Abstract

The invention belongs to the detection technology and relates to a fast measuring device for a multiple step sizes of a mechanical processing part. Especially, original multiple detections are realized through one measurement. Three dial indicators [7] and a limit rod [9] are fixed at the frame [6] of the measuring tool, with the corporation of a guide column [2], a spring [3], a guide sleeve [4] and a weight [11], the frame [6] moves up and down, the measuring heads of the dial indicators [7] act on the three steps of a measured part [12], the measuring data can be rapidly and visually read, and the fast, accurate and efficient measurement is realized.

Description

A kind of multi-step size one-shot measurement cubing

Technical field

The invention belongs to detection technique, relate to the quick measurement of a kind of step dimension multiple to machined part Device.

Background technology

Machining it is frequently necessary to the multi-step size of part is detected, generally use height gauge to divide Repetitive measurement, reads data on groove every time, and this metering system range estimation error is big, and accuracy of detection is poor, Detection efficiency is low, is not suitable with series-produced quick, economic requirement.

Summary of the invention

It is an object of the invention to: design and produce a kind of measurement inspection of three step dimension in machined part Tool, improving measurement accuracy, improves and measures efficiency.

The technical scheme is that a kind of multi-step size one-shot measurement cubing, it is characterised in that its bag Include pedestal 1, guide pillar 2, spring 3, guide pin bushing 4, gusset 5, framework 6, dial gauge 7, trip bolt 8, Gag lever post 9, screw 10, stick together code 11；Pedestal 1 is a cuboid, is provided with guide pillar 2 in the middle of its rear portion, Locking guide pillar 2 with screw 10, axially and the horizontal plane of pedestal 1, guide pillar 2 depends on guide pillar 2 from top to bottom Secondary be set with spring 3, guide pin bushing 4, stick together code 11；Guide pin bushing 4 is rigidly connected by gusset 5 with framework 6, fixing It is integrated；Framework 6 is in the front upper position of pedestal 1, and there are three upper lower through-holes framework 6 front portion, and three Block dial gauge 7 is separately fixed in the these three hole on framework 6, is locked by trip bolt 8；Dial gauge 7 Measure head to be directed at all the time on the tested surface of detected part 12；Gag lever post 9 screws in framework by its head threads Below 6 in respective aperture.

Described guide pin bushing 4 and guide pillar 2 snug sliding fit, the axial recessed R of guide pin bushing 4 and the convex R phase on guide pillar 2 Coordinate.

Upper its axial line of lower through-hole of three of described framework 6 front portion is perpendicular to the horizontal plane of pedestal 1.

The described code 11 that sticks together is sleeved on guide pillar 2, and its lower surface contacts with the upper surface of guide pin bushing 4.

The invention have the advantage that

A kind of multi-step size one-shot measurement cubing, effective improving measurement accuracy are provided, improve and measure efficiency, Meet series-produced online quick, economic requirement.

The schematic diagram of Fig. 1 duty of the present invention.

Fig. 2 is the left view of Fig. 1.

Fig. 3 is the top view after guide pin bushing 4 loads guide pillar 2.

Fig. 4 sticks together code 11 schematic diagram.

Detailed description of the invention

Below the present invention is described in further details.

The most referring also to Fig. 1, Fig. 2, Fig. 3, Fig. 4.

Detecting tool of the present invention includes pedestal 1, guide pillar 2, spring 3, guide pin bushing 4, gusset 5, framework 6, hundred Divide table 7, trip bolt 8, gag lever post 9, screw 10, stick together code 11.

When the present invention uses, first three pieces of dial gauges 7 screw 8 is fastened in three through holes of framework 6, By in the screwed hole of gag lever post 9 precession framework 6, by dial gauge 7 pre-pressing half-turn on the basis of standard block gauge Adjusting to zero-bit, now gag lever post 9 also contacts on a step surface of size to be measured, the chi of standard block gauge Very little and between three tested surfaces nominal dimension is consistent.

Spring 3 of the present invention is under the lower surface being enclosed within guide pillar 2 and being in guide pin bushing 4, and guide pin bushing 4 is by gusset 5 Connection and framework 6 are fixed as one, and tested part 12 is placed in the front portion of pedestal 1 horizontal plane, frame The lower section of frame 6, three step surfaces to be measured are under the gauge head of three dial gauges 7.

When the present invention is used for detecting, the code 11 that will stick together is sleeved on guide pillar 2, under yard action of gravity that sticks together, and guide pin bushing 4 move down compression spring 3 shrinks, now gag lever post 9 contacts in tested part intermediate step, three pieces of dial gauges The gauge head of 7 is changed into rising by lower limit state, and indicator then indicates the reality of size between tested part 12 step surface Deviation value.The code 11 that will stick together picks up disengaging guide pillar 2, under the elastic force effect of spring 3, guide pin bushing 4 moves, with Step drives gusset 5, framework 6 to rise, and dial gauge 7 gauge head separates with step surface to be measured, and the present invention completes one The action of size between three step surfaces of secondary detection.
