Abstract
The invention discloses a flexible fixture applicable to workpieces with irregular shapes. The flexible fixture is characterized by comprising at least two arc-shaped baffle plates which are bent toward a clamped workpiece; each arc-shaped baffle plate is covered with a flexible air bag; each arc-shaped baffle plate is provided with an air inlet and an air outlet which communicate with the corresponding flexible air bag; each air inlet is connected with an inflation pump; each air outlet is connected with an air outlet adjusting valve; the working surface, which is in contact with the workpiece, of each flexible air bag is provided with a pressure sensing sheet; the pressure sensing sheets, the inflation pumps and the air outlet adjusting valves are separately connected with a controller through wireless signals; and the controller determines whether the clamped workpiece is tightly clamped or not according to signals transmitted by the pressure sensing sheets and controls a clamping degree by adjusting the inflation pumps and the air outlet adjusting valves. By adopting the flexible fixture, the probability that a workpiece with high brittleness is damaged can be effectively reduced; and furthermore, for a workpiece with an irregular shape, the flexible air bags can effectively cling to the outer surface of the workpiece, so that the clamping degree is improved.
Description
Technical field
The present invention relates to a kind of fixture, particularly to a kind of flexible fixture suitable in workpiece in irregular shape.
Background technology
Having in prior art and a kind of workpiece carries out the fixture that horizontal direction is fixing, mainly include workbench and the baffle plate being positioned on workbench, baffle plate is driven by driving device, can movable workbench relatively, it is achieved Workpiece clamping or unclamp action.But in machinery production manufacture process; would ordinarily be encountered irregular workpiece and need to carry out the situation of Surface Machining process; for above-mentioned fixture; it mostly is hard between its work surface with workpiece to contact; workpiece higher for fragility, in irregular shape; this kind of fixture is easily caused held workpiece damage, reduces conforming product rate, affects production efficiency.
Summary of the invention
It is an object of the invention to overcome deficiency of the prior art, it is provided that a kind of flexible fixture suitable in workpiece in irregular shape, solve the technical problem of irregular piece-holder inconvenience in prior art.
For solving above-mentioned technical problem, the technical solution adopted in the present invention is: suitable in the flexible fixture of workpiece in irregular shape, including the curved baffle that at least two bends to held part, described curved baffle is all covered with flexible air-bag, described curved baffle offers the air inlet connected with flexible air-bag and venthole, described air inlet is connected with inflator pump, described venthole is connected with adjustment valve of giving vent to anger, the work surface that described flexible air-bag contacts with workpiece is provided with pressure sensitive sheet, described pressure sensitive sheet, inflator pump and adjustment valve of giving vent to anger are connected with controller wireless signal respectively；
The signal that controller transmits according to pressure sensitive sheet judges whether held part is clamped, by regulating inflator pump and governor valve control clamping degree of giving vent to anger.
Described curved baffle is provided with three, and three clamping plate surround circular distribution in the periphery of held part.
Described adjustment valve of giving vent to anger is the electromagnetic valve with wireless transport module.
Being additionally provided with baroceptor in described flexible air-bag, the air pressure that controller controls in flexible air-bag according to baroceptor is in safe air pressure range.
Being also associated with alarm on described controller, when flexible air-bag internal gas pressure exceedes maximum atmospheric pressure value or pressure sensitive sheet detects that pressure exceedes the maximum pressure value of setting or during lower than the pressure minimum set, alarm output is reported to the police.
Described flexible air-bag is for selecting latex material.
Compared with prior art, the present invention reachesBeneficial effectIt is: flexible air-bag is set on the clamping work surface of curved baffle, realizes flexible contact with held workpiece, it is possible to effectively reduce the impaired probability of workpiece that fragility is higher, additionally, for workpiece in irregular shape, flexible air-bag effectively can be fitted with outer surface of workpiece, improves clamping degree.
Accompanying drawing explanation
Fig. 1It it is the structural representation of the present inventionFigure。
In figure: 1, curved baffle；2, flexible air-bag；3, pressure sensitive sheet；4, inflator pump；5, give vent to anger adjustment valve；6, baroceptor.
Below in conjunction withAccompanying drawingThe invention will be further described.Following example are only for clearly illustrating technical scheme, and can not limit the scope of the invention with this.
Detailed description of the invention
Such as Fig. 1Shown in, it is adaptable to the flexible fixture of workpiece in irregular shape, including the curved baffle 1 bent to held part, curved baffle 1 at least should arrange two, as highly preferred embodiment of the present invention, curved baffle 1 arranges three, and three curved baffles 1 surround open circle.
Curved baffle 1 is all covered with flexible air-bag 2, curved baffle 1 is also opened simultaneously and run through air inlet and the venthole that curved baffle 1 is connected with flexible air-bag 2.Air inlet is connected with inflator pump 4, and venthole is connected with adjustment valve 4 of giving vent to anger, and adjustment valve 4 of giving vent to anger can be selected for being provided with the electromagnetic valve of wireless transport module, for carrying out radio communication with controller.In order to better control clamping degree, the work surface that flexible air-bag 2 contacts with workpiece is provided with pressure sensitive sheet 3, pressure sensitive sheet 3 and inflator pump 4 are connected with controller wireless signal respectively, the signal that controller transmits according to pressure sensitive sheet 3 judges whether held part is clamped, and controls clamping degree by regulating inflator pump 4 and adjustment valve 4 of giving vent to anger.
In order to flexible air-bag 2 is detected, it is prevented that air pressure is too high, being additionally provided with baroceptor 6 in flexible air-bag 2, controller controls the air pressure in flexible air-bag 2 according to baroceptor 6 and is in safe air pressure range.Being also associated with alarm on controller, when flexible air-bag 2 internal gas pressure exceedes maximum atmospheric pressure value or pressure sensitive sheet 3 detects that pressure exceedes the maximum pressure value of setting or during lower than the pressure minimum set, alarm output is reported to the police.Preferably, flexible air-bag 2 is for selecting latex material, and latex material can be degraded voluntarily, is beneficial to environmental protection.
The above is only the preferred embodiment of the present invention; it should be pointed out that, for those skilled in the art, under the premise without departing from the technology of the present invention principle; can also making some improvement and deformation, these improve and deformation also should be regarded as protection scope of the present invention.
