Abstract
The invention discloses a shearing tool for the insulation paper of a rotor slot of a miniature motor. The shearing tool comprises a tool holder and a tool bit. The tool bit has a zigzag structure with three teeth which comprises a middle entire tooth with cutting edges and two half teeth on the two sides of the entire tooth, wherein the two half teeth are symmetrical about the middle entire tooth; the inner sides of the two half teeth are provided with a cutting edge respectively; and the width of the tooth root of the entire tooth is equal to the length of a sandwiched arc of an outer circle between two adjacent slots of a rotor. When the shearing tool for the insulation paper of the rotor slot of the miniature motor is used, the two half teeth of the tool are arranged between the insulation paper and the outer circle of a rotor core respectively, the middle entire tooth is arranged on the outer circle of the rotor core, the tool holder applies a thrust to the tool, and the tool bit moves forwards along the outer circle of the rotor core to cut off the insulation paper at the two ends of the rotor slot at the same time. Compared with the prior art, the shearing tool shortens process time for removing the insulation paper of the rotor slot of the miniature motor to be 1/3 of original process time, improves labor productivity and decreases the production cost of an enterprise.
Description
Technical field
The present invention relates to a kind of micromotor supplement production equipment, relate in particular to a kind of shearing tool that is used to remove the insulating paper of micromotor rotor.
Background technology
At present, after the micromotor rotor winding finished, the insulating paper that must will cover the rotor core outer surface was removed; The removing method of prior art is with scissors insulating paper to be cut off from the centre, respectively insulation paper cutting is removed along groove Zuo Bi, right wall, according to said method again; Remove a slot liner paper; The necessary repetitive operation of workman 3 times, therefore traditional removing method exists labour intensity big, the shortcoming that efficiency is low and production cost is higher.
Summary of the invention
The object of the present invention is to provide a kind of micromotor rotor slot insulation paper shearing tool; It has simple in structure, be easy to realize, cost is lower, simple operation and the high characteristics of production efficiency; The labour intensity that has effectively solved the insulating paper existence of removing the micromotor rotor in the prior art is big, the problem that efficiency is low.
The objective of the invention is to realize through following technical scheme:
A kind of micromotor rotor slot insulation paper shearing tool, it comprises handle of a knife and cutter head, wherein; Said cutter head is a zigzag structure, has three teeth altogether, and the centre is the whole tooth of tool cutting edge; The both sides of said whole tooth are half tooth; Said two and half teeth are whole tooth symmetry along the centre, and the inboard of said two and half teeth all has cutting edge, and the tooth root of said whole tooth is wide, and to equal the grip hold arc of cylindrical between adjacent two grooves of rotor long.
Especially, said handle of a knife is the rectangle flat structure.
Especially, the crown of said whole tooth and half tooth is 0.8～1.5cm to the length of tooth root.
Beneficial effect of the present invention does; Said micromotor rotor slot insulation paper shearing tool is put into two and half teeth of cutter respectively between the cylindrical of insulating paper and rotor core in use; Middle whole tooth is placed on the cylindrical of rotor core; To the cutter applied thrust, cutter head moves ahead along the periphery of rotor core through handle of a knife, and the insulating paper with the rotor right ends cuts off simultaneously.It is original 1/3 that the activity time that micromotor slot liner paper is removed shortens to, and improved labor productivity, reduced the production cost of enterprise.
Description of drawings
According to accompanying drawing and embodiment the present invention is done further explain below.
Fig. 1 is the end view of micromotor rotor slot insulation paper shearing tool of the present invention.
Among the figure:
1, handle of a knife; 2, whole tooth; 3, half tooth; 4, cutting edge.
Embodiment
Please with reference to shown in Figure 1, Fig. 1 is the end view of micromotor rotor slot insulation paper shearing tool of the present invention.
In the present embodiment, a kind of micromotor rotor slot insulation paper shearing tool comprises handle of a knife 1 and cutter head, and said cutter head is arranged at an end of handle of a knife 1; Said handle of a knife 1 is the rectangle flat structure; Said cutter head is a zigzag structure, has three teeth altogether, and the centre is the whole tooth 2 of tool cutting edge 4; The both sides of said whole tooth 2 are half tooth 3; Said two and half teeth 3 are along middle whole tooth 2 symmetries, and the inboard of said two and half teeth 2 all has cutting edge 4, and the tooth root of said whole tooth 2 is wide, and to equal the grip hold arc of cylindrical between adjacent two grooves of rotor long.
The crown of said whole tooth 2 and half tooth 3 is 1cm to the length of tooth root.
In use; Two and half teeth 3 of cutter are put into respectively between the cylindrical of insulating paper and rotor core, and middle whole tooth 2 is placed on the cylindrical of rotor core, through 1 pair of cutter applied thrust of handle of a knife; Cutter head moves ahead along the periphery of rotor core, and the insulating paper with the rotor right ends cuts off simultaneously.The rotor of 1000 motor calculates by manufactory's every day; Every rotor is 24 grooves; Single operation is removed insulating paper needs 1S, need operate 3 times by the every groove of prior art, needs every day be altogether: 1000 * 24 * 3 * 1S=72000S time; Only need operate 1 time with every groove behind this little cutter, need the time to be merely every day altogether: 1000 * 24 * 1 * 1S=24000S.
It is original 1/3 that the activity time that above-mentioned micromotor rotor slot insulation paper shearing tool is removed micromotor slot liner paper shortens to, and improved labor productivity, alleviated working strength of workers, reduced the production cost of enterprise.
