Abstract
The utility model relates to a novel pump body processing aid structure, which can be used for accurately processing a front spigot and a rear spigot during processing of a pump body of semi-open submersible sewage pump, so that higher concentricity can be maintained. The novel pump body processing aid structure comprises a pump body and is characterized in that the lower end face of the pump body is cast with four lugs distributed uniformly along the circumference, the lugs are shaped like a ladder platform and are 15-20mm high, the bottom ends of the lugs are 35mm long, the outer top ends of the lugs are 30mm long, and the lugs are 25mm thick. The utility model has the advantages that the upper end face, the upper spigot and the lower spigot are processing in the same clamping step, and thus the concentricity and perpendicularity are guaranteed.
Description
Technical field
The utility model relates to a kind of processing supplementary structure of the novel pump housing, be used for adding of the semi-open type proof submersible sand discharging pump pump housing can accurately process man-hour before and after seam, and make it keep higher concentricity.
Background technique
The last seam of the pump housing of semi-open type proof submersible sand discharging pump will reach higher concentricity requirement with following seam, and wants vertical with the upper-end surface of the pump housing.Want the requirement that reaches such, best bet makes seam exactly, manufacturing procedure is finished with in a clamping in seam and upper-end surface down, avoids because the secondary clamping brings error.But now the pump housing of semi-open type proof submersible sand discharging pump the processing after the founding be carry out separately on seam, the clamping of seam and upper-end surface and processing down, therefore certainly existing the clamping error, therefore how can keep it finishing the assurance that manufacturing procedure is a quality of product with in a clamping.
Summary of the invention
The purpose of this utility model be solve institute's semi-open type proof submersible sand discharging pump in the prior art the pump housing in processing seam, need carry out the existing the problems referred to above of secondary clamping when seam and upper-end surface down, a kind of processing supplementary structure of the novel pump housing is provided, and a kind of novel technological method for processing is provided thereupon.The utility model designs a kind of processing supplementary structure of the novel pump housing, comprises the pump housing, it is characterized in that: cast out four along the equally distributed lug of circumference on pump housing lower end surface, lug is a trapezoidal shape, lug height 15～20mm, the long 35mm in bottom, the long 30mm of outer end, lug thickness 25mm.The utility model has the advantages that the upper-end surface, go up seam and following seam is being processed in same clamping, thereby guaranteed concentricity and perpendicularity requirement.
Description of drawings
Below in conjunction with accompanying drawing and example the utility model is elaborated.
Accompanying drawing 1 is a structural representation of the present utility model, and Fig. 2 is the half-sectional view of Fig. 1.
1 is the pump housing, and 2 is last seam, and 3 are following seam, and 4 is the upper-end surface, and 5 is the lower end surface, and 6 is lug, and 7 is flange, and 8 is through hole.
Embodiment
Among the figure: comprise the pump housing, it is characterized in that: cast out four along the equally distributed lug of circumference on pump housing lower end surface, lug is a trapezoidal shape, lug height 15～20mm, the long 35mm in bottom, the long 30mm of outer end, lug thickness 25mm.Course of working is as follows: at first clamp four lugs with four jaw chuck, adopt the method for coreection of " one side one circle " to proofread and correct upper-end surface and last seam respectively, can guarantee that like this upper-end surface and last seam are vertical basically before processing; Clamp four jaw chuck then, the dimensioned with upper-end surface, last seam and following seam puts in place respectively, and satisfies the roughness requirement, and upper-end surface, last seam and following seam are being processed with in a clamping like this, thereby have guaranteed concentricity and perpendicularity requirement; Clamp then and go up seam, the processing lower end surface; The flange of the processing pump housing on boring machine is last at the through hole that gets out on the drilling machine on the flange then.So just finished whole course of working.
