The machining of the pipe fitting in the application can refer to cutting, milling, polishing, grinding and the like of the outer surface of the pipe fitting after the pipe fitting is positioned.
A pipe positioning device as shown in fig. 1 to 6, comprising: a support bar 10; the positioning assembly 20 is sleeved on the support rod, the positioning assembly 20 can extend into the pipe fitting, the positioning assembly 20 comprises a fixed member 21 and at least two movable members 22 arranged along the circumferential direction of the fixed member 21, the fixed member 21 is provided with a slideway 23 along the radial direction of the support rod 10, and the movable members 22 are in sliding fit with the slideway 23; the driving member 30 is sleeved on the supporting rod, the driving member 30 is connected with the fixing member 21, a driving portion 31 is arranged on one side of the driving member 30 facing the moving member 22, and when the driving member 30 rotates around the supporting rod 10, the driving portion 31 drives the moving member 22 to move along the slideway 23 so that the moving member 22 has a first state of tightly supporting the pipe fitting from the inside of the pipe fitting and a second state of separating from the inner wall of the pipe fitting.
The utility model provides a pipe fitting positioner, locating component 20 can stretch into inside the pipe fitting in order to realize the pipe fitting location from the pipe fitting is inside, through the radial direction removal of driving piece 30 drive moving part 22 for the bracing piece, moving part 22 has the first state of propping tight pipe fitting from the pipe fitting is inside and breaks away from the second state of pipe fitting inner wall, with the installation location or the dismantlement of realization positioner and pipe fitting, moreover, the steam generator is simple in operation, and help increasing the effective processing area of pipe fitting surface, and to thin-walled pipe spare, can avoid causing the pipe to warp easily when pressing from both sides from the pipe fitting outside to it, and can adapt to the pipe fitting of broad pipe diameter scope, and has good adaptability.
Wherein, movable part 22 and slide 23 sliding fit can realize that mounting 21 carries out radial spacing to movable part 22, simultaneously, driving piece 30 is connected with mounting 21 and can realizes carrying out axial spacing to movable part 22, from this, driving piece 30, mounting 21 and movable part 22 interconnect each other, restrict each other and make positioner overall structure compact, and movable part 22 is difficult for taking off from the bracing piece pine, help the locating component to stretch into the pipe fitting fast, conveniently in order to implement the pipe fitting location to improve work efficiency.
Specifically, the driving member 30 can rotate around the supporting rod 10, for example, an external thread can be disposed on the supporting rod 10, and correspondingly, an internal thread for matching rotation is disposed in the driving member 30, and further, the driving member 30 is connected to the fixing member 21, and in an implementation, the driving member 30 and the fixing member 21 can be connected through an internal bearing, so that the driving member 30 can rotate relative to the fixing member 21 when rotating around the supporting rod 10. Further, the fixed member 21 provides a sliding track 23 for the movable member 22 to move, and the driving portion 31 can drive the movable member 22 to move along the sliding track 23 when the driving member 30 rotates around the support rod 10.
From this, the process that positioner of this application fixes a position the pipe fitting or pipe fitting is dismantled from positioner can be as follows: when the movable element 22 is located at the first position of the slideway 23, the pipe to be processed is sleeved on the positioning element 20 from the opening thereof, the first position of the slideway 23 means that the movable element 22 is located at one end of the slideway 23 closest to the support rod 10, and the maximum radial dimension of the positioning element 20 at this time meets the requirement of being smaller than the inner diameter dimension of the pipe, so that the positioning element 20 can smoothly extend into the pipe; the driving member 30 is then operated to drive the movable members 22 to move along the sliding ways 23 in a direction away from the support rod 10, when the movable members 22 move to the second position of the sliding ways 23, the plurality of movable members 22 support the pipe from the inner side of the pipe, the second position of the sliding ways 23 means that the movable members 22 are located at the end of the sliding ways 23 away from the support rod 10, at this time, the movable members 22 contact the inner wall of the pipe and support the pipe, and the positioning device positions the pipe. When the pipe fitting needs to be disassembled, the driving member 30 is operated to rotate around the supporting rod 10 in the opposite direction, the movable member 22 moves from the second position of the slideway 23 to the first position, and when the movable member 22 moves to the first position, the movable member 22 is separated from the inner wall of the pipe, and at this time, the pipe fitting can be disassembled from the positioning assembly 20. It will be appreciated that when the moveable member 22 moves to the second position of the ramp 23, the moveable member 22 has a first state and when the moveable member 22 moves to the first position of the ramp 23, the moveable member 22 has a second state. It should be noted that, for pipe fittings with different pipe diameters, there is a difference between the second position where the movable element 22 moves to the slideway 23, so as to meet the requirement that the movable element 22 reaches the first state to tightly support the pipe fitting from the inside of the pipe fitting.

As a preferred embodiment of this application, the driving piece 30 winds the bracing piece 10 can be followed when rotatory the bracing piece 10 axial displacement, be equipped with the measuring tape on the bracing piece 10, the driving piece 30 for the predetermined numerical range that the measuring tape removed can with the moving part 22 is followed the predetermined stroke of slide 23 motion matches, and the driving piece 30 for the different predetermined numerical range that the measuring tape removed can adapt to the pipe fitting of different pipe diameters.
The relationship between the movable member 22 and the pipe fitting can be determined by observing the axial movement distance of the driving member 30 positioned outside the pipe fitting, so that the pipe deformation easily caused by excessive movement of the movable member 22 can be prevented, and the positioning accuracy can be improved; the driving member 30 can adapt to the pipe fittings of different pipe diameters relative to different preset value ranges of the movement of the measuring scale, so that the positioning device can position the pipe fittings of more pipe diameters intuitively, and the positioning efficiency is improved through the identification effect of the measuring scale.
During specific implementation, the preset value range of the movement of the driving member 30 relative to the measuring tape may be matched with the preset stroke of the moving member 22 moving from the first position to the second position along the slideway 23, for example, for a pipe fitting with a preset pipe diameter, when the moving member 22 moves from the first position to the second position along the slideway 23, the corresponding driving member 30 moves from the zero scale of the measuring tape to a scale corresponding to a certain value along the axial direction, so that it can be determined whether the moving member 22 reaches the first state of tightly supporting the pipe fitting by observing the moving distance of the driving member 30, the pipe fitting positioning degree is easy to grasp, and a user does not need to worry about deformation when the pipe fitting is excessively stressed due to excessive rotation when operating the driving member 30.
