Abstract
The utility model provides a machine tool which comprises the following components: a unclamping cylinder, a unclamping sleeve, a main shaft and a cutter; wherein, the center of the main shaft has a hollow structure. Cooling liquid cools the cutter through the center of the main shaft. The cooling liquid is sprayed on the cutter through the center of the main shaft. The machine tool has the following advantages: high cooling effect, capability of preventing thermal deformation of the cutter and the workpiece, capability of keeping stable precision of the cutter, greatly improved cutting rate and prolonged service life, and higher suitability for the components with deep machined holes.
Description
Technical field
The utility model relates to a kind of lathe, and is special, relates to a kind of lathe with good cooling effect.
Background technology
In field of machining, lathe is to carry out the cut necessary tool.
Be illustrated in figure 1 as the machine tool structure sketch map of prior art, 11 is main tapping, and 12 is Spindle Motor, and 13 is main shaft, and cutter is set on main shaft, is used for processing work.
Shown in Figure 2 is the side view of the lathe of prior art, as schemes saidly, and the also extra cooling tube that is provided with is used for cutter is cooled off outside main shaft.Such type of cooling cooling effect is not very desirable.
The utility model content
To the above-mentioned deficiency of prior art, the utility model provides a kind of lathe, and it comprises: knife striking cylinder, and the sleeve pipe of forging a knife, main shaft, cutter, wherein, the center of main shaft is a hollow structure, cooling fluid is cooled off cutter via the center of main shaft.Cooling fluid is ejected on the cutter through the alignment of shafts, and cooling effect is good, prevents that cutter and workpiece from producing thermal deformation, and can keep the stable accuracy of cutter, significantly promotes stock removal rate and prolongs cutter life, and is more suitable at the part to deep hole machining.
Preferably, the center of cutter also is a hollow structure, and cooling fluid is cooled off cutter via the center of cutter.
Preferably, the sleeve pipe of forging a knife connects knife striking cylinder and main shaft, and knife striking cylinder is forged a knife to alignment of shafts outer ring.
Preferably, this main shaft comprises a main tapping.
Description of drawings
Fig. 1 is the structural representation of the lathe of prior art;
Shown in Figure 2 is the side view of the lathe of prior art;
Shown in Figure 3 is the machine tool structure sketch map of the utility model.
The specific embodiment
Below in conjunction with embodiment the utility model is described further.
As shown in Figure 3, the lathe of the utility model comprises: main tapping 21, knife striking cylinder 23, the sleeve pipe 22 of forging a knife, main shaft 24, cutter 25.In the present embodiment, the center of main shaft 24 is a hollow structure, and cooling fluid is cooled off cutter via the center of said main shaft, and arrow is depicted as the flow path of cooling fluid among the figure.Its principle is that high-pressure coolant is ejected on the cutter through the alignment of shafts; Cooling effect is good, prevents that cutter and workpiece from producing thermal deformation, and can keep the stable accuracy of cutter; Significantly promote stock removal rate and prolong cutter life, more suitable at part to deep hole machining.
The sleeve pipe 22 of forging a knife connects knife striking cylinder 23 and main shaft 24; Knife striking cylinder is forged a knife to alignment of shafts outer ring; Alignment of shafts feedwater, the problem that needs to solve are that it has broken the structure that the alignment of shafts that often has is forged a knife, and sleeve pipe connection knife striking cylinder is forged a knife to alignment of shafts outer ring with forging a knife; This device had both satisfied the function of alignment of shafts feedwater, had solved the problem that can't forge a knife again.
As the preferred version of the utility model, the center of cutter also is a hollow structure, and cooling fluid is cooled off cutter via the center of cutter.High-pressure coolant to the center cutter ejection, can directly cool off the maximum cutting point of caloric value through the alignment of shafts, significantly promotes stock removal rate and prolongs cutter life.
