Abstract
The utility model relates to an electric lifting cantilever device. An electric push rod is arranged between an upper connecting rod and a lower connecting rod of a quadrangle mechanism. The upper connecting rod is connected with a front end connecting element through a rotary shaft in a rotary mode, the lower connecting rod is connected with a rear end connecting element through a rotary shaft in a rotary mode, the rear end connecting element is connected with a base fixing pipe through a rotary joint, the front end of the push rod is connected with the upper connecting rod through a push rod connecting plate and a pin shaft, and the rear end of a reduction gearbox is connected with the lower connecting rod through a fixing plate at the rear end of the lower connecting rod and a pin shaft. By means of the parallelogram mechanism and the self-lock electric push rod, large load can be achieved. Self lock of the push rod can be achieved within a rated push force range at any position, so that the same cantilever is large in load range and strong in generality, and can stop at any position within a lifting range. Electric lifting and descending of the cantilever are achieved, and labor intensity of operators is greatly reduced.
Description
Technical field
The utility model relates to a kind of Electrical Control of Machinery Tools case, especially a kind of cantilever arrangement of Electrical Control of Machinery Tools case.
Background technology
At present, the jib system of existing machine tool electric control box adopts air spring to support more, as shown in Figure 1, in stationary links 15 fixedly the time, spurring left connecting rod 11 drive entire mechanism by the people 14 moves up and down around the shaft, after the people cancelled motive force, because air spring 13 has certain damping force, mechanism just was parked in corresponding seat.Cause the load-carrying of entire mechanism less because the loading capacity of air spring 13 is less; Because a kind of loading capacity of air spring 13 of specification is certain, so can only mate a kind of loading capacity of electric control box, versatility is poor; And can only manual operation, can not realize automatic lifting.
Summary of the invention
The utility model is that a kind of electric up-down cantilever arrangement will be provided, and is used for solving the technical problem of arm loading capacity, versatility and automatic lifting.
For achieving the above object, technical scheme of the present invention is: a kind of electric up-down cantilever arrangement, comprise quadrangular mechanism, and be characterized in: between the last connecting rod of quadrangular mechanism and the lower link electric pushrod is housed.
Quadrangular mechanism comprises connecting rod, lower link, preceding end connection, back end connection, is rotationally connected with the back end connection by rotating shaft and preceding end connection respectively between last connecting rod and the lower link, and back end connection connects the pedestal stationary pipes by cradle head.
Electric pushrod comprises motor, reduction box and push rod, and wherein, the push rod front end is connected with last connecting rod with bearing pin by the push rod connecting plate, and the reduction box rear end is connected with lower link with bearing pin by lower link rear end fixed head.
Quadrangular mechanism is parallel-crank mechanism.Electric pushrod 4 is the self-locking electric pushrod.
The beneficial effects of the utility model are:
This cantilever arrangement adopts parallel-crank mechanism and self-locking electric pushrod, can realize more stor load-carrying; But this push rod in all self-lockings of seat arbitrarily, makes that same cantilever load-carrying scope is big in the normal thrust scope, highly versatile, and can in range, stop the optional position; Realize the electric up-down of cantilever, greatly reduced operator's labour intensity.
Description of drawings
Fig. 1 is existing jib system structural representation;
Fig. 2 is structural representation of the present utility model
Fig. 3 is electric pushrod structural upright schematic diagram;
Fig. 4 is the quadrangular mechanism schematic perspective view.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment.
To shown in Figure 4, electric up-down cantilever arrangement of the present utility model comprises quadrangular mechanism, electric pushrod 4, rotating shaft 5, cradle head 6, pedestal stationary pipes 7, bearing pin 10 etc. as Fig. 2.
As shown in Figure 2, between the last connecting rod 3 of quadrangular mechanism and the lower link 1 electric pushrod 4 is housed.
As Fig. 2, shown in 3, quadrangular mechanism is parallel-crank mechanism.It comprises connecting rod 3, lower link 1, preceding end connection 2, back end connection 12, is rotationally connected by rotating shaft 5 and preceding end connection 2 and back end connection 12 respectively between last connecting rod 3 and the lower link 1.Back end connection 12 connects pedestal stationary pipes 7 by cradle head 6.Fixedly connected electric cabinet on the preceding end connection 2.
As Fig. 1, shown in 4, electric pushrod 4 is the self-locking electric pushrod.It comprises motor 21, reduction box 22 and push rod 23.Push rod 23 front ends are connected with last connecting rod 3 with bearing pin 10 by push rod connecting plate 8, and reduction box 22 rear ends are connected with lower link 1 with bearing pin 10 by lower link rear end fixed head 9.
When 4 motions of control electric pushrod, electric pushrod 4 drives are gone up connecting rod 3 and 5 are done rotation around the shaft, thereby end connection 2 moves up and down before driving, because the support of lower link 1 is arranged, has guaranteed that preceding end connection 2 remains vertical state (electric cabinet keeps vertical state) in motion process.
The utility model utilizes the flexible of electric pushrod, and the drive parallel-crank mechanism moves reciprocatingly, thereby has realized the lifting (also can stop at an arbitrary position) of cantilever front end.
