Abstract
The utility model discloses a major axis class clamping device for parts machining, including the fixing base, on one side the fixing base up end is equipped with fixed centre gripping board, be equipped with movable grip block with fixed centre gripping board relative position, the activity grip block slides and sets up on the fixing base, and is fixed through bolted connection between fixed centre gripping board and the activity grip block, is equipped with the arc clamp plate in fixed centre gripping board and activity grip block top, and the tip has the portion of inserting under the arc clamp plate, inserts an outer wall and is equipped with rubber and compresses tightly the circle, and fix and be equipped with the backup pad on the centre gripping board, arc clamp plate rear end be connected with the depression bar, the depression bar passes the backup pad, with backup pad threaded connection. The utility model discloses the gram centre gripping adopts the bikini centre gripping fixed, adopts the mode of sphere at its top surface, great increase the area of contact of its anchor clamps and axle, increase the centre gripping effect, be equipped with at its sphere contact site simultaneously and compress tightly the circle, improved the reliability that compresses tightly.
Description
Technical field
The utility model relates to axle class processing technical field of auxiliary equipment, specifically belongs to a kind of longaxones parts processing clamping device.
Background technology
The effect of centrifugal force that superfine shaft bears self gravitation in turnery processing, cutting force, High Rotation Speed produce, as easy as rolling off a log appearance vibration and flexural deformation phenomenon, increase the error in geometrical form of axle, and the axial dimension of superfine shaft is comparatively large, diameter is less, heat diffusivity and poor rigidity, axially linear expansion can be being there is by heat in metal cutting effect, if cannot be eliminated at the elongation of axis, axle will be forced to bend, thus affect the precision of axle.It is existing that to shaft member processing, how employing scroll chuck fixes shaft member, this clamping device is not too large in cutting output, shaft member can ensure cutting precision shorter, but when cutting output is comparatively large, shaft member is longer, the effect of the centrifugal force that bearing produces by self gravitation, cutting force, High Rotation Speed, just proposes requirements at the higher level for grip strength.
Utility model content
For the problems referred to above, the purpose of this utility model there is provided a kind of longaxones parts processing clamping device, overcome the deficiencies in the prior art, clamping adopts bikini to grip, the mode of sphere is adopted at its end face, add the contact area of its fixture and shaft member greatly, increase clamping effect; Be provided with compacting ring in its sphere-contact portion simultaneously, improve the reliability of compression.
The technical solution adopted in the utility model is as follows:
A kind of longaxones parts processing clamping device, comprise holder, described holder upper surface is while be provided with fixed clamp plate, movable grip block is provided with fixed clamp plate relative position, movable grip block slides and is arranged on holder, be bolted fixing between fixed clamp plate and movable grip block, arc pressuring plate is provided with above fixed clamp plate and movable grip block, arc pressuring plate bottom has insertion section, described insertion section outer wall is provided with rubber compacting ring, fixed clamp plate upper end is provided with gripper shoe, described arc pressuring plate rear end is connected with depression bar, depression bar is through gripper shoe, be threaded with gripper shoe.
Described arc pressuring plate lower surface is spherical arc.
Described gripper shoe lower end is provided with support column, and support column lower end is fixed on base.
Described depression bar rear end is provided with rotating operating handle.
Compared with the prior art, the beneficial effects of the utility model are as follows:
The utility model clamping adopts bikini to grip, and adopts the mode of sphere, add the contact area of its fixture and shaft member greatly at its end face, increases clamping effect; Be provided with compacting ring in its sphere-contact portion simultaneously, improve the reliability of compression; A pair grip block employing is movable is convenient to secured adjusted, device compact overall structure, installs easy to operate.
