Abstract
The utility model discloses a multi-head floating press head device which is characterized by comprising a cylinder body, wherein the cylinder body is internally provided with a plurality of oil chambers horizontally; a pressing rod vertically extending on the cylinder body is arranged in each oil chamber respectively; the center of the cylinder body is provided with a chamber; and the chamber is communicated with the plurality of oil chambers by pipelines. The multi-head floating press head device is applicable to the occasions with higher precision such as synchronous press-in of multiple workpieces, can be especially applied to mechanical machining, automobile part assembly and mechanical equipment assembly, and can carry out multi-head synchronous press-mounting on the workpiece such as a pin shaft.
Description
Technical field:
The utility model relates to a kind of multi-head floating pressure head device.
Background technology:
In the mechanical press mounting industry, sometimes need a plurality of bearing pin class parts are pressed in the workpiece, at present in most of mechanical press mounting mechanism, the way that adopts is that a plurality of column pressure heads vertically are welded on the whole plate, when press-fiting workpiece, a plurality of pressure heads difference correspondences on a plurality of bearing pin class parts, are exerted pressure to entire plate again, transfer the pressure on the bearing pin class part by pressure head.The way that also has is that a plurality of bearing pin class parts are press-fited separately singly.The shortcoming that the above multiplex's part press-fits is: pressure head length can not guarantee consistent cause pressure assembling force inhomogeneous, press-fit step many, press-fit overlong time, press-fit deficiencies such as not in place, frock complexity.
Summary of the invention:
For overcoming the defective of prior art, the purpose of this utility model is to provide a kind of multi-head floating pressure head device.Be applicable to the higher occasions of precision such as multiplex's part is pressed into synchronously, but concrete application machine processing automobile parts assemble, the plant equipment assembling, can carry out the device that bull press-fits synchronously to bearing pin class workpiece.
The utility model technical solution problem adopts following technical scheme:
Multi-head floating pressure head device, it is characterized in that being provided with a cylinder body, a plurality of oil pockets of horizontal distribution in described cylinder body, correspondence is provided with vertically extending depression bar on cylinder body in each oil pocket, and one cavity being set in the central authorities of cylinder body, described cavity is communicated with described a plurality of oil pockets by pipeline.
Described cylinder body is disc, and described cavity is arranged at the central authorities of cylinder body, and it is that described a plurality of oil pockets are communicated with described cavity by pipeline separately on the circumference of circle in the center of circle that described a plurality of oil pockets are distributed in the cavity.
The end of each depression bar all is provided with pressure head removably.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
The equal correspondence in top that the utility model is used to press-fit the depression bar of bearing pin class part is provided with oil pocket, each oil pocket all is communicated with the cavity of cylinder body central authorities, also promptly realized the intercommunication of butter in each oil pocket, and realized depression bar float and a plurality of depression bars between interlock, can realize that bull press-fits synchronously, depression bar quantity can be according to the quantity design that press-fits workpiece; Processing request to depression bar, pressure head is not high, does not need highly in full accord; Features simple structure, applied widely.
The utility model can disposablely be pressed into a plurality of workpiece, efficient height; The pressure of a plurality of depression bars is even, guarantees that each workpiece is pressed into place.
Description of drawings:
Fig. 1 is a structural representation of the present utility model; Fig. 2 is that the A of Fig. 1 is to cutaway view.
Number in the figure: 1 cylinder body, 2 connecting plates, 3 upper cylinder covers, 4 hexagonal socket head plugs, 5 depression bars, 6 times cylinder caps, 7 lower flanges, 8 pressure heads, 9 oil pockets, 10 cavitys.
Below pass through the specific embodiment, and the utility model is described in further detail in conjunction with the accompanying drawings.
The specific embodiment, non-limiting examples is as described below:
Embodiment: in conjunction with Fig. 1,2, the multi-head floating pressure head device of present embodiment, be applicable to the higher occasions of precision such as multiplex's part (bearing pin class part) is pressed into synchronously, but concrete application machine processing automobile parts assembling, plant equipment assembling, this device can realize that multiplex's part (identical) press-fits synchronously, and guaranteeing that workpiece all is pressed into place, pressure assembling force is consistent simultaneously, avoids defective work piece.Concrete scheme is that a discoidal cylinder body 1 is set, the a plurality of oil pockets 9 of horizontal distribution are equipped with butter in the oil pocket in cylinder body, and correspondence is provided with vertically extending depression bar 5 on cylinder body in each oil pocket, and a cavity 10 being set in the central authorities of cylinder body 1, described cavity is communicated with described a plurality of oil pockets by pipeline.
In conjunction with Fig. 2, cavity 10 is arranged at the central authorities of cylinder body, and it is that described a plurality of oil pockets are communicated with described cavity by pipeline separately on the circumference of circle in the center of circle that described a plurality of oil pockets are distributed in the cavity.
In conjunction with Fig. 1, each oil pocket 9 is provided with upper cylinder cover 3 and following 6 pairs of oil pockets of cylinder cap seal, the below of following cylinder cap is pushed down to be connected on the cylinder body 1 lower flange 7, and the top of upper cylinder cover 3 is pushed down with the connecting plate 2 that is connected on the cylinder body, and drive source is connected the top of connecting plate 2 by T type bolt.The sidepiece of oil pocket can replenish butter with hexagonal socket head plug 4 sealings with the hexagonal socket head plug taking-up in oil pocket, upper cylinder cover must be taken out as changing butter again.
During work, pressure head 8 correspondences of depression bar 5 ends are placed a plurality of bearing pin class parts top, by single drive source cylinder body 1 is exerted pressure, promote depression bar 5 and pass through cylinder cap 6 guiding movements down, when pressure head 8 touches workpiece, pressure is passed to the butter in the cylinder interior oil pocket 9, butter can be according to the size and the transmission sequencing of each ram pressures, (by the cavity 10 of pipeline and cylinder body central authorities) moves complementary in oil pocket and between each oil pocket, give the certain amount of floating of each pressure head, thereby guarantee freely the changing of all even pressure head high and low position of ram pressures.
