Description

Technical Field

[0001] The invention relates to the field of welding and casting, in particular to a plasma cladding welding device for eye plates and cutting rings of pump trucks. Background Art

[0002] The eye plate of a pump truck, also known as the eye plate cutting ring, is one of the important accessories of a concrete pump truck. Its main function is to ensure the sealing of concrete during pumping, preventing leakage, thereby ensuring pumping efficiency and construction quality. The cutting ring has a circular shape, and the eye plate of the pump truck has a double circular shape. The main function of this device is to weld and splice the eye ring and cutting ring of the pump truck, improving the production efficiency and quality of mechanical parts.

[0003] The existing Chinese patent, with the announcement number CN216370869U, discloses a pump truck boom side panel assembly welding workstation, which belongs to welding equipment. A welding robot is slidably mounted on a three-axis gantry, and an assembly tool is provided on one side of the three-axis gantry. The assembly tool includes a tool body with a slide rail. A front linear module, a tool assembly, and a rear linear module are slidably mounted on the tool body slide rail. The tool assembly includes a slide slidably mounted on the tool body slide rail. A joint forming platform is mounted on the slide in a liftable manner. The joint forming platform is provided with a sink groove, with a pair of positioning blocks and a pair of clamping assemblies mounted on either side of the sink groove. This technical solution uses an electric tool to adjust the tool key into place, which can meet the welding requirements of workpieces of different lengths. The use of a single-sided welding and double-sided forming method and a pneumatic clamping mechanism reduces the labor intensity of workers and improves production efficiency. The tool assembly and linear module can be adapted to various types of workpieces through electric adjustment.

[0004] However, the welding workstation of the boom side plate assembly of the pump truck still has the following defects:

[0005] 1. The eye plates and cutting rings on the pump truck have high processing costs and cannot be processed by batch surfacing. In addition, their special shapes make it difficult for the robotic arm to pick up the circular eye plates and cutting rings when they lie flat on the conveyor belt during transportation. When the circular cutting rings are transported on the conveyor belt, they will roll during transportation and fall from the work surface. In addition, the heat on the surface of the metal parts after surfacing is not dissipated. The concentrated stacking of metal parts will cause the welding points on the surface of the metal parts to stick together. The changes in the organization and performance of the heat-affected zone after welding will lead to the degradation of the overall performance of the structure. Plastic deformation and adhesion are prone to occur due to heat. After cooling, these deformations of the eye plates and cutting rings of the pump truck cannot be completely restored and residual stress will be formed.

[0006] 2. In addition, during the processing of the annular pump truck eye plate and cutting ring, the processing head needs to circle around the surface of the annular metal part. Summary of the Invention

In addition, cooling can reduce the changes in the organization and performance of the heat affected zone after welding, which leads to the degradation of the overall performance of the structure, and avoids the problem of plastic deformation and adhesion of the pump truck eye plate template and cutting ring template due to heat. Because the pump truck eye plate template and cutting ring template cannot be fully restored due to plastic deformation and adhesion after cooling, and residual stress will be formed.

[0021] Secondly, the supporting flip structure enables the processing head to circle around the surface of the annular pump truck eye plate template and the cutting ring template during the processing. The function of the supporting flip structure is to adjust the angles of the second support plate and the first support plate supported at the bottom of the pump truck eye plate template according to the processing position, so that the welding pump truck eye plate template can be surrounded. When the telescopic motor retracts, the second support plate and the first support plate flip to the required position, and the supporting side plate drives the conveyor belt to tilt, and the debris dropped during the weld is taken up by the main transmission crawler.

[0060] The top of the material receiving claw 416 is provided with a material receiving trough 8, and the bottom end of the material receiving claw 416 is hingedly connected to the third hinged rod 409 on the side away from the second hinged rod 408, and the flip rod 413 is hingedly installed with a material transfer hopper 415 on the side close to the material receiving claw 416, and the material transfer hopper 415 is in the shape of a triangular bucket. The flip rod 413 drives the material transfer hopper 415 to receive the pump truck eye plate template 6 transported by the material receiving claw 416.

[0061] The discharge end of the transition transport structure 4 is equipped with a material receiving box 5, and then the flip rod 413 drives the material transfer hopper 415 to flip, and the pump truck eye plate template 6 is transported into the material receiving box 5. By transporting the pump truck eye plate template 6 twice, the pump truck eye plate template 6 is transferred and the newly welded pump truck eye plate template 6 is cooled by transferring the pump truck eye plate template 6.

[0062] By transporting the pump truck eye plate template 6 through the material receiving claw 416 and the material transfer hopper 415, the pump truck eye plate template 6 can be automatically transported after the pump truck eye plate template 6 is processed and welded, so as to avoid the annular pump truck eye plate template 6 from falling from the work table during the transportation process, and the heat on the surface of the just welded pump truck eye plate has not been dissipated, and concentrated stacking will cause the welding points on the surface of the pump truck eye plate to stick together, and the stacked pump truck eye plates are easy to fall from the transport platform during the vibration of transportation. In addition, cooling can reduce the changes in the organization and performance of the heat affected zone after welding, which may cause the formation of The overall performance of the structure is degraded, and the problem of plastic deformation and adhesion of the material due to heat is avoided. These deformations cannot be fully restored after cooling, and residual stress will be formed. The external transfer of the pump truck eye plate template 6 twice can make the pump truck eye plate template 6 welded by the high-temperature welding head 314 cool down as soon as possible, and the method of transporting each group of pump truck eye plate templates 6 separately during transportation makes the transportation process of the pump truck eye plate template 6 more stable, avoiding adhesion during the transportation of the pump truck eye plate template 6 that has just been welded, and finally put them into the material receiving box 5 for centralized storage.

[0063] Working principle: First, the rotating motor 417 is started by an external power supply, and the rotating motor 417 drives the transmission roller 404 to rotate. The transmission roller 404 rotates and drives the triangular transmission rod 410 to rotate by driving the third hinge point 420. The third hinge point 420 pulls the second hinge rod 408 to drive the material receiving claw 416 to move. The function of the third hinge rod 409 is to assist the material receiving claw 416 to move. At the same time, when the triangular transmission rod 410 moves around the transmission roller 404, the triangular transmission rod 410 drives the flip rod 410 through the first hinge point 418. 3 movement, the flip rod 413 drives the material transfer hopper 415 to catch the pump truck eye plate template 6 delivered by the material receiving claw 416, and then the flip rod 413 drives the material transfer hopper 415 to flip, and delivers the pump truck eye plate template 6 to the material receiving box 5. By transporting the pump truck eye plate template 6 twice, the pump truck eye plate template 6 is transferred and the newly welded pump truck eye plate template 6 is cooled by transferring the pump truck eye plate template 6. This working principle demonstrates the transportation process of the double-ring pump truck eye plate template 6, and the single-ring cutting ring template 7 is the same as above.

[0064] Then, the transmission motor 302 is started by an external power supply, and the transmission motor 302 drives the first transmission roller 304 to rotate. The first transmission roller 304 drives the transmission toothed belt 305 to move through meshing transmission. The function of the protective shell 303 is to prevent dust. Then the transmission toothed belt 305 drives the connecting piece 307 to move, thereby horizontally moving the distance between the high-temperature welding head 314 and the welding point on the pump truck eye plate template 6. The external power supply starts the moving motor 308, and the moving motor 308 drives the transmission screw 309 to rotate. The transmission screw 309 drives the moving slider 310 to move. The moving slider 310 drives the adapter 311 to rise and fall, and further drives the magnetic slide rail 312 to rise and fall, thereby vertically moving the distance between the high-temperature welding head 314 and the welding point on the pump truck eye plate template 6. After the magnetic slide rail 312 is energized, the magnetic slider 313 is controlled to rise and fall by magnetic force, and the position of the magnetically controlled high-temperature welding head 314 is more precise.

[0065] Finally, the external power supply starts the telescopic motor 202 to telescope and drive the articulated fork 203 to move, and the articulated fork 203 drives the hinged member 204 to rotate around the first fixed rod 205. When the articulated member 204 rotates, it drives the first connecting rod 206 and the second connecting rod 207 to move. The first connecting rod 206 drives the second triangular member 227 to flip around the fourth fixed rod 214. The flipping of the second triangular member 227 will drive the second movable top member 215 to move, and the second movable top member 215 will drive the third fixed rod 211 at the top to rotate. The rotation of the third fixed rod 211 will drive the second supporting plate 213 to flip along with the third fixed rod 211. The second connecting rod 207 on the other side drives the first triangular member 208 to flip around the second fixed rod 209. The flipping of the first triangular member 208 will drive the first movable top member 210 to move. The first movable top member 210 will drive the fifth fixed rod 226 at the top to rotate. The rotation of the fifth fixed rod 226 will drive the first supporting plate 212 to flip along with the fifth fixed rod 226.

[0066] In addition, when the telescopic motor 202 retracts, the second support plate 213 and the first support plate 212 will be flipped to the required position through transmission, and then the articulated fork 203 will drive the connecting rib 218 to flip, and the supporting side plate 219 with the connecting rib 218 will rotate around the conveying rod 222, and the connecting strut 220 will slide within the range of the limiting track 224. The supporting side plate 219 will drive the conveyor belt to tilt, and the conveying motor 223 will drive the conveying rod 222 to rotate, and the conveying rod 222 will drive the transmission roller 216, the rotating roller 221 and the side conveying crawler 217 to transmit, thereby driving the main conveying crawler 225 to receive the debris dropped during the weld.
