Problems solved by technology
If a general clearance mandrel is used, due to the tolerance zone of the part, the clearance between the part and the mandrel will be caused, and the coaxiality requirements of the processed bearing seat will exceed the requirements specified in the drawing, which will bring some troubles to the follow-up work

Embodiment Construction
[0009] The present invention will be further described below in conjunction with the accompanying drawings.
[0010] Such as figure 1 As shown, the processing tooling used for the bearing seat of the present invention includes a mandrel 1, the middle part of the mandrel 1 is set as a cone structure 2, and the middle part of the mandrel 1 is provided with a ball frame 3 matched with the cone structure 2, The ball frame 3 is provided with a positioning hole, and the end of the mandrel 1 is provided with a rotating nut 5 for clamping the bearing seat 4. Rubber pads 4 are arranged on the shoulder surface of the ball frame 3, and some steel balls are installed on the edge of the ball frame 3.
[0011] The working principle of the present invention is that first, the bearing seat 4 is sleeved on the mandrel 1, and then the rotating nut 5 is screwed so that the shoulder of the rotating nut 5 is in contact with the rubber pad 4 to pre-tighten the bearing seat 4. When the rotating nu...

The invention discloses a machining tool for a bearing pedestal. The machining tool comprises a spindle, the middle portion of the spindle is of a conical structure and sleeved with a rolling ball frame matched with the conical structure, and a positioning hole is formed in the rolling ball frame. The tail end of the spindle is sleeved with a rotating nut which is used for clamping the bearing pedestal, and the perpendicularity of the conical structure relative to a bearing pedestal positioning end face is 0.001-0.003 mm. The machining tool is novel in structure and reasonable in design; by arranging the conical structure and the rolling ball frame, the rolling ball frame and the conical structure in the middle of the spindle are clamped, and therefore the bearing pedestal is locked; the bearing pedestal is reliably positioned, and therefore the machining precision of the outer circle of the bearing pedestal is high, and the requirement for a small coaxiality error of the bearing pedestal is met.
Description
technical field [0001] The invention belongs to the technical field of processing tooling, and in particular relates to a processing tooling for a bearing seat. Background technique [0002] The bearing seat is a common part on the machine tool. The precision of the bearing seat on the precision machine tool is high, and the coaxiality error is relatively small. When the requirement is 0.005mm, it is difficult to process. If a general clearance mandrel is used, the tolerance zone of the part will cause a gap when the part is matched with the mandrel, which will inevitably cause the coaxiality requirements of the processed bearing seat to exceed the requirements specified in the drawing, which will bring certain troubles to the follow-up work. Contents of the invention [0003] Aiming at the problems existing in the prior art, the object of the present invention is to design and provide a processing tool for bearing seats. [0004] The processing tool for the bearing seat ...
