It helps hole that Measuring plate is connected with the positioning pin of supporter upper end, measurement pin is passed through into dimensional measurement hole and extends to pipe nipple,
If pipe nipple can be passed through by measuring pin, the distance of pipe nipple to tubular axis is equal to the dimensional measurement hole to the hole of centre bore
Away from if measurement pin cannot pass through pipe nipple, Measuring plate is taken out according to being rotated clockwise to another via hole simultaneously
It is put into positioning pin, measurement pin is passed through dimensional measurement hole and extended to pipe nipple again, if measurement pin still cannot pass through
Pipe nipple, then the distance of pipe nipple to tubular axis is equal to the dimensional measurement hole and previous dimensional measurement hole to centre bore hole
Away from the sum of half.It should be noted that when reading size, it should it is that the deviations of two measured holes is in opposite direction and could read,
If measuring pin to be biased in same direction, i.e., gap when cannot be inserted into all clockwise or counterclockwise, at this time cannot
Reading, only when one, the gap for the measured hole that cannot be inserted into, a counter clockwise direction clockwise just takes the two average value.
Compared with existing measurement scheme, using saving three coordinate metrology bulks after the device of the invention and method
Time reduces the labor intensity of worker, and the production efficiency for improving part reduces, and the production cost of part improves enterprise
The benefit of industry.

Fig. 2~Fig. 4 is the schematic diagram of another angle after measuring device and component assembly；
In figure, 1- Measuring plate, 2- supporter, 3- locating piece, 4- positioning bolt, 5- measures pin, and 11- cylinder, 12- pipe connects
Mouth, 13- ring.
Specific embodiment
Technical solution of the present invention is described further below in conjunction with attached drawing, but required protection scope does not limit to
In described.
By taking the distance for measuring pipe nipple 12 to 11 axis of cylinder is equal to this size of L ± 0.3 as an example, the present invention devises one
Measuring device is covered, such as Fig. 2~Fig. 4, which measures 5 component of pin shaft by Measuring plate 1, supporter 2, locating piece 3, positioning bolt 4
Composition.It is parallel to its axis direction on the end face of Measuring plate 1 and is provided with 7 dimensional measurement holes and location hole；Supporter 2 includes base
Seat, pedestal upper surface are provided with 2 positioning pins, and supporter 2 is connected by positioning pin with Measuring plate 1, and pedestal lower end surface has one
The internal diameter hole equal with 11 upper end outer diameter of pressurized strut cylinder, hole matches positioning with 11 upper end of cylinder；Totally two pieces of locating piece 3, every piece
There is a positioning plane on locating piece 3, two pieces of 3 upper ends of locating piece are connected with the lower end of supporter 2 by positioning bolt 4 and two
It is parallel to position plane, the positioning plane of locating piece 3 is bonded with the terraced steps on cylinder (to be had prominent at two on pressurized strut cylinder 11
Terraced steps, as shown in Figure 1, the ledge surface is two straight flanges；Measuring pin 5 is one and dimensional measurement hole, pipe nipple 12
The cylindrical body of flexible connection.7 dimensional measurement holes in Measuring plate 1 are along the circumferentially distributed of Measuring plate 1, dimensional measurement hole center
It is respectively equal to L-0.3, L-0.2, L-0.1, L, L+0.1, L+0.2, L+0.3 with the pitch-row at 1 center of Measuring plate, that is, covers pipe and connect
12 center of mouth to 11 axial line distance of cylinder upper lower limit value L ± 0.3, according to clockwise gradually between 7 dimensional measurement holes
It is incremented by 0.1mm；Location hole includes the centre bore positioned at 1 center of Measuring plate and the auxiliary on centre bore and measured hole line
The distance in hole, multiple via holes to centre bore is equal.
The Measuring plate 1 of the device is mounted on two positioning pins of supporter 2, two cylinders outstanding on locating piece 3
In the location hole of pin insertion supporter 2, and it is fixed with positioning bolt 4.When measurement, part is inserted into using measurement pin shaft 5
The bulk of the case where pipe nipple 12 measurement part.When measuring pin shaft 5 smoothly can be inserted into pipe nipple 12, size is the ruler
Bulk corresponding to very little measured hole, when measuring pin shaft more than 5 has hole that cannot all be inserted into, when pin shaft is between two holes
When, the mean value having a size of two empty correspondingly-sizeds.
By taking Fig. 1 as an example, by taking Fig. 1 measures size L ± 0.3 as an example, the specific embodiment of part is as follows:
Step 1: the two sides straight flange (trapezoidal convex surfaces straight flange) of component is bonded with 2 locating pieces 3 of measuring device and is put
Into device.
Step 2: choosing to install at the hole that 1 basic size of Measuring plate of device is identified, while measurement pin 5 is inserted into the hole
And the inner hole on the supporter 2 on component；
Step 3: if the measurement pin 5 of device is smoothly inserted into the hole on supporter 2, having a size of L, if cannot be suitable
Benefit insertion judges that the deviation for measuring pin 5 is continued to measure, if there is two by the measured hole for being biased to rotating device Measuring plate 1
A measured hole not can enter simultaneously, then the mean value of size is represented having a size of two holes.
