Abstract

The utility model relates to a motor coil inserting slot insulation cutting fixture, in particular to a rail-mounted slot insulation paper knife which solves the problem that the prior coil inserting continuous wavy type slot insulation cutting effect is not good. The rail-mounted slot insulation paper knife comprises a rail and a paper knife the edge of which is upward, the paper knife is symmetrically provided with bearings which can roll along the rail through a fixing shaft; the rail comprises a U-shaped guide slot, the two ends of which are respectively provided with a pair of locating pins which is fixedly clamped at the two linear sides of the coil; the inner slot width of the U-shaped guide slot is identical to the width of the bearing on the paper knife, the outside slot width of the U-shaped guide slot is identical to the linear width of the coil, and the distance between the two pair of locating pins is identical to the linear length of the coil. The rail-mounted slot insulation paper knife has simple structure, convenient paper cutting and good commonality, ensures that the linear angle of the slot insulation is symmetrical to insulation materials at two sides in the cutting process, can be popularized to the procedure of continuous wavy type slot insulation cutting of stator coil inserting, thereby having strong popularization.

Description

Rail mounted slot insulation paper knife

Technical field

The utility model relates to motor coil line embedding groove insulation cutter cut dress, specifically is a kind of rail mounted slot insulation paper knife.

Background technology

The slot insulation of motor coil is generally put into core slots with whole Zhang Lianxu wave, and the slot insulation material adopts 0.18Nomex paper; Because slot insulation is continuous, after coil embeds in the core slots, need utilize single face security personnel blade that the slot insulation between two lines is severed, again the insulating paper on notch both sides is broken slot wedge to folding; And when using single face security personnel blade to sever slot insulation, the rule employee is difficult to the direction of control blade, cause to sever line and crawl, and slot insulation both sides width is very asymmetric, and when breaking slot wedge, slot insulation is battered down easily, the wedging of prevention slot wedge; Can reduce the coil insulation grade because the breakage of slot insulation causes the breakage of coil surface insulation against ground, increased unnecessary patch work, and the degree of tightness that the coil in each groove embeds be inconsistent.

Summary of the invention

The utility model provides a kind of rail mounted slot insulation paper knife in order to solve the not good problem of present coil rule continuous wave slot insulation shear effect.

The utility model is to adopt following technical scheme to realize: rail mounted slot insulation paper knife, comprise the paper knife that track and cutting edge make progress, and being symmetrically arranged with by fixed axis on the paper knife can be along the bearing of track rolling; Track comprises the U-shaped gathering sill, the two ends of U-shaped gathering sill are respectively arranged with a pair of alignment pin that is used for fixing in coil straight line (being effective edge) both sides, the groove insied width of U-shaped gathering sill is consistent with the bearing width on the paper knife, the outer width of the groove of U-shaped gathering sill is consistent with the coil linear width, and the distance between the two pairs of alignment pins is consistent with the coil straight length.

During use, at the slot insulation of motor coil with whole Zhang Lianxu wave, after in coil embeds core slots, the alignment pin of U-shaped gathering sill by two ends fixed on the coil straight line, then the monolateral bearing on the paper knife is placed in the U-shaped gathering sill, promote bearing and move, carry out pushing away of U-shaped gathering sill one side earlier and cut, carry out pushing away of another side again and cut along the U-shaped gathering sill; Because slot insulation is subjected to the downward pulling in coil both sides, cause slot insulation to apply on iron core, must suitably adjust the incision angle of paper knife, push away and cut operation so that finish a slot insulation smoothly.

Compared with prior art, adopt paper knife described in the utility model that slot insulation is cut off after, slot insulation both sides size is equal substantially, linearity is straight, no burr; When breaking slot wedge, the slot insulation both sides laminate size and equate that slot wedge contacts closely with slot insulation, and the degree of tightness unanimity that the coil in each core slots is embedded meets technological requirement; Damage in insulation when avoiding breaking slot wedge, and cause the situation of coil ground connection to occur.

The utility model is simple in structure, cuts a sheet of paper conveniently, and versatility is good, has guaranteed the linearity of slot insulation in the process of severing and the symmetry of both sides Insulation Material; Extend in the operation that the continuous wave slot insulation of similar stator built-in line shears, generalization is strong.

The specific embodiment

Rail mounted slot insulation paper knife comprises the paper knife 2 that track and cutting edge 1 make progress, and being symmetrically arranged with by fixed axis 3 on the paper knife 2 can be along the bearing 4,5 of track rolling; Track comprises U-shaped gathering sill 6, the two ends of U-shaped gathering sill 6 are respectively arranged with a pair of alignment pin 7 that is used for fixing in coil straight line (being effective edge) both sides, the groove insied width of U-shaped gathering sill 6 is consistent with the bearing width on the paper knife 2, the outer width of the groove of U-shaped gathering sill 6 is consistent with the coil linear width, and the distance between the two pairs of alignment pins 7 is consistent with the coil straight length.

Claims
