Description
Technical field
The utility model relates to a kind of electric scissor jacking system, is used for specifically comprising on the automatic production line that auto production line realizes that mechanical automation carries, and workpiece is delivered to the height of appointment, belongs to mechanical automation conveying technology field.
Background technology
At present, in comprising the automatic production line of car production, workpiece (automobile component) will be changed at various height, and this just need use a kind of process equipment---scissor lift arrangement of special use.Scissor lift arrangement can be delivered to workpiece the height of appointment with workpiece according to different technological requirement height.Before the utility model was made, in prior art, the scissor lift arrangement of use mainly adopted fluid pressure drive device.Fluid pressure drive device is cut the technological requirement that an arm-tie reaches the lifting work piece platform by Driven by Hydraulic Cylinder, and this driving needs attendant equipment: as fuel tank, Hydraulic Pump, filter screen; A cost of investment height, in use the major defect of Cun Zaiing is that the speed of lifting is inhomogeneous; Protection is undesirable in the lifting process; the pollution of hydraulic pressure machine oil has brought the dangerous of operationlocation; and safeguard relatively difficulty; the restriction ratio that the initial angle α of shear pull bar is subjected to oil cylinder is bigger; so liftoff height of initial condition bench board that hoists; so just be unfavorable for to reprint starting shipment of thing, thereby can not satisfy in the automatic assembly line highly conditional special technological requirement.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby provide a kind of electric scissor jacking system, its utilization has the reducing motor of drg, drive screw pair, thereby the nut on the pulling screw mandrel drives take-up pulley, take-up pulley is made relative rolling touch in cutting an arm-tie, makes the lifting of lifting work piece platform reach the requirement that hoists and descend; Defectives such as the speed that can effectively overcome the hydraulic-driven jacking system is inhomogeneous, and the protection in the lifting process is undesirable, and the damage ratio (DR) of machine oil is more serious, safeguards inconvenience, and the initial angle α of shear cam is bigger.
Main solution of the present utility model is achieved in that
The utility model adopts and connects lower shearing plate in lower support one end both sides by fastener, fix with cutting an arm-tie in the middle of two lower shearing plates, lifting work piece platform one end both sides connect upper shearing plate by fastener, fix with cutting a pull bar in the middle of two upper shearing plates, the lower shearing plate other end is installed between the other end raceway of lower support by roll wheel assembly up and down, the upper shearing plate other end is installed between the other end raceway of lifting work piece platform by roll wheel assembly up and down, and tween drive shaft and last lower shearing plate 13,14 are hinged; Driven unit relies on tween drive shaft to be installed on the lower shearing plate, and last lower shearing plate 13,14 is connected with take-up pulley assembly, driving screw pair with the lifting work piece platform respectively, and is connected with driven unit.
Driving screw pair is the ball form.In the middle of driving screw pair, switch testing agency is set.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Because adopted the curve shear of cam-type, thereby realized the at the uniform velocity lifting of lifting work piece platform, the speed that can effectively overcome the hydraulic-driven jacking system is inhomogeneous, the protection in the lifting process is more satisfactory; After the supporting use of reducing motor of this curve shear and band brake, can realize lifting work piece platform location, optional position in the middle of adjustable height simultaneously, accurate positioning is not sunk; The work initial angle α of lifting work piece platform is extremely low, and minimum of alpha can reach 5～6 °; Also overcome simultaneously the pollution that oil hydraulic system exists, it is also easier to safeguard, and the cost of equipment is lower.

The specific embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
The utility model mainly by lower support 1, lifting work piece platform 2, driven unit 3, take-up pulley assembly 4, drive screw pair 5, up and down roll wheel assembly 6, bearing pin 7, pad 8, axle head clamp 9, cut an arm-tie 10, cut a pull bar 11, switch testing agency 12, go up compositions such as lower shearing plate 13,14 and axis.
The utility model lower support 1 is made by steel frame, and installs on the ground with pressing plate.Fix with cutting an arm-tie 10 in the middle of connecting bearing pin 7 in the fastener (N), pad 8, axle head clamp 9 connection lower shearing plates 14, two lower shearing plates 14 in lower support 1 one end both sides, and keep spacing.It is middle fixing with cutting a pull bar 11 that lifting work piece platform 2 one end both sides connect upper shearing plates 13, two upper shearing plates 13 by bearing pin 7, pad 8, axle head clamp 9 in the connection fastener (N), and the maintenance spacing.Lower shearing plate 14 other ends are installed between the other end raceway of lower support 1 by roll wheel assembly (M) 6 up and down, upper shearing plate 13 other ends are installed between the other end raceway of lifting work piece platform 2 by roll wheel assembly (M) 6 up and down, tween drive shaft 15 is fixed on the drop-gear box, and the other end and last lower shearing plate 13,14 are hinged; The reducing motor and the transmission gearbox driven unit 3 that have drg rely on tween drive shaft 15 to be installed on the lower shearing plate 13,14, make it become the scissors support component of one pair of folding with convenience.Last lower shearing plate 13,14 is connected with take-up pulley assembly 4, driving screw pair 5 with lifting work piece platform 2 respectively, and is connected with driven unit 3.Driven unit 3 drives two of transmissions and drives screw pair 5 and take-up pulley assembly 4, take-up pulley assembly 4 and last lower shearing plate 13,14 relative rolling touch.Driving screw pair 5 is the ball form.Switch testing agency 12 is put in installing in the middle of driving screw pair 5.
