Abstract
The invention relates to a screw-on machine with a jaw plate body convenient to dismount. The screw-on machine comprises a main wrench and a back-up wrench. Three jaw plate components distributed in an annular array manner are arranged in the main wrench and the back-up wrench. The jaw plate components comprise a fixed body and dismountable bodies. The main wrench and the back-up wrench are provided with the fixed body. The fixed body is provided with a clamping rail, each dismountable body is provided with a clamping groove, and the clamping rail is in clamped connection with the clamping grooves. The screw-on machine has the beneficial effects that the screw-on machine only needs to machine the dismountable bodies 4 of different specifications, only one fixed body needs to be machined, and therefore the materials for machining the jaw plate components are saved; and an original integrated jaw plate component is divided into two parts to be assembled, so that the dismountable bodies 4 are relatively light, and dismounting and mounting are convenient.
Description
Technical field
The present invention relates to pipe production device, relate in particular to a kind of screw-on machine with convenient assembling jaw body.
Background technology
Screw-on machine is called again thread screw on and-off machine, is a kind of to unloading the stubborn equipment that connects of box cupling on coaxial bar, pipe and hoop class part. In the collection transportation of oil, to oil pipeline require high. The stubborn moment of torsion deficiency that connects of the junction of gas thread easily causes connection loosening, crude oil leakage, and the stubborn excessive stress that easily causes junction of moment of torsion that connects of the junction of gas thread is concentrated, thereby makes pipeline produce slight crack. Whether the stubborn moment of torsion that connects for testing conduit is in normal range (NR) in the another kind of purposes of producing screw-on machine in the enterprise of petroleum pipeline. And qualifiedly tighten rear pipeline and carry out not damaged test experience, whether testing conduit can reach the on-the-spot instructions for use of recovering the oil. In the process of actual production, due to the difference of the bore of pipeline, when can making to test the pipeline of different bores, need the jaw body of changing-over clamping pipe, because existing jaw body is very heavy, therefore to change jaw body very inconvenient. And because jaw body is processed by iron and steel, therefore need the heavy jaw body of processing more specification in order to using, thereby caused the waste of materials.
Summary of the invention
The deficiency that the present invention overcomes background technology provides the screw-on machine with convenient assembling jaw body, purpose of design: one, this device has been saved the materials of processing jaw parts. Two, these jaw parts are convenient to dismounting.
The invention provides following technical proposals: with the screw-on machine of convenient assembling jaw body, comprise main pincers, back-up tong. In described main pincers, back-up tong, be provided with the jaw parts that three circular array distribute, described jaw parts comprise fixed body, dismounting body, and described main pincers, back-up tong are provided with described fixed body. Described fixed body is provided with card rail, and described dismounting body is provided with draw-in groove, described card rail and described draw-in groove clamping. Described draw-in groove is dovetail groove.
Beneficial effect of the present invention is: its effect is that the jaw parts of original entirety are divided into two parts assembling. Because dismounting body 4 is comparatively light, the stubborn pipeline that connects different bore specifications need to be changed frock and only dismounting body 4 need to be taken off along card rail 5, draw-in groove 6 simultaneously, can complete dismounting. When installation, be also will dismantle body 4 and fixed body 3 clampings along card rail 5, draw-in groove 6. One, this device only need to be processed the dismounting body 4 of different size, and fixed body only need be processed single. Thereby the materials of processing jaw parts are saved. Two, the jaw parts of original entirety are divided into two parts assembling and have caused this dismounting body 4 relatively light, thereby be convenient to dismounting.

Fig. 2 be in Fig. 1 A to view.
Fig. 3 is the front view of jaw parts annexation of the present invention.
Fig. 4 is the left view of Fig. 3.
Schematic diagram when Fig. 5 is described fixed body 3 and dismounting body 4 released state.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the invention will be further described.
In Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5: main pincers 1, back-up tong 2, fixed body 3, dismounting body 4, card rail 5, draw-in groove 6.
With the screw-on machine of convenient assembling jaw body, comprise main pincers 1, back-up tong 2. Screw-on machine is relatively to rotate after respectively two duct members being implemented to clamp by main pincers 1, back-up tong 2, tightens. Numerical control screw-on machine also possesses torque test device. The situation of change of torsion in termination process is twisted in observation that can be real-time. Qualified the twisting of pipeline connect.
In described main pincers 1, back-up tong 2, be provided with the jaw parts that three circular array distribute, described jaw parts are clamping part. Adopt and conventionally adopt the jaw parts clamping of three circular array distributions and the periphery of steel pipe, implement fixing.
Described jaw parts comprise fixed body 3, dismounting body 4, and described main pincers 1, back-up tong 2 are provided with described fixed body 3, and described fixed body 3 is provided with card rail 5, and described dismounting body 4 is provided with draw-in groove 6, described card rail 5 and described draw-in groove 6 clampings. Described draw-in groove 6 is dovetail groove. Its effect is that the jaw parts of original entirety are divided into two, and dismounting body 4 is comparatively light, and the stubborn pipeline that connects different bore specifications need to be changed frock and only dismounting body 4 need to be taken off along card rail 5, draw-in groove 6 simultaneously, can complete dismounting. While installation so, be also will dismantle body 4 and fixed body 3 clampings along card rail 5, draw-in groove 6. Spacing in the increase of the both sides of card rail 5, draw-in groove 6 after clamping, to prevent fixed body 3 and dismounting body 4 accidental separation.
Claims (2)
1. with the screw-on machine of convenient assembling jaw body, comprise main pincers (1), back-up tong (2), it is characterized in that, in described main pincers (1), back-up tong (2), be provided with the jaw parts that three circular array distribute, described jaw parts comprise fixed body (3), dismounting body (4), described main pincers (1), back-up tong (2) are provided with described fixed body (3), described fixed body (3) is provided with card rail (5), described dismounting body (4) is provided with draw-in groove (6), described card rail (5) and described draw-in groove (6) clamping.
