Description

Technical Field

[0001] This invention relates to the field of mechanical transmission technology, and in particular to an intermittent oscillation mechanism for motor winding. Background Technology

[0002] Intermittent oscillating mechanisms have wide applications in automation. These devices enable intermittent oscillating output from the output shaft or output disc, and are used in various automated machinery, robotic arms, and automated production lines where actuators need to achieve oscillating motions of a certain stroke. Examples include conveying parts, winding coils, painting, stamping, and automatic feeding. In the winding process of motor coils, an intermittent oscillating device is typically installed between the drive unit and the winding rod, allowing the winding rod to oscillate intermittently for coil winding. For instance, Chinese invention patent CN113489259B discloses a stable and efficient stator winding machine, comprising: a support member; a vertical drive member, including a vertical power member, a vertical fixing member, and a vertical moving member; a radial transmission rod mounted on the vertical moving block; a first transmission wheel mounted on the radial transmission rod; a first transmission belt mounted on the first transmission wheel; and a radial motor mounted on the support plate; and a reciprocating oscillating member, including an oscillating transmission member, an oscillating power member, and a winding head.

[0003] However, for coils of different specifications, the swing amplitude of the winding rod needs to be adjusted. Most swing mechanisms swing at a fixed angle. When different specifications of coils need to be wound, the machine needs to be stopped and the swing device replaced, which is inconvenient to operate and has poor applicability. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the aforementioned technologies by designing an intermittent oscillation mechanism for motor winding. This mechanism can flexibly adjust the oscillation amplitude of the oscillating component as needed, making it suitable for winding coils of different specifications. It not only improves work efficiency and reduces operational complexity, but also enhances the flexibility and applicability of the oscillation mechanism.

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is: an intermittent oscillation mechanism for motor winding, comprising: The mounting base has two symmetrically arranged support columns, and a support plate is provided between the upper ends of the two support columns. A swinging component is pivotally connected to the support plate. The upper end of the swinging component is a swing output end, and the lower end of the swinging component is provided with a swing rod. A joint bearing is sleeved on the swing rod, and an annular drive groove is opened on the outer wall of the joint bearing. Two swing drive assemblies are provided, each comprising a transmission rod and a transmission ring. The two transmission rods are symmetrically arranged around the swing element. The upper end of each transmission rod is rotatably connected to the support plate, and the lower end of each transmission rod is rotatably connected to the mounting base. The lower end of each transmission rod extends to the outer side of the bottom surface of the mounting base, and the lower ends of the two transmission rods are connected by a synchronous belt drive. The transmission ring is sleeved on the transmission rod and can slide up and down along the axial direction of the transmission rod. An eccentric cam is provided on the outer wall of the transmission ring. The two eccentric cams are arranged opposite each other, and the opposite sides of the two eccentric cams abut against the inner wall of the drive groove. The swing adjustment assembly includes an adjustment plate and an adjustment transmission structure for driving the adjustment plate to move up and down. The adjustment plate is provided with a connecting part for the transmission ring to rotate and connect.

[0006] Preferably, the outer wall of the transmission rod has at least one transmission plane extending along its axial direction, and the inner wall of the transmission ring abuts against the outer wall of the transmission rod.

[0007] Preferably, the adjustment transmission structure is a threaded lead screw, which is rotatably connected to the mounting base, and the adjustment plate is provided with a drive ring threadedly connected to the adjustment transmission structure.

[0008] Preferably, the lower end of the adjusting transmission structure extends to the outer side of the bottom surface of the mounting base, and the lower end of the adjusting transmission structure is provided with an adjusting input shaft.

[0009] Preferably, the swing adjustment assembly further includes at least one adjustment guide rod, the upper end of which is rotatably connected to the support plate, and the lower end of which is rotatably connected to the mounting base. An adjustment sleeve fitted onto the adjustment guide rod is provided on the adjustment plate.

[0010] Preferably, there are two adjusting guide rods, which are arranged symmetrically about the adjusting transmission structure.

[0011] Preferably, the support plate is provided with a swing groove for the swinging member to move through, and the inner walls of the two sides of the opening side of the swing groove are inclined relative to each other.

[0012] Preferably, the distance between the support plate and the mounting base is greater than the length of the swing rod.

[0013] Preferably, the connecting part is a C-shaped shift fork, and the upper part of the transmission ring has an annular connecting groove. The connecting part is inserted into the connecting groove, so that the transmission ring can rotate relative to the connecting part.

[0014] Preferably, the swing output end of the swing member is an arc-shaped swing tooth structure.

[0015] Compared with the prior art, the beneficial effects of the present invention are: When the adjusting plate is raised or lowered by adjusting the transmission structure, the adjusting plate can drive the two transmission rings to move up and down, thereby changing the height position of the joint bearing. When the joint bearing is close to the pivot position of the swinging component, the swing amplitude of the swinging component is larger, but more force needs to be applied; when the joint bearing is far away from the pivot position of the swinging component, the swing amplitude of the swinging component is smaller, but the operation is relatively less strenuous. This swinging mechanism can flexibly adjust the swing amplitude of the swinging component as needed, and is suitable for winding coils of different specifications. It not only improves work efficiency and reduces operational complexity, but also enhances the flexibility and applicability of the swinging mechanism. Attached Figure Description

[0018] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0019] refer to Figure 1 , Figure 2 , Figure 3 An intermittent oscillation mechanism for motor winding includes a mounting base 1, an oscillating element 2, two oscillation drive assemblies 3, and an oscillation adjustment assembly 4. The mounting base 1 is provided with two symmetrically arranged support columns 101, and a support plate 102 is provided between the upper ends of the two support columns 101. The oscillating element 2 has a Y-shaped structure and is pivotally connected to the support plate 102. The support plate 102 is provided with a oscillation groove 103 for the oscillating element 2 to move through it. The inner walls on both sides of the opening side of the oscillation groove 103 are inclined relative to each other and are V-shaped. The inner walls on both sides of the opening side of the oscillation groove 103 are used to limit the oscillation stroke of the oscillating element 2.

[0020] A swing rod 201 is provided at the lower end of the swing component 2. The swing rod 201 is the swing output end 204 of the swing component 2. A spherical bearing 202 is sleeved on the swing rod 201. An annular drive groove 203 is formed on the outer wall of the spherical bearing 202. The distance between the support plate 102 and the mounting base 1 is greater than the length of the swing rod 201, so that space is reserved between the support plate 102 and the mounting base 1 for the swing rod 201 to move.

[0021] The oscillating drive assembly 3 includes a transmission rod 31 and a transmission ring 32. The two transmission rods 31 are symmetrically arranged about the oscillating member 2. The upper end of each transmission rod 31 is rotatably connected to a support plate 102, and the lower end is rotatably connected to a mounting base 1. The lower end of each transmission rod 31 extends to the outer side of the bottom surface of the mounting base 1, and the lower ends of the two transmission rods 31 are driven by a synchronous belt 5. Preferably, a first synchronous pulley 304 is provided at the lower end of each transmission rod 31, and a second synchronous pulley 104 is rotatably connected to the bottom surface of the mounting base 1. A synchronous belt 5 is fitted between the two first synchronous pulleys 304 and the second synchronous pulley 104. Either of the two transmission rods 31 is connected to the output shaft of an external rotary motor, thereby driving the two transmission rods 31 to rotate synchronously.

[0022] refer to Figure 4 , Figure 5 , Figure 6 , Figure 7 The transmission rod 31 has a rectangular cross-section, and its outer wall has four transmission planes 301 extending along the axial direction of the transmission rod 31. A transmission ring 32 is fitted onto the transmission rod 31, with its inner wall engaging with the outer wall of the transmission rod 31, allowing the transmission ring 32 to slide up and down along the axial direction of the transmission rod 31. The transmission planes 301 allow the transmission ring 32 to rotate with the transmission rod 31.

[0023] An eccentric cam 302 is provided on the outer wall of the transmission ring 32. The eccentric cam 302 is inserted into the drive groove 203. The two eccentric cams 302 are arranged opposite each other, and the opposite sides of the two eccentric cams 302 abut against the inner wall of the drive groove 203. When the two transmission rods 31 drive the two transmission rings 32 to rotate synchronously, the two eccentric cams 302 rotate synchronously, and the linkage joint bearing 202 performs intermittent oscillating motion, thereby driving the oscillating member 2 to oscillate back and forth in the drive groove 203. The upper end of the oscillating member 2 is the oscillation output end 204. The oscillation output end 204 of the oscillating member 2 has an arc-shaped oscillating tooth structure, so that when the oscillating member 2 rotates, the oscillation output end 204 of the oscillating member 2 can drive the external linkage mechanism to achieve reciprocating oscillation motion by means of rack and pinion transmission. For example, the external linkage mechanism is a winding rod with a driving rack, and the driving rack meshes with the oscillation output end 204 of the oscillating member 2.

[0024] The swing adjustment assembly 4 includes an adjustment plate 41, an adjustment transmission structure 42, and two adjustment guide rods 43. The two adjustment guide rods 43 are symmetrically arranged around the adjustment transmission structure 42. The upper end of the adjustment guide rod 43 is rotatably connected to the support plate 102, and the lower end of the adjustment guide rod 43 is rotatably connected to the mounting base 1. The adjustment plate 41 is provided with an adjustment sleeve 403 sleeved on the adjustment guide rod 43, so that the adjustment plate 41 can move up and down along the axial direction of the adjustment guide rod 43. The adjustment transmission structure 42 is a threaded screw, which is rotatably connected to the mounting base 1. The adjustment plate 41 is provided with a drive ring 402 threadedly connected to the adjustment transmission structure 42, so that the adjustment transmission structure 42 is used to drive the adjustment plate 41 to move up and down. The adjusting plate 41 is provided with a connecting part 401 for the rotatable connection of the transmission ring 32. The connecting part 401 is a C-shaped fork. The upper part of the transmission ring 32 has an annular connecting groove 303. The connecting part 401 is inserted into the connecting groove 303, so that the transmission ring 32 can rotate relative to the connecting part 401. When the adjusting plate 41 moves up and down, the adjusting plate 41 drives the transmission ring 32 to move up and down along the axial direction of the transmission rod 31 on which it is sleeved, thereby adjusting the position of the joint bearing 202 relative to the swing rod 201.

[0025] Preferably, the lower end of the adjusting transmission structure 42 extends to the outer side of the bottom surface of the mounting base 1, and the lower end of the adjusting transmission structure 42 is provided with an adjusting input shaft 404. The adjusting input shaft 404 is equipped with a handle or a rotary motor, so that the adjusting transmission structure 42 can be driven to rotate by manual operation or motor drive. Then, the height position of the adjusting plate 41 can be adjusted by the threaded engagement between the driving ring 402 and the adjusting transmission structure 42.

[0026] refer to Figures 1 to 7When in use, the swing mechanism uses two eccentric cams 302 arranged opposite each other, with a phase difference of 180°. The two transmission rods 31 rotate synchronously through the synchronous belt 5, so that the two eccentric cams 302 rotate synchronously, in the same direction, and at the same angular velocity, keeping the distance between the two eccentric cams 302 constant. The opposite sides of the two eccentric cams 302 abut against the inner wall of the drive groove 203, so that the eccentric cams 302 limit the position of the joint bearing 202 relative to the swing rod 201. When the two eccentric cams 302 rotate synchronously, they can drive the joint bearing 202 to translate left and right with a constant stroke, thereby causing the joint bearing 202 to drive the swing member 2 to swing back and forth.

[0027] When the adjusting plate 41 is raised or lowered by adjusting the transmission structure 42, the adjusting plate 41 can drive the two transmission rings 32 to move up and down, thereby changing the height position of the joint bearing 202. When the joint bearing 202 is close to the pivot position of the swing member 2, the swing amplitude of the swing member 2 is larger, but more force needs to be applied; when the joint bearing 202 is far away from the pivot position of the swing member 2, the swing amplitude of the swing member 2 is smaller, but the operation is relatively less strenuous. This swing mechanism can flexibly adjust the swing amplitude of the swing member 2 as needed, and is suitable for winding coils of different specifications. It not only improves work efficiency, but also reduces the complexity of operation, and enhances the flexibility and applicability of the swing mechanism.

[0028] Of course, the above are just typical examples of the present invention. In addition, the present invention may have many other specific embodiments. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by the present invention.
