Description

Technical Field

[0001] This utility model relates to the field of winding equipment technology, specifically 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 method of fixing the rotor during winding is relatively simple. When the rotor is rotating at high speed and winding the wire, the rotor rotation is unstable, which affects the winding effect.

[0004] Therefore, 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 motor rotor winding machine includes: a first mounting base and a second mounting base, the second mounting base being disposed on one side of the first mounting base, and both the second mounting base and the first mounting base being provided with a rotor fixing mechanism;

[0008] The first mounting base is provided with a first driving member, which is used to drive the rotor fixing mechanism on the first mounting base to move closer to or away from one side of the second mounting base;

[0009] The two rotor fixing mechanisms respectively clamp both ends of the rotor;

[0010] The second mounting base is provided with a second driving member, which is used to drive the rotors clamped on the two rotor fixing mechanisms to rotate.

[0011] The rotor fixing mechanism includes a sleeve, a clamp tube, and a third driving member. The sleeve is disposed on the second mounting base or the first mounting base, the clamp tube passes through the sleeve, and the third driving member is used to drive the clamp tube and the sleeve to move relative to each other along the axial direction of the clamp tube.

[0012] The clamping tubes of the two rotor fixing mechanisms are coaxially arranged;

[0013] The ends of the two clamping tubes that are close to each other are the clamping ends, and the ends of the two clamping tubes that are far apart from each other are the control ends. The clamping tubes are provided with a plurality of deformation holes that extend from the clamping ends to the control ends and are distributed in a circular pattern on the circumferential side of the clamping tubes.

[0014] 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.

[0015] 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.

[0016] The first contact surface is annular.

[0017] The second contact surface is annular.

[0018] The deformable holes are evenly distributed around the circumference.

[0019] 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.

[0020] The first mounting base is equipped with limiters at both ends of the linear track.

[0021] 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.

[0022] The sleeve is mounted on the slide block via a bearing.

[0023] The outer surface of the sleeve near the clamping end is a conical surface.

[0024] The above-described structure of this utility model can achieve the following beneficial effects:

[0025] In use, the rotor is placed between two rotor fixing mechanisms. The first driving component drives the rotor fixing mechanism on the first mounting base to move to one side of the second mounting base, adjusting the distance between the two rotor fixing mechanisms so that the two rotor fixing mechanisms clamp the two ends of the rotor respectively. During winding, the second driving component drives the clamped rotor to rotate, assisting the winding mechanism in winding the rotor. Since both ends of the rotor are clamped and fixed by the two rotor fixing mechanisms, the axial fixation of the rotor is ensured, preventing the rotor from swinging during winding and improving the quality of rotor winding.

[0032] 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.

[0033] 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.

[0034] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0035] refer to Figures 1-2 The motor rotor winding machine shown includes: a first mounting base 2, a second mounting base 3, and a winding mechanism (the winding mechanism is a prior art). The second mounting base 3 is disposed on one side of the first mounting base 2, and a rotor fixing mechanism 1 is provided on both the second mounting base 3 and the first mounting base 2.

[0036] The first mounting base 2 is provided with a first driving component, which is used to drive the rotor fixing mechanism 1 on the first mounting base 2 to move closer to or away from one side of the second mounting base 3.

[0037] Two rotor fixing mechanisms 1 respectively clamp the two ends of the rotor;

[0038] The second mounting base 3 is provided with a second driving component, which is used to drive the rotors clamped on the two rotor fixing mechanisms 1 to rotate.

[0039] The winding mechanism is used to wind the clamped rotor.

[0040] Based on the above structure, during use, the rotor (such as...) Figure 1 As shown, the rotor is placed between two rotor fixing mechanisms 1. The rotor fixing mechanism 1 on the first mounting base 2 is driven by the first driving member to move to one side of the second mounting base 3, adjusting the distance between the two rotor fixing mechanisms 1 so that the two rotor fixing mechanisms 1 clamp the two ends of the rotor respectively. During winding, the clamped rotor is driven to rotate by the second driving member, assisting the winding mechanism in winding the rotor. Since both ends of the rotor are clamped and fixed by the two rotor fixing mechanisms 1, the axial fixation of the rotor is ensured, so that the rotor will not swing during winding, thus improving the quality of rotor winding.

[0041] like Figures 2-5As shown, the rotor fixing mechanism 1 includes a sleeve 11, a clamping tube 12, and a third driving member. The sleeve 11 is mounted on the second mounting base 3 or the first mounting base 2. The clamping tube 12 passes through the sleeve 11. The third 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. The clamping tubes 12 of the two rotor fixing mechanisms 1 are coaxially arranged. The ends of the two clamping tubes 12 that are close to each other are the clamping ends, and the ends of the two clamping tubes 12 that are far apart from each other are the control ends (the third driving member can be composed of a cylinder or other structure. By connecting the output end of the cylinder to the control end of the clamping tube 12, the cylinder performs work, causing the clamping tube 12 to move within the sleeve 11, thereby realizing the relative movement between the clamping tube 12 and the sleeve 11). The clamping tube 12 is provided with a plurality of deformation holes 121, which extend from the clamping end to the control end. The plurality of deformation holes 121 are circumferentially distributed on the annular side of the clamping tube 12 (the design of the deformation holes 121 allows the clamping end to have a direction that moves towards or away from the axis of the clamping tube 12). The clamping end has a certain elastic deformation capability; a first contact surface 122 is provided on the outer side of the clamping end, and the first contact surface 122 extends obliquely from the clamping end to the control end, with the oblique direction being the axial direction of the clamping tube 12; a second contact surface 111 is provided on the inner side of the end of the sleeve 11 near the clamping end, and the extension direction of the second contact surface 111 is the same as the extension direction of the first contact surface 122. Thus, when 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 third driving member, causing the first contact surface 122 and the second contact surface 111 to be relatively displaced, 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 third driving member drives the clamping tube 12 to move towards the clamping end, and the clamping end gradually returns to its original position (the clamping end deforms away from the axis of the clamping tube 12), thereby releasing the clamping of the rotor end.

[0042] 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.

[0043] like Figure 3As 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, a motor, belt and pulley can be provided to drive the sleeve 11 to rotate, and a limiting structure is provided between the sleeve 11 and the clamping tube 12 to prevent relative rotation between the clamping tube 12 and the sleeve 11, 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, so that the clamping end is close to or away from the second mounting base 3. The limiters 22 at both ends of the linear track 21 limit and buffer the movement of the slide block 13.

[0044] like Figure 5 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.

[0045] Further optimization involves mounting the sleeve 11 on the slide block 13 via a bearing to reduce friction between the sleeve 11 and the slide block 13; and making the outer surface of the sleeve 11 near the clamping end tapered, thus reducing interference with the winding mechanism.

[0046] 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.
