Description

Rotating Welding Device

The present invention relates to a rotary welding device, and in particular, a corrugated line in which a round tube and a tube are combined as a welding line to chuck a tube on one side and perform welding along a circular welding line.

In general, when a round tube and a tube, or a round rod and a rod are vertically coupled, a correlation line (hereinafter, referred to as a weld line) of the combined portion appears round in the plane and appears as part of an ellipse in the front.

Conventionally, the welding line as described above was impossible to perform a welding operation using a device of a specific device, because the welding line is a three-dimensional curve that is bent on all of the X, Y, and Z axes. This is because the welding device that can perform welding work only in one direction and both directions of the Z axis is not performed.

Therefore, in the welding of the welding line as described above, the worker of the workshop should mainly carry out the welding work by directly holding the welding machine.

As described above, the work by the work worker rather than the work by the mechanical automatic welding device is a factor of the increase in labor costs, and the work object becomes unusable due to the mistake of the unskilled work worker.

In addition, the work of the worker other than the automatic welding method by the machine is a factor that decreases the productivity, the gas generated during the welding work has a problem that adversely affects the health of the worker.

The present invention was devised to solve the above problems, and the object of the present invention is to provide a rotary welding device which is chucked to a vertically temporarily coupled tube or rod to enable the apparatus to automatically perform welding along the welding line. have.

Referring to the operation state and action of the rotary welding device according to the present invention configured as described above in detail.

Referring to Figure 1, by fixing the rotary welding device according to the present invention by using the chucking device 100 to the vertical portion of the workpiece (M) temporarily temporarily orthogonally coupled, the working position is set, the drive device 200 When the driving device 200 is rotated by operation, the positioning device 300 is lifted together with the torch T mounted on the positioning device 300 to be rotated and lifted along the welding line L. Do it.

As the drive device 200 is rotated as described above, the twisting of the cable 2 is released by the anti-twist device 400. Here, if the anti-twist device 400 is not mounted, the torch T may be detached from the clamp 3 and the cable 2 may be loosened when the driving device 200 is rotated once or twice. have.

In the following, such an operating state will be described in detail.

To chuck the workpiece M using the chucking device 100, when the operator rotates the knob 5 to rotate the operating shaft 130 in the state as shown in FIGS. 2 and 3, the operating shaft 130 is rotated. By rotating the operating hole 120 is pushed by the screw thread of the threaded portion 131.

Here, each of the operating holes 120 mounted on the guide hole 111 are all operated at the same time, which is bevel gear 141 of the linkage device 140 are all coupled even if only one operation shaft 130 is rotated It is in a working state.

When the operating tool 120 flows as described above, the jaw 121 coupled with the operating tool 120 also flows, and the jaws 121 are simultaneously extended or narrowed to closely contact the inner surface or the outer surface of the workpiece M. The installation of the welding device for performing the work is completed.

When the installation is completed as described above, the operator applies the power to the motor 211 of the drive device 200 to rotate the motor 211.

When the motor 211 is driven as described above, the spur gear 221 coupled with the pinion 212 of the motor 211 should be rotated, but the spur gear 221 is disposed on the housing 110 and the fixed shaft 220. Since it is fixed, the base 1 on which the motor M is mounted is rotated about the fixed shaft 220.

When the base 1 is rotated as described above, the torch T mounted on the elevating device 230, the positioning unit 300, and the positioning device 300 of the driving device 200 is also fixed shaft 220. It is rotated around.

Here, when the lifting device 230 is rotated around the fixed shaft 220, the lifting device 230 is a bevel gear 232 shown in Figure 4 by the bevel gear 222 of the fixed shaft 220 The rotating shaft 231 is rotated, and at the same time, the cam member 233 coupled with the rotating shaft 231 is rotated, and the cam protrusion 234 is eccentric from the rotating shaft 231 by the rotation of the cam member 233. The rotary lever is rotated while drawing a circular trajectory to flow the movable lever 235 in the state shown in FIG.

6 shows a state in which the movable lever 235 is repeatedly rotated by a predetermined angle about the center member 242 of the flow center device 240. Accordingly, the movable lever 235 and the hinge coupling are shown. The connector 260 is lifted up and down, and thus the positioning device 300 and the torch T, which are coupled with the connector 260, are lifted and perform welding work.

Here, when the driving device 200 is rotated once, the lifting device 230 has to reciprocate up and down twice, which means that the welding line L of the workpiece M shown in FIG. This is because the top and bottom of each of the two times exist.

In addition, in order to adjust the upper and lower flow width of the elevating device 230, it is necessary to adjust the flow center device 240, when rotating the knob 5 shown in Figure 5, the guider 241 is a screw rod ( Pushed by the screw thread of 243, the center member 242 mounted on the guider 241 is moved, and the center of repeated rotation of the movable lever 235 is changed.

In more detail, when the center member 242 is moved toward the connector 260 by flowing the guider 241, the rotation width of the connector 260 decreases as in the principle of the lever, and the center member 242 When the cam member 233 is moved to the side, the rotation width of the connector 260 becomes large, and by using this, it is possible to set the working state in accordance with the phase difference between the upper and lower phases present in the welding line L of the workpiece M. .

The positioning device 300 is for setting the working position of the torch T more precisely. When the knob 5 of the screw rod 311 installed to the left and the right is rotated, the lifting device 230 The support 320 coupled to the connector 260 of the should be pushed by the thread of the screw rod 311, but because the support 320 is fixed, the first frame 310 and the second frame reactively 330 flows left and right.

In addition, when the knob 5 of the screw rod 331 provided up and down is rotated, the second frame 330 is operated by the same action of the screw rod 330 of the first frame 310 and the supporter 311. Flowing up and down with respect to the connecting rod 340, the bracket 350 coupled to the second frame 330 and the torch T mounted on the bracket 350 flows up and down.

Due to the action of the first frame 310 and the second frame 330 as described above it is possible to adjust the interval between the discharge port of the torch (T) and the welding line (L).

As described above, the anti-twist device 400 has a cylinder 410 fixing the first gas pipe 420 connected to the cable 2 when the drive device 200 is rotated so that the cable 2 is twisted. Rotation with respect to the gas pipe 430 is to be untwisted. At this time, the end of each terminal 412 in contact with the power connector 440 is slid from the outer surface of the power connector 440, and is always in contact by the elasticity of the spring 413.

In addition, the compression coil spring 450 serves to closely contact the second gas pipe 430 and the power connector 440 toward the first gas pipe 420.

As described above, the present invention changes the welding work performed by a worker in an operation of joining pipes or rods to an automatic welding method using an apparatus, thereby reducing work expenses due to labor cost reduction and accurate welding. Work objects that can be avoided by the operation of the device is drastically reduced, there is an effect that can reduce the waste of materials.

In addition, it is possible to improve the productivity by accurate and fast work, there is an effect to improve the problem that the health of the worker is deteriorated by the welding gas.
