Description

Technical Field

[0001] This utility model belongs to the technical field of starter assembly equipment, and relates to a starter rotor wiring device. Background Technology

[0002] Rotor threading is an important process in motor production. In China, the main production method is to cut and bend rolls of enameled wire into U shapes using small molds, and then manually split, twist, and insert the U-shaped wires into the rotor slots. Therefore, it is necessary to design rotor threading equipment to free up production capacity.

[0003] For example, the patent with authorization announcement number CN201985708U discloses an automatic U-bending non-destructive wire insertion machine for the production of enameled copper wire in automobile starter armatures. It consists of cylinder A, cylinder B, roller assembly, U-shaped mold, insertion rod, moving plate, left upright plate, and right upright plate. Cylinder B is installed between the left and right upright plates, and a fixed plate A is installed on cylinder B. The left and right upright plates are provided with a sliding groove A, and the moving plate is installed in the sliding groove A. The moving plate is provided with a sliding groove B, and an insertion rod guide block is fixedly installed on the moving plate. The U-shaped mold is installed below the guide block, and the insertion rod fixing block is installed above the guide block.

[0004] The aforementioned equipment can automatically assemble and connect the starter motor, but it still has some shortcomings: Metal shavings from processing often remain in the slots of the starter rotor. When a small amount of enameled copper wire is bent and pressed into the bottom of the slot, it interferes with the metal shavings, causing damage to the enamel film and affecting the reliability of the starter rotor. To improve these problems, those skilled in the art typically consider: 1. Cleaning away the processing debris inside the rotor slots with cleaning tools before connecting the wires; 2. Setting up a vibrating platform, placing the rotor slots downwards and vibrating it before connecting the wires to dislodge the metal shavings. Summary of the Invention

[0005] This utility model addresses the aforementioned problems in existing technologies by providing a starter rotor wiring device. The technical problem this utility model aims to solve is that the wiring reliability of existing devices is insufficient.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A starter rotor insertion device includes a mounting frame, on which a vertically movable lifting seat and a positioning turntable for placing the rotor are connected. The side of the lifting seat has a vertically shaped zigzag plate, which is located directly above the positioning turntable. A vertically arranged push rod that can move up and down relative to the lifting seat is also connected to the lifting seat. The push rod is characterized in that its lower end is a tubular shape with an open bottom, and its middle section has an air inlet hole communicating with the inner cavity of the push rod. The lower end of the push rod also has a chip blowing hole communicating with the inner cavity of the push rod. The chip blowing hole is arranged downward and outward. The zigzag plate has a vertically penetrating guide hole, and the inner wall of the guide hole has a vent hole communicating with the outer surface of the lifting seat. The push rod is vertically inserted into the guide hole. When the push rod extends out of the guide hole and moves downward to near the positioning turntable, the air inlet hole and the vent hole are connected.

[0008] The downward movement of the bending plate bends the enameled copper wire placed horizontally on the mounting bracket, ultimately forming a U-shape with the guide of the mounting bracket. Then, the push rod moves downward independently, pushing the bent enameled copper wire into the slot on the lower positioning turntable where the rotor is placed. The push rod is designed with a tubular lower end, and an air inlet connected to the tubular inner cavity is located on the outer periphery of the middle section. An inclined chip removal hole is also provided on the outer periphery of the lower end of the push rod, which is inserted into the guide hole of the bending plate. A vent hole connecting to the outer side of the lifting seat is provided on the inner wall of the guide hole to allow high-pressure gas to enter. This facilitates the downward movement of the push rod and drives the bent wire... Before the enameled copper wire is inserted into the bottom of the rotor slot, the air inlet and vent are connected, allowing the blow-off hole at the lower end of the push rod to spray air downwards from the bottom of the slot, blowing the metal shavings on the bottom surface of the slot to the corner. This avoids hard contact between the U-shaped bottom of the enameled copper wire and the metal shavings in the center of the bottom surface of the slot, thus preventing damage to the enamel film. At other stages, the vent port can be covered on the outer periphery of the push rod to avoid wasting air. At this time, the airflow sprayed from the open end of the push rod can push the enameled copper wire to separate from the push rod and move it into place, thus avoiding hard contact that would occur when the push rod presses the enameled copper wire into place and damage the enamel film, effectively improving the reliability of the rotor.

[0009] In the aforementioned starter rotor wiring device, the chip blowing hole is located on the side of the push rod away from the lifting seat. This fully utilizes the strip-shaped characteristics of the rotor slot cross-section, allowing the airflow ejected from the chip blowing hole to diffuse from the center of the slot cross-section and blow the metal chips to both ends, greatly reducing the probability of the metal chips coming into contact with the U-shaped enameled copper wire.

[0010] In the aforementioned starter rotor insertion device, several magnetic pillars are embedded in the lower outer periphery of the push rod. These magnetic pillars are all positioned below the blow-off hole. The bottom surface of the folding plate has a chip accumulation groove arranged around the lower port of the guide hole. The inner diameter of the chip accumulation groove is slightly larger than the radial dimension of the guide hole. This allows the magnetic pillars to attract some of the metal chips blown up by the airflow to the outer periphery of the push rod after the lower end of the push rod extends into the rotor slot, reducing the impact of metal chips in the slot and preventing them from falling back down. When the push rod retracts back into the guide hole, the attracted metal chips are scraped into the chip accumulation groove for storage, without affecting normal folding and insertion operations. Since the amount of attracted metal chips is usually small, the chip accumulation groove only needs to be cleaned periodically by the operator.

[0011] In the aforementioned starter rotor wiring device, the port connecting the vent hole and the guide hole is flared. This ensures a stable and reliable connection between the vent hole and the air inlet before the push rod moves down to its final position, thereby guaranteeing stable purging function.

[0012] In the aforementioned starter rotor wiring device, the mounting bracket includes two parallel upright plates, each with vertically arranged and symmetrically positioned strip-shaped holes. The lifting seat is slidably connected between the two upright plates. This arrangement allows the upright plates to guide and constrain the movement of the lifting seat, ensuring stable movement. The lower ends of the two strip-shaped holes provide stable support for the ends of any externally inserted enameled copper wires, enabling equivalent deformation at both ends of the enameled copper wires when the bending plate moves downwards, thus guaranteeing bending quality.

[0013] In the aforementioned starter rotor wiring device, a vertically positioned drive cylinder one is fixed on the mounting bracket, the lifting seat is fixed to the output end of the drive cylinder one, and a vertically downward-facing drive cylinder two is fixed to the top of the lifting seat. The upper end of the push rod is fixed to the output end of the drive cylinder two. The movement of the lifting seat and the push rod is achieved by drive cylinder one and drive cylinder two respectively, which helps to ensure operational stability while controlling costs.

[0014] In the aforementioned starter rotor wiring device, a horizontally positioned adjusting bracket with its outer end bent to one side in an L-shape is fixed to the outer side of one of the vertical plates. A horizontally arranged screw, perpendicular to the vertical plate, is threaded onto the adjusting bracket. A limiting block is rotatably fitted onto one end of the screw facing the vertical plate. The limiting block is positioned axially along the screw and opposite to the lower end of the strip-shaped hole. The limiting block can block the end of the enameled copper wire fed from the other side, ensuring that the middle section of the enameled copper wire is vertically aligned with the bottom of the folding plate to ensure uniformity of the folding line. Thus, when adapting to enameled copper wires of different lengths, the position between the limiting block and the vertical plate can be adjusted by rotating the screw, thereby improving applicability.

[0015] In the aforementioned starter rotor insertion device, the limiting block is square-shaped with one side always abutting against the side of the adjusting bracket. Two spaced-apart guide clips, shaped like vertical plates, are fixedly connected to the side of the limiting block closest to the vertical plate. This design ensures that the front end of the enameled copper wire is limited by the two guide clips after insertion, preventing the end of the enameled copper wire from shifting and guaranteeing bending and insertion effectiveness.

[0016] In the aforementioned starter rotor insertion device, the middle of the opposite sides of the two guide clips arches inward, forming a gap that allows only the enameled copper wire to pass through. This confines the end of the enameled copper wire within a smaller space after it is inserted between the two guide clips, further ensuring the positional accuracy of the wire and preventing excessive displacement of the wire end during bending, which could lead to collision and displacement with the upright plate.

[0017] In the aforementioned starter rotor wiring device, each of the two opposing upright plates has a protruding mounting plate. Each mounting plate, on the side opposite to the lifting seat, is rotatably connected to a row of vertically arranged guide rollers. The axis of each guide roller is horizontally aligned and parallel to the bend plate, which is located between the two rows of guide rollers. This allows the outer side of the enameled copper wire to contact the outer circumference of the guide rollers during bending, converting the frictional resistance encountered during downward movement into rolling friction, resulting in less resistance and smoother operation. Furthermore, it prevents damage to the enamel film on the guide roller surface, improving reliability.

[0018] In the aforementioned starter rotor insertion device, the outer circumference of each guide roller has an annular inner groove. This allows the enameled copper wire to be positioned within the groove, preventing positional deviations during bending and downward movement that could affect the normal insertion of the enameled copper wire.

[0019] Compared with the prior art, the advantages of this utility model are as follows:

[0020] This starter rotor insertion device can clean the metal shavings on the bottom of the slot to an area that does not come into contact with the enameled copper wire before inserting it into the bottom of the slot of the starter rotor after bending the copper wire. This avoids local damage to the enamel film at the bottom of the copper wire. At the same time, the contact point between the copper wire and the push rod will not be subjected to excessive pressure when the copper wire is pressed into place, effectively ensuring assembly reliability.

When the push rod 4 extends out of the guide hole 211 and moves downward to near the positioning turntable 3, the air inlet 41 and the vent hole 212 are connected. The chip-blowing hole 42 is located on the side of the push rod 4 away from the lifting seat 2. Multiple magnetic pillars 43 are embedded on the lower outer periphery of the push rod 4.

Each of the two upright plates 11 has a protruding mounting plate 112 on its opposite side. Each mounting plate 112 is rotatably connected to a row of vertically arranged guide rollers 102 on the side away from the lifting seat 2. The guide rollers 102 are not higher than the lower end of the strip hole 111. The axis of the guide rollers 102 is set horizontally and is parallel to the folded plate 21. The folded plate 21 is located between the two rows of guide rollers 102. The outer periphery of each guide roller 102 has an annular inner groove 1021.

[0038] like Figure 1-3The aforementioned adjustment bracket 7 is horizontally mounted on the outer side of a vertical plate 11, with its outer end bent to one side in an L-shape. A horizontally arranged screw 8, perpendicular to the vertical plate 11, is threaded onto the adjustment bracket 7. A limiting block 9 is rotatably fitted onto one end of the screw 8 facing the vertical plate 11. The limiting block 9 is positioned opposite the lower end of the slotted hole 111 along the axial direction of the screw 8. The limiting block 9 is square-shaped, with one side always abutting against the side of the adjustment bracket 7. Two spaced-apart, vertically plate-shaped guide clips 101 are fixedly connected to the side of the limiting block 9 closest to the vertical plate 11.
