Description
Technical field
Equipment, the especially process equipment that the utility model relates to the pitch cutting processing of nodular cast iron and alloy cast iron piston ring blank clamps the device of the Flexible Fixturing of blank piston ring to be processed, belongs to the numerical control machine tool technique field.
Background technology
Piston ring is one of part crucial in the internal combustion engine, and it plays effects such as supporting, sealing, guiding.What piston ring blank main flow both domestic and external still adopted is the biplate foundry engieering, behind the casting, mode by pitch cutting is divided into two again, what pitch cutting was at present mainly adopted is that speed lathe carries out monolithic processing, and clamping a slice is processed a slice, adds to clamp by three-jaw man-hour, because the blank of piston ring is an elliptical shape, the even working angles of unbalance stress during clamping not steady often causes the distortion and the internal injury of blank, brought very big hidden danger for later process and product quality.In addition, owing to be the processing of blank monolithic, the operation labour intensity of pitch cutting operation is big, and working (machining) efficiency is low, can not satisfy large batch of production demand.
The utility model content
The purpose of this utility model is at above-mentioned the deficiencies in the prior art, and a kind of semi-automatic piston ring blank combination pitch cutting lathe is provided.
The purpose of this utility model is to realize like this, semi-automatic piston ring blank combination pitch cutting lathe, comprise digital control system, main spindle box, chip removal mechanism, cooling body, depth-feed mechanism, Milling Process mechanism that installation is set on lathe bed and the lathe bed, it is characterized in that being provided with Flexible Fixturing mechanism, Flexible Fixturing mechanism is installed on the main shaft.
Described Flexible Fixturing mechanism is provided with pull bar, flange, axle sleeve, packing ring, rubber sleeve, tensioner watt, wedge, end face back-up ring, tapered sleeve, adjusting nut and rotary oil cylinder, wedge is sleeved on the awl bar section of pull bar middle part setting, tensioner watt is fixed on the wedge by lock-screw, rubber sleeve is sleeved on the tensioner watt, flange, axle sleeve, packing ring are installed on the pull bar of wedge one side, end face back-up ring, tapered sleeve, adjusting nut are installed on the pull bar of wedge opposite side, flange is installed and to be connected on the main shaft that main spindle box stretches out, and pull bar connects rotary oil cylinder.
The utility model science rational in infrastructure is manufactured easily, and is easy to use, improves piston ring blank pitch cutting working (machining) efficiency and quality.Processing when realizing the multi-disc piston ring blank that milling head by Milling Process mechanism drives the milling of multiple blade saw slitting milling cutter swivel feeding.Flexible Fixturing mechanism guarantees the steady of process to the Flexible Fixturing and the segmentation machining program of piston ring blank.Wherein Milling Process mechanism is installed on the depth-feed mechanism, and Milling Process partly drives cutter block and carries out Milling Process, and depth-feed mechanism is controlled by servomotor, cuts processing.Artificial with multi-disc piston ring blank clamping on the rubber sleeve of Flexible Fixturing mechanism, rotate with main shaft.Main spindle box is installed on the lathe bed, and it realizes main axis rotation by alternating current generator and worm-and-wheel gear.Flexible Fixturing mechanism is the core of equipment, is installed on the main shaft, is made up of critical components such as rotary oil cylinder, wedge shape tension structure, rubber sleeves.The interior circle of piston ring blank is enclosed within on the rubber sleeve, and tensioning mechanism drives the flexible support of the expansion realization of rubber sleeve cylindrical to piston ring inner circle, controls the dynamics of support by the pressure of regulating rotary oil cylinder.Digital control system has adopted the servo feed Control Shaft aspect digital servo control system, realize the multistage cutting speed by program, guarantees the steady of process.Semi-automatic piston ring blank combination pitch cutting lathe also is provided with automatic chip removal and cooling system, further improves product processing quality and efficient, the protection environment.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of Flexible Fixturing of the present utility model mechanism.
Among the figure: 1 lathe bed, 2 digital control systems, 3 main spindle boxes, 4 Flexible Fixturing mechanisms, 5 chip removal mechanisms, 6 Milling Process mechanisms, 7 depth-feed mechanisms, 8 pull bars, 9 flanges, 10 axle sleeves, 11 packing rings, 12 piston rings, 13 rubber sleeves, 14 lock-screws, 15 tensioners watt, 16 wedges, 17 end face back-up rings, 18 tapered sleeves, 19 adjusting nuts.
The specific embodiment
As shown in Figure 1 and Figure 2, semi-automatic piston ring blank combination pitch cutting lathe, constitute by installation digital control system 2, main spindle box 3, chip removal mechanism 5, cooling body, depth-feed mechanism 7, Milling Process mechanism 6, Flexible Fixturing mechanism etc. are set on the lathe bed 1, Flexible Fixturing mechanism is installed on the main shaft.Described Flexible Fixturing mechanism is made of pull bar 8, flange 9, axle sleeve 10, packing ring 11, rubber sleeve 13, tensioner watts 15, wedge 16, end face back-up ring 17, tapered sleeve 18, adjusting nut 19 and rotary oil cylinder etc., wedge 16 is sleeved on the awl bar section of pull bar 8 middle parts setting, tensioner watts 15 is fixed on the wedge by lock-screw 14, rubber sleeve is sleeved on the tensioner watt, and the multi-disc piston ring blank can be sleeved on rubber sleeve simultaneously and process.Flange 9, axle sleeve 10, packing ring 11 are installed on the pull bar (end that is connected being installed with main shaft) of wedge one side, end face back-up ring 17, tapered sleeve 18, adjusting nut 19 are installed on the pull bar of wedge opposite side, flange is installed and to be connected on the main shaft that main spindle box stretches out, and pull bar connects rotary oil cylinder.The expansion of rotary oil cylinder, pull bar, wedge, rubber sleeve, tensioner watt formation wedge shape tensioning mechanism drive rubber sleeve cylindrical realizes the flexible support to the piston ring inner circle that is nested with on it, controls the dynamics of support by the pressure of regulating rotary oil cylinder.
Pull bar is moved to the left under the effect of rotary oil cylinder, drives wedge and outwards expands, and the transmission by tensioner watt finally causes the expansion of rubber sleeve to come the stretching piston ring, under the effect of adjusting nut, tapered sleeve and end face back-up ring, comes the end face of hold-down ring simultaneously.Flange is contained on the main shaft, has guaranteed that entire mechanism rotates with main shaft.On the contrary, if pull bar moves right, then be pine folder piston ring.
