Abstract
The utility model relates to a kind of slide calliper rule, and particularly a kind of resiliency supported measuring jaw lengthens formula slide calliper rule, and whether the utility model is mainly applicable to detect inner groove diameter and meets the requirements.This utility model increases measuring jaw on the basis of original slide calliper rule, and during for preventing that measuring jaw is long brings measurement, measuring jaw distortion, trip frame and measuring jaw all employ spring, stress equalization when relying on the size of different spring force to make kind of calliper.This technical scheme solves the technical matters that valve pocket class inner ring groove of part diameter is difficult to detect.
Description
Technical field
The utility model belongs to Product checking technical field, and particularly a kind of resiliency supported measuring jaw lengthens formula slide calliper rule.
Background technology
When carrying out size detection to the product produced, often run into the inner situation with ring groove 12 of valve parts, this inner groove is less than its diameter due to external dimensions, and general outside is darker, so the measuring equipments such as existing slide calliper rule cannot Measurement accuracy, the object of detection can not be reached.
Summary of the invention
The purpose of this utility model is: the slide calliper rule providing a kind of accurate detection inner groove size.
The technical solution of the utility model is: described slide calliper rule comprise main scale 1, movable trip frame 3, fixing trip frame 4, spring 6, register pin 7, fixing measuring jaw 8 and movable measuring jaw 9;
Fixing measuring jaw 8 is fixed on main scale 1, fixing measuring jaw 8 and movable measuring jaw 9 are separately fixed on fixing trip frame 4 and movable trip frame 3, between movable trip frame 3 and main scale 1, spring 6 is installed, between activity trip frame 3 and fixing trip frame 4, spring 6 is installed, between fixing measuring jaw 8 and movable measuring jaw 9, spring 6 is installed, the elastic force sum of spring 6 when measuring jaw is in measuring position meets the requirement of dynamometry, and makes measuring jaw and trip frame stress balance;
Improve as to the one of slide calliper rule, the position that described slide calliper rule are greater than diameter to be measured on main scale 1 is fixed with register pin 7.
Improve as to the another kind of slide calliper rule, described slide calliper rule also comprise indicating gauge 2, and main scale 1 has tooth bar, and indicating gauge 2 is arranged on main scale 1, and its gear engages with the tooth bar on main scale 1.
Improve as to the another kind of slide calliper rule, described slide calliper rule are provided with trip bolt 10 on activity trip frame 3.
The beneficial effects of the utility model are: the utility model increases the length of measuring jaw, achieve the detection of inner groove, the technical program employs spring as support in addition, achieves dynamometry, friction force and bullet equilibrium of forces, ensure that the precision of measurement, testing result is more accurate.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is A-A cut-open view;
Fig. 3 is Workpiece structure schematic diagram;
In figure: 1 is main scale, 2 is indicating gauge, and 3 is movable trip frame, and 4 is fixing trip frame, and 5 is guide plate, and 6 is spring, and 7 is register pin, and 8 is fixing measuring jaw, and 9 is movable measuring jaw, and 10 is trip bolt, and 11 is handle handle, and 12 is inner groove.
Embodiment
Below in conjunction with accompanying drawing, this utility model is described further.
Main scale 1 is provided with movable trip frame 3, movable trip frame 3 can slide on main scale 1, and main scale 1 is fixed with fixing trip frame 4 by screw, and movable trip frame 3 and fixing trip frame 4 are separately installed with movable measuring jaw 9 and fixing measuring jaw 8.Between activity trip frame 3 and main scale 1, fixing swim frame 4 and activity and swim between frame 3 and be separately installed with spring 6.In addition, between fixing measuring jaw 8 and movable measuring jaw 9, spring 6 is also installed.Under the effect of all springs 6, when measuring jaw is positioned at detected value, balancing with joint efforts of dynamometry and spring.Because measuring jaw more easily produces distortion after lengthening under same dynamometry, so, if would not the problems referred to above be there are in the balance of making a concerted effort of dynamometry and spring.In addition, after slide calliper rule adding shock mount 6, when detecting without the need to applying power, measuring jaw can open automatically to be measured.
On main scale 1, the position being greater than measured value to be checked is fixed with register pin, by the Stroke Control of measuring jaw near measured value, this design can make the characteristic of spring not be changed on the one hand, ensure that the stability of slide calliper rule, be conducive to the fixing of spring on the other hand, ensure that spring does not come off.
During spring fitting, the scheme arranging one section of guide plate 5 at the two ends of spring 6 respectively can be adopted to fix spring 6, the two ends of spring 6 only need be sleeved on guide plate 5, without the need to other stationary installations, ensure to depart from the spacing scope inner spring 6 of register pin 7.
One as the technical program is improved, and activity trip frame 3 is provided with trip bolt, is used for fixing the position of movable trip frame 3, is convenient to reading and mobile slide calliper rule.
Another kind as the technical program improves, and activity trip frame 3 is also provided with indicating gauge 2, main scale 1 has tooth bar, wheel and rack engagement on indicating gauge 2, along with the movement of activity trip frame 3, the pinion rotation on indicating gauge 2, drives the indicators turn of indicating gauge.The benefit of installing indicating gauge is, can return to zero before measuring, meet the detection demand under various condition.
First, promote handle 11 now spring 6 shrink, to start to walk size with the check and correction of check and correction starting size ring gauge, mix up indicating gauge 2 zero-bit.
Lengthening measuring jaw is extend into inner ring groove of part place to unclamp and pull handle 11, now spring 6 launches, promotion activity trip frame 3 moves, and then drive and swim frame 3 coenosarc activity measuring jaw 9 move with activity, and contact with inner groove diameter dimension, read from indicating gauge 2 and record data, promotion pulls handle, measuring jaw is exited inner groove, then is that reference measurement compares with measurement inner groove size with standard size ring gauge, draw the actual detected value of inner groove.
