TECHNICAL FIELD

[0001] The utility model relates to lathe spindle machining technical field especially lathe spindle machining's processing fixture. BACKGROUND

[0002] Lathe spindle refers to the shaft that drives workpiece or tool rotation on the machine tool, which is mainly used to support transmission parts such as gears, pulleys, etc. in the machine, and transmit motion and torque. During the machining process of lathe spindle, clamps are needed to clamp and fix the lathe spindle.

[0003] For example, patent number CN218136487U discloses a lathe spindle machining processing fixture, which comprises a base, a first side plate fixedly connected to the top of the base, a first thimble fixedly connected to one side of the first side plate, a clamping mechanism arranged on the base, the clamping mechanism comprising two fixed plates fixedly connected to the top of the base, and the two fixed plates are arranged front and back, a first rotating rod penetrates through one side of the fixed plate at the rear through a first bearing, and a first rocker is fixedly connected to one end of the first rotating rod. In the utility model, the first rocker can drive the bidirectional threaded rod to rotate, thereby driving the two clamping blocks to move relatively, so as to clamp the front and back of the spindle. The second rocker can drive the bolt to rotate, thereby driving the pressing plate to press the top of the spindle tightly, so as to clamp the spindle in multiple directions and improve the clamping effect. The processing fixture in the patent lacks pre-support positioning function for the lathe spindle, and lacks auxiliary support when the lathe spindle contacts the thimble, which makes the positioning of the lathe spindle more difficult and prone to deviation and inclination, affecting the subsequent machining.

[0004] Therefore, in view of the problem that the lathe spindle machining processing fixture lacks pre-support positioning function, which makes the positioning of the lathe spindle more difficult and prone to deviation and inclination, a lathe spindle machining processing fixture can be designed.
