Description

Technical Field

[0001] This utility model belongs to the field of motor parts processing technology, and in particular relates to an IPIN insertion fixture with automatic clamping to prevent scratching copper wires. Background Technology

[0002] An electric motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. It mainly includes electric motors and generators. An electric motor is a device that converts electrical energy into mechanical energy, while a generator converts mechanical energy into electrical energy. An i-pin winding is a type of motor winding that involves directly inserting flat copper wire into the stator slots and welding it at both ends.

[0003] To facilitate the transfer of multiple sets of flat copper wires forming i-pin windings into the stator slots, an insertion fixture is needed to pre-insert the multiple sets of flat copper wires in a ring. However, the existing insertion fixture does not have a top-fixing structure, which makes the flat copper wires easy to shake when inserted inside the fixture, resulting in positional movement. This directly affects the subsequent robot's ability to pick up and transfer the multiple sets of flat copper wires as a whole. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides an IPIN insertion fixture with automatic clamping to prevent scratching of copper wires. This solves the problem that the lack of a top fixing structure causes the flat copper wires to easily shake when inserted into the fixture, resulting in positional movement, which in turn directly affects the subsequent robot's ability to pick up and transfer multiple sets of flat copper wires as a whole.

[0005] This utility model is implemented as follows: an IPIN insertion fixture with automatic clamping and anti-scratch copper wire includes a bottom support plate and a base set on the bottom support plate. A column is fixed at the center of the top of the base, and a top plate is fixed at the top of the column. Multiple sets of positioning slots for inserting flat copper wires are evenly opened on the top plate, and multiple sets of top fixing components that cooperate with the flat copper wires are evenly arranged on the surface of the top plate.

[0006] As a preferred embodiment of the present invention, the top-fixing assembly includes multiple sets of placement blocks evenly arranged on the surface of the top plate, with a plunger inserted into each placement block. Multiple sets of square holes are opened on the surface of the top plate, with one end of the plunger passing through the square hole and extending into the positioning groove. A fixing sleeve is fixed to the top of each placement block and one end of the plunger, and a spring is engaged in the two adjacent sets of fixing sleeves.

[0007] As a preferred embodiment of this invention, each set of plungers has a chamfered top at one end of the positioning groove.

[0008] As a preferred embodiment of this utility model, each set of placement blocks has a positioning hole on the side away from the top plate for the locking bolt to pass through, and the surface of the top plate has multiple sets of screw holes that are threadedly connected to the locking bolt.

[0009] As a preferred embodiment of this utility model, each set of placement blocks has two sets of positioning rods symmetrically fixed at the bottom of the side near the top plate, and the surface of the top plate is provided with mounting holes for use with the positioning rods.

[0010] As a preferred embodiment of this invention, one side of the top of the inner cavity of each group of positioning grooves has an inclined structure.

[0011] As a preferred embodiment of this utility model, the base is provided with multiple sets of placement slots that cooperate with the positioning slots.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention, by setting up a top-fixing component and utilizing the elastic rebound of a spring, not only provides a certain supporting force for the plunger but also allows the plunger a certain amount of movable space. This ensures that when the flat copper wire is inserted into the positioning slot, a continuous top-fixing force is applied to the flat copper wire, enabling rapid positioning of the flat copper wire. This effectively prevents the flat copper wire from shaking when inserted into the tooling, avoiding positional movement that could affect the subsequent robot's ability to carry out and transfer multiple sets of flat copper wires as a whole. Furthermore, the component adopts a modular structure, facilitating the disassembly and replacement of individual parts, further improving the overall functionality of the insertion tooling.

[0020] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0021] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1 to 4 As shown in the figure, the present invention provides an IPIN insertion fixture with automatic clamping and anti-scratch copper wire, including a bottom support plate 1 and a base 2 disposed on the bottom support plate 1. A column 4 is fixed at the center of the top of the base 2, and a top plate 5 is fixed at the top of the column 4. Multiple positioning slots 6 for inserting flat copper wires are evenly opened on the top plate 5. Multiple sets of top fixing components that cooperate with the flat copper wires are evenly arranged on the surface of the top plate 5. By setting the top fixing components, a top fixing force can be continuously applied to the flat copper wires, and the flat copper wires can be quickly positioned. This can effectively prevent the flat copper wires from shaking when inserted into the insertion fixture, and prevent positional movement from affecting the subsequent robot to pick up and transfer multiple sets of flat copper wires as a whole. Moreover, the components adopt a modular structure, which facilitates the disassembly and replacement of each component, further improving the overall functionality of the insertion fixture.

[0023] As a preferred embodiment of this utility model, the top-fixing component includes multiple sets of placement blocks 7 evenly arranged on the surface of the top plate 5. A plunger 10 is inserted into the placement block 7. Multiple sets of square holes 15 are opened on the surface of the top plate 5. One end of the plunger 10 passes through the square hole 15 and extends into the positioning groove 6. A fixing sleeve 11 is fixed to the top of one end of the placement block 7 and the plunger 10. A spring 12 is snapped into the two adjacent sets of fixing sleeves 11. The design of the spring 12 can continuously provide a top-fixing force to the flat copper wire, which facilitates the quick clamping and positioning of the flat copper wire and prevents the flat copper wire from shaking when inserted into the positioning groove 6. At the same time, the spring 12 adopts a snap-fit ​​method, and the plunger 10 is directly inserted into the placement block 7, which makes it convenient for users to replace and maintain the internal equipment of the component.

[0024] As a preferred embodiment of this utility model, each set of plungers 10 has a chamfer on the top of one end of the positioning groove 6. The chamfer design can protect the insulating varnish layer of the flat copper wire, avoid damage to the insulating varnish layer of the flat copper wire, and prevent it from affecting the normal use of the flat copper wire.

[0025] As a preferred embodiment of this utility model, each set of placement blocks 7 has a positioning hole 8 on the side away from the top plate 5 for the locking bolt to pass through. The surface of the top plate 5 has multiple sets of screw holes 9 that are threadedly connected to the locking bolt. The design of the positioning hole 8 and the screw hole 9 makes it easy to quickly install and position the placement block 7 using the external locking bolt, and also facilitates disassembly later, thus improving the overall functionality of the device.

[0026] As a preferred embodiment of this utility model, each set of placement blocks 7 has two sets of positioning rods 14 symmetrically fixed at the bottom of the side near the top plate 5. The surface of the top plate 5 is provided with mounting holes 13 that cooperate with the positioning rods 14. The design of the positioning rods 14 and the mounting holes 13 allows the placement blocks 7 to be pre-positioned during assembly, which facilitates quick assembly and improves the assembly speed of the placement blocks 7.

[0027] As a preferred embodiment of this invention, one side of the top of the inner cavity of each positioning groove 6 is inclined, which facilitates the quick guidance of the flat copper wire into the positioning groove 6 and improves the insertion speed of the flat copper wire.

[0028] As a preferred embodiment of this utility model, the base 2 is provided with multiple sets of placement slots 3 that cooperate with the positioning slots 6. The design of the placement slots 3 makes it easier to limit the bottom position of the flat copper wires, improves the assembly uniformity of multiple sets of flat copper wires, avoids unevenness, and facilitates the rapid and uniform transfer of multiple sets of flat copper wires by the next robot.

[0029] The working principle of this utility model:

[0030] refer to Figures 1 to 4 The user inserts the plunger 10 into the placement block 7 and through the square hole 15 into the positioning groove 6. At this time, the user inserts both ends of the spring 12 into the corresponding fixing sleeve 11. The spring 12 provides a pulling force to the plunger 10 and a limiting force to prevent the plunger 10 from detaching from the placement block 7. Then, the user inserts the flat copper wire into the positioning groove 6. At this time, the chamfered part of the top of the plunger 10 will make contact with the flat copper wire in advance. The plunger 10 will move outward under force and stretch the spring 12. At the same time, the chamfered design avoids damage to the insulating varnish layer of the flat copper wire. Until the bottom end of the flat copper wire is inserted into the placement groove 3, the elastic rebound of the spring 12 provides a top fixing force to the flat copper wire, thereby quickly squeezing and positioning the flat copper wire. This effectively prevents the flat copper wire from shaking when inserted into the tooling and avoids positional movement. Then, the user can use the next robot to pick up and transfer multiple sets of flat copper wires as a whole.
