Abstract
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
The invention belongs to processing tool technical field, be specifically related to a kind of processing tool for bearing block.
Background technology
Bearing block is the common part of one on lathe, and the bearing block required precision on precision machine tool is high, and coaxiality error is smaller, when it requires as 0.005mm, processes more difficult.If by general gap axle, because part tolerance band is by gap when causing part to coordinate with axle, the bearing block axiality after processing will be caused to require to exceed the requirement of drawing regulation, bring certain trouble to follow-up work.
Summary of the invention
For problems of the prior art, the object of the invention is to design provides a kind of processing tool for bearing block.
The described processing tool for bearing block, it is characterized in that comprising axle, the middle part of described axle is set to cone structure, the middle part of axle is arranged with the ball frame matched with cone structure, described ball frame is provided with locating hole, heart the tip of the axis is arranged with the rotating nut for clamp shaft bearing, and the perpendicularity that described vertebral body structure and bearing block locate end face is 0.001-0.003mm.
The described processing tool for bearing block, the shoulder face that it is characterized in that described rotating nut is provided with rubber blanket.
The described processing tool for bearing block, is characterized in that the edge of described ball frame is provided with some steel balls.
Novel structure of the present invention, reasonable in design, by vertebral body structure and the ball frame of setting, the vertebral body structure realized in the middle part of ball frame and axle clamps, and then realize the locking of bearing block, bearing block is located reliable, and then make machining shaft bearing cylindrical precision high, meet the requirement that bearing block coaxiality error is little.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
The present invention is further illustrated below in conjunction with Figure of description.
As shown in Figure 1, the present invention is used for the processing tool of bearing block, comprise axle 1, the middle part of axle 1 is set to cone structure 2, and the middle part of axle 1 is arranged with the ball frame 3 matched with cone structure 2, and ball frame 3 is provided with locating hole, the end of axle 1 is arranged with the rotating nut 5 for clamp shaft bearing 4, the perpendicularity that vertebral body structure 2 and bearing block 4 locate end face is 0.001-0.003mm, and the shoulder face of rotating nut 5 is provided with rubber blanket 4, and the edge of ball frame 3 is provided with some steel balls.
Operation principle of the present invention, first, is sheathed on bearing block 4 in axle 1, then screws rotating nut 5, the shoulder mouth of rotating nut 5 is contacted with rubber blanket 4, plays preloaded bearing seat 4.When rotating nut 5 rotates further, it can promote ball frame 3, and ball is moved to the left along the conical surface simultaneously, until to engagement shaft bearing 4, make bearing block 4 radial location, now, bearing block 2 locked by rubber blanket 6.Facts have proved, after adopting the axle 1 of high-precision band cone structure 2, bearing block 4 is located reliably, and machining shaft bearing cylindrical precision is high, meets the requirement that bearing block 4 coaxiality error is less than 0.005mm.
In order to meet the required precision of bearing block 4 axiality, not only have employed the axle 1 of high accuracy band cone structure 2, but also have employed ball frame 3, bearing block 4 being located more reliable.Following technological requirement must be met when making axle 1: the requirement gap that ball frame 3 and axle 1 cooperatively interact is better less, therefore, adopts high-precision matched in clearance simultaneously; In order to not affect the radial location precision of bearing block 4, the locating hole of ball frame 3 should be not more than 0.003mm with the perpendicularity of both ends of the surface, and the cone structure 2 of axle 1 and bearing block 4 locate the perpendicularity of end face between 0.001-0.003mm.
Claims (3)
1. for the processing tool of bearing block, it is characterized in that comprising axle, the middle part of described axle is set to cone structure, the middle part of axle is arranged with the ball frame matched with cone structure, described ball frame is provided with locating hole, heart the tip of the axis is arranged with the rotating nut for clamp shaft bearing, and the perpendicularity that described vertebral body structure and bearing block locate end face is 0.001-0.003mm.
