Description

Technical Field

[0001] The invention relates to a motor accessory, in particular to an internal and external winding integrated machine for a brushless motor. Background Art

[0002] The brushless motor consists of an electric motor body and a driver. It is a typical mechatronics product. Compared with a brushed motor, it does not have carbon brushes like a brushed motor, so it is called a brushless motor. It consists of a stator and a rotor. The stator is a fixed part, and the rotor is a rotating part. There are two types of brushless motors, one is an inner rotor and the other is an outer rotor. For example, a permanent magnet is attached to the rotor of a brushless motor, and the stator is a coil winding. The energized coil will generate a magnetic field, just like a magnet, with an N pole and an S pole. The magnet on the rotor will attract or repel the coil, so that the rotor will rotate. However, if the N pole and S pole of the magnetic field generated by the coil remain stationary, the rotor will eventually stop, just like two magnets sucked together, so the N pole and S pole of the coil on the stator need to be changed at all times, and the rotor will chase.

[0003] When producing the stator of a brushless motor, a winding operation is required, that is, the enameled wire is wound around the stator frame. In the actual winding operation, due to the different structures of the stator, two different methods of external winding or internal winding are required. When internal winding is required, an internal winding machine is required for winding, and when external winding is required, another external winding device (often a flying fork winding machine) is required. In this way, since two devices are required to wind different stators, the production cost is relatively high. Summary of the invention

[0004] The purpose of the present invention is to provide a brushless motor internal and external winding integrated machine.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: a brushless motor internal and external winding integrated machine, comprising a chassis and a workbench arranged on the chassis, wherein the workbench is provided with a stator fixing device and a winding device;

[0006] The stator fixing device comprises an inner fixing ring and an outer fixing ring, the inner fixing ring comprises a plurality of inner abutment plates arranged in a circumferential array, the outer fixing ring comprises a plurality of outer fixing plates arranged in a circumferential array, and the number of the inner abutment plates is the same as that of the outer fixing plates; the stator fixing device also comprises a horizontally arranged slide rail, the slide rail is arranged in a plurality of circumferential arrays, the inner abutment plates and the outer fixing plates are both provided with a base that cooperates with the slide rail to slide, the slide rail is provided with a first driving device that drives the inner abutment plate and the outer fixing plate to move along the slide rail, and the base is also provided with a second driving device for driving the inner abutment plate and the outer fixing plate to move longitudinally;

[0007] The winding device comprises a wire box and a winding connector, a winding head is extended from the winding connector, and a wire groove is also arranged on the winding connector; and a driver is also included for driving the winding connector to move longitudinally back and forth.

[0008] By adopting the above technical scheme, usually in the prior art, inner winding and outer winding are often completed by two machines and cannot be completed in the same machine equipment. Although the only few internal and external winding machines can realize inner winding or outer winding on one device, most of them are realized by disassembling the workstation or winding device. The winding device for the inner winding is removed, and then the winding device for the outer winding device is installed, so that both inner winding and outer winding can be achieved on the same device. However, such a setting is disassembled multiple times, which is not only easy to cause a high loss rate of the disassembly point, but also causes wear of the disassembly point after long-term disassembly, which may reduce the precision of the machine; in the present application, the wire box is arranged above the workbench, and the total coil is arranged in the wire box. In the process, the wire is wound out from the wire box and connected to the winding head, which can make repeated longitudinal movements after receiving the driving force; the stator fixing device is used to fix the stator to be wound. If the stator is of internal winding type, it means that the stator needs to be fixed on the outer wall of the stator, and then it is fixed with an external fixing ring, and the position of the external fixing plate is adjusted on the slide rail. As the external fixing plate slides on the slide rail, the diameter of the external fixing ring composed of several external fixing plates is different, so it can be adjusted according to the size of the stator; if the stator is of external winding type, it is fixed with an internal fixing ring in the same way; and the internal and external fixing rings can rotate on their axes, and then cooperate with the repeated longitudinal movements of the winding head to complete the winding action of the stator.

[0009] Preferably, the first driving device adopts a cylinder.

[0010] Preferably, the second driving device adopts a cylinder.

[0011] Preferably, the workbench is provided with a third driving mechanism for driving the inner fixed ring and the outer fixed ring to rotate around their axis.

[0012] Preferably, a plurality of inner fixing rings, outer fixing rings and winding devices are arranged in an array on the workbench.

[0013] By adopting the above technical solution, the inner fixed circle and the outer fixed circle are arranged in an array, which can enhance the winding efficiency and enable multiple stations to be carried out simultaneously.

[0014] Preferably, the workbench is further provided with a sliding groove, and the winding connector is provided with a sliding fixing device that slides in the sliding groove.

[0015] By adopting the above technical solution, the winding connector can slide in the sliding groove, so as to adjust the positional relationship between the winding connector and the stator, for example, the winding connector can be adjusted to the outside of the inner fixing ring and the outer fixing ring, or the winding connector can be adjusted to the inner fixing ring and the outer fixing ring.

[0016] Preferably, the winding connector includes a connecting rod and a cross rod arranged perpendicular to the connecting rod, and also includes a wire hook arranged at the end of the cross rod; the cross rod and the connecting rod are slidably arranged.

[0017] By adopting the above technical solution, the positional relationship between the cross bar and the connecting rod can be adjusted so that the cross bar and the connecting rod form a T shape, or an L shape; when it is an L shape, only one layer of the stator can be wound; when it is a T shape, the stators on both sides can be wound at the same time; two groups of inner and outer fixed rings can be symmetrically arranged on the workbench, and the winding device is arranged at the center axis of the two groups of fixed rings.

[0018] Preferably, the sliding fixing device comprises a guide block arranged on the winding connector, the guide block slides in the sliding groove, the sliding groove is a magnetic groove body, and the guide block is an electromagnet.

[0019] By adopting the above technical solution,

[0020] In summary, the present invention has the following beneficial effects:

[0021] 1. The wire box is set above the workbench, and the main coil is set in the wire box. The wire is wound out of the wire box and connected to the winding head. The winding head can make longitudinal repeated movements after receiving the driving force; the stator fixing device is used to fix the stator to be wound. If the stator is an internal winding type, it means that the stator needs to be fixed on the outer wall of the stator, and then it is fixed with an external fixing ring. The position of the external fixing plate is adjusted on the slide rail. As the external fixing plate slides on the slide rail, the diameter of the external fixing ring composed of several external fixing plates is different, so it can be adjusted according to the size of the stator; if the stator is an external winding type, it is fixed with an internal fixing ring in the same way; and the internal fixing ring and the external fixing ring can rotate on their axis, and then cooperate with the longitudinal repeated movement of the winding head to complete the winding action of the stator;

A plurality of inner fixing rings, outer fixing rings and winding devices are arranged in an array on the workbench; the inner fixing rings and outer fixing rings are arranged in an array to enhance the winding efficiency and enable multiple workstations to be operated simultaneously; two groups of inner and outer fixing rings can be symmetrically arranged on the workbench, and the winding devices are arranged at the center axes of the two groups of fixing rings; the positional relationship between the crossbar and the connecting rod is adjusted to form a T shape between the crossbar and the connecting rod, or to form an L shape between the crossbar and the connecting rod; when the L shape is formed, only one layer of the stator can be wound; when the T shape is formed, the stators on both sides can be wound at the same time.

After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.

[0031] Example:

[0032] A brushless motor internal and external winding integrated machine, such as Figure 1 , 3 As shown, it includes a chassis 1 and a workbench 2 arranged on the chassis 1, and the workbench 2 is provided with a stator fixing device and a winding device.

[0033] like Figure 2 , 3As shown in Figure 4, the stator fixing device includes an inner fixing ring 31 and an outer fixing ring 32. The inner fixing ring 31 includes a plurality of inner abutting plates 311 arranged in a circumferential array, and the outer fixing ring 32 includes a plurality of outer fixing plates 321 arranged in a circumferential array. The number of the inner abutting plates 311 and the outer fixing plates 321 is the same; the stator fixing device also includes a horizontally arranged slide rail 33. The slide rail 33 is arranged in a circumferential array. The inner abutting plates 311 and the outer fixing plates 321 are both provided with a base 34 that cooperates with the slide rail 33 to slide. The slide rail 33 is provided with a first driving device that drives the inner abutting plates 311 and the outer fixing plates 321 to move along the slide rail 33. The base 34 is also provided with a second driving device for driving the inner abutting plates 311 and the outer fixing plates 321 to move longitudinally.

[0034] like Figure 1 , 5 As shown, the winding device includes a wire box 41 and a winding connector 42, a winding head 43 is extended from the winding connector 42, and a wire groove 421 is also provided on the winding connector 42; it also includes a driver for driving the winding connector 42 to reciprocate longitudinally, and the driver can be a cylinder.

[0035] like Figure 3 , 4 As shown, the first driving device adopts a cylinder, and two groups of the first driving device can be provided on each group of slide rails 33, respectively used to drive the inner abutment plate and the outer fixing plate; the second driving device adopts a cylinder.

[0036] like Figure 1 , 2 As shown in Figure 3, the workbench 2 is provided with a third driving mechanism for driving the inner fixing ring 31 and the outer fixing ring 32 to rotate around their axis. The third driving mechanism can adopt a motor, and the motor can be connected to only one of the inner abutment plates 311 or the outer fixing plate 321. Because at this time the inner abutment plate 311 and the outer fixing plate 321 have been abutted on the stator to temporarily form a whole, so as long as they are connected to one of the inner fixing plates or the outer fixing plates, the driving of the overall movement can be realized.

[0037] like Figure 1 , 2 As shown in FIG. 3 , a plurality of inner fixing rings 31 , outer fixing rings 32 and winding devices are arranged in an array on the workbench 2 ; a round table is detachably arranged on the workbench 2 , on which the inner fixing rings 31 , outer fixing rings 32 are arranged, and a slide rail 33 is also arranged.

[0038] like Figure 1 , 5As shown, a sliding groove 21 is also provided on the workbench 2, and a sliding fixing device that slides in the sliding groove 21 is provided on the winding connector 42. The round table and the sliding groove 21 are not conflictingly arranged, and the round table is embedded in the workbench 1. The depth of the sliding groove 21 is deeper than the embedding depth of the round table. When sliding is required, the round table can be removed, slid to a suitable position, and then installed.

[0039] like Figure 1 , 5 As shown, the winding connector 42 includes a connecting rod 422 and a cross rod 423 vertically arranged with the connecting rod 422, and the winding head 43 is arranged at the end of the cross rod 423; the cross rod 423 and the connecting rod 422 are slidably arranged, and the wire hook can be arranged at both ends or only at one end.

[0041] Working principle:

[0042] The wire box is arranged above the workbench, and the main coil is arranged in the wire box. The wire is wound out of the wire box and connected to the winding head. The winding head can make repeated longitudinal movements after receiving the driving force. The stator fixing device is used to fix the stator to be wound. If the stator is of internal winding type, it means that the stator needs to be fixed on the outer wall of the stator, and then it is fixed with an external fixing ring, and the position of the external fixing plate is adjusted on the slide rail. When the external fixing plate slides on the slide rail, the diameter of the external fixing ring composed of several external fixing plates is different, so it can be adjusted according to the size of the stator. If the stator is of external winding type, it is fixed with an internal fixing ring in the same way. The internal fixing ring and the external fixing ring can rotate on their axes, and then cooperate with the repeated longitudinal movements of the winding head to complete the winding action of the stator.
