Detailed Description

In order to make the technical means, creation features, achievement purposes and effects of the technical scheme clearer and easier to understand, the technical scheme is further described in the following combined with specific embodiments:

as shown in fig. 1-3, the present invention provides an automatic shaft processing device, which comprises a base station 1, a first spindle 2 and a second spindle 3 oppositely disposed on a machine station, and a tool post 4 disposed between the two spindles; through holes for shafts to pass through are formed in the first main shaft 2 and the second main shaft 3, and rotating chucks are arranged at the opposite ends of the first main shaft 2 and the second main shaft 3; a material pushing cylinder 5 is further arranged at one end, far away from the second main shaft 3, of the first main shaft 2; the piston rod of the material returning cylinder is opposite to the through hole, and the first main shaft 2 and the second main shaft 3 are both connected to the base platform 1 in a sliding mode along the axial direction of the first main shaft and the second main shaft.

As the scheme is, the utility model discloses a technical thought does: the preliminary feeding is realized through the matching of the material pushing cylinder 5 and the through hole; the clamping and the cutting are switched by switching and clamping two main shafts which are oppositely arranged; both ends centre gripping is rotatory simultaneously, can reduce the radial of axle and rock, and then improve the machining precision.

Preferably, the material pushing cylinder 5 is axially and slidably connected to the base platform 1 along the first spindle 2. The material pushing cylinder 5 can give a certain space between the cylinder and the first main shaft 2 for feeding the shaft through the sliding equipment, so that the pushing distance of a piston rod of the material pushing cylinder 5 is reduced, and the overall length of the cylinder is reduced.

Preferably, the first spindle 2 and the second spindle 3 are also slidably connected to the base 1 in a direction perpendicular to the through hole. The X, Y two-way feeding of the surface of the base platform 1 is realized through the axial and radial sliding connection, and the radial feeding can be inclined to adapt to the situation of multiple processing.
