Description

Double end multi-face forming production miller

The utility model relates to a kind of production miller, specifically a kind of double end multi-face forming production miller that is used to clamp series products processing.

Milling machine is the lathe that carries out Milling Process with milling cutter, and in the common mechanical manufacturing industry, milling machine occupies higher ratio in the Metal Cutting Machine Tool sum.The purposes of milling machine is very extensive, select for use dissimilar milling cutters can be on milling machine processing plane, groove, angled surface, profiled surface and cut-out, bore hole etc.Milling machine is carried out suitable adjustment or cooperates all right milling spiral surface or gear with corresponding annex.Existing a kind of milling machine that is exclusively used in the processing of pincers series products has parts such as two milling head boxs, lathe bed, workbench, power-equipment, and workbench is by hydraulic drive.The double end of this milling machine is lift adjustment separately, can only use a kind of cutter simultaneously, therefore clamping can only forming face of milling, need clamping again when processing another forming face once more, cause the secondary position error big, crudy instability, workbench have " creeping " phenomenon, and power consumption is big, work efficiency is low.

The purpose of this utility model is to provide an a kind of clamping multi-face forming or rough mills the one step completed double end production miller of finish-milling.

For achieving the above object, double end multi-face forming production miller of the present utility model comprises lathe bed, workbench, two milling head boxs, and each milling head box all is installed in separately the support guide groove by guide rail, support is installed in the vertical guide slot of lathe bed, and milling head box and support are regulated by screw mandrel.

Said workbench is provided with the cylinder type anchor clamps, and the dead jaw of these anchor clamps is fixed on the cylinder body, and the jaw of living is connected with piston; Workbench and anchor clamps are by the hydraulic system transmission.

The milling head main shaft tail end of said milling head box is provided with flywheel.

Said hydraulic system comprises motor, vane oil pump, manual governing valve, speed governing magnetic valve, anchor clamps magnetic valve, off-load magnetic valve, workbench magnetic valve.

Above-mentioned four magnetic valves and manual governing valve are installed on the integrated valve body of an intercommunication.

Because technique scheme has adopted two milling head boxs and milling head to support, can make milling head box vertical direction and vertically independent arbitrarily the adjusting by regulating screw mandrel, two milling heads adopt five forming faces that different cutters can clamping double end milling pincers series products, perhaps use same tool double end processing to make to rough mill finish-milling and once finish, be applicable to the specific (special) requirements of various technologies and various cutters.Eliminated the clamping error, improved crudy, working (machining) efficiency improves more than 2 times, and a people can operate 2 milling machines simultaneously, and integrated cost reduces more than 50%.

Anchor clamps jaw alive is connected with piston, and dead jaw and cylinder body connect into integral body, and Milling Force all acts on the clamp body, has reduced jaw load alive, owing to be hydraulic drive, can realize automatic degree of tightness anchor clamps, and clamping is fastening, accurate positioning.The flywheel that milling head main shaft tail end increases can increase rotary inertia, makes milling more steady, has eliminated the cutter stuck phenomenon.The vane oil pump flow that adopts is steady, pressure is high (6.3Mpa), has improved the stationarity of table feed, has avoided " creeping " phenomenon, vibrates for a short time, and noise is low.Set up the off-load magnetic valve, can make unnecessary oil in this valve flows into fuel tank, energy savings, life-saving.Hydraulic system element assembled arrangement adopts the integrated valve body of intercommunication to connect, and layout is concentrated, oil circuit is short, oil pipe is few.Complete machine power consumption capacity is 5.3KW only, and general universal milling machine saves 50%.

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is the schematic diagram of the utility model double end multi-face forming production miller;

Fig. 2 is the right view of Fig. 1;

Fig. 3 is the cutaway view of double end multi-face forming production miller anchor clamps;

Fig. 4 is the stereogram that double end multi-face forming production miller supports;

Fig. 5 is double end multi-face forming production miller circuit theory diagrams.

By Fig. 1, Fig. 2 as seen, double end multi-face forming production miller of the present utility model has lathe bed 1, workbench 2, lathe bed 1 is provided with two milling head boxs 3, the milling head main shaft tail end of each milling head box 3 all is provided with flywheel 4, the milling head main shaft bearing is selected the double row centripetal cylindrical roller bearing of band conical bore for use, and the main shaft diameter is bigger than general milling head.Workbench 2 is provided with anchor clamps 5.Milling head box 3 is installed in separately support 6 guide grooves by guide rail, supports 6 and is installed in the vertical guide slot 7 of lathe bed 1, and milling head box 3 is regulated by screw mandrel 8, supports 6 and is regulated by screw mandrel 9.The back side of lathe bed 1 is provided with fuel tank 10, and fuel tank and lathe bed connect into integral body, and oil back region and oil pump oil suction separate out, and is provided with the cooler heat radiation, and oily temperature is lower.Motor 11 is installed on the fuel tank 10, these motor 11 driven vane oil pumps 12, these pump 12 outputs are connected with the integrated valve body 13 of intercommunication by pipeline, valve body 13 is a cuboid, the top is equipped with manual governing valve 14, speed governing magnetic valve 15 is installed, anchor clamps magnetic valve 16, off-load magnetic valve 17 and workbench magnetic valve 18 on every side.Valve body 13 also can be other shape.Set up the off-load magnetic valve so that when certain magnetic valve is not worked, with the unnecessary oil that pumps in this valve flows into fuel tank.

Referring to Fig. 3, the anchor clamps 5 of double end multi-face forming production miller are the cylinder type structure, and dead jaw 19 is fixedly mounted on the cylinder body 20, and the jaw 21 of living is installed on the piston 22.Oil cylinder is connected with anchor clamps magnetic valve 16 on the integrated valve body 13 by pipeline near the connecting hole 23,24 of jaw 21 both sides of living.

Referring to Fig. 4, milling head box supports 6 and is L shaped, horizontal component is provided with guide groove 25, constitute swallow tail shaped slot by a contract piece 26 in the groove, contract piece 26 is connected with support 6 by screw rod again, milling head box 3 is installed in this guide groove 25 by guide rail, can vertically move along guide groove 25, and can milling head box 3 is fixed in the support 6 by the screw rod of regulating on the contract piece 26.Vertical component is a guide rail, is installed in the vertical guide slot 7 of lathe bed 1, can move as vertical direction.Also have a contract piece to constitute swallow tail shaped slot in the vertical guide slot 7, the screw rod of regulating this contract piece is fixed on the lathe bed 1 support 6.

Fig. 5 is the utility model circuit theory diagrams, and wherein travel switch 1XK, 2XK are installed on the lathe bed 1, and by workbench 2 controls, 3XK-1 and 3XK-2 are foot control travel switch.Each magnetic valve adopts the 24V dc source, and wherein, anchor clamps magnetic valve 1DT adopts energising to make clamp, and outage is unclamped anchor clamps.

Energising, relay 1J adhesive, workbench advances, and this moment, relay 1J normally-closed contact cut-off, and even mistake is stepped on switch 3XK-1, anchor clamps magnetic valve 1DT still cuts off the power supply, and anchor clamps clamp in the same old way.Relay 2J adhesive or travel switch 2XK close, anchor clamps magnetic valve 1DT energising, and anchor clamps unclamp automatically.Working table movement is divided soon, at a slow speed, and is quick during energising, during outage at a slow speed.Therefore in case break down, workpiece can not fly out and hurt sb.'s feelings, and workbench also is at a slow speed state and can damage equipment.
