Description
Technical field
The present invention relates to a kind of turning clamp, particularly relate to a kind of turning irregular contour and the fixture of the interior hole machined of the softer part of material.
Background technology
In machining, under normal circumstances, during turning, be the one end utilizing the scroll chuck of lathe itself to carry out Clamp blocks, turnery processing is carried out to the other end; Or change the three-jaw formal dress of scroll chuck into the anti-pawl that is installed, and then prop up from the endoporus of part to be processed with the three-jaw of chuck and realize location clamping thus part is processed.Above-mentioned processing method is adapted to: the comparatively hard and part of profile rule of material, or the enough anti-pawl of the endoporus of part to be processed stretches into.But softer for the material such as magnesium, aluminium, endoporus is less and the part that profile is irregular, with the clamping of chuck three-jaw or anti-pawl stretching, the axiality of the part after part deformation, processing is all easily made to require to be guaranteed, add that magnesium, aluminium etc. are higher compared with the accessory turning rate request of softwood matter, three-jaw is clamped, easily make part fly out, process safety coefficient is lower.
Summary of the invention
The technical problem to be solved in the present invention, in order to overcome the deficiency of above-mentioned existence in Tutrning Process, provides a kind of turning clamp, has both ensured the technical requirement of the axiality of part, also ensures the security of process simultaneously.
In order to solve the technical problem of institute's art above, the present invention takes following technical scheme:
A kind of turning clamp, comprise main shaft, main shaft one end is the Morse taper shank coordinated with lathe spindle internal taper hole, the main shaft other end is set with ring flange, ring flange is installed with fixed head, fixed head is set with sleeve, sleeve right-hand member is pressed with cover plate, cover plate is provided with the through hole at a Ge Guo center, and its diameter is greater than the diameter of bore of part to be processed.
In order to part to be processed is located, fixed head is provided with the convex axle with inner bore of part matched in clearance.
In order to ensure the axiality requirement of the part after processing, the Morse taper shank on main shaft must ensure coaxial with the convex axle on fixed head.
In order to eliminate the error in part length, the external diameter of sleeve right-hand member has L shape groove up and down, can finely tune the degree of depth that sleeve compressed into by cover plate; L shape groove is greater than bolt external diameter; In order to the irregular part monolateral external diameter in the middle of sleeve got out of the way on part has the groove of stepping down; For ensureing being fixedly connected with of sleeve and fixed head, the step cylindrical of sleeve left end endoporus and fixed head is interference fit.
In order to clamp the part to be processed be contained on fixture, cover plate is step cover plate, and cover plate boss face is pressed on workpiece, and the two sides of cover plate are provided with bolt hole, and bolt is tightened in bolt hole on the cover board through L shape groove, treats processing parts and compresses.
In order to easy to operate, play anti-skidding effect, the cylindrical of cover plate is provided with nicking.
The invention provides a kind of turning clamp, solve the softer and problem of irregular accessory turning locating and machining clamping of material, also solve the safety problem in operation simultaneously.Beneficial effect of the present invention: the Morse taper shank on main shaft is coaxial with the convex axle on fixed head, part locating hole to be processed is enclosed within the convex axle of fixed head, the endoporus treating processing parts is again processed, and can ensure the axiality requirement of part locating hole and machining hole; Part is sleeved on the convex axle of fixed head, and cover plate is fitted on part, due to face contact, can ensure in parts fixation process indeformable; The sleeve that fixed head is set with outward, wraps in part in sleeve, in Vehicle Processing High Rotation Speed situation, can ensure that part can not fly out, ensure that the security of processing.Structure of the present invention is simple, and clamping is reliable, and production efficiency is high, and production security is high, can wide popularization and application.
