[0002] In industrial production, cast iron flange pipe joints are a common connection method, and the defects of cast iron flange pipe joints during grinding are mainly the following:

[0003] 1. The high hardness of cast iron makes the grinding process difficult. Even with high-power electric tools and abrasives, it takes a long time and high-intensity grinding to achieve the ideal surface finish.

[0004] 2. Since the sealing requirements of the joints are relatively high, when grinding the joints, if they are polished manually, a certain fatigue strength will be generated, which will easily cause the grinding machine to vibrate unstably, thus causing the surface of the cast iron flange pipe joint to be uneven, resulting in insufficient sealing when connected to the pipeline.

[0005] Therefore, it is necessary to provide an automated processing machine for manufacturing cast iron flange pipe joints to solve the above technical problems. Summary of the invention

[0006] The purpose of the present invention is to provide an automated processing machine for manufacturing cast iron flange pipe joints to solve the problem raised in the above background technology that due to the relatively high sealing requirements of the joints, when grinding the joints, if they are polished manually, a certain fatigue strength will be generated, which will easily lead to the problem of unstable shaking of the grinder, thus causing the surface of the cast iron flange pipe joint to be uneven, resulting in the problem that the sealing is not good enough when it is connected to the pipeline. The technical solution of the present invention is aimed at the technical problem that the existing technical solutions are too single, and provides a solution that is significantly different from the existing technology.

[0013] In a further embodiment, a piston is installed at the end of the electric telescopic rod, and the outer side of the piston and the inner wall of the oil cylinder form a sealed sliding structure.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figure 1-5An embodiment of the present invention is as follows: an automated processing machine for manufacturing cast iron flange pipe joints, comprising a support seat 1, a rotating drum 2 is arranged on the support seat 1, and a rotating groove 3 is opened inside one side of the support seat 1, a rotating rod 4 is rotatably connected inside the rotating groove 3, a driving shaft 5 is arranged on one side above the support seat 1, and an oil cylinder 6 is connected to the inner side of the driving shaft 5, and an electric telescopic rod 7 is connected to one side of the oil cylinder 6; a second driven wheel 401 is installed on the outer side of the rotating rod 4, and a grinding roller 402 is also installed on the outer side of the rotating rod 4; a clamping mechanism 8 for clamping cast iron flange pipe joints of different diameters is arranged on the outer side of the oil cylinder 6.

[0028] For examples, see Figure 1 and Figure 3-5 , oil inlet holes 601 are opened at equal intervals on the outside of the oil cylinder 6, a piston 701 is installed at the end of the electric telescopic rod 7, and the outer side of the piston 701 and the inner wall of the oil cylinder 6 form a sealed sliding structure, the clamping mechanism 8 includes a telescopic sleeve 801 installed on the inside of the oil cylinder 6, and the end of the telescopic sleeve 801 is connected to a clamping plate 802, and the telescopic sleeve 801 is connected to the oil inlet hole 601;

[0029] First, select the appropriate grinding roller 402 according to the size specifications of the cast iron flange pipe joint, then pass several grinding rollers 402 through the groove, and insert them into the outer side of the step from the left side of the cast iron flange pipe joint in sequence, and then insert the grinding roller 402 and the pipe joint from the right end of the rotating rod 4 and the driving shaft 5. After each step on the outer side of the pipe joint is adapted to the outer groove of the grinding roller 402, the pipe joint needs to be clamped and fixed. The specific operation steps are described as follows:

[0030] By starting the electric telescopic rod 7 through the control button, the piston 701 is driven to move to the right inside the oil cylinder 6. At this time, the oil inside the oil cylinder 6 is also squeezed to the right at the same time. During the squeezing process, the oil will enter the inside of the telescopic sleeve 801 from each oil inlet hole 601, so that several telescopic sleeves 801 extend outward and drive the clamping plate 802 to extend outward until the clamping plate 802 can stably clamp and tighten the inside of the pipe joint, thereby completing the clamping and fixing of the pipe joint.

[0031] Example 2 Please refer to Figure 1-2 , which is different from Example 1 in that: a slide rail 201 is provided on the outer side of the rotating drum 2, and the rotating drum 2 forms a sliding structure with the rotating drum 2 through the slide rail 201, the rotating rod 4 is square-shaped, and the outer side of the rotating rod 4 is connected to the second driven wheel 401 and the grinding roller 402, the lower side of the second driven wheel 401 is meshed with the first driven wheel 403, and the outer side of the driving shaft 5 is installed with a driving wheel 501, and the outer side of the driving wheel 501 is meshed with the outer side of the second driven wheel 401;

[0032] After the pipe joint is clamped and fixed, the servo motor on the left side of the support seat 1 can be started by the control button to drive the driving shaft 5, the driving wheel 501, the clamping mechanism 8 and the outer pipe joint to rotate simultaneously. When the driving wheel 501 rotates, it can also drive the first driven wheel 403 to rotate, thereby driving the second driven wheel 401 to rotate, and then drive the rotating rod 4 and the grinding roller 402 to rotate in the same direction as the pipe joint under the cooperation of the rotating groove 3, so as to efficiently grind the steps on the outer side of the pipe joint. By utilizing the effect of the grinding roller 402 and the pipe joint rotating in the same direction, the grinding efficiency of the cast iron flange joint can be further improved, and the surface of the pipe joint step can be polished smoother and with higher flatness, so that the sealing of the pipe joint during installation can be effectively guaranteed;

[0033] In summary, when it comes to flange pipe joints of different specifications, the step spacing dimensions on their outer sides will also be different. The above structure can be applicable to flange pipes of different diameters and steps with different spacings on their outer sides, and can also greatly improve the grinding efficiency, smoothness and flatness of the flange pipes, thereby improving the sealing of the cast iron flange pipe joint installation.

[0034] Working principle: Figure 1-5 As shown, first select the appropriate grinding roller 402 according to the size specification of the cast iron flange pipe joint, then pass several grinding rollers 402 through the groove part, and successively clamp them into the outer side of the step from the left side of the cast iron flange pipe joint, and then insert the grinding roller 402 and the pipe joint from the right end of the rotating rod 4 and the driving shaft 5. After each step on the outer side of the pipe joint is adapted to the outer groove of the grinding roller 402, the pipe joint needs to be clamped and fixed. The specific operation steps are described as follows:

[0035] The electric telescopic rod 7 is activated by the control button to drive the piston 701 to move to the right inside the oil cylinder 6. At this time, the oil inside the oil cylinder 6 is also squeezed to the right. During the squeezing process, the oil enters the inside of the telescopic sleeve 801 from each oil inlet hole 601, so that several telescopic sleeves 801 extend outward and drive the clamping plate 802 to extend outward until the clamping plate 802 can stably clamp and tighten the inside of the pipe joint, thereby completing the clamping and fixing of the pipe joint.

[0036] After the pipe joint is clamped and fixed, the servo motor on the left side of the support seat 1 can be started by the control button to drive the driving shaft 5, the driving wheel 501, the clamping mechanism 8 and the outer pipe joint to rotate simultaneously. When the driving wheel 501 rotates, it can also drive the first driven wheel 403 to rotate, thereby driving the second driven wheel 401 to rotate, and then drive the rotating rod 4 and the grinding roller 402 to rotate in the same direction as the pipe joint under the cooperation of the rotating groove 3, so as to efficiently grind the steps on the outer side of the pipe joint. By utilizing the effect of the grinding roller 402 and the pipe joint rotating in the same direction, the grinding efficiency of the cast iron flange joint can be further improved, and the surface of the pipe joint step can be polished smoother and with higher flatness, so that the sealing of the pipe joint during installation can be effectively guaranteed;

[0037] In summary, when it comes to flange pipe joints of different specifications, the step spacing dimensions on their outer sides will also be different. The above structure can be applicable to flange pipes of different diameters and steps with different spacings on their outer sides, and can also greatly improve the grinding efficiency, smoothness and flatness of the flange pipes, thereby improving the sealing of the cast iron flange pipe joint installation.
