Description

Technical Field

[0001] This utility model relates to the technical field of burr removal equipment, and in particular to an automatic burr removal device for pipe fittings. Background Technology

[0002] Burrs inside pipe fittings refer to protrusions formed inside the pipe fitting port, usually due to the accumulation of metal or other materials during processing. These burrs may affect the sealing performance of the pipe fitting, fluid flow efficiency, and may even lead to equipment failure or damage.

[0003] Existing deburring processes, whether manual or electric, require manual intervention, which is time-consuming, labor-intensive, and inefficient. Furthermore, the grinding debris generated during the grinding process can have adverse effects on human health due to close contact with the human body. Moreover, the burrs cannot be removed after grinding and remain inside the pipe, becoming impurities. Therefore, this application proposes an automatic burr removal device for pipe fittings to solve the above problems. Utility Model Content

[0061] Two sets of clamping components 8 are provided corresponding to the limiting components 7. The two sets of clamping components 8 are symmetrically arranged on the top surface of the support frame 1 to clamp and fix the two ends of the pipe 10 downwards, so as to ensure that the pipe 10 will not move during grinding or purging.

[0062] In a preferred embodiment, the clamping assembly 8 is disposed on the support frame 1 between two sets of limiting assemblies 7, including a second U-shaped frame 81 fixedly disposed on the support frame 1, a second driving cylinder 82 fixedly disposed vertically on the top plate of the second U-shaped frame 81, and the piston rod of the second driving cylinder 82 passing vertically downward through the top plate of the second U-shaped frame 81; a clamping seat 83 is disposed on the inner side of the second U-shaped frame 81, and the transmission end of the piston rod of the second driving cylinder 82 is fixedly connected to the top surface of the clamping seat 83; the clamping seat 83 is driven to move up and down by the second driving cylinder 82.

[0063] The top plate of the second U-shaped frame 81 is symmetrically provided with second through holes on both sides of the second drive cylinder 82. The top plate of the second U-shaped frame 81 is provided with a second guide sleeve 84 in the vertical direction corresponding to the second through hole. A second guide rod 85 is provided through the second guide sleeve 84 and the corresponding second through hole. One end of the two second guide rods 85 located on the inner side of the second U-shaped frame 81 is fixedly connected to the top surface of the pressing seat 83 to improve the stability of the pressing seat 83 during the up and down lifting movement.

[0064] In a preferred embodiment, the bottom surface of the clamping seat 83 is provided with an inverted V-shaped clamping port 86 corresponding to the pipe 10, which is designed similarly to the shape of the roller and is used to limit the left and right movement of the pipe 10.

[0065] In a preferred embodiment, the distance between the two mounting brackets 2 is greater than the length of the pipe fitting 10.

[0066] In a preferred embodiment, the device further includes a photoelectric switch 9. Two sets of photoelectric switches 9 are provided on the support frame 1. The two sets of photoelectric switches 9 are respectively disposed between the pressing component 8 and the corresponding limiting component 7, and are used to monitor whether the tube 10 has moved to the bottom of the corresponding grinding component 5.

[0067] Among them, the photoelectric switch 9 is existing technology, including a transmitter and a receiver, which are structurally separated. When the beam is interrupted, a switch signal change will be generated. Typically, photoelectric switches located on the same axis can be separated by up to 50 meters.

[0068] The working principle of this utility model:

[0069] During operation, the pipe 10 is placed on the roller conveyor belt 3. The pipe 10 is moved by the rollers until the photoelectric switch 9 detects that one end of the pipe 10 has moved to the grinding component 5 at its corresponding end. The pipe 10 moves to the limiting plate 74 at the corresponding end for limiting (the initial state of the limiting plate of this end is set higher than the top surface of the support frame). The roller conveyor belt 3 stops running and the movement of the pipe 10 stops.

[0070] Then, the clamping assembly 8 is used to press the pipe fitting 10 downward. Specifically, the second drive cylinder 82 drives the corresponding clamping seat 83 to move downward until it moves to the upper surface of the pipe fitting 10 and presses the pipe fitting 10. Then, the mounting seat 73 and the limiting plate 74 at one end are lowered to the bottom of the support frame 1 under the drive of the first drive cylinder 72.

[0071] The first linear module 41, the second linear module 42, and the third linear module 43 drive the corresponding grinding component 5 to move up, down, left, and right until the corresponding grinding component 5 enters the port of the pipe fitting 10. The drive motor 51 drives the grinding brush 53 to rotate inside the port of the pipe fitting 10. Then, through the linkage of the first linear module 41, the second linear module 42, and the third linear module 43, the grinding brush 53 performs circumferential grinding inside the port of the pipe fitting 10.

[0072] After grinding, the grinding debris will remain inside the port of the pipe 10. Through the coordinated operation of the first linear module 41, the second linear module 42 and the third linear module 43, the grinding component 5 is disengaged from the port of the pipe 10. Then, the blowing component 6 at the corresponding end is inserted into the port of the pipe 10. By activating the air source equipment, the gas enters the air blower 61 through the air inlet pipe 63 and is then blown out through the air nozzle 62 to blow out the grinding debris inside the port of the pipe 10, thus achieving the purpose of blowing.

[0073] The grinding and purging process of the other end of the pipe fitting 10 is the same as above. The pipe fitting 10 is moved in the opposite direction by the roller conveyor belt 3, and the position of the pipe fitting 10 is monitored and limited by another set of photoelectric switches 9 and limit components 7. Then, it is pressed down and fixed by the pressing component 8, and ground and purged by another set of grinding components 5 and purging components 6.

[0074] The entire process is highly automated with minimal human intervention, reducing harm to the human body, resulting in high work efficiency and excellent grinding and cleaning effects.
