Detailed description of the invention
As shown in Figure 1 to Figure 3, a kind of automatic putting down for workpiece sensing tiltedly changes lifting device, comprise crane 5, the two ends of described crane 5 are hinged with pipe link 3 respectively, the end of pipe link 3 is provided with chuck 301, chuck 301 is connected with the trailing arm 1 perpendicular with pipe link 3 by rotational pin 13, the top of described trailing arm 1 is provided with the supporting board 2 for placing workpiece to be detected, lower hinge limited location bar 8, described position-limited lever 8 is provided with the limit base 7 with its sliding connection, and the end of position-limited lever 8 is provided with the rubber sphere 9 be fastened in limit base 7; The lower vertical of described crane 5 is provided with cylinder 6 and at least two telescopic supporting rods, the vertical crank motion of cylinder 6, crane 5 is driven to rotate around the pin jointed end of itself and pipe link 3, and the crank motion of position-limited lever 8 in limit base 7 drives trailing arm 1 untie-sell 13 that rotates to rotate, and then realize the horizontality of supporting board 2 that trailing arm 1 top arranges and the conversion of heeling condition.
The below of above-mentioned crane 5 is separately provided with the permanent seat 4 for fixing cylinder 6 and each telescopic supporting rod, the end of permanent seat 4 is provided with boss, boss is bolted on the workplatform for workpiece sensing, and limit base 7 is bolted on the workplatform for workpiece sensing.Wherein, each telescopic supporting rod forms by pilot bar 10 and with the linear bearing 11 of pilot bar 10 sliding connection, linear bearing 11 is fixed on permanent seat 4, and the floating junction 601 arranged in the end of described pilot bar 10 and cylinder 6 is fixed on the bottom of crane 5.
The present invention mainly for detection of the workpiece lifting on automobile front-rear axle trestle component measuring equipment, especially on position, each hole on detection automobile front-rear axle trestle component and surface profile position Synthesis measuring equipment.The present invention can realize Large heavy workpiece when automatic lifting puts in place, is transferred to by workpiece and tiltedly puts state, simultaneously, horizontality can be reverted to again after lifting workpiece decline, be convenient for measuring and manually pick and place workpiece, alleviating operative's muscle power, and making operating process convenient; Solve the bump injury problem of automobile front-rear axle support, alleviate operative's muscle power simultaneously.
Working process of the present invention is: hand valve control cylinder 6, cylinder rod in cylinder 6 is stretched out, supporting board 2 is driven to rise, position-limited lever 8 and rubber sphere 9 also rise simultaneously, when rising to certain distance, rubber sphere 9 and limit base 7 are adjacent to, and make supporting board 2 continue rising and put into heeling condition in place, be manually placed into by part on supporting board 2; Hand valve control cylinder 6, makes the cylinder rod in cylinder 6 retract, and drive supporting board 2 to decline, rubber sphere 9 and limit base 7 depart from, and make supporting board be raised to position for 2 times and become horizontality, measuring equipment starts to detect part; After detection, hand valve control cylinder 6, makes the cylinder rod in cylinder 6 stretch out, and drive supporting board 2 to rise to heeling condition, manually fetched by part, operation completes.
In the present invention, for improving stability and the safety of whole device, can arrange multiple cylinder in the centre of multiple telescopic supporting rod, the pilot bar 10 in each telescopic supporting rod arranges electromagnet safety lock, the position set by each electromagnet safety lock is not on the same line.Wherein, electromagnet safety lock comprises electromagnet, insurance orifice plate and insurance hole supporting seat, when electromagnet energising is adsorbed with insurance hole supporting seat, do not contact between electromagnet with pilot bar, now, this device is in insurance open mode, and each telescopic supporting rod can free crank motion; When electromagnet dead electricity, insure the locking plate that hole bearing and pilot bar are arranged and withstand mutually, make pilot bar be fixed on certain position and can not move, play safety effect.
This device has following characteristics: (1) mostly is indoor effect due to vehicle maintenance and repair, adopts this device when meeting lifting condition, can save space; (2) operate steadily, symmetrically arranged two supporting boards ensure that the safety of castering action, and the extreme lower position of supporting board is lower, make the chassis of vehicle lower, expand the range of use of this device; (3) compared with screw lifting machine, service life is longer; (4) design of linear bearing and cylinder, is easy to realize overload protection.
