A driving motor 102 is embedded in the support platform 101, and a driving gear 103 is fixedly installed on the output shaft of the driving motor 102. A driving gear cylinder 104 is also rotatably installed on the inner side of the support platform 101, and the driving gear cylinder 104 is fixedly matched with the rotating disk 106 to drive the rotating disk 106 to rotate. A cam disk 105 is also fixedly installed on the support platform 101, and a plurality of protrusions 111 are arranged in a circular equidistant array on the upper surface of the cam disk 105.

[0021] The welding part includes a welding seat 201 fixedly matched with the extension plate 107, and two symmetrically arranged welding support side plates 204 are fixedly installed on the welding seat 201. The two welding support side plates 204 are both provided with horizontally arranged sliding grooves 205, and the two sliding grooves 205 are both slidably provided with sliding shafts 217. A downward pressing moving plate 210 is fixed between the two sliding shafts 217. A high-temperature alloy sliding groove 212 is also fixedly installed between the two welding support side plates 204, and the steel plate 4 can be placed in the high-temperature alloy sliding groove 212. A support bar 214 is slidably provided at the bottom of the high-temperature alloy sliding groove 212, and a sliding rod 202 is fixedly installed at the bottom of the support bar 214. A return spring 215 is arranged around the sliding rod 202, and both ends of the return spring 215 are fixed to the support bar 214 and the welding seat 201. The bottom end of the sliding rod 202 is rotatably provided with a roller 203 that cooperates with the rolling cam of the protrusion 111. The pressing movable plate 210 is provided with an insertion groove 213, which is convenient for the steel plate 4 to pass through the insertion groove 213 and enter the high-temperature alloy sliding groove 212. The pressing movable plate 210 is also provided with a discharge groove 216 at the position of the insertion groove 213, which is used to separate the welded steel pipe 3. A counterweight 211 is fixed to the end of the pressing movable plate 210 away from the discharge groove 216. A limiting frame 206 is fixed at the position of the sliding groove 205 on the welding support side plate 204. A slit groove is provided in the middle of the limiting frame 206. The slit groove can be plugged into a latch rod 207. The latch rod 207 is fixedly matched with the sliding shaft 217. A pin 209 fixed to the welding support side plate 204 is provided on the side of the limiting frame 206. The pin 209 and the sliding shaft 217 are elastically connected through an elastic component 208. The contact positions of the elastic component 208 , the pin 209 and the sliding shaft 217 are all provided with bearing sleeves.

[0022] The working principle of the multifunctional stainless steel automatic welding equipment disclosed in the present invention is as follows: all steel pipes 3 that need to be welded are placed on the steel pipe placement seat 114, and then the steel plate 4 that needs to be connected with the steel pipe 3 is inserted into the high-temperature conductive alloy sliding groove 212 through the insertion groove 213 (at the beginning, the steel plate 4 does not squeeze the support bar 214, but is just placed on the support bar 214).

[0023] The drive motor 102 is started, and the output shaft of the drive motor 102 drives the drive gear 103 to rotate, the drive gear 103 drives the drive gear cylinder 104 to rotate, the drive gear cylinder 104 drives the rotating disk 106 to rotate, and the rotating disk 106 drives the placement disk 110 and the extension plate 107 to rotate, and at this time, the steel pipe 3 on the placement disk 110 and the steel plate 4 on the extension plate 107 rotate synchronously. When the steel pipe 3 rotates, it will be squeezed by the centrifugal force to squeeze the steel plate 4, so there is pressure between the steel pipe 3 and the steel plate 4 (the weight of the steel pipe 3 needs to be within a reasonable range, and the centrifugal force on the steel pipe 3 will not crush the steel plate 4 and prevent it from moving), and at the same time, the sliding rod 202 in the welding part will also rotate, and the roller 203 at the bottom of the sliding rod 202 will continuously contact the protrusion 111, so as to realize the reciprocating motion of the sliding rod 202.

[0024] At the same time, when the welding part rotates, the pressing movable plate 210 and the counterweight 211 will also move outward under the action of centrifugal force, and the sliding shaft 217 on the pressing movable plate 210 will slide in the sliding groove 205. Due to the restriction of the slot groove of the limiting frame 206 on the latch rod 207, the pressing movable plate 210 will not swing at this time. When the latch rod 207 is pulled out of the slot groove of the limiting frame 206, it means that the pressing movable plate 210 moves a short distance outward (at the same time the elastic component 208 is stretched). At this time, the insertion groove 217 on the pressing movable plate 210 is 3 will be offset from the steel plate 4, and under the action of the counterweight 211, the downward pressing movable plate 210 will swing around the sliding shaft 217, so that the downward pressing movable plate 210 applies a downward pressure to the steel plate 4. At this time, the steel plate 4 will apply pressure to the support bar 214, and the return spring 215 will be compressed. With the reciprocating motion of the upper sliding rod 202, the steel plate 4 will reciprocate in the high-temperature alloy sliding groove 212. At this time, high-speed friction will occur between the steel pipe 3 and the steel plate 4, so that the contact surface of the steel pipe 3 and the steel plate 4 will generate high temperature, and the two will be melted and connected together.

[0025] Before the steel pipe 3 and the steel plate 4 are completely welded, the driving motor 102 is stopped, and the steel pipe 3 and the steel plate 4 will gradually stop rotating, so the centrifugal force will gradually disappear. At the same time, the downward moving plate 210 will also be reset under the action of the elastic component 208, and the steel plate 4 will also rebound and reset under the action of the reset spring 215, so that the roller 203 will no longer be in contact with the protrusion 111 continuously, so the steel plate 4 will no longer reciprocate, and the steel plate 4 and the steel pipe 3 will be relatively still until the welded molten connection cools and solidifies. At the same time, the latch rod 207 will be reinserted into the slit groove of the limiting frame 206 (the slit groove of the limiting frame 206 is provided with a chamfer to guide the latch rod 207 into the slit groove, and the latch rod 207 is always located at the limiting frame 206 completely separated).

[0026] When the downward moving plate 210 stops rotating completely (welding is completed), the unloading electric cylinder 108 is started, and the telescopic rod of the unloading electric cylinder 108 drives the placing plate 110 to move upward. At this time, the placing plate 110 is moved to a position higher than the collecting cover 113. During this process, the steel pipe 3 passes through the unloading groove 216, and the steel plate 4 passes through the placing groove 213 (because the downward moving plate 210 is reset). Then, the driving motor 102 is slowly started, and the driving motor 102 drives the steel pipe 3 to rotate. At this time, the steel pipe 3 will slide out from the support bar 214 under the action of centrifugal force, and fall onto the collecting cover 113.
