Description

Technical Field

[0001] The utility model relates to the field of coil shaping machines, in particular to an intermediate shaping machine for stator coil extrusion. Background Art

[0002] Motor stator windings are typically manually inserted, leaving the ends of the stator windings somewhat untidy. To ensure the coils' precise shape after installation, a winding shaping device is typically required to shape the coils. Currently, most motor stator windings are manually shaped, which can lead to loose windings after winding inside the stator, causing the wire bundle to extend beyond the stator, hindering subsequent processing and installation. Therefore, shaping is required in the center of the stator winding. Utility Model Content

[0003] The purpose of the present utility model is to provide an intermediate shaping machine for stator coil extrusion, so as to solve the problem that the motor stator coil is mostly shaped manually in the above-mentioned background technology, and the coil tends to become loose after being wound inside the stator, causing the wire bundle to extend into the inside of the stator, thereby affecting subsequent processing and installation. Therefore, it is necessary to perform shaping processing on the middle of the stator coil.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an intermediate shaping machine for stator coil extrusion, comprising: a processing table, a pushing assembly and a shaping assembly;

[0005] Wherein: a mounting plate is fixedly installed on one side of the processing table, and a fixing plate is installed on the top of the mounting plate;

[0006] The pushing assembly includes an electric push rod installed on the top of the fixed plate, a pushing frame is installed on the telescopic end of the electric push rod, a guide rod is installed on one side of the bottom of the fixed plate, and one side of the pushing frame slides on the surface of the guide rod;

[0007] The shaping assembly comprises a first electric hydraulic cylinder installed in the middle of the pushing frame. The telescopic end of the first electric hydraulic cylinder passes through the pushing frame and is fixedly mounted with a shaping rod. The end of the shaping rod is connected with a conical head.

[0008] As a preferred solution of the present invention: a placement seat is installed in the middle of the surface of the processing table, a stator coil is placed on the surface of the placement seat, support seats are installed on both sides of the surface of the processing table, two pneumatic push rods are fixedly installed on the top of the support seat, and fixed blocks are installed at the telescopic ends of the two pneumatic push rods, and the fixed blocks are fixed on both sides of the stator coil.

[0009] As a preferred solution of the present invention: a second electric hydraulic cylinder is fixedly mounted on the surface of the pushing frame, a limiting ring is fixedly mounted on the telescopic end of the second electric hydraulic cylinder, and the limiting ring is in contact with the top of the stator coil.

[0010] As a preferred solution of the present invention: a displacement sensor is fixedly installed on the surface of the pushing rack.

[0011] As a preferred solution of the present utility model: the displacement sensor corresponds to the telescopic end of the first electric hydraulic cylinder.

[0012] As a preferred solution of the present invention: a switch panel is fixedly installed on one side of the mounting plate, the electric push rod, the first electric hydraulic cylinder, the second electric hydraulic cylinder, the pneumatic push rod and the displacement sensor are all electrically connected to the switch panel, and the switch panel is electrically connected to an external power supply.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] (1) An electric push rod is installed on the top of the fixed plate. When the electric push rod is extended, it drives the push rack to move. The push rack slides on the surface of the guide rod at the bottom of the fixed plate, so that the push rack maintains stable lifting and lowering movement. The push rack drives the surface-mounted shaping component to shape the stator coil;

[0015] (2) The pushing frame approaches the stator winding package under the push of the electric push rod, and the first electric hydraulic cylinder extends to drive the shaping rod to move into the inside of the stator winding package. The conical head at the end of the shaping rod is first inserted into the inside of the stator winding package, which makes it easy to push the scattered wire bundles extending into the inside of the stator into the wire grooves on the surface of the stator. The wire bundles are sorted by the shaping rod to ensure that the wire bundles are neat. The surface of the pushing frame is fixed with a second electric hydraulic cylinder. The second electric hydraulic cylinder drives the limiting ring to contact the stator winding package first, so that the top wire bundle is fixed by the limiting ring to avoid the stator winding package from being offset during shaping.
