Abstract
The invention relates to the technical field of steering knuckles, in particular to a machining method for a back milled plane of a steering knuckle. The method comprises the steps that a clamp is horizontally installed on a worktable of a VMC1165B vertical machining center, a VMC1165B machining center main shaft is connected to a cutter handle, the cutter handle is connected with a 90-degree angle head, and the 90-degree angle head is provided with a face milling cutter to achieve angle switching machining; and finally, the steering knuckle to be machined is positioned through a positioning base and an angular orientation positioning base, so that the steering knuckle is completely positioned, clamping is achieved through motion of a hydraulic oil cylinder, the machining program of the VMC1165B vertical machining center is started, and machining of the steering knuckle is achieved. The machining method has the advantages of increasing the machining speed, improving the machining plane quality, reducing abrasion of a machine tool, prolonging the service life of the machine tool and the like.
Description
Technical field
The present invention relates to knuckle manufacture field, a processing method for knuckle back of the body milling flat (lower control arm installing hole counterbore circumferential plane) specifically, the method is by changing process tool---and on angle head, the mode of loading end milling cutter module realizes processing.
Background technology
Knuckle is one of major part on steering axle of automobile, and vehicle steadily can be made to travel and sensitive transmission travel direction, and the function of knuckle bears automotive front load, support and drives front-wheel to make motor turning around stub rotation.Under motoring condition, it subjects changeable shock loading, therefore, requires that it has very high intensity.
The mode of current existing processing knuckle lower control arm installing hole plane (back of the body milling flat) is that employing two cutters complete, and one is that another cutter processes upper plane with anti-scraper with three sword wire rod quality milling lower planes cutter
,because this face is counterbore circumferential plane, not continuous level, three sword wire rod quality cannot be used to process, anti-scraper must be used to process.But, use anti-scraper to add and there is drawback man-hour, be in particular in: 1., processing beat long, in order to ensure machined surface roughness; 2., to make in anti-scraper process machine tool chief axis bear lower pulling force large, large to machine tool chief axis wearing and tearing, affects lathe service life.
Above current processing knuckle lower control arm installing hole, counterbore circumferential plane such as Fig. 1 illustrates, knuckle installation way is vertical, and cutter is stretched into by machining hole, instead scrapes interpolation milling counterbore circumferential plane.Former processing mode loads anti-scraper to process counterbore circumferential plane by main shaft, and its efficiency is low, and beat is long, and comparatively serious to machine tool chief axis wearing and tearing.
Summary of the invention
The object of the invention is the problem solving counterbore circumferential plane difficulty above processing knuckle lower control arm installing hole, realize angle change by loading an angle head at machine tool chief axis, carry out ream milling flat by installation end milling cutter on angle head.
The object of the present invention is achieved like this, and the method comprises the following steps:
1., clamp body 1 level is arranged on the workbench of VMC1165B vertical machining centre, described clamp body 1 is by clamp bottom board 6, be arranged on two angle positioning seats 10 on base plate 6, two clamp systems be arranged on base plate 6 are formed, described clamp system is by positioning seat 7, is arranged on the hydraulic jack 8 in positioning seat 7 and the pressing plate 9 be arranged on hydraulic jack 8 is formed, and wherein said clamp bottom board 6 is bolted installation and is fixed in VMC1165B vertical machining centre;
2., by VMC1165B machining center main shaft connect handle of a knife 5, handle of a knife 5 connects an angle of 90 degrees degree head 4, and on described an angle of 90 degrees degree head 4, load terminal milling cutter 3 realizes the processing of angular transition;
3., by knuckle 2 to be processed by positioning seat 7 and angle positioning seat 10 location, knuckle is located completely, realize clamping by the action of hydraulic jack 8, start the procedure of VMC1165B vertical machining centre, realize the processing of knuckle.
Advantage of the present invention and effect are:
1, the inventive method realizes angle change by the angle head loading 90 degree at machine tool chief axis, carrys out ream milling flat by installation end milling cutter on angle head, and processing beat is shorter, and machined surface quality is high, processes easy to adjust.
2, the inventive method counterbore periphery rugosity is good, and Tool in Cutting power is low, on machine tool chief axis wearing and tearing without impact, improves product quality and also improves output.
3, the inventive method changes machining angle by the mode of main shaft load angle head, can realize using end mill(ing) cutter processing plane, improves process velocity, improves processing plane quality, reduces lathe wearing and tearing, improves lathe service life.
