Summary of the invention
The purpose of this utility model is to provide a kind of improved cubing for detection of outside diameter, and it can overcome cubing more complicated in prior art, operation inconvenience, time-consuming taking a lot of work, detect poor effect, degree of accuracy is not high simultaneously, the higher some shortcomings of cost of manufacture of cubing.
To achieve these goals, the technical solution of the utility model is: a kind of cubing for detection of outside diameter, it mainly comprises base plate, it is characterized in that: on base plate, be provided with successively dial indicator holder, movable measuring rod seat, lower location pole socket and fixing measuring rod seat, dial indicator holder is provided with dial gauge.
When use, the utility model is provided with base plate, and movable measuring rod seat and dial gauge are set on base plate.Workpiece for measurement is placed on lower backstay, linearly type of two lower backstays, side leans against on fixing measuring staff, presses handle, decontrols stop bit seat, by movable measuring staff spanner control activity measuring staff, makes movable measuring staff contact measured workpiece gently.Thereby form 3 point measurement outside diameters.And movable measuring staff and dial gauge link together, form straight reciprocating motion.Rotational workpieces, reads the numerical value on dial gauge.In the time that the outside diameter to workpiece detects, by standard component, the utility model is calibrated, and dial gauge is made zero.If the reading fluctuation range of dial gauge is in the scope of outside diameter tolerance, the diameter of this workpiece is qualified, otherwise is defective.This kind of detection mode rapid and convenient, accuracy of detection is higher simultaneously, and error is very little, and testing cost is lower, is easy to promotion and application.
Below in conjunction with drawings and Examples, the utility model will be further described.
Label in each accompanying drawing is expressed as follows: 1 standard component, 2 standard component seats, 3 take-up housing end blocks, 4 take-up housings, 5 dial indicator holder handles, 6 set nuts, 7 dial gauge limit bases, 8 dial gauge stop screws, 9 movable measuring staff spanners, 10 movable measuring staff spanner pins, 11 movable measuring staff spanner seats, 12 holders, 13 drop-down spring bases, 14 tension springs, 15 feets, 16 tension spring pins, 17 handle extension springs, 18 base plates, 19 handles, 20 dial gauges, 21 handle pin, 22 stop bit seats, 23 dial indicator holders, 24 damping push rods, 25 end caps, 26 measuring staff springs, 27 damping springs, 28 movable measuring staffs, 29 movable measuring rod seats, 30 interior hexagonals without a head, 31 workpieces for measurement, 32 times backstays, 33 fixing measuring staffs, 34 fixing measuring rod seats, 35 times backstay set nuts, 36 times location pole sockets, 37 dial indicator holder end caps, 38 handle bases, 39 glidepaths, 40 slide rail top lifting springs, 41 bottom end covers, 42 interior hexagonals without a head, 43 workpieces for measurement.
Described in the utility model is a kind of cubing that detects outside diameter, it mainly comprises base plate, its difference with the prior art is: on base plate, be provided with successively dial indicator holder, movable measuring rod seat, lower location pole socket and fixing measuring rod seat, dial indicator holder is provided with dial gauge.The both sides of dial indicator holder are provided with dial indicator holder handle, one end of dial indicator holder is provided with stop bit seat, dial indicator holder is provided with handle, the upper handle pin that is provided with, base plate and dial indicator holder are provided with corresponding slotted eye, in manipulation, be provided with handle extension spring, one end of handle extension spring is provided with tension spring pin, and the below of dial indicator holder is provided with tension spring and drop-down spring base.Lower location pole socket is provided with two lower backstays, is arranged with lower backstay set nut on lower backstay.The bottom of base plate is provided with feet.
Described movable measuring rod seat is provided with movable measuring staff, damping push rod and movable measuring staff spanner seat, movable measuring rod seat both sides are provided with dial gauge limit base and dial gauge stop screw, play " one draws a top " effect with below tension spring and the drop-down spring base of dial indicator holder, thereby can fix dial indicator holder in the process of measuring.One end of movable measuring staff is provided with end cap, between end cap and movable measuring staff, is provided with measuring staff spring; One end of damping push rod is provided with interior hexagonal without a head, between interior hexagonal without a head and damping push rod, is provided with damping spring; The movable measuring staff spanner pin that movable measuring staff spanner seat is provided with movable measuring staff spanner and matches with movable measuring staff spanner.Fixing measuring rod seat is provided with fixing measuring staff, and described fixing measuring staff is corresponding with the setting position of movable measuring staff.
In force, movable measuring staff spanner is drawn to holder direction, make movable measuring staff away from fixing measuring staff, again workpiece to be measured is placed on two lower backstays, side is leaned on and is fixed measuring staff, unclamps movable measuring staff spanner, makes movable measuring staff slowly near fixing measuring staff, until contact with workpiece for measurement, then see that with hand turning of work piece the reading of dial gauge changes.If the reading fluctuation range of dial gauge is in the scope of outside diameter tolerance, the diameter of this workpiece is qualified, otherwise is defective.Adopt dial gauge to detect the diameter of lining cover parts, not only improved the precision of cubing, also reading accurately, detect quick, efficiency is high.Many backstays, fixing measuring staff are set on multiple holders, have improved the versatility of cubing, the own school of cubing zero convenience simultaneously, cubing cost of manufacture is low, is easy to promotion and application.
