Description
Technical field
The present invention relates to optical instrument field, particularly relate to a kind of concentricity auxiliary governor.
Background technology
In mechanical processing industry, concentricity be had higher requirements by a lot of local meetings.As a example by wires and cables industry, insulation and the extrusion of sheath have higher requirement to concentricity, if concentricity is relatively low and cause core shift, it will affect use safety and the service life of product.Therefore, bed die and core rod, when extrusion between the bed die and core rod of mould, will be regulated by overwhelming majority product with one heart, make bed die and core rod concentricity height as far as possible, and the product core shift situation of extrusion just can be more preferably.
At present, the adjustment of mould concentricity is all hand-held bed die, then bed die is translated, process in translation constantly extrudes Insulation Material or protective cover material, the most visually the wall thickness of Insulation Material or protective cover material the most uniformly judges whether with one heart, during this, need repeatedly to regulate to can be only achieved promising result, the process adjusted is the veryest long, need to extrude a lot of Insulation Material or protective cover material could finally judge its uniform wall thickness, therefore often material and semi-finished product be will result in during adjusting waste, time and effort consuming greatly；Further, owing to lacking the benchmark of reference during regulation, being only capable of being carried out the regulation of concentricity by range estimation and experience, therefore concentricity is the highest.
Summary of the invention
The invention is intended to provide a kind of concentricity auxiliary governor, to regulate the concentricity of cable extrusion mould efficiently and accurately.
Concentricity auxiliary governor in this programme, including pedestal, pedestal is cylindric, is provided with transparent scale plate in pedestal, and scale plate is circular, and scale plate is provided with concentric scale line, and scale plate is concentric with concentric scale line；Having the chute parallel with base axis on described pedestal, slidably connect scale plate folder in chute, scale plate folder can slide along the direction being parallel to base axis, and scale plate is arranged on scale plate folder.
The know-why of this programme and have the beneficial effect that bed die one end that base bottom is against mould, translation base bottom, slip scale plate folder simultaneously, make scale plate translate along the axis direction of pedestal in pedestal, slide, observe the concentric scale line on scale plate, make the circular hole on core rod (this hole regards as fixing circle) overlap with a certain concentric scale line on scale plate；After coincidence, keeping pedestal and scale plate folder static, translate bed die, make the circular hole on bed die (this hole regards as movable circle) overlap with another concentric scale line on scale plate, now core rod i.e. reaches concentric with bed die.
This programme, using concentric scale line as the basis of reference of regulation with one heart, has only to during regulation ensure that the circular hole being conditioned overlaps with the concentric scale line on scale plate, can ensure concentricity, and the concentricity of the mould after adjustment is high.Meanwhile, need not during adjustment extrude raw material, thus without consumption of raw material, waste will not be produced, and simple in construction, easy to use, improve the efficiency of concentricity regulation.
Scheme based on such scheme, prioritization scheme one based on base case: also including upper cover, detachable upper cover unloads and is connected to Chuck top, above covers and is provided with convex lens.One end relative with bottom on pedestal is top, in use, sight line typically requires the top through pedestal and observes whether concentric scale line aligns with circular hole, at Chuck top, convex lens is installed, convex lens has amplification, can more clearly be observed the alignment condition of concentric scale line by convex lens.On the other hand, when the concentric scale line without suitable size can align with fixing circle, slidably scale plate, the now imaging of the concentric scale line in convex lens will occur size, the change of density, observe the interior change of concentric scale line in convex lens, it it is now the basis of reference regulated with one heart with the concentric scale line after change in convex lens, sight line is moved to directly over convex lens, concentric scale line after changing in observing convex lens, when observing that fixing circle aligns with the concentric scale line after a certain change, stop slip scale plate, and keep scale plate static, translation bed die, the movable circle on bed die is made to align with the concentric scale line after another change in convex lens, also bed die and core rod after can making regulation have the highest concentricity.Therefore, the setting of convex lens not only can allow an operator to the apparent alignment condition observing concentric scale line and circular hole, moreover it is possible to increases the scope of application of this actuator, to be applicable to concentricity in more broad range, mould that have different size Circular Aperture regulation.Upper cover removably connects with Chuck top, it is simple to dismounting upper cover.
Prioritization scheme two based on prioritization scheme one: described scale plate is aspherical mirror.Aspheric surface is the curvature generation continually varying lens being easy to from lens centre to lens, and aspherical mirror can make the imaging in lens have higher acutance and resolution.When using convex lens observation concentric scale line whether to align with circular hole, need the concentric scale line simultaneously observing on scale plate and be positioned at the circular hole below concentric scale line, owing to convex lens can only focus on a point, the focus of convex lens or focus on concentric scale line, focus on circular hole, such as when focusing on concentric scale line, the imaging of the circular hole seen is fuzzyyer relative to concentric scale line.When scale plate is aspherical mirror, relative to conventional plane mirror, circular hole can be allowed to form acutance and the higher imaging of resolution on scale plate, when observing the imaging on scale plate of concentric scale line and circular hole by convex lens the most again, can more clearly see whether concentric scale line aligns with circular hole imaging on scale plate clearly, and then be more beneficial for judging whether concentric scale line aligns with circular hole.Further, convex lens is usually coquille, and coquille easily produces spherical aberration, causes light can not converge to focus, thus causes image blur, is unfavorable for whether accurate observation concentric scale line aligns with circular hole.When scale plate is aspherical mirror, can be conducive to light collection to focus, and then effectively eliminate the spherical aberration that convex lens produces, and then be more beneficial for whether accurate observation concentric scale line aligns with circular hole.
Based on prioritization scheme one or the prioritization scheme three of arbitrary one of prioritization scheme two: described in be detachably connected as screw connect.Being fixed on pedestal by upper cover by screw, prevent upper cover from coming off and break the convex lens that covers installation, screw connects the dismounting also allowing for upper cover simultaneously.
Prioritization scheme four based on prioritization scheme three: described pedestal side has endless groove.Person convenient to operate grabs and takes and anti-skidding.
Prioritization scheme five based on prioritization scheme four: if described base bottom has dry hole, be provided with Magnetitum in hole.It is easy to pedestal is passed through the magnetic-adsorption of Magnetitum on mould.
Prioritization scheme six based on prioritization scheme five: described Chuck top is provided with the boss that several are inside, boss is provided with illuminating lamp, and described pedestal top also has groove, is provided with button cell and electric wire in groove, and electric wire connects button cell and illuminating lamp.Owing to pedestal is cylindric, therefore base interior normal daylight is dark, and illuminating lamp can illuminate base interior when concentricity adjusting.
Prioritization scheme seven based on prioritization scheme three: being fixed with threaded rod on described scale plate folder, threaded rod is slidably connected in the chute on pedestal, and screw thread is provided with the nut matched.Nut is typically mounted on threaded rod, by screwing nut, in chute scale plate folder can being fixed on pedestal.
