Abstract
The utility model discloses an auxiliary clamp used in mechanical machining of a slender rod and particularly relates to an auxiliary clamp used for mechanical machining of the head of a rod with a diameter of 16-65mm and a length of 1.5-10m. The auxiliary clamp comprises a cam plate and fixing discs. The cam plate is connected with a shaft of a hydraulic cylinder; three curved grooves are evenly distributed on the cam plate along the circumferential direction; a roller at one end of a lever is inserted into the grooves and a roller at the other end clamps the workpiece; a mandrel at the middle of the lever is connected with the fixing discs; and the fixing disc at the other side is connected with the cam plate through a needle bearing. The auxiliary clamp is convenient to use and high in positioning precision and can improve the coaxiality of the axis of the rod and the axis of the machined part of the head of the slender rod.
Description
Technical field
The utility model is auxiliary dop, the particularly auxiliary clamping of body of rod diameter phi 16～65mm, length range 1.5～10m body of rod head machining of a kind of elongate rod machining.
Background technology
Elongate rod easily causes working position axis and body of rod axis to form angle in mechanical processing process, causes inclined to one side head.Frock bin low precision can't meet the demands.
Summary of the invention
Technical problem to be solved in the utility model provide a kind of easy to use, positioning accuracy is high, can improve the auxiliary dop of elongate rod machining of machining accuracy.
The utility model elongate rod machining is assisted dop, it is characterized in that comprising cam disc, fixed disk, cam disc is connected with the hydraulic cylinder axle, uniform in a circumferential direction three curved grooves of cam disc, in the roller insertion groove of lever one end, the pair of rollers workpiece of the other end tightens, and the axle in the middle of the lever is connected with fixed disk, and the fixed disk of opposite side is connected by needle bearing with cam disc.
The utility model utilizes the swing of cam disc to drive the swing of lever, finish workpiece clamping, unclamp.
Advantage of the present utility model:
Easy to use, positioning accuracy is high, will improve the axiality of elongate rod head working position axis and body of rod axis, particularly body of rod diameter is the auxiliary clamping of φ 16～65mm, length range 1.5～10m body of rod head machining.
