A location ready-packaged clamp for turning of quarter bend class part, including anchor clamps body 1 and dog 2, system has

logical groove

3 and 10 lower extremes of quarter bend class part to locate logical groove 3 in anchor clamps body 1 up end middle part system, it is used for carrying out the setting element I4 of fixing a position to quarter bend class part 10 turning end to lead to be equipped with on 3 groove faces of groove, dog 2 corresponds and removable be fixed in on 1 upper end outer wall of anchor clamps body with leading to 3 positions of groove, be equipped with on dog 2 and press from both sides tight setting element II 5 of fixing along leading to 3 length direction of groove to quarter bend class part 10 under the cooperation with setting element I4, install in on 1 lateral wall of anchor clamps body and be used for fixing a position tight piece 6 of top that goes on the width direction of leading to groove 3 to quarter bend class part 10, and make the tight setting element I4, setting element II 5 and the cooperation of top tight piece 6 down to make quarter bend class part 10 press from both sides tight location treat that (ii) a

In the structure, the positioning piece I4, the stop block 2 with the positioning piece II 5 and the jacking piece 6 are respectively arranged in the through groove 3, at one end part and at the side wall of the upper end surface of the clamp body 1, so that the right-angle elbow part 10 is quickly clamped on the clamp body 1, the problem of high clamping and correcting difficulty of the right-angle elbow part 10 is solved, and the complicated clamping and correcting working steps of the right-angle elbow part 10 are simple, convenient and quick;

the positioning piece I4 is specifically a positioning pin, a unthreaded hole 7 is formed in the bottom surface of the through groove 3, the lower end of the positioning pin is in clearance fit with the unthreaded hole 7, the upper end of the positioning pin is in contact with one end of the right-angle elbow part 10, and when the length of two sides of the right-angle elbow part 10 is smaller than the distance between the unthreaded hole 7 on the left side and the stop block 2, only one unthreaded hole 7 needs to be formed in the left side of the center of the bottom surface of the through groove 3; specifically, according to the locating pin that straight elbow class part 10 lower extreme length of side adopted in logical groove 3 is the step round pin that the upper end diameter is different, and the step axle is adopted to this place, mainly be guarantee that the locating pin contacts with the lateral wall of the right elbow class part 10 corner back, the axis that the side was treated to processing by straight elbow class part 10 coincides with the axis of anchor clamps body 1, realizes the quick centering of straight elbow class part 10.

Specifically, the two unthreaded holes 7 are distributed on two sides of the center of the bottom surface of the through groove 3;

when the length of two sides of the right-angle elbow part 10 is smaller than the maximum distance between the unthreaded hole 7 far away from the side of the stop block 2 and the stop block 2, the right-angle elbow part 10 is quickly positioned and clamped on the clamp body 1 under the combined action of a positioning piece I4, a jacking piece 6 and a positioning piece II 5 which are matched in the unthreaded hole 7 far away from the side of the stop block 2; during specific operation, as shown in fig. 4, the lower end of the elbow bend part 10 is arranged in the through groove 3, the positioning piece i 4 is inserted into the through hole 7 on the left side, the side wall of the corner of the elbow bend part 10 is abutted against the positioning piece i 4, the rotary positioning piece ii 5 is abutted against the right end face of the lower end edge of the elbow bend part 10, the abutting piece 6 is screwed and abutted against the elbow bend part 10, and at the moment, the axis of the vertical edge of the elbow bend part 10 is overlapped with the axis of the clamp body 1; as shown in fig. 5, when the other end of the elbow bend part 10 is machined, the stop block 2 is detached and reversed and then installed on the left side wall of the upper end of the fixture body 1 through the bolt 9, the positioning piece i 4 is inserted into the through hole 7 on the right side, the side wall of the corner of the elbow bend part 10 is abutted against the positioning piece i 4, the rotary positioning piece ii 5 is abutted against the left end face of the lower end edge of the elbow bend part 10, the jacking piece 6 is screwed tightly against the elbow bend part 10, and the axis of the other end of the elbow bend part 10 is coincided with the axis of the fixture body 1; the structure is used for processing the right-angle elbow part 10 with different side lengths of two sides, but the two sides are used when the distance between the unthreaded hole 7 far away from the stop block 2 and the stop block 2 is large;

if the length of the two sides of the right-angled bend part 10 is the same and the diameter is the same, only the unthreaded hole 7 located on the outer side of the center of the through groove 3 needs to be processed on the through groove 3, the distance between the center of the unthreaded hole 7 and the central axis of the clamp body 1 is the same as the radius of the right-angled bend part 10, and the positioning of the two end parts of the right-angled bend part 10 can be completed without reversing the stop block 2 when the right-angled bend part is used.

In the structure, the two unthreaded holes 7 distributed on two sides of the center of the groove are formed in the bottom surface of the through groove 3, and the replacing positioning piece I4 is matched with the unthreaded holes 7 at different positions according to the side length of the elbow part 10, so that the elbow parts 10 with different side lengths are quickly clamped and positioned on the clamp body 1, the processing range of the elbow parts 10 is enlarged, and the limitation of the elbow parts 10 on the application range of the clamp is eliminated;

when one of them length of side of elbow bend class part 10 is greater than and keeps away from 2 one sides unthreaded hole 7 of dog and the maximum distance between the dog 2, elbow bend class part 10 is through increasing the gasket or increasing 2 modes of dog thickness between 1 upper end lateral wall of anchor clamps body and dog 2 by the combined action of adaptation in keeping away from 2 one side unthreaded hole 7 of dog I4, top tight 6 and setting element II 5 down quick location dress clamp on anchor clamps body 1.

The setting element II 5 specifically is positioning bolt, 2 lower extremes of dog are fixed in on the anchor clamps body 1 through bolt 9 and threaded connection stretches into logical inslot 3 and supports tightly the other end of the quarter bend class part 10 of one end and I4 contact of setting element in the positioning bolt of dog 2 upper end.

The concrete tight bolt that is in top of tight piece 6, threaded connection has and leads to groove 3 vertically tight bolt in having

breach

8 and 8 groove faces on the system on the outer wall of anchor clamps body 1, support on elbow type part 10 lower extreme outer wall in leading to groove 3 in the tight bolt tip screw in.

In the technical scheme, the clamp body 1 and the stop block 2 are made of No. 45 steel, quenching is not needed, the processing cost is low, the structure is simple, and the manufacture is convenient; the structure has the advantages of rapid part clamping, accurate positioning and high reliability; the structure is simple and practical, the working strength of an operator can be effectively reduced, the working efficiency is obviously improved, and the device has the advantages of wide application range, simplicity in manufacturing, easiness in popularization and application and good practicability.
