Description

Technical Field

[0001] The present invention belongs to the field of wire harness processing tools, and particularly relates to a cam-type open turntable mechanism. Background Art

[0002] In the wire harness processing industry, single or multiple cables are often wrapped with tape to protect the cables or fix multiple strands of cables to prevent them from loosening. Currently, the processing is usually carried out manually, which is time-consuming and laborious, with low efficiency. Moreover, the quality of manually processed products varies greatly, making it difficult to ensure high-quality products. In order to change the manual production method, improve production efficiency and product quality, modern operations require new technologies to be applied to machines to replace manual production.

[0003] The turntable mechanisms used in existing automatic tape wrapping technologies are usually large in size and vibrate strongly, making it very strenuous to hold for a long time. Therefore, the present invention designs a cam-type open turntable mechanism. Summary of the Invention

[0004] In view of the above problems, the present invention proposes a cam-type open turntable mechanism.

[0005] To achieve the above technical objectives and effects, the present invention is realized through the following technical solutions:

[0006] A cam-type open turntable mechanism includes a fixed connection mechanism, a cam rotation mechanism, and a disk rotation mechanism. The cam rotation mechanism is arranged above the disk rotation mechanism, and the cam rotation mechanism drives the disk rotation mechanism to rotate through a mutually meshing component provided between the cam rotation mechanism and the disk rotation mechanism.

[0007] As a further improvement of the present invention, the cam rotation mechanism includes a cam, a camshaft, and a driving motor. The camshaft passes through the cam and is coaxially connected to the driving motor, and the cam rotation mechanism rotates with the camshaft as the rotation axis.

[0008] As a further improvement of the present invention, the disk mechanism includes an open disk and a disk cover plate with the same shape arranged above. The disk cover plate is provided with a number of long slot openings distributed in an annular matrix and pointing to the center of the circle, and rollers are arranged at the long slot openings.

[0009] As a further improvement of the present invention, the meshing component is a slot opening arranged in a spiral shape on the surface of the cam and an arc-shaped roller on the open disk, and the pitch of the slot opening is equal to the arc length between two adjacent rollers.

[0010] As a further improvement of the present invention, the opening radian of the opening disc is less than or equal to the radian formed by two adjacent rollers.

[0011] As a further improvement of the present invention, it further includes an elastic connecting member arranged in the long notch, one end of the elastic connecting member is fixed in the notch, and the other end is connected to the roller.

[0012] As a further improvement of the present invention, the fixed connection mechanism includes a base, a rotary positioning wheel pressing plate and a rotary positioning wheel. The base and the rotary positioning wheel pressing plate have the same shape, and include a C-shaped support seat part for installing the opening disc and a platform support part for installing the cam rotation mechanism;

[0013] The opening disc rotates through a plurality of rotary positioning wheels arranged on the side surface along the rotary track formed by the rotary positioning wheel pressing plate and the base;

[0014] It further includes a rotary seat A and a rotary seat B vertically arranged on the rotary positioning wheel pressing plate, which are respectively connected to both ends of the horizontally placed camshaft.

[0015] As a further improvement of the present invention, both ends of the central axis of the rotary positioning wheel are respectively connected to the base and the rotary positioning wheel pressing plate. The outer side surface of the opening disc is provided with a surface groove, and the rotary positioning wheel is embedded in the surface groove of the opening disc in a manner tangent to the outer surface of the opening disc.

[0025] In order to make the objectives, technical solutions and advantages of the present invention more clear and understandable, the present invention will be further described in detail below in conjunction with embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0026] The application principle of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] As Figure 1-6 shown, a cam-type open turntable mechanism includes a fixed connection mechanism, a cam rotation mechanism and a disk rotation mechanism. The cam rotation mechanism is arranged above the disk rotation mechanism, and the cam rotation mechanism drives the disk rotation mechanism to rotate through a mutually meshing component arranged between the cam rotation mechanism and the disk rotation mechanism.

[0028] The cam rotation mechanism includes a cam 5, a camshaft 6 and a drive motor 8. The camshaft 6 passes through the cam 5 and is coaxially connected to the drive motor 8. The cam rotation mechanism rotates with the camshaft 6 as the rotation axis.

[0029] The disk mechanism includes an open disk 4 and a disk cover plate 11 with a consistent shape arranged above. The disk cover plate 11 is provided with a number of long slots 12 distributed in a circular matrix and pointing to the center of the circle. Rollers 3 are arranged at the long slots 12.

[0030] The meshing component is a slot arranged in a spiral shape on the surface of the cam 5 and a roller 3 arranged along an arc on the open disk 4. The pitch of the slot is equal to the arc length between two adjacent rollers 3. This ensures that the cam 5 is always meshed with the open disk 4 during rotation, avoiding jamming when the open disk 4 rotates. The opening radian of the open disk 4 is less than or equal to the radian formed by two adjacent rollers 3, ensuring that the open disk 4 can complete a 360-degree rotation.

[0031] It further includes an elastic connecting member disposed in the long notch 12. One end of the elastic connecting member is fixed inside the notch, and the other end is connected to the roller 3. Under the action of the elastic connecting member, the roller 3 is located at the outer end of the long notch 12 and can move slightly within the notch, reducing the noise generated when the cam rotates and meshes with the roller. The multiple rollers 3 at the upper end of the open disk 4 are arranged at equal distances from the center point of the open disk 4, and the distance between adjacent two rollers 3 is equal.

[0032] The fixed connection mechanism includes a base 1, a rotating positioning wheel pressing plate 10, and a rotating positioning wheel 9. The base 1 and the rotating positioning wheel pressing plate 10 have the same shape, including a C-shaped support seat part for installing the open disk 4 and a platform support part for installing the cam rotating mechanism.

[0033] The open disk 4 rotates along the rotating track formed by the rotating positioning wheel pressing plate 10 and the base 1 through a plurality of rotating positioning wheels 9 provided on its side surface. Specifically, both ends of the central axis of the rotating positioning wheel 9 are respectively connected to the base 1 and the rotating positioning wheel pressing plate 10. The outer side surface of the open disk 4 is provided with a surface groove, and the rotating positioning wheel 9 is embedded in the surface groove of the open disk 4 in a manner tangent to the outer surface of the open disk 4.

[0034] The cam rotating mechanism is fixed through a rotating seat A2 and a rotating seat B7 vertically provided on the rotating positioning wheel pressing plate 10, and is respectively connected to both ends of the horizontally placed camshaft 6.

[0035] The driving motor 8 used in the embodiment of the present invention is a bidirectional rotating motor that can rotate clockwise or counterclockwise, and drives the open disk 4 to complete an infinite 360-degree bidirectional rotation.

[0036] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of the present invention claimed is defined by the appended claims and their equivalents.
