Description
Technical field
The utility model relates to a kind of fixture, particularly a kind of fixture of adjustable chucking power.
Background technology
Fixture most widely used in daily life is plain clamp, as: bench vice, bench vice etc.But common fixture does not generally have special force adjustment mechanism, the size of power is not easy to hold, and is easy to plastic deformation or damage occur for the workpiece that some materials are softer.And this jig Design has the frame for movement for force adjustment, to realize the controlled of clamping force.Most fixture can not adapt to various workpiece in addition, the workpiece of various shape.More such as there is no the workpiece of plane when being fixedly clamped with plain vice easily to corner angle and the surperficial damage caused in various degree of workpiece.
Summary of the invention
Technical problem to be solved in the utility model is: how to realize the controlled of holder power, thus does not cause the damage of folder.
The technical scheme that the utility model adopts is: a kind of fixture of adjustable chucking power, comprise base, be arranged on the quiet clamping head on base, dynamic clamping head, leading screw, quiet clamping head is connected with the end of thread of leading screw, dynamic clamping head comprises with leading screw without the dynamic clamping headstock of the end of thread by being rotationally connected, chuck fixture, one end is arranged on the other end on dynamic clamping headstock by adjustable nut and is arranged on the slide bar on chuck fixture, be arranged on the stiff end chuck on chuck fixture, be arranged on the snap ring that leading screw upper limit braking clamping head can not move axially along leading screw, spring housing is on slide bar.
As a kind of preferred embodiment: quiet clamping head comprise be connected with the end of thread lead screw pair of leading screw quiet clamping headstock, the turning cylinder be arranged on quiet clamping headstock, unilateral bearing on the rotating shaft, the runner be arranged on unilateral bearing, the multiple round end chucks be arranged on runner are installed.
As a kind of preferred embodiment: multiple round end chuck is connected by draw-in groove with runner, the groove on runner is regular hexagon counterbore, each round end chuck of multiple round end chuck has the regular hexagon prism projection coordinated with regular hexagon counterbore.
As a kind of preferred embodiment: the swing arm having convenient rotation without the end of thread of leading screw.
As a kind of preferred embodiment: snap ring is installed in the end, connection leading screw place of dynamic clamping headstock, and leading screw correspondence position has recessed groove, and snap ring is arranged in recessed groove.
As a kind of preferred embodiment: pass through the spacing connection of guide pillar on dynamic clamping head and on quiet clamping head, there is guide pillar seat guide pillar one end.
The beneficial effects of the utility model are: the utility model by regulating the tightness of adjustable nut and then control spring, thus can control the size of chucking power; Multiple round end chucks (the round end chucks of more than three or three) that quiet clamping head is installed by rotatable runner, can conveniently to the gripping of different folder; Multiple round end chuck is connected by draw-in groove with runner, and draw-in groove is regular hexagon, can when needed, the angle of adjustment swivel head, thus more convenient folder folder; Swing arm can make rotational lead screw laborsaving; Snap ring is a kind of specific implementation that the dynamic clamping head of realization can not move axially along lead screw shaft around lead screw shaft rotation.

Detailed description of the invention
As depicted in figs. 1 and 2, dynamic clamping head: two guide pillars 18 are loaded in the hole of dynamic clamping headstock 4, both interference fit are without relative motion, the other end of two guide pillars 18 is fixed together by guide pillar seat 14, be all interference fit (making two guide pillars 18 and guide pillar seat 14 be in interference fit state by tightening screw), the clamping headstock 4 without the end of thread 2 and carry out axial limiting with dynamic by snap ring 19 of leading screw, the two can not move axially, can only rotate, the end of thread 15 of leading screw and leading screw be two parts of Same Part leading screw without the end of thread 2, the end of thread 15 of leading screw with quiet clamping headstock for being threaded, rotating without the end of thread 2 of leading screw is driven by swing arm 3, make overall along clamping without the axial moving linearly of the end of thread 2 or unclamp workpiece.Stiff end chuck 9 fixture on dynamic clamping headstock 4 comparatively plain clamp also improves to some extent, conventional brace when clamping work pieces often power cannot control, once firmly the softer workpiece deformation of quality or surface of the work being made to occur comparatively macrolesion.Dynamic clamping head is comprised dynamic clamping headstock 4, chuck fixture 8, one end of being connected with leading screw and is arranged on by adjustable nut 5 and dynamic clamp the other end on headstock 4 and be arranged on the slide bar 7, the stiff end chuck 9 be arranged on chuck fixture 8 that pass spring 6 center on chuck fixture 8.By adjustable nut 5 can be suitable loosen or tighten up spring to adjust pretightning force.Chuck fixture 8 tightens together with slide bar 7, and chuck fixture 8 clamps headstock 4 form easy line slideway with dynamic, therefore chuck fixture 8 can slide on dynamic clamping headstock 4.Slide bar 7 clamps headstock 4 for axis hole matched in clearance be connected with dynamic, the two can play the guiding role by relative sliding, prevent again the damage caused because torque is excessive when clamping chuck fixture 8 and dynamic clamping headstock 4 simultaneously, spring 6 requires to have higher coefficient of elasticity, spring 6 is enclosed within clamping force when slide bar 7 making clamping work pieces a gradual process, the rotation without the end of thread 2 when clamping work pieces by controlling leading screw carrys out the size of the decrement of control spring 6 and then the power of control clamping work pieces, when the clamping force needed is very large, rotating threaded shaft make spring 6 be compressed to chuck fixture 8 without the end of thread 2 to contact with the dynamic cylindrical projection point right side clamping headstock 4, now the effect of its own resilient effect adjustment chucking power no longer reinstated by spring 6.
Quiet clamping head: quiet clamping headstock 16 passes through base connector 17 together with base screw fastening, turning cylinder 13 and quiet clamping headstock 16 are with together with key joint, the two is made relative motion not to occur, runner shaft 13 is connected by key with unilateral bearing 11 inner ring, and the outer ring of unilateral bearing 11 is connected by key with runner 10.Owing to there being the existence of unilateral bearing 11 to make runner 10 to be rotated counterclockwise, reverse self-locking.Runner 10 there are three positions of installing round end chuck 12, the round end chuck 12 adapted with surface of the work is installed on runner 10 for different workpiece, like this when changing round end chuck 12, only need rotating wheel 10, also desirable lower round end chuck 12 is changed.And chuck can also be made as required horizontal by certain angle (such as stationary wedge workpiece) by rotating wheel 10.Because round end chuck 12 and the installation form of runner 10 are that positive six prism grooved shapes coordinate so there are six setting angles, can need according to workpiece or personal habits installation round end chuck 12.
Workpiece for different profile uses different chucks, and as seen in figures 3-6, chuck can need to design various ways according to use.The chuck of Fig. 3 is applicable to the part (having the chuck of multiple common angle) that profile has corner angle class; The chuck of Fig. 4 is applicable to the part that profile is plane; The chuck of Fig. 5 is applicable to the part that profile is sphere; The chuck of Fig. 6 is applicable to the part that profile is Irregular Boundary Surface.
