Ball screw pre-tightening device

Abstract

The invention provides a ball screw pre-tightening device which comprises a supporting plate, a spring, a telescopic plate, a clamping plate, a rotating plate, a rotating shaft, a sucker, pre-tightening bolts, elastic air bags, arc clamping plates, a lower connecting ring and an upper connecting ring, wherein the inner wall of the supporting plate is connected with the spring; the telescopic plateis installed at the outer end of the spring; the outer end of the telescopic plate is connected with the clamping plate through a connecting rod; the rotating plate is arranged in the clamping plate;the clamping plate is connected with the rotating plate through the rotating shaft; and the sucker is pasted at the inner end of the rotating plate. The supporting effect is improved through the design, the pre-tightening bolts are installed at the upper end of the upper connecting ring and the lower end of the lower connecting ring, the elastic air bags are assembled at the inner ends of the pre-tightening bolts, the arc clamping plates are arranged at the inner ends of the elastic air bags, the dynamic pre-tightening function is realized through the design, and the device is convenient to use, convenient to operate and capable of improving the pre-tightening effect, and can be rapidly mounted and dismounted.

Description

technical field [0001] The invention relates to a ball screw pretensioning device, which belongs to the technical field of ball screw rods. Background technique [0002] When the existing ball screw preloading device preloads the ball nut seat, it usually only has static preloading, but cannot perform dynamic preloading, and the preloading effect is low. During installation, it is usually fixed on a lathe by bolts, which is cumbersome to install and disassemble, and it is also easy to cause slippage of the bolts. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a ball screw pretensioning device to solve the problems raised in the above-mentioned background technology. The present invention is easy to use, easy to operate, improves the pretensioning effect, and can be quickly installed and disassembly. [0004] In order to achieve the above object, the present invention is achieved through th...
