Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following instance for illustration of the present invention, but is not used for limiting the scope of the invention.
Embodiment 1:
As shown in Figures 1 to 6, logical nitrogen copper pipe jig of the present invention, comprising: base 1, support bar 2, gripper shoe 5, parallels 6, tracheae 3 and pipe clamp support 4, base 1 is cast by steel, and support bar 2 is the sleeve pipe of hollow, and sleeve pipe is processed by steel pipe.The bottom of support bar 2 is fixed on base 1, and gripper shoe 5 is arranged on the top of support bar 2; The steel plate that gripper shoe 5 adopts 12mm thick processes, and machines to carry out round and smooth process to each corner angle afterwards, and the shape of preferred gripper shoe 5 is discoid, and gripper shoe 5 is provided with the pore 51 that two penetrate the plate face of gripper shoe 5.One end of tracheae 3 is connected with pore 51, and the other end of tracheae 3 is connected with outside air feed equipment.Concrete, tracheae 3 is provided with two bronchuses, 9, two bronchuses 9 and is connected with two pores 51 respectively.Bronchus 9 reaches the upper face of gripper shoe 5 through pore 51 from the below of gripper shoe 5, the mouth of pipe of preferred bronchus 9 is a little more than the plate face of gripper shoe 5, and the part using bronchus 9 to stretch out, can position installation to parallels 6.Tracheae 3 is provided with valve 7, and the present embodiment valve 7 is arranged on two bronchuses 9, controls the break-make of bronchus 9 respectively.It should be noted that, tracheae also can be multiple, are connected respectively by multiple tracheae with outside air feed equipment.One end of pipe clamp support 4 is fixedly mounted on below gripper shoe 5, and the other end is connected with tracheae 3, and tracheae 3 is suspended on below gripper shoe 5 by pipe clamp support 4.Parallels 6 adopts 20mm steel plate to process, and machines to carry out round and smooth process to each corner angle afterwards.Parallels 6 is provided with two through holes 61, and parallels 6 is placed in gripper shoe 5, and through hole 61 is corresponding with pore 51 is communicated with.The through hole 61 of parallels 6 is provided with a connecting portion, and the part being convenient to pass with tracheae 3 gripper shoe 5 is connected, and effectively prevents nitrogen from flowing out from the gap between parallels 6 and gripper shoe 5, saves gas.
Preferably, one of them in two through holes 61 is provided with out splice going splice 10.Out splice going splice 10 can rotational angle, is adapted to the needs of welding by the angle rotating out splice going splice 10.Preferred out splice going splice adopts flexible pipe to make, can random rotational angle, to adapt to the demand that copper pipe welds.
Further, this jig also comprises rotating shaft 12 and the lockable mechanism 8 for locking rotating shaft, and one end of rotating shaft 12 is fixed on the lower face of gripper shoe 5, and the other end inserts in support bar 2, and with support bar 2 matched in clearance, make gripper shoe 5 be arranged on the top of support bar 2.By matched in clearance, rotating shaft can move up and down along the axis of support bar 2, also can rotate around support bar 2.Lockable mechanism 8 is located on support bar 2.Concrete, lockable mechanism 8 comprises knob 81 and bolt 82, and knob 81 is fixedly connected with bolt 82, and the bar wall of support bar 2 is provided with a screwed hole, and bolt 82 is arranged in screwed hole.When needing the height regulating gripper shoe 5, first turning knob 81, loosering a bolt 82, regulate the height of gripper shoe 5, then tight a bolt 82, make the top of bolt 82 compress rotating shaft 12, the movement of locking rotating shaft 12.The height of gripper shoe 5 and angle are distinguished adjustable, make the adaptability of jig stronger, easy to use.
Further, this jig also comprises one but is not limited to the vice 11 of, and vice 11 is arranged on above gripper shoe 5.Gripper shoe 5 is provided with multiple vice installing hole, selects quantity and the position of installing vice 11 by vice installing hole, as the supplemental support of copper pipe when being convenient to weld.
When welding, first turning knob 81, bolt 82 of back-outing, gripper shoe 5 being adjusted to height and the angle of needs, then turn knob 81, be screwed into bolt 82, locking rotating shaft 12.Parallels 6 is placed in gripper shoe 5, and the through hole 61 of parallels 6 is connected with pore 51, after to-be-welded pieces places relevant position, corresponding valve 7 is opened, starts welding, after welding job completes, valve 7 is closed, taken down to be placed in water with clamp by the parallels 6 of use and be placed on fixation district after cooling, tracheae 3 and outside air feed equipment are disconnected, welding terminates.Structure of the present invention is simple, can the height of Reasonable adjustment gripper shoe, and the installation of parallels is simple, convenient, and particularly tracheae is provided with valve, conveniently can control the opening and closing of nitrogen conveying, reduces logical nitrogen support staff, reduces manpower, improve efficiency of construction.
