Abstract
The invention belongs to a detecting appliance in the field of machining and provides a novel detecting device for thread hole to end surface verticality. The novel detecting device is mainly characterized in that one side of a fixed seat is fastened on the upper part of a rotary shaft; a rotary sleeve sleeves the lower part of the rotary shaft; a taper thread part is connected at the lower end of the rotary shaft; a measuring rod is arranged at one side of the lower end surface of a rotary disc of the rotary sleeve; the other side of the fixed seat is sleeved by a dial indicator; the conical tip at the lower end of the dial indicator is in contact with the upper end surface of the rotary disc; in measurement, the lower end of the rotary shaft is coupled with the thread hole of a workpiece; a measuring head of the measuring rod is in contact with the end surface of the rotary disc; the difference between a maximum number and a minimum number displayed on the dial indicator is the measured verticality. The novel detecting appliance provided by the invention has the advantages of convenience in use, good adaptability and accurate measurement.
Description
Technical field
The invention belongs to field of machining, relate to detection utensil, specifically face, a kind of Novel spiral pit opposite end testing apparatus for verticality.
Background technology
In mechanical processing process, in order to reach the respective performances index of sealing after Assurance component combination, to the threaded hole of workpiece and the verticality of threaded hole end face, propose very high requirement, verticality maximal value can not more than 0.06.
The method of existing detection workpiece threaded hole and threaded hole end face squareness mainly contains:
1, three-dimensional detects.The gauge head shape of three-dimensional is one spherical, when measuring threaded hole endoporus, needs to get eight measurement points, because the pitch of different screw thread is different, may get between crest or tooth, so just easily cause measurement inaccurate; For the occasion that precision prescribed is high, three-dimensional detects inapplicable.
2, clearance gauge detects.Adopt easy measurement column, try square, in addition clearance gauge measuring workpieces screw thread hole verticality, the detection data obtained are often inaccurate.
3, some are not easily moved or complex-shaped workpiece, frock can only be leaned on to ensure, the exact numerical values recited of screw thread hole verticality cannot be detected, affect the quality of product, cause some to lose to enterprise.
Measuring workpieces threaded hole and threaded hole end face squareness accurately, easily, ensure authenticity and the accuracy of measurement result, overcoming the defect that prior art exists, is a technical task of field of machining for a long time.
Technology contents
The object of the invention is to study face, a kind of Novel spiral pit opposite end testing apparatus for verticality, the verticality of workpiece threaded hole and threaded hole end face can be detected accurately and easily, ensure product quality further.
The technical solution used in the present invention is design face, a kind of Novel spiral pit opposite end testing apparatus for verticality, its structure comprises: holder, rotating shaft, measuring stick, its shaft top is fastened on side in holder by securing member, rotary sleeve is arranged with in the bottom of rotating shaft, taper thread part is connected with in rotating shaft lower end, the measuring stick that gauge head is cone is provided with in the side, rotating disc lower surface of rotary sleeve, opposite side in holder is fastened with copper sheathing, the table bar of dial gauge and rotating shaft walk abreast, wear and be located in copper sheathing, the table bar lower end of dial gauge is coniform, epiconus contacts with the upper surface of rotating disc, during use, the external thread of the taper thread part of rotating shaft lower end and the threaded hole phase close-coupled of measured workpiece, the centre of gyration of rotating shaft and the threaded hole center superposition of measured workpiece, the epiconus gauge head of measuring stick contacts with the threaded hole end face of measured workpiece.
In said structure, described in be connected to the taper thread part of rotating shaft lower end, adopt the taper thread part of the different size of removable flexible connection, to adapt to the workpiece detecting different thread pitch.
This pick-up unit of the present invention, it is the epiconus gauge head utilizing measuring stick, by the information sensed threaded hole and the threaded hole end face of measured workpiece, sense on dial gauge by the epiconus of rotary sleeve rotating disc upper surface and dial gauge table bar lower end, and then to records of values shown on dial gauge, calculating, obtain the verticality data of measured workpiece threaded hole double thread hole end surface.During measurement, after the epiconus gauge head of measuring stick contacts with the threaded hole end face of measured workpiece, the initial value of record dial gauge display, the rotating disc of rotation rotary sleeve one week, numerical value in record rotation process shown by dial gauge, find out maximal value wherein, minimum value, calculate the difference of maxima and minima, namely gained difference is measured workpiece threaded hole double thread hole end surface verticality numerical value.
Face, this Novel spiral pit opposite end of the present invention testing apparatus for verticality, compared with prior art, have easy to use, adaptability is good, and measurement result is accurate, effectively improves the remarkable advantage of workpiece product quality.Some are not easily moved or complex-shaped workpiece, and the workpiece of different threaded hole, also conveniently can detect threaded hole double thread hole end surface verticality.
Model machine is through repeatedly trying out, and no matter small workpiece or large workpiece, the vertical angle value of workpiece threaded hole double thread hole end surface is no more than 0.06 at most, meets correlated performance requirement, effectively improves the quality of product, significantly reduce cost allowance.
Accompanying drawing explanation
Fig. 1 represents the structural representation of face, a kind of Novel spiral pit opposite end of the present invention testing apparatus for verticality.
Embodiment
In conjunction with the accompanying drawings and embodiments, concrete structure of the present invention is further illustrated.
A kind of face, Novel spiral pit opposite end of the present invention testing apparatus for verticality embodiment, see Fig. 1, its structure comprises: holder 4, rotating shaft 7, measuring stick 1, dial gauge 5, copper sheathing 2, holding screw 3, 6, rotary sleeve 8, the top of its shaft 7 is fastened on side in holder 4 by holding screw 6, in the bottom of rotating shaft 7, cover has rotary sleeve 8, the taper thread part 7.1 of removable flexible connection is connected with in rotating shaft 7 lower end, being provided with gauge head in the side, rotating disc 8.1 lower surface of rotary sleeve is cone shape measuring stick 1, opposite side in holder 4 is ordered 3 by clamp screw and is fastened with copper sheathing 2, table bar and the rotating shaft 7 of dial gauge 5 walk abreast, be set in copper sheathing 2, the table bar lower end 5.1 of dial gauge 5 is in coniform, cone point contacts with the upper surface of rotating disc 8.1.During use, when large workpiece not easily moves, the taper thread part 7.1 of rotating shaft 7 lower end is screwed into threaded hole (omitting in figure) the phase close-coupled of measured workpiece, make the centre of gyration of rotating shaft 7 and the threaded hole end face center superposition of measured workpiece, the epiconus gauge head of measuring stick 1 contacts with the threaded hole section of measured workpiece.During measurement, when after the epiconus gauge head of measuring stick 1 and the threaded hole end contact of measured workpiece, the reading of display on record dial gauge 5, rotate rotating disc 8.1 1 weeks, the minimum and maximum reading of display on dial gauge 5 in record rotation process, maximum number in reading and minimum number are calculated difference, and namely institute's value is measured workpiece threaded hole double thread hole end surface verticality.
