Embodiment 1

[0018] refer to figure 1 , a cradle top device, comprising a threaded shaft 1 with a thread on the upper end of the outer circumference, a threaded sleeve flange frame 2 connected to the outside of the threaded shaft 1, a top shaft 4 connected to the threaded shaft 1, and a top shaft fixed on the top shaft 4. The top 3 at the upper end, the cradle frame body 5 fixed on the threaded sleeve flange frame 2, the lower part of the threaded shaft 1 is provided with a square hole 13, and the outer wall of the threaded sleeve flange frame 2 is provided with an anti-threaded shaft 1 The pull pin 6 that rotates reversely with the threaded sleeve flange frame 2; the top 3 is a round platform with a center hole, and the upper end of the threaded shaft 4 is fixed in the center hole of the top 3; the upper part of the threaded shaft 1 is provided with a stepped circle hole; the top shaft 4 is installed in the stepped hole of the threaded shaft 1, and the lower bearing spring retaining ring ...

Embodiment 2

[0021] refer to figure 2 The difference from the first embodiment is that the lower end of the outer wall of the threaded shaft 1 is provided with a circumferential groove 14 matching with the pull pin 6 to prevent the threaded shaft 1 and the threaded sleeve flange 2 from reverse rotation.

[0022] When in use, pull the pulling pin to the outside, insert the hand tool or electric tool into the square hole, turn the threaded shaft, and the threaded shaft will drive the top shaft to rise, so that the top will withstand the wire reel, fix the wire reel, loosen the pull pin, Under the action of the spring, the pulling pin is inserted into the circumference, thereby preventing the threaded shaft from loosening relative to the threaded sleeve flange.

[0023] The present invention adopts the method of thread transmission to adjust the position of the top. This method is relatively low in cost compared with the worm gear and worm, and the adjustment is simple. In addition, there is...

Abstract

The invention discloses a cradle centering device and aims to solve the problem that adjustment of centering positions in the prior art is troublesome. The cradle centering device comprises a threaded shaft, a threaded sleeve flange frame, a centering shaft, a tip and a cradle frame body, wherein threads are arranged at the upper end of the periphery of the threaded shaft, the threaded sleeve flange frame is connected outside the threaded shaft in a rotating mode, the centering shaft is connected to the threaded shaft in a rotating mode, the tip is fixed at the upper end of the centering shaft, and the cradle frame body is fixed on the threaded sleeve flange frame. A square hole is formed in the lower portion of the threaded shaft, and a pull pin preventing the threaded shaft and the threaded sleeve flange frame from rotating reversely is arranged on the outer side wall of the threaded sleeve flange frame. A threaded transmission method is adopted in the cradle centering device for adjusting positions of the tip, and compared with a worm and gear transmission method, the threaded transmission method is low in manufacturing cost and simple in adjustment; in addition, the pull pin is arranged for locking the threaded shaft, and the cradle centering device is safe and reliable in use.

Description

technical field [0001] The invention relates to a cradle top device. Background technique [0002] The top of the existing cradle frame is mostly a worm gear structure. The worm gear is driven by manual or electric motor rotation. At the same time, the threaded shaft installed in the worm gear is displaced in the direction of the central axis, thereby realizing the clamping of the cradle inner coil. The production and processing costs of the worm gear and worm structure are high, the adjustment is time-consuming and laborious, and the worm gear is easy to wear, which increases the cost. Contents of the invention [0003] The present invention aims to provide a cradle top device, which solves the problem of troublesome adjustment of the top position in the prior art. [0004] In order to solve the above technical problems, the present invention is achieved through the following technical solutions: a cradle top device, including a threaded shaft with threads on the upper e...
