Abstract
The utility model relates to a delivery gear used for machining two end faces and a positioning stop of a pump body, which comprises a power driven boring bar on a boring power unit. The utility model is characterized in that the boring bar is supported by a boring bush fastened on a center opening surface of the pump body, a delivering gear is arranged on the boring bar, the delivering gear is sheathed on the boring bar by a hough hole fastened by a screw bolt and a screw nut, the lower end of the delivering gear is provided with a drive plate which corresponds to a shift lever fixed on a flat plate. The delivering gear is composed of a cutter frame, a screw rod, the drive plate, a guideway and a sliding seat, wherein the cutter frame is arranged on the sliding seat which is positioned in the guideway, the sliding seat is provided with a screw nut which connects with the screw rod and the other end of the screw rod is fixedly connected with the drive plate. The utility model has the advantages that the delivering gear can accurately machine two end faces and a positioning stop of a pump body, and ensures the verticality of the two end faces.
Description
Technical field
The utility model relates to a kind of delivering gear, particularly a kind of delivering gear that is used to process pump housing biend and positioning spigot.
Background technology
The biend of dress bearing body and the processing of inside and outside circle positioning spigot on the middle-opening pump pump housing at present, be to be placed in the T68 boring for sleeping in, concrete procedure of processing is as follows: pump housing clamping is on workbench, knife rest is contained on the lathe facing head, lathe drives facing head and rotates on one side, drive radially feed of knife rest on one side, process an end face on the pump housing, inside and outside circle positioning spigot, again work table rotation smoothed with special measurement device for 180 °, school manufactured end face of circle and inside and outside circle positioning spigot process other end, inside and outside circle positioning spigot.Because pump housing biend, inside and outside circle positioning spigot divide secondary operations, because of factors such as machine tool error, measure error, correction error, mismachining tolerance make the biend depth of parallelism of processing, inside and outside circle positioning spigot big to the error of perpendicularity of biend, do not reach the drawing requirement, so product assembling back rotor part rotates dumb, with catching phenomenon, the running phenomenon that burns out a bearing constantly causes poor product quality, and new product can't be put on market.
Summary of the invention
The purpose of this utility model is to solve in the prior art biend of dress bearing body on the pump housing and inside and outside circle positioning spigot to be added the existing biend depth of parallelism of work point secondary operations and inside and outside circle positioning spigot biend is had the problem of the big error of perpendicularity, provides a kind of and can finish biend and the inside and outside circle positioning spigot delivering gear little to the biend error of perpendicularity on the pump housing.A kind of delivering gear that is used to process pump housing biend and positioning spigot of the utility model design, comprise that the power on the boring unit head drives boring bar, it is characterized in that: boring bar supports by being fastened on the boring lining of opening in the pump housing on the face, one delivering gear is arranged on the boring bar, the fastening Hough borehole jack of the useful bolt and nut of delivering gear is on boring bar, in the delivering gear lower end one dial is arranged, dial is with respect to a driving lever that is fixed on the flat board.Delivering gear is made of knife rest, screw mandrel, dial, guide rail, sliding seat, and knife rest is installed on the sliding seat, and the sliding seat of gig has nut to connect screw mandrel, the fixedly connected dial of the screw mandrel other end in guide rail on the sliding seat.The utility model has the advantages that and to process pump housing both ends of the surface and inside and outside circle positioning spigot exactly, and guarantee the delivering gear of both ends of the surface perpendicularity.

Below in conjunction with drawings and Examples the utility model is elaborated,
Accompanying drawing 1 is a structural representation of the present utility model,
Accompanying drawing 2 is a delivering gear structure schematic top plan view of the present utility model,
Accompanying drawing 3 is a delivering gear texture edge schematic diagram of the present utility model,
Accompanying drawing 4 be the K of delivering gear Fig. 2 of the present utility model to partial schematic diagram,
The specific embodiment
Comprise the boring bar 1 that the power on the boring unit head drives among the figure, it is characterized in that: boring bar 1 supports by being fastened on the boring lining of opening in the pump housing on the face 2, one delivering gear 3 is arranged on boring bar 1, delivering gear 3 useful bolt and nuts 4 fastening Hough holes 5 are enclosed within on the boring bar 1, in delivering gear 3 lower ends one dial 6 is arranged, dial 6 is with respect to a fixing driving lever 7.Delivering gear 3 is made of knife rest 8, screw mandrel 9, dial 6, guide rail 10, sliding seat 11, and knife rest 8 is installed on the sliding seat 11, and sliding seat 11 is positioned at guide rail 10, has nut 12 to connect screw mandrel 9, the fixedly connected dial 6 of screw mandrel 9 other ends on the sliding seat 11.
The power of boring unit head drives boring bar 1 rotation by universal joint during use, delivering gear 3 is with boring bar 1 rotation, dial 6 revolutions of delivering gear 3 lower ends move once will run into fixed driving lever 7, make dial 6 rotate a five equilibrium, dial 6 drives screw mandrel 9, knife rest 8 advances and finishes a feed.Delivering gear 3 continuous fast rotational, the processing of the pump housing one end face and inside and outside circle positioning spigot is finished in knife rest 8 continuous feeds.
It is fastening the Hough hole 5 of delivering gear 3 to be set on the boring bar 1 of the pump housing other end back, repeats above-mentioned process, and other end, the inside and outside circle positioning spigot of the pump housing machined.
Can process high-precision biend like this, inside and outside circle positioning spigot, key is the Hough hole (φ 80H7) of delivering gear 3 and perpendicularity＜0.02 on two planes of the guide rail 10 of dovetail, could guarantee that knife rest 8 processes perpendicularity＜0.03 of biend and boring bar axial line on the pump housing, rotor part rotates flexibly after making the middle-opening pump general assembly, and the complete machine running steadily.
