Description

Technical Field

[0001] This invention relates to the field of casting processing technology, and in particular to a multi-stage submersible vertical pump casing casting processing equipment. Background Technology

[0002] In the field of casting processing technology, components with complex geometries, such as pump bodies and valve bodies, are widely used. After casting, these components typically have residual gating gates, flash, burrs, and uneven casting skin on their surface and interior. They must undergo finishing processes such as grinding and polishing to meet the requirements of dimensional accuracy, surface finish, and performance.

[0003] Grinding complex components like pump bodies still largely relies on manual labor or semi-automated equipment. In practice, several major technical challenges arise: First, due to the complex structure of pump bodies, which often contain multiple mounting interfaces, internal cavities, and flow channels in different directions, numerous grinding dead zones exist, especially at the junctions of the inner and outer walls of various openings and in narrow internal cavities. Conventional grinding tools struggle to reach these areas effectively, resulting in incomplete deburring and severely impacting product quality. Second, achieving stable and reliable clamping and fixing of irregularly shaped pump bodies during grinding is itself a challenge. Existing fixture designs often obstruct certain areas of the pump body to be ground, forcing operators to frequently disassemble, adjust, and re-clamp the workpiece, leading to inefficiency and introducing secondary positioning errors. Furthermore, grinding the inner and outer walls of openings, as well as the inner and outer surfaces of the pump body, typically requires changing different tools or performing the process multiple times, making simultaneous and efficient automated processing difficult and hindering overall production efficiency and processing consistency.

[0004] In the prior art, Chinese invention patent with publication number CN112405142A discloses a forming equipment for processing centrifugal pump casing. The cutting blade and grinding blade of this device can simultaneously bore and grind the casing. However, this device cannot effectively grind the joints at the openings, which greatly affects the processing efficiency of the casing. In addition, there are a large number of dead corners that cannot be effectively processed and require secondary manual processing. Summary of the Invention

[0033] Working principle: When working, the pump body 102 is placed on the base 101. The electric cylinder 112 is started, which drives the clamping plate 113 to rise. The clamping plate 113 drives the support plate 114 to align with the bottom of the pump body 102. The electric cylinder 215 is started, which drives the two sets of support plates 114 to move away from each other. The support plates 114 clamp the bottom of the pump body 102, thus fixing the pump body 102.

[0034] Then, motor 107 is started, which drives lead screw 116 to rotate. Lead screw 116 drives mounting bracket 104 to slide on base 101. Mounting bracket 104 drives wire roller 106 to align with multiple sets of mounting holes 117. Then, electric cylinder 112 is started, which drives pump body 102 to rise. At this time, wire roller 106 is inserted into mounting hole 117. Motor 105 is started, which drives wire roller 106 to rotate. Wire roller 106 grinds the burrs in mounting hole 117. After grinding is completed, drive clamping plate 113 and mounting bracket 104 to reset.

[0035] When grinding the inner and outer walls of opening 110 and opening 111, motor 3 108 is started. Motor 3 108 drives lead screw 109 to rotate, and lead screw 109 drives the two sets of mounting brackets 201 to move closer to each other. Mounting bracket 201 drives wire roller 206 to insert into opening 110 and opening 211. Electric cylinder 3 210 is activated, causing mounting bracket 3 207 to slide on mounting post 1 205. Mounting bracket 3 207 moves wire roller 4 209, adjusting its position to ensure it completely covers the outer wall of opening 110. Simultaneously, mounting bracket 3 207 moves grinding bracket 1 211. When grinding bracket 1 211 brings wire roller 3 208 into contact with pump body 102, grinding bracket 1 211 compresses spring 213, ensuring complete contact between wire roller 3 208 and pump body 102. During grinding, motor 4 203 is activated, driving mounting post 1... 205. Wire roller 206 and mounting frame 3 207 rotate. Wire roller 206 grinds the inner walls of opening 110 and opening 211. Mounting frame 3 207 drives wire roller 3 208 and wire roller 4 209 to rotate along the axis of mounting column 1 205. Due to the setting of spring 213, when mounting frame 3 207 adjusts the position of wire roller 4 209, wire roller 3 208 is always in contact with pump body 102. At the same time, motor 5 212 and motor 11 start working. Motor 5 212 drives wire roller 3 208 to rotate. Wire roller 3 208 grinds the connection between opening 110, opening 211 and pump body 102. Wire roller 4 209 grinds the outer walls of opening 110 and opening 211.

The lead screw 4 318 drives the adjusting ring 306 to slide on the mounting column 2 302. The adjusting ring 306 drives the grinding frame 3 319 to slide inside the mounting column 2 302 through the connecting rod 322. The grinding frame 3 319 drives the steel wire roller 6 320 to fit against the inner wall of the pump body 102.

[0039] Start motor 8 313, which drives steel wire roller 5 310 to rotate. Steel wire roller 5 310 polishes the outer wall of pump body 102. Start motor 10 321, which drives steel wire roller 6 320 to rotate. Steel wire roller 6 320 polishes the inner wall of pump body 102. At the same time, start adsorption plate 1 311 and adsorption plate 2 314. The debris generated when adsorption plate 1 311 and adsorption plate 2 314 polish the inner and outer walls of pump body 102 is collected into recovery box 2 312.

[0040] During the operation of wire roller five 310 and wire roller six 320, motor seven 307 is started. Motor seven 307 drives gear one 308 to rotate, gear one 308 drives gear two 309 to rotate, gear two 309 drives mounting column two 302 to rotate, and mounting column two 302 drives grinding frame three 319 and grinding frame two 305 to rotate along the axis of mounting column two 302. Grinding frame three 319 and sandpaper 323 at the lower end of mounting column two 302 grind the bottom of the inner wall of pump body 102.

[0041] When the second grinding frame 305 moves to the positions of the first opening 110 and the second opening 111, the fourth electric cylinder 315 is activated. The fourth electric cylinder 315 drives the second grinding frame 305 to move away from the pump body 102. After passing the first opening 110 and the second opening 111, the fourth electric cylinder 315 drives the second grinding frame 305 to reset. The second grinding frame 305 drives the fifth wire roller 310 to continue to be in contact with the outer wall of the pump body 102.
