Abstract
Description
Technical Field
[0001] This application relates to the field of tooling technology, and in particular to a tooling for processing vulnerable welding parts of a wind tunnel. Background Technology
[0002] Welding is a crucial step in the manufacturing process of wind turbines. Traditional manual welding methods suffer from inconsistent weld quality, low efficiency, and a tendency to deform during the welding process. With the continuous development of wind turbine technology, the requirements for welding quality and efficiency are becoming increasingly stringent; therefore, the importance of automated equipment in the manufacturing industry is self-evident.
[0003] In automated welding operations of wind turbine ducts, the gasket plays a crucial role in weld quality because it comes into direct contact with the duct. However, to ensure the duct's appearance is free of scratches, the gasket must be made of copper, a component with relatively low hardness. But copper has relatively poor durability, so equipment is often manufactured with the gasket as an insert for easy disassembly and maintenance. However, temporary gaskets have complex shapes, are difficult to clamp, and require frequent maintenance. Utility Model Content
[0004] Therefore, it is necessary to provide a machining fixture for easily damaged welding parts of the wind turbine duct, addressing the problem that copper gaskets used in the automatic welding operation of traditional wind turbine ducts are not easy to clamp and maintain.
[0005] This application provides a machining fixture for easily damaged welding parts of a wind tunnel, including:
[0006] The blank is designed as a long plate.
[0007] A tooling assembly is disposed at the bottom of the blank, and the blank is fixedly connected to the tooling assembly;
[0008] The tooling assembly is characterized in that it comprises:
[0009] A tooling shaft is disposed at the bottom of the blank. The tooling shaft is cylindrical and has a first positioning groove at its top. The bottom of the blank is inserted into the first positioning groove.
[0010] A first positioning block is disposed on the tooling shaft, and the first positioning block is fixedly connected to the tooling shaft by a first bolt.
[0011] The second positioning block is disposed on the tooling shaft, and the second positioning block is fixedly connected to the tooling shaft by the second bolt.
[0012] The blank is disposed between the first positioning block and the second positioning block, with the first positioning block inserted into one end of the blank and the second positioning block inserted into the other end of the blank.
[0013] This application relates to a machining fixture for easily damaged welding parts of a wind tunnel. The fixture first places a blank in a first positioning groove at the top of the fixture shaft, then inserts a first positioning block into one end of the blank, and then uses a first bolt to fix the first positioning block to the fixture shaft. The other end of the first positioning block is then fixed to the blank, and a second bolt is used to fix a second positioning block to the fixture shaft. This fixes the blank at the top of the fixture shaft, thus facilitating the machining of the blank. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0029] like Figures 1 to 2 As shown, in one embodiment of this application, it includes a blank 11 and a tooling assembly 12.
[0030] The blank 11 is configured as a long plate.
[0031] The tooling assembly 12 is disposed at the bottom of the blank 11, and the blank 11 is fixedly connected to the tooling assembly 12.
[0032] The tooling assembly 12 is characterized in that it includes a tooling shaft 121, a first positioning block 122, and a second positioning block 123.
[0033] The tooling shaft 121 is disposed at the bottom of the blank 11. The tooling shaft 121 is cylindrical. A first positioning groove 13 is formed at the top of the tooling shaft 121. The bottom of the blank 11 is inserted into the first positioning groove 13.
[0034] The first positioning block 122 is disposed on the tooling shaft 121. The first positioning block 122 is fixedly connected to the tooling shaft 121 by a first bolt 15.
[0035] The second positioning block 123 is disposed on the tooling shaft 121. The second positioning block 123 is fixedly connected to the tooling shaft 121 by the second bolt 16.
[0036] The blank 11 is disposed between the first positioning block 122 and the second positioning block 123. The first positioning block 122 is inserted into one end of the blank 11. The second positioning block 123 is inserted into the other end of the blank 11.
[0037] Specifically, the structure of the first positioning block 122 is the same as that of the second positioning block 123. The first positioning block 122 has a first through hole in the middle, through which the first bolt 15 passes. A first protrusion is fixed on the first positioning block 122 and inserted into one end of the blank 11. The second positioning block 123 has a second through hole in the middle, through which the second bolt 16 passes. A second protrusion is fixed on the second positioning block 123 and inserted into the other end of the blank 11.
[0038] In this embodiment, the blank 11 is first placed in the first positioning groove 13 at the top of the tooling shaft 121, then the first positioning block 122 is inserted into one end of the blank 11, and then the first positioning block 122 is fixed on the tooling shaft 121 using the first bolt 15. The other end of the first positioning block 122 is then fixed, and the second positioning block 123 is fixed on the tooling shaft 121 using the second bolt 16. Thus, the blank 11 is fixed on the top of the tooling shaft 121 so that the position of the blank 11 is fixed, which facilitates the processing of the blank 11.
[0039] like Figure 3 As shown, in one embodiment of this application, the first positioning groove 13 includes a stop groove 131 and a plurality of clearance grooves 132.
[0040] The stop groove 131 is formed on the top of the tooling shaft 121. The stop groove 131 is provided along the length extension direction of the tooling shaft 121.
[0041] Multiple clearance grooves 132 are provided. All clearance grooves 132 are formed on the top of the tooling shaft 121. Multiple clearance grooves 132 are provided on both sides of the length extension direction of the stop groove 131. The multiple clearance grooves 132 are equidistantly arranged along the length extension direction of the stop groove 131.
[0042] Specifically, the first positioning groove 13 includes a stop groove 131 and a plurality of contact protrusions. The plurality of contact protrusions are all disposed in the first positioning groove 13 and are evenly distributed on the two side walls of the first positioning groove 13.
[0043] In this embodiment, by opening multiple clearance grooves 132 on the side wall of the first positioning groove 13, multiple bosses are formed, which further reduces the contact surface between the assembly and the blank 11 to ensure assembly accuracy and solve the problem of difficult assembly operation of the blank 11.
[0044] like Figure 3 As shown, in one embodiment of this application, each of the relief grooves 132 is connected to the stop groove 131.
[0045] like Figures 3 to 5As shown, in one embodiment of this application, a first central hole 121a is provided at one end of the tooling shaft 121. The first central hole 121a is located near the first positioning block 122. The axis of the first central hole 121a is collinear with the axis of the tooling shaft 121.
[0046] A second center hole 121b is provided at the other end of the tooling shaft 121. The second center hole 121b is located near the second positioning block 123. The axis of the second center hole 121b is collinear with the axis of the tooling shaft 121.
[0047] Specifically, the diameter of the first central hole 121a may be equal to or different from the diameter of the second central hole 121b.
[0048] In this embodiment, the first center hole 121a and the second center hole 121b are provided for aligning the arc center when machining the arc surface of the blank 11.
[0049] like Figures 4 to 5 As shown, in one embodiment of this application, a second positioning groove 14 is provided at the bottom of the tooling shaft 121.
[0050] Specifically, the bottom wall of the second positioning groove 14 is set parallel to the bottom wall of the first positioning groove 13.
[0051] In this embodiment, the ground of the second positioning groove 14 is used for secondary alignment of the semi-finished blank 11.
[0052] like Figures 3 to 6 As shown, in one embodiment of this application, the tooling shaft 121 has a plurality of disassembly through holes 121c. The disassembly through holes 121c are disposed between the first positioning groove 13 and the second positioning groove 14. The plurality of disassembly through holes 121c are equidistantly arranged along the length extension direction of the tooling shaft 121. The top of each disassembly through hole 121c communicates with the first positioning groove 13. The bottom of each disassembly through hole 121c communicates with the second positioning groove 14.
[0053] In this embodiment, multiple disassembly through holes 121c are provided to prevent the blank 11 from being too close to the bottom wall when it is assembled into the first positioning groove 13 and the second positioning groove 14, which could easily form a closed cavity or generate a large adsorption force that would make it difficult to disassemble the blank 11 during the processing.
[0054] Furthermore, if the blank 11 is fitted too tightly into the first positioning groove 13 and the second positioning groove 14, making it inconvenient to remove the blank 11, the blank 11 can be pushed out by inserting bolts or other rods into the disassembly through hole 121c.
[0055] like Figure 5 As shown, in one embodiment of this application, the tooling shaft 121 has a first threaded bottom hole 19 and a second threaded bottom hole 20. Both the first threaded bottom hole 19 and the second threaded bottom hole 20 are located at the top of the tooling shaft 121. The first threaded bottom hole 19 is located near the first positioning block 122. The first bolt 15 is threadedly connected to the first threaded bottom hole 19.
[0056] The second threaded hole 20 is located near the second positioning block 123. The second bolt 16 is threadedly connected to the second threaded hole 20.
[0057] The tooling shaft 121 has a first locating pin hole 21 and a second locating pin hole 22. The first locating pin hole 21 is located on one side of the first threaded bottom hole 19. The second locating pin hole 22 is located on one side of the second threaded bottom hole 20.
[0058] In this embodiment, the first bolt 15 passes through the first positioning block 122 and is inserted into the first threaded bottom hole 19, thereby locking the position of the first positioning block 122. Then, by passing a positioning pin through the first positioning block 122 and inserting it into the first positioning pin hole 21, the rotation of the first positioning block 122 is limited, so that the position of the first positioning block 122 is stable and secure. The second bolt 16 passes through the second positioning block 123 and is inserted into the second threaded bottom hole 20, thereby locking the position of the second positioning block 123. Then, by passing a positioning pin through the second positioning block 123 and inserting it into the second positioning pin hole 22, the rotation of the second positioning block 123 is limited, so that the position of the second positioning block 123 is stable and secure.
[0059] like Figure 5 As shown, in one embodiment of this application, the bottom of the tooling shaft 121 is provided with a third threaded bottom hole 23 and a fourth threaded bottom hole 24. The third threaded bottom hole 23 is located near the first positioning block 122. The third bolt 17 is threadedly connected to the third threaded bottom hole 23.
[0060] The fourth threaded bottom hole 24 is located near the second positioning block 123. The fourth bolt 18 is threadedly connected to the fourth threaded bottom hole 24.
[0061] In this embodiment, the first bolt 15 is first rotated to disengage from the first threaded hole 19, at which point the first positioning block 122 is removed. The second bolt 16 is then rotated to disengage from the second threaded hole 20, at which point the second positioning block 123 is removed. The blank 11 is then assembled into the second positioning groove 14. Next, the first positioning block 122 is locked in position by connecting the third bolt 17 to the third threaded hole 23, and the first positioning block 122 abuts against one end of the blank 11. The second positioning block 123 is locked in position by connecting the fourth bolt 18 to the fourth threaded hole 24, and the second positioning block 123 abuts against the other end of the blank 11, thereby positioning the blank 11 in the second positioning groove 14.
[0062] The technical features of the above embodiments can be combined arbitrarily, and the execution order of the method steps is not restricted. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0063] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
