Technical Field
The utility model belongs to the technical field of pump class machining, what relate to is a horizontal multistage centrifugal pump inhales section, spits section pump foot hole drilling equipment.
Background
At present, in the technical field of pump machining, particularly hole machining of pump foot holes of a suction section and a discharge section of a horizontal multistage centrifugal pump, a manual operation method is still used, and traditional bench workers are used for marking and drilling holes. The traditional marking-off positioning drilling machining needs skilled operators to work, and has the defects of low precision, high production cost, low efficiency and the like. Meanwhile, the interchangeability is poor, and the quality is difficult to reach the unified standard.
Disclosure of Invention
In order to solve the defects of the prior art, the utility model aims at providing a horizontal multistage centrifugal pump inhales section, spits section pump foot hole drilling equipment. The device is used for drilling, the size is accurate and high, the interchangeability is good, the cost is low, and the production efficiency is improved.
Realize the utility model discloses a technical scheme that the purpose adopted is: a horizontal multistage centrifugal pump suction section and discharge section pump foot hole drilling device comprises a drilling template, a fastening screw, a positioning plate, a clamping connecting rod, a supporting plate, a clamping nut, a drilling template sleeve and a positioning jackscrew; the upper part of the drilling template is provided with two drilling template sleeves and two positioning jackscrews, and the lower part of the drilling template is vertically fixed on the side surface of the positioning plate by fastening screws; the center of the positioning plate is vertically screwed with a clamping connecting rod, the other end of the clamping connecting rod is sleeved with a supporting plate and a clamping nut, and the center of the upper plane of the positioning plate is provided with a positioning boss.
The hole pitch of the two drill jig sleeves on the drill jig plate is equal to the hole pitch of the pump foot hole of the suction section or the discharge section, and the vertical height of the center of the drill jig sleeve hole is the sum of the thickness of the positioning plate and the vertical distance from the center of the pump foot hole of the suction section or the discharge section to the reference plane of the suction section or the discharge section.
When the positioning plate works, the upper plane of the positioning boss on the positioning plate is attached to the reference plane of the suction section or the discharge section, and the outer diameter of the positioning boss is matched and positioned with the inner diameter of the notch on the suction section or the discharge section; a clamping connecting rod on the positioning plate penetrates through the segment body, a supporting plate is sleeved on the end part of the clamping connecting rod, and a clamping nut is screwed up to fix the drilling device on the segment body; the positioning jackscrew on the drilling template is tightly propped against the bottom plane of the pump foot of the suction section or the discharge section, so that the parallelism and the strength of the drilling template and the bottom plane of the pump foot are ensured; and a drill bit on the drilling machine drills through the drill jig sleeve.
The utility model has the advantages that: because the utility model discloses horizontal multistage centrifugal pump inhales the section, spits the pump foot spot facing work of section and has adopted drilling equipment, has solved the not enough of traditional pincers worker marking off drilling, and the hole size that drills is accurate high, and interchangeability is good to reduction in production cost, improved production efficiency.
