Description
Technical field:
The present invention relates to a kind of numerical control machine for processing with the equipment of ram, relate to a kind of equipment of giving the ram deep hole processing specifically.
Background technology:
Digit Control Machine Tool is 80-280mm with axial diameter is arranged in the ram body, length is the deep hole of 2300-4500mm, present processing method is with the machine tooling that drilling tool is housed, shortcoming with existing drilling tool deep hole processing is: because the drill bit afterbody of existing drilling tool is identical with drill pipe diameter, after about every processing 20mm, drilling tool will be taken out and carry out a chip removal, and very bother, process velocity is slow.In addition, because the length of deep hole is big, the drill bit rotation of drilling tool has vibration, so the ram concentricity that processes is poor, product quality is bad.
Summary of the invention:
Technical problem to be solved by this invention provide a kind of when processing ram deep hole chip removal smooth and easy, chip removal is fast, process velocity is fast, the deep hole working machine of product good concentricity.
Above-mentioned purpose is achieved in that it comprises lathe bed, fixedly there is the head of a bed at the rear portion of lathe bed, chuck axis is contained on the head of a bed by bearing, chuck is contained in the front end of chuck axis, on the lathe bed of the head of a bed below motor reducer is arranged fixedly, the belt pulley on the motor reducer power output shaft is connected with belt with the belt pulley of chuck axis rear end;
Slideway is fixedly arranged on the lathe bed upper surface, and centre frame is positioned at the place ahead of the head of a bed, and centre frame is contained on the slideway, and centre frame can forward and backward movement on slideway, adjusts distance between itself and the chuck according to Workpiece length;
It is characterized in that: also comprise tailstock, tailstock is contained in the slideway in centre frame the place ahead, screw is arranged at the tailstock bottom, the lathe bed front end fixedly has motor reducer, leading screw is contained in the screw of tailstock bottom, leading screw is connected with the motor reducer power output shaft by shaft coupling, main shaft is contained in the tailstock by bearing, front-end of spindle is equipped with screw, manually leading screw is contained in the tailstock of front-end of spindle, and manually the rear end of leading screw is threaded with the screw of front-end of spindle, and manually the front end of leading screw stretches out from main shaft, extension is equipped with handwheel, and rear-end of spindle is stretched out from tailstock; Also comprise drilling tool, drilling tool comprises hollow drill, one end of hollow drill is connected with drill bit, the other end is connected with tail cone, and tail cone is connected with the rear end of main shaft, is provided with the inlet opening near the tail cone end on the described hollow drill, be provided with apopore near the drill bit end, inlet opening and apopore all are communicated with the drilling rod inner chamber, and the inlet opening all supplies to be connected with cooling water source with apopore, and described drill bit tail diameter is greater than the diameter of drilling rod.
Advantage of the present invention is: during work, according to the length adjustment chuck of workpiece and the distance between the centre frame, on the front end centering frame with workpiece, the rear end places on the chuck, rotation hand wheel, main shaft is carried out inching, drill bit is withstood on the workpiece, and fixing motor reducer work on the lathe bed of head of a bed below drives the chuck rotation, the start building part rotation of chuck rotating band, the motor reducer work of lathe bed front end simultaneously drives main axis rotation, and main axis rotation drives tailstock and moves to the workpiece place, drill bit is holed at workpiece, water under high pressure enters in the inner chamber of hollow drill from the inlet opening of hollow drill simultaneously, flows out from apopore then, after depth drill is good, the motor reducer of lathe bed front end works on, and drill bit is withdrawed from workpiece.Because the diameter of drill bit afterbody is greater than the diameter of drilling rod, the high-pressure hydraulic that flows out from the drilling rod inner chamber is flushed to the iron filings that drill bit work produces outside the workpiece, so the cooling of chip removal limit, drill bit edge work limit, chip removal is smooth and easy, and high-pressure cooling water can also be lowered the temperature and plays lubricated effect, good cooling results drill bit, the conserve water resource, process velocity is fast, according to test, can improve 3-5 times, can process the workpiece of random length, in addition owing to be workpiece rotation, thus the product good concentricity that processes, good product quality.
