Embodiment
This automatic adjustment measurement mechanism being used for automobile drum brake comprises frame 1, longitudinal lift servo motor 2, drive lead screw 3, brake level drag hook 4, Work-sheet pressing cylinder 5 and adjustment measuring appliance.Frame 1 is provided with top board 7 by back up pad 6, top board 7 is equipped with longitudinal lift servo motor 2; The top board 7 of longitudinal lift servo motor 2 both sides is symmetrically installed with Work-sheet pressing cylinder 5; Be provided with Work-sheet pressing plate 8 below back up pad 6, Work-sheet pressing plate 8 be symmetrically installed with connecting rod 9, one end of connecting rod 9 to extend to above back up pad 6 and is connected with the piston rod of Work-sheet pressing cylinder 5.The lower surface symmetria bilateralis of Work-sheet pressing plate 8 is provided with servo-operated mechanism B10, servo-operated mechanism B10 is separately installed with adjustment measuring appliance.
Adjustment measuring appliance is made up of measuring head 11, displacement transducer 12 and erecting frame 13, erecting frame 13 is provided with adjustment sounding rod 14, adjustment sounding rod 14 is equipped with displacement transducer 12, one end of adjustment sounding rod 14 extends to erecting frame 13 outer end, and adjustment sounding rod 14 termination extending to erecting frame 13 outer end is provided with measuring head 11 by regulating spring 15.
Work-sheet pressing plate 8 is rectangular parallelepiped, and the Work-sheet pressing plate 8 between servo-operated mechanism B10 is provided with workpiece hole (not shown).
Be provided with installing plate 16 between connecting rod 9 above Work-sheet pressing plate 8, below back up pad 6, installing plate 16 is connected with longitudinal lift servo motor 2 by drive lead screw 3; The lower surface of installing plate 16 is provided with brake level drag hook 4 by servo-operated mechanism A17.
This automatic adjustment measurement mechanism straddle mounting for automobile drum brake is in the production line of automobile drum brake; Each component actuation is by the control of program control device.Longitudinal lift servo motor 2 is for the knee-action of brake level drag hook 4, and servo-operated mechanism A17 is used for the left and right displacement of brake level drag hook 4.During work, the accompany frock loading drum brake product (workpiece) is transported to this and automatically adjusts below measurement mechanism by streamline, and the holder then below streamline rises cylinder and held up by accompany frock,
lock-up cylinderaction, by equal height cushion block plug under holder lift slab, holder rises cylinder, falls on holder lift slab, and on holder lift slab, two register pins insert on accompany frock plate and accurately locate, and product locking has been located.
