Embodiment Construction

[0019] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] refer to figure 1 , the separator consists of bearing housing 11 and support plate 13. The bearing housing 11 is provided with an oil hole 14 and its oil groove 15; the bearing housing 11 is rough machined in one piece after casting, the oil hole 14 is drilled, and the oil groove 15 is formed by a lathe. As, the inner hole of the bearing seat 11 is rough turned, leaving a small amount of machining allowance. The support plate 13 is cut by a numerical control cutting machine to make a welding groove; each corresponding set of bearing housing 11 is welded together with the support plate 13 to form a set of partitions, and the deformation is adjusted after welding. The entire frame is composed of multiple partitions, and connecting plates are welded between adjacent partitions. The two partitions on both sides are similar in structure an...

Abstract

The invention discloses a manufacture method of a multi-baffle large-aperture box frame. The method comprises the steps of firstly, reliably connecting positioning bases and limiting blocks, ensuring that side surfaces of the positioning bases and the limiting blocks are adhered, loading the positioning bases and the limiting blocks into baffle inner holes integrally, then welding the limiting blocks with baffle bearing seats in a spot welding way, secondly, establishing lines on a combined platform to determine positions of all baffles, ensuring that a core shaft penetrates through all the positioning bases, fixing the positions of the positioning bases separately through positioning pins, connecting the positioning bases with the core shaft, thirdly, welding all process supports with inner holes of all the baffles in a spot welding way in weight reduction notch space positions arranged on the positioning bases, fourthly, cutting welding lines of the limiting blocks and the bearing seats, laying the limiting blocks in directions perpendicular to disc diameters of the positioning bases, gradually withdrawing the positioning bases and the core shaft, welding a frame body, welding connecting plates among all the baffles, and fifthly, performing thermal aging on the frame body integrally, and then removing all the process supports. The method improves the frame body combination accuracy and the operating efficiency.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment manufacturing, and relates to a method for manufacturing a multi-partition large-aperture box frame. Background technique [0002] The plunger pump is one of the main equipments in petroleum drilling machinery, and the production quality of the plunger pump frame directly affects the quality of the entire plunger pump. The plunger pump frame is a welded box frame with multiple partitions and large apertures (see figure 1 ), there are oil grooves and oil holes on each partition hole, there are currently two methods to produce the plunger pump frame: 1) each partition hole and oil groove are guaranteed by integral processing (see figure 1 ), the inner hole is roughly machined in a single piece of the separator, and the overall finishing hole and oil groove and oil hole are finished after assembly and welding. However, the overall processing of oil grooves and oil holes in some structur...
