Description
Technical field
The utility model is related to portal frame forcing presses, are used when being assembled especially suitable for the bearing on vibrator.
Background technology
Existing vibrator applying working condition condition very severe, not only ambient humidity is big, dust particles are more, rotating speed is high, strong
Vibratory impulse, i.e. bearing life in vibrator using short, moreover, bearing assembly exerts oneself unevenness, typically staff simultaneously
Firmly bearing is pressed on axis, it is firmly irregular due to being manual operation, cause to exert a force not to bearing inner race during cold setting
, bearing inner race relative axle is caused to generate certain deviation amount, operation process middle (center) bearing inner ring will be worn comparatively fast, to bearing outer ring
Force is uneven, and bearing outer ring also will produce certain deviation amount relative to bearing hole, accelerates to make the outer ring of bearing wear, therefore shadow
Ring the service life of bearing.
Invention content
The task of the utility model is to propose a kind of Automatic manual transmission, firmly uniformly, a kind of bearing gantry with long service life
Frame forcing press.
The task of the utility model is done in such a way that a kind of portal frame forcing press, it is characterised in that：Table base shape
Shape is in square, and the center of the main-vision surface of pedestal is machined with workpiece inlet and outlet, and the shape is in the table core of square
Be symmetrically installed with bottom plate on the table top of position two sides, and be welded with door frame on bottom plate, the top crossbeam of the door frame with it is another
One door frame connection is provided with reinforcing plate around the root of door frame and top, and hydraulic cylinder is assembled by pilot hole and crossbeam, described
There are one cylindrical type pressure heads for connection on hydraulic cylinder piston.The bottom plate is fastened by bolts with table top, and the center of the crossbeam adds
Work has pilot hole.It is in gap shape that workpiece inlet and outlet, which are in the processing of the centre of table base, the length of gap along
Table base extends longitudinally to below hydraulic cylinder, and it is in semicircle that the configured openings end width of the gap, which becomes narrow gradually at closing in,
Shape.
The utility model has the following effects that：The import and export that the bearing that the technical program is related to can be arranged on the table
Into workbench, facilitate the disengaging of workpiece, the service life of bearing and manufacture assembly, using being all closely related, therefore will not in assembly
It tilts, bearing channel will not be caused because stress is damaged, to extend the service life of bearing.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Drawing explanation：1, table base, 2, bottom plate, 3, workpiece inlet and outlet, 4, gap, 5, door frame, 6, reinforcing plate, 7, horizontal
Beam, 8, hydraulic cylinder.
Specific implementation mode
The embodiments of the present invention are described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning
Same or similar element or element with the same or similar functions are indicated to same or similar label eventually.Below by ginseng
The embodiment for examining attached drawing description is exemplary, it is intended to for explaining the utility model, and should not be understood as to the utility model
Limitation.
For specific embodiment as shown in Figure 1, this forcing press includes table base 1,1 shape of the table base is in four
It is rectangular, and the center of the main-vision surface of pedestal is machined with workpiece inlet and outlet 3, the shape is in the table core position two of square
Bottom plate 2 is symmetrically installed on the table top of side, the bottom plate is fastened by bolts with table top, and door frame 5 is welded on bottom plate, institute
The top crossbeam for stating door frame is connect with another door frame, and shape is in portal frame, is provided with and is added around the root of door frame and top
The center of strong plate 6, the crossbeam is machined with pilot hole, and hydraulic cylinder 8 is assembled by pilot hole and crossbeam, and the hydraulic cylinder passes through liquid
Pressure station provides moves under the piston on power drive hydraulic cylinder.There are one cylindrical type pressure heads for connection on the hydraulic cylinder piston.
It is in gap shape that workpiece inlet and outlet, which are in the central part processing of table base, and the length of gap is along workbench
Pedestal extends longitudinally to below hydraulic cylinder, and it is in semicircle shape that the configured openings end width of the gap, which becomes narrow gradually at closing in,.
In summary, the technical program includes table base 1, workpiece inlet and outlet 2, gap 4, hydraulic cylinder 8, is solved existing
It exerts oneself when having the assembly of technology bearing uneven, and the problem of bearing disengaging workbench inconvenience.
When work, axis is entered from workpiece import and is placed on the table top of semicircle shape, is moved down by the piston on hydraulic cylinder
By cylindrical type pressure head by bearing press mounting on axis, then axis is packed into together with bearing in bearing saddle bore, in order to protect when press fitting
It is injury-free to protect bearing, cushion block is lined with above bearing, after having assembled, hydraulic cylinder drives backward stroke of the piston.Bearing assembly is completed, from
And with easy to operate, assembly is quick.
In the utility model unless specifically defined or limited otherwise, term " installation ", " connected ", " connection ", " fixation "
Equal terms shall be understood in a broad sense, for example, it may be fixedly connected, may be a detachable connection or integrally connected, can be two
Connection inside a element.For those skilled in the art, above-mentioned term can be understood in this reality as the case may be
With novel concrete meaning.
