Description

Technical Field

[0001] The utility model relates to the technical field of winding machines, and more specifically, to a turnover mechanism of a numerically controlled winding machine used for processing inductor coils. Background Art

[0002] At present, in various circuit systems, inductors play an extremely important role and have been widely used. There is an inductor on the market (see butterfly inductor Figure 1 ) is composed of a pair of coils wound around a magnetic ring one circle at a time, and four pins (i.e. PIN pins) are led out after a certain number of turns. At the same time, in order to increase the inductance, an iron core or a magnetic powder core is usually set in the inner cavity of the magnetic ring. This type of inductor coil is divided into three categories according to its appearance, namely, an inductor coil without a base and a bottom plate, an inductor coil with a bottom plate, and an inductor coil with a base.

[0003] The winding machine is a device that winds a linear object onto a specific workpiece. It can be used to wind the above-mentioned inductor coil, and the wire nozzle is one of the important parts for conveying and winding the wire. The winding machine now mostly uses a wire nozzle flipping mechanism to complete the flipping of the wire nozzle. In actual use, it has the advantages of simple operation, convenient installation and long service life.

[0004] In the prior art, for example, the utility model patent with patent publication number CN206232217U discloses a novel nozzle flipping mechanism for a winding machine, which comprises: a driving mechanism with a driving part that can move up and down, a fixed rod, a rotating part with a nozzle, a connecting rod and a connecting part, wherein the connecting part is fixedly connected to the driving part of the driving mechanism, one end of the connecting rod is hinged to the connecting part, and the other end is hinged to the rotating part; the rotating part is hinged to the fixed rod.

[0005] In the above-mentioned prior art, although only the nozzle is flipped, no large flipping space is required, the space occupied is small, the driving mechanism structure is simple, the efficiency is high, the load is small and the energy consumption is low, but there are still the following defects:

[0006] First, the turning process of the nozzle is realized by pushing and pulling the connecting rod. During the pushing process of the connecting rod, the connecting rod tends to support outward, so that after the nozzle is turned over, the range supported by the connecting rod is larger than the size of the nozzle, so that the turning space is still adjusted later, so as to reduce the turning space and be suitable for the processing of smaller inductor coils;

[0007] Secondly, the connecting rod is subjected to large forces. In order to avoid deformation of the connecting rod, the material used for the connecting rod needs to be of high quality, otherwise it is easy to be damaged, resulting in deviation of the flipping angle;

[0008] Therefore, in view of the above defects, a CNC winding machine flipping mechanism for inductor coil processing is proposed. Utility Model Content

[0009] In order to overcome the above-mentioned defects of the prior art, the utility model provides a flipping mechanism of a CNC winding machine for processing an inductor coil, so as to solve the problems raised in the above-mentioned background technology.

[0010] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a flipping mechanism of a CNC winding machine for inductor coil processing, comprising a fixed frame, a support frame bolted to one side of the fixed frame, a guide cylinder installed at the bottom end of the support frame, a cylinder supported on the support frame, the cylinder is provided with a piston rod, a connecting assembly is installed at the bottom end of the piston rod, a limiting nut is installed at the top end of the piston rod, a flipping piece is movably connected to the bottom end of the guide cylinder, a support rod is movably connected between the flipping piece and the connecting assembly, a roller is installed at one end of the flipping piece, and a wire nozzle is provided at the other end of the flipping piece.

[0011] Through the operation of the cylinder, the piston rod pushes and pulls the connecting assembly that is slidably connected to the guide cylinder. When the connecting assembly is pushed down, the thread nozzle is flipped from a parallel state to the guide cylinder to a perpendicular state to the guide cylinder. The support rod is pressed down. Since the support rod is in an inclined state when the thread nozzle is perpendicular to the guide cylinder, the support rod can easily press down one end of the flipping member. When one end of the flipping member is rotatably connected to the bottom of the guide cylinder, the flipping member is tilted. Therefore, under the limitation of the limit nut, when the piston rod stroke is limited, the flipping member is perpendicular to the guide cylinder, so that the thread nozzle is in a perpendicular state to the guide cylinder, thereby realizing the vertical flipping of the thread nozzle.

[0012] When the connection assembly is pulled up so that the wire nozzle is flipped from a vertical state with the guide cylinder to a parallel state with the guide cylinder, the connection assembly slides up along the guide cylinder and pulls up the inclined support rod so that the support rod pulls the flipping member, so that the connection between the support rod and the flipping member enters the guide cylinder through the sliding groove, and the flipping member is parallelly attached to the guide cylinder, so that the wire nozzle and the guide cylinder are in a parallel state, thereby realizing the parallel flipping of the wire nozzle;

[0013] During the flipping process of the wire nozzle, since the support rod is always in an inclined state, the force on the support rod is only to share the gravity of the flipping part, so that the force on the support rod is relatively small and it is not easy to deform and wear, thereby reducing the material requirements for the support rod, thereby increasing the service life of the support rod, making the overall life longer and requiring less frequent maintenance. In this way, the manufacturing cost and maintenance cost of the flipping mechanism are reduced, and during the flipping process back and forth, the flipping range is within the size range of the flipping part, and no additional protrusions are generated, thereby reducing the flipping space, so that the winding machine can be set according to the size of the flipping part to adapt to the processing of smaller inductor coils.

[0014] Preferably, a slide groove is provided on one side of the guide cylinder, and a second connecting frame is welded to the middle of the bottom end of the guide cylinder.

[0015] Preferably, the connecting assembly comprises a connecting sleeve, which is screwed to the bottom end of the piston rod and is slidably matched with the inner wall of the guide cylinder;

[0016] A push-pull frame, which is welded to one side of the middle part of the bottom end of the connecting sleeve;

[0017] A screw hole is provided on the connecting sleeve.

[0018] Preferably, a thread is provided at the bottom end of the piston rod, and a thread hole is provided at the threaded position, the thread hole is connected and matched with the screw hole, and a top screw is connected between the thread hole and the screw hole.

[0019] Preferably, a first connecting frame movably connected to the support rod is welded on the flip member, the width of the first connecting frame is smaller than the width of the slide groove, and one end of the support rod is rotatably connected to the push-pull frame.

[0020] Preferably, a connecting block movably connected to the second connecting frame is welded on the flip member, and the distance between the axis of the connecting block and the flip member is the same as the radius of the guide cylinder.

[0021] Preferably, a wire hole is provided on the flip member on one side of the roller, and the wire hole is connected to the wire nozzle.

[0022] Technical effects and advantages of the utility model:

[0023] 1. Through the arrangement of the guide cylinder, the slide groove, the first connecting frame, the support rod, the connecting assembly, the second connecting frame and the connecting block, a slide groove with a size larger than that of the first connecting frame is opened on one side of the guide cylinder, so that when the push-pull frame pulls up the support rod, the support rod pulls the first connecting frame. During the pulling process, the support rod becomes smaller with the rise of the push-pull frame due to the movable connection at both ends. Because the push-pull frame is welded to one side of the middle part of the bottom end of the connecting sleeve, when the first connecting frame is vertically inserted into the slide groove, the support rod is stored in the guide cylinder, and when the support rod is pressed down, the first connecting frame connected to the end of the support rod is always on the inner side of the top of the flip part, so that during the back and forth flipping process, the flipping range is within the size range of the flip part, and no additional protrusion is generated, thereby reducing the flipping space, so that the winding machine can be adapted to the processing of smaller inductor coils according to the size setting of the flip part.

[0024] 2. At the same time, through the above structure, during the flipping process of the wire nozzle, because the support rod is always in an inclined state, the force on the support rod is only to share the gravity of the flipping part, so that the force on the support rod is relatively small, and it is not easy to deform and wear, thereby reducing the material requirements for the support rod, thereby increasing the service life of the support rod, making the overall life longer, and not requiring frequent maintenance, thereby reducing maintenance costs and improving the stability of the winding machine operation.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] As attached Figure 1-5 The flipping mechanism of a CNC winding machine for processing an inductor coil shown in the figure comprises a fixed frame 1, a support frame 2 is bolted to one side of the fixed frame 1, a guide cylinder 3 is installed at the bottom end of the support frame 2, a cylinder 4 is supported on the support frame 2, and the cylinder 4 is provided with a piston rod 5, a connecting assembly 7 is installed at the bottom end of the piston rod 5, a limiting nut 6 is installed at the top end of the piston rod 5, a flipping piece 8 is movably connected to the bottom end of the guide cylinder 3, a support rod 9 is movably connected between the flipping piece 8 and the connecting assembly 7, a roller 12 is installed at one end of the flipping piece 8, and a wire nozzle 13 is arranged at the other end of the flipping piece 8, a wire hole for threading is opened on the flipping piece 8 on one side of the roller 12, and the inductor wire is guided into the wire hole through the roller 12 and passes out from the wire nozzle 13.

[0033] During specific implementation, through the operation of the air cylinder 4, the piston rod 5 pushes and pulls the connecting assembly 7 that is slidably connected to the guide cylinder 3. When the connecting assembly 7 is pushed down, the thread nozzle 13 is flipped from a parallel state to the guide cylinder 3 to a perpendicular state to the guide cylinder 3. The support rod 9 is pressed down. Since the support rod 9 is in an inclined state when the thread nozzle 13 is perpendicular to the guide cylinder 3, the support rod 9 can easily press down one end of the flipping member 8. When one end of the flipping member 8 is rotatably connected to the bottom of the guide cylinder 3, the flipping member 8 is tilted. Therefore, under the limitation of the limit nut 6, when the stroke of the piston rod 5 is limited, the flipping member 8 is perpendicular to the guide cylinder 3, so that the thread nozzle 13 is in a perpendicular state to the guide cylinder 3, and the vertical flipping of the thread nozzle 13 is realized.

[0034] When the connection assembly 7 is pulled up, so that the nozzle 13 is flipped from a vertical state with the guide cylinder 3 to a parallel state with the guide cylinder 3, the connection assembly 7 slides up along the guide cylinder 3, and the inclined support rod 9 is pulled up, so that the support rod 9 pulls the flipping member 8, so that the connection between the support rod 9 and the flipping member 8 enters the guide cylinder 3 through the slide groove, and the flipping member 8 is parallel to the guide cylinder 3, so that the nozzle 13 is parallel to the guide cylinder 3, thereby realizing the parallel flipping of the nozzle 13;

[0035] During the flipping process of the wire mouth 13, since the support rod 9 is always in an inclined state, the force on the support rod 9 is only to share the gravity of the flipping part 8, so that the support rod 9 is subjected to less force and is not easy to deform and wear, thereby reducing the material requirements for the support rod 9, thereby increasing the service life of the support rod 9, making the overall life longer and requiring less frequent maintenance, thereby reducing the cost of the flipping mechanism and the maintenance cost, and during the flipping back and forth process, the flipping range is within the size range of the flipping part 8, and no additional protrusions are generated, thereby reducing the flipping space, so that the winding machine can be set according to the size of the flipping part 8 and adapt to the processing of smaller inductor coils.

[0036] As attached Figure 4 and Figure 5 As shown, a slide groove is opened on one side of the guide cylinder 3, a second connecting frame 14 is welded to the middle part of the bottom end of the guide cylinder 3, a first connecting frame 10 movably connected to the support rod 9 is welded to the flip member 8, the width dimension of the first connecting frame 10 is smaller than the width dimension of the slide groove, and one end of the support rod 9 is rotatably connected to the push-pull frame 702, a connecting block 11 movably connected to the second connecting frame 14 is welded to the flip member 8, and the distance dimension of the axis center of the connecting block 11 from the flip member 8 is the same as the radius dimension of the guide cylinder 3.

[0037] In the specific implementation, a slide groove with a size larger than that of the first connecting frame 10 is opened on one side of the guide cylinder 3, so that when the push-pull frame 702 pulls up the support rod 9, the support rod 9 pulls the first connecting frame 10. In the pulling process, the support rod 9 has a movably connected connection at both ends, and the angle between it and the guide cylinder 3 becomes smaller as the push-pull frame 702 rises. Since the push-pull frame 702 is welded to one side of the middle part of the bottom end of the connecting sleeve 701, when the first connecting frame 10 is vertically inserted into the slide groove, the support rod 9 is still in an inclined state, and the flipping of the wire nozzle 13 is completed. After the flipping is completed, the distance dimension of the axis center of the connecting block 11 from the flipping member 8 is the same as the radius dimension of the guide cylinder 3, so that the flipping member 8 fits on the guide cylinder 3, and the wire nozzle 13 is parallel to the guide cylinder 3.

[0038] As attached Figure 3 As shown, the connecting assembly 7 includes a connecting sleeve 701, which is screwed to the bottom end of the piston rod 5, and the connecting sleeve 701 is slidably matched with the inner wall of the guide cylinder 3;

[0039] A push-pull frame 702, wherein the push-pull frame 702 is welded to one side of the middle portion of the bottom end of the connecting sleeve 701;

[0040] The screw hole 703 is provided on the connecting sleeve 701 .

[0041] The bottom end of the piston rod 5 is provided with a thread, and a thread hole is provided at the threaded position, the thread hole is connected and matched with the screw hole 703, and a top screw is connected in the thread hole and the screw hole 703.

[0042] During specific implementation, the connecting sleeve 701 is screwed onto the bottom end of the piston rod 5, and the rotation of the connecting sleeve 701 is limited by the top screw, thereby improving the connection fixity between the connecting sleeve 701 and the piston rod 5 to avoid the connection sleeve 701 from slipping when force is generated between the push-pull frame 702 and the support rod 9. At the same time, with this installation structure, when the winding machine works for a long time and the axial hole or axial rod connecting the push-pull frame 702 and the support rod 9 is worn due to force and needs to be replaced, the connection between the connecting block 11 and the second connecting frame 14 can be disassembled, and the position of the limit nut 6 can be adjusted so that the piston rod 5 can be pushed out from the guide cylinder 3, and the connecting assembly 7 or the support rod 9 can be disassembled for later maintenance.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
