Abstract

The utility model provides a quick cold cutting flying saw clamp and relates to improvement on a cold cutting flying saw clamp structure. The utility model provides the quick cold cutting flying saw clamp, which is firm in clamping, quick in action and simple in structure. The quick cold cutting flying saw clamp comprises a cylinder. The structure key points are that: the end part of a piston rod of the cylinder is connected with one end of a first connecting rod and one end of a second connecting rod respectively through a first rotating shaft; the other end of the first connecting rod is connected with one end of a first lever through a second rotating shaft; the other end of the first lever is connected with a first clamping block; the other end of the second connecting rod is connected with one end of a second lever through a third rotating shaft; the other end of the second lever is connected with a second clamping block; a first fixed rotating shaft is arranged on the first lever; and a second fixed rotating shaft is arranged on the second lever.

Description

A kind of quick cold cut flying saw anchor clamps

Technical field

the utility model relates to the improvement of cold cut flying saw clamp structure.

Background technology

No matter the anchor clamps of present domestic cold cut flying saw (comprise and surging with pneumatic) adopt unidirectional or two-way clamping mode, and general oil cylinder or the cylinder Direct Action Types of adopting did not both just have reinforcement and self-locking property without Direct Action Type more yet.And for the life-span of improving the cold cut saw blade guarantees that cut quality necessarily requires anchor clamps that pipe fitting is clamped firmly, so cold cut saw cramp tool all adopts hydraulic clamp basically.But hydraulic clamp and action of releasing are relatively slow, and this has just influenced the use of cold cut saw on high speed tubulation line.

Summary of the invention

the utility model is exactly to the problems referred to above, provide a kind of clamping firmly, be swift in motion and quick cold cut flying saw anchor clamps simple in structure.

are for realizing above-mentioned purpose; The utility model adopts following technical scheme; The utility model comprises cylinder; Its structural feature cylinder piston boom end links to each other with first connecting rod one end, second connecting rod one end respectively through first rotating shaft, and the first connecting rod other end links to each other with first lever, one end through second rotating shaft, and the first lever other end links to each other with first fixture block; The second connecting rod other end links to each other with second lever, one end through the 3rd rotating shaft, and the second lever other end links to each other with second fixture block; Said first lever is provided with first fixed rotating shaft, and second lever is provided with second fixed rotating shaft.

As a kind of preferred version, said first fixture block of the utility model and second fixture block are arranged on the slideway .

as another kind of preferred version, the distance between said second rotating shaft of the utility model and first fixed rotating shaft is greater than the distance between first fixture block and first fixed rotating shaft; Distance between the 3rd rotating shaft and second fixed rotating shaft is greater than the distance between second fixture block and second fixed rotating shaft.

the utility model beneficial effect: the utility model adopts the cylinder source that is used as power, and is swift in motion, and possesses rapidity; Owing to utilized the reinforcement principle of lever to make less cylinder force produce bigger clamping force, guaranteed the fastness of clamping; Again owing to utilize the mechanics self-lock mechanism, let produce self-locking after the clamp, workpiece can't be come off voluntarily, guaranteed the reliability of clamping so again.In addition, because use pneumaticly, its manufacturing is simple relatively, and cost is also low.By the high-quality of above advantage assurance cold cut, in the life-span of also having improved saw blade widely simultaneously, saved the sawing cost.

Description of drawings

further specify the utility model below in conjunction with the accompanying drawing and the specific embodiment.The utility model protection domain not only is confined to the statement of following content.

Fig. 1 is the utility model structural representation.

Among figure, 1 is that cylinder, 2 is that second connecting rod, 3 is that the 3rd rotating shaft, 4 is that second lever, 5 is that second fixed rotating shaft, 6 is that slideway, 7 is that second fixture block, 8 is that first fixture block, 9 is that first fixed rotating shaft, 10 is that first lever, 11 is that second rotating shaft, 12 is that first connecting rod, 13 is that first rotating shaft, 14 is cylinder piston rod.

The specific embodiment

are as shown in the figure; The utility model comprises cylinder 1; Cylinder piston rod 14 ends link to each other with first connecting rod 12 1 ends, second connecting rod 2 one ends respectively through first rotating shaft 13; First connecting rod 12 other ends link to each other with first lever, 10 1 ends through second rotating shaft 11, and first lever, 10 other ends link to each other with first fixture block 8; Second connecting rod 2 other ends link to each other with second lever, 4 one ends through the 3rd rotating shaft 3, and second lever, 4 other ends link to each other with second fixture block 7; Said first lever 10 is provided with first fixed rotating shaft, 9, the second levers 4 and is provided with second fixed rotating shaft 5.

when first connecting rod 12 and first lever 10, second connecting rod 2 and second lever 4 during near 90 degree angles, the utility model produces self-locking.Cylinder 1 piston rod 14 has produced boosting function with first connecting rod 12, second connecting rod 2 formed acute angles (greater than 45 degree).

said first fixture block 8 and second fixture block 7 are arranged on the slideway 6; Be convenient to moving of fixture block.

Distance between said second rotating shaft 11 and first fixed rotating shaft 9 is greater than the distance between first fixture block 8 and first fixed rotating shaft 9; Distance between the 3rd rotating shaft 3 and second fixed rotating shaft 5 is greater than the distance between second fixture block 7 and second fixed rotating shaft 5.Through lever principle, the amplification that makes first lever 10, second lever 4 have power strengthens the reinforcement effect, and clamping has high reliability.

are below in conjunction with course of action of description of drawings the utility model: when cylinder piston rod 14 moves upward along the diagram arrows; Drive first connecting rod 12, second connecting rod 2 and promote first lever 10, second lever 4 around first fixed rotating shaft 9,5 swings of second fixed rotating shaft, then first fixture block 8, second fixture block 7 do to clamp action along slideway 6 relative motions; Otherwise when cylinder piston rod 14 moved downward along the arrow rightabout, the action of pine folder was done in first fixture block 8,7 opposing motions of second fixture block.

it is understandable that; More than about the specific descriptions of the utility model; Only be used to the utility model is described and be not to be subject to the described technical scheme of the utility model embodiment; Those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model, to reach identical technique effect; As long as satisfy the use needs, all within the protection domain of the utility model.
