Description
Technical field
The utility model relates to a kind of measurement mechanism, and particularly a kind of pipe tobacco apparatus for measuring thickness especially can be discerned the detection contact automatically and whether really touch the pipe tobacco upper surface.
Background technology
At present, known pipe tobacco apparatus for measuring thickness is made up of test axle, chi gate sensor, test contact and optoelectronic switch.When test contact contacts with measured object, the optoelectronic switch that is installed on the test contact detects material, and the chi gate sensor goes out the thickness of pipe tobacco according to the test point position calculation.General pipe tobacco apparatus for measuring thickness can not distinguish that indivedual pipe tobacco falsenesses are in the light or test contact really arrives at the pipe tobacco surface, causes difficulty to detection, causes misjudgment easily.
Summary of the invention
Can not distinguish the deficiency that a little pipe tobacco falseness is in the light in order to overcome existing pipe tobacco apparatus for measuring thickness, the utility model provides a kind of pipe tobacco apparatus for measuring thickness, and this pipe tobacco apparatus for measuring thickness can distinguish easily that a little pipe tobacco falseness is in the light or test contact really arrives at the pipe tobacco surface.Main shaft and countershaft rock the steady nothing of motion of main shaft and countershaft by corresponding linear bearing guiding, have improved measuring accuracy effectively.
The purpose of this utility model realizes by following structural measure: this pipe tobacco apparatus for measuring thickness comprises telescopic main shaft and is arranged on countershaft in the rack sleeve by the countershaft linear bearing, the countershaft lower end is stretched out sleeve and is connected with a plate-like and surveys contact, the diameter of surveying contact is greater than sleeve outer diameter, telescopic main shaft is arranged in the main shaft linear bearing, and power drive lower edge bearing shaft moves up and down outside, the main shaft linear bearing is fixed on the frame, be provided with locating part being arranged on the countershaft of sleeve, distance between locating part lower edge and the detection contact upper end edge is greater than the length of countershaft linear bearing, telescopic main shaft top is the ring mesa structure, on the Huan Tai upper surface, be oppositely arranged to be useful on and detect the photoelectric sensor whether countershaft leans out spindle collar platform upper surface, the probe part of chi gate sensor is fixed on the frame, and its chi grid are installed in the Huan Tai side of telescopic main shaft and extend vertically downward.
In the utility model, described photoelectric sensor is infrared slit photoelectric sensor.
The locating part that is located on the countershaft can be the spacing ring that is sleeved on the countershaft, also can be the spacer pin that is installed in the countershaft slit.
The technical solution of the utility model and test process are: the slit photoelectric sensor is installed above main shaft, and countershaft passes from spacing ring.The chi gate part of chi gate sensor is installed in the side of main shaft, and when main shaft moved up and down, the chi grid were followed main shaft and moved up and down, and chi gate sensor probe part is fixed on the fuselage motionless.When test contact contacts tested pipe tobacco surface, test contact is subjected to thrust upwards, produce slight relative motion between secondary test axle and the main test axle, the slit photoelectric sensor detects countershaft and leans out main shaft (initial position is the optical axis that the countershaft upper surface just is lower than the slit photoelectric sensor), judges that with this test contact has contacted tested pipe tobacco surface.This moment the chi gate sensor the probe part position of measuring the chi grid, reach the purpose of measuring pipe tobacco thickness.
The test philosophy of the utility model foundation is as follows: the main shaft reference position is positioned at the test surfaces top, keep certain distance with tested surface, when the test beginning, test surfaces does not have material, and drive unit drives main shaft and does rectilinear motion downwards, when test contact contact measured surface, test contact is subjected to thrust upwards, produce slight relative motion between secondary test axle and the main test axle, the slit photoelectric sensor detects countershaft and leans out main shaft, judges that with this test contact has contacted measured surface.This moment the chi gate sensor the probe part position of measuring the chi grid, this position is the null position of test surfaces; Drive unit drive test contact resets and puts initial position.Then tested pipe tobacco is placed on the measured position, starts drive unit once more, drive unit drive shaft and then drive test contact are done rectilinear motion downwards.When test contact contacts tested pipe tobacco surface, the anchorage force that the gravity of test contact and pipe tobacco show reaches balance, test contact is subjected to balance thrust upwards, produce slight relative motion between secondary test axle and the main test axle, the slit photoelectric sensor detects countershaft and leans out main shaft, judges that with this test contact has contacted tested pipe tobacco surface.This moment the chi gate sensor the probe part position of measuring the chi grid, the measured value of the measured value of current chi gate sensor when adopting zero poor is the thickness of tested pipe tobacco.Survey amplitude that the material countershaft upwards leans out main shaft much at one because adopt zero-sum, twice measured value subtracts each other also just to have eliminated by countershaft and leans out the caused absolute error of main shaft, reaches the purpose of measuring pipe tobacco thickness.
The beneficial effects of the utility model are: can be when test measured object thickness, and distinguishing easily is that a little pipe tobacco falseness is in the light or test contact really arrives at the pipe tobacco surface, and reasonable in design, simple in structure, easy to use.
