[0028] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0030] Example 1

[0031] Automobile pipeline bending equipment, consisting of a clamping component 5, a supporting component, a torsion component 4 and an adjustment component;

[0032] The clamping assembly 5 is composed as follows:

[0033] like Figure 1 、 Figure 2 、 Figure 4 、 Figure 6As shown, a cylindrical shell 51 is fixed to the surface of the vertical plate frame 11, and a slot 52 is provided on the end surface of the shell 51. The inner end of the slot 52 extends inwardly to form an annular portion. An annular groove 53 is provided inside the shell 51, and one end of the annular groove 53 coincides with the outer side of the annular portion. A plurality of clamping plates 55 are arranged around the annular groove 53, and one end of the clamping plate 55 passes through the annular portion. A piston ring 54 is adapted to slide in the annular groove 53. The surface of the piston ring 54 has an arc-shaped protrusion for resisting the raised end of the clamping plate 55. A spring is connected between the piston ring 54 and the shell 51 for pulling the piston ring 54 away from the clamping plate 55.

[0034] The air supply assembly includes an air pump 7, which is installed on the other side of the plate frame 11. The exhaust end of the air pump 7 is connected to a tee pipe 71. One branch end of the tee pipe 71 is connected to the annular groove 53 through a pipeline, and the other branch end of the tee pipe 71 is connected to the external environment through a solenoid valve 72.

[0035] The air pump 7 and the solenoid valve 72 are controlled by the controller programming;

[0036] Insert one end of the metal tube into the slot 52, and fit the end of the metal tube into the annular portion. Then, turn on the air pump 7 to supply air. The air enters the annular groove 53, and the piston ring 54 overcomes the elastic force and slides forward under the action of the air pressure. The piston ring 54 presses the clamping plate 55 to rotate, so that the clamping plate 55 clamps the end of the metal tube together.

[0037] When the metal tube is released, the electromagnetic valve 72 is controlled to open, the gas in the ring groove 53 is discharged, the piston ring 54 is reset, all the clamping plates 55 lose the squeezing force, and then the metal tube is taken out from the slot 52.

[0038] The support components are as follows:

[0039] like Figure 5 、 Figure 6 As shown, the airbag tube 81 is made of elastic rubber. One end of the airbag tube 81 is fixed at the center of the inner end surface of the slot 52. The other end of the airbag tube 81 is fixedly connected to a reduced diameter end head 82. The end of the reduced diameter end head 82 is spherical. A plurality of steel balls 8 are arranged and sleeved on the outside of the airbag tube 81. Adjacent steel balls 8 are in contact. The size of the reduced diameter end head 82 is smaller than that of the steel balls 8. The reduced diameter end head 82 prevents the steel balls 8 from slipping off. A through opening 56 is provided inside the slot 52 and passes through the annular groove 53. The airbag tube 81 is connected to the annular groove 53 through the through opening 56.

[0040] Before fixing the metal tube, the air pump 7 first introduces gas at a certain pressure into the ring groove 53. At this time, the piston ring 54 only overcomes a certain spring force and does not contact the clamping plate 55. The gas at this time is introduced into the airbag tube 81 through the opening 56, increasing the air pressure in the airbag tube 81 and hardening it, which is used to support the linear distribution of the steel balls 8. The metal tube is sleeved around the steel balls 8 at one end of the reduced diameter end 82 and then inserted into the slot 52, so that the steel balls 8 contact the inner wall of the metal tube. Then, a second air supply and pressure increase causes the piston ring 54 to squeeze the clamping plate 55 to clamp the metal tube.

[0041] The torsion assembly 4 is composed as follows:

[0042] like Figure 7 As shown, the fixed wheel 2 is rotatably mounted on the surface of the base 41, one end of the rotating arm 42 rotates coaxially with the fixed wheel 2, the moving wheel 3 rotates on the other end of the rotating arm 42, and the rotating arm 42 swings to make the moving wheel 3 rotate around the fixed wheel 2. One end of the rotating arm 42 connected to the fixed wheel 2 is coaxially fixed with a worm gear 43, and a second motor 45 is fixedly mounted on the surface of the base 41. The output shaft of the second motor 45 is fixed with a worm 44, and the worm gear 43 is meshed with the worm 44;

[0043] The edges of the fixed wheel 2 and the moving wheel 3 are both arc-shaped depressions that fit the metal tube. The metal tube passes through the fixed wheel 2 and the moving wheel 3, and then the metal tube is clamped and fixed. The second motor 45 is turned on to drive the worm 44 to rotate. The worm gear 43 drives the rotating arm 42 and the moving wheel 3 to rotate around the fixed wheel 2 through meshing transmission. The moving wheel 3 squeezes the metal tube and bends it around the fixed wheel 2. The airbag tube 81 inside the metal tube is also bent. The arranged steel balls 8 support the bent part of the metal tube so that it will not deform.

[0044] After the metal tube is bent, the airbag tube 81 needs to be deflated, and then the arranged steel balls 8 and the airbag tube 81 are pulled out from the metal tube.

[0045] The adjustment components are as follows:

[0046] like Figure 1 、 Figure 2 As shown, the linear assembly includes a stage 1, a screw 13 is rotatably provided on the surface of the stage 1, and the screw 13 extends along the axial direction of the metal tube. A first motor 12 is installed at the end of the stage 1, and the output shaft of the first motor 12 is connected to the screw 13, and the external thread of the screw 13 is connected to the moving block 14;

[0047] like Figure 3As shown, the rotating assembly includes a ring frame 6, a moving block 14 is fixed to the bottom of the ring frame 6, the ring frame 6 is coaxially arranged with the metal tube, a straight slider is symmetrically fixed to the bottom of the ring frame 6, two linear rails are symmetrically fixed to the surface of the stage 1, the straight sliders are slidably connected to the linear rails, so that the ring frame 6 can move on the surface of the stage 1 along the axial direction of the metal tube, two sets of circular tracks are set on the inner wall of the ring frame 6, an arc-shaped slider is fixed to the surface of the base frame 41, and the arc-shaped slider is slidably connected to the annular track so that the base frame 41 can slide in an annular manner around the inner wall of the ring frame 6, the base frame 41 is fixed with a gear ring 61, and the gear ring 61 is concentrically distributed on the inner side of the ring frame 6, the third motor 62 is fixedly mounted on the surface of the ring frame 6, and the output shaft of the third motor 62 is connected to the gear ring 61 through gear meshing transmission;

[0048] When the bending direction of the metal tube needs to be adjusted, the third motor 62 is turned on to drive the gear ring 61 to drive the base frame 41 to rotate, so that the fixed wheel 2 and the moving wheel 3 rotate around the axis of the metal tube. After the angle is determined, the metal tube is squeezed and bent by the fixed wheel 2 and the moving wheel 3.

[0049] When it is necessary to adjust different parts of the metal tube for bending, the first motor 12 is turned on to drive the lead screw 13 to rotate, so that the moving block 14 drives the ring frame 6 to move linearly along the axis of the metal tube, and adjusts the fixed wheel 2 and the moving wheel 3 to different positions of the metal tube;

[0050] When performing multi-point bending on the metal tube, first bend the end of the metal tube away from the clamping assembly 5, and then perform multi-point bending on the metal tube close to the clamping assembly 5 in turn. After each bending, the moving wheel 3 needs to rotate to the initial position of the fixed wheel 2 to avoid the bending part hindering the movement of the fixed wheel 2 and the moving wheel 3.
