The specific embodiment
Accompanying drawing is the tube kind part cylindrical clamp for machining of the rice sieve support of processing 6NF series jet-air rice polisher.Rice sieve support is the multiaspect cylindrical part, and rice sieve support is the annulus of positive 6 tubes and a plurality of dowel is formed and length is long, poor rigidity by a plurality of inner chambers.Be difficult to clamp the end processing other end and cylindrical.Even if can process reluctantly, then the positional precision that is processed to form for twice is low.After using tube kind part cylindrical clamp for machining, can the whole cylindricals and the end face of rice sieve support be processed a clamping, just can guarantee the positional precision of all finished surfaces inner chamber.Tube kind part cylindrical clamp for machining adopts two common self-centering scroll chucks to be assembled on the axle, and the guiding mechanism and the rotatable supplemental support of distance between two chucks arranged.Detailed structure is as shown in Figure 1: a thin key (10) is contained in the keyway of mandrel (13) the left end diameter of axle and further compresses with screw (9) and corresponding spring washer, and this is to prevent from that a thin key (10) is long-term to use the insurance measure that comes off after becoming flexible under action of centrifugal force.The shape of a thin key (10) is, its an end cup head diameter is removed a part with external thickness direction, is contained in behind the keyway of axle in the face of cylinder of attenuation part before this keyseat.The chuck body of a chuck (6) be installed in its mesopore on this diameter of axle of mandrel (13) with retaining pad (4) and king-bolt (3) and accordingly spring washer chuck body (6) is pressed on the shaft shoulder of mandrel (13), the sulculus of the T-slot outside of the last chuck for installing pawl of chuck body (6) (8) cooperates with a thin key (10), the cup head of a thin key (10) one end attenuation is in mandrel (13) keyway that chuck body (6) mesopore is pushed down, facade above the cup head of attenuation is near the big groove bottom of T-slot the inside of chuck body (6), axial adjustment cover (12) is contained on the double-screw bolt of mandrel (13), and its small end end face is pressed in the T-slot end of chuck body (6).When needs regulate two chucks apart from the time unclamp king-bolt (3), chuck body (6) is moved to the left under the promotion of axial adjustment cover (12) needs the position, uses king-bolt (3) that chuck body (6) is compressed again.The length that a thin key (10) can transmit moment of torsion from the big groove bottom of T-slot the inside to the right.The structure of key head attenuation, transmitting moment of torsion at a thin key (10) has under the situation of sufficient length, and adjustable distance increases.If do not adopt a thin key, semi-circular portions length that can not the reliable delivery moment of torsion has reduced adjustable distance.
The chuck body of another chuck (6) is contained in its mesopore on the diameter of axle of mandrel (13) right-hand member and is close to the shaft shoulder, the sulculus of the outside of the T-slot on the chuck body (6) is alignd with keyway on mandrel (13) the right-hand member diameter of axle.T shape key (15) enters the diameter of axle keyway that is contained in mandrel (13) right-hand member from the T-slot of chuck body (6) outside and compresses with screw (9) and corresponding spring washer, the narrow key that reaches T shape key (15) partly with chuck body (6) on T-slot outside the purpose that cooperates of sulculus.The narrow key of T shape key (15) partly leans against the top axial location of chuck body (6) on mandrel (13) that realized of T-slot the inside vat of chuck body (6) with the joint face of wide key partial-length direction.See accompanying drawing 3.The wide key part bottom of T shape key (15) is narrow key part.
Thrust ball bearing (16) is contained in the mesopore of mandrel (13) right-hand member chuck body (6), the bearing plate that cooperates with chuck body (6) leans against the right-hand member end face of mandrel (13), another bearing plate of thrust ball bearing (16) is contained on the left end diameter of axle of rotating shaft (19), two deep groove ball bearings (18) also are contained on the left end diameter of axle of rotating shaft (19) and with two pads (17) thrust ball bearing (16) and two deep groove ball bearings (18) are separated, the outer ring of two deep groove ball bearings (18) is contained in chuck body (6) mesopore, the deep groove ball bearing (18) on the right leans against on the shaft shoulder of rotating shaft (19), and the right-hand member of rotating shaft (19) has and the coaxial centre bore of the bearing diameter of axle is installed;
What tube kind part cylindrical clamp for machining adopted all is common self-centering scroll chuck, is made up of chuck lid (5), chuck body (6), chuck parcel (7), chuck jaw (8), chuck pusher dog (11).Three chuck jaws (8) that are installed on the same chuck body (6) are gone up apart from the mesopore radial axis outer face farthest of chuck body (6) identical to the distance of the middle axially bored line of chuck body (6),, have near chuck parcel (7) end in the outer face apart from the arc-shaped surface of outer face certain distance.Its effect is to leave certain space for the processing parts end face on the one hand, be on the other hand when the manufacturing of clamp mechanism, can prop up a technology annulus, the outer face of three chuck jaws (8) of processing chuck can easily reach the distance identical requirement of the outer face of three chuck jaws (8) to the middle axially bored line of chuck body (6).In order to guarantee the precision after tube kind part cylindrical clamp for machining is assembled, the endoporus that requires chuck body (6) to be connected with ring flange (1) is coaxial to the mesopore of chuck body (6), and the end face that chuck body (6) is connected with ring flange (1) is vertical to the mesopore of chuck body (6).Can when processing chuck body (6) mesopore again, reach this requirement.Because the mesopore of two chuck bodies (6) all is a mating holes, the chuck body on the right (6) mesopore will be installed bearing, and the intermediate pore size of general two chuck bodies (6) is identical, all by bearings mounted cooperation requirement processing.
Because the inner chamber of the rice sieve support of 6NF series jet-air rice polisher is six letters, so it is the plane that the chuck jaw (8) that the tube kind part cylindrical clamp for machining of husked rice screen frame (unit) is used is gone up apart from the mesopore radial axis outer face farthest of chuck body (6), this plane is vertical with the central plane of going up T-slot outside sulculus by the chuck body (6) of axially bored line in the chuck body (6), and is parallel with axially bored line in the chuck body (6).Mandrel (13) is gone up the thin key (10) of installation and is equated with the width of keyway that T shape key (15) is installed, and the central plane of two keyways is in same plane, and the common axis of the diameter of axle of two chuck bodies of installation (6) is gone up on this plane by mandrel (13).
It is coaxial that mandrel (13) is gone up the diameter of axle that two chuck bodies (6) are installed, and mandrel (13) is gone up near the end face of thrust bearing (16) vertical with the common axis of the diameter of axle that two chuck bodies (6) are installed.
The use of tube kind part cylindrical clamp for machining is installed in big endoporus and the end face thereof of anchor clamps by left end chuck body (6) on the ring flange (1) of machine tool chief axis with stove bolt (2).Rice sieve support is installed on the clamp mechanism decides scroll chuck automatically with two ends and clamp,, just can process the two-stage cylindrical and the end face thereof of rice sieve support in the lump with the top centre bore that withstands rotating shaft (19).The precision height of beating of all machined surfaces and rice sieve support inner chamber axis like this.
