Detailed description of the invention
Embodiment one:
The present embodiment is a kind of studs thread rolling machine, as shown in Figure 1.The present embodiment comprises: be arranged on the fixing thread rolling splint 7 on lathe bed 1 and slide thread rolling splint 2, described fixing thread rolling splint and slide thread rolling splint are respectively equipped with upper and lower two screw plate fixed bits, and each screw plate fixed bit is respectively equipped with the clamping screw 4,9,10,14 of fixing screw plate 3,6,11,12.
Thread rolling splint is installed the position of screw plate, traditional mode fixes on thread rolling splint and slide thread rolling splint in thread rolling to arrange a screw plate fixed bit respectively, the bottom of screw plate fixed bit is provided with the step (screw plate is normally vertically installed) holding up screw plate, screw plate is placed on step, then screw plate is compressed with clamping screw at top, as shown in Figure 2.If rub a monoblock screw plate of two head threads with the hands, this mounting means compares the position being difficult to adjust screw plate, and the length of workpiece 5 more long being more difficult to adjusts, and common way is that the overall accuracy of manufacture of increase screw plate is to make up the problem in adjustment.If with upper and lower two groups of screw plates 3,6,11,12, two groups of screw plates hang together by centre cushion block 15,16 respectively up and down, although can partly solve the problem adjusted respectively, but because the clamping screw 14 on top is once unclamp, upper and lower two pieces of screw plates are all loosening, carrying out position adjustment with adjustment bolt 13 to fixing screw plate must be very careful, careless slightlyly just the position of having adjusted can be moved, and causes and adjusts unsuccessfully.
The present embodiment arranges upper and lower two screw plate fixed bits respectively in slip or fixing thread rolling splint.A fixing projection is set at the middle part of pit bit that slide thread rolling splint installs screw plate.This fixed projection is without dismountable connections such as bolts, but casting out or the very solid connection such as welding, even if connect with bolt, also by the form being similar to tenon and being inserted in groove, projection can not be moved up and down (for the screw plate vertically installed, the present invention and the screw plate described in the present embodiment are vertical installation) completely.This is because all can reduce the efficiency of locking for clamping screw any movement in the axial direction, and the effect of latch protrusion will stop the movement of clamping screw axis just, therefore, the position of latch protrusion is fixing very necessary.
