Drilling device for wheel insert

[0014] The details and working conditions of the specific device proposed according to the present invention will be described below in conjunction with the accompanying drawings.

[0015] The device consists of frame 1, lifting cylinder 2, lifting column 3, guide sleeve 4, base plate 5, guide rail 6, left slide plate 7, left bearing seat 8, left shaft 9, rack 10, gear 11, drill bit 12, power head 13. Horizontal sliding table 14, vertical sliding table 15, servo motor Ⅰ16, servo motor Ⅱ17, mandrel 18, tray 19, right shaft 20, right bearing seat 21, clamping cylinder 22, right sliding plate 23 and servo motor Ⅲ24 The lifting cylinder 2 is fixed on the bottom of the frame 1, the output end of the lifting cylinder 2 is connected to the bottom of the lifting column 3; the tray 19 is fixed on the upper end of the lifting column 3, and the mandrel 18 matched with the center hole of the wheel is fixed on the top of the tray 19 The guide sleeve 4 matched with the lifting column 3 is installed below the base plate 5; the lower end is fixed with a rack 10, and the left slide plate 7 with a left bearing seat 8 is fixed at the upper end through the guide rail 6 and fixed above the base plate 5; the upper end is fixed with a V-shaped roller. Two left shafts 9 are fixed in two left bearing blocks 8 by bearings.

[0016] The right end is fixed with the horizontal sliding table 14 of the servo motor II 17, which is fixed on the top of the frame 1; the upper side is fixed with the servo motor I 16, and the lower part is fixed with the vertical sliding table 15 of the power head 13, which is installed on the horizontal sliding table 14, and the drill bit 12 is installed At the output end of the power head 13.

[0017] The right bearing seat 21 is fixed on the top, and the right slide plate 23 of the servo motor III 24 is fixed on the bottom, which is fixed above the bottom plate 5 through the guide rail 6; two right shafts 20 with V-shaped rollers are fixed on the upper end, and are fixed on the two right bearing seats through bearings In 21; the output rod of the clamping cylinder 22 installed on the side of the frame 1 is connected with the right slide plate 23, and the synchronous clamping movement of the left shaft 9 and the right shaft 20 to the wheels is realized by the rack 10 and the gear 11.

[0018] The clamping cylinder 22 enables the four V-shaped rollers to realize the axial positioning of the wheels through the rack 10 and the gear 11, and the mandrel 18 realizes the radial positioning of the wheels.

[0019] During the working process, the sensor makes the initial positioning of the wheel, the clamping cylinder 22 makes the four V-shaped rollers realize the axial positioning of the wheel through the rack 10 and the gear 11, and the lifting cylinder 2 makes the mandrel 18 realize the alignment through the lifting column 3 Radial positioning of the wheels. Servo motor III 24 drives the wheel to rotate, and the sensor stops after detecting the position of the valve hole of the wheel, and the positioning of the drill bit is realized through the horizontal slide 14 and the vertical slide 15.
