The automatic clamp comprises a mould frame, V-shaped positioning blocks, clamp spherical heads, hydraulic oil cylinder connectors and hydraulic oil cylinders, wherein screw holes for mounting of the hydraulic oil cylinders are formed in the two ends of a bottom plate of the mould frame; countersunk head screw holes for mounting of the V-shaped positioning blocks are formed in the two ends of an upper plate of the mould frame; a body of each V-shaped positioning block is provided with a thread hole connected with the upper plate of the mould frame and the angle alpha of the inclined plane is 10 degrees; the two hydraulic oil cylinders are respectively fixedly arranged at the two ends of the bottom plate of the mould frame by screws; the hydraulic oil cylinder connectors are fixedly connected with piston rods of the hydraulic oil cylinders by threads; the hydraulic oil cylinder connectors are sleeved with the clamp spherical heads; the two V-shaped positioning blocks are respectively fixedly arranged at the two ends of the upper plate of the mould frame by screws; a positioning key is arranged at the bottom of the bottom plate of the mould frame and is fixedly arranged at the bottom of the bottom plate of the mould frame by a screw and a pin.
Description
Technical field
The utility model relates to a kind of frock clamp, particularly a kind of frock clamp that is used for processing tubing tensile sample.
Background technology
At present, processing tubing tensile sample, adopts universal knee-and-column milling machine to process mostly, and drawing pipe sample is as shown in accompanying drawing 7,8.Add man-hour, generally adopt two bench vices to clamp tubing tensile sample 6, then at drawing pipe sample 6 both sides Milling Process breach 6-1.There is following problem in above-mentioned job operation: the one, and when clamping drawing pipe sample, because being adopts two bench vices to do clamp device, drawing pipe sample location is inaccurate, and after clamping, drawing pipe sample is easy to occur rugged phenomenon; The 2nd, the breach on drawing pipe sample both sides is added to man-hour, the bad control of length; The 3rd, after breach of Milling Process drawing pipe sample, the breach on reprocessing opposite, two breach are difficult to accomplish symmetry.Therefore, after drawing pipe sample processes, be difficult to meet the requirements.A undesirable drawing pipe sample, the experiment of working it out, will there is error in experimental data.
Summary of the invention
The purpose of this utility model is overcome the above-mentioned deficiency of prior art and a kind of frock clamp that is used for processing tubing tensile sample is provided.
The technical solution of the utility model is: a kind of automatic fixture of processing tubing tensile sample, comprises framed, V-type locating piece, fixture bulb, hydraulic jack joint and hydraulic jack.The two ends of framed base plate are respectively equipped with the screw hole for hydraulic jack is installed, and the two ends of framed upper plate are respectively equipped with the sunk screw hole for V-type locating piece is installed.The body of V-type locating piece is provided with the threaded hole being connected with framed upper plate, and the angle a on its inclined-plane is 10 °.Two hydraulic jacks are separately fixed at the two ends of framed base plate by screw, hydraulic jack joint is threaded connection on the piston rod that is fixed on hydraulic jack, and fixture ball-head cover is contained on hydraulic jack joint.Two V-type locating pieces are separately fixed at the two ends of framed upper plate by screw.Bottom at framed base plate is provided with positioning key, and positioning key is fixed on the bottom of framed base plate by screw and pin.
In the time that universal knee-and-column milling machine is processed tubing tensile sample, automatic fixture is fixedly mounted on universal knee-and-column milling machine, again the concave surface of drawing pipe sample is placed on to fixture bulb, primer fluid compressing cylinder, after steel pipe tensile sample being withstood on the V-type face of V-type locating piece, close hydraulic jack, then adjust the position of steel pipe tensile sample, restarting hydraulic jack holds out against steel pipe tensile sample, Milling Process is carried out in drawing pipe sample both sides, and in drawing pipe sample both sides, Milling Process goes out breach.
The utility model compared with prior art has following features:
1, the fixture Milling Process drawing pipe sample that adopts the utility model to provide, guarantee that drawing pipe sample machining precision reaches requirement of experiment, during due to jig Design, take into full account drawing pipe sample processing concentricity, drawing pipe specimen clamping is in fixture, drawing pipe sample center is concentric with fixture, this concentricity is by fixture V-block and the top self-centering of oil cylinder sphere, then proofread and correct milling cutter and the fixture depth of parallelism, CNC milling machine programmed, autofeed withdrawing is carried out in milling, guarantees the breach absolute symmetry of drawing pipe sample both sides.
2, this fixture once can be processed one to four tensile sample simultaneously, and work efficiency is high, good product quality, and labor strength is low.
Below in conjunction with the drawings and specific embodiments, detailed construction of the present utility model is further described.
