The invention discloses a floating tooling, which comprises a transition shaft, a fixture body, a positioning disk and a positioning shaft, the transition shaft is connected with a machine tool, the fixture body is connected with the transition shaft, the positioning disk is mounted on the fixture body, one end of the positioning shaft is connected with the positioning disk, the other end of the positioning shaft is in positioning contact with a workpiece, the upper end of the fixture body is provided with a circle of groove, filling parts are placed in the groove, and the positioning disk is in contact with the filling parts and can move as the filling parts move. By arranging the groove and the filling parts placed in the groove, the floating of the positioning disk is realized, thereby the workpiece can float to be aligned alone when a tool for machining a plunger sleeve enters the bore of the workpiece, consequently, the machining precision of the bore in the plunger sleeve is increased, the reject rate is decreased, the efficiency of production is increased, and the manufacturing cost is reduced.
Description
Technical field
The present invention relates to auto parts and components field, particularly relate to a kind of float type frock of slightly cutting with scissors processing for plunger bushing mesopore.
Background technology
Existing plunger bushing Fixture Design is due to can not free floating, on hinge top gem of a girdle-pendant machine, to there is plunger bushing mesopore circularity excessive in processing, subsequent fine is finally caused to add mesopore circularity over tolerance in man-hour, and the phenomenon often having processing not get up at the bottom of aperture or hole, the phenomenon such as cause that plunger bushing is scrapped, have to solve this problem by strengthening operation allowance, but this method has had a strong impact on working (machining) efficiency, and processing cost is improved for this reason.
Therefore, need a kind of new technical scheme to solve the problem.
Summary of the invention
Goal of the invention: provide one can improve plunger bushing mesopore machining accuracy, rate of reducing the number of rejects and seconds, enhances productivity, reduces the float type frock of manufacturing cost.
Technical scheme: a kind of float type frock, comprise the locating shaft that the transition axis be connected with lathe, the clamp body be connected with transition axis, the positioning disk being installed on clamp body and one end are connected to positioning disk, the other end of locating shaft and absorption surface are located, the upper end of described clamp body is provided with a circle groove, be placed with full part in groove, described positioning disk contacts with full part and moves along with the motion of full part.
Beneficial effect: float type tool structure of the present invention is simple, and can improve plunger bushing mesopore machining accuracy, rate of reducing the number of rejects and seconds, enhances productivity, reduces manufacturing cost.
Accompanying drawing explanation
Fig. 1 is the sectional view of float type frock.
Detailed description of the invention
It is the sectional view of the float type frock of slightly cutting with scissors processing for plunger bushing mesopore shown in Fig. 1.
Float type frock comprises the transition axis 1 be connected with lathe, the clamp body 2 be connected with transition axis 1, is installed on the positioning disk 3 above clamp body 2 and is connected to the locating shaft 4 of positioning disk 3.One end of locating shaft 4 is connected to positioning disk 3, the other end and contacts with workpiece 5 and locate.
Lathe has the hole that 8 uniform, each hole and main shaft have higher axiality, and the lower end of transition axis 1 and the hole of lathe have good matched in clearance, and the upper end of transition axis 1 and the endoporus of clamp body 2 have good matched in clearance precision.Indirectly like this ensure that clamp body 2 and main shaft have good axiality.
The upper end of clamp body 2 is provided with a circle spherical groove 6, is placed with full part 7 (D7 diameter steel ball) in groove 6, and positioning disk 3 contacts with full part 7 and moves along with the motion of full part 7.Clamp body 2 is the most critical parts of whole float type frock, when rolling along with the rolling of full part 7 in groove 6 after positioning disk 3 puts clamp body 2.The amount of floating of frock is then limited by the aperture of positioning disk 3 lower end outside diameter and clamp body 2, and the aperture 1mm larger than the outside diameter of positioning disk 3 of clamp body 2, therefore there has been the flying height of monolateral 0.5mm in workpiece process.
The lower end of locating shaft 4 and the endoporus of positioning disk 3 have higher matched in clearance precision, indirectly ensure that the positioning precision of workpiece.The upper end cylindrical of locating shaft 4 and upper surface contact with workpiece 5 endoporus and inner face and locate.Good coaxial accuracy is there has been like this at processed process mesopore and machine tool chief axis.
Clamp body 2 is also provided with 4 equally distributed screwed holes, and positioning disk 3 to be positioned at above clamp body 2 and to be provided with the anti-rotating hole corresponding with this screwed hole.Clamp body 2 is linked together with positioning disk 3 by attachment screw 10 (M10 soket head cap screw) and is locked by locking nut 11.Attachment screw 10 enters into four anti-rotating holes of positioning disk 3 through part 10 screwed hole, when not affecting positioning disk 3 and floating by locking nut 11 by screw lock, thus prevent screw in process because frock vibrations get loose.That is by the setting of attachment screw 10, both ensure that positioning disk 3 rotated in process, and made again positioning disk 3 and clamp body 2 be connected together, prevent positioning disk from deviating from clamp body 10.
The below of clamp body 2 is also provided with transition connecting plate 8.Transition connecting plate 8 is provided with two open slots, and clamp body 2 is connected with transition connecting plate 8 by attachment screw 9 (M8 soket head cap screw), and whole frock is indirectly compressed on machine tool body by trapezoidal screw again.
Positioning disk 3 is connected with the transition press plate 12 preventing locating shaft 4 axial float and deviate from.The effect of transition press plate 12 ensures that locating shaft 4 can not axial float and deviating from.Transition press plate 12 is connected on positioning disk 3 by attachment screw 13.Transition press plate 12 is also connected with compression plate 14, has the groove conformed to plunger bushing profile in the middle of pressure strip 14, and has clockwise 30 degree of interior swivelling chutes rotated.Plunger bushing is after groove puts in and turn clockwise 30 degree, and like this when cutter moves up, plunger bushing two omoplate ears are just stuck on inner groove surface, prevent plunger bushing to be taken out of by cutter, limit plunger bushing and move axially.
That is when using float type frock slightly to twist the operation of processing plunger bushing mesopore, down moved by machine tool chief axis, hinge top gem of a girdle-pendant cutter enters into inner hole of workpiece, due to the effect of the full part 7 (D7 diameter steel ball) of a circle in clamp body 2, positioning disk 3 can be rolled freely, indirectly make workpiece hole and main axle cutter centering, ensure coaxial, eliminate the coaxiality error of frock and main shaft.Workpiece is in process, workpiece can not be subject to the extra radial forces of frock, makes workpiece can with mesopore from as benchmark, uniform removal surplus slowly around blank hole, hole is had good geometric accuracy, and the phenomenon avoiding that processing do not get up.Namely improve the precision of hole machined in plunger bushing, reduce percent defective, improve production efficiency, reduce manufacturing cost.
Again after Curve guide impeller frock, the plunger bushing mesopore circularity of thick hinge processing obtains large increase, mesopore circularity is promoted to current about 1.5um by 3.5um ~ 4.5um before, the phenomenon that mesopore can not cut with scissors thoroughly is eliminated, allowance is reduced to current 0.03mm ~ 0.05mm by 0.06mm ~ 0.08mm before, machine because lathe has 8 main shafts to be divided into 8 times, therefore on average about 0.005mm is down to the reaning allowance of each axle by about 0.009mm, add and cut with scissors the top gem of a girdle-pendant cutter feed speed man-hour and be promoted to 250mm/min by 125mm/min before, working (machining) efficiency improves one times under the prerequisite not affecting stage property service life, greatly reduce production cost.
