Description
Technical field
The utility model is related to a kind of dial bore gages, and in particular to a kind of steel ball can roller dial bore gage measure
Bar.
Background technology
It needs strictly to control Product Precision in many manufacture fields, this just needs targetedly cubing progress
Accuracy detection.When wherein detecting product internal diameter size, need to use dial bore gage measuring rod.Dial bore gage measuring rod to
Measure or examine endoporus, deep hole diameter and its form accuracy of part.
Currently, the steel ball that traditional dial bore gage measuring rod measures contact point is fixed on measuring rod by brazing,
When measuring the lower product endoporus of hardness, it is easy to product bearing tolerances when causing slightly to scratch to product endoporus, and assembling
Required precision is high, slightly scratches the accuracy that will influence to measure and causes product unqualified or even scrap.
Utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies of existing technologies, and providing a kind of steel ball can be in roller
Diameter dial gauge measuring rod, when measuring product endoporus, measuring steel ball can freely roll, to product hole wall when avoiding measuring completely
It scratches, the accuracy of measurement is also significantly promoted.
To achieve the goals above, the utility model is realized using following technical scheme：
A kind of steel ball can roller dial bore gage measuring rod, including handle, mounting platform and measurement head, the installation
Platform one end is fixedly connected with the handle, and the other end is detachable to install the measurement head, is provided at the top of the measurement head
Big mounting hole and small mounting hole, the big mounting hole are connected to the small mounting hole part, and being provided in the big mounting hole can
The big steel ball of free rolling is fixedly installed small steel ball in the small mounting hole.
Further, described measurement head one end is provided with screw thread, and the right end center of mounting platform is provided with threaded hole, institute
The screw thread rotation for stating measurement head is inserted into the threaded hole of the mounting platform.
Further, chamfering is processed on the top of the measurement head, and the inner hole wall of product is scratched when avoiding measuring.
The utility model has the beneficial effects that：
A kind of steel ball provided by the utility model can roller dial bore gage measuring rod, using double steel ball design structures,
When work, the big steel ball of grease lubrication is added in big mounting hole, when measurement, big steel ball can be rolled freely, and small steel ball is fixed not
It is dynamic, big steel ball and small steel ball interference fit, injury when avoiding measuring to product hole wall, while the accuracy measured also substantially carries
It rises.
Description of the drawings

Example is applied, the every other embodiment that those skilled in the art is obtained shall fall within the protection scope of the present invention.
A kind of steel ball provided in this embodiment can roller dial bore gage measuring rod, as shown in Figure 1, including handle 1, peace
Assembling platform 2 and measurement head 3,2 one end of mounting platform are fixedly connected with handle 1, and the detachable installation measurement head 3 of the other end measures
First 3 top is provided with big mounting hole 4 and small mounting hole 5, and big mounting hole 4 is connected to 5 part of small mounting hole, in big mounting hole 4
Be provided with can the big steel ball 6 of free rolling, being provided in small mounting hole 5 can the small steel ball of free rolling 7.It is designed using double steel balls
When work, the big steel ball 6 of grease lubrication is added in structure in big mounting hole 4, and when measurement, big steel ball 6 can be rolled freely, small steel ball
7 are fixed on small mounting hole 5, and big steel ball 6 and small steel ball 7 are interference fitted, and injury when avoiding measuring to product hole wall measures simultaneously
Accuracy be also substantially improved.The present embodiment is using double steel ball design structures, and when work, grease profit is added in big mounting hole 4
Sliding big steel ball 6, when measurement, big steel ball 6 can be rolled freely, and small steel ball 7 is fixed, and big steel ball 6 and small steel ball 7 are interference fitted,
Injury when avoiding measuring to product hole wall, while the accuracy measured is also substantially improved.
Preferably, 3 one end of measurement head is provided with screw thread to one as the present embodiment, and the right end center of mounting platform 2 is set
It is equipped with threaded hole, the screw thread rotation of measurement head 3 is inserted into the threaded hole of mounting platform 2, when measuring, can pacified as needed
Different type or the measurement head 3 of size dimension are installed on assembling platform 2.
One as the present embodiment is preferred, and chamfering is processed on the top of measurement head 3, and the interior of product is scratched when avoiding measuring
Hole wall.
It is above-mentioned although specific embodiments of the present invention are described with reference to the accompanying drawings, but not to this practicality newly
The limitation of type protection domain, those skilled in the art should understand that, based on the technical solution of the present invention, ability
Field technique personnel need not make the creative labor the various modifications or changes that can be made still in the protection model of the utility model
In enclosing.
