Description
Technical field
The utility model relates to a kind of Digit Control Machine Tool parts, especially relates to a kind of to main shaft cutting fluid oil circuit and blow bits mechanism isostructural improvement.
Background technology
At present main shaft cutting fluid oil circuit and blow the bits structure is to offer pipeline in main tapping central authorities, and is provided with an arrival end in the end that cutting fluid imports arrival end with the compressed air sectional, and equally all uses the pipeline derivation of alignment of shafts pull bar.It constitutes as Fig. 1, comprise the main shaft body that is hollow cylindrical, the rear end is provided with oil hydraulic cylinder, is provided with a central through hole in the main shaft body, can enter for pressure-air, and enter for cutting fluid in another through hole, adapter ring is sheathed between main shaft and the pull bar, must utilize nut to adjust the position of this switching ring set, and finishes the path exchange by reducing sleeve, make cutting fluid change into and pass through, and spray by the cutting blade of cutter front end by main shaft body both sides deep hole.But this structure since cutting fluid and compressed air be respectively at the processing cooling with blow alternate conduction when considering to be worth doing, when the cutting fluid switching pressurized air, its pipeline must have residual cutting fluid, follows the pressure-air ejection, around cutting fluid can be splashed, cause surrounding environment and hilt to pollute, and because cutting fluid and compressed air alternate conduction, so it is alternately the time, stand-by period must be arranged, avoiding both to conflict, so the waste on the formation time, working (machining) efficiency influenced.This structure is also because the path of air and cutting fluid is to exchange respectively at the reducing sleeve place, when the tool changing of main shaft palpus, its the potential difference located such as the pull bar that causes be difficult to eliminate, cause the cutting fluid seepage easily in other structures of main shaft, form to pollute, so it must there be very good precision, perhaps needs to adjust nut to change the position of reducing sleeve, very inconvenient, time-consuming.
Summary of the invention
The purpose of this utility model provides a kind of main shaft cutting fluid oil circuit and blows bits mechanism, it mainly is that solution existing in prior technology cutting fluid and compressed air use same passage, during the pressure-air ejection, around cutting fluid can be splashed, cause surrounding environment and hilt pollution problems; The utility model has also solved when main shaft must tool changing, and the potential difference that its institute's pull bar that causes etc. is located is difficult to eliminate, and causes the cutting fluid seepage easily in other structures of main shaft, forms the technical problem of pollution etc.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Main shaft cutting fluid oil circuit of the present utility model and blow bits mechanism, comprise main tapping, main tapping inside is provided with rack sleeve, the rack sleeve lower end is connected with the main shaft body, the upper end is connected with oil hydraulic cylinder, and rack sleeve inside is provided with pull bar, it is characterized in that being provided with in the described oil hydraulic cylinder outside the pipeline connection cylinder of the body of can ventilating, the pipeline other end extends to the outside of pull bar and is connected with runner, and runner extends downward the central authorities of main shaft body; Pull bar inside is provided with the conduit I that can feed cutting fluid, and conduit I extends downward main shaft body lower end.Cutting fluid can be imported in the pull bar by the conduit I at main tapping center, and flows into the hole ejection of main shaft body bottom side, makes cutting fluid can directly be guided to tool edge and cutting place, with the raising cooling effect, and then the precision and the cutter life of increase processing.Pressure-air arrives main shaft body bottom via the runner of other side of main shaft, and is irrelevant mutually with the pipeline of cutting fluid circulation, effectively improves cutting rate.
As preferably, described runner is " U " type, and its lower end is connected with transfer tube, and the transfer tube other end is communicated with conduit II, and conduit II extends to the central authorities of main shaft body.The outer hand hay cutter of pull bar is axially arranged with the U-shaped runner, by transfer tube, conduit II runner is connected to this main shaft body center, makes easy for installationly, and compressed air is sprayed at main shaft body place.
As preferably, have cannelure I outside the described oil hydraulic cylinder, pipeline is communicated with outside the cylinder by cannelure I.Main shaft is when rotating at a high speed, and its pressure-air can be injected by the arbitrary orientation of cannelure, and the influence of not injected the orientation.
As preferably, be connected with link slot between described pipeline and the runner, the link slot diameter is greater than the diameter of pipeline, runner.
As preferably, be connected with cannelure II between the described transfer tube conduit II, cannelure II diameter is greater than the diameter of conduit II.
Link slot and cannelure worker I can make pressure-air allow that slight error exists, the air that link slot and cannelure II leak, because direct and outside air merges, therefore at all can be not influential, also can eliminate the problem of potential difference, thereby reach the shunting of cutting fluid and compressed air, prevent from when jet residual cutting fluid ejection is caused the generation of main tapping surrounding environment pollution problem.Simultaneously, also can promote cutter and cutting portion cooling effect, when link slot and cannelure II can effectively eliminate the cutter tool changing, the potential difference that air channel engages made the rotation of main shaft not be subjected to the interference of pipeline, helps the lifting of spindle speed.
Therefore, the utlity model has cutting fluid and pressure-air circulates in main shaft with shunting mode, when avoiding tool changing jet with residual cutting fluid ejection, can the surrounding environment pollution characteristics; Characteristics such as the utility model also has because each cannelure can effectively eliminate the cutter tool changing time, and potential difference and fit clearance that air channel engages make main axis rotation not be subjected to the interference of pipeline, help the lifting of spindle speed, and be simple and reasonable for structure.
