Technical field
The invention belongs to field of fixtures, be specifically related to a kind of self-adapting linkage clamping device towards the elongated class shape extrusion of on-plane surface and method.
Background technology
Long purlin class part is used for wing and the fuselage of aircraft, belongs to slender parts; Edge strip class design of part is complicated, and surface configuration non-planar features is obvious, for empennage and the wing of aircraft.At present, elongated class aerospace component is processed in the vertical direction often and is used vacuum suction, and the hydraulic caliper that horizontal direction uses milling machine to carry clamps.And due to upper and lower edge strip wall thickness changeable (between 2 ~ 3mm gradual change) during fine finishining, vacuum suction effect is undesirable, therefore just adopt traditional bolt clip plate mode come clamping work pieces (long truss members long ten meters to 20 meters not etc., production miller about organizes lathe clamp with more than 10, one group of clamp frock block installs two bolt clip plates, very long when the clamping time accounts for), this manual manipulation mode automaticity is low, large and the complex operation of labor strength, have a strong impact on working (machining) efficiency, and in clamping process, clamping force is uneven easily causes workpiece deformation, thus cause Workpiece Machining Accuracy low, even scrap.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, a kind of self-adapting linkage clamping device towards the elongated class shape extrusion of on-plane surface and method are provided, can evenly clamp, improve clamping efficiency.
In order to achieve the above object, a kind of self-adapting linkage clamping device towards the elongated class shape extrusion of on-plane surface comprises frock block, the side of frock block is provided with lathe clamp pedestal, lathe clamp pedestal is provided with two secondary groove limited blocks, two secondary groove limited block tops are provided with by the fixing some briquettings of caging bolt, briquetting offers slip through hole, and one end extends to above frock block, caging bolt is arranged with spring, driving cylinder is provided with between two secondary groove limited blocks, driving cylinder top connects the push rod with main groove, the rotating lever extending to and match with the briquetting other end above two secondary groove limited blocks is provided with in main groove, main groove is provided through main groove and rotating lever and the spacing bearing pin at rotating lever angle of inclination can be controlled.
Described rotating lever both sides are symmetrically arranged with secondary groove with main groove, and secondary groove is the rectangular block of " U " shape that Open Side Down, and rotating lever stretches into downward " U " shape portion of secondary slot opening.
Described secondary groove is provided with and is fixed in link bolt on rotating lever, secondary groove can do micro-swinging around link bolt.
The gap of 3 ~ 5mm is there is between described secondary groove inner wall end face and rotating lever end face.
Described rotating lever angle of inclination is ± 5 °.
Described driving cylinder by two groups totally four be bolted on lathe clamp pedestal.
Described briquetting is four, and four briquettings are symmetricly set on two secondary groove limited blocks.
Described spacing bearing pin is arranged on the centre of rotating lever.
Towards clamping means for the self-adapting linkage clamping device of the elongated class shape extrusion of on-plane surface, comprise the following steps:
Step one: be placed in by workpiece on frock block, starts driving cylinder, and driving cylinder drives push rod to move upward;
Step 2: the main groove on push rod top drives rotating lever to move upward;
Step 3: rotating lever moves upward and to contact with briquetting end, due to rotating lever both sides discontinuity, rotating lever is rotated by spacing bearing pin, makes rotating lever both sides uniform force;
Step 4: rotating lever moves upward briquetting end jack-up, makes briquetting front end press down, thus Work-sheet pressing.
Compared with prior art, the present invention passes through mounting limit bearing pin between the main groove of driving cylinder push rod end and rotating lever, spacing bearing pin makes rotating lever can rotate a little around center, vertical direction clamping force is made to be evenly distributed in rotating lever both sides according to surface of the work varied in thickness, thus reach vertical direction clamping force and be uniformly distributed and the object of Quick-clamped, operation is greatly simplified; The angle of inclination that can be changed rotating lever by rotary stopper bearing pin avoids the mechanical platen clamp originally needing to tight a bolt manually, not only labor strength can be greatly reduced, effective saving non-cutting time, improve working (machining) efficiency, and clamping is stable, the clamping force that each clamped position bears is also more even, not easily produce workpiece deformation, ensure that machining accuracy.
Further, the present invention is provided with secondary groove, can do micro-swinging around link bolt, thus further balances the clamping force on briquetting, adapts to on-plane surface workpiece better.
