Problems solved by technology
[0002] When the existing thread inserting machine is hanging the thread, the cross-section shape of the inner and outer needle bars of the universal thread fork is a circular cross section, but when it encounters a thin and thick stator (the stack thickness is less than 30mm), the thread fork is tilted on the guide finger, causing the thread to hang. difficulty

Embodiment Construction
[0008] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings. refer to figure 1 , figure 2 . A wire fork positioning device for thin-stacked and thick stator inlaid wires, which is characterized in that: after the handle 5 is fastened to the wire fork plate 4 with screws, the needle bar 2 and the positioning bar 3 in the inner layer are screwed according to the position of the sectional view. Fasten in the corresponding groove of wire fork disc 4, and then outer needle bar 1 is fastened in the corresponding hole of the outer layer of wire fork disc 4 with screws.
[0009] Working principle: When using the thread fork with positioning rod, since the convex surface of the positioning rod is inserted into the gap of the guide finger, the "L" surface of the positioning rod is effectively positioned on the guide finger, so the thread fork will not tilt on the guide finger, and the thread hangi...

The invention discloses a coil fork positioning device for coil inserting and hanging in terms of a small-lamination-thickness rotor. The positioning device is characterized in that after a handle is tightened to a coil fork disc through screws, an inner-layer inner needle rod and a positioning rod are tightened into a groove corresponding to the coil fork disc through screws according to the position of a profile, and then an outer needle rod is tightened into an outer-layer hole corresponding to the coil fork disc. The positioning device is suitable for coil inserting in terms of small-lamination-thickness rotors; because small-lamination-thickness guide finger hung coils are short, coil forks with universal shapes incline on guide fingers when used for hanging coils, and coil hanging is difficult; by adopting coil forks with positioning rods, because protruding faces of the positioning rods are inserted into guide finger seams and L-shaped faces of the positioning rods are effectively positioned to guide fingers, the coil forks will not incline on the guide fingers, coil hanging is easy, coil hanging time is shortened, and coil inserting efficiency is improved.
Description
technical field [0001] The invention belongs to the technical field of electrical machinery, and in particular relates to a wire fork positioning device when thin-stacked and thick stators are embedded with wires and hung up. Background technique [0002] When the existing thread inserting machine is hanging the thread, the cross-section shape of the inner and outer needle bars of the universal thread fork is a circular cross section, but when it encounters a thin and thick stator (the stack thickness is less than 30mm), the thread fork is tilted on the guide finger, causing the thread to hang. difficulty. Contents of the invention [0003] The object of the present invention is to provide a wire fork positioning device when the thin-stacked stator inserts the wire and hangs the wire. [0004] The invention relates to a wire fork positioning device for thin-stacked and thick stator embedded wires and hanging wires. Fix it in the corresponding groove of the wire fork, and...
