Bunch cutting-off apparatus of stator automatic wire binding machine

Abstract

The invention discloses a bunch cutting-off apparatus of a stator automatic wire binding machine. The bunch cutting-off apparatus comprises an L-shaped bracket; a cutting-off groove is formed in the top surface of the bracket; a clamping block is inserted and connected in the cutting-off groove; a through groove is formed in the clamping block; a pair of hinged grooves are formed in the opposite side walls of the through groove; a rotary shaft is hinged in the hinged grooves; a driving gear is inserted and fixed on the rotary shaft in the through groove in a sleeving manner; torsional sleeves are inserted on the rotary shaft on the two sides of the driving gear in a sleeving manner; the two ends of the torsional springs are fixed on the rotary shaft and the inner walls of the corresponding hinged grooves; a rack part is formed on the inner wall at the lower end of the cutting-off groove; the rack part and the driving gear are meshed up and down; an inserting groove is formed in one side edge of the side wall, close to the cutting-off groove, of the clamping block; a blade is inserted and connected in the inserting groove; a buckling tooth is formed on the side wall of the clamping block on one side of the inserting groove; and a tooth groove matched with the buckling tooth is formed in the side wall of the cutting-off groove. By adoption of the bunch cutting-off apparatus, a bunch can be cut off rapidly and the clamping force of the cut bunch can be reinforced, so that separating of a bunch end in the wire hooking process can be avoided.

Description

[0001] Technical field: [0002] The invention relates to the technical field of automation equipment, in particular to a wire harness cutting device of a stator automatic wire binding machine. [0003] Background technique: [0004] Stator automatic wire binding machine is a mechanical device that automatically binds wires to motor stator windings, and is an important automation device for automatic stator assembly production line. After the stator wire binding of one stator is completed on the existing stator wire binding machine, it is necessary to cut the wire harness used for the wire binding to facilitate the wire binding of the next stator. Existing cutting devices such as figure 1 As shown, the structure is simple, with only one vertical clamping strip 7, a vertical clamping slot 71 is formed on the clamping strip 7, and the top of the clamping slot 71 is formed with a flaring 72 connected to the top of the clamping strip 7. The clamping slot 71 The clip 7 at the location is...

Problems solved by technology

Existing cutting devices such as figure 1 As shown, its structure is simple, there is only one vertical clip 7, and a vertical clip 71 is formed on the clip 7, and the top of the clip 71 is formed with a flaring 72 connected to the top of the clip 7, and the clip 71 The clip 7 at the center is fixedly connected with a cutting knife 9 through a screw 8. When cutting, the wire hook device hooks the beam into the slot 71 of the clip 7 and pulls the wire to cut off. The thread end is clamped on the clip of the clip 7 In the slot 71, the wire binding of the next stator is realized by hooking the wire with the hooking device, but the clamping force of the slot 71 on the clip 7 is small, and the thread ends of the wires are easy to break away from the clip 7 during the hooking process. , then the wire binding of the next stator cannot be completed
