Cross pull bar and connect hydraulic jack, so can regulate the center of product by the gap between loose flange and clamping dish and look for
Just, follow-up clamping is facilitated；Described mounting flange is arranged on the side of clamping dish, and described mounting flange is set in outside pull bar
Enclosing, described locating support is vertically set on the side of mounting flange.
Illustrate further, in technique scheme, described locating support is additionally provided with fixing bolt.Such design
It is that product is bolted on locating support by fixing by operator for convenience, facilitates follow-up lathe process.
Illustrating further, in technique scheme, the opposite side of described mounting flange is additionally provided with balance weight.Such
Design is the degree of balance in order to increase overall lathe process, it is to avoid the bias produced during processing bias and special-shaped product
The motion loss to power of motor, effectively protection motor balance movement, reduces the abrasion to machine, improves lathe service efficiency.
Illustrating further, in technique scheme, described bolt is spherical bolt.Such design be for
Clamped product is automatically positioned the centering at center.
Illustrate further, in technique scheme, described bolt regulation center angular range be 0 °～
15°.Such design is to realize the trim process to clamped product, because product is green state when, and appearance
Surface roughness is high, during clamping, facilitates operator's automatic capturing to its center.
Illustrate further, in technique scheme, described clamping dish and loose flange interstice coverage along the circumferential direction
Being 0～10mm, the interstice coverage between described clamping dish and loose flange plane is 0～2mm.Such design is to realize
Trim process to clamped product, because product is green state when, outer surface roughness is high, in the process of clamping
In, facilitate operator's automatic capturing to its center.
Illustrating further, in technique scheme, the interstice coverage between described mounting flange and clamping dish plane is 0
～1mm.
After using above-mentioned bias and special-shaped product Special clamp device, simple in construction, by spherical bolt and work
Dynamic flange can utilize the locating support on mounting flange to be fixed product, it is ensured that product adds with the fast automatic centre of location
Working medium amount, reduces Product processing cost, facilitates the handling of operator, improves production efficiency.
Accompanying drawing explanation
The present invention is further detailed explanation with detailed description of the invention below in conjunction with the accompanying drawings:
Fig. 1 is the structural representation of the present invention；
In figure: 1 is chuck, 2 is claw, and 3 is bolt, and 4 is mounting flange, and 5 is loose flange, and 6 is clamping dish, 7
For pull bar, 8 is hydraulic jack, and 9 is locating support, and 10 is fixing bolt, and 11 is balance weight.
Detailed description of the invention
As shown in Figure 1 be a kind of eccentric and special-shaped product Special clamp device, including chuck 1, claw 2, location spiral shell
Bolt 3, mounting flange 4, loose flange 5, clamping dish 6, pull bar 7, hydraulic jack 8 and locating support 9；The outfan of chuck 1 is movable
Connecting and have claw 2, claw 2 is provided with along claw 2 shrinkage direction bolt 3, the input of chuck 1 is provided with clamping dish
6, the internal clearance of clamping dish 6 is provided with loose flange 5, and one end of loose flange 5 passes the center of clamping dish 6 and passes through pull bar
