Description
Technical Field
The utility model relates to a novel eccentric rack anchor clamps belongs to machining technical field.
Background
The eccentric rack part plays an important role in mechanical transmission and is widely applied in the field of machinery. In order to ensure the accurate transmission of the eccentric rack, the high requirement is provided for the machining precision of the lathe. The most convenient clamping mode of a lathe usually adopts a three-jaw self-centering chuck which is only suitable for processing revolving body parts such as shafts, and eccentric workpieces with irregular shapes like eccentric racks cannot be clamped due to inconsistent centers, so that the revolving body parts can only be processed by adopting a four-jaw single-action chuck. The traditional four-jaw chuck is used for processing the eccentric rack, and three difficulties exist: firstly, the alignment of the eccentric workpiece takes long time which is far longer than the processing time of the eccentric workpiece; secondly, the eccentric rack is difficult to clamp due to irregular shape, and can deviate in processing when the eccentric rack is stressed improperly, so that the eccentric rack is an unqualified product; thirdly, the precision requirement of the workpiece is high, and the requirement on the skill level of an operator is also high.
SUMMERY OF THE UTILITY MODEL
In order to solve the deficiencies existing in the prior art, the utility model provides a novel eccentric rack clamp makes processing eccentric rack become simple swift, and guarantee machining precision that again can be fine has improved work efficiency and operating mass with rated load.
The utility model provides a technical scheme that its technical problem adopted is: a novel eccentric rack clamp comprises a clamp body and a positioning screw; the clamp body is the cylinder type, and the square hole has been seted up to the clamp body front end, and the distance of the bottom surface of the clamp body square hole and lateral wall to the clamp body axle center is unanimous with the rack face of eccentric rack and the distance of side to the eccentric shaft axle center, and two screw holes have been seted up to the clamp body square hole upper surface, and threaded hole is equipped with set screw, and clamp body square hole rear end is equipped with the end cap, and square opening has been seted up to the end cap, and the bottom surface and the lateral wall of square opening correspond with the bottom surface and the lateral wall of the clamp.
The tail end of the eccentric rack is provided with an eccentric shaft, the eccentric rack is placed in a square hole of the clamp body, the front end of the eccentric rack is propped against the plug, a positioning screw is screwed down to position the eccentric rack, the clamp body is clamped on the three-jaw chuck, and the distance from the bottom surface and the side wall of the square hole of the clamp body to the axis of the clamp body is consistent with the distance from the rack surface and the side surface of the eccentric rack to the axis of the eccentric shaft, namely the axis of the clamp body is consistent with the axis of the eccentric shaft.
The utility model has the advantages that: the alignment is quick and accurate, and the clamping of being convenient for alleviates intensity of labour, and simple structure uses the utility model discloses the production efficiency more than 10 times has been improved than traditional processing method, makes processing eccentric rack become simple swift, and assurance machining precision that again can be fine has improved work efficiency and operating mass with rated load.
