Description

Technical Field

[0001] This utility model relates to the field of pipe grinding and welding technology, and more specifically, it relates to an automated grinding and welding integrated equipment for pipe parts. Background Technology

[0002] In the manufacturing process of tubular parts, grinding and welding are crucial steps, and their quality directly determines the final performance and service life of the tubular parts. Traditional grinding methods for tubular parts mainly rely on manual operation or direct grinding by robotic arms.

[0003] Currently, when polishing pipe fittings on the market, operators need to repeatedly polish the outer side of the fitting. Due to the limitations of manual operation, it is not only labor-intensive and inefficient, but also difficult to guarantee the uniformity and precision of polishing, resulting in inconsistent surface quality of the pipe fittings. More importantly, during manual polishing, the close contact between the operator and the pipe fitting makes it easy for the generated debris and dust to cause physical harm to the operator. In addition, the repetitive polishing action over a long period of time may also lead to occupational diseases, such as arm pain and joint damage.

[0004] While using a robotic arm for direct grinding improves efficiency and precision to some extent, the robotic arm frequently interferes with the pipe during rotary grinding due to the spatial relationship between its rotation trajectory and the pipe. This interference not only damages the robotic arm to varying degrees, affecting its lifespan and stability and increasing maintenance costs and downtime, but also causes secondary damage to the pipe, reducing its processing quality and potentially leading to its scrapping, resulting in wasted raw materials and increased production costs.

[0005] Therefore, developing an automated grinding and welding integrated equipment for pipe parts that can effectively avoid the above problems is of great practical significance. Utility Model Content

[0016] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0018] Please see Figure 1-7 The present invention provides the following technical solution: Example 1: To address the following problems in the prior art: When performing grinding operations on welded pipe fittings, if manual grinding is used, the operator needs to grind around the outside of the pipe fitting; if a robotic arm is used for grinding, the robotic arm needs to perform a rotating grinding action, and the robotic arm is prone to interference with the pipe fitting during the rotation process, which can lead to damage to the robotic arm.

[0019] The automated grinding and welding integrated equipment includes a housing 1, a first slide 2 slidably disposed on the top of the housing 1 for clamping and conveying the pipe fitting to be ground and welded, and a welding device 3 disposed on the top of the housing 1. The automated grinding and welding integrated equipment also includes a grinding adjustment mechanism 4. The grinding adjustment mechanism 4 is disposed on the top of the housing 1 and includes a bearing part 41, a rotating part 42, and a grinding part 43. The bearing part 41 is slidably disposed on the side of the housing 1 and is located on the side of the welding device 3. The rotating part 42 is rotatably disposed on the side of the bearing part 41 and is above the first slide 2. An opening for the pipe fitting to be ground and welded to pass through is opened in the middle of the rotating part 42. The grinding part 43 is slidably disposed on the side of the rotating part 42 and is used to grind the pipe fitting to be ground and welded. When the rotating part 42 rotates, it can drive the grinding part 43 to rotate synchronously.

[0020] First, the robotic arm positions the welded pipe to be ground at the center of a pair of first slides 2. Then, the first slides 2 activate and clamp the welded pipe. After clamping, the lead screw slide activates, driving the first slides 2 to move closer together. When the welded pipe is moved to the center opening of the rotating part 42, the rotating part 42 begins to rotate via the support part 41. Since the grinding part 43 is mounted on the rotating part 42, the rotating part 42 synchronously drives the grinding part 43 to rotate during its rotation, thus achieving a circular rotary grinding operation on the welded pipe.

[0021] See Figures 3-5 The grinding adjustment mechanism 4 also includes a first fixed ring 44, a first engaging ring 45, and a rotary driver 46. The first fixed ring 44 is disposed on the outside of the rotating part 42 and is fixedly connected to the end face of the rotating part 42. The first engaging ring 45 is rotatably disposed on the end face of the bearing part 41 and engages with the first fixed ring 44. The rotary driver 46 is disposed on the end face of the bearing part 41 and the output end of the rotary driver 46 is connected to the first engaging ring 45. When the rotary driver 46 is started, it can drive the first engaging ring 45 to rotate relative to the first fixed ring 44.

[0022] The end faces of the first fixed part and the rotating part 42 are welded together. In order to drive the rotating part 42 to a stable rotating state on the end face of the bearing part 41, the rotary driver 46 is first started, which in turn drives the first engagement ring 45 to rotate. When the first engagement ring 45 rotates, it can rotate relative to the engaged first fixed ring 44, thereby realizing the rotational drive of the rotating part 42 and the grinding part 43.

[0023] See Figures 5-7 The grinding adjustment mechanism 4 also includes a first rotating bearing wheel 47 and a second rotating bearing wheel 48; the first rotating bearing wheel 47 is a pair and is rotatably disposed on the side of the bearing part 41, and the pair of first rotating bearing wheels 47 are located on both sides of the rotating part 42, and the pair of first rotating bearing wheels 47 are engaged with the first fixing ring 44; the second rotating bearing wheel 48 is a pair and is rotatably disposed on the top of the bearing part 41, and the pair of second rotating bearing wheels 48 are respectively on the top of the bearing part 41 and above the first engagement ring 45, and the pair of second rotating bearing wheels 48 are engaged with the first fixing ring 44.

[0024] To ensure stable rotation of the rotating part 42, the rotating part 42 is abutted by the first engagement ring 45, the first rotating bearing wheel 47, and the second rotating bearing wheel 48, respectively, to ensure that the rotating part 42 does not tilt during rotation.

[0025] See Figures 4-6The grinding adjustment mechanism 4 also includes a first mounting part 49, a connecting part 491, and a telescopic cylinder 492. The first mounting part 49 is disposed on the end face of the rotating part 42 and is located beside the bearing part 41. A guide groove is provided on the end face of the first mounting part 49. The connecting part 491 is slidably disposed on the end face of the first mounting plate, and there is a clearance fit between the connecting part 491 and the guide groove. The telescopic cylinder 492 is disposed beside the first mounting part 49, and the output end of the telescopic cylinder 492 is connected to the connecting part 491. When the telescopic cylinder 492 is activated, it can drive the connecting part 491 to move along the first mounting part 49.

[0026] When the rotating part 42 rotates, it can drive the first mounting part 49, the connecting part 491 and the telescopic cylinder 492 to rotate synchronously.

[0027] See Figure 6 The grinding adjustment mechanism 4 also includes a rotary motor 493 and a rotating rod 494; the rotary motor 493 is disposed on the end face of the connecting part 491; the rotating rod 494 is disposed on the output end of the rotary motor 493, and the outer side of the rotating rod 494 is connected to the end face of the grinding part 43.

[0028] When the rotary motor 493 is started, the rotating rod 494 is rotated. When the rotating rod 494 rotates, it drives the grinding part 43 to rotate synchronously, thereby realizing the rotational grinding of the welded pipe fitting to be ground. When the telescopic cylinder 492 is started, the connecting part 491 and the grinding part 43 can move up and down, which can be adjusted to adapt to changes in the outer diameter of the pipe fitting.

[0029] See Figures 4-6 The grinding adjustment mechanism 4 also includes a positioning part 495, a linear guide rail 496, and a lead screw 497. The positioning part 495 is a pair and is respectively disposed on the top of the housing 1, and the pair of positioning parts 495 are located below the welding equipment 3. The linear guide rail 496 is disposed on the top of the pair of positioning parts 495, and the bottom of the bearing part 41 is slidably connected to the linear guide rail 496, so that the bearing part 41 can move on the top of the linear guide rail 496. The lead screw 497 is rotatably disposed on the side of the linear guide rail 496, and the lead screw 497 is threadedly connected to the bearing part 41. When the lead screw 497 rotates, it can drive the bearing part 41 to move along the top of the linear guide rail 496.

[0030] To prevent interference between the grinding adjustment mechanism 4 and the welding equipment 3, the pipe fitting to be ground is first clamped and transported by the first slide 2. In this state, the lead screw 497 drives the bearing part 41 to move away from the welding equipment 3 along the linear guide rail 496. At this time, the grinding part 43 and the rotating part 42 grind the joint between the two pipe fittings. After grinding, the lead screw 497 drives the bearing part 41 to move away from the welding equipment 3 along the linear guide rail 496. Then, the first slide 2 drives the clamped pipe fitting to be ground to move below the welding equipment 3. Finally, the welding equipment 3 performs the welding operation.

[0031] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
