Description

Switching Bolt Shifter for Right Angle Vise

The present invention relates to an opening and closing bolt moving device for a right-angle vise, more specifically to be able to quickly fix the fixing of the workpiece during welding or other machining operations of the workpiece to maintain a right angle.

In general, for welding or other machining of the workpiece is fixed with a vise to prevent the workpiece from flowing. In particular, when the workpiece must maintain a right angle, a right angle vise is used.

Therefore, to fix the workpiece of the right angle vise, the handle is rotated to space the distance between the fixed jaw and the moving jaw, and then the workpiece is positioned between the jaws and the handle is rotated in the opposite direction to fix the workpiece. .

However, in order to adjust the distance between the fixed jaw and the moving jaw, such a conventional right-side vise must rotate the handle for moving the moving jaw.

The present invention has been devised to solve the above problems, the moving jaw is moved according to the size and shape of the workpiece, as well as a right angle vise that can quickly move the opening and closing bolts by screwing the split nut to the opening and closing bolts. An object of the present invention is to provide an open / close bolt moving device.

The opening and closing bolt moving device for the right angle vise designed to achieve the above object is a right angle vise for fixing the workpiece during welding or other machining of the workpiece to maintain a right angle, protrudes on one side of the base and maintains the interior angle 90 ° A fixing jaw, a fixing member installed at the other side of the base and having a concave groove, a through hole inserted into the concave groove of the fixing member and having an opening bolt inserted therein, and hinged to a cover closing the concave groove. The combined rotating member, the split nut is fixed to one side of the rotating member with a pin and the first rotating plate and the second rotating plate elastically installed by the spring, the hinge is coupled to the second rotating plate, the link is coupled to the first rotating plate The lever is installed in the guide hole of, the activity sphere installed at the end of the opening and closing bolt screwed to the split nut, and the activity sphere is hinged It is composed of a moving jaw that is moved by a screw thread and fixes a workpiece.

Hereinafter, with reference to the accompanying drawings showing the present invention 1 to 4 as follows.

1 is a perspective view of a right angle vise installed with a transfer device according to the present invention, Figure 2 is a plan view of a right angle vise is installed a transfer device according to the present invention, Figure 3 is a perspective view of the main portion of the present invention, Figure 4 Referring to this as the front view of the main portion of the invention, the fixing jaw 12, which maintains the interior angle of 90 ° on one side of the base 10 is protruding, the fixing member 20 is installed on the other side of the base 10 The inside of the recess groove 22 is formed.

Rotating member 30 having a through hole 32 in the center is hinged to the concave groove 22, and a cover 34 is coupled to the upper portion of the concave groove 22.

On the other hand, the first rotating plate 42 and the second rotating plate 44 of the split nut 40 is hinged to the pin 46 on one side of the rotating member 30, the first rotating plate 42 and the first The spring 50 is elastically installed in the upper side of the two rotating plate 44.

And the lever 60 is hinged to the upper portion of the second rotating plate 44 and the link 62 is coupled to one side of the lever 60, the other side thereof is formed on the upper portion of the first rotating plate 42 It is inserted in the guide hole 42a.

In addition, the handle 72 is provided on one side of the opening and closing bolt 70 is screwed to the split nut 40 and the activity sphere 80 is formed on the other side and the activity sphere 80 is a moving jaw (90) ) Is formed.

Referring to the effect of the present invention configured as described above are as follows.

After placing the workpiece between the fixed jaw 12 and the movable jaw 90 protruding from one side of the base 10, the lever 60 provided on the upper side of the split nut 40 provided on one side of the base 10 ), As shown in FIG. 4 (b), the link 62 installed at one side of the lever 60 is moved along the guide hole 42a and at the same time the first rotating plate 42 and the first rotating plate 42 of the split nut 40. The second rotating plate 44 is rotated about the pin 46 by the restoring force of the spring 50, the screw coupling force with the opening and closing bolt 70 is released.

At this time, when the handle 72 installed on one side of the opening and closing bolt 70 is pushed toward the fixed jaw 12 side, the opening and closing bolt 70 is moved and the moving jaw 90 hinged to the end thereof is moved together and the workpiece It is in close contact with 100.

In such a state, when the upper lever 60 of the split nut 40 is pressed downward, the first rotating plate 42 and the second rotating plate 44 rotated by the spring 50 are rotated to open / close the bolt 70. Screwed together.

After the split nut 40 and the opening / closing bolt 70 are screwed together, when the handle 72 installed on one side of the opening / closing bolt 70 is rotated, the moving jaw 90 is moved to the workpiece 100 and the workpiece ( 100) is firmly fixed.

On the other hand, when the size and shape of the workpiece 100 is non-uniform, the hinge member is coupled to the rotating member 30 and the moving gear 90 which are hinged to the recess groove 22 of the one side fixing member 20 of the base 10. The active sphere 80 is rotated so that the moving jaw 90 is closely connected to the workpiece 100.

As described above, the present invention facilitates the fixing of a workpiece having a non-uniform size and shape when fixing the workpiece for welding or other machining of a workpiece that must maintain a right angle, and is divided in a moving jaw for fixing the workpiece. Since it is easily moved by the nut is a very useful design that can shorten the working time accordingly.
