Description

Technical Field

[0001] The present application belongs to the technical field of thread brazing sealing layer processing, and specifically relates to a valve tapered tube thread brazing sealing layer processing device. Background Art

[0002] Taper pipe thread connection is the most common way of thread sealing, and its characteristics are simple sealing, low cost and wide application. The use of brazing tin layer on the external tapered pipe threads at important parts is an important measure to increase the reliability of thread sealing. However, the thickness of the brazing tin layer is large and the thickness of the tin layer is uneven, which makes it difficult for the nut to be screwed in when the thread is connected. Therefore, there are two different thicknesses of the sealing tin layer of the tapered pipe thread, namely the sealing tin layer for sealing and the screwing tin layer for connection. In other words, two different thread diameters are processed on the same thread. At present, the thickness of the tin layer is controlled by the brazing process, but it has the problem of low processing efficiency and cannot meet the precision requirements. Utility Model Content

In addition, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be a connection between the two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to the specific circumstances.

[0029] like Figures 1 to 7 As shown, the valve tapered pipe thread brazing sealing layer processing device provided by the embodiment of the utility model includes a valve clamping body 2, a cutting tool 4, a drilling machine 3 and a cutting tool shifting block 6.

[0030] The valve clamping body 2 is installed on a tooling table 31 of a drilling machine 3 , and the valve clamping body 2 is used to clamp the lower part of the valve product 1 .

[0031] The cutting tool 4 is arranged above the valve clamping body 2, and a through groove 5 is arranged at the center of the upper end of the cutting tool 4. The hole at the center of the lower end of the cutting tool 4 is provided with a recognition cutting edge 41 and a sealing layer cutting edge 42 from top to bottom. The recognition cutting edge 41 and the sealing layer cutting edge 42 are used for cutting the section to be processed 11 on the upper part of the valve product 1.

[0032] The tool shift block 6 includes a connecting column 61 and a shift bar 62 disposed at the lower end of the connecting column 61 . The shift bar 62 is clamped in the through slot 5 . The connecting column 61 is connected to the overload clamp 32 of the drilling machine 3 .

[0033] It should be noted that when processing the threaded brazing sealing layer, the valve product 1 is clamped by the valve clamp body 2, and the valve product 1 is positioned, and the cutting tool 4, the section to be processed 11 of the valve product 1, and the connecting column 61 of the tool shift block 6 are adjusted so that the axis lines of the three coincide, and the drilling machine 3 is started. The overload chuck 32 of the drilling machine 3 drives the cutting tool 4 to rotate through the tool shift block 6, so that the threaded brazing sealing layer 11 of the valve product 1 is cut, and then the sealing tin layer and the threaded brazing sealing layer are formed until the threaded brazing sealing layer reaches the cutting length, and the product processing is completed. The device can well process the sealing tin layer used for sealing and the threaded tin layer used for connecting and screwing by setting the cutting tool, and it has high processing accuracy and high processing efficiency, so it can meet the needs of processing the threaded brazing sealing layer of the valve tapered pipe.

[0034] The threading cutting edge 41 and the sealing layer cutting edge 42 of this embodiment are a composite of two cutting tools, and are a stepped double thread design, that is, the same thread cutting tool is designed with upper and lower cutting tools of different mid-diameters. The processing device of this embodiment can solve the problem of uneven thickness of the tinning layer of the valve taper pipe thread and the difficulty of screwing the user's nut into the threading, thereby improving work efficiency, reducing labor intensity, and the processed valve thread tinning has a beautiful appearance.

[0035] In this embodiment, a threaded blind hole 43 is provided on one side of the upper end of the cutting tool 4 .

[0036] The tool positioning block 7 includes a horizontal section 71 and a vertical section 72 connected to each other. The hexagonal bolt 8 passes through the hole of the horizontal section 71 and is screwed into the threaded blind hole 43. The vertical section 72 is located in the through groove 5, and the lower end of the vertical section 72 extends into the hole at the center of the lower end of the cutting tool 4.

[0037] It should be noted that when the threaded brazing sealing layer reaches the cutting length, the lower end of the vertical section 72 abuts against the upper end of the section to be processed 11 of the valve product 1, thereby playing a limiting role and achieving the purpose of controlling the cutting length.

[0038] In this embodiment, the lever 62 is in the shape of a long strip, and two sides of the lever 62 are arc surfaces.

[0039] It should be noted that the arc surface is in line contact, while the two sides of the lever 62 are flat surfaces. The lever 62 of this embodiment can reduce the matching accuracy between the lever 62 and the cutting tool 4 .

[0040] In this embodiment, the valve clamp body 2 includes a bottom plate 21 and a left plate 22 and a right plate 23 arranged on both sides of the bottom plate 21. The bottom plate 21, the left plate 22 and the right plate 23 are connected to form a U-shaped structure, and the bottom plate 21 is installed on the tooling table 31 of the drilling machine 3. A positioning groove 211 for positioning the valve product 1 is provided on the front side of the bottom plate 21.

[0041] It should be noted that the valve product 1 can be quickly installed into the positioning groove 211 from the side of the bottom plate 21, so as to achieve the purpose of quick installation and removal, and also achieve the purpose of positioning.

[0042] In this embodiment, fastening bolts 9 are installed on the outer sides of the left side plate 22 and the right side plate 23 .

[0043] A clamping adjustment plate 10 is provided on the inner side of the left plate 22 and the right plate 23 . The upper end of the clamping adjustment plate 10 overlaps the upper end surface of the left plate 22 or the right plate 23 , and the end of the fastening bolt 9 abuts against the corresponding clamping adjustment plate 10 .

[0044] It should be noted that tightening the fastening bolts 9 can push the left plate 22 or the right plate 23 to move toward the valve product 1 , thereby clamping the valve product 1 .

[0045] In this embodiment, the cutting tool 4 is provided with an arc chip groove 44 on the outer side of the upper portion of the cutting edge 41 .

[0046] It should be noted that the arc chip groove 44 is used to accommodate waste chips generated during cutting, ensure the smooth progress of the cutting process, and ensure the cutting angle. The hole in the center of the cutting tool 4 runs through its upper and lower ends, and the width of the through groove 5 is smaller than the diameter of the hole in the center of the cutting tool 4.

[0047] In this embodiment, it is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiment, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiment should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and therefore it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
