Abstract
The utility model discloses an automatic centering device is paid to screw lock, it includes the upper mounting and the lower mounting of screw lock payment batch, the upper mounting is fixed on upper mounting plate, is equipped with the slide rail on the upper mounting plate, is equipped with the slider that mutually supports with the slide rail at the stiff end of lower mounting, is equipped with four pre-compaction spring holes of rectangular array in the upper end of upper mounting plate, installs the pre-compaction spring in the pre-compaction spring hole, is connected with the lower fixed plate in the outer end of pre-compaction spring, is equipped with the fisheye bearing between upper mounting plate and lower fixed plate; the utility model discloses pay screw and screw hole automatic, quick adjustment offset when taking place the counter point skew at the lock, calibration screw and screw hole screw position are in order to reach the purpose that good screw lock was paid.
Description
Technical Field
The utility model relates to an automatic centering device is paid to screw lock belongs to the screw lock and pays the instrument field.
Background
The automatic screw machine which manually locks the point positions is adopted, and particularly, the point positions are easily inaccurate due to visual errors of eyes in the process of locking fine screws; the inaccurate locking point position easily causes the following problems: 1. the locking yield is low because the screw locking is high, the locking screw is eccentric and the like 2. in the locking process of the fine screw, the screw thread of the bottom hole is easy to be damaged because the position of the screw is not coaxial with the bottom hole of the screw, and the product is scrapped because the repeated locking cannot be carried out.
Namely: the existing screw locking automatic centering device is needed, when a locking screw and a threaded hole have point-to-point deviation, the offset is automatically and quickly adjusted, and the positions of the screw and the threaded hole screw are calibrated to achieve the purpose of good screw locking.
Disclosure of Invention
The technical problem to be solved by the utility model is to provide an automatic centering device for screw lock pair, which can automatically and rapidly adjust the offset when the screw of the screw pair is offset from the screw hole in a point-to-point manner, and calibrate the positions of the screw and the screw of the screw hole so as to achieve the purpose of good screw lock pair; the defects of the prior art can be overcome.
The technical scheme of the utility model is that: the utility model provides an automatic centering device is paid to screw lock, it includes last mounting and lower mounting that the screw lock was paid the electricity and criticized, go up the mounting and fix on last mounting panel, be equipped with the slide rail on last mounting panel, the stiff end of mounting is equipped with the slider of mutually supporting with the slide rail under, is equipped with four pre-compaction spring holes of rectangle array in the upper end of last mounting panel, installs the pre-compaction spring in the pre-compaction spring hole, is connected with the bottom plate in the outer end of pre-compaction spring, is equipped with the flake bearing between last mounting panel and bottom plate.
And the four prepressing spring holes of the upper mounting plate are provided with limiting bolts of prepressing springs.
The upper mounting plate is provided with mounting holes for the fisheye bearings, and the mounting holes are provided with bearing fixing bolts for the fisheye bearings.
Compared with the prior art, the utility model discloses automatic centering device is paid to screw lock, it includes screw lock pay the upper mounting and the lower mounting of criticizing, the upper mounting is fixed on upper mounting plate, is equipped with the slide rail on upper mounting plate, is equipped with the slider that mutually supports with the slide rail at the stiff end of lower mounting, is equipped with four pre-compaction spring holes of rectangular array in upper end of upper mounting plate, installs the pre-compaction spring in the pre-compaction spring hole, is connected with the lower fixed plate in the outer end of pre-compaction spring, is equipped with the fisheye bearing between upper mounting plate and lower fixed plate; in the structure, in the screw locking process, the point position deviation of the locking screw and the threaded hole can generate certain torque to be applied to the screw locking power batch; the screw lock power screwdriver transmits torque to the pre-pressing spring through the upper mounting plate; because the lower fixed plate is fixed, the spheroid of fisheye bearing is fixed on last mounting panel, and because the moment distribution that the hole site skew applied force moment is inconsistent at the epaxial pre-compaction spring's of 4 directions moment to produce the bearing and float and drive the mounting panel and produce the skew with moment balance, thereby through the position of adjustment slider, reach the effect of automatic searching center.
Meanwhile, the structure is formed by a conventional fisheye bearing, a pre-pressing spring and a limiting bolt, and is simple in structure and long in service life; the mechanical automatic calibration is realized, additional electric elements are not needed, the reaction time is short, and the synchronous calibration in the locking process can be realized; the swing prepressing force can be easily realized by adjusting the locking length of the bolt or the size of the spring, and the screw locking device is suitable for screw locking of various sizes.
