Abstract
The utility model relates to an electronic gripper ruler used for measuring the outside dimension of an object. The division value of the electronic gripper ruler is 0.01 mm. The utility model mainly comprises a measuring arm, a measuring claw, a magnetic stripe ruler, a magnetic head, an electrical signal processing circuit, and an electrical signal display circuit. When the utility model is used for measuring, the expansion of the measuring arm causes the magnetic stripe ruler and the magnetic head connected with the measuring arm to move relatively, electrical potential is inducted on the coil of the magnetic head, and the electrical potential is amplified, processed, and displayed on a displayer. The signal can be output to a numerical control machine tool through a signal output interface, and the automatic working of the machine tool can be achieved. The utility model has the advantages of convenient operation and high measuring precision.
Description
The utility model relates to the metering of a kind of length, thickness and similar linear dimension, and it belongs to a kind of precision measuringtoll.
Employed measurer has vernier caliper in the prior art, vertification regulation JJG-92 referring to State Bureau of Technical Supervision's publication, this measurer has advantages such as simple structure, measurement range is big, price is low, but owing to structural reason, its precision can only reach 0.02 millimeter, another kind of measurer milscale, referring to the vertification regulation JJG21-86 that State Metrological Bureau publishes, its measuring accuracy is higher, but owing to adopt screw structure, use inconvenience, measuring speed is slow.
The purpose of this utility model provides a kind of mechanical measurement, the electronics gripper rule that electronics shows, and it had both had the convenience of vernier caliper measurement, had higher measuring accuracy again.
Below in conjunction with accompanying drawing 1 realization technical scheme of the present utility model is described: the utility model is by left gage beam 1, right gage beam 2, left side measuring claw 3, right measuring claw 4, meshing gear 5, magnetic stripe chi 6, magnetic head 7, signal input interface 8, signal output interface 9, amplifier 10, data processor 11, controller 12 and display 13 are formed, the A that it is characterized in that left gage beam 1, B, C is in a straight line, the D of right gage beam 2, E, F also is in a straight line, left-right symmetric, B point and E are point articulated on housing, also having a pair of on two gage beams is the fan-shaped meshing gear 5 in the center of circle with B point and E point, two gage beams can be that rotate synchronously symmetrically by means of meshing gear in the center of circle with B point and E point, the A end of left side gage beam 1 connects magnetic stripe chi 6, the D end of right gage beam 2 connects magnetic head 7, and magnetic stripe chi 6 is that the one side of relative magnetic head 7 on chi is coated with magnetic material 14.
During measurement, open left and right sides gage beam, clamp testee W by left and right two measuring claws, because the fulcrum B and the E of left and right gage beam fix, so 2 same to the inside moved further of A, D, therefore magnetic stripe chi 6 and magnetic head 7 relatively move, and produce induced potential at the coil II of magnetic head 7, handle the back demonstrates measured object W on display 13 diameter through amplifier 10, data processor 11.Controller 12 can make display 13 return zero at any time.Signal output interface 9 can be connected to numerically-controlled machine, realizes processing automatically.
The utility model compared with prior art has following advantage: 1, than vernier caliper measurement precision height, can reach 0.01 millimeter; 2, use and convenient reading than milscale; 3, can provide feedback signal to numerically-controlled machine, to realize automatic processing.
Description of drawings:
Fig. 1 is a structural representation of the present utility model, and left and right gage beam 1 and 2 is to have the metal material of certain thickness and width to make.The C of two gage beams and F and two measuring claws 3,4 adopt hinged.
Embodiment:
It is that 2 millimeters, width are that 10 millimeters corrosion resistant plate is made that the left and right sides of the present utility model gage beam adopts thickness, two arm symmetries, AB: BC (air line distance)=DE: EF (air line distance)=1: 10, when the measured object size increases by 1 millimeter, then A, D end moves 0.1 millimeter to the inside, its numeral shows by display, minimum magnetized area can be accomplished 0.000321 millimeter according to modern science and technology, getting minimum magnetized area in the present embodiment is 0.001 millimeter, that is to say that can measure scale division value is 0.01 millimeter workpiece.
