Description

[Technical Field]

[0001] This utility model belongs to the technical field of rotary clamping mechanisms, and in particular relates to a rotor assembly rotary positioning mechanism. [Background Technology]

[0002] In the manufacturing process of rotor assemblies, operations such as dispensing and curing place extremely high demands on the rotational positioning accuracy and stability of the rotor assemblies. Traditional rotor assembly rotational positioning mechanisms often have several shortcomings: some mechanisms use simple clamping methods, which make it difficult to ensure the angular positioning accuracy of the rotor assembly during rotation, and are prone to transmission slippage, affecting the processing quality of processes such as dispensing; some mechanisms have cumbersome centering components, making it impossible to quickly clamp and release the rotor assembly, reducing production efficiency; at the same time, many mechanisms have poor compatibility with different specifications or models of rotor assemblies, requiring readjustment or replacement of a large number of parts when changing rotor models, increasing production and time costs. In addition, traditional mechanisms often suffer from poor rotor assembly rotational flatness due to their own structural instability during rotation, further affecting processing accuracy, and the overflow of adhesive is difficult to clean, also causing inconvenience for subsequent maintenance.

[0003] Therefore, there is an urgent need for a rotary positioning mechanism that can achieve high-precision angular positioning, stable rotary transmission, convenient clamping, and adaptability to rotor assemblies of various specifications. [Utility Model Content]

[0004] The main purpose of this utility model is to provide a rotor assembly rotation positioning mechanism that can accurately rotate and position the rotor assembly and drive it stably to meet the needs of operations such as dispensing and curing.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a rotor assembly rotation positioning mechanism, comprising a mounting plate, a driving member fixed on the mounting plate, and a rotating seat driven by the driving member to rotate horizontally; the rotating seat is provided with an upwardly penetrating conformal bearing groove for bearing shaft-like assemblies, and at least a pair of positioning transmission blocks for angular positioning and rotational transmission of the shaft-like assembly and a centering component for clamping the shaft-like assembly are provided around the conformal bearing groove.

[0006] Furthermore, the top of the contour bearing groove is provided with a stepped support groove that supports the convex ring portion of the shaft assembly, and one end of the positioning transmission block extends into the stepped support groove.

[0007] Furthermore, the upper surface of the rotating seat is provided with a radially extending slide groove, and the positioning transmission block is installed in the slide groove in an adjustable radial position.

[0008] Furthermore, the centering component includes two sub-modules symmetrically arranged in the rotating seat; each sub-module includes a mounting base fixed in the rotating seat, a support block rotatably mounted on the mounting base via a fulcrum and used to support the bottom of the convex ring portion of the shaft assembly, a centering clamping rod fixed on the support block and used to clamp or release the convex ring portion as the support block rotates, and a reset elastic element that drives the end of the support block near the conformal bearing groove to rotate upward to reset it.

[0009] Furthermore, one end of the support block extends into the conformal bearing groove and the other end is fixedly mounted with a lever arm; one end of the elastic reset member is fixed on the lever arm and the other end is fixed on a fixed seat; the centering clamp is vertically arranged on the upper surface of the support block.

[0010] Furthermore, the shaft assembly includes a shaft portion and a convex ring portion fixed to the outer periphery of the shaft portion. The convex ring portion is provided with a plurality of first grooves and second grooves distributed along the circumference. The positioning transmission block cooperates with the first groove to realize angular positioning and rotational transmission. The centering component cooperates with the second groove to realize clamping.

[0011] Furthermore, a support shaft seat is fixedly provided on the mounting plate, and a gear disk is rotatably provided on the support shaft seat via a bearing; a drive gear is provided on the rotating end of the drive component, and the drive gear meshes with the gear disk; the bottom of the rotating seat sits on the gear disk and is fixedly connected to the gear disk, and rotates synchronously with the gear disk.

[0012] Furthermore, the contoured bearing groove extends downward through the bottom of the rotating seat, and a pressure cap is provided at the bottom of the groove, the pressure cap pressing down on the rotating seat or the gear disk.

[0013] Furthermore, the rotating seat includes a first disc portion located at the bottom and a cylindrical portion located on the first disc portion; the first disc portion is fixedly connected to the gear disk, and a plurality of support balls are arranged around the mounting plate below the first disc portion, the support balls supporting the lower surface of the first disc portion.

[0014] Furthermore, a second disc portion is formed at the top of the cylindrical portion; both the first disc portion and the second disc portion have annular grooves on their upper surfaces, and the diameter of the annular grooves is larger than the diameter of the shaft assembly.

[0015] Compared with the prior art, the beneficial effects of the rotor assembly rotation positioning mechanism of this utility model are as follows:

[0016] (1) Precision rotation and angle positioning: The drive unit drives the rotating seat to rotate through the meshing transmission of the drive gear and the gear disk. The gear transmission has the characteristics of precise transmission ratio and smooth transmission, which ensures the rotation accuracy of the rotating seat and rotor assembly. The positioning transmission block cooperates with the first groove of the rotor assembly, which not only realizes angle positioning, but also ensures the power transmission during rotation, avoids slippage, and provides a precise angle reference for operations such as dispensing.

[0017] (2) Stable and reliable rotational support: The lower surface of the first disc of the rotating seat is supported by the ball bearing, which effectively ensures the flatness and stability of the rotating seat during rotation and reduces the impact of rotational shaking on machining accuracy; the support shaft supports the gear disk through the bearing and the pressure cover restricts the vertical freedom of the gear disk, further improving the stability of the overall rotating structure.

[0018] (3) Convenient and efficient clamping operation: The centering component adopts the lever principle. In the initial state, the elastic reset component keeps the centering clamping rod in the loose state. After the rotor component is placed in, it relies on its own gravity to drive the centering clamping rod to swing and achieve clamping. When it is taken out, the elastic reset component automatically resets and loosens the centering clamping rod, realizing the rapid clamping and release of the rotor component and improving the operation efficiency. The two symmetrically set sub-modules form a clamping structure to ensure uniform clamping force and improve the reliability of clamping.

[0019] (4) Good compatibility: The positioning transmission block is installed in the radially extending slide groove, and its radial position is adjustable. It can cooperate with the first groove of rotor assemblies of different specifications, and is suitable for positioning transmission of various types of rotor assemblies, which enhances the versatility of the mechanism.

[0020] (5) Easy to clean and maintain: The upper surfaces of the first and second discs of the rotating seat are provided with annular grooves with a diameter larger than that of the rotor assembly. When the glue is dispensed, the overflowing glue will gather in the annular grooves, preventing the glue from spilling indiscriminately and making it easy for operators to clean up and keep the mechanism clean.

[0021] (6) Precise angle monitoring: The sensor on the rotary seat works in conjunction with the sensor on the mounting plate to sense the rotation angle information of the rotary seat in real time, which facilitates precise control and adjustment of the rotation angle to meet the requirements of high-precision processing.

[0022] (7) Reasonable structural layout: The rotating seat is indirectly connected to the drive component through the gear disk. The drive component is installed on the lower surface of the mounting plate, which saves installation space. At the same time, the layout of each component is compact and the transmission path is clear, which is conducive to the assembly, debugging and maintenance of the mechanism.

Detailed Implementation Methods

[0033] Example 1:

[0034] Please refer to Figures 1-6 This embodiment is a rotor assembly rotation positioning mechanism 100, which is used to position shaft assemblies and drive them to rotate so as to perform operations such as dispensing and curing.

[0035] In this embodiment, the shaft assembly is a rotor assembly 200, which includes a shaft portion 201 and a convex ring portion 202 fixed on the outer periphery of the shaft portion 201. The convex ring portion 202 is provided with a plurality of first grooves 203 and second grooves 204 distributed along the circumference.

[0036] This embodiment of a rotor assembly rotation positioning mechanism 100 includes a mounting plate 1, a driving member 2 fixed to the mounting plate 1, and a rotating seat 3 driven by the driving member 2 to rotate horizontally. The rotating seat 3 is provided with an upwardly penetrating conformal bearing groove 31 for supporting the rotor assembly 200. Around the conformal bearing groove 31, at least a pair of positioning transmission blocks 4 are provided to cooperate with a first groove 203 to achieve angular positioning and rotational transmission, and a centering component 5 is provided to cooperate with a second groove 204 to clamp the rotor assembly 200.

[0037] A support shaft seat 11 is fixedly mounted on the mounting plate 1, and a gear disk 6 is rotatably mounted on the support shaft seat 11 via a bearing 12. A drive component 2 is mounted on the lower surface of the mounting plate 1, with its rotating end extending into the upper surface of the mounting plate 1 and fixedly mounted with a drive gear 21. The drive gear 21 meshes with the gear disk 6. The bottom of the rotating seat 3 rests on and is fixedly connected to the gear disk 6, rotating synchronously with it.

[0038] To restrict the vertical freedom of the gear disk 6, in this embodiment, the contoured bearing groove 31 extends downward through the bottom of the rotating seat 3, and a pressure cap 7 is provided at the bottom of the groove. The pressure cap 7 presses down on the rotating seat 3, thereby pressing down on the gear disk 6, and is locked to the top of the support shaft seat 11 with screws. In other embodiments, the pressure cap 7 can also be used to directly press the gear disk 6.

[0039] The rotating base 3 includes a first disc portion 32 located at the bottom and a cylindrical portion 33 located on the first disc portion 32. The first disc portion 32 is fixedly connected to the gear disk 6. A plurality of support balls 8 are arranged around the lower surface of the first disc portion 32 on the mounting plate 1. The support balls 8 support the lower surface of the first disc portion 32, ensuring that the rotating base 3 can maintain reliable and stable flatness and stability during rotation, thus ensuring dispensing accuracy. A sensing plate 34 is also provided on the first disc portion 32, and a sensor 35 is provided on the mounting plate 1 to sense the signal of the sensing plate 34 and sense the rotation angle information of the rotating base 3.

[0040] A second disc portion 331 is formed at the top of the cylinder portion 33. Both the first disc portion 32 and the second disc portion 331 have annular grooves 332 on their upper surfaces. The diameter of the annular grooves 332 is larger than the diameter of the rotor assembly 200 so that when the rotor assembly 200 is glued, the glue will not spill indiscriminately after overflowing, but will collect in the annular grooves 332, making it easy for operators to clean up.

[0041] The contoured support groove 31 is recessed from the upper surface of the second disk portion 331 and extends downward to the lower surface of the first disk portion 32. The contoured support groove 31 is provided to avoid the section structure below the convex ring portion 202 of the rotor assembly 200.

[0042] The top of the conformal bearing groove 31 is provided with a stepped support groove 333 for supporting the convex ring portion 202 of the rotor assembly 200, and one end of the positioning transmission block 4 extends into the stepped support groove 333. The upper surface of the second disc portion 331 is provided with a radially extending slide groove 334, and the radial position of the positioning transmission block 4 is adjustablely installed in the slide groove 334 to be suitable for positioning transmission of rotor assemblies of various specifications or models.

[0043] The centering assembly 5 includes two sub-modules 5A and 5B, symmetrically arranged in the rotating seat 3 to form a clamping structure for the convex ring 202, thereby centering the rotor assembly. Each sub-module includes a mounting base 51 fixed within the rotating seat 3; a support block 52 rotatably mounted on the mounting base 51 via a fulcrum and used to support the bottom of the convex ring 202; a centering clamping rod 53 fixed to the support block 52 and clamping or releasing the convex ring 202 as the support block 52 rotates; and a reset elastic member 54 that drives one end of the support block 52 near the contoured bearing groove 31 to rotate upwards and reset it. One end of the support block 52 extends into the contoured bearing groove 31, and the other end is fixedly mounted with a lever arm 521. One end of the elastic reset member 54 is fixed to the lever arm 521, and the other end is fixed to a fixed seat 55, which is fixed to the cylinder portion 33 or the first disc portion 32. The centering clamp 53 is set in an upright position on the upper surface of the support block 52.

[0044] In the initial state, the elastic reset member 54 pulls down on end A of the support block 52 (one end of the lever arm 521), causing end B of the support block 52 (the end extending into the conformal bearing groove 31) to tilt upwards, and the centering clamp 53 to be in an outward-tilting, released state. When the rotor assembly 200 is lowered into the conformal bearing groove 31, under its own gravity, the lower surface of the convex ring 202 drives end B of the support block 52 to rotate downwards, thereby driving the centering clamp 53 to swing inwards to an upright state and engage in the second groove 204 of the convex ring 202, and the two centering clamps 53 switch to the upright position. In the clamping state, the rotor assembly 200 is clamped; and during the insertion of the rotor assembly 200, the positioning transmission block 4 gradually extends into the first groove 203. When the rotor assembly 200 is in place, the positioning transmission block 4 is fully inserted into the first groove 203, thereby realizing the clamping and transmission positioning of the rotor assembly 200; the driving component 2 drives the rotor assembly 200 to rotate, in conjunction with the glue dispensing operation; after the glue dispensing of the rotor assembly 200 is completed, the rotor assembly 200 is taken out upwards, and under the elastic force of the elastic reset component 54, the support block 52 is reset, and the centering clamping rod 53 switches to the released state.

[0045] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
