Brief description of the drawings
Fig. 1 is the structural representation of installation of sensors fixture in an embodiment of the present invention;
Fig. 2 is the structural representation of installation of sensors fixture in the another kind of embodiment of the present invention.
Embodiment
By reference to the accompanying drawings the present invention is described in further detail below by embodiment.
Embodiment mono-
Please refer to Fig. 1, this enforcement provides a kind of installation of sensors fixture, comprises web member 101, cushion block 103 and sucker 104.
Web member 101 tops are provided with fixed mechanism 102, and fixed mechanism 102 is for being fixedly connected with sensor 100.The top of cushion block 103 is fixedly connected on web member 101 bottoms.Sucker 104 sealed holdings are between web member 101 and cushion block 103, and cushion block 103 is positioned at the inner chamber of sucker 104.
For the installation of sensors fixture better the present embodiment being provided describes, in Fig. 1, sensor 100 is illustrated, with illustrate installation of sensors fixture in use with the assembly relation of sensor 100.Wherein, sensor 100 can be wireless senser, can be also wired sensor, and during for wired sensor, sensor 100 outputs to the signal sensing in instrument by signal wire.
Concrete, fixed mechanism 102 can be for protruding from the screw thread fixed mechanism at web member 101 tops.For example: the grub screw that one end is fixed on web member 101, the other end protrudes from web member 101 tops.Should be appreciated that sensor 100 is corresponding has a thread groove mating with grub screw.In other embodiments, can be also that sensor 100 has protruding screw thread fixed mechanism, on web member 101, there is the thread groove mating with this screw thread fixed mechanism.
Cushion block 103 is threaded connection and is fixed on web member 101 bottoms.Concrete, can be that the thread protrusion arranging on cushion block 103 is fastened on the thread groove of web member 101 bottoms, can be also the thread protrusion that web member 101 bottoms arrange is fastened on the groove at cushion block 103 tops.
The bottom end face of cushion block 103 be positioned at sucker 104 inside, with sucker 104 open end predeterminable range places.In the time that sucker 104 is adsorbed on object under test surface, the bottom of cushion block 103 and object under test surface close contact, sensor 100 is by web member 101 and cushion block 103 is indirect and object under test is rigidly connected, thus the stability while ensureing test.200 surfaces that are object under test in Fig. 1.
Conventionally, the xsect of web member 101, cushion block 103 and sucker 104 is circular.The outline of cushion block 103 is step-like, and for example cushion block 103 is a round platform.In other embodiments, the shape of cross section of web member 101, cushion block 103 and sucker 104 can be square or other are irregularly shaped.
The material of sucker 104 and web member 101 is the key factors that determine installation of sensors fixture sealing property and measuring stability.For meeting the requirement to sucker oil resistance in actual production process, in the present embodiment, the material of sucker 104 adopts polyurethane, nitrile rubber or contains polyvinyl.Because the principle of design of installation of sensors fixture is that quality is little, rigidity is large and damping is large, therefore, in the present embodiment, the material of web member 101 and cushion block 103 adopts aluminium.In other embodiments, in installation of sensors fixture, the material of web member 101, cushion block 103 and sucker 104 can be selected according to concrete environment for use.
In the embodiment of the present invention, when the bottom of each parts refers to that installation of sensors fixture is arranged on object under test, point to one end of object under test, top refers to one end of object under test dorsad.
The installation of sensors fixture that the present embodiment provides, can be fixed to the fixture that is placed with sensor on object under test fast by sucker 104, meanwhile, is also convenient to after being completed, fixture be taken off.In addition, after fixture is adsorbed on object under test by sucker 104, cushion block 103 contacts with object under test, and sensor and object under test, for being rigidly connected, have ensured the stability of test.The sectional fixture that the present embodiment provides does not limit for the selection of material, need not consider the problem of testee material, and its scope of application is wider.
Embodiment bis-
Please refer to Fig. 2, this enforcement provides another kind of installation of sensors fixture, and on the basis of the installation of sensors fixture providing based on above-described embodiment one, its difference is:
Cushion block 103 inside have a cavity 201, and web member 101 side openings are provided with and connect pore 202, and cavity 201 is communicated with the inner chamber that connects pore 202, sucker 104; Installation of sensors fixture also comprises vacuum pump 203, vacuum pump 203 by trachea 204 with connect together with pore 202 is sealedly connected and fixed.
Preferably, installation of sensors fixture also comprises the T-valve 205 being arranged on trachea 204, two valve ports of T-valve 205 respectively with connect pore 204 and vacuum pump 203 is communicated with, on another valve port, be provided with blowdown valve 206.
Using in the fixing process of sucker 104, sucker 104 vacuum pressure in sucker 104 with the laminating degree direct influence that is adsorbed object under test surface, if laminating degree is excessively poor, the vacuum tightness of sucker 104 is difficult for keeping, just do not reach the object of absorption object under test.In using vacuum cup 104, perfect condition is that in sucker 104, the one side of cushion block 103 contact measured objects is smooth, and seals after laminating, is beneficial to vacuum cup 104 and clenches object under test surface.But crawled object under test surface does not possess such ideal conditions conventionally, object under test surface conventionally has pore or is coarse injustice, and these factors directly affect the laminating degree on sucker 104 and object under test surface.In the situation that fitting state difference with object under test surface, sucker 104 will there is leakage phenomenon.So the present embodiment uses high performance minipump 203, extract out within the shortest time leaking the gas of coming in.In to installation of sensors jig Design process, the structure of cushion block 103 need to guarantee and sucker 104 close contacts, also can be good with object under test Surface Contact, also need to keep the stability of top sensor 100 simultaneously.
The installation of sensors fixture that the present embodiment provides is in the time of concrete use, first open minipump 203, then the end face of sucker is attached to rapidly to the surface of object under test, air in sucker 104 is pumped, form certain vacuum tightness, now, the pressure of sucker 104 inside is lower than the pressure of sucker 104 outsides, cushion block 103 in sucker 104 is attached to tightly the surface of object under test under the effect of external pressure, sensor 100 and cushion block 103, for being rigidly connected, can be realized the test of fast and stable.After test data record, open blowdown valve 206, sucker 104 inside and external atmosphere pressure are connected, and sucker 104 can depart from object under test surface, thereby can measure fast and effectively data.
The installation of sensors fixture that the present embodiment provides can be realized Quick Measurement, be departed from fast the object of object under test, and it is simple in structure, easy to operate.Require in shorter environment of test duration at some, the especially operation on streamline, opens minipump 203, can fast sucker 104 be attached to object under test surface, opens blowdown valve 206, and sucker 104 departs from object under test surface.Wherein, trachea 204 and sucker 104 can be used as consumptive material and use, and can change, with cost-saving after its loss.
Above content is in conjunction with concrete embodiment further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, do not departing under the prerequisite of inventive concept of the present invention, can also make some simple deduction or replace.
