[0003] During the welding process of the ball - headed pipe, defects such as pores, slag inclusions, and cracks may occur. If these defects are not dealt with in time, they will affect the strength and sealing performance of the weld.

Detailed implementation manners

[0044] The following will detail the implementation manners of the present application in conjunction with the accompanying drawings and embodiments, so as to fully understand how the present application uses technical means to solve technical problems and achieve the realization process of technical effects and implement accordingly.

[0045] As Figure 1 and Figure 2 shown, the ball head pipe end grinding structure provided in this embodiment includes a support structure 2 for supporting the ball head body 1. The support structure 2 includes a base 201, a support rod 202 welded and installed on the upper surface of the base 201, and a support cylinder 203 detachably installed on the outer surface of the support rod 202; As Figure 1As shown, the outer shape of the support cylinder 203 is conical, and a collection groove 2031 is provided inside it. The outer shape of the support cylinder 203 being conical not only facilitates the placement and positioning of the ball head body 1, but also provides stable supporting force to prevent the ball head body 1 from shaking or displacing during the grinding process. A discharge hole 2032 and a perforation communicating with the collection groove 2031 are provided inside the support cylinder 203. The ball head body 1 is placed at the top of the support cylinder 203. The support rod 202 is hollow inside.

[0046] To fix the ball head body 1, as Figure 3 shown, a fixing mechanism 3 for fixing the ball head body 1 is installed above the support structure 2. The fixing mechanism 3 includes an installation cylinder 301 fixedly installed at the top of the support rod 202, a bidirectional lead screw 303 rotatably installed inside the installation cylinder 301, a sliding seat 304 threadedly connected to the outside of the bidirectional lead screw 303, a clamping plate 306 provided on the outer surface, and a push arm 305 hinged between the sliding seat 304 and the clamping plate 306. An adjustment shaft 302 connected to the bottom end of the bidirectional lead screw 303 is rotatably installed on the upper surface of the base 201; wherein, the inside of the installation cylinder 301 is hollow, and a sliding opening is provided inside the installation cylinder 301. The bottom end of the bidirectional lead screw 303 is connected to the inner bottom wall of the installation cylinder 301 through a bearing. The adjustment shaft 302 penetrates through the inside of the support rod 202 and the support cylinder 203. By rotating the bidirectional lead screw 303, the two sliding seats 304 can be driven to move in opposite or relative directions inside the installation cylinder 301. Since the threads on the bidirectional lead screw 303 are arranged in opposite directions, when the bidirectional lead screw 303 rotates, the two sliding seats 304 will move towards the middle or both sides simultaneously, thereby realizing the clamping or loosening of the ball head body 1, and the push arm 305 connects the sliding seat 304 and the clamping plate 306. When the sliding seat 304 moves, the push arm 305 will drive the clamping plate 306 to move accordingly, thereby realizing the fixation of the ball head body 1. This design makes the fixing process fast and stable, and can ensure that the ball head body 1 will not shake or displace during the grinding process.

[0047] Specifically, the number of clamping plates 306 and sliding seats 304 is two each. The two clamping plates 306 are symmetrically arranged left and right, and the two sliding seats 304 are symmetrically arranged up and down. The number of pushing arms 305 is four, and the four pushing arms 305 are symmetrically arranged and extend to the outside of the mounting cylinder 301 through sliding openings. Since the number of clamping plates 306 and sliding seats 304 is two each, and the two clamping plates 306 are symmetrically arranged left and right, and the two sliding seats 304 are symmetrically arranged up and down, the fixing mechanism 3 can adapt to ball head bodies 1 of different sizes and shapes. By adjusting the positions of the clamping plates 306 and sliding seats 304, effective fixation of ball head bodies 1 of various specifications can be achieved. The threads on the bidirectional lead screw 303 are arranged in opposite directions. A positioning block is provided on the outer surface of the adjusting shaft 302, which can be inserted into the base 201 after the ball head body 1 is fixed to achieve fixation. A limiting guide rod for guiding the two sliding seats 304 is provided inside the mounting cylinder 301.

[0048] In this embodiment, as Figure 1 , Figure 3 , Figure 4 - Figure 12 shown, a grinding structure 4 and a lubricating mechanism 5 for processing the ball head body 1 are installed on the fixing mechanism 3.

[0049] As Figure 1 , Figure 5 - Figure 7 shown, the grinding structure 4 includes a mounting shell 401 and a mounting frame 403 that are slidably connected, a grinding block 402 disposed on one side of the mounting shell 401 close to the ball head body 1, and an elastic telescopic member 404 fixedly installed on one side of the mounting frame 403 and used to move the mounting shell 401; the shape of the grinding block 402 is adapted to the outer surface of the ball head body 1. The shape of the grinding block 402 is adapted to the outer surface of the ball head body 1, which improves the adaptability of the grinding structure 4 to the ball head body 1 and makes the polishing effect more uniform and consistent. The inside of the mounting shell 401 is hollow and has a telescopic hole 4011 opened therein. The outer shape of the mounting frame 403 is L-shaped, and a guide rail 405 for guiding the mounting shell 401 is fixedly installed on the upper surface of the mounting frame 403. The mounting shell 401 is slidably connected to the guide rail 405. Among them, as Figure 3 and Figure 12As shown, an annular guide groove 2033 is provided on the outer surface of the top end of the support cylinder 203. A guide member 406 that is in rolling fit with the guide groove 2033 is fixedly installed at the bottom end of the mounting shell 401. The guide member 406 is composed of a telescopic rod 4061 and a roller 4062. A first extrusion guide seat 20331 and a second extrusion guide seat 20332 are arranged in the guide groove 2033. The mounting shell 401 is in rolling fit with the guide groove 2033 at the top end of the support cylinder 203 through the guide member 406 (composed of a telescopic rod 4061 and a roller 4062). This design not only enables the mounting shell 401 to move stably along the guide groove 2033, but also reduces the friction and resistance during the movement. At the same time, the design of the roller 4062 also helps to maintain the smoothness during the polishing process and avoids uneven polishing caused by shaking or vibration.

[0050] In addition, an elastic telescopic member 404 is fixedly installed on one side of the mounting frame 403 for moving the mounting shell 401. This design enables the polishing block to flexibly adjust its position according to needs to adapt to ball head bodies 1 of different sizes and shapes. At the same time, the telescopic property of the telescopic rod 4061 also increases the flexibility during the polishing process, enabling the grinding block 402 to closely fit the surface of the ball head body 1 and improving the polishing quality.

[0051] Specifically, one side of the telescopic rod 4061 is bolt-fixed to the outer surface of the bottom end of the mounting shell 401. The roller 4062 is rotatably installed on the other side of the telescopic rod 4061. The first extrusion guide seat 20331 and the second extrusion guide seat 20332 are symmetrically arranged on the front and rear sides of the guide groove 2033. The outer shapes of the first extrusion guide seat 20331 and the second extrusion guide seat 20332 are semi-circular arcs, and their separated ends are connected. The concave shapes inside the first extrusion guide seat 20331 and the second extrusion guide seat 20332 are of different depths.

[0052] Such as Figure 1 、 Figure 5 - Figure 11As shown in the figure, the lubrication mechanism 5 includes a pump body 501 and an oil tank 504 fixedly installed on the upper surface of the mounting frame 403, a connecting pipe 503 fixedly installed inside the mounting shell 401, and an opening and closing structure 505 disposed on the side of the grinding block 402 close to the mounting shell 401 and slidably engaged with the connecting pipe 503. An oil delivery pipe 502 is fixedly connected between the pump body 501 and the connecting pipe 503; the opening and closing structure 505 includes a docking pipe 5051 fixedly connected to the side of the grinding block 402 close to the mounting shell 401 and an elastic member fixedly installed at the other end of the docking pipe 5051. A chute 5052 and a through hole 5053 are formed in the docking pipe 5051. The oil outlet end of the connecting pipe 503 extends into the chute 5052 and is communicated with the through hole 5053 by the deformation of the elastic member. An oil delivery hole 5054 communicated with the through hole 5053 is formed in the docking pipe 5051, and an oil outlet hole 506 is formed inside the grinding block 402; as Figure 7 shown, an oil delivery channel communicated with the oil outlet hole 506 and the oil delivery hole 5054 is provided inside the grinding block 402, and the mounting shell 401 is slidably sleeved on the outer surface of the mounting frame 403. The docking pipe 5051 extends into the mounting shell 401 through the telescopic hole 4011.

[0053] Specifically, as Figure 10 and Figure 11 shown, the elastic member includes two connecting blocks 5055, an elastic telescopic pipe 5056 fixedly installed between the two connecting blocks 5055, and a return spring 5057. The return spring 5057 surrounds the outside of the elastic telescopic pipe 5056. As Figure 1 shown, the pump body 501 is composed of a pump housing 5011 and two rotors 5013. A pump chamber 5012 adapted to the two rotors 5013 is formed in the pump housing 5011. The two rotors 5013 are rotatably installed in the pump chamber 5012 in a relative cooperative manner. An oil suction pipe is fixedly connected between the side of the pump housing 5011 away from the oil delivery pipe 502 and the oil tank 504. The adaptability between the grinding block 402 and the outer surface of the ball head body 1 ensures the uniformity of the polishing effect. By the expansion and contraction of the elastic telescopic member 404, the size when the connecting pipe 503 is docked with the through hole 5053 can be adjusted, so that the oil control function can be achieved, avoiding excessive lubrication and causing waste of lubricating oil, and achieving the effect of energy saving. The lubrication mechanism 5 transports the lubricating oil from the oil tank 504 to the connecting pipe 503 through the pump body 501, then enters the oil delivery channel inside the grinding block 402 through the opening and closing structure 505, and finally is evenly sprayed on the surface of the ball head body 1 through the oil delivery hole 5054. This design not only reduces the friction and heat during the polishing process, but also improves the polishing efficiency and surface quality. The pump body 501 is a rotor pump. A synchronous structure can also be installed between the two rotors 5013.

[0054] In addition, the elastic telescopic member 404 can be set to an electrically adjustable mode and can be used according to requirements, such as pressure adjustment, to increase the grinding pressure of the grinding block 402. At the same time, the oil delivery efficiency can also be regulated to achieve the linkage between the grinding pressure and the oil delivery.

[0055] Such as Figure 1 , Figure 5 - Figure 7 As shown in the figure, a transmission structure 6 connected to the pump body 501 is installed on the mounting frame 403. The transmission structure 6 includes a biaxial motor 601, a docking shaft 602 fixedly installed on the upper surface of the mounting cylinder 301 and penetrating through the inside of the mounting frame 403, and a gear member 603 installed between the biaxial motor 601 and the docking shaft 602. One output shaft of the biaxial motor 601 away from the gear member 603 is fixedly connected to one of the rotors 5013. Through the cooperation of the biaxial motor 601, the docking shaft 602 and the gear member 603, the transmission structure 6 realizes the driving of the pump body 501. This design not only has a compact structure, reduces the floor area, but also improves the transmission efficiency. At the same time, the use of the biaxial motor 601 also reduces the energy consumption and cost. The connection between the docking shaft 602 and the mounting cylinder 301 and the meshing transmission of the gear member 603 ensure the stability and reliability of the transmission. The bearing installation of the docking shaft 602 on the mounting frame 403 further improves the flexibility and durability of the transmission. The bottom end of the docking shaft 602 is fixed to the upper surface of the mounting cylinder 301. The gear member 603 is composed of two meshing gears, and the two gears are respectively fixedly installed on the top end of the docking shaft 602 and the other output shaft of the biaxial motor 601. The mounting frame 403 is installed on the outer surface of the docking shaft 602 by bearings.

[0056] It should be noted that the docking shaft 602 has two sections. One section is fixed to the upper surface of the mounting cylinder 301, and the other section is fixed to the gear. The upper docking shaft 602 is fixed to the lower docking shaft 602, so that when the biaxial motor 601 drives the gear member 603, it will drive the mounting frame 403 to make a circular motion around the ball head body 1.

[0057] Such as Figure 1 - Figure 12 As shown in the figure, the principle of the ball head pipe end grinding structure provided in this embodiment is as follows:

[0058] When the present invention is in use, first move the grinding block 402 to deform the elastic telescopic member 404. Then, place the ball head body 1 outside the fixing mechanism 3, support the ball head body 1 through the support cylinder 203. Next, drive the bidirectional lead screw 303 to rotate through the adjusting shaft 302, so that the two clamping plates 306 expand outwards to hold the ball head body 1 for fixation. Loosen the grinding block 402 to make it fit with the outer surface of the ball head body 1. At this time, the roller 4062 extends into the guide groove 2033, and drive the grinding block 402 through the transmission cooperation of the double-shaft motor 601 and the gear member 603, so that it moves around the circumference of the rotating ball head body 1 to achieve grinding. At the same time, make the lubricating mechanism 5 work through the transmission structure 6. The relative movement of the two rotors 5013 in the pump housing 5011 changes the working volume, so as to realize the transportation of the liquid, and transport the lubricating oil to be stored in the communicating pipe 503. When the grinding block 402 works, use the roller 4062 to roll in the first extrusion guide seat 20331 and the second extrusion guide seat 20332 with different depths to push the installation shell 401. At this time, the communicating pipe 503 moves in the chute 5052 and is displaced to communicate with the through hole 5053, so as to transport the lubricating oil into the docking pipe 5051. The lubricating oil enters the oil delivery channel in the grinding block 402 along the oil delivery hole 5054 and is finally discharged from the oil outlet hole 506 to realize the lubrication of the ball head body 1.
