For optimizing the lubricating quality of roller in prior art, normal needs arrange oilhole or oil groove on the inner ring and outer ring of self-aligning roller bearing, but inner ring and the fixing of outer ring are showed by the deck of chuck and similar bench vice in above process, chuck and the irregular working face of deck will inevitably cause the side of inner ring and outer ring or end face to produce impression, affect the fit quality of self-aligning roller bearing and bearing block or axle.
Summary of the invention
For solving the problem, bearing oil processing holder provided by the invention solves problem by following technical essential: bearing oil processing holder, comprise terminal pad, baffle plate, nut, screw mandrel and at least two connecting bolts, described terminal pad is provided with the bolt hole that quantity is equal with connecting bolt quantity, connecting bolt lays respectively in a bolt hole, any one end of terminal pad is also provided with circular groove, screw mandrel is fixedly connected with terminal pad, and the axis collinear of screw mandrel and groove, baffle plate becomes matched in clearance with screw mandrel, and baffle plate is positioned on terminal pad and arranges reeded one end, nut becomes to be threaded with screw mandrel, and baffle plate is between nut and terminal pad, for ease of the installation of terminal pad, described terminal pad is also provided with pin hole, alignment pin is provided with in described pin hole.
Concrete, the terminal pad arranged is fixedly connected with the chuck seat of lathe by connecting bolt, the groove be arranged between baffle plate and terminal pad is the FX of bearing outer ring, and baffle plate is achieved by the adjustment position of engagement of nut on screw mandrel the compression of bearing outer ring.In the present invention, owing to being directly fixedly connected on chuck seat by terminal pad, this makes the contact surface of terminal pad and chuck seat and lathe spindle axle center have good perpendicularity, is conducive to the turnery processing precision of bearing outer ring like this; Bearing outer ring and contact surface of the present invention are large, are conducive to preventing processing impression, be beneficial to bearing finally with bearing block or axle coordinate installation quality.Impel lathe spindle to vibrate for reduction or elimination the present invention produce centrifugal force in the course of the work, described terminal pad is in the form of annular discs, the axis of screw mandrel and the axis collinear of terminal pad.For avoiding connecting bolt to bring impact to bearing outer ring installation, described bolt hole is concentric different diameter hole, and connecting bolt is hexagon socket head cap screw, and the screw cap end end of connecting bolt is between the two ends end face of terminal pad.
For strengthening the anti-loosening property of nut, the screw thread on described screw mandrel is fine thread.
For ease of changing the screw mandrel of different length according to the width of the quantity or bearing outer ring that are set in the bearing outer ring on screw mandrel, described terminal pad is provided with screw hole, is provided with internal thread in described screw hole, screw mandrel becomes to be threaded with terminal pad.
The present invention has following beneficial effect: the terminal pad of setting is fixedly connected with the chuck seat of lathe by connecting bolt, the groove be arranged between baffle plate and terminal pad is the FX of bearing outer ring, and baffle plate is achieved by the adjustment position of engagement of nut on screw mandrel the compression of bearing outer ring.In the present invention, owing to being directly fixedly connected on chuck seat by terminal pad, this makes the contact surface of terminal pad and chuck seat and lathe spindle axle center have good perpendicularity, is conducive to the turnery processing precision of bearing outer ring like this; Bearing outer ring and contact surface of the present invention are large, are conducive to preventing processing impression, be beneficial to bearing finally with bearing block or axle coordinate installation quality.
