Description

Technical Field

[0001] This utility model relates to the field of winding machine technology, and in particular to a CNC winding machine. Background Technology

[0002] In many industries such as electronics, electrical engineering, and machinery manufacturing, wire winding is a fundamental and crucial process, widely used in the production of products such as motors, transformers, inductors, and relays. The quality of the winding directly affects the performance, stability, and lifespan of the product.

[0003] The existing patent with publication number CN213935953U discloses a new type of CNC winding machine, whose structure includes a placement plate, a fixed box, a switch, a second fixed box, a power cord, a bracket, a motor, an output rod, a drum, a copper wire adjusting device, and auxiliary devices. The device features a copper wire adjustment mechanism mounted on the top surface of the second fixed box. When the operator starts the winding machine and rotates the drum, the drive wheel rotates simultaneously via the output rod, causing the transmission wheel to rotate along with the drive wheel via the transmission belt. The transmission wheel drives the rotating rod to rotate, causing the reciprocating screw to rotate simultaneously. The moving block slides along the surface of the reciprocating screw while rotating, and simultaneously slides along the surface of the fixed rod, causing the moving block to drive the support plate and the adjustment frame to move horizontally. As the drum winds the copper wire, the adjustment frame slides simultaneously, achieving the beneficial effect of horizontal adjustment of the copper wire during winding, resulting in better winding of the copper wire onto the surface of the drum.

[0004] Although the device has the aforementioned beneficial effects, in actual use, it is not convenient to disassemble and install the drum, which can easily affect the device's winding efficiency on the drum. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a CNC winding machine.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: This utility model discloses a CNC winding machine, comprising: The base has a fixing assembly inside, which includes a motor, a second motor, a two-way lead screw, a moving plate, a fixed plate, a fixed seat, and a guide rod. The top of the base has an installation groove and a guide groove. The first motor is installed on one side of the base. Two fixed plates are movably arranged on the top of the base. Two moving plates are installed on both sides of the bottom of the fixed plates. The two moving plates extend into the installation groove and the guide groove, respectively. A guide assembly is provided on one side of the top of the base.

[0007] As an optional technical solution of this utility model, the bidirectional lead screw is rotatably installed inside the mounting groove, the guide rod is fixedly installed inside the guide groove, and the rotating shaft of the motor extends into the interior of the mounting groove and is connected to one end of the bidirectional lead screw.

[0008] As an optional technical solution of this utility model, the movable plate on one side of the bottom of the two fixed plates is threadedly connected to the bidirectional lead screw, and the movable plate on the other side of the bottom of the two fixed plates is slidably connected to the guide rod.

[0009] As an optional technical solution of this utility model, the second motor is installed on the outer side of the fixing plate on one side, and the fixing seat is rotatably installed on the inner side of the fixing plates on both sides through bearings. The rotating shaft of the second motor is fixedly connected to the fixing seat on one side.

[0010] As an optional technical solution of this utility model, the guide assembly includes a motor, a support plate, a threaded rod, a limiting rod, a movable seat, a threading hole, a spring, a damping rod, a movable frame, and a guide roller. The support plate is installed on both sides of the top of the base, and the motor is installed on the outer side of one of the support plates. The threaded rod is rotatably installed on the opposite side of the support plate, and the limiting rod is fixedly installed below the threaded rod. One end of the movable seat is threadedly connected to the threaded rod, and the other end of the movable seat is slidably connected to the limiting rod.

[0011] As an optional technical solution of this utility model, a groove is provided on one side of the top of the movable seat. The top of the groove and the side near the fixed component are open. Four damping rods are fixedly installed on both sides of the inside of the groove. The damping rods are in pairs. A movable frame is fixedly installed on the free end of the damping rods in the same group. The guide roller is rotatably installed inside the movable frame.

[0012] As an optional technical solution of this utility model, the damping rod is externally covered with the spring, one end of the spring is fixedly connected to the groove, the other end of the spring is fixedly connected to the movable frame, and the wire hole is opened on the front side of the groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model uses a motor to drive a bidirectional lead screw to rotate, causing two fixed plates to move in opposite directions or back to back. This achieves automatic clamping, fixing, and releasing of winding workpieces of different sizes, eliminating the need for manual adjustment, greatly improving production efficiency and reducing labor intensity. The movable plate on one side of the bottom of the fixed plate is threadedly connected to the bidirectional lead screw, while the movable plate on the other side is slidably connected to the guide rod.

[0014] 2. This utility model allows the movable seat in the guide assembly to reciprocate linearly along the threaded rod under the drive of motor three. It can adjust the position of the guide roller in real time according to the changes in the winding position. At the same time, when the tension on the wire changes, the guide roller will push the movable frame to compress or stretch the spring and damping rod. The spring and damping rod work together to enable the guide roller to automatically adjust its position according to the tension of the wire, ensuring that the wire is always in a suitable tension state. This effectively avoids the problem of wire breaking due to excessive tension or loosening due to insufficient tension, improves the uniformity and tightness of winding, and thus improves the winding quality.

Detailed Implementation

[0016] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0017] In the attached diagram, all identical reference numerals refer to the same components.

[0018] like Figure 1-4 As shown, this utility model provides a CNC winding machine, comprising: The base 1 has a fixing component 2 inside. The fixing component 2 includes a motor 1 201, a motor 2 202, a two-way lead screw 203, a moving plate 204, a fixing plate 205, a fixing seat 206, and a guide rod 207. The top of the base 1 has an installation groove 3 and a guide groove 4. The motor 1 201 is installed on one side of the base 1. Two fixing plates 205 are movably installed on the top of the base 1. Two moving plates 204 are installed on both sides of the bottom of the fixing plates 205. The two moving plates 204 extend into the installation groove 3 and the guide groove 4, respectively. A guide component 5 is provided on one side of the top of the base 1.

[0019] Example 1 In this embodiment, a bidirectional lead screw 203 is rotatably mounted inside the mounting groove 3, a guide rod 207 is fixedly mounted inside the guide groove 4, and the rotating shaft of the motor extends into the mounting groove 3 and is connected to one end of the bidirectional lead screw 203.

[0020] Furthermore, the movable plate 204 on one side of the bottom of the two fixed plates 205 is threadedly connected to the bidirectional lead screw 203, and the movable plate 204 on the other side of the bottom of the two fixed plates 205 is slidably connected to the guide rod 207.

[0021] Furthermore, a motor 202 is installed on the outer side of one side fixing plate 205, and a fixing seat 206 is rotatably installed on the inner side of both sides fixing plates 205 via bearings. The rotating shaft of the motor 202 is fixedly connected to the fixing seat 206 on one side.

[0022] Specifically, the bidirectional lead screw 203 is driven to rotate by the motor 201, which in turn causes the two fixed plates 205 to move in opposite directions or away from each other, thereby enabling rapid clamping and release of winding workpieces of different sizes. The sliding cooperation between the guide rod 207 and the moving plate 204 ensures the stability and straightness of the fixed plate 205 during movement, avoids positional deviation, improves clamping accuracy and reliability, and adapts to the production needs of workpieces of various specifications.

[0023] The motor 202 drives the fixed base 206 on one side to rotate, and the bearing support structure drives the workpiece to rotate synchronously, providing stable power for winding. The overall structure is compact, the power transmission is direct, and the workpiece change efficiency and operation convenience are improved.

[0024] Example 2 In this embodiment, the guide assembly 5 includes a motor 501, a support plate 502, a threaded rod 503, a limiting rod 504, a movable seat 505, a wire hole 506, a spring 507, a damping rod 508, a movable frame 509, and a guide roller 5010. Support plates 502 are installed on both sides of the top of the base 1. A motor 501 is installed on the outer side of one support plate 502. A threaded rod 503 is rotatably installed on the opposite side of the support plate 502. A limiting rod 504 is fixedly installed below the threaded rod 503. One end of the movable seat 505 is threadedly connected to the threaded rod 503, and the other end of the movable seat 505 is slidably connected to the limiting rod 504.

[0025] Furthermore, a groove is provided on one side of the top of the movable seat 505. The top of the groove and the side near the fixed component 2 are open. Four damping rods 508 are fixedly installed on both sides of the inside of the groove. The damping rods 508 are in pairs. A movable frame 509 is fixedly installed on the free end of the damping rods 508 in the same group. A guide roller 5010 is rotatably installed inside the movable frame 509.

[0026] Furthermore, a spring 507 is provided on the outside of the damping rod 508. One end of the spring 507 is fixedly connected to the groove body, and the other end of the spring 507 is fixedly connected to the movable frame 509. A wire hole 506 is provided on the front side of the groove body.

[0027] Specifically, the guide assembly 5 employs a composite structure of spring 507 and damping rod 508 to support the guide roller 5010, which automatically adjusts its position according to changes in wire tension, thus buffering tension fluctuations in real time. This design effectively avoids problems such as wire breakage due to excessive tension or excessive looseness, ensuring constant tension during winding and improving the uniformity of wire arrangement and the tightness of the winding.

[0028] Motor 501 drives threaded rod 503 to control linear motion of moving seat 505. Combined with sliding constraint of limit rod 504, high-precision displacement control of guide assembly 5 is achieved. Threading hole 506 and guide roller 5010 work together to ensure smooth wire passage and accurate guidance to workpiece surface, reducing winding deviation and wire skipping.

[0029] Working principle: Working principle of fixed components: When motor 201 is started, its rotating shaft drives the bidirectional lead screw 203 to rotate within the mounting slot 3. Since the movable plates 204 on one side of the bottom of the two fixed plates 205 are threadedly connected to the bidirectional lead screw 203, during the rotation of the bidirectional lead screw 203, according to the principle of threaded transmission, these two movable plates 204 will move in opposite directions or away from each other along the bidirectional lead screw 203, thereby clamping and fixing or releasing the workpiece.

[0030] Meanwhile, the movable plate 204 on the other side of the bottom of the two fixed plates 205 is slidably connected to the guide rod 207 in the guide groove 4. The guide rod 207 guides and stabilizes the movement of the fixed plates 205, ensuring that the fixed plates 205 do not shift during movement. By rotating the motor 201 forward and backward, the two fixed plates 205 can be controlled to move closer or further apart, thereby adapting to winding workpieces of different sizes and achieving initial positioning and fixation of the winding workpieces.

[0031] After the winding workpiece is fixed between the two fixing plates 205, the motor 202 on the outer side of one fixing plate 205 is started. The rotating shaft of the motor 202 drives the fixing seat 206 fixedly connected to it to rotate. Since the fixing seats 206 are rotatably mounted on the inner side of both fixing plates 205 through bearings, and the winding workpiece is fixed between the two fixing seats 206, the rotation of the motor 202 will drive the winding workpiece to rotate together, providing rotational power for the winding operation.

[0032] Working principle of guide component 5: When motor 3 (501) is started, its rotating shaft drives the threaded rod 503 to rotate between the support plates 502. Because one end of the movable seat 505 is threadedly connected to the threaded rod 503 and the other end is slidably connected to the limit rod 504, the movable seat 505 will move linearly along the axial direction of the threaded rod 503 when the threaded rod 503 rotates, according to the principle of threaded transmission. By controlling the forward and reverse rotation of motor 3 (501), the reciprocating movement of the movable seat 505 on the threaded rod 503 can be achieved.

[0033] Within the groove on one side of the top of the movable seat 505, two sets of damping rods 508 are provided. A movable frame 509 is fixedly installed at the free end of each damping rod 508, and a guide roller 5010 is rotatably mounted inside the movable frame 509. A spring 507 is externally covered by the damping rod 508, with both ends of the spring 507 fixedly connected to the groove and the movable frame 509, respectively. During the winding process, if the tension on the wire changes as it passes the guide roller 5010, the guide roller 5010 will be subjected to the force of the wire, thereby pushing the movable frame 509 to compress or stretch the spring 507 and the damping rod 508. The spring 507 and the damping rod 508 work together to buffer and adjust, allowing the guide roller 5010 to automatically adjust its position according to the tension of the wire, ensuring that the wire is always under appropriate tension. This prevents the wire from breaking due to excessive tension or becoming loose due to insufficient tension, thereby improving the winding quality.

[0034] The function of the wire-passing hole: The wire-passing hole 506 opened on the front side of the groove is used for the wire to pass through, so that the wire can smoothly enter the guide component 5, and after being guided by the guide roller 5010, it can be accurately wound onto the rotating winding workpiece to complete the winding operation.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
