Abstract
The invention relates to an improved structure of precision flat pliers which contain a moving plier body and a fixed plier body. The precision flat pliers are characterized in that the precision flat pliers also contain a first jaw plate which is arranged on the upper end of the moving plier body and can move around a vertical rotation shaft, and a second jaw plate fixed on the upper end of the fixed plier body, wherein the left and right ends of the first jaw plate are provided with a pair of arc holes; the first jaw plate is connected with the moving plier body through a pair of articulation bolts matched with the arc holes; and the inside of the first jaw plate is connected with a first clamping strip through a first rotation shaft, and the inside of the the second jaw plate is connected with a second clamping strip through a second rotation shaft. By adopting the improved structure of the invention, the base plane of a workpiece can closely stick to a sizing block, clamping is stable and is convenient to operate and the process that the workpiece is knocked and aligned manually can be eliminated; and the method has advantages of high work efficiency, machining accuracy and yield and good safety.
Description
Technical field
The jaw that the present invention relates to a kind of flat-nose pliers improves structure.
Background technology
The general flat-nose pliers structure of prior art; during processing thin-walled part; because workpiece baseplane and parallels are fitted not exclusively; it is poor that the part both sides depth of parallelism appears in regular meeting; the operator need strike the school part by rule of thumb increases the applying degree; the situation that the part two sides depth of parallelism is low is prone to also in the process that workpiece is loosening to be caused scrapping, and its work efficiency is low, poor stability.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of improvement structure of precision flatnosed pliers, and it clamps the workpiece baseplane and parallels can fit tightly, and clamps firmly, and is easy to operate, the work efficiency height.
The present invention adopts following technical scheme: comprise moving caliper and fixed clamp, it is characterized in that: also comprise with the movable second jaw sheet that is arranged at the first jaw sheet of moving caliper upper end and is fixed in the fixed clamp upper end of vertical rotating shaft, both ends, the first jaw sheet left and right sides are provided with a pair of arcuate socket, the first jaw sheet is connected on the moving caliper by a pair of articulation screw that matches with a pair of arcuate socket, the inboard of the described first jaw sheet is connected with first by first rotating shaft and clamps bar, and the inboard of the second jaw sheet is connected with second by second rotating shaft and clamps bar.Its principle is: after workpiece is put into jaw, the adjustable screw handle advances moving caliper clamping work pieces gradually, progressively propelling along with moving caliper, the second jaw sheet be held the corresponding end face of workpiece and fit tightly, the movable first jaw sheet that is arranged at the moving caliper upper end is finely tuned angle in the moving caliper upper end around vertical rotating shaft automatically, the first jaw sheet is fitted tightly with the corresponding end face that is held workpiece, thus, two overproof obtaining of the depth of parallelism that are held end face of workpiece are proofreaied and correct, at this moment, screw a pair of articulation screw of being located on the first jaw sheet, be about to the trim locations of the first jaw sheet on moving caliper and fix; Further propelling along with moving caliper, two clamp bar not only applies ecto-entad to workpiece chucking power, two clamp bar respectively around first rotating shaft and second rotating shaft rotation slightly downwards simultaneously, and workpiece is applied downward thrust, and thrust is combined closely workpiece bottom and parallels.
The present invention has following advantage: 1, the depth of parallelism that is held workpiece end face required to reduce, and to the workpiece of depth of parallelism difference, equally firmly clamping; 2, saved manually to knock the operational sequence of centering workpiece, work efficiency improves greatly; 3, improve machining accuracy, in batches high conformity; 4, yield rate improves, and has reduced production cost; 5, it is easy to operate, has reduced the specification requirement to the workman; 6, good operation safety.

The specific embodiment
As shown in Figure 1 to Figure 3, an embodiment of the present invention comprises moving caliper 1 and fixed clamp 2, it is characterized in that: also comprise with the vertical rotating shaft 3 movable first jaw sheets 4 that are arranged at moving caliper 1 upper end, with the second jaw sheet 5 that is fixed in fixed clamp 2 upper ends, both ends, the first jaw sheet, 4 left and right sides are provided with a pair of arcuate socket 6, the first jaw sheet 4 is connected on the moving caliper 1 by a pair of articulation screw 7 that matches with a pair of arcuate socket 6, the inboard of the described first jaw sheet 4 is connected with first inboard that clamps bar 9, the second jaw sheets 5 by first rotating shaft 8 and is connected with the second clamping bar 11 by second rotating shaft 10.Its principle is: after workpiece is put into jaw, the adjustable screw handle advances moving caliper 1 clamping work pieces gradually, progressively propelling along with moving caliper 1, the second jaw sheet 5 be held the corresponding end face of workpiece and fit tightly, the movable first jaw sheet 4 that is arranged at moving caliper 1 upper end is finely tuned angles in moving caliper 1 upper end around vertical rotating shaft 3 automatically, the first jaw sheet 4 is fitted tightly with the corresponding end face that is held workpiece, thus, two overproof obtaining of the depth of parallelism that are held end face of workpiece are proofreaied and correct, at this moment, screw a pair of articulation screw of being located on the first jaw sheet 47, be about to the trim locations of the first jaw sheet 4 on moving caliper 1 and fix; Further propelling along with moving caliper 1, two clamp bar not only applies ecto-entad to workpiece chucking power, two clamp bar respectively around first rotating shaft 8 and second rotating shaft 10 rotation slightly downwards simultaneously, and workpiece is applied downward thrust, and thrust is combined closely workpiece bottom and parallels.
Equivalent transformation with the similar homogeneous structure of invention all falls into protection scope of the present invention.
