Description

The two-dimensional measurement servicing unit

The utility model relates to a kind of two-dimensional measurement servicing unit, and is particularly related to a kind of fixedly two-dimensional measurement servicing unit of plastic of being convenient to.

General measuring system, its same surface level that a bit must remain on above measuring table, this can be realized by the levelling pedestal.And the substrate that is placed on the surveying instrument on the measuring table also must remain on the same surface level with the plane (preposition face) of facing Measuring Object, after treating that total system has been fixed, an absolute reference coordinate system is just arranged so that the data recording when measuring to be provided.

The retaining element of traditional two-dimensional measurement, but usually all be to utilize the stationarity on object both sides and clamp tested object with clip, after the tested object to be clamped, just begin to utilize probe to do the action of measuring, promptly scan the point that will measure.The action that necessary work is earlier aimed at before the scanning, first point that first aligning will scan, the motion scan device is aimed at second point again, and mobile process must be carried out at same surface level.2 data are promptly known the size of distance before and after the record.Repeat these actions, write down all data, utilize these data to come the shape of object analysis.

Such fixed form has a shortcoming, and in other words: if clip has loosening situation, the data of then measuring have just produced the problem of correctness.And when having run into the very irregular object of shape, often must expend very many time and do fixing work, and situation about can't fix usually takes place.Therefore, this fixed form usually can have been incured loss through delay the progress of surveying work.

Therefore, the purpose of this utility model provides a kind of two-dimensional measurement servicing unit, to solve the changeable difficult fixing problem that can't measure because of the plastic shape that usually runs into when carrying out two-dimensional measurement.

For realizing above-mentioned and other purposes, the utility model provides a kind of two-dimensional measurement servicing unit, comprising: a vacuum extractor; A plurality of tubes; A plurality of associated lines, these associated lines are connected with an end of described vacuum extractor and described tube respectively; One stationary installation is in order to fixing described tube; And a plurality of adsorbent equipments, these adsorbent equipments are fitted to the other end of described tube respectively.

The utility model is owing to adopt the mode that vacuumizes to adsorb tested object, add bull pin retractable, the various external forms that can adapt to tested object, and universal sucker can more be guaranteed the adsorptive power to tested object, so the two-dimensional measurement servicing unit of utility model can have more the flexible various Measuring Object that are applied to.

For above-mentioned and other purposes, feature and advantage of the present utility model can be become apparent, a preferred embodiment cited below particularly, and conjunction with figs. are described in detail below, wherein

Fig. 1 is the side view of two-dimensional measurement servicing unit;

Fig. 2 is the stereographic map of two-dimensional measurement servicing unit;

Fig. 3 is the assembly drawing of bull pin and universal sucker.

Please refer to Fig. 1, it is the side view of the two-dimensional measurement servicing unit of the utility model one preferred embodiment.And please also refer to Fig. 2, Fig. 2 is the stereographic map of this two-dimensional measurement servicing unit.Wherein label 10 is air compressor, the 11st, air valve, the 12nd, associated line, the 13rd, connector, the 14th, stationary installation, the 15th, bull pin, the 16th, universal sucker, the 17th, tested object.

The effect of air compressor 10 is as the device that vacuumizes, and continues to extract out the air in associated line 12, bull pin 15 and the universal sucker 16, causes the vacuum in associated line 12, bull pin 15 and the universal sucker 16.And air valve 11 is used for controlling the flowing gas state between air compressor 10 and the associated line 12.Generally speaking, as long as this air compressor 10 can be controlled vacuum tightness in associated line 12, bull pin 15 and the universal sucker 16 well, the powerful suction that it produced is enough to fix the tested object 17 of difformity, size.

Bull pin 15, it is that tube by a hollow is constituted, be fitted in the stationary installation 14, can before and after telescopic moving separately, the front connects universal sucker 16, back and then is connected with associated line 12 with connector 13.Because the quantity of bull pin 15 is a lot, arrangement mode that can array is arranged in the stationary installation 14, can be decided by the profile of tested object 17 and use part bull pin 15.For move forward and backward, convenient fixing, bull pin 15 is fabricated to the rigid body of vertical bar shaped mostly, the bull pin 15 of profile is mutually more independent than being easier to because of parallel relation like this, separately elastic moving can not interact.In addition, 14 of bull pin 15 and stationary installations can be selected suitable retaining element for use, with the relative position of fixing bull pin 15 with stationary installation 14, and the relative position of just universal sucker 16 and stationary installation 14.

Connector 13 is used for connecting associated line 12 and bull pin 15.Measuring table 18 is planes of a complete level.The bottom surface of stationary installation 14 be flattened on fully measuring table 18 above, its purpose is used for supporting bull pin 15, makes that bull pin 15 is can be in stationary installation 14 elastic independently to be moved, with the tested object 17 of fixing various external forms.

Please refer to Fig. 3, Fig. 3 is the assembly drawing of bull pin 15 and universal sucker 16.

Wherein, universal sucker 16 is to hold tested object 17 with helping this two-dimensional measurement servicing unit.Its structure is the spherical elastic body of hollow semicircle, and any rotation direction of joint 19 energy that is connected with bull pin 15 is to adapt to tested object 17 characteristic that height rises and falls, normal direction differs.That is to say that the joint 19 with universal sucker 16 between bull pin 15 and the universal sucker 16 is connected to each other purpose of connecting: fix universal sucker 16 on the one hand, make universal sucker 16 that the space of rotation be arranged on the other hand.When the action of adsorbing, this universal sucker 16 utilizes the elastic property that itself has, and can adjust its shape along with tested object 17 changeable profiles, to reach the purpose that holds tested object 17 fully.Its structure can be born the powerful absorption affinity that inside and outside differential pressure produces, and its suction-operated then is to utilize the inside and outside differential pressure that vacuum state produced in the universal sucker 16 to hold tested object 17.Wait to fix after the tested object 17, can further measure action.

Though the utility model is illustrated in conjunction with a preferred embodiment, so it is not in order to qualification the utility model, for the industry, and under the situation that does not break away from spirit and scope of the present utility model, can do a little change and retouching.
