Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to a rapid welding device for tubular parts. Background Art

[0002] Welding, also known as fusion, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. There are many sources of energy for modern welding, including gas flame, arc, laser, electron beam, friction and ultrasonic.

[0003] When welding small tubular parts, workers need to first fix the tubular parts to a fixture, and then use welding equipment to weld automatically or manually. Manual welding requires workers to hold the welding equipment for a long time. Due to the uncertainty of manual labor, the quality of the weld is prone to variation. Therefore, most welding work is now done using automatic welding equipment.

[0004] The clamps that come with existing welding equipment are mostly three-jaw chucks. The three-jaw chuck technology is mature and has a good clamping effect. However, when performing the clamping work, the staff needs to use a wrench for manual tensioning. When performing large-scale processing, most of the time is often wasted on clamping and removing parts, affecting the processing efficiency. Therefore, a more efficient welding equipment is needed to improve the processing efficiency. Utility Model Content

[0036] The present invention is described in detail below in conjunction with specific embodiments.

[0037] In the present utility model, unless otherwise clearly specified and limited, when terms such as "set on", "connected", and "connected" appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or connected through one or more intermediate media. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances. The directional words that appear in the present utility model are to better illustrate the characteristics of the features and the relationship between the features. It should be understood that when the placement direction of the present utility model changes, the characteristics of the features and the direction of the relationship between the features also change accordingly. Therefore, the directional words do not constitute an absolute limitation on the characteristics of the features and the relationship between the features in space, but only play a relative limitation role.

[0038] like Figures 1 to 16 As shown, the utility model provides a rapid welding device for tubular parts, including a welding gun 2 and a bracket 1, the welding gun 2 is installed on the bracket 1 through a movable component 3, a clamping seat 4 is provided on the bracket 1, a clamping assembly is provided on the clamping seat 4, the clamping assembly includes a clamp driving member 41, a differential case 42 and a clamping head component 43, the clamp driving member 41 and the differential case 42 are both installed on the clamping seat 4, a connecting hole 40 is provided on the clamping seat 4, and the clamp driving member 41 is linked to the clamping head component 43 to rotate through the differential case 42;

[0040] An electromagnetic coil 432 is disposed at the connecting hole 40 , and a magnetic column 433 is disposed on the sliding sleeve 434 .

[0041] Through the above design scheme, when it is necessary to quickly pick up and place parts, the electromagnetic coil 432 will generate a magnetic field after being energized. The magnetic column 433 will automatically approach the electromagnetic coil 432 under the attraction of the magnetic field, causing the sliding sleeve 434 to automatically slide backward. When the sliding sleeve 434 slides to a certain distance, the tensioning sleeve 436 will automatically open. The staff can take the opportunity to place the parts waiting to be welded in the tensioning sleeve 436. After the electromagnetic coil 432 is powered off, the sliding sleeve 434 will automatically reset under the action of the sliding elastic member 435, and the tensioning sleeve 436 will contract again to clamp the parts to ensure that the parts can be locked; when the parts are locked on the tensioning sleeve 436, the clamp driving member 41 drives the chuck component 43 to rotate slowly and uniformly through the differential box 42 to ensure that the parts can be evenly welded.

[0042] In this embodiment, a plurality of groups of J-shaped grooves 4300 are provided on the connection seat 430, and a projection 4363 corresponding to the J-shaped groove 4300 is provided on the tension sleeve 436, and the projection 4363 can slide into the J-shaped groove 4300 from the opening of the J-shaped groove 4300;

With the assistance of the gear and the gear tooth portion, the clamping seat 4 can be accurately controlled by the swing drive 52 to tilt the angle.

[0049] In this embodiment, the movable component 3 includes a lifting frame 31, a bogie 32, an extension frame 33 and an adjustment frame 36.

A rack is provided on the fixed frame 361, and the rack is meshed with the fine-tuning gear 363.

[0052] Through the above design scheme, the lifting frame 31 is used to adjust the height of the welding gun 2. When adjustment is needed, it is only necessary to rotate the fixing knob 300 to loosen the lifting frame 31 so that the lifting frame 31 can slide in the lifting seat 30. After adjusting to a suitable position, the fixing knob 300 is tightened to fix the lifting frame 31; the bogie 32 is used to adjust the rotation angle of the welding gun 2 so that the welding gun 2 is aligned with the parts clamped by the tensioning sleeve 436. A locking device is provided on the bogie 32, and the locking device can lock the bogie 32 to avoid accidental touching and causing it to turn and deflect during welding; in this embodiment, the locking device is a locking screw sleeve.
