It is merely convenient to understanding of narration, and is not used to limit the enforceable scope of the present invention, the change of its relativeness
Or adjust, changing under technology contents without essence, when being also considered as the enforceable category of the present invention.
As depicted in figs. 1 and 2, the present invention provides a kind of drift clamp for machining, including base 1, on base 1
Being provided with fixed platform 3, body 2, be provided with clamping device in body 2, fixed platform 3 upper surface is smooth, Gu
Fixed platform 3 upper surface is provided with the groove 31 placing drift to be processed, and the cross section of groove 31 is for cutting circle, groove
31 inner wall surface can fit tightly with the surface of drift to be processed, and the maximum perpendicular degree of depth of groove 31 is to be processed
The 3/5-2/3 of punch diameter.
As a kind of specific embodiment, the maximum perpendicular degree of depth is punch diameter to be processed the 3/4 of groove 31.
As a kind of specific embodiment, body 2 is provided with the sky accommodating clamping device in the face of the side of fixed platform 3
Between, accommodate clamping device spatially, lower surface be provided with prominent circular arc type keyway track.
As a kind of specific embodiment, clamping device includes claw, controls screw rod 6, power transmission shaft 7, claw position
In the space accommodating clamping device, described claw includes pawl 51 and a lower pawl 52, above props up pawl 51 He
The one end propping up down pawl 52 is hinged, the circular arc that described upper pawl 51 is prominent with the spatially surface accommodating clamping device
Type keyway rail contact, the circular arc type keyway rail that lower pawl 52 is prominent with the space lower surface accommodating clamping device
Road contacts, and controls screw rod 6 and penetrates from body 2 back side, one end of power transmission shaft 7 and described control screw rod 6 screw thread
Connect, the other end by link pins 8 and upper pawl 51, to prop up pawl 52 down hinged.Control screw rod 6 and use fixing
Screw 4 61 is fixed on body 2.
As a kind of specific embodiment, body 2 accommodates the left and right sides, space of clamping device and is provided with baffle plate 4, should
Baffle plate 4 is used for preventing claw from swinging.The upper and lower side of baffle plate 4 uses fixed screw 3 41 and alignment pin 42
It is fixed on body 2.
As a kind of specific embodiment, fixed platform 3 left and right sides fixed screw 2 32 is fixed on base 1
On, back out fixed screw 2 32, just can change fixed platform 3, to adapt to the drift to be processed of different-diameter.
As a kind of specific embodiment, the bottom of body 2 uses fixed screw 1 to be fixed on described base,
Body 2 is staggered relatively with fixed platform 3, is provided with spacing between body 2 and fixed platform 3.
When being processed, first the main part of column type drift to be processed is placed on the groove of fixed platform,
Make the column type drift that the head end of column type drift to be processed is concordant, to be processed with the head end side of fixed platform
Tail end insert upper pawl and an intermediate space for lower pawl.Tighten the control screw rod at body back, owing to controlling spiral shell
Bar is threadeded with power transmission shaft, so during tightening control screw rod, power transmission shaft can move to direction, body back, passes
Moving axis pulls claw, makes a pawl and lower pawl also move to direction, body back.Owing to upper pawl presss from both sides with accommodating
Hold the circular arc type keyway rail contact that the spatially surface of mechanism is prominent, lower pawl and the space accommodating clamping device
The circular arc type keyway rail contact that lower surface is prominent, so when upper pawl and lower pawl move to direction, body back
Time, the spacing above propped up between pawl and lower pawl also diminishes such that it is able to firmly clamp column type punching to be processed
The tail end of head, such whole column type drift to be processed is fixed on fixture, waits machining, cutting
Time, only need to machine away the cylinder drift part exceeding fixed platform horizontal plane, the punch in remaining groove
Divide this drift i.e..After drift machines, unscrew control screw rod, make transmission transport axially away from direction, body back
Dynamic, thus upper pawl and lower pawl also move to away from away from direction, body back, above prop up between pawl and lower pawl
Spacing become big, drift tail end is released, so that it may take out the drift machined.For different model sizes
Drift, fixed platform can be changed, different fixed platforms is corresponding to the drift of different model size.Change
Concrete grammar be to turn on the fixed screw two on fixed platform and base, take off the fixed platform on base, change
Model fixed platform needed for one-tenth.
A kind of drift, as it is shown in figure 5, use above drift clamp for machining to be fabricated by, this drift is cylindricality,
It is made up of arc surface 91 and plane 92, the 3/5-2/3 that the maximum perpendicular degree of depth is arc diameter of its cross-sectional area.
As a kind of specific embodiment, the maximum perpendicular degree of depth is arc diameter the 3/4 of the cross-sectional area of this drift.
As it has been described above, a kind of drift clamp for machining of present invention offer and the drift of manufacture thereof, design is a kind of special
The fixture of processing drift, this fixture can preferably be fixed round punch to be processed, can overcome round punch
Adding the difficult problem being difficult to clamping man-hour, highly versatile, fixed platform can be changed, different size of to be adapted to
Drift, simple to operate, accelerate the time of drift clamping, improve production efficiency, the drift application produced
Will not rotate in mould, it is thus possible to preferably fix mould, reduce the mould caused due to the rotation of drift and damage
Bad.So, the present invention effectively overcomes various shortcoming of the prior art and has high industrial utilization.
The principle of above-described embodiment only illustrative present invention and effect thereof, not for limiting the present invention.Appoint
Above-described embodiment all can be repaiied by what those skilled in the art under the spirit and the scope of the present invention
Decorations or change.Therefore, art has usually intellectual such as without departing from disclosed
All equivalences completed under spirit and technological thought are modified or change, and must be contained by the claim of the present invention
