[0037] A conveying system for controlling a high-precision fixed-length cutting conveying line of precision seamless steel pipes for stabilizer bars, the conveying system comprising:

[0038] S1: Setting the required length of the seamless steel pipe 6 by means of a fixed length adjustment device;

[0039] S2: Start the driving motor 4 to drive the conveying roller 3 to rotate, thereby conveying the seamless steel pipe 6;

[0040] S3: When the seamless steel pipe 6 touches the pressure sensor on the stop head 28, the fixed-length cutting device is controlled to start, thereby cutting the seamless steel pipe 6;

[0041] S4: On the basis of S3, while the fixed-length cutting device is started, the linkage unit 17 controls the linkage pressure-bearing component 7 to hold the seamless steel pipe 6 tightly, thereby preventing the seamless steel pipe 6 from bending.

[0042] The working principle and beneficial effects of the above technical solution are as follows: when in use, the required length of the seamless steel pipe 6 is set through the fixed-length adjustment device, and then the drive motor 4 is started to drive the conveying roller 3 to rotate, so as to convey the seamless steel pipe 6. When the seamless steel pipe 6 touches the pressure sensor on the stop head 28, the drive motor 4 is controlled to be turned off and the fixed-length cutting device is started, so as to cut the seamless steel pipe 6. While the fixed-length cutting device is started, the linkage pressure-bearing component 7 is controlled by the linkage unit 17 to hold the seamless steel pipe 6 tightly, so as to prevent the seamless steel pipe 6 from bending.

[0043] Example 2

[0044] Based on Example 1, please refer to Figure 1-2 The fixed-length cutting device includes: a crank connecting rod 11, one end of the crank connecting rod 11 is fixedly sleeved with a bevel gear 2 10, and the bevel gear 2 10 is meshed with the bevel gear 1 9, the other end of the crank connecting rod 11 is movably connected to a fixed bracket 13, one end of a crank sleeve 12 is movably connected to the center of the crank connecting rod 11, the other end of the crank sleeve 12 is movably connected to the top of a reciprocating push rod 15, the bottom of the reciprocating push rod 15 movably passes through a fixed bracket 2 14 and is provided with a push head 16, and a fixed wheel 18 is fixedly connected to the push head 16.

[0045] Preferably, the two groups of fixing blocks 24 are fixedly connected to the mounting bracket 1 located on the left side, the two ends of the guide rod 20 are fixedly connected to the two groups of fixing blocks 24, the guide sleeve 19 is movably sleeved on the outer wall of the guide rod 20, the fixed end of the high-speed cutter 22 is connected to the guide sleeve 19 through the bracket plate 21, one end of the reset spring 23 is fixedly connected to the bracket plate 21, and the other end of the reset spring 23 is fixedly connected to the fixing block 24 located at the bottom.

[0046] The working principle and beneficial effects of the above technical solution are as follows: when in use, the driving motor 28 is started and drives the bevel gear 19 to rotate, and then the bevel gear 19 drives the bevel gear 210 to drive the crank connecting rod 11 to rotate. When the crank connecting rod 11 rotates, it will drive the reciprocating push rod 15 to move downward first through the crank sleeve 12, and then the push head 16 will continue to move after contacting the bracket plate 21. At this time, the guide sleeve 19 moves downward along the guide rod 20 while compressing the reset spring 23, and the high-speed cutter 22 will be pushed into the U-shaped knife groove bracket 5 while being started synchronously, so that after the seamless steel pipe 6 is cut off, the crank sleeve 12 drives the reciprocating push rod 15 to move upward for reset, and the push head 16 no longer contacts the bracket plate 21. The high-speed cutter 22 rises and resets under the push of the reset spring 23.

[0047] At the same time, the cut seamless steel pipe 6 is separated from the stop head 28, so that the pressure sensor on the stop head 28 is no longer under pressure. At this time, the high-speed cutter 22 is closed, and the drive motor 4 is started to continue to transport the seamless steel pipe 6 until it touches the pressure sensor on the stop head 28 again.

[0048] Example 3

[0049] Based on any one of Examples 1-2, please refer to Figure 2-3 The fixed-length adjustment device includes: a fixed-length bracket 25 and an adjustment bracket 33, both of which are fixedly connected to the mounting bracket 1 on the right side, and a plurality of positioning holes 26 are provided on the fixed-length bracket 25. The guide sleeve 27 is slidably connected to the front end of the adjustment bracket 33, and the connecting kit 29 is movably connected to the guide sleeve 27, and the connecting kit 29 extends downward to form a stop head 28, and a pressure sensor is installed on the side of the stop head 28 close to the seamless steel pipe 6. The connecting kit 29 extends upward to form a U-shaped groove, and the U-shaped kit 31 is connected to the positioning hole 26 through a pin 34. The first connecting rod 30 is installed in the U-shaped groove formed by the connecting kit 29 and the U-shaped kit 31, and the two ends of the first connecting rod 30 are respectively connected to the inner wall of the U-shaped groove of the connecting kit 29 and the U-shaped kit 31 through the same connecting spring 1 32.

[0050] The working principle and beneficial effects of the above technical solution are as follows: when the cutting length of the seamless steel pipe 6 needs to be changed, the operator can push the guide sleeve 27 to move along the adjustment bracket 33 after pulling out the pin 34, so as to adjust the travel distance of the seamless steel pipe 6, and then control the cutting length of the seamless steel pipe 6. When the length needs to be fine-tuned, the angle of the stop head 28 can be changed by rotating the connecting kit 29, so as to achieve the accuracy of the cutting position and cutting length adjustment of the seamless steel pipe 6. After the determination is made, the pin 34 is used to adjust the cutting length of the seamless steel pipe 6. The U-shaped kit 31 is connected to the positioning hole 26 to fix the connecting kit 29 and the guide sleeve 27 to prevent them from loosening. The first connecting rod 30 and the two sets of connecting springs 1 32 are provided to facilitate the connection of the U-shaped kit 31 with the positioning holes 26 at different positions. It should be noted that the first connecting rod 30 cannot be separated from the connecting kit 29 and the inner wall of the U-shaped groove of the U-shaped kit 31. This is done to prevent the connecting kit 29 from rotating after the pin 34 locks the U-shaped kit 31, thereby causing the cutting length to change.

[0051] Example 3

[0052] Based on any one of Examples 1-2, please refer to Figure 4-5The linkage unit 17 includes: a mounting sleeve 35, the top outer wall of the mounting sleeve 35 is connected to the fixed bracket 14 through a fixing rod 39, the piston push head 37 and the airbag 38 are both arranged in the mounting sleeve 35, and the piston push head 37 is slidably connected to the inner wall of the mounting sleeve 35, one end of the second connecting rod 36 movably extends into the mounting sleeve 35 and is fixedly connected to the piston push head 37, and the other end of the second connecting rod 36 is fixedly provided with a rope fixing member 41, the return spring 40 is sleeved on the outer wall of the second connecting rod 36, and the two ends of the return spring 40 are respectively fixedly connected to the outer wall of the mounting sleeve 35 and the rope fixing member 41, the support frame 43 is fixedly connected to the fixed bracket 14, the roller 45 is connected to the support frame 43 through the roller bracket 44, one end of the connecting rope 42 is wound around the rope fixing member 41, and the other end of the connecting rope 42 movably passes through the support frame 43 and is wound around the roller 45 and then fixedly connected to the fixed wheel 18.

[0053] Preferably, the linkage pressure-bearing assembly 7 includes: a protective shell 47, the protective shell 47 is fixedly connected to the conveying platform 2, the fixed end of the pneumatic push rod 48 is fixedly connected to the bottom of the inner wall of the protective shell 47, the output end of the pneumatic push rod 48 is fixedly provided with a support push piece 49, the pneumatic push rod 48 is connected to the airbag 38 through an air pipe, a rotating shaft 59 is movably connected to the inner wall of the protective shell 47, an avoidance groove 60 is provided on the protective shell 47, and the rotating shaft 2 60 is movably connected to the inner wall of the avoidance groove 60, one end of the telescopic rod 1 50 is movably connected to the support push piece 49, the other end of the telescopic rod 1 50 is fixedly connected to the rotating shaft 1 59, one end of the telescopic rod 2 51 is fixedly connected to the rotating shaft 1 59, the other end of the telescopic rod 2 51 is fixedly connected to the rotating shaft 2 61, one end of the third connecting rod 52 is fixedly connected to the rotating shaft 2 61, the other end of the third connecting rod 52 is fixedly connected to the steel pipe claw 53, and the steel pipe claw 53 is provided with an anti-slip pad 54 on the side close to the seamless steel pipe 6.

[0054] Preferably, two groups of fixing blocks 2 55 are fixedly connected to the top of the outer wall of the protective shell 47, two ends of the guide rod 2 62 are fixedly connected to the two groups of fixing blocks 2 55, two groups of guide sleeves 3 56 and reset spring 3 57 are all sleeved on the outer wall of the guide rod 2 62, and the guide sleeve 3 56 is movably connected to the guide rod 2 62, two ends of the reset spring 3 57 are respectively fixedly connected to the two groups of guide sleeves 3 56, one end of the fourth connecting rod 58 is movably connected to the guide sleeve 3 56, and the other end of the fourth connecting rod 58 is movably connected to the support bracket 46.

[0055] The working principle and beneficial effects of the above technical solution are as follows: when the reciprocating push rod 15 moves downward and pushes the high-speed cutter 22 to move, the push head 16 moves by pulling the connecting rope 42 through the fixed wheel 18, and the second connecting rod 36 moves outward along the inner wall of the mounting sleeve 35, thereby compressing the airbag 38 through the piston push head 37. At this time, the gas in the airbag 38 is transported to the pneumatic push rod 48 through the air pipe, thereby pushing the output end of the pneumatic push rod 48 upward to lift the supporting push piece 49, thereby making the telescopic rod 1 50 drive the rotating shaft 1 59 to rotate, and while the rotating shaft 1 59 rotates, the rotating shaft 2 61 is driven to rotate through the telescopic rod 2 51, thereby making the rotating shaft 2 61 drive the third connecting rod 52 to approach. The two sets of steel pipe claws 53 are rotated in the direction close to the seamless steel pipe 6 until the two sets of steel pipe claws 53 hold the seamless steel pipe 6 tightly. At this time, the high-speed cutter 22 just contacts with the seamless steel pipe 6 and presses down to cut. The two sets of steel pipe claws 53 are not tight at this time, which can play a tightening role when cutting the seamless steel pipe 6 again to prevent the seamless steel pipe 6 from shifting during the cutting process. Moreover, the small downward pressure generated by the high-speed cutter 22 when cutting the seamless steel pipe 6 can be transmitted to the two sets of fourth connecting rods 58 through the supporting bracket 46. At this time, the two sets of fourth connecting rods 58 push the two sets of guide sleeves three 56 to move along the third connecting rod 52 in the direction away from each other, and then disperse the downward pressure through the reset spring three 57 to prevent the seamless steel pipe 6 from deforming during cutting.

[0056] It should be noted that the downward pressure generated by cutting the seamless steel pipe 6 is not large, and the multi-link mechanism composed of the telescopic rod 1 50, the telescopic rod 2 51 and the third connecting rod 52 allows a small range of movement, so that it can fluctuate with the downward pressure generated during cutting, avoiding the deformation of the seamless steel pipe 6 during cutting due to excessive rigidity.

[0057] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
