Abstract
The utility model discloses a composite cutter holder for boring, which comprises a locking seat, a boring cutter blade seat, a chamfering cutter blade seat, a boring cutter blade supporting seat, a chamfering cutter blade supporting groove, a radial fine-adjusting screw hole, an axial fine-adjusting screw hole and a locking hole. The boring cutter blade seat is provided with the boring cutter blade supporting groove used for clamping a boring cutter blade, and the chamfering cutter blade seat is provided with the chamfering cutter blade supporting groove used for clamping a chamfering cutter blade. The composite cutter holder has the advantages of reasonable force bearing in the cutter blade, high rigidity, smooth chip removal, low cost, high quality, simple structure and convenient operating as well as using.
Description
Technical field
The utility model is chamfering and the specific complex cutter holder that designs simultaneously when satisfying bore hole.Be specially adapted to processing diesel engine cylinder block thrust surface and thrust surface chamfering.
Background technology
In the cylinder of diesel engine process, process the thrust surface chamfering when needing the processing thrust surface, the cutter holder that uses former external introduction is owing to the project organization reason often occurs causing blade vibration, heating, deformation, sharply wearing and tearing even tipping because of the cutter holder unbalance stress adding man-hour, shortened the service life of blade greatly, and the thrust surface chamfering that processes easily produces size phenomenon less than normal.This just needs the frequent detection of workman and toolsetting, a series of additional effort such as tool changing again, has reduced production efficiency, has increased working strength of workers and production cost.
Summary of the invention
The purpose of this utility model is to provide a kind of analysis and calculates blade and adding the stressing conditions in man-hour, by optimal design to holder structure, reasonable Arrangement blade support groove and supporting surface position, improve stressed, the chip removal situation of blade, and then reduce blade and adding the deformation in man-hour, improve the crudy and the stability of part, prolong service life simple in structure of blade and cutter holder, blade is stressed rationally, good rigidly, cost is low, the compound cutter holder of a kind of bore hole that machining accuracy is high.
Technical solution of the present utility model is such, comprise locking bed, boring cutter bar, rose reamer bar, boring cutter sheet supporting seat, chamfering blade support slot, radially finely tune screw, axially finely tune screw, locking hole, the side that it is characterized in that locking bed has boring cutter bar and rose reamer bar, the boring cutter bar has boring cutter sheet support slot, the rose reamer bar has the chamfering blade support slot, and locking bed is fixed tightly on boring machine, the lathe.Locking bed has axial fine setting screw, locking hole, has and radially finely tunes screw.
Boring cutter sheet support slot clamping boring cutter sheet, chamfering blade support slot clamping chamfering blade.
The utility model has the advantages that: blade is stressed rationally, good rigidly, and chip removal is unobstructed, long service life, and workpiece crudy height, independent research production saves production cost.

Among Fig. 1 to Fig. 4, boring cutter sheet support slot (1), chamfering blade support slot (2), radially finely tune screw (3), axially finely tune (6,7) face supporting surface of screw (4), locking hole (5), chamfering blade, (8) face of leaving a blank, processing dimension a to be determined, b value (9,10), chamfer dimesion and determine blade relative position c, d size (11,12), locking bed (13), boring cutter bar (14), rose reamer bar (15).
The specific embodiment
Most preferred embodiment of the present utility model is such, below in conjunction with accompanying drawing, further specifies architectural feature, composition, using method and the operation principle of the utility model bore hole with compound cutter holder.
The utility model bore hole is with the architectural feature of compound cutter holder and consist of: the side of locking bed (13) has boring cutter bar (14) and rose reamer bar (15), boring cutter bar (14) has boring cutter sheet support slot (1) clamping boring cutter sheet, and rose reamer bar (15) has chamfering blade support slot (2) clamping chamfering blade; Locking bed (13) is fixed tightly on the boring machine lathe.Locking bed (13) has axial fine setting screw (4), locking hole (5), has radially to finely tune screw (3).The integral design structure is selected for use 40Cr to carry out the surface and is heat-treated to 45～52HRC, good rigidly; High-accuracy machining center forms processing, guarantees crudy and precision.According to workpiece product drawing chamfer dimesion, analyze the stressing conditions of chamfering blade, holder structure is optimized design and (6,7) face of determining chamfering blade among Fig. 2 is a supporting surface, the free deformation space is reserved to blade in (8) face Free Transform space of leaving a blank.
Through scene processing contrast, significantly reduce or avoided using the problem that is occurred of the cutter holder of former external introduction after adopting the utility model bore hole with compound holder structure.
Specific design of the present utility model and process principle are as follows: in Fig. 3, workpiece size according to required processing requires definite a, b value (9,10) and chamfer dimesion to determine two blade relative position size c, d (11,12), designs 1,2 part-structures among Fig. 1 according to selected blade model again.Remainder is determined according to the boring bar of lathe parameter and installation cutter holder among Fig. 1.
