Description

Technical Field

[0001] This invention relates to the field of drum brake welding equipment, specifically a multi-point welding device for the splicing of assembled parts. Background Technology

[0002] A drum brake is a braking device that uses stationary brake pads inside a brake drum to rub against the rotating brake drum, generating friction to reduce the wheel's rotational speed. The drum brake structure consists of at least two parts assembled and welded together. These parts are relatively small, and the welding points are complex and varied. While manual welding can be performed on each part individually, it is inefficient. Existing welding equipment often uses a single, flexible welding torch, offering high automation but also high purchase costs. However, when dealing with numerous distributed welding points, its adjustments are too frequent and time-consuming, making it impossible to directly and efficiently locate and perform point welding. Therefore, to address these issues, a multi-point welding device for the joints between assembled parts is proposed. Summary of the Invention

[0003] The purpose of this invention is to provide a multi-point welding device for the splicing of assembled parts in order to solve the above-mentioned problems.

[0004] The present invention achieves the above-mentioned objective through the following technical solution: a multi-point welding device for the splicing of assembly parts, comprising a turntable, part assembly fixtures, and a first welding section, a second welding section, and a third welding section arranged sequentially. A plurality of the part assembly fixtures are distributed and installed on the turntable, and each part assembly fixture passes through the first welding section, the second welding section, and the third welding section sequentially via the turntable. The assembly base on each part assembly fixture is provided with welding points A, B, C, D, E, F, and G respectively. Welding points A and F correspond to the first welding gun and the fourth welding gun, respectively; welding points B and G correspond to the second welding gun and the seventh welding gun, respectively; welding point C corresponds to the sixth welding gun; welding point D corresponds to the fifth welding gun; and welding point E corresponds to the third welding gun.

[0005] In a further technical solution, the turntable is connected to an electric drive device located in the middle of the welding machine via a coupling, and a set of welding gun feed supports are distributed on one side of the turntable surface through the positions of each welding gun.

[0006] In a further technical solution, the A weld point is the welding point where the front left end of the second type of part contacts the surface of the third type of part.

[0007] In a further technical solution, the B weld point is the welding point where the front right end of the second type of part contacts the surface of the fourth type of part.

[0008] In a further technical solution, the C-weld point is the welding point where the midpoint of one side edge of the first type of part and the midpoint of the outer edge of the second type of part come into contact.

[0009] In a further technical solution, the D-weld point is the welding point where the left back of the second type of part, the left back of the first type of part, and the third type of part are joined together.

[0010] In a further technical solution, the E-welding point is the welding point where the right back of the second type of part, the right back of the first type of part, and the fourth type of part are joined together.

[0011] In a further technical solution, the F weld point is the welded area where the left front end of the second type of part, the left front end of the first type of part, and the third type of part are joined together.

[0012] In a further technical solution, the G-weld point is the welding point where the right front end of the second type of part, the right front end of the first type of part, and the fourth type of part are joined together.

[0013] The beneficial effects of this invention are: by orderly and centrally setting the welding guns at the welding points, the spot welding shaping process of the parts assembly can be carried out quickly and accurately, and the processing and use costs are low. At the same time, all the welding guns in the second welding part are diagonally distributed, which can meet the welding action requirements of complex front and rear points. It solves the problem that it is inconvenient to carry out welding at multiple welding points due to the complexity of the parts assembly. The welding shaping efficiency is high, which provides a guarantee for the subsequent deep welding processing without deformation. Attached Figure Description

[0021] Please see Figure 1-6 As shown, a multi-point welding device for the splicing of assembly parts includes a turntable 2, a part assembly fixture 3, and a first welding section 4, a second welding section 5, and a third welding section 6 arranged sequentially. Several of the part assembly fixtures 3 are distributed and installed on the turntable 2, and each part assembly fixture 3 passes through the first welding section 4, the second welding section 5, and the third welding section 6 sequentially via the turntable 2. The assembly base 310 on each part assembly fixture 3 is provided with welding points A, B, C, D, E, F, and G. Welding points A and F correspond to the first welding gun 410 and the fourth welding gun 520, respectively; welding points B and G correspond to the second welding gun 420 and the seventh welding gun 610, respectively; welding point C corresponds to the sixth welding gun 540; welding point D corresponds to the fifth welding gun 530; and welding point E corresponds to the third welding gun 510.

[0022] The turntable 2 is connected to the electric drive device located in the middle of the welding machine 1 via a coupling, and a set of welding gun feed supports 8 are arranged on one side of the surface of the turntable 2 through the positions of each welding gun.

[0023] The A weld point is the weld point where the front left end of the second type of part 9 contacts the surface of the third type of part 10.

[0024] The B weld point is the welding point where the front right end of the second type of part 9 contacts the surface of the fourth type of part 11.

[0025] The C weld point is the weld point where the midpoint of one side edge of the first type of part 7 and the midpoint of the outer edge of the second type of part 9 come into contact.

[0026] The D weld point is the welded area where the left back of the second type of part 9, the left back of the first type of part 7, and the third type of part 10 are joined together.

[0027] The E weld point is the welded area where the right back of the second type of part 9, the right back of the first type of part 7, and the fourth type of part 11 are joined together.

[0028] The F weld point is the welded part where the left front end of the second type of part 9, the left front end of the first type of part 7, and the third type of part 10 are joined together.

[0029] The G weld point is the welding point where the front right end of the second type of part 9, the front right end of the first type of part 7, and the fourth type of part 11 are joined together.

[0030] Working principle: The two ends of the second type of part 9 respectively abut against the surfaces of the third type of part 10 and the fourth type of part 11, and are welded to points A and B by the first welding gun 410 and the second welding gun 420 in the first welding section 4. After the first section of welding is completed, it enters the second welding section 5 through the turntable 2: The first type of part 7 is press-fitted and fixed on the assembly base 310, and one side edge of the first type of part 7 abuts against the outer arc edge of the second type of part 9. Its two ends abut against the structural parts welded at points A and B respectively. First, the fifth welding gun 530 and the sixth welding gun 540 are used to weld points D and C respectively, and then the third welding gun 510 and the fourth welding gun 520 are used to weld points E and F respectively. After the second section of welding is completed, it enters the third welding section 6 through the turntable 2: The seventh welding gun is used to weld point G, thereby completing the entire welding. Compared with the prior art, the advantages of this invention are: by setting the welding guns in an orderly and concentrated manner at the welding point distribution, the spot welding shaping process of the parts assembly can be carried out quickly and accurately. At the same time, all the welding guns in the second welding part 5 are diagonally distributed, which can meet the needs of complex front and rear point welding operations. It solves the problem that it is inconvenient to carry out welding at multiple welding points due to the complexity of parts assembly. The welding shaping efficiency is high, which provides a guarantee for the subsequent deep welding processing without deformation.
