Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, specifically to an ultrasonic stud welding machine for automotive roof lights. Background Technology

[0002] The dome light bracket is secured with studs for easy connection to the vehicle body. Both the dome light bracket and the studs are metal structures, and an ultrasonic stud welding machine is used for the fixed connection. An ultrasonic stud welding machine is an advanced device that uses high-frequency ultrasonic vibration to weld metal studs to workpieces. Its technology integrates ultrasonic processing, pressure welding, and automation control technologies.

[0003] Existing ultrasonic stud welding machines are operated by hand. During hand operation, it is impossible to ensure that the welding gun is completely perpendicular to the joint surface of the workpiece. The stud is tilted after fixing, which is not convenient for installation. In addition, existing welding guns use a limiting structure to keep the fixed bolt perpendicular to the fixing surface. However, the limiting structure can only limit the welding angle of the stud and cannot guarantee the accuracy of the welding position. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-7 As shown, this utility model is an ultrasonic stud welding machine for automotive roof lights, including a base plate 1. Four evenly distributed support feet 2 are installed on the bottom surface of the base plate 1. A stand is installed on the base plate 1, and a welding end 6 is installed on the stand. A rotating table 7 located below the welding end 6 is installed on the base plate 1. The rotating table 7 has at least two workstations, and each workstation is equipped with a clamp 8. A roof light bracket 10 is placed on the clamp 8.

[0028] At least one clamp 8 is located directly below the welding end 6, and the stud is welded and fixed to the middle of the top light bracket 10 through the welding end 6;

[0029] like Figures 5-6 As shown, the rotating table 7 has two workstations. One workstation is located directly below the welding end 6, where the welding end 6, which is secured with a stud, moves downward to perform welding work. The other workstation is located away from the welding end 6, so that the welding work is not affected during the disassembly and installation of the ceiling light bracket 10.

[0030] Compared to a single workstation, a dual workstation separates the workpiece assembly and disassembly from the welding process, effectively improving work efficiency.

[0031] The fixture 8 is provided with a slot 801, and a ceiling light bracket 10 is placed in the slot 801. The bottom surface of the slot 801 is provided with a protrusion 802, which cooperates with the positioning hole provided on the ceiling light bracket 10.

[0032] The width of the slot 801 is the same as the width of the ceiling light bracket 10. The slot 801 is used to limit and fix the ceiling light bracket 10. The slot 801 has chamfered structures on its two sides, which increases the opening of the slot 801, making it easier to insert the ceiling light bracket 10.

[0033] Additionally, the protrusion 802 added to the bottom surface of the slot 801 cooperates with the ceiling light bracket 10 to prevent the ceiling light bracket 10 from sliding. At the same time, the top of the protrusion 802 is a pointed tip. During welding, the bottom end of the welding end 6 is equipped with a stud, and the bottom end of the stud is pressed tightly against the upper surface of the ceiling light bracket 10. During the pressing process, the positioning hole of the ceiling light bracket 10 slides downward along the protrusion 802 until it is in a limited engagement.

[0034] A column 102 is mounted on the base plate 1. A sleeve 701 is provided on one side of the rotating table 7 and is fitted onto the column 102. A handle 702 is installed on the outer side of the sleeve 701.

[0035] The bottom end of the column 102 may be provided with external threads. The column 102 is installed in the screw hole provided on the base plate 1 through the external threads. Both the base plate 1 and the column 102 may be made of stainless steel. The rotating table 7 rotates around the column 102 through the sleeve 701.

[0036] During the rotation, the rotating platform 7 is pushed around the column 102 by holding the handle 702.

[0037] like Figure 4 As shown, a limiting member 9 is installed on the bottom surface of the substrate 1. The limiting member 9 is in a limiting fit with the rotating table 7. The substrate 1 has multiple through holes 101. The limiting member 9 includes a support plate 901 fixed to the bottom surface of the substrate 1. The support plate 901 has multiple deep holes 902 corresponding to the through holes 101. A spring 904 and a top post 903 are placed in the deep holes 902. The top end of the top post 903 extends out of the through hole 101. The rotating table 7 has multiple round holes 703. The round holes 703 are in a limiting fit with the top post 903.

[0038] There are three through holes 101. The three through holes 101 are evenly distributed around the column 102 at 180°. The central angle between two adjacent through holes 101 is 90°. The spherical end of the top column 903 extends out of the through holes 101.

[0039] When the rotating platform 7 rotates, the side of the rotating platform 7 pushes the top column 903 to compress the spring 904, so that the top column 903 retracts into the through hole 101. By moving the top column 903 up and down, the problem of the top column 903 obstructing the rotation of the rotating platform 7 is solved. The round hole 703 moves to the corresponding through hole 101, and the top of the top column 903 fits into the round hole 703, thus completing the limitation of the rotating platform 7.

[0040] The problem of the rotating table 7 deflecting during the welding process is solved by the limiting fit between the top column 903 and the round hole 703.

[0041] like Figure 7 As shown, the support frame includes two vertically mounted uprights 3 on the base plate 1, a crossbeam 5 between the two uprights 3, and a welding end 6 mounted on the crossbeam 5. An angle bracket 4 is installed between the base plate 1 and the uprights 3.

[0042] The welding end 6 includes a back plate 601 fixed to the crossbeam 5. A guide rod 602 and a telescopic rod 603 are installed on the back plate 601. The movable ends of the guide rod 602 and the telescopic rod 603 are fixed on the base plate 605. A welding machine 604 is installed on the base plate 605.

[0043] The welding machine 604 is located directly above the fixture 8.

[0044] The welding machine 604 uses a universal stud welding gun, which is vertically mounted on the base plate 605. The stud welding gun has a screw hole on the periphery of the nozzle end, and the bolts on the base plate 605 are installed in the screw hole.

[0045] During operation, the telescopic rod 603 extends and pushes the base plate 605 connected to the bottom end of the telescopic rod 603 downward, and drives the welding machine 604 on the base plate 605 to move down until the stud sleeved at the bottom end of the welding machine 604 contacts the top light bracket 10, thus completing the welding work.

[0046] Meanwhile, guide rods 602 are installed on both sides of the telescopic rod 603. The guide rods 602 slide along the guide holes of the fixed seats fixed on the back plate 601 and are fixed to the base plate 605 through the bottom end of the guide rods 602. The two guide rods 602 limit the movement direction of the base plate 605 and ensure the stability of the base plate 605 during movement.
