Abstract
The utility model relates to a boring and milling head. A box body is internally provided with a square ram. A square ram feed mechanism is installed between the box body and the square ram. A boring shaft is arranged in the square ram, and a boring shaft feed mechanism is arranged between the boring shaft and the square ram. The box body is internally provided with a driving gear shaft, an intermediate shaft, and a transmission spline shaft. The intermediate shaft is provided with a rack wheel and a pinion. The rack wheel is engaged with the driving gear shaft. A slippery pinion on the transmission spline shaft is coupled with a slippery rack wheel. The rear end of the square ram is coupled with a feed box. The slippery pinion is provided with a shifting fork, the box body is provided with an air cylinder, and the shifting fork is coupled with a piston rod of the air cylinder. A first feed lead screw in the boring shaft feed mechanism and a second feed lead screw in the square ram feed mechanism are respectively coupled with a motor. The air cylinder is manipulated to move the shifting fork to realize conversion of match between the slippery pinion and the slippery rack wheel as well as between the rack wheel and the pinion so as to change speed of the transmission spline shaft. The two feed lead screws are respectively coupled with the motors, and therefore not only are the two feed lead screws respectively controlled, but also the structure of the device is simplified.
Description
Technical field
The utility model relates to mechanical processing machine, specifically a kind of boring and milling head outer that is used for boring and milling machine.
Background technology
The basic structure of boring and milling head outer is the side's of being equipped with ram in the casing, ram feed mechanism in the side's of being equipped with between square ram and casing in existing a kind of boring and milling machine; In the boring axle side of the being loaded on ram; Milling spindle is loaded on the boring axle, and boring axle feed mechanism is housed between boring axle and the square ram, and driving gear shaft, jackshaft, drive splines axle are housed in the casing; Driving gear shaft connects with main motor; Be connected with transmission mechanism between drive splines axle and milling spindle, gear wheel, pinion are housed on the jackshaft, be connected with the slippage gear wheel on the slippage pinion that is equipped with on the drive splines axle.In the above-mentioned boring and milling head outer, the speed change of drive splines axle is to drive moving of slippage pinion through manual control mechanism to realize that the shortcoming that adopts manual control mechanism to exist is: the complexity of equipment increases, variable-speed operating control is convenient inadequately.In addition, in the existing this boring and milling head outer, the shared motor of square ram feed mechanism and boring axle feed mechanism, between these two feed mechanisms, needing increases transmission and clutch, and the deficiency of bringing thus is: the complexity of equipment increases, and the driving-chain of equipment increases.
The utility model content
The purpose of the utility model is to provide a kind of boring and milling head outer, in this boring and milling head outer the gear of drive splines axle simple in structure, control conveniently, and overall structure is simplified relatively.
For realizing above-mentioned purpose, the utility model adopts following scheme: a kind of boring and milling head outer that is used for boring and milling machine, the side's of being equipped with ram in the casing; The side's of being equipped with ram feed mechanism between side's ram and casing, in the boring axle side of the being loaded on ram, milling spindle is loaded on the boring axle; Boring axle feed mechanism is housed between boring axle and the square ram, driving gear shaft, jackshaft, drive splines axle are housed in the casing, driving gear shaft connects with main motor; Be connected with transmission mechanism between drive splines axle and milling spindle, gear wheel, pinion are housed on the jackshaft, gear wheel and driving gear shaft engagement; Be connected with the slippage gear wheel on the slippage pinion that is equipped with on the drive splines axle, the rear end of square ram is connected with feed box, on the slippage pinion, shift fork is installed; One cylinder is housed on the casing, and shift fork connects with the piston rod of cylinder; The rear end of second feed screw in first feed screw in the boring axle feed mechanism, the square ram feed mechanism is positioned at feed box; The rear end of feed box has respectively and first feed screw, installing hole that second feed screw is corresponding, and first feed screw, second feed screw connect with a motor through pairing installing hole respectively independently of one another.
Visible by such scheme, through manipulating cylinder shift fork is moved, can realize moving of slippage pinion, slippage gear wheel, accomplish they with gear wheel, pinion between the conversion that cooperates, and then the speed change of realization drive splines axle; Feed screw in feed screw in the boring axle feed mechanism, the square ram feed mechanism connects with a motor respectively; Can realize the control respectively of two feed screws; Can avoid again transmission and clutch are set between two feed mechanisms, make device structure obtain simplifying.
The utility model is rational in infrastructure, operation, control are convenient.
Description of drawings
The structural representation of Fig. 1 the utility model one embodiment;
The vertical view of Fig. 2 Fig. 1.
The specific embodiment
Further specify the utility model below in conjunction with embodiment and accompanying drawing.
Referring to Fig. 1, Fig. 2
The basic structure of the boring and milling head outer that the utility model provides is identical with prior art, the side's of being equipped with ram 12 in the casing 1, square ram 12 and 1 side of being equipped with of casing ram feed mechanism; In boring axle 15 side's of being loaded on rams 12; Milling spindle 16 is loaded on the boring axle 15, and boring axle feed mechanism is housed between boring axle 15 and the square ram 12, and driving gear shaft 2, jackshaft 6, drive splines axle 9 are housed in the casing 1; Driving gear shaft 2 connects with main motor 5; 16 of drive splines axle 9 and milling spindles are connected with transmission mechanism, and gear wheel 3, pinion 4 are housed on the jackshaft 6, gear wheel 3 and driving gear shaft 2 engagements; Be with slippage gear wheel 7 on the slippage pinion 8 that is equipped with on the drive splines axle 9, the rear end of square ram 12 is connected with feed box 14.The utility model with respect to the improvements of prior art is: shift fork 10 is installed on slippage pinion 8, a cylinder 11 is housed on the casing 1, shift fork 10 connects with the piston rod of cylinder 11; The rear end of second feed screw 17 in first feed screw 13 in the boring axle feed mechanism, the square ram feed mechanism is positioned at feed box 14; The rear end of feed box 14 has respectively and first feed screw 13, installing hole 14b, installing hole 14a that second feed screw 17 is corresponding, and first feed screw 13, second feed screw 17 connect (the motor omission that connects with first feed screw 13, second feed screw 17 among Fig. 1, Fig. 2) through pairing installing hole respectively independently of one another with a motor.
Referring to Fig. 1
