Abstract
The present invention provides numerical control bearing shell and mills rubbish slot structure, including bottom plate, shaft and cam；A sliding groove symmetrically is offered on the left of the bottom plate top end face and on the right side of top end face, and the bottom plate left side and right side have been bolted to connection a rectangular slab；Bottom plate bottom face center side position to the front is welded with one piece of fixed rectangular slab；Because of the setting of screw drive structure and threaded drive rod, on the one hand, screw drive structure be can be rotated to adjust the spacing between two fixed arms, at this time because the hand of spiral of threaded rod A and threaded rod B are opposite, therefore when rotation adjusts screw drive structure, two fixed arms can move opposite direction simultaneously, to improve adjustment speed；On the other hand, it can be compared to position to realize to the fixation of different-diameter bearing shell blank with existing apparatus by rotation threaded drive rod to adjust the vertical of placement rack, present apparatus flexibility is higher, and the bearing shell that different-diameter can be adapted to by quickly adjusting is fixed.
Description
Technical field
The invention belongs to bearing shell processing technique fields, and more specifically, in particular to numerical control bearing shell mills rubbish slot structure.
Background technique
Bearing is one of critical component of steam turbine, high to heavy duty under the lubrication and cooling effect of circulating lubricating oil
The turbine rotor of speed operating plays a supportive role, and it is that bearing directly connects with shaft that bearing shell, which is important one of the building block of bearing,
The part of touching, shape are the semi-cylindrical of tiles, and effect is the active force for carrying axle journal and applying, and keep oil-film stabilization, make axis
The peaceful friction loss quietly to work and reduce bearing.The working principle of bearing shell makes bearing shell need to have following characteristic, firstly,
It needs that bearing shell is made using heat-resisting material, so that bearing shell energy high temperature resistant；Secondly, needing bearing shell medial surface being polished to enough light
It slides to reduce the frictional force between bearing shell and shaft to the greatest extent；Finally, needing to guarantee the radian of bearing shell medial surface.
Such as application number: CN201220321655.5, the present invention disclose a kind of automatic processing device of bearing shell medial surface, including
Pedestal, pedestal is flexibly connected motor, and is fixedly connected with limited block, the first pneumatic mechanism, the second pneumatic mechanism, third pneumatic motor
Structure；Motor and third pneumatic mechanism are respectively at limited block opposite side, and the second pneumatic mechanism is in above limited block；First pneumatic motor
Structure is drivingly connected top, and the second pneumatic mechanism is drivingly connected motor, and third pneumatic mechanism is drivingly connected top plate；It is opened up on limited block
Cooperate the first receiving space of bearing shell lateral surface, motor is rotatablely connected cutter.It is an object of the invention to propose in a kind of bearing shell
The automatic processing device of side, implementation through the invention can implement automation processing to the medial surface of bearing shell, meanwhile, it can
Machining accuracy and the processing efficiency of bearing shell medial surface are improved to guarantee product quality.
Based on to application number: the retrieval of CN201220321655.5 patent, although this application can be to the medial surface of bearing shell
Implement automation processing, meanwhile, machining accuracy and the processing efficiency of bearing shell medial surface can be improved to guarantee product quality, still
There are still following deficiencies: one is, flexibility and adjustability are lower, and above-mentioned apparatus, cannot when bearing shell is fixed
The fixation to different size bearing shell is realized in enough adjustment by structure, and overall structure is more inflexible；Furthermore be, cost compared with
Height, in the flexible fixation and replacement to realize blank by hydraulic telescopic rod, cost is higher, can not for above-mentioned application
The quick-replaceable of blank is realized by simple structure.
Then, in view of this, being studied improvement for existing structure and missing, numerical control bearing shell milling refuse chute knot is provided
Structure, to reach more practical purpose.
Summary of the invention
In order to solve the above technical problem, the present invention provides numerical control bearing shells to mill rubbish slot structure, is to solve existing one,
Flexibility and adjustability are lower, and above-mentioned apparatus can not be realized by the adjustment in structure to not when bearing shell is fixed
With the fixation of size bearing shell, overall structure is more inflexible；It furthermore is that cost is higher, above-mentioned application is passing through hydraulically extensible
The flexible fixation and replacement to realize blank of bar, cost is higher, can not realize blank by simple structure
Quick-replaceable the problem of.
The present invention is reached by technological means in detail below:
Numerical control bearing shell mills rubbish slot structure, including bottom plate, sliding groove, rectangular slab, screw drive structure, link block, screw thread

Composition；Fixed arm front end face top position is welded with a briquetting；The base top end face center side position to the front opens up
There is a sliding eye, and slidably connects a rectangular block in the sliding eye；The side position weldering to the front of bottom plate bottom face center
It is connected to one piece of fixed rectangular slab, and is rotatably connected to a shaft on the fixed rectangular slab.
Further, there are two the fixed arm is set altogether, and two fixed arms are slidably connected to respectively in two sliding grooves,
And two fixed arms are threadedly coupled with screw drive structure.
Further, the link block left side and right side are respectively welded a threaded rod A and a threaded rod B,
And the hand of spiral of the threaded rod A and threaded rod B is opposite.
Further, the front end face of each fixed arm is symmetrically welded there are two limited block, and each fixation
The rear end face of arm is also symmetrically welded there are two limited block.
Further, the shaft outer wall front end face is welded with a swing handle, and the shaft rear end face is welded with
One cam, and the cam is in contact with rectangular block bottom face.
Further, the placement rack top end face is v-shaped structure.
Further, the placement rack is slidably connected to the top of rectangular block by four gag lever posts；The screw-driven
Bar is rotationally connected in rectangular block, and the screw-driven rod head end is rotationally connected with placement rack bottom face.
Compared with prior art, the invention has the following beneficial effects:
Because of the setting of screw drive structure and threaded drive rod, on the one hand, can be rotated screw drive structure to adjust two
Spacing between fixed arm, at this time because of the hand of spiral of threaded rod A and threaded rod B on the contrary, therefore adjusting screw-driven knot in rotation
When structure, two fixed arms can move opposite direction simultaneously, to improve adjustment speed；It on the other hand, can be by rotating screw-driven
Bar compares to realize to the fixation of different-diameter bearing shell blank with existing apparatus to adjust the vertical of placement rack to position, this
Device flexibility is higher, and the bearing shell that different-diameter can be adapted to by quickly adjusting is fixed.
Because transferring the setting with cam, when needing to switch bearing shell blank, direct rotating shaft keeps the longest of cam straight
The bottom face of diameter Tuoli rectangular block can carry out replacement blank at this time, can quickly carry out with the prior art present apparatus that compares
The switching more frame of blank is suitable for the batch production of bearing shell.
Because of the setting of limited block, the stability of fixed arm movement can be improved by the limit of limited block, with existing apparatus phase
Adjustment precision can be improved when fixed in comparison, the present apparatus.
