Description

Technical Field

[0001] The invention relates to a welding device, in particular to a welding device for producing and processing stainless steel clamps. Background Art

[0002] A clamp is a connection device for connecting grooved pipes, valves and pipe fittings. It is used to tighten quick connectors. There are various types and wide applications, especially stainless steel clamps. The clamp generally includes a ring band, with two ears at both ends of the ring band. A threaded shaft passes through the two ears, and a nut is set at one or both ends of the threaded shaft. By tightening the nut, the two ears are abutted, thereby clamping the clamp.

[0003] In order to enhance the connection stability of the clamp, an inner liner is usually added to the clamp during the production and processing of the stainless steel clamp, and the inner liner needs to be welded to the inner wall of the clamp body. However, the stainless steel clamp welding device in the prior art cannot quickly complete the positioning and removal of the stainless steel clamp, resulting in stagnation of work efficiency. After welding, welding slag is likely to remain on the work surface, which will affect the quality of subsequent welding operations if it is not cleaned in time.

[0051] Specifically, the reciprocating sliding mechanism includes a lubrication hole 301, a side port 302 and an exhaust fan mounting seat 303. A lubrication hole 301 is opened on the top of the cross beam 3, and a side port 302 leading to the lubrication hole 301 is opened on the side of the cross beam 3. The exhaust fan mounting seat 303 is slidably connected in the lubrication hole 301, and the exhaust fan mounting seat 303 slides through the side port 302. The dust suction mechanism 4 is installed on the exhaust fan mounting seat 303, so that the position of the dust suction mechanism 4 can be changed for use and maintenance.

[0052] Specifically, the dust suction mechanism 4 includes an exhaust fan body 401, a slag suction pipe 402, an output pipe 403 and a slag collecting bag 404. The exhaust fan body 401 is fixedly installed on the top of the exhaust fan mounting base 303. The slag suction pipe 402 and the output pipe 403 are fixedly connected to the exhaust fan body 401.

[0054] The specific implementation method of this embodiment is: the stainless steel clamp original is placed on the support 201 on the clamp positioning plate 2, and two stainless steel clamp originals are placed on each clamp positioning plate 2, such as Figure 1 , 3 As shown, two stainless steel clamp components are placed symmetrically, and the liner is placed in the inner ring of the stainless steel clamp component.

In preparation for subsequent welding, the external welding device is installed on the welding device installation plate 5, so that the external welding device completes the welding of the stainless steel clamp component and the liner.

[0055] After welding is completed, the servo motor 107 works to rotate the linear screw 103. Under the linkage of the pulley 104 and the transmission belt 105, the two linear screws 1003 rotate together, and then the two positioning plate mounting seats 102 move in the direction close to the cross beam 3, that is, the two clamp positioning plates 2 move at the same time, until the clamp positioning plates 2 move to the bottom of the cross beam 3. At this time, all the extrusion heads 204 are separated from the blocking bars 206. Under the elastic force of the compression spring 205, the extrusion head 204 drives the push rod 202 and the clamp jaws 203 to slide in the direction away from the stainless steel clamp original, thereby automatically releasing the fixation of the stainless steel clamp original. When the clamp positioning plate 2 is reset, the positioning and clamping of the stainless steel clamp original can be automatically completed.

[0056] During the process of the clamp positioning plate 2 moving to the bottom of the cross beam 3, the linear screw 103 can drive the follower slider 601 to move along the linear slide rail 101, and the follower slider 601 moves in the direction away from the cross beam 3. Driven by the connecting rod 603, the exhaust fan mounting seat 303 slides toward the middle of the lubrication hole 301 until the exhaust fan body 401 moves to the top of the clamp positioning plate 2. The exhaust fan body 401 works to extract the welding slag and collect it in the slag collecting bag 404 to keep the clamp positioning plate 2 clean, thereby providing a guarantee for the quality of subsequent welding.
