Abstract
Disclosed is a damper piston rod snapping slot hobbing fixture. A bottom board is provided with a dovetail slot board through an adjusting base plate; the dovetail slot board is provided with a longitudinal adjusting dovetail which is compressed by a wedge-shaped pressing bar, and the longitudinal adjusting dovetail is provided with a fixture vertical board; a turning tool, a tool adjusting screw, a perforated dovetail strip and a support are mounted on the fixture vertical board; the turning tool and the fixture vertical board are compressed by a pressing block, and the perforated dovetail strip and the fixture vertical board are compressed by a pressing block; the perforated dovetail strip is provided with a support board, an adjustable U-shaped seat and a fine adjustment seat which are clamped on the perforated dovetail strip through a wedge-shaped pressing bar; an eccentric shaft is provided with a bearing and an isolation sleeve and mounted inside the hole of the adjustable U-shaped seat; a support is provided with an air cylinder through an air cylinder seat. The damper piston rod snapping slot hobbing fixture has the advantages of significantly improving the processing efficiency compared with existing turning modes, reducing the frequency of tool replacement and significantly improving the processing quality of workpieces.
Description
Technical field
The present invention relates to a kind of piston lever of reducer for automobile and roll the draw-in groove frock.
Background technology
Piston lever of reducer for automobile, in the draw-in groove process, adopts CNC Lathe Turning method processing draw-in groove mostly at present.The frequent blade of changing in operating process, production efficiency is low, and the product groove position fineness processed is coarse, and it is concentrated easily to produce stress, has reduced to a great extent the intensity of workpiece.
Summary of the invention
The object of the invention is to, solve above-mentioned existing existing problem, provide a kind of piston lever of reducer for automobile that efficiency is high to roll the draw-in groove frock.
The present invention is achieved through the following technical solutions: the adjustment backing plate is installed on base plate, adjust on backing plate the dovetail frid is installed, the vertical dovetail of adjusting is installed on the dovetail frid, vertical dovetail and the dovetail frid adjusted compresses with the wedge shape press strip, mounting tool riser on vertical tune dovetail, on the frock riser, lathe tool is installed, the toolsetting screw, coattail strip with holes, support, lathe tool and frock riser clamp with briquetting, coattail strip with holes and frock riser clamp with briquetting, on coattail strip with holes, supporting plate is installed, the adjustable U-shaped seat, fine tuning seat, the three uses the wedge shape press strip to clamp on coattail strip with holes, bearing is installed on eccentric shaft, spacer, and axle less than normal is arranged in adjustable U-shaped seat hole and uses nut check, cylinder block is installed on support, cylinder is installed on cylinder block, cylinder has been installed contact.
Advantage of the present invention is, while using original method for turning, every workpiece is about 5s man-hour, every cutter needs tool changing once while processing 1000, after turning, draw-in groove fineness guarantees at Ra1.6～Ra3.2, and after using this piston lever of reducer for automobile to roll draw-in groove frock processing mode, and every workpiece is about 1.6s man-hour, 10000 of every two cuttves processing only need tool changing once, roll draw-in groove after draw-in groove fineness guarantee below Ra0.8.After to sum up the draw-in groove frock is originally rolled in use, the more original turning mode of working (machining) efficiency increases significantly, and has reduced tool changing frequently, on the workpiece crudy, also increases significantly.
The accompanying drawing explanation
Fig. 1 is the installation diagram that piston lever of reducer of the present invention rolls the draw-in groove frock;
The A that Fig. 2 is Fig. 1 is to view.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail: as shown in the figure, be equipped with on base plate 1 and adjust backing plate 7, adjust on backing plate 7 dovetail frid 2 is installed, the vertical dovetail 3 of adjusting is installed on dovetail frid 2, vertical dovetail 3 and the dovetail frid 2 use wedge shape press strips 5 adjusted compress, mounting tool riser 6 on vertical tune dovetail 3, lathe tool 23 is installed on frock riser 6, toolsetting screw 15, coattail strip 8 with holes, support 16, lathe tool 23 clamps with frock riser 6 use briquettings 14, coattail strip 8 with holes clamps with frock riser 6 use briquettings 13, on coattail strip 8 with holes, supporting plate 20 is installed, adjustable U-shaped seat 9, fine tuning seat 21, the three uses wedge shape press strip 22 to clamp on coattail strip 8 with holes, bearing 12 and spacer 11 are installed on eccentric shaft 10, and axle 10 less than normal is arranged in adjustable U-shaped seat 9 holes and uses nut check, cylinder block 17 is installed on support 16, cylinder 25 is installed on cylinder block 17, contact 24 is installed on cylinder 25.
During use, frock of the present invention is fixed on screw-rolling machine by fixed head 4, slot rolling cutter 19 is arranged on the screw-rolling machine main shaft with hobboing cutter pressing plate 18.Use adjustable backing plate 7 regulating base boards 1 and the height of draw-in groove piston rod axis to be rolled to guarantee the rolled thread height correct at screw-rolling machine, the center line that is axis of workpiece height and slot rolling cutter 19 is contour, it is 130mm that the present invention uses the correct height of screw-rolling machine, then adjust lathe tool 23 to suitable height, using the end face of adjustable U-shaped seat is the positioning reference plane that rolls draw-in groove, adjust the slot rolling position with this, fine tuning seat 24 is used for trace and adjusts the slot rolling position dimension, and hobboing cutter pressing plate 18 is arranged on the screw-rolling machine thread rolling shaft with slot rolling cutter 19.During work, workpiece is placed on to the upper surface of frock riser 6, now cylinder 25 piston rods are for stretching out state, workpiece is pushed into to the locating surface of adjustable U-shaped seat 9, hobboing cutter 19 feedings, when hobboing cutter contacts with workpiece 26, hobboing cutter 19 drives workpiece 26 rotations, and the boss that hobboing cutter 26 squeezes out is flat by lathe tool 23 cars.After machining, hobboing cutter 23 is return, and cylinder 25 piston rods are retracted into the original position state.
