Specific implementation mode
To make the technical means, the creative features, the aims and the efficiencies achieved by the present invention be easy to understand, with reference to
Specific implementation mode, the present invention is further explained.
Referring to Fig.1-6, present embodiment uses following technical scheme：A kind of Mutifuction universal document clip of resilient clamping force
Tool, including straight-line movement portion and stationary part, the straight-line movement portion include movable part fixture supporting rack 4, swing arm
3, fixing end collet 9, sliding bar fixing piece 14, sliding bar 18 and leading screw, the stationary part include stationary part fixture branch
Support 16, pedestal 1, runner 10, unilateral bearing 11, round end collet 12, runner shaft 13, base connector 17, movable part folder
Has the main body that supporting rack 4 is straight-line movement portion, one end of two sliding bars 18 is fixed on the hole of movable part fixture supporting rack 4
In, the other end of two sliding bars 18 is fixed together by sliding bar fixing piece 14, is passed through on movable part fixture supporting rack 4
Fixed mechanism is equipped with fixing end collet 9；The leading screw is made of leading screw non-threaded end 2, threads of lead screw end 15, leading screw non-threaded
End 2 passes through one end of movable part fixture supporting rack 4 to be equipped with swing arm 3, threads of lead screw end 15 and stationary part fixture supporting rack
16 are threadedly coupled, and stationary part fixture supporting rack 16 is the main body of stationary part, and stationary part fixture supporting rack 16 passes through pedestal
Connector 17 is screwed together with pedestal 1, and 16 upper end of stationary part fixture supporting rack is connect by key with runner shaft 13,
Both make that relative motion does not occur, the inner ring of runner shaft 13 and unilateral bearing 11 by key connection, the outer ring of unilateral bearing 11 with
Runner 10 is by key connection, due to there is the presence of unilateral bearing 11 to make runner 10 that can only rotate counterclockwise, reverse self-locking, and runner
Round end collet 12 is installed on 10.
It is worth noting that, the sliding bar 18 is interference fit, nothing between the two with movable part fixture supporting rack 4
Relative motion；It is connected by screw between sliding bar 18 and sliding bar fixing piece 14, is all interference fit, is made by tightening screw
Sliding bar 18 is in interference fit state with sliding bar fixing piece 14.
Clamp spring 19 is installed between the leading screw non-threaded end 2 and movable part fixture supporting rack 4, by clamp spring 19 come
Axial limiting makes the two that cannot move axially, can only rotate.
In addition, the fixed mechanism of the fixing end collet 9 is made of nut 5, spring 6, slide bar 7, collet fixing piece 8,
One end of slide bar 7 is mounted on the upper end of movable part fixture supporting rack 4 by nut 5, and spring 6, slide bar 7 are socketed on slide bar 7
The other end fixed by collet fixing piece 8, fixing end collet 9 is installed on collet fixing piece 8.
Present embodiment fixture is symmetrical, integrally divides two large divisions：A part is straight-line movement portion, another
Part is stationary part.Wherein in straight-line movement portion, drives leading screw non-threaded end 2 to rotate by swing arm 3, make linear motion portion
It is point whole along threads of lead screw end 15 it is axial it is for linear motion come clamp or release workpiece, the folder on movable part fixture supporting rack 4
Head fixing device dynamics when clamping workpiece is controllable, can suitably be loosened by rotating nuts 5 or tighten spring 6 to adjust this
The pretightning force of fixture；Collet fixing piece 8 is fastened as a whole with slide bar 7, due to collet fixing piece 8 and movable part fixture supporting rack
4 constitute easy the linear guide, therefore collet fixing piece 8 can slide on movable part fixture supporting rack 4, slide bar 7 and shifting
Dynamic part fixture supporting rack 4 connects for axis hole clearance fit, and the two person opposite can slide and play the guiding role, while prevent from pressing from both sides again
The damage to collet fixing piece 8 and movable part fixture supporting rack 4 is caused when tight since torque is excessive.Spring 6 require compared with
High coefficient of elasticity, spring 6 is sleeved on slide bar 7 clamping force when making clamping workpiece, and there are one gradual processes, when clamping workpiece
The size that the power of workpiece is clamped by controlling the rotation at leading screw non-threaded end 2 come control control the decrement of spring 6 by, when need to
When the clamping force wanted is very big, rotating threaded shaft non-threaded end 2 makes spring 6 be compressed to collet fixing piece 8 and the support of movable part fixture
4 cylindrical projection point right side of frame contacts, and spring 6 no longer plays the role of own resilient adjustment chucking power, the structure at this time
Dynamics is controllable, is not in a workpiece deformation that may firmly make quality softer or the case where workpiece surface damage.
In stationary part, the position of round end collet 12 is installed on runner 10 there are three settings, different workpiece can be directed to
The round end collet 12 that installation is adapted with workpiece surface on runner 10 only needs to revolve in this way when replacing round end collet 12
Rotating wheel 10 also can use lower round end collet 12 and be replaced, and can also be made as required by rotating wheel 10
Collet is horizontal by certain angle, such as stationary wedge workpiece；The round end collet 12 and 10 hexagonal prisms groove profile of runner
The mounting structure of cooperation, so collet there are six setting angle, can need according to workpiece or personal habits install collet.
Present embodiment round end collet 12 can need to be designed as diversified forms according to using, for different shapes
Workpiece use different collets, such as the first form in Fig. 3 collet A be suitable for shape have corner angle class part (have
The collet of a variety of common angles)；The collet B of second of form in Fig. 4 is suitable for the part that shape is plane；In Fig. 5
The collet C of three kinds of forms is suitable for the part that shape is spherical surface；It is not that the collet D of the 4th kind of form in Fig. 6, which is suitable for shape,
The part of ruled surface；Above-mentioned various forms of collets are convenient for that the special-shaped workpiece of a variety of curved-surface shapes is effectively clamped.
Present embodiment has the adjustable function of chucking power, is mainly used for irregular shape and unlike material
Workpiece grips, and is suitble to a variety of different curved-surface shape piece-holders, avoids injury to personnel in work progress, and reduce
Damage of the fixture to workpiece entirety and surface, realization is preferably clamped and protects to special-shaped workpiece, for the different of curved-surface structure
Gripping for shape workpiece provides reliable guarantee.The fixture is easy to carry, easy to operate, and clamping has both been suitable for have curved
The special-shaped workpiece of state, and resilient clamping force can be provided in clamping process, have a vast market application prospect.
The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
Equivalent thereof.
