Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, specifically to an automatic positioning welding device for purlin support plates. Background Technology

[0002] Purlin support plates, as an important component in building structures, primarily function to support purlins and transfer loads. Purlins are typically used to connect the upper and lower structures of the roof, bearing the task of transferring roof loads to the supporting structure. Purlin support plates are installed below the purlins and, through their connection with the main structural beams, transfer the loads on the purlins to the main structure, thereby maintaining the stability and safety of the entire building structure. During use, purlin support plates require welding. Welding guns are an essential tool in this process. However, existing welding guns, which rely on manual fixing during welding, can easily cause injury to workers. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an automatic positioning and welding device for purlins that combines welding and positioning, thus solving the problem of dangerous manual fixing operations.

[0004] To address the problems existing in the background technology, this utility model adopts the following technical solution: It includes a device platform, a support frame at one end of the platform, a material transfer roller on the support frame, and a positioning mechanism on one side of the material transfer roller. The positioning mechanism includes a handwheel, an eccentric wheel, and a positioning clamping block, with two handwheels, two eccentric wheels, and two positioning clamping blocks. The two handwheels are symmetrically arranged, and each handwheel is connected to a corresponding eccentric wheel via a transmission shaft. The transmission shaft passes through the support block, and positioning clamping blocks are installed on the eccentric wheels, with the two positioning clamping blocks positioned opposite each other. A support platform is provided on the other side of the positioning mechanism, with two columns on the platform, positioned opposite each other. A sliding groove is opened on one side of each column, and a lifting plate is provided between the two sliding grooves. Pulleys are fixedly installed on both sides of the lifting plate, and the pulleys are slidably connected to the sliding grooves. A welding gun is provided at the bottom of the lifting plate, and the top of the lifting plate is connected to the plunger rod of a cylinder. The cylinder is located on a crossbeam between the two columns and is connected to a gas storage chamber, which is installed on the columns.

[0005] The beneficial effects of this utility model are: This utility model combines the positioning mechanism and the welding gun, which solves the problem of manual positioning and dangerous operation during the welding process. Attached Figure Description

[0007] Reference Figure 1The present invention specifically adopts the following implementation method: it includes a device platform 6, a support frame 1 at one end of the device platform 6, a material transfer roller 2 on the support frame 1, a positioning mechanism on one side of the material transfer roller 2, the positioning mechanism includes a handwheel 3, an eccentric wheel 4 and a positioning clamping block 5, there are two handwheels 3, two eccentric wheels 4 and two positioning clamping blocks 5, the two handwheels 3 are symmetrically arranged, the two handwheels 3 are respectively connected to the corresponding eccentric wheels 4 through a transmission shaft, the transmission shaft passes through the support block, and positioning clamping blocks 5 are respectively installed on the eccentric wheels 4, the two positioning clamping blocks 5 are set opposite to each other; The positioning mechanism is provided on the other side of a platform 13, on which two columns 14 are provided. The two columns 14 are positioned opposite each other, and each of the two columns 14 has a sliding groove 7 on its opposite side. A lifting plate 10 is provided between the two sliding grooves 7. Pulleys 8 are fixedly installed on both sides of the lifting plate 10. The pulleys 8 are slidably connected to the sliding grooves 7. A welding gun 11 is provided at the bottom of the lifting plate 10. The top of the lifting plate 10 is connected to the plunger rod of a cylinder 12. The cylinder 12 is located on a crossbeam between the two columns 14. The cylinder 12 is connected to an air storage chamber 9, which is installed on the columns 14.

[0008] When using this automatic positioning and welding device for purlin support plates, the purlin support plate is conveyed to the positioning mechanism via the transfer roller. Rotating the two handwheels 3 causes the eccentric wheel 4 connected to them to rotate. The eccentric wheel 4 causes the positioning clamps 5 to move closer or further apart, placing the purlin support plate between the two positioning clamps 5. Rotating the handwheel 3 in the opposite direction clamps the purlin support plate with the positioning clamps 5. Activating the cylinder 12 causes the plunger rod of the cylinder 12 to push the welding gun 11 up and down. When welding is required, the welding gun 11 moves downwards to contact the purlin support plate between the positioning clamps 5, completing the welding operation.

[0009] In summary, this automatic positioning and welding device for purlin support plates is easy to use. By combining the positioning mechanism with the welding gun, it solves the problems of manual positioning and dangerous operations during the welding process.
