Abstract
The utility model relates to a chambered thin-walled piece inner profile milling fixture for processing chambered thin-walled pieces. The fixture consists of a body (1), a supporting block (2), a rubber sheet (3), a guide pole (4), a bolt (5), a stretching screw (6), a locating pin (7) and a lifting bolt (8), wherein the body is rectangular with the upper end surface provided with a U-shaped groove, the side face of the long side of the body is provided with a rectangular through hole, and the upper part and the lower part of the side face of the short side of the body are respectively provided with mounting holes; a through hole for mounting the stretching screw is arranged in the center of a concave surface of the U-shaped groove on the upper end surface of the body; the supporting block is connected together with the body through the guide pole; the rubber sheet is stuck to two bevels of the supporting block; and the locating pin and the bolt are arranged on the upper end surfaces at both sides of the body. By adopting the locating pin, the supporting block and an adjusting bolt which are acted on a part together, the fixture solves the problems of difficult fixture location, bad rigidity, large processing deformation and hardly guaranteed precision, ensures the processing quality of the part and improves the production efficiency; in addition, the fixture is simple in structure and convenient for operation and has serial production and wide popularization and application values.
Description
Technical field: the utility model relates to a kind of interior shape milling fixture of arc thin-wall spare that is used for the processing of arc thin-wall spare.
Background technology: arc thin-wall spare processing, clamping location difficulty, poor rigidity, machining deformation are big, precision be cannot say for sure card, particularly produce in batches, under the situation that guarantees precision, realize high efficiency, especially a difficult problem.
Summary of the invention: the purpose of this utility model provide a kind of accuracy height, easy and simple to handle, can strengthen workpiece processing rigidity, can the arc thin-wall spare of quick-release workpiece in the shape milling fixture.Technical solution of the present utility model is, anchor clamps are made up of body, back-up block, rubber, guide pillar, screw, adjustment screw rod, alignment pin, lifting bolt, body is a rectangle, the upper surface has U type groove, the long side face of body has the rectangle through hole, and the short side has installing hole up and down; The concave surface center of the U type groove of body upper surface has the through hole that adjusting lever is installed, back-up block links together by guide pillar and body, rubber is bonded on two inclined-planes of back-up block, alignment pin and screw place on the upper surface of body both sides, and lifting bolt links to each other with body by top, body short side installing hole.
Advantage of the present utility model, this milling fixture, adopt alignment pin with back-up block, adjust the screw acting in conjunction in part, clamping location difficulty when having solved arc thin-wall spare and processing, poor rigidity, machining deformation are big, precision be cannot say for sure the problem demonstrate,proved, guaranteed the part processing quality, improved production efficiency, clamp structure is simple, and is easy and simple to handle, can be made into seriation, have application value more widely.
Description of drawings
Fig. 1 is a structural front view of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the vertical view of Fig. 1.
The specific embodiment
Anchor clamps are made up of body 1, back-up block 2, rubber 3, guide pillar 4, screw 5, adjustment screw rod 6, alignment pin 7, lifting bolt 8, body 1 is a rectangle, the upper surface has U type groove, and the long side face of body 1 has the rectangle through hole, and the short side has installing hole up and down; The concave surface center of the U type groove of body 1 upper surface has the through hole that adjusting lever 6 is installed, back-up block 2 links together by guide pillar 4 and body 1, rubber 3 is bonded on two inclined-planes of back-up block 2, alignment pin 7 and screw 5 place on the upper surface of body 1 both sides, and lifting bolt 8 links to each other with body 1 by top, body 1 short side installing hole.
The two-dimensional plane structural representation of interior shape milling fixture is seen Fig. 1, Fig. 2, Fig. 3, mainly by body 1, back-up block 2, rubber 3, guide pillar 4, screw 5, adjust screw rod 6, alignment pin 7, lifting bolt 8 is formed, workpiece is located on anchor clamps by the locating surface of alignment pin 7 and body 1, with screw 5 fixation workpieces, anchor clamps are fixed on the platen by body 1, rubber 3 is bonded on two inclined-planes of back-up block 2, regulating adjustment screw rod 6 can allow back-up block 2 move up and down along guide pillar 4, thereby workpiece is played the supplemental support effect, strengthen its processing rigidity, supplemental support is the adjustable elastic structure, adjustable structure solves the mistake orientation problem that supplemental support causes, it is little that elastic construction solves the contact area that the contact of conventional rigidity causes, the poor stability problem, supplemental support plays the effect of fast quick-detach workpiece simultaneously on the anchor clamps.
