Description

Technical Field

[0001] This utility model belongs to the field of steel structure processing technology, and in particular relates to a steel structure stud feeding and welding integrated machine. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. They are mainly composed of steel beams, steel columns, steel trusses, and other components made of steel sections and plates. In steel structures, stud welding is a common connection method. By using specialized methods such as arc stud welding, studs are precisely welded between the steel components to enhance the strength of the steel structure.

[0003] However, most steel structure stud welding machines on the market currently have limited functionality, generally only possessing basic welding capabilities. In actual welding operations, the loading process relies on manual placement of studs one by one into designated positions. This traditional loading method significantly reduces welding efficiency. When faced with large-scale steel structure welding tasks, a significant amount of time is wasted on repetitive loading actions, resulting in a slow welding process that fails to meet the requirements of modern engineering construction for efficient construction. Secondly, the accuracy of manual loading is difficult to guarantee. Due to human error, stud placement is prone to deviation, which in turn affects welding quality, leading to stress concentration and weak connections at the welded parts, thus posing potential risks to the safety and stability of the structure.

[0004] Therefore, there is a particular need for a steel structure stud feeding and welding integrated machine to solve the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of most steel structure stud welding machines on the market, such as limited functionality, reliance on manual feeding leading to low welding efficiency and slow process, poor accuracy of manual feeding which easily leads to welding quality problems and poses hidden dangers to structural safety and stability, this utility model provides a steel structure stud feeding and welding integrated machine.

[0006] This utility model is achieved through the following technical approach: A steel structure stud feeding and welding integrated machine includes a base plate, a vertical frame, a first electric slide rail, an electric sliding plate, a welding assembly, a second electric slide rail, a loading platform, a clamping assembly, and a controller. The vertical frame is fixed to one side of the top of the base plate. Two first electric slide rails are vertically distributed and installed on one side of the upper part of the vertical frame. The electric sliding plate is slidably disposed between the two first electric slide rails. The welding assembly is disposed on one side of the electric sliding plate. Two second electric slide rails are arranged side by side and installed at the top of the base plate, located in front of the vertical frame. The loading platform is slidably disposed between the two second electric slide rails. The clamping assembly is disposed between the vertical frame and the loading platform. The controller is installed on one side of the upper part of the vertical frame. The device is electrically connected to the first electric slide rail, electric slide plate, welding assembly, second electric slide rail, and loading platform. It also includes a conveyor, limiting plates, limiting rods, and nuts. The conveyor is installed on one side of the base plate and electrically connected to the controller. Two limiting plates are arranged side by side and fixed to the upper part of the conveyor. Each limiting plate has two sliding grooves distributed to the left and right at its top. Each limiting rod is slidably disposed inside each sliding groove, with one end extending to the outside of the sliding groove. The cylindrical surfaces at the upper ends of every two longitudinally aligned limiting rods face each other. Each nut is threaded on the threaded portion at one end of each limiting rod, with its bottom surface and the lowest point of the thread at the same level, while forming a tight rotational contact with the top surface of the limiting plate.

[0007] In a preferred embodiment of this utility model, the welding assembly includes a first guide rod, a motor, a lead screw, an electric slide, a welding gun, a double-headed cylinder, and clamping blocks. Two first guide rods are arranged side by side on one side of the electric slide. The motor, which is electrically connected to the controller, is installed on the upper side of the electric slide with its output shaft facing downward. The two first guide rods are located on both sides of the motor. One end of the lead screw is fixed to the output shaft of the motor through a coupling. The electric slide is slidably arranged between the two first guide rods and forms a threaded engagement with the lead screw. The welding gun is installed on one side of the electric slide. The double-headed cylinder is installed at the lower part of the welding gun, with two telescopic ends extending forward and backward respectively. Each telescopic end is fixed with a clamping block. Both the welding gun and the double-headed cylinder are electrically connected to the controller. The contact surface of each clamping block is designed as an arc-shaped structure.

[0008] In a preferred embodiment of this utility model, the clamping assembly includes clamping plates, second guide rods, springs, wedge blocks, guide strips, and screws. Two clamping plates are slidably disposed on the loading platform, facing each other. Multiple second guide rods are distributed and fixedly connected to the loading platform along a rectangular direction. Each clamping plate is slidably connected to two longitudinally aligned second guide rods. Each spring is sleeved on the outside of each second guide rod, with its two ends fixedly connected to the loading platform and the corresponding clamping plate, respectively. Each wedge block is fixed to one side of each clamping plate. Two guide strips are arranged side-by-side. The sliding distribution is located at the lower part of the upright. Each guide bar has an inclined surface and a straight surface. The inclined surface at one end of the guide bar corresponds to the inclined surface on one side of the adjacent wedge block, and the straight surface is in close contact with one side of the corresponding clamping plate. Two screws are arranged side by side with threads at the lower part of the upright and are rotatably connected to the other end of the two guide bars respectively. Each screw extends to one end of the upright and is equipped with two circular blocks. The circular block on one side is in close contact with the surface of the upright and serves to limit the movement range of the screw, while the circular block on the other side serves as the knob of the screw.

[0009] In a preferred embodiment of the present invention, a cam follower is further included. Each cam follower is rotatably disposed at the sharp corner position at one end of each wedge block. A certain gap is reserved between the guide strip and the adjacent inclined surface of the wedge block. This gap serves as the accommodating space for the cam follower. The rolling surface of the cam follower is tightly attached to the inclined surface at one end of the adjacent guide strip, and the two achieve rolling cooperation.

[0010] In a preferred embodiment of the present invention, it further includes guide blocks, two guide blocks are fixedly connected to the lower part of the upright in a horizontal row, and the guide strip and the guide blocks are in sliding contact in a one-to-one correspondence.

[0011] In a preferred embodiment of this utility model, one end of each limiting rod consists of a cylindrical part and a handle part. The cylindrical surface of the cylindrical part is used as the limiting surface, while the handle part is used as the force point of the limiting rod.

[0012] Beneficial effects: 1. By setting up a feeding and limiting mechanism consisting of a conveyor, a limiting plate, a limiting rod and a nut, the feeding speed and spacing of the studs can be precisely controlled, ensuring that each stud can be accurately clamped by the clamping block in a suitable posture and position, achieving a stable feeding process. Operators only need to place a batch of studs every once in a while, which greatly reduces the intensity of manual monitoring and also reduces production errors caused by human operation mistakes.

[0013] 2. By setting a screw in the clamping assembly to adjust the position of the guide bar, the clamping plate is pushed to clamp the steel structure. This method can keep the clamping force stable and adjustable, adapt to steel structures of different specifications, ensure the stability of the steel structure during welding, and thus improve the welding quality.

[0022] Example: A steel structure stud feeding and welding integrated machine, such as Figures 1-7As shown, the system includes a base plate 1, a support frame 2, first electric slide rails 3, an electric sliding plate 4, a welding assembly, second electric slide rails 16, a loading platform 17, a clamping assembly, and a controller 26. The support frame 2 is welded to the rear top of the base plate 1. Two first electric slide rails 3 are bolted vertically to the front upper part of the support frame 2. The electric sliding plate 4 is slidably positioned between the two first electric slide rails 3, enabling linear movement in the left and right directions under the drive of the two first electric slide rails 3. The welding assembly is located on the front side of the electric sliding plate 4. Two second electric slide rails 16 are bolted side-by-side to the top of the base plate 1, located in front of the support frame 2. The loading platform 17 is slidably positioned between the two second electric slide rails 16. Between the upright 2 and the loading platform 17, a clamping assembly is disposed. A controller 26 is bolted to the upper right side of the upright 2 and electrically connected to the first electric slide rail 3, the electric slide plate 4, the welding assembly, the second electric slide rail 16, and the loading platform 17. The system also includes a conveyor 13, limiting plates 14, limiting rods 15, and nuts 151. The conveyor 13 is bolted to the right side of the base plate 1 and electrically connected to the controller 26. Two limiting plates 14 are welded side-by-side to the upper part of the conveyor 13. Each limiting plate 14 has two left-right oriented grooves 141 at its top. Each limiting rod 15 is slidably disposed inside each groove 141, with its upper end extending into the groove 141. The upper cylindrical surfaces of each pair of longitudinally aligned limiting rods 15 are arranged facing each other (i.e., close to each other, both facing inwards). The upper end of each limiting rod 15 consists of a cylindrical part and a handle part. The cylindrical surface of the cylindrical part serves as a limiting surface (i.e., to limit the conveying speed of the studs). When the studs pass through the limiting rods 15 during conveying, they will slide in contact with the cylindrical surface of the cylindrical part. The friction and resistance generated by this contact cause the studs to pause briefly, ensuring that each stud maintains an appropriate distance, creating favorable conditions for the subsequent clamping block 12 to accurately clamp the studs, and ensuring the stability and orderliness of the entire feeding process. The handle part serves as the force point of the limiting rods 15. Nut 151 is threaded on the threaded portion at the upper end of each limiting rod 15, with its bottom surface at the same level as the lowest point of the thread. It also forms a tight rotational contact with the top surface of the limiting plate 14. In the initial state, nut 151 locks the limiting rod 15 by means of its contact with the limiting plate 14, preventing the limiting rod 15 from moving accidentally and ensuring the stability of the position of the limiting rod 15. When it is necessary to adjust the position of the limiting rod 15 according to the actual situation, simply rotate nut 151, and nut 151 will move upward along the direction of the threaded portion, thereby disengaging from the contact with the limiting plate 14, releasing the locking of the limiting rod 15, and facilitating subsequent position adjustment operations.

[0023] like Figures 1-3As shown, the welding assembly includes a first guide rod 6, a motor 7, a lead screw 8, an electric slide 9, a welding gun 10, a double-headed cylinder 11, and a clamping block 12. Two first guide rods 6 are bolted side-by-side to the front of the electric slide plate 4. The motor 7, electrically connected to the controller 26, is bolted to the upper front of the electric slide plate 4, with its output shaft facing downwards. The two first guide rods 6 are located on the left and right sides of the motor 7, respectively. The upper end of the lead screw 8 is fixedly connected to the output shaft of the motor 7 via a coupling. The electric slide 9 is slidably positioned between the two first guide rods 6. The welding gun 10 is bolted to the front of the electric slide table 9, and the double-headed cylinder 11 is bolted to the lower part of the welding gun 10. The two telescopic ends on the welding gun 10 extend forward and backward respectively, and a clamping block 12 is welded on each telescopic end. The welding gun 10 and the double-headed cylinder 11 are both electrically connected to the controller 26. The contact surface of each clamping block 12 is designed as an arc structure. This arc structure can fit tightly with the circular surface of the upper end of the stud, evenly distribute the clamping force, and achieve stable clamping of the stud.

[0024] like Figure 1 , Figure 6 and Figure 7As shown, the clamping assembly includes clamping plates 18, second guide rods 19, springs 20, wedge blocks 21, cam followers 22, guide bars 23, guide blocks 24, and screws 25. Two clamping plates 18 are slidably arranged on the loading platform 17, facing each other. Four second guide rods 19 are welded to the loading platform 17 along a rectangular direction. Each clamping plate 18 is slidably connected to two longitudinally aligned second guide rods 19, allowing the clamping plates 18 to slide smoothly under the guidance of the second guide rods 19. Each spring 20 is sleeved on the outside of each second guide rod 19, with its inner and outer ends connected to the loading platform 17 and the corresponding clamping plate, respectively. 18 is fixedly connected to provide a restoring force for the clamping plate 18. Each wedge block 21 is welded to the outward side of each clamping plate 18. Two guide bars 23 are arranged side by side and slidably disposed at the lower part of the upright 2. Each guide bar 23 has an inclined surface and a straight surface. The inward inclined surface of the front end of the guide bar 23 corresponds to the outer inclined surface of the adjacent wedge block 21, and the inward straight surface is in close contact with the outward side of the corresponding clamping plate 18, so that the guide bar 23 compresses the clamping plate 18 in the initial state, so that the spring 20 is already in a slightly compressed state in the initial state. Two screws 25 are arranged side by side with threads at the lower part of the upright 2, and are respectively connected to the two guide bars 23. The rear end is rotatably connected, and each screw 25 extends to the outer end of the upright 2 and is equipped with two circular blocks. The inner circular block is in close contact with the surface of the upright 2, which limits the range of movement of the screw 25, so that the screw 25 can only move in one direction (i.e., to the right) in the initial state. The outer circular block serves as a knob for the screw 25, providing a point of leverage for the operator's hand, making it easy for the operator to rotate the screw 25 and achieve precise adjustment of the position of the guide bar 23. Each cam follower 22 is rotatably set at the sharp corner of the front end of each wedge block 21. A certain distance is reserved between the guide bar 23 and the adjacent inclined surfaces of the wedge block 21. The spacing serves as the accommodating space for the cam follower 22, allowing the cam follower 22 to be precisely positioned between the guide bar 23 and the wedge block 21. The rolling surface of the cam follower 22 is tightly attached to the inward-facing inclined surface of the front end of the adjacent guide bar 23, achieving precise rolling cooperation between the two. This ensures the stability and accuracy of the relative movement between the guide bar 23 and the wedge block 21. The two guide blocks 24 are welded to the lower part of the stand 2 in a horizontal row. The guide bar 23 and the guide block 24 slide in corresponding positions, thus providing a stable support and guiding structure for the guide bar 23 on the stand 2 and improving the smoothness of the guide bar 23 during sliding.

[0025] When this equipment is needed, the operator first inputs the pre-set welding program into the controller 26, then places an appropriate number of studs on the conveying area of ​​the conveyor 13, then places the assembled steel structure to be welded on the loading platform 17, and then screws the nut 151 upwards in sequence to disengage it from the limit plate 14, unlocking the limit rod 15. Then, according to the upper end size of the stud, the limit rod 15 is moved inwards to the appropriate position of the slide 141. After that, the nut 151 is screwed downwards to re-engage with the limit plate 14, locking the limit rod 15. This ensures that the cylindrical surfaces of the two longitudinally aligned limit rods 15 maintain an appropriate distance, meeting the diameter requirements of the upper end of studs of different sizes, and realizing the limiting requirements of studs of different sizes.

[0026] Next, rotate the screw 25 outward to move the guide bar 23 outward to a suitable position so that the straight surface of the guide bar 23 no longer presses against the clamping plate 18, the spring 20 fully returns to its original state, and pushes the clamping plate 18 outward to prepare for the subsequent clamping of the steel structure.

[0027] After waiting for a period of time to ensure that all preparations are in place, the controller 26 issues a command to start the conveyor 13, which begins to transport the studs to the left. When the studs pass the two longitudinally aligned limit bars 15 during the leftward movement, they briefly pause for a moment through sliding contact with the cylindrical surface of the limit bar 15 to ensure that each stud maintains an appropriate spacing. When the first stud from left to right is transported to the leftmost end between the two limit plates 14, the controller 26 controls the conveyor 13 to stop running.

[0028] Subsequently, the controller 26 activates the first electric slide rail 3, controlling the electric slide plate 4 to slide to the right until the welding gun 10 is aligned with the first stud from left to right. At this time, the controller 26 activates the motor 7, controlling its output shaft to drive the lead screw 8 to rotate clockwise. Driven by the lead screw 8, the electric slide table 9 moves all the components on it downward until a specific part of the welding gun 10 (similar to the nailing position of a nailing machine) accommodates the upper end of the first stud. After the upper end of the stud extends into the corresponding part of the welding gun 10, the controller 26 activates the double-headed cylinder 11, controlling its two telescopic ends to retract synchronously, driving the two clamping blocks 12 to move inward to clamp the upper end of the first stud, thus firmly fixing the stud on the welding gun 10. Afterward, the controller 26 controls the output shaft of the motor 7 to drive the lead screw 8 to rotate counterclockwise. Driven by the lead screw 8, the electric slide table 9 moves all the components on it upward until the welding gun 10 returns to its initial height.

[0029] After ensuring that the welding gun 10 is fixed with a stud, the controller 26 controls the electric slide plate 4 to move to the left to a suitable position, and at the same time starts the second electric slide rail 16 to control the loading platform 17 to move the steel structure backward to a suitable position until the welding gun 10 is aligned with the position of the steel structure to be welded.

[0030] During the rearward movement of the loading platform 17, the wedge block 21 moves backward along the inclined surface of the guide bar 23 and comes into contact with the straight surface of the guide bar 23 when it leaves the inclined surface. It is squeezed inward by the straight surface and moves inward. The clamping plate 18 moves inward together with the wedge block 21, approaches and clamps the steel structure. As the clamping plate 18 moves inward, the spring 20 is stretched.

[0031] After clamping the steel structure, the controller 26 controls the output shaft of the motor 7 to drive the lead screw 8 to rotate clockwise, thereby driving the electric slide table 9 to move all the components set on it downwards. At the same time, the welding gun 10 is started, so that when the welding gun 10 moves down to contact the position of the steel structure to be welded, it welds the studs onto the steel structure.

[0032] After the welding operation is completed, the controller 26 shuts off the welding gun 10 and controls the output shaft of the motor 7 to drive the lead screw 8 to rotate counterclockwise, thereby driving the electric slide table 9 to move all the components on it upwards. At the same time, it controls the loading platform 17 to move the steel structure forward. During this process, the wedge block 21 moves forward along the straight surface of the guide bar 23 and contacts the inclined surface of the guide bar 23 when it leaves the straight surface. It is no longer squeezed by the straight surface, and the spring 20 immediately returns to its original state, pushing the clamping plate 18 to move the wedge block 21 outwards together, detaching from and releasing the steel structure. At this time, the welded steel structure is removed from the loading platform 17. The above operation steps are repeated to continue welding the next steel structure.

[0033] Under the unified control of the controller 26, the entire equipment continuously repeats the above feeding, steel structure clamping and welding steps, realizing automated continuous feeding and welding of steel structure studs, which greatly improves production efficiency and reduces the intensity of manual monitoring and labor.
