Description

Universal mechanism for fixed end of rope

Technical Field

Background

Various non-standard devices generally use linear sliding rails or optical axis sliding sleeves for linear movement. The linear slide rail or the optical axis sliding sleeve has limited stroke and large mass. When multi-axis motion is involved, linear slide rails or optical axis sliding sleeves need to be added to the equipment in all directions, the installation, adjustment and disassembly are very complicated, and the mass is multiplied. Subsequently, there has been a multi-axis robot with a smaller mass and capable of multi-axis movement, which is a more suitable solution for customers with strict requirements on the weight of the whole robot. When an existing multi-axis control robot is installed, the adjustment of a line is very complicated, and the initial angle between the line and an installation surface cannot be adjusted to be a right angle. When the existing multi-axis control robot moves at a high speed, the line is easy to bend repeatedly, and the service life of the line is shortened seriously. The mass of the threading wire binding mechanism of the multi-axis control robot cannot be too small, otherwise, the inertia required by the multi-axis control robot cannot be ensured. The binding wire contact mechanism of the multi-axis control robot is easy to wear due to the high rotating speed, but the binding wire contact mechanism is inconvenient to replace.

SUMMERY OF THE UTILITY MODEL

The above technical problem of the utility model is solved through following technical scheme: a cord-securing end gimbal mechanism comprising: the universal ball, the sliding sleeve, the universal ball fixing seat, the cover plate and the locking device; the universal ball fixing seat is provided with a through hole, one end of the through hole is provided with an annular bulge, the cover plate is installed at the other end of the through hole, and the sliding sleeve is fixed in the through hole through the annular bulge and the cover plate; the universal ball is arranged in the cavity and can freely rotate around the spherical center of the universal ball, and the universal ball exposes part of the spherical crown from the openings at the two ends of the cavity; the universal ball is provided with a rope through hole passing through the center of the ball, the rope passes through the rope through hole, and the locking device is arranged at the tail part of the rope.

Preferably, the locking device includes: a compression tube, a tapered nut, and an external thread; the afterbody of compression pipe is equipped with two at least extrusion pieces, the extrusion piece is around on the awl mesa, the outside is equipped with the external screw thread between the head of compression pipe and the afterbody, the tapering nut inner chamber is equipped with corresponding internal thread, and the afterbody of tapering nut still is equipped with the toper cavity for locking the extrusion piece.

Preferably, the diameter of the compression pipe head is smaller than that of the external thread.

The utility model discloses following beneficial effect has: the rope is arranged in the rope through hole of the universal ball, so that the bending of the rope can be reduced, the service life of the rope is prolonged, and the rope can still flexibly turn in high-speed motion; the extrusion sheet is locked through the tapered cavity at the tail part of the tapered nut, so that the rope is fixed, the locking device is easy to replace, and the maintenance and replacement of easily damaged parts are more convenient; by setting the diameter size of the compression pipe head to be smaller than that of the external thread, the universal ball can have a larger rotation angle.
