DETAILED DESCRIPTION

[0034] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0035] Embodiment 1

[0036] Please refer to Figure 1 to Figure 2 A steel structure splicing welding production tooling fixture includes: a base 1, a trunk clamping mechanism 2 and a rib clamping mechanism 3. The base 1 is a U-shaped structure as a whole. The trunk clamping mechanism 2 is arranged on the top of the base 1. The trunk clamping mechanism 2 is used to position the steel structure trunk 5, and the rib clamping mechanism 3 is arranged in the inner middle position of the base 1. The rib clamping mechanism 3 is used to clamp and position all steel structure ribs 6, so that the steel structure trunk 5 and the steel structure ribs 6 maintain a stable standard splicing state, which is convenient for the welding mechanism to perform welding operations on them.

[0037] For details, please refer to Figure 1 , Figures 9 to 11In order to achieve the clamping and positioning of the steel structure trunk 5, the present invention designs a trunk clamping mechanism 2, and the specific scheme is as follows: the trunk clamping mechanism 2 includes an adjusting rotating member 21 and two positioning pads 22, the two positioning pads 22 are symmetrically slidably mounted on both sides of the top of the base 1, the adjusting rotating member 21 is rotatably mounted on one end of the base 1, one end of the two positioning pads 22 is respectively threadedly connected to the two ends of the adjusting rotating member, and the two ends of the adjusting rotating member 21 are provided with threads with opposite threads, which correspond to the two positioning pads 22 respectively. One side of the positioning pad 22 is provided with four linearly evenly distributed elastic support members, and the elastic support members include a contact body 23 and a support spring 24. The contact body 23 is slidably mounted on one side of the positioning pad 22, and the support spring 24 is fixed between the contact body 23 and the positioning pad 22. One side of the positioning pad 22 is provided with five slots 25, and a limit plate 26 is inserted into one of the slots 25.

[0038] It should be noted that when the above-mentioned trunk clamping mechanism 2 is in use, the position of the positioning pad 22 is first adjusted according to the length of the ribs. It is necessary to ensure that the spacing between the two positioning pads 22 is greater than the length of the steel structure rib 6, so as to facilitate the subsequent direct flipping action. During adjustment, by manually rotating the adjusting rotating piece 21, the two positioning top plates can be driven to move toward each other, so that the spacing between the two changes. After reaching the preset spacing, stop rotating the adjusting rotating piece 21, and then place the steel structure trunk 5 directly on the clamping end face of one of the positioning pads 22, so that one side of the steel structure trunk 5 is in contact with the ends of the four contact bodies 23 at the same time, and by moving the steel structure trunk 5 so that one end of it is in contact with the limit plate 26, the positioning pad 22, the limit plate 26 and the contact body Under the joint limiting action of 23, the steel structure trunk 5 is in a preset standard posture. At this time, the pre-positioning function of the steel structure trunk 5 is realized by the trunk clamping mechanism 2, wherein, by setting the elastic support member in contact with the steel structure trunk 5, in addition to the positioning effect on one side of the steel structure trunk 5, when a flipping action is required later, due to the elastic effect of the elastic support member itself, it will not hinder the flipping of the steel structure trunk 5. At this time, there is no need to separate the positioning pad 22 from the steel structure trunk 5 by rotating the adjusting rotating member 21, which is convenient for the rib clamping mechanism 3 to directly drive the steel structure to flip. In addition, a plurality of contact bodies 23 are used in combination to form point contact with the steel structure trunk 5, which is beneficial to reduce the friction resistance encountered during the flipping of the steel structure.

[0039] Please refer to Figure 3In order to realize the flipping action of the steel structure and the automatic switching function of the welding surface of the steel structure, the present invention designs a rib clamping mechanism 3, and the specific scheme is as follows: the rib clamping mechanism 3 includes a driving component 31, a placing component 32 and a clamping component 33, the driving component 31 is connected with the placing component 32 and the clamping component 33 respectively, the placing component 32 has a rotation function, which is used to position the five steel structure ribs 6 and make the five steel structure ribs 6 evenly distributed on one side of the steel structure trunk 5; the clamping component 33 is connected with the placing component 32, after the five steel structure ribs 6 are placed to the clamping end of the placing component 32, the driving component 31 is driven in the forward direction to drive the clamping component 33 to synchronously clamp and fix the five steel structure ribs 6.

[0040] For details, please refer to Figures 3 to 5 In order to meet the requirements of the flipping action of the steel structure and to effectively position all the steel structure ribs 6, the present invention improves the placement component 32 on the basis of the prior art. The specific scheme is as follows: the placement component 32 is located in the middle of the base 1, and the placement component 32 includes five placement monomers. The five placement monomers are evenly and linearly distributed along the length direction of the base 1. The number of placement monomers is convenient to five and can be adjusted according to actual use needs; the placement monomer includes a positioning seat 321 and a support column 322. The positioning seat 321 is rotatably connected to the top of the base 1, and the overall structure is U-shaped. The bottom end of the support column 322 is fixed to the inner bottom wall of the base 1.

[0041] Please refer to Figure 6 to Figure 7 In order to adapt to the above-mentioned placement component 32 and realize the synchronous clamping and fixing of all the steel structure ribs 6 on the placement component 32, the present invention designs a special clamping component 33 to be used in conjunction with the above-mentioned placement component 32. The specific scheme is as follows: the clamping component 33 includes five clamping plates 331 with the same number as the placement monomers. The five clamping plates 331 are correspondingly slidably installed on the inner bottom wall of the positioning seat 321. One side of the clamping plate 331 located on the side is fixedly connected to the end of the driving body 314, and the remaining clamping plates 331 are fixed in turn by connecting rods 332. A protective layer is provided on the clamping end surface of the clamping plate 331, and the protective layer can be made of rubber.

[0042] Please refer to Figures 7 and 8In order to match the above-mentioned placement component 32 and the clamping component 33, and realize the functions of driving the placement component 32 and the clamping component 33 respectively, the present invention designs a driving component 31, and the specific scheme is: the driving component 31 includes a mounting frame 311, a driving motor 312, a first transmission member and a second transmission member, the driving motor 312 is connected to the inner bottom wall of the base 1 through the mounting frame 311, the driving end of the driving motor 312 is connected to one end of the first transmission member, and the other end of the second transmission member is connected to the clamping component 33, one end of the second transmission member is connected to the first transmission member, and the other end is rotatably connected to the placement component 32, when the driving motor 312 rotates forward, the first transmission member drives the clamping component 33 to move, the second transmission member and the placement component 32 are in a stationary state, and when the driving motor 312 rotates reversely, the first transmission member and the second transmission member rotate together with the driving motor 312, driving the steel structure to rotate to a preset angle, and the preset angle is generally one hundred and eighty degrees. The first transmission member includes a screw rod 313 and a driving body 314, one end of the screw rod 313 is fixed to the driving end of the driving motor 312, the driving body 314 is threadedly connected to the outer side of the screw rod 313, and one end of the driving body 314 is connected to the clamping component 33; the second transmission member includes a protective shell 315, a ratchet 316, a pawl 317 and a reset spring 318, the protective shell 315 is embedded in one side of the positioning seat 321 located on the side, one end of the screw rod 313 away from the driving motor 312 is rotatably connected to the inner wall of the protective shell 315, the ratchet 316 is located in the protective shell 315 and is fixed to the rotating end of the screw rod 313, one end of the pawl 317 is rotatably connected to the inner wall of the protective shell 315, and the other end thereof is engaged with the outer side of the ratchet 316, and the reset spring 318 is fixed between the pawl 317 and the protective shell 315.

[0043] It should be noted that the use process of the above-mentioned rib clamping mechanism 3 is as follows:

[0044] After the trunk clamping mechanism 2 is used to pre-position the steel structure trunk 5, the rib clamping mechanism 3 is used to position the steel structure rib 6. The required steel structure ribs 6 are placed on the positioning seat 321 in sequence, and one end of the steel structure rib 6 is kept in close contact with one side of the steel structure body. After all the steel structure ribs 6 are installed, the steel structure rib 6 is clamped. The screw rod 313 can be driven to rotate by driving the motor 312 in the forward direction. The screw rod 313 that rotates in the forward direction will drive the ratchet 317 to rotate in the forward direction, so that it can pass through the ratchet smoothly. The claw 317 is formed, and the driving body 314 starts to move linearly along the surface of the screw rod 313 under the rotation of the screw rod 313, and drives all the connecting rods 332 and the clamping plate 331 to move together, and approach the side of the steel structure rib 6 until the clamping plate 331 fits with the side of the steel structure rib 6, so that the steel structure rib 6 is clamped and fixed between the positioning seat 321 and the clamping plate 331, and the driving motor 312 stops forward rotation to complete the synchronous clamping and fixing of all the steel structure ribs 6, and then the connection side of the steel structure rib 6 and the steel structure trunk 5 can be fixed. During welding operation, after the welding operation on one side is completed, the steel structure needs to be turned over to continue welding on the other side. At this time, the driving motor 312 rotates in the opposite direction. The ratchet 316 cannot rotate alone under the restriction of the pawl 317. Under the rotation of the driving motor 312, the screw rod 313, the driving body 314 and the entire placement component 32 can be driven to rotate together, and the clamping component 33 and the steel structure are turned upward together with the placement component 32. When the steel structure is turned over 180 degrees, one side of it contacts the positioning pad 22 at the other end, and the driving motor 312 rotates in the opposite direction. The motor 312 stops rotating, and the other side of the steel structure flips upward. Then, the external welding mechanism can be used to weld the other side of the steel structure. After welding is completed, the positioning pad 22 is separated from the main body 5 of the steel structure by rotating the adjusting rotating piece 21. Then, the driving motor 312 is controlled to continue to rotate 180 degrees in the opposite direction to restore the placement component 32, the clamping component 33 and the steel structure to their initial posture. Then, the driving motor 312 is rotated forward to release the clamping component 33 from fixing the steel structure. The steel structure can be removed and the entire welding operation is completed.

[0045] It can be seen that in the tooling fixture provided in the present invention, the rib clamping mechanism 3 is used in conjunction with the trunk clamping mechanism 2 to achieve the positioning of the entire spliced ​​steel structure. Different from the existing fixture, the rib clamping mechanism 3 provided in the present invention not only has the function of clamping and fixing the steel structure ribs 6, but also can drive the steel structure to flip and automatically adjust it to the welding posture on the other side. Through the adaptive design of the driving component 31, the placement component 32 and the clamping component 33, the difficulty of the current fixture being easily restricted and hindered by the relevant clamping and positioning structure when performing the flipping action is overcome, and there is no need for manual flipping action, and there is no need to contact the clamping effect of the steel structure when flipping, which replaces the manual flipping method, simplifies the cumbersome operation steps, is conducive to speeding up the welding speed of the steel structure, and reduces the workload of the staff to meet the actual welding operation requirements. In addition, the driving component 31 provided in the present invention can be used to drive the placing component 32 to flip when used in conjunction with the placing component 32, so as to realize the function of driving the steel structure to flip. When used in conjunction with the clamping component 33, the clamping component 33 can simultaneously clamp and fix all the steel structure ribs 6. The driving switching of the placing component 32 and the clamping component 33 can be realized only by controlling the driving mode of the driving component 31. It is very convenient to use and better adapts to the action change requirements during the welding process of the steel structure.

[0046] Embodiment 2

[0047] Please refer to Figure 12 to Figure 14In order to better meet the welding requirements of different spacings of the steel structure ribs 6 and to improve the flexibility of the use of the fixture, the present invention continues to optimize the technical solution based on the first embodiment, specifically: the steel structure splicing welding fixture also includes a spacing adjustment mechanism, which is connected to the placement component 32, and is used to adjust the equal spacing of several placement units so that the steel structure ribs 6 are evenly distributed according to the preset spacing. The equidistant adjustment mechanism 4 includes a cylinder 41, two end hinges and a plurality of intermediate hinges. The telescopic end of the cylinder 41 is fixed to one side of the mounting frame 311, and one end of the mounting frame 311 is fixed to a support column 322 located on the side. The inner bottom wall of the base 1 is provided with a slide groove 7. The bottom of the mounting frame 311 is slidably connected to the slide groove 7, and the end of the mounting frame 311 is fixed to the outer side of the support seat on the side. The bottom of the five support columns 322 are all rotatably installed with pulleys 44, and the pulley 44 is slidably connected to the slide groove 7. The two end hinges are respectively rotatably installed on the bottom of the two positioning seats 321 located on the side, and the three intermediate hinges are correspondingly rotatably installed on the bottom of the three positioning seats 321 located in the middle position, and the ends of every two intermediate hinges are rotatably connected, and the ends of the two end hinges are respectively rotatably connected to the ends of the two intermediate hinges on the side. The end hinge includes two first connecting rods 42 distributed in a herringbone shape, and the overlapping ends of the two first connecting rods 42 are hinged. The middle hinge includes two second connecting rods 43 distributed in an X shape, and the overlapping ends of the two second connecting rods 43 are hinged.

[0048] It should be noted that when the above-mentioned spacing adjustment mechanism is in use, the placement component 32 is in a retracted state by default, that is, all the placement monomers are brought together, and the spacing of the positioning seat 321 is adjusted to be consistent with the required spacing. At this time, the steel structure ribs 6 and the steel structure trunk 5 have not been placed yet. The cylinder 41 is extended, which can drive the end hinges connected thereto to start rotating, so that the ends of the two first connecting rotating rods 42 rotate and move closer together, and the angle between the two gradually becomes smaller, and respectively drives the two second connecting rotating rods 43 connected thereto to rotate together, so that the ends of the two second connecting rotating rods 43 rotate synchronously and move closer together. In this way, the corresponding placement component can be driven through the transmission action between the end hinges and the middle hinges. 32 is displaced the same distance. When the placement component 32 is displaced, the support column 322 slides along the slide groove 7, and the pulley 44 thereon rolls in the slide groove 7, which limits the positioning seat 321, so that the positioning seat 321 can move stably in a straight line. After the spacing movement of the positioning seat 321 is consistent with the required spacing, the control cylinder 41 stops extending. After the spacing of the placement component 32 is adjusted, the steel structure trunk 5 is first placed on the trunk clamping mechanism 2, and then the steel structure rib 6 is placed on the positioning seat 321. By moving the steel structure trunk 5, the steel structure trunk 5 and the steel structure rib 6 are in a preset connection posture, and finally the steel structure rib 6 is fixed by the clamping component 33.

[0049] It can be seen from this that the present invention can achieve the function of equidistant adjustment of the spacing of multiple positioning seats 321 by further setting up a spacing adjustment mechanism, so as to meet the welding requirements of steel structure ribs 6 with different spacings, thereby improving the adaptability and flexibility of the tooling fixture; in addition, the spacing adjustment mechanism can be well matched with the above-mentioned tooling fixture and will not affect the flipping and clamping action of the rib clamping mechanism 3.

[0050] An example of the present specific implementation mode is described above, but the present embodiment is not limited to the above-mentioned specific implementation mode, which is merely illustrative and not restrictive. A person skilled in the art may make many forms inspired by the present embodiment, all of which are protected by the present embodiment.
