Abstract
A thin-arm copper bush dismounting chuck is characterized by comprising a central spindle, a central spindle fixator, a central spindle base, a rotating disk, a base, a rotating handle connection rod, a clamping fixing cap and a tensioning sleeve. The tensioning sleeve comprises a tensioning sleeve rod and a tensioning sleeve cap, wherein the tensioning sleeve rod is located on the left side of the tensioning sleeve cap. The left end of the central spindle penetrates through the central spindle fixator and is inserted into the central spindle base, the left end of the central spindle fixator is connected with the right end of the central spindle base, the clamping fixing cap is arranged at the right end of the central spindle fixator, the left side of the central spindle base is sleeved with the rotating disk, the rotating handle connection rod is arranged on the outer periphery of the rotating disk, the left side of the rotating disk is connected with the right side of the base, the tensioning sleeve is arranged at the right end of the central spindle, and the left side of the tensioning sleeve rod stretches into the central spindle. The central spindle comprises a long central spindle seam, an end portion protrusion, a small protrusion end and a large protrusion end, wherein the central spindle is a long hollow pipe, and a pipe arm of the central spindle is provided with the long central spindle seam. The thin-arm copper bush dismounting chuck can overcome the defect that thin-arm copper bushes slide due to heat expansion during machining.
Description
Technical field
Kit when the utility model relates to the thin arm copper sheathing of a kind of lathe processing, particularly a kind of thin arm copper sheathing discharges chuck.
Background technology
Copper sheathing with inner oil sump is a part that arrives commonly used on motor vehicle, the frequent precision prescribed of this copper sheathing is high, sometimes, the arm of copper sheathing can be very thin, if any the copper sheathing arm thick be 1.285mm, process inner oil sump on the copper sheathing of such thickness, can run into many difficulties, because the arm thickness of workpiece is too thin, and the length of workpiece produces the thermal expansion phenomenon when larger in turning process, workpiece is become flexible and skid, cause work not rotate, workpiece easily damages and scraps like this, and the mandrel that is used for fixing workpiece is also often damaged.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned deficiency of prior art and provide a kind of thin arm copper sheathing to discharge chuck, and it can overcome thin arm copper sheathing because adding the skidding that heating was expanded and occurred man-hour.
The technical solution of the utility model is: a kind of thin arm copper sheathing discharges chuck, and it comprises mandrel, mandrel fixator, mandrel base, rolling disc, pedestal, swing handle connecting rod, the cap that is fixedly clamped, expansion sleeve.
Described mandrel comprises: mandrel slit, end bosses, protruding small end, projection are held greatly, mandrel is a hollow elongated tube, and having the mandrel slit on its pipe arm is that the right-hand member of mandrel has end bosses, end bosses left small and right large, the projection on the right is held than the protruding small end on the left side large 1/20th greatly.
Described expansion sleeve comprises: tensioner loop bar, tensioner cap bag, tensioner loop bar are positioned at the tensioner cap bag left side.
The left end of mandrel passes the mandrel fixator and inserts in the mandrel base, the left end of mandrel fixator is connected to the right-hand member of mandrel base, on the right-hand member of mandrel fixator, the cap that is fixedly clamped is installed, rolling disc is sleeved on the outside, the left side of mandrel base, the swing handle connecting rod is installed on the outward flange of rolling disc, the left side of rolling disc is connected to the right of pedestal, and expansion sleeve is arranged on the right-hand member of mandrel, and the Shen, the left side of tensioner loop bar enters the inside of mandrel.
The utility model compared with prior art has following features: take the lathe spindle taper hole as benchmark, mandrel with it in line, workpiece is placed on mandrel, there is the inside, position of workpiece that the tensioner loop bar is arranged on mandrel, the tensioner loop bar can make the diameter of mandrel change, mandrel also becomes large under the effect of tensioner loop bar when workpiece becomes large because of heating, and workpiece can not skidded
Below in conjunction with the drawings and specific embodiments, detailed construction of the present utility model is further described.
