Description
Technical field
The invention belongs to mechanical field, relate to a kind of can be fast, the jig of accurate adjustment workpiece Rotational eccentricity amount, relate in particular to a kind of chuck that can accurate adjustment.
Background technology
Three-jaw self-centering chuck, be used for the various metals lathe, utilization is distributed on moving radially of three movable jaws on chuck body, the workpiece of the shapes such as clamping that can self centering or stretching circle, triangle, hexagon outside face or inner surface, carry out various machinings, can satisfy the needs of general precision lathe.
Three-jaw self-centering chuck is comprised of a bevel gear wheel, three bevel pinions, three claws.Three bevel pinions and bevel gear wheel engagement, there is the flat thread structure at the back side of bevel gear wheel, and three claw deciles are arranged on flat thread.When moving bevel pinion with spanner, bevel gear wheel just rotates, the flat thread at its back side just make three claws simultaneously to the center near or deviate from because the pitch of flat thread equates, so the three-jaw move distance equates that self centering effect is arranged.
The clamp precision of three-jaw self-centering chuck is mainly determined by the accuracy of manufacture of chuck.In process, when the centre of gyration of workpiece is had relatively high expectations, usually to realize the adjustment of workpiece offset is wasted time and energy with knocking workpiece, correction accuracy is not high.
Summary of the invention
The objective of the invention is to propose a kind of adjust precision high, time saving and energy saving can accurate adjustment chuck.Technical solution of the present invention is, chuck comprises chuck transition tapered sleeve 1, dismounting nut 2, chuck transition piece 3, three-jaw self-centering chuck 7, it is characterized in that: chuck for installing adjustment plate 5 between three-jaw self-centering chuck 7 and chuck transition piece 3, a plane of chuck adjustment plate 5 is provided with boss, uniform three grooves 12 on the circumference of chuck adjustment plate 5 flange sections, each groove 12 is divided into the different two parts of diameter, the little partial-length of diameter is threaded 13 less than the large part of diameter on the groove of the part that diameter is little; A plane on chuck regulating part 10 is provided with boss, uniform three dimensions 14 on the boss excircle; Chuck adjusting lever 8 is divided into the conical surface 15 and screw thread 16 two parts, chuck adjusting lever 8 is placed in groove 12 on chuck adjustment plate 5 flange sections, plane 14 uniform on chuck adjusting lever 8 conical surface 15 parts and chuck regulating part 10 convex platform excircles overlaps, and on screw thread 16 parts of chuck adjusting lever 8 and chuck adjustment plate 5 flange sections, screw thread 13 parts of groove coordinate; The angle of inclination of the conical surface 15 of chuck adjusting lever 8 is less than the angle value of the arc tangent of the plane 14 contact surface coefficient of friction μ on the conical surface 15 of chuck adjusting lever 8 and chuck regulating part 10 boss excircles; Chuck adjustment plate 5 is connected with chuck regulating part 10 use screws; Chuck regulating part 10 is not connected by screw with end face and the chuck transition piece 3 of boss, and dish adjustment plate 5 is connected with three-jaw self-centering chuck 7 use screws with the end face of boss.
The conical surface 15 of described chuck adjusting lever 8 and the extruding force on the plane 14 on chuck regulating part 10 boss excircles are greater than chuck adjustment plate 5 and chuck regulating part 10 frictional force.
The advantage that the present invention has and beneficial effect:
The adjustment to workpiece Rotational eccentricity amount can be realized in the position that the chuck of accurate adjustment of the present invention only need be adjusted chuck adjusting lever 8, it is simple in structure, easy to use, use proof can realize the trace adjustment fast, accurately of workpiece Rotational eccentricity amount through reality, time saving and energy saving, and precision is higher.

The specific embodiment
The chuck of accurate adjustment mainly is comprised of chuck transition tapered sleeve 1, dismounting nut 2, chuck transition piece 3, chuck adjustment plate 5, three-jaw self-centering chuck 7, chuck adjusting lever 8, chuck regulating part 10 etc.Can be divided into 3 major parts by its function: chuck transition tapered sleeve 1, dismounting nut 2, chuck transition piece 3 are and the lathe syndeton; Chuck adjustment plate 5, three-jaw self-centering chuck 7, chuck adjusting lever 8, chuck regulating part 10 are the accurate adjustment structure; Three-jaw self-centering chuck 7 is clamp structure.
The accurate adjustment structure is between syndeton and clamp structure, and chuck regulating part 10 is not connected by screw with end face and the chuck transition piece 3 of boss, and chuck adjustment plate 5 is connected with three-jaw self-centering chuck 7 use screws with the end face of boss.
The assembly relation of accurate adjustment structure is: chuck for installing adjustment plate 5 between three-jaw self-centering chuck 7 and chuck transition piece 3, a plane of chuck adjustment plate 5 is provided with boss, uniform three grooves 12 on the circumference of chuck adjustment plate 5 flange sections, each groove 12 is divided into the different two parts of diameter, the little partial-length of diameter is threaded 13 less than the large part of diameter on the groove of the part that diameter is little; A plane on chuck regulating part 10 is provided with boss, uniform three dimensions 14 on the boss excircle; Chuck adjusting lever 8 is divided into the conical surface 15 and screw thread 16 two parts, chuck adjusting lever 8 is placed in groove 12 on chuck adjustment plate 5 flange sections, plane 14 uniform on chuck adjusting lever 8 conical surface 15 parts and chuck regulating part 10 convex platform excircles overlaps, and on screw thread 16 parts of chuck adjusting lever 8 and chuck adjustment plate 5 flange sections, screw thread 13 parts of groove 12 coordinate; The angle of inclination of the conical surface 15 of chuck adjusting lever 8 is less than the angle value of the arc tangent of the plane 14 contact surface coefficient of friction μ on the conical surface 15 of chuck adjusting lever 8 and chuck regulating part 10 boss excircles, self-locking with the plane 14 on the conical surface 15 of realizing chuck adjusting lever 8 and chuck regulating part 10 boss excircles, thereby guarantee after the external torque of rotating chuck adjusting lever 8 is cancelled, adjust the position and do not change; Chuck adjustment plate 5 is connected with chuck regulating part 10 use screws; Chuck regulating part 10 is not connected by screw with end face and the chuck transition piece 3 of boss, and dish adjustment plate 5 is connected with three-jaw self-centering chuck 7 use screws with the end face of boss.Its structure as shown in Figure 1.
Use spanner to rotate respectively 3 adjusting levers 8, adjusting lever 8 advances or retreats suitable distance, makes holding workpiece produce suitably small displacement on three directions, repeats above process, until holding workpiece Rotational eccentricity amount is adjusted in allowed band.
Rotating chuck adjusting lever 8, rotating chuck adjusting lever 8 is advanced at the groove 12 of chuck adjustment plate 5, produce the extruding force perpendicular to contact-making surface on the plane 14 on the conical surface 15 that coils adjusting lever 8 and chuck regulating part 10 boss excircles, under the effect of this extruding force, chuck adjustment plate 5 produces with chuck regulating part 10 and relatively moves, reach the effect to three-jaw self-centering chuck 7 fine position, thereby realize the adjustment to holding workpiece Rotational eccentricity amount.The pitch of the size of minimum amount trimmed and the screw thread 16 of the conical surface 15 angles of rotating chuck adjusting lever 8, rotating chuck adjusting lever 8, the minimum angles that chuck adjusting lever 8 can rotate are relevant; Maximum amount trimmed is relevant with the conical surface 13 angles, the length of rotating chuck adjusting lever 8.
