Description

Technical Field

[0001] The present invention relates to the technical field of special lathes, in particular to a lathe for processing water pump casings. Background Art

[0002] As a key component in fluid delivery systems, the machining accuracy of water pump casings directly impacts the pump's sealing performance and operating efficiency. Conventional water pump casings are typically machined using general-purpose lathes. However, due to the complex structure of the pump casing, particularly those with irregular feet or slats, the pump casing is susceptible to vibration during high-speed rotation due to center of gravity shifts, resulting in increased surface roughness and even dimensional deviations. Furthermore, traditional clamping methods struggle to quickly position and secure pump casings of varying specifications, and can easily cause deformation due to uneven clamping force, impacting the quality of the finished product. Prior art lathes employ multi-axis synchronous drives or hydraulic clamping mechanisms to improve machining stability, but these still present several drawbacks. The presence of the feet creates significant dynamic imbalance during rotation, and existing equipment lacks real-time counterweight adjustment, making it difficult to effectively suppress vibration. Traditional three-jaw chucks or custom fixtures require manual adjustment, making them unsuitable for the rapid switching of casings required for mass production. Furthermore, the loading and unloading and machining processes rely on manual intervention, making continuous operation difficult. Therefore, a specialized lathe for water pump casings with dynamic counterweight adjustment, adaptive internal support clamping, and automated coordinated control is urgently needed to address these technical issues. Summary of the Invention

[0007] When in use, the water pump casing is placed on the supporting seat, and the docking motor drives the output wheel and the half-tooth gear to rotate. When the half-tooth gear meshes with the lower intermittent gear, the half-tooth gear does not mesh with the upper intermittent gear, and the lower intermittent gear drives the inner long shaft and the end gear to rotate. The end gear drives the screw gear and the two-way screw rod to rotate through the vertical transmission belt, and the two-way screw rod drives the slide seat to slide inward through the inner convex ball, so that the outer sleeve is sleeved on the outside of the water pump casing, and the base foot of the water pump casing contacts the push plate, pushing the push plate to slide along the outer sleeve, and driving the counterweight to slide inward along the outer sleeve through the side rotating rod, thereby adjusting the position of the counterweight block at the position of the base foot of the water pump casing, so that the position of the counterweight block is closer to the center of the circle of the outer sleeve than the other three counterweight blocks, thereby adjusting the center of gravity of the outer sleeve and the water pump casing as a whole, so that the outer sleeve drives the water pump casing to rotate more smoothly, reducing the vibration generated when the water pump casing rotates.

[0011] Furthermore, a turning tool electric cylinder is fixedly mounted on the frame, and a turning tool is fixedly mounted on the output end of the turning tool electric cylinder.

[0012] When the outer sleeve reaches the outside of the water pump housing, the half-tooth gear disengages from the lower intermittent gear, and the half-tooth gear starts to mesh with the upper intermittent gear. The half-tooth gear drives the upper intermittent gear and the gear column to rotate, and the gear column drives the stud gear and the two-way threaded column to rotate. The two-way threaded column moves toward the water pump housing under the action of the side convex ball, and the stud gear keeps meshing with the gear column. The inner rotating support cylinder is inserted into the water pump housing. When the inner push column contacts the inner wall of the water pump housing, the two-way threaded column continues to move toward the water pump housing, causing the inner push column to slide along the inner sleeve, and the inner spring is compressed, and the cooperation between the conical surface of the cone and the supporting slope drives the inner support block to move outward. The support spring is compressed, and the inner wall of the water pump housing is tightened by the inner support block. When the two-way After the threaded column moves to the innermost side, the inner support block tightens the inner wall of the water pump housing, the inner rotating gear meshes with the rotating docking gear, the rotating motor drives the drive wheel to rotate, and drives the right rotating gear, outer rotating shaft, input gear and left rotating gear to rotate through the horizontal transmission belt. The right rotating gear drives the rotating docking gear to rotate through the rotating transmission belt, and drives the inner rotating gear and the inner rotating support cylinder to rotate, thereby driving the water pump housing to rotate together through the inner support block, and the inner rotating column rotates in the two-way threaded column. At the same time, the left rotating gear drives the upper transmission gear to rotate through the rotating transmission belt, and the upper transmission gear drives the rotating column gear, outer rotating column and outer sleeve to rotate.

[0015] The output wheel rotates through the V-belt to drive the lifting gear and the two-way threaded rod to rotate. The rotation of the two-way threaded rod drives the internal threaded seat to slide along the frame, and the lifting seat is driven up and down by the lifting rod.

[0044] The working principle of a lathe for processing a water pump casing disclosed in the present invention is as follows: when in use, the water pump casing 4 is placed on the supporting seat 309, and the docking motor 301 drives the output wheel 302 and the half-tooth gear 303 to rotate. The output wheel 302 rotates and drives the supporting gear 306 and the two-way threaded rod 305 to rotate through the V-belt 304. The two-way threaded rod 305 rotates and drives the internal threaded seat 307 to slide along the frame 101, and drives the supporting seat 309 to rise and fall through the supporting rod 308. When the outer sleeve 105 reaches the outside of the water pump casing 4, the supporting seat 309 is just at the highest point. When the half-tooth gear 303 is engaged with the lower intermittent gear 121, the half-tooth gear 303 is not engaged with the upper intermittent gear 203. The lower intermittent gear 121 drives the inner long shaft 107 and the end gear 108 to rotate. The end gear 108 is driven by the vertical The transmission belt 109 drives the screw gear 106 and the two-way screw rod 103 to rotate.

The half-tooth gear 303 drives the upper intermittent gear 203 and the gear column 201 to rotate, and the gear column 201 drives the stud gear 204 and the two-way threaded column 202 to rotate.

When the inner push column 212 contacts the inner wall of the water pump housing 4, the two-way threaded column 202 continues to move toward the water pump housing 4, causing the inner push column 212 to slide along the inner sleeve 217, and the inner spring 218 is compressed. Through the cooperation of the conical surface of the cone 213 and the supporting slope 216, the inner support block 214 is driven to move outward, and the support spring 215 is compressed. The water pump is pressed against the inner support block 214. The inner wall of the housing 4 is tightened. When the two-way threaded column 202 moves to the innermost side, the inner support block 214 tightens the inner wall of the water pump housing 4, and the inner rotating gear 205 engages with the rotating docking gear 210. The rotating motor 310 drives the driving wheel 311 to rotate, and drives the right rotating gear 120, the outer rotating shaft 110, the input gear 123 and the left rotating gear 111 to rotate through the horizontal transmission belt 312. The right rotating gear 120 drives the rotating docking gear 210 to rotate through the rotating transmission belt 313, driving the inner rotating gear 205 and The inner rotating support cylinder 208 rotates, thereby driving the water pump housing 4 to rotate together through the inner support block 214. The inner rotating column 211 rotates within the two-way threaded column 202. At the same time, the left rotating gear 111 drives the upper transmission gear 112 to rotate via the rotating transmission belt 114. The upper transmission gear 112 drives the rotating column gear 113, the outer rotating column 104, and the outer sleeve 105 to rotate. The rolling ball 115 reduces friction, and the turning tool electric cylinder 206 extends, driving the turning tool 207 to extend, and the turning tool 207 performs turning processing on the water pump housing 4.
