[0038] 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, which only illustrate the basic structure of the present utility model in a schematic manner. Therefore, they only show the components related to the present utility model

[0039] Embodiment 1

[0040] As Figures 1-4 shown, a semiconductor precision pipe fitting welding positioning device includes a horizontally placed base 1. A first positioning component, a second positioning component, and a pressing component are arranged on the base 1, and an adjusting component is also arranged on the first positioning component; the first positioning component is used to limit the degrees of freedom of the pipe fitting, the second positioning component is used to limit the degrees of freedom of the sheet metal part, the pressing component is used to press the pipe fitting and the sheet metal part along the Z-axis direction, so as to firmly fix the two on the base 1, and the adjusting component is used to adjust the straightness of the pipe fitting relative to the sheet metal part; and the first positioning component and the second positioning component are linearly distributed along the X-axis direction, and the pressing component is arranged on the same side of the first positioning component and the second positioning component

[0041] Clamp the pipe fitting with the first positioning component, use the second positioning component and the pipe fitting together to clamp the sheet metal part, and adjust the straightness of the pipe fitting relative to the sheet metal part through the adjusting component. Finally, use the pressing component to firmly press and fix the pipe fitting and the sheet metal part on the base 1; through this device, the extra operation time for clamping the workpiece can be reduced, so as to improve the welding efficiency between the two, and use the adjusting component to ensure the straightness of the pipe fitting, thereby ensuring the welding quality of the product 9

[0042] Among them, the pipe fitting and the sheet metal part are both parts of the product 9, which are equivalent to the bend pipe part 901 and the sheet metal part 902 (as Figure 10 shown). One end of the bend pipe part 901 is bent and the other end is straight, and the sheet metal part 902 is in contact with the straight end of the bend pipe part 901, and the sheet metal part 902 is in a sheet shape and is perpendicular to the straight end of the bend pipe part 901

[0043] The first positioning component includes a middle limiting block 4 and a tail limiting block 5, both of which are fixedly connected to the base 1; a first limiting groove 401 is formed at the top of the middle limiting block 4 for placing the middle part of the bent pipe part 901, and a second limiting groove 501 is formed on one side of the tail limiting block 5 close to the middle limiting block 4 for placing the bent part of the bent pipe part 901.

[0044] The bent pipe part 901 is placed in the first positioning component, with its middle part located in the first limiting groove 401 and the bent part located in the second limiting groove 501, thereby limiting the translational degrees of freedom of the bent pipe part 901 in the X, Y, and Z axis directions, as well as the rotational degrees of freedom around the Y and Z axis directions; the length direction of the second limiting groove 501 is perpendicular to the base 1, and the side wall of the second limiting groove 501 can be used to limit the rotation of the bent part around the X axis direction, finally realizing the full-degree-of-freedom limitation of the bent pipe part 901.

[0045] In order to ensure the straightness of the bent pipe part 901 relative to the sheet metal part 902, an adjusting component is also provided on the first positioning component.

[0046] The adjusting component includes a second positioning screw 402 and a third positioning screw 502 parallel to the Y-axis direction. The second positioning screw 402 is screwed through the upper part of the middle limiting block 4, and one end of the second positioning screw 402 extends into the first limiting groove 401; the third positioning screw 502 is screwed through the upper part of the tail limiting block 5, and one end of the third positioning screw 502 extends into the second limiting groove 501.

[0047] By rotating the second positioning screw 402 and the third positioning screw 502, their ends can move along their respective axes, and the ends are in contact with the bent pipe part 901, so as to adjust the overall or local movement of the bent pipe part 901 along the Y-axis direction, thereby ensuring the straightness of the bent pipe part 901 relative to the sheet metal part 902.

[0048] Further, in order to better adjust the middle position of the bent pipe part 901, there are two middle limiting blocks 4, and the two middle limiting blocks 4 and the tail limiting block 5 are linearly distributed along the X-axis direction together.

[0049] The second positioning component includes an end limiting block 2 and a side limiting block 3 connected to the base 1. The sides of the two close to the sheet metal part (i.e., the sheet metal part 902) are perpendicular to each other, and a first positioning screw 202 is screwed through the end limiting block 2 along the X-axis direction.

[0050] By rotating the first positioning screw 202, its end can move along its own axis; during clamping, the end of the sheet metal part 902 abuts against the side limiting block 3 to limit its translational freedom in the Y-axis direction; one side of the sheet metal part 902 is in contact with the straight end of the bent pipe part 901, and the other side is in contact with the end of the first positioning screw 202, limiting its translational freedom in the X-axis direction; since the sheet metal part 902 is placed on the base 1, its freedom in the Z-axis direction is also limited. At the same time, the rotational freedom of the sheet metal part 902 is also limited.

[0051] To ensure the concentricity of the bent pipe part 901 relative to the sheet metal part 902, a cushion block 8 is provided on the side of the end limiting block 2 close to the second positioning component to support the sheet metal part 902, so that the height center of the sheet metal part 902 corresponds to the axis of the bent pipe part 901, and the cushion block 8 is fixedly connected to the base 1.

[0052] The pressing component includes a quick clamp 6. The quick clamp 6 adopts the prior art and can use the operating handle to realize the clamping and loosening functions of the clamp, such as telescopic shaft type clamps and telescopic block type clamps, etc.; the function of the quick clamp 6 here is to firmly fix the positioned bent pipe part 901 and sheet metal part 902 on the base 1, facilitating subsequent welding work.

[0053] To ensure the working height of the quick clamp 6, supports 7 are provided on one side of the first positioning component and the second positioning component to support the quick clamp 6; that is, the bottom of the quick clamp 6 is fixedly connected to the base 1 through the support 7, and the working end at the upper part extends above the first positioning component and the second component to press the product 9 therein.

[0054] Here, three quick clamps 6 are used, corresponding to the two middle limiting blocks 4 and the sheet metal part 902 respectively.

[0055] Working principle:

[0056] First, place the bent pipe part 901 of the product 9 in the first positioning component, so that the middle part of the bent pipe part 901 is located in the first limiting groove 401 and the bending part is located in the second limiting groove 501. Then rotate the second positioning screw 402 and the third positioning screw 502 to adjust the straightness of the bent pipe part 901; then place the sheet metal part 902 in the second positioning component, so that the end of the sheet metal part 902 is in contact with the side limiting block 3, and both sides are in contact with the straight end of the bent pipe part 901 and the end of the first positioning screw 202 respectively. Under the action of the cushion block 8, ensure the concentricity between the two; finally, press the product 9 tightly therein through the pressing component to facilitate subsequent welding work.
