Detailed ways

The utility model will be more clearly and completely described below by means of a preferred embodiment in conjunction with the accompanying drawings, but the utility model is not limited to the scope of the described embodiment.

As shown in Fig. 1 and Fig. 2, it is a steel pipe fast clamping tool disclosed by the utility model, which includes a clamping platform 1, and clamps for clamping steel pipes 2 are arranged along the length direction of the clamping platform, and the clamps include The clamp base 3 and the clamping frame fixed on the clamp base 3 are detachably connected between the clamp base 3 and the clamping platform 1 , the clamping frame has a support part 4 and a locking part 5 , and the locking part 5 is located above the support part 4 , the support part 4 is symmetrically provided with an adjustment arm 6 for supporting the steel pipe, and the clamping end of the adjustment arm 6 faces the inside of the clamping frame; one end of the locking part 5 is rotationally connected with the support part 4, and the other end is through The locking mechanism 7 is fixed, and the locking arm 8 is arranged at the position where the locking part 4 faces the symmetrical center of the two adjusting arms. The locking arm 8 is vertically arranged. The tight arm 8 compresses the steel pipe 2 on the clamping end of the regulating arm 6 .

Before clamping the steel pipe, the locking part 5 is in the open state. When the steel pipe 2 is placed on the adjusting arm 6, the locking part 5 is rotated so that the locking part 5 and the supporting part 4 form a closed clamping frame. 7 for locking, the locking arm 8 is pressed on the upper end of the steel pipe 2, and the pipeline is clamped and fixed by the cooperation of the locking arm 8 and the two adjusting arms 6. For steel pipes of the same specification or similar size, there is no need to adjust the adjusting arm 6 position, the steel pipe can be fixed and loosened directly by rotating the locking part, which is convenient to operate, reduces the time of the clamping process, and improves efficiency.

Specifically, in order to stabilize the structure of the supporting part, the supporting part 4 of the utility model adopts a square shape, the bottom of the supporting part 4 is fixed on the clamp base 3, and the adjusting arm 6 is installed on the support arms 9 on both sides of the supporting part 4 , the adjustment arm 6 is slidingly connected with the support arm 9 along the clamping direction, the adjustment arm 6 includes a sliding frame 10, the middle part of the sliding frame 10 is provided with a sliding hole for slidingly matching with the support arm 9, and the sliding frame 10 is located inside the clamping frame One end of the sliding frame 10 is provided with a chuck, and the end of the sliding frame 10 away from the clamping frame is provided with an adjusting screw 11, and the adjusting screw 11 passes through the end of the sliding frame 10 and is screwed with the support arm 9 along the clamping direction, and the adjusting screw 11 is in the clamping direction. A push plate 12 for pushing the sliding frame 10 to slide is fixedly sleeved on the shaft.

The bottom of the square shape can provide enough supporting force, and the slide frame set by sliding can change the position of the chuck. When steel pipes of different specifications need to be clamped and fixed, the position of the chuck can be changed by turning the adjusting screw 11. In order to meet the clamping requirements of steel pipes with different diameters, assuming that the diameter of the steel pipe is reduced, the existing chuck position cannot effectively support the steel pipe, and it is necessary to move the sliding frame 10 to the inner side of the clamping frame, and the two sliding frames 10 Keep the same moving distance, reduce the distance between the two chuck brackets, so that the steel pipe can still fall between the chucks. When the diameter of the steel pipe becomes larger, although the existing chuck position can support the steel pipe, it will cause the support The force is mainly concentrated on the lower part of the steel pipe, and the force is not balanced enough. Therefore, the sliding frame needs to be retracted so that the force distribution of the steel pipe will not be too concentrated and the stability will be better.

The collet of the utility model can adopt the form of the existing pipeline collet, but this type is not convenient for loading and adjusting the pipeline, so the utility model also improves the type of the collet, specifically, the collet The roller 13 made of elastic material is used to avoid damage to the steel pipe wall caused by rigid contact. The roller 13 is connected to the end of the sliding frame 10 through the roller frame 14. The roller frame 14 rotates with the sliding frame 10 in the direction of the axis of the adjusting screw. To connect, when the steel pipe is installed, turn the roller frame 14 so that the rolling direction of the roller 13 is consistent with the axial direction of the steel pipe 2, and the installation of the steel pipe 2 is assisted by the roller 13.

If the second chuck 17 also adopts a roller structure, then even if the steel pipe is clamped, it will still rotate. This situation is suitable for welding or butt jointing of steel pipes, but when cutting or drilling, if the steel pipe has the ability to rotate degree of freedom, then it will have an impact on the processing process. Therefore, in the embodiment of the utility model, the second chuck 17 is designed as an arc-shaped plate structure. When the steel pipe is clamped, the steel pipe will not rotate in the circumferential direction.

At the same time, in order to be able to adapt to the clamping and fixing of steel pipes of different lengths, and to facilitate the adjustment of the position and distance of the clamps, a detachable connection structure is adopted between the clamp base of the utility model and the clamping platform 1, specifically, the utility model The clamping platform 1 is provided with a number of fixing holes 18 along the length direction, and the clamping base 3 and the clamping platform 1 are locked and fixed by bolts penetrating into the fixing holes.

When the weight of the steel pipe is not heavy, it is not necessary to turn the roller frame 14, but directly put the steel pipe on the roller, turn the locking part 5, and tighten the locking bolt 19 , turn the second adjusting screw 16 to drive the second chuck 17 to move down to clamp the steel pipe. When replacing the steel pipe, the locking arm 8 can be moved up to penetrate the steel pipe, and the locking mechanism can also be released , turn the locking part 5 to open, and put the steel pipe in. For a large number of steel pipes of the same specification, the locking mechanism 7 can be designed as a structure that can be quickly locked and opened. After the steel pipe is clamped for the first time, no It is necessary to adjust the positions of the locking arm 8 and the adjusting arm 6, and perform quick clamping directly by opening and closing the locking mechanism 7.
