Abstract
The utility model relates to the technical field of mechanical processing tools, in particular to a processing tool for a slender shaft sleeve for an axially split pump. The processing tool is characterized by comprising a boring cutter rod and a lathe dog component, wherein the boring cutter rod is a slender shaft rod; tip locating holes are formed axially in the centers of the two ends of the boring cutter rod respectively, so that ejection and locating of tips are facilitated; more than one floating cutter head mounting hole is formed radially in the boring cutter rod, so that mounting of floating cutter heads in different diameters is facilitated; the floating cutter heads are arranged in the mounting holes; the lathe dog component is arranged at one end of the boring cutter rod, and comprises a locating hoop, a set bolt and a torque rod; the boring cutter rod is sleeved with the locating hoop; the locating hoop is provided with a locating screw hole radially; the upper end of the set bolt is fixed with the torque rod in a crossed manner; and the lower end of the set bolt penetrates through the locating screw hole in the set bolt and pushes against the boring cutter rod to ensure that the boring cutter rod is fixed with the locating hoop, so that torque transmission of the lathe dog component is facilitated. Due to the adoption of the structure, the processing tool has the advantages of being novel in structure, ensuring that inner holes can be processed at the two ends of the shaft sleeve at one time by once clamping, and ensuring the coaxiality of the inner holes and the surface roughness.
Description
Technical field
The utility model relates to machining frock technical field, and specifically a kind of middle-opening pump is with elongated class axle sleeve processing tool.
Background technology
Existing middle-opening pump series pump axle sleeve is typically designed to the axle sleeve of two combinations, and the axle that configures divides rotating, and according to the market user feedback, the situation that adopts the rotating beam warp often to have to order wrong goods occurs, and brings certain difficulty for production management.Company requires to carry out coaxial design for this reason, the pump shaft cover need unite two into one simultaneously, comparing of newly-designed sleeve length and internal diameter is larger, reaches 9 ~ 10:1(and sees accompanying drawing 1), the conventional machining process method of this elongated class axle sleeve is: carry out roughing at lathe first; Then with scroll chuck clamping cylindrical, fine finishining endoporus; Go up at last each spot size of mandrel fine finishining cylindrical.When the fine finishining endoporus, following shortcoming is arranged: the one, piece-holder is oversize, and workpiece can produce shake during rotation; The 2nd,, for guaranteeing that axiality must guarantee that the clamped one time time processing goes out the endoporus at axle sleeve two ends, required like this boring cutter bar is just long, and long boring cutter bar can directly affect its rigidity.2 points to sum up, the endoporus circularity after the fine finishining is inadequate, and axiality is overproof, and bore area has obvious knife mark, and surface roughness does not reach requirement.
Summary of the invention
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, a kind of novel structure is provided, guarantees that clamped one time once can process the endoporus at axle sleeve two ends, and the middle-opening pump that guarantees endoporus axiality and surface roughness is with elongated class axle sleeve processing tool.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of middle-opening pump is with elongated class axle sleeve processing tool, it is characterized in that being provided with boring cutter bar and heart carrier for bolt assembly, boring cutter bar is elongated axostylus axostyle, boring cutter bar two ends central shaft is to being respectively equipped with top locating hole, be beneficial to the top location that holds out against, boring cutter bar radially is provided with more than one floating cutter installing hole, be beneficial to install the floating cutter of different-diameter, be provided with floating cutter in the installing hole, boring cutter bar one end is provided with the heart carrier for bolt assembly, the heart carrier for bolt assembly is by spacer ferrule, tight fixed bolt and torque tube form, and spacer ferrule is enclosed within on the boring cutter bar, and spacer ferrule radially is provided with the positioning filament hole, the tight fixed bolt upper end intersects fixing with torque tube, positioning filament hole and boring cutter bar that the lower end is passed on the tight fixed bolt are inconsistent, and boring cutter bar and spacer ferrule are fixed, and are beneficial to heart carrier for bolt component passes moment of torsion.
The utility model has novel structure, guarantees that clamped one time once can process the endoporus at axle sleeve two ends, and guarantee the advantages such as endoporus axiality and surface roughness owing to adopting said structure.

Fig. 3 is the structural representation of the B-B cutaway view of Fig. 2.
Reference numeral: boring cutter bar 1, heart carrier for bolt assembly 2, top locating hole 3, floating cutter installing hole 4, spacer ferrule 5, tight fixed bolt 6, torque tube 7.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further specified:
As shown in drawings, a kind of middle-opening pump is with elongated class axle sleeve processing tool, it is characterized in that being provided with boring cutter bar 1 and heart carrier for bolt assembly 2, boring cutter bar 1 is elongated axostylus axostyle, boring cutter bar 1 two ends central shaft is to being respectively equipped with top locating hole 3, be beneficial to the top location that holds out against, boring cutter bar 1 radially is provided with more than one floating cutter installing hole 4, be beneficial to install the floating cutter of different-diameter, be provided with floating cutter in the installing hole, boring cutter bar 1 one ends are provided with heart carrier for bolt assembly 2, and heart carrier for bolt assembly 2 is by spacer ferrule 5, tight fixed bolt 6 and torque tube 7 form, spacer ferrule 5 is enclosed within on the boring cutter bar 1, spacer ferrule 5 radially is provided with the positioning filament hole, and tight fixed bolt 6 upper ends intersect with torque tube 7 to be fixed, and positioning filament hole and boring cutter bar 1 that the lower end is passed on the tight fixed bolt 6 are inconsistent, make boring cutter bar 1 fixing with spacer ferrule 5, be beneficial to heart carrier for bolt assembly 2 transmitting torques.
The utility model is when the elongated inner hole of shaft sleeve of fine finishining, size according to inner hole of workpiece, select suitable floating cutter to be installed in the floating cutter installing hole 4, elongated axle sleeve is enclosed within on the boring cutter bar 1, with the top locating hole 3 at boring cutter bar 1 two ends through the top location that holds out against, below, elongated axle sleeve two ends is fixedly connected with slip crate through support column, adjust the support column of slip crate upper end, axle sleeve below, after axially reaching concentric shafts, slender axles covers axle center and boring cutter bar 1 compress, make elongated axle sleeve uniform stressed, guarantee the part accurate positioning, and be difficult for producing distortion, by heart carrier for bolt assembly 2 moment of torsion is passed to boring cutter bar 1, mobile slip crate makes slip crate drive elongated axle sleeve and moves axially along boring cutter bar 1 and carry out finishing of internal diameter.
The utility model has novel structure, guarantees that clamped one time once can process the endoporus at axle sleeve two ends, and guarantee the advantages such as endoporus axiality and surface roughness owing to adopting said structure.
