Abstract

The utility model relates to a work piece top circle precision detector comprising at least one V-shaped dynamic measuring device; one display device is connected with the V-shaped dynamic measuring device and the V-shaped dynamic measuring device comprises a V-shaped locating device; the V-shaped locating device is equipped with an airway inside; one end of the airway is communicated with the display device by an air hose and the other end is communicated with measuring air holes equipped on both internal sides of a V-shaped groove. The work piece is put on the V-shaped measuring device in the process of measurement and the measuring value of the detected work piece will be displayed on a buoy air gage by a buoy; operators can directly judge the diameter, size, roundness, cylindricity, taper and elliptical point of the work piece with naked eyes; with the utility model, the detecting efficiency is greatly increased; the measuring result is accurate and reliable; the measuring precision can reach 0.001mm. The utility model greatly increases the detecting efficiency and ensures the product quality of work piece; in this way, the credit of the company and the assembly quality of users can be guaranteed to a great extent; the utility model has excellent social and economic benefits and is easy for application and dissemination.

Description

The accurate detecting device of a kind of excircle of workpiece

Technical field

The accurate detecting device of a kind of excircle of workpiece of the utility model belongs to and detects excircle of workpiece physical dimension and form and position tolerance technical field.

Background technology

At present, the mode that excircle of workpiece is detected adopts dial gauge or clock gauge to position measurement mostly, this kind mode requires very high to operator's operative technique, and the operator will estimate four to five dial gauges or clock gauges simultaneously, in addition, during detection, the diameter of measured workpiece is also perpendicular with the contact of dial gauge or clock gauge.More loaded down with trivial details when work begins to calibrate dial gauge or clock gauge, measurement result has certain error, and it is not very directly perceived that circularity, tapering detect.Operator's mode of operation also has certain error, and the precision of measurement is not very high, adopts this kind mode labour intensity bigger, and detection efficiency is lower.

The utility model content

The purpose of this utility model is to provide a kind of excircle of workpiece accurate detecting device, with big raising measuring accuracy, reduces labour intensity, improves detection efficiency.

To achieve these goals, the technical solution of the utility model is to have adopted the accurate detecting device of a kind of excircle of workpiece, comprise at least one V-type air measuring device, interconnected a display device with the V-type air measuring device, described V-type air measuring device comprises the V-type locating device, in the V-type locating device airway is set, airway one end is connected with display device by a gas rope, and the other end is communicated with measurement pore on being arranged on V-type groove two inboard inclined-planes.

Described V-type groove two inboard inclined-planes are made up of high-abrasive material.

Described display device is a float type air-gauge or intelligent electric minor light beam measuring instrument.

Described airway is connected with the connecting thread Guan Yuqi rope of base by being communicated with the V-type locating device.

Because excircle of workpiece accurate detector of the present utility model is combined with display device by the V-type air measuring device, according to cylindrical pneumatic measuring instrument operation requirement, workpiece is carried out not contact measurement, measurement result, accurately and reliably, measuring accuracy reaches 0.001mm, in addition, also can be used for detecting excircle of workpiece diameter dimension, circularity, cylindricity, tapering etc.During measurement, workpiece is placed on the V-type measurement mechanism, the measured value that detects workpiece shows by buoy on the float type air-gauge, operator's range estimation just can be judged diameter dimension size, circularity, cylindricity, tapering, the elliptical point of workpiece very intuitively, the utility model has increased substantially detection efficiency, has guaranteed the product quality of workpiece, and the prestige on quality of company and user's assembly quality are had very big guarantee, have good social benefit and economic benefit, be easy to apply.

Embodiment

As Fig. 1, shown in Figure 2, the accurate detecting device of excircle of workpiece of the present utility model, comprise three V-type air measuring devices, interconnected a float type air-gauge 11 with the V-type air measuring device, described V-type air measuring device comprises V-type locating device 5, base 6, leg 7, airway 4 is set in V-type locating device 5, airway 4 one ends of three V-type air measuring devices are connected with float type air-gauge 11 by a gas rope 12 respectively, airway 4 is connected with gas rope 12 with the connecting thread pipe 8 of base 6 by being communicated with V-type locating device 5, the other end of airway 4 is communicated with measurement pore 1 on being arranged on V-type groove two inboard inclined-planes, V-type groove two inboard inclined-planes are provided with high-abrasive material 2, and V-type locating device 5 is fixed together by gib screw 9 with base 6.

During work: at first will connect V-type air measuring device and float type pneumatic measuring instrument 11 by gas rope 12, and whether detect each parts position intact.The standard component of measured workpiece is put on the V-type locating device 5, the standard component outside surface contacts with high-abrasive material 2, do not contact with other parts, measure the diameter place of pore 1 alignment criteria part, in conjunction with float type air-gauge 11, the tolerance of measuring is indicated by buoy 10 on float type air-gauge 11, calibrated the buoy measuring accuracy; Then, standard component is taken off, workpiece is placed on the V-type locating device 5, workpiece rotates on V-type locating device 5, reads measured value on float type air-gauge 11, simultaneously range estimation, just can judge circularity, cylindricity, tapering, the elliptical point of workpiece very intuitively, device of the present utility model has increased substantially detection efficiency, measurement result accurately and reliably, measuring accuracy reaches 0.001mm.

It should be noted last that: above embodiment is the unrestricted the technical solution of the utility model in order to explanation only, although the utility model is had been described in detail with reference to the foregoing description, those of ordinary skill in the art is to be understood that: still can make amendment or be equal to replacement the utility model, and not breaking away from any modification or partial replacement of spirit and scope of the present utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
