A positioning mechanism for a motor rotor winding machine

Abstract

This utility model discloses a positioning mechanism for a motor rotor winding machine, relating to the field of winding equipment technology. It includes a rotor fixing mechanism and a first mounting base. The rotor fixing mechanism comprises a sleeve, a clamping tube, and a second driving component. In use, one end of the rotor is inserted into the clamping end of the clamping tube. The second driving component drives the clamping tube to move towards the control end, causing relative displacement between the first and second contact surfaces, squeezing the clamping end and deforming it inwards, thus clamping the rotor end. The second driving component drives the clamping tube to move towards the clamping end, gradually resetting the clamping end and releasing the clamping of the rotor end. Because the clamping is achieved through the axial movement of the clamping tube, the requirements for the circumferential installation and movement space of the clamping tube are smaller, resulting in less interference with the winding operation of the winding mechanism of the winding machine.

Description

Technical Field

[0001] This utility model relates to the field of winding equipment technology, specifically a positioning mechanism for a motor rotor winding machine. Background Technology

[0002] In today's society, motors are widely used in various products. A typical motor uses an electric current to create an induced magnetic field, which interacts with an internal permanent magnet to produce rotational motion. Besides directly providing rotational motion, the rotational mechanical energy output by a motor can be combined with different mechanisms to convert into linear or vibratory motion, making it a versatile device.

[0003] The rotor is one of the components of a motor. During its production and processing, enameled wire needs to be wound onto the rotor. In the existing rotor winding machine, the rotor is generally fixed by a three-jaw chuck during winding. Since the three-jaw chuck needs to drive the three jaws from three circumferential directions, the required installation space and operating space are relatively large.

[0004] Therefore, a positioning mechanism for a motor rotor winding machine is needed. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model solves the problem using the following technical structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A positioning mechanism for a motor rotor winding machine includes: a rotor fixing mechanism and a first mounting base. The rotor fixing mechanism includes a sleeve, a clamping tube, and a second driving member. The sleeve is disposed on the first mounting base, the clamping tube passes through the sleeve, and the second driving member is used to drive the clamping tube and the sleeve to move relative to each other along the axial direction of the clamping tube.

[0008] One end of the clamp tube is a clamping end, and the other end is a control end. The clamp tube is provided with a plurality of deformation holes, which extend from the clamping end to the control end. The plurality of deformation holes are distributed circumferentially on the ring side of the clamp tube.

[0009] The clamping end is provided with a first contact surface on the outer side of the circumference. The first contact surface extends obliquely from the clamping end toward the control end, and the oblique direction is the axial direction of the clamping tube.

[0010] A second contact surface is provided on the inner side of one end of the sleeve near the clamping end, and the extension direction of the second contact surface is the same as the extension direction of the first contact surface.

[0011] It also includes a first driving member, which is used to drive the rotor fixing mechanism to move linearly along the axial direction of the clamp tube on the first mounting base.

[0012] The first contact surface is annular.

[0013] The second contact surface is annular.

[0014] The deformable holes are evenly distributed around the circumference.

[0015] The first mounting base is provided with a linear track, and the rotor fixing mechanism further includes a slide block, which is slidably disposed on the linear track, and the sleeve is rotatably disposed on the slide block.

[0016] The first mounting base is equipped with limiters at both ends of the linear track.

[0017] The rotor fixing mechanism also includes a turntable and a slotted optical coupler. The turntable is coaxially sleeved on the outside of the sleeve. The circumferential side of the turntable is evenly provided with several grooves. The slotted optical coupler is disposed on the slide block. The circumferential side of the turntable is disposed inside the slotted optical coupler.

[0018] The sleeve is mounted on the slide block via a bearing.

[0019] The outer surface of the sleeve near the clamping end is a conical surface.

[0020] The above-described structure of this utility model can achieve the following beneficial effects:

[0021] In use, one end of the rotor is inserted into the clamping end of the clamping tube. The second driving component drives the clamping tube to move towards the control end, causing the first and second contact surfaces to shift relative to each other, squeezing the clamping end and deforming it inward, thus clamping the rotor end. The second driving component drives the clamping tube to move towards the clamping end, and the clamping end gradually returns to its original position, thereby releasing the clamping of the rotor end. Since the clamping of the rotor end is achieved through the axial movement of the clamping tube, the requirements for the circumferential installation space and movement space of the clamping tube are small, resulting in less interference with the winding operation of the winding mechanism of the winding machine.

[0027] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0028] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims and accompanying drawings of this utility model are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such processes, methods, products or devices.

[0029] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0030] refer to Figures 1-3 The positioning mechanism of a motor rotor winding machine shown includes: a rotor fixing mechanism 1 and a first mounting base 2. The rotor fixing mechanism 1 includes a sleeve 11, a clamping tube 12 and a second driving member. The sleeve 11 is disposed on the first mounting base 2, the clamping tube 12 passes through the sleeve 11, and the second driving member is used to drive the clamping tube 12 and the sleeve 11 to move relative to each other along the axial direction of the clamping tube 12.

[0031] One end of the clamp tube 12 is the clamping end, and the other end is the control end (the second driving component can be a structure such as a cylinder. By connecting the output end of the cylinder to the control end of the clamp tube 12, the cylinder performs work, causing the clamp tube 12 to move inside the sleeve 11, thereby realizing the relative movement between the clamp tube 12 and the sleeve 11). The clamp tube 12 is provided with a number of deformation holes 121, which extend from the clamping end to the control end. The number of deformation holes 121 are circumferentially distributed on the ring side of the clamp tube 12 (the design of the deformation holes 121 enables the clamping end to have the ability to deform toward or away from the axis of the clamp tube 12, and the clamping end has a certain elastic deformation capability).

[0032] A first contact surface 122 is provided on the outer side of the clamping end. The first contact surface 122 extends obliquely from the clamping end to the control end, and the oblique direction is the axial direction of the clamping tube 12.

[0033] A second contact surface 111 is provided on the inner side of the end of the sleeve 11 near the clamping end. The extension direction of the second contact surface 111 is the same as the extension direction of the first contact surface 122.

[0034] Based on the above structure, in use, one end of the rotor is inserted into the clamping end of the clamping tube 12. The clamping tube 12 is driven to move towards the control end by the second driving member, causing the first contact surface 122 and the second contact surface 111 to be displaced relative to each other, thus squeezing the clamping end and deforming the clamping end inward (the clamping end deforms in the direction of the axis of the clamping tube 12), thereby completing the clamping of the rotor end. The second driving member drives the clamping tube 12 to move towards the clamping end, and the clamping end gradually resets (the clamping end deforms away from the axis of the clamping tube 12), thereby releasing the clamping of the rotor end. Since the clamping of the rotor end is achieved through the axial movement of the clamping tube 12, the requirements for the circumferential installation space and movement space of the clamping tube 12 are small, and the interference with the winding operation of the winding mechanism of the winding machine is small.

[0035] This application also includes a first driving member, which is used to drive the rotor fixing mechanism 1 to move linearly along the axial direction of the clamp tube 12 on the first mounting base 2. The first driving member adjusts the position of the rotor fixing mechanism 1 and adjusts the fixed position of the rotor. When the rotor is wound, the two parts of this application can be used to clamp and fix the rotor at both ends respectively. Therefore, by driving the rotor fixing mechanism 1 to move by the first driving member, it is convenient to insert the two ends of the rotor into the clamp tubes 12 on both sides to achieve clamping of the two ends of the clamp tubes 12.

[0036] Further optimization involves ensuring that all parts of the clamping end deform synchronously, with the first contact surface 122 and the second contact surface 111 both being annular, and a number of deformation holes 121 being evenly distributed around the circumference.

[0037] like Figure 2As shown, a linear track 21 is provided on the first mounting base 2, and the rotor fixing mechanism 1 also includes a slide block 13. The slide block 13 is slidably disposed on the linear track 21, and the sleeve 11 is rotatably disposed on the slide block 13. (In order to realize the rotation of the clamped rotor so as to facilitate the winding of the rotor, a motor, belt and pulley can be provided to drive the sleeve 11 to rotate. A limiting structure is provided between the sleeve 11 and the clamping tube 12 so that the clamping tube 12 and the sleeve 11 cannot rotate relative to each other, thereby causing the sleeve 11 to rotate, causing the clamping tube 12 to rotate, and causing the clamped rotor to rotate.) The first mounting base 2 is provided with limiters 22 at both ends of the linear track 21. Thus, the first driving member drives the slide block 13 to slide on the linear track 21, causing the clamping end to move along the axial direction of the clamping tube 12. The limiters 22 at both ends of the linear track 21 limit and buffer the movement of the slide block 13.

[0038] like Figure 4 As shown, the rotor fixing mechanism 1 also includes a turntable 14 and a slotted optical coupler 15. The turntable 14 is coaxially sleeved on the outside of the sleeve 11. The circumferential side of the turntable 14 is evenly provided with a number of grooves 141. The slotted optical coupler 15 is disposed on the slide block 13. The circumferential side of the turntable 14 is disposed inside the slotted optical coupler 15. In this way, the sleeve 11, the rotor and the turntable 14 rotate synchronously. By monitoring the grooves 141 of the turntable 14 through the slotted optical coupler 15, the rotation speed and rotation angle of the rotor can be obtained in real time.

[0039] A further optimization is that the sleeve 11 is mounted on the slide block 13 via a bearing, reducing the friction between the sleeve 11 and the slide block 13; and as... Figure 3 As shown, the outer surface of the sleeve 11 near the clamping end is a conical surface, thus making the end of the sleeve 11 conical to reduce interference with the winding mechanism.

[0040] The above are merely preferred embodiments of this application, and the present invention is not limited to the above embodiments. It is understood that other improvements and variations that can be directly derived or conceived by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included within the protection scope of the present invention.
