[0030] The following further explains and illustrates the present utility model in conjunction with specific embodiments.

[0031] Such as Figures 1 - 5As shown in the figure, a multi-axis welding device for parts provided in this embodiment includes a base 1. The base 1 is connected to a motor 3 through a gear drive shaft 12. A drive shaft 4 is arranged on one side of the motor 3. The drive shaft 4 is movably connected to a drive arm 5. A drive shaft A6 is arranged at the upper end of the drive arm 5. The drive shaft A6 is movably connected to a telescopic arm 7. The front end of the body of the telescopic arm 7 is connected to a welding fixture head 8 through a drive shaft B10; the body of the telescopic arm 7 can be telescoped to adjust the distance between the welding fixture head 8 and the workpiece; a bottom support 2 is fixed on the upper surface of the base 1. A gear drive shaft 12 is installed on the upper surface of the bottom support 2. The gear drive shaft 12 is connected to the motor 3. The gear drive shaft 12 is in a horizontal plane and rotates 360 degrees; in this embodiment, the base 1 is fixed to the ground by a screw. A bottom support 2 is fixed on the upper surface of the base 1. A gear drive shaft 12 is adaptively arranged in the central area of the upper surface of the bottom support 2. The gear drive shaft 12 is driven by the output shaft of the motor 3 arranged above to realize a 360-degree horizontal rotation. The gear drive shaft 12 is an existing product on the market and will not be elaborated here; the gear drive shaft 12 meets the welding requirements in different directions. Users do not need to change the position of the welding device, improving the automation degree and welding efficiency of the welding device. The lower end of the drive arm 5 is connected through a drive shaft 4. The drive shaft 4 realizes a forward and backward rotation of 0 to 180 degrees through the motor 3; a motor is arranged on any cross-section of the drive shaft 4. The output shaft of the motor is connected to the drive shaft 4. The drive shaft 4 is fixed to one side of the motor 3 through the support frame of the welding device. The support frame of the welding device is an existing product or tooling and will not be elaborated here. The drive shaft 4 realizes a forward and backward rotation of 0 to 180 degrees through the motor 3; the drive arm realizes an up and down adjustment of 0 to 180 degrees through the drive shaft to meet the heights of different weldings and realize multi-axis welding; the drive arm realizes a forward inclination welding operation through the change of the angle. Since the body of the drive shaft 4 is large in volume and the drive shaft angle is large and difficult to control the precision, the forward inclination welding precision is low and the error is high. The use of the drive arm in the welding of special-shaped workpieces is not ideal; the upper end of the drive arm 5 is connected to the rear end of the telescopic arm 7 through a drive shaft A6. The telescopic arm 7 can rotate up and down by 0 to 90 degrees. A motor is installed on one side of the drive shaft A6. The motor drives the drive shaft A6. The drive shaft A6 drives the telescopic arm 7 to rotate up and down by 0 to 90 degrees. The telescopic arm realizes the adjustment of the up and down angle through the drive shaft A6 to meet different welding requirements. Through the gear drive shaft 12, the drive shaft 4 and the drive shaft A6 in the welding device, the three cooperate with each other to realize the multi-axis welding of parts, meet the heights of different weldings, realize multi-axis welding, and improve the welding efficiency.

[0032] As Figures 2 - 4As shown in the figure, a motor A11 and a wire passing hole 9 are respectively arranged at the tail end of the telescopic arm 7. The wire passing hole 9 penetrates through the body of the telescopic arm 7 and extends to the bottom of the welding fixed head 8. A telescopic rod 13 is nested in the inner cavity of the telescopic arm 7 in a matching manner. The top of the telescopic rod 13 is connected to a U-shaped driving shaft B10. The welding fixed head 8 is connected inside the driving shaft B10, and the welding fixed head 8 is adapted to the welding torch. The body of the telescopic rod 13 can be extended or retracted by 0 to 50 cm. By extending or shortening the distance of the telescopic rod 13, the welding of special-shaped workpieces can be realized. The telescopic arm is an existing electric product. The motor A11 is located at the tail end of the telescopic arm. The motor A11 drives the telescopic rod 13 in the inner cavity of the telescopic arm 7, so that the telescopic rod 13 can be extended or retracted, and then the distance between the telescopic rod 13 and the workpiece can be adjusted. The wire passing hole 9 penetrates through the body of the telescopic arm 7. The wire harness and the solder pipe of the welding torch are conveyed to the welding torch through the wire passing hole 9 and the welding fixed head 8. One telescopic rod 13 is nested in the telescopic arm 7 in a matching manner. The top of the telescopic rod 13 is fixed with a U-shaped driving shaft B10. The welding fixed head 8 is connected inside the driving shaft B10 through a shaft rod. The welding fixed head 8 is adapted to the welding torch. Through the telescopic rod 13 in the telescopic arm 7, without adjusting the angle of the telescopic arm 7, or adjusting the angle of the telescopic arm 7 and the length and shortness of the telescopic rod 13, the distance between the telescopic rod 13 and the special-shaped workpiece can be realized, and the sunken area of the workpiece can be welded. The design of the telescopic arm 7 solves the problem of welding the sunken area of the special-shaped workpiece without changing the processing line and without the special-shaped workpiece being able to rotate, improving the welding efficiency and welding quality.

[0033] As Figures 3 - 5 shown, the driving shaft B10 is a U-shaped body. A welding fixed head is connected inside the U-shaped body through a shaft rod. Notches A15 are respectively arranged at both ends of the shaft rod body. The notches A15 are used for the limit and fixation of the wire speed. A plurality of notches 14 are arranged at the top of the body of the telescopic arm 7. The notches 14 are used for the limit and fixation of the wire speed. Through the notches A15 arranged at both ends of the U-shaped body of the driving shaft B10 and the plurality of notches 14 arranged at the top of the body of the telescopic arm 7, it is convenient to fix and limit various wire harnesses of the welding equipment in the notches, improving the overall aesthetics and regularity of the welding equipment. At the same time, the fixed wire harness does not affect the normal operation of the welding equipment.

[0034] This embodiment also provides the working principle of a multi-axis welding device for components: The user sets the operating program of the welding device through the display terminal, and monitors whether each motor is powered on, whether the driving shafts are normal, and whether the welding torch and welding material are normal through the program. After the automatic detection is error-free, the user sets the welding program through the display terminal. After ensuring that the welding program is consistent with the welding part of the workpiece, the welding device precisely adjusts the angles of each driving shaft, driving arm, telescopic arm, and telescopic rod from bottom to top in sequence through the program. After the angles and orientations are set, the user starts the welding operation through the display terminal. After the first special-shaped workpiece is welded, the first special-shaped workpiece is inspected for welding quality. After the first-piece inspection is qualified, the program continues to be executed for welding. If problems such as uneven weld beads or missed welding occur in the first special-shaped workpiece, adjust the welding program parameters and perform welding and inspection again.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
