Description

The general conical surface anchor clamps that mill

One, technical field

The utility model relates to a kind of plain-milling machine and mills conical surface anchor clamps, especially the anchor clamps of Jia Gong the vapour leaf part conical surface.

Two, background technology

Vapour leaf characteristics are as follows: 1. have only the blade profile part; 2. inner ring is an arc surface, and the outer ring is a taper seat; 3. the length overall tolerance is

Make a general survey of above characteristics, because its length overall tolerance is less, the processing of vapour leaf outer ring taper seat, it is the difficult point in the blade processing always, process unit is normal to adopt following two kinds of methods to process: (1) anchor clamps bottom surface pad cone angle cut away the circular arc method for processing with slotting cutter or line then, but the face that the method processes is the oblique circular cylinder face, non-true taper seat, length overall tends to overproof; (2) scan processing with Digit Control Machine Tool, though Digit Control Machine Tool precision height, lathe costs an arm and a leg, and general enterprise is too far behind to catch up, moreover, this method long processing time, programming needs the professional and technical personnel through training.

Develop a kind of suitable medium-sized and small enterprises, the common laborer can process the anchor clamps of true taper seat on plain-milling machine, is the needs of realizing that present vapour leaf is produced, can significantly reduce the input of enterprise.

Three, summary of the invention

The utility model has proposed a kind of suitable medium-sized and small enterprises at the problems referred to above, and the common laborer can process the anchor clamps of the conical surface exactly on plain-milling machine.

The utility model is achieved through the following technical solutions: general milling (plain-milling machine) milled conical surface anchor clamps, it is characterized in that constituting by rotary table, base plate, turntable base plate locating shaft, two retaining cross section molded lines locating pieces, clamping element and shockproof support, base plate is positioned on the rotary table by turntable base plate locating shaft, and two retaining cross section molded lines locating pieces, clamping element and shockproof support fixation are on base plate;

The blade profile at the place, back of the body arc location of the molded lines of two retaining cross section molded lines locating pieces of described anchor clamps and vapour leaf part to be processed is complementary, and two retaining cross section molded lines locating pieces are equipped with the location and use bound feet, and are connected on the anchor clamps base plate by hexagon socket head cap screw;

The clamping element of described anchor clamps is made of briquetting and briquetting back-up block; The shockproof support of described anchor clamps is made of shockproof back-up block, little axle and rolling bearing, and rolling bearing is connected with shockproof back-up block with hex nut by little axle, and shockproof back-up block is fixed on the anchor clamps base plate with hexagon socket head cap screw; Anchor clamps base plate and rotary table are located with turntable base plate locating shaft, and hexagon-headed bolt is fixed.

When using this anchor clamps clamping vapour leaf, only need vapour blade back arc blade profile is positioned on the two retaining cross section molded lines locating pieces, the inner ring arc surface is positioned on the end face straight pin, compresses briquetting then and gets final product.When processing the outer ring conical surface, the plain-milling machine universal milling head is deflected into required cone angle, rotates rotary table (the rotary table center is conical surface center, vapour leaf outer ring) then, just can process real taper seat easily.When vapour leaf specification changes, only need change corresponding two retaining cross section molded lines locating pieces, the position of adjusting inner ring end face setting circle pin gets final product.

The beneficial effects of the utility model are: the not only accurate positioning of these anchor clamps, clamping is quick, convenient, simple, and suitable vapour leaf scope is wide, the waste of having avoided processing to overpay clamp material, reduced production cost, simultaneously the management space of production scene anchor clamps has been saved greatly.
