Description

Technical Field

[0001] This utility model relates to the field of wire stripping technology, and in particular to a two-position centrifugal stripping mechanism. Background Technology

[0002] When making coils with enameled wire, the surfaces of the two ends of the coil, i.e., the electrical terminals, need to be treated to remove the insulation layer and make them conductive. Therefore, the electrical terminals need to be stripped.

[0003] Existing wire stripping equipment separates the outer sheath of the wire from the whole by rotating the stripping blade at a selected position. Existing stripping equipment generally requires adjusting the stripping blade to align with the wire before rotating the stripping blade to strip the wire. Moreover, when replacing the wire after stripping, the stripping blade needs to be manually adjusted to align the wire with the stripping blade due to the lack of a reset mechanism, resulting in low wire stripping efficiency. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide a dual-position centrifugal stripping mechanism. This mechanism solves the problem that when replacing a new wire after stripping with the existing stripping equipment, the stripping blade needs to be manually adjusted to align the wire with the stripping blade due to the lack of a reset structure, resulting in low wire stripping efficiency.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a dual-position centrifugal peeling mechanism, comprising a body and a drive component mounted on the body, wherein the output shaft of the drive component is connected to two peeling components arranged at intervals via a transmission assembly.

[0006] Each stripping assembly includes a connecting rod connected to the output end of the transmission assembly, a blade holder mounted on the connecting rod, and three centrifugal stripping units rotatably mounted on the blade holder; the blade holder is provided with positioning holes for positioning the wire.

[0007] Each centrifugal peeling unit includes a blade rod rotatably mounted on a blade holder. One end of the blade rod near the positioning hole is equipped with a peeling blade, and the other end is equipped with a centrifugal block. A reset component is connected to the centrifugal block. When the machine is stopped, the reset component drives each centrifugal peeling unit to reset.

[0008] Furthermore, the reset assembly includes a sleeve fitted onto the connecting rod and a turntable, with a torsion spring connecting the sleeve and the turntable, and the centrifugal block connected to the turntable.

[0009] Furthermore, the centrifuge block is equipped with a transmission rod, one end of which is connected to the turntable, and the other end is connected to the centrifugal peeling unit.

[0010] Furthermore, the turntable has a slot on its side edge that is compatible with the transmission rod, through which the transmission rod passes.

[0011] Furthermore, the blade holder includes a first carrier plate located next to the centrifuge block and a second carrier plate located next to the peeling blade. The first and second carrier plates are arranged opposite to each other, and the blade bar passes through the first and second carrier plates.

[0012] Furthermore, the second carrier plate is provided with an opening corresponding to the three centrifugal peeling units, and the transmission rod extends into the opening. A movable limiting member is provided on any side edge of the second carrier plate, with one end of the limiting member extending into the adjacent opening and corresponding to the transmission rod inside the opening.

[0013] Furthermore, a space is provided between the two opposite walls of the opening for the displacement of the transmission rod.

[0014] Furthermore, a movable torsion rod is provided on one side of the centrifuge block, with one end of the torsion rod extending into the centrifuge block and abutting against the blade rod inside the centrifuge block.

[0015] Furthermore, the blade holders are inclined and close together, with the positioning hole located between the three blade holders, so that the three stripping blades can make equidistant contact with the wires inserted into the positioning hole.

[0016] Furthermore, the transmission assembly includes a drive rod connected to the machine body, one end of which is connected to the output shaft of the drive component via a meshing transmission component, and the other end of which is connected to a connecting rod.

[0017] This invention has significant advantages and beneficial effects compared with existing technologies. Specifically, as shown in the above technical solution, the driving component drives the transmission assembly, causing the connecting rod to rotate the blade holder and the blade bar on the blade holder. Simultaneously, the rotation of the connecting rod also causes the centrifugal block to move inertia, causing the blade bar to rotate and its stripping blade to clamp the wire. At the same time, the entire centrifugal stripping unit rotates with the connecting rod, causing the stripping blade to rotate and strip the wire. After stripping, the driving component stops operating. Without the inertial force of the centrifugal block, the reset assembly drives the centrifugal block to reset, and the blade bar resets along with the centrifugal block. This facilitates the insertion of new wires into the positioning hole, allowing the driving component to run again to facilitate the stripping blade stripping the wire, thereby improving the efficiency of wire stripping.

[0030] Please refer to Figure 1-5 As shown, it illustrates the specific structure of a preferred first embodiment of the present invention, which is a dual-position centrifugal peeling mechanism, including a body 10 and a drive member 20 disposed on the body 10. The output shaft of the drive member 20 is connected to two peeling components 40 arranged at intervals via a transmission assembly 30.

[0031] Each peeling assembly 40 includes a connecting rod 41 connected to the output end of the transmission assembly 30, a blade holder 42 disposed on the connecting rod 41, and three centrifugal peeling units 43 rotatably disposed on the blade holder 42; the blade holder 42 is provided with positioning holes 44 for positioning the wire.

[0032] Each centrifugal peeling unit 43 includes a blade 431 rotatably mounted on a blade holder 42. One end of the blade 431 near the positioning hole 44 is provided with a peeling blade 432, and the other end is provided with a centrifugal block 433. A reset component 50 is connected to the centrifugal block 433. When the machine is stopped, the reset component 50 drives each centrifugal peeling unit 43 to reset. Compared to existing dual-position centrifugal wire stripping mechanisms, which require the stripping blade to be adjusted and aligned with the wire before rotation for stripping, and the stripping blade needs to be manually adjusted and reset after stripping, this dual-position centrifugal wire stripping mechanism uses a drive unit 20 to drive the transmission assembly 30, causing the connecting rod 41 to rotate the blade holder 42 and the blade rod 431 on the blade holder 42. Simultaneously, the rotation of the connecting rod 41 causes the centrifugal block 433 to move inertia, causing the blade rod 431 to rotate and the stripping blade 42 to clamp the wire. The entire centrifugal wire stripping unit 40 rotates with the connecting rod 41, causing the stripping blade 42 to rotate and strip the wire. After stripping, the drive unit 20 stops, and the centrifugal block 433, lacking inertial force, is reset by the reset assembly 50, and the blade rod 431 resets along with the centrifugal block 433. This facilitates the insertion of new wires into the positioning hole 44, allowing the drive unit 20 to run again for the stripping blade 42 to strip the wire, thus improving the efficiency of wire stripping.

[0033] like Figure 3 As shown, exemplarily, the reset assembly 50 includes a sleeve 51 and a turntable 52 sleeved on the connecting rod 41. A torsion spring 53 is connected between the sleeve 51 and the turntable 52, and the centrifugal block 433 is connected to the turntable 52. When the connecting rod 41 rotates with the drive of the drive member 20, due to the connection between the centrifugal block 433 and the turntable 52, the centrifugal block 433 rotates around the cutter bar 431 under the centrifugal force brought about by the rotation of the connecting rod 41. The turntable 52 rotates with the centrifugal block 433. At this time, because one end of the torsion spring 53 is connected to the turntable 52, the torsion spring 53 undergoes elastic deformation. When the drive unit 20 stops running, the connecting rod 41 stops rotating due to the lack of a power source. At this time, the torsion spring 53, due to the lack of centrifugal force, drives the turntable 52 to reset. The turntable 52 then drives the centrifugal block 433 to reset. When the centrifugal block 433 resets, it drives the blade 431 to rotate and reset, thereby moving the stripping blade 432 on the blade 431 to the side of the positioning hole 44, so that the new wire to be stripped can be inserted into the positioning hole 44. When the drive unit 20 is driven again, the blade 431 moves with the centrifugal block 433 under centrifugal force, and the stripping blade 432 on the blade 431 contacts the wire.

[0034] like Figure 4As shown, for example, a transmission rod 54 is provided on the centrifugal block 433. One end of the transmission rod 54 is connected to the turntable 52, and the other end is connected to the centrifugal peeling unit 43. To facilitate the inertial movement of the centrifugal block 433 driven by centrifugal force, a transmission rod 54 extending outward at both ends is installed on the centrifugal block 433. One end of the transmission rod 54 is connected to the turntable 52, and the other end is connected to the centrifugal peeling unit 43. As the centrifugal block 433 moves, the transmission rod 54 drives the turntable 52 to move, causing the torsion spring 53 to undergo elastic deformation. When the driving component 20 stops running, the connecting rod 41 stops rotating due to the lack of a power source. At this time, the torsion spring 53, due to the lack of centrifugal force, drives the turntable 52 to reset.

[0035] like Figure 4 As shown, for example, the turntable 52 has a slot 521 on its side edge that is adapted to the transmission rod 54, and the transmission rod 54 passes through the slot 521. In order to facilitate the rotation of the turntable 52 with the inertial movement of the centrifugal block 433, the slot 521 is opened on the side edge of the turntable 52, and the transmission rod 54 extends into the slot 521. At this time, the movement of the centrifugal block 433 will drive the transmission rod 54 to press against the inner wall of the slot 521, so that the turntable 52 moves with the centrifugal block 433, and drives the torsion spring 53 to elastically return to its original position.

[0036] like Figure 4 As shown, exemplarily, the blade holder 42 includes a first carrier plate 421 disposed next to the centrifuge block 433 and a second carrier plate 422 disposed next to the peeling blade 432. The first carrier plate 421 and the second carrier plate 422 are disposed opposite to each other, and the blade rod 431 passes through the first carrier plate 421 and the second carrier plate 422. Because the blade rod 431 is relatively long, in order to avoid the blade rod 431 vibrating during rotation and affecting the peeling effect of the peeling blade 432, the first carrier plate 421 and the second carrier plate 422 are respectively sleeved at both ends of the blade rod 431. The restriction of the first carrier plate 421 and the second carrier plate 422 makes it less likely for the blade rod 431 to vibrate during rotation.

[0037] like Figure 4As shown, for example, the second carrier tray 422 is provided with an opening 45 corresponding to the three centrifugal stripping units 43. The transmission rod 54 extends into the opening 45. A movable limiting member 46 is provided on any side edge of the second carrier tray 422. One end of the limiting member 46 extends into the adjacent opening 45 and corresponds to the transmission rod 54 within the opening 45. To prevent excessive movement of the centrifugal block 433, which could cause the stripping blade 432 on the blade bar 431 to contact the wire too deeply and affect the stripping effect, an opening 45 is provided on the side edge of the second carrier tray 422. The upper end of the rod 54 extends into the opening 45. At the same time, a limiting member 46 is provided on either side edge of the second carrier plate 422, which can be inserted into the opening 45 adjacent to its output end. The limiting member 46 can be a screw. By twisting the limiting member 46, the inner cavity of the conveying end of the limiting member 46 moves and abuts against the transmission rod 54 in the opening 45, thereby limiting the displacement distance of the transmission rod 54 in the opening 45, so as to avoid the centrifugal block 433 connected to the transmission rod 54 from driving the knife bar 431 to move too much, which would cause damage to the wire stripped by the stripping knife 432.

[0038] In addition, a space 451 is provided between the two opposite walls of the opening 45 for the displacement of the transmission rod 54. The space 451 is the distance that the transmission rod 54 can be displaced. As the limiting member 46 extends or retracts within the opening 45, the stripping knife 432 can strip wires of different sizes.

[0039] like Figure 4 As shown, for example, a movable torsion rod 47 is provided on one side of the centrifuge block 433. One end of the torsion rod 47 extends into the centrifuge block 433 and abuts against the blade 431 inside the centrifuge block 433. To ensure that the blade 431 can move with the centrifuge block 433, a movable torsion rod 47 is provided on one side of the centrifuge block 433. The torsion rod 47 can also be a screw. As the torsion rod 47 is twisted, one end of the torsion rod 47 moves inside the centrifuge block 433 until it abuts against the side wall of the blade 431 that extends into the inner cavity of the centrifuge block 433, so that the blade 431 is effectively limited and can move with the centrifuge block 433.

[0040] The blade shanks 431 are inclined and close together. The positioning hole 44 is located between the three blade shanks 431, so that the three stripping blades 432 can make equidistant contact with the wires inserted into the positioning hole 44. The inclined design of the blade shanks 431 makes the stripping blades 432 on the blade shanks 431 closer together, so as to facilitate the stripping of the wires by the stripping blades 432.

[0041] The transmission assembly 30 includes a drive rod 31 connected to the body 10. One end of the drive rod 31 is connected to the output shaft of the drive component 20 via a meshing transmission member 32, and the other end of the drive rod 31 is connected to the connecting rod 41. The drive component 20 is a drive cylinder. When the output shaft of the drive cylinder rotates, the meshing transmission member 32 moves accordingly, causing the drive rod 31 to drive the connecting rod 41 to rotate. The drive rod 31 and the connecting rod 41 can be connected by screws.

[0042] Specifically, the meshing transmission component 32 includes a drive gear 321 connected to the output shaft of the drive component 20 and a driven gear 322 connected to the drive rod 31. The drive gear 321 and the driven gear 322 are connected by a synchronous belt 323.

[0043] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
