Abstract
A mechanical device for repairing screw pitch error of a micrometer micrometric screw, relates to the technical field of screw pitch error repair for screws, particularly to the technical field of mechanical devices for repairing screw pitch error of screws. A repairing mechanical device with an adjustable low-frequency motor is introduced to solve the problem that radial shake, axial movement and the like of the micrometric screw are easily caused by the fact that force is difficult to exert uniformly during manual repair, the grinding repair can be carried out uniformly, the repairing efficiency is improved, and abandonment caused by improper repair during the repair is avoided.
Description
Technical field
The present invention relates to the mechanical device technical field that the recovery technique field of screw pitch error, particularly screw pitch error are repaired.
Background technology
For the dimensional measurement of small parts, one of survey tool commonly used is micrometer.Micrometer is using after a period of time, because the frequency of usage to different screw threads position on the micrometer micrometric screw is different, cause its degree that is worn also different, occur producing deviation between the pitch at different screw threads position, thereby reduce the measuring accuracy of micrometer, need it is carried out regular reparation and calibration operation.Common repair mode is: the heat-proof device of on the other hand hand-held micrometer, knurled portions rotation by microdrum makes the micrometric screw of micrometer separate with the conciliation nut on the other hand, clamp-on the abrasive pastes of a little high grade at the internal thread of reconciling nut, then micrometric screw one end that the knurled portions rotation that the micrometric screw of micrometer of packing into makes microdrum is again ground micrometer back and forth equably by the abrasive pastes of reconciling on the nut inner thread is to the other end, to reach the purpose of eliminating screw-pitch deviation.Exert oneself evenly because manually-operated is difficult to reach in this repair mode, and the inhomogeneous micrometric screw generation that firmly easily makes is radially rocked and axial float, is difficult to grind equably, even cause pitch error to strengthen, precision reduces, even scraps.
Summary of the invention
The objective of the invention is: for the grinding step in the pitch error reparation that makes the micrometer micrometric screw carries out equably, a kind of mechanical device of repairing micrometer micrometric screw pitch error of special proposition.
Technical scheme of the present invention is: a kind of mechanical device of repairing micrometer micrometric screw pitch error, its structure as shown in Figure 1 can be along being consisted of with the mobile hold assembly 4 of clamping function and the driven gear 5 that meshes with long swing pinion 2 that is socketed on micrometer microdrum knurled portions of moving with long swing pinion 2 axis vertical direction by what arrange on the active rotation parts 3 of the belt length swing pinion 2 that arranges on pedestal 1, the pedestal 1 and the pedestal 1; Consisting of of active rotation parts 3: the long swing pinion 2 that closely is socketed on the output shaft 7 of adjustable low-frequency motor 6, be socketed respectively bearing 8 in the both sides of output shaft 7 long swing pinions 2, bearing 8 is connected as a single entity by bracing frame 9 and pedestal 1; The bottom of mobile hold assembly 4 is with dovetail groove, and this dovetail groove is socketed on the guide rail 10 vertical with long swing pinion 2 axis with its coupling, and can seesaw along guide rail 10, and guide rail 10 is connected as a single entity with pedestal 1; Have rectangular recess on the mobile hold assembly 4, in order to place micrometer; The front center position of mobile hold assembly 4 arranges fastening bolt 11 in order to the fastening micrometer that is placed; The bottom sides center of mobile hold assembly 4 arranges fastening bolt 12 in order to fastening forbidden moves hold assembly 4 seesawing along guide rail 10; Driven gear 5 is with center cylindrical hole, and micrometer microdrum knurled portions also realizes center cylindrical hole and its interference fit in order to can be socketed on certain tapering.
The present invention has the following advantages: the enforcement of mechanical device of the present invention, that has realized grinding in the pitch error reparation of micrometer micrometric screw evenly carries out, and has improved remediation efficiency, in having avoided repairing because improper the scrapping of causing of reparation.
Description of drawings
Fig. 1 is the structure chart of apparatus of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment the present invention is described in further detail:
When need are repaired the pitch error of using micrometer micrometric screw after a period of time, as shown in Figure 1, at first, the micrometric screw of micrometer is separated the knurled portions rotation of microdrum with the conciliation nut, clamp-on the abrasive pastes of a little high grade, the micrometric screw of the micrometer of then packing at the internal thread of reconciling nut; Secondly, driven gear 5 is socketed on micrometer microdrum knurled portions and realization and its interference fit; Then, the heat-proof device of micrometer is put into rectangular recess on the mobile hold assembly 4, by fastening bolt 11 that it is fastening; Mobile hold assembly 4 is moved to driving gear 2 directions, and driven gear 5 is moved forward and backward along guide rail 10 by fastening bolt 12 fastening forbidden moves hold assemblies 4 with driving gear 2 engagements are rear again; Require to adjust the rotating speed of adjustable low-frequency motor according to rotating speed, and the rotation direction by pole changer control low frequency electric machine, so that driving driven gear 5, driving gear 2 rotates, realize the knurled portions rotation of micrometer microdrum, micrometric screw one end that grinds equably back and forth micrometer by the abrasive pastes of reconciling on the nut inner thread is to the other end, to reach the elimination screw-pitch deviation.Be polished fewly in namely using by the dark pitch of mill, the more shallow pitch that is not worn or is worn is polished many, finally reach grind after the consistent reparation purpose of pitch.Use mechanical device of the present invention, that has realized grinding in the pitch error reparation of micrometer micrometric screw evenly carries out, and has improved remediation efficiency, in having avoided repairing because improper the scrapping of causing of reparation.
