Description

Technical Field

[0001] This utility model relates to the field of welding torch equipment, specifically a plasma cladding welding torch adjustment device. Background Technology

[0002] Micro-beam plasma cladding, also known as plasma cladding technology, is a welding process that uses a micro-beam plasma arc as a heat source and alloy powder as filler metal to heat and melt the alloy powder together with the substrate surface to form an alloy layer.

[0003] However, in practical use, the length of the welding torch is fixed and cannot be extended or shortened according to the usage conditions, which reduces the service life of the welding torch. At the same time, when welding seams with an inclined angle, it is necessary to manually rotate the welding torch to the welding position and then maintain the angle for welding. When the welding torch connected to the pipe rotates as a whole, it is easy to cause the connected pipe to twist. The pipe has a tendency to reset, which affects the welding stability of the welding torch. Therefore, there is an urgent need for a device to solve the above problems. Utility Model Content

The collar is fixed to one side of the electric push rod and is movably sleeved on the outside of the movable rod. The limiting ring is fixed around the outside of the movable rod. In use, the electric push rod is activated by the first control switch. The electric push rod extends and, through the collar and the limiting ring, drives the movable rod to move along the inside of the hollow rod. This facilitates the adjustment of the distance between the welding torch body and the welding head, thereby improving the practicality of the device.

The fixed frame is fixed to one side of the collar, the motor is fixed to one side of the fixed frame, the second control switch is embedded and fixed to the top of the welding torch body, the worm is fixed at the output end of the motor, and the worm gear is fixed around the outside of the movable rod. The worm gear meshes with the worm. When it is necessary to adjust the welding direction of the welding head, the motor is started, and the motor drives the worm to rotate, which in turn drives the worm gear to rotate, causing the movable rod to rotate inside the hollow rod, thereby adjusting the orientation of the welding head and facilitating welding work at different angles.

[0008] Preferably, the first control switch is electrically connected to the electric push rod.

[0009] Preferably, the second control switch is electrically connected to the motor.

[0010] Preferably, two limiting rings are provided, located on both sides of the collar, to facilitate limiting the position of the collar.

The electric push rod extends and, through the collar and the limiting ring, drives the movable rod to move along the inside of the hollow rod. This facilitates the adjustment of the distance between the welding torch body and the welding head, thereby improving the practicality of the device. When it is necessary to adjust the welding direction of the welding head, the motor is activated. The motor drives the worm gear to rotate, which in turn drives the worm wheel to rotate, causing the movable rod to rotate inside the hollow rod. This allows the orientation of the welding head to be adjusted, making it suitable for welding work at different angles. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a plasma cladding welding torch adjustment device, including a welding torch body 1 and a welding head 7. A connecting pipe is installed on one side of the welding torch body 1. On one side of the welding torch body 1, there is an adjustment mechanism between the welding torch body 1 and the welding head 7 to facilitate adjusting the distance between the welding head 7 and the welding torch body 1. There is a rotation mechanism on the outside of the adjustment mechanism to facilitate rotating the welding head 7.

[0021] The adjustment mechanism includes a hollow rod 2, a movable rod 3, a first control switch 4, an electric push rod 6, a collar 8, and a limiting ring 13. The hollow rod 2 is welded and fixed to one side of the welding torch body 1. The movable rod 3 is movably inserted inside the hollow rod 2, and a vent hole is opened at the center of the movable rod 3. The first control switch 4 is embedded and fixed at the top of the welding torch body 1. The electric push rod 6 is fixed to one side of the welding torch body 1 by bolts. The collar 8 is fixed to one side of the electric push rod 6 by bolts and is movably sleeved on the outside of the movable rod 3. The limiting ring 13 is welded and fixed around the outside of the movable rod 3. There are two limiting rings 13, located on both sides of the collar 8, to facilitate limiting the position of the collar 8. The outside of the movable rod 3 and the inside of the hollow rod 2 are in movable sealed contact. In use, the electric push rod 6 is activated by the first control switch 4. The electric push rod 6 extends and moves the movable rod 3 along the inside of the hollow rod 2 through the collar 8 and the limiting ring 13. This facilitates the adjustment of the distance between the welding torch body 1 and the welding head 7, thereby improving the practicality of the device.

[0022] The rotating mechanism includes a fixed frame 9, a motor 10, a second control switch 5, a worm gear 12, and a worm 11. The fixed frame 9 is fixed to one side of the collar 8 by bolts. The motor 10 is fixed to one side of the fixed frame 9 by a mounting bracket. The second control switch 5 is embedded and fixed to the top of the welding torch body 1. The worm 11 is fixed to the output end of the motor 10 by a coupling. The worm gear 12 is welded and fixed around the outside of the movable rod 3. The worm gear 12 meshes with the worm 11. When it is necessary to adjust the welding direction of the welding head 7, the motor 10 is started. The motor 10 drives the worm 11 to rotate, which in turn drives the worm gear 12 to rotate, so that the movable rod 3 rotates inside the hollow rod 2. This allows the orientation of the welding head 7 to be adjusted, making it convenient for welding work at different angles.

[0023] The first control switch 4 is electrically connected to the electric push rod 6.

[0024] The second control switch 5 is electrically connected to the motor 10.

[0025] Working principle: During use, the electric push rod 6 is activated by the first control switch 4. The electric push rod 6 extends and moves the movable rod 3 along the inside of the hollow rod 2 through the collar 8 and the limiting ring 13. This facilitates the adjustment of the distance between the welding torch body 1 and the welding head 7, thereby improving the practicality of the device. When it is necessary to adjust the welding direction of the welding head 7, the motor 10 is activated. The motor 10 drives the worm gear 11 to rotate, which in turn drives the worm wheel 12 to rotate, causing the movable rod 3 to rotate inside the hollow rod 2. This allows the orientation of the welding head 7 to be adjusted, making it convenient for welding work at different angles.
