Description

Technical Field

[0001] The invention belongs to the technical field of welding, and in particular relates to a welding displacement device for a traffic sign pole. Background Art

[0002] Traffic sign poles are a vital component of road traffic infrastructure, and their welding quality directly impacts their service life and safety. Welding is a critical process in the production of traffic sign poles. Currently, most traffic sign poles utilize a hollow pole body and a base. This welding process requires not only a secure welding of the hollow pole to the base, but also the welding of the reinforcing ribs between them to enhance the overall structural stability of the traffic sign pole.

[0003] During welding operations, the conventional operation is to place the welding gun opposite to the weld. When welding the marker pole and the base, the existing position change device can drive the two to rotate to complete the welding. However, when welding the reinforcement between the two, since the position between the reinforcement and the marker pole to be welded is in a vertical state, the welding gun is also in a vertical state at this time, which causes the welding gun and the weld to be welded to be in a parallel state (such as Figure 1 (As shown). This parallel state prevents the welding gun from directly contacting the junction between the rib and the signpost, making conventional welding impossible. Operators are forced to use a complex process to adjust the relative angles and positions of the traffic signpost, base, and ribs. This is not only time-consuming, but the frequent adjustments can easily cause already positioned components to shift, seriously affecting welding accuracy.

[0004] In view of this, the present invention is proposed. Summary of the Invention

A cylindrical inner cavity is opened inside the sleeve, and a push rod is movably inserted on the sleeve. The length of the push rod is greater than the height of the sleeve. A ball sleeve is installed on the top of the push rod, and a rolling ball is embedded in the ball sleeve. The rolling ball is attached to the lower surface of the chuck.

[0015] As a preferred embodiment of the present invention, a baffle is slidingly provided inside the sleeve, the baffle is tightly fitted with the cylindrical inner cavity, and the top of the baffle is connected to the push rod, and a positioning spring is installed at the bottom of the baffle, the positioning spring is fitted on the end face of the sleeve, and the compression direction of the positioning spring and the moving direction of the push rod are on the same straight line.

[0039] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0040] Example 1:

[0041] like Figures 1 to 9 As shown, a welding displacement device for a traffic sign pole includes a chuck 1, an adapted base 4, a traffic pole 5, and a reinforcing rib 6 located therebetween.

[0042] A shifting assembly is installed at the bottom of the chuck 1. The shifting assembly includes a slide 2. A rotating shaft 223 is swingably mounted on the slide 2 and connected to the chuck 1. A pair of rotating disks 3 with opposite rotations are symmetrically mounted on the slide 2.

[0043] Each turntable 3 is equipped with a first half gear 32 corresponding to the central angle of the adjacent reinforcing rib 6 and a second half gear 322 corresponding to the thickness of the reinforcing rib 6, and the first half gear 32 and the second half gear 322 are engaged with the gear ring 321 installed at the bottom of the chuck 1, and the turntable 3 is used to drive the chuck 1 to change position; compared with the traditional welding device that requires manual adjustment of the position of components, this design drives the chuck to rotate through gear engagement, which can accurately and efficiently drive the various components of the traffic sign pole to rotate, avoid errors and inefficiency in manual operation, and significantly improve the efficiency of the welding preparation stage.

[0044] Each turntable 3 is equipped with staggered push rods 331, and a flap 332 is mounted at the center of the swing of the rotating shaft 223. After the ring gear 321 stops engaging, the push rods 331 squeeze the flap 332, causing the chuck 1 to deflect, creating an angle between the vertical direction of the reinforcement rib 6 and the welding gun. After the ring gear 321 reengages, the push rods 331 and flap 332 separate. This innovative structure specifically solves the problem of the prior art that the reinforcement weld seam cannot be welded when it is parallel to the welding gun. The automated deflection action eliminates the need for repeated manual angle adjustment, significantly saving welding time and improving welding efficiency.

[0045] like Figures 1 to 9 As shown in the figure, in a specific embodiment, a clamping groove 11 is formed inside the chuck 1, and the base 4 is placed in the clamping groove 11, and the base 4 and the clamping groove 11 are in a concentric state. A locking bolt 111 is rotatably installed on the side wall of the chuck 1. The end of the locking bolt 111 is placed inside the clamping groove 11 and tightly fits against the side wall of the base 4. This installation method ensures that the base is firmly fixed, avoids welding deviation caused by base shaking during welding, and ensures welding accuracy, which is superior to traditional unstable installation methods.

[0046] like Figures 1 to 9As shown, the bottom of the chuck 1 is provided with a notch 124, and a rod 123 is movably inserted into the side wall of the notch 124. A clamping plate 12 is mounted on the end of the rod 123. The clamping plate 12 and the inner side wall of the traffic pole 5 are pressed against each other. A threaded rod 121 is rotatably mounted on the clamping plate 12. The threaded rod 121 is rotatably connected to the chuck 1, and a knob 122 is fixedly mounted on the end of the threaded rod 121. This design can firmly fix the traffic pole 5, prevent the traffic pole 5 from shifting during the welding process, ensure the accuracy of the welding position, and guarantee the stability and reliability of the welding process.

[0047] Example 2:

[0048] The difference between Example 1 and this example is that: Figures 1 to 9 As shown, a slide rail 21 is provided at the bottom of the slide 2, and the slide rail 21 is slidably connected to the workbench of the welding equipment. A positioning hole 211 is provided on the slide 2, and the positioning hole 211 is connected to the slide rail 21. A bolt for locking the position of the slide rail 21 is installed inside the positioning hole 211. A soft cover 24 is installed on the slide 2, and the soft cover 24 is connected to the lower surface of the chuck 1. The cooperation between the slide rail 21 and the positioning hole 211 can flexibly adjust the position of the slide 2 according to different welding process requirements, achieve accurate positioning of the welding position, and expand the scope of application of the device. The provision of the soft cover 24 can effectively prevent sparks, spatter, etc. generated during the welding process from damaging the internal structure of the device, extending the service life of the device, while also reducing cleaning work and keeping the working environment clean.

[0049] like Figures 1 to 9 As shown, in a specific embodiment, 5. A mounting seat 22 is mounted on the slide 2, and a synchronous shaft 221 is rotatably mounted on the mounting seat 22. A rotating shaft 223 is fixedly mounted on the synchronous shaft 221. A cover plate 224 is rotatably mounted on the end of the rotating shaft 223. The cover plate 224 covers the bottom of the chuck 1. A torsion spring 222 is sleeved on the synchronous shaft 221. One end of the torsion spring 222 is clamped on the mounting seat 22, and the other end is clamped on the rotating shaft 223. The function of the torsion spring 222 enables the chuck 1 to automatically reset after completing the deflection welding of a specific angle, without the need for additional reset operations, thereby simplifying the workflow and improving welding efficiency. The cover plate 224 protects the key components at the bottom of the chuck 1, preventing dust and debris from entering and affecting the performance of the device.

[0050] like Figures 1 to 9As shown, a pair of mutually symmetrical sleeves 23 are mounted on the slide 2, and the pair of sleeves 23 are located in the plane of the swing of the rotating shaft 223. A cylindrical inner cavity is defined within the sleeve 23, and a push rod 231 is movably inserted into the sleeve 23. The length of the push rod 231 is greater than the height of the sleeve 23. A ball sleeve is mounted on the top of the push rod 231, and a rolling ball 232 is embedded in the ball sleeve. The rolling ball 232 is attached to the lower surface of the chuck 1. A baffle 233 is slidably mounted inside the sleeve 23. The baffle 233 fits tightly with the cylindrical inner cavity, and the top of the baffle 233 is connected to the push rod 231. A positioning spring 234 is mounted on the bottom of the baffle 233. The positioning spring 234 is attached to the end face of the sleeve 23, and the compression direction of the positioning spring 234 is aligned with the movement direction of the push rod 231. The combination of the push rod 231 and the ball 232, as well as the elastic support of the positioning spring 234, can provide stable support to the chuck 1 in real time during the displacement of the chuck 1, effectively offset the shaking caused by the rotation and deflection of the chuck 1, and ensure the stability of the position of the traffic sign pole during welding, thereby improving the welding quality and reducing welding defects.

[0051] Example 3:

[0052] The difference between Example 2 and this example is that: Figures 1 to 9 As shown, a drive shaft 312 is mounted at the rotation center of each turntable 3. The height of the drive shaft 312 is lower than the height of the swing center axis of the rotation axis 223. A drive motor 31 is mounted at the end of each drive shaft 312. The drive motor 31 is located above the slide 2, and the two drive motors 31 are used to drive the two turntables 3 to rotate in opposite directions. The design of dual drive motors 31 provides stable and powerful power for the rotation of the turntables 3, ensuring that the chuck 1 can be quickly and smoothly adjusted. Compared with a single drive method, this greatly shortens the welding adjustment time and improves the efficiency of the overall welding operation.

[0053] like Figures 1 to 9 As shown, in a specific embodiment, a positioning bracket 311 is mounted on the housing of the drive motor 31. The positioning bracket 311 is L-shaped, with the distal end of the positioning bracket 311 abutting against the side wall of the slide 2. A positioning plate 313 is welded to the outer wall of the positioning bracket 311, abutting against the side wall of the slide 2, and a positioning bolt is screwed onto the positioning plate 313, which is rotatably connected to the side wall of the slide 2. This mounting method makes the fixing of the drive motor 31 more secure and reliable, reduces the impact of motor vibration on the overall stability of the device, ensures the long-term stable operation of the drive system, and reduces the probability of equipment failure.

[0054] like Figures 1 to 9As shown, a side rod 33 is mounted on the side wall of the push rod 331. The side rod 33 is connected to the rotation center of the turntable 3, and the end of the side rod 33 is adapted to the side wall of the flap 332. The bottom of the slide 2 is provided with an arcuate groove 333 adapted to the push rod 331, and the rotation center of the flap 332 is connected to the synchronization shaft 221. The arcuate groove 333 guides the movement of the push rod 331, ensuring that the push rod 331 can accurately contact the flap 332 and drive its rotation, thereby achieving precise displacement of the chuck 1 and further improving the reliability and stability of the device operation.

[0055] The implementation principle of the welding displacement device for traffic sign poles of the present invention is as follows:

[0056] When using the welding positioner of the present invention to weld traffic sign poles, the base 4 is first placed in the clamping groove 11 inside the chuck 1. The locking bolts 111 on the side walls of the chuck 1 are tightened so that the end of the base 4 fits tightly against the side walls of the base 4, achieving a secure installation of the base 4. Next, the traffic pole 5 is placed in the chuck 1. By turning the knob 122 to drive the threaded rod 121, the clamping plate 12 moves along the insertion rod 123 and presses against the inner wall of the traffic pole 5, thereby fixing the traffic pole 5 to the chuck 1. At the same time, the reinforcing rib 6 is installed between the base 4 and the traffic pole 5, completing the assembly and positioning of the components before welding.

[0057] When the welding operation is initiated, the drive motors 31 begin operating, with the two drive motors 31 driving the two turntables 3 in opposite directions. The first and second half gears 322 on the turntables 3 mesh with the ring gear 321 at the bottom of the chuck 1, driving the chuck 1 to rotate about its central axis. This causes the base 4, the traffic pole 5, and the reinforcement rib 6 to rotate together, facilitating the welding of the annular weld between the base 4 and the traffic pole 5. This is similar to the operation of conventional rotational welding driven by a transposition device.

[0058] When welding the connection between the traffic pole 5 and the base 4, the engagement of the first half gear 32 and the ring gear 321 can drive the traffic pole 5 and the base 4 to rotate synchronously, changing the welding position so that the traffic pole 5 and the base 4 can be fully welded at that position.

[0059] After the first half gear 32 and the gear ring 321 are separated, the welding gun is moved to the connection between the reinforcement rib 6 and the traffic pole 5. However, the gap to be welded is parallel to the welding gun and cannot be welded directly.

[0060] At this time, as the turntable 3 continues to rotate, the side rod 33 and the push rod 331 on the turntable 3 eventually fit into the side wall of the flap 332. As the turntable 3 continues to squeeze, the flap 332 can eventually rotate around the synchronization axis 221, and the push rod 331 will eventually separate from the push rod 331. The movement trajectories of the two are as follows: Figure 9 shown.

[0061] When the flap 332 rotates, because the rotation center of the flap 332 is connected to the synchronization shaft 221, the torsion spring 222 sleeved on the synchronization shaft 221 has one end clamped to the mounting seat 22 and the other end clamped to the rotation shaft 223. Under the pressure of the push rod 331, the flap 332 drives the rotation shaft 223 to swing around its swing center, thereby deflecting the chuck 1, creating an angle between the vertical direction of the reinforcement rib 6 and the welding gun. In this way, the reinforcement rib weld, which was originally parallel to the welding gun, is now at a convenient welding angle, allowing the welding gun to smoothly contact the weld seam for welding.

[0062] During welding, the slide rail 21 at the bottom of the slide 2 is slidably connected to the welding equipment's workbench. The position of the slide 2 can be adjusted according to actual welding requirements, and the position of the slide rail 21 is locked by bolts in the positioning holes 211 to ensure the stability of the device during welding. A push rod 231 inside the sleeve 23 mounted on the slide 2, driven by a positioning spring 234, ensures that the ball 232 always adheres to the lower surface of the chuck 1, supporting and stabilizing the chuck 1, preventing it from shaking during displacement and further ensuring welding accuracy.

[0063] When the welding on one side of the reinforcement rib 6 is completed (the flap 332 and the push rod 331 are separated at this time, and the flap 332 is automatically reset under the action of the torsion spring 222, so that the chuck 1 becomes horizontal again), the turntable 3 continues to rotate, and the ring gear 321 re-engages with the second half gear 322, thereby driving the chuck 1 to continue to rotate a certain angle. At this time, the rotation distance is the width of the reinforcement rib 6, which makes it easier for the welding gun to weld the end face of the reinforcement rib 6 and the traffic pole 5.

[0064] After welding is completed, the second half gear 322 and the ring gear 321 are separated.

[0065] However, as the turntable 3 continues to rotate, the push rod 331 located on the other turntable 3 with the opposite rotation direction can re-contact the flap 332, and then drive the chuck 1 to rotate in the opposite direction by a certain angle, so that the weld at the other end of the reinforcement rib 6 can rotate in the opposite direction synchronously, making it convenient for the welding gun to continue welding.

[0066] As the turntable 3 rotates again, the entire device returns to its initial state. This cycle, driven by the rotation of the turntable 3 and the coordination between the push rod 331 and the flap 332, achieves the displacement of the chuck 1. Combined with the position adjustment of the slide 2 and the stable support of the sleeve 23, this effectively solves the problem of welding reinforcements when the welding gun is parallel to the weld seam, avoiding the operator's complex adjustment process, reducing the risk of component displacement, and improving welding efficiency and accuracy.
