Measurement table 3 is dial gauge, and the first pin 6 is straight pin, and the second pin 11 is rhombus pin.
Fig. 5 is arrived referring to attached drawing 1, support plate 4 is mainly used for installing dial gauge, measuring head (probe) and the cylinder cap of dial gauge
Firepower face contact, dial gauge are connect using the fastening screw 1 of resilient bushing 2 and side with support plate 4.Support plate 4 and mounting plate 5
Between be attached by welding, the perpendicular relationship of the two.The bottom surface of mounting plate 5 is close to put down where cylinder cap water hole
Face is equipped with the first protective case 9 and the second protective case 14 thereon, and straight pin and rhombus pin, the first protection are respectively provided with inside sheath
It is respectively arranged with a spring 8 between set 9 and straight pin and the second protective case 14 and rhombus pin, top uses a stud 10 respectively
It is fixed.Guide pin 7 passes through sheath, guiding and limit as straight pin and rhombus pin.Bolt 13 is used as determining for rhombus pin
Position and fixed makes its chamfered edge position with two sell the line of centres holding vertical, to ensure bolt conveniently and raising positioning accuracy.
Referring to attached drawing 3 and Fig. 4, support plate 4 and mounting plate 5 are welded into L-type structure, need to guarantee verticality requirement after welding,
And carry out weld seam slagging-off and grinding process.Due to measuring contact surface, the medial surface of support plate 4 and the bottom surface of mounting plate 5 are both needed to
Finishing processing is carried out, to guarantee its roughness and smoothness requirements.Be machined in support plate 4 second through-hole 401 (at two) and
First through hole 403 is respectively used to assembly correction pin 12 and resilient bushing 2, wherein the length of correction pin 12 is according to water hole distance fire
The size design in power face shortens 0.2mm, is 24.8 ± 0.01, can connect in this way to avoid correction pin when measurement with cylinder cap fire power face
It touches and influences measurement result.
Referring to Fig. 3 and Fig. 5, the first pin hole 501 and the second pin hole 503, threaded hole 502, the first pin are machined on mounting plate 5
Hole 501 is for assembling the first protective case 9, and the second pin hole 503 is for assembling the second protective case 14.
In conjunction with Figure 11 and Figure 12, the outer circle 1403 of the second pin hole 503 and the second protective case 14 uses transition fit, the first pin
The outer circle 903 of hole 501 and the first protective case 9 also uses transition fit, and threaded hole 502 is used for the limit of the second protective case 14 and consolidates
It is fixed.
In conjunction with Fig. 7, the outer circle 601 of the first inner hole 901 and straight pin of the first protective case 9 is gap-matched, and second
First inner hole 1401 of protective case 14 and the outer circle 1101 of rhombus pin are also gap-matched, it is ensured that can free skating between pin and hole
It is dynamic.Second inner hole 902 of the first protective case 9 and the second inner hole 1402 of the second protective case 14 are matched with guide pin 7 using transition
It closing, guide pin 7 is inserted into the groove 604 of straight pin and the groove 1104 of rhombus pin, and the diameter of guide pin is slightly less than groove width, with
Avoid bite.The edge of second protective case 14 is machined with arc groove 1404 at one, compresses entire sheath for bolt 13, prevents
Only it influences measurement accuracy because of rotation.
In conjunction with Fig. 6 to Figure 10, the external screw thread 1003 of straight pin lower thread hole 603 and stud 10 cooperates, and spring 8 is sleeved on
On optical axis 1002, lower end is contacted with counterbore 602, is tightened by screw thread by spring compression.The counterbore 1102 and counterbore 602 of rhombus pin
It acts on identical.The top 1001 of stud 10 carries out the processing of bilateral chamfered edge, convenient for manually tightening screw thread.Straight pin lower end be machined with compared with
Long chamfering, convenient for contacting centering with water hole aperture, the lower end 1103 of rhombus pin has carried out at chamfered edge on the basis of straight pin
Reason completed Quick bolt to eliminate positioning.
Cubing use process is as follows: (1) calibrate: first by cylinder cap stand upside down place, i.e., firepower is face-up.Two of cubing
The fire power face that pin 12 is close to cylinder cap is corrected, plane where straight pin and rhombus pin and cylinder cap water hole keeps discrete state.It adjusts manually
Whole percentage meter reading, because correction pin length is 24.8mm, and the standard value of size to be measured is 25mm (i.e. above-mentioned first distance
Value), therefore 0.2mm (increasing by 20 lattice clockwise) need to be tuned up on the basis of original zero point as new measurement zero point；(2) again by cylinder
Cover lie on one's side placement, i.e., upward by water hole to be detected, firepower outward facing sides.Refer to pressing straight pin and rhombus pin pair with two respectively
The stud answered fits closely pin bottom chamfer with aperture, reads percentage meter reading, is recorded as X1, then unclamps finger, and repetition is pressed
Pressure twice, is denoted as X2, X3 respectively, then surveyed water hole #1 is its average value T=25+ [1/3 relative to the position dimension of fire power face
(X1+X2+X3)], unit mm.Finally compared with design tolerance, if determining qualification, instead between 24.9mm and 25.1mm
It is then unqualified, shutdown adjustment need to be carried out.
By the way that it was verified that the cubing is easy to use, measurement accuracy is higher, not only ensure that processing quality, reduces simultaneously
To the dependence of three-dimensional coordinates measurement equipment.
Structure, feature and effect of the invention, the above institute are described in detail based on the embodiments shown in the drawings
Only presently preferred embodiments of the present invention is stated, but the present invention does not limit the scope of implementation as shown in the drawings, it is all according to structure of the invention
Think made change or equivalent example modified to equivalent change, when not going beyond the spirit of the description and the drawings,
