Description
Technical field
This utility model relates to technology of die manufacturing field, is specifically related to a kind of off-centre operation core anti-deformation eccentric bushing and controls
Tool.
Background technology
In mould, core forms through hole or the dieparts of blind hole when being to make formed product, is generally divided into injection mold core
With the die casting type heart two class；Because core is the dieparts of product molding, so required precision is high.Along with injection industry and aluminum pressure
Developing rapidly of casting industry, the application of all kinds of section bars is more extensive, and shape is the most various, complicated, mould used
Design and difficulty of processing strengthen the most therewith.And in core, the processing of off-centre operation core has certain difficulty, high-precision partially
The heart round core processing method typically uses eccentric bushing tool combining with digital control lathe or special purpose grinder processing.
Traditional eccentric bushing is to withstand product external diameter with jackscrew with the assembling location mode (see figure 1) of core, passes through jackscrew
The frictional force produced with core extruding eccentric bushing sidewall axially positions and eccentric direction location, produces bigger in position fixing process
Radial force, make eccentric bushing deform, cause eccentric bushing circularity over tolerance, eccentric throw is overproof, finally affects the precision of core.Pass
The eccentric bushing of system is wasted time and energy because of assembling, and working (machining) efficiency is relatively low.Traditional eccentric bushing, because of yielding, is difficult to reuse, substantially
Upper and core one_to_one corresponding assembles, and eccentric bushing quantity is identical with core quantity, causes cost to increase.
Utility model content
For solving problem above, this utility model provides a kind of off-centre operation core anti-deformation eccentric bushing tool.
This utility model the technical scheme is that off-centre operation core anti-deformation eccentric bushing is controlled
Tool, it is characterised in that: including the location division being positioned on core locating surface, location division includes that top wire hole, pin-and-hole, core assist V-type
Groove, alignment pin, jackscrew, alignment pin inserts in pin-and-hole, and alignment pin is stuck in core auxiliary V-groove, and jackscrew inserts in top wire hole, uses
In fixed locating stud.
Described eccentric bushing tool also includes the extended type eccentric bushing for fastening long core and auxiliary sleeve, extended type eccentric bushing
Being placed on the outside of long core, auxiliary sleeve is placed on the end of long core, and the front end of auxiliary sleeve is positioned at extended type eccentric bushing
Portion, between extended type eccentric bushing and auxiliary sleeve, the location division by being positioned on extended type eccentric bushing is fastenedly connected.
A diameter of 2.5 5.0mm of the pin-and-hole of described location division.
The degree of depth of the core auxiliary V-groove of described location division is 0.5 1.0mm.
This utility model uses finger setting to position and fasten, and the position point at eccentric core increases auxiliary V simultaneously
Type groove, after core assembles with eccentric bushing, alignment pin is stuck on V-groove through pin-and-hole, positions and fastens；Long core
Can increase auxiliary sleeve and extend eccentric bushing, will not deform after assembling, assembling is simple, and work efficiency is high, reusable, cost
Low, steady quality.
