Description

Technical Field

[0001] This invention belongs to the field of stator coil manufacturing, and particularly relates to a stator coil transfer device. Background Technology

[0002] The stator coil is one of the core components of a generator set. It is installed on the stator core of a large generator set, and its performance directly affects the overall lifespan of the generator set, making its role crucial.

[0003] Each generator set has a large number of stator coils, and the stator coils of different sets have different sizes and specifications. Since the current production model involves the simultaneous production of stator coils for multiple generator sets, there is frequent transfer of stator coils of different sizes and specifications between production processes. Traditional stator coil production transfer involves multiple people using a tooling cart loaded with a certain number of stator coils, and then manually pushing the cart between production processes. This method is inefficient and labor-intensive. Furthermore, multiple coils pressed together in contact with the tooling cart can easily cause localized impacts and insulation damage to the stator coils. Therefore, the transfer of stator coils of different sizes and specifications is one of the urgent problems to be solved in the transfer between stator coil production processes.

[0004] To overcome the above situation, it is necessary to design a stator coil transfer device for different stator coil production and transfer modes, so as to realize the automatic transfer of stator coils of different sizes and specifications, while also taking into account the manual transfer mode, improve the transfer efficiency, and ensure the surface quality of the stator coils during the transfer process. The transfer device is easy to promote and has strong versatility. Summary of the Invention

Detailed Implementation

[0043] To make the objectives, technical solutions, and advantages of this invention clearer, the invention is described below with reference to specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0044] The connections mentioned in this invention are divided into fixed connections and detachable connections. Fixed connections, also known as non-detachable connections, include but are not limited to conventional fixed connection methods such as folded connections, riveted connections, adhesive connections, and welded connections. Detachable connections include but are not limited to conventional disassembly methods such as bolted connections, snap-fit ​​connections, pin connections, and hinged connections. When a specific connection method is not explicitly defined, it is assumed that at least one existing connection method can be found to achieve this function, and those skilled in the art can choose according to their needs. For example, a welded connection can be chosen for fixed connections, and a bolted connection can be chosen for detachable connections.

[0045] The present invention will be further described in detail below with reference to the accompanying drawings. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0046] Example: Figures 1 to 16 As shown, a stator coil transfer device includes:

[0047] A coil straight section support device is used to support and position the middle straight section of the stator coil;

[0048] An end horizontal positioning device is used to horizontally support and position the downward-sloping ends of the stator coils.

[0049] The end vertical positioning device is used to vertically support and position the upward-sloping ends of the stator coils;

[0050] The base 1 is equipped with universal wheels 2 at all four corners. The base 1 is used to install the coil straight section support device, the end horizontal positioning device and the end vertical positioning device, and can be manually pushed to transfer the fixed stator coil.

[0051] Automatically guided power vehicle 46 is used to automatically move to the car base 1 to realize the automatic transfer of stator coils on the back of the car base 1;

[0052] Two vertical positioning devices at the ends are symmetrically arranged at the left and right ends of the base 1. The coil straight section support device is located between the two vertical positioning devices at the ends. The two horizontal positioning devices at the ends are correspondingly arranged on the two coil straight section support devices.

[0053] The connection between the base 1 and the universal wheels 2 enables manual pushing of the stator coil for transport, and the automatic guide vehicle 46 can automatically move under the base 1 to automatically carry the base 1 for stator coil transport.

[0054] The coil straight section support device includes a middle support frame 4, a left adjusting bracket 5, and a right adjusting bracket 6. The left adjusting bracket 5 is slidably mounted on the left side of the vehicle base 1 via a first guide rail slider module 3, and the right adjusting bracket 6 is slidably mounted on the right side of the vehicle base 1 via the first guide rail slider module 3. A middle support frame 4 is provided between the left adjusting bracket 5 and the right adjusting bracket 6, and the middle support frame 4 is fixedly connected to the vehicle base 1. A first connecting frame 7 is fixedly connected to the right adjusting bracket 6, and the first connecting frame 7 is slidably connected to the middle support frame 4 via a second guide rail slider module 8. The first connecting frame 7 is provided with a left-right first rack 9, and the second connecting frame 12 is connected to the left adjusting bracket 5. The second connecting frame 12 is fixedly connected to the middle support frame 4 via the third guide rail slider module 13. The second connecting frame 12 is provided with a second rack 14 arranged left and right. The first servo motor drive module 11 is fixedly connected to the middle support frame 4. A first gear 10 is sleeved on the output shaft of the first servo motor drive module 11. The first gear 10 meshes with the first rack 9 and the second rack 14 respectively. The top of the left adjusting bracket 5 and the right adjusting bracket 6 are provided with support beams arranged front and back. The support beams of the left adjusting bracket 5 and the right adjusting bracket 6 are flush with the top of the middle support frame 4. The support beams of the left adjusting bracket 5 and the right adjusting bracket 6 are provided with several positioning hoops 15.

[0055] The first servo motor drive module 11 drives the first gear 10 to rotate, which in turn drives the first rack 9 and the second rack 14 to reciprocate linearly. This, in turn, drives the left adjusting bracket 5 and the right adjusting bracket 6 to move closer to or further away from each other. The distance between the left adjusting bracket 5 and the right adjusting bracket 6 is adjusted according to the length of the straight section in the middle of the stator coil, so that the middle straight section of the stator coil is supported by the three positions of the intermediate support frame 4, the left adjusting bracket 5, and the right adjusting bracket 6. The positioning clamp 15 is used for lateral positioning of the stator coil. The middle straight section of the stator coil extends between two adjacent positioning clamps 15, thus laterally positioning the middle straight section of the stator coil.

[0056] The positioning clamp 15 slides along the corresponding left adjusting bracket 5 or right adjusting bracket 6 and is locked in place by the locking pin 16.

[0057] Depending on the width of the stator coil, the distance between two adjacent positioning hoops 15 can be adjusted by sliding on the left adjusting bracket 5 and the right adjusting bracket 6. This allows for the adaptation and positioning of stator coils of different widths. The locking pin 16 passes through the hole in the positioning hoop 15, and rotating the locking pin 16 can quickly lock and fix the positioning hoop 15 after positioning.

[0058] The end horizontal positioning device includes two first square tubes 18, a first flexible support roller shaft 23, a first stepped shaft 26, and a second servo motor drive module 28.

[0059] When the end horizontal positioning device is set on the left adjustment bracket 5, the two first square tubes 18 are arranged in parallel front and rear, and are slidably connected to the left adjustment bracket 5 through the fourth guide rail slider module 17. The first square tube 18 is provided with a third rack 24, and the first stepped shaft 26 is arranged front and rear. The first stepped shaft 26 is rotatably set on the left adjustment bracket 5. The second servo motor drive module 28 is fixed on the left adjustment bracket 5. The output end of the second servo motor drive module 28 is connected to the first stepped shaft 26. Two second gears 25 are sleeved on the first stepped shaft 26. The two second gears 25 mesh with the two third racks 24 respectively. The left ends of the two first square tubes 18 are rotatably connected to the two ends of the first flexible support roller shaft 23 respectively.

[0060] The left adjusting bracket 5 and the right adjusting bracket 6 are symmetrical. The connection relationship between the left adjusting bracket 5 and the corresponding end horizontal positioning device is symmetrical to the connection relationship between the right adjusting bracket 6 and the corresponding end horizontal positioning device.

[0061] When this invention is used to support and transfer a C-type stator coil, the left end of the C-type stator coil is inclined downward to the left, and the right end is inclined downward to the right. When this invention is used to support and transfer an S-type stator coil, one end of the stator coil is inclined downward, and the other end is inclined upward. In these cases, the end horizontal positioning device is required to horizontally support and position the downwardly inclined end of the stator coil. The end horizontal positioning device is installed on the left adjusting bracket 5 and the right adjusting bracket 6 respectively. That is, both the left adjusting bracket 5 and the right adjusting bracket 6 have end horizontal positioning devices. The first flexible support roller shaft 23 of the end horizontal positioning device on the left adjusting bracket 5 and the right adjusting bracket 6 is located at the opposite end. The second servo motor drive module 28 drives the second gear 25 to rotate, which can drive the first flexible support roller shaft 23 on the left adjusting bracket 5 and / or the right adjusting bracket 6 to move and extend away, and can abut against and support the inner side of the downwardly inclined end of the stator coil. When used in conjunction with the coil straight section support device, the positioning and support of the stator coil can be achieved.

[0062] The first stepped shaft 26 is rotatably mounted on the left adjusting bracket 5 via two first bearing seats 27.

[0063] The end horizontal positioning device further includes a second square tube 19, a third gear 21, and a pawl device 22. When the end horizontal positioning device is set on the left adjustment bracket 5, the two second square tubes 19 are inserted and slidably set on the left side of the two first square tubes 18 in a one-to-one correspondence. The second square tube 19 is provided with a fourth rack 20, and the first square tube 18 is rotatably provided with a third gear 21. The two third gears 21 mesh with the two fourth racks 20 respectively. The pawl device 22 includes a frame and a pawl body. The frame rotates coaxially with the third gear 21. The pawl body is set on the frame and engages with any tooth groove of the third gear 21. The two ends of the first flexible support roller shaft 23 are rotatably connected to the left ends of the two second square tubes 19 respectively.

[0064] The end horizontal positioning device can achieve both manual and automatic operation control, whereby the second servo motor drive module 28 drives the second gear 25 to drive the third rack 24 to reciprocate linearly, thereby enabling the first square tube 18 to drive the first flexible support roller shaft 23 to move left and right together. Alternatively, it can be manually operated by using the pawl device 22 to drive the third gear 21 to rotate, causing the fourth rack 20 and the second square tube 19 to slide linearly back and forth along the inner hole of the first square tube 18, thereby enabling the second square tube 19 to drive the first flexible support roller shaft 23 to move left and right together. This invention achieves both manual and automatic operation control, and uses the first flexible support roller shaft 23 to provide horizontal support and positioning for the downwardly inclined end of the stator coil.

[0065] The end horizontal positioning device is symmetrical front and back, and the mid-plane of the second servo motor drive module 28 coincides with the front and rear mid-plane of the end horizontal positioning device.

[0066] By setting a second servo motor drive module 28 on the front and rear split surfaces, the second servo motor drive module 28 can apply force evenly to the movement of the two first square tubes 18.

[0067] The end vertical positioning device includes a transmission screw 32, a base platform 35, a synchronous lifting mechanism 37, a sleeve 39, a second flexible support roller shaft 41, and a second stepped shaft 43. The transmission screw 32 is arranged left and right and is rotatably mounted on the vehicle base 1. A third servo motor drive module 29 is connected to the vehicle base 1, and the output shaft of the third servo motor drive module 29 is connected to the transmission screw 32. A first nut 34 is provided on the transmission screw 32. The base platform 35 slides left and right on the vehicle base 1 through a fifth guide rail slider module 36 and is connected to the first nut 34. The second stepped shaft 43 is arranged front and rear. The second stepped shaft 43 is rotatably mounted on the base platform 35. Synchronous lifting machines 37 are respectively provided at the front and rear ends of the base platform 35. The fourth servo motor drive module 42 is provided in the middle of the base platform 35. The output end of the fourth servo motor drive module 42 is connected to the second stepped shaft 43. The two ends of the second stepped shaft 43 are respectively connected to the input shafts of the two synchronous lifting machines 37. The output screw of the synchronous lifting machine 37 is engaged with the second nut 38. The lower ends of the two sleeves 39 are respectively connected to the two second nuts 38. The upper ends of the two sleeves are respectively connected to the two ends of the second flexible support roller shaft 41 through the clamp 40.

[0068] The third servo motor drive module 29 drives the transmission screw 32 to drive the first nut 34 to perform horizontal reciprocating linear motion. This causes the entire device consisting of the base platform 35, synchronous lift 37, and second flexible support roller shaft 41 to perform horizontal reciprocating linear motion together with the first nut 34. This allows the end vertical positioning device to be adjusted horizontally to be below the support point of the upwardly inclined end of the S-shaped stator coil. The fourth servo motor drive module 42 drives the second stepped shaft 43 to rotate the synchronous lift 37 together. This causes the second nut 38 to perform up-and-down reciprocating linear motion. This, in turn, causes the entire device consisting of the sleeve 39, clamp 40, and second flexible support roller shaft 41 to perform vertical reciprocating motion together with the second nut 38. This allows the second flexible support roller shaft 41 to move vertically and support the lower side of the inclined surface of the upwardly inclined end of the S-shaped stator coil, thereby achieving the support and positioning of the upwardly inclined end of the S-shaped stator coil.

[0069] The fifth guide rail slider module 36, synchronous lift 37, second nut 38, sleeve 39, clamp 40, fourth bearing seat 44, and second coupling 45 in the end vertical positioning device are symmetrical devices relative to the fourth servo motor drive module 42. That is, with the position of the fourth servo motor drive module 42 as the center, the same devices are symmetrically located on both sides of the fourth servo motor drive module 42. The second bearing seat 44, synchronous lift 37, and second coupling 45 of the symmetrical device are connected to both ends of the second stepped shaft 43, and the clamp 40 of the symmetrical device is connected to both ends of the second flexible support roller shaft 41. This enables the fourth servo motor drive module 42 to drive the second stepped shaft 43 to drive the synchronous lift 37 of the symmetrical devices on both sides of the fourth servo motor drive module 42 to rise and fall synchronously. When the synchronous lift 37 of the symmetrical devices on both sides of the fourth servo motor drive module 42 rises and falls, the second nut 38, sleeve 39, clamp 40, and second flexible support roller shaft 41 rise and fall together.

[0070] By controlling the first servo motor drive module 11 of the coil straight section support device, auxiliary support and positioning of the middle straight section of S-shaped stator coils and C-shaped stator coils of different lengths can be automatically completed. By controlling the second servo motor drive module 28 of the end horizontal positioning device, the support and positioning of the downward tilted ends on both sides of the C-shaped stator coil can be automatically completed, as well as the auxiliary support and positioning of the downward tilted end of the S-shaped stator coil can be achieved. By controlling the third servo motor drive module 29 and the fourth servo motor drive module 42 of the end vertical positioning device, the auxiliary support and positioning of the upward tilted end of the S-shaped stator coil can be automatically completed.

[0071] The transmission screw 32 is rotatably mounted on the base 1 via the second bearing seat 31 and the third bearing seat 33, and the second stepped shaft 43 is rotatably mounted on the base platform 35 via the fourth bearing seat 44.

[0072] The output shaft of the third servo motor drive module 29 is connected to the transmission screw 32 via the first coupling 30, and the two ends of the second stepped shaft 43 are respectively connected to the input shafts of the two synchronous lifts 37 via the second coupling 45.

[0073] Compared to the current manual method, this invention enables the automatic transfer of stator coils of different sizes and specifications, while also incorporating manual transfer capabilities. It improves transfer efficiency, ensures the surface quality of the stator coils during transfer, and allows for the transport of a larger number of stator coils. The device is easy to implement and highly versatile. This invention solves the problems of traditional manual transfer using tooling carts, which suffers from limited capacity, unstable transfer process, low efficiency, and susceptibility to insulation damage caused by localized impacts to the stator coils.

[0074] The above embodiments are merely illustrative examples of the present invention and do not limit its scope of protection. Those skilled in the art can make partial changes to them, as long as they do not exceed the spirit and essence of the present invention, they are all within the scope of protection of the present invention.
