Description
technical field:
The utility model relates to a kind of feeder assembly of lathe, and the supporting adjustable oil cylinder thimble seat of lathe is squeezed in a kind of piston rod cold breakdown specifically.
background technique:
Cold rolling & extruding process is surface chill polishing processing method, and it is that tumbling axle by high hardness and smooth and workpiece surface carry out edging, makes workpiece surface material produce Plastic Flow, thus forms the technological method for processing of new surface roughness.Workpiece after cold rolling & extruding process, top layer metallographic structure refinement also produces residual compressive stress, improves the surface hardness of workpiece, bearing capacity, wear resistance, fatigue strength and corrosion resistance, and can obtain the superior work minute surface of surface property.
Current existing cold breakdown is squeezed lathe and is adopted branched tumbling axle and tapering turntable to combine, tumbling axle is driven to carry out roll extrusion to workpiece by rotating table, the similar tapered roller bearing of working method, its design concept is based on endoporus minute surface edging head, because its working method exists drawback, the advantage that cold breakdown is squeezed does not give full play to, and product does not reach cold breakdown and squeezes optimum efficiency.Such as: the easy spot corrosion of tumbling axle working surface, working life is low; Working stroke is by conicity regulation, and regulation range is little, requires strict, increase the technology difficulty of last process to the outer diameter tolerance of workpiece before rolling & extruding process; Processing high-hardness workpiece, when pressure increases, tumbling axle axial force is fixed stop, easy stuck tumbling axle; The workpiece of processing different-diameter must change turntable and correlated parts, and lathe is without versatility.
Current piston rod cold-extruded is pressed with two kinds of processing modes: one drives piston rod to rotate by lathe, and piston rod initiatively.Cold hobbing frock is placed on machine tool guideway and travels longitudinally, three roller extrusion piston bars in frock, roller and plunger rod contacts area larger, extruding force is also just large, lathe is low for working life, and due to piston rod active, workpiece loading and unloading must be shut down during operation, manufacturing efficiency is low, adopt drag motion, the center that rotating center and three rollers of piston rod form requires concentric, and very high to the requirement of guide rail linearity during longitudinal movement, piston rod easily produces bending deflection, affects the straightness accuracy of piston rod; Another kind is that piston rod is placed in cold hobbing frock, and frock is primarily of needle roller, and cages for needle and pressure adjusting dish form.Cages for needle stirs needle roller by belt drive, drives piston rod rotate and do straight line motion, due to needle roller working surface contact adjustment plate, makes needle roller surface easily produce spot corrosion, affect piston rod surface roughness.It is adjust by the tapering of needle roller that external force applies, and the outside dimension of piston rod must in the tolerance range of regulation, ability by and process; Like this, the process of last process is just required very strict, increase technology difficulty; Each constituent elements that lathe is squeezed in piston rod cold breakdown is extremely important.
summary of the invention:
The purpose of this utility model carries out orderly and automatically feed function to realize treating machining piston bar, provides a kind of piston rod cold breakdown to squeeze the supporting adjustable oil cylinder thimble seat of lathe.
The utility model adopts following technological scheme to realize its goal of the invention: the supporting adjustable oil cylinder thimble seat of lathe is squeezed in a kind of piston rod cold breakdown, and it forms cylinder ejector pin seat 1 by steel are refining; And be provided with cylinder ejector pin receiving groove 2, cylinder ejector pin seat mounting hole 3 thereon; Cylinder ejector pin receiving groove 2 is located at cylinder ejector pin seat 1 front left; Cylinder ejector pin seat mounting hole 3 is located at cylinder ejector pin seat 1 rear portion.
The utility model with applicable different-diameter piston rod function, is provided with cylinder ejector pin receiving groove 2 in order to realize being convenient to the adjustment of thimble; Cylinder ejector pin receiving groove 2 is located at cylinder ejector pin seat 1 front left.
Owing to have employed above technological scheme, the utility model achieves its goal of the invention preferably, the cold breakdown of this piston rod is squeezed lathe supporting adjustable oil cylinder thimble seat and has been drawn the advantage that lathe is squeezed in external corresponding cold breakdown, in conjunction with design itself feature, break the design concept that lathe is squeezed in existing cold breakdown completely, its exclusive working method, the advantage that cold breakdown is squeezed is not fully exerted, and quality of product reaches the optimum efficiency that cold breakdown is squeezed; Critical piece is provided with regulating tank to regulate according to the piston rod of different-diameter, the cylinder ejector pin receiving groove be wherein provided with, can be convenient to the adjustment of cylinder ejector pin with applicable different-diameter piston rod, ensured its versatility to piston rod.
accompanying drawing illustrates:
Accompanying drawing 1 is overall structure schematic diagram of the present utility model.
Description of reference numerals is shown in specification last page form.
embodiment:
Below in conjunction with accompanying drawing, model utility content is described further:
embodiment 1:
From summary of the invention, the supporting adjustable oil cylinder thimble seat of lathe is squeezed in a kind of piston rod cold breakdown, and it forms cylinder ejector pin seat 1 by steel are refining; And be provided with cylinder ejector pin receiving groove 2, cylinder ejector pin seat mounting hole 3 thereon; Cylinder ejector pin receiving groove 2 is located at cylinder ejector pin seat 1 front left; Cylinder ejector pin seat mounting hole 3 is located at cylinder ejector pin seat 1 rear portion.
The utility model with applicable different-diameter piston rod function, is provided with cylinder ejector pin receiving groove 2 in order to realize being convenient to the adjustment of thimble; Cylinder ejector pin receiving groove 2 is located at cylinder ejector pin seat 1 front left.
Cylinder ejector pin seat 1 described in the utility model refers to: the constituent elements of feeding mechanism; Which is provided with cylinder ejector pin receiving groove 2, cylinder ejector pin seat mounting hole 3; Its effect is convenient to install cylinder ejector pin; Its structure as shown in Figure 1.
Cylinder ejector pin receiving groove 2 described in the utility model refers to: be located at the dead slot on cylinder ejector pin seat 1; Cylinder ejector pin is placed in its effect; Its design attitude is as marked shown in 2 in accompanying drawing 1.
Cylinder ejector pin seat mounting hole 3 described in the utility model refers to: be located at the mounting hole on cylinder ejector pin seat 1; Its effect is convenient to install cylinder ejector pin seat 1; Its design attitude is as marked shown in 3 in accompanying drawing 1.
