Pipe docking device

The present invention relates to a pipe docking device, and more particularly to a docking device for fixing two pipe materials for welding.

The pipelines in the general engineering configuration will change the length or direction in a timely manner. The staff will weld and combine the two pipes with a pair of joint devices to improve the possibility of leakage caused by the sockets. Please refer to the first. As shown in FIG. 2 and FIG. 2, the docking device 1 has a body 10, and a first clamping member 11 and a second clamping member 12 are disposed on opposite sides of the housing 10, and the first clamping member 11 and the second member are provided. The clamping member 12 is respectively provided with a locking component 13 such as a hexagonal rotating rod for clamping and locking the tubular member T, and the second clamping member 12 is slidably slidable on the base 10, the first clamping member 11 and the first A rack 14 is disposed between the two clamps 12, and the rack 14 is fixedly connected to the second clamp 12. The adjustment knob 15 is disposed on the side of the first clamp 11 by the adjustment knob 15 A clamp 11 engages with the rack 14, and the second clamp 12 connected to the rack 14 is displaced as the adjustment knob 15 is rotated left and right.

The docking device 1 is used to clamp the two tubular members T to the first clamp member 11 and the second clamp member 12 respectively. The adjustment knob 15 adjusts the displacement of the second clamp member 12 so that the opposite ends of the tubular members T are close to each other. The ends of the tubes T are heated and melted by a welding unit or a hot melt unit, and then the joints T are consolidated after being cooled; however, when the tubes T are locked, The locking elements 13 need to be rotationally locked by the tool, and the second clamping member 12 cannot be locked with the seat body 10, and when the welding is easy, the sliding displacement occurs, and the tube parts T are displaced by the eccentricity of the interface to cause heat. Uneven, and the docking device 1 has a slight collision and a lack of tilting forward or backward due to the problem of the center of gravity.

In view of the above, the manufacturer has proposed the Republic of China Patent No. 511581, as shown in FIG. 3, which mentions that a thermoplastic pipe connector 2 includes a body 20 disposed on the body 20. a clamping unit 21, such as a driving unit 22 of the screw, the clamping unit 21 has a left movable seat 211 and a right movable seat 212, and the left and right movable seats 211, 212 are respectively for holding the two to be welded The end portion of the tube member T, and the driving unit 22 can drive the left and right movable seats 211, 212 to be relatively horizontally displaced, and adjust a thermal resistance element 241 of a fuse unit 24 through a control unit 23, by thermal resistance The element 241 is heated to a suitable temperature to melt the ends of the tubes T, and the melted portions T of the tubes T are pressed against each other; however, the clamping unit of the thermoplastic tube connecting machine 2 The 21 series is a horizontal displacement clamping, which is not easy to be correspondingly positioned when the tubular members T are clamped, so that the tubular members T are offset from the center of the core when the alignment is engaged, and a gap is generated, and the thermoplastic tubular connector 2 is set in groups. , making it impossible to apply to a variety of differences Construction using a fixed position.

In view of this, the creator has further derived and combined with years of experience in related businesses to propose a pipe docking device to overcome the shortcomings of the prior art.

The creation of the pipe is not easy to be positioned and the interface displacement is easy to occur when the pipe is clamped, which causes the pipe to deviate from the center of the circle when the pipe joint is engaged. Therefore, the present invention provides a pipe docking device to avoid pipe displacement during welding. The adjacent ends of the two pipes after the butting are welded and firmly joined, so as to facilitate the operation and fixation.

The purpose of this creation and solving its technical problems are achieved by the following technical solutions. According to the present invention, a pipe docking device is provided. The docking device includes a body, a first clamping device disposed above one end of the body, and a second spacer disposed above the other end of the body and slidably displaceable on the body. a first clamping device, the first clamping device and the second clamping device respectively have a first clamping device for clamping one end of the adjacent two pipes to be welded; and accordingly, the first clamping device The upper displacement knob is engaged with the rack between the first and second clamping devices, and the displacement knob is used to cooperate with the rack to synchronize the horizontal displacement of the second clamping device and adjust to an appropriate distance, and on the second clamping device A fixing knob is arranged to fix the second clamping device, and the clamping device is different from the conventional one, so that the corresponding clamping device must be matched to position and the interface displacement is not generated, and the displacement of the pipe can be prevented when the welding is prevented. Fixed positioning effect.

With the above technical solution, the present invention has the following advantages over the prior art:

1. The first clamping device is disposed above the two ends of the body and spaced apart from each other, and a second clamping device slidably displaceable on the body, and a first through the first and second clamping devices respectively With the second fixing member, it is easy to loosen and tighten the force of the implementation, and the convenience of locking the tube is more convenient.
2. The invention adds a fixing knob to the second fixing seat, which can fix the position of the second fixing seat which is sliding displacement, avoids the displacement of the pipe during welding, and is convenient for operation and fixation.
3. The creation adds a detachable base under the body to prevent the two pipes from tipping during welding, and the joint displacement of the welding does not occur.
