Description
Technical field,
The utility model belongs to the verification test technology, relates to a kind of verification test that installs the calibrating differential head error of indication using frock.
Background technology
When the calibrating of the differential head error of indication, because differential head rigidity is big, accuracy requirement is high, and convenient, reliable detection method that its verification process does not have causes detection efficiency very low.
A kind of calibrating of the existing differential head error of indication is at present marked with special-purpose gauge block such as 5 grades, makes anchor clamps with the milscale shelf.During calibrating, at first to select the milscale of corresponding specification, dismantle its shelf and the differential head matches.Not parallel because of milscale shelf gage button and differential head workplace, cause verification result unreliable.
Summary of the invention
The purpose of utility model is: propose a kind of calibration accuracy high, examine and determine easily the verification test of the differential head error of indication and use frock.
The technical scheme of utility model is: a kind of verification test of the differential head error of indication is used frock; Comprise be installed on the frock pedestal as the carriage of clamping mechanism with as the stationary installation of test benchmark mechanism; Said stationary installation is provided with the fixed muffle that end has the zeroing turn-knob; Have dead-beat fine setting gage button in this fixed muffle, said dead-beat fine setting gage button front end is provided with the spherical cap of surveying; Said carriage comprises successively differential head fixed muffle, quill and the force-measuring ratchet wheel that links to each other, and wherein, differential head measuring staff is contained in the differential head fixed muffle, and during test, saidly spherically surveys between the cap and places standard sample between the differential head measuring staff.
Said standard sample is 5 gauge blocks such as grade or corresponding special-purpose gauge block.
Said carriage is fixed on the frock pedestal by the slide block trip bolt.
Said fixed muffle, differential measurement bar and stationary installation are fixed by gib screw.
The advantage of utility model is: the verification test of the utility model differential head error of indication meets abbe ' s principle with the tool structure design; Solved in differential head and the milscale shelf clamping difficult problem that influences verification result because of mismate; Can carry out fast, stablize, effectively examine and determine the differential head error of indication easily at verification process, avoid unnecessary waste, effectively improve the stability of verification process; The reliability of verification result and calibrating efficient have guaranteed the calibrating quality.
Description of drawings
Fig. 1 is the structural representation of the verification test of the utility model differential head error of indication with frock;
Wherein, 1-zeroing turn-knob, 2-fixed muffle, 3-fine setting gage button, spherical cap, 5-differential head measuring staff, 6-quill, 7-force-measuring ratchet wheel, 8-differential head fixed muffle, 9-carriage, 10-stationary installation, 12-trip bolt, 13-slide block trip bolt, 15-frock pedestal, the special-purpose gauge block of 16-surveyed of 4-.
Embodiment
Explain further details in the face of the utility model down.
See also Fig. 1, it is the structural representation of the verification test of the utility model differential head error of indication with frock.Said differential head verification test comprises the carriage 9 and stationary installation 10 that is installed on the frock pedestal 15 with frock.Wherein, said stationary installation 10 is provided with the fixed muffle 2 that end has zeroing turn-knob 1, has dead-beat fine setting gage button 3 in this fixed muffle, and said dead-beat fine setting gage button 3 front ends are provided with the spherical cap 4 of surveying.In addition, said stationary installation 10 is provided with the trip bolt 12 that is used for fastening dead-beat fine setting gage button 3.The said zeroing turn-knob 1 that assembles, fixed muffle 2, dead-beat fine setting gage button 3, spherical cap 4, stationary installation 10 and the trip bolt 12 surveyed are formed test benchmark mechanism.
Said carriage 9 comprises differential head fixed muffle 8, quill 6 and the force-measuring ratchet wheel 7 that links to each other successively.Wherein, differential head measuring staff 5 is contained in the differential head fixed muffle 8, and fixing by trip bolt 12, and force-measuring ratchet wheel 7 links to each other with quill 6.Whole carriage 9 is fixed on the frock pedestal 15 by slide block trip bolt 13.Said differential head fixed muffle 8, quill 6 and force-measuring ratchet wheel 7 and trip bolt are formed clamping mechanism.
During this frock real work: in carriage 9, the locking trip bolt is adjusted the differential head and is in state to be checked differential head clamping.Rotate force-measuring ratchet wheel 7 workplace of differential head measuring staff 5 is contacted with the spherical cap 4 of surveying, utilize zeroing knob 1 to adjust zero-bit.Then, lock trip bolt 12 and slide block trip bolt 13 respectively, can carry out verification test.
5 gauge blocks such as grade or corresponding special-purpose gauge block 16 are put between the workplace and spherical survey cap 4 of differential head measuring staff 5 successively.Utilize again differential head force-measuring ratchet wheel 7 make differential head measuring staff 5 workplace, special-purpose gauge block 16 work and and the spherical cap 4 of surveying contact, read the indicating value of groove demonstration on the groove that exposes on the differential head fixed muffle 8 and the differential head quill 6.The difference of the indicating value of this check point and gauge block nominal size is the error of indication of this point.
The verification test of the utility model differential head error of indication meets abbe ' s principle with the tool structure design; Solved in differential head and the milscale shelf clamping difficult problem that influences verification result because of mismate, can examine and determine the differential head error of indication easily, avoided unnecessary waste at verification process; Effectively improved the stability of verification process; The reliability of verification result has guaranteed the calibrating quality, increases work efficiency 5 times.Quick, stable, effective aim have been reached.
