There are the avoid holes that gauge head is leant out, gauge head and measuring staff are from top to bottom mounted on the inside of shell, and gauge head is connected by measuring staff and sensor
It connects, sensor is located at the inside of stock, and sensor is fixedly mounted on connecting plate, and connecting plate is mounted on sliding block, and sliding block is set
Above bottom plate, several balls are installed between the two, ball is equally spaced apart from by retainer, and retainer is mounted under sliding block
Square, there are four end face limited block, end face limited blocks to carry out axial limiting, and end face limited block to sliding block for the arrangement that is square on bottom plate
There is certain gap radially with sliding block.
Further: the axial cross section of the shell is in convex shape structure, and the hole diameter detection apparatus further includes at least two
A gage button, gage button are mounted on the shoulder of convex shape structure.So set, shell insertion is then limited by gage button to the depth of gaging hole
It is fixed.
Present invention effect achieved are as follows:
Hole diameter detection apparatus of the invention can eliminate influence of the hole true position error to be measured to inside diameter measurement, avoid detection
Device housing is interfered with to gaging hole.The special gauge being made of this hole diameter detection apparatus can be simultaneously to multiple on part
The diameter in hole measures, and has the characteristics that precision is high, measurement efficiency is high, and can be very suitable to avoid missing inspection and erroneous detection
High-volume, quick, high-acruracy survey demand on production line.

Specific embodiment
For clarity and conciseness, all features of actual implementation mode are not described in the description.However, should
Understand, much decisions specific to embodiment must be made, during developing any this practical embodiments so as to reality
The objectives of existing developer, for example, meeting restrictive condition those of related to system and business, and these restrictive conditions
It may be changed with the difference of embodiment.In addition, it will also be appreciated that although development is likely to be very multiple
It is miscellaneous and time-consuming, but for the those skilled in the art for having benefited from the disclosure of invention, this development is only example
Capable task.
Here, also it should be noted is that, in order to avoid having obscured the present invention because of unnecessary details, applying for text
Illustrate only in part with closely related apparatus structure and/or processing step according to the solution of the present invention, and be omitted and this
The little other details of inventive relationship.
Embodiment: referring to Fig. 1 and Fig. 2, one kind of present embodiment can eliminate the Pore Diameter Detection of hole true position error influence
Device, including end face limited block 1, stock 2, gage button 3, shell 4, bottom plate 5, retainer 6, ball 7, connecting plate 8, gauge head 9, measuring staff
10, sensor 11 and sliding block 12；
For the ease of workpiece whereabouts, the top of the shell 4 is equipped with chamfering.The axial cross section of the shell 4 is in convex shape
Structure, the hole diameter detection apparatus further include at least two gage buttons 3, and gage button 3 is mounted on the shoulder of convex shape structure, shell 4
It is inserted into and is then limited by gage button 3 to the depth of gaging hole.The lower part of the shell 4 is connect with the top of stock 2, and stock 2 is installed on
On connecting plate 8, it is provided with gauge head on the side wall of the shell 4 and leans out avoid holes, gauge head 9 and measuring staff 10 are from top to bottom mounted on shell
4 inside, gauge head 9 are connect by measuring staff 10 with sensor 11, and sensor 11 is located at the inside of stock 2, and sensor 11 is fixed
It is mounted on connecting plate 8, connecting plate 8 is fixedly mounted on sliding block 12, and sliding block 12 is placed in 5 top of bottom plate, is equipped between the two
Ball 7 is equally spaced apart from by several balls 7, retainer 6, and retainer 6 is mounted on 12 lower section of sliding block, and the position of ball 7 is by protecting
The constraint of frame 6 is held, ball 7 can move in a certain range with retainer 6, and there are four end faces to limit for the arrangement that is square on bottom plate 5
Position block 1, end face limited block 1 carries out axial limiting to sliding block 12, and end face limited block 1 and sliding block 12 exist centainly radially
Gap.The gauge head 9 is alloy gauge head.The ball 7 uses steel ball.
