Description

Technical Field

[0001] The utility model relates to the technical field of bent pipe clamping, in particular to a bent pipe processing clamping piece. Background Art

[0002] The pipe bending clamps are mainly used to fix the pipes to be processed during the pipe bending process to ensure the stability of the pipes during the processing and prevent the pipes from moving or rotating, which may cause errors in the processing accuracy. The clamps are used to fix the pipes to ensure the processing quality and accuracy. The clamps are designed to ensure the stability of the pipes during the pipe bending process to improve the processing quality and efficiency.

[0003] Most of the existing pipe bending processing clamps use a chuck with the same radius as the pipe fitting. There are two chucks, which are respectively arranged on both sides of the clamp. The clamp drives the two chucks to tighten each other to clamp the pipe fitting to complete the fixation of the pipe fitting. However, most of the existing chucks are connected to the clamp with bolts. However, when replacing pipe fittings of other specifications, it is necessary to replace the matching chuck, and the bolts need to be disassembled to remove the chuck from the clamp. When installing the matching chuck, it is also necessary to re-adjust the position so that the two chucks are relatively aligned, which is very time-consuming and reduces production efficiency. To this end, we provide a pipe bending processing clamp to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: a pipe bending processing clamp, including a base plate 1, two guide rails 2 are fixedly connected to the upper surface of the base plate 1, two sliders 3 are slidably connected to the outer surfaces of the two guide rails 2, and the two sliders 3 are symmetrical, and the inner sides of the two sliders 3 are provided with slide grooves 4, and the inner sides of the two slide grooves 4 are slidably connected with chucks 5, the sliders 3 have a sliding function through the guide rails 2, and the guide rails 2 can also increase the stability of the sliders 3 when sliding, and the chucks 5 are driven to move their positions by sliding the sliders 3 to clamp and fix or release the clamping of the pipe fittings.

[0026] The inner wall of the slider 3 is slidably connected with a pressure plate 6, one side of the pressure plate 6 is in contact with the outer surface of the chuck 5, one side of the pressure plate 6 is fixedly connected with a guide rod 9, the outer surface of the guide rod 9 is slidably connected to the inner side of the slider 3, and the outer side of the guide rod 9 is sleeved with a spring 2 10, one end of the spring 2 10 is fixedly connected to the inner wall of the slider 3, and the other end of the spring 2 10 is fixedly connected to one side of the pressure plate 6. When the pressure plate 6 slides up and down, in order to maintain the balance of the pressure plate 6, the spring 2 10 is arranged at both ends of the pressure plate 6, so that the spring 2 10 is compressed when the pressure plate 6 slides upward, and when the pressure plate 6 slides downward, the spring 2 10 is compressed. The two sides of the pressure plate 6 provide elastic driving force to make the pressure plate 6 slide downward in parallel and contact with the chuck 5. The other side of the pressure plate 6 is threadedly connected with a locking bolt 7. The outer surface of the locking bolt 7 is rotatably connected to the inner side of the slider 3. The slider 3 can be connected to the chuck 5 through the slide groove 4. The pressure plate 6 is pushed to slide by rotating the locking bolt 7. After sliding, the pressure plate 6 contacts with the chuck 5 to limit the movement of the chuck 5. When the chuck 5 needs to be replaced, the locking bolt 7 is rotated in the opposite direction to drive the pressure plate 6 to slide, thereby releasing the fixed restriction on the chuck 5, and then the chuck 5 is taken out of the slide groove 4 and replaced with the chuck 5 of the required specifications.

[0027] A positioning mechanism 8 is provided on the outside of the locking bolt 7, and the positioning mechanism 8 can increase the stability of the pressure plate 6, so that the pressure plate 6 is always in contact with the chuck 5, and the stability of the pressure head is increased. The positioning mechanism 8 includes a sleeve 801, one side of the sleeve 801 is fixedly connected to one side of the slider 3, the inner wall of the sleeve 801 is slidably connected with a sleeve 802, and the end of the sleeve 802 located outside the sleeve 801 is fixedly connected with a chuck 1 803, and the outer surface of the locking bolt 7 is fixedly connected with a chuck 2 804, and the outer surface of the chuck 2 804 is in sliding contact with the outer surface of the chuck 1 803, and the teeth on the chuck 1 803 and the chuck 2 804 have an inclined angle, so that the chuck 2 804 can push the chuck 1 803 to move downward when the chuck 2 804 rotates, and the sleeve 801 can maintain the stability of the sleeve 802 when it slides. The groove on the inner side of the sleeve 801 cooperates with the track on the sleeve 802 to prevent the chuck 2 804 from pushing the sleeve 802 downward through the chuck 1 803 when rotating, causing the sleeve 802 to rotate and causing the chuck 1 803 to lose its positioning support for the chuck 2 804. The inner wall of the sleeve 802 is fixedly connected with a spring 1 805, and the other end of the spring 1 805 is fixedly connected to the inner bottom wall of the sleeve 801. Through the elastic support of the spring 1 805, an upward elastic driving force is provided for the sleeve 802. The sleeve 802 can push the chuck 1 803 to always contact with the chuck 2 804. In the absence of an external force pushing the locking bolt 7, the locking bolt 7 will not rotate, thereby increasing the stability of the locking bolt 7, so that the locking bolt 7 can provide a stable supporting force for the pressure plate 6.

[0028] A base 11 is fixedly connected to the upper surface of the bottom plate 1, and a forward and reverse screw 12 is rotatably connected to the inner side of the base 11. The threaded section of the forward and reverse screw 12 is connected to the inner thread of the slider 3. The slider 3 is driven to move by rotating the forward and reverse screw 12, and the slider 3 can drive the chuck 5 to move its position. A motor 13 is fixedly installed on one side of the base 11, and the output shaft of the motor 13 is fixedly connected to one end of the forward and reverse screw 12. The rotation of the motor 13 provides power for the rotation of the forward and reverse screw 12.

[0029] A slide 14 is fixedly connected to the upper surface of the base plate 1, and a frame 15 is slidably connected to the inner side of the slide 14. A plurality of rollers 16 are rotatably connected to the inner side of the frame 15, and the plurality of rollers 16 are arranged in an equidistant array. After the pipe is placed on the roller 16, the roller 16 has a rolling function, which can push the pipe to move its position, reduce the friction between the pipe and the pipe during movement, and increase the smoothness of the surface of the pipe. The rolling function of the roller 16 makes it easier to move the pipe. The slide 14 can increase the stability of the frame 15, making the frame 15 more stable when supporting the rotation of the roller 16.

[0030] Working principle: when the chuck 5 needs to be replaced, first turn the locking bolt 7. After the locking bolt 7 is rotated, it drives the pressure plate 6 to slide upwards. After the pressure plate 6 slides upwards, it breaks away from the contact with the chuck 5, and the chuck 5 is taken out of the slide slot 4. Then, the chuck 5 of the required specification is put into the slide slot 4. While turning the locking bolt 7, the locking bolt 7 drives the chuck 2 804 to rotate. When the chuck 2 804 rotates, it pushes the chuck 1 803 to move downward. The chuck 1 803 pushes the sleeve 802 to slide inside the sleeve 801. At the same time, the sleeve 802 compresses the spring 1 805. After the locking bolt 7 stops rotating, the spring 1 805 pushes the sleeve 802 to slide outside the sleeve 801. The sleeve 802 pushes the chuck 1 803 to contact with the chuck 2 804 in a dislocated manner, thereby limiting the rotation of the chuck 2 804 and fixing the locking chuck 5. Conversely, the operation is similar.
