Abstract
The invention relates to the technical field of a tool for mechanical processing, in particular to a tool for processing a long and thin shaft sleeve for an axially split pump, which is characterized by comprising a boring cutter rod and a lathe carrier assembly, wherein the boring cuter rod is of a long and thin shaft rod, the central shafts of the two ends of the boring cutter rod are respectively provided with a tip positioning hole for jacking and positioning a tip, the boring cutter rod is radially provided with more than one floating cutter heat installing hole for installing floating cutter heads with different diameters, the floating cutter heads are arranged in the installing holes, one end of the boring cutter rod is provided with the lathe carrier assembly, the lathe carrier assembly comprises a positioning hoop, a fastening bolt and a torque rod, the positioning hoop is sleeved on the boring cutter rod and is radially provided with a positioning screw hole, the upper end of the fastening bolt is fixed with the torque rod in a crossed way, the lower end of the fastening bolt passes through the positioning screw hole in the fastening bolt to be contacted with the boring cutter rod, so that the boring cutter rod is fixed with the positioning hoop, and further, the lathe carrier assembly can transmit torque. Due to the adoption of the structure, the tool has the advantages that the structure is novel, inner holes at the two ends of the shaft sleeve can be processed at one-time clamping, the coaxiality and surface roughness of the inner holes can be ensured, etc.
Description
Technical field
The present invention relates to machining frock technical field, specifically a kind of middle-opening pump is with elongated type of axle sleeve processing tool.
Background technology
Existing middle-opening pump series pump is used axle sleeve, is typically designed to the axle sleeve of two combinations, and the axle that is disposed divides rotating, and according to the market user feedback, the situation that adopts the rotating beam warp often to have to order wrong goods takes place, and brings certain degree of 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 bigger, reaches 9 ~ 10:1 (seeing accompanying drawing 1), and the conventional machining process method of this elongated type of axle sleeve is: on lathe, carry out earlier roughing; 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,, must guarantee that for guaranteeing axiality clamping 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 influence its rigidity.2 points to sum up, the endoporus circularity after the fine finishining is not enough, and axiality is overproof, and bore area has tangible knife mark, and surface roughness does not reach requirement.
Summary of the invention
The objective of the invention is to solve the deficiency of above-mentioned prior art, the endoporus that provides a kind of novel structure, clamping of assurance once can process the axle sleeve two ends, and the middle-opening pump of assurance endoporus axiality and surface roughness is with elongated type of axle sleeve processing tool.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of middle-opening pump is characterized in that being provided with boring cutter bar and heart clip assembly with elongated type of axle sleeve processing tool, and boring cutter bar is elongated axostylus axostyle; Boring cutter bar two ends central shaft is beneficial to the top location that holds out against to being respectively equipped with top locating hole, and boring cutter bar radially is provided with more than one unsteady cutter head installing hole; Be beneficial to install the unsteady cutter head of different-diameter, be provided with unsteady cutter head in the installing hole, boring cutter bar one end is provided with the heart clip assembly; The heart clip assembly is made up of spacer ferrule, tight fixed bolt and torque tube, and spacer ferrule is enclosed within on the boring cutter bar, and spacer ferrule radially is provided with silk hole, location; Tight fixed bolt upper end and torque tube cross fixation; Silk hole, location 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 the heart clip assembly and transmit moment of torsion.
The present invention has novel structure, guarantees that a clamping once can process the endoporus at axle sleeve two ends, and guarantee advantages such as endoporus axiality and surface roughness owing to adopt said structure.

Reference numeral: boring cutter bar 1, heart clip assembly 2, top locating hole 3, unsteady cutter head installing hole 4, spacer ferrule 5, tight fixed bolt 6, torque tube 7.
The specific embodiment:
Below in conjunction with accompanying drawing the present invention is further specified:
Shown in accompanying drawing, a kind of middle-opening pump is characterized in that being provided with boring cutter bar 1 and heart clip assembly 2 with elongated type of axle sleeve processing tool; Boring cutter bar 1 is elongated axostylus axostyle, and boring cutter bar 1 two ends central shaft is beneficial to the top location that holds out against to being respectively equipped with top locating hole 3; Boring cutter bar 1 radially is provided with more than one unsteady cutter head installing hole 4, is beneficial to install the unsteady cutter head of different-diameter, is provided with unsteady cutter head in the installing hole; Boring cutter bar 1 one ends are provided with heart clip assembly 2, and heart clip assembly 2 is made up of spacer ferrule 5, tight fixed bolt 6 and torque tube 7, and spacer ferrule 5 is enclosed within on the boring cutter bar 1; Spacer ferrule 5 radially is provided with silk hole, location, tight fixed bolt 6 upper ends and torque tube 7 cross fixation, and silk hole, location 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, be beneficial to heart clip assembly 2 and transmit moment of torsion with spacer ferrule 5.
The present invention according to the size of workpiece endoporus, selects suitable unsteady cutter head to be installed in to float in the cutter head installing hole 4 when the elongated axle sleeve endoporus of fine finishining; The slender axles cover is enclosed within on the boring cutter bar 1, and through the top location that holds out against, below, elongated axle sleeve two ends is fixedly connected with slip crate through support column with the top locating hole 3 at boring cutter bar 1 two ends; The support column of slip crate upper end, adjustment axle sleeve below; Compress after axially reaching concentric shafts when slender axles covers axle center with boring cutter bar 1, make elongated axle sleeve evenly stressed, the accurate positioning of assurance part; And be difficult for producing distortion; Through heart clip assembly 2 moment of torsion is passed to boring cutter bar 1, move slip crate, make slip crate drive elongated axle sleeve and move axially along boring cutter bar 1 and carry out endoporus fine finishining.
The present invention has novel structure, guarantees that a clamping once can process the endoporus at axle sleeve two ends, and guarantee advantages such as endoporus axiality and surface roughness owing to adopt said structure.
