Description
Technical field
The invention belongs to clamp arts, are related to a kind of multi-functional quick clamping mechanism.
Background technique
The equipment manufacture of China is developing rapidly, and new function product is constantly released, the precompressed compact form of general workpiece
Mostly artificial to compress, there are also use compression toolings to be compressed, but these compression toolings may be only available for single product, lead to
It is poor with property.With the development of science and technology the workpiece of various structures and shape is more and more, the special tooling of the single model of single product
Production Time does not catch up with the development of product, so most of still compressed using artificial, in the case where requiring Quick-clamped, people
The operation that work compresses, uses more troublesome, and the efficiency of clamping is lower, and safety coefficient is low.
Summary of the invention
The object of the invention is to solve the above-mentioned problems in the prior art, provide it is a kind of can be with to most of workpiece
General, clamping speed is fast, clamps high-efficient, the high multi-functional quick clamping mechanism of operating safety factor.
To achieve the above object, the technical solution of the invention is as follows: a kind of multi-functional quick clamping mechanism comprising base
Body, screw rod, cam spanner, sliding axle, active plate, follower plate, two hold-down heads and handle；
The center of the matrix is provided with variable diameter hole, and variable diameter hole lower end is the threaded hole that the screw thread on diameter and screw rod matches,
Upper end is the big unthreaded hole of diameter；Guide sleeve is fixed in unthreaded hole, the sliding axle that center is provided with screw rod via hole B is through in guide sleeve；
Sliding axle upper end is fixed on active plate lower end；It is provided on active plate and the screw rod via hole B of sliding axle is concentric, screw rod mistake with diameter
Hole A；After screw rod passes through screw rod via hole A, screw rod via hole B, it is threadedly secured in the threaded hole of matrix；Sliding axle lower end surface and matrix
Spring is cased on screw rod between the step in variable diameter hole；There is a wide in width in screw rod upper end, and wide in width is fixed between two walls there are two wall
There is pin shaft, cam spanner is rotatably mounted on pin shaft, pushes spanner, the cam of spanner is pressed on active plate, spanner is lifted,
The cam of spanner leaves active plate；Matrix upper surface is fixed with active plate rotary position-limit mechanism；
Described follower plate one end is rotatably installed in the one end of upper surface close to sliding axle of active plate by pin shaft, another
The end of end free end has been removably secured handle, is provided with handle shift slot in corresponding position on front side of active plate, active plate and
The free end of follower plate is respectively fixed with hold-down head；There is follower plate rotary position-limit mechanism on active plate.
It is further preferred that limit base can be fixed on same work far from matrix with matrix the invention also includes limit base
On platform；Limit base upper surface is provided with limiting slot；Pressure spring is installed on the handle of follower plate lower end, lower end is fixed with spacing head, limit
Potential head upper end diameter is approximately more than limiting slot diameter, lower end indent, can be in deep enough limiting slot, that is, spacing head is just clamped
On spacing edge-cut.Limit base is that handle provides a supporting role, to provide a supporting role for active plate and follower plate, is avoided
When mechanism does not work, follower plate and active plate are fallen due to weight, it is avoided to damage bindiny mechanism, the hair reduced the service life
It is raw.Spring can be such that spacing head is pressed in limiting slot.
It is further preferred that the hold-down head is the adjusting bolt that a bottom surface is spherical surface or plane, it is threadedly secured in
In the bolt mounting holes of active plate and follower plate, upper end is locked by locking nut.It adjusts bolt and it is adjusted fixed to master
Depth in movable plate or follower plate, to adjust the height for adjusting bolt presses workpiece.It is very easy to use.
It is further preferred that the active plate rotary position-limit mechanism that the matrix upper surface is fixed is a stop screw,
It is threadedly secured in matrix upper surface.Structure is simple, easy to implement.Limit the maximum displacement of active plate rotation.
It is further preferred that the follower plate rotary position-limit mechanism on the active plate is to open a limit hole on active plate
Or limiting groove, stop plunger compatible with limit hole or limiting groove is installed on follower plate.Follower plate is with respect to active plate
When rotation, stop plunger can slide on active plate, when it slides into limit hole or limiting groove on active plate, limited post
Plug is limited to limit hole or limiting groove under the action of the spring to be slided, to limit the dominant bit of follower plate rotation
It moves.
It is further preferred that described follower plate one end is rotatably installed in the upper surface of active plate close to sliding by pin shaft
The structure of one end of moving axis is: there is edge protuberance limit in the lower end of pin shaft, and there is a circle groove in upper end, and pin shaft is through actively from lower end
In the perforation pin shaft hole of plate and follower plate, circlip limit is caught in the groove of upper end；Pin shaft is closely assembled with active plate.Structure
Simply, practical, it is easy assembly.
It is further preferred that the sliding axle upper end is fixed on active plate lower end by screw.
When the present invention does not work, cam spanner lifts release, after master and slave movable plate rotates to together, by the spacing head of handle
It is parked on limiting slot.In use, being screwed into the depth in matrix screw thread hole according to workpiece height adjusting screw rod first, active plate exists
Reach maximum height under the action of spring, after adjusting screw rod, rotating handles, so that follower plate be driven to rotate, hand push or by from
Weight active plate rotation, when master and slave movable plate rotates to the position of workpiece needs, hold-down head face workpiece needs the position compressed,
Cam spanner, master and slave movable plate downlink under the compressing of cam are depressed, cam spanner compresses master and slave movable plate, finally adjusts hold-down head
Height, be tightly pressed against it on workpiece；After the completion of work, cam spanner is unclamped, handle is held and drives follower plate rotation, encounter
After active plate, handle is snapped into handle shift slot, also drives driving wheel rotation, when spacing head snaps into limit base, stop
Movement.As long as the height of adjusting screw rod of the invention, can adjust the height of master and slave movable plate, the height of pressure regulation hold-down head can also be micro-
The height of the tight position of pressure regulation, and can be used principal and subordinate's movable plate on two hold-down heads compress because master and slave movable plate can with relative rotation,
So angle between the two is adjustable, that is, the position on master and slave movable plate between hold-down head is adjustable, thus it is possible to use
Many a different shapes, various sizes of workpiece can also be when only single-point being needed to compress small workpiece or big workpiece
It is individually compressed with active plate.In short, the present invention can be general to most of workpiece, use scope is wide, to workpiece can quickly into
Row clamps, loosens, and clamping speed is fast, and clamping is high-efficient, and operating safety factor is high, and structure is simple, easy to use.
