Abstract
The invention discloses a hole machining fixture for a connecting rod. Before clamped and positioned, a connecting rod workpiece is placed on a bench top of a fixture base. One end of the connecting rod is abutted to the end of a limit bar. Two sides of the connecting rod are positioned by a positioning member. A pressure plate is then turned to press to the connecting rod, while fasteners are pressed to the sides of the pressure plate so that the pressure plate is abutted to the connecting rod which is then fixedly abutted to the bench top of the fixture base. When hole machining of the clamped connecting rod workpiece is needed, the fixture is turned over and fixed on the bench top, and hole machining is performed according to the position of a through hole on the fixture base. The fixture is simple in structure and convenient to use and can be used to machine a plurality of through holes for the connecting rod by single clamping. Therefore, production efficiency is improved, errors caused by multiple clamping are avoided, and machining precision is improved.
Description
Technical field
The present invention relates to the tie rod holes clamp for machining.
?
Background technology
The connecting rod workpiece is strip, and along being distributed with a plurality of through holes on its length direction, these a plurality of through holes add and generally adopt one by one setting-out man-hour, beat central point and realize boring, to add in enormous quantities man-hour comparatively loaded down with trivial details, in addition, because this connecting rod workpiece is strip, existing anchor clamps can't carry out a clamping to it and finish porose processing, and working (machining) efficiency is low, and the location of clamping has repeatedly increased manufacturing tolerance.
?
Summary of the invention
The connecting rod workpiece the purpose of this invention is to provide a kind of tie rod holes clamp for machining, so that just can be finished processing through clamped one time.
For achieving the above object, the technical solution used in the present invention is: a kind of tie rod holes clamp for machining, described connecting rod is strip, have a plurality of through holes to be processed on the described connecting rod, described anchor clamps comprise clamp base, be provided with a plurality of through holes corresponding with described a plurality of through holes to be processed on the work top of described clamp base, described anchor clamps also comprise the keeper that is arranged on the described clamp base, can be arranged on rotationally the pressing plate on the described clamp base, be arranged on the fixture that described pressing plate can be pressed on the described clamp base on the described connecting rod, be fixedly installed on the gag lever post on the described clamp base, described keeper is along described length of connecting rod direction distribution and be positioned at described connecting rod two sides, and described gag lever post is positioned at an end of described clamp base work top.
Preferably, described keeper comprises locating piece, described locating piece can be pressed on the bolt on the described clamp base.
As a kind of concrete embodiment, described keeper has four.
Preferably, described fixture is the sub-assembly of bolts and nuts, described bolt can be arranged on the described clamp base rotationally, described pressing plate has a lug boss, has the notch part of offering along the outside in the middle of the described lug boss, described bolt inserts in the described notch part, and described nut is pressed on the described lug boss.
Because the utilization of technique scheme, the present invention compared with prior art has following advantages: the clamp base that has the work top corresponding with the lead to the hole site of connecting rod workpiece to be processed by setting, and in this clamp base pressing plate is set, keeper, fixture and gag lever post, when needs carry out clamping and positioning to the connecting rod workpiece, this connecting rod is placed on the work top of clamp base, one end of this connecting rod and the end of gag lever post are inconsistent, keeper forms the location to the two sides of this connecting rod, rotary pressure plate is pressed on this connecting rod it again, at this moment fixture is pressed on the side of pressing plate, so that pressing plate is pressed on the connecting rod, on the work top that is pressed on clamp base that connecting rod just is fixed like this, add man-hour need to carrying out the hole to the connecting rod workpiece after clamping, these anchor clamps are turned and are fixed on the workbench, carry out hole processing according to the position of through hole on the clamp base.This clamp structure is simple, and is easy to operate, can finish the processing of a plurality of through holes of connecting rod behind clamped one time, improved production efficiency, and the error of having avoided multiple clamping to bring has improved machining accuracy.

The specific embodiment
Further set forth structure of the present invention below in conjunction with accompanying drawing.
Shown in Fig. 1-2, a kind of tie rod holes clamp for machining, these anchor clamps comprise clamp base 1, be provided with the through hole corresponding with connecting rod through hole to be processed on the work top of clamp base 1, so that directly come connecting rod is carried out hole processing according to the position of this through hole after clamping, these anchor clamps also comprise the keeper 3 that is arranged on the clamp base 1, can be arranged on rotationally the pressing plate 2 on the clamp base 1, be arranged on the fixture 4 that pressing plate 2 can be pressed on the clamp base 1 on the connecting rod, be fixedly installed on the gag lever post 5 on this clamp base 1, keeper 3 distributes and is positioned at the two sides of this connecting rod along the length direction of connecting rod, gag lever post 5 is positioned at an end of clamp base 1 work top, when needs carry out clamping and positioning to the connecting rod workpiece, this connecting rod is placed on the work top of clamp base 1, one end of this connecting rod and the end of gag lever post 5 are inconsistent, the two sides of 3 pairs of these connecting rods of keeper form the location, rotary pressure plate 2 is pressed on this connecting rod it, at this moment fixture 4 is pressed on the side of pressing plate 2, so that pressing plate 2 is pressed on the connecting rod, on the work top that is pressed on clamp base 1 that connecting rod just is fixed like this, the position of keeper 3 is to determine according to the width of connecting rod to be processed, and the length of gag lever post 5 is to determine according to the position of first through hole of connecting rod to be processed.Add man-hour need to carrying out the hole to the connecting rod workpiece after clamping, these anchor clamps are turned and are fixed on the workbench, carry out hole processing according to the position of through hole on the clamp base 1.This clamp structure is simple, and is easy to operate, can finish the processing of a plurality of through holes of connecting rod behind clamped one time, improved production efficiency, and the error of having avoided multiple clamping to bring has improved machining accuracy.
Shown in Fig. 1-2, keeper 3 comprises locating piece, this locating piece can be pressed on the bolt on the clamp base 1, can regulate easily like this position of fixed block according to the width of workpiece to be processed, thereby the front and back horizontal direction to workpiece positions, front and back horizontal direction when the front and back horizontal direction here is finger-hole processing, the above-below direction when namely the observer is in the face of Fig. 1-2.Keeper 3 is provided with four in the present embodiment.
