Abstract

The invention discloses process equipment for installing and welding a backboard of a dumper, relating to the technical field of dumper manufacturing. The process equipment comprises a platy welding platform, wherein positioning blocks are arranged on at least three side edges of the welding platform; the positioning block on at least one side edge of two opposite side edges is a moveable positioning block; the welding platform is connected with a support frame through a hinged shaft; and a lifting device is installed at the bottom of the welding platform. Compared with prior art, the process equipment disclosed by the invention can solve the problems that size and quality of the backboard of a middle door of a reinforced door of the dumper during manufacturing are difficult to ensure, products of same batch are poor in consistency and positioning takes time and labor.

Description

Plate assembly welding technique equipment behind the dumper

Technical field

The present invention relates to dumper manufacturing technology field, especially a kind of process equipment that is used to make plate behind the reinforced door in door of dumper.

Background technology

At present, along with the development of national economy, the market demand that domestic special-purpose vehicle industry has also obtained great development, particularly dumper, engineering dump truck heightens; And the making of plate behind the reinforced door in door of dumper is to rely on tape measure to position, and is more time-consuming; Size cannot say for sure to demonstrate,prove, and poor with batch consistency of product, and quality also is difficult to guarantee; Need debug behind the plate assembly welding behind the reinforced door in door, need loop wheel machine that the back plate is sling during debugging, then the back plate is fixed by welding on the jig limit; Debug, this kind mode was both required great effort again, and was consuming time again; And when using crane electromagnet to pick up the back plate, back plate can produce flexural deformation, has influence on the quality of back plate.

Summary of the invention

The present invention provides plate assembly welding technique equipment behind a kind of dumper, it can solve prior art after making the reinforced door in door of dumper during plate size, quality cannot say for sure card, and poor with batch consistency of product, the time-consuming problem of location effort.

In order to solve the problems of the technologies described above; The technical scheme that the present invention adopted is: it includes tabular jig; It is characterized in that: at least three sides of said jig, be provided with locating piece; Having the said locating piece on the side at least at two relative sides is the activity orientation piece, and said jig is connected with bracing frame through hinge, and lifting device is equipped with in said jig bottom.

In the technique scheme, scheme is more specifically: the rear side of the said activity orientation piece on said jig can be provided with clamping device, and the chuck of this clamping device can extend the upper surface place of said workpiece when work;

Further: said clamping device includes first cylinder and second cylinder, and said first cylinder is fixed on the said jig, and the bottom of the said activity orientation piece of the piston rod of said first cylinder connects; The piston rod of said second cylinder and said chuck are hinged;

Further: also be provided with clamping device with the rear side of said activity orientation piece stationary positioned piece in opposite directions, the chuck of this clamping device extends the upper surface place of workpiece when work;

Further: said clamping device includes the cylinder that is fixedly connected with said jig, and the piston rod of said cylinder and said chuck are hinged;

Further: said activity orientation is packaged in gathering sill, and this gathering sill is made up of pressing plate and base plate, and said base plate is fixed on the said jig, and said pressing plate is pressed in the both sides of said base plate;

Further: described hinge is made up of the axle of stationary sleeve and rotation.

Owing to adopted technique scheme, the present invention compared with prior art has following beneficial effect:

1, owing at least three sides of jig, be provided with locating piece, the location becomes convenient, fast, and has guaranteed with batch consistency of product and quality.

2, because the rear side of locating piece on jig is provided with clamping device, use after the fast fixture, it is firm, quick to clamp, and compares with the mode of fixing through welding, has not only saved time, but also laborsaving.

3, because jig is connected with bracing frame through hinge, and lifting device is equipped with in the jig bottom, uses like this after the air-powered lifting device, saved the trouble of using loop wheel machine, it is more convenient that lifting becomes, and both safety was efficient again.

The specific embodiment

Below in conjunction with the accompanying drawing instance the present invention is made further detailed description:

Like Fig. 1 and present embodiment shown in Figure 6; It includes tabular jig 1; On the left and right side of jig and lower side, be equipped with locating piece 8,15 and 4, the locating piece 15 of right edge is the activity orientation piece, and jig 1 is connected with bracing frame 20 through hinge 19; Jig 1 bottom is equipped with and is used the lifting device of cylinder 21 as power, and this lifting device can be make progress jack-up and make jig 1 do rotatablely moving of 90 degree around hinge 19 of jig.

As shown in Figure 2, the rear side of stationary positioned piece 8 is provided with clamping device 2, and cylinder 5 rear portions of this clamping device are fixedly connected with jig 1, and the piston rod of cylinder 5 and chuck 6 are hinged, and chuck 6 extends the upper surface place of workpiece 9 when work.

As shown in Figure 3, the rear side of activity orientation piece 15 is provided with clamping device 3, and first cylinder 11 of this clamping device is fixedly connected with jig 1, and its piston rod is connected with activity orientation piece 15; The piston rod of second cylinder 12 and chuck 14 are hinged, and chuck 14 extends the upper surface place of workpiece 16 when work.

Like Fig. 4, shown in Figure 5, pressing plate 17 is fixedly connected with base 18, and base 18 is fixedly connected with jig 1, and pressing plate 17 forms gathering sill 10 with base 18 combination backs, but activity orientation piece 15 move left and right in gathering sill 10.

During work, at first locate to the back plate, move promotion back plate by activity orientation piece 15 to the jig middle part at last and compress the location by stationary positioned piece 8 and stationary positioned piece 4; When clamping, as shown in Figures 2 and 3, being moved from top to bottom by the chuck 6 and 14 of clamping device 2 and clamping device 3 clamps back plate workpiece; During lifting, cylinder lifting device 21 promotion jigs 1 revolve around hinge 19 and turn 90 degrees, and can reach the purpose of lifting like this.
