Description
Technical field
The present invention relates to field of measuring technique, refer in particular to a kind of bigbore measuring instrument that is used to measure.
Background technology
In routine duties, often run into the large-sized object bore and accurately measure difficult problem, especially protrude in the such problem of field of machining especially, in the space flight and aviation industry, the shell of spacecraft and lid, its bore can reach more than 5 meters, and between cooperation require very highly, add the accurately measurement of needs in man-hour.
The utility model content
Technical matters to be solved by this invention is: provide a kind of and can accurately measure bigbore measuring instrument.
For addressing the above problem, the present invention adopts following technical scheme to realize:
The heavy caliber measuring instrument, comprise the measuring instrument body, also comprise a par that is used for subsidiary, one end of described measuring instrument body is provided with the fixation measuring head, the other end of described measuring instrument body is provided with measurement mechanism and stator, described measurement mechanism comprises traverse measurement head, spiral handle and is used to be connected the carriage release lever of traverse measurement head and spiral handle, and described stator one end is fixedly connected on the measuring instrument body, and the other end is connected with carriage release lever.
Described measuring instrument body is a semicircular structure.
Described measurement mechanism and measuring instrument body are for being threaded.
Described carriage release lever is a screw rod.
Described stator by screw retention on the measuring instrument body.
The beneficial effects of the utility model are: owing to adopted par as supplemental measurement tool, length with par is benchmark, guaranteed the accurate of measuring basis, with the fixation measuring head is point of fixity, owing to connect by the screw thread carriage release lever between traverse measurement head and the spiral handle, when screwing spiral handle like this, drive a traverse measurement move left and right, the length that conveniently knows testee overgauge bar still is less than the length of par, be semicircular structure owing to having adopted the measuring instrument body in addition, make measured object still easily place, and stable, guaranteed the accuracy of measuring.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As Fig. 1, shown in Figure 2, the heavy caliber measuring instrument, comprise measuring instrument body 2 and a par 6 that is used for subsidiary, described measuring instrument body is a semicircular structure, one end of described measuring instrument body 2 is provided with fixation measuring head 1, the other end of described measuring instrument body 2 is provided with measurement mechanism and stator 4, described measurement mechanism and measuring instrument body 2 are for being threaded, described measurement mechanism comprises traverse measurement 3, spiral handle 5 and the carriage release lever 8 that is used to be connected traverse measurement 3 and spiral handle 5, described carriage release lever 8 is a screw rod, described stator 4 one ends are fixedly connected on the measuring instrument body 2 by screw 9, and the other end is connected with carriage release lever 8.
Embodiment 1:
Concrete operations of the present utility model are as follows, are that the testee 7 of 8000mm is an example with the bore:
1, utilizes the par of making a 8000mm length on the CNC planer type milling machine;
2, utilizing heavy caliber measuring instrument measurement standard bar, find out A face position, is the B face with a stator and a traverse measurement junction, is standard value X with the distance setting between A, the B
0=80mm;
3, will measure testee and be placed on the heavy caliber measuring instrument,, screw spiral handle, adjust the traverse measurement head, towards moving right, at this moment form correlative value X with the B face as this A according to the bore of testee
1
4, utilize outside micrometer to measure X
1=77.5mm;
5, because A is towards moving right in the above-mentioned steps 3, therefore as can be known, the length of the physical length overgauge bar of testee is promptly greater than 8000mm, so X
0-X
1=80mm-77.5mm=2.5mm;
6, according to step 5, the physical size of testee is as can be known: 8000mm+2.5mm=8002.5mm.
Embodiment 2:
In the such scheme, still be that the testee of 8000mm is an example,, form correlative value X with the B face if the physical size of testee then moves to left the A face less than the size of par with the bore
2, utilize outside micrometer to measure X
2, utilize X
0-X
2Draw difference X
3, utilize 8000mm-X
3Can draw the full-size(d) of actual testee.
