Description
BUFFER DEVICE FOR PRESS-FITTING
Technical Field of the Invention
The present invention relates to an automatic auxiliary device for
press-fitting, and in particular to a buffer device for press-fitting.
Background of the Invention
In order to improve the production efficiency, a press is often used
together with a rotary plate. By the movement of the rotary plate, a positioning
seat on the rotary plate is moved to a lower side of a press head of the press.
An end cover is placed on the positioning seat, and a bearing is placed on a
bearing retainer of the end cover. The press is activated to enable the press
head to apply a force to the bearing, so that the bearing is press-fitted into the
end cover. During the press-fitting process, there are often certain situations
that may occur to the rotary plate. The rotary plate will be inclined and
deformed after long-time use, so that the height of the positioning seat will be
somewhat decreased and the press-fitting accuracy is thus reduced. Some
rotary plates are fixed on a rotating device, for example, on an index plate. In
this case, due to the inclination of the rotary plate under stress, a linkage
structure between the output end of the rotating device and the rotary plate will
be damaged.
Summary of the Invention
The purpose of the present invention is to provide a buffer device for
press-fitting, which can prevent a rotary plate from inclination under stress
during a press-fitting process as much as possible.
For this purpose, the present invention employs the following technical
solutions. A buffer device for press-fitting is provided, including a rotary plate
and a press both arranged on a working platform, wherein the press includes a
press head; a buffer seat is arranged on the rotary plate; a positioning seat for
positioning a workpiece is arranged on the buffer seat; by the movement of the
rotary plate, the buffer seat is moved to a position directly below the press
head; the buffer seat includes an upper moving block, a fixed block and a
lower moving block; a fixation hole running through the rotary plate from upper
and lower sides is formed on the rotary plate; the fixed block is fixed in the
fixation hole; a number of accommodating grooves running through the fixed
block from upper and lower sides are formed on the fixed block; guide rods are
slidingly fitted in the accommodating grooves; compression springs are
sheathed on the guide rods; upper ends of the guide rods are fixed to the
upper moving block, while lower ends thereof are fixed to the lower moving
block; upper ends of the compression springs come into contact with a lower
end face of the upper moving block; and, the compression springs are
supported on the fixed block.
When a workpiece on the positioning seat is press-fitted by the press, that
is, when the positioning seat is stressed, the positioning seat will transfer the
force to the upper moving block of the buffer seat. At this time, the
compression springs are compressed, and the lower moving block fixed on the
lower side of the upper moving block is moved down and then supported on
the working platform, so that the positioning seat is supported vertically. The
force transferred by the press head will not be transferred to the rotary plate,
so that the rotary plate is prevented from deformation under stress as much as
possible. Thus, the press-fitting accuracy is improved, and the service life of
the rotary plate is prolonged. The positioning seat may be various existing
positioning seats, and the shape of the positioning seat is adapted to the
shape of the workpiece. When it is necessary to press a bearing on an end
cover, a positioning seat capable of positioning the end cover to limit the
movement of the end cover is selected; and, when it is necessary to press a
pin on a planetary carrier, a positioning seat capable of positioning the
planetary carrier to limit the inclination and movement of the planetary carrier
is selected. The positioning seat may be fixed on the upper moving block of the
buffer seat via a fastener, or the positioning seat may be integrally formed on
the upper moving block.
Preferably, each of the accommodating grooves includes an upper
accommodating groove section and a lower accommodating groove section
from the top down, with the inner diameter of the upper accommodating
groove being greater than that of the lower accommodating groove section to
form a step structure; the compression springs are located in the upper
accommodating groove sections; and, upper ends of the compression springs
come into contact with the lower end face of the upper moving block, while
lower ends thereof come into contact with stepped surfaces of the
accommodating grooves. With this arrangement, the device of the present
invention is simpler in structure, and it is convenient for positioning and fixation
of the compression springs. Meanwhile, in the device of the preset invention,
longer compression springs can be used.
Preferably, a bearing platform is arranged on the working platform, the
bearing platform is located directly below the press head, and the buffer seat is
subjected to a downward force so that a lower end face of the lower moving
block comes into contact with an upper end face of the bearing platform.With
this arrangement, the buffer seat can be smaller in size, the lower moving
block does not need to come into direct contact with the working platform, and
the buffer seat is stressed so that the lower moving block is directly supported
on the bearing platform.
Preferably, the lower end face of the upper moving block is recessed
upward to form an upper positioning groove; the upper end face of the lower
moving block is recessed downward to form a lower positioning groove; and,
upper ends of the guide rods are located in the upper positioning groove, while
lower ends thereof are located in the lower positioning groove.With this
arrangement, it is more convenient to fix the upper moving block, the guide
rods and the lower moving block.
Preferably, through holes running through the guide rods from upper and
lower sides are formed on the guide rods, internal thread structures are formed
on the inner walls of the through holes, and sunk troughs in which screws are
fitted are formed on both the upper moving block and the lower moving block.
With this arrangement, it is more convenient to fix the upper moving block, the
guide rods and the lower moving block.
Preferably, an upper positioning ring extending downward is arranged on
an outer edge of the upper moving block, and a lower positioning ring
extending upward is arranged on an outer edge of the lower moving block, with
an inner edge of the upper positioning ring being partially or completely the
same as an outer edge of the upper end of the fixed block in shape, and an
inner edge of the lower positioning ring being partially or completely the same
as an outer edge of the lower end of the fixed block in shape. With this
arrangement, the function of guiding the upper and lower moving blocks during
their upward or downward movement is realized.
Preferably, an outer circumferential edge of an upper portion of the fixed
block is extended toward an outer circumferential side to form an outer bump;
and, when the fixed block is fitted in the fixation hole, the outer bump is
supported on an upper end face of the rotary plate. With this arrangement, it is
convenient for positioning and fixation of the buffer seat and the rotary plate.
Preferably, a positioning bump having an annular cross-section is
extended upward from the upper moving block, and the shape and size of an
inner edge of the positioning bump are the same as those of an outer edge of
the lower end of the positioning seat. With this arrangement, the positioning
seat is positioned, to prevent the positioning seat from moving left and right.
The device of the present invention can prevent a rotary plate from
deformation under stress as much as possible, and thus improve the
press-fitting accuracy and prolong the service life of the rotary plate.
