Abstract
The present invention relates to a kind of novel main shaft housing structures, it includes cylinder body and transmission shaft, described transmission shaft one end is located in cylinder body, they are fixed by positioning pin and lock-screw positioning, the lock-screw is located in the middle part of transmission shaft end surface, the positioning pin is located at cylinder body and transmission shaft connection place, and the transmission shaft is alloy transmission shaft, and the cylinder body is nodular cast iron cylinder body.Structure of the invention setting is reasonable, and easy to process, whole service life is long.
Description
Technical field
The present invention relates to a kind of connection structures, and in particular to a kind of spindle cylinder attachment structure.
Background technology
Currently, main shaft cylinder body mostly uses Nodular cast iron material, when because spheroidal graphite cast-iron is wear-resisting, but because main shaft cylinder body
Transmission shaft is long, and other alloy materials are difficult to operate when processing plunger hole, but there was only surface when ductile cast iron material heat treatment
Very shallow hardened layer, matrix hardness is not high, and bending strength is poor, and driving cog is easy to wear and rupture.
Invention content
Goal of the invention：Purpose of the invention is to overcome the shortcomings in the prior art, and it is reasonable to provide a kind of structure setting,
It is easy to process, the novel main shaft housing structure of whole service life length.
Technical solution：In order to solve the above-mentioned technical problem, a kind of novel main shaft housing structure of the present invention, it includes
Cylinder body and transmission shaft, described transmission shaft one end are located in cylinder body, they are fixed by positioning pin and lock-screw positioning, the lock
Tight screw is located in the middle part of transmission shaft end surface, and the positioning pin is located at cylinder body and transmission shaft connection place, and the transmission shaft passes for alloy
Moving axis, the cylinder body are nodular cast iron cylinder body.
The positioning pin sets 3 altogether, they are uniformly located at cylinder body and transmission shaft connection place.
The transmission shaft is located at cylinder body end Middle face.
Advantageous effect：Compared with prior art, the present invention its remarkable advantage is：Overall structure setting of the present invention is reasonable, it
Easy to process including transmission shaft, cylinder body, positioning pin and lock-screw, transmission shaft is high using hardness, the good alloy material of bending strength
Matter, cylinder body use wear-resisting Nodular cast iron material, effectively improve whole service life, this structure operates steadily using reliably, accords with
Close actual operation requirements.
Description of the drawings
Fig. 1 is the positive structure schematic of the present invention；
Fig. 2 is the side structure schematic diagram of the present invention.
Specific implementation mode
The present invention is further illustrated with reference to the accompanying drawings and examples.
As depicted in figs. 1 and 2, a kind of novel main shaft housing structure of the present invention, it includes cylinder body 1 and transmission shaft 2,
2 one end of the transmission shaft is located in cylinder body 1, they are fixed by positioning pin 3 and the positioning of lock-screw 4, and the lock-screw 4 is set
In the middle part of 2 end face of transmission shaft, the positioning pin 3 is located at 2 junction of cylinder body 1 and transmission shaft, and the transmission shaft 2 is driven for alloy
Axis, the cylinder body 1 are nodular cast iron cylinder body；The positioning pin 3 sets 3 altogether, they are uniformly located at cylinder body 1 and transmission shaft 2 connects
Place；The transmission shaft 2 is located in the middle part of 1 end face of cylinder body.Overall structure setting of the present invention is reasonable, it includes transmission shaft, cylinder body, positioning
Pin and lock-screw, easy to process, transmission shaft is high using hardness, the good alloy material of bending strength, and cylinder body uses wear-resisting ball
Black cast iron quality, effectively improves whole service life, this structure operates steadily using reliably, meets actual operation requirements.
The present invention provides a kind of thinking and methods, and there are many method and the approach for implementing the technical solution, the above institute
State only is the preferred embodiment of the present invention, it is noted that for those skilled in the art, is not being departed from
Under the premise of the principle of the invention, several improvements and modifications can also be made, these improvements and modifications also should be regarded as the guarantor of the present invention
Range is protected, all undefined components in this embodiment can be implemented in the prior art.
