When the precise guide screw median diameter jumpiness detector is operated, both ends of the guide screw are supported inside V-shaped valleys of the V-shaped pedestals and the measuring head leans against the bottom of a screw tooth of the guide screw; when the guide screw is rotated, movement in the axial direction of the guide screw is performed on the measuring head; the difference value of reading variation of the dial indicator is the median diameter jumpiness amount; the median diameter jumpiness value and the coaxiality of the guide screw can be measured in any axial direction; and the precise guide screw median diameter jumpiness detector can be used in various machine tool processing industries which require precise guide screws for transmission.
Description
Technical field
The utility model relates to a kind of measuring appliance, particularly a kind of measuring appliance that beat in the middle footpath of accurate screw mandrel and right alignment detects.
Background technology
On existing multiple lathe, need to use screw mandrel to carry out transmission, the precision of screw mandrel will directly have influence on the machining precision of product, therefore, detection to screw mandrel is absolutely necessary, wherein, beat in the middle footpath of screw mandrel and the right alignment detection is wherein important one, in the prior art, screw mandrel adds man-hour being clamped on the lathe, can be in any fixed position of lathe fixing dial gauge, the feeler lever of dial gauge is vertically conflicted on screw mandrel, rotary screw rod can detect the screw mandrel middle footpath jerk value and the right alignment of a certain position in the axial direction, still simultaneously, after screw mandrel leaves original processing unit (plant), then can not detect effectively accurately again.
The utility model content
The purpose of this utility model provides in a kind of accurate screw mandrel the footpath and beats and the right alignment detector, and it can be at any time detected the middle footpath jerk value and the right alignment of the optional position on the screw mandrel.
The purpose of this utility model is achieved in that footpath glitch detection instrument in the accurate screw mandrel, comprise fuselage, the same horizontal line of fuselage is provided with two V-arrangement bearings, the upper horizontal of described V-arrangement bearing is provided with a rolling linear guide, cooperate with rolling linear guide and to be provided with slide block, be fixed with a dial gauge and measuring mechanism on the described slide block, described measuring mechanism comprises housing, uprightly be provided with a sounding rod in the housing, the sounding rod lower end is provided with the measuring head that can conflict on screw mandrel to be measured, being axially arranged with spring on the sounding rod and between the housing, conflicts in the sounding rod upper end in the feeler lever lower end of dial gauge.
During the utility model work, in the V-shaped groove of V-arrangement bearing, therefore, the screw axis edema with the heart involved that is bearing on the V-arrangement bearing is flat, parallels with the rolling linear guide running orbit with the screw mandrel two supports, and the measuring head on the sounding rod is conflicted in the thread groove of screw mandrel.When the middle footpath of screw mandrel changes, spring produces sounding rod and moves axially, correspondingly, make the corresponding reading that produces on the dial gauge, when screw mandrel rotates, can produce the variation of reading, the amount that during difference between the some readings after it changes is beat in the footpath, half of its difference is right alignment, moving slider, and wherein footpath jitter values and right alignment are measured in the optional position in the axial direction, compared with prior art, the utility model can detect the middle footpath jerk value and the right alignment of optional position on the screw mandrel, and it is easy to detect, can verify the precision of screw mandrel; The machine tooling industry that can be used for the accurate screw mandrel transmission of various needs.
Be the convenient position of adjusting dial gauge, described dial gauge is connected with slide block through contiguous block, uprightly is provided with kidney slot on the contiguous block, and the standing screw through passing kidney slot between contiguous block and the slide block fixes.Unclamping the standing screw contiguous block can be along kidney slot direction slip certain distance, and like this, dial gauge can suitably move a certain distance, to adapt to the measurement of different-diameter axle.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is that the A of Fig. 1 is to view.
Wherein, 1 dial gauge, 2 contiguous blocks, 3 sounding rods, 4 springs, 5 housings, 6 measuring heads, 7 detected screw mandrels, 8 V-arrangement bearings, 9 fuselages, 10 kidney slots, 11 annular knurl handwheels
Embodiment
As figure, footpath glitch detection instrument in the accurate screw mandrel, comprise fuselage 9, fuselage 9 same horizontal lines are provided with two V-arrangement bearings 8, the upper horizontal of described V-arrangement bearing 8 is provided with a rolling linear guide, cooperate with rolling linear guide and to be provided with slide block, be fixed with a dial gauge 1 and a measuring mechanism on the described slide block, described measuring mechanism comprises housing 5, uprightly be provided with a sounding rod 3 in the housing 5, sounding rod 3 lower ends are provided with the measuring head in the screw thread 6 on screw mandrel to be measured of can conflicting, and are axially arranged with spring 4 on the sounding rod 3 and between the housing 5, conflict in sounding rod 3 upper ends in the feeler lever lower end of dial gauge 1.Be the convenient position of adjusting dial gauge 1, described dial gauge 1 is connected with slide block through contiguous block 2, uprightly is provided with kidney slot 10 on the contiguous block 2, and the standing screw through passing kidney slot 10 between contiguous block 2 and the slide block fixes.Unclamping standing screw contiguous block 2 can be along kidney slot 10 direction slip certain distance, and like this, dial gauge 1 can suitably move a certain distance, to adapt to the measurement of different-diameter axle.
During work, in the V-arrangement depression of V-arrangement bearing 8, the diameter at screw mandrel 7 two ends is identical with screw mandrel 7 two supports; When the screw mandrel two ends diameter of axle was inconsistent, the degree of depth of vee-block was adjusted in design, makes screw mandrel center line maintenance level.If the screw mandrel two ends are provided with center pit, can adopt conical sliding support, make screw mandrel center line level.Therefore, be bearing in the screw mandrel 7 axle center levels on the V-arrangement bearing 8, parallel with the running orbit of rolling linear guide, measuring head 6 is conflicted in the thread groove of screw mandrel, and at this moment, spring 4 produces sounding rod and moves axially, screw mandrel moves measuring head generation screw mandrel axis direction when rotation annular knurl handwheel 11 drives screw mandrel 7 rotations, when central footpath changes, make dial gauge 1 produce reading and change, the difference between the some readings after it changes is the amount of beating in middle footpath; Half of its difference is right alignment value error, and this method can detect the middle footpath jerk value and the right alignment of optional position on the screw mandrel, and it is easy to detect, can verify the precision of screw mandrel; The machine tooling industry that is used for the accurate screw mandrel transmission of various needs.
