Description
Technical field
The utility model relates to press technologies field, relates in particular to a kind of divided piston rod.
Background technology
Forcing press is that the mould that adapts to differing heights is installed needs, is generally equipped with height of packing compact governor motion, relies onThe length of regulating connecting rod realizes adjusting height of packing compact, and the most frequently used height of packing compact governor motion comprises and being threadedConnecting rod and screw rod, thus drive ball screw rotation to adjust height of packing compact by disc type electric machine by reducing gear, dress mouldThe variation of height shows by height of packing compact indicator. The connecting rod of forcing press adopts monolithic construction mostly at present,In the time of processing parts, need design specialized vehicle clamper, part heaviness is difficult to processing, and machining accuracy is low, after wearing and tearing, needsIntegral replacing, maintenance cost is high.
Utility model content
The technical assignment of technical problem to be solved in the utility model and proposition is that prior art is improved, and carriesFor a kind of divided piston rod, solve connecting rod traditional in current technology and adopt monolithic construction, be difficult to processing, processingPrecision is low, needs integral replacing after wearing and tearing, the problem that maintenance cost is high.
For solving above technical problem, the technical solution of the utility model is:
A kind of divided piston rod, comprises ball screw and gonnecting rod body, it is characterized in that, establish described gonnecting rod body bottomBe equipped with cavity, adjusting nut is set in cavity, the end of gonnecting rod body lower cavity is provided with bolt and pressing plate will be adjustedNut is fixed in cavity, and the inwall of adjusting nut is provided with screw thread, and ball screw and adjusting nut connect by screw threadConnect in the cavity of precession gonnecting rod body, the top of gonnecting rod body is fixed with connecting rod cap, forms bent between gonnecting rod body and connecting rod capAxle connecting hole. Divided piston rod described in the utility model adopts split-type structural, utilizes gonnecting rod body and adjusting nutBe combined to form original helicitic texture, ball screw is connected by helicitic texture with adjusting nut, ball screw is logicalOver-rotation is the overhang of capable of regulating ball screw, realizes the function that height of packing compact regulates. The utility model adoptsEach modular construction of Split type structure simple, can process more easily, reduce difficulty of processing, and adjustingAfter the helicitic texture wearing and tearing of whole nut, can only need to change adjusting nut, without whole connecting rod is changed, reduceMaintenance cost.
Further, on described bolt, be also provided with spring washer play locking used, guarantee pressing plate can be effectively byAdjusting nut is fixed in gonnecting rod body.
Further, on described pressing plate, be provided with straight pin, the pin-and-hole mating with straight pin be set on adjusting nut,Prevent the play of adjusting nut generation circumferencial direction, guarantee the degree of regulation of ball screw.
Further, on the wall of described gonnecting rod body lower cavity, be provided with force-feed oil cup for lubricated gonnecting rod bodyThe helicitic texture of internal adjustment nut and ball screw, guarantees to regulate smooth.
Further, the inwall of described bent axle connecting hole is provided with sliding bearing, ensures connective stability, improvesMachining accuracy.
Further, the contact-making surface of described adjusting nut and gonnecting rod body lower cavity is all light face, simple in structure,Conveniently processing, safeguards and changes conveniently, what adjusting nut was direct vertical puts into gonnecting rod body lower cavity, effectively protectsThe perpendicularity requirement of card connecting rod center and bent axle.
Compared with prior art, the utility model advantage is:
Divided piston rod described in the utility model adopts split-type structural, and each modular construction is simple, difficulty of processingLow, and easy to assembly between each parts, can effectively ensure the perpendicularity requirement of ball screw center and bent axle, carryThe machining accuracy of high pressure machine is high, does not need to design special vehicle clamper, and manufacturing cost reduces, after thread abrasion,Only need to change adjusting nut, use cost is low.
