Technical field
This utility model belongs to machine tool accessories field, particularly relates to a kind of interior spherical surface working device.
Background technology
Inner sphere working typically uses pattern to carry out copying on lathe, and this method exists following three points
Not enough: one be the pattern process-cycle length of its turning, difficulty greatly, costly, during use, pattern clamping is also
Relatively difficult；Two is that the sphere processing pattern of different-diameter can not be general, and part processing cost is high；Three is to lean on
Mould adds man-hour and part adds and forms twice mismachining tolerance man-hour, and twice mismachining tolerance accumulation makes some Internal Spherical Surface
The higher part quality of required precision cannot ensure.
Utility model content
In view of this, this utility model provides a kind of simple in construction, highly versatile, and processing cost is low and processes
The interior spherical surface working device that precision is high.
The technical solution of the utility model is, a kind of interior spherical surface working device, including being socketed in boring cutter bar leading portion
Feed push rod, the rear end of boring cutter bar is installed on machine chuck rotatable, and feed push rod is connected with feed support,
Feed push rod can slide axially on boring cutter bar, it is characterised in that: the back segment of described boring cutter bar is hinged with a U
Shape fork, the opening line of U-shaped fork upper end is vertical with the axis of boring cutter bar, and the lower end of U-shaped fork is provided with cutter
The boring cutter that sword is downward；The described feed push rod end being socketed on boring cutter bar is provided with sliding sleeve, this sliding sleeve and feed
End face thrust bearing it is provided with between the end of push rod；By one between lower end and the sliding sleeve of described U-shaped fork
Connecting rod connects.
Further, described boring cutter is close to be connected on the lower end of U-shaped fork by bolt lock.
Further, the rear end of described boring cutter bar is provided with one for the clamping boss being connected with machine chuck.
The beneficial effects of the utility model are, by the movement on boring cutter bar of the feed push rod and boring cutter bar
The rotation of self, under the drive of U-shaped fork and connecting rod, boring cutter can be simple and high-precision complete Internal Spherical Surface
Cutting feed campaign.For the processing of different Internal Spherical Surface, only U-shaped fork, connecting rod and boring cutter need to be carried out
Adjust.This utility model new construction is simple, and highly versatile, convenient mounting and clamping use this device to process
Element precision is high, low cost, is the ideal device of machining high-precision Internal Spherical Surface.

Detailed description of the invention
In order to make those skilled in the art be more fully understood that the technical solution of the utility model, below in conjunction with attached
The utility model is described in further detail with specific embodiment for figure.
As shown in figures 1 and 3, this utility model one interior spherical surface working device includes feed push rod 1 and boring
Knife bar 2.Wherein, feed push rod 1 is socketed in the leading portion of boring cutter bar 2, and the rear end of boring cutter bar 2 is installed in lathe
On chuck, under the drive of machine chuck, boring cutter bar 2 can rotate around the axis of self.In order to make boring
Knife bar 2 can consolidate and be installed on machine chuck, is provided with a clamping boss 201 in the rear end of boring cutter bar 2.
Feed push rod 1 is then connected with feed support, and under the drive of feed support, feed push rod 1 can be in boring cutter bar 2 upper shaft
To sliding and only axially moving.
As depicted in figs. 1 and 2, the back segment at boring cutter bar 2 is hinged with a U-shaped fork 6, U-shaped fork 6
The opening line of upper end is vertical with the axis of boring cutter bar 2, and the lower end of U-shaped fork 6 is provided with the boring cutter that blade is downward
7.Only axially move on boring cutter bar 2 to realize feed push rod 1, be socketed in the feed on boring cutter bar 2
Push rod 1 end is provided with sliding sleeve 4, is provided with end face thrust bearing 3 between this sliding sleeve 4 and end of feed push rod 1.
It is connected by a connecting rod 5 between the lower end of U-shaped fork 6 with sliding sleeve 4.
Operationally, the clamping boss 201 of boring cutter bar 2 is stuck on machine chuck, at chuck this utility model
Drive under only rotate, do not axially move.Boring cutter bar 2 drives U-shaped fork 6 and boring cutter 7 to revolve
Turn, complete principal cutting movement.Meanwhile, U-shaped fork 6 drivening rod 5 and sliding sleeve 4 rotate in the lump.Due to cunning
Being provided with end face thrust bearing 3 between set 4 and feed push rod 1, the feed push rod 1 being located on boring cutter bar 2 will not
Rotate, but feed push rod 1 can move forward and backward along boring cutter bar 2 under the drive of feed support.When feed push rod 1
When pushing ahead, sliding sleeve 4 also will move forward on boring cutter bar 2, and make U-shaped fork 6 by connecting rod 5
Swing around its pin joint, and make the boring cutter 7 being contained on U-shaped fork 6 complete cutting feed campaign.Boring cutter 7
The feeding track of point of a knife is that radius is equal to the point of a knife circular arc to the spacing of fork pin joint, namely to process
The inner sphere radius of workpiece 8.
When the centre of sphere is at the center of workpiece 8, as shown in Figure 4, the circular diameter on the ball cross section at workpiece 8 two ends
Equal；Otherwise, unequal, as shown in Figure 5.Before work: one, according to axis of small circle D on cross section and leave
Reasonably allowance machined bottom, then according to inner sphere radius and leave rational allowance roughing ball
Face.Two, adjust the installation site of boring cutter 7 so that it is the distance between point of a knife cutter to U-shaped fork 6 pin joint
Equal to inner sphere radius.Three, during clamping, the pin joint of U-shaped fork 6 with boring cutter bar 2 is placed in Internal Spherical Surface
The centre of sphere after fix workpiece 8.
