Abstract

The utility model relates to a vernier caliper, which comprises a main caliper, a fixing measuring detent of the main caliper, an auxiliary caliper, and a flexible measuring detent of the auxiliary caliper, which is characterized in that assemblage holes are drilled on the fixing measuring detent and the flexible measuring detent, locating Y-fittings are slantingly arranged in the assemblage holes of the fixing measuring detent and the flexible measuring detent. The locating Y-fittings are inwardly provided with locked clamp plates, screw shafts are arranged on the perpendicular locked clamp plates, and the screw shaft are provided with gaskets, springs, cappings and adjusting bolts. The Y-fittings are inwardly provided with measuring arms, which are fixed on the flexible measuring detent and the fixing measuring detent by the cappings and the adjusting bolts on the screw shafts, and the bottom of each measuring arm connects with the measuring detents. The utility model has the effects of multiple functions, convenient operation, compact structure, consummate layout, and easy implementation and the like.

Description

A kind of vernier caliper

The utility model relates to a kind of vernier caliper, is specially adapted to the measuring object that existing vernier caliper can not be finished.

The measuring instrument that existing Marl, Germany is produced, cylindrical handle is arranged, be connected with digital wash on it, be connected with measuring jaw under the cylindrical handle, its shortcoming is: this measuring instrument has changed the structure of existing vernier caliper, the cost height, moreover handle is cylindrical, be inconvenient to operate, also will frequently change accessory successively, not only bother but also time-consuming according to the object of measuring.

Task of the present utility model is that a kind of cost of proposition is low, need not come frequently to change successively a kind of vernier caliper of accessory according to the difference of measuring object.

Task of the present utility model is finished like this, it comprises main scale and fixing measuring jaw thereof on the vernier caliper, pay chi and movable measuring jaw thereof, it is characterized in that: fixedly be drilled with pilot hole on measuring jaw and the movable measuring jaw, location Y-piece angle mount is in the pilot hole of fixedly measuring jaw and movable measuring jaw, in the Y-piece of location the fastening pressing plate is housed, the vertical fastening on the pressing plate has a spiral shell axle, on the spiral shell axle packing ring is housed, spring, block and adjustment bolt, test arm is contained in the Y-piece of location, by the block on the spiral shell axle with adjust that bolt is fixed on movable measuring jaw with test arm and fixedly on the measuring jaw, the bottom of each test arm is connected with the measuring jaw of measuring object.

The utlity model has following effect: it improves on the basis that does not change original slide calliper rule primary structure, realized the many usefulness of a chi, has widened the breadth and depth of using, have easy and simple to handle, compact conformation, layout is improved effects such as easy to implement.

Drawing explanation: 1. slide calliper rule 2. fixedly measuring jaw 3. movable measuring jaw 4. pilot holes 5. location Y-piece 6. regulator bolts 7. bolts 8. fixedly test arm 9. movable test arm 10. measuring jaws 11. fasten the pressing plates 12. packing rings 13. springs 14. spiral shell axles 15. 16. adjustment bolts of blocking a shot

Describe embodiment in detail in conjunction with above accompanying drawing, the utility model is to install location Y-piece 5 on existing slide calliper rule additional, movable test arm 9 and fixing test arm 8, be equipped with in Y-piece 5 (see figure 4)s of location and fasten pressing plate 11, the vertical fastening on the pressing plate 11 has a spiral shell axle 14, packing ring 12 and spring 13 are housed on the spiral shell axle 14, block 15 is arranged on it and adjust bolt 16, location Y-piece 5 fork is contained in fixedly on the measuring jaw 2 and movable measuring jaw 3, regulator bolts 6 is fixed on the movable measuring jaw 3 and fixing 4 li of the pilot holes of measuring jaw 2, fixedly test arm 8 is contained in fixedly 2 li of measuring jaws by block 15 with to adjust bolt 16 fixing, it is fixing by block 15 and adjustment bolt 16 that movable test arm 9 is contained in 3 li of movable measuring jaws, and the bottom of each test arm is connected with the measuring jaw 10 of measuring object.

During use, when the fixedly measuring jaw 2 on the slide calliper rule contacts with movable measuring jaw 3, zero set, drive fixedly test arm 8 and movable test arm 9 on its location Y-piece 5, at this moment, measuring jaw 10 on the test arm is in the zero-bit state, turn block 15 and regulator bolts 6 are fastening, just can be to the width internal channel, narrow shape outer channel, big dimensional measurement in endoporus is young, longhole survey, the measurement of deep hole trench diameter, the measurement of wall thickness, the blind area is measured, the measurement of O RunddichtringO 45 degree vulcanization of rubber former intracavity diameters, the chamber type diameter measurement of formpiston, and can implement the measurement of the external pitch diameter of thread.A this chi multifunctional measuring has practicality, convenience, science, reliable effect.
