Description

A simple wiring device for the azimuth shaft of the turntable

technical field

The invention relates to the fields of electromechanical integration products and photoelectric products, in particular to an azimuth turntable wiring device.

Background technique

In the high-end field of modern industrial equipment, there are many electromechanical equipment that require multiple relative motions such as revolution and rotation. While mechanical equipment rotates continuously at 360°, multiple movements are required on the rotating body, and power and signals need to be transmitted between relatively rotating electrical components. In the turntable system where the size and weight are not strictly limited, conductive slip rings are generally used for the wiring of the rotating shaft. The advantage of the conductive slip ring is that it can realize unlimited continuous rotation and no cable winding; however, when using a conductive slip ring, the installation coaxiality is high, the signal shielding is difficult, and the system cost and size and weight will be increased.

In electromechanical equipment with limited size and weight, it is not possible to install a conductive slip ring. The shaft is generally routed by reserving a cable length margin, and then the cable is directly wound. Due to the high complexity of electromechanical equipment nowadays, the winding part of the cable must ensure that it does not rub against other parts, so it is necessary to design a take-up device for rotating the cable.

Contents of the invention

In order to overcome the deficiencies of the prior art, the present invention provides a simple and reliable cable routing device, which is used for accommodating the cable routing of the rotating shaft of the azimuth turntable, which can meet the requirements of continuous 360° forward rotation and reverse rotation without cable entanglement and scratching. , It is especially suitable for equipment with limited height and no wiring device installed on the top.

The technical solution adopted by the present invention to solve the technical problem is: a simple wiring device for the azimuth shaft of the turntable, which adopts a circular column structure, the cylindrical ring is fixedly connected with the rotating body of the azimuth turntable, and the inner cylinder and the outer cylinder of the circular column are fixed. The space is a cavity, the outer wall of the outer cylinder has a through wire slot around the circumference, and the lower surface of the cylindrical ring has a through wire hole; one end of the cable is fixed on the rotating body, and enters the wire box through the wire hole, along the inner The cylinder is drawn out horizontally from the wiring groove of the outer cylinder wall after one circle, and the other end is fixedly connected to the chassis wall.

The cable is provided with a flexible anti-knot whose diameter is twice the width of the notch of the wiring trough in the wiring trough.

The cylindrical ring is composed of two identical semi-cylindrical rings joined symmetrically along a plane passing through the axis.

The beneficial effects of the present invention are:

1) The movable part of the azimuth routing of the turntable is limited in the routing device, and there is no risk of cable entanglement and scratching;

2) The wiring device is simple in structure, easy to process and install, and has high reliability;

3) The wear and tear of the cable and the torsion force are small, which has little effect on the service life of the cable and increases the reliability of the system;

4) The shape of the wiring device is designed to be cylindrical, which can be organically integrated with the rotating load, which is beneficial to the beautiful structure.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings and embodiments, and the present invention includes but not limited to the following embodiments.

Implementation of the present invention includes the following links:

Step 1: Wire Box Design

The wire routing device of the present invention is only composed of a semi-closed wire take-up box, which is installed on the rotating body at an appropriate position and rotates together with the rotating body. The structure of the semi-enclosed take-up box is in the shape of a circular column, in which the inner cylinder is the winding column, the space between the inner and outer cylinders is the take-up space, and the side wall of the outer cylinder is opened with a ring of wire grooves for wire outlet and cable rotation. . One end of the cable is fixed on the rotating body and enters the wiring box from bottom to top, and after going around the inner cylinder for a circle, it is drawn horizontally from the wiring groove of the outer cylindrical wall to the fixed chassis wall, and the cable is fixed on the inside of the outlet slot. The soft knot (anti-knot) whose diameter is twice the width of the notch can not only satisfy the anti-knot plugged into the wiring box from the outside, but also prevent the cable from being pulled out of the wiring box and other parts when it is reversely rotated. Scuffing occurs.

Step 2: wiring box installation

The wiring box is spliced into a whole by two semi-circular boxes, which is mainly convenient for installation on special-shaped parts including I-shaped rotating bodies.

Step 3: Thread the cable head (S)

Define the cable terminal of the rotating body as the head end. After the cable at the head end is fixed, the cable enters the wiring box through the opening on the bottom of the wiring box (it can also be considered that the cable terminal passes through the bottom surface of the wiring box from the inside of the wiring box) through the hole downwards).

Step 4: Winding (also known as unwinding)

Define a forward rotation direction, take clockwise rotation as an example from a top view, stop the turntable at zero position, wrap the cable around the winding column once, the cable is stretched to the maximum length, and the payout is completed.

Step 5: Fix the end of the cable (E)

After finishing the wiring, leave a little more length as a margin and put it into the wiring box, punch a knot with a diameter twice the width of the slot at the outlet position and insert it into the wiring box, and then put the end of the cable horizontally Lead out to the chassis wall for fixing.

Step 6: Take up the wire

Rotate the rotating body in the opposite direction to return to the zero position of the turntable, the cable is in a loose state, and the take-up is completed.

The above are only preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, some improvements and modifications can also be made without departing from the principles of the present invention. These improvements and modifications should also be made. It is regarded as the protection scope of the present invention.
