A kind of A.C. contactor connection locator

Technical field

The utility model is related to a kind of vibration measurement with laser tool, more particularly to a kind of A.C. contactor connection locator.

Background technology

A.C. contactor is used for frequently switching on and cutting off major loop or the electronic device of large capacity control circuit as a kind of, It is widely used in controlling motor and other electrical loads.The performance of A.C. contactor is mainly shown as insulation resistance, is attracted Release voltage and vibration noise size.Wherein, the important indicator of evaluation A.C. contactor properties of product has shaking for A.C. contactor Dynamic amplitude and noise size.Therefore, every A.C. contactor is required for carrying out noise monitoring, whether to judge it before manufacture Meet noise criteria.

Some domestic scholars have made the producing cause of A.C. contactor running noises detailed analysis, are taken from technique A variety of methods reduce its running noises, and take a variety of methods from technique to reduce its running noises.A part of scholar's choosing The measurement that its running noises is realized using acceleration transducer is selected, but still belongs to a kind of contact measurement method.In order to more Add it is objective, quick, comprehensively detect ac contactor running noises, better detection mode still use contactless measurement It is detected.Vibration measurement with laser method is a kind of preferable non-contact measurement.

The utility model is intended to provide a kind of A.C. contactor positioning device suitable for vibration measurement with laser method, it can be achieved that workpiece Quick positioning, and surface is quickly connect by electric connection contacts with external power supply.

Utility model content

The purpose of the utility model is to overcome the deficiencies of the prior art, provide a kind of A.C. contactor connection positioning dress Put, can it is more objective, quick, comprehensively detect ac contactor running noises, have very big application and popularization value.

Technical solution is used by the utility model solves its technical problem：A kind of A.C. contactor connection positioning dress It puts, it is characterised in that：Including pedestal, thin cylinder, fulcrum bearing, bearing nail and clamp body；The fulcrum bearing is convexly equipped in the bottom Seating face, and preliminary limiting is formed to workpiece in the horizontal direction；

The pedestal is equipped with guide rail in the horizontal direction, and the fixture gate is equipped in the side of the extending direction of guide rail, should Fixture gate is followed closely along bearing used for positioning is laterally equipped with；Guide rail described in drive lower edge of the clamp body in the thin cylinder Movement, and the clamp body is pushed further to be limited by press-fit, and to workpiece with the fixture gate；The clamp body Surface be equipped with several electric connection contacts, which is connected with external power supply, and in clamp body and fixture gear It is electrically connected when plate presses press-fit with workpiece surface formation, workpiece surface is made to be connect with external power supply and is electrically connected.

As a preferred embodiment, the end of several electric connection contacts is equipped with elastic buffer structure with elastic telescopic, and make Clamp body can be formed with the workpiece of different surfaces shape and is electrically connected.

As a preferred embodiment, the bottom of the clamp body is equipped with the sliding seat being slidably matched with the guide rail, and clamp body Top surface and side use acrylic insulating materials.

As a preferred embodiment, the fulcrum bearing shares two, and the top of two fulcrum bearings is equipped with counterface.

As a preferred embodiment, the thin cylinder is fixedly installed in the pedestal by a cylinder block.

The beneficial effects of the utility model are：

1st, the fixation of workpiece is divided into Primary Location and further two stages of positioning, workpiece is followed closely by rest pad and bearing It is tentatively limited, then the clamp body and fixture gate that are driven by thin cylinder are further limited；Ensure the more of workpiece A degree of freedom is defined simultaneously, on the one hand, is conducive to eliminate the clamping error in measuring, on the other hand, can be minimized Collision of the workpiece in clamping process between clamping tool, prevents workpiece to be damaged.

2nd, by setting acrylic insulating materials in clamp body, ensure to can guarantee top while electric connection contacts correctly connect Face and side can form insulation system.

3rd, the end of electric connection contacts can elastic telescopic, the workpiece of different surfaces shape can be adapted to, and can guarantee electrical connection The stability that contact is connected with workpiece.

The utility model is described in further detail with reference to the accompanying drawings and embodiments；But a kind of friendship of the utility model Stream contactor connection locator is not limited to embodiment.
