Description

Rotating cylinder to prevent fatigue of pipes and wires

The invention relates to a rotary cylinder, in particular to a rotary cylinder structure that can prevent fatigue of pipes and wires and increase the service life.

The technical core of the traditional rotary cylinder (see Figure 1 and Figure 2) is that a cylinder A drives the fixture rotating body C to rotate with a shaft B. In order to provide a driving signal and air pressure to drive the rotary cylinder to act, the signal line D or air pressure pipeline is usually used. Electrically connected to the outer edge of the cylinder A and the fixture rotating body C, and in order to make the signal line D or pneumatic line rotate with the fixture rotating body C so as not to break the signal line or pneumatic line, the signal line D or air pressure is often reserved The length of the pipeline, when the cylinder A drives the fixture rotating body C to rotate, it will cause the pneumatic pipeline or signal line D electrically connected to the outer edge of the cylinder to produce a large curl state (as shown in Figure 2). When the pneumatic pipeline or signal line D After a long time of repeated crimping, it is very easy to cause fatigue and breakage of the pneumatic pipeline or signal line D, which affects safety and machine usage.

Secondly, the traditional rotary cylinder, in order to facilitate the winding, the pneumatic pipeline or signal line is arranged outside and not fixed, so that the pneumatic pipeline or signal line becomes a loose shape, and the pneumatic pipeline or signal line is often hooked during the operation of the machine, which affects the operation It is safe, and the wiring arranged on the outer edge also affects the beauty of the machine's appearance and produces a messy visual experience.

The purpose of the present invention is to provide a rotary cylinder to prevent fatigue of pipes and wires, which is characterized in that the wire end of the pneumatic pipeline or signal wire is fixed to the fixture, and the remaining wire segments are driven from the screw. The hollow structure of the rod passes through and is connected to the signal end. When the screw rotating fixture is driven to rotate, and the end of the thread rotates with the fixture, other wire segments are inserted into the hollow structure of the driving screw, and only a small amount of curling occurs. Reduce the degree of twisting of pipes and wires, prevent fatigue of pipes and wires, and increase the service life of pneumatic pipelines or signal wires.

In order to achieve the above-mentioned purpose, the rotary cylinder disclosed in the present invention is mainly provided with a driving screw group, a pitch seat, a pneumatic cylinder and a rotatable outer end of the box in the accommodating space of a machine box. Clamp; wherein the box is connected by the front wall, the rear wall, the left side wall, the right side wall and the bottom surface to define a box structure with accommodating space; the driving screw group is arranged at the bottom of the box accommodating space, including A hollow structure driving screw and a screw drive seat screwed to the driving screw. The front and rear ends of the driving screw are equipped with a bearing to be fixed to the front and rear walls of the box in a rotatable form. The screw driving seat is a screw It is connected to the middle section of the driving screw and includes a driving seat and a fixing seat. The driving seat is shifted to drive the screw to rotate, and the fixing seat and the adjustable pitch seat are fixed to each other to control the displacement distance of the driving seat.

The pitch adjustment seat is fixedly connected with the drive seat of the screw drive seat. It has a vertical seat, a transverse seat, and two adjusting screws arranged at the upper end of the vertical seat. The protruding length is adjusted by the adjusting screw. This limits the displacement distance of the drive seat, and then controls the rotation angle of the driving screw.

One end of the pneumatic cylinder is fixed on the back wall of the machine box, and the other end is fixed to the vertical seat of the distance adjustment base. The floating joint at the front end of the telescopic rod is fixed to drive the displacement of the distance adjustment base and indirectly linked to the displacement of the screw drive base. , The drive drives the screw to rotate.

The clamp is arranged on the outside of the front end of the machine box, and is fixedly connected with the smaller diameter fixing post at the front end of the driving screw, and is electrically connected to the pneumatic pipeline or signal line provided on the clamp, and only the end of the wire is fixed Fixtures, other pipes and line segments are driven through the hollow structure of the screw, and then connected with the cylinder Terminal or signal terminal is connected.

As a result, when the screw rotating fixture is driven to rotate and the end of the thread rotates with the fixture, other wire segments are inserted into the hollow structure of the driving screw, and only a small amount of curling occurs, which reduces the degree of twisting of the tube and wire and prevents the tube from being twisted. , Line fatigue occurs, which increases the service life of pneumatic pipelines or signal lines.

Regarding the technical core of the present invention, there are two parts: mechanism design and wiring design. The mechanism design is mainly configured in a machine box with a driving screw group, a pitch seat, a pneumatic cylinder, and a machine box. The end is a rotatable fixture; after the pitch adjustment seat is used to adjust the positioning and drive the rotation angle of the screw group, the pneumatic cylinder is linked through the pitch adjustment seat to drive the drive seat of the screw group to move a set distance, limit the rotation angle of the driving screw, and drive it at the same time The fixture rotates to a set angle to form a brand-new rotary cylinder based on the above-mentioned components and concepts; the wiring design is to electrically connect only the end of the pneumatic pipeline or signal line to the fixture, and the remaining line segments are driven by the hollow structure The screw passes through until the cylinder end or the signal end is connected. When the screw rotating fixture is driven to rotate the wire end with the fixture, the other wire segments are inserted into the hollow structure of the driving screw, and only a small amount of curl is produced. Reduce the degree of twisting of pipes and wires to prevent fatigue of pipes and wires. In addition to increasing the service life of pneumatic pipelines or signal wires, the hidden design of the wires can improve safety and show aesthetic appearance.
