Abstract

The invention relates to a cam slot ring of arm oscillating motion of wire and cable which needs to solve the problem of matching the cam slot ring with the and oscillating motion of the high-speed braiding machinery. The technology includes the slot ring with inner conical surface. Its characteristics is that the under groove of the inner conical surface is formed as follows: the slot ring rotating along axes of itself, the centre lines of milling cutter and slipping piece are superposition, make the oscillating instantaneous center of the oscillating arm as conic top, the vertical line from conic top to the generatrix of the conical surface inside the slot ring is the rotating centre line, using the half-angle radial of the conic top as the generatrix, and rotating along the oscillating axes of the oscillating arm.

Description

The cam slot ring of electric wire braiding machine swing arm campaign

Technical field:

The present invention relates to the groove circle of electric wire braiding machine guiding swing arm campaign.

Background technology

During the work of electric wire braiding machine, periodically swing up and down braided wires guiding braiding point by swing arm, the braiding machine swing arm is to make braided wires form netted main moving parts.The braiding machine swing arm has slide block, and slide block is stretched in the waveform groove of groove circle inner conical surface.Cam slot ring is the vital part of electric wire high-speed knitter, and when groove circle and swing arm relatively rotated, the slide block of swing arm moved along the waveform groove of groove circle, realizes that swing arm does the swing of certain amplitude of oscillation by curvilinear path, around the rotating shaft of one end.Therefore, form the three-dimensional curve of waveform groove and groove two sides with respect to the position of groove circle inner conical surface whether with the movement locus coupling of swing arm, be a key factor that influences the complete machine performance.The track of groove circle waveform groove just is similar to the movement locus of slide block at present, the two sides of waveform groove are perpendicular to the inner conical surface bus, inconsistent with the movement locus of slide block, its shortcoming is a slide block when motion and the two sides of groove produce interference, cause that complete machine running vibration is big, noise greater than 82 decibels, parts depreciation aggravation, wire broken rate height, can't be used for metal wire knitted, machine master turning spur speed below the Φ 0.05mm less than 205 meters/minute, can't further improve.Along with developing rapidly of electronic technology, communication industry, wires and cables industry is to the shielding and the anti-interference demands for higher performance of cable, application constantly enlarges, use amount is more and more, and the performance of improving high-speed knitter becomes urgent problem with the metal wire knitted that adapts to below the Φ 0.05mm.

Summary of the invention

At present groove circle waveform groove is to do gyration by the groove circle around self axis, perpendicular to the milling cutter of groove circle inner conical surface bus numerical control program control lower edge inner conical surface generatrix direction up and down translation form, produce corrugated groove and the inconsistent problem of slide block movement track, the object of the present invention is to provide cam slot ring a kind of and high-speed knitter swing arm movement locus coupling.

Technical scheme of the present invention includes the groove circle of inner conical surface, it is characterized in that groove circle inner conical surface to be shaped on the instantaneous centre of swinging around the revolution of self axis, milling cutter center line and slide block central lines, with swing arm at the groove circle be the vertex of a cone, the vertex of a cone to the vertical line of groove circle inner conical surface bus be the axis of oscillation of swing arm be rotation centerline, with vertex of a cone half-angle ray be bus, the waveform groove that under swing arm axis of oscillation rotating conditions, forms.

The present invention is because the waveform groove is the formation of mock pendulum arm swing state, its center of surface is consistent with the instantaneous centre of swing arm swing, changed the defective of original waveform groove two sides with the vertical existence of inner conical surface bus, the movement locus coupling of waveform groove and swing arm, can not produce interference during slide block movement, the complete machine running steadily, noise is little, part is not easy to wear, wire broken rate significantly reduces, can be used for the following metal wire knitted of Φ 0.05mm, solved the difficult problem that existing braiding machine can't be used for the following metal wire knitted of Φ 0.05mm, also made machine master turning spur speed be able to further raising.

Description of drawings

What accompanying drawing was represented is that the geometry that cam slot ring of the present invention and waveform groove thereof are set will be put schematic diagram.

Embodiment

Implement best way of the present invention below in conjunction with description of drawings:

Technical scheme of the present invention comprises the groove circle of being with inner conical surface, accompanying drawing represents that the waveform groove 31 of groove circle inner conical surface is to do gyration at the groove circle around self axis 35, milling cutter center line 32 and slide block 21 central lines, milling cutter is under the control of numerical control program, the analog slider motion, instantaneous centre A point with the swing arm swing is that the vertex of a cone, A point to the vertical line 33 of inner conical surface 34 buses are that the swing arm axis of oscillation is a rotation centerline, vertex of a cone half-angle alpha ray is that milling cutter center line 32 is bus, form around swing arm axis of oscillation 33 rotation, the amplitude of milling cutter swing is the distance between last low groove.Above-mentioned waveform groove 31 forms by the analog slider motion state, therefore, its central surface is through the A point, waveform groove 31 two sides 36 are consistent with the movement locus of swing arm slide block with respect to the position of groove circle inner conical surface 34, slide block can not produce interference when motion, be applicable to the cam slot ring of electric wire high-speed knitter series all size.
