Specific embodiment
The technical solution of the utility model is described in further detail below in conjunction with Figure of description.
As illustrated in figures 4-5, a kind of vernier caliper fixed and accurately measure stator slot wedge, including main scale 3 and vernier scale
4, the front end of main scale 3, which is equipped with to measure, determines pawl 5, and the front end of vernier scale 4, which is equipped with, measures pawl 6, and measurement is determined pawl 5 and measured in pawl 6
Fixing groove is measured equipped with stator slot wedge matched with stator slot wedge.
In order to realize fixation and measurement to commonly using stator slot wedge, stator slot wedge measures fixing groove and includes 2 kinds of measurement fixations
Slot, respectively for measure 70o stator slot wedges first measurement fixing groove 7 and for measure 60o/30 o stator slot wedges second
Measure fixing groove 8.70o stator slot wedges and 60o/30 o stator slot wedges pass through and 2 kinds of corresponding measure are set to fix using more
Slot realizes the fixation measuring to 70o stator slot wedges and 60o/30 o stator slot wedges.
Stator slot wedge both sides are fixed to clamp in order to realize, measurement determines pawl 5 and measures fixing groove 7 and second equipped with first
Measure the left part of fixing groove 8；It measures pawl 6 and is equipped with the first right part for measuring the measurement fixing groove 8 of fixing groove 7 and second.It is surveying
Amount determines pawl 5 and measures respectively to set a slot structure in pawl 6, is fixed to clamp convenient for being realized to the both sides of stator slot wedge.
For the ease of calculating measured value, it is symmetrical that the first measurement fixing groove 7 and second, which measures the left part of fixing groove 8 and right part,
Flute profile.By symmetrical setting, not only facilitate processing, when measuring, also allow for calculating the groove depth for measuring and needing to add
Numerical value.
In order to realize the measurement fixed structure of 70o stator slot wedges, first, which measures the left part of fixing groove 7 and right part, includes two
The parallel trough rim of item, trough rim 702 and first time trough rim 701 on respectively first, trough rim 702 and first time trough rim 701 on first
Spacing be equal to the height of 70o stator slot wedges, and equipped with the fit clearance be inserted into when measuring；On the inside of the slot of first time trough rim 701
End is equipped with the 70o slot bottoms side 703 to match with 70o stator slot wedges angle.Realize the measurement fixed structure of 70o stator slot wedges.
In order to realize the measurement fixed structure of 60o/30 o stator slot wedges, the left part and right part of the second measurement fixing groove 8 are equal
Including two parallel trough rims, trough rim 804 and second time trough rim 801 on respectively second, trough rim 804 and second time slot on second
The spacing on side 801 is equal to the height of 60o/30 o stator slot wedges, and equipped with the fit clearance being inserted into when measuring；Second time trough rim
801 slot medial end is equipped with 60o slot bottoms side 802, and the slot medial end of trough rim 804 is equipped with 30o slot bottoms side 803 on second, real
Now with the matching of 60o/30 o stator slot wedges.Realize the measurement fixed structure with 60o/30 o stator slot wedges.
For the ease of the accumulation calculating of width measurement, the length of first time trough rim 701 and second time trough rim 801 is 3mm.
And, integer size value 6mm is formed, the width dimensions of stator slot wedge is measured, is convenient for by the numerical value of 2 symmetrical lower trough rims
Accumulation calculating is equal to measured value and adds this fixed value 6.
It is interfered when fixing to clamp in order to prevent, R0.5 is made in trough rim 702 and the intersection on 70o slot bottoms side 703 on first
Circular arc processing；The circular arc that R0.5 is made in 60o slot bottoms 803 intersection at 802 and 30o slot bottoms is handled.Angle of the stator slot wedge at this
Portion's circular arc is typically no less than R0.5, not only easy to process by setting the circular arc of R0.5, and will not be interfered during measurement.
For the ease of measuring the depth of section of stator slot wedge, on first between trough rim 702 and first time trough rim 701 between
It is 4mm away from, the spacing on second between trough rim 804 and second time trough rim 801, tolerance 0 ,+0.1.70o stator slot wedges and 60
The depth of section of o/30 o stator slot wedges is generally 4mm, and+0.1 upper tolerance in slot convenient for being inserted into stator slot wedge, convenient for measuring.
When measuring 60o/30 o stator slot wedges, the both sides of 60o/30 o stator slot wedges are inserted into second and measure fixing groove 8
Left part and right part, after vernier caliper clamps, reading numerical values, be exactly after cumulative upper 6mm 60o/30 o stator slot wedges width dimensions；
Height dimension is by judging whether both sides are inserted into subject to the left part and right part of the second measurement fixing groove 8, it is impossible to be inserted into, then height gauge
It is very little bigger than normal, it is inserted into and cannot shake up and down, then size qualification；The judgement at 60o/30 o angles carries out after clamping, stator
The 60o/30 o bases of the both sides of slot wedge whether with second measure fixing groove 8 60o slot bottoms in 802 and 30 o slot bottoms, there are bright
Aobvious angle such as exists, then Angular Dimension is unqualified；The method of 70o stator slot wedges is measured with measuring 60o/30 o stator slot wedges
Method it is identical.
By stator slot wedge being set to measure fixing groove on vernier caliper, it is equivalent to a vernier caliper and drift cubing closes two
It is one, stable fixed stator slot wedge can be facilitated, realizes the accurate measurement to stator slot wedge.
The vernier caliper that a kind of shown in figure 4 above -5 fixes and accurately measure stator slot wedge is the tool of the utility model
Body embodiment has embodied the utility model in essence feature and progress, can be new in this practicality according to practical use needs
Under the enlightenment of type, the equivalent modifications of shape, structure etc., the row in the protection domain of this programme are carried out to it.
