Abstract
The utility model discloses an internal diameter measuring instrument. The internal diameter measuring instrument comprises a measuring instrument body, and is characterized in that a standard bar for assisting in measurement is further included, a fixed measuring head is arranged at one end of the measuring instrument body, a measuring unit is arranged at the other end of the measuring instrument body, and comprises a movable measuring head and a movable rod, one end of the movable rod is connected with the movable measuring head, and the other end of the movable rod is in threaded connection with the measuring instrument body. The internal diameter measuring instrument has simple structure and accuracy of measurement.
Description
Technical field
The present invention relates to field of measuring technique, refer in particular to a kind of measuring instrument that is used to measure internal diameter.
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 man-hour needs accurately to measure, especially structure is the large-sized object of circle, the measurement of its internal diameter is loaded down with trivial details especially, can not well guarantee on the precision.
The utility model content
Technical matters to be solved by this invention is: a kind of measuring instrument that can accurately measure internal diameter is provided.
For addressing the above problem, the present invention adopts following technical scheme to realize:
Internal diameter 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, described measurement mechanism comprises traverse measurement head and carriage release lever, and described carriage release lever one end is connected with the traverse measurement head, and the other end is threaded with the measuring instrument body.
Described fixation measuring end surface is the circular arc end face, and the end face of described traverse measurement head is the circular arc end face.
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, because carriage release lever and measuring instrument body are threaded, when screwing traverse measurement like this, drive the carriage release lever move left and right, convenience knows that conveniently the length of testee overgauge bar still is less than the length of par, in addition because the end face of fixation measuring end surface and traverse measurement head is the bulb end face, make the fixation measuring head better contact, guaranteed the accuracy of measuring with the object under test inwall with the traverse measurement head.
Description of drawings
The figure I is a structural representation of the present utility model; The figure II is a required par structural representation of the present utility model
1 is the fixation measuring head, and 2 is the measuring instrument body, and 3 are the traverse measurement head, and 4 is carriage release lever, and 5 is par, and 7 is testee
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As shown in Figure 1, internal diameter measuring instrument, comprise measuring instrument body 2 and a par 5 that is used for subsidiary, 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, described measurement mechanism comprises traverse measurement 3 and carriage release lever 4, and described carriage release lever 4 one ends and traverse measurement 3 is connected, and the other end is threaded with measuring instrument body 2.
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, internal diameter measuring instrument measurement standard bar is found out A face position, is the B face with measuring instrument one end face, and the data that the distance between A, the B is accurately measured are X
0
3, internal diameter measuring instrument is put into the testee inner radius,, screwed spiral traverse measurement head, towards moving right, at this moment formed the 2nd value X with the B face as this A according to the internal diameter of testee
1
4, X
1Less than X
0, then the testee internal diameter is greater than 8000, and it is exactly error that two-value is subtracted each other.
5, as the A face X that moves to left
1Greater than X
0, then the testee internal diameter is less than 8000, and it is exactly error that two-value is subtracted each other.
Claims (2)
1. internal diameter measuring instrument, comprise the measuring instrument body, it is characterized in that: 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, described measurement mechanism comprises traverse measurement head and carriage release lever, and described carriage release lever one end is connected with the traverse measurement head, and the other end is threaded with the measuring instrument body.
2. internal diameter measuring instrument according to claim 1 is characterized in that: described fixation measuring end surface is the bulb end face, and the end face of described traverse measurement head is the bulb end face.
