Abstract
The utility model provides a workpiece main shaft holding device for spiral bevel gear cutting machine tool, and is characterized in that the rear end of the main shaft which is installed in the main shaft case is provided with a cylinder body. A friction disc is installed on the outer cylindrical surface of the cylinder body. A workpiece clamp piston with a central hole is installed in the cylinder body. The rear end of the cylinder is provided with a circular cylinder plate. A plurality of pistons which are used to support and press the friction disc and two positioning pins which is used to position the friction disc are installed on the cylinder plate. An oil distributing shaft which is used to provide pressure oil for each piston is arranged in the central hole of the workpiece clamp piston. So the existing problem of the deformation of the original thin film cylinder clamping device is solved. The utility model has the advantages o reasonable structure and long service life.
Description
Technical field
The utility model relates to a kind of gear cutting machine, especially a kind of spiral bevel gear processing machine tool work spindle clamping device.
Background technology
Adopt the lathe of method of forming processing spiral bevel gear comparatively general in Gear Factory, its cutting moment of torque is bigger.In order to strengthen the lathe rigidity, all adopt the work spindle clamping device, its structure is that the frictional disk end face that main shaft installs is equipped with film oil cylinder, film deforms under the effect of pressure oil, pressing friction dish, clamping spindle.It adds the work gear process: cutting teeth groove when work spindle is clamped, cut that work spindle soon loosens, divides tooth, clamping again behind the teeth groove, and begin to cut second teeth groove then ... finish up to whole gear is processed.Because the work spindle of this gear cutting machine clamps, loosens rapidly, frequency is high, then film oil cylinder easily produces fatigue, and its elasticity is weakened, and the distortion back is difficult for restoring, and caused to also have residual deformation when loosening, thereby influence divides the tooth motion.
Summary of the invention
The utility model provides a kind of working stability, the spiral bevel gear processing machine tool work spindle clamping device of long service life for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of spiral bevel gear processing machine tool work spindle clamping device, by the main spindle box that has axis hole, be installed in the main shaft that has centre bore in the main spindle box axis hole, be installed in the cylinder body of rear-end of spindle, be installed in the piece-holder piston that has centre bore and chamber, connection front and back oil circuit in the cylinder body, be installed in the piece-holder piston center hole and be communicated with the oil distribution shaft of its oil circuit, the frictional disk of movable set on the cylinder body cylindrical, and the oil cylinder that clamps frictional disk is formed, it is characterized in that: described oil cylinder be one that be installed in the cylinder body end face and have an annular cylinder dish of joining the hole with piece-holder piston cunning, the end face of oil cylinder dish is along circumferential uniform several plunger shaft that is shaped on, the piston of roof pressure at the frictional disk end face is installed in each plunger shaft, and back-moving spring, be communicated with oil circuit between plunger shaft and oil distribution shaft; Two alignment pins and retainer spring thereof also are installed on the end face of oil cylinder dish, and corresponding two alignment pins are shaped on two pin-and-holes that are complementary on the frictional disk end face.
The utility model can also adopt following technical measures:
The plunger shaft that described oil cylinder dish is shaped on is 16, and the corresponding piston of installing also is 16.
Be inlaid with the bigger friction plate of coefficient of friction on the other end of described frictional disk.
Advantage and the good effect that the utlity model has are: owing at the end face of the frictional disk of main shaft the annular cylinder dish is installed, be evenly equipped with the piston of more than ten roof pressure at the frictional disk end face on the oil cylinder dish, realize that main shaft clamps; In addition, also being inlaid with the bigger friction plate of coefficient of friction in the face of on the frictional disk end face of main spindle box, make the clamping force of main shaft bigger, solved the problem of former film oil cylinder clamping device residual deformation, the utility model also has rational in infrastructure, the advantage of long service life.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, the main shaft 1 that has centre bore 13 is installed in main spindle box 2 centre bores, driven wheel 10 is installed on the main shaft external cylindrical surface, rear-end of spindle is equipped with cylinder body 7, frictional disk 3 is installed on the external cylindrical surface of cylinder body, and the inner chamber of cylinder body is installed the piece-holder piston 11 that has center screw 12.Be shaped on the oil circuit in chamber 18,19, conducting front and back respectively on the piece-holder piston inner wall, the oil distribution shaft 6 that is communicated with pressure oil is installed in the piece-holder piston center hole.At cylinder body 7 tail ends one annular cylinder dish 5 is installed in order to clamp frictional disk, oil cylinder dish end face upper edge is the uniform piston 4 of 16 roof pressures on the frictional disk end face that be equipped with circumferentially, and oil pocket 15 and the back-moving spring 14 that is communicated with oil distribution shaft all arranged at the bottom of each piston.Also uniform alignment pin 8 and the retainer spring 16 thereof that 2 relative frictional disk location are installed is shaped on the locating hole 17 that is complementary with it on the oil cylinder dish end face on the frictional disk end face of corresponding alignment pin.In order to strengthen the fastening positioning action of frictional disk, on the other end of frictional disk, be inlaid with the bigger friction plate of coefficient of friction 9, so that frictional disk produces bigger frictional force when being pressed in the main spindle box end face to main shaft.
Operating principle:
When oil distribution shaft 6 during to ante-chamber 18 fuel feeding of piece-holder piston 11, move behind the piece-holder piston, workpiece is clamped by the anchor clamps that are packed in the piece-holder piston screw 12; When oil distribution shaft during to back cavity 19 fuel feeding of piece-holder piston, the reach of piece-holder piston, workpiece is loosened.
When oil distribution shaft during to piston 4 oil pockets 15 fuel feeding of oil cylinder dish 5, piston roof pressure frictional disk 3 compresses the end face of main spindle box 2, and main shaft is clamped fixing; When oil distribution shaft stopped plunger shaft fuel feeding to the oil cylinder dish, piston loosened roof pressure power, and main shaft can drive transposition or calibration by gear 10.
