Description
Technical field
It the utility model is related to plant equipment manufacture, specifically a kind of folder on numerical control end-face milling drill centres machine tool
Has floating claw mechanism.
Background technology
Numerical control end-face milling drill centres machine tool is the Digit Control Machine Tool based on working shaft-like both ends of the surface and two sides centre bore.
In large batch of bent axle, cam cutting, although clamping axial workpiece is simple, produce in enormous quantities and be the duplication of labour, still need to very
More set-up time, so as to increase single-piece manufacturing cost.Fixture is the mechanical device of connecting machine tool and workpiece, especially fixture card
Pawl mechanism, its function are positioning and clamping workpiece, workpiece is had correct position and good connection rigidity with respect to lathe, and then
The machining of workpiece can be completed high-quality and efficiently.Yet with meeting when workpiece bent axle, camshaft shaping in casting process
Die joint is left, and if using the clamp structure of traditional one side V-structure, one side parallel type structure, during clamp,
If die joint is in upright position, flat pattern claw easily clamps die joint, will result in position inaccurate.
The content of the invention
The purpose of this utility model is to provide a kind of numerical control end-face milling drill centres machine tool clamp floating click-on mechanism, fixture
Claw can effectively avoid clamping on die joint when clamping, and ensure clamping and positioning precision.
The utility model numerical control end-face milling drill centres machine tool clamp floating click-on mechanism, bilateral V-type claw, its feature exist
In：Floating claw and stationary jaw are all bilateral V-types, are separately mounted to the left and right sides of clamp body slide plate, and floating claw passes through
Bearing pin is fixed in the pawl seat of side, and stationary jaw is fixed on the master jaw of opposite side by feather key, the master jaw difference of both sides
It is fixed on the slide plate of both sides；Machine tool hydraulic system supplies to clamp body oil cylinder and clamps power, drives the slide plate and rack of side
Axle, opposite side drive the rack on slide plate by rack shaft, realize that the claw of offside two is synchronously opposite or heterodromous process is moved
Make, to realize that it is self-centering that synchronized jaw clamps workpiece, guarantee claw.
The clamp floating claw possesses following functions：When the 1st, using floating mechanism for card, floating claw is clamping irregular roundness
Blank when, the position of claw block can fluctuate around bearing pin, with the position of the circularity adjustment clamping point of blank, work after clamping
Part deformation is small, ensures part to be processed positioning accuracy request.2nd, because fixture is using the design of bilateral V-type claw, while fixation, one
Float on side, you can to avoid positioning from causing piece-holder unstable, while the position between workpiece positioning basal plane can be improved again
Precision is put, ensures the clamping and positioning required precision of part to be processed.
The design of this new floating claw makes workpiece obtain relative to lathe and knife compared with traditional clamping mode
The correct position of tool, and workpiece is reliably clamped.Benchmark is clamped with many superior functions and high-precision positioning.
Brief description of the drawings
Fig. 1 is numerical control end-face milling drill centres machine tool clamp floating click-on mechanism assembling sectional view；
Fig. 2 is Fig. 1 A-A sectional views；
Fig. 3 is the axonometric drawing of numerical control end-face milling drill centres machine tool clamp floating click-on mechanism.
Embodiment
The numerical control end-face milling drill centres machine tool clamp floating click-on mechanism of the design, using bilateral V-type claw, its feature
It is：Floating claw and stationary jaw are all bilateral V-types, are separately mounted to the left and right sides of clamp body slide plate, and floating claw leads to
Cross bearing pin to be fixed in the pawl seat of side, stationary jaw is fixed on the master jaw of opposite side by feather key, the master jaw point of both sides
It is not fixed on the slide plate of both sides.
Embodiment is as shown in figure 1, clamp body oil cylinder 1 is fixed in lathe one end, the tail skid 3 of its piston rod 2 and clamp body
Together, the lower vertical stationary rack axle 4 of tail skid 3, the combination vertical with the gear shaft 5 before lathe of the other end of rack shaft 4, tooth
Bar 6 is tangent on the top of gear shaft 5 and the circumference of gear shaft 5, therefore rack shaft 4 is parallel with the space of rack 6, before the top of rack 6 is fixed
Slide plate 7；Front clamp seat 8 is arranged on front slide 7, rear deck 9 is arranged on tail skid 3, and front claw 10 is solid respectively with rear claw 11
It is scheduled on front claw seat 8 and rear claw seat 9, front claw 10 or rear claw 11 are any when being floating claw, are fixed by bearing pin 12
Wherein in the pawl seat of side, front claw seat 8 or rear claw seat 9.
Clamp floating click-on mechanism drives fixture to body oil cylinder 1 by machine tool hydraulic system, and supply clamps power drive side
Slide plate and rack shaft, while drive piston rod 2, tail skid 3 and rack shaft 4 while move, pass through the gear shaft 5 of rack shaft 4
Band carry-over bar 6 moves, and makes the front slide 7 on its top and tail skid 3 while moves, so as to drive front clamp seat 8 and rear deck 9 simultaneously
Motion, opposite side drive the rack on slide plate by rack shaft, realize that the claw of offside two is synchronously opposite or heterodromous process
Action, ensure that claw is self-centering to realize that synchronized jaw clamps workpiece.
As shown in Fig. 2 bilateral V-type claw is any when being floating claw, for example, clamp floating claw is by the He of bearing pin 12
Pressing plate 13 is connected with rear claw seat 9, and 2mm gaps are left between the upper and lower surface of rear claw 11 and pressing plate 13 and master jaw 9, after
Claw 11 can fluctuate around bearing pin 12.Clamp in this way, can not only avoid workpiece die joint, ensure clamping point
Do not disturbed by die joint, it can also be ensured that the clamping point of workpiece is not disturbed by the irregular circularity shape of blank, ensures to clamp
Positioning precision.
The numerical control end-face milling drill centres machine tool clamp system uses left and right two sleeve clamps body, when ensureing workpieces processing
There are enough clamping forces.
Use state as shown in Figure 3：Numerical control end-face milling drill centres machine tool is in end face milling, because workpiece is all blank
Part, retaining part circularity is less uniform, and workpiece is clamped using the fixed V-type claw 10 of one end floating V-type claw 11 and one end, Gu
Fixed pattern V-type claw 10 plays certralizing ability, because 2mm gap is arranged at floating V-type claw 11 and gland 13 and the bottom of master jaw 9,
The position of adjustment clamping point so floating V-type claw 11 can fluctuate around bearing pin 12, ensure the card of floating type V-type claw 11
Rest shoe all touches workpiece, makes its clamping more firm.Lathe is when carrying out end face milling, drill centers, set turning, although work
Part bears that radial load, axial force are larger, but the fixture of the floating claw on the design numerical control end-face milling drill centres machine tool is set
Meter can ensure that clamping and positioning precision is more accurate.
