[0002] TIG (Tungsten Inert Gas Weiding) welding is a welding method that, under the protection of an inert gas, generates an electric arc in the welding area to heat and melt the metal and the filler material.

[0003] When performing TIG welding, an arc welding torch is used. During welding, the tungsten needle in the arc welding torch needs to extend a certain length. During the long-term welding process, the welding tungsten needle will experience wear and passivation problems. It is necessary to remove the tungsten needle and grind it to ensure that the discharge point of the tungsten needle is in the same position. After grinding, it is necessary to adjust the distance between the tungsten needle and the welded part. Further, it is necessary to readjust the extended length of the tungsten needle after installation.

[0004] In the related art, after grinding the tungsten needle, while installing, the extended length of the tungsten needle is measured with a caliper and then adjusted appropriately until the adjustment is appropriate. This adjustment method is relatively inconvenient and has a large error.

[0005] In summary, how to provide a device that is convenient for adjusting the extended length of the tungsten needle is an urgent problem to be solved by those skilled in the art at present. Content of the Utility Model

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0032] The core of the present invention is to provide a black needle positioning and installation device, which can quickly and efficiently adjust the protruding length of the ground black needle to the required position, improving the efficiency and accuracy of the adjustment.

[0033] The black needle positioning and installation device provided by the present invention includes a limit seat 7, a black needle insertion block 4, and a black needle clamping member 01. Please refer to Figures 1-2 .

[0034] The black needle insertion block 4 is arranged opposite to the limit seat 7 and is used for inserting the black needle 9. The black needle clamping member 01 abuts against the black needle insertion block 4 and is used for installing the black needle 9. After the black needle 9 is installed in the black needle clamping member 01, it extends out a certain length, and the extended part passes through the black needle insertion block 4 and abuts against the limit seat 7.

[0035] The black needle clamping member 01 is used for installing the black needle 9. Specifically, its internal cavity is used for installing the black needle 9. The black needle 9 can move in the internal cavity of the black needle clamping member 01 or can be locked on the black needle clamping member 01.

[0036] When specifically in use, when the black needle 9 has problems of wear and passivation and needs to be ground, it is first removed from the black needle clamping member 01, and the black needle 9 can be ground separately; after the grinding operation is completed, the black needle 9 is inserted into the internal cavity of the black needle clamping member 01 and extends out a certain length. At this time, the two are not locked. Further, move the extended part of the black needle 9 so that it passes through the black needle insertion block 4 and its tail abuts against the limit seat 7. At this time, the black needle 9 is in place.

[0037] After that, the black needle 9 remains stationary, and the black needle clamping member 01 is moved until its tail abuts against the front side wall of the black needle insertion block 4. The black needle clamping member 01 is in place. At this time, the black needle 9 can be locked by the black needle clamping member 01. At this time, the length of the black needle 9 extending out of the black needle clamping member 01 is equivalent to the distance between the front side wall of the black needle insertion block 4 and the limit seat 7. This distance is actually a fixed value. Therefore, the extended length can be guaranteed to be a constant value whether before or after the black needle is ground.

[0038] Please refer to Figure 1 In the above process, the rear side wall of the black needle insertion block 4 is the side wall close to the limit seat 7, and the front side wall of the black needle insertion block 4 is the side wall far from the limit seat 7.

[0039] In this embodiment, if it is necessary to change the extended length of the black needle 9 extending out of the black needle clamping member 01, the distance between the front side wall of the black needle insertion block 4 and the limit seat 7 can be changed. At least one of the black needle insertion block 4 and the limit seat 7 can move in the length direction of the base 1; after adjusting the distance between the front side wall of the black needle insertion block 4 and the limit seat 7, the adjusted distance is used as a fixed value to guide the installation of the black needle after subsequent grinding.

[0040] Optionally, for the convenience of adjusting the distance between the front side wall of the black needle insertion block 4 and the limit seat 7, a scale value can be set on the base 1 to facilitate quickly knowing the adjusted distance.

[0041] In this embodiment, the limit seat 7 can be in the form of a fixed plate or in the form of a cylinder, which can play a role in limiting the movement of the tail of the black needle 9 and provide a limiting reference.

[0042] Preferably, to ensure the accurate installation of the black needle 9, the black needle clamping member 01, the black needle insertion block 4, and the limit seat 7 can be kept concentric to ensure the accurate alignment during the installation of the black needle 9 and the black needle clamping member 01.

[0043] Preferably, the limit seat 7 and the black needle insertion block 4 are arranged on a fixed seat, which is convenient for their relative arrangement to provide the stability and reliability of the reference for adjusting the protruding length of the black needle 9. Specifically, they are detachably connected to the fixed seat, and the detachable method is not limited. For example, with the help of fasteners such as bolts and nuts, the stability and reliability after their connection can be ensured.

[0044] The above black needle positioning and installation device includes a limit seat 7, a black needle insertion block 4, and a support table. The black needle insertion block 4 is arranged opposite to the limit seat 7. The black needle clamping member 01 abuts against the black needle insertion block 4 and is used to place the black needle 9 inside. During specific use, the black needle 9 is inserted into the black needle clamping member 01 and passes through the rear side wall of the black needle insertion block 4 to abut against the limit seat 7. At this time, the black needle clamping member 01 is made to abut against the front side wall of the black needle insertion block 4 and lock the black needle 9. At this time, the length of the black needle 9 protruding from the black needle clamping member 01 is restricted by the distance between the limit seat 7 and the black needle insertion block 4, so that even if the black needle is installed multiple times, the protruding length of the black needle can always be restricted to a certain value. The above black needle positioning and installation device can adjust the length of the black needle protruding from the black needle clamping member to a constant value after grinding the black needle, with simple and fast adjustment, improving the efficiency and accuracy of adjustment.

[0045] On the basis of the above embodiment, the limit seat 7 is movably arranged on the base 1 to change the length of the black needle 9 protruding from the black needle clamping member.

[0046] In this embodiment, the limit seat 7 is movably arranged on the base 1. By using a slide rail and slider structure or by providing multiple connection holes on the base 1, the connection position of the limit seat 7 on the base 1 can be changed, so as to change the distance between the limit seat 7 and the black needle insertion block 4.

[0047] By changing the distance between the limit seat 7 and the black needle insertion block 4, in essence, it is to change the length of the black needle 9 protruding from the black needle clamping member 01 after the black needle clamping member 01 abuts against the front side wall of the black needle insertion block 4.

[0048] When the limit seat 7 moves, a scale for easily reading the moving distance of the limit seat 7 can be set on the base 1, so as to timely obtain the change in the length of the black needle 9 protruding from the black needle clamping member 01.

[0049] On the basis of any of the above embodiments, the limit seat 7 is a differential head, and the measuring rod of the differential head is movably arranged on the base 1 for changing the distance between the measuring rod and the black needle insertion block 4.

[0050] Please refer to Figures 1-3, the limit seat 7 is specifically a differential head, which specifically includes an installation sleeve, a measuring rod, a differential barrel, a bushing, a fine adjustment knob, etc. Among them, the installation sleeve is fixedly installed on the base 1 to support and install the main body of the differential head. The fine adjustment knob is connected to the differential barrel. When the differential barrel or the fine adjustment knob is rotated by hand, the front-end measuring rod can move along the axial direction, and the moving distance can be read through the scales on the differential barrel and the bushing, so as to know the specific adjustment degree of the extension length of the black needle 9.

[0051] The limit seat 7 is specifically set as a differential head, so that the extension length of the black needle 9 extending out of the black needle clamping member 01 can be accurately adjusted, and the adjustment accuracy can reach ±0.02 mm.

[0052] In this embodiment, if some components are offset or worn to a certain extent due to long-term operation, fine adjustment can be performed through the differential head to ensure the accuracy of controlling the extension length of the black needle 9.

[0053] On the basis of any of the above embodiments, an installation bracket 3 for the differential head is provided on the base 1, and the installation hole of the installation bracket 3 is coaxially arranged with the insertion hole of the black needle insertion block 4.

[0054] Please refer to Figure 2 , Figure 3 , the installation bracket 3 is connected to the base 1, preferably in a detachable connection. The installation sleeve of the differential head is specifically fixed on the installation hole of the installation bracket 3. After the installation sleeve is inserted into the installation hole, it fits tightly with the inner wall of the hole to ensure the stability of the installation sleeve and further ensure the reliable support and fixation of the whole differential head.

[0055] The installation hole of the installation bracket 3 is coaxially arranged with the insertion hole of the black needle insertion block 4. Specifically, the axis of the measuring rod of the differential head and the axis of the black needle 9 are collinear, ensuring the coaxiality of the two when the black needle 9 abuts against the measuring rod and ensuring the accuracy of adjusting the extension length of the black needle 9.

[0056] On the basis of any of the above embodiments, the black needle clamping member 01 includes a black needle clamping column 2 and a black needle installation column 8, and the black needle clamping column 2 is connected to the black needle installation column 8 to lock the black needle 9 in the black needle installation column 8.

[0057] Please refer to Figures 1-2 , the black needle clamping member 01 includes a black needle clamping column 2 and a black needle installation column 8, and the two are connected to lock the black needle 9.

[0058] Specifically, the black needle clamping column 2 and the black needle installation column 8 are threadedly connected. When the two are tightened relative to each other, the black needle 9 in the black needle installation column 8 can be pressed to limit the movement of the black needle 9, realizing the locking of the black needle 9 and the black needle clamping member 01.

[0059] Optionally, a deformable pressure ring can be provided between the connection parts of both the wootz needle clamping column 2 and the wootz needle mounting column 8. When the wootz needle clamping column 2 is tightened relative to the wootz needle mounting column 8, the circumference of the pressure ring is compressed to clamp the wootz needle 9.

[0060] In the case where the wootz needle 9 moves, the wootz needle clamping column 2 and the wootz needle mounting column 8 can be connected but not fully tightened. After the wootz needle 9 penetrates into both of them and the protruding length is determined, the two can be locked by tightening to clamp the wootz needle 9.

[0061] Based on any of the above embodiments, the insertion hole is provided in the middle of the wootz needle insertion block 4, and the diameter of the insertion hole is smaller than the outer diameter of the wootz needle mounting column 8.

[0062] Please refer to Figures 1-2 , the insertion hole of the wootz needle insertion block 4 is provided in the middle of the wootz needle insertion block 4 to ensure better stability and reliability. The middle here is only the middle position in a relative sense and can also be a position near the middle position.

[0063] The diameter of the insertion hole is smaller than the outer diameter of the wootz needle mounting column 8, so that the wootz needle mounting column 8 can abut against the front side wall of the wootz needle insertion block 4 for positioning, ensuring quick and effective adjustment of the protruding length of the wootz needle 9. In addition, the diameter of the insertion hole is equal to or slightly larger than the length of the wootz needle 9, facilitating the wootz needle 9 to penetrate through the rear side wall of the wootz needle insertion block 4.

[0064] Based on any of the above embodiments, a support platform is provided on the base 1, and an arc-shaped groove for mounting the wootz needle clamping member 01 is provided on the support platform. The center of the arc-shaped groove and the center of the limit seat 7 are on the same straight line.

[0065] Please refer to Figure 2 , one, two or three support platforms can be provided, specifically depending on the usage requirements of the wootz needle clamping member 01. An arc-shaped groove for supporting the mounting of the wootz needle clamping member 01 is provided on the support platform. The center of the arc-shaped groove and the center of the limit seat 7 are on the same straight line, that is, the center of the wootz needle clamping member 01 and the center of the limit seat 7 are on the same straight line. Further, the insertion hole of the wootz needle insertion block 4 and the center of the wootz needle clamping member 01 are also on the same straight line, enabling the wootz needle 9 to have a high installation accuracy during adjustment and installation, facilitating quick and accurate installation and improving the installation efficiency.

[0066] Optionally, the arc-shaped groove in this embodiment is provided based on the wootz needle clamping member 01 being a cylindrical structure. If it is not a cylindrical structure, it can be adjusted flexibly according to the actual situation.

[0067] Based on any of the above embodiments, the support platform includes a first concentric bracket 5 for supporting the wick needle mounting post 8 and a second concentric bracket 6 for supporting the wick needle clamping post 2. Both the first concentric bracket 5 and the second concentric bracket 6 are coaxially arranged with the insertion hole of the wick needle insertion block 4. Specifically, the mounting hole positions for mounting the wick needle 9 on both the first concentric bracket 5 and the second concentric bracket 6 are coaxially arranged with the insertion hole of the wick needle insertion block 4, ensuring the coaxiality during the installation of the wick needle.

[0068] Please refer to Figures 1-2 , Figure 4 , the support platform includes a first concentric bracket 5 and a second concentric bracket 6. Among them, the specific positions where the two concentric brackets are fixed on the base 1 can be set according to the actual situation without limitation.

[0069] The first concentric bracket 5 is used to support the wick needle mounting post 8, and the second concentric bracket 6 is used to support the wick needle clamping post 2. The structural forms of the two concentric brackets can be determined according to the structural form of the specific wick needle clamping member 01, and there is no limitation on the consistency of the two structures.

[0070] Substantially, during use, both the first concentric bracket 5 and the second concentric bracket 6 jointly support the connected wick needle mounting post 8 and wick needle clamping post 2. After providing support, the wick needle mounting post 8 and the wick needle clamping post 2 can be moved along the length direction of the base 1, so that the wick needle mounting post 8 quickly and accurately abuts against the front side wall of the wick needle insertion block 4 to complete positioning, and further position the wick needle 9 on the measuring rod of the differential head, lock the wick needle mounting post 8 and the wick needle clamping post 2 to lock the wick needle 9, and complete the quick and accurate adjustment of the protruding length of the wick needle 9.

[0071] Based on any of the above embodiments, both the first concentric bracket 5 and the second concentric bracket 6 are provided with mounting positioning holes, and the top opening of the mounting positioning hole is larger than its bottom opening.

[0072] Please refer to Figures 1-2 , the bottom of the mounting positioning hole is arc-shaped to facilitate adapting to the columnar structures of both the wick needle mounting post 8 and the wick needle clamping post 2. The top opening of the positioning mounting hole is larger than the size of the arc-shaped groove at the bottom to facilitate the placement and installation of both the wick needle mounting post 8 and the wick needle clamping post 2.

[0073] In addition, an inclined guiding surface is provided on the inner wall surface at the top of the positioning mounting hole to provide a certain guiding for both the wick needle mounting post 8 and the wick needle clamping post 2 to be placed into the positioning mounting hole, so as to improve the installation efficiency of the wick needle 9 and the adjustment efficiency of the protruding length.
