Description
Technical field
The present invention relates to a kind of gear rack machining apparatus, relate in particular to a kind of rack saw, bore, mill unit.
Background technology
Present large-scale tooth bar is because length and width are all larger, so that its profile of tooth is difficult to one-shot forming, needing could be so that its tooth Profile Machining moulding through multistep or multiple devices, so not only manufacturing procedure is more, the processing personnel labor intensity is large, and processing cost is high, and owing to processing at multiple devices, so that the profile of tooth that processes may be not in full conformity with standard, so that defect rate is higher.
Summary of the invention
Defective and deficiency that the present invention exists in order to solve above-mentioned prior art, provide a kind of can be so that the profile of tooth time processing moulding of large-scale tooth bar, reduce manufacturing procedure, reduce labor strength and processing cost, reduce simultaneously defect rate rack saw, bore, mill unit.
Technical scheme of the present invention: a kind of rack saw, bore, mill unit, comprise base, electrical system, hydraulic system and cooling system, be provided with successively some vertical band sawing machines, some drilling heads and some milling heads on the described base, some vertical band sawing machines, some drilling heads and some milling heads are symmetricly set on the base respectively in twos, described base middle part is provided with the slide of carrying workpiece, and described slide is provided with that tooth pitch moves and the locking positioning device.
Preferably, described tooth pitch moves and the locking positioning device comprises tooth pitch mobile device and locking positioning device, and the tooth pitch Shift cylinder stroke of described tooth pitch mobile device is identical with the distance of adjacent two between cog.
The tooth pitch Shift cylinder stroke of tooth pitch mobile device is identical with the distance of adjacent two between cog, guarantees that piston rod drives the every movement of slide unit consistent size once.
Preferably, the oil cylinder of described locking positioning device is two oil cylinders of lifting one's head, and the oil cylinder head is equipped with the locating piece consistent with castellated appearance.
When the every movement of tooth pitch Shift cylinder once, the oil cylinder of locking positioning device just utilizes the profile of tooth location after the last time sawing, makes slide block carry workpiece and both can accurately locate on slide, can lock again, guarantee that workpiece is not shifted in the process of sawing, affect tooth pitch and profile accuracy.So circulation is until that whole rack saw cuts is complete.
Preferably, described slide is provided with the moving slider for fixation workpiece.
Preferably, described tooth pitch moves and the locking positioning device is arranged on both sides, moving slider top, matches with the location of workpiece in its position.
Preferably, the quantity of described vertical band sawing machine, drilling head and milling head is four, and all is symmetricly set in twos the both sides of base.
The present invention is specifically designed to the processing of large-scale tooth bar, adopt the mode of vertical band sawing machine, drilling head, milling head combination that tooth bar is processed, left and right tooth bar slab is through welding with the radian plate, integrated stress is installed on the slide unit after eliminating, and simultaneously a plurality of teeth of tooth bar is processed by vertical saw, drilling head, milling head, the required profile of tooth of one-shot forming, reduce manufacturing procedure, reduced labor strength and processing cost, reduced simultaneously defect rate.
