Description

Technical Field

[0001] This invention relates to the field of coil processing equipment, and in particular to a multi-unit synchronous rotating structure for stators. Background Technology

[0002] In the processing of coils, such as winding or welding (typically stator welding plates or windings), the current practice is to directly flip them by a rotating device in order to achieve a predetermined angle of rotation.

[0003] However, with the setup of multi-unit structures, that is, processing multiple products simultaneously, in order to achieve the consistency of flipping multiple products and thus ensure subsequent processing, the current practice is generally to use multiple sets of rotating devices, which are driven by servo rotating motors respectively, thereby realizing the simultaneous processing of multiple products.

[0004] However, multiple drive units also have the following problems:

[0005] 1. The cost of multiple drive units increases accordingly. In addition, the consistency adjustment and trial operation of multiple drive units in subsequent production are more troublesome, resulting in higher procurement and time costs.

[0006] 2. In order to ensure the same angle for the same coil, there is an adjustment gap for coils that have not been rotated to the predetermined position. Therefore, when the processing mechanism processes them simultaneously, there is a time lag, which affects production efficiency. Summary of the Invention

[0007] The main objective of this invention is to propose a multi-coil synchronous rotation structure for stators, which aims to achieve simultaneous rotation of multiple coils through a single drive device. The structure is simple and stable, while effectively reducing production costs.

[0008] To achieve the above objectives, the present invention proposes a multi-stage synchronous rotation structure for a stator, comprising:

[0009] A frame, wherein the frame is provided with spaced positioning plates and base plates;

[0010] A rotating shaft is pivotally mounted on a positioning plate, and multiple rotating shafts are provided and spaced apart.

[0011] A clamping cylinder is pivotally mounted between a positioning plate and a base plate. A hollow channel is provided in the middle of the rotating shaft. A pipe connected to the clamping cylinder is provided in the hollow channel. The front end of the pipe is connected to the clamping cylinder, and the rear end is connected to a hose or a rotary joint.

[0012] The clamping cylinder is fixedly connected to the rotating shaft;

[0013] A drive device, comprising a synchronous pulley pivotally mounted on the rear end of a rotating shaft and a drive belt connected to multiple synchronous pulleys, the drive belt being connected to a rotating device and used to drive multiple synchronous pulleys to rotate simultaneously;

[0014] Each rotating shaft has a calibration seat fixedly installed at its rear end, and the frame is provided with positioning points that mate with the calibration seat.

[0015] The rotating shaft is fixedly mounted with at least one elastic drive structure, one end of which is connected to a synchronous pulley, and the other end is connected to the rotating shaft.

[0016] When the drive belt drives the synchronous pulley to rotate, the synchronous pulley applies a rotational force to the elastic drive mechanism, and the elastic drive mechanism stores a predetermined torque to drive the rotating shaft to rotate.

[0017] When the synchronizing pulley rotates to a predetermined angle and stops, the torque stored in the elastic drive structure is released and continues to drive the correction seat to rotate, thereby causing multiple rotating shafts to rotate synchronously by a predetermined amplitude.

[0018] In practical design, when the drive belt drives multiple shafts simultaneously (i.e., multi-shaft structure), the shafts rotate at the same time. However, due to errors, some shafts may not rotate to the correct position (i.e., the alignment seat does not abut against the end of the positioning point). Therefore, by setting an elastic drive structure on the shaft, the first torsion spring is compressed by the synchronous pulley to achieve the rotation of the shaft and make the alignment seat abut against the first positioning post. However, due to errors, some shafts may not abut against the first positioning post. Therefore, the compression of the first torsion spring of the alignment seat that does not contact the first positioning post is released (the synchronous pulley is fixed, so the spring force of the first torsion spring tends towards the alignment seat), thus applying torque to the alignment seat and causing the shaft to rotate. This achieves synchronous movement of the multi-shaft structure with better synchronization and a simple and stable structure.

[0019] The hollow channel design also prevents messy wiring in the machinery. This hollow channel can also be used to house the wiring for the clamping electric cylinder, further preventing wiring clutter.

[0020] Of course, cylinders are cheaper and consume less energy, and at the same time, the installation of hoses does not affect the gas input. Attached Figure Description

[0040] like Figures 1 to 7 As shown, a multi-stage synchronous rotation structure for a stator includes:

[0041] A frame, wherein the frame is provided with spaced positioning plates and base plates;

[0042] A rotating shaft is pivotally mounted on a positioning plate, and multiple rotating shafts are provided and spaced apart.

[0043] A clamping cylinder is pivotally mounted between a positioning plate and a base plate. A hollow channel is provided in the middle of the rotating shaft. A pipe connected to the clamping cylinder is provided in the hollow channel. The front end of the pipe is connected to the clamping cylinder, and the rear end is connected to a hose or a rotary joint.

[0044] The clamping cylinder is fixedly connected to the rotating shaft;

[0045] A drive device, comprising a synchronous pulley pivotally mounted on the rear end of a rotating shaft and a drive belt connected to multiple synchronous pulleys, the drive belt being connected to a rotating device and used to drive multiple synchronous pulleys to rotate simultaneously;

[0046] Each rotating shaft has a calibration seat fixedly installed at its rear end, and the frame is provided with positioning points that mate with the calibration seat.

[0047] The rotating shaft is fixedly mounted with at least one elastic drive structure, one end of which is connected to a synchronous pulley, and the other end is connected to the rotating shaft.

[0048] When the drive belt drives the synchronous pulley to rotate, the synchronous pulley applies a rotational force to the elastic drive mechanism, and the elastic drive mechanism stores a predetermined torque to drive the rotating shaft to rotate.

[0049] When the synchronizing pulley rotates to a predetermined angle and stops, the torque stored in the elastic drive structure is released and continues to drive the correction seat to rotate, thereby causing multiple rotating shafts to rotate synchronously by a predetermined amplitude.

[0050] In practical design, when the drive belt drives multiple shafts simultaneously (i.e., multi-shaft structure), the shafts rotate at the same time. However, due to errors, some shafts may not rotate to the correct position (i.e., the alignment seat does not abut against the end of the positioning point). Therefore, by setting an elastic drive structure on the shaft, the first torsion spring is compressed by the synchronous pulley to achieve the rotation of the shaft and make the alignment seat abut against the first positioning post. However, due to errors, some shafts may not abut against the first positioning post. Therefore, the compression of the first torsion spring of the alignment seat that does not contact the first positioning post is released (the synchronous pulley is fixed, so the spring force of the first torsion spring tends towards the alignment seat), thus applying torque to the alignment seat and causing the shaft to rotate. This achieves synchronous movement of the multi-shaft structure with better synchronization and a simple and stable structure.

[0051] The hollow channel design also prevents messy wiring in the machinery. This hollow channel can also be used to house the wiring for the clamping electric cylinder, further preventing wiring clutter.

[0052] Of course, cylinders are cheaper and consume less energy, and at the same time, the installation of hoses does not affect the gas input.

[0053] In practice, the synchronous pulley does not drive the shaft to rotate, but drives the torsion spring, which in turn drives the shaft to rotate. When the torsion spring reaches the compression position, it drives the shaft to rotate. When the synchronous pulley stops, it can be understood as a fixed structure. Therefore, the spring force of the torsion spring is released, forcing the correction seat or linkage shaft to rotate.

[0054] Meanwhile, the hollow channel 20 also avoids the problem of messy machine wiring. Of course, the hollow channel 20 can also be used to place the wiring of the clamping electric cylinder, thus avoiding messy wiring.

[0055] Of course, cylinders are cheaper and consume less energy, and at the same time, the installation of hoses does not affect the gas input.

[0056] Specifically, the front wall of the clamping cylinder 3 is provided with two sets of clamping guide rails 31, and the clamping guide rails 31 are provided with clamping sliders 32. The clamping cylinder 3 is used to drive the clamping sliders 32 to slide along their length direction.

[0057] The two clamping sliders 32 are respectively provided with clamping arms 33, and the clamping arms 33 are provided with jaws 34. The relative movement of the jaws 34 is achieved by the clamping cylinder 3, thereby realizing the stable clamping of the stator.

[0058] In this embodiment of the invention, the clamping cylinder 3 is used to drive the two sliders to slide in a direction away from each other.

[0059] A tension spring 36 is provided between the rear ends of the two clamping arms 33. The tension spring 36 has two sets located on the upper and lower sides of the clamping arms 33, respectively. The tension spring 36 is used to apply a close tension force to the two clamping arms 33.

[0060] Specifically, by applying a similar tension force to the clamping arm 33 via the tension spring 36, the clamping force is more linear when clamping the stator, reducing clamping damage to the stator and allowing it to accommodate stators within a predetermined size range.

[0061] Of course, if the size difference is significant, replacement is necessary.

[0062] Meanwhile, the addition of double tension springs (36) also effectively ensures [the desired performance].

[0063] Specifically, the front end of the clamping arm 33 is provided with a bent wall 35, and the jaw 34 is provided with a mating wall that cooperates with the bent wall 35. The bent wall 35 of the rack structure can also effectively improve the installation stability between the clamping wall and the jaw 34, thereby maintaining clamping stability.

[0064] In this embodiment of the invention, the substrate 12 is provided with a vertical telescopic cylinder 62, the driving end of the vertical telescopic cylinder 62 is provided with a horizontal rod 61, the horizontal rod 61 is provided with a pressure seat 6, the pressure seat 6 is located above the clamping area of ​​the two grippers 34, the upper part of the pressure seat 6 is slidably mounted on the horizontal rod 61, and the horizontal rod 61 is sleeved with a top spring 63, the top spring 63 is used to apply downward pressure to the pressure seat 6, thereby realizing the clamping of the upper end of the stator, while ensuring elastic resistance and reducing scratches on the stator.

[0065] Specifically, when the positioning point is the first positioning post,

[0066] The elastic drive structure includes a first torsion spring, which is sleeved between the calibration seat and the rotating shaft. The calibration seat has a non-circular first positioning hole in the middle, and the rotating shaft is locked in the first positioning hole.

[0067] The calibration seat has a first notch on its side wall near the synchronous pulley. The first torsion spring is disposed within the first notch, with one end connected to the calibration seat and the other end connected to the side wall of the synchronous pulley.

[0068] When the synchronous pulley rotates, the synchronous pulley applies a torsional force to one end of the first torsion spring, causing the first torsion spring to drive the correction seat to rotate.

[0069] When the synchronizing pulley stops, the spring force of the first torsion spring is released, causing the calibration seat to rotate toward the first positioning post.

[0070] When the positioning point is the second positioning post.

[0071] The positioning plate is provided with a linkage shaft, which is sleeved on the positioning plate. The linkage shaft also has a second notch for accommodating a second torsion spring.

[0072] The second torsion spring is disposed within the second notch, with one end connected to the linkage shaft and the other end connected to the synchronous pulley.

[0073] When the synchronous wheel rotates toward the second positioning post, the synchronous wheel applies a torsional force to one end of the second torsion spring and causes the second torsion spring to drive the linkage shaft to rotate.

[0074] When the synchronizing pulley stops, the elastic force of the second torsion spring is released, causing the linkage shaft to rotate toward the second positioning post.

[0075] The principle is similar to that of the first torsion spring 51.

[0076] Specifically, the first torsion spring and the second torsion spring can have torque in the direction of the first positioning post and the second positioning post, respectively, so that when the synchronous pulley stops, the released torque can be a predetermined torque;

[0077] Alternatively, the first and second torsion springs can be pressurized and stored through a synchronous pulley. When the synchronous pulley stops, the released force can be the elastic force of the cover part.

[0078] Of course, both pre-stored torque and compressed stored torque can coexist, and the design can be tailored to actual needs.

[0079] Meanwhile, the double torsion spring structure can also ensure the stability of the elastic force and can achieve position correction in the first and second directions (i.e., clockwise and counterclockwise).

[0080] The arrangement of the first torsion spring 51 and the second torsion spring 71 allows for the accumulation of greater elastic force, and the release of elastic force is more linear.

[0081] In this embodiment of the invention, the linkage shaft 7 is provided with a second positioning hole 72, which is composed of a round hole and a strip hole. The rotating shaft 2 is provided with a stepped portion 72a that cooperates with the second positioning hole 72, thereby ensuring the stable installation between the linkage shaft 7 and the rotating shaft 2.

[0082] Specifically, the front end of the rotating shaft 2 is provided with a coupling 8, the coupling 8 is provided with a clamping groove 81, the inner end wall of the clamping groove 81 is provided with a sealing ring 82, the clamping cylinder 3 is provided in the clamping groove 81, the rear end wall of the clamping cylinder 3 abuts against the sealing ring 82, and the clamping groove 81 is connected to the hollow channel 20, which not only ensures the stable installation of the clamping cylinder 3, but also ensures the gas delivery and the stability of the installation.

[0083] In this embodiment of the invention, a guide wheel 43 is provided between the drive belt 42 and each synchronous pulley 41, thereby ensuring the tension of the drive belt 42.

[0084] Specifically, bearings are provided at the positions of the positioning plate 11 and the base plate 12 to ensure smooth and accurate rotation.

[0085] The correction seat extends radially with a stop 5a that is larger than the diameter of the rotating shaft.

[0086] The synchronous pulley is mounted on rotating bearings on both sides. The front and rear walls of the rotating bearings are provided with limiting grooves 100, which are used to install the first end of the first torsion spring and the second end of the second torsion spring, respectively.

[0087] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
