Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, and in particular to an automated intelligent equipment for processing and welding closed stirrups on construction sites. Background Technology

[0002] Welded closed stirrups are stirrup structures formed by welding the joints together. They have a good restraining effect. However, there are many problems in the actual production and processing of welded closed stirrups. First, the existing technology mostly uses manual welding, and the welding quality is completely controlled by humans, making it difficult to control the quality of the produced welded closed stirrups. Secondly, flash butt welding is the mainstream method for welding closed stirrups. However, during the bending and forming process of closed stirrups, due to the ductility of the steel bars themselves and the influence of the cutting operation of the bending mechanism, the two ends of the closed stirrup to be welded are generally misaligned, that is, the two ends to be welded are not on the same axis. This misalignment will greatly reduce the welding effect, resulting in poor connection between the two welded ends, and the closed stirrup will not be able to effectively play its restraining role. In the existing technology, the position correction operation of the two ends to be welded is mostly performed by vertical limiting clamping, that is, limiting clamping from the Y-axis direction. However, the Y-axis direction correction method can only make the two ends to be welded on the same horizontal line in the X-axis plane, but the two ends to be welded are still misaligned in the Z-axis plane. Therefore, it is impossible to achieve effective position correction operation of the two ends to be welded. Meanwhile, in flash butt welding, to ensure welding quality and tightness, the two ends to be welded must be in close contact. Therefore, the two ends to be welded must be centered and squeezed. However, the existing centered method is to first limit and fix the two ends to be welded by a vertical limiting mechanism, and then use an additional centered mechanism to push the vertical limiting mechanism holding the two ends to be welded to perform a horizontal centered operation. In the above process, the vertical limiting and horizontal centered operations must be performed separately, and both require at least 2 to 4 power sources (such as cylinders) to drive them. This segmented operation not only increases the purchase and maintenance costs of equipment, but also significantly reduces welding efficiency due to the multiple steps. Moreover, the repeated switching of power sources and movement of mechanisms can easily generate cumulative errors, affecting welding accuracy and making it difficult to guarantee the stability of welding quality. Summary of the Invention

[0003] In view of the problems existing in the prior art, the present invention proposes an automated intelligent equipment for processing and welding closed stirrups on construction sites to solve such problems.

[0010] As a preferred embodiment of the present invention for an automated intelligent equipment for processing and welding closed stirrups at construction sites, the pulling component includes a connecting rod inserted into the outer end of the pressure head, with the lower end of the connecting rod extending into the mounting plate, multiple sets of guide grooves equally distributed on the connecting rod, the upper end of the guide groove being a rectangular structure and the lower end being a spiral arc structure, a turntable disposed at the lower end of the connecting rod, and two sets of arc grooves equally distributed on the turntable, with the inner end of the centering component extending into the arc groove.

[0011] As a preferred embodiment of the present invention for an automated intelligent equipment for processing and welding closed stirrups on construction sites, the centering component includes a connecting component located in a fixed groove, with the inner end of the connecting component connected to the arc-shaped groove, and a pressing component and a clamping component disposed below the outer end of the connecting component, both of which are located below the mounting plate, and a pad for increasing friction is provided at the bottom of the pressing component.

[0012] As a preferred embodiment of the present invention for an automated intelligent equipment for processing and welding closed stirrups on construction sites, the connecting component includes a slide rod located in a fixed groove, a fixed shaft disposed above the inner end of the slide rod and extending into the arc-shaped groove, and a pressure plate disposed above the outer end of the slide rod.

[0013] As a preferred embodiment of the present invention for an automated intelligent equipment for processing and welding closed stirrups at construction sites, the clamping assembly includes a mounting frame connected to the outside of the pressing assembly. The mounting frame has a mounting groove, and two sets of clamping members are symmetrically arranged on both sides of the mounting groove. A rectangular rod is horizontally mounted inside the mounting groove, and a triangular plate of an isosceles triangle structure is vertically slidably connected to the rectangular rod.

[0014] The beneficial effects of this invention are as follows: By setting up a correction unit and a centering unit to cooperate in performing flash butt welding on the stirrup body, the centering unit moves closer to the correction unit along the Y-axis, which can realize the position correction of the two ends of the stirrup body to be welded in the X-axis direction. At the same time, during the position correction in the X-axis direction, the correction unit itself can also correct the position of the two ends of the stirrup body to be welded in the Z-axis direction, thereby making the two welding ends of the stirrup body on the same axis. Through the multi-axis linkage position correction method, the accuracy and firmness of the welding are effectively guaranteed. Compared with the traditional single-direction correction, the welding efficiency is greatly improved, the error of manual adjustment is reduced, and the probability of welding defects is reduced. Simultaneously, after the centering unit moves closer to the straightening unit and achieves the straightening work of the stirrup body to be welded in the X-axis direction, the centering unit will simultaneously push the two ends to be welded from both sides to center them, thereby realizing the flash welding operation of the two ends to be welded. In summary, the present invention can combine the position correction operation and centering operation of the straightening unit and the centering unit, effectively simplifying the steps of the welding work and significantly improving the efficiency of the welding work. At the same time, both only require a single power source to drive the centering unit to move, which can realize the synchronous start of the correction unit and the centering unit to perform position correction and centering operations. The integrated drive design greatly reduces the energy consumption cost of the equipment and also reduces the error accumulation that may occur when multiple power sources work together, thereby effectively improving the quality of welding work and the efficiency of production work.

Detailed Implementation

[0027] To make the above-mentioned objectives, features and advantages of the present invention more readily understood, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0029] Reference Figures 1 to 11 This invention includes an automated intelligent device for processing and welding closed stirrups at a construction site. It comprises a straightening unit 1, a centering unit 2, and an intelligent control module. The intelligent control module is electrically connected to the straightening unit 1 and the centering unit 2, and can control their start and stop. There are two sets of straightening units 1, symmetrically arranged. Each set of straightening units 1 has a welding block 17 connected to its inner side. The intelligent control module uses existing technology and can control the circuit connection and disconnection of the welding block 17, as well as the extension and retraction of the cylinder 31 on the centering unit 2. The two sets of welding blocks 17 are respectively connected to the positive and negative terminals of the circuit. The two sets are connected by overlapping the stirrup body 10 to achieve circuit connection, thereby enabling flash butt welding. Reference Figure 7The centering unit 2 includes a vertically arranged driving component 3, a pulling component 4 inserted into the inner side of the driving component 3, a support spring 5 sleeved on the pulling component 4, and two sets of centering components 6 symmetrically arranged on both sides of the driving component 3. The inner ends of the centering components 6 are connected to the lower ends of the pulling component 4. The driving component 3 is used to push the pulling component 4 to move vertically, thereby pushing the two centering components 6 on both sides closer to or further away from the correction unit 1. During the downward movement of the two sets of centering components 6, the two ends to be welded of the stirrup body 10 can be aligned and pulled.

[0030] Reference Figure 4 The drive disk 13 has two sets of drive slots 131, and the lower end of the correction component 15 is inserted into the drive slot 131. The drive disk 13 has a slot 132 at its center, and the upper end of the drive component 14 is inserted into the slot 132. The drive slot 131 has an arc-shaped structure, and the arc-shaped structure is tilted outward from the center of the drive disk 13. The slot 132, through its matching structure with the drive component 14, can achieve mutual circumferential positioning between the drive disk 13 and the drive component 14.

[0031] Reference Figure 4 The drive assembly 14 includes a shaft 141 inserted into a slot 132, a rotating shaft 142 with a cylindrical structure disposed at the lower end of the shaft 141, two sets of connecting shafts 143 symmetrically disposed on the outer wall of the rotating shaft 142, the connecting shafts 143 extending outward to the inner wall of the fixed seat 16, and two sets of limiting plates 144 respectively disposed at the top end of the shaft 141 and the lower end of the rotating shaft 142. The shaft 141 inserted into the slot 132 enables the drive disk 13 and the drive assembly 14 to rotate synchronously, but they do not interfere with each other in the vertical direction. Therefore, the shaft 141 can freely extend and retract in the vertical direction within the drive disk 13. The connecting shafts 143 on both sides of the outer end of the rotating shaft 142 connect the drive assembly 14 and the fixed seat 16 together, so that the movement of the drive assembly 14 is restricted by the fixed seat 16. The lower end of the rotating shaft 142 passes through the fixed seat 16.

[0032] Reference Figure 4The lower end of the straightening component 15 is provided with a slider 151 that is slidably connected in the limiting groove 12. Multiple sets of rollers 152 are equally distributed on the inner side of the straightening component 15, and the rollers 152 are rotatably connected to the inner side of the straightening component 15. The lower end of the slider 151 is provided with an extension shaft 153, and the extension shaft 153 extends downward into the drive groove 131. The straightening component 15 is limited by the limiting groove 12 through the slider 151, so it can only slide within the limiting groove 12. At the same time, the cross-section of the slider 151 and the limiting groove 12 are both convex structures, so the straightening component 15 will not detach from the base 11 in the vertical direction. The rollers 152 that are rotatably connected to the inner side of the straightening component 15 can ensure that when the straightening component 15 is subjected to an inward clamping force, it does not hinder the lateral translation of the stirrup body 10. The extension shaft 153 extending into the drive groove 131 means that the straightening component 15 will be affected by the rotation of the drive disk 13.

[0033] Reference Figure 4 The fixed base 16 has a guide tube 161 at its axis. The guide tube 161 has guide grooves 162 with a helical angle structure evenly distributed on it. Two sets of connecting shafts 143 extend and slide within the two sets of guide grooves 162 respectively. A bottom spring 163 is located at the lower end of the fixed base 16, and the top of the bottom spring 163 abuts against the limiting plate 144 at the lower end of the rotating shaft 142. The fixed base 16 is fixedly connected to the base 11. The guide tube 161 located in the fixed base 16 is also fixedly connected to the base 11. The helical angle guide grooves 162 can limit the movement direction of the connecting shafts 143, so that the connecting shafts 143 can change their position in the circumferential direction along their helical angle.

[0034] Combination Figure 2 , Figure 5 and Figure 6 During use, the two ends of the stirrup body 10 to be welded are placed on the two sets of correction units 1 respectively. At this time, the weight of the stirrup body 10 itself presses the drive component 14 to contract slightly downward, so that the stirrup body 10 is initially attached to the correction unit 1. As the centering unit 2 moves downward, the two sets of centering components 6 set on the centering unit 2 will press the upper ends of the two ends to be welded, and thus apply downward pressure to them. At this time, the centering component 6 moving downward cooperates with the correction unit 1 to realize the vertical position correction operation of the ends to be welded of the stirrup body 10, so that the two ends to be welded of the stirrup body 10 are at the same height in the horizontal direction, that is, to realize the position correction of the two ends to be welded of the stirrup body 10 in the X-axis direction. During the process of the centering components 6 at both ends of the centering unit 2 pressing down on the welding end of the stirrup body 10, the drive assembly 14 will be simultaneously subjected to downward pressure. The end of the downward-moving drive assembly 14 will be limited by the guide groove 162 through the connecting shaft 143. At this time, the guide groove 162 will guide the drive assembly 14 to rotate in a circumferential direction through its own spiral structure in cooperation with the connecting shaft 143. The rotating drive assembly 14 will drive the drive disk 13 to rotate through the cooperation of the insertion shaft 141 and the slot 132. At this time, the rotating drive disk 13 will push the extension shaft 153 simultaneously through the drive grooves 131 on both sides. At this time, the extension shaft 153 will drive the straightening assembly 15 to slide along the limiting groove 12. At this time, the two sets of straightening assemblies 15 are synchronized. Driven by the drive disc 13, the two sets of straightening components 15 clamp the front and rear sides of the stirrup body 10 inward. Since the two sets of straightening components 15 move synchronously, they clamp inward in a synchronized and centered manner, causing the weldable end of the stirrup body 10 located between them to move closer to the center of the two. This achieves the positional correction of the weldable end of the stirrup body 10 from the Z-axis direction. In summary, by using a multi-axis linkage positional correction method, it is possible to effectively ensure that the two weldable ends of the stirrup body 10 are on the same axis, thereby ensuring the accuracy and firmness of the welding. Compared with the traditional single-direction correction, it greatly improves welding efficiency, reduces errors from manual adjustment, and lowers the probability of welding defects.

[0035] Reference Figure 7 The driving component 3 includes a vertically arranged cylinder 31, a telescopic rod 32 located at the axis of the cylinder 31, a triangular mounting plate 33 with its top end inserted into the telescopic rod 32, two sets of fixing grooves 34 symmetrically arranged at the base of the triangular structure of the mounting plate 33, with the upper ends of two sets of centering components 6 extending into the two sets of fixing grooves 34 respectively, a pressure head 35 located at the top of the cylinder 31, with the upper end of the pulling component 4 inserted into the outer end of the pressure head 35, and multiple sets of balls 36 equally distributed on the inner wall of the outer end of the pressure head 35, with the balls 36 extending into the inner wall of the pulling component 4. The cylinder 31 is electrically connected to and controlled by the intelligent control module, and the pulling component 4... The entire assembly is held between the pressure head 35 and the mounting plate 33 by the elastic support of the support spring 5. At the same time, the mounting plate 33 is rotatably connected to the lower end of the pulling component 4, meaning that the mounting plate 33 can move synchronously with the lower end of the pulling component 4. The mounting plate 33 is slidably connected to the cylinder 31 in the vertical direction, so the telescopic rod 32 can slide vertically on the mounting plate 33. The fixing groove 34 is used to limit the movement direction and range of the connecting assembly 7. One side of the pressure head 35 extends outward and is fixedly connected to the telescopic rod 32, so its height position changes accordingly with the extension and retraction of the telescopic rod 32. The upper end of the pulling component 4 is inserted into the pressure head 35.

[0036] Reference Figure 7 The pulling component 4 includes a connecting rod 41 inserted into the outer end of the pressure head 35, with the lower end of the connecting rod 41 extending into the mounting plate 33. Multiple sets of guide grooves 42 are equally spaced on the connecting rod 41, with the upper end of each guide groove 42 being rectangular and the lower end being a spiral arc shape. A turntable 43 is located at the lower end of the connecting rod 41, and two sets of arc-shaped grooves 44 are equally spaced on the turntable 43. The inner end of the centering component 6 extends into the arc-shaped groove 44. The ball bearing 36 extends and fits within the guide groove 42. When the pulling component 4 cannot move vertically, the ball bearing... During the downward movement, the ball bearing 36 will be driven to rotate by the spiral structure of the guide groove 42. The rectangular structure at the upper end of the guide groove 42 causes the ball bearing 36 to initially move a certain distance downward along the connecting rod 41. Then, the spiral groove at the lower end of the guide groove 42 will drive the connecting rod 41 to rotate. The arc groove 44 is an arc structure, and the arc structure extends outward from the center of the turntable 43. At the same time, during the rotation of the pulling component 4, the centering component 6 will be driven to move along the fixed groove 34 through the arc groove 44.

[0037] Reference Figure 9 The centering component 6 includes a connecting component 7 located within the mounting plate 33, with the inner end of the connecting component 7 connected to the arc-shaped groove 44, and a pressing component 8 and a clamping component 9 disposed below the outer end of the connecting component 7. Both the pressing component 8 and the clamping component 9 are located below the mounting plate 33. A pad 81 for increasing friction is provided at the bottom of the pressing component 8. The pad 81 can be made of a material that is soft and can increase the friction between it and the stirrup body 10. The clamping component 9 is used to clamp the stirrup body 10, and the connecting component 7 is used to pull the connecting component 7 to move as a whole during the rotation of the pulling component 4.

[0038] Reference Figure 9 The connecting component 7 includes a slide rod 71 located in the fixed groove 34, a fixed shaft 72 disposed above the inner end of the slide rod 71 and extending into the arc-shaped groove 44, and a pressure plate 73 disposed above the outer end of the slide rod 71. The end of the connecting component 7 is fixedly connected to the connection between the pressing component 8 and the clamping component 9. The slide rod 71 is limited by the fixed groove 34 and can only move within the fixed groove 34. The connecting component 7 is driven by the pulling component 4 through the connection between the fixed shaft 72 and the arc-shaped groove 44. The pressure plate 73 is used to keep the connecting component 7 always within the fixed groove 34.

[0039] Reference Figure 9The clamping assembly 9 includes a mounting bracket 91 connected to the outside of the pressing assembly 8, a mounting groove 92 opened on the mounting bracket 91, two sets of clamping members 93 symmetrically arranged on both sides of the mounting groove 92, a rectangular rod 94 horizontally mounted in the mounting groove 92, a triangular plate 95 with an isosceles triangular structure and vertically slidably connected to the rectangular rod 94, with the two isosceles sides of the triangular plate 95 respectively abutting the top of the two sets of clamping members 93, and a reset assembly 96 set at the top of the inside of the mounting groove 92, with the lower end of the reset assembly 96 abutting the outer side of the top of the two sets of clamping members 93. A rectangular groove 951 matching the rectangular rod 94 is opened at the center of the triangular plate 95. The triangular plate 95 is connected to the rectangular rod 94 through the rectangular groove 951 and can only move vertically under the limitation of the rectangular rod 94. Furthermore, refer to Figure 10 The triangle 95 can push the two sets of clamping parts 93 on both sides through its two inclined sides. When the height of the triangle 95 changes, the contact position between the two inclined sides of the triangle 95 and the clamping parts 93 will change, thereby pushing the top of the clamping parts 93 outward at an angle, so that the position of the clamping parts 93 will be adjusted. Reference Figure 10 The clamping member 93 includes an arc-shaped clamping plate 931, mounting shafts 932 connected to both sides of the clamping plate 931 and extending outward into the mounting frame 91, a clearance groove 933 opened in the clamping plate 931, and a triangular plate 95 passing through the clearance groove 933 vertically, a roller 934 rotatably connected to the top of the clamping plate 931 and abutting against the isosceles side of the triangular plate 95, and a pad 935 disposed on the inner side of the lower end of the clamping plate 931. The clamping member 93 as a whole can rotate about the mounting shaft 932 as the axis. The clearance groove 933 is used to make way for the triangular plate 95, and the pad 935 is used to increase the friction between the clamping member 931 and the stirrup body 10, so as to ensure that the stirrup body 10 can be accurately pulled for centering operation. Reference Figure 10 The reset assembly 96 includes a vertically arranged arc-shaped frame 961, a plug rod 962 located at the lower end of the arc-shaped frame 961 with an opening facing downwards, a storage block 963 located above the mounting bracket 91 with the upper end of the arc-shaped frame 961 extending into the storage block 963, and a reset spring 964 located in the storage block 963 with its lower end abutting against the arc-shaped frame 961. The reset spring 964 can push the plug rod 962 downwards through its own elasticity, and the downwardly pushed plug rod 962 can push and reset the two sets of clamping members 93, so that the two sets of clamping members 93 are in an open state when idle.

[0040] Combination Figure 2 and Figure 11As shown in the figure, during the use of the centering unit 2, the cylinder 31 drives the pulling component 4 and the two sets of centering components 6 to move downward and approach the pulling component 4 via the telescopic rod 32, mounting plate 33, and pressure head 35. During the downward movement of the two sets of centering components 6, the triangular plate 95 will first contact the stirrup body 10 initially fixed on the straightening unit 1. As the centering component 6 continues to move downward, the triangular plate 95 will eventually move upward under the action of the opposite force. The moving triangular plate 95 will move upward through the inclined planes on both sides. While pushing the two sets of clamping members 93, the clamping members 93 rotate inward around the mounting shaft 932 under the action of the pushing force. The two sets of clamping members 93 rotate inward synchronously and eventually hug and clamp the two sides of the stirrup body 10 to be welded. As the driving component 3 drives the centering component 6 to move downward, the connection between the clamping assembly 9 and the stirrup body 10 through the two sets of clamping members 93 will become closer. Finally, the two sets of clamping assemblies 9 will firmly hug and clamp the two ends of the stirrup body 10 to be welded. After the two sets of clamping components 9 are firmly clamped onto the stirrup body 10, the centering component 6 and the straightening unit 1 will be in a fully pressed state. At this time, the reverse force applied by the straightening unit 1 to the centering component 6 is equal to the elastic state of the support spring 5, so that the mounting plate 33 and the pulling component 4 will be kept at a fixed height. At this time, the cylinder 31 still drives the telescopic rod 32 to retract. At this time, the pressure head 35 at the top of the telescopic rod 32 will slide downward along the connecting rod 41. The downward sliding pressure head 35 will overcome the elasticity of the support spring 5 and retract it. At the same time, the downward moving pressure head 35 will push the pulling component 4 to rotate through the helical angle cooperation of the ball 36 and the guide groove 42. The rotating pulling component 4 will pull the two sets of connecting components 7 to move in opposite directions within the fixed groove 34 through the arc groove 44. The moving connecting component 7 will drive the clamping components 9 of the two sets of clamping and limiting stirrup bodies 10 to be welded to move relative to each other, so that the two ends to be welded are aligned and abutted together. After the centering unit 2 moves closer to the straightening unit 1 and straightens the ends to be welded of the stirrup body 10 in the X-axis direction, the two ends to be welded are pushed to be aligned from both sides at the same time. The straightening operation and the centering operation are combined, which simplifies the welding operation and thus significantly improves the efficiency of the welding operation. At the same time, both only need to be driven by a single power source cylinder 31 to realize the synchronous start of the straightening unit 1 and the centering unit 2 to perform position correction and centering operations, which greatly reduces the energy consumption cost of the equipment and reduces the possible error accumulation when multiple power sources work together, thereby effectively improving the quality of the welding operation and the efficiency of the production operation.
