Author design was made one kind is not disassembling below the circumstance of the spare parts, change the whorl hand that is touched help up a kind of device. Attached drawing is in routine, classics regular meeting encounters the phenomenon that the whorl surface of a few spare partses is touched, especially the whorl with a few bigger diameters, disassemble treatment is very difficult, did not pull a tooth accordingly, for this, our design was made one kind is not disassembling below the circumstance of the spare parts, change the whorl hand that is touched help up a kind of device. If attached drawing place is shown, this unit is main by frame body 2, guide screw 3, support roller body 5, whorl lathe tool 8 wait for a few parts to comprise, support roller body 5 can be in frame body slides on the T form slideway of 2, the front of 3 can be in guide screw the roll inside support roller body, gland 4 can make support roller body 5 move along with guide screw axial. When the job, according to the size of whorl diameter, rotational guide screw 3, adjust support roller the position of 6, hold workpiece in the palm 7, reoccupy bolt the whorl lathe tool with 9 close good solid form of tooth of 8 alignment whorl, turn feed of 3 mix up measures guide screw again, handholding handle body of 1 rotational frame, can help the whorl that is touched up stage by stage. Every time feed quantity can be decided according to the level that whorl meets, whorl lathe tool holds Fu Zhenghe concurrently a few cutting action, but purify a few cannot help up metal, this device passes application, the effect is very good, can apply in certain limits, to exceeding the part of limits, should change frame body size only commonly can.
