Abstract
Description
Technical Field
[0001] This utility model belongs to the field of tube processing and production, and specifically relates to a tube winding device for thin tubes. Background Technology
[0002] In traditional processes, the production of rubber parts by winding them onto thin tubes requires manual operation. Workers must manually adjust the position and tension after each turn, making the process very slow. During the winding process, workers need to constantly adjust the position and angle of the thin tube, which is especially physically demanding when the tube is long or heavy.
[0003] At the same time, due to the instability of hand movements, manual operation makes it difficult to ensure that the rubber parts are evenly wound on the thin tube, which may result in local winding that is too tight or too loose, affecting the appearance and performance of the product.
[0004] Therefore, the above problems urgently need to be solved. Utility Model Content
[0005] Purpose of the utility model: In order to overcome the above shortcomings, the purpose of this utility model is to provide a winding device for thin tubes. By setting up a tail clamping mechanism and a head clamping mechanism, the two work together to achieve automated clamping of thin tubes. Moreover, the design of the gearbox and motor allows the thin tube to automatically rotate around the axis after clamping, which greatly reduces the difficulty of winding tubes and improves the degree of automation and work efficiency. At the same time, the setting of the spacing adjustment mechanism enables this device to handle thin tubes of different lengths, increasing its versatility.
[0006] Technical Solution: To achieve the above objectives, this utility model provides a winding device for thin tubes, including a mounting frame, a spacing adjustment mechanism, a tail clamping mechanism, and a head clamping mechanism; the spacing adjustment mechanism is located between the two ends of the mounting frame; the spacing adjustment mechanism includes a spacing adjustment mounting frame, two sets of linear guide rails, a support plate, and a guide assembly; the spacing adjustment mounting frame is located in the middle of the mounting frame; the linear guide rails are mounted on the spacing adjustment mounting frame and located on both sides of the spacing adjustment mounting frame; the support plate is mounted on the linear guide rails and connected to the output ends of the two linear guide rails. The horizontal movement is achieved by a linear guide rail; the guide assembly is located between the two ends of the spacing adjustment mounting frame and is connected to the lower surface of the tray; the tail clamping mechanism is located on the tray; the tail clamping mechanism includes a tail clamping component and an L-shaped mounting block; the tail clamping component is connected to the tray through the L-shaped mounting block; the head clamping mechanism is located on the side of the mounting frame away from the tail clamping mechanism; the head clamping mechanism includes a head clamping component, a gear set mounting plate, and a motor mounting plate; the head clamping component is connected to the mounting frame through the gear set mounting plate and the motor mounting plate.
[0007] Furthermore, the spacing adjustment mechanism, through the design of linear guides and a support plate, enables adjustment of the spacing between the tail clamping mechanism and the head clamping mechanism. This allows the device to adapt to thin tubes of different lengths, meeting diverse processing needs without the need for frequent device replacements or large-scale modifications, greatly improving the device's versatility and applicability. The linear guides provide high-precision guidance, ensuring the stability and straightness of the support plate during movement and avoiding clamping errors caused by unstable movement. The L-shaped mounting block design provides sufficient support for the tail clamping assembly. Simultaneously, the tail clamping assembly can work in conjunction with the head clamping assembly to distribute the pressure on the thin tube during clamping, achieving stable clamping and precise driving of the thin tube, ensuring the stability of the thin tube during the winding process.
[0008] Furthermore, the tail clamping assembly includes a tail gearbox, a tail motor, a tail drive belt, and a tail three-jaw chuck. The tail gearbox is mounted on the horizontal arm of the L-shaped mounting block; the tail motor is mounted on the vertical arm of the L-shaped mounting block; the tail drive belt is positioned between the output end of the tail motor and the drive end of the tail gearbox, ensuring smooth transmission between them; the tail three-jaw chuck is located at the output end of the tail gearbox and faces the head clamping mechanism. The tail gearbox is mounted on the horizontal arm of the L-shaped mounting block, while the tail motor is mounted on the vertical arm, making the entire tail clamping assembly more compact and improving space utilization. The tail gearbox can amplify the output torque of the tail motor and adjust the output speed, allowing the thin tube to operate at a suitable speed. The tail three-jaw chuck can firmly clamp thin tubes of different sizes and ensure they do not loosen during operation. The tail drive belt can smoothly transmit the power of the tail motor to the tail gearbox, avoiding the impact and vibration that may result from a rigid connection.
[0009] Furthermore, the head clamping assembly includes a head gearbox, a head motor, a head drive belt, and a head three-jaw chuck.

The head three-jaw chuck is located at the output end of the head gearbox and faces the tail clamping mechanism. The head three-jaw chuck can firmly clamp thin tubes of different sizes and ensure that they do not loosen during operation. The head motor transmits power to the head gearbox via the head drive belt, ensuring efficient and stable power transmission and reducing energy loss and transmission errors. While controlling the opening and closing of the head three-jaw chuck, the head gearbox can also drive the head three-jaw chuck to rotate along the center line, which, in conjunction with the tail clamping assembly, greatly reduces the difficulty of winding tubes.
[0010] Furthermore, the guiding component includes a set of guiding limit blocks, several guiding columns, and guiding blocks; the guiding limit blocks are arranged on the spacing adjustment mounting frame and are located at both ends in the movement direction of the linear guide rail; the guiding columns are arranged between the guiding limit blocks; the guiding blocks are arranged on the guiding columns.

[0011] Furthermore, the guiding columns are arranged in a "pin" shape. The guiding columns arranged in a "pin" shape provide a more uniform stress distribution and a stable structure, improving the overall bearing capacity of the device.
[0012] Furthermore, a supporting crossbar is provided between the guiding limit block and the spacing adjustment mounting frame, and the two are connected through the supporting crossbar. The supporting crossbar provides a stable installation fulcrum for the guiding component, ensuring the stability of the device.
[0013] Furthermore, an auxiliary slider is also arranged on the linear guide rail; the auxiliary slider is arranged between the linear guide rail and the support plate. The auxiliary slider provides more stable support for the movement of the support plate on the linear guide rail, reducing the vibration that may occur during the operation of the device. [[ID=I0]]

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. Example
[0029] In this embodiment, as Figure 1 and Figure 2This utility model discloses a winding device for thin tubes, including a mounting frame 1, a spacing adjustment mechanism 2, a tail clamping mechanism 3, and a head clamping mechanism 4; the spacing adjustment mechanism 2 is located between the two ends of the mounting frame 1; the spacing adjustment mechanism 2 includes a spacing adjustment mounting frame 21, two sets of linear guide rails 22, a support plate 23, and a guide assembly 24; the spacing adjustment mounting frame 21 is located in the middle of the mounting frame 1; the linear guide rails 22 are mounted on the spacing adjustment mounting frame 21 and located on both sides of the spacing adjustment mounting frame 21; the support plate 23 is mounted on the linear guide rails 22 and connected to the output ends of the two linear guide rails 22, and is driven by the linear guide rails 22 to... The device moves horizontally. The guide assembly 24 is located between the two ends of the spacing adjustment mounting frame 21 and is connected to the lower surface of the support plate 23. The tail clamping mechanism 3 is located on the support plate 23. The tail clamping mechanism 3 includes a tail clamping assembly 31 and an L-shaped mounting block 32. The tail clamping assembly 31 is connected to the support plate 23 through the L-shaped mounting block 32. The head clamping mechanism 4 is located on the side of the mounting frame 1 away from the tail clamping mechanism 3. The head clamping mechanism 4 includes a head clamping assembly 41, a gear set mounting plate 42, and a motor mounting plate 43. The head clamping assembly 41 is connected to the mounting frame 1 through the gear set mounting plate 42 and the motor mounting plate 43.
[0030] Specifically, a high-precision ball linear guide can be selected for the linear guide 22 to ensure the parallelism and straightness of the guide, so as to ensure that the pallet 23 can move smoothly horizontally.
[0031] Specifically, the L-shaped mounting block 32 can be connected to the support plate 23 by bolts; threaded holes are machined on the support plate 23, and through holes are machined at the corresponding positions on the L-shaped mounting block 32. The bolts are passed through the through holes of the L-shaped mounting block 32 and screwed into the threaded holes of the support plate 23, thereby fixing the L-shaped mounting block 32 to the support plate 23; at the same time, in order to improve the stability of the connection, shims can be added between the L-shaped mounting block 32 and the support plate 23 to prevent the bolts from loosening due to vibration or other reasons during long-term use.
[0032] Specifically, the tail clamping assembly 31 and the head clamping assembly 41 need to be on the same horizontal plane to ensure clamping accuracy and facilitate tube winding.
[0033] In this embodiment, as Figure 1The tail clamping assembly 31 includes a tail gearbox 311, a tail motor 312, a tail transmission belt 313, and a tail three-jaw chuck 314. The tail gearbox 311 is mounted on the horizontal arm of the L-shaped mounting block 32. The tail motor 312 is mounted on the vertical arm of the L-shaped mounting block 32. The tail transmission belt 313 is located between the output end of the tail motor 312 and the transmission end of the tail gearbox 311 to ensure smooth transmission between the two. The tail three-jaw chuck 314 is located at the output end of the tail gearbox 311 and faces the head clamping mechanism 4.
[0034] Specifically, it is preferable to add an overload protection device such as a clutch or electronic overload protection module to the tail clamping assembly 31 to prevent equipment damage caused by overload; when the clamping force or motor load exceeds the set value, the overload protection device automatically cuts off the power to protect the device and the workpiece.
[0035] Specifically, the tail three-jaw chuck 314 is designed as a replaceable module. If the tube to be wound is a non-cylindrical tube, the corresponding chuck can be replaced, further improving the versatility of the device.
[0036] In this embodiment, as Figure 1 and Figure 2 The head clamping assembly 41 includes a head gearbox 411, a head motor 412, a head transmission belt 413, and a head three-jaw chuck 414. The head gearbox 411 is mounted on the mounting frame 1 via a gear set mounting plate 42 and is correspondingly arranged with the tail clamping mechanism 3. The head motor 412 is mounted on the mounting frame 1 via a motor mounting plate 43. The head transmission belt 413 is located between the output end of the head motor 412 and the transmission end of the head gearbox 411 to ensure smooth transmission between the two. The head three-jaw chuck 414 is located at the output end of the head gearbox 411 and faces the tail clamping mechanism 3.
[0037] Specifically, the head clamping assembly 41 can preferably integrate sensors such as torque sensors and position sensors to monitor the clamping force and workpiece position in real time, thereby further ensuring the stability and accuracy of the winding process.
[0038] In particular, an auxiliary bracket can be added below the head three-jaw chuck 414. The auxiliary bracket can be set on the plane of the gear set mounting plate 42 on the opposite side of the head gearbox 411 to improve the redundancy of the device. If the head three-jaw chuck 414 fails during the clamping process, the auxiliary bracket can also ensure that the thin tube will not fall and cause damage to the device, thus ensuring the stability of the tube winding.
[0039] In this embodiment, as Figures 1 to 3, the guiding component 24 includes a set of guiding limit blocks 241, several guiding columns 242 and a guiding block 243; the guiding limit blocks 241 are arranged on the spacing adjustment mounting bracket 21 and are located at both ends of the moving direction of the linear guide rail 22; the guiding columns 242 are arranged between the guiding limit blocks 241; the guiding block 243 is arranged on the guiding columns 242.
[0040] Specifically, as a preference, an elastic member can be added to the side of the guiding limit block 241 close to the guiding column 242 to prevent the guiding block 243 from colliding with the guiding limit block 241, which may affect the clamping stability or damage the device.
[0041] Particularly, as an optional solution, a sensor can be integrated into the guiding block 243 to be used for monitoring the pressure received in real time and preventing the guiding component 24 from being damaged due to excessive pressure.
[0042] In this embodiment, as Figures 1 to 3 , the guiding columns 242 are arranged in a "pin" shape.
[0043] Specifically, as a preference, the surface of the guiding column 242 can be painted, galvanized or coated with an anti-corrosion coating to improve its wear resistance and extend its service life.
[0044] In this embodiment, as Figure 3 , a supporting cross bar 25 is arranged between the guiding limit block 241 and the spacing adjustment mounting bracket 21, and the two are connected through the supporting cross bar 25.
[0045] Specifically, the supporting cross bar 25 is respectively connected to the spacing adjustment mounting bracket 21 and the guiding limit block 241 through bolts to further increase the connection strength.
[0046] In this embodiment, as Figure 1 and Figure 2 , an auxiliary slider 221 is further arranged on the linear guide rail 22; the auxiliary slider 221 is arranged between the linear guide rail 22 and the support plate 23.
[0047] Specifically, a locking member can be added beside the auxiliary slider 221. When the support plate 23 is adjusted to the appropriate position, the locking member can prevent displacement between the linear guide rail 22 and the support plate 23 and ensure the clamping stability.
[0048] The working principle of the above embodiment is:
[0049] This utility model discloses a tube winding device for thin tubes. In use, a head three-jaw chuck 414 is used to clamp one end of the thin tube, while the thin tube is held horizontally by the operator. Then, the linear guide rail 22 drives the support plate 23 to drive the tail clamping assembly 31, adjusting the distance between it and the head clamping assembly 41 until the other end of the thin tube can be clamped by the tail three-jaw chuck 314. Finally, the tail motor 312 drives the tail gearbox 311, and the head motor 412 drives the head gearbox 411, respectively driving the tail three-jaw chuck 314 and the head three-jaw chuck 414 to clamp the thin tube and achieve automatic rotation of the thin tube. At this time, the operator wraps rubber around the thin tube to perform the tube winding operation.
[0050] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of the present utility model, and these improvements should also be considered within the protection scope of the present utility model.
