According to the parallelism detection apparatus, the reading mode of the indicating gauge is more direct, the error of a positioning reference is more accurately displayed, unnecessary error caused by artificial factors is avoided, in addition, the structure is simple, manufacture is convenient, the processing precision is easy to guarantee, a detection platform is established through a machine tool chuck surface, and the positioning precision is high.

Description

A kind of depth of parallelism pick-up unit

Technical field

The utility model relates to depth of parallelism detection range, be specially a kind of water pump in the depth of parallelism pick-up unit of big tube wall spare workpiece and lathe two reference fields on lathe.

Background technology

For the assembly precision that guarantees that water pump connects, the depth of parallelism of big tube wall spare two ends flange face requires very high in the water pump.

On general horizontal lathe, it is the depth of parallelism that directly detects lathe and workpiece two reference fields on the workpiece reference field with the mode of dial gauge measurement that the existing depth of parallelism detects, yet be difficult to directly measure with dial gauge at vertical lathe, peace position, four planes of common disposable car piece, again the manufactured reference field of workpiece is developed on the piece of peace position, utilize pit gauge with the chuck face be on the uniform four direction of reference measurement workpiece bottom height what, verify whether the location benchmark is accurately feasible, such detection mode error is very big, had a strong impact on the machining precision of part, finally reduced assembly precision, and the not high bearing heating that finally may cause of the assembly precision of water pump, problems such as guide bearing serious wear.

The utility model content

In order to improve the bearing accuracy of workpiece on lathe, the utility model aims to provide a kind of depth of parallelism pick-up unit, and this depth of parallelism pick-up unit is simple in structure, easy to operate, bearing accuracy is high.

To achieve these goals, the technical scheme that adopts of the utility model is:

A kind of depth of parallelism pick-up unit, its design feature be, comprises base, is contained on the base and the dial gauge that moves in any direction of base relatively by universal bindiny mechanism, and the gauge head of the detection workpiece depth of parallelism is housed on the described dial gauge.

Below be the technical scheme of further improvement of the utility model:

As a kind of concrete version, described universal bindiny mechanism comprises and being contained on the base and the slide block that moves in the horizontal direction of base relatively, is contained on the slide block connecting link that can move in perpendicular relative to slide block; One end of described connecting link is equipped with described dial gauge.

Further, have groove on the described base, described slide block bottom surface is provided with the fin that places in the groove and can move along groove.Certainly, also can have fin at described base, described slide block bottom surface is provided with the groove that places on the fin and can move along fin.

Specific to embodiment of the present utility model, described workpiece be water pump in the flange at big tube wall spare two ends, described gauge head contacts with the bottom surface of the flange of vertical layout.

By said structure, the utility model discloses a kind of pick-up unit of when processing the baseplane and making reference field lathe reference field depth of parallelism size being measured that is used in, comprise slide block and base and connecting link and dial gauge, develop on described slide block and described seating plane opposite, described slide block fin and described base groove adopt clearance fit, described connecting link is connected with cage bolt, and described dial gauge gauge head contacts with the workpiece reference plane.The utility model is used general measurer dial gauge, and make two slide blocks that the depth of parallelism is very high, the base of magnetic force gauge stand is removed, directly connecting link is contained in the holder, the dial gauge gauge head contacts with the workpiece reference field, by the moving around of slide block, the numerical value of observing dial gauge shows to detect the depth of parallelism of workpiece location benchmark on uniform four direction.

The depth of parallelism described in the utility model refers to have the deviation on concavo-convex height relative ideal plane, and pick-up unit of the present utility model is the depth of parallelism size of measuring workpieces reference field and these two faces of lathe reference field.

Compared with prior art, the beneficial effects of the utility model are:

1, the utility model is more direct with the mode of dial gauge reading, shows the size of location fiducial error more accurately, has avoided the unnecessary error of being brought by human factor.

2, the utility model is simple in structure, and is easily manufactured, and machining precision also guarantees easily, builds detection platform by the machine chuck face, the bearing accuracy height.

In sum, the utility model be a kind of simple in structure, easy to operate, bearing accuracy is high, the depth of parallelism pick-up unit of the workpiece bottom of easy popularization.

Below in conjunction with drawings and Examples the utility model is further elaborated.
