In the back of the oil feeder of the deep hole machine tool, there is a pipeline from the cooling pump, and the coolant is sent to the cutting area of the workpiece through the oil feeder. In the head of the oil feeder of deep hole machine tool, there is a conical disc 35041, which is used to support and tighten the workpiece. It is connected with the workpiece by a 30 degree conical surface, and tightens the workpiece by the force generated by the hydraulic cylinder installed on the top drag plate of the oil feeder. In the taper disc, there is a guide set 35040, which is used for boring head guidance. To replace the cutter, this set must be replaced. Specifically prompt users to face up to: prevent the selection of oil feeder head without cooling fluid, in order to prevent the seal ring from overheating! At the end of the oil feeder, there is a bearing inner sleeve 35015 and a guide sleeve 35016, which is used to support the boring rod. When replacing the boring rod, the response guide sleeve needs to be replaced. In the lower part of the top trawl of the oil feeder, there are two hydraulic cylinders at both ends of the trawl, which can clamp and fix the bed at four points at the same time. There are button boards and instruments in front of the oil dispenser, and almost all the control buttons of the footsteps at the root are searched. Therefore, the oil dispenser is also the core of machine tool domination. After starting the hydraulic pump, press the clamp button to realize the top tightening of the oil feeder, the active cycle of the clamping of the trawler to the bed and the top tightening of the workpiece, press the loosening button, then the cone disc and the top tightening trawler will be loosened, so that the oil feeder can move quickly. Within the specified processing scale, the user can choose the diameter and size of the drilling and boring rod by himself, and the parts related to the workpiece and the boring rod are cheap.
The function of the oil feeder is to properly guide the deep hole drill and supply the cooling fluid to the cutting area. Its type - deep hole processing manufacturers come to tell you:
(1) Non-rotating oil pressure head
The non-rotating oil feeder is composed of bracket, front seal ring, guide sleeve, telescopic shaft, handwheel, support nut, rear seal ring, etc. The support can tighten the movement and fastening of the machine tool guide. When drilling, the revolving handwheel is that the telescopic shaft is attached to the surface of the workpiece, and the front sealing ring is attached to the surface of the workpiece. Pressure oil enters the cutting zone through a telescopic shaft, through an annular gap formed between the drill body and the guide sleeve, and cools and lubricates the drill bit. The rear sealing ring is designed to prevent pressure oil from leaking out of the drill pipe. When the bit enters the workpiece, the guide sleeve guides the stable drilling. When the guide sleeve is worn out, it needs to be replaced in time. This oil feeder is mainly used for deep hole processing of tool rotation. Deep hole drill
(2) Rotary oil pressure head
Rotary oil feeder is mainly used for workpiece rotation or workpiece and cutter colleague rotation drilling method, is the most commonly used oil feeder. A rotating part is added to the head of the oil feeder to rotate the guide sleeve with the workpiece colleagues, which can improve the guiding accuracy of the cutter such as diamond.
(3) Micro oil pressure head
The space of the small diameter deep hole is limited. The micro oil feeder is composed of support, guide sleeve, moving shaft, locking nut, sealing ring and supporting nut. It does not need to use wrench to tighten and adjust the moving shaft to guide, seal and supply oil to the cutting area. When working, loosen the back locking nut, rotate the front locking nut, move the axle backward and take off the surface of the workpiece. The oil feeder is simple in structure and occupies little space.
