When the rotating shaft 4 rotates, the axis of the shaft part on which the first shaft clamping arm 5 moves is collinear with the axis of the chuck, the shaft part on the second shaft clamping arm 6 is located right above the feeding mechanism 2, at this time, the clamping jaw cylinder of the second shaft clamping arm 6 is opened, and the shaft part 300 falls on the feeding mechanism 2.

Feeding mechanism 2 includes hold-in range slip table 2a and guide board 2b, hold-in range slip table 2a level sets up in the bottom of feed mechanism 1, hold-in range slip table 2a is used for the level to outwards carry finished shaft class part, guide board 2b slope sets up, lower one end setting is at hold-in range slip table 2 a's feed end and with hold-in range slip table 2 a's upside surface parallel and level, guide board 2b higher one end is located and moves the material mechanism under, guide board 2b is used for making the axle type part that moves the material mechanism and unload slowly roll to hold-in range slip table 2 a's feed end. Feeding mechanism 2 still includes riser 2c and gas spring 2d, riser 2c sets up the feed end at hold-in range slip table 2a along vertical direction, the lower one end of guide board 2b is articulated with riser 2 c's upper end, and gas spring 2 d's both ends are articulated with guide board 2b and riser 2c, can make guide board 2b elasticity set up the feed end at hold-in range slip table 2a through riser 2c and gas spring 2d, and then can cushion finished shaft class part to guide board 2 b's impact force.

The lathe body 100 may be a general lathe or a numerically controlled lathe.

Example two

In this embodiment, the feeding mechanism 200 is provided detachably to the lathe body 100, the height of the rotary shaft 4 is adjustable, the distance of the rotary shaft 4 with respect to the feeding mechanism 1 in the horizontal direction perpendicular to the axis of the chuck is adjustable, and the positions of the first chuck arm 5 and the second chuck arm 6 on the mounting plate 5d in the radial direction of the rotary shaft 4 are adjustable, so that the feeding mechanism can be applied to different lathe bodies 100, and when different lathe bodies 100 are to be replaced, it is only necessary to adjust the relative positions of the feeding mechanism 200 and the lathe body 100, the height of the rotary shaft 4, the relative positions of the rotary shaft 4 and the feeding mechanism 1, and the mounting positions of the first chuck arm 5 and the second chuck arm 6 on the mounting plate 5 d.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the invention, but that various changes and modifications may be made without departing from the spirit and scope of the invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
