The rotation of a large indicating needle adopts the double-stage driving of the toothed rack and a gear, and the rotation of a small indicating needle adopts double-stage gear driving. The utility model is convenient in use and the division value of the utility model can achieve 0.01mm.
Description
The utility model relates to a kind of indicating gauge calliper, particularly a kind of employing tooth bar, gear-driven indicating gauge calliper.
Existing is tooth bar, the gear one-level kind of drive by Americanized indicating gauge calliper, and scale division value can reach 0.1mm.
The purpose of the invention is to disclose the indicating gauge calliper that a kind of scale division value can reach 0.01mm.
The purpose of this utility model be achieved in that this novel indicating gauge calliper comprise outer ring, dynamometer spring, dial plate, fixedly gauge rod, movable gauge rod, with the tooth bar that movable gauge rod is fixed as one, different is:
Tooth bar, the transmission of gear two-stage are adopted in the rotation of big pointer, tooth bar and shaft gear engagement, shaft gear is connected with plate gear is coaxial, plate gear and central gear engagement, the axle that big pointer is fixed in central gear goes up and with its synchronous rotation, the ratio of gear of this driving-chain is K=157;
The two-stage gear drive is adopted in the rotation of little pointer, central gear and small pieces gearing mesh, with the coaxial minor axis gear that is connected of little plate gear and large stretch of gearing mesh, little pointer be installed in big plate gear spool on and with its synchronous rotation.
Because this novel indicating gauge calliper adopts tooth bar, the transmission of gear two-stage, and the micro-displacement between measurement face is amplified, and is convenient to reading and realizes that scale division value reaches the purpose of 0.01mm; Owing to adopt the device for measuring force of lengthening spring and pulley structure, then reduced the dynamometry of indicating gauge calliper in full measurement range and changed again; Because mechanism's (measuring claw parts) is a separate type with movement (wheel based part), carry out general assembly again after can assembling respectively again, therefore be convenient to assembling.
Below in conjunction with accompanying drawing the technical solution of the utility model is further described.
Fig. 1 is the inner structure synoptic diagram of the utility model preferred forms;
Fig. 2 is the inner structure synoptic diagram that removes present embodiment behind the core section;
Fig. 3 is that the A-A of Fig. 1 is to cut-open view;
Fig. 4 is the cut-open view of present embodiment along the axis;
Fig. 5 is the structural representation that attaching has annex on the measuring jaw;
Fig. 6 has the structural representation of another kind of annex for attaching on the measuring jaw.
In preferred forms of the present utility model, product size and profile can be identical with existing product or similar, also comprise outer ring, transparency cover, dial plate, the fixing basic element of character such as gauge rod pin 12 and activity 11, the structure of these parts and connection therebetween are similar to existing product; The both sides of movable gauge rod 11 are respectively arranged with left and right sides cushion block and left and right sides pressing plate 14,15 as its guiding mechanism that moves; Left and right sides cushion block and left and right sides pressing plate 14,15 are stuck in movable gauge rod 11 both sides respectively, and are installed in fixedly on the gauge rod 12; Tooth bar 1 is installed on the movable gauge rod 11, moves movable gauge rod 11, by being fastened on the tooth bar 1 and shaft gear 2 engagements on the movable gauge rod 11, shaft gear 2 and plate gear 3 coaxial being connected, plate gear 3 and central gear 4 engagements; The axle that big pointer 5 is fixed in central gear 4 is gone up and with its synchronous rotation.The ratio of gear K=157 of this driving-chain, this hour rack 1 moves 0.01mm, and big pointer 5 rotates lattice; Tooth bar moves 1mm, and big pointer 5 rotates a circle.Central gear 4 when rotating also with 6 engagements of small pieces gear, with small pieces gear 6 coaxial minor axis gears that are connected 7 and big plate gear 8 engagements, the axle that little pointer is installed in big plate gear 8 is gone up and with its synchronous rotation; If it is 50 lattice that little pointer turns around, and calibration lattice are represented sounding rod displacement 1mm, then the little finger of toe pin changes 7.2.Be calibration lattice, the gear number of teeth on this driving-chain can get 12,100,20,120 respectively, ratio of gear K=1/50.In order to eliminate drive gap, on the axle of big plate gear 8 hairspring is housed, to guarantee that it remains one way engagement in transmission process, produce certain ergometry during for the measurement face that makes fixedly gauge rod 12 and movable gauge rod 11 contacting and measuring under free state, the two ends of dynamometer spring 10 are installed in respectively fixedly on the gauge rod 12 and movable gauge rod 11; Change in order to reduce the dynamometry of indicating gauge calliper in full measurement range, dynamometer spring 10 adopts the lengthening springs, and required space length when it is walked around the pulley 13 that is fixed on the fixing gauge rod 12 with the minimizing telescopic spring.
Fixed in order to make each gear, the utility model inside is provided with head bearing plate 17, lower shaft board 18 and drive tab 21, the two ends axle journal of central gear 4 are loaded on respectively in the dead eye of head bearing plate 17 and lower shaft board 18, can be fixing by sprag 19 between head bearing plate 17 and the lower shaft board 18; On the packing ring 20 that lower shaft board 18 is fixed in fixedly gauge rod 12 is connected; Offer the groove that allows movable gauge rod 11 pass on the packing ring 20; The two ends axle journal of shaft gear 2 is loaded on respectively in the dead eye of lower shaft board 18 and drive tab 21; Also available little sprag 22 is connected between lower shaft board 18 and the drive tab 21.
In order to measure the thick and interior thin article of outer rim, as jewel etc., need long measuring jaw, but therefore be provided with the annex 16 of attaching on measuring jaw, this annex 16 can make the measuring jaw lengthening or change shape.
