Abstract
The utility model discloses a kind of keyseat center alignment instrument, including calibrated mount, mandrel, rolling bearing and spirit level, spirit level is connected to the upper reference plane of calibrated mount, spirit level is tubular type spirit level, inverted V-shape is presented in the lower reference plane of calibrated mount, and the vertex of the lower reference plane of calibrated mount is in circular arc, and calibrated mount is provided with rolling bearing, rolling bearing is located at immediately below spirit level, and mandrel is connected by rolling bearing with calibrated mount.The utility model has the advantages that：It is intended to use unifying datum principle, the positioning datum of the design basis of workpiece, measuring basis and workpiece is overlapped, so as to accurately ensure product quality.
Description
Technical field
It the utility model is related to engineering technology field, more particularly to a kind of keyseat center alignment instrument.
Background technology
With the rapid development of economy, industry also develops rapidly, along with industry develop rapidly to industrial processes and
The requirement of processed part is all improving.In milling key groove on shaft element, centering center is inevitably run into
The problem of, but it is incorrect due to instrument and method, often both lose time, again less than higher centering precision.This reality
With tubular type spirit level is taken in new, realize by it is traditional it is empirical be science type pair with spirit level level-off to swivel
Knife, centering precision is improved, save the time, reduce cost.
Utility model content
The purpose of this utility model is to provide a kind of keyseat center alignment instrument, it is intended to unifying datum principle, by work
The positioning datum of the design basis of part, measuring basis and workpiece overlaps, so as to accurately ensure product quality.
The utility model is achieved through the following technical solutions：
A kind of keyseat center alignment instrument, including calibrated mount, mandrel, rolling bearing and spirit level, spirit level are connected to school
The upper reference plane of positive frame, calibrated mount are provided with rolling bearing, and mandrel is connected by rolling bearing with calibrated mount.
Further, the spirit level is tubular type spirit level.
Further, inverted V-shape is presented in the lower reference plane of the calibrated mount.
Further, the vertex of the lower reference plane of the calibrated mount is in circular arc.
Further, the rolling bearing is located at immediately below spirit level.
The beneficial effects of the utility model are：Mandrel is connected by rolling bearing with calibrated mount, you can ensure calibrated mount around
Mandrel flexible rotating, and can ensure the centre of gyration of calibrated mount and the axiality of mandrel；Calibrated mount is provided with tubular type spirit level, when
Keyseat center alignment instrument is swung around workpiece spindle, when tubular type spirit level is horizontal, the axle center of workpiece spindle and the axle of main shaft
The heart overlaps, more objective directly easily to observe centering result.
Brief description of the drawings
The utility model is made with reference to the accompanying drawings and detailed description and being described in further detail.
Fig. 1 is structural representation of the present utility model.
Wherein：1st, mandrel, 2, calibrated mount, 3, rolling bearing, 4, spirit level.
Embodiment
In order to deepen to understanding of the present utility model, the utility model is made below in conjunction with embodiment and accompanying drawing further
It is described in detail, the embodiment is only used for explaining the utility model, does not form the restriction to the scope of protection of the utility model.
As shown in figure 1, the utility model mainly teaches a kind of keyseat center alignment instrument, including calibrated mount 2, mandrel 1,
Rolling bearing 3 and spirit level 4, spirit level 4 are connected to the upper reference plane of calibrated mount 2, and spirit level 4 is tubular type spirit level, by tradition
It is empirical be to knife, more precisely to swivel with the science type of spirit level level-off；The lower reference plane of calibrated mount 2 is presented V
Font, the vertex of the lower reference plane of calibrated mount 2 is in circular arc, and calibrated mount 2 is provided with rolling bearing 3, and rolling bearing 3 is located at water
Immediately below quasi- device 4, mandrel 1 is connected by rolling bearing 3 with calibrated mount 2, you can guarantee calibrated mount 2 is around the flexible rotating of mandrel 1, again
It can guarantee that the centre of gyration of calibrated mount 2 and the axiality of mandrel 1.The handle of keyseat center alignment instrument is clamped during use with three-jaw
Portion, the angle contact surface of calibrated mount 2 rest on workpiece spindle it is cylindrical on, keyseat center alignment instrument can be swung around workpiece spindle, when
When tubular type spirit level is horizontal, the axle center of workpiece spindle and the axis coinciding of main shaft are more objective directly easily to observe centering
As a result.
Above-described embodiment only illustrative principle of the present utility model, and the embodiment that part uses, for ability
The technical staff in domain designs similar technical scheme under the inspiration of technical solutions of the utility model, and reaches above-mentioned technology
Effect, belong to the scope of protection of the utility model.
