Abstract
The utility model discloses a top plate for a device special for a long axis drawing process. One side of the top plate is fixed with another part for the device special for the drawing process, namely a flange plate; and the top plate has the function of fixing a bearing in the flange plate. The bearing in the flange plate on the side is in interference fit with a pointed cone on a lathe frame tailstock, so that the whole device special for the drawing process is fixed on the movable lathe frame tailstock. The other side of the flange plate is fixed with a chuck for clamping a long axis; and the flange plate connects the chuck and the lathe tailstock together, and the whole long axis to be processed is always positioned in the horizontally straightened state in the processing. Therefore, high processing accuracy is achieved. After a tool is arranged on the lathe tailstock, the tool is not needed to be moved and cannot influence the processing of other similar procedures. The clamped parts at two ends of the long axis are process heads, and are removed after the processing is finished, so the device special for the drawing process can respectively process the long axis in coarse, intermediate and refined procedures.
Description
Technical field
The utility model relates to machining equipment technology field, particularly relates to a kind of top board that is used for major axis processing drawing process isolated plant.
Background technology
Major axis processing is a difficult point in the machining.By the processing experience, usually the ratio of axial length and the diameter of axle is called major axis greater than 20 axle.Because the longaxones parts flexibility is big, poor rigidity.During cutting, because the radially amount of deflection that centrifugal force produced of axle deadweight, and the process system generation systems that lathe-anchor clamps-cutter constitutes vibrates.These factors all influence the machining accuracy of major axis.
Traditional axle processing and loading clamp mode is: Double Tops point clamping or two chuck mode clamping.These two kinds of installation way make processed axle be in an extruded state, and the axle body section upwards easily produces flexural deformation at the diameter of axle.As shown in Figure 1.
This clamping technology is little for draw ratio, axial length is short or the bigger axle class of shaft run-out tolerance can adopt.
The utility model content
Technical problem to be solved in the utility model is in the above-mentioned prior art clamping technology, it is yielding to be in the state of being squeezed during the major axis processing and loading clamp, thereby influences the problem of machining accuracy, and has proposed a kind of new processing technology, be drawing process, as shown in Figure 2.Major axis drawing process special tooling, being will be original " a traditional axle processing and loading clamp is---Double Tops point clamping or two chuck mode clamping ", and mode is improved, adopt " stretched fixation technology ", that is: Zhou a end is fixed in the spindle end of lathe, and the other end applies clamping (clamping) state of certain pulling force.The utility model is exactly the top board of this kind drawing process isolated plant, and the utility model makes major axis to be processed be in the horizontal stretch state, can guarantee the machining accuracy of major axis preferably.
The technical problem that the utility model requires to solve can be achieved through the following technical solutions:
A kind of top board that is used for major axis processing drawing process isolated plant, described top board has the end that is oblate bar shape and in oblate cylinder one side, the other end with the cylinder projection of oblate cylinder coaxial line, described top board centre is a through hole, is evenly equipped with screwed hole on the oblate cylinder circumference outside the cylinder projection.
Screwed hole on the described oblate cylinder is 4.
The cylinder convex side of described top board cooperates with another parts ring flange of drawing process isolated plant, and the cylinder projection injects in the bearing chamber at ring flange center; On the top board on screwed hole pitch-row facing each other and the ring flange corresponding screwed hole apart from consistent, the diameter of top board upper screwed hole is than the big 0.5mm of diameter of the screwed hole that matches with it on the ring flange, the diameter of cylinder projection is than little 0.5 mm of bearing chamber diameter at ring flange center, and the thickness of cylinder projection adds that bearing chamber inner bearing thickness is than the big 0.2mm of the bearing chamber degree of depth.
The utlity model has following characteristics:, can make the whole work in-process of processed major axis be in " level is stretching " state all the time by major axis stretching frock clamping.Help obtaining good machining accuracy like this.Frock need not to move after being installed on the lathe tailstock seat.Do not influence other similar operation processing yet.The part that is held at major axis two ends is technique head (to be processed remove) to size, thus special frock can process respectively major axis slightly, in, the Seiko preface.

The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
This drawing process is applicable to that the processing draw ratio is 20～40 major axis.Top board is selected 45 steel for use, carries out modifier treatment, to strengthen its working strength.
As Fig. 4, shown in Figure 5, top board comprises oblate cylinder 1 and with oblate cylinder 1 coaxial line and be positioned at the cylinder projection 2 of oblate cylinder 1 one sides, the top board centre is a through hole 3, is evenly equipped with four screwed holes 4 on outer oblate cylinder 1 circumference of cylinder projection 2.
At first assemble the drawing process isolated plant, installation diagram as shown in Figure 6, the bearing 6 of in the bearing chamber 5 of ring flange, packing into, bearing 6 is interference fit (H6/s5 or H7/t6 or H8/t7) with the bearing chamber 5 of ring flange, bearing 6 is embedded in the bearing chamber 5 of ring flange, inject the cylinder of top board projection 2 in the bearing chambers 5 afterwards and withstand on the bearing 6, with first group of screw 7 ring flange and top board are fixed at last.Fixing by top board and first group of screw 7, make bearing 6 be in fixing state, non-migration.
After the drawing process isolated plant assembles, pointed cone on the lathe tailstock tailstock 8 is inserted in the centre bore of the through hole at top board centers and bearing 5, (not shown pointed cone 8 cooperates with roof hole) as shown in Figure 7, pointed cone 8 is interference fit (H6/s5 or H7/t6 or H8/t7) with bearing 5, thereby whole drawing process isolated plant is fixed on the lathe tailstock tailstock.
With second group of four screw 9 that the chuck 10 of ring flange in the drawing process isolated plant and clamping major axis is fixing again, as shown in Figure 7.
After above-mentioned steps was finished, clamping major axis 11 was fixed in an end of major axis 11 on the spindle chuck 12 of lathe, and the other end is fixed on the chuck 10, as shown in Figure 3.
At last, the past passing that moves to right of the tailstock tailstock of lathe, and locking.Make major axis 11 integral body be in " level is stretching " state.
More than show and described basic principle, principal character and the advantage of the present utility model of utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
