A placing disk 110 is fixed at the top ends of the three guiding slide rods 109. The same number of steel pipe placing seats 114 as that of the extension plates 107 are fixedly arranged in a circular array on the upper surface of the placing disk 110. Steel pipes 3 can be placed on the steel pipe placing seats 114. A discharging electric cylinder 108 is fixed at the central position of the lower surface of the rotating disk 106. The end of the telescopic rod of the discharging electric cylinder 108 is fixed to the center of the placing disk 110, and is used to drive the placing disk 110 to move upward. A collecting cover 113 is arranged outside the placing disk 110. The collecting cover 113 is fixed on a base 112, and the support table 101 is also fixed on the base 112. A driving motor 102 is embedded in the support table 101. 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 inside the support table 101. The driving gear cylinder 104 is fixedly engaged with the rotating disk 106 and is used to drive the rotating disk 106 to rotate. A cam disk 105 is also fixedly installed on the support table 101. A plurality of convex blocks 111 are arranged in a circular and equidistant array on the upper surface of the cam disk 105.

[0021] The welding part includes a welding seat 201 fixedly fitted with an extension plate 107. Two symmetrically arranged welding support side plates 204 are fixedly installed on the welding seat 201. Horizontal sliding grooves 205 are arranged on both of the two welding support side plates 204. Sliding rotating shafts 217 are slidably fitted in the two sliding grooves 205. A downward pressing moving plate 210 is fixed between the two sliding rotating shafts 217. A superalloy sliding groove 212 is also fixedly installed between the two welding support side plates 204, and a steel plate 4 can be placed in the superalloy sliding groove 212. A support bar 214 is slidably arranged at the bottom of the superalloy sliding groove 212. A sliding rod 202 is fixedly installed at the bottom of the support bar 214. A return spring 215 is wound 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. A roller 203 that rolls with a bump 111 is rotatably installed at the bottom end of the sliding rod 202. A placement groove 213 is formed in the downward pressing moving plate 210 to facilitate the steel plate 4 to pass through the placement groove 213 and enter the superalloy sliding groove 212. A discharge groove 216 is also formed in the downward pressing moving plate 210 at the position of the placement groove 213 for separating the welded steel pipe 3. A counterweight 211 is fixed at one end of the downward pressing moving 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 gap groove is arranged in the middle of the limiting frame 206, and a pin rod 207 can be inserted and fitted in the gap groove. The pin rod 207 is fixedly fitted with the sliding rotating shaft 217. A pin 209 fixed to the welding support side plate 204 is arranged on the side of the limiting frame 206. The pin 209 and the sliding rotating shaft 217 are elastically connected through an elastic component 208. Bearing sleeves are arranged at the contact positions of the elastic component 208 with the pin 209 and the sliding rotating shaft 217.

[0022] The working principle of a multifunctional automatic welding device for stainless steel parts disclosed in the present invention is as follows: All the steel pipes 3 to be welded are placed on a steel pipe placement seat 114, and then the steel plate 4 to be butt - welded with the steel pipe 3 is inserted into the superalloy sliding groove 212 through the placement groove 213 (initially, the steel plate 4 does not press the support bar 214, but is only 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 completely stops rotating (welding is completed), the unloading electric cylinder 108 is activated. The telescopic rod of the unloading electric cylinder 108 drives the placement plate 110 to move upward. At this time, the placement plate 110 is moved to a position higher than the collection hood 113. In this process, the steel pipe 3 passes through the unloading chute 216, and at the same time, the steel plate 4 passes through the placement groove 213 (because the downward moving plate 210 has been reset). Then, the drive motor 102 is slowly started. The drive motor 102 drives the steel pipe 3 to rotate again. At this time, the steel pipe 3 slides out from the support strip 214 under the action of centrifugal force and thus falls onto the collection hood 113.
