Description

Inclined plane flat tongs for processing tension spring pull arm

Technical Field

The utility model relates to a frock clamp field, concretely relates to inclined plane flat tongs for extension spring single arm-drag processing.

Background

The tension spring draw arm is a workpiece with an inclined plane, and when the workpiece is used, an ordinary tool clamp cannot perfectly clamp the workpiece, so that clamping is unstable during machining, and machining precision is poor.

SUMMERY OF THE UTILITY MODEL

In order to overcome the not enough of background art, the utility model provides a flat-nose pliers in inclined plane that is used for extension spring single arm-drag processing that centre gripping is stable, and machining precision is high.

The utility model discloses the technical scheme who adopts: the utility model provides a flat-nose pliers in inclined plane for extension spring single arm-drag processing, its includes the relative fixed holder that sets up and moves the holder, it includes base and movable mounting moves the splint on the base to move the holder, the position that the base is located moves the splint rear is equipped with the ejector pin that runs through the setting, it is equipped with a plurality of first arcs of saying to move the splint, the base is equipped with a plurality of second arcs that correspond with first arcs, be equipped with the fixed bolt that moves splint and base position between first arc and the second arc.

The ejector rod is hinged with the movable clamping plate.

The front end of the ejector rod is provided with a spherical surface, and a spherical concave surface is arranged at the position where the movable clamping plate is contacted with the ejector rod.

The ejector rod is in threaded fit with the base.

And a driving piece for driving the linear motion is arranged at the tail end of the ejector rod.

The first arc-shaped groove and the second arc-shaped groove are semicircular or splayed respectively.

The utility model has the advantages that: this technical scheme is through moving splint rotation suitable angle and perfect laminating on the base with movable mounting and treating one side of processing work piece, then exert pressure through the ejector pin, will move splint and base through the bolt in first arc wall and the second arc wall at last and fix, maintain and move the splint and decide the distance between the holder, have the centre gripping stable, advantage that machining precision is high.

Detailed Description

The embodiments of the present invention will be further explained with reference to the accompanying drawings:

as shown in the figure, an inclined plane flat tongs for extension spring arm-drag processing, it includes relative setting decide holder 1 and move holder 2, it includes base 3 and movable mounting moves splint 4 on base 3 to move holder 2, the position that base 3 is located and moves splint 4 rear is equipped with the ejector pin 5 that runs through the setting, it is equipped with a plurality of first arc wall 6 to move splint 4, base 3 is equipped with a plurality of second arc wall 7 that correspond with first arc wall 6, be equipped with the fixed bolt (not shown in the figure) that moves splint 4 and base 3 position between first arc wall 6 and the second arc wall 7.

As shown in fig. 2, the top rod 5 is hinged to the movable clamp plate 4, the movable clamp plate can rotate by a proper angle, the side surface of the movable clamp plate is attached to the side edge of the tension spring pull arm, and then the bolt between the first arc-shaped groove 6 and the second arc-shaped groove 7 can be screwed down.

As shown in fig. 3, the front end of the ejector rod 5 is provided with a spherical surface 8, the position where the movable clamping plate 4 contacts with the ejector rod 5 is provided with a spherical concave surface 9, and the movable clamping plate can be rotated by a proper angle through the matching of the spherical surface and the spherical concave surface, and the effect is the same as that of the hinged mode.

As shown in fig. 3, in this embodiment, the top rod 5 is screwed into the base 3, and the top rod can be screwed into and out of the base, so as to provide locking pressure for the movable clamping plate and the tension spring pull arm.

As shown in fig. 2, in this embodiment, the end of the ram 5 is provided with a driving member 10 for driving linear motion, and the driving member may be a pneumatic cylinder or other power member.

The first arc-shaped groove 6 and the second arc-shaped groove 7 are respectively in a semicircular shape or a splayed shape.
