Description
Technical field
The utility model relates to the technical field of mechanical Set and Positioning, is specifically related to a kind of multipurpose and drives top.
Background technology
Because user has more and more higher requirement to machining accuracy, working (machining) efficiency and processing cost, so impelled clamp technology development.Nowadays, in Machining of Shaft-type Parts, traditional heart carrier clamping and clamping chuck can not meet the requirement of user to part high-precision, high efficiency, low processing cost, drive top advantage in Machining of Shaft-type Parts further obvious.Drive the top and lathe tail centre positioning workpieces in the center of top dependence on it, rely on and drive claw embedding workpiece end face to make it rotate with machine tool chief axis, thus instead of heart carrier and chuck completely, clamped one time can complete each axle journal, end face, grooved and screw thread process, turning milling center can also once complete the processing of keyway and oilhole, working (machining) efficiency improves more than 2 times, axiality and position degree more guaranteed, be thus applied to the turning of axial workpiece, grinding and tooth Profile Machining more and more widely.
It is top that Chinese patent ZL201420178392.X discloses a kind of novel driving, and moving tooth and the driver plate of this technology are one-body molded, the axial workpiece that outside dimension is large or the different part of material hardness, then need to change top, versatility is not high.
Utility model content
It is simple that technical problem to be solved in the utility model is to provide a kind of structure, and precision is high, and interchangeability is strong, and the multipurpose meeting plurality of specifications axial workpiece clamping drives top.
The technical solution realizing the utility model object is: multipurpose drives top, comprise driving-disc, drive claw, top be connected base, described driving-disc is fixedly mounted on the upper end connecting base, it is characterized in that: the upper end radial equipartition of described driving-disc has several grooves, described driving claw is installed in a groove by holding screw, described driving-disc is provided with mounting groove and through hole along axis, described top upper end is through through hole, lower end is arranged in mounting groove, the inwall of described top cylindrical axial plane and through hole is for being slidably matched, fit tolerance is 0.006 ~ 0.01mm, be provided with the pressure-equalizing device of top upwards jack-up in described mounting groove.
Described pressure-equalizing device can use rubber spring.
Described connection base and the corresponding end face of driving-disc are respectively arranged with the ring flange of working in coordination, and two ring flanges are connected by fastening bolt.
The flange of described driving-disc forms central counterbore, the flange of connection base forms the cylinder boss embedding described central counterbore.
Described top lower end base is provided with the auxiliary boss being installed to the counterbore of rubber spring.
Described connection base is provided with the installing hole for installing lathe screw rod.
The driving of the utility model multipurpose is top has following beneficial effect: driving-disc coordinates the driving claw of different size and unlike material hardness can process the axial workpiece of various outer diameter, unlike material hardness; The inwall of described top cylindrical axial plane and through hole is for being slidably matched, and fit tolerance is 0.006 ~ 0.01mm, and quality of fit is high; Driving-disc be connected base and be connected to each other by their respective ring flanges, stability and rigidity higher, safe and reliable; Connect base and be provided with installing hole, can be installed on different lathes, interchangeability is strong, easy for installation, can meet various occasion and use.
