Description

Technical Field

[0001] The invention relates to motor stator wire auxiliary processing equipment, in particular to a motor stator wire expanding device for new energy vehicles. Background Art

[0002] New energy motors usually refer to motors used in electric vehicles, wind power generation and other fields, so the stator wire should refer to the wire used for stator windings. As the core component of the motor, the stator is responsible for generating the magnetic field, so the selection and design of the stator wire is crucial to the performance of the motor.

[0003] The wire of the outermost circle of the electronic coil needs to be bent outward to expand the wire. Currently, the wire is bent manually based on experience, resulting in the accuracy of the bent wire harness cannot be guaranteed, affecting the performance of the motor after production.

[0004] In view of the above-mentioned defects, the designer actively conducts research and innovation in order to create a motor stator expansion device for new energy vehicles to make it more valuable for industrial use. Summary of the invention

[0005] In order to solve the above technical problems, an object of the present invention is to provide a motor stator expansion device for new energy vehicles.

[0006] A motor stator wire expanding device for new energy vehicles of the present invention comprises a mounting ring in contact with a motor housing, the mounting ring is provided with an inwardly concave annular slide groove, a rotating block is inserted into the slide groove, the rotating block is provided with two guide columns extending beyond the upper edge of the mounting ring, a lifting and movable support plate is mounted on the guide column, a pull head is provided on the support plate and can move forward and backward, and a through hole is provided at the front end of the pull head and is sleeved on the stator wire.

[0007] This motor stator wire expansion device for new energy vehicles is installed on the stator wire through a pulling head. The pulling head moves backward to complete the expansion operation of the stator wire. The pulling head can slide on the mounting ring and can be moved to any position on the mounting ring, which is convenient for the expansion operation of each wire.

[0008] Furthermore, the inner upper edge of the mounting ring is a limiting ring bent inwardly, the bottom is a supporting ring, the outer side is a retaining ring, the limiting ring and the inner side of the retaining ring are mirror-image grooves, and the rotating block is inserted into the groove.

[0009] The mounting ring is composed of a limit ring, a support ring and a retaining ring, and the groove inside the mounting ring is used for the rotating block to facilitate the installation and sliding of the rotating block.

[0010] Furthermore, guide sleeves are inserted into the through holes at both ends of the support plate, and the guide sleeves are mounted on the guide posts, and the top ends of the guide posts are blocked by outward protrusions.

[0011] The support plate and the guide column are slidably assembled so that the support plate can be moved up and down, which is convenient for adjusting the height of the pull head and convenient for the pull head to be put on the stator wire.

[0012] Furthermore, there are two parallel upwardly protruding support blocks in the middle of the support plate, and two rotating shafts are movably installed on the pull head and the support block. Support rods are movably installed on the two rotating shafts on the front side, and pull rods are movably installed on the two rotating shafts on the rear side.

[0013] The support block and the pull head are coordinated by the support rod on the front side and the pull rod on the rear side. The support rod and the pull rod form a parallelogram through multiple rotating shafts and between the support block and the pull head. After pulling the pull rod, the pull head can be controlled to move obliquely backward to complete the wire expansion operation.

[0014] Furthermore, the tail end of the pull head is provided with two screw holes, and the adjusting bolts are screwed into the screw holes.

[0015] The two adjusting bolts at the tail end of the pull head can contact the rear side of the pull rod to limit the swing position of the lower end of the pull rod, thereby serving the purpose of auxiliary positioning.

[0016] Through the above scheme, the present invention has at least the following advantages: the pull head of the motor stator wire expanding device for new energy vehicles can be moved to any position in the mounting ring, which is convenient for the pull head to be connected with the stator wire that needs to be bent, and the pull head can move up and down, which is convenient for being put on the stator wire, and the distance that the pull head moves forward and backward is controllable, ensuring that the arc distance of each bend is consistent, meeting the needs of precise wire expansion.

DETAILED DESCRIPTION

[0020] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0021] See also Figure 1 The mounting ring 1 of the motor stator wire expansion device for new energy vehicles is a ring structure with a through middle, which can be sleeved on the motor housing. There is a slide groove in the mounting ring 1, and this slide groove is used to install the rotating block 2. The rotating block 2 can move in the slide groove under the drive of external force. There are two vertical guide pillars 3 on the rotating block 2. The support plate 4 is sleeved on the guide pillars 3, so that the support plate 4 can be lifted and lowered on the guide pillars 3. The pull head 5 installed on the support plate 4 is a movable structure that can move forward and backward. The through hole at the end of the pull head 5 can be sleeved on the wire. After the pull head 5 moves backward, the external expansion operation of the motor stator wire can be completed.

[0022] See also Figure 2 The mounting ring 1 includes a limiting ring 6, a supporting ring 7 and a retaining ring 8. The supporting ring 7 is located at the bottom. The limiting ring 6 and the retaining ring 8 are fixed to the supporting ring 7 with bolts. There are mirror-image grooves on the outer side of the limiting ring 6 and the inner side of the retaining ring 8. This groove is used for the rotating block 2 to be inserted. When assembling, first insert the rotating block 2 into the groove on one side of the retaining ring 8, and then insert the other side of the rotating block 2 into the outer groove of the limiting ring 8 by tilting the limiting ring 8, and then fix the limiting ring 6 and the retaining ring 8 on the supporting ring 7 to complete the installation. The limiting ring 6 is bent inward and is used to be mounted on the upper edge of the stator housing of the motor.

[0023] See also Figure 3 In order to facilitate the up and down movement of the support plate 4, guide sleeves are installed in the through holes on both sides of the support plate 4 by interference fit. The guide sleeves are sleeved on the guide pillars 3, so that the support plate 4 can be lifted and moved. At the same time, there is a blockage at the top of the guide pillars 3 to prevent the support plate 4 from slipping off the guide pillars 3.

[0024] See also Figure 3There are two support blocks 9 in the middle of the support plate 4, and there is a gap between the support blocks 9. At the same time, the middle of the slider 5 is also hollow. Two rotating shafts 10 are installed on the support block 9 and the slider 5. A support rod 11 is movably installed on the front end of the rotating shaft, and a pull rod 12 is movably installed on the rear end of the rotating shaft 10. After this installation method, the support block 9, the slider 5, the support rod 11 and the pull rod 12 form a parallelogram through the four rotating shafts 10. After pulling the pull rod 12, the slider 5 can be moved forward and backward, which is convenient for bending the wire.

[0025] The tail end of the pulling head 5 has two adjusting bolts screwed into the screw holes, and the two adjusting bolts are located on the upper and lower sides of the inner rotating shaft 10 of the pulling head 5. The adjusting bolt at the lower end can contact the lower end of the pull rod 12, and the adjusting bolt at the upper end can contact the lower middle part of the pull rod 12. The relative position of the adjusting bolt after the depth is adjusted can be used to limit the maximum position of the pull rod 12 deflection forward and backward. When it is necessary to take the stator wire, the pull rod 12 moves forward, and the lower end of the pull rod 12 contacts the adjusting bolt on the lower side. At this time, the maximum depth position of the pulling head 5 is limited. By adjusting the position of the adjusting bolt on the lower side, the through hole on the pulling head 5 and the wire are located on the same axis, which is convenient for taking. By adjusting the relative position of the adjusting bolt on the upper side, it is used to limit the maximum position of the pull rod 12 rotating backward, limit the distance that the pulling head 5 moves backward, ensure that the moving distance of the pulling head 5 is constant each time, and then facilitate the completion of precise wire bending and expansion operations.

[0026] The working principle of the present invention is as follows: When using this motor stator wire expansion device for new energy vehicles, first, the mounting ring 1 is sleeved on the motor stator housing, and the adjusting bolts on the lower and upper sides are adjusted according to the bending process and the relative position of the stator wire to limit the maximum forward and backward movement distance of the pull head 5. After the adjustment is completed, the pull rod 12 of the device is held to rotate the rotating block 2 in the mounting ring 1, and the pull head 5 is aligned with one of the wires. The pull rod 12 is lifted upward to move the pull head 5 upward, and then the pull rod 12 is pushed forward to align the through hole at the front end of the pull head 5 with the wire, and then the pull head 5 is moved down and the pull rod 12 is pulled backward to complete the bending operation of the wire. Finally, the pull head 5 is controlled to move upward to separate the pull head from the wire.

[0027] This cycle is repeated to complete the bending and flaring operations of all wires.
