Abstract
Description
Technical Field
[0001] This application relates to the technical field of machining equipment, and in particular to a nut welding fixture. Background Technology
[0002] During the production of sheet metal, because the sheet metal itself is thin, it is impossible to drill holes or tap it. Therefore, nuts are welded onto the sheet metal. Thus, welding nuts to sheet metal is a common and important process.
[0003] like Figure 1 As shown, the plate 5 has several through holes drilled in it. A nut 6 needs to be welded to the opening of each through hole, and the centerline of the nut 6 needs to be aligned with the centerline of the through hole. The operator needs to tighten the nut onto the plate by hand or with simple tools. The nut is prone to moving during the welding process, resulting in inaccurate welding position, which needs to be improved. Utility Model Content
[0004] The purpose of this application is to provide a nut welding fixture for accurately welding nuts to the appropriate positions.
[0005] The nut welding fixture provided in this application adopts the following technical solution: it includes an operating table, the operating table is provided with a first positioning block, and a second positioning block is provided on the side of the first positioning block away from the operating table. The radius of the second positioning block is smaller than the radius of the first positioning block. The first positioning block is used to cooperate with the through hole of the plate, and the second positioning block is used to cooperate with the nut. The operating table is connected to a clamping assembly, and the clamping assembly is used to clamp the plate and the nut.
[0006] By adopting the above technical solution, the first positioning block engages with the through hole of the plate to initially position the plate and prevent it from shifting during welding. The second positioning block engages with the nut, and the radius of the second positioning block is smaller than that of the first positioning block, which ensures that the nut is accurately aligned with the axis of the through hole and prevents the nut from moving before welding. The clamping assembly further clamps the plate and the nut, thereby effectively improving the accuracy of the nut welding position and ensuring welding quality.
[0007] Optionally, the clamping assembly includes a carrier plate slidably connected to the operating table, a first driving member for driving the carrier plate to slide closer to or further away from the operating table, and a clamping column connected to the side of the carrier plate closer to the operating table, wherein the first driving member is connected to the operating table.
[0008] By adopting the technical scheme, the carrier plate is slidably connected to the operation table, and the first driving member is used to realize accurate movement of the carrier plate, so as to adjust the position of the pressing column and ensure accurate pressing of the plate and the nut. The pressing column is connected to one side of the carrier plate close to the operation table, directly acts on the plate and the nut, and provides stable pressing force, thereby avoiding displacement of the nut during welding and improving welding precision and quality.
[0009] Optionally, the radius size of the end of the pressing column away from the carrier plate gradually decreases in the direction away from the carrier plate, and the axis of the pressing column is the same as the axis of the first positioning block.
[0010] By adopting the technical scheme, the end of the pressing column is clamped into the nut and abuts against the inner wall of the nut, so that the nut is more accurately moved to the corresponding position, and displacement of the nut during pressing is avoided, thereby improving positioning precision and stability of the nut during welding.
[0011] Optionally, a plurality of first positioning blocks are arranged on the operation table, a plurality of pressing columns are connected to the carrier plate, the number of the second positioning blocks, the number of the first positioning blocks and the number of the pressing columns are equal, the second positioning blocks correspond to the first positioning blocks one by one, and the pressing columns correspond to the second positioning blocks one by one.
[0012] By adopting the technical scheme, a plurality of pressing columns can simultaneously press a plurality of nuts, which facilitates an operator to weld a plurality of nuts at a time and improves the efficiency of overall welding of the nuts.
[0013] Optionally, the operation table is slidably connected with a jacking column, the jacking column is slidably connected with the operation table, the first positioning block is arranged at one end of the jacking column close to the carrier plate, the first positioning block is located between the jacking column and the second positioning block, and the operation table is connected with a driving assembly for driving the jacking column to slide towards or away from the carrier plate.
[0014] By adopting the technical scheme, when the nut welding is completed, the driving assembly drives the jacking column to slide towards the carrier plate, the jacking column abuts against the plate and drives the plate to slide towards the carrier plate, so that the plate is separated from the operation table, and the operator can easily take the plate.
[0015] Optionally, the driving assembly comprises a support plate slidably connected to the operation table and a second driving member for driving the support plate to slide towards or away from the carrier plate, the second driving member is connected to the support plate, and each jacking column is connected to the support plate.
[0016] By adopting the technical scheme, one second driving member and one support plate can drive a plurality of jacking columns to move synchronously, thereby reducing the number of workpieces and improving work efficiency.
[0017] Optionally, the operating platform is connected with a guide column, and the guide column is in sliding fit with the support plate.
[0018] By adopting the above technical scheme, when the support plate slides, the guide column is in sliding fit with the support plate, which plays a guiding and limiting role on the sliding of the support plate, thereby improving the stability of the jacking column sliding, i.e., improving the effect of jacking the plate.
[0019] Optionally, the support plate is connected with a first sleeve, the first sleeve is connected with the support plate through a locking piece, and the first sleeve is provided with a guide hole for sliding fit with the guide column.
[0020] By adopting the above technical scheme, different first sleeves are replaced through the locking piece, thereby adapting to guide columns of different radius sizes.
[0021] Optionally, the support plate is provided with a hollow hole.
[0022] By adopting the above technical scheme, the hollow hole can reduce the overall weight of the support plate, thereby reducing the load of the driving assembly when driving the support plate to slide, improving the driving efficiency and reducing the energy consumption. In addition, the design of the hollow hole also helps to reduce the amount of material used and reduce the production cost.
[0023] Optionally, the carrier plate is provided with a positioning groove for clamping the pressing column, and the pressing column is connected with the carrier plate through a fixing piece.
[0024] By adopting the above technical scheme, the positioning groove can preliminarily position the pressing column, avoid the pressing column from deviating during installation, and ensure the accurate alignment of the pressing column with the plate and the nut. At the same time, the pressing column is connected with the carrier plate through the fixing piece, so that the installation of the pressing column is more stable, effectively preventing the pressing column from loosening or falling off due to external force during welding, thereby improving the precision and stability of the nut welding. When the pressing column is damaged, it is also convenient to replace.
[0025] In summary, the present application has the following at least one beneficial technical effect:
[0026] 1. The first positioning block is in fit with the through hole of the plate, which can preliminarily position the plate to prevent the plate from deviating during welding; the second positioning block is in fit with the nut, and the radius size of the second positioning block is smaller than that of the first positioning block, which can ensure that the nut is accurately aligned with the axis of the through hole, avoiding the nut from moving before welding; the pressing assembly further presses the plate and the nut, thereby effectively improving the accuracy of the nut welding position and ensuring the welding quality.
[0027] 2. The end of the clamping column is inserted into the nut and abuts against the inner wall of the nut, so that the nut can move more accurately to the corresponding position and avoid displacement when the nut is clamped, thereby improving the positioning accuracy and stability of the nut welding.

[0038] The following is in conjunction with the appendix Figure 2 - Appendix Figure 9 This application will be described in further detail.
[0039] This application discloses a nut welding fixture.
[0040] Combination Figure 2 , Figure 3and Figure 4 As shown, the system includes an operating table 1, with two sets of clamping assemblies 2 connected to each other. Each clamping assembly 2 includes a carrier plate 21 slidably connected to the upper surface of the operating table 1, a first driving member 22 for driving the carrier plate 21 to slide towards or away from the operating table 1, and four clamping columns 23 detachably connected to the side of the carrier plate 21 near the operating table 1. The first driving member 22 is a cylinder and is fixedly connected to the upper surface of the operating table 1. The side of the carrier plate 21 near the first driving member 22 is fixedly connected to the output end of the first driving member 22. The first driving member 22 is externally connected to a controller (not shown in the figure), and the signal output end of the controller is connected to the signal input end of the first driving member 22.
[0041] Combination Figure 4 , Figure 5 and Figure 6 As shown, the side of the carrier plate 21 closest to the operating table 1 has a positioning groove 211 for the corresponding clamping column 23 to be inserted. The clamping column 23 is connected to the carrier plate 21 by a fastener 24, which is a bolt. The radius of the end of the clamping column 23 away from the carrier plate 21 gradually decreases in the direction away from the carrier plate 21.
[0042] Combination Figure 7 and Figure 8 As shown, the operating platform 1 is slidably connected to eight lifting columns 3, each corresponding to a pressing column 23. The operating platform 1 is fixedly connected to eight second sleeves 11, each corresponding to a lifting column 3, and the lifting columns 3 and second sleeves 11 are slidably engaged. Each lifting column 3 has a first positioning block 31 on the side closest to the pressing column 23, and a second positioning block 32 on the side furthest from the lifting column 3. The first positioning block 31 and the lifting column 3 are integrally formed, as are the second positioning block 32 and the first positioning block 31. The radius of the lifting column 3 is larger than the radius of the first positioning block 31, and the radius of the first positioning block 31 is larger than the radius of the second positioning block 32. The centerlines of the pressing column 23, the lifting column 3, the first positioning block 31, and the second positioning block 32 are the same. The first positioning block 31 engages with the through hole of the plate 5, and the second positioning block 32 engages with the nut 6. When the lifting column 3 is in its original state, the upper surface of the lifting column 3 is flush with the upper surface of the operating table 1.
[0043] Combination Figure 7 and Figure 8As shown, the operating platform 1 is connected to a drive assembly 4 for driving each lifting column 3 to slide towards or away from the carrier plate 21. The drive assembly 4 includes a support plate 41 slidably connected to the lower surface of the operating platform 1 and a second drive member 42 for driving the support plate 41 to slide towards or away from the carrier plate 21. The support plate 41 has a hollow hole 411. The second drive member 42 is fixedly connected to the support plate 41. The signal output terminal of the controller is connected to the signal input terminal of the second drive member 42. The output terminal of the second drive member 42 is fixedly connected to the lower surface of the operating platform 1. Each lifting column 3 is connected to the support plate 41 by bolts.
[0044] Combination Figure 8 and Figure 9 As shown, four guide posts 12 are fixedly connected to the lower surface of the operating table 1, and four first sleeves 43 are detachably connected to the support plate 41. The first sleeves 43 are connected to the support plate 41 by locking members 44, which are bolts. The first sleeves 43 are provided with guide holes 431 for sliding cooperation with the guide posts 12.
[0045] The implementation principle of a nut welding fixture according to an embodiment of this application is as follows:
[0046] The first positioning block 31 engages with the through hole of the plate 5 to initially position the plate 5, placing it in the appropriate location. The second positioning block 32 engages with the nut 6, placing the nut 6 in the appropriate location. The controller controls the first driving component 22 to open, causing the carrier plate 21 to slide closer to the operating table 1. This causes several clamping columns 23 to slide closer to the operating table 1, clamping the nut 6 and plate 5 together with the operating table 1, improving the stability of the plate 5 and nut 6. The operator welds the connection between the plate 5 and nut 6 using a welding torch. After the nut 6 is welded, the first driving component 22 drives the carrier plate 21 to slide away from the operating table 1, causing the clamping columns 23 to release the nut 6 and plate 5. The controller controls the second drive unit 42 to open, and the second drive unit 42 drives the support plate 41 to slide towards the carrier plate 21. That is, several lifting columns 3 slide towards the carrier plate 21. The lifting columns 3 abut against the plate 5 and drive the plate 5 to slide away from the operating table 1, so that the plate 5 is separated from the operating table 1, making it easier for the operator to take the plate 5 after welding.
[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
