Abstract

The multipurpose active measuring instrument has double measuring arms for measuring the diameter of inner circle, single measuring arm for active measurement of inner and outer circles, through type active measurement of cut-in type centerless outer circle, continuous plane grinding height measurement, etc. The measuring arm is retracted and extended by utilizing the mutual displacement of the machine tool body and pulling the steel wire rope. The measuring signal is sent out by the improved micrometer comparator to perform rough and fine grinding.

The utility model discloses do not do big change to general lathe and can use, both can measure ordinary inside and outside circle diameter, also can measure deep groove, inslot outside circle diameter.

Description

Multipurpose active measurer

The utility model relates to the improvement of inside and outside garden in-process measuring instrument, belongs to the surveying instrument class.

Existing inside and outside first in-process measuring instrument mainly is made up of gauge head, measuring staff, test arm, elastic bearing, instrument shell, measurement instrument or sensor, hydraulic pressure actuating mechanism etc., when being used for measuring the inside and outside garden diameter of zanjon, groove or not being in the mood for outer first grinding diameter dimension, the pendulum angle of test arm is subjected to the restriction of elastic bearing intensity, gauge head can not enter zanjon, groove is directly measured, can only adopt indirect measurement, so just cause measuring accuracy not high, production efficiency is low.

The purpose of this utility model provides a kind of multiduty in-process measuring instrument, can measure first diameter in zanjon, the groove with two test arms, can or change measuring staff and increase the processing dimension that addition rod is measured outer first zanjon, groove diameter and is not in the mood for outer first grinding with first diameter in single test arm measurement zanjon, the groove again.When part processing arrives standard size, send signal by measurement instrument, machine tool feed system withdrawing.

The utility model is made up of gauge head 13, measuring staff 12, test arm 10, bearing supporting 45, instrument shell 1, measurement instrument 3, the wire rope 37 of boring linkage, swing-bar mechanism, plastic wrapper, skewback 24, addition rod 62 etc.Adopt two test arms 10 to measure first diameter in the zanjon of part 14, the groove, measurement instrument 3 usefulness screws 4 tighten up, and meter base 2 usefulness screws 5 are fixed on the upper arm 10.Test arm 10 is fixing with measuring staff 12 usefulness screws 11, and the other end of measuring staff 12 and gauge head 13 usefulness screws 15 are fixing.Adopt bearing 45 to cooperate rotation between test arm 10 and the bolster 8, slide plate 44 and elastic body 43 are arranged between test arm 10 and the supporting base 6, supporting base 6 is fixed on the base plate 34.2 stage clips 18 are arranged between surveying instrument shell 1 and the upper and lower test arm 10, between last test arm 10 and the following test arm 10 stage clip 17 is arranged, cone seat 22 and awl bar 21, stage clip 49 are between 2 test arms 10, and cone seat 22 has 2 mobile Xiao 19 near the conehead side of awl bar 21.There are bearing seat 35 hinges to be connected between surveying instrument shell 1 and the support 16.Garden dish fork 26 on the swing-bar mechanism seat 28 of band projection rotates around axle 27, drive with screw 42 and fix wire rope 37 on it, ending of wire rope 37 head ends 20 presses down

awl bar

21, and 2 mobile Xiao 19 are outwards mobile, promote upper and lower test arm 10 and horizontal measuring staff 12, gauge head 13 is promptly received.Through the wire rope 37 between support 16 and the swing-bar mechanism seat 28 metallic coil and plastic wrapper 36 are arranged.Dish fork 26 resets when the garden, and awl bar 21 resets, and gauge head 13 is promptly opened.Swing-bar mechanism seat 28 is fixed on the mobile lathe bed 32, with the skewback 24 that the roller 25 on the fork 26 is collided, is fixed on fixedly on the lathe bed 33.Mobile lathe bed 32 and the fixedly mutual displacement between the lathe bed 33, by the roller 25 of swing-bar mechanism collide with skewback 24, from, control upper and lower test arm 10 receive, open and surveying instrument shell 1 pendulum from or be flapped toward part 14, once bump, from finishing this two actions.Measurement instrument 3 is improved minimeters on utility model 8702730 bases, the arc fluorescent tube is improved to 4 groups of infrared emission with a lot of group photoelectric receiving arrangements with receiving pipe is linked to each other with light-operated circuit, makes simplified manufacturing process, and light-operated circuit is changed.Wherein 3 groups of

infrared tubes

67,68,72 are fixed on the scaleplate 69, and three corresponding printing opacity apertures are arranged, 1 group is fixed on the shift fork 76 that axle 75 rotates managing 70, and a corresponding arc printing opacity slotted eye with the consistent width of printing opacity hole diameter is arranged on scaleplate.There is the reflecting paper of the screening of diameter 1mm when infrared light source gauge pointer 71 upper ends.In process, gauge pointer 71 constantly moves, and sends corase grind 67, correct grinding 68, tarry matter 70, oversize 72 signals by 4 light-operated points, imports light-operated circuit into by many groups signal transmssion line 77, the automatic processing parts required size of control lathe.Multi-usage in-process measuring instrument size Control precision is 2 μ, and the utility model circuit is simple, and cost is low, uses easy to maintenance.
