Specific implementation mode
The invention will be further described below in conjunction with the accompanying drawings.
Referring to Fig.1-10, what a kind of orthogonal cutting force test device, combining with digital control Milling Machining Center and dynamometer carried out
Structure design.Referring to Fig.1-10, which includes rack 1, main shaft 2, boring cutter handle 3, angle lathe tool 4, thin-wall workpiece 5, three
Grab chuck 6, connecting plate 7, dynamometer 8, pressing plate 9, workbench 10, charge amplifier 11, data collecting card 12 and computer 13.Institute
Main shaft 2 is stated in rack 1, the boring cutter handle 3 is mounted on 2 lower end of main shaft.The angle lathe tool 4 is installed on boring cutter handle 3
It installs in square hole 16, passes through the interior hexagonal flush end holding screw 14 of threaded hole 17 and the interior hexagonal flush end holding screw of threaded hole 18
15 so that the angle lathe tool 4 is fixedly connected with the boring cutter handle 3.The bottom of the dynamometer 8 passes through with the workbench 10
Trapezoidal bolt 20 on the pressing plate 9 across hole 19 is fixedly connected with hex nut 21.The connecting plate 7 is mounted on the dynamometry
On instrument 8,7 top panel of the connecting plate has counter sink 22, the dynamometer 8 to have tapped blind hole above, pacify on the counter sink 22
Equipped with the hexagon socket cap head screw 23 to connect the connecting plate 7 and the dynamometer 8, the three chucking chuck 6 is installed
