Further, the axis of the first lag screw 1 and the axis of the second lag screw 3 are perpendicular to each other in the same plane.

Further, the number of the unthreaded holes on the V-shaped block 2 is 1.

Furthermore, the end part of the cam shift lever 6 is a sector, and a rotating shaft pin 5 is arranged at the position of the sector of the cam shift lever 6 deviating from the center.

Further, the V-shaped block 2 is a V-shaped iron block.

Compared with the prior art, the utility model following beneficial effect has:

the utility model discloses according to the diameter of waiting to process axle type spare, through the position of first lag screw and second lag screw adjustment V type piece to well fixed axle type spare, will wait the axle type spare of processing again and put in the processing structure, produce thrust to the cam driving lever through the lathe driving lever when adding man-hour, make the surface of cam driving lever extrusion axle, realize the quick tight effect of clamp of axle type spare. The utility model discloses a quick clamp of axle is realized to the effort of lathe driving lever to can change the position of V type piece through adjustment first screw and second screw, thereby adapt to the size of axle type spare, processing axle type spare that can be faster, line contact has been changed into by original point contact, the area of contact of axle type spare with processingequipment has been increased, the effort of acting on axle type spare on the surface has been reduced, the damage to axle type spare in the course of working has been reduced, manufacturing cost has been reduced promptly, and the production efficiency is also improved.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings: this embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation is given, but the scope of the present invention is not limited to the following embodiments.

The utility model provides a quick clamping device suitable for processing different shaft footpath machined parts, according to the diameter of waiting to process axle type spare, through the position of first lag screw 1 and the good V type piece 2 of second lag screw 3 adjustment to axle type spare 8 is fixed. And then the shaft 8 to be processed is placed in the processing structure. When in processing, the machine tool deflector rod 7 generates backward thrust to the cam deflector rod 6, so that the effect of quickly clamping the shaft parts is realized.

As shown in fig. 1, the present embodiment relates to a rapid clamping device suitable for processing workpieces with different shaft diameters, which includes: the device comprises a first square-head screw 1, a V-shaped block 2, a second square-head screw 3, a hoop seat 4, a rotating shaft pin 5, a cam deflector rod 6 and a machine tool deflector rod 7.

The utility model provides a quick clamping device suitable for processing different shaft diameter machined parts, puts V type piece 2 earlier in clamp seat 4, with first lag screw 1 and the precession of second lag screw 3V type piece 2 side guide rail groove in, through adjusting the precession back and forth position of first lag screw 1 and the precession back and forth adjustment V type piece 2 of second lag screw 3, again with the structure frock cover in the one end of treating processing axle class piece 8, at last with a shaft structure lift by crane on the belt machine tool. When the machine tool spindle rotates, a backward thrust is generated on the cam deflector rod 6 through the machine tool deflector rod 7, the cam deflector rod 6 rotates around the rotating shaft pin 5 to clamp the shaft part tightly, and the shaft is driven to rotate to realize the processing of the shaft part.
