Further, the threaded hole for installing side shaft holder and intermediate step, side are offered on the positioning plane
Bearing block and intermediate step passes through screw or studs and the positioning plane of upper beam is attached.
Further, the left and right ends side that oil baffle passes through the outer surface and upper beam of screw and two side shaft holders
Face is connected.
The position precision of fine press upper beam structure provided by the utility model, crankshaft hole is high, adopts for support zone
It is laid a good foundation with sliding bearing, it, only need to be by upper beam side after upper beam is separated with Curved shaft support hole (bearing block) therein
It puts, main shaft is stretched out to shorter distance, Feed table processes fixed pan and positioning spigot, and the rigid of main shaft obtains
Guarantee has been arrived, while having improved processing efficiency；The manufacture in Curved shaft support hole (bearing block) can be in the vertical processing of miniature precision
It is manufactured in the heart, since its size is less, machining accuracy is easier to ensure that, but also can take its supported hole accurate rolling
The technique of pressure, can be further improved the accuracy of manufacture；It, can be after the Curved shaft support hole site precision of upper beam is guaranteed
The infinite life of sliding bearing that crankshaft position uses rigidity bigger is as support component, so that the precision of complete machine and service life obtain
Guarantee, the needs of practical application can be met well.

Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, with reference to the accompanying drawing and specifically
Embodiment is described further the utility model.It should be appreciated that specific embodiment described herein is only to explain this reality
With novel, it is not used to limit the utility model.Based on the embodiments of the present invention, those of ordinary skill in the art are not having
Every other embodiment obtained under the premise of creative work is made, is fallen within the protection scope of the utility model.
As Figure 1-Figure 5, a kind of fine press upper beam structure, including the oil baffle 2, two of upper beam 1, two side
Bearing block 3, two intermediate steps 4 and two intermediate top chocks 5；Upper beam 1 is that open " π " shaped cast in middle part makes knot
Structure, place's setting is opened wide in the middle part of upper beam 1, and there are four the positioning plane 1c for being parallel to upper beam upper surface 1e, in positioning plane 1c
Front-rear direction be equipped with positioning spigot 1d, offered on positioning plane 1c for installing side shaft holder 3, intermediate top chock 5
With the threaded hole 1b of intermediate step 4.Processing when only need to guarantee position plane 1c on upper beam plane 1e it is parallel
The width and its position degree relative to 1 center of upper beam (in the front-back direction) of degree and positioning spigot 1d.Two gear oil
Plate 2 is separately mounted at the left and right sides end face 1a for opening wide place in the middle part of upper beam 1.
Two side shaft holders 3 and two intermediate steps 4 are separately mounted on four positioning plane 1c, under two centres
Bearing block 4 is separately mounted on two intermediate positioning plane 1c, and two side shaft holders 3 are separately mounted to two positioning of two sides
On plane 1c.Two intermediate top chocks 5 are separately mounted on two intermediate steps 4.The lower end surface of two side shaft holders 3
3a, two intermediate steps 4 lower end surface 4a fit with corresponding upper beam positioning plane 1c, and pass through positioning spigot 1d
It is positioned.The end face outside of two side shaft holders 3 is aligned with the left and right sides end face 1a of upper beam 1 respectively.
Side shaft holder 3 and intermediate step 4 are carried out by the positioning plane 1c of screw or studs and upper beam 1
Connection, intermediate top chock 5 is assemblied on intermediate step 4 by screw or studs, due to screw or studs
There are gaps between mounting hole, therefore intermediate top chock 5 and intermediate step 4 can carry out appropriate trip in left-right direction
It moves to adapt to possible rigging error.
Oil baffle 2 is connected by screw with two end side surface 1a of the outer surface of two side shaft holders 3 and upper beam 1
It connects, while applying sealant at binding face, to prevent possible oil leak.
Using the technical solution of the utility model, after upper beam 1 is separated with Curved shaft support hole (bearing block) therein, only
Upper beam side need to be put and (for horizontal Machining centers, such as use vertical machining centre, the parallel lathe working face in the face 1c can be put
Set), main shaft is stretched out to shorter distance, Feed table processes fixed pan (fixed bearing block) and positioning spigot,
The rigidity of main shaft is guaranteed, while improving processing efficiency (processing plane is easier than processing hole).Curved shaft support hole (axis
Hold seat) manufacture can be manufactured in miniature precision vertical machining centre, since its size is less, machining accuracy is easier
Guarantee, but also the accurate technique rolled can be taken its supported hole, can be further improved the accuracy of manufacture.The song of upper beam
After axis supported hole position precision is guaranteed, it can be made at crankshaft position using the bigger infinite life of sliding axle of rigidity
For support component, so that the precision of complete machine and service life are guaranteed.
