Description

Boring machine applicable to scene processing

Affiliated technical field

The utility model relates to a kind of boring device that requires concentric bore hole.Especially a kind of Boring machine applicable to scene processing.

Background technology

At present, bore hole processing, the most employing processed on boring machine, need dismantle workpiece to be machined, is transported to job shop then, increased process-cycle and processing charges.

The ZL of the State Intellectual Property Office of the People's Republic of China patent No.: 02233171.9 discloses a kind of Boring machine.This Boring machine has motor fixed rack and motor, also is provided with the main frame that comprises transmission component and cutter shaft, and rotating speed of motor is passed to the sheave of main frame, in connect sleeve, the workpiece reinforced liner constitutes jointly.This machine is assembled jointly by several parts, and cutter shaft adopts nut to fix with being connected of main frame.Must get up motor, main frame, the assembly unit of workpiece reinforced liner during construction, it is comparatively loaded down with trivial details that transportation and dress are driven operation, the weight macrostructure complexity of complete equipment; Because workpiece reinforced liner, motor and main frame are that the volume that independently separates is bigger, and this machine employing workpiece reinforced liner fixes workpiece, causes the machine bigger operating space of having limited that takes up room.The motor that this machine adopts is the motor of fixed rotating speed, can only realize two grades of rate conversion by changing the belt sheave, does not satisfy the requirement to the boring bar cutting rotational speeds when bore hole of the different apertures of unlike material.This machine adopts workpiece reinforced liner to fix workpiece and moves up and down and realize centering by adjusting this rack screw, and the adjustment of centering can't guarantee, and is slow and precision is not high to medium velocity.And owing to this small product size is bigger, the processing space during to installation requires big, and therefore in most cases, workpiece to be machined need disassemble from main equipment again and process.

Summary of the invention

In order to overcome existing Boring machine complex operation, be unfavorable for on-the-spot less space processing, and speed is regulated and the low deficiency of accuracy of alignment, the utility model provides a kind of Boring machine, this Boring machine can not only be operated in the less at the scene space, and can satisfy of the requirement of different apertures various material, and guaranteed the precision of bore hole centering better to cutting speed.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of Boring machine of on-the-spot processing, by support, cutterhead and the centralizer of a boring bar and a fixation, the casing, boring bar drive motors, polished rod and the screw mandrel that are made of bearing, gear and feeding motor constitute jointly.Wherein support, cutterhead and centralizer are contained on the boring bar, boring bar passes casing top and is connected with drive motors by Mohs vertebra degree handle, drive motors connects slide block by backing plate and links to each other with two feed rods, and feed rod passes slip front and links to each other with lower box, and the polished rod rear end links to each other with the handwheel fixing support rack.Drive motors and casing fuse, and this machine adopts front end to support directly to link to each other with workpiece, and operation is simplification more, has saved the operating space greatly, makes machine more be tending towards portable.The boring bar drive motors adopts two grades of stepless speed regulations, transfers and turns round motor, thereby guaranteed the requirement of different apertures unlike material to rotating speed. only need to regulate the conversion that turn-knob can be realized speed and torque.Centralizer adopts the vertebra body, can use this device that boring bar is carried out rapid centering.

The beneficial effects of the utility model are, can directly be welded on the workpiece to be machined, take very little operating space, compact conformation.Feeding and boring bar cutting speed can be adjusted according to pore size and material.Fast to medium velocity, and the precision height, simple to operate.
