Description
Technical field
The utility model relates to a kind of large-scale lathe revolving meber beat centering auxiliary tools, belong to machining equipment technology
Field.
Background technique
Between machine extra bus, large-scale lathe operator needs the beat for measuring each portion using aligning method to ask before work pieces process
Whether topic, detection workpiece blank size meet the processing dimension requirement of drawing.Workpiece is revolution forging, and rounded, forging is being forged
It is easy to appear all kinds of problems such as crackle, shovel hole, outer circle decentraction, the irregular, workpiece bows of outer circular shape during making.
Beat refers to that revolving meber is once loaded in rotary course in lathe, and a certain cross-sections surfaces of workpiece are away from centre of gyration highest
The difference of point and minimum point is beat value of the revolving meber at this.
Traditional workpiece beat aligning method is the actual look situation according to workpiece blank, and operator utilizes scriber and steel
Plate ruler measures the beat numerical value of workpiece.During centering, scriber pitch of centers is the position contour with workpiece centre height,
In outer circle diameter on direction, scriber looks for a critical localisation with workpiece almost zero contact, and operator holds steel in workpiece rotation
Board foot, one end directly contact forging, and another end in contact scriber is top, steel ruler radial numerical difference mobile during workpiece rotation
Value is the beat numerical value of workpiece.
Above-mentioned workpiece beat aligning method has the following problems:
(1) during centering, the steel ruler moment is close to workpiece blank surface, and detecting steel ruler with workpiece is that line contacts, in blank
Under the dimpled state of outer circle, it is high point contact that steel ruler is contacted with workpiece, can not detect the depth of pit, therefore cannot be really anti-
Reflect workpiece pit situation；
(2) workpiece needs to rotate when measuring, and needs people directly to contact with workpiece when being measured with scriber with Steel Ruler, there is peace
Full hidden danger；
(3) during centering, workpiece is rotary motion, operator need during the inspection process high and low position and
The direction Shi Jilu and beat numerical value, this measurement method are affected by human factors larger, even if repeated multiple times measurement, cannot still protect
Demonstrate,prove the accuracy of measurement data.
Utility model content
The utility model aim is to provide a kind of large-scale lathe revolving meber beat centering auxiliary tool, can accurately measure
Beat numerical value of workpiece during centering, solves the problems, such as background technique.
The technical solution of the utility model is:
A kind of large size lathe revolving meber beat centering auxiliary tool, includes detection contact, mandril, positioning pin, hollow silk plug
One, sleeve, spring, hollow silk plug two and scale, the detection contact include bearing holder (housing, cover), pin shaft, bearing spider and bearing, bearing
In bearing holder (housing, cover), bearing is rotatably connected on bearing spider clearance fit by pin shaft, one end of mandril and bearing spider screw thread
The other end of connection, mandril is equipped with scale, and sleeve covers on mandril, spring is equipped in sleeve, the both ends of sleeve are equipped with and mandril
The hollow silk plug one and hollow silk plug two matched, scale is fixed on sleeve.
Positioning pin is equipped between the hollow silk plug one and mandril, to prevent mandril from rotating.
The hollow silk plug one and hollow silk plug two are connect with bush whorl respectively.
The mandril is equipped with the limit disk of compressed spring, and limit disk and mandril are in integral structure.
One end that the mandril is threadedly coupled with bearing spider is equipped with nut, for locking bearing spider.
The utility model is used, in use, sleeve is loaded on lathe saddle first, adjustment bearing spider touches detection
The axis of bearing in head is parallel with axis of workpiece, locking nut, fixing bearing support, and makes the bearing holder (housing, cover) in detection contact
It is close to workpiece surface；Then rotational workpieces one week, due to the variation of the excircle of workpiece surface radius of gyration, the rotation of workpiece makes to detect
Contact drives mandril to move linearly, and the difference of the maxima and minima of mandril linear movement is exactly the beat numerical value of blank.
The beneficial effects of the utility model are:
(1) this auxiliary tool is fixed on lathe saddle, easy for installation, stable, and by spring compression, can be quick, quasi-
Beat numerical value of true measurement workpiece during centering；
(2) it can directly be contacted to avoid worker with turning of work piece in use, the person of worker can be effectively ensured
Safety；
(3) real time data is provided during centering, avoids repeated measurement, adjusts repeatedly, improve centering working efficiency.
