Detailed description of the invention
With reference to accompanying drawing, pipe part turning attachment embodiment of the present invention is described further.
A kind of pipe part turning attachment, comprise mount pad 1, mount pad 1 is connected with jaw 2, jaw 2 is curved, jaw 2 side is provided with inner arc surface 22, opposite side is provided with exterior arc surface 21, the radian of exterior arc surface 21 is greater than the radian of inner arc surface 22, namely middle part to the two ends of jaw 2 are thickening gradually, when fixing pipe part, pipe part can be clamped by inner arc surface 22, during clamping, inner arc surface 22 outer circumference surface that is complete and pipe part is fitted, and the radian of jaw 2 is generally greater than 90 ° and be less than or equal to 120 °, the jaw 2 of 120 ° can be used, the outer circumference surface of pipe part is fully abutted by the inner arc surface 22 of three jaws 2, made fixing comparatively stable by larger contact area, can to the pipe part establishing another model by outer circumference surface, the outer circumference surface also by three jaws 2 fully abuts with the inner peripheral surface of pipe part, thus can fix pipe part, by the fixture arranged like this, the pipe part of two kinds of different models can be clamped, and the abundant abutting of inner arc surface 22 and exterior arc surface 21, pipe part can be made fixing firm.
Wherein, inner arc surface 22 side stretches out and forms keeper 5, keeper 5 can abut with the end face of pipe part, pipe part is played to the effect of location, and keeper 5 is also curved, fits with the end face of pipe part, fully can fix the end face of pipe part like this, prevent pipe part from rocking, keeper 5 is affixed with mount pad 1 near mount pad 1 side, can fully fix keeper 5 like this.Simultaneously, keeper 5 is locating surface away from mount pad 1 side, locating surface upwards turns down away from inner arc surface 22 side and forms location flanging 51, flanging abuts with the edge of the inwall of pipe part, play auxiliary fixing effect, by flanging and inner arc surface 22 double action, make pipe part more stable.Further, slot to make way 52 is formed between location flanging 51 and locating surface, elastic strip is connected with in slot to make way 52, by the setting of slot to make way 52, in order to place the pipe part with certain burr, facilitate the placement of pipe part end face, and elastic strip can be made up of elastomeric material, fully abutted the inwall of pipe part by the elasticity of elastic strip, fix pipe part further.
And locate the opposite side outwardly convex formation reinforcement of flanging 51 relative to locating surface, the cross section of reinforcement is circular arc, by the setting of arc surface, when locating flanging 51 and being stressed, the reinforcement of circular arc can disperse by counter stress, make the stress of locating on flanging 51 can not be too concentrated, thus ensure that location flanging 51 is less likely to occur to damage.
Exterior arc surface 21 stretches out and forms positioning step 3, and the effect of positioning step 3 is similar to keeper 5, and can fit with the end face of pipe part in the surface of positioning step 3, thus prevent rocking of pipe part further.And between positioning step 3 and exterior arc surface 21, be formed with deep-slotted chip breaker 6, the cross section semicircular in shape of deep-slotted chip breaker 6, deep-slotted chip breaker 6 reality is escape, need not lack man-hour adding, but when being processed into semicircular cross section subsequently, the effect of dissipation of ferees can be played, prevent jaw 2 stress from too concentrating and rupturing; Further, be connected with elastic component in deep-slotted chip breaker 6, elastic component protrudes deep-slotted chip breaker 6, and elastic component is that rubber is made, and the elastic component of protrusion can abut the inwall of pipe part, pipe part is abutted more stable, can also play certain cushioning effect.
Circular arc 4 is fixed in the outwardly formation of positioning step 3, fixing circular arc 4 is provided with fixing hole, mount pad 1 is provided with the through hole corresponding with fixing hole, certain booster action can be played by arranging of fixing circular arc 4, make the structural strength of jaw 2 entirety higher, situation about rupturing is less likely to occur, (being generally welded and fixed) can be fixed with mount pad 1 further by bolt by fixing circular arc 4 simultaneously, thus ensure the fastness that jaw 2 is fixing.
The above is only the preferred embodiment of the present invention, protection scope of the present invention be not only confined to above-described embodiment, and all technical schemes belonged under thinking of the present invention all belong to protection scope of the present invention.It should be pointed out that for those skilled in the art, some improvements and modifications without departing from the principles of the present invention, these improvements and modifications also should be considered as protection scope of the present invention.
