If the tolerance between the external diameter of axle and the internal diameter of the through hole is too big, when the spindle and the axle rotate simultaneously, a tail swinging situation will happen to the rotary joint, which can make the wear resistant tablet crashed to leak cutting fluid. The utility model comprises a frame which is provided with the rotary joint. A base is fixedly connected with the frame and the rotary joint is fixedly connected with the base. The knife hitting mechanism at the lower end of the rotary joint includes a bolted joint which is sleeved externally with a driven rotary joint. The driven rotary joint is arranged internally with a coupled axle. A sleeve is arranged under the bolted joint. The coupled axle extends downward to be fixedly connected with a transmission adapter base. The transmission adapter base is communicated internally with a mandrel and is sleeved externally with the spindle. A pressure cylinder axle which is connected with the knife heating sleeve is arranged at the upper end of the frame.
Description
Technical field
The utility model relates to a kind of Digit Control Machine Tool parts, especially relates to a kind of to using the improvement of spraying mechanism in the main shaft cutting fluid in comprehensive machine.
Background technology
The mechanism that forges a knife of comprehensive process center machine is the principal organ of this kind toolroom machine at present, its structure as shown in Figure 1, the main shaft of mechanism of forging a knife is fixed with the gear that is driven by motor outward, be equiped with spring in the perforation of this main shaft, the nearly top of main shaft is slidingly equipped with central siphon, central siphon inner bottom and axle are spirally connected, put for the bolted joint spiral shell of swivel joint on the central siphon top, swivel joint is set in the interior perforation of cylinder pressure, the urceolus of swivel joint is fixed on the toolroom machine, cylinder pressure also is fixed on the toolroom machine, and the drivable shaft pipe produces displacement; Set of tools in order to cutting workpiece is loaded in the chuck of axle bottom, and in addition, the urceolus of swivel joint is provided with the cutting fluid inlet, after injecting cutting fluid, can flow into the axle center, it is full in cutter and workpiece, to reach the effect of cooling with automatic spray to flow to chuck again.Work as motor running, when the gear drive main shaft rotates, driving the central siphon that is positioned at the top by spring tension rotates, adding axle, bolted joint also can rotate, and then chuck is rotated, make cutter cut to workpiece, when bolted joint rotates, the urceolus of swivel joint is to be the moving state that maintains static, and when desiring to change the outfit cutter, pass toward the chuck direction together with axle, and then striking chuck in axle bottom is down passed by the cylinder pressure drive shaft tube, the jaw of clipping chuck is unclamped and cutter is taken off, and the new cutter that can change the outfit.But this mechanism that forges a knife is because central siphon is to be slidingly installed in the perforation of main shaft, and this central siphon is subjected to the driving of cylinder pressure and produces displacement, and the external diameter of central siphon cooperates needs quite precision and difficult manufacturing with the aperture of main shaft perforation.When if the id tolerance of central siphon external diameter and perforation is too big, when main shaft and central siphon rotate simultaneously, swivel joint will have the whipping situation to produce because of the excesssive gap of main shaft and central siphon, make the wear plate squeeze crack of swivel joint inside and make the cutting fluid seepage, swivel joint is promptly accused damage and need be renewed.
Summary of the invention
The purpose of this utility model provides spraying mechanism in a kind of main shaft cutting fluid, it mainly is to solve existing in prior technology tool-broaching mechanism central siphon to be slidingly installed in the perforation of main shaft, and the external diameter of central siphon cooperates needs quite precision and the problem of difficult manufacturing with the aperture of main shaft perforation; The utility model has also solved the id tolerance of central siphon external diameter and perforation when too big, when main shaft and central siphon rotate simultaneously, swivel joint will have the whipping situation to produce because of the excesssive gap of main shaft and central siphon, make the wear plate squeeze crack of swivel joint inside and make the cutting fluid seepage, swivel joint is promptly accused the technical problem of damaging and need renewing etc.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Spraying mechanism in the main shaft cutting fluid of the present utility model comprises framework, is provided with the swivel joint that has the cutting fluid inlet in the framework, and the swivel joint lower end is provided with the mechanism that forges a knife, and its feature is connected with pedestal in described framework, and swivel joint is fixed on the pedestal; The described mechanism that forges a knife comprises bolted joint, bolted joint is socketed with driven adapter outward, be provided with couple axle in the driven adapter, the bolted joint below is provided with sleeve, the couple axle upper end is actively socketed on sleeve inner, couple axle extension downwards is connected with the transmission adapter, and transmission adapter inside has connected axle, and its outer cover is connected to main shaft; Described framework upper end is provided with pressure cylinder shaft, and it is connected with the cover of forging a knife that can drive the axially-movable of transmission adapter.Hollow is enclosed in axle inside, and it is sheathed in the main shaft, and the bottom of main shaft is assembled with the cutter of cutting usefulness, and the top of framework is assembled with cylinder pressure, and cylinder pressure drives pressure cylinder shaft can control the action that axle decline work is forged a knife.The outer surface of swivel joint is provided with the cutting fluid inlet, injects for cutting fluid, and mechanism, the axle center of forging a knife of flowing through flow to the cutter that is assembled in the main shaft bottom again, needed cooling effect so that Tool in Cutting to be provided.Between the inwall of transmission adapter and main shaft for being slidingly matched, to keep the running accuracy of transmission adapter.Couple axle is the circular thin body of rod of hollow, for cutting fluid heart circulation therein.The body of swivel joint is owing to be to be fixed on the pedestal, so swivel joint will can be along with main shaft rotates, and then avoid producing whipping and be offset, even the center of main shaft and swivel joint is slightly during decentraction, because the couple axle that connects between transmission adapter and the driven adapter is thin round bar, avoid swivel joint to produce vibration so can absorb the beat amount of decentraction.
As preferably, be provided with the fit end of outer-hexagonal on the described couple axle, its external diameter is less than this body diameter of couple axle; Be provided with the sleeve joint hole that is complementary with the fit end in the sleeve.The outer-hexagonal shape fit end on couple axle top and the interior hexagonal sleeve joint hole of driven adapter inner sleeve are fastened, and can drive driven adapter and rotate.
As preferably, be provided with step in the described transmission adapter, the couple axle lower end snail is connected on the step.
As preferably, be connected with guide bar on the described framework, forging a knife to put has the guide hole that penetrates guide bar, and making forges a knife overlaps and can move up and down along guide bar.
Therefore, the utlity model has swivel joint displacement when avoiding forging a knife, and swivel joint whipping beat vibration along with spindle operation, the characteristics that prolong the swivel joint life-span; It is tiny pole that the utility model also has the couple axle that extends on transmission adapter top, when between swivel joint and the main shaft if when having micro-decentraction situation to exist, can absorb the beat amount of decentraction and avoid generation of vibration, characteristics such as simple and reasonable for structure.
