Description

Inner hole fluted shaft direction dimension measuring implement
Technical field
The present invention relates to the measuring appliance of mechanical component, especially inner hole fluted shaft direction dimension measuring implement.
Background technology
Design has annular groove in now in the hole of some mechanical component, and the width dimensions of groove and groove can't be finished with ordinary measring tool to the measurement of the size of interior hole end surface, and particularly the little groove of width is accurately measured its axial dimension, and it is just bigger to measure difficulty.
Summary of the invention
The purpose of this invention is to provide a kind of inner hole fluted shaft direction dimension measuring implement, can measure the axial accurate dimension of groove in the endoporus convenient, reliably.
The technical solution adopted for the present invention to solve the technical problems is: the ball gauge head that employing can be put into hole slot is fixed on an end of slip measuring staff, axially motion in the endoporus of slip measuring staff measuring of hole end surface in abutting against, the both sides of ball gauge head are close to the both sides of groove respectively.Make gauge head withstand on two numerical value of the corresponding demonstration of dial gauge of the slip measuring staff other end, the size when the ball gauge head is close to groove one end can be measured on measurer, calculates the physical size of endoporus groove width by known ball gauge head size.Inner hole fluted shaft direction dimension measuring implement is made up of ball gauge head, screw, measuring, handle, spring washer, slip measuring staff, bolt, dial gauge, opening sleeve and high-head knurling screw.The ball gauge head is contained in an end of slip measuring staff, the slip measuring staff is contained in and is clearance fit in the endoporus of measuring, the axial groove that handle passes measuring is contained on the slip measuring staff with the double-screw bolt of its front end, dial gauge is contained in the small end of measuring, the gauge head of dial gauge withstands on the end that the slip measuring staff is not adorned the ball gauge head, and high-head knurling screw is contained in the screw of measuring correspondence and can the slip measuring staff be fixed in the needs position.During measurement, holding measuring with one puts into the ball gauge head groove of workpiece hole and makes the measuring large end face be close to the measured workpiece outer end of hole, hold handle with another and make the ball gauge head be close to the both sides of groove respectively, withstand on the slip measuring staff and do not adorn the dial gauge of ball gauge head one end and also show two numerical value respectively.Just calculate the width dimensions of groove in the workpiece hole according to the size of ball gauge head.Under the cooperation of high-head knurling screw, can measure the size of ball gauge head according to the numerical value that dial gauge shows, thereby obtain the axial dimension of groove to the interior hole end surface of workpiece to the measuring body large end face with calibrated bolck or measurement slide calliper rule.
The advantage of this inner hole fluted shaft direction dimension measuring implement is: can measure the width dimensions of groove in the workpiece endoporus and the axial location size that groove arrives interior hole end surface fast and accurately.Design of Measuring Tools is reasonable, makes simply, and cost is low.

Embodiment
Referring to accompanying drawing 1, inner hole fluted shaft direction dimension measuring implement is made up of ball gauge head 1, screw 2, measuring 3, handle 4, spring washer 5, slip measuring staff 6, bolt 7, dial gauge 8, opening sleeve 9 and high-head knurling screw 10.Its double-screw bolt of ball gauge head 1 usefulness is contained in the screw vertical and crossing with slip measuring staff 6 axial lines of an end of slip measuring staff 6 with screw 2 lockings (seeing accompanying drawing 4).Slip measuring staff 6 is contained in to cooperate in the endoporus of measuring 3 and is H7/g6,0.01 millimeter of the large end face that measuring is used to the measure pair endoporus squareness tolerance that cooperates with the slip measuring staff.The axial groove that handle 4 passes measuring 3 is contained on the slip measuring staff 6 with the double-screw bolt of its front end, the double-screw bolt that is handle 4 its front ends of usefulness is tightened in the screw vertical and crossing with measuring staff 6 axial lines that slide by spring washer 5, and spring washer 5 is pressed on the flat end face of slip measuring staff 6 screw reams.Dial gauge 8 is fixing by the Kong Zhongyong bolt 7 that opening sleeve 9 is contained in measuring 3 small ends, avoids directly withstanding dial gauge 8 with bolt the distortion that cylinder causes is installed.The gauge head of dial gauge 8 withstands on the end that slip measuring staff 6 is not adorned ball gauge head 1, and high-head knurling screw 10 is contained in the screw of measuring 3 correspondences.Can be behind gage measuring, the numerical value of pressing dial gauge 8 indications is fixing with slip measuring staff 6 with high-head knurling screw 10 so that by measure ball gauge head 1 draw to the size of measuring 3 large end faces in hole slot arrive the axial dimension of interior hole end surface.In order to improve measurer serviceable life, ball gauge head 1 adopts the manufacturing of high-quality steel, thermal treatment 55~60HRC, and slip measuring staff 6 adopts the manufacturing of high-quality steel, thermal treatment 50~55HRC.Be convenient to observe the large end face of measuring 3 prune both sides and groove milling (seeing accompanying drawing 2) in the middle of the rectangular both sides that keep in order to measure.
Measurer using method: hold measuring 3 with one and make ball gauge head 1 put into the groove that to survey workpiece 11 endoporus, make measuring 3 large end faces be close to outer end of hole in the measured workpiece 11, hold handle 4 with another and make ball gauge head 1 be close to the outside of groove, dial gauge 8 shows first numerical value c.Hold handle 4 with another and make ball gauge head 1 be close to the inner edge of groove groove, dial gauge 8 shows second numerical value d.The records of values of dial gauge 8 twice demonstration is got off.Measurer is taken out, adjust the position of slip measuring staff 6 in measuring 3 endoporus according to first numerical value c, it is fixing with slip measuring staff 6 promptly to tighten high-head knurling screw 10 when dial gauge 8 is indicated numerical value for c.Measure end faces to lean on into size, this size to ball gauge head 1 be exactly the size a that workpiece 11 interior hole end surfaces are arrived in the outside of groove with measuring kind of calliper measuring 3.If the ball diameter of ball gauge head 1 is r, the width b=c-d+r of groove then.Because it is lower to measure the measuring accuracy of slide calliper rule, the calibrated bolck that can make by the theoretical value of the outside of the groove size a of hole end surfaces in the workpiece 11, being clipped in measuring 3 measures between end face and ball gauge head 1 bulb, with the check and correction of the pointer of the dial gauge on the measurer 8 is 0, the size a of the outside that numerical value c, the d that dial gauge 8 shows during according to gage measuring and the ball diameter r of ball gauge head 1 accurately calculate the width dimensions b of groove and groove hole end surface in the workpiece.
