Abstract
The invention relates to a machining clamp. The machining clamp comprises a clamp body and a machined part. A supporting block is arranged on the clamp body, the head portion of the machined part is placed in a groove of the supporting block, the abdomen portion of the machined part is clamped to a clamping base through hook-shaped pressing plates, and two supporting legs of the machined part are clamped through a first clamping mechanism. The first clamping mechanism comprises a wedge block adjusting assembly, the wedge block adjusting assembly comprises a screw, a wedge block and a screw plug, the screw is fixed to the wedge block, and the wedge block moves relative to the screw plug. By means of the machining clamp, the machined part can be firmly clamped, and thus subsequent machining is greatly guaranteed.
Description
Technical field
The present invention relates to auto parts and components processing technique field, especially relate to a kind of machining fixture.
Background technology
In modern mechanical manufacturing, machined is scope of application processing mode the most widely, as long as the part that required precision is higher or surface roughness requirements is thinner, all needs to carry out machined on lathe.At present, the frock clamp that machining uses on lathe mostly is manual operations, structure is comparatively simple, some are resembled to the parts in irregular shape such as fork-shaped workpiece, clamping is a difficult problem, and the clamping force of each clamping hand-operated clamping is difficult to be consistent, and causes product quality to be difficult to ensure card, particularly need the operation of milling flat, scientific and reasonable clamping is very important.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of rational in infrastructure, operate time saving and energy saving, clamp firmly machining fixture, to overcome the deficiencies in the prior art.
The technical solution adopted for the present invention to solve the technical problems is: machining fixture, comprise clamp body, machined piece, clamp body arranges back-up block, the head of machined piece is placed in the groove of back-up block, the belly of machined piece is clamped on clamping seats by hook pressure plate, two legs of machined piece are clamped by the first clamp system, described first clamp system comprises voussoir adjusting part, described voussoir adjusting part comprises screw, voussoir, plug screw, described screw is fixed on voussoir, and described voussoir moves relative to plug screw.
First back-moving spring is set between voussoir and plug screw.
Described first clamp system also comprises pair of sliding pressing plate, moving press plate, fender plate, described sliding clamp is between two legs being arranged on machined piece, described voussoir adjusting part is arranged between two sliding clamps also by two sliding clamp tensioners inside the leg of machined piece, can arrange described moving press plate, fender plate at an outside of foot for machined piece respectively.
Described hook pressure plate is arranged on positioning seat, in positioning seat, arrange lining, arranges cross-tie in lining, the built-in roller in one end of cross-tie, tapered bar passes perpendicularly through the hole of pull bar, and the wedge surface of tapered bar is resisted against on roller, the other end of cross-tie connects outside link, and outside link connects hook pressure plate.
The end of thread of described outside link stretches out in hook pressure plate, the external part attaching nut of outside link.
Second back-moving spring is set in one end of cross-tie, at the inner of outside link socket the 3rd back-moving spring.
Beneficial effect of the present invention is as follows:
The belly of machined piece is clamped on clamping seats by hook pressure plate by the present invention, and the head of machined piece is placed in the groove of back-up block, and two legs of machined piece are clamped by the first clamp system.Therefore, machined piece can clamp, for follow-up machined provides strong guarantee by this fixture securely.
