Abstract
The utility model discloses a die -stock, tightly spend the adjusting sleeve including handle, front tooth, front tooth clamping device, screw rod fastening ball plung and steel ball, front tooth clamping device is " protruding " style of calligraphy, front tooth clamping device portion open be equipped with on the lateral wall that has front tooth groove, lower extreme the fixed screw of handle and with the fixed screw of front tooth of front tooth groove intercommunication, open the screw vent who has with front tooth groove intercommunication along front tooth clamping device's axis, just it has hemispherical steel ball hole to open on the lateral wall of front tooth clamping device's upper end, and this utility model reasonable in design simple structure introduces the effect that fastening and positioning screw had been played effectively in the design of screw rod fastening ball plung, prevents the screw thread asymmetrical problem of extracing tooth that arouses at the front tooth in -process because of the screw rod slope.
Description
Technical field
This utility model is related to a kind of hardware tool, more particularly to a kind of die-stock.
Background technology
Pincers worker is frequently encountered the metal round rod for needing manual articulation screw thread in daily production work, generally operation be by
Screw die loads in die-stock, the oblique angle of the guide cone face alignment pieces round bar of screw die, ensures with maneuver completely by workman
Circular die end face is vertical with axis of workpiece, and this simple operations needs pincers worker operator to have very skilled operation, because
Tiny error just can cause the thread form of screw die not just, the quality problems such as rotten tooth, so as to cause yield rate low, screw die uses the longevity
Life also can shorten, i.e., the existing die-stock overwhelming majority lacks the locating guide device of round bar, and causes during screw die
Round bar and screw die off plumb problem.
Utility model content
Technical assignment of the present utility model is to provide a kind of die-stock for above prior art deficiency.
This utility model solves the technical scheme that its technical problem adopted：A kind of die-stock, including handle, plate
Tooth, screw die clamping device, screw rod fastening positioning ball and steel ball tightness adjusting sleeve, the screw die clamping device is in " convex " font,
The bottom of the screw die clamping device is provided with screw die groove, the side wall of lower end is provided with the handle fixing threaded hole that connects with screw die groove and
Screw die fixing threaded hole, the screw vent connected with screw die groove is provided with along the axis of screw die clamping device, and the screw die is clamped
The steel ball hole of cylindrical shape is provided with the side wall of the upper end of device.
Further as optimization, the steel ball hole position receives that to form taper steel ball spacing in the part of screw vent side
Circle.
Further as optimization, the difference of the cylindric steel ball bore dia and screw rod fastening positioning diameter of the steel ball is 0.1-
0.5mm, the screw rod fastens positioning ball（5）The difference of diameter and taper steel ball spacing collar diameter is 0.5mm.
Further as optimization, the inside top of the steel ball tightness adjusting sleeve is in inverted cone.
Further as optimization, the screw die fixing threaded hole on the screw die clamping device is evenly distributed on screw die clamping device
Side wall on, and two adjacent screw die fixing threaded holes are equal with the angle being centrally formed of screw die clamping device.
Utility model simple structure reasonable in design, introduce screw rod fastening positioning ball design effectively serve fastening and
The effect of positioning screw, prevents the asymmetric problem of exodontia screw thread caused because of screw rod inclination during screw die.

Specific embodiment
Workflow of the present utility model is described below with reference to Figure of description：
As depicted in figs. 1 and 2, a kind of die-stock, including handle 3, screw die 6, screw die clamping device 1, screw rod are fastened
Position steel ball 5 and steel ball tightness adjusting sleeve 2, the screw die clamping device 1 is in " convex " font, the bottom of the screw die clamping device 1
The side wall for being provided with screw die groove 11, lower end is provided with the handle fixing threaded hole 7 and screw die fixing threaded hole 9 connected with screw die groove 11, edge
The axis of screw die clamping device 1 is provided with the screw vent 8 connected with screw die groove 11, and the upper end of the screw die clamping device 1
Side wall on be provided with cylindrical shape steel ball hole 10.
Further as optimization, the steel ball hole 10 is located in the part of the side of screw vent 8 to receive and forms taper steel ball limit
Position circle.
Further as optimization, the difference of the cylindric diameter of steel ball hole 10 and the screw rod fastening diameter of positioning ball 5 is
0.1-0.5mm, the screw rod fastens positioning ball（5）The difference of diameter and taper steel ball spacing collar diameter is 0.5mm.
Further as optimization, the inside top of the steel ball tightness adjusting sleeve 2 is in inverted cone 4.
Further as optimization, the screw die fixing threaded hole 9 on the screw die clamping device 1 is evenly distributed on screw die clamping dress
Put on 1 side wall, and two adjacent screw die fixing threaded holes 9 are equal with the angle being centrally formed of screw die clamping device 1.
