[0031] Now, the present utility model will be further described in detail with reference to the accompanying drawings and embodiments. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model. Embodiment 1

[0032] As Figure 11 shown, the product 9 in the present utility model includes a central circular tube 91, a sheet metal part 92, a base 93, a box body 94, and a rib plate 95. The central circular tube 91 is fixedly penetrated through the base 93, and they are perpendicular to each other. The sheet metal parts 92 are distributed in a circumferential array outside the central circular tube 91. The box body 94 is buckled on the base 93 and covers the outside of the central circular tube 91 and the sheet metal parts 92. The rib plate 95 is perpendicular to the side wall of the box body 94 and the base 93 and is located at the middle position between the two.

[0033] As Figures 1-4 shown, a precision part welding tool for a semiconductor packaging device includes a first bottom plate 1 and a support mechanism 2. A positioning hole 11 is provided on the first bottom plate 1, and multiple support mechanisms 2 are arranged and surround the outside of the positioning hole 11. The central circular tube 91 is placed on the first bottom plate 1 through the positioning hole 11, and the sheet metal part 92 is clamped by the support mechanism 2 so that one end thereof contacts the outer side surface of the central circular tube 91, facilitating the welding work between the two.

[0034] As described above, multiple groups of limit pins 13 for defining the position of the base 93 are provided on the first bottom plate 1. The base 93 is fixedly connected to the central circular tube 91, and a material taking groove 12 for taking the base 93 is also provided on the first bottom plate 1. The limit pins 13 are grouped in pairs and distributed outside the four corners of the base 93. When the base 93 is placed on the first bottom plate 1, one end of the central circular tube 91 just fits into the positioning hole 11. At this time, the base 93 covers half of the material taking groove 12, that is, when taking the material, it can be inserted into the lower part of the base 93 through the uncovered half of the material taking groove 12, facilitating picking it up.

[0035] The supporting mechanism 2 includes a supporting block 21, a limiting insertion piece 22 and an adjusting component 23. The supporting block 21 is fixedly installed on the first bottom plate 1. The limiting insertion piece 22 passes through the supporting block 21 and is parallel to the first bottom plate 1. A clamping groove 221 is formed at one end of the limiting insertion piece 22 close to the positioning hole 11. The clamping groove 221 is in the middle position and is used for clamping the sheet metal part 92. That is, under the combined action of the supporting block 21 and the limiting insertion piece 22, one end of the sheet metal part 92 is embedded in the clamping groove 221, and the other end is in contact with the outer circumferential surface of the central circular tube 91.

[0036] The central circular tube 91 is fixed on the first bottom plate 1 through the positioning hole 11. The supporting mechanism 2 clamping the sheet metal part 92 is distributed outside the positioning hole 11, and one end of the sheet metal part 92 can be firmly attached to the outer side surface of the central circular tube 91 for welding. The sheet metal part 92 is inserted into the end of the limiting insertion piece 22 through the clamping groove 221. It is convenient to take and place, can reduce the extra operation time, ensure the quality of the product 9, and improve the welding precision and efficiency.

[0037] As described above, the supporting block 21 is also provided with insertion holes 211 corresponding to the quantity and positions of the limiting insertion pieces 22. The limiting insertion pieces 22 pass through the supporting block 21 through the insertion holes 211. The adjusting component 23 can adjust the extending length of the limiting insertion piece 22, and the adjusting component 23 is arranged on one side of the insertion hole 211. By adjusting the extending length of the limiting insertion piece 22 relative to the positioning hole 11 through the adjusting component 23, the tooling can be adapted to weld sheet metal parts 92 of different sizes, greatly improving the application range of the tooling.

[0038] Wherein, two limiting insertion pieces 22 are arranged on each supporting block 21, and the two limiting insertion pieces 22 are distributed up and down in parallel on the supporting block 21. Two limiting insertion pieces 22 are arranged on each supporting block 21, which can position and clamp the sheet metal part 92 from the upper and lower positions, ensuring that its position relative to the positioning hole 11 is more accurate and the clamping is more stable.

[0039] The width of the clamping groove 221 is the same as the thickness of the sheet metal part 92. The depth of the clamping groove 221 is less than the width of the sheet metal part 92, and the distance between the two limiting insertion pieces 22 is less than the height of the sheet metal part 92.

[0040] As Figures 4-5 shown, the adjusting component 23 includes a mounting hole 231, a fastening piece 232 and a limiting groove 222. The limiting groove 222 is formed on the limiting insertion piece 22. The mounting hole 231 is arranged on one side of the insertion hole 211, and one end of the fastening piece 232 is embedded in the mounting hole 231. A gasket 233 is sleeved on the fastening piece 232, and one end of the gasket 233 extends into the limiting groove 222 and abuts against its end face.

[0041] Specifically, the mounting hole 231 is opened on the support block 21 and is a threaded hole. The fastener 232 is a screw, and the gasket 233 is in an annular structure. The limiting groove 222 is opened on the edge of the limiting insert 22. One end of the fastener 232 is screwed into the mounting hole 231 to facilitate fixing the gasket 233 on the support block 21, and one end of the gasket 233 can extend into the limiting groove 222, and its end face contacts the end face of the limiting groove 222, then the limiting insert 22 can be fixed on the support block 21.

[0042] Wherein, the limiting groove 222 is perpendicular to the support block 21. One end of the gasket 233 is located between the side face of the support block 21 and the side face of the limiting groove 222, and the number of gaskets 233 can be increased or decreased as needed to adjust the protruding length of the limiting insert 22 relative to the positioning hole 11. Embodiment 2

[0043] As Figure 2 、 Figures 6-7 shown, on the basis of Embodiment 1, when there are four sheet metal parts 92 on the outer side of the central circular tube 91 and the four sheet metal parts 92 are circumferentially arrayed around the axis of the central circular tube 91, due to the interference of the base 93, three support mechanisms 2 are provided, and the three support mechanisms 2 are distributed in a triangular pattern outside the positioning hole 11; that is, first, three of the outer sheet metal parts 92 are fixedly welded, and then the last inner sheet metal part 92 is welded. Based on this, the butt-welding tooling further includes two parallel limiting insertion plates 4 to ensure the dimensional accuracy of the central circular tube 91 and the sheet metal parts 92.

[0044] One side of the limiting insertion plate 4 is provided with a groove 41 corresponding to the outer contour of the central circular tube 91, and three clamping openings 42 for clamping the sheet metal parts 92 are opened in the groove 41, and the three clamping openings 42 are distributed in a triangular pattern.

[0045] After three of the sheet metal parts 92 are welded, the support mechanism 2 is removed, the sheet metal part 92 to be welded is inserted into the middle clamping opening 42, and the limiting insertion plate 4 is axially sleeved on the sheet metal part 92, so that two opposite sheet metal parts 92 on the central circular tube 91 are respectively embedded into two opposite clamping openings 42. At this time, the groove 41 and the side face of the sheet metal part 92 to be welded are in contact with the outer circumferential surface of the central circular tube 91, and then the welding work of the fourth sheet metal part 92 is carried out.

[0046] As described above, the two limiting insertion plates 4 are respectively located at the upper and lower parts of the sheet metal part 92, which is equivalent to the two limiting inserts 22 in the support mechanism 2; a cover plate 3 is fixedly installed above the limiting insertion plate 4 located at the upper part, and the limiting insertion plate 4 can be fixed at the upper part of the sheet metal part 92 through the cover plate 3; and a handle 5 is fixedly installed on the cover plate 3, and it is convenient to take it through the handle 5. Embodiment 3

[0047] Based on Embodiments 1 and 2, for the welding of the rib plate 95 between the base 93 and the box body 94, the present utility model further proposes a positioning mechanism for positioning the rib plate 95 between the base 93 and the box body 94.

[0048] As Figures 8-10 shown, the box body 94 is sleeved outside the central circular tube 91 and the sheet metal part 92 and fixedly connected to the base 93, and the rib plate 95 is located at the middle position between the box body 94 and the base 93.

[0049] The positioning mechanism includes clamping blocks 61, limiting blocks 62, supporting blocks 63, a bracket 7 and a stop block 8 arranged on the second bottom plate 6. The second bottom plate 6 is parallel to the first bottom plate 1. The first bottom plate 1 and the second bottom plate 6 can be installed on the same workbench to assist in fixing different parts of the product 9 during welding, and here the base 93 is perpendicular to the second bottom plate 6.

[0050] There are two clamping blocks 61, two limiting blocks 62 and two stop blocks 8. The two clamping blocks 61 are distributed on both sides of the end of the box body 94 far from the base 93. The two limiting blocks 62 are oppositely arranged on the side of the box body 94 far from the rib plate 95. The two clamping blocks 61 are parallel to each other and one side of each of them abuts against the bottom surface of the base 93.

[0051] The bracket 7 is used to support the rib plate 95. A pressing block 71 is arranged on its top. One end of the pressing block 71 is connected to the bracket 7 by screws and is used to firmly press the rib plate 95 on the bracket 7. The widths of the closed end and the open end of the box body 94 are different, and the box body 94 is placed on the second bottom plate 6 sideways. Therefore, it is necessary to pad up its lower position through the supporting block 63. The supporting block 63 is arranged below the box body 94 and the base 93 to ensure that the rib plate 95 can be perpendicular to the side surfaces of both the base 93 and the box body 94 at the same time.

[0052] Working principle:

[0053] First, weld the base 93 and the central circular tube 91 together, and then place the base 93 inside the limit pin 13 on the first bottom plate 1 so that the end of the central circular tube 91 is embedded in the positioning hole 11. Adjust the elongation of the limit insert piece 22 through the adjusting assembly 23, insert the sheet metal part 92 into the card slot 221, and make one end of it contact the outer circumferential surface of the central circular tube 91. After welding the three sheet metal parts 92 on the outside, remove the support mechanism 2, and use two limit inserting plates 4 to assist in fixing the last sheet metal part 92 on the outside of the central circular tube 91.

[0054] After the sheet metal part 92 is welded to the central circular tube 91, the box body 94 is buckled on the outside of the central circular tube 91, and the base 93 and the box body 94 are placed on the second base plate 6 together. After being limited by the clamping block 61, the limiting block 62, the supporting block 63 and the stop block 8, the rib plate 95 is placed on the bracket 7, and its two mutually perpendicular end faces are respectively abutted against the side faces of the box body 94 and the base 93, and after being fixed by the pressing block 71, welding is carried out.

[0055] In summary, the welding fixture proposed by the present utility model can reduce the extra operation time, improve the welding efficiency, reduce the error probability, make the precision higher, and ensure the quality of the product 9.
