Description

Technical Field

[0001] This utility model relates to the field of welding technology, and in particular to a welding device for irregularly shaped pipe fittings. Background Technology

[0002] Welding is a common method in machining to connect several independent profiles. However, without a proper positioning fixture, the welding quality is extremely unstable, the profiles are difficult to position, and they are prone to falling off.

[0003] For irregularly shaped pipe fittings, it is usually necessary to weld round tubes to both ends of the intermediate workpiece. The conventional method is to make positioning marks on the round tubes and the workpiece, and then weld them together using the markings. However, this method has low processing efficiency, and there is a tendency for angular deviations between the round tubes at both ends, which cannot meet the dimensional requirements of irregularly shaped pipe fittings. After welding, correction processing is also required, which increases the cost of parts and is not conducive to large-scale industrial production. Utility Model Content

[0023] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other.

[0024] Please see Figures 1-4This utility model provides a welding device for irregularly shaped pipe fittings, including a fixing device 100 and an irregularly shaped pipe fitting 200. The irregularly shaped pipe fitting 200 includes a workpiece A 201 in a bent shape and pipe fittings B 202 and C 203 respectively disposed at both ends of the workpiece A 201. The fixing device 100 includes a base plate 110 and a contour fixing seat 120, a first positioning mechanism 130 and a second positioning mechanism 140 disposed thereon. The contour fixing seat 120 has a first mounting groove 121 that mates with the workpiece A 201. The first mounting groove 121 has a horizontal section and an inclined section. The contour fixing seat 120 is provided with a first quick clamp 123 located above the horizontal section and a second quick clamp 124 located above the inclined section. The first positioning mechanism 130 is used to fix the pipe fitting B. 202, the first positioning mechanism 130 includes a first fixed seat 131 and a first clamping member 132. The first fixed seat 131 is mounted on the base plate 110 and close to the horizontal section. The second positioning mechanism 140 is used to fix the pipe fitting C 203. The second positioning mechanism 140 includes a second fixed seat 141 and a second clamping member 142. The bottom of the second fixed seat 141 is mounted on the inclined block 143 and close to the inclined section.

[0025] Since workpiece A 201 is bent, when pipe B 202 is fixed vertically, pipe C 203 can only be fixed at an angle. Therefore, the second fixing seat 141 is installed on the tilting block 143 so that pipe C 203 is tilted and positioned, and then the second clamping member 142 is used to clamp it directly above pipe B 202.

[0026] To ensure that the clamping component can clamp pipes at different placement angles from the front, this utility model provides a rotary clamping component. Specifically, the first / second clamping component includes a rotating fixed base 1321, a rotating arm 1322, a connecting rod 1323, and a cylinder. The middle part of the rotating arm is pivotally connected to the rotating fixed base 1321. One end of the rotating arm is provided with a pressure block 1325, and the other end of the rotating arm is pivotally connected to one end of the connecting rod 1323. The other end of the connecting rod 1323 is pivotally connected to the output end 1324 of the cylinder. By controlling the rise of the output end of the cylinder, the rotation of the rotating arm can be driven, thereby causing the pressure block 1325 to press the pipes downward.

[0027] Furthermore, the rotating arm has a bent shape with an included angle, and the rotating arm is pivotally connected to the rotating fixed seat 1321 at the included angle position. Due to the lever principle, the included angle is an obtuse angle, thereby saving the output force of the cylinder.

[0028] Furthermore, a top block 126 is provided at the bottom of the first mounting groove 121. The bottom of the top block 126 is connected to the output end of the intermediate cylinder to achieve lifting. The top block 126 can lift the workpiece A 201 upward from the bottom, thereby facilitating the removal of the product.

[0029] In this embodiment, the irregular tube fitting 200 also includes workpieces D 204 respectively disposed on both sides of workpiece A 201, and the two sides of the contour fixing seat 120 are provided with second mounting grooves 122 that match workpiece D 204, and the contour fixing seat 120 is provided with a third quick clamp 125 located above the second mounting grooves 122.

[0030] In this embodiment, the irregular-shaped pipe fitting 200 also includes a workpiece E 205 disposed at one end of the pipe fitting B 202, and the fixing device 100 also includes an ear positioning plate 150. The ear positioning plate 150 is "Y" shaped, and one of the top ends of the ear positioning plate 150 matches the shape of the workpiece E 205. A fourth quick clamp 151 is provided on the other top end of the ear positioning plate 150.

[0031] Operating Procedures: First, place workpiece A 201 in the first mounting slot 121 of the profile fixing base 120. Then, place pipe fittings B 202 and C 203 on the first fixing base 131 and the second fixing base 141 respectively. Activate the cylinder to clamp the two pipe fittings using the first clamping member 132 and the second clamping member 142. Then, use the first quick clamp 123 and the second quick clamp 124 to clamp workpiece A 201. Next, place the two workpieces D 204 into the second mounting slot 122 of the profile fixing base 120 and clamp them using the third quick clamp 125. Place workpiece E 205 on the corresponding top of the ear positioning plate 150 and clamp it using the fourth quick clamp 151. After completing the above steps, perform welding. After welding, open the cylinder and all quick clamps and use the intermediate cylinder to eject the product.

[0032] In summary, this utility model provides a simple and quick-positioning fixing device that can accurately position the pipe fittings at both ends. Utilizing the rotating structure of the clamping component, it can clamp the pipe fittings from the front, avoiding dimensional errors caused by positional and angular misalignments. Furthermore, the device is easy to operate, effectively improving production efficiency and reducing costs. Therefore, this utility model effectively overcomes the various shortcomings of existing technologies and has high industrial application value.
