Description
Technical field
The utility model belongs to a kind of centre-drilling hole machine.
Background technology
At present, with lathe, to workpiece centering in batch, comparatively waste time and energy, workman's physical demands is large.Especially for large-scale workpiece, can only use artificial centering, first spile and then progressively expand, not only more waste time and energy, workman's physical demands is large; And quality is difficult to ensure, and speed is slow, efficiency is low, impact is produced.
Summary of the invention
The purpose of this utility model is a kind of centre-drilling hole machine of design, can mechanization, easily various workpiece are got to centre bore, and have simple in structurely, time saving and energy saving, safe and reliable, speed is fast, the high and good advantage of result of use of efficiency.
For this reason, the utility model is mainly comprised of body, hydraulic jack, scroll chuck and motor, middle part is established with the fixing frame plate of working hole in front side, body upper end, the working hole outside of fixing frame plate sets firmly three melon chucks by terminal pad, slide rail is established in the body upper end of the working hole inner side of fixing frame plate, on slide rail, be slidably equipped with slide, the upper end of slide is installed with motor, motor wheel setting corresponding to working hole, motor wheel is connected center bit rear end by adapter sleeve with drill chuck head rod, body upper end rear side is established hydraulic jack, and the piston rod of hydraulic jack is connected with the rear end of slide.The front side of described body is provided with operation board.The rear side lower end of described body is provided with oil pump case.Said structure design has realized the purpose of this utility model.
The mechanization of the utility model energy, gets centre bore to various workpiece easily, has simple in structurely, time saving and energy saving, safe and reliable, and speed is fast, the high and good advantage of result of use of efficiency.The utility model only needs 1 people to fulfil assignment according to statistics, and efficiency improves more than 20 times, has good result of use.
Accompanying drawing explanation
Figure is structural representation of the present utility model.
The specific embodiment
As shown in the figure, a kind of centre-drilling hole machine, is mainly comprised of body 13, hydraulic jack 1, scroll chuck 10 and motor 3.Middle part is established with the fixing frame plate 11 of working hole 8 in front side, body upper end.The working hole outside of fixing frame plate sets firmly three melon chucks by terminal pad 9.Slide rail 14 is established in the body upper end of the working hole inner side of fixing frame plate, is slidably equipped with slide 15 on slide rail, and the upper end of slide is installed with motor.Motor wheel setting corresponding to working hole, motor wheel 4 is connected center bit 7 rear ends by adapter sleeve 5 with drill chuck head rod 6.Body upper end rear side is established hydraulic jack, and the piston rod 2 of hydraulic jack is connected with the rear end of slide.The front side of described body is provided with operation board 12, establishes control circuit in operation board, to control the operation of motor rotation and hydraulic jack.The rear side lower end of described body is provided with oil pump case 16, and the operation that oil pump case is hydraulic jack provides power.
During use, workpiece to be processed is fixed on three melon chucks.Open motor and hydraulic jack, the rotation of driven by motor center bit, the front end of center bit is aimed at workpiece to be processed, and the piston rod of hydraulic jack ejects lentamente slide is moved ahead along slide rail, drives motor and center bit on it also to move ahead, and completes boring.Then, counter motion, completes process.
In a word, the mechanization of the utility model energy, gets centre bore to various workpiece easily, has simple in structurely, time saving and energy saving, safe and reliable, and speed is fast, the high and good advantage of result of use of efficiency.
