Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Fig. 1 to Fig. 5 shows the sectional view in the front view of lathe headstock, side view and each cross section.Lathe headstock comprises the main shaft body 9 for being connected with machine pillar (not shown) and the bearing for being connected with knife clamping system (not shown) combines; Bearing combination comprise through main shaft body 9 and the rail groove 10 extended along Z-direction and along Z-direction through the axle bed (not shown) of rail groove 10; Rail groove 10 relatively two sides is provided with slide block 1 and conduit on two sides relative to axle bed coordinates.Fig. 6 shows the installation site of rail groove 10 top shoe 1 of lathe headstock bearing combination, and slide block 1 quantity on rail groove 10 is six, and what rail groove 10 was coordinated with axle bed is better, and substantially increase the performance of lathe headstock, stability is better.
Fig. 1 is the front view of lathe headstock, and the front of main shaft body 9 is provided with the circular hole 5 for Exhaust Gas, and circular hole 5 is adjacent with the junction 11 of machine pillar and main shaft body 9; Gas fully discharges the structure not affecting spindle head of lathe, and manually washes the sand during convenient casting.At the other end of main spindle box body 9, namely the other end of the junction 11 of machine pillar and main shaft body 9, arranges rail groove 10, and the cross section of rail groove 10 is circular (as shown in Figure 1).The front of main shaft body 9 is provided with the rectangle kidney slot 6 for dispelling the heat, and rectangle kidney slot 6 one end comprises rail groove 10.Rectangle kidney slot 6 makes main spindle box air permeability improve, and facilitates the assembling of main spindle box parts to regulate, and makes on headstock structure more attractive in appearance.
Fig. 2 shows the side view of lathe headstock inside; Main shaft body 9 inside is cavity and is provided with reinforcement 7, and make main spindle box bulk strength become large, eliminate the harmful effect produced because main spindle box cavity wall is thin, add stiff stability, service life is elongated.The side of main shaft body 9 is provided with the rectangle installing hole 2 for installing belt pulley, convenient, quick when making belt pulley is installed.Sectional view Fig. 3 along the A-A section line of Fig. 1 shows the side of lathe headstock, and the side view of rail groove 10 is rectangle, and be circular in conjunction with rail groove 10 cross section in front view 1, the shape of rail groove 10 is cylindrical.On the extended line of the circular hole 5 (as shown in Figure 1) in main shaft body 9 front and the circular stretch hole 8 position being positioned at main shaft body 9 two ends is provided with for lifting and carrying, main spindle box is made to be easy to carrying and mobile like this.
Fig. 4 is the sectional view of the B-B section line of side view along Fig. 2 lathe headstock inside, the thickness of the chamber outer wall 3 of main shaft body 9 is greater than the thickness of cavity inner wall 4, make main spindle box when casting cooling, avoid the inconsistent and internal stress caused of cooling velocity, make main spindle box produce distortion, thus affect the quality of machine tooling product.
Lathe headstock structural strength of the present invention is large, stability is strong, thermal diffusivity good, the low long service life of lathe headstock cost, effectively can reduce the vibrations of main spindle box during machine tool processing workpiece, and therefore the present invention can be widely used in lathe.
