Abstract
The utility model relates to a cylinder hole circle heart measuring device, including testing platform, the concentric cylinder body and establishing the articulated arm measuring engine on testing platform, the articulated arm measuring engine includes the articulated arm and establishes at the terminal accuracy of measurement of articulated arm that the top center of the concentric cylinder body is equipped with the recess with accuracy of measurement matched with, and accuracy of measurement is through establishing sensor and the computer link in the articulated arm measuring engine. Compared with the prior art, this measuring device can reduce the detection process, laborsaving, easy operation, and the device commonality is strong, can measure multiple different cylinder holes, and it is accurate to measure, and the error is little.
Description
Technical field
This utility model belongs to track field, especially relates to a kind of cylindrical hole center of circle measurement apparatus.
Background technology
At present, urban rail transit in China context of detection, for the measurement at the cylindrical hole center on subway bogie frame
The technology not had.Most of measuring methods are 3 points on measurement cylindrical hole circumference, then deduce circle by complicated calculating
The particular location in the post holes center of circle.Might not accurately measure on circumference yet with the measuring machine each measuring point of probe, and
Carry out three measurements, measurement error is than larger.Cylindrical hole for different-diameter will repeat such operation, not only accuracy
Low, workload is also big, and work efficiency is greatly affected.
Utility model content
The purpose of this utility model be exactly provide to solve the above problems a kind of laborsaving, measurement is accurate, simple to operate,
Many sizes cylindrical hole center of circle measurement apparatus of highly versatile.
The purpose of this utility model is achieved through the following technical solutions:
A kind of cylindrical hole center of circle measurement apparatus, including detection platform, concentric cylinder and be located at the pass in detection platform
Joint arm measuring machine, described joint arm measuring machine includes joint arm and is located at the measuring probe of joint arm end, and described is concentric
Cylindrical top center is provided with the groove matching with measuring probe, and described measuring probe is by being located at joint arm measuring machine
Interior sensor is connected with computer.
Described concentric cylinder is the ladder circle column structure being made up of the cylinder of multiple different-diameters, each cylinder straight
Successively decrease from top to bottom in footpath.
The diameter of described concentric cylinder sets according to the diameter of cylindrical hole to be measured, and the cylindrical fit of different-diameter is different
The cylindrical hole to be measured of size.
The top central recess of described concentric cylinder is and measuring probe diameter identical hemispherical.
Described joint arm measuring machine includes bearing, and joint arm measuring machine is located in detection platform by bearing.
Described joint arm is made up of multistage, and this joint arm is located on bearing, can move up and down.
Said apparatus, when using measurement, concentric cylinder are put into cylinder in the hole to be measured, are then surveyed joint arm
The measuring probe of amount machine is put in the ball groove on concentric cylinder top, and the coordinate position that cylindrical hole is located is passed through to pass by measuring probe
In sensor input computer, just obtain the coordinate position in the cylindrical hole center of circle of required measurement.
Compared with prior art, this utility model has the advantage that
1st, this measurement apparatus can reduce detection operation, laborsaving, simple to operate.Needed true in three ability of circumference survey in the past
Centering position, this device can be directly to cylinder hole measurement, as long as one-shot measurement.
Multiple difference cylindrical holes can be measured by the 2nd, this device highly versatile.A kind of center of circle measurement apparatus could only in the past
Detect a kind of cylindrical hole of size, be accomplished by changing measurement apparatus when carrying out the measurement of other centers of circle, using inconvenience, and this device
Realize carrying out center of circle positioning measurement to the cylindrical hole of different-diameter by arranging the concentric cylinder of different-diameter.
3rd, accurately, error is little for this measurement device.Need three measurement operations before comparing, then circle is recorded by calculating
The heart, this device only needs one-shot measurement, just can direct output result, measurement error greatly reduces.

Specific embodiment
With specific embodiment, this utility model is described in detail below in conjunction with the accompanying drawings.
Embodiment 1
A kind of cylindrical hole center of circle measurement apparatus, as Figure 1-4, including detection platform 2, concentric cylinder 3 and be located at
Joint arm measuring machine 1 in detection platform 2, joint arm measuring machine 1 includes joint arm 8 and the measurement spy being located at joint arm 8 end
9, measuring probe 9 is connected with computer by the sensor being located in joint arm measuring machine 1, and joint arm measuring machine 1 passes through
Seat 6 is arranged in detection platform 2.
The ladder circle cylinder that concentric cylinder 3 is made up of the cylinder of four different-diameters, the diameter of each cylinder is from top to bottom
Successively decrease, diameter sets according to the diameter of cylindrical hole 4 to be measured on subway bogie frame 5, the cylindrical fit of different-diameter is different big
Little cylindrical hole to be measured 4, Fig. 5 is the partial schematic sectional view of cylindrical hole to be measured.The top center of concentric cylinder 3 is provided with and surveys
The groove 7 that amount probe 9 matches, groove is hemispherical, identical with the diameter of measuring probe 9.Joint arm 8 is formed by two sections, should
Joint arm is located on bearing, can move up and down.
During measurement, concentric cylinder 3 is put in cylindrical hole 4 to be measured, then by the measuring probe 9 of joint arm measuring machine 1
Put in the groove 7 on concentric cylinder 3 top, the coordinate position that cylindrical hole is located is inputted meter by sensor by measuring probe 9
In calculation machine, just obtain the coordinate position in the cylindrical hole center of circle of required measurement.
