Abstract
The utility model relates to an oilstone clamp for super-finishing of a bearing groove, which comprises a swinging head body, oilstone mounting holes and a swinging rod, wherein a stepped hole is arranged in the swinging head body along the axial direction, one end of the swinging rod is connected with the swinging head body through the stepped hole, a rotation pair is arranged between the swinging head body and the swinging rod, two oilstone mounting holes are arranged on the swinging head body, the two oilstone mounting holes are arranged on two sides of the axial line of the swinging head body like an inverted V, and an oilstone is fixedly mounted in the oilstone mounting holes. Two positions for mounting the oilstone are arranged in the swinging head body of the oilstone clamp for super-finishing of the bearing groove, thereby being capable of realizing two process steps of rough super and fine super, simplifying the structure of a machine tool and improving the processing efficiency. The holes of the swinging head body and a shaft at the end part of the swinging rod are in clearance fit, and the length of the shaft of the swinging rod is simultaneously slightly larger than that of the mounting holes in the swinging head body, thereby facilitating the adjustment of the position of the swing head body.
Description
Technical field
The utility model relates to machining equipment, and particularly bearing channel lappingout equipment specifically is a kind of oilstone anchor clamps that are used for the super lappingout of bearing channel.
Background technology
The super lappingout processing technology of the bearing channel of bearing (raceway groove) is the whole process technology of a kind of raceway groove (raceway groove) that manufacturing enterprise generally adopts, because its requirement on machining accuracy height has all proposed higher requirement to oilstone and processing technology.Extensive use at present be that the super essence of a preface two-step method is that the super lappingout of bearing channel (raceway groove) is divided into thick super and essence and surpasses two work steps, two super smart and two blocks of oilstones are arranged respectively, overlap driving mechanisms control with two respectively and surpass lappingout and process.Thereby, the machine tool structure complexity, working (machining) efficiency is low.China's utility model patent " microstoning circular cone, cylindrical bearing raceway groove super smart " (March 22 2004 applying date, March 16 2005 Granted publication day, Granted publication CN 2685002Y) a kind of super smart head is disclosed, though two block pressur plates are wherein arranged two oilstones can be installed, but two oilstones need a drive unit separately, and oilstone can only moving linearly in should be super smart, therefore can only be used for the circular cone that bus is a straight line, the lappingout of cylindrical bearing raceway groove, can not be used for bus is the processing of the deep groove ball bearing raceway groove of circular arc line.
Summary of the invention
The purpose of this utility model is to provide a kind of oilstone anchor clamps that are used for the super lappingout of bearing channel, two super smart heads of needs, two cover controlling organizations caused machine tool structure complicated technology problem when the described this oilstone anchor clamps that are used for the super lappingout of bearing channel will solve prior art middle (center) bearing raceway groove lappingout.
The purpose of this utility model is achieved through the following technical solutions: these oilstone anchor clamps comprise yaw body, oilstone installing hole and fork, be axially arranged with shoulder hole along it in the yaw body, fork one end is connected with the yaw body by this shoulder hole, be provided with revolute pair between yaw body and the fork, the yaw body is provided with two oilstone installing holes, these two oilstone installing holes are " eight " font and are located at yaw body axis both sides, and oilstone is fixedly installed in the oilstone installing hole.
Be provided with axle at fork one end, axle matches with shoulder hole in the yaw body, the external diameter of axle is slightly less than shoulder hole small end internal diameter, the length of axle is more bigger than the length of shoulder hole small end, the tip of the axis is provided with screwed hole and is connected with screw, and the external diameter of this screw is greater than the shoulder hole end diameter, less than the shoulder hole outside diameter.
Be provided with screwed hole at oilstone installing hole sidewall, oilstone is fixed in the oilstone installing hole by holding screw.
Be provided with pad between shoulder hole small end face and the screw.
The utility model is compared with prior art, and its effect is actively with tangible.Originally the yaw body that is used for the oilstone anchor clamps of the super lappingout of bearing channel is provided with two positions that oilstone is installed, and can realize thick surpassing with essence surpassing two work steps, simplifies machine tool structure; Improve working (machining) efficiency; Simultaneously, thereby make reciprocally swinging around processed bearing circular arc raceway groove center line, so these anchor clamps can be used for the lappingout processing of deep groove ball bearing raceway groove because fork drive yaw body drives the oilstone that is mounted thereon.Between the hole of a swing body and the axle of swing link end part is matched in clearance, and simultaneously, the length of fork axle is a bit larger tham the length of installing hole in the swing body, is convenient to adjust the position of a swing body.
