Description
Technical field
The present invention relates to a kind of load distributing CNC milling machine main shaft devices, belong to digit ctrol machine tool field.
Background technique
Add on numerically-controlled machine tool in existing machine, it is relatively main that main shaft plays the role of one, and replaces or repair cost
It is very high, virtually increase production cost.
Currently, knife handle is directly embedded on main shaft when using CNC milling machine processing part, power suffered by knife handle when processing
It is all transmitted on main shaft, the size of scrap rate and the difference of feed speed when due to processing, there are also process the material of part not
Equally, cause chip power suffered by its main shaft different, directly affect the service life of main shaft.
Summary of the invention
The object of the present invention is to provide a kind of load distributing CNC milling machine main shaft device, which is simply closed
Reason, the long service life of main shaft can effectively reduce production cost.
The technical solution adopted by the present invention is that: a kind of load distributing main shaft of numerical control machine tool device, which includes device
It is main body, connector, main body blind rivet, positioning deck, first bearing locating clamp plate, angular contact bearing, second bearing locating clamp plate, interior
Set, excessive backing plate, knife handle, knife handle blind rivet, main shaft and ram, described device main body is by four blind rivets and is arranged in the blind rivet
Following connector is mounted on the end of ram and positions the installation site of the fixed described device main body of deck by two, described
Two angular contact bearings are sequentially installed on apparatus main body in centre bore, knife handle is enable freely to revolve inside apparatus main body
Turn, an inner sleeve is provided on the inside of described two angular contact bearings, knife handle passes through knife handle in upper end after the centre bore of inner sleeve
Blind rivet is connect with main shaft, and the upper surface of described inner sleeve is provided with first bearing locating clamp plate, excessive backing plate is provided below, the mistake
It spends backing plate to be connected by bolt and inner sleeve, an annular protrusion, the outside of the annular protrusion, corner connection is had below the inner sleeve
A second bearing locating clamp plate is provided with below contact bearing, the second bearing locating clamp plate passes through bolt and apparatus main body
It is connected.
It advantages of the present invention and has the technical effect that
1, it the present invention provides a kind of design scheme for extending CNC milling machine Main Shaft Service Life, changes original CNC milling machine and adds
When work part, knife handle is directly embedded on main shaft, and power suffered by knife handle is all transmitted on main shaft when processing, makes the use of main shaft
The drawbacks of service life reduction；In normal work, the load generated when by processing disperses away equipment, and the power for carrying main shaft is down to
It is minimum, achieve the effect that extend Main Shaft Service Life.
2, the configuration of the present invention is simple is reasonable, easy to install and use, easy to repair.
3, the present invention can be such that the service life of main shaft doubles above, greatly reduce production cost.
Detailed description of the invention
Fig. 1 is overall structure of the present invention.
Fig. 2 is the A-A sectional view of Fig. 1 of the present invention.
Specific embodiment
As shown in attached drawing 1,2: a kind of load distributing main shaft of numerical control machine tool device, the device include apparatus main body 1, connection
Part 2, main body blind rivet 3, positioning deck 4, first bearing locating clamp plate 5, angular contact bearing 6, second bearing locating clamp plate 7, inner sleeve
8, excessive backing plate 9, knife handle 10, knife handle blind rivet 11, main shaft 12 and ram 13, described device main body 1 pass through four blind rivets 3 and setting
Connector 2 below the blind rivet 3 is mounted on the end of ram 13 and by the fixed described device main body 1 of two positioning decks 4
Installation site, play dispersion load main function；Two angular contacts are sequentially installed in described device main body 1 in centre bore
Bearing 6 enables knife handle 10 to be freely rotatable inside apparatus main body 1, and the inside of described two angular contact bearings 6 is provided with one
A inner sleeve 8, upper end is connect by knife handle blind rivet 11 with main shaft 12 after knife handle 10 passes through the centre bore of inner sleeve 8, the inner sleeve 8 it is upper
Face is provided with first bearing locating clamp plate 5, excessive backing plate 9 is provided below, and the excessive backing plate 9 is solid by bolt and inner sleeve 8
Even, the inner sleeve 8 has an annular protrusion 14 below, is arranged below the outside of the annular protrusion 14, angular contact bearing 6
There is a second bearing locating clamp plate 7, the second bearing locating clamp plate 7 is connected by bolt and apparatus main body 1.
The main shaft 12 is sleeved in the centre bore of ram 13.
Fixing bolt on the first bearing locating clamp plate 5, second bearing locating clamp plate 7 and excessive backing plate 9 is circumferentially
It is uniformly arranged.
The first bearing locating clamp plate 5 and second bearing locating clamp plate 7 limit the freedom degree of about 6 angular contact bearing,
What the excessive backing plate 9 being arranged between described device inner cavity 8 and knife handle 10 can be born knife handle 10 when equipment works normally
Power is transmitted on excessive backing plate 9, and is finally acted on power on ram 13 by all parts on this main shaft device, is avoided
All power is all concentrated on main shaft 12 when previous processing part, the load reduction for bearing main shaft 12, and is able to extend
Its service life.
