[0029] 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.

[0030] As Figures 1-6 shown, a semiconductor precision pipe fitting flange welding positioning device includes a bottom plate 1, a top plate 2 and a connecting column 3. The two ends of the connecting column 3 are respectively connected to the bottom plate 1 and the top plate 2, and the connecting column 3 is perpendicular to the bottom plate 1 and the top plate 2; the double-flange tubular workpiece includes a first flange 41, a second flange 42 and a tubular sub-component 43. The first flange 41 and the second flange 42 are oppositely arranged at both ends of the tubular sub-component 43, and the distance between the opposite side surfaces of the bottom plate 1 and the top plate 2 is equal to the height of the double-flange tubular workpiece.

[0031] During use, the first flange 41 is fixedly installed on the bottom plate 1, the second flange 42 is fixedly installed on the top plate 2, and then the connecting column 3 is passed through the inside of the tubular sub-component 43 so that its two ends are respectively connected to the bottom plate 1 and the top plate 2. At this time, the components to be welded of the double-flange tubular workpiece are temporarily assembled together, providing a more accurate and stable positional relationship for subsequent workpiece welding, ensuring the quality and stability of workpiece welding, being able to resist greater welding deformation stress during the welding process, and also improving the durability.

[0032] A flange is a mechanical part used to connect devices such as pipes, valves, and pumps. For ease of assembly, reserve holes, also known as bolt holes, are usually provided at its edge. By inserting bolts, two flanges can be tightly connected together, thus achieving the connection and sealing between pipes or devices.

[0033] To facilitate the quick and fixed installation of the first flange 41 and the second flange 42 on the corresponding bottom plate 1 and top plate 2 respectively, first connection holes 13 and second connection holes 23 are respectively provided on the bottom plate 1 and the top plate 2. The number and position of the first connection holes 13 and the second connection holes 23 correspond to the reserve holes of the corresponding flanges, and the two are fixedly connected by fasteners passing through the connection holes and the reserve holes.

[0034] The bottom plate 1 and the first flange 41 are connected by a first fastener 6, and the top plate 2 and the second flange 42 are connected by a second fastener 7. Both the first fastener 6 and the second fastener 7 are screws, and the first connection holes 13 and the second connection holes 23 are threaded holes.

[0035] Taking the installation of the first fastener 6 as an example, place the first flange 41 on the bottom plate 1 so that the reserve hole aligns with the first connection hole 13, and then screw one end of the first fastener 6 through the reserve hole into the first connection hole 13 to complete the fixed installation of the first flange 41 on the bottom plate 1.

[0036] Furthermore, a fitting positioning block 5 is fixedly installed on the bottom plate 1, and the fitting positioning block 5 is located inside the first flange 41; the fitting positioning block 5 is fixedly installed on the bottom plate 1 by screws, and its function is to provide a positioning function for the fitting, making the assembly and welding of the workpiece faster and more convenient.

[0037] To achieve the quick disassembly and assembly function of the device, the connecting column 3 is connected to the bottom plate 1 and the top plate 2 by a detachable plug-in connection method.

[0038] The connecting column 3 includes a column body 31, a first joint 32, and a second joint 33. The first joint 32 and the second joint 33 are respectively arranged at both ends of the column body 31. The first joint 32 and the second joint 33 protrude from the end face of the column body 31, and the column body 31 is respectively plugged into the bottom plate 1 and the top plate 2 through the first joint 32 and the second joint 33.

[0039] Specifically, first jacks 11 and second jacks 21 are respectively provided on the bottom plate 1 and the top plate 2. The first joint 32 and the second joint 33 are respectively fitted and embedded into the first jack 11 and the second jack 21; at this time, the length of the column body 31 is equal to the height of the double-flange tubular workpiece.

[0040] Furthermore, the first joint 32 and the second joint 33 are staggeredly distributed at both ends of the column 31, which can make the force between the connecting column 3, the bottom plate 1 and the top plate 2 more reasonable and stable; the first joint 32 and the second joint 33 are integrally formed with the column 31, and the cross-section of the joint is smaller than that of the column 31, so as to form a boss on one side of the joint to achieve installation positioning.

[0041] In addition, in order to further ensure the connection strength between the connecting column 3 and the bottom plate 1 and the top plate 2, mounting holes 34 are provided on one side of the first joint 32 and the second joint 33. The mounting holes 34 are provided on the column 31 and are parallel to the length direction of the column 31; first through holes 12 and second through holes 22 are respectively provided on one side of the first jack 11 and the second jack 21. The first through hole 12 and the second through hole 22 correspond to the corresponding mounting holes 34 respectively, so as to facilitate the insertion of the third fastener 8 and the fourth fastener 9. That is, the connecting column 3 is fixedly connected to the bottom plate 1 through the third fastener 8 and is fixedly connected to the top plate 2 through the fourth fastener 9. The third fastener 8 and the fourth fastener 9 are screws, and the mounting holes 34 are corresponding threaded holes.

[0042] Working principle:

[0043] First, the first flange 41 is fixedly installed on the bottom plate 1, the second flange 42 is fixedly installed on the top plate 2, then one end of the connecting column 3 is fixed on the bottom plate 1, then the tubular sub-component 43 is aligned with the first flange 41 and sleeved on the outside of the connecting column 3, and finally the top plate 2 with the second flange 42 installed is connected to the other end of the connecting column 3. At this time, the components to be welded of the double-flange tubular workpiece are temporarily assembled together, which can ensure the relative relationship accuracy of the double-flange in the case of spacing one tubular workpiece, and can well control the welding deformation. The position control method of this device can be applied to a variety of similar workpieces to control the position accuracy.

[0044] In summary, the semiconductor precision pipe fitting flange welding positioning device proposed by the present utility model can reduce the welding labor cost and the operation difficulty of welding personnel, improve the safety of welding operation, and make the welding effect more stable.
