The boring of pincers worker at present at first is to utilize manual line, and center-punching is holed with boring apparatuss such as bench drill, vertical drills then.Owing to use the hand control positional precision, so the pitch-row precision is low, general pitch-row precision is ± 0.2mm about,, can only process less than ± 0.06mm as if the pitch-row error requirements with jig borer.
The purpose of this utility model be for pincers worker obtain a kind of still utilize without jig borer low precision equipment such as common bench drill, vertical drill just can be fast, the low cost equiment of precision drilling.
The utility model mainly contains X, the Building Y mark system of vernier caliper type and drill bit is carried out the center identification display system composition of detection of dynamic.
The X of vernier caliper type, Building Y mark system structural representation are seen accompanying drawing 1, it by X main scale (4) with X vernier (3) that can move relative to X main scale (4) and Y main scale (1) with can form with respect to the Y vernier (5) that Y main scale (1) moves.X vernier (3) is connected with screw with Y vernier (5), and X main scale (4) is vertical mutually with Y main scale (1), and X main scale micro-adjusting mechanism (2) is made directions X and Y direction displacement microcall with Y main scale micro-adjusting mechanism (6).When X vernier and Y main scale moved, its displacement can be read from the scale value of main scale and vernier, and reading method is identical with vernier caliper.
Identification display system in center partly is made up of detection head, identification display, power pack three.
This machine general assembly synoptic diagram is seen accompanying drawing 4, the two ends of coordinate system X main scale (4) are separately fixed at the last plane of connector (21) both sides, identification display (19) and power pack (22) are separately fixed at connector (21) both sides, and detection head (20) is installed in the end of Y main scale (1).

When diameter is the centre drill insertion detection head centre frame endoporus of φ 7, the voltage of often unidirectional two photosensitive tubes output does not wait, so slight mobile bit location, two photosensitive tube output voltages of directions X and Y direction are equated respectively, measure centre drill axial line and detection head edge reference field distance X this moment

0The check point coordinate that is called this detection head, this coordinate values should be measured And and be labeled on the detection head before dispatching from the factory.
When reality is holed, when diameter is the centre drill insertion detection head centre frame endoporus of φ 7, the drill bit axial line often departs from its check point, unidirectional two photosensitive tube output voltages are not waited, for example, when drill bit departs from check point and makes progress, top light beam is lived morely with regard to drilled first speed, and the drilled first speed of following light beam is lived a little lessly, so the voltage that the voltage of top photosensitive tube output is exported less than following photosensitive tube, the two just has difference voltage output, be made as positive difference voltage, otherwise, drill bit downward bias from the time, output negative difference voltage.In like manner, when drill bit when left and right directions departs from check point, difference voltage output is also arranged.The size of difference voltage has reflected that the drill bit axial line departs from the degree of check point, and the symbol of difference voltage has reflected that drill bit departs from the direction of check point, therefore detects the size and the polarity of difference voltage and knows that promptly drill bit departs from the size and the direction of check point.
Because the widely different commentaries on classics precision of low precision boring apparatus such as common bench drill, vertical drill are low, therefore carrying out position probing under the drill bit static situation will produce very mistake, take the method for detection of dynamic for this this equipment, promptly under drill bit rotation situation, the widely different rotating shaft heart of drill bit line position is detected.Electrochemical capacitor C

4Exactly for the signal voltage filtering owing to the AC signal that the drill bit diameter run-out causes, making the output difference voltage only is the direct current signal of reflection axis of rotation line position.
Because the difference signal of detection head output is less, amplify so send into the differential amplifier circuit of identification display.
