The utility model discloses can be used to the numerical control merry go round machine, solve the cutting fluid and followed the technical problem of leaking in the middle of the main shaft easily, improve the work efficiency and the security of lathe.
Description
Technical Field
The utility model relates to a technical field is made to the lathe main shaft, concretely relates to prevent tight system that expands of chuck seepage.
Background
As is well known, the cutting fluid is an industrial fluid used in metal cutting and grinding processes for cooling and lubricating a tool and a workpiece, and a cutting fluid spraying device is usually arranged on a spindle to spray cold cutting fluid for the purpose of cooling the tool and cleaning the workpiece during cutting.
When the numerical control vertical lathe is used, if a waterproof mechanism of a main shaft is not made, cutting fluid can leak from the middle of the main shaft, a chuck on the main shaft and a chuck pull rod are connected through threads and can be well sealed, but the chuck pull rod is connected with a pull rod below the chuck pull rod through screws, and a gap is formed between the end surface of the chuck pull rod and the end surface of the chuck pull rod according to structural requirements, so that the cutting fluid leaks from the middle of the chuck to the middle of the main shaft through the gap, the work of the main shaft is influenced, the work efficiency of a lathe is reduced, and the risk of the work of the lathe is increased.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a prevent tight system that expands of chuck seepage through set up the tight inner ring that expands in the chuck pull rod and expand tight clamp plate etc. has solved the technical problem that the cutting fluid leaks from the intermediate position of chuck easily. The utility model provides a plurality of technical effects that preferred technical scheme among a great deal of technical scheme can produce see the explanation below in detail.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides an expansion system for preventing chuck leakage, which comprises a chuck pull rod, a chuck connecting disc, an expansion inner ring and an expansion pressing plate; wherein:
alternatively or preferably, the expansion inner ring is mounted inside the chuck pull rod;
optionally or preferably, the expansion pressure plate is mounted above the expansion inner ring;
optionally or preferably, an expansion outer ring is arranged between the expansion pressing plate and the expansion inner ring;
optionally or preferably, a groove is formed in the expansion inner ring, and an O-ring is installed in the groove.
Alternatively or preferably, the diameter of the O-ring is greater than the depth of the groove.
Optionally or preferably, the expansion inner ring and the expansion pressure plate are connected through screws.
Optionally or preferably, the central positions of the expansion inner ring and the expansion pressing plate are further provided with loosening screw holes for loosening the expansion inner ring and the expansion pressing plate.
Based on the technical scheme, the following technical effects can be generated:
the embodiment of the utility model provides a pair of prevent tight system that expands of chuck seepage is applicable to the condition that main shaft cutting fluid can follow the middle leakage of main shaft in the lathe course of working. The utility model relates to a prevent tight system that expands of chuck seepage reaches interference fit between tight system that expands and the chuck pull rod through set up the tight inner ring that expands and expand clamp plate etc. in the chuck pull rod, expands promptly tight inner ring and the tight back that expands, plays sealed effect, and O type circle also cooperates in addition and plays sealed effect, and double sealing blocks the leakage way of cutting fluid to the technical problem of leakage in the middle of the main shaft has been solved easily to the cutting fluid.
