Abstract
The utility model relates to an improved structure of precision flatnosed pliers, which comprises a movable plier body and a fixed plier body, and is characterized by also comprising a first jaw sheet which is movably arranged on the upper end of the movable plier body through a vertical rotating shaft, and a second jaw sheet which is fixed on the upper end of a fixed plier body, wherein the left end part and the right end part of the first jaw sheet are provided with a pair of arc-shaped holes, the first jaw sheet is connected onto the movable plier body through a pair of hinged screws which are matched with the arc-shaped holes, the inner side of the first jaw sheet is connected with a first clamping strip through a first rotating shaft, and the inner side of the second jaw sheet is connected with a second clamping strip through a second rotating shaft. By adopting the improved structure provided by the utility model, the bottom plane of a workpiece can be tightly fit with a sizing block, the clamping is stable, the operation is convenient, the operation procedure that the workpiece is aligned by manual knocking is omitted, the working efficiency is high, the processing accuracy is high, the rate of finished products is high, and the safety is good.
Description
Technical field
The jaw that the utility model 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.
The utility model content
Problem to be solved in the utility model 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 utility model 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 utility model 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.

Fig. 3 is the A-A sectional structure schematic diagram of Fig. 2.
The specific embodiment
As shown in Figure 1 to Figure 3, a kind of embodiment of the utility model 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.
With the equivalent transformation of the similar homogeneous structure of utility model, all fall into protection domain of the present utility model.
