Specific embodiment
In view of part in batch machining, internal slot diameter size need to only detect whether which is qualified, it is not necessary to read concrete
Measured value, therefore this utility model devises a kind of new appliance special for detecting, and inside groove diameter dimension can be used for quickly detecting.
With reference to accompanying drawing, this utility model is described in further details：
A kind of internal slot diameter cubing that this utility model is related to, including body 7, body 7 are I-shaped structure, and the structure can
To reduce the contact area of cubing and part end face, also it is reduced by causing survey block measurement end because of part processing end face Form and position error
The probability that face is interfered with part inside groove end face, while also mitigating cubing weight.
Installing hole is offered on the right side of the vertical plane of I shape, rotating bar 8 is installed in the installing hole, rotating bar 8 is
Three sections of staged column structures.When mounted, the axis of rotating bar 8 is passed through into body 7, while its being vertically connected with body 7
Place is respectively provided with 1 group of packing ring, respectively first group packing ring 4 and second group of packing ring 9.The front axle of rotating bar 8 offers screw thread in addition
Hole.
Rotating bar 8 is provided with rotation by the screwed hole on its front axle and surveys block 3, as shown in figure 5, rotate surveying block 3 for convex
Cylindrical structure, the rotation to be surveyed and be provided with drafting board on block 3, and the cross section of the drafting board is diamond structure.By one end of the drafting board
Go side is set to, the other end is set to not-go-end, the diameter dimension 0.1mm less than the diameter dimension of not-go-end of go side.
When rotation survey block 3 is installed, the small end that boss rotates survey block 3 is sleeved in rotating bar 8 down, and utilizes first
Trip bolt 1 is fixed, and between the first trip bolt 1 and rotation survey block 3 is provided with the 3rd group of packing ring 2.
Locating piece 5 is installed on the left of 7 I shape vertical plane of body, by two the second trip bolts 10 and two circles
Pin 6 is connected with body 7, it is ensured that, away from 7 upper surface of body apart from size b, size b is than part internal groove bottom for 5 upper surface of locating piece
Portion is to part end face apart from little 0.2mm of size or so.Wherein locating piece 5 is cylindrical structure, and is extended in its left side
There is the arc-shaped positioning drafting board that thickness is a.Size a less than part inside groove groove width size 0.4mm or so, make positioning drafting board with
Retain certain interval between groove width both ends of the surface, do not interfere with part during rotation.
When cubing assembling is carried out：
To ensure that cubing rotates flexible in part inside groove, as shown in Fig. 2 the circle of the positioning drafting board in figure on locating piece 5
Arc radius size R should be less than part inside groove radius size r, and the difference of R and r is 1～2mm.Simultaneously also need to meet the location-plate with
The distance between 7 center of body size C is more than size R, and the difference of C and R is 1～2mm.After treating that size R and C are determined, then
Locating piece 5 is arranged on body 7 while ensureing size b by straight pin 6 and the second trip bolt 10.
After to be positioned piece of 5 installations, then survey block 3 will be rotated on body 7, when mounted, the upper table of locating piece 5
Face is in same level with the upper surface for rotating drafting board on survey block 3, that is to say, that rotate the drafting board upper surface surveyed on block 3 away from body
7 upper surfaces are also b apart from size, are ensured by first group of packing ring of match grinding 4 or second group of packing ring 9, while also needing to ensure to turn
The rotation of lever 8 is flexible.
When the cubing is designed, as shown in figure 3, it is logical less than " only " word end radius to rotate " leading to " the word end radius R surveyed on block 3
R stops, and the logical differences with R only of R are approximately equal to part inside groove dimensional tolerance.Therefore, locating piece 5 and rotation in fig. 2 is surveyed between block 3
Just have two apart from X dimension, wherein when rotating " lead to " word end for surveying block 3 and going to outer body, that X is represented is X logical；When turn
When dynamic " only " the word end for surveying block 3 goes to outer body, what X was represented is that X stops.Wherein, size X is logical and X is only by part inside groove chi
It is very little to calculate given.Then the R for calculating theory further according to data such as rigging positions leads to, R stops size, size R in actual design
Logical and R only may be slightly larger than theoretical value 0.3mm or so, because size X in cubing is logical and X only needs assembling to ensure, repair to assembling
Positive stationary point surplus.
By above structure and Assurance of Size, this set appliance special for detecting made, you can for measuring part internal slot diameter chi
It is very little, it is not only quick but also accurate.
When using the measuring tool：
By the bar portion of rotating bar 8 upward, body 7 is placed on into part on the end face of inside groove one end, then rotates and turn
Lever 8 drives rotation to survey block 3 and rotates together, makes rotation survey the outer fix that the narrow one end of block 3 turns to body, now rotates survey block
3 are placed in part inside groove.
Then, the positioning drafting board of arc-shaped on locating piece 5 is close on one side wall of part inside groove, block 3 is surveyed when rotating
On " leading to " word end when being placed in 7 outside of body, start rotary motion bar 8, survey block 3 when rotating when rotating, now part inside groove
On a bit " lead to " word end pass through, expression part internal slot diameter size is not less than minimum dimension tolerance；" only " word end stops, table
Show that internal slot diameter size is not more than full-size tolerance, that is, represent that the spot size is qualified；Then continue to along part inside groove circumference side
To several points are detected successively, if detection is all that " leading to " word end passes through every time, " only " word end stops, and now " leads to " word end and return
To on the outside of body 7, illustrate along part inside groove circumferencial direction, the cubing detects that a circle is finished, while also illustrating part inside groove chi
Very little processing is qualified.
Rotating during surveying block 3, when " leading to " word end is pinned, then illustrating that part inside groove dimensioned is too small；Or work as
" only " word end is passed through, then illustrate that part inside groove dimensioned is excessive, as long as two kinds of situations one kind occur and mean that part is processed
Dimension overproof, part are defective work.
