Description

Technical Field

[0001] This utility model relates to the field of steel reinforcement floor decking processing technology, and in particular to a formwork welding machine. Background Technology

[0002] The truss floor deck includes a base plate 100 and a steel truss 200, which is welded and fixed to the base plate 100. The steel truss 200 comes in two forms: the first is a truss with a base, such as... Figure 1 As shown, the steel truss 200 includes web reinforcement 201, top chord reinforcement 202, and bottom chord reinforcement 203. The web reinforcement 201 has a base 204. During the production of the truss floor deck, after the steel truss 200 is welded, the base 204 is welded to the base plate 100, and finally, cement is poured to form the deck. When welding the steel truss 200 to the base plate 100, only the upper electrode of the welding machine needs to move up and down in coordination with the synchronous horizontal movement of the steel truss 200 and the base plate 100 to weld them sequentially, resulting in high welding efficiency. The second type is a truss without a base, such as... Figure 2 As shown, the bottom of the web reinforcement 201 of the steel truss 200 does not have a base 204. After the steel truss 200 is welded, multiple connecting seats 205 are set on the base plate 100. First, the connecting seats 205 are fixedly connected to the base plate 100. The connection method is generally detachable, such as bolt connection, so that the base plate 100 can be removed after pouring. Finally, the lower chord reinforcement 203 is welded to the connecting seats 205 to obtain the truss floor slab. This scheme transforms the welding of the steel truss 200 to the base plate 100 into the welding of the lower chord reinforcement 203 to the connecting seats 205, which is more convenient for welding and facilitates the disassembly of the base plate 100. Figure 3 As can be seen, along the length direction (X direction) of the base plate 100, the bottom ends of welding point 300 and web reinforcement 201 are both located on the extension line of the lower chord reinforcement 203. Since traditional welding machines can only move up and down to perform multi-point welding, the welding machine needs to rise above the top of the web reinforcement 201 after each welding point 300, and then descend back to the welding point during welding. This results in a large stroke of the welding machine, affecting welding efficiency. If the vertical movement distance of the welding machine is not changed, the steel truss 200 and the base plate 100 will still move horizontally synchronously. This will cause the upper electrode rod of the welding machine to interfere with the position of the web reinforcement 201 in front of the welding point 300 during movement, resulting in a collision. Therefore, manual avoidance is required during the welding process, which is time-consuming and labor-intensive, affecting welding efficiency. Utility Model Content

[0057] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0058] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0059] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0060] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0061] This utility model embodiment provides a template welding machine, such as Figure 3 and Figure 4 As shown, the template welding machine includes a frame 1 and a positioning device 2, a feeding device 3, and a welding device 4 mounted on the frame 1, suitable for welding templates. Figure 2 and Figure 3 The steel truss 200 and the base plate 100 shown are welded together, i.e., there is no base truss. During welding, the lower chord reinforcement 203 needs to be welded to the connecting seat 425. Figure 3 As shown, the connecting seat 425 is bolted to the base plate 100. The lower chord rib 203 is welded to the connecting seat 425. The bottom of the web rib 201 has no base 204. The welding point 300 and the bottom of the web rib 201 are both located on the extension line of the lower chord rib 203. Therefore, when the steel truss 200 and the base plate 100 move in the first direction (X direction), since the traditional welding electrode can only move up and down, the welding electrode and the web rib 201 will interfere with each other, affecting the welding efficiency. To solve this problem, in this embodiment, a moving avoidance component 43 is provided in the welding device 4. The moving avoidance component 43 is configured to drive the upper electrode component 42 to move in the second direction (Y direction) to avoid the moving movement of the steel truss 200, so as to achieve smooth and efficient welding.

[0062] like Figure 4 and Figure 11As shown, in order to solve the above-mentioned technical problems, this utility model provides a template welding machine. The template welding machine includes a frame 1, a positioning device 2, a feeding device 3 and a welding device 4. The positioning device 2 is disposed on the frame 1 and is used to position the bottomless truss and the base plate 100, including the end positioning of the bottomless truss and the base plate 100 at the initial position and the side guiding positioning during the welding process. The feeding device 3 is slidably mounted on the frame 1. The feeding device 3 is used for synchronous step-by-step conveying of the positioned bottomless truss and the base plate 100. The first direction is the length direction of the base plate 100 of the reinforced concrete floor slab, and the width direction of the base plate 100 is the second direction. The welding device 4 includes several sets of upper electrode assemblies 42 and moving avoidance assemblies 43. The upper electrode assemblies 42 are used to weld the bottomless truss to the connecting seat 425 on the base plate 100. During the lifting process after completing a welding point 300, the moving avoidance assemblies 43 can drive the upper electrode assemblies 42 on both sides of each bottomless truss to move away from each other, thus allowing the bottomless truss to pass smoothly. After the bottomless truss passes, the upper electrode assemblies 42 move closer together and are pressed down for welding, thus completing the welding cycle. The reinforced concrete truss 200 mentioned below refers to a bottomless truss.

[0063] like Figure 6 The frame 1 is provided with multiple sets of upper electrode assemblies 42. Each set of upper electrode assemblies 42 is arranged in a one-to-one correspondence with multiple steel trusses 200 to be welded on the base plate 100. Each set of upper electrode assemblies 42 includes two upper electrode assemblies 42. One upper electrode assembly 42 is arranged on each side of each steel truss 200. The moving avoidance assembly 43 is configured to drive the two upper electrode assemblies 42 in each set of upper electrode assemblies 42 to move closer to each other or further away from each other in a second direction.

[0064] by Figure 6 As shown in the example, six steel trusses 200 are provided on the base plate 100 along its width direction. Correspondingly, six sets of upper electrode assemblies 42 are provided on the frame 1, each set including two upper electrode assemblies 42. These two upper electrode assemblies 42 are respectively positioned directly above the welding points 300 on the steel trusses 200. As the base plate 100 drives the steel trusses 200 to move in a stepping motion along the first direction (X direction), the stepping distance is the distance between two adjacent welding points 300. Multiple welding points 300 on the same cross-section are simultaneously welded and formed below multiple upper electrode assemblies 42, resulting in high welding efficiency. The template welding machine provided in this embodiment can be used for welding and forming truss floor decks without bottom feet 204 at the bottom of the web reinforcement 201. Of course, it can also be used for welding and forming truss floor decks with bottom feet 204, except that the moving avoidance component 43 is not working or is not set, making the welding process simpler and more efficient, and improving the versatility of the template welding machine.

[0065] The template welding machine provided by this utility model, by setting a moving avoidance component 43, drives two upper electrode components 42 on both sides of the same steel truss 200 to move closer or further apart within a certain range, such as... Figure 6 As indicated by the hollow arrow and the oblique filled arrow. During welding, the two upper electrode assemblies 42, which are set on both sides of the steel truss 200 in each group, move closer to each other to align with the welding points 300 for welding operations. After welding multiple welding points 300 on a cross section is completed, the base plate 100 and the steel truss 200 move synchronously by a set distance. The two upper electrode assemblies 42 in the same group move away from each other along the second direction to avoid the web reinforcement 201. The base plate 100 and the steel truss 200 can move smoothly to the next welding section along the first direction for sequential welding. No manual assistance is required during the welding process, and there is no need to change the lifting action of the existing upper electrode assembly 42. This solves the problem of reduced welding efficiency caused by positional interference between the base plate 100 and the upper electrode assembly 42 during the stepping movement of the steel truss 200 and the upper electrode assembly 42. It is suitable for welding processes of steel trusses 200 without bottom feet 204 at the bottom of web reinforcement 201 and base plates 100. Without changing the structure of the upper electrode assembly 42, the welding efficiency is greatly improved.

[0066] It should be noted that the moving avoidance component 43 simultaneously drives multiple sets of upper electrode components 42 to move closer or further away from each other, so that the multiple sets of upper electrode components 42 move in a consistent manner, thereby improving the welding process efficiency.

[0067] In some embodiments, the moving avoidance assembly 43 includes an avoidance rack 431 and an avoidance gear 432. Two avoidance racks 431 are provided, spaced apart and parallel to each other, and both avoidance racks 431 extend along a second direction. Two upper electrode assemblies 42 in each set of upper electrode assemblies 42 are respectively disposed on the two avoidance racks 431. The avoidance gear 432 is rotatably disposed on the frame 1 and located between the two avoidance racks 431. The teeth of the two avoidance racks 431 are arranged opposite to each other and respectively mesh with the avoidance gear 432. When the avoidance gear 432 rotates, it can drive the two avoidance racks 431 to move in the opposite direction, so that the two upper electrode assemblies 42 in each set of upper electrode assemblies 42 move in the opposite direction.

[0068] like Figure 8As shown, two clearance racks 431 are arranged vertically at intervals, both extending along the Y-axis and parallel to each other. Two clearance racks 431 are simultaneously meshed on a clearance gear 432. When the clearance gear 432 rotates, or when either clearance rack 431 moves, it drives the two clearance racks 431 to move in opposite directions, i.e., the two clearance racks 431 move in the positive and negative Y-axis directions respectively. Based on this principle, two upper electrode assemblies 42 of the same group are respectively mounted on the two clearance racks 431, realizing relative movement between the two upper electrode assemblies 42 of the same group. Figure 8 As shown, in an embodiment with six groups of twelve upper electrode assemblies 42, the upper electrode assemblies 42 with odd numbers (1, 3, 5, 7, 9, and 11) are simultaneously connected to the lower clearance rack 431, while the upper electrode assemblies 42 with even numbers (2, 4, 6, 8, 10, and 12) are simultaneously connected to the upper clearance rack 431. This enables the synchronous clearance movement of multiple groups of upper electrode assemblies 42, improving production cycle time and welding efficiency.

[0069] In some embodiments, the avoidance rack 431 is provided with a plurality of rack segments 4311, and each rack segment 4311 is respectively connected to an avoidance gear 432.

[0070] like Figure 9 and Figure 10 As shown, in this embodiment, two rack segments 4311 are spaced apart along the length of the avoidance rack 431. The two avoidance racks 431 have the same structure, and an avoidance gear 432 meshes between corresponding rack segments 4311 on the two avoidance racks 431. Figure 8 Therefore, in the Y-axis direction, two clearance gears 432 support and transmit power between the clearance racks 431, which helps to improve the force balance and positional stability of the clearance racks 431. The two rack segments 4311 are spaced apart and preferably located at the trisection points. The length of the rack segment 4311 ensures that the clearance racks 431 and clearance gears 432 are always in a meshed state. Furthermore, limiting structures can be provided at both ends of each rack segment 4311 on the clearance racks 431 to prevent the two clearance racks 431 from disengaging from the clearance gears 432 after excessive movement.

[0071] In some embodiments, the moving avoidance component 43 further includes a lateral drive member 433, which is disposed on the frame 1. The output end of the lateral drive member 433 is connected to any one of the upper electrode components 42, any one of the avoidance racks 431, or any one of the avoidance gears 432. The lateral drive member 433 is configured to drive any one of the upper electrode components 42 or any one of the avoidance racks 431 to move in the second direction, or to drive the avoidance gear 432 to rotate, thereby causing the two upper electrode components 42 in the same group to move closer to each other or further away from each other.

[0072] By setting up a lateral drive component 433, the automatic control of the movement of the upper electrode assembly 42 to avoid the steel truss 200 can be achieved. The lateral drive component 433 is electrically driven and can perform reciprocating or forward / reverse motion (in which case a transmission component is needed at the output end of the lateral drive component 433 to convert the rotational motion into linear motion) to drive the upper electrode assembly 42. Figure 8 In the illustrated embodiment, the lateral drive component 433 is a cylinder. Of course, in other embodiments, a hydraulic cylinder or a linear motor can also be used, and the specific method is not limited. One end of the lateral drive component 433 is fixedly connected to one of the upper electrode components 42 in a group of upper electrode components 42. The output end of the lateral drive component 433 is connected to another upper electrode component 42 in the same group. Thus, when the output end of the lateral drive component 433 extends or retracts, the two upper electrode components 42 in the same group move away from or towards each other. At the same time, the two avoidance racks 431 connected to it drive two of the other two upper electrode components 42 in the remaining groups of upper electrode components 42 to move away from or towards each other. This achieves the synchronous expansion and avoidance of multiple groups of upper electrode components 42 with a single action of the lateral drive component 433, thereby improving work efficiency.

[0073] When the transverse drive 433 is mounted on the frame 1, the output end of the transverse drive 433 is connected to a clearance rack 431 to move. The clearance rack 431 drives the clearance gear 432 to rotate, and the clearance gear 432 drives another clearance rack 431 to move in the opposite direction, thereby driving the two upper electrode assemblies 42 in each set of upper electrode assemblies 42 to move closer or further away from each other synchronously.

[0074] When the lateral drive member 433 is connected to the avoidance gear 432, the lateral drive member 433 drives the avoidance gear 432 to rotate, and the two avoidance racks 431 meshing on the avoidance gear 432 move in opposite directions, thereby driving the two upper electrode assemblies 42 in each set of upper electrode assemblies 42 to move closer or further away from each other synchronously.

[0075] In some embodiments, the moving avoidance component 43 further includes a fourth slide rail 434 and a fourth slider 435. The fourth slide rail 434 extends along the second direction and is fixed on the frame 1. The fourth slider 435 is slidably mounted on the fourth slide rail 434. The upper electrode component 42 is disposed on the fourth slider 435. The output end of the transverse drive 433 is connected to any one of the upper electrode components 42.

[0076] By setting a fourth slide rail 434 and a fourth slider 435, the upper electrode assembly 42 is slidably mounted to the frame 1, thereby providing a stable sliding motion platform, namely the fourth slide rail 434, for the upper electrode assembly 42, which helps ensure the installation reliability and movement stability of the upper electrode assembly 42. Furthermore, multiple sets of upper electrode assemblies 42 are mounted on the same fourth slide rail 434 to ensure consistency. Multiple fourth sliders 435 are used, and the spacing between the fourth sliders 435 ensures that the movement of the upper electrode assembly 42 is mutually complementary. When multiple fourth slide rails 434 are provided, the multiple fourth slide rails 434 along the Y direction are parallel to each other.

[0077] In some embodiments, two fourth slide rails 434 are provided, and the two fourth slide rails 434 are respectively disposed on both sides of the upper electrode assembly 42 along the first direction. Two fourth sliders 435 on the two fourth slide rails 434 are provided with transition plates 436, and the upper electrode assembly 42 is disposed on the transition plates 436.

[0078] like Figure 7 As shown, along the first direction X, which is also the stepping direction of the base plate 100 and the steel truss 200, there are two slide rails. Two fourth slide rails 434 are respectively located on the front and rear sides (on both sides along the X direction) of multiple sets of upper electrode assemblies 42. Each upper electrode assembly 42 can be connected to two fourth sliders 435 positioned opposite each other on the two fourth slide rails 434, thereby improving the directionality and stability of the sliding movement of the upper electrode assembly 42. Furthermore, the two fourth sliders 435 can better mount the upper electrode assembly 42, avoiding instability that could affect welding accuracy. Figure 7 As shown, the fourth slide rail 434 and the fourth slider 435 have irregular cross sections (such as I-shaped or T-shaped cross sections) that cooperate with each other. When the fourth slider 435 is slidably installed with the fourth slide rail 434, the upper electrode assembly 42 is also slidably installed on the fourth slide rail 434.

[0079] In some embodiments, the upper electrode assembly 42 includes an electrode fixing base 421, a fourth lifting drive member 422, and an electrode seat 423. The electrode fixing base 421 is slidably mounted on the frame 1 and connected to the movement avoidance component 43. The electrode fixing base 421 is the body of the upper electrode assembly 42. When the electrode fixing base 421 slides on the frame 1, under the action of the movement avoidance component 43, the two upper electrode assemblies 42 in the same group move closer or further apart under the drive of the electrode fixing base 421. The fourth lifting drive member 422 is disposed on the electrode fixing base 421. The output end of the fourth lifting drive member 422 passes vertically downward through the electrode fixing base 421 and can move telescopically. The electrode seat 423 is fixedly connected to the output end of the fourth lifting drive member 422. The electrode seat 423 is provided with a circular electrode 424 for welding, thereby realizing the working control of the upper electrode assembly 42's vertical displacement for welding.

[0080] like Figure 11 As shown, the electrode holder 421 is provided with a connecting seat 425. The body of the fourth lifting drive component 422 is fixed on the connecting seat 425. The electrode holder 421 is fixed on the transition plate 436. The electrode holder 421 is connected to the avoidance rack 431 of the moving avoidance component 43 and can move together with the moving avoidance component 43, so that the entire upper electrode component 42 can realize the avoidance function along the Y direction. The output end of the fourth lifting drive component 422 is vertically downward and slides through the inner cavity of the electrode holder 421. The output end of the fourth lifting drive component 422 is provided with a guide post, which can increase the length of the output end of the fourth lifting drive component 422 to facilitate the installation of the electrode seat 423. A round electrode 424 is provided on the electrode seat 423 for welding with the welding point 300. The fourth lifting drive component 422 can be a linear drive component such as a cylinder or an electric cylinder.

[0081] In some embodiments, the bottom end of the electrode holder 421 is disposed on the transition plate 436 and is fixedly connected to the transition plate 436; the side of the electrode holder 421 is provided with two mounting positions in the vertical direction, and two clearance racks 431 are selectively installed in one of the mounting positions; the top end of the electrode holder 421 is fixedly connected to the output end of the transverse drive member 433.

[0082] For example Figure 7 Generally, the transition plate 436 is provided with clearance holes. The guide rod 426 and the electrode seat 423 pass through the clearance holes and are located below the transition plate 436. The bottom end face of the electrode fixing seat 421 abuts against the upper surface of the transition plate 436 and is then fixedly connected by bolts. The side of the electrode fixing seat 421 is provided with a first mounting position 4211 and a second mounting position 4212, which are combined with... Figure 6 For odd-numbered upper electrode assemblies 42, the lower clearance rack 431 is fixedly connected to the lower second mounting position 4212 on the electrode mounting base 421. For even-numbered upper electrode assemblies 42, the upper clearance rack 431 is fixedly connected to the upper first mounting position 4211 on the electrode mounting base 421, realizing relative motion control of the two upper electrode assemblies 42 in the same group. The fixed connection method can be bolt connection. When the transverse drive member 433 is connected to the upper electrode assembly 42, the body of the transverse drive member 433 can be fixed on the frame 1, and the output end of the transverse drive member 433 is connected to the electrode mounting base 421 or the connecting seat 425 on the electrode mounting base 421, realizing the drive of the upper electrode assembly 42. This achieves the sliding installation of the upper electrode assembly 42.

[0083] In some embodiments, the template welding machine further includes a transformer 41, which is mounted on the frame 1 and connected to the upper electrode assembly 42 via a flexible wire 411.

[0084] like Figure 7As shown, transformer 41 is mounted on frame 1 and is used to transmit current to upper electrode assembly 42. Since upper electrode assembly 42 has a moving motion along the Y direction, flexible wire 411 is provided to facilitate the moving motion of upper electrode assembly 42. The length of flexible wire 411 needs to meet the requirement of reliable connection of upper electrode assembly 42 during movement.

[0085] Using the template welding machine provided by this utility model, for Figure 2 The truss floor slab, composed of the steel truss 200 and the base plate 100, is welded together. The web members 201 lack a base 204 at their bottom, requiring the lower chord members 203 of the steel truss 200 to be welded to the connecting seats 425 on the base plate 100. The connecting seats 425 are located at the center of the lower chord members 203 between two adjacent web members 201. During welding, the two upper electrode assemblies 42 on both sides of a steel truss 200 press down on the lower chord members 203 on both sides of the steel truss 200. After the lower chord members 203 abut against the connecting seats 425, a closed circuit is formed due to the conductivity of the connecting seats 425, generating resistance heat and forming a welding point 300 between the lower chord members 203 and the connecting seats 425, thus achieving a welded connection. When the base plate 100 and the steel truss 200 move in a stepping motion to weld the next set of welding points 300, the upper electrode assembly 42 and the web reinforcement 201 will interfere with each other. Therefore, when the electrode seat 423 moves upward after the upper electrode assembly 42 has finished welding a welding point 300, the moving avoidance assembly 43 is activated. The lateral drive component 433 drives one upper electrode assembly 42, and the remaining upper electrode assemblies 42 move away from each other under the action of the avoidance rack 431 and the avoidance gear 432. At the same time, the upper and lower connecting seats 425 of the base plate 100 and the steel truss 200 move in a stepping motion to the bottom of the upper electrode assembly 42. This cycle is repeated to complete the welding.

[0086] It is understandable that during the welding process, the moving avoidance component 43 drives the upper electrode components 42 to move closer or further away from each other, the electrode seat 423 on each upper electrode component 42 moves up and down, and the base plate 100 and the steel truss 200 move in a stepping motion along the X direction. The three movements are carried out simultaneously. By reasonably setting the moving speed and rhythm, the forming efficiency of the truss floor deck can be greatly improved.

[0087] In some embodiments, such as Figure 5 The positioning device 2 includes a base plate positioning mechanism 22, a steel truss positioning mechanism 21, and an end positioning mechanism 23. Two base plate positioning mechanisms 22 are provided, and are respectively positioned on both sides of the fixed welding position along the first direction (X direction). Figure 5The upper electrode assembly 42 has two sides along the X direction. The base plate positioning mechanism 22 can support the base plate 100 and abut against the base plate 100 for limiting. The steel truss positioning mechanism 21 is located above at least one base plate positioning mechanism 22. The steel truss positioning mechanism 21 includes a positioning block 214 and a first lifting drive member 213. The positioning block 214 is located at the output end of the first lifting drive member 213. The first lifting drive member 213 is configured to drive the positioning block 214 to move up and down, so that the positioning block 214 can position the steel truss 200 and press it onto the base plate 100. The end positioning mechanism 23 includes a first baffle 233 and a second lifting drive member 232. The second lifting drive member 232 is configured to drive the first baffle 233 to move up and down to position the end face of the bottomless truss and / or the end face of the base plate 100.

[0088] like Figure 1 and Figure 12 As shown, the first lifting drive component 213 is a linear drive component such as a cylinder. The number of the first lifting drive component 213 and the number of positioning blocks 214 are matched with the number of steel trusses 200 to facilitate simultaneous positioning of each steel truss 200. In this embodiment, six first lifting drive components 213 are spaced apart on the pressing connection plate 212 and correspond one-to-one with the standard positions of the six steel trusses 200. The two ends of the pressing connection plate 212 are respectively fixed on two pressing supports 211, and the bottom ends of the two pressing supports 211 are fixed on the frame 1. The output end of the first lifting drive component 213 is downward and connected to the positioning block 214. Preferably, the positioning block 214 is correspondingly set with the steel truss 200. Each positioning block 214 is provided with a V-groove 2141. The V-groove 2141 is adapted to the connection position of the upper chord bar 202 and the web bar 201 of the steel truss 200 for pressing. After the base plate 100 is positioned by the base plate positioning mechanism 22, the position of the steel truss 200 above the base plate 100 may deviate slightly from the required standard position. At this time, by moving the positioning block 214 downwards, the V-groove 2141 gradually contacts the connection point (highest position, or only the upper chord 202) of the steel truss 200. Through the V-groove 2141, the position of the steel truss 200 can be aligned, achieving the purpose of positioning the steel truss 200. Pressing the positioning block 214 onto the steel truss 200 during welding can also prevent the steel truss 200 from warping during welding, thereby improving welding quality. Furthermore, the steel truss positioning mechanism 21 also includes a fifth lifting drive component 215. In this embodiment, the fifth lifting drive component 215 is a manual drive component; however, pneumatic or electric drive mechanisms such as cylinders can also be used. Figure 12When the fifth lifting drive component 215 is a manual drive component, the fifth lifting drive component 215 includes a handwheel 2151 and a lead screw 2152. The handwheel 2151 is fixed to the top of the lead screw 2152, and the bottom of the lead screw 2152 transmits the pressure support 211 and is threadedly connected to the pressure connecting plate 212. At this time, the pressure connecting plate 212 and the pressure support 211 are slidably connected through the guide rail slider. The handwheel 2151 drives the lead screw 2152 to rotate, and the pressure connecting plate 212 moves up and down along the pressure support 211, thereby increasing the height adjustment range of the positioning block 214 and making it more widely applicable.

[0089] like Figure 5 As shown, along the first direction (X direction), two base plate positioning mechanisms 22 are used to provide double limiting and support for the base plate 100 during the welding process, ensuring stable movement of the base plate 100 during stepping and stable support during welding. The two base plate positioning mechanisms 22 are a front base plate positioning mechanism 22 and a rear base plate positioning mechanism 22, which can adopt the same structure. The front base plate positioning mechanism 22 is used to position the base plate 100 to be welded, so that the base plate 100 is in a suitable position. The rear base plate positioning mechanism 22 is installed at the rear end of the frame 1, downstream of the stepping direction of the base plate 100, and is used to support and position the welded baseless truss and base plate 100.

[0090] like Figure 13 As shown, taking one of the base plate positioning mechanisms 22 as an example, the base plate positioning mechanism 22 includes a roller seat 221 and positioning elements 222. The roller seat 221 is mounted on the frame 1, and multiple conveying rollers 223 are rotatably mounted on the roller seat 221 to roll and support the base plate 100. The conveying rollers 223 can reduce the frictional resistance during the conveying process of the base plate 100. Multiple positioning elements 222 are provided, and each positioning element 222 is adjustablely positioned on the roller seat 221. Figure 13 As shown, four positioning components 222 are disposed between three conveying rollers 223. Each positioning component 222 includes an adjusting seat 2221, an adjusting shaft 2222, and a positioning bearing 2223. The adjusting seat 2221 is adjustablely disposed on the roller seat 221. The adjusting seat 2221 includes a fixed part and an adjustable part. The fixed part is fixed on the roller seat 221, and the adjustable part is connected to the fixed part by a screw and bolt. The adjustable part is slidably installed on the roller seat 221, and the sliding direction is along the width direction of the base plate 100 to facilitate adjustment to adapt to the width specifications of the base plate 100. The adjusting shaft 2222 and the adjustable part are adjustable along the height direction (Z direction). The positioning bearing 2223 is fixedly disposed on the adjusting shaft 2222, so that the height of the positioning bearing 2223 can be adjusted by the adjusting shaft 2222 to allow the positioning bearing 2223 to abut against the base plate 100 for positioning.

[0091] like Figure 14The end positioning mechanism 23 includes a second lifting drive 232 and a first baffle 233. The second lifting drive 232 is fixedly installed below the frame 1 through a baffle positioning bracket 231. The baffle positioning bracket 231 is fixedly installed on the frame 1 and located below the bottom plate 100 to be welded. The second lifting drive 232 is installed on the baffle positioning bracket 231. The output end of the second lifting drive 232 extends vertically upward (along the Z direction) through the baffle positioning bracket 231 to protrude above the frame 1. The first baffle 233 is fixedly connected to the output end of the second lifting drive 232 for lifting and lowering movement. The first baffle 233 is used for the initial positioning of the steel truss 200 and the base plate 100. When the steel truss 200 and the base plate 100 are conveyed forward, the second lifting drive 232 drives the first baffle 233 to rise. When the steel truss 200 and the base plate 100 are conveyed to the first baffle 233, their ends are blocked by the first baffle 233. At this time, the initial position of the steel truss 200 and the base plate 100 is positioned. The initial position is such that the first weld point of the steel truss 200 and the base plate 100 is located in the fixed welding position. After the positioning is completed, the second lifting drive 232 drives the first baffle 233 to descend, and the welding device 4 begins welding. The first baffle 233 does not affect the stepping conveying of the steel truss 200 and the base plate 100. The second lifting drive 232 is a linear drive mechanism such as a cylinder.

[0092] For some reinforced concrete floor slabs where the ends of the steel truss 200 protrude from the base plate 100 for welding, in this embodiment, a second baffle 234 is detachably installed on the first baffle 233. The first baffle 233 and the second baffle 234 respectively abut against the end face of the steel truss 200 and the end face of the base plate 100. The second baffle 234 is located on the side of the first baffle 233 facing the material feeding direction of the steel truss 200 and the base plate 100. When the steel truss 200 and the base plate 100 are conveyed, the end of the base plate 100 preferentially abuts against the second baffle 234. At this time, the end of the steel truss 200 has not yet contacted the first baffle 233. When the steel truss 200 continues to be conveyed forward, the end of the steel truss 200 abuts against the first baffle 233, at which time the end of the steel truss 200 protrudes from the end of the base plate 100. Of course, if the steel truss 200 is not required to protrude from the end of the base plate 100, the second baffle 234 can be removed. The distance between the first baffle 233 and the second baffle 234 is preset according to the distance by which the end of the steel truss 200 protrudes from the base plate 100.

[0093] In some embodiments, the feeding device 3 includes a first stepping mechanism 31 and a second stepping mechanism 32, along a first direction, such as... Figure 5 The first stepping mechanism 31 and the second stepping mechanism 32 are respectively located at the front and rear ends of the fixed welding position of the welding device 4 and are both fixed on the frame 1.

[0094] Among them, such as Figure 15The first stepping mechanism 31 includes a first sliding plate 311 and a first clamping mechanism 312. The first sliding plate 311 is slidably mounted on the frame 1 and located upstream of the welding device 4. The first clamping mechanism 312 is provided on the first sliding plate 311 and is used to clamp the base plate 100. The first sliding plate 311 can drive the bottomless truss and the base plate 100 to step along a first direction. Figure 16 The second stepping mechanism 32 includes a second sliding plate 321 and a second clamping mechanism 322. The second sliding plate 321 is slidably mounted on the frame 1 and located downstream of the welding device 4. The second clamping mechanism 322 is provided on the second sliding plate 321 and is used to clamp and fix the base plate 100. The second sliding plate 321 can drive the bottomless truss and the base plate 100 to step along the first direction. Due to the positional relationship, the first clamping mechanism 312 cannot clamp the bottomless truss and the base plate 100 in the last step of welding. Therefore, the last step of welding of the bottomless truss and the base plate 100 is achieved by clamping and stepping through the second clamping mechanism 322 on the second sliding plate 321.

[0095] like Figure 15 As shown, a first clamping mechanism 312 is provided at both ends of the first sliding plate 311 along the second direction, and a second clamping mechanism 322 is provided at both ends of the second sliding plate 321 along the second direction. The first clamping mechanism 312 and the second clamping mechanism 322 are used to clamp the bottomless truss and the base plate 100 respectively. The first stepping mechanism 31 is used to synchronously feed and clamp the bottomless truss and the base plate 100 from the first welding point 300 to the penultimate welding point 300. The second stepping mechanism 32 is located downstream of the first stepping mechanism 31 and is used for clamping and stepping when the bottomless truss and the base plate 100 are welded at the last welding point 300. Furthermore, during the automatic welding process, before the first stepping mechanism 31 returns to its original position, the second clamping mechanism 322 on the second stepping mechanism 32 first clamps the bottomless truss and the base plate 100. Subsequently, the first clamping mechanism 312 on the first stepping mechanism 31 releases the clamping of the bottomless truss and the base plate 100 to prevent the bottomless truss and the base plate 100 from being displaced by friction. That is, the first stepping mechanism 31 and the second stepping mechanism 32 alternately clamp the base plate 100. Before the first stepping mechanism 31 prepares to step forward, the first clamping mechanism 312 on the first stepping mechanism 31 will first clamp the bottomless truss and the base plate 100. Then, the second clamping mechanism 322 on the second stepping mechanism 32 will release the clamping of the bottomless truss and the base plate 100. That is, during the stepping and welding process of the bottomless truss and the base plate 100, one of the first clamping mechanism 312 and the second clamping mechanism 322 will always clamp the bottomless truss and the base plate 100 to ensure the welding effect of the bottomless truss and the base plate 100.

[0096] Specifically, such as Figure 15The first stepping mechanism 31 also includes a first stepping drive member 313, which is mounted on the frame 1. The first slide plate 311 is slidably connected to the frame 1, and the first stepping drive member 313 drives the first slide plate 311 to slide linearly relative to the frame 1. The first clamping mechanism 312 is mounted on the first slide plate 311 and can move synchronously with the first slide plate 311. With this structure, when the first clamping mechanism 312 clamps the bottomless truss and the base plate 100, the first stepping drive member 313 drives the first slide plate 311 to slide, and at the same time drives the first clamping mechanism 312 mounted on the first slide plate 311 and the bottomless truss and the base plate 100 clamped by the first clamping mechanism 312 to slide synchronously, so that the bottomless truss and the base plate 100 move synchronously to the welding device 4.

[0097] In this embodiment, the first stepper drive component 313 is a motor, which is mounted on a motor bracket 314. The motor bracket 314 is mounted on the front end of the frame 1. The output end of the motor can be connected to the first end of the ball screw 316 via a coupling 315. Screw support seats 3161 are provided on both sides of the motor bracket 314. The ball screw 316 is rotatably passed through the screw support seats 3161. The second end of the ball screw 316 is threadedly connected to the stepper screw female seat 3162. The stepper screw female seat 3162 is fixedly connected to the first slide plate 311. First sliders 3111 are provided at the bottom of both sides of the first slide plate 311. A first slide rail 3112 is provided on the frame 1. The first slide rail 3112 is parallel to the axis of the ball screw 316. The first sliders 3111 are slidably disposed on the first slide rail 3112. When the motor drives the ball screw 316 to rotate, the stepper screw mother seat 3162 moves linearly relative to the ball screw 316, which in turn drives the first slide plate 311 to move linearly. At this time, the first clamping mechanism 312 installed on the first slide plate 311, as well as the steel truss 200 and the base plate 100 clamped by the first clamping mechanism 312, will also be driven to move.

[0098] In this embodiment, the arrangement of the first slider 3111 and the first slide rail 3112 not only restricts the rotational movement of the first slide plate 311 around the rotation axis of the ball screw 316, ensuring that the first slide plate 311 moves only in the axial direction of the rotation axis of the ball screw 316, but also effectively reduces the friction during the movement and reduces energy loss.

[0099] Preferably, two sets of sliding components are added below the center of the first slide plate 311. Each sliding component includes a second slide rail 317 and a second slider. The second slide rail 317 is parallel to the first slide rail 3112. The second slide rail 317 is mounted on the frame 1, and the second slider is slidably mounted on the second slide rail 317. The second slider is fixedly mounted on the bottom surface of the first slide plate 311. The addition of the second slide rail 317 reduces the impact on the first slide plate 311. Preferably, as... Figure 15The first step mechanism 31 also includes a first support roller 319, which is rotatably mounted on the first slide plate 311. The first support roller 319 is used to assist the first slide plate 311 in rolling and supporting the base plate 100, thereby reducing the friction between the base plate 100 and the first slide plate 311.

[0100] In this embodiment, the motor can be a servo motor. Compared with ordinary motors, servo motors have the advantages of controllability and high precision. Moreover, servo motors have a fast response speed and can frequently reverse direction to adjust the position of the first slide plate 311. The axis of the output shaft of the motor coincides with the axis of the ball screw 316.

[0101] It is understood that the first stepper drive 313 in this embodiment can also be a cylinder, and the output end of the cylinder is connected to the first slide plate 311 to drive the first slide plate 311 to move.

[0102] like Figure 16 As shown, the second stepping mechanism 32 also includes a second stepping drive 323, which is mounted on the frame 1. The second slide plate 321 is slidably connected to the frame 1, and the second stepping drive 323 drives the second slide plate 321 to slide linearly relative to the frame 1. The second clamping mechanism 322 is mounted on the second slide plate 321 and can slide with the second slide plate 321. With this structure, when the second clamping mechanism 322 clamps the bottomless truss and the base plate 100, the second stepping drive 323 drives the second slide plate 321 to slide, simultaneously driving the second clamping mechanism 322 mounted on the second slide plate 321 and the bottomless truss and the base plate 100 clamped by the second clamping mechanism 322 to step synchronously.

[0103] For example, the second stepper drive 323 is a cylinder, which is mounted on a first cylinder holder 324. The first cylinder holder 324 is mounted at the rear end of the frame 1. The output end of the cylinder is connected to a connecting shaft 326 via a fisheye bearing 325. The axis of the connecting shaft 326 is perpendicular to the axis of the cylinder output end. The second slide plate 321 is fixed to the connecting shaft 326. By extending or retracting the cylinder, the second slide plate 321 can be driven to move linearly.

[0104] Preferably, a third slider 3211 is provided on both sides of the bottom of the second slide plate 321, and a third slide rail 3212 is provided on the frame 1. The third slider 3211 slides on the third slide rail 3212, and the third slide rail 3212 is parallel to the axis of the output end of the second stepper drive 323.

[0105] The first stepping mechanism 31 and the second stepping mechanism 32 described above can employ the same drive structure to drive the first slide plate 311 and the second slide plate 321 to slide on the frame 1, respectively. Further, as... Figure 16A second support roller 327 is rotatably mounted on the second slide plate 321. The second support roller 327 is used to roll and support the base plate 100, reducing the friction between the base plate 100 and the second slide plate 321.

[0106] In some embodiments, the first clamping mechanism 312 and the second clamping mechanism 322 adopt the same structure, with two first clamping mechanisms 312 disposed on the first slide plate 311 and two second clamping mechanisms 322 disposed on the second slide plate 321. Taking the first clamping mechanism 312 disposed on the first slide plate 311 as an example, ... Figure 17 The first clamping mechanism 312 includes a clamping fixing seat 3121, a third lifting drive member 3122, an upper pressure plate 3123, and a lower pressure plate 3124. The clamping fixing seat 3121 is located on the first sliding plate 311, and a guide shaft 3125 is provided on the clamping fixing seat 3121. The third lifting drive member 3122 is located at the top of the guide shaft 3125, and the output end of the third lifting drive member 3122 is vertically downward. The upper pressure plate 3123 is located at the output end of the third lifting drive member 3122, and a pressure block 3126 is provided on the lower surface of the upper pressure plate 3123. The lower pressure plate 3124 is located on the first sliding plate 311, and the lower pressure plate 3124 is positioned directly opposite the pressure block 3126. The third lifting drive member 3122 drives the pressure block 3126 to descend and press the bottomless truss and the base plate 100 onto the lower pressure plate 3124.

[0107] like Figure 17 In this embodiment, taking the third lifting drive component 3122 as an example, the cylinder is a pressure plate cylinder, which is mounted on the clamping and fixing seat 3121 via four guide shafts 3125 and two cylinder connecting plates 3127. The two clamping and fixing seats 3121 are symmetrically arranged on the first sliding plate 311. The pressure plate cylinder can drive the upper pressure plate 3123 to move up and down, pressing down and lifting up. The four guide shafts 3125 pass through the upper pressure plate 3123 to provide a guiding function.

[0108] During the automatic welding process, when the second clamping mechanism 322 on the second stepping mechanism 32 clamps the bottomless truss and the base plate 100, the steel truss positioning mechanism 21 simultaneously clamps and positions the bottomless truss.
