Abstract

The utility model adopts a revolving electric winding unwinder which is composed of a winding unwinder bed body 15, a motor 2, a reduction box 3, a steel cable rolling drum 4, a steel cable 5, a hanging hook 6, a pair of wire clipping pliers 7, a double-head bolt 8, nuts 9, a press board 10, a T-shaped base 12 and a revolving table 13. The revolving electric winding unwinder is used for dismantling the coils of the medium and the miniature AC motor stators without damaging the iron core slot of the motor stator. The insulated paint between the silicon iron sheets of the stator core can not be damaged by aging, which ensures the quality after the motor is repaired. When the utility model is used, the electric winding unwinder saves time and labor, improves the working condition and reduces the hand work and the environment pollution.

Description

The electronic line machine that pulls out

Technical field

The utility model relates to a kind of electronic line machine that pulls out, and is used to repair medium and small alternating current machine stator coil.

Background technology

The stator coil of medium and small alternating current motor is circle enamel covered wire coiling, soaks that insulating varnish after heat baking solidifies, and is difficult to remove.The method that tradition is used has: the manual method of taking out stitches, engraving tool are towards method, the pneumatic collimation method that pulls out.By hand the method for taking out stitches be motor in 200 ℃ of bakings of high temperature, make the insulating varnish ageing failure after, craft is taken out stitches; Engraving tool is carved the end of stator coil disconnected along the stator coring groove place towards method, with steel bar the straight portion of the coil in stator core integral body is gone out again; The pneumatic collimation method that pulls out is that motor stator is heated to 200 ℃, extracts coil with pneumatic tool.More than three kinds of methods time-consuming, efficient is low, the dust chip is many, handwork labour intensity is big, and damages the electric machine stator iron groove easily, and high temperature has destroyed the lamination insulation between the silicon iron sheet unshakable in one's determination again, the motor stator-core loss is increased, and the motor quality after the repairing is difficult to guarantee.

The utility model content

The purpose of this utility model is in order to overcome the defective that said method exists, to provide a kind of simple in structure, be convenient to operation, can guaranteeing the electronic line machine that pulls out of motor stator repairing quality again.

In order to achieve the above object, the utility model adopt a kind of can the rotating electronic line machine that pulls out, it is formed by pulling out line bed piece 15, motor 2, reduction box 3, wire rope drum 4, steel wire rope 5, suspension hook 6, clamp pincers 7, stud 8, nut 9, pressing plate 10, T type base 12, rotary table 13.Pull out line bed piece top motor is housed, motor links to each other with reduction box by power transmission shaft, reduction box links to each other with wire rope drum by another power transmission shaft, cylinder below is by the steel wire rope suspension hook that vertically plays, hang mobilizable clamp pincers on the suspension hook, rotary table is provided with a T type base, and bolt of stud can be fixed on motor stator on the rotary table by stud, pressing plate, nut on T type base.

Pull out the line bed piece and be provided with an electromagnetic brake and link to each other with motor, when crawl stopped, electromagnetic brake was with motor braking, and suspension hook and the ascending motion of clamp pincers stop immediately, prevent to pull out the inertia in the line process, guarantee operating personnel's safety.

With removing medium and small alternating current machine stator coil by the rotating electronic line machine that pulls out, do not damage the electric machine stator iron groove, and stator pulls out that the baking stator temperature is no more than 120 ℃ before the line, therefore, insulating varnish between the stator core silicon iron sheet can not wear out and damage, the quality behind the assurance motor repair.Use this utility model to save time, laborsaving, and improved working condition, and reduced handwork, reduced environmental pollution.

Description of drawings

Fig. 1 is for can turn round the electronic line machine overall structure schematic diagram that pulls out.

Pull out line bed piece top among the figure electromagnetic brake 1, motor 2, reduction box 3, wire rope drum 4 are installed, cylinder below is by steel wire rope 5 suspension hook 6 that vertically plays, hang mobilizable clamp pincers 7 on the suspension hook, pull out line bed piece bottom and change workbench 13 once, rotary table is provided with a

T type base

12,8 one bolts of stud are on T type base, motor stator 11 can be fixed on the rotary table by stud 8, nut 9, pressing plate 10, and guarantee the end of suspension hook aligning stator winding coil 16.Pull out the upwards button 14 that is equipped with motor 2 on the line bed piece.

Specific embodiment

Pull out of lead end end vertical lathe or milling machine on the neat iron core notch place cut-out of the preceding elder generation of line, again motor is inserted in the baking oven, heat up 120 ℃, the insulating varnish on the motor coil is softened the alternating current machine stator coil of damage.

While hot motor stator 11 is placed on the electronic rotary table 13 that pulls out the line machine, an end that leaves end winding up, by stud 8, T type base 12, nut 9 is fixed on motor stator on the rotary table, guarantee the certainly sub-winding coil of suspension hook 6 alignings one end, clamp one group of overhang with clamp pincers 7, clamp with wing nut, also but other mode clamps, prevent the coil slippage, again clamp is hung on the suspension hook, press motor button 14 crawls that make progress, suspension hook moves upward, and strap clamp line molybdenum is extracted whole one group of coil in core slots.When crawl stopped, braking electromagnet 1 was with motor braking, and the ascending motion of suspension hook and clamp pincers stops immediately, prevents to pull out the inertia in the line process, guarantees operating personnel's safety.Rotate rotary table 13 and extract each coil successively.Because it is parallel with core slots all the time to pull out the line direction, tiltedly do not draw phenomenon just can not damage core slots when pulling out line.

Because the baking stator temperature is no more than 120 ℃, the insulating varnish between the stator core silicon iron sheet can aged deterioration, guarantees the quality behind the motor repair.
