Description
Technical Field
The utility model relates to an industrial robot technical field, in particular to industrial robot quill shaft joint cable arrangement structure.
Background
At present, in a six-axis small-sized industrial robot joint structure, one shaft and four shafts are rotating joints, a hollow speed reducer is often adopted for cable arrangement convenience, and a cable penetrates through the middle of the hollow speed reducer. When the robot joint rotates, the cables do twisting motion, and usually, the cables at two ends of the hollow joint are fixed, and only the fixed middle part is twisted. The longer the cable, the longer the cable life, the same twist angle, so it is desirable to extend the distance between the two fixing points as much as possible. However, because the small-sized industrial robot has a compact structure, the cavities at the two ends of the joint are also provided with a plurality of parts such as a motor, a belt wheel, a synchronous belt and a cable, and in order to prevent the cable from being worn by the parts during torsional motion, the fixed points at the two ends of the cable of the hollow joint are usually close to the hollow joint as much as possible, which can lead to the fact that the length of the cable which does torsional motion is short, thereby limiting the service life of the cable.
SUMMERY OF THE UTILITY MODEL
Technical problem to be solved
The utility model provides an industrial robot quill shaft joint cable arrangement structure solves current industrial robot quill shaft joint because the cable length of doing torsional motion is shorter and the problem of restriction cable life-span.
(II) technical scheme
In order to solve the technical problem, the utility model provides a technical scheme does:
the utility model provides an industrial robot quill shaft joint cable arrangement structure, includes the cavity reduction gear, the inside cavity that supplies the cable to pass that is equipped with of cavity reduction gear passes the cable one end of cavity with cavity reduction gear fixed connection, other end overcoat have tubular elastic component, the internal diameter of tubular elastic component is greater than the diameter of cable, tubular elastic component with cavity reduction gear fixed connection.
Wherein, preferably, the tubular elastic member is a spring.
Wherein, preferably, the tubular elastic member is a plastic tube or a metal tube with elasticity.
Preferably, one end of the cable is fixedly connected with the hollow speed reducer through a first clamp.
Preferably, the tubular elastic member is fixedly connected with the hollow speed reducer through a second clamp.
Wherein, preferably, one end of the tubular elastic member slightly protrudes out of the end of the hollow decelerator.
(III) advantageous effects
The technical scheme provided by the utility model, compared with prior art, following beneficial effect has:
the utility model discloses cable one end in the quill shaft joint with fixed, one end parcel is unfixed in tubular elastic component in addition, and tubular elastic component's internal diameter is greater than the cable external diameter, and the cable can the free rotation inside tubular elastic component, tubular elastic component and cavity reduction gear fixed connection, can not the back-and-forth movement. The length of the cable at the torsion section is prolonged under the condition of limited space, so that the service life of the cable is greatly prolonged; and the cable is arranged in the tubular elastic piece in the inner part, so that the cable can be prevented from interfering with other parts in the robot.
