Abstract
The invention discloses a turning fixture for once clamping processing of a valve, wherein bottom outer side walls of a support block (6) and an angle iron module (1) are horizontal; a bottom central hole of the angle iron module is tightly matched with the central hole of the support block; a T-shaped bolt (5) is placed in the support block (6) through an opening slot, passes through two through holes on the bottom of the angle iron module (1) and then is fixed by a locking nut (2); a correcting block which is leveled is fixed on the support block (6) through a bolt (4); bottoms of two hanging bolts (10) are respectively arranged in the support block (6); top mounting pressing blocks (11) of the two hanging bolts (10) are fixed by hanging nuts (12); and a rotary spindle (8) is connected to the central hole of the support block (6) and the central hole of the angle iron module (1) through a gasket (7), thereby integrally forming the turning fixture. By using the turning fixture, the threads and openings at two ends of the valve can be once fixed and successfully processed by using a common lathe or a numeric control lathe, the cost is lowered, the processing efficiency is increased, and the problem of difficult processing of similar parts is thoroughly solved.
Description
Technical field
The present invention relates to a kind of jig, specifically and accurately say so disposable clamping machining screw formula flap type (mud valve) both ends screw thread and the turning clamp of opening shelves.
Technical background
At present, on the exploitation of oil gas field and wellhead assembly equipment, more and more use the flap type that is threaded, this type of flap type demand is increasing, and the channel center of the screw thread at two ends and valve body will keep higher axiality, two valve seat orifice sealing surfaces also need to guarantee its axiality and the depth of parallelism, processing request precision height.And existing processing method is with three-jaw clamping one end, proofreaies and correct the processing turning other end.The clamping that turns around is proofreaied and correct once more, the processing other end.And then repeat above-mentioned route processing valve seat orifice sealing surface and open shelves.Change multiple tracks technology according to above-mentioned process route needs, process is loaded down with trivial details, and difficulty of processing is bigger, and the process-cycle is long, and wasting manpower and material resources's resource causes bigger cost waste, and is difficult to satisfy the production of mass scale.
Summary of the invention
The objective of the invention is to: the turning clamp that a kind of disposable clamping processing of valve body is provided, make valve body two ends screw thread and drive shelves enough common lathes of energy or the disposable clamping of numerically controlled lathe and process successfully, reduce cost, improve working (machining) efficiency, thoroughly solve the like parts problem of difficult processing.
Technical solution of the present invention is: this turning clamp comprises the angle bar mould, back-up block, the rotation mandrel, correcting block, briquetting and balancing weight, the monoblock cast of angle bar mould forms, the bottom of angle bar mould is vertical with the back side, the front of angle bar mould is processed as dustpan mouth formula, dustpan mouth bottom is provided with two through hole and mesopore, angle bar mould top is established a balancing weight and is used for balance rotating, back-up block two check and correction faces are parallel and symmetrical, establish centre bore on the back-up block, a T type groove is established in back-up block inside, an open slot is established so that place T type bolt in back-up block T type groove top, the correcting block two sides polishes, establish two U type grooves on the correcting block, back-up block and angle bar mould bottom outside face level and angle bar mould bottom mesopore and back-up block centre bore close-fitting, T type bolt is in open slot is placed into back-up block T type groove, pass angle bar mould bottom two through hole again, and fix by locking nut, correcting block is fixed on the back-up block the mean longitude screw, the bottom of two hanging bolts is installed in the back-up block respectively, the top of two hanging bolts is installed briquetting and is fixed by hanging tight nut, the rotation mandrel is connected through packing ring on the mesopore of the centre bore of back-up block and angle bar mould, wholely constitutes turning clamp.
During installation, the angle bar mould is connected with the lathe headstock, guarantees the pivot unanimity; During processing work (valve body), select packing ring according to the different model valve body, packing ring endoporus close-fitting rotation mandrel, flange in the valve body is tipped upside down on the packing ring, and the packing ring cylindrical cooperates with flange endoporus in the workpiece, and the height of packing ring makes the center of valve body high consistent with the center of angle bar mould, make the center of workpiece (valve body) high consistent with the lathe pivot, proofread and correct, screw hanging bolt and compress briquetting, jack panel and correcting block screw are locked; After processing an end, come loose locking nut and correcting block screw, correcting block moves down along U type groove, 180 ° of whole rotational workpieces, back-up block, hanging bolt and briquettings, once more to flat first-class correcting block, bottom locking nut, the other end that promptly can processing work; When valve body was opened grade, turning processing was carried out in same whole rotation.
Useful effect of the present invention: 1, the present invention processes valve body, and disposable clamping does not need multiple conversions, processing is simple, reduce process time, reduce difficulty of processing, solve process complexity, the problems such as the technology road is more, processing cost is high, production limitation of this kind valve body completely; 2, adaptability is strong, and similar valve body processing is only needed to change packing ring, and assurance is high consistent with the center of lathe, promptly can process; 3, by being pressed on the whole Rotate 180 of valve body ° on the back-up block, processing is cut in the fixing laggard driving of correcting block, and is convenient to operation, guarantees the high-precision requirement of its size, form and position tolerance etc.
