Abstract
The utility model discloses an use pneumatic measuring principle's a pneumatic inside diameter measurement device. Motion and upper end cover connecting rod looks rigid couplings such as outside arm, drive sphere or conical surface gauge head along measured workpiece axis direction motion, because measured workpiece and sphere or conical surface gauge head can not guaranteed with one heart totally, there is position error, the surface elder generation and the contact of measured workpiece top edge of sphere or conical surface gauge head, because the effect of flexible pole and the sphere or the conical surface, sphere or conical surface gauge head can carry out the motion of by a small margin along with the position difference of measured workpiece, adjustment position error, make sphere or conical surface gauge head can get into the measured workpiece smoothly. Gas gets into measuring device through fast plug, because the upper end cover fills up and the press the sealing cooperation of measured workpiece upper end through sealing, gas can only be through the outflow of the circumferential weld between sphere or conical surface gauge head and the measured workpiece internal diameter. When the measured workpiece internal diameter changed, circumferential weld area between it and sphere or the conical surface gauge head was also along with the change, and flow area changes promptly, and the change of measured workpiece external diameter is changed into the undulant signal of atmospheric pressure, the processing and the air -gauge unanimity of follow -up signal. This pneumatic inside diameter measurement device not only can make sphere or conical surface gauge head get into the measured workpiece smoothly in the measurement process, eliminates the gauge head and block the phenomenon in the measured workpiece easily, makes pneumatic inside diameter measurement device and manipulator combine together simultaneously, and realization mechanical automation measurement has changed traditional pneumatic inside diameter measurement device's structure moreover, more reliable and stable of messenger measuring result.
Description
Technical field
The utility model relates to a kind of measurement mechanism, particularly a kind of pneumatic inner diameter measuring device.
Background technology
In batch production process or in production line, as long as there is stable source of the gas, just pneumatic gauging can be realized.The features such as it is high that pneumatic gauging has measuring accuracy, and measuring process is stablized, easy realization.Air measuring device can be used to directly to measure the size of measured workpiece, geometric configuration and position deviation.Air measuring device is through in fact the modification of the nozzle-baffle mechanism of accurate Calculation, and the pressure characteristic of nozzle-baffle mechanism and discharge characteristic are the bases of design air measuring device.When selecting air measuring device, first to carry out concrete analysis and calculation to pneumatic measuring system, selecting air-gauge, making its scale range meet the measurement requirement of measured workpiece; Its secondary working range determining air measuring device, is operated in linearity range to make air-gauge; Finally also to determine the minimum of scaffold tower and maximal clearance, and design the concrete size of measurement mechanism on this basis.But, at present when using pneumatic inner diameter measuring device, because the gap between pneumatic inner diameter measuring device and workpiece is very little, during measurement, plug jet not easily puts into workpiece, when using mechanical automation to measure, then more easily occur that measurement mechanism is stuck in the phenomenon in measured workpiece, causes the damage on measurement mechanism or measured workpiece surface.In addition pneumatic inner diameter measuring device now must be provided with multiple nozzle bore, is distributed on the different position of measurement mechanism, could measures accurately workpiece.So current pneumatic inner diameter measurement is used for artificial streamline and measures.The mode of workman's manual measurement, make labor strength large, production efficiency is low.
Summary of the invention
Not easily measured workpiece is put in order to overcome existing pneumatic inner diameter measuring device, when using mechanical automation to measure, measurement mechanism is easily stuck in the deficiency in measured workpiece, the utility model provides a kind of pneumatic inner diameter measuring device, this pneumatic inner diameter measuring device can not only enter measured workpiece smoothly and measure in measuring process, elimination measurement mechanism easily blocks phenomenon within the workpiece, make pneumatic inner diameter measuring device and mechanical arm combine simultaneously, realize mechanical automation to measure, and change the structure of traditional, pneumatic inner diameter measuring device nozzle-baffle mechanism, make measurement result more reliable and stable.
The utility model solves the technical scheme that its technical matters adopts: utilize pneumatic gauging principle, change the structure of traditional, pneumatic inner diameter measuring device, adopt spheric probe, make spheric probe or form circumferential weld between circular conical surface gauge head and measured workpiece internal diameter, to meet the requirement of pneumatic inner diameter measurement to gap, the spheric probe of measurement mechanism or circular conical surface gauge head and rods (as rubber rods) pass through thread connection, the upper end cover of rods and measurement mechanism passes through thread connection, measurement mechanism upper end cover is connected with motions such as mechanical arms, in order to realize driving measurement mechanism motion, upper end cover place is provided with quick connector, the circumferential weld that gas can be entered spheric probe by quick connector or be formed between circular conical surface gauge head and testee, the motions such as mechanical arm, measurement mechanism is driven to move downward above workpiece by upper end cover and rods, generally measured workpiece and measurement mechanism can not ensure completely with one heart, location error, the spheric probe of measurement mechanism or circular conical surface gauge head first contact with measured workpiece, due to the effect of rods and sphere or the conical surface, spherical or conical surface gauge head can because the effect opposite piece of contact force carries out movement by a small margin, to adjust site error, spherical or conical surface gauge head is enable to enter measured workpiece smoothly, measurement mechanism upper end cover and measured workpiece are contacted by packing washer, prevent gas from flowing out, air after voltage stabilizing enters measurement mechanism cavity through quick connector, then cavity is flowed out by spherical or conical surface gauge head and the formation of measured workpiece internal diameter circumferential weld, when measured workpiece internal diameter changes, circumferential weld area between it and spherical or conical surface gauge head is also along with change, namely flow area changes, the change of measured workpiece internal diameter is converted into air pressure fluctuation signal, and the process of follow-up signal is consistent with air-gauge.The technical program, according to pneumatic gauging principle, can make the automation equipment such as air measuring device and mechanical arm combine, measure fast and accurately the internal diameter of workpiece; If spherical or conical surface gauge head are designed to carry out axially-movable along with the relative measured workpiece of measurement mechanism with rods, circumferential weld will be in the diverse location of measured workpiece, then can realize the measurement to technical parameters such as measured workpiece cylindricities.
The beneficial effects of the utility model are, solve when using pneumatic gauging, the problem that traditional, pneumatic inner diameter measuring device and measured workpiece easily block, the motion such as air measuring device and mechanical arm is combined, realize mechanization, automatic measurement, change the structure of typical measuring arrangements simultaneously, make gas circuit structure more simple and reliable, measurement result more quick and precisely, is easy to safeguard and use.
