Description

Motor stator wire binding machine

Technical Field

The utility model belongs to the technical field of motor production, and particularly relates to a motor stator wire binding machine.

Background

One of the processes in the production of the motor stator is to bind a plurality of groups of coils embedded in the stator slots, so that the coils are prevented from vibrating due to electromagnetic force in the starting and running processes of the motor. And the binding process is completed by three actions of the wire binding machine: the wire binding machine is used for binding wires on the upper and lower crochet hooks on the stator coil to advance and retreat; secondly, the upper crochet hook and the lower crochet hook move up and down; and thirdly, the upper crochet hook and the lower crochet hook or the stator rotate at a certain angle (so as to finish the whole circle binding). The three movements finish the actions of hooking and binding according to a certain corresponding relation.

The chinese patent document with publication No. CN219268686U discloses a motor stator binding machine, which connects a first fastening rod with one end fixed with a second fastening rod with one end capable of lifting after the rotation of an adjusting rod, so as to synchronously complete the adjustment of the horizontal positions of the other ends of the two fastening rods by controlling the rotation of the adjusting rod, thereby enabling the end of the fastening rod to abut against the inner wall of the stator, so as to complete the fixation of stators with different sizes.

However, in the prior art, when the end of the fastening rod abutting against the inner wall of the stator moves horizontally according to the inner diameter of the stator, the fastening rod also moves in the vertical direction, so that each fastening rod with a fixing function has the defect that the fastening rod cannot contact with the inner wall of the stator or the contact part can affect the normal binding wire at the same time.
