Description

A kind of mobile adjustable lifting workbench

Technical field

The present invention relates to a kind of workbench, especially a kind of mobile adjustable lifting workbench belongs to machine-building skill Art field.

Background technique

In machine industry, one operating procedure of packaging technology is more, larger workload work, existing machinery assembling Technique will use driving to sling components from material cycling area and be transported to assembling station, and the installation position of part is adjusted by driving It sets, finally completes assembling and adjustment.It is bigger using the driving some small-sized components workloads of handling, and entirely assembled Journey is longer to the holding time of driving, affects the lifting and handling work of other large parts, will necessarily cause lifting The raising of machine job costs and the waste of resource, in addition, using train operation adjustment components installation site when cannot adjust at random, Adjustment precision is poor, uses inflexible.

Summary of the invention

The object of the present invention is to provide it is a kind of it is small in size, light-weight, structure is simple, can satisfy small spatial dimension and flexibly move Dynamic lifting requirements, and the safe and reliable adjustable lifting workbench of movable type.

In order to achieve the above object, the basic scheme of the mobile adjustable lifting workbench of the present invention are as follows: including being fixed on Column (26) in moving trolley (1), the upper end support of the column have the pedestal (20) of vertical shaft (19), the pedestal Two sides support the runner of at least a pair of of horizontal interval distribution, the runner and mutually connected upper and lower rails (7,8) structure respectively At moving horizontally pair;Capstan winch (13-1) is installed in one end of the upper rail, and other end support pulley (13-2), the capstan winch around There is the cable (13-3) for suspending hook (13-4) in midair by pulley.

When work, after moving trolley is preliminary in place, the cantilever-shaped upper and lower rails of the adjustable lifting workbench of movable type can be with The flexible displacement of capstan winch derricking gear horizontal direction is driven, upper and lower rails then can be around 360 ° of pedestal any rotations, so as to side Just the accurate adjustment of Hoisting Position is realized.

The present invention further improves, and placement has the clump weight of horizontal direction freedom degree in the moving trolley (28), hinged balancing pole (27) on the pedestal, the upper end of the balancing pole, which has to constitute with the sliding pin being placed on guide rail, to be moved Secondary upper guide groove is moved, the lower end of the balancing pole has to constitute with the sliding pin being mounted on clump weight (28) leads under prismatic pair Slot.

Therefore, when upper and lower rails indexing, clump weight is accordingly indexable;When upper and lower rails are when a certain range is stretched, match The displacement of pouring weight respective opposed keeps supporting gravity to be substantially in moving trolley supporting surface, avoids inclining so as to adjust automatically It turns over, it is ensured that safety.

Further, the column is by the cylinder being fixed on bottom plate and the internal screw thread plug screw group being fixed at the top of cylinder At.Be connected stiffener plate between the bottom plate and cylinder.

Further, the fixed bearing block with vertical undergauge stepped hole in the plug screw.

Also further, the lower end of the bearing block installs shaft by transverse bearing and traps, the upper end that the shaft is trapped Thrust axis is respectively provided between face and the undergauge step lower end surface and undergauge step upper surface and the lower end surface of pedestal of bearing block It holds.

Further, lower end and shaft are inserted in the inner hole of the pedestal trap be connected and the vertical shaft of axial constraint.

Another further, the runner is moved embedded in the interior level that constitutes of the caulking groove of mutually connected upper and lower rails respectively up and down Dynamic pair.

Detailed description of the invention

In order to illustrate more clearly of technical solution of the present invention, the attached drawing of preferred embodiment is given below.

Fig. 1 is the structural schematic diagram of the embodiment of the present invention one.

Fig. 2 is the A-A cross-sectional view of Fig. 1.

Fig. 3 is the B-B cross-sectional view of Fig. 1.

Fig. 4 is the column supporting structural schematic diagram of Fig. 1.

Specific embodiment

Embodiment one

The adjustable lifting workbench of the movable type of the present embodiment is as shown in Figures 1 to 4, and column 26 is fixed on moving trolley 1 On, upper end support has the pedestal 20 of vertical shaft 19, and specific structure is referring to Fig. 3 and Fig. 4, and column 26 is by being welded on bottom plate Cylinder 26-2 on 26-4 and the internal screw thread plug screw 26-1 being welded at the top of cylinder 26-2 composition, bottom plate 26-4 and cylinder 26- Stiffener plate 26-3 is welded between 2.The fixed bearing block 22 with vertical undergauge stepped hole, bearing block 22 are screwed in plug screw 26-1 Lower end shaft installed by radial needle bearing 24 trap 23, shaft is trapped 23 upper surface and the undergauge step of bearing block Thrust bearing 21 is respectively provided between lower end surface and undergauge step upper surface and the lower end surface of pedestal 20, in the inner hole of pedestal 20 Inserting lower end is trapped the vertical shaft 19 of simultaneously axial constraint of being connected by fastening screw nut and shaft, thus constitute rotate freely, The reliable column supporting structural of load.Due to the outer ring radial positioning by needle bearing, bearing is used to support as rotation, because This frictional resistance is small, alleviates the abrasion of rotary part.

The runner 15 that the two sides of pedestal 20 support a pair of of anterior-posterior horizontal to be spaced apart respectively, specific structure as shown in Fig. 2, The pin shaft 17 stretched out in the lateral aperture of pedestal 20 by the fixed both ends of the tight bolt 14 of branch, 17 both ends of pin shaft are installed as runner 15 Bearing, and by 16 axially position of spacer.Runner 15 passes through cover board 11 and link block 4 mutually embedded in both ends respectively up and down respectively In the caulking groove of connected upper and lower rails 7,8, composition moves horizontally pair.One end of upper rail 7 capstan winch 13- is installed by capstan winch seat 5 1, and the other end supports pulley 13-2, capstan winch 13-1 to be wound with the cable by pulley 13-2 suspention hook 13-4 by pulley base 9 13-3 forms lifting component 13.

When assembling, moving trolley is pushed into station attachment, workpiece to be assembled is sling by hand capstan, it can be by leading The flexible displacement of rail horizontal direction and organically combined around 360 ° of rotations of pedestal, conveniently realize workpiece is accurately hung to it is any Required assembled position, then control capstan winch and fall.

Embodiment two

The adjustable lifting workbench of the movable type of the present embodiment is as shown in figure 5, with embodiment one except that movement is small Placement has the clump weight 28 of horizontal direction freedom degree, hinged balancing pole 27 on pedestal 20, the upper end tool of the balancing pole 27 on vehicle Have and the sliding pin that is placed on upper rail 7 constitutes the upper guide groove of prismatic pair, lower end has and the sliding pin that is mounted on clump weight 28 Constitute the lower guide channel of prismatic pair.

In this way, clump weight is accordingly indexable when the workpiece sling is with upper and lower rails indexing;When workpiece is stretched with upper and lower rails When contracting, the displacement of clump weight respective opposed, therefore can remain that supporting gravity is in moving trolley supporting surface, even if part It is heavier, also ensure that handling transfer safety guarantees safety while meeting small spatial dimension conscientiously and flexibly moving lifting requirements Reliably.
