Gear Transmission Mechanism Used in Indexing Part of Single Coordinate Sector Punching Machine

Abstract

The invention discloses a gear drive mechanism for an indexing part of a single coordinate fan-shaped notching machine. The gear drive mechanism comprises an indexing seat and a servo motor. The indexing seat is provided with an indexing spindle, a fan-shaped indexing device is arranged at the top of the indexing spindle, a P4-gear is arranged at the end of the indexing spindle. The servo motor is arranged on the servo motor base which is fixed on the indexing seat. The output shaft of the servo motor is drivingly connected with a P1-gear, a P2- forceps gear and a P3-gear. The P2-gear is fixedly arranged at the axis of the P3-gear, the axle of the P3-gear is arranged on the housing of an intermediate shaft, and the housing of the intermediate shaft is arranged at the indexing seat. The P4-gear is engaged with the P3-gear, the P1-gear is engaged with the P2-gear. The gear drive mechanism has the advantages of high driving accuracy, low cost and compact structure. The notching requirement of a fan-shaped piece is met, and at the same time, the punching requirement of a round-shaped piece is met with no fan-shaped indexing device used.

Description

technical field [0001] The invention relates to the field of notching machines for motor iron chip processing equipment, in particular to a gear transmission mechanism for the indexing part of a single-coordinate fan-shaped notching machine. Background technique [0002] The punching machine is a special equipment for single-slot punching used for punching the slot holes of the motor rotor or stator core. The punching die for punching the motor rotor or stator core sheet is installed between the punch (slider) and the worktable, and the upper die is driven to reciprocate up and down through the up and down reciprocating movement of the punch (slider). The iron chip (punching sheet) that needs to be punched is installed on the sector indexing device with intermittent movement, and the iron chip (punching sheet) is rotated according to the preset requirements through the sector indexing device. When the punch (slider) moves downward, the iron chip (punching piece) does not ro...

Problems solved by technology

The single-coordinate fan-shaped notching machine with this kind of transmission structure requires higher precision grades of worm gears and worms, low transmission efficiency, high cost, and low punching times.

As far as the current domestic market is concerned, it is relatively difficult to purchase high-precision worm gears and worms, and the price is very high
