Problems solved by technology

1: The corresponding manufacturing cost increases a lot, 2: The accuracy error cannot be completely resolved, 3: No matter the transmission load is heavy or heavy, it must be limited by the transmission length, 4: The movement speed of the transmission mechanism is slow and the service life is low
In short, the above all increase the manufacturing cost and maintenance cost of mechanical equipment

Abstract

The invention discloses a ball screw shake preventer which comprises a linear guide and shake preventers. A plurality of guide sliders are disposed on a linear guide. The shake preventers are fixed on the guide sliders and are connected a connecting rod. A screw fixed on moving nut holders passes each shake preventer on each guide slider. The ball screw shake preventer has the advantages of low cost, convenience in mounting and high precision.

Description

technical field [0001] The invention relates to the application field of numerical control machine manufacturing technology, in particular to a ball screw anti-shake device. Background technique [0002] At present, the ball screw transmission mechanism configured by general large-scale numerical control mechanical equipment, in order to solve the drooping shaking caused by the super long ball screw during movement, which affects the positioning accuracy and service life of the equipment. Most have the following solutions. A: Increase the diameter of the ball screw, B: Hydraulic support mechanism. Although the above solution can play a certain role, it has certain defects. 1: The corresponding manufacturing cost increases a lot, 2: The accuracy error cannot be completely resolved, 3: Regardless of the transmission load, it is limited by the transmission length, 4: The movement speed of the transmission mechanism is slow and the service life is low. In a word, the above al...
