Abstract
The invention provides an excircle machining mechanism which can machine overlength workpiece with low energy consumption, long service life and high machining precision and comprises an inner cyclone milling head and a primary motor connected with the cyclone milling head to drive for rotation around the y axis. The inner cyclone milling head is rotatably connected on a supporting seat. The primary motor and the supporting seat are fixed on a slide board which is in sliding connection with the engine base along the z axis direction vertical to the y axis. The slide board is connected with the transmission mechanism driving the slide board to slide along the z axis. An engine base is arranged on an x axis supporting plate moveable along the x axis direction vertical to the y axis. When processing the excircle, the workpiece is stationary, the inner cyclone milling head rotates at high speed (around y axis), the workpiece extending into the inner cyclone milling head is stationary and meanwhile inner cyclone milling head translates on two directions (x axis and z axis directions) vertical to the rotor axis, thus machining the excircle of the workpiece.
Description
Technical field
The present invention relates to the machining technique field, belong to external cutting machinery, specifically, is a kind of Workpiece non-rotating excircle machining mechanism.
Background technology
Existing cylindrical machining tool adopts the processing mode that cutter is static, workpiece rotates mostly.The speed of mainshaft of machine tool is about 1000 rev/mins, so not only energy consumption is big, and also there is very big influence in life-span of lathe, secondly during the high rotating speed cutting of engine lathe, the mechanical oscillation that produce are also bigger, will certainly very big influence be arranged to the precision and the surface roughness of workpiece.If workpiece overlength (as the main hurdle rope of bridge spanning the sea) or super large (as the bent axle of big marine diesel engine, tens meters long, tens tons weights being arranged), engine lathe is just powerless.
Summary of the invention
The purpose of this invention is to provide that a kind of energy consumption is little, the life-span is long, vibration is little, machining accuracy is high, the excircle machining mechanism of energy processing super long workpiece.
Workpiece non-rotating excircle machining mechanism of the present invention, cyclone milling head and being connected with interior cyclone milling head in comprising to drive its main motor around the rotation of y axle, interior cyclone milling head is rotatably connected on the supporting seat, on main motor and the supporting seat fixed glides, slide plate becomes to be slidingly connected with support on perpendicular to the z direction of principal axis of y axle; It is connected slide plate and drive along transmission mechanism that the z axle slides; Support is arranged on can be along perpendicular on the x axle supporting plate that moves on the x direction of principal axis of y axle.
The present invention is when processing excircles, workpiece is static, and interior cyclone milling head is (around the y axle) rotation at a high speed, and the workpiece in extending in the cyclone milling head is static, cyclone milling head is gone up translation at the both direction (being x axle and z direction of principal axis) perpendicular to its rotating shaft simultaneously, gets final product the cylindrical of processing work like this.Cutter among the present invention (interior cyclone milling head) is rotation at a high speed, and the relative compensating motion by X-axis, Z axle carries out machining, so that machine power consumes is little, has only 1/3～1/4 of corresponding machine power; That the present invention vibrates is little, machining accuracy is high.And the speed of mainshaft of traditional common machine machining tool is so not only big to the lathe loss about 1000 rev/mins, and the mechanical oscillation of generation are also bigger, and the life-span and the machining accuracy of lathe also had very big influence.The processing mode of the Workpiece non-rotating cutter high-speed cutting that we adopt, because machine spindle speed is very little or not running, this has reduced the loss of lathe itself to a great extent.
As further improvement, x axle supporting plate is arranged on the y axle supporting plate (lathe saddle) that can move along the y axle.The y axle is the direction of motion of lathe saddle, and the interlock of crossing the y direction can machining screw.
As further improvement, transmission mechanism is feed screw nut's transmission mechanism, and slide plate is fixedlyed connected with nut, is connected on first drive motor with the nut fit screw rod, and first drive motor is arranged on the support.
Description of drawings
Fig. 1 is that master of the present invention looks schematic diagram.
Fig. 2 is the schematic top plan view of Fig. 1.
The specific embodiment
Workpiece non-rotating excircle machining mechanism shown in Fig. 1,2, four are fixed on interior week of the milling cutter fixed cover 2 that extends along y direction of principal axis (direction of motion of lathe saddle) to interior Whirlwind milling cutter 1, and interior Whirlwind milling cutter 1 and milling cutter fixed cover 2 have constituted interior cyclone milling head.The milling cutter fixed cover is rotatably connected on the supporting seat 3, on main motor 4 and supporting seat 3 fixed glides 5.The motor gear 6 of main motor 4 and carrier gear 7 engagements, carrier gear 7 and gear wheel 8 engagements, with the periphery engagement of milling cutter fixed cover 2.Main motor 4 rotates, and rotates around the y axle in the xoz plane by motor gear 6, carrier gear 7, gear wheel 8 drive milling cutter fixed covers 2 and interior Whirlwind milling cutter 1.
Respectively there are four slide blocks 9 both sides of slide plate 5, and the slide block 9 of both sides is slidingly connected with two one slide rails 10 that extend along the z direction of principal axis that are fixed on support 12 both sides respectively.Slide plate 5 is fixedlyed connected with nut 11, and the screw mandrel that is parallel to the z axle 13 that cooperates with nut is connected on first drive motor 14, and first drive motor 14 is arranged on the support 12.
Drive y axle supporting plate (with and on x axle supporting plate, support 12, slide plate 5, interior cyclone milling head) belong to prior art along the mechanism that the y axle moves, not shown.
The present invention is by having following function:
1, interior Whirlwind milling cutter 1 itself rotates around the y axle, and can processing excircles by x direction of principal axis and the axial interlock of z.
2, interior Whirlwind milling cutter 1 itself rotates around the y axle, and can machining screw by x direction of principal axis, y direction of principal axis and the axial interlock of z, and the y direction of principal axis is the direction of motion of lathe saddle.
The present invention has adopted workpiece static, cutter rotates at a high speed, the relative compensating motion of X-axis, Y-axis, Z axle carries out machining, so it is little that machine power consumes, as long as 1/3～1/4 of corresponding machine power, and the machined of traditional approach needs the speed of mainshaft of lathe about 1000 rev/mins, and so not only energy consumption is big, and also there is very big influence in life-span of lathe.When secondly the high rotating speed of engine lathe cut, the mechanical oscillation of generation were also bigger, will certainly very big influence be arranged to the precision and the surface roughness of workpiece, and mechanical oscillation of the present invention are little, the machining accuracy height.And Whirlwind milling cutter only needs about 10000 yuan when carrying out screw chasing in of the present invention.
The present invention adopts workpiece static, the processing mode that cutter rotates at a high speed, because machine spindle speed is very little or not running, this has reduced the loss of lathe itself to a great extent.
The present invention can processing super long workpiece (as the main hurdle rope of bridge spanning the sea) or super large, overweight workpiece (as the bent axle of big marine diesel engine).
