Fig. 2 is a kind of bearing profile of bearing dial gauge of an embodiment.
Specific embodiment
Below in conjunction with the accompanying drawings and embodiment is described in further detail to the utility model.It should be appreciated that this technology
Scheme can be equally applicable in the middle of amesdial.
As shown in Fig. 1 and Fig. 2, a kind of bearing dial gauge, including dial gauge body, the dial gauge body includes table body 1
And Measurement portion, the table body 1 includes value structure, and the Measurement portion includes lead column 2 and guide pin bushing 3, and the bottom of the lead column 2 connects
Measurement head 4 is connected to, the guide pin bushing 3 is fixedly connected on the outer surface of table body 1, and the table body 1 is opened with the junction of the guide pin bushing 3
Corresponding two through hole is provided with, the lead column 2 is arranged in the through hole and the guide pin bushing 3, and the through hole is led with described
To bearing 5 is connected between post 2, the value structure is installed in the lead column 2 on the interior section of table body 1.It is oriented to
Post 2, due to the restriction of bearing 5, makes lead column 2 not rock in measurement process, and lead column 2 is because no and guide pin bushing 3
Contact will not produce frictional force, therefore lead column 2 only has frictional force between self-lubricating bearing 5, but this frictional force is very little, bearing
5 setting is greatly reduced the frictional force that lead column 2 is subject to, and improves the certainty of measurement of dial gauge.
Wherein in one embodiment, the bearing 5 is self-lubricating bearing or ball bearing.Using self-lubricating bearing or
Person's ball bearing can reach the effect of lubrication lead column 2, and during using ball bearing, ball bearing is arranged in guide pin bushing 3, therefore
The cross section increase of guide pin bushing；During using self-lubricating bearing, due to the restriction of this body structure of self-lubricating, the length of guide pin bushing 3 can increase.
