Description
The utility model belongs to the band scale directly read or the survey instrument of mark.
In machining, measure the survey instrument of using always in endoporus and outer garden vernier caliper, milscale and inside dial indicator etc. are arranged.The vernier caliper measurement precision is 0.05～0.02mm.But the pressure during in fact owing to reading difficulty and measurement between measuring claw and measured workpiece causes measuring error because of human factor.To requiring the general vernier caliper measurement of the high endoporus of dimensional accuracy, when measuring accuracy is not enough, need use inside dial indicator, take up room greatly because the inside dial indicator member is more, work in-process measuring workpieces endoporus is very inconvenient, the distance that it need remove cutter is big, and just energy measurement of darker processing length must be arranged.Key joint is widely used in the kinematic train of plant equipment, and the dimensional accuracy of the width of keyway, the degree of depth, symmetry and the depth of parallelism directly influences the assembling and the use of plant equipment.Now still do not have a kind of survey instrument and can measure the dimensional accuracy of keyway comprehensively.Not only loaded down with trivial details but also time-consuming to the keyway symmetry and the depth of parallelism with the general measure instrument.
The purpose of this utility model is to design the accurate keyway of a kind of permanent dynamometry and measures slide calliper rule, these slide calliper rule can make things convenient for the dimensional accuracy of carrying out aspects such as width of keyway, the degree of depth, symmetry and the depth of parallelism all sidedly to measure, and have advantages such as reducing artificial measuring error raising measuring accuracy.
The utility model is to realize like this, the accurate keyway of this permanent dynamometry is measured slide calliper rule by pit gauge (1), blade (2), trip bolt (3), the moving chi (4) in a left side, left side drafting board (5), groove width is moved chi (6), right drafting board (7), right moving chi compositions such as (8), its main points are: at the middle part of blade (2) groove width measuring claw (18) is arranged, all there is the length scale lower-left side and upper right side at blade (2), blade (2) also has the moving chi (4) in a left side, the downside that groove width is moved chi (6) has the vernier graduation upside that the length scale is arranged, groove width measuring claw (17) and right moving chi (8) are arranged on the moving chi (6) of groove width, on a left side, right moving chi (4,8) be equipped with the left side of adjustable extension elongation in the groove, right drafting board (5,7), length scale and measuring claw (15 are arranged on it, 16,19,20), the afterbody that groove width is moved chi (6) is a constant force frame (11) that has dial gauge (14), on all moving chis corresponding vernier graduation is arranged all, constant force frame (11) has two holes that are parallel to blade (2), with screw (13), spring (12) is pressed on constant force frame (11) on the moving chi (6) of groove width, dial gauge (14) is installed on the constant force frame (11), its measuring head is pressed on the plate washer (10), a trip bolt is arranged on the constant force frame (11), during measurement the moving chi (6) of groove width is fixed on the blade (2).
Drawings and Examples:
Fig. 1 is the accurate keyway slide calliper rule of permanent dynamometry synoptic diagram
Fig. 2 is the accurate endoporus slide calliper rule of permanent dynamometry synoptic diagram
Fig. 3 is the outer garden of a permanent dynamometry precision slide calliper rule synoptic diagram
Embodiment 1:
Using method:
A, groove width measure, and earlier the moving chi (6) of groove width are moved on to the big 1mm of width of key to be measured place with the fixing constant force frame (11) of trip bolt, again with milscale with the range finding that exists between the certain groove width measuring claw of groove width number to be measured, make dial gauge (14) to zero.The reading of measuring groove width gained dial gauge has just been represented the deviation of the actual groove width and the value of editing.
B, symmetry are measured: according to the length (length that left and right drafting board stretches out during measuring wheel hub key groove symmetry should equate, and the symmetry measuring claw should be measured the maximum at diameter of bore) of the left and right drafting board of the size adjustment of measured workpiece (5,7).Half of left and right moving chi reading difference is the deviate of keyway symmetry.
C, groove depth are measured: with vernier caliper commonly used.
D, the keyway measurement of paralleism: measure the symmetry at keyway two ends respectively, i.e. the deviation of the keyway depth of parallelism as can be known.
Embodiment 2:
Accompanying drawing 2 is the accurate endoporus slide calliper rule of the disclosed permanent dynamometry of the utility model, at the afterbody of vernier caliper commonly used the constant force frame of a band dial gauge is installed, the structure of constant force frame with install as previously mentioned, the hole measuring method is identical with the wide measuring method of keyway.
Embodiment 3:
Accompanying drawing 3 is the outer garden of the disclosed permanent dynamometry precision of the utility model slide calliper rule, and this slide calliper rule are the measurements in garden outside constant force frame that the afterbody at common vernier caliper adds the anti-dress of a band dial gauge promptly can be used for.The structure of constant force frame is the same.The constant force frame (11) of anti-dress links to each other with the afterbody of the moving chi of vernier caliper by spring (12), screw rod (13).The nut of adjusting screw(rod) (13) makes the plate washer of constant force frame and moving chi afterbody that the spacing of 2.5mm be arranged, fixedly make its measuring head stretch out frame body 2.5mm during dial gauge (14), to move chi before measuring and move on to fixedly constant force frame of the little 1mm of this size to be measured place, the range finding that edits between measuring claw with inside dial indicator or thickness feeler is a size to be measured, makes dial gauge to zero.The reading of measuring the gained dial gauge is the deviation of the physical size and the value of editing.
The accurate keyway slide calliper rule of permanent dynamometry can make things convenient for and accurately be used for comprehensive measurement of keyway dimensional accuracy, the outer garden of permanent dynamometry precision slide calliper rule can be used for producing by batch workpiece external diameter and linear measure longimetry effectively, and permanent dynamometry precision endoporus slide calliper rule can be advantageously used in the accurate measurement of endoporus of the workpiece of positive work in-process.Measuring Time has been saved in the application of these disclosed survey instruments, has improved measuring accuracy, has guaranteed processing and the quality of checking, for installation and the use of plant equipment provides good condition.Therefore applying of these survey instruments will have great practical value and economic implications.
