Abstract
The utility model discloses a top pressing head device, which comprises a top pressing body, a thimble, a connecting body, a spring, a hemispheroid and an outer housing, wherein the thimble is arranged in a top pressing body chamber; the top part of the thimble passes through the connecting body and the hemispheroid and extends out; the spring is arranged behind the thimble; the connecting body is arranged at the head end of the top pressing body; the hemispheroid is arranged on a concave surface of the connecting body; one end of the outer housing presses the edge of the hemispheroid and the other end of the outer housing is connected with the connecting body; and the top pressing head device comprises the top pressing body, a mandril and the hemispheroid. The top pressing head device is characterized in that the hemispheroid is arranged in the concave surface at one end of the top pressing body; the mandril is arranged in the hemispheroid and the top pressing chamber body; and one end of the mandril, which is provided with a ball head, faces to the hemispheroid. The utility model can be self-adaptively tightly attached to the end surface of an axle and reduces the damage of the thimble, the top pressing head and the end surface of the axle in the disassembly process as much as possible. The hemispheroid can be replaced even if being damaged and the loss is less. The utility model meets the requirements of a high-precision wheel of a high-speed train on the press installation and the withdrawing.
Description
Technical field
The utility model relates to parts of train wheelset fitting, dismounting machine, and specifically preceding with being installed in the oil cylinder piston bar a kind of roof pressure head unit is relevant.
Background technology
The push pin device that is generally used for machining generally all is to be contained on the tailstock of lathe, and it mainly rises and supports and positioning action, in the process, also will bear and axial vertical power certainly, because use is frequent, the thimble conehead partly is easy to wearing and tearing.But when push pin device be installed in press-fit or the dismounting machine oil cylinder before, be used for wheelset fitting or move back when unloading, it not only will play location and supporting role, also to directly bear press-fit or move back unload wheel to the time huge axial thrust, the time one is long, wearing and tearing partly not only can appear in the thimble conehead, mushrooming deformation also may occur and damage, on the other hand, may cause the damage of wheel axle end surface in addition, this wheel shaft for required precision very high wheel shaft, especially EMUs is unallowed.In the practice, also having a kind of situation, is exactly that axletree end face and roof pressure end surface might be fitted and be not fine, can influence the stressed and end face of axle like this, therefore is necessary the roof pressure head is improved.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of roof pressure head unit, and it is reasonable in design, and adaptivity is strong, can avoid the damage of thimble, pressure head end face and wheel axle end surface effectively.
In order to achieve the above object, the technical solution of the utility model is: a kind of roof pressure head unit, comprise roof pressure body, thimble, connector, spring, hemisphere, outer cover, it is characterized in that: described thimble is contained in the roof pressure body cavity, and its top part is passed connector and hemisphere and stretched out, and spring is equipped with in the back of thimble, the head end of roof pressure body is equipped with connector, on the concave surface of connector hemisphere is housed, edge of pushing down hemisphere of outer cover, another square toes connect with connector.
Another scheme is: a kind of roof pressure head unit, comprise roof pressure body, core bar, hemisphere, and it is characterized in that: described hemisphere places in the concave surface of one of roof pressure body, and core bar is contained in hemisphere and the roof pressure body cavity, and core bar has an end of bulb towards hemisphere.
The beneficial effects of the utility model are that the energy self adaptation fit tightly the axletree end face, reduces thimble, roof pressure head, axletree end face hurt in assembling and dissembling process as far as possible, even hemisphere damages, might as well change, and lose less.Satisfy bullet train high accuracy wheelset fitting and moved back the needs that unload.
Description of drawings
Fig. 1 is the utility model scheme one structural representation.
Fig. 1 is the utility model scheme two structural representations.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified.As shown in Figure 1, a kind of roof pressure head unit, comprise roof pressure body 1, thimble 2, connector 3, spring 4, hemisphere 5, outer cover 6, described thimble is contained in the roof pressure body cavity, and its top part is passed connector and hemisphere and stretched out, and spring is equipped with in the back of thimble, the head end of roof pressure body is equipped with connector, on the concave surface of connector hemisphere is housed, edge of pushing down hemisphere of outer cover, another square toes connect with connector.
Because between thimble body and the cavity certain clearance is arranged, therefore, in the process of roof pressure, hemisphere can be done certain deflection, makes it to fit with the axletree end face.Outer cover is pushed down hemisphere and is made it unlikely and deviate from.
As shown in Figure 2, a kind of roof pressure head unit comprises roof pressure body 1, core bar 2, hemisphere 3, and described hemisphere places in the concave surface of one of roof pressure body, and core bar is contained in hemisphere and the roof pressure body cavity, and core bar has an end of bulb towards hemisphere.
The utility model scheme one mainly is to be used for double end oil cylinder wheelset fitting dismounting machine, and scheme two mainly is to be used for the single head oil cylinder to press-fit dismounting machine.
