Abstract
The utility model relates to the field of the measurement of the columns of the hydraulic supports and cylinder barrel parts of various lifting jacks, particularly a measuring device for the axiality of a step-hole-structure cylinder barrel. The measuring device resolves the problems such as the inconvenience of selective examination, rigorous measurement conditions and the like, which exist in the prior on-machine-tool measuring method with dial gauge for the measurement of the axialities of the step-hole-structure cylinder barrels. The measuring device comprises a dial indicator and an installing seat for fixing the dial indicator. Two lugs are installed in parallel on the installing seat, a position-fixing block which can be installed between the two lugs is fixedly connected at the rear part of the dial indicator, and a fixing screw which can fix the position-fixing block between the two lugs is installed on one or either of the two lugs. The measuring device has a new and unique structure, good manufacturability, and good practical applicability. The measuring device does not requires special measurement conditions, and with the adoption of the measuring device, momentary selective examinations and measurements are convenient to carry out in the working place and the operation and the process are not affected.
Description
Technical field
The utility model relates to the fields of measurement of cylinder components in hydraulic support column and all kinds of lifting jack, specifically is a kind of stepped hole structural formula cylinder barrel coaxality measurement measurer.
Background technology
Hydraulic support is the important support apparatus of channel of coal mining working surface, and wherein, column and all kinds of lifting jack are the main executive components of hydraulic support, and the critical component-cylinder barrel of column and all kinds of lifting jack plays a part very important.
The cylinder barrel of hydraulic support column and all kinds of lifting jack is all stepped hole structural formula cylinder barrel, endoporus and the hole, seam position through finish turning processing that orienting sleeve is installed through roll extrusion that piston and piston rod are installed are arranged in its design, the version of this two holes right alignment is a kind of typical closely right alignment structure of a short slotted hole, this two hole must reach the right alignment of designing requirement when processing and manufacturing, if right alignment is bad, not only influence follow-up assembling, also can influence the sealing of seal element, cause column and lifting jack leakage, therefore more need to measure accurately the right alignment in two holes.And in production testing over the years, right alignment at this two hole adopts the detection mode of playing table with bed always, the detection mode of playing table with bed is a kind of comparatively accurate detection method, but have many weak points: 1, the reviewer will follow the tracks of parts constantly and machine situation, can not spot-check at any time; The change of dismounting benchmark detects with bed under the situation about must after workpiece processing is finished, not dismantle when 2, detecting, in case then can't detect again; 3, the processing progress that delays workpiece is operated a little conflict of generation with produced on-site and workman.
Summary of the invention
The utility model existing beaten the table detection mode with bed and is measured problems such as selective examination inconvenience that step pore structure formula cylinder barrel right alignment exists, testing conditions harshness in order to solve, and a kind of stepped hole structural formula cylinder barrel coaxality measurement measurer is provided.
The utility model is to adopt following technical scheme to realize: stepped hole structural formula cylinder barrel coaxality measurement measurer, comprise dial gauge, be used for fixing the mount pad of dial gauge, mount pad is provided with the two ear seats that be arranged in parallel, the afterbody of dial gauge is fixed with the maintenance piece that can place between the two ear seats, and two ear seats or wherein be equipped with the fastening bolt that the maintenance piece can be anchored between the two ear seats on the ear seat.
The bottom surface of mount pad is fixed with three contour legs, and distribution relation require to satisfy: guarantee the steady placement that mount pad can be in cylinder barrel; The effect of three contour legs is to determine a reference plane with 3, as measuring basis.
Measuring process is as follows:
1, measurer described in the utility model is placed the cylinder barrel internal surface of hole, as shown in Figure 3;
2, mount pad is placed the either direction of cylinder barrel slotted hole inside surface, the sounding rod of dial gauge then places the short internal surface of hole of cylinder barrel a bit simultaneously;
3, by adjusting the relative angle of maintenance piece, adjust the angle of inclination of dial gauge, see that the indicator variation makes the measuring head of dial gauge sounding rod push down short hole surface;
4, mobile gently mount pad sees that the dial gauge indicator changes the minimum point that finds this direction, the indicator zero clearing;
5, the cylinder barrel half-twist is measured once more, seen that indicator changes, determine the indicator reading of this direction minimum point, and record;
6, again with the cylinder barrel half-twist, measure for the third time, write down the indicator reading of this direction minimum point equally;
7, again with the cylinder barrel half-twist, carry out the 4th time and measure, write down the indicator reading of this direction minimum point equally;
8, the difference of the minimum and maximum reading of indicator then reflects the variable quantity of tested axis relative datum axial location in the four direction, is the coaxiality error in two holes.
To measure a certain cylinder barrel is example, indicator zero clearing for the first time, half-twist indicator reading for the second time is-0.02, half-twist indicator reading for the third time is 0.01, the 4th indicator reading of half-twist is 0.05, the coaxiality error in two holes is that full-scale reading 0.05 deducts least count-0.02 so, promptly obtains measurement result 0.07.
During measurement, because tested axis may occur in the space all directions the difference of datum axis, so except that four 90 ° of directions selecting 360 ° of full circle, also can select six or more multi-direction the measurement, when detecting to reflect the variable quantity of different directions comparatively exactly.
In addition,, can adjust the angle of inclination of dial gauge, adapting to two holes of different bench heights, thereby solve the big problem that product detects by the maintenance piece between rotation mount pad two ear seats.
Compared with prior art, no matter whether dismantle, whether benchmark change by workpiece for the utility model, can spot-check at any time at the scene, detects at any time; And do not influence operation processing, take their own roads, Each performs its own functions.Return middle cylinder barrel, the outer cylinder that factory needs the repetition measurement right alignment in addition at going wrong on the ore deposit, need not lathe centering benchmark again, solve easily and completely with regard to being able to; And along with the continuous rising of company's production, the quantity of the product of entrusting outward also is on the increase, outer inspection task amount also strengthens thereupon, when outer inspection personnel go out to check and accept, can carry measurer described in the utility model, at any time detect the quality of the outer committee of control easily product.
The utility model structure uniqueness, novelty, good manufacturability, easy and simple to handle, practical, no special detection condition is beneficial to the realization scene and spot-check at any time, detects at any time, and does not influence operation processing.
