In four above-mentioned axle deep hole drilling machines, described workpiece fixed claw comprises rotating shaft and is located at the gland in rotating shaft, and described rotating shaft rotates to drive gland to rotate by air cylinder driven.
In four above-mentioned axle deep hole drilling machines, described frock clamp is fixed on longitudinal slide unit, and longitudinal slide unit is arranged on longitudinal rail, and longitudinal slide unit can longitudinally slide under the driving of man-operated mechanism or motor drive mechanism or pneumatic mechanism or hydraulic mechanism.
In four above-mentioned axle deep hole drilling machines, screw mechanism is provided with between described longitudinal slide unit and longitudinal rail, the screw mandrel of screw mechanism is connected on longitudinal rail rotationally, the screw of screw mechanism to be screwed onto on screw mandrel and to be fixed on longitudinal slide unit, and screw mandrel drives it rotate and then drive longitudinal slide unit to slide on longitudinal rail by man-operated mechanism or motor drive mechanism or pneumatic mechanism or hydraulic mechanism.
In four above-mentioned axle deep hole drilling machines, described some straight jumping chisel is all driven by motor in synchrony and is: the tail end of some straight jumping chisels is all provided with driven synchronizing wheel, and driven synchronizing wheel all to be taken turns with the active synchronization be arranged on motor output shaft by Timing Belt and is connected.
In four above-mentioned axle deep hole drilling machines, the straight jumping chisel on described each horizontal slide unit has two, and the straight jumping chisel confront crosswise on two horizontal slide units is arranged.
In four above-mentioned axle deep hole drilling machines, described lathe bed side is provided with the channel of chip removal of the scrap that processing produces.
The present invention gives prominence to compared to existing technology and useful technique effect is:
The present invention have employed two motors be oppositely arranged to drive single or multiple drilling tool respectively, the rotating speed of each drilling tool is identical, reach transmission accurately steadily, work time fricton-tight, there is certain buffering, cushioning ability, the noise of Timing Belt synchronizing wheel is low, energy-saving effect is obvious, maintaining also facilitates, simplify greatly relative to existing multi spindle drilling machine equipment, originally processing automotive gearbox product needed more than 30 minute, only needs now the time of 5-7 minutes, has saved the production time, reduce required production cost, be applicable to produce in enormous quantities.

Detailed description of the invention
Below in conjunction with accompanying drawing, with specific embodiment, the invention will be further described, see Fig. 1-4:
Four axle deep hole drilling machines, comprise lathe bed 1, frock clamp is provided with in the middle part of described lathe bed, the both sides of frock clamp are respectively equipped with cross slide way 4, each cross slide way 4 is provided with can transversely guide rail 4 slide horizontal slide unit 5, two horizontal slide units are equipped with Workpiece boring mechanism, and described Workpiece boring mechanism is: each horizontal slide unit is provided with some straight jumping chisels 6, and some straight jumping chisels are all synchronously driven by the motor 7 on each horizontal slide unit.
Need the hole that disposable brill is arranged more in automotive gearbox in the present invention, often row need bore four holes, adopts common drilling machine to need four Set and Positioning, boring also needs to process for four times, if adopt four drill bits all to process in the same side, then easily cause workpiece unstable, make the hole got out have deviation.
Drive motors output torque drives some straight jumping chisels to rotate by Timing Belt, the synchronization that every root bores, and the brill of workpiece synchronously carries out, and the accuracy achieving porous controls.
The concrete structure of above-mentioned frock clamp is: base plate 11 is provided with several locating modules 12, locating module offers the locating hole 13 that several straight jumping chisels can pass, the base plate being positioned at locating module surrounding is provided with several workpiece fixed claws 14 driven by cylinder.
Above-mentioned frock clamp is fixed on longitudinal slide unit 3, and longitudinal slide unit 3 is arranged on longitudinal rail 2, and longitudinal slide unit 3 can longitudinally slide by guide rail 2 under the driving of man-operated mechanism or motor drive mechanism or pneumatic mechanism or hydraulic mechanism.
Screw mechanism is provided with between above-mentioned longitudinal slide unit 3 and longitudinal rail 2, the screw mandrel of screw mechanism is connected on longitudinal rail 2 rotationally, the screw of screw mechanism to be screwed onto on screw mandrel and to be fixed on longitudinal slide unit 3, and screw mandrel drives it rotate and then drive longitudinal slide unit 3 to slide on longitudinal rail 2 by man-operated mechanism or motor drive mechanism or pneumatic mechanism or hydraulic mechanism.
Above-mentioned some straight jumping chisel is all driven by motor in synchrony: the tail end of some straight jumping chisels is all provided with driven synchronizing wheel 9, and driven synchronizing wheel is all taken turns 10 by Timing Belt and the active synchronization be arranged on motor output shaft and is connected.
Above-mentioned active synchronization wheel length is more than or equal to multiple driven synchronizing wheel length sum, and driven synchronizing wheel to be taken turns with active synchronization by Timing Belt successively and is connected, and namely active synchronization is wound with Timing Belt on taking turns successively.
Straight jumping chisel on above-mentioned each horizontal slide unit has two, and the straight jumping chisel confront crosswise on two horizontal slide units is arranged.
Achieve workpiece clamped one time by said structure and can complete porous processing, relative in prior art, corresponding multiple processing brill is a drive motors, and structure is simple, and namely equipment cost is low, and having can according to the process requirements of reality, and increase and decrease processing is bored.
The actual process operation of the present invention is as follows: see workpiece in Fig. 3 18, be overlying on above-mentioned frock clamp, located by workpiece fixed claw, bore portion needed for workpiece matches with locating module and locates, horizontal slide unit transverse shifting drives straight jumping chisel through the locating hole of locating module, then workpiece is holed, many exhausting holes are processed as needed for workpiece in the present invention, the interlaced setting of straight jumping chisel of both direction, workpiece is not easily produced in process, and position, hole processing that the phenomenons such as skew back cause is not accurate.
The gland 16 that above-mentioned workpiece fixed claw comprises rotating shaft 15 and is located in rotating shaft, described rotating shaft rotates to drive gland to rotate by air cylinder driven.
Simplify operating process, the stability that fixedly ensure that workpiece in process in multiple orientation.
Described lathe bed side is provided with the channel of chip removal 17 of the scrap that processing produces.
Above-described embodiment is only preferred embodiment of the present invention, not limits the scope of the invention according to this, therefore: all equivalence changes done according to structure of the present invention, shape, principle, all should be covered by within protection scope of the present invention.
