The structure has the beneficial effects that the high-speed machining for precision parts and special material parts can be completed; automatic jet flow, cooling and punching for cutting fluid under the machining state can be realized; therefore, the processing precision and efficiency as well as the knife durability can be improved.

Description

Main shaft side high pressure water flowing out structure in the machining center

Technical field

The utility model relates to a kind of machining center, relates in particular to the main shaft in a kind of machining center.

Background technology

Development along with automobile, mould, Aeronautics and Astronautics technology, the processing of special substance parts such as some precision components, best bright finish Surface Machining, dark aperture processing, aluminium alloy, titanium alloy, stainless steel, except that process equipment, cutter and processing technology being had strict requirement, the rotating speed and the function of high-speed main spindle are also had higher requirement.At present, certain customers adopt the high speed and precision main shaft that has the center spraying function of 10000rpm～12000rpm, though solved some difficult problems in the high-speed cutting processing,, the cost of this structure is higher relatively, grasps and installs and adjust certain technology that needs.Therefore, seek simple and fast, with low cost, the processing method of economic actual effect and approach are to enjoy popular confidence.

As seen from Figure 1: this structure is made up of main shaft casing 1, accurate main shaft 2, standard handle of a knife 30 and standard cutter 40.During machine tooling, standard handle of a knife and cutter connect with accurate main shaft and rotate at a high speed with main shaft, finish the processing to workpiece under programme-control.Blade certainly leads to high temperature and cutting resistance when cutting workpiece, to realize cooling, lubricated this moment, reach smooth and easy chip removal, have only by the outer auxiliary equipment of machining area, could be with the cooling medium jet flow in cutter and processing district, and utilize the cutter helical flute to bring inside, processing district into, to improve working (machining) efficiency and to reduce tool wear.

Above-mentioned structure does not possess jet flow refrigerating function from inside to outside, be difficult for chip removal and cooling, continuous increase chip removal along with working depth is difficult more simultaneously, especially the blade front end can not get good cooling and lubricated, not only tool wear can not be effectively reduced, machining accuracy and working (machining) efficiency can be influenced on the contrary.

Summary of the invention

The utility model technical issues that need to address have provided a kind of machining center main shaft side high pressure water flowing out structure, are intended to solve the above problems.

In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:

The utility model comprises: the interior accurate main shaft of main shaft casing that is installed on lathe; Also comprise: the oil circuit handle of a knife inserts the taper hole of accurate main shaft, and the cutter of band centre bore is placed under the oil circuit handle of a knife; Scotch is installed on the ring flange of lower end, main shaft right side; On scotch, settle and connect pipe joint and the pipe fitting that an end connects the oil circuit handle of a knife; The other end of pipe joint and pipe fitting is connected circulated filter system, control magnetic valve and booster pump successively and links to each other with the liquid case.

Compared with prior art, the beneficial effects of the utility model are: can finish the processing of precision component, special substance part under high speed, realize automatic jet flow, the cooling of machining state cutting fluid and dash bits, improved machining accuracy, efficient and the tool life of part.

Description of drawings

Fig. 2 is the utility model structural representation.

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:

As seen from Figure 2: the utility model comprises: be installed on the accurate main shaft 2 in the main shaft casing 1 of lathe; Also comprise: oil circuit handle of a knife 3 inserts the taper hole of accurate main shaft 2, and the cutter 4 of band centre bore is placed in the oil circuit handle of a knife 3 times; Scotch 6 is installed on the ring flange of lower end, main shaft right side; On scotch 6, settle and connect pipe joint 7 and the pipe fitting 8 that an end connects oil circuit handle of a knife 3; The other end of pipe joint 7 and pipe fitting 8 is connected circulated filter system 12, control magnetic valve 11 and booster pump 10 successively and links to each other with liquid case 9;

On described scotch 6, also comprise a sealing ring 5 that seals with the scotch delivery port.

The utility model is installed on accurate main shaft 2 in the main shaft casing 1 of lathe, and scotch 6 is installed on the ring flange of lower end, main shaft right side, and guarantees the centre distance with main shaft; When dedicated tool 4 and oil circuit handle of a knife 3 integral body were inserted spindle taper hole, locating shaft combined with scotch delivery port sealing ring 5, and locating shaft is limited the position by scotch breach boss in radial direction simultaneously, made oil circuit handle of a knife outer body and main axis rotation keep relative static; Pipe joint 7, pipe fitting 8, liquid case 9, booster pump 10 and control magnetic valve 11, circulated filter system 12 constitute the feed flow loop with scotch.

Scotch of the present utility model is installed in the main shaft bottom righthand side, and be connected with the liquid case by the pipeline pipe fitting, machining medium: water (or oil) is transported to scotch through pump, filter and pipeline, inject the oil circuit handle of a knife through scotch again, enter the machining district by the center cutter hole at last and cool off and dash bits.

The utility model unlike the prior art be exactly to have increased the hot side effluent functions, be used oil circuit handle of a knife and dedicated tool, can effectively control processing temperature rise and tool wear, strengthen the chip removal ability, help improving working (machining) efficiency and guarantee machining accuracy.

The utility model substitutes common handle of a knife with the oil circuit handle of a knife, and the scotch of installing with the main shaft side end face cooperates butt joint, and dedicated tool (band centre bore) rotates at a high speed and the maintenance of oil circuit handle of a knife is not rotated; High-pressure hydraulic pump is squeezed into scotch with cooling medium (water or oil), enters dedicated tool by the oil circuit handle of a knife again and is discharged into the processing district, helps high-speed cutting processing and cutter protection.

Operation principle of the present utility model: during machine tooling, control instruction control booster pump and magnetic valve operation, and the cutting fluid after will filtering is squeezed into scotch, enter the cutting edge of cutter through the oil circuit handle of a knife, high speed rotation along with cutter, the just full machining area of cutting fluid has been realized the automatic jet flow, cooling, lubricated and dash the bits function of machining state cutting fluid.
