Description
Technical field
The utility model relates to a kind of internal diameter pick-up unit.Be the internal diameter automatic tester that is used for measuring circular diameter in the tubular object specifically.
Background technology
At mechanical processing industry, often need the interior circular diameter of tubular object is measured.At present, the common method that is used for measuring tubular object internal diameter is, utilizes a telescopic ruler to adopt manual mode of operation to measure repeatedly in the tubular object, draws the internal diameter mean value of tubular object from measurement result repeatedly.Though utilize this method can record the interior circular diameter of tubular object, owing to be to adopt manual mode of operation, not only measuring result error is big, precision is low, and can't record the home position and the ovality of tubular object.Again because what utilize that scalable ruler measures employing is manual operations, time-consuming, effort, work efficiency is lower.
The utility model content
Problem to be solved in the utility model provides a kind of internal diameter automatic tester.Utilize this internal diameter automatic tester that the tubular object is measured, not only measuring accuracy height, high efficiency, and can record the home position and the ovality of tubular object.
For addressing the above problem, the utility model is taked following scheme:
Internal diameter automatic tester of the present utility model is characterized in containing base and backstay.Base wherein is tabular, and the lower end of backstay is fixed therein the heart, and the top and bottom of backstay and base are perpendicular.There is the revolution sleeve backstay outside, is rotatable shape between revolution sleeve and backstay and cooperates.Rotary motor is arranged on the base, be connected to worm screw on the output shaft of rotary motor.Revolution sleeve lower end excircle is to being evenly equipped with the teeth groove that is used to form worm gear, and said worm screw and this teeth groove mesh together.Revolution sleeve upper end is with positioning seat, and respectively there is a displacement transducer both sides of positioning seat, and this two displacement transducer all is on same the diameter line of positioning seat.
Take such scheme, have the following advantages:
Because the utility model internal diameter automatic tester contains base and backstay, the lower end of backstay is fixed therein the heart, and the top and bottom of backstay and base are perpendicular; The backstay outside has revolution sleeve and the two to be rotatable shape cooperation.Rotary motor is arranged on the base, be connected to worm screw on the output shaft of rotary motor.Revolution sleeve lower end excircle is to being evenly equipped with the teeth groove that is used to form worm gear, and said worm screw and this teeth groove mesh together.Revolution sleeve upper end has positioning seat, the both sides of positioning seat that a displacement transducer is respectively arranged, and this two displacement transducer all is on same the diameter line of positioning seat.During work, under the driving of rotary motor, can measure its internal diameter at any axial location of tubular object.
Owing on the base rotary motor is arranged, be connected to worm screw on the output shaft of rotary motor again.Revolution sleeve lower end excircle is to being evenly equipped with the teeth groove that is used to form worm gear, and said worm screw and this teeth groove mesh together.Drive the rotation of revolution sleeve by rotary motor by worm and gear during work.Simultaneously, can measure the angle orientation of revolving shaft, go out corresponding to the result under each orientation by two displacement sensors that are installed in revolution sleeve upper end again by between backstay and revolution sleeve, the angular light photoelectric coder being set.The angle position at the minimax extreme value place that measures corresponding to two displacement transducers under a certain angle, it is exactly the position at tested tubular article diameters place, two extreme value sums are exactly the interior circular diameter of tested tubular object, and half of two extreme value differences is exactly the departure of detector and tested tubular object home position.
Therefore, any position that the utility model can be in the tubular object is measured the internal diameter of tubular object, and can be obtained accurate internal diameter size and home position.Simultaneously, can also measure home position.
Again on the one hand,, not only can improve measuring accuracy, also can increase work efficiency because whole measuring process does not need manual operations.
