Description

Technical Field

[0001] The utility model relates to the field of rotor manufacturing, in particular to a rotor twisting tool. Background Art

[0002] The motor is used in important components such as starters and transmission cases. The rotor is the most critical component of the motor, and the rotor includes a rotating shaft, armature winding, commutator, etc. The winding lead wire ends on the armature winding need to correspond one-to-one and be connected to the commutator segments on the commutator. The commutator segments will be provided with slots that are compatible with the winding lead wire ends. The winding lead wire ends need to be inserted into the corresponding slots one by one, and the slots are evenly distributed around the circumference, and the winding lead wire ends will be placed at the opening of the slots. At this time, they need to be knocked in manually, which is very inefficient. Utility Model Content

[0003] In order to solve the above problems, the purpose of the present invention is to provide a rotor twisting tool that can reliably and simultaneously insert the winding lead-out wire ends into the commutator segment slots, thereby improving production efficiency.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a rotor twisting head tooling, comprising a torsion plate, a radial slider, a fixed guide plate and a sealing plate, the torsion plate being driven to rotate by a motor, the torsion plate being provided with guide grooves uniformly distributed circumferentially and radially arranged, each guide groove being provided with the radial slider, the radial slider being provided with a plug-in pressure rod with a "V"-shaped end facing the inner end, the edge position of the fixed guide plate being provided with an inclined guide groove uniformly distributed circumferentially, the inclined guide groove being provided with a movable guide column, the guide column being connected to the radial slider, the sealing plate being connected to the upper end face of the fixed guide plate, and the sealing plate being provided with a positioning groove.

[0005] The inner side wall of the torsion plate is provided with circumferentially evenly distributed limiting grooves, and the positions between the limiting grooves are connected with guide blocks. The side walls of the guide blocks are arranged along the radial direction of the torsion plate, and the intervals between the guide blocks form the guide grooves.

[0006] The lower end of the torsion plate is connected to the transmission plate, the upper end of the transmission plate is provided with a rotor positioning groove, and a driving plate is provided below the transmission plate. A transmission ring is provided on the driving plate, and the peripheral wall of the transmission ring is provided with vertically arranged convex teeth. A card slot matching the convex teeth is provided on the inner hole wall of the transmission plate. The driving plate is connected to the transmission plate through the concave-convex fitting of the convex teeth and the card slot, and the driving plate is connected to the output shaft of the motor.

[0007] The beneficial effects of the present invention are as follows: the sealing plate is fixed by the concave-convex fit of the positioning groove on the sealing plate, so that the fixed guide plate is fixed, and after the rotor of the twisting head is placed in the twisting plate, the commutator slot and the insertion pressure rod are aligned one by one, and after the motor drives the twisting plate to rotate, the guide column will move along the guide groove on the fixed guide plate, so that the radial slider can be driven to extend and retract radially along the guide groove. When the radial slider moves inward, it will drive the insertion pressure rod to be inserted into the commutator slot, so that the winding lead wire end at the commutator slot opening can be inserted into the commutator slot, so that the commutator segment and the winding lead wire end are pressed into one. The tooling can effectively improve the production efficiency of the rotor twisting operation and has a reliable structure.

[0012] The present invention is described in detail below through examples, which are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention.

[0013] like Figure 1 — Figure 3 As shown, this embodiment discloses a rotor twisting head tooling, including a torsion plate 1, a radial slider 2, a fixed guide plate 3 and a sealing plate 4. The torsion plate 1 is driven to rotate by a motor. The torsion plate 1 is provided with guide grooves 5 that are evenly distributed around the circumference and radially arranged. A radial slider 2 is provided in each guide groove 5. The radial slider 2 is provided with a pressure rod 21 with a "V"-shaped end at the inner end. The edge position of the fixed guide plate 3 is provided with an inclined guide groove 31 that is evenly distributed around the circumference. A movable guide column 6 is provided in the inclined guide groove 31, which is connected to the radial slider 2. The sealing plate 4 is connected to the upper end surface of the fixed guide plate 3. A positioning groove 41 is provided on the sealing plate 4. The positioning groove 41 can be positioned in conjunction with the concave and convex parts of the component to position the fixed guide plate 3.

[0014] The inner sidewall of the torsion plate 1 is provided with limiting grooves 11 evenly distributed around the circumference. These limiting grooves 11 are used to limit the movement of the radial slider 2. Guide blocks 7 are connected between the limiting grooves 11. The guide blocks 7 are equilateral triangles, with the sidewalls of the guide blocks 7 arranged in the radial direction of the torsion plate 1. The gaps between the guide blocks 7 form guide grooves 5. This structure ensures smoother sliding of the radial slider 2 along the guide grooves 5 and a more reliable structure.

[0015] The lower end of the torsion plate 1 is connected to a transmission plate 8. The upper end of the transmission plate 8 is provided with a rotor positioning slot. The rotor to be twisted is inserted into the rotor positioning slot for positioning, thereby quickly aligning the commutator slot and the insertion pressure rod 21. A drive plate 9 is provided below the transmission plate 8. The drive plate 9 is provided with a transmission ring 91. The peripheral wall of the transmission ring 91 is provided with vertically arranged protruding teeth. The inner hole wall of the transmission plate 8 is provided with a slot that matches the protruding teeth. The drive plate 9 is connected to the transmission plate 8 through the concave-convex fitting of the protruding teeth and the slot. The drive plate 9 is connected to the output shaft of the motor. This structure not only ensures that the transmission of the torsion plate 1 is more reliable, but also ensures reliable positioning of the rotor.

[0016] By adopting the above technical solution, the sealing plate 4 is fixed by the positioning groove 41 on the sealing plate 4 through the concave-convex fit, so that the fixed guide plate 3 is fixed. After the twisted rotor is placed in the torsion plate 1, the commutator slot and the insertion rod 21 are aligned one by one. After the motor drives the torsion plate 1 to rotate, the guide column 6 will move along the guide groove 5 on the fixed guide plate 3, so that the radial slider 2 can be driven to extend and retract radially along the guide groove 5. When the radial slider 2 moves inward, it will drive the insertion rod 21 to be inserted into the commutator slot, so that the winding lead wire end at the opening of the commutator slot can be inserted into the commutator slot, so that the commutator and the winding lead wire end are pressed into one. This tooling can effectively improve the production efficiency of the rotor twisting operation and has a reliable structure.

[0017] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.
