Description

Technical Field

[0001] This utility model relates to a longitudinal seam milling device with displacement adjustment based on tracked yaw, belonging to the technical field of weld seam milling. Background Technology

[0002] Large pipes are widely used in the construction, industrial manufacturing, municipal engineering, and energy sectors. Pipes can be classified by material, including plastic, metal, and concrete.

[0003] For large metal pipes, welding operations are required to form the pipes. The pipes are made by rolling sheet metal into a tubular structure. Welding is required at the longitudinal seams of the joints. Before welding the longitudinal seams, the joint ends are beveled. Then, the inner wall joints of the rolled pipe are welded. After the inner wall joints are welded, the outer longitudinal seams are milled to form the weld before welding. This process meets the welding quality requirements.

[0004] However, since the pipe is made by rolling sheet metal into a tube, the outer longitudinal seam may have a certain deviation or curvature due to the certain tolerance of the sheet metal itself and the deformation during the inner welding. At this time, direct linear milling will result in relative positional deviation, which may lead to deviation from the splice seam, resulting in local missing welds or incomplete welds when the pipe is finally welded. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of the prior art and to propose a longitudinal seam milling device with the ability to track and adjust displacement, which addresses the problem of milling position deviation caused by a certain positional deviation in traditional splicing longitudinal seams.

[0015] Preferably, the yaw adjustment slide is provided with two spaced-apart mounting brackets, and the spindle carrier is provided with a carrier side plate that is slidably mounted perpendicularly to each of the mounting brackets.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0032] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in the present application can be combined with each other.

[0033] This utility model provides a longitudinal slot milling device with displacement adjustment based on tracked runout, such as... Figures 1 to 6 As shown, it includes a track base 100 and a weld milling forming device 200.

[0034] like Figure 2 As shown, the weld milling forming device 200 includes a milling sliding base 1 with linear displacement slidably mounted on the track seat 100, a yaw adjustment slide 2 with yaw horizontal displacement disposed on the milling sliding base 1, and a spindle carrier 3 with lifting displacement disposed on the yaw adjustment slide 2. The yaw horizontal displacement direction of the yaw adjustment slide 2 is perpendicular to the linear displacement direction of the milling sliding base. The spindle carrier 3 is provided with a milling spindle 4 having a milling disk 40 and a visual guide part 5 located on one side of the milling direction of the milling disk 40 and facing the longitudinal seam of the pipe body. The visual guide part 5 is communicatively connected to the weld milling forming device.

[0035] Detailed implementation process and principle explanation:

[0036] The weld milling forming device 200 performs linear displacement along the track seat 100 to achieve linear milling of the weld. Depending on the weld specifications to be milled, the relative position of the milling is adjusted by the lifting displacement of the main spindle carrier 3. During the linear displacement of the yaw adjustment slide 2, the relative position of the current milling disc 40 and the spliced ​​weld is monitored by the vision guide 5, which enables the yaw adjustment slide 2 to perform corresponding position correction, meet the real-time follow-up adjustment requirements, ensure the accuracy of the weld milling position, and guarantee the welding qualification rate of the downstream pipe.

[0037] In one specific embodiment, the track base 100 is provided with two slidingly connected milled sliding bases with two spaced-apart support slide rails 110, and a passive tooth row 120 is provided on the side wall of any one of the support slide rails.

[0038] The milling sliding base 1 is provided with at least one milling linear drive source 6. The milling linear drive source 6 includes a rotary drive end 61 and a drive gear disk 62 disposed on the rotary drive end and meshing with the passive gear row.

[0039] Specifically, the rotary drive end 61 drives the drive gear disk 62 to rotate, and the drive gear disk 62 performs gear engagement transmission on the passive gear row 120, thereby driving the milling sliding base 1 to linearly displace on the support slide rail 110.

[0040] In one specific embodiment, such as Figure 2 As shown, the milling sliding base 1 is provided with milling linear drive sources 6 at both ends along the linear displacement direction.

[0041] Specifically, by designing milling linear drive sources 6 at both ends of the linear displacement direction, reliable drive control of the milling sliding base 1 can be achieved, making its linear displacement more stable and reliable, and ensuring the machining quality.

[0042] In one specific embodiment, such as Figure 2 As shown, the milling sliding base 1 is provided with two sliding mating swing adjustment slides 2 with their swing rails 11 arranged at intervals.

[0043] The milling sliding base 1 is provided with a rotary motor 12 and a swing adjustment screw 13 that is connected to the rotary motor. The bottom of the swing adjustment slide 2 is provided with a screw seat 21 that is connected to the swing adjustment screw.

[0044] Specifically, the milling sliding base 1 is slidably connected to the support slide rail 110 through the slide rail and bracket, while the yaw slide rail 11, the rotary motor 12, and the yaw adjustment screw 13 are all mounted on the slide rail and bracket.

[0045] When performing yaw displacement driving, the visual guidance unit 5 obtains the relative deviation displacement after image acquisition, and drives the yaw adjustment slide 2 to drive the corresponding deviation displacement. The image acquisition, deviation displacement calculation and control signal acquisition methods of the visual guidance unit 5 are existing technologies and will not be described in detail here.

[0046] When driving the yaw adjustment slide 2, the rotary motor 12 drives the yaw adjustment screw 13 to rotate, and the torque rotation of the screw seat 21 is converted into the yaw displacement of the yaw adjustment slide 2, thus realizing the adjustment drive.

[0047] In one specific embodiment, the rotating end of the rotary motor 12 is connected to the driving end of the yaw adjustment screw via a transmission toothed belt.

[0048] This layout is more compact, and the transmission belt can provide a certain degree of shock resistance, making its drive more reliable and stable. Of course, structures using bushing rotation transmission and gear meshing transmission are all within the scope of protection of this case.

[0049] In one specific embodiment, the yaw adjustment slide 2 is provided with two spaced-apart mounting brackets 22, and the spindle carrier 3 is provided with carrier side plates 30 that slide perpendicularly to the mounting brackets.

[0050] The arbitrary mounting frame 22 is equipped with a lifting drive source 7 that is connected to the corresponding seat side plate 30 for transmission.

[0051] The spindle carrier 3 is driven to move up and down by two lifting drive sources 7, so that its two carrier side plates 30 can be guided to move up and down on the connecting frame 22, ensuring that its lifting control position is accurate and its position is reliable and stable.

[0052] In one specific embodiment, such as Figure 3 and Figure 4 As shown, the lifting drive source 7 includes a drive rotation part 71 mounted on the mounting frame and a lifting drive screw 72 that is connected to the drive rotation part in a transmission manner, and a screw mating seat 73 mounted on the side plate of the carrier that passes through the mounting frame and is connected to the lifting drive screw in a transmission manner.

[0053] Specifically, the drive rotation unit 71 drives the lifting drive screw 72 to rotate, and its torque is transmitted to the screw mating seat 73, thereby driving the lifting displacement adjustment of the carrier side plate 30 relative to the mating frame 22.

[0054] This embodiment is only one implementation method of this case. Other lifting drive source mechanisms that can achieve lifting drive, such as cylinder lifting, servo gear drive, and cam arm drive, can also be used.

[0055] In one specific embodiment, such as Figure 5 and Figure 6 As shown, the milling spindle 4 includes a spindle body 41 and a spindle drive source 42 mounted on a spindle carrier 3. The spindle drive source is connected to the spindle body via a speed regulating mechanism 43.

[0056] This satisfies the speed control requirements of the milling spindle 4, making the milling control methods more diverse and the milling operation more reliable and stable.

[0057] In one specific embodiment, such as Figure 6 As shown, the speed regulating mechanism 43 includes a transmission bushing end 430 that is connected to the main spindle body and a main spindle transmission end that is connected to the main spindle drive source.

[0058] The transmission bushing end 430 can provide certain axial and radial follow-up deformation characteristics, and has anti-vibration and anti-fatigue features. It maintains stable and reliable transmission connection during machining and extends its effective service life.

[0059] As described above, this invention enables positional monitoring between the milling disc and the weld seam, meeting the requirements for correction and adjustment, and ensuring the high overlap between the milled weld seam and the longitudinal seam. The linear displacement drive, yaw adjustment drive, and lifting adjustment drive operate reliably and stably, resulting in reliable and stable machining operations and guaranteed milling quality. Automated operation is efficient and smooth, improving milling efficiency and extending the effective service life of the equipment.

[0061] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
