Description

The equilibrium structure of the accurate nut of locking

Technical field

The utility model is the equilibrium structure of the accurate nut of relevant a kind of locking, especially refer to that a kind of swivel nut is on axostylus axostyle, can stablize securely the assembly on the axostylus axostyle is locked, lock usefulness and eliminate the high frequency noise that axostylus axostyle is produced effectively when running up to improve, and guarantee the life-span of axostylus axostyle and the technology of running accuracy.

Background technique

By known axostylus axostyle lock nut, mainly be to be used on the installing and locating machine shaft or the bearing on the ball screw.For nut and axostylus axostyle are fixed, first kind of traditional known techniques is to establish screw on nut, and screw fills clamp holder, utilizes bolt to be screwed into screw pushing tow clamp holder and nut is packed on the axostylus axostyle.Second kind then is to establish the circular groove of crosscut at the nut inwall, and establishes axial screw and extend to circular groove, in screw screw lock bolt, makes the deformation of nut inwall and nut is packed on the axostylus axostyle.No matter adopt aforementioned which kind of make the mode of fixed by nut on axostylus axostyle; when nut is positioned on the axostylus axostyle; produce the phenomenon of deviation of gravity center axostylus axostyle through regular meeting; and need do the work that center of gravity is adjusted; so that nut is the state of steadily of centre of gravity balance when being positioned on the axostylus axostyle; to avoid parts to rock, situations such as transmission accuracy attenuating and manufacturing noise take place.

The most traditional balance mode is to remove the mode of material, in overweight position boring, and to make it reach the state of balance.Yet, be not easy except that expecting that balance is not only processed, waste man-hour, increase cost, precision is difficult for effectively grasping, and adds the vibrations that produce man-hour, influences the nut lock state easily, and, remove material and be permanent damage, damage easily, reduce its serviceability, dismounting several times just can't be used after removing material once again.

Because of in view of the technology of known axostylus axostyle lock nut, many disappearances are arranged in practical operation, the applicant drops into research and development for a long time and is improved, the phase masses that can benefit the society.The achievement of the applicant's research and development, for example TaiWan, China that the applicant applies for is announced the blocking structure patent case and the TaiWan, China patent M379665 nut locking structure patent case of No. 268543 bearing lock nut patent case, TaiWan, China patent I262262 main shaft balance nut patent case, TaiWan, China patent M273418 high-speed main spindle and nut thereof.

Wherein, the TaiWan, China patent I262262 main shaft balance nut patent case that the application had, be not have equilibrium function at the known axostylus axostyle locknut of improvement, and the balancing technique of present known axostylus axostyle lock nut, be the balance mode of directly digging a hole and expecting, and produce disappearances such as operation inconvenience and waste man-hour.Yet the technology of this patent case mainly is to add balancing weight doing balance on nut, and this technology still has noise problem and balance not to attain perfect situation when implementing.And the blocking structure patent case of TaiWan, China patent M273418 high-speed main spindle that the applicant had and nut thereof is at the equalizing orifice that improves known axostylus axostyle lock nut, and the noise that is produced asks that it is to cover blocking at equalizing orifice, with noise-decreasing.Yet the technology of this patent case still has noise problem and balance not to attain perfect situation when implementing.

The applicant drops into the research and development of axostylus axostyle lock nut for a long time, accumulates suitable rich experience.During this, in view of the previous product of researching and developing and proposed patent application of the applicant, still having needs more perfect in the design again, is actively to drop into research and development again, through constantly studying, design and real the work and experiment, research and development achievement of the present utility model is arranged eventually again.For research and development painstaking effort and the legitimate rights and interests of guaranteeing the applicant obtain to ensure that whence mere formality in accordance with the law proposes patent application.
