Description
Technical Field
The utility model belongs to slush pump apparatus for producing relates to the positioner who is applied to slush pump casing riveting operation for oil drilling.
Background
In modern petroleum drilling machine equipment, a mud pump is necessary equipment for a drilling machine, and the mud pump is always responsible for the circulation of drilling fluid in the whole drilling process, is the heart of the drilling machine and is widely applied to the field of land and offshore drilling.
The casing is used as the main support body of the slurry pump and is riveted by plates with different specifications. The positioning reference needs the elastic line to extend to the space, the space positioning size is large, and the error is large. Therefore, the scientific and reasonable riveting method is selected, which is very important for improving the production efficiency of the slurry pump and has important significance for prolonging the service life of the slurry pump. Therefore, the problem of riveting and positioning of the slurry pump is quickly and accurately solved, and the method becomes an urgent task for production and manufacturing units of the slurry pump.
The existing mud pump casing riveting and positioning method comprises the following steps: and (3) performing line snapping lofting on a plane, assembling components such as side plates and the like according to lofting dimensions, assembling the components by using a plane reference of the main components after the main components are assembled, ensuring the space dimension of the components by using an angle ruler, and finally completing the whole riveting.
The existing method has the following problems: firstly, before riveting a slurry pump shell, a sample plate is required to be checked after gas cutting of a left side plate and a right side plate, marking lines are drawn, and ocean punching is performed on the marking lines; second, on a 2000 x 4000 platform, loft and punch a ocean punch: according to a lofting line, the problem exists that plane lofting is too simple, and the line width of the lofting cannot be counted into a measured actual value; and (3) placing a mould only ensuring the flatness of the flange plate on the platform, and fixing the mould on the platform by using a pressing plate. Aligning the machined side (outer side) of the flange plate on the outer side of the clamping fixture, spot-welding the flange plate on the clamping fixture, repeatedly using electric welding positioning for multiple times, and repeating the repairing and polishing procedures. Thirdly, guiding various reference lines on the platform to the edge plate surface by using a corner ruler, and punching foreign-style punching holes; fourthly, the vertical side plate and the side plate are firstly arranged on the edge plate, and the verticality of the vertical side plate and the side plate to the platform is ensured. Then riveting the bottom plate, and jacking the height of the bottom plate to a proper position at the front (end) part of the bottom plate by using a top thread seat; fifthly, when the oil pool bottom plate and the lower side plate are riveted, 4 cushion blocks are placed on two sides of the center line of the shell, and then the front partition plate and the front rib plate are riveted; and finally, positioning the space dimension by using the angle, obviously extending the precision error existing in plane lofting to the space dimension to rivet the bearing seat and the lower seat of the crankshaft bearing. Attention is paid to welding three strong tie-bar square tubes to prevent the left bearing block and the right bearing block from being inclined and inconsistent.
