Detailed description of the invention
In order to make the object, technical solutions and advantages of the present invention clearly, describe the present invention below in conjunction with the drawings and specific embodiments.
As Fig. 1 to Fig. 9, the screw thread process fixture of the present embodiment mainly comprises main body, linear bearing 6, positioner, fixture, top opening.
Wherein, main body comprises support 2, support number is two, toward each other, is arranged on the side plate 11 of support 2 side, is arranged on the panel 1 above support 2.Linear bearing 6 at least two, is preferably also two, and described linear bearing 6 center is through hole, is arranged on panel 1.
Positioner comprises positioning seat 3, is positioned at least two alignment pins on positioning seat 3 lower surface; Hole on alignment pin and workpiece matches setting, with positioning workpieces 8.Positioner also comprises at least two the positioning straight cores 7 protruding from described positioning seat 3 lower surface, and positioning straight core 7 and described linear bearing 6 match setting, load, therefore be preferably also two with the upper end open from described through hole.More specifically, positioning seat 3 comprises crossbeam, and respectively from crossbeam two ends to two of downward-extension pillars, alignment pin is positioned on the lower surface of crossbeam, and the lower surface of two described pillars of positioning straight core difference is given prominence to.
Fixture comprises pressing plate 9 and the housing screw 15 being connected pressing plate 9 and panel 1, and described housing screw 15 is adjustable to make pressing plate 9 workpiece pressing 8.Preferably, the suspension that pressing plate 9 comprises base plate and upwards extends from base plate, described housing screw 15 is positioned on described base plate, the lower surface compressing workpiece 8 of described suspension.More specifically, pressing plate 9 has the groove of kidney-shaped, housing screw 15 enters panel 1 through the groove of kidney-shaped.
Top opening comprises the handle 12 be arranged on side plate 11, one end of described handle 12 is the holding end for operation, the other end is working end, working end is connected with push pedal 10, described push pedal 10 is provided with at least two and backs down straight core 4, described straight core 4 and the described linear bearing 6 of backing down matches setting, is also two, loads with the lower ending opening from described through hole.In operation, handle 12 drives push pedal 10 to move upward to make to back down straight core 4 and enters described linear bearing 6, thus positioning straight core 7 is made described linear bearing 6, reaches the object backing down positioner.
