Description

Technical Field

[0001] This utility model specifically relates to the field of resolver wiring technology, and more specifically to an automatic wiring mechanism for resolver production lines. Background Technology

[0002] The automatic wire laying mechanism for a resolver production line is a guiding mechanism used in resolver production equipment. It is generally used in conjunction with an automatic winding mechanism. The enameled wire first passes through the automatic wire laying mechanism and then enters the automatic winding mechanism. The automatic wire laying mechanism is driven by a servo motor or stepper motor to wind the enameled wire into the stator. The automatic wire laying mechanism can ensure the accuracy and uniformity of the enameled wire laying, thereby improving the electrical performance and reliability of the resolver.

[0003] However, in practice, it has been noted that while the winding mechanism can tension the enameled wire during use to ensure the tightness of the wound wire, during high-speed winding, the degree of deformation caused by the downward pressure varies due to the different inclination angles of the spring rods. The copper wire inside the enameled wire is generally quite soft, and when the degree of bending is large, the tension is large, which can easily cause the copper wire inside to extend in length, affecting the winding quality and thus affecting the normal use of the resolver. Utility Model Content

[0004] The purpose of this invention is to provide an automatic wire laying mechanism for a resolver production line. Through the rotational engagement between the shaft sleeve and the mounting shaft, the tilt angle of the elastic metallic sheath can be adjusted, thereby adjusting the maximum bending degree of the elastic metallic sheath and consequently adjusting the tension during enameled wire laying. This solves the technical problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automatic winding mechanism for a rotary transformer production line includes a rotary transformer winding machine base, a winding machine protective cover fixedly connected above the rotary transformer winding machine base, and a horizontal support rod fixedly connected to the top of the winding machine protective cover.

[0007] A cable laying mechanism is fixedly connected in a rectangular array on the horizontal support rod. Each group of cable laying mechanisms includes two symmetrically arranged wire laying devices. A tensioning extension rod is movably connected to the side of the wire laying device, and the end of the tensioning extension rod away from the wire laying device is fixedly connected to a guide wheel frame.

[0008] As a further technical solution of this utility model, the wire guide includes a guide housing, and two interlocking groove guide frames are movably connected to the side of the guide housing. The groove guide frames are provided with a mounting shaft fixedly connected to the guide housing.

[0009] As a further technical solution of this utility model, the tensioning extension rod includes a shaft sleeve that rotatably engages with the mounting shaft, and an inclined elastic metal part is fixedly connected to the side of the mounting shaft, and a guide wheel frame is fixedly connected to the side of the elastic metal part away from the shaft sleeve.

[0010] As a further technical solution of this utility model, the side of the shaft sleeve away from the elastic metallic feel is integrally provided with a triangular extension plate, and a spiral positioning knob is threadedly connected in the triangular extension plate, and the end of the spiral positioning knob passes through the triangular extension plate.

[0011] As a further technical solution of this utility model, the guide housing is provided with a positioning groove arranged in a ring array with the mounting shaft as the axis on the side near the shaft sleeve, and the end of the spiral positioning knob is inserted into the positioning groove.

[0012] As a further technical solution of this utility model, the bottom of the guide shell is fixedly connected with a mounting clamp plate, and the mounting clamp plate is sleeved on the outside of the transverse support rod, and a fastener is threadedly connected between the transverse support rod and the mounting clamp plate.

[0013] As a further technical solution of this utility model, a rotary transformer fixing seat is also installed on the rotary transformer winding machine base, and a transformer winding component is provided above the rotary transformer fixing seat.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, the enameled wire first passes through the inner side of the grooved guide frame, then passes over the top of the guide wheel frame and is introduced downward into the transformer winding component. Due to the elasticity of the elastic metal itself, when the enameled wire moves downward, the end of the elastic metal near the guide wheel frame will bend after being pulled downward. The reaction force of the elastic metal can tension the enameled wire, ensuring the tension of the enameled wire during the production line process.

[0016] This invention, based on the required tension force during the winding of enameled wire, involves rotating the shaft sleeve to cause the elastic metal element to rotate on the outside of the mounting shaft, thereby adjusting the maximum bending degree of the elastic metal element and thus individually adjusting the tension of each enameled wire.

[0017] This invention involves rotating a spiral positioning knob. Through the threaded engagement between the spiral positioning knob and the shaft sleeve, the end of the spiral positioning knob is inserted into a grooved guide frame at a suitable position. Multiple grooved guide frames are arranged in a circular array around the mounting shaft, thereby locking the position of the elastic metal and the shaft sleeve and preventing the shaft sleeve from sliding under force.

Detailed Implementation

[0025] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 This utility model embodiment provides an automatic winding mechanism for a rotary transformer production line, including a rotary transformer winding machine base 1, a winding machine protective cover 2 fixedly connected above the rotary transformer winding machine base 1, and a horizontal support rod 5 fixedly connected to the top of the winding machine protective cover 2.

[0027] A cable laying mechanism is fixedly connected in a rectangular array on the transverse support rod 5. Each group of cable laying mechanisms includes two symmetrically arranged wire laying devices 6, and a tensioning extension rod 7 is movably connected to the side of the wire laying device 6. The end of the tensioning extension rod 7 away from the wire laying device 6 is also fixedly connected to a guide wheel frame 8.

[0028] Furthermore, the wire guide 6 includes a guide housing 61, and two interlocking groove guide frames 64 are movably connected to the side of the guide housing 61. A mounting shaft 63 fixedly connected to the guide housing 61 is provided above the groove guide frames 64.

[0029] Furthermore, the tensioning extension rod 7 includes a shaft sleeve 72 that rotatably engages with the mounting shaft 63, and an inclined elastic metal element 71 is fixedly connected to the side of the mounting shaft 63, and the guide wheel frame 8 is fixedly connected to the side of the elastic metal element 71 away from the shaft sleeve 72.

[0030] By adopting the above technical solution, rotating the spiral positioning knob 73, through the threaded engagement between the spiral positioning knob 73 and the shaft sleeve 72, allows the end of the spiral positioning knob 73 to be inserted into the grooved guide bracket 64 at a suitable position. Multiple grooved guide brackets 64 are arranged in a ring array with the mounting shaft 63 as the axis, thereby locking the position of the elastic metal 71 and the shaft sleeve 72 and preventing the shaft sleeve 72 from sliding under force.

[0031] More specifically, the shaft sleeve 72 is integrally provided with a triangular extension plate on the side away from the elastic metallic feel 71, and a spiral positioning knob 73 is threadedly connected to the triangular extension plate, and the end of the spiral positioning knob 73 passes through the triangular extension plate.

[0032] By adopting the above technical solution, the enameled wire first passes through the inner side of the groove guide frame 64, then passes over the top of the guide wheel frame 8 and is introduced downward into the transformer winding component 4. Due to the elasticity of the elastic metal sensor 71 itself, when the enameled wire moves downward, the end of the elastic metal sensor 71 near the guide wheel frame 8 will bend after being pulled downward. The reaction force of the elastic metal sensor 71 can tension the enameled wire, ensuring the tension of the enameled wire during the production line process.

[0033] Furthermore, the guide housing 61 has a positioning groove 62 arranged in a ring array with the mounting shaft 63 as the axis on the side near the shaft sleeve 72, and the end of the spiral positioning knob 73 is inserted into the positioning groove 62.

[0034] Furthermore, the bottom of the guide housing 61 is fixedly connected to a mounting clamp 9, and the mounting clamp 9 is sleeved on the outside of the transverse support rod 5, and a fastener is threadedly connected between the transverse support rod 5 and the mounting clamp 9.

[0035] Furthermore, a rotary transformer fixing seat 3 is also installed on the rotary transformer winding machine base 1, and a transformer winding component 4 is provided above the rotary transformer fixing seat 3.

[0036] By adopting the above technical solution, according to the required tension force during the winding of enameled wire, the shaft sleeve 72 is rotated, causing the shaft sleeve 72 to drive the elastic metal element 71 to rotate on the outside of the mounting shaft 63, thereby adjusting the maximum bending degree of the elastic metal element 71, and thus adjusting the tension of each enameled wire individually.

[0037] The inner side of the guide wheel frame 8 is movably connected to a guide concave wheel, and the outer side of the guide wheel frame 8 is provided with interlaced wire baffles, which are fixedly connected to the guide wheel frame 8. The enameled wire is passed through the interlaced wire baffles and around the top of the guide concave wheel to prevent the enameled wire from separating from the guide concave wheel, thereby improving the wiring effect.

[0038] The working principle of this utility model is as follows: In use, the enameled wire is first introduced from the rear. The end of the enameled wire passes through two interlocking grooved guide frames 64, and then passes over the top of the guide wheel frame 8 before being introduced downwards into the transformer winding component 4. When the transformer winding component 4 is working, the enameled wire is pulled inwards by a traction force. At this time, the guide wheel frame 8 is subjected to a downward pulling force, which applies a downward pulling force to the end of the elastic metal element 71, causing the end of the elastic metal element 71 to deform downwards. The reaction force generated after the elastic metal element 71 deforms will tension the enameled wire, thereby ensuring the tightness of the enameled wire during winding. The enameled wire is relatively fragile. Rotating the shaft sleeve 72 causes the elastic metal element 71 to rotate around the mounting shaft 63, thus adjusting the tilt angle of the elastic metal element 71 and changing its maximum bending degree. Then, rotating the spiral positioning knob 73, through the threaded engagement between the knob and the shaft sleeve 72, allows the end of the knob to insert into the grooved guide bracket 64 at a suitable position, thereby adjusting the tension during the enameled wire winding process. This prevents deformation or breakage of the enameled wire due to excessive tension during winding. The structure is simple, the operation is very convenient, and it effectively reduces manual labor intensity.
