As shown in the figure: at a side mounting and fixing bracket 24 of base 5, opposite side is installed traversing carriage 17, and fixed support 24 is parallel to each other with traversing carriage 17, and two are detected dull and stereotyped 19 inboards that are installed on respectively on fixed support 24 and the traversing carriage 17; Traversing carriage 17 is slidingly connected on the base 5, is provided for promoting the pushing mechanism of traversing carriage 17 motions between traversing carriage 17 and base 5.In described pushing mechanism, the outer end of screw mandrel 13 utilizes bearing 28 to be installed on the base 5, and the inner of screw mandrel 13 is connected with the nut 15 that is installed on the traversing carriage 17, in the outer end of screw mandrel 13 handwheel 37 is installed.Slide block 26 is installed in bottom at traversing carriage 17, and guide rail 6 is set on base 5, and slide block 26 can slide in guide rail 6.When actual production, guide rail and slide block can exchange.
As a kind of form of measuring mechanism, can clock gauge 18 be installed on traversing carriage 17, the corresponding position on fixed support 24 is provided with reference block 2; Perhaps, clock gauge 18 is installed on fixed support 24, the corresponding position on traversing carriage 17 is provided with reference block 2; The thimble 7 of clock gauge 18 points to reference block 2.After using digital display dial gauge dynamically to find range, also can solve the loaded down with trivial details problem of changing.
The another kind of form of measuring mechanism is: directly connect index dial on handwheel 37, the pointer that points to index dial is installed on corresponding to the base at index dial place, when rotating handwheel, drive index dial and rotate together, by the direct sense data on index dial of pointer.
A kind of form as latch mechanism, latch segment bearing 29 can be set on base 5, left latch segment 1 and right latch segment 4 are slidingly connected on latch segment bearing 29, and, left side latch segment 1 and right latch segment 4 lay respectively at the both sides of slide block 26, after an end of screw rod 12 passes the hole that is arranged on base 5 or the latch segment bearing 29, are threaded with left latch segment, the other end at screw rod 12 connects handle 11, and handle 11 is positioned at the outside of right latch segment 4.Can adopt other form in addition,, when needs lock, rotate eccentric wheel, utilize eccentric eccentric throw that slide block 26 is pushed down, can reach the purpose of locking equally as in that an eccentric stiffener that is installed on the base is set above the slide block.
The another kind of form of latch mechanism is: after traversing carriage moves into place, directly with bolt slide block is fixed, at this moment a slotted hole should be set on slide block, bolt is positioned at slotted hole, and when needs locked, tighting a bolt got final product.
In the bottom of traversing carriage 17 transmission bracket 16 is set, nut 15 is installed on the transmission bracket 16, installation shaft bearing 31 on the close base 5 of screw mandrel 13 outer ends, bearing 28 is installed in bearing seat 31, the bearing cap 37 that is used for alignment bearing 28 is installed in the outside at bearing seat 31, is provided for the nut 32 of solid bearing 28 on screw mandrel 13, after screw mandrel 13 utilizes bearing 28 to install, friction force when helping to reduce rotary screw rod 13, handled easily.
Principle of work: the behind at fixed support 24 and traversing carriage 17 all has three to adjust nail, assemble detect dull and stereotyped 19 after, fixed support 24 is parallel with traversing carriage 17 adjustment.Before using fixed support 24 and traversing carriage 17 are fitted, make thimble 7 contact benchmark fast 2, digital display dial gauge 18 zeroings; Rotate handwheel 37, drive ball-screw 13 and rotate, nut 15 is moved along screw mandrel 13, drive slide block 26 by transmission bracket 16 and move, drive traversing carriage 17 by slide block 26 and move together along guide rail 6; When the registration of digital display dial gauge 18 was consistent with distance, turning handle 11 drove left latch segment 1 and right latch segment 4 is drawn close to slide block 26 respectively by screw rod 12, until grip slide 26, slide block 26 can not be moved and is locked.
This device is mainly used in the deflection degree that detects piston ring, and deflection is meant that distortion has appearred in two planes of piston ring, causes two uneven situations in plane.In the ordinary course of things, qualified piston ring can be by the slit in certain gap, and the piston ring of deflection just can not pass through.So can set two distances that detect dull and stereotyped 19 dynamically by this device, and then can detect the piston ring of multiple thickness.Detection method: make piston ring under action of gravity, pass through slit, can be qualified by the person, on the contrary defective.
