Description

Technical Field

[0001] The utility model relates to the technical field of magnetic core manufacturing equipment, in particular to a separate chuck module of a coil winding machine. Background Art

[0002] Coil winding machines are automated equipment used to produce various precision coils and are widely used in the manufacture of electronic components. The chuck, a key component of the winding machine, is responsible for precisely securing and guiding the wire to ensure stability and accuracy during the winding process. The trend toward miniaturization in modern electronic products has led to increasingly smaller coil cores, placing extremely high demands on the precision of the winding chuck's installation.

[0003] In traditional coil winding machines, the chuck is usually fixed to the frame through an integral mounting base. This design has the following technical problems:

[0004] The accuracy of the chuck's installation depends entirely on the machining accuracy of the mounting base itself and the precision control during the installation process. The mounting base must meet extremely high precision standards, which often leads to complex and costly manufacturing processes. The mounting base not only secures the chuck but also supports other transmission components (such as the drive shaft), making its design extremely complex. This complex design increases the difficulty of manufacturing and further drives up costs. For these reasons, the processing cost of an integral mounting base is generally very high, which is a significant factor restricting the overall cost of the winding machine. Utility Model Content

[0005] The purpose of the present utility model is to provide a separate chuck module for a coil winding machine. By adopting a separate mounting seat, the position of the chuck can be fine-tuned, and the processing and installation accuracy requirements of the mounting seat are relatively low; and the separate mounting seat structure reduces the volume of a single mounting seat component, further reducing the processing difficulty of the mounting seat, and achieving higher chuck installation accuracy at an overall lower processing cost.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0007] A separate chuck module for a coil winding machine includes a mounting base, a transmission mechanism, a chuck mechanism, and a chuck leveling mechanism. The transmission mechanism, the chuck mechanism, and the chuck leveling mechanism are mounted on the mounting base.

[0008] The mounting seat includes a base and an adjusting portion installed on the base, the chuck mechanism is installed on the adjusting portion, the chuck leveling mechanism is installed on the base, the transmission mechanism includes a transmission shaft 1 installed on the base and a transmission shaft 2 installed on the adjusting portion, and the transmission shaft 1 and the transmission shaft 2 are connected by a flexible transmission; the chuck mechanism is installed on the mounting seat through the transmission shaft 2.

[0009] Furthermore: the mounting surfaces of the base and the adjusting portion are concave-convex matching surfaces, wherein the mounting surface of the base is a concave surface, the mounting surface of the adjusting portion is a convex surface, and the profile size of the convex surface is smaller than the profile size of the concave surface.

[0010] Furthermore: the chuck leveling mechanism includes a chuck seat fixedly mounted on the second transmission shaft and an adjusting sleeve mounted on the base; the installation direction of the adjusting sleeve is parallel to the second transmission shaft and is located directly below the second transmission shaft; a V-shaped positioning groove is opened under the chuck seat, and the adjusting sleeve is tightly pressed in the V-shaped positioning groove.

[0011] Furthermore: the chuck leveling mechanism also includes a bracket installed on the base, the adjusting sleeve is installed on the base through the bracket, and a support is provided on the bracket, and the adjusting sleeve is rotatably installed on the support.

[0012] Furthermore: the adjusting sleeve includes a mounting shaft and a sleeve sleeved on the mounting shaft, one end surface of the mounting shaft is pressed against the support, and a limit pin is provided at the other end surface.

[0013] Furthermore: the material of the shaft sleeve is nylon.

[0014] Furthermore: the clamp leveling mechanism also includes a connecting plate, and the connecting plate is slidably mounted on the base through a vertical guide rail mechanism.

[0015] Furthermore: a compression spring is provided between the connecting plate and the base, and the compression spring has the same direction as the slide rail in the guide rail mechanism, the upper end of the compression spring presses against the connecting plate, and the lower end of the compression spring presses against the base.

[0016] Furthermore: the transmission shaft 1 and the transmission shaft 2 are connected via a synchronous belt transmission, and the transmission mechanism also includes a tensioning wheel installed on the synchronous belt.

[0017] Furthermore: a clutch is provided on one end of the transmission shaft connected to the power source, and a polyurethane docking block is installed on the clutch.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] First, this device utilizes a separate mounting base design, combining a base and an adjustment unit, to precisely adjust the chuck position. This ensures high chuck installation accuracy even under low machining and installation precision conditions. This fine-tuning capability improves the winding machine's operating accuracy and solves the problem of high chuck installation precision but complex overall structure.

[0020] Second, the separate mounting base structure simplifies the size and complexity of individual components, reduces processing difficulty, and thus reduces processing costs. Furthermore, since the machining and installation precision requirements for the mounting base are lower, this further reduces manufacturing costs and solves the problem of complex structure and high processing costs of the integral chuck device.

[0021] Third, the chuck leveling mechanism uses two threaded adjustment bolts to adjust the flatness of the chuck plate. However, these bolts have low adjustment precision, are easily worn, and require frequent maintenance. This device uses a wear-resistant adjustment sleeve that is tightly pressed into a V-shaped positioning groove. This not only makes the leveling of the chuck plate more convenient and quick, but also improves the wear resistance of the structure and extends the maintenance cycle. This simple, low-cost, and more wear-resistant design solves the problems of low adjustment precision and easy wear of the original adjustment structure.

[0022] Fourth, the flexible transmission connection between drive shafts 1 and 2 (e.g., synchronous belt drive) and the use of a tensioner effectively reduce chuck vibration, improving stability during the winding process and ensuring winding accuracy. Furthermore, the clutch design with a polyurethane docking block provides excellent shock absorption, resolving the issue of the original clutch's poor shock absorption and the resulting chuck vibration.

[0032] like Figure 1 The figure shows a separate chuck module for a coil winding machine, comprising a mounting base, a transmission mechanism 5, a chuck mechanism 3, and a chuck leveling mechanism 4. The transmission mechanism 5, chuck mechanism 3, and chuck leveling mechanism 4 are mounted on the mounting base. The mounting base comprises a base 1 and an adjustment portion 2 mounted on the base 1. The chuck mechanism 3 is mounted on the adjustment portion 2, and the chuck leveling mechanism 4 is mounted on the base 1. The transmission mechanism comprises a transmission shaft 1 5.1 mounted on the base 1 and a transmission shaft 2 5.2 mounted on the adjustment portion 2, with the transmission shaft 1 5.1 and the transmission shaft 2 5.2 being connected via a flexible transmission. The chuck mechanism 3 is mounted on the mounting base via the transmission shaft 2 5.2. The mounting surfaces of the base 1 and the adjustment portion 2 are concave-convex mating surfaces, wherein the mounting surface of the base 1 is concave and the mounting surface of the adjustment portion 2 is convex, and the profile dimensions of the convex surface are smaller than those of the concave surface.

[0033] The chuck leveling mechanism 4 includes a chuck seat 4.1 fixedly mounted on the second transmission shaft 5.2 and an adjustment sleeve 4.2 mounted on the base 1. The adjustment sleeve 4.2 is installed parallel to the second transmission shaft 5.2 and is located directly below the second transmission shaft 5.2. A V-shaped positioning groove is defined below the chuck seat 4.1, and the adjustment sleeve 4.2 is tightened in the V-shaped positioning groove. The chuck leveling mechanism 4 also includes a bracket 4.3 mounted on the base 1. The adjustment sleeve 4.2 is mounted on the base 1 via the bracket 4.3. The bracket 4.3 is provided with a support 4.23, and the adjustment sleeve 4.2 is rotatably mounted on the support 4.23. The adjustment sleeve 4.2 includes a mounting shaft 4.21 and a sleeve 4.22 mounted on the mounting shaft 4.21. One end face of the mounting shaft 4.21 presses against the support 4.23, and the other end face is provided with a limit pin 4.24. The material of the shaft sleeve 4.22 is a soft wear-resistant material, and in this embodiment, nylon is selected.

[0034] The chuck leveling mechanism 4 also includes a connecting plate 4.5, which is slidably mounted on the base 1 via a vertical guide rail mechanism 4.4. A compression spring 4.6 is provided between the connecting plate 4.5 and the base 1. The compression spring 4.6 is oriented in the same direction as the slide rail in the guide rail mechanism 4.4. The upper end of the compression spring 4.6 presses against the connecting plate 4.5, while the lower end presses against the base 1.

[0035] The transmission shaft 1 5.1 and the transmission shaft 2 5.2 are connected by a synchronous belt transmission. The transmission mechanism 5 also includes a tensioning wheel 5.3 installed at the synchronous belt. The end of the transmission shaft 1 5.1 connected to the power source is provided with a clutch, and the clutch is equipped with a polyurethane docking block.

[0036] The working principle of this utility model includes the following parts:

[0037] Adjustment of the split mount:

[0038] The mounting base includes a base 1 and an adjusting portion 2 mounted on the base 1. The base 1 and the adjusting portion 2 are connected by a concave-convex mating surface, wherein the mounting surface of the base 1 is a concave surface, and the mounting surface of the adjusting portion 2 is a convex surface, and the profile size of the convex surface is smaller than the profile size of the concave surface. This design allows the adjusting portion 2 to be fine-tuned relative to the base 1, thereby accurately adjusting the position of the chuck. In this way, a high chuck installation accuracy can be guaranteed even under lower processing and installation accuracy conditions, thereby improving the working accuracy of the winding machine. This design also reduces the actual installation contact surface between the base 1 and the adjusting portion 2, reduces the processing accuracy requirements for the base 1 and the adjusting portion 2, improves the contact stiffness between the base 1 and the adjusting portion 2, and reduces processing costs.

[0039] Adjustment of the chuck leveling mechanism 4:

[0040] The chuck leveling mechanism 4 comprises a chuck base 4.1 fixedly mounted on the second transmission shaft 5.2 and an adjustment sleeve 4.2 mounted on the base 1. The adjustment sleeve 4.2 is installed parallel to the second transmission shaft 5.2 and is located directly below it. A V-shaped positioning groove is defined below the chuck base 4.1, and the adjustment sleeve 4.2 is seated firmly within this groove. By tightening the adjustment sleeve 4.2 upward until it is seated firmly within the groove, the angle of the chuck base 4.1 is controlled, thereby limiting the horizontal position of the chuck.

[0041] The adjusting sleeve 4.2 is mounted on the base 1 via a bracket 4.3. The bracket 4.3 is provided with a support 4.23, and the adjusting sleeve 4.2 is rotatably mounted on the support 4.23. The adjusting sleeve 4.2 includes a mounting shaft 4.21 and a sleeve 4.22 that fits over the mounting shaft 4.21. One end of the mounting shaft 4.21 presses against the support 4.23, and the other end is provided with a stop pin 4.24. The sleeve 4.22 is made of wear-resistant nylon, which improves the wear resistance and service life of the structure. By removing the stop pin 4.24, the adjusting sleeve 4.2 can be disassembled and replaced, reducing the difficulty and cost of maintaining the adjusting sleeve 4.22. In addition, the adjusting sleeve 4.2 is tightly pressed in the V-shaped positioning groove, and part of the force on the inclined surface is decomposed, which further increases the wear resistance of the adjusting sleeve 4.2; and the adjusting sleeve 4.2 is tightly pressed in the V-shaped positioning groove, and the force on the left and right sides is balanced, which further extends the service life of the adjusting sleeve 4.2.

[0042] Compared with the traditional threaded adjustment structure, that is, the threaded adjustment bolt structure distributed on both sides, this design is not only convenient to adjust, but also more wear-resistant, has a long maintenance cycle, a simple structure and low cost.

[0043] Sliding adjustment of connecting plate 4.5:

[0044] The chuck leveling mechanism 4 also includes a connecting plate 4.5, which is slidably mounted on the base 1 via a vertical guide rail mechanism 4.4. A compression spring 4.6 is disposed between the connecting plate 4.5 and the base 1. The compression spring 4.6 is oriented in the same direction as the slide rails in the guide rail mechanism 4.4. The upper end of the compression spring 4.6 presses against the connecting plate 4.5, while the lower end presses against the base 1. The guide rail mechanism 4.4 and the compression spring 4.6 cooperate to push the connecting plate 4.5 upward, ensuring that the adjustment sleeve 4.2 remains firmly seated within the V-groove of the chuck base 4.1. This facilitates the vertical adjustment of the connecting plate 4.5 during fine-tuning of the chuck mechanism 3, enabling flexible adjustment of the chuck mechanism 3 and enhancing the operational flexibility of the entire system.

[0045] Vibration reduction design of the drive shaft:

[0046] Drive shaft 1 5.1 and drive shaft 2 5.2 are connected via a synchronous belt. Transmission mechanism 5 also includes a tensioner 5.3 mounted on the belt to maintain proper belt tension. A clutch is installed on the end of drive shaft 1 5.1 that connects to the power source. The clutch is fitted with a polyurethane docking block for effective shock absorption.

[0047] This flexible transmission connection design effectively reduces the vibration of the chuck and improves the stability during the winding process, thereby ensuring the winding accuracy.

[0048] The above embodiments are intended only to illustrate the technical concepts and features of the present invention. Their purpose is to enable those familiar with the art to understand the contents of the present invention and implement them accordingly. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications based on the spirit of the present invention shall be included in the scope of protection of the present invention.
