[0032] In order to better understand the purpose, structure and function of the present invention, the following is a further detailed description of a component auxiliary welding device of the present invention in conjunction with the accompanying drawings.

[0033] like Figure 1-Figure 7As shown, an embodiment of the utility model provides a component auxiliary welding device, including a first support frame 100, which is used to support and install the component to be welded. A second support frame 200 symmetrically installed with the first support frame 100 is also provided on one side of the first support frame 100, and a fixing portion 300 for supporting and placing the welding position is further provided in the middle of the first support frame 100 and the second support frame 200. The first support frame 100 and the second support frame 200 are slidably installed on the upper surface of the fixed base 500 arranged at the lower end, and the fixing portion 300 is fixedly installed in the middle of the fixed base 500. A welding robot arm 400 for performing welding operations on the parts to be welded is provided on one side of the fixed base 500.

[0034] The second support frame 200 includes a first clamping frame 210 and a second clamping frame 250 for fixing parts. The second clamping frame 250 is installed on the upper end of the support plate 230 set at the lower end through the support feet fixed on the lower side and fixed by bolts. The two sides of the first clamping frame 210 are fixed by movably installed rotating screws 260.

[0035] The lower end of the rotating screw 260 is provided with a positioning head 262 for supporting the rotation of the rotating screw 260. The positioning head 262 is installed on the upper surface of the support plate 230. The upper end of the rotating screw 260 is movably installed with a fastening nut 261 for fastening the rotating screw 260 in place. The rotating screw 260 is snap-fitted into the inside of the snap-fitting groove 212 set on both sides of the first clamping frame 210 and matches the size of the rotating screw 260.

[0036] When welding larger parts, the two groups of parts to be welded can be placed on the upper ends of the first support frame 100 and the second support frame 200 for support, and then the welding robot arm 400 installed on one side performs the welding operation. When welding plate-shaped or tubular parts, they can be placed on the upper ends of the first support frame 100 and the second support frame 200, and the first clamping frame 210 set at the upper end can be clamped at the upper end. After fitting, the rotating screws 260 on both sides are rotated to engage them in the engaging grooves 212, and then the fastening nuts 261 at the upper end are rotated and tightened, so that the first clamping frame 210 installed on the upper end can be fixed, and the parts to be welded at the lower end can be clamped. The rotating screw 260 has a large adjustable range and is flexible to operate. The first clamping frame 210 and the second clamping frame 250 set at the same time can be fixed to plate-shaped or tubular parts, which is more flexible.

[0037] The middle parts of the first clamping frame 210 and the second clamping frame 250 are both arranged in a closed and inclined shape, and the first clamping frame 210 and the second clamping frame 250 are arranged symmetrically, which can effectively position and support the tubular parts and facilitate welding processing.

[0038] Both sides of the first clamping frame 210 are provided with through holes 211 for auxiliary support of the first clamping frame 210. A vertical rod 220 for supporting the first clamping frame 210 is slidably installed inside the through hole 211. The lower end of the vertical rod 220 is fixedly installed on the upper end of the support plate 230, and the vertical rod 220 is slidably installed inside the through hole 211. When the first clamping frame 210 is pressed down and tightened, the vertical rod 220 passes through the through hole 211 for auxiliary positioning support to prevent the first clamping frame 210 from offsetting and rotating during installation, resulting in poor fixing effect.

[0039] A ball 213 is movably installed in the inner wall of the through-hole 211 to assist its sliding. The ball 213 is slidably installed inside the grooves opened on both sides of the vertical pole 220, which facilitates the first clamping frame 210 to slide on the upper end of the vertical pole 220, reduces friction, facilitates installation, and reduces wear.

[0040] The lower ends of the second clamping frames 250 of the first support frame 100 and the second support frame 200 are provided with rotating shafts 251 for connecting and supporting the second clamping frames 250. The rotating shafts 251 are movably installed inside the frames on both sides of the second clamping frames 250 through bearings. The circular tubular parts at the upper ends can rotate to assist the parts welding operation.

[0041] A cavity 520 is provided in the inner cavity of the fixed base 500, and fixed guide rails 530 are provided on both sides of the cavity 520 for driving the first support frame 100 and the second support frame 200 to move. A pneumatic slider 240 is slidably installed on the upper end of the fixed guide rail 530 for driving the first support frame 100 and the second support frame 200 to move. The pneumatic slider 240 is fixedly installed at the lower end of the support plate 230 and is slidably installed inside the slide groove 510 provided on the upper surface of the fixed base 500. The fixed guide rails 530 and the pneumatic slider 240 corresponding to the lower ends of the first support frame 100 and the second support frame 200 are respectively divided into two groups and are controlled separately. During the welding process, the guide rail cylinder adjusts the position, and the pneumatic slider 240 moves on the upper end of the fixed guide rail 530, so that the position of the welding point can be adjusted, which is convenient for adjusting the position according to the welding conditions of the parts.

[0042] The size and shape of the fixing part 300 and the second clamping frame 250 match each other. The lower end of the fixing part 300 is supported by the plate body 330. The fixing part 300 is fixedly installed in the middle of the fixed base 500. The lower end of the fixing part 300 is provided with a rotating rod 310 for driving the lower end parts to rotate and assist in welding. A driving part 320 is provided on one side of the rotating rod 310. The driving part 320 is composed of a driving motor and a reducer, and the output end drives the rotating rod 310 to rotate through a transmission belt. When it is necessary to rotate the tubular parts, the rotating rod 310 can be driven to rotate by the driving part 320, thereby assisting the rotation of the parts installed on the upper end, thereby facilitating the welding operation.

[0043] The working principle of a component auxiliary welding device is as follows: when performing welding operations on larger components, the two groups of components to be welded can be placed on the upper ends of the first support frame 100 and the second support frame 200 for support, and then the welding robot arm 400 installed on one side performs the welding operation. When welding plate-shaped or tubular components, they can be placed on the upper ends of the first support frame 100 and the second support frame 200, and the first clamping frame 210 set at the upper end is clamped at the upper end. After fitting, the rotating screws 260 on both sides are rotated to engage them in the engaging grooves 212, and then the fastening nuts 261 at the upper end are rotated and tightened, so that the first clamping frame 210 installed on the upper end can be fixed, and the components to be welded at the lower end can be clamped. The rotating screw 260 has a large adjustable range and is flexible to operate. The first clamping frame 210 and the second clamping frame 250 set at the same time can be fixed to plate-shaped or tubular components, which is more flexible.

[0044] It is understood that the present invention is described by way of certain embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. Furthermore, under the guidance of the present invention, these features and embodiments may be modified to suit specific circumstances and materials without departing from the spirit and scope of the present invention.
