Description

Technical Field

[0001] The present application relates to the technical field of welding and polishing equipment, and in particular to a welding and polishing device for a methylammonium pump casing. Background Art

[0002] In many industries such as chemical industry, methylammonium pump plays an extremely critical role. As its core component, the quality and processing accuracy of methylammonium pump casing directly affect the overall performance and service life of the pump. In the process of processing methylammonium pump casing, welding and polishing equipment is mostly required, which can ensure high-quality processing of pump casing, which directly provides a solid guarantee for the performance improvement and stable operation of methylammonium pump.

[0003] Before welding and polishing the methyl ammonium pump casing, most of the existing welding and polishing devices find it difficult to grind and remove impurities on the adjacent end faces of the methyl ammonium pump casing. The grinding and impurity removal work mostly relies on manual work by staff, which increases the investment in human resources. At the same time, the rust, oil stains and rough parts on the surface of the end faces that have not been grinded and removed will cause the fusion of the weld to deteriorate, and easily form welding defects such as cold welds and slag inclusions.

[0004] At the same time, it is difficult for existing welding and polishing devices to integrate multiple processing functions such as clamping, welding, grinding and polishing on the methyl ammonium pump casing on the same device, and it is often necessary to have multiple different devices to complete these processes separately. This results in a large footprint and high investment cost. At the same time, when processing the methyl ammonium pump casing, it is usually difficult to achieve a cycle of clamping, welding, grinding and polishing processes, which in turn limits the improvement of overall production efficiency. Summary of the invention

[0005] The present application aims to solve at least one of the technical problems existing in the prior art.

At the same time, by grinding the end face of the carboxyammonium pump casing, it can effectively remove the defects and impurities on the adjacent surfaces of the pump casing, so that the end face of the pump casing can reach the ideal roughness and flatness requirements, laying a solid foundation for the subsequent welding and polishing processes. At the same time, in the process of grinding the adjacent end faces, no additional intervention by the staff is required, which improves the processing quality of the carboxyammonium pump casing while reducing the investment in human resources.

[0058] like Fig.15 and Fig.16As shown, the power output mechanism 4 includes a positioning frame 401, the positioning frame 401 is fixedly connected to the outer wall of the front end of the connecting plate 103, the upper surface of the positioning frame 401 is fixedly connected to the third servo motor 402, the output end of the third servo motor 402 is fixedly connected to the long connecting rod 403, the front end and the rear end of the outer wall of the long connecting rod 403 are respectively sleeved with a transmission gear 404, the transmission gear 404 is fixedly connected to a circular connecting cylinder 405 at the edge of one end of the middle part of the long connecting rod 403, the outer wall of the circular connecting cylinder 405 away from the end of the transmission gear 404 is fixedly connected to an intermediate gear ring 406, the outer wall of the circular connecting cylinder 405 close to one end of the middle part of the long connecting rod 403 is rotatably connected to a swivel 407, and the outer wall of one side of the swivel 407 is fixedly connected to The special-shaped frame 408, the positioning plate 224 located at the upper end of the small convex plate 104 is fixedly connected to the lower end of the special-shaped frame 408. During the movement of the positioning plate 224, the special-shaped frame 408, the rotating ring 407, the circular connecting tube 405 and the transmission gear 404 are driven to move synchronously. During the welding and polishing of the pump casing, the transmission gear 404 and the large gear ring 317 are meshed with each other, and the middle gear ring 406 remains idle. During the grinding of the end face of the pump casing, the transmission gear 404 and the middle gear ring 406 are respectively meshed with the middle gear 229. The outer walls of the front and rear ends of the long connecting rod 403 are fixedly connected with multiple second clips 409. During the reciprocating movement of the transmission gear 404, the outer wall of the second clip 409 slides.

[0059] Specifically, the working principle of the methylammonium pump casing welding and polishing device is as follows: during the processing of the methylammonium pump, the first servo motor 106 is first started, and its output end drives the first bidirectional screw 107 to rotate. Since the first bidirectional screw 107 and the second bidirectional screw 108 are meshed and driven by the first bevel gear 109 and the second bevel gear 119, the second bidirectional screw 108 also rotates synchronously. At this time, the first slider 114 moves in the opposite direction along the screw, and the connecting block 117 at the upper end of the first slider 114 drives the clamping frame 118 to move, and the clamping plate 116 performs a linear motion under the guidance of the guide rail 115, thereby realizing the clamping or loosening operation of the methylammonium pump casing. When it is necessary to polish the two end faces of the clamped methylammonium pump, the small convex plate 1 04 and the large convex plate 105 will drive the methylammonium pump to move in opposite directions. At this time, the first long rotating rod 110 and the first short rotating rod 111 will respectively drive the first clamping strip 113 to move to the outside of the positioning cylinder 112, thereby playing a role in positioning and stabilizing transmission during the rotation of the screw. At this time, starting the second servo motor 201 can make the one-way long screw rod 202 rotate. At this time, the large slide plate 203 will drive the long tooth plate 204 to move horizontally to the left. At this time, the long tooth plate 204 will mesh with the driven gear 206 on the left during the horizontal movement, and the driven gear 206 will drive the one-way middle screw rod 205 to rotate. At this time, the second slider 207 will drive the fixed frame 208 to move upward, and the short tooth plate 209 at one end of the fixed frame 208 moves upward and is connected with the first A gear cylinder 211 is meshed to rotate the second short rotating rod 210, and the third bevel gear 212 in the middle of the second short rotating rod 210 is meshed with the fourth bevel gear 216 at the lower end of the second long rotating rod 213 to transmit power to the second long rotating rod 213, and the fourth bevel gear 216 in the middle of the second long rotating rod 213 is meshed with the fifth bevel gear 217 on the first transmission rod 214 to rotate the first transmission rod 214. At this time, the second transmission rod 215 can be rotated under the action of the first transmission wheel 218 and the lower toothed belt 221. At this time, the third bidirectional screw 219 can be rotated under the action of the second transmission wheel 220 and the upper toothed belt 221. When the third bidirectional screw 219 rotates, the third slider 222 and the fourth slider 223 at both ends thereof will move in opposite directions. The small convex plate 104 and the large convex plate 105 move in opposite directions, thereby separating the clamped pump casing. When the fixed frame 208 continues to move upward, the short tooth plate 209 cannot mesh with the first gear cylinder 211, and the upper parts of the small convex plate 104 and the large convex plate 105 are separated. The position of the methylammonium pump will be determined. At the same time, the positioning plate 224 at the upper end of the small convex plate 104 will drive the special-shaped frame 408 at the corresponding position to move synchronously. The special-shaped frame 408 will drive the rotating ring 407, the circular connecting cylinder 405, the transmission gear 404 and the intermediate gear ring 406 to move synchronously. When the fixed frame 208 continues to move upward, the assembly plate 225 will drive the grinding ring 226 to move upward. When the position of the grinding ring 226 is determined,The transmission gear 404 and the intermediate gear ring 406 at the corresponding position will mesh with the intermediate gear 229, and then the long connecting rod 403 can be rotated by starting the third servo motor 402. At this time, the transmission gear 404 and the intermediate gear ring 406 in the rotating process can make the small gear ring 227 drive the intermediate gear 229, the connecting ring frame 230 and the grinding pad 231 to rotate under the action of meshing with the intermediate gear 229, so as to realize the grinding of the adjacent end faces of the methylammonium pump housing. When the grinding of a group of methylammonium pump housings is completed, the second servo motor 201 is started in the reverse direction to reverse the one-way long screw rod 202, and the large slide plate 203 drives the long tooth plate 204 to move horizontally to the right, and the transmission components operate in the reverse direction, and the fixed frame 208 moves downward. At this time, the grinding circle 226 will first move in During the downward movement of the assembly plate 225, it moves to the lower part of the connecting plate 103. At this time, the short tooth plate 209 meshes with the first gear cylinder 211 again, causing the second short rotating rod 210 to reverse. Through the linkage of a series of bevel gears and the transmission rod, the third bidirectional screw 219 reverses, driving the positioning plate 224 to make the small convex plate 104 and the large convex plate 105 move toward each other, and re-clamp the pump housing. When the short tooth plate 209 drops to the top of the first gear cylinder 211, the second servo motor 201 stops rotating. At this time, the special-shaped frame 408 will also drive the round connecting cylinder 405 to return to its original position, and the transmission gear 404 will mesh with the large gear ring 317. Starting the third servo motor 402 again can make the long connecting rod 403 rotate again and start the welder 313. At this time, the large gear ring 317 in the rotation process The switching ring 311 and the welder 313 will be driven to operate and weld the pump casing. When the welding is completed and the pump casing needs to be polished, the second servo motor 201 is started again to make the large slide plate 203 continue to drive the long tooth plate 204 to move horizontally to the right. The short tooth plate 209 meshes with the second gear cylinder 302 during the downward movement. The one-way short lead screw 306 is rotated through the third long rotating rod 304 and the bevel gear transmission. The slide cylinder 309 drives the switching frame 310 and the switching ring 311 to move. The bayonet pin 314 is engaged with the slot 318 of the large gear ring 317 in the switching cover 316. The welder 313 is replaced by the grinder 312. At this time, the methylammonium pump to be processed is installed on the right end. At this time, the long tooth plate 204 on the other side moves to the right and meshes with the driven gear 20 6 mesh with each other and drive the one-way middle screw rod 205 to rotate. At this time, the pump casing that has been clamped at the right end will be separated again. At the same time, the transmission gear 404 and the middle gear ring 406 at the right end will mesh with the middle gear 229. Starting the third servo motor 402 can make the long connecting rod 403 at the right end rotate, driving the corresponding small gear ring 227, the connecting ring frame 230 and the grinding pad 231 to rotate, so as to grind the adjacent end faces of the newly installed methylammonium pump casing. At the same time, start the grinder 312 at the left end. At this time, the grinder 312 at the left end will polish and grind the previously welded pump casing under the cooperation of the transmission gear 404 and the large gear ring 317, and operate synchronously with the end face grinding mechanism 2 at the right end. The power comes from the third servo motor 402.When the grinding work on both ends is completed, the device can switch to the clamping and welding processes of the pump casing again, and the cycle can be repeated to achieve continuous and efficient processing of the methylammonium pump, greatly improving production efficiency and reducing production costs.
