Description

Technical Field

[0001] The invention relates to a two-end pressing synchronous rotating device. Background Art

[0002] After stator 1 is assembled, the terminal assembly 2 is typically mounted on the stator 1. The electrodes (e.g., three-phase electrodes) of stator 1 are led out through the terminal assembly 2. The terminal assembly 2 is annular and has multiple terminal components 2a disposed on its circumference. Multiple electrodes 2b are disposed on one axial end face of the terminal assembly 2, and a clamping portion 2c is disposed on the other axial end face of the terminal assembly 2.

[0003] When assembling the stator 1 and the terminal assembly 2, the stator 1 is manually placed on a turntable. The clamping portion 2c of the terminal assembly 2 is inserted into the clamping slot 1b provided on the stator core 1a to pre-position the stator. The stator 1 is then pre-positioned by inserting the multiple copper wires 1c from the stator 1 into the corresponding terminal components 2a. The copper wires 1c are then bent down with pliers, and the excess copper wire is trimmed. The copper wires 1c are then welded to the terminal components 2a. After welding, the copper wires 1c are secured to the terminal components 2a, and the clamping portion 2c is engaged with the clamping slot 1b, securing the stator 1 and the terminal assembly 2 together to form a stator assembly 3.

[0004] Regarding the assembly of the stator 1 and the terminal assembly 2, since the entire assembly process of both is completed manually, not only is the assembly efficiency low, but also, since the stator 1 and the terminal assembly 2 are only pre-positioned by the clamping portion 2c and the clamping slot 1b, the accuracy of this pre-positioning cannot be guaranteed, resulting in deflection or movement between the stator 1 and the terminal assembly 2 during the assembly process, resulting in low assembly accuracy. Summary of the Invention

[0005] The present invention provides a two-end pressing synchronous rotation device, which is suitable for combined parts that need to be pressed on both sides of the axial direction to maintain the shape and position, and the double-sided pressing positions have in-situ requirements. After pressing, the double-sided synchronous rotation indexing is performed for operation and processing.

[0006] The technical solutions to the above problems are as follows:

[0007] The two-end top-pressing synchronous rotation device includes:

[0008] Rotary indexing mechanism;

[0009] A transmission component capable of axial movement and rotational motion;

[0010] A pressing assembly is fixed to the other end of the transmission assembly, and moves and / or rotates with the transmission assembly;

[0011] An axial drive assembly for driving the axial displacement of the transmission assembly, the axial drive assembly cooperates with the transmission assembly;

[0012] The rotary pressing assembly is located on one side of the pressing assembly, and the axial driving assembly drives the transmission assembly to move the transmission assembly closer to or away from the rotary pressing assembly;

[0013] The transmission assembly or the rotary pressing assembly is connected to the rotary indexing mechanism.

[0014] After the stator and the terminal assembly are pre-positioned, both axial sides of the stator assembly need to be pressed to maintain the shape and position, and the initial pressing position must be a specific position. The stator assembly is pressed between the pressing assembly and the rotating pressing assembly by the synchronous rotation device of the two ends of the present invention. When one side of the rotary indexing mechanism rotates, the other side always remains pressed and follows the synchronous rotation. After one rotation, the pressing assembly and the rotating pressing assembly are respectively reset to their initial positions and wait for the next product to perform the same operation. The present invention is an automatic device, in which the active and driven sides are pressed at specific positions, rotate synchronously, and automatically reset to their original positions after one cycle. The driven component does not have additional power. The workpiece is always in a constrained state during the entire operation and processing process, and the product shape can be well maintained.

[0031] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] like Figures 2 to 7 As shown, the two-end pressing synchronous rotation device of the present invention includes a rotary indexing mechanism A, a transmission assembly B, a pressing assembly C, an axial drive assembly D, and a rotary pressing assembly E. The following describes each part and the relationship between them in detail:

[0033] In this embodiment, the transmission assembly B is preferably connected to the rotary indexing mechanism A, and the transmission assembly B can perform axial movement and rotational motion.

[0034] The rotary indexing mechanism A includes a driving mechanism 10, a first sleeve 11, a transmission component 12, and a first support 13. The first sleeve 11 is connected to the driving mechanism 10. A waist-shaped hole or a strip hole 11a is provided on the circumference of the first sleeve 11. The first sleeve 11 is rotatably mounted on the first support 13. The transmission component 12 is connected to the transmission assembly B. The transmission component 12 slides in conjunction with the waist-shaped hole or the strip hole 11a.

[0035] In this embodiment, the drive mechanism 10 includes a motor and a belt transmission mechanism. The output end of the motor is connected to the driving pulley of the belt transmission mechanism, and the driven pulley of the belt transmission mechanism is connected to the first sleeve 11. The transmission component B is loosely fitted with the first sleeve 11, and can move axially along the first sleeve 11 when subjected to an axial force. The transmission component 12 is preferably a pin shaft, and a mounting hole is provided on the circumference of the transmission component B. The transmission component 12 is fitted with the mounting hole on the circumference of the transmission component B. The end of the transmission component 12 is slidingly fitted with the waist-shaped hole or strip-shaped hole 11a. When the drive mechanism 10 drives the first sleeve 11 to rotate, the first sleeve 11 sequentially transmits torque to the transmission component 12 and the transmission component B, thereby rotating the transmission component B. The first support 13 is provided with an axial hole, and a first bearing is installed in the axial hole. The first sleeve 11 passes through the first bearing, so that the first sleeve 11 and the first support 13 form a rotatable fit.

[0036] In this embodiment, the rotary indexing mechanism A further includes a sensing component 14 and a sensor 15 for detecting one rotation of the sensing component 14. One end of the sensing component 14 is fixed to the outer circumference of the first sleeve 11, and one end of the first sleeve 11 is exposed outside the first support 13. Therefore, the sensing component 14 is preferably fixed to one end of the first sleeve 11 using screws. The sensor 15 is located on one side of the first sleeve 11. Since the sensing component 14 rotates with the first sleeve 11, when the position of the sensing component 14 corresponds to the position of the sensor 15, the sensing component 14 is at its home position. When the sensing component 14 rotates one rotation and the sensor 15 detects the sensing component 14 again, this represents one rotation of the stator assembly 3.

[0037] Since there are twelve copper wires 1c and twelve terminal blocks 2a on the stator assembly 3, each operation of the drive mechanism 10 rotates the stator assembly 3 30°. With each rotation, one set of copper wires 1c and terminal blocks 2a is welded by the welding robot, the copper wires 1c are bent by the bending mechanism G, and the excess portion of the bent copper wires 1c is trimmed off by the shearing mechanism F. After the drive mechanism 10 operates twelve times, the first sleeve 11 sequentially drives the transmission assembly B, the pressing assembly C, and the rotary pressing assembly E to rotate one full revolution, completing the processing of all twelve sets of copper wires 1c and terminal blocks 2a. When the sensing component 14 returns to its original position, indicating that all sets of copper wires 1c and terminal blocks 2a on the stator assembly 3 have been processed, the drive mechanism 10 stops, and the processed stator assemblies 3 are unloaded and the stator assemblies 3 to be processed are loaded for the next cycle of operation.

[0038] In this embodiment, the transmission component B is required to drive the stator assembly 3 to move axially and rotationally. Therefore, one end of the transmission component B forms an axial sliding fit with the rotary indexing mechanism A, and the transmission component B and the rotary indexing mechanism A also form a circumferential connection.

[0039] The transmission assembly B includes a transmission shaft 20, one end of which forms an axial sliding fit with the rotary indexing mechanism A, and the transmission shaft 20 and the rotary indexing mechanism A also form a circumferential connection, wherein one end of the transmission shaft 20 is clearance-fitted with the first sleeve 11, and the mounting hole is provided on the circumferential surface of the transmission shaft 20. After the transmission component 12 is fitted with the mounting hole, the transmission component 12 and the transmission shaft 20 are circumferentially fixed.

[0040] The other end of the drive shaft 20 is provided with a first radial component 21. This first radial component 21 is disc-shaped and is integrally formed with the other end of the drive shaft 20. The first radial component 21 is also connected to the pressing assembly C. The drive shaft 20 is also provided with a second radial component (not shown). The second radial component is preferably a retaining ring, which is engaged in an annular groove provided on the drive shaft 20.

[0041] A portion of the axial drive assembly D is located between the first radial component 21 and the second radial component. When the axial drive assembly D applies force to the first radial component 21, the axial drive assembly D drives the transmission assembly B to advance. When the axial drive assembly D applies force to the second radial component, the axial drive assembly D drives the transmission assembly B to retreat.

[0042] The pressing component C is fixed to the other end of the transmission component B, and the pressing component C moves and / or rotates with the transmission component B; the pressing component C is used to accommodate a portion of the stator assembly 3. For example, one end of the stator 1 is matched with the pressing component C. When the pressing component C is subjected to an axial force, the stator assembly 3 moves axially following the pressing component C. When the pressing component C is subjected to a rotational force, the stator assembly 3 rotates following the pressing component C.

[0043] The pressure assembly C includes an adapter sleeve 30 with an opening at one end and a base plate 31 at the other end. The base plate 31 is fixed to the transmission assembly B. The adapter sleeve 30 includes an inner ring 32 fixed to the base plate. A fitting space 32a is formed between the adapter sleeve 30 and the inner ring 32 for fitting the stator 1. Since the stator 1 itself has an annular structure, the stator 1 is inserted into the fitting space 32a.

[0044] The pressure assembly C also includes a guide mechanism for guiding the stator assembly 3, which moves axially with the pressure assembly C. The guide mechanism includes a bearing assembly 33 and a guide sleeve 34. At least a portion of the guide sleeve 34 is located in the inner bore of the bearing assembly and is fixed to the bearing assembly. In this embodiment, the bearing assembly 33 is composed of a bearing seat and a bearing mating with the bearing seat. The guide sleeve 34 is fixed to the bearing in the bearing assembly 33. A guide bar (not shown) is provided on the inner wall surface of the guide sleeve 34. The outer peripheral surface of the stator core 1a is provided with an axially extending engaging groove 1d. The guide bar is inserted into the engaging groove 1d, forming a circumferential positioning between the guide bar and the stator 1. The inner bore of the guide sleeve 34 is a stepped hole. When the adapter sleeve 30 abuts the stepped surface of the inner bore of the guide sleeve 34, the adapter sleeve 30 and the guide sleeve 34 transmit rotational torque through friction.

[0045] Of course, a groove can also be provided on the axial end surface of the adapter sleeve 30, and a protrusion can be provided on the stepped surface of the inner hole of the guide sleeve 34, so that the groove and the protrusion cooperate to transmit the rotational torque. In addition, the guide strip can be directly provided on the inner wall surface of the adapter sleeve 30 without providing the guide sleeve 34.

[0046] The axial drive assembly D is used to drive the axial displacement of the transmission assembly B and cooperates with the transmission assembly B. The axial drive assembly D includes a linear actuator 40 and a transmission plate 41. The transmission plate 41 is fixed to the power output end of the linear actuator 40. The transmission plate 41 has a through hole. After the transmission plate 41 is loosely inserted into the transmission assembly B through the through hole, the transmission assembly B forms an axial limit on each end of the transmission plate 41.

[0047] The linear drive 40 can be one of a pneumatic cylinder, a hydraulic cylinder or an electric screw, and the transmission plate 41 is loosely mounted on the transmission shaft 20. The linear drive 40 drives the transmission plate 41 to move axially along the transmission shaft 20. The first radial component 21 and the second radial component respectively cooperate with the transmission plate 41, thereby forming axial limits on the transmission plate 41.

[0048] The axial drive assembly D also includes a bearing 42 and an interface sleeve 43. The bearing 42 is installed on the transmission assembly B. One end of the interface sleeve 43 is sleeved on the bearing 42 and fixed to the bearing 42. The bearing 42 forms a support for the interface sleeve 43 so that the interface sleeve 43 and the transmission shaft 20 are clearance-matched. The other end of the interface sleeve 43 is matched with the transmission plate 41 so that the transmission plate 41 is loosely sleeved on the transmission assembly B. For example, the other end of the interface sleeve 43 is provided with a support portion 44, and the through hole on the transmission plate 41 is a stepped hole, and the large diameter hole of the stepped hole is clearance-matched with the support portion 44.

[0049] The rotary pressing component E is located on one side of the pressing component C, and the axial driving component D drives the transmission component B to move so that the transmission component B moves closer to or away from the rotary pressing component E.

[0050] Because stator assembly 3 is mounted on pressing assembly C, when transmission assembly B, driven by axial drive assembly D, drives pressing assembly C toward rotating pressing assembly E, the ends of stator assembly 3 eventually come into contact with pressing assembly C and rotating pressing assembly E, respectively. When transmission assembly B is rotated by torque, it transmits the torque through pressing assembly C and stator assembly 3 to rotating pressing assembly E, causing rotating pressing assembly E to passively rotate along with stator assembly 3.

[0051] In this embodiment, the rotary pressing assembly E comprises a support base 50, a rotating shaft 52, and a passive pressing head 53. The support base 50 is provided with a mounting hole 51. One end of the rotating shaft 52 is loosely fitted into the mounting hole 51, allowing the rotating shaft 52 to rotate relative to the support base 50. The passive pressing head 53 is fixed to the other end of the rotating shaft 52. Because the stator 1 is mated with the pressing assembly C, the passive pressing head 53 is designed to mate with the terminal assembly 2. When the passive pressing head 53 abuts the terminal assembly 2 and the transmission assembly B is rotated by torque, the transmission assembly B transmits the torque to the rotating shaft 52 through the pressing assembly C, the stator assembly 3, and the passive pressing head 53, ultimately causing the rotary pressing assembly E to passively rotate along with the stator assembly 3.

[0052] Preferably, the mounting hole 51 is a through hole for the rotating shaft 52 to move axially and pass through. The rotary pressing assembly E also includes a spring 54 and a positioning component 55. The spring 54 is sleeved on the rotating shaft 52. One end of the spring 54 cooperates with the support seat 50, and the other end of the spring 54 cooperates with the passive pressing head 53. One end of the positioning component 55 is fixed to the support seat 50; one end of the rotating shaft 52 passes through the mounting hole 51 to be exposed to the outside of the mounting hole 51, and one end of the rotating shaft 52 is provided with a slot 52a. When the other end of the positioning component 55 cooperates with the slot 52a, the rotating shaft 52 is circumferentially fixed.

[0053] Because the rotating shaft 52 is circumferentially restricted by the cooperation of the positioning member 55 and the slot 52a, when the transmission assembly B transmits the axial force it receives to the passive pressing head 53 via the pressing assembly C and the stator assembly 3, the rotating shaft 52 can only move axially along the mounting hole 51 and cannot rotate. As the rotating shaft 52 continues to move axially, the cooperation between the positioning member 55 and the slot 52a is released. At this time, if the rotating shaft 52 is subjected to torsional force, it can rotate. The cooperation between the positioning member 55 and the slot 52a prevents the stator assembly 3 from rotating in the absence of the rotational torque of the rotary indexing mechanism A.

[0054] When the rotating shaft 52 passively rotates one circle along with the rotary indexing mechanism A, the slot 52a returns to the position corresponding to the positioning component 55. If the axial drive component D drives the transmission component B to retreat, the pressing component C and the stator assembly 3 retreat along with the transmission component B. At this time, under the tension of the spring 54, the spring 54 pushes the passive pressing head 53 to move the rotating shaft 52 toward the stator assembly 3, so that the positioning component 55 and the slot 52a are re-engaged.

[0055] This embodiment further includes a bending mechanism G for bending the copper wire 1c on the stator assembly 3 as the stator assembly 3 rotates. The bending mechanism G includes a blocking bar 60, one end of which extends toward the circumference of the stator assembly 3. When the stator assembly 3 rotates, the copper wire 1c is passively bent due to the blocking effect of the blocking bar 60. Preferably, the blocking bar 60 is fixed to the bearing assembly 33.

[0056] The device further includes a shearing mechanism F, which comprises a scissor base 70, scissors 71, and a shearing translation mechanism 72. Scissors 71 are used to shear off excess copper wire 1c. After the copper wire 1c is bent by the blocking bar 60, the excess head is sheared off by the scissors 71. Scissors 71 are preferably pneumatic scissors 71. Scissors 71 are fixed to a scissor base 70, which is fixed to the shearing translation mechanism 72. The translation mechanism 72 can drive the scissor base 70 to move the scissors 71 toward or away from the copper wire 1c. The translation mechanism 72 can be a pneumatic cylinder, a hydraulic cylinder, or an electric screw.

[0057] The present invention is not limited to the above embodiments, for example:

[0058] The connection between the transmission assembly B and the rotary indexing mechanism A can also be achieved by: the transmission shaft 20 is connected to the first sleeve 11 through a spline, which can also achieve both axial movement of the transmission shaft 20 and transmission of torque.

[0059] The rotary indexing mechanism A can also be connected to the rotary pressing assembly E. That is, the driving mechanism 10 is connected to the rotating shaft 52, and the other relationships remain unchanged.

[0060] Finally, it should be noted that the above embodiments are merely preferred embodiments of the present invention and are used to illustrate the technical solutions of the present invention, rather than limiting them, let alone limiting the scope of protection of the present invention. Although the invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of protection of the claims.
