Problems solved by technology
[0005] Due to the heavy weight of the wire reel, when the top is clamping the wire reel, the axial force and radial force are relatively large, and the frictional resistance of the bearing during work is large, resulting in a large pay-off tension. At the same time, the bearing used to support the top is Became a wearing part with a short service life

The invention discloses a stranding machine and a coil clamping device thereof. The coil clamping device comprises a fixed sleeve, a moving sleeve installed inside the fixed sleeve through threads in an axially adjustable manner, a center installed in the moving sleeve, centripetal ball bearings and thrust ball bearings with the outer rings fixed into the moving coil, a lubricating oil cup installed at the head of the center, a muffler installed on the fixed sleeve, a wrench socket installed at the tail of the moving sleeve, and a spring bolt component installed on an outer frame, wherein the installation end of the center is fixedly arranged in the inner rings of the centripetal ball bearings and thrust ball bearings in a sleeved manner. Thus, the radial force and axial force of the load of the coil clamping device of the stranding machine provided by the invention are borne by the centripetal ball bearings and the thrust ball bearings respectively, the bearings have small friction at work, and therefore, cable pay-off at low tension is realized. Moreover, the moving sleeve moves freely in the fixed sleeve, and the device has a long service life.
Description
technical field [0001] The invention relates to the technical field of cable processing, and more specifically relates to a stranding machine and a coil clamping device thereof. Background technique [0002] The stranding machine is used to twist multiple single wires together to form a cable. According to the way of stranding, it can generally be divided into cage type stranding machine, frame type stranding machine, tubular type stranding machine and disc type. Stranding machine etc. [0003] The wire reel clamping device of the stranding machine is used to clamp the wire reel to ensure that the wire reel can be positioned at a fixed position, and to ensure that the wire reel can perform stable rotation when the wire is paid out or taken up. [0004] The coil clamping device of the stranding machine includes a top, a movable sleeve and a fixed sleeve. One end of the top extends into the inside of the movable sleeve, and a bearing is provided between the top and the inner ...
