DETAILED DESCRIPTION OF THE INVENTION

(6) Details and working conditions of a specific device set forth according to the present invention are described below with reference to the drawings.

(7) The device consists of a drilling machine 1, a guide rail I 2, a bottom plate 3, a hydraulic cylinder I 4, a double-shaft air cylinder 5, a positioning lock 6, a fixture I 7, a feeler block 8, a support block 9, a guide post 10, a hydraulic cylinder II 11, a support post 12, a fixture II 13, a sliding plate 14, a guide rail II 15, a hydraulic cylinder III 16, a guide rail III 17 and a hydraulic cylinder IV 18, wherein the bottom plate 3 is fixed above a worktable of the drilling machine 1 by means of the guide rail I 2; the hydraulic cylinder I 4 is also fixed above the worktable of the drilling machine 1, and the output end of the hydraulic cylinder I 4 is connected with a side vertical plate of the bottom plate 3; the double-shaft air cylinder 5 with the output end provided with the positioning lock 6 is fixed on the side vertical plate of the bottom plate 3; the fixture I 7 is installed on a fixed position above the bottom plate 3; the fixture II 13 is fixed above the bottom plate 3 by means of the guide rail II 15; the hydraulic cylinder III 16 is fixed on the side of the bottom plate 3, and the output end of the hydraulic cylinder III 16 is connected with the fixture II 13; the support post 12 with the top end provided with the feeler block 8 is fixed above the sliding plate 14, and the sliding plate 14 is also fixed above the bottom plate 3 by means of the guide rail III 17; the output end of the hydraulic cylinder IV 18 fixed on the side of the bottom plate 3 is connected with the sliding plate 14; the guide post 10 with the left end provided with the support block 9 is matched with the support post 12, the hydraulic cylinder II 11 is installed at the right side of the support post 12, and the output end of the hydraulic cylinder II is connected with the guide post 10.

(8) In the working process, the hydraulic cylinder I 4 pushes out the bottom plate 3 by means of the guide rail I 2; the steering knuckle left workpiece is clamped on the fixture I 7, the right workpiece is clamped on the fixture II 13, the hydraulic cylinder III 16 pushes the fixture II 13 forward by means of the guide rail II 16 until the fixture II contacts the fixture I 7 and stops, at this moment, the double-shaft air cylinder 5 pushes the positioning lock 6 forward to be simultaneously inserted into the fixture I 7 and fixture II 13 so as to fix the positions of the two fixtures, and center lines of four machined holes of the fixed steering knuckle left workpiece and right workpiece are coaxial; the hydraulic cylinder IV 18 pushes the support post 12 onto a corresponding position by means of the guide rail III 17, the hydraulic cylinder II 11 enables the support block 9 to play a role in supporting two symmetric steering knuckle workpieces by means of the guide post 10 to prevent the vibration of cutters when in machining, after the workpieces are fixed, the hydraulic cylinder I 4 withdraws the bottom plate 3, and the drilling machine 1 begins to machine the workpieces.
