Description

Technical Field

[0001] The invention relates to the field of stator winding processing, in particular to a stator winding transfer device. Background Art

[0002] Stator winding refers to the winding installed on the stator, that is, the copper wire wound on the stator. Winding is a general term for a phase or the entire electromagnetic circuit composed of multiple coils or coil groups.

[0003] Stator winding is widely completed using copper wire winding machines, and the tool used to load and transfer the stator windings is typically called a winding die. However, existing winding dies have a single structure and function, loading and transferring only one set of copper wire windings at a time. This requires frequent assembly and disassembly, hindering process efficiency. Therefore, a stator winding transfer device was proposed to address this issue. Summary of the Invention

[0004] The object of the present invention is to provide a stator winding transfer device in order to solve the above problems.

[0005] The present invention achieves the above-mentioned object through the following technical scheme: a stator winding transfer device, comprising a long gear-insertion workpiece, a winding separation assembly, a pullback assembly and a hollow shaft servo motor, wherein the threaded end portion located at the rear end of the long gear-insertion workpiece is threadedly connected to the inner portion of the hollow shaft port of the hollow shaft servo motor, and the long gear-insertion workpiece is located in the middle of the winding separation assembly area, the hollow circular block located in the pullback assembly extends into the interior of the long gear-insertion workpiece through a second cylinder, and each guide rod located on the annular surface of the hollow circular block extends through the gap located on the long gear-insertion workpiece, and multiple groups of semi-annular partitions located in the winding separation assembly form multiple sections of separation spaces for the long gear-insertion workpiece, and the four semi-annular partitions in each group clamp and separate a group of copper wire windings located on the long gear-insertion workpiece.

[0006] Preferably, the winding separation assembly also includes a first magnetic component, a square slot socket, a second magnetic component and a first cylinder. The square slot socket is fixedly installed in the middle of the outer edge of the semi-ring partition, and the inside of the square slot socket is inserted into the square plug located at the output end of the first cylinder. The first magnetic component is installed on one side surface of the semi-ring partition, and the two second magnetic components of the same group are respectively installed on the end faces of the same semi-ring partition.

[0007] Preferably, the first cylinders are provided in two groups, and the two groups of first cylinders are respectively installed inside the two side frames, and the bottoms of the two side frames are fixedly installed on the front end of the top surface of the machine plate.

[0008] Preferably, the pullback assembly also includes a channel, a spring and a pneumatic control device, and multiple channels are distributed in an annular shape on the annular surface of the hollow circular block, and the middle part of one side of the hollow circular block is interconnected with the output end of the second cylinder. The inside of each channel is slidingly and sealedly connected to one end of the guide rod through a piston ring, and a spring is installed on the end face of one end of the guide rod located inside the channel, and one end of the spring is interconnected with the corresponding position located inside the hollow circular block.

[0009] Preferably, the pneumatic control device is communicated with the interior of the hollow circular block through an air duct, and the pneumatic control device is installed on the rear end side of the top of the machine plate.

[0010] Preferably, the long-slotted workpiece is composed of a plurality of long-slotted teeth distributed in a ring shape, and the threaded end portion located at the rear end of the long-slotted workpiece is a tubular structure.

[0011] Preferably, the cylinder body of the second cylinder is fixedly connected to the machine plate via a connecting plate.

[0012] Preferably, the bottom of the hollow shaft servo motor is slidably mounted on two guide rails, and the two guide rails are symmetrically mounted in the middle of the machine plate.

[0013] Preferably, a third cylinder is installed at the bottom of the back side of the hollow shaft servo motor, and the cylinder body of the third cylinder is connected to the machine plate.

[0014] The beneficial effects of the present invention are: At least three groups of copper wire windings on a long slotted gear workpiece are separated in an orderly manner by at least three groups of semi-ring partitions, replacing the method in which a single long slotted gear workpiece can only carry one group of copper wire windings. This solves the problem of confusion when a single long slotted gear workpiece is loaded with multiple groups of copper wire windings, reduces the replacement frequency of the long slotted gear workpiece at the winding machine, and improves the stator winding processing efficiency.

[0015] Through the first magnetic attraction member and the second magnetic attraction member on each set of semi-annular separators, two complete annular separators can be magnetically connected to form each other, and the copper wire windings can be magnetically clamped and bound to prevent the copper wire windings from becoming loose.

[0016] By plugging the square plug at the output end of the first cylinder into the square slot socket on the semi-ring partition, the square plug can be removed from the square slot socket by the contracting first cylinder under the action of the magnetic binding force of the semi-ring partition, thereby achieving convenient disconnection from the semi-ring partition and preventing obstruction to the movement and separation of the next group of copper wire windings.

[0023] See also Figure 1-6 As shown, a stator winding transfer device includes a long gear-slotting workpiece 1, a winding separation assembly, a pullback assembly and a hollow shaft servo motor 4. The threaded end 110 located at the rear end of the long gear-slotting workpiece 1 is threadedly connected to the inner surface of the hollow shaft port of the hollow shaft servo motor 4, and the long gear-slotting workpiece 1 is located in the middle of the winding separation assembly area. The hollow circular block 12 located in the pullback assembly extends into the interior of the long gear-slotting workpiece 1 through a second cylinder 5, and each guide rod 13 located on the annular surface of the hollow circular block 12 extends through the gap located on the long gear-slotting workpiece 1. Multiple groups of semi-annular partitions 2 located in the winding separation assembly form multiple separation spaces for the long gear-slotting workpiece 1. The four semi-annular partitions 2 in each group clamp and separate a group of copper wire windings located on the long gear-slotting workpiece 1.

[0024] Furthermore, the winding separation assembly also includes a first magnetic component 210, a square slot socket 220, a second magnetic component 230 and a first cylinder 3. The square slot socket 220 is fixedly installed in the middle of the outer edge of the semi-ring partition 2, and the interior of the square slot socket 220 is inserted into the square plug 310 located at the output end of the first cylinder 3. The first magnetic component 210 is installed on one side surface of the semi-ring partition 2, and the two second magnetic components 230 of the same group are respectively installed on the end faces of both ends of the same semi-ring partition 2. The first cylinder 3 is provided with two groups, and the two groups of first cylinders 3 are respectively installed inside the two side frames 7, and the bottoms of the two side frames 7 are fixedly installed on the front end of the top surface of the machine plate 11.

[0025] Furthermore, the pullback assembly also includes a channel 12a, a spring 14 and a pneumatic control device 6. Multiple channels 12a are distributed in a ring on the annular surface of the hollow round block 12, and the middle part of one side of the hollow round block 12 is interconnected with the output end of the second cylinder 5. The interior of each channel 12a is slidingly and sealedly connected to one end of the guide rod 13 through a piston ring, and a spring 14 is installed on the end face of one end of the guide rod 13 located inside the channel 12a, and one end of the spring 14 is interconnected with the corresponding position located inside the hollow round block 12. The pneumatic control device 6 is connected to the interior of the hollow round block 12 through an air guide pipe, and the pneumatic control device 6 is installed on the rear end side of the top of the machine plate 11.

[0026] Furthermore, the long-slotted gear workpiece 1 is composed of a plurality of long-slotted gears distributed in a ring shape, and the threaded end portion 110 located at the rear end of the long-slotted gear workpiece 1 is a tubular structure.

[0027] The cylinder body of the second cylinder 5 is fixedly connected to the machine plate 11 through the connecting plate 8. When the second cylinder 5 is operated, the position of the connected hollow circular block 12 can be adjusted to complete the pulling back and compacting of the copper wire winding to be processed.

[0028] The bottom of the hollow shaft servo motor 4 is slidably mounted on two guide rails 9, and the two guide rails 9 are symmetrically mounted in the middle of the machine plate 11. A third cylinder 10 is installed at the bottom of the back of the hollow shaft servo motor 4, and the cylinder body of the third cylinder 10 is connected to the machine plate 11. The position of the hollow shaft servo motor 4 and the long gear shaping workpiece 1 connected thereto can be adjusted by extending and retracting the third cylinder 10.

[0029] The specific operation process steps are as follows: Step 1: The hollow shaft servo motor 4 drives the connected long gear shaping workpiece 1 to rotate multiple times at different angles, so that the winding machine winds a group of copper wires around the front end of the long gear shaping workpiece 1; Step 2: After the copper wires are wound around the long gear-shaping workpiece 1, the second cylinder 5 is extended to move the connected hollow block 12 to the location where the copper wires are wound. The hollow block 12 is inflated via the pneumatic control device 6, causing the guide rod 13 located inside the channel 12a to extend, forcing the outer end of the guide rod 13 to pass through the gap on the long gear-shaping workpiece 1, so that the guide rod 13 partially contacts the intersection between the copper wires and the long gear-shaping workpiece 1. The second cylinder 5 is then operated again, switching from extension to contraction, so that the copper wire windings at that location are pulled inward. Step 3: When the copper wire windings of one group are moved to the set position on the long gear-shaping workpiece 1, the four first cylinders 3 in one group extend and push the semi-annular separators 2 connected to them to move to the empty positions on the long gear-shaping workpiece 1 on both sides of the copper wire windings. The two opposing semi-annular separators 2 are magnetically connected together by the second magnetic members 230 at their ends to form a complete annular separator. Step 4: Under the action of the magnetic connection of the second magnetic member 230, the first cylinder 3 contracts and resets, so that the square plug 310 at its end is separated from the square slot socket 220 located on the semi-annular partition 2. At this time, the two complete annular partitions formed in front and behind the copper wire winding at this location are magnetically connected together by the first magnetic member 210, so that one set of semi-annular partitions 2 is magnetically firmly bound to the copper wire winding at this location, thereby preventing the copper wire winding group from loosening and mixing with other copper wire winding groups; Step 5: Separate the remaining copper wire windings one by one according to the above steps. When the copper wire windings are separated on the long gear-shaping workpiece 1, the staff removes the long gear-shaping workpiece 1 from the hollow shaft servo motor 4 and moves it to the stator press-fit copper wire winding station.

[0030] Compared with the existing technology, the differences are: First, at least three groups of copper wire windings on a long gear-shaping workpiece 1 are separated in an orderly manner by at least three groups of semi-ring partitions 2. This replaces the method of loading only one group of copper wire windings on a single long gear-shaping workpiece 1. This solves the problem of a single long gear-shaping workpiece 1 being loaded with multiple groups of copper wire windings in a disorderly manner, reduces the replacement frequency of the long gear-shaping workpiece 1 at the winding machine, and improves the stator winding processing efficiency.

[0031] Second, the first magnetic member 210 and the second magnetic member 230 on each set of semi-annular separators 2 can be magnetically connected to form two complete annular separators, and can also magnetically clamp and restrain the copper wire windings to prevent the copper wire windings from loosening.

[0032] 3. By inserting the square plug 310 at the output end of the first cylinder 3 into the square slot socket 220 on the semi-annular partition 2, it is convenient to remove the square plug 310 from the square slot socket 220 through the contraction of the first cylinder 3 under the action of the magnetic binding force of the semi-annular partition 2, thereby achieving convenient disconnection from the semi-annular partition 2 and preventing obstruction to the movement and separation of the next group of copper wire windings.
