Description

Technical Field

[0001] This utility model belongs to the field of welding tooling technology, and in particular relates to a welding positioning device for the frame of a precision semiconductor testing equipment. Background Technology

[0002] In the manufacturing process of pipe fitting frames, plates are typically welded onto the pipes to form the frame structure. Traditional methods mostly involve manually supporting the plates and pipes or using simple clamps to fix them. This method not only makes it difficult to ensure the flatness between the pipes, but also requires multiple and repeated use of various positioning and measuring tools to accurately position the plates and pipes, making the operation cumbersome, time-consuming, and labor-intensive. Furthermore, operators are highly prone to incomplete welds during the welding process. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a precision semiconductor testing equipment tube frame welding positioning device, which can quickly and accurately position the vertical tubes, horizontal tubes and plates, improve work efficiency and reduce missed welding.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a welding and positioning device for a pipe frame of a precision semiconductor testing equipment, wherein the pipe frame includes a vertical pipe and a horizontal pipe that can surround and form a rectangular frame, and plates are provided on the vertical pipe and the horizontal pipe; the positioning device includes a horizontal worktable, a frame assembly assembly and a plate assembly assembly arranged sequentially on the horizontal worktable.

[0005] The frame assembly includes several first limiting blocks disposed on the horizontal workbench, and the several first limiting blocks can abut against the inner and outer sides of the rectangular frame.

[0006] The plate assembly includes a raised base plate disposed on the horizontal workbench. The raised base plate is provided with a plurality of second limiting blocks for limiting the rectangular frame and a third limiting block and positioning post for limiting the plate.

[0007] Optionally, the horizontal workbench is equipped with quick clamps that can abut against or press down on the rectangular frame and the plate.

[0008] Optionally, the horizontal worktable is provided with a plurality of mounting holes arranged in a linear array, and the first limiting block and the heightening base plate can be mounted at any position on the horizontal worktable through the mounting holes.

[0009] Optionally, several of the first limiting blocks can be attached to the rectangular frame in at least two mutually perpendicular directions on the same horizontal plane.

[0010] Optionally, several of the third limiting blocks and the positioning posts can be attached to the plate in at least two mutually perpendicular directions on the same horizontal plane.

[0011] Optionally, a through hole is provided on one side of the first limiting block that abuts against the horizontal worktable, and the length of the through hole is greater than the straight-line distance between any two adjacent mounting holes on the horizontal worktable.

[0012] Optionally, the thickness of the heightening base plate is greater than the thickness of the plate.

[0013] Optionally, the number of the panel assembly components is two.

[0014] Compared with existing technologies, the beneficial effects achieved by this utility model are as follows: The positioning device in this technical solution eliminates the need for repeated measurements by operators. Through a first limiting block on the horizontal workbench and second and third limiting blocks and positioning posts on the raised base plate, the welding positions between vertical pipes, horizontal pipes, and plates can be accurately positioned. Furthermore, using this positioning device allows for the assembly and welding of the rectangular frame first, followed by the assembly and welding of the rectangular frame and plates, facilitating division of labor and improving efficiency. It also effectively prevents incomplete welding. Attached Figure Description

These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0020] It should be noted that if directional indicators (such as up, down, bottom, top, etc.) are involved in this embodiment, these directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances. Example 1

[0021] like Figures 1-2 As shown, a precision semiconductor testing equipment pipe frame welding and positioning device is disclosed. The pipe frame includes a vertical pipe 101 and a horizontal pipe 102 that can surround and form a rectangular frame 1. Plates 2 are disposed on the vertical pipe 101 and the horizontal pipe 102. The positioning device includes a horizontal worktable 3, a frame assembly assembly assembly, and a plate assembly assembly assembly arranged sequentially on the horizontal worktable 3. The frame assembly assembly assembly is used to position the vertical pipe 101 and the horizontal pipe 102 when assembling the rectangular frame 1. The plate assembly assembly assembly is used to position the welded rectangular frame 1 and can also position the plate 2 on the rectangular frame 1.

[0022] Specifically, the frame assembly includes several first limiting blocks 4 set on the horizontal workbench 3. These first limiting blocks 4 can abut against the inner and outer sides of the rectangular frame 1, such as... Figure 1 As shown, the first limiting block 4 can position the assembly position of the vertical tube 101 and the horizontal tube 102, ensuring the dimensional accuracy of the rectangular frame 1 assembly.

[0023] Specifically, the sheet metal assembly includes a raised base plate 5 mounted on a horizontal workbench 3. The rectangular frame 1 is suspended on the raised base plate 5, facilitating rapid heat dissipation during welding. And when... Figure 1As shown, when plates 2 need to be welded to both sides of the rectangular frame 1, the thickness of the raised base plate 5 is greater than the thickness of the plates 2 to reserve space for placing the plates 2. Furthermore, the raised base plate 5 is provided with several second limiting blocks 6 for limiting the rectangular frame 1, and third limiting blocks 7 and positioning posts 8 for limiting the plates 2. The second limiting blocks 6 can position the rectangular frame 1 on the raised base plate 5, ensuring the uniqueness of the position of the rectangular frame 1 relative to the raised base plate 5. Similarly, the third limiting blocks 7 and positioning posts 8 can ensure the uniqueness of the position of the plates 2 relative to the raised base plate 5, thereby ensuring the uniqueness of the welding position between the rectangular frame 1 and the plates 2.

[0024] In this technical solution, the vertical pipe 101 and the horizontal pipe 102 are placed sequentially on the horizontal workbench 3. The first limiting block 4 can form the outer contour of the rectangular frame 1 on the horizontal workbench 3. That is, the position of the vertical pipe 101 and the horizontal pipe 102 can be accurately positioned by the frame assembly assembly, so that the operator can fix the relative position between the vertical pipe 101 and the horizontal pipe 102 by welding. The rectangular frame 1, which is assembled and welded by the frame assembly assembly, can be placed on the plate assembly assembly. The second limiting block 6 and the positioning post 8 on the plate assembly assembly can accurately position the rectangular frame 1 and the plate 2, so that the operator can weld the rectangular frame 1 and the plate 2. The positioning device in this technical solution can accurately locate the welding position between the vertical pipe 101, the horizontal pipe 102 and the plate 2 without the operator having to measure repeatedly. At the same time, the welding mode of welding the rectangular frame 1 first and then welding the rectangular frame 1 and the plate 2 is adopted, which facilitates the division of labor among operators, improves efficiency, and effectively avoids the occurrence of missed welds.

[0025] Furthermore, such as Figure 1 As shown, to further improve the welding accuracy between the vertical pipe 101 and the horizontal pipe 102, and between the rectangular frame 1 and the plate 2, a quick clamp 9 is provided on the horizontal worktable 3, which can abut or press against the rectangular frame 1 and the plate 2. The quick clamp 9 is existing technology, and the number and position of the quick clamp 9 in this technical solution can be adjusted according to actual needs. The quick clamp 9 is easy to operate and stable, and can effectively fix the position of the vertical pipe 101 and the horizontal pipe 102 on the horizontal worktable 3, and the position of the plate 2 on the rectangular frame 1.

[0026] Furthermore, such as Figure 1As shown, the horizontal worktable 3 has several mounting holes 301 arranged in a linear array. The first limiting block 4 and the raising base plate 5 can be positioned at any position on the horizontal worktable 3 through the mounting holes 301. Specifically, bolts or other fasteners can be inserted into the first limiting block 4 and the raising base plate 5. The bolts or other fasteners can pass through the mounting holes 301 and can be fixed to the horizontal worktable 3 with nuts. In this technical solution, the positions of the first limiting block 4 and the raising base plate 5 on the horizontal worktable 3 can be adjusted according to actual needs, ensuring positioning accuracy while also improving the versatility of the positioning device to meet the positioning requirements of pipe fitting frames of different specifications.

[0027] The above, such as Figure 1 As shown, a through hole 401 is provided on the side of the first limiting block 4 that abuts against the horizontal worktable 3. The length of the through hole 401 is greater than the straight-line distance between any two adjacent mounting holes 301 on the horizontal worktable 3. Bolts can pass through the through hole 401 on the first limiting block 4. When the bolt and nut are not fully tightened, the position of the first limiting block 4 on the horizontal worktable 3 can be finely adjusted according to the positioning requirements of the vertical tube 101 and the horizontal tube 102 to further improve the positioning accuracy.

[0028] In this embodiment, to ensure the stability of the first limiting block 4, the second limiting block 6, the third limiting block 7, and the positioning post 8 when positioning the rectangular frame 1 and the plate 2, several first limiting blocks 4 can be attached to the rectangular frame 1 in at least two mutually perpendicular directions on the same horizontal plane. Several third limiting blocks 7 and positioning posts 8 can be attached to the plate 2 in at least two mutually perpendicular directions on the same horizontal plane. Example 2

[0029] like Figure 1 As shown, based on Embodiment 1, the number of plate assembly components is two, namely, the rectangular frame 1 that has completed the initial welding can be placed on one plate assembly component with the front facing up, and can be placed on the other plate assembly component with the back facing up, so as to further subdivide the welding process of the pipe frame and improve work efficiency.

[0030] Working principle: The vertical tube 101 and horizontal tube 102 are placed sequentially on the horizontal workbench 3. The first limiting block 4 can form the outer contour of the rectangular frame 1 on the horizontal workbench 3, that is, the position of the vertical tube 101 and horizontal tube 102 can be accurately positioned by the first limiting block 4, so that the operator can fix the position of the vertical tube 101 and horizontal tube 102 by using the quick clamp 9, and then weld and fix the vertical tube 101 and horizontal tube 102. Then the rectangular frame 1 can be placed on the raising base plate 5. The second limiting block 6 and positioning post 8 on the plate assembly can accurately position the rectangular frame 1 and plate 2. After fixing the position of the rectangular frame 1 and plate 2 by using the quick clamp 9, the operator can accurately weld and fix the rectangular frame 1 and plate 2. The positioning device in this technical solution can accurately locate the welding position between the vertical tube 101, horizontal tube 102 and plate 2 without the operator having to measure repeatedly. Meanwhile, the welding mode of first welding the rectangular frame 1 and then welding the rectangular frame 1 to the plate 2 is adopted, which facilitates the division of labor and cooperation among operators, improves efficiency, and can also effectively avoid the occurrence of missed welds.

[0031] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
