Abstract
The utility model relates to a press-fit tool applicable to parts needing to be pressed, such as oil seals, bearings, gears, synchronizers and the like, and particularly discloses a self-centering press-fit tool. The self-centering press-fit tool comprises a base, a press shaft, a press-fit press head and a screw cap, and is characterized in that a spherical structure is formed at one end of the press-fit press head. The self-centering press-fit tool has the benefits that as the press-fit press head contacts with the press shaft through the spherical structure, the self-centering press-fit tool has a self-centering function, and the center of the press shaft is always perpendicular to the end surface of a pressed part, therefore, the phenomenon that the inclined press head causes the pressed part to incline is eliminated; the tool has simple structure and low manufacturing cost, is simple to operate, and has high press-fit efficiency; and the tool has high universality, is not limited by any conditions, and can perform press-fit through a nylon hammer even in the condition that no hydraulic press exists.
Description
Technical field
The utility model relates to a kind of oil sealing, bearing, gear, synchronized etc. of being applicable to need press-fit the frock that is press-fitted of part, and especially a kind of self-centering is press-fitted frock.
Technical background
Along with the automotive transmission part processing precision is more and more higher, the transmission assembly assembling will become the key of transmission assembly quality, and the assembling of oil sealing, bearing, gear, synchronized etc. will become the key that the assembly quality promotes, but what these press-fited part at present is press-fitted frock self-centering very easily, causes the processing work efficiency low.
Summary of the invention
In order to overcome the existing deficiency that is press-fitted frock that press-fits part, the utility model provides a kind of self centering frock that is press-fitted that has, and the last item center is in all the time perpendicular to by the end face of casting die, tilts to make by the askew phenomenon of casting die pressure thereby solved pressure head.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of self-centering is press-fitted frock, comprises base, last item, is press-fitted pressure head, blind nut, and it is characterized in that: an end that is press-fitted pressure head is the planar structure of hemisphere.
The beneficial effect of this utility model: because of being press-fitted between pressure head and the last item, have the self-centering function, the last item center is in all the time perpendicular to by the end face of casting die, tilt to make by casting die and press askew phenomenon thereby solved pressure head to sphere contacts; The utility model tool structure is simple, and cost of manufacture is low, and is easy and simple to handle, is press-fitted the efficient height; The utility model frock highly versatile is not subjected to condition restriction, even if under no hydraulic press situation, can be press-fitted by the nylon hammer yet.
Below in conjunction with the drawings and specific embodiments the utility model is described further.
Description of drawings
Fig. 1 is a front view structural representation of the present utility model
1. base; 2. last item; 3. be press-fitted pressure head; 4. blind nut.
The specific embodiment
Embodiment one
The utility model is that a kind of JW self-centering is press-fitted frock, comprises base 1, and last item 2 is press-fitted pressure head 3 and blind nut 4.Its feature part is: being press-fitted pressure head 3, contact an end with last item 2 be the planar structure of hemisphere.
Base 1 is encased on the hydraulic press, is put on the base 1 by the matrix of casting die, is press-fitted pressure head 3 and is connected on the last item 2 by blind nut 4, will be placed last item 2 corresponding cylindricals by casting die, by being press-fitted pressure head 3 tops, thereby realizes being press-fitted by casting die.
