Abstract

The invention discloses a pair of split type flat tongs adjustable in angle. The split type flat tongs adjustable in angle can clamp workpieces with slopes on the outer surfaces. The split type flat tongs adjustable in angle comprise a base. A center shaft and a semicircular board are arranged on one side of the base. The semicircular board is arranged on the center shaft and can rotate around the center shaft. An annular T-shaped groove is formed in the base around the center shaft. A plurality of first T-shaped groove bolts are evenly distributed on the semicircular board. The head of each first T-shaped groove bolt is located in the annular T-shaped groove. The rod portion of each first T-shaped groove bolt penetrates through the annular T-shaped groove to be in threaded connection with the semicircular board and can be screwed with a corresponding first nut. A first clamp is fixed to the semicircular board. Second clamps which can move along the base in parallel and can achieve self-locking are arranged on the other side of the base. A workpiece clamping part is arranged between the first clamp and the second clamps.

Description

Angle adjustable Split type flat tongs
Technical field
The present invention relates to a kind of machine tool accessories, be specifically related to a kind of angle adjustable Split type flat tongs.
Background technology
Flat-nose pliers is a kind of universal fixturing, is usually used in fixing miniature workpiece, is the annex of milling machine, drilling machine, and be fixed on the workbench of milling machine or drilling machine during use, holding workpiece carries out Milling Process to workpiece.Existing flat-nose pliers, comprise two clamps, it is the clamping part of workpiece between two clamps, one of them clamp is fixing, conveniently workpiece loading and unloading, and another is moveable, because two clamps have specific clamping face, therefore can only clamp the workpiece of given shape, then cannot clamp for the bevelled workpiece of some outer surface tools, use limitation large.
Summary of the invention
The invention provides a kind of angle adjustable Split type flat tongs clamping the bevelled workpiece of outer surface tool, to expand the scope of application of flat-nose pliers.
This programme is as follows: angle adjustable Split type flat tongs, comprise base, the base of side is provided with central shaft and semi-circular plate, semi-circular plate is arranged on center shaft can central axis, base is the center of circle is provided with ring-type T-slot with central shaft, semi-circular plate is evenly equipped with multiple first T-slot bolt, the head of the first T-slot bolt is positioned at ring-type T-slot, the bar portion of the first T-slot bolt is threaded with semi-circular plate through ring-type T-slot and by the first nut screwing clamping, semi-circular plate is fixed with the first clamp, the base of opposite side is provided with and can moves in parallel along base and the second clamp of self-locking, it is the clamping part of workpiece between first clamp and the second clamp.
This programme operation principle is as follows: during the workpiece of clamping shape rule, first clamp is without the need to rotational angle, the jaw of the first clamp is directly relative with the jaw of the second clamp, semi-circular plate is fixed by the first T-slot bolt tightening, workpiece is placed between the first clamp and the second clamp, locks the second clamp after mobile second clamp top tight workpiece.
During the bevelled workpiece of clamping outer surface band, semi-circular plate is made to take central shaft as axle, certain angle is turned over along ring-type T-slot, the jaw gradient of the first clamp and workpiece slope are matched, tightens the first T-slot bolt, fixing semi-circular plate and the first clamp, workpiece is put between the first clamp and the second clamp, mobile second clamp, until the second clamp top tight workpiece self-locking, positioning workpieces.
To sum up, the present invention both can clamp common shape regular workpiece, also can clamp the bevelled irregular workpiece of outer surface tool, have more practicality.
Further, the conveniently movement of the second clamp and self-locking, the base of opposite side is provided with two parallel strip T-slots, the both sides of the second clamp are provided with the second T-slot bolt, the head of the second T-slot bolt is positioned at strip T-slot, and the bar portion of the second T-slot bolt is threaded with the second clamp through strip T-slot and by the second nut screwing clamping.
Further, base bottom both sides are provided with two positioning keys.Can be located with lathe by positioning key, locate more stable.
Further, be provided with positioning screw at the end face of the second clamp, positioning screw is threaded with the second clamp.During holding workpiece, by rotating positioning screw, making the end of positioning screw be against workpiece end face, workpiece is located further, ensure the accuracy of workpiece centering simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: base 1, central shaft 2, semi-circular plate 3, ring-type T-slot 4, first T-slot bolt 5, first clamp 6, trip bolt 7, strip T-slot 8, second clamp 9, second T-slot bolt 10, positioning screw 11 and workpiece 12.
Angle adjustable Split type flat tongs as shown in Figure 1: base 1 two bottom sides is provided with two positioning key (not shown)s, for fixing with lathe.The base 1 of side is provided with central shaft 2, semi-circular plate 3 empty set can be rotated by central shaft 2 on central shaft 2, on base 1 with central shaft 2 for the center of circle is provided with ring-type T-slot 4, semi-circular plate 3 is evenly equipped with multiple first T-slot bolt 5, the head of the first T-slot bolt 5 is positioned at ring-type T-slot 4, the bar portion of the first T-slot bolt 5 is threaded with semi-circular plate 3 through ring-type T-slot 4 and by the first nut screwing clamping, semi-circular plate 3 is fixed with the first clamp 6 by trip bolt 7.
The base 1 of opposite side is provided with two parallel strip T-slots 8, the both sides of the second clamp 9 are provided with the second T-slot bolt 10, the bar portion that the head of the second T-slot bolt 10 is positioned at strip T-slot 8, second T-slot bolt 10 is threaded with the second clamp through strip T-slot 8 and by the second nut screwing clamping.Be provided with positioning screw 11 at the end face of the second clamp 9, positioning screw 11 is threaded with the second clamp 9.It is the clamping part of workpiece between first clamp 6 and the second clamp 9.
