall of the hardware fitting 40. The pressing cylinder 31 is used to press the hardware fitting 40 to clamp the hardware fitting 40, which facilitates subsequent cleaning operations.

[0024] In this embodiment, the brush 34 and the hardware fitting 40 are arranged coaxially. The brush 34 is used to brush the inner wall of the port of the hardware fitting 40 to effectively remove debris and stubborn stains adhering to the inner wall of the port. After brushing, a high-pressure air gun is used to rinse, which can greatly improve the cleaning effect.

[0025] In this embodiment, the brush 34 is a tapered brush, which makes it easy to insert into hardware fittings 40 of different sizes and specifications.

[0026] The aforementioned cleaning device for the inner wall of the port of the hardware pipe fitting is simple in structure and easy to use. The positioning component 20 positions the hardware pipe fitting 40, and the brush 34 brushes the inner wall of the port of the hardware pipe fitting 40, which can effectively remove debris and stubborn stains adhering to the inner wall of the port. Afterwards, it can be used in conjunction with a high-pressure air gun for flushing, which can greatly improve the cleaning effect and effectively solve the problem that traditional high-pressure air gun blowing cannot completely remove debris, thus avoiding the threat posed by residual debris to the pipeline system.

[0027] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
