Description

Technical Field

[0001] This invention relates to the field of machining technology, specifically to a rotating worktable for equipment and a welding method for the equipment. Background Technology

[0002] In the process of industrialized machining, heavy equipment often needs to be processed and manufactured. Welding is a common machining method. When welding equipment, pre-forming is usually used first, and then further welding and forming are carried out.

[0003] During the welding process, both sides of the equipment need to be welded, requiring the equipment to be flipped. Due to the large weight of the equipment, a flipping machine is often used for flipping. At the beginning and end of the flipping process, the drive equipment is subjected to a large load due to the angle, which can easily lead to damage and wear, and also cause inconvenience in use. At the same time, since the equipment is pre-welded, it will be subjected to a large impact force during the flipping process, which will affect the welding quality of the equipment and cause inconvenience in practical application.

[0004] Therefore, this invention proposes a machine flipping workbench and a machine welding method. The welding of the machine is achieved through the cooperation of the first flipping frame and the second flipping frame. The buffer mechanism effectively reduces the load on the driving equipment and the impact force during flipping, ensuring the stable use of the equipment and the quality of the welding. Summary of the Invention

[0005] The purpose of this invention is to provide a rotating worktable and a welding method for equipment, so as to solve the problems of existing rotating equipment having a large working load on the driving equipment during rotation, a large impact force during the rotation process, which affects the stable use of the equipment and the welding quality.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a machine tilting worktable, comprising a first tilting mechanism and a second tilting mechanism;

[0007] The first and second flipping mechanisms work together to flip the equipment to be welded by 180°; the second flipping mechanism is movable to transfer the flipped equipment to be welded from the first welding station to the second welding station.

[0008] Both the first and second flipping mechanisms are equipped with a flipping frame, which includes two vertical flipping arms. The flipping frame rotates around the junction of the two flipping arms and is provided with a drive connection part in the direction away from the junction. The drive power unit drives the drive connection part and drives the flipping frame to rotate.

[0009] The first and second flipping mechanisms each include a toothed flipping arm that meshes with each other. When the first and second flipping mechanisms are engaged, the two toothed flipping arms mesh with each other.

[0010] Both the first and second flipping mechanisms are equipped with a buffer mechanism, which is located between the back sides of the two flipping arms. The buffer mechanism includes a spring. During each flipping process, the spring goes through three states: compression, restoration, and tension. At the beginning of the flipping, it provides a positive thrust that helps the flipping frame rotate and reduces the workload of the drive power unit. At the end of the flipping, it provides a reverse thrust that inhibits the rotation of the flipping frame, thus buffering the flipping frame and reducing the impact force during the flipping.

[0011] Furthermore, the second flipping mechanism includes a mounting plate. The flipping frame, buffer mechanism, and drive power unit in the second flipping mechanism are all located above the mounting plate. The mounting plate is slidably mounted on the slide rail. The drive unit drives the mounting plate to slide. When the mounting plate moves to the first limit position, the toothed flipping arm of the flipping frame in the second flipping mechanism cooperates with the toothed flipping arm of the flipping frame in the first flipping mechanism. When the mounting plate moves to the second limit position, the flipping frame in the second flipping mechanism cooperates with the welding robot at the second welding station.

[0012] Furthermore, the buffer mechanism includes a first buffer mechanism, in which a fixed arc-shaped channel is provided, and a first arc-shaped connecting rod is inserted into the arc-shaped channel. The two ends of the first arc-shaped connecting rod are respectively hinged to the two flipping arms of the flipping frame. The first arc-shaped connecting rod is concentrically arranged with the arc-shaped channel and with the rotation center of the flipping frame. A first connecting part is fixedly provided in the arc-shaped channel. A second connecting part and a third connecting part are respectively provided on the first arc-shaped connecting rod on both sides of the first connecting part. A first spring is provided between the first connecting part and the second connecting part, and the two ends of the first spring are respectively fixedly connected to the first connecting part and the second connecting part. A second spring is provided between the first connecting part and the third connecting part, and the two ends of the second spring are respectively fixedly connected to the first connecting part and the third connecting part.

[0013] Furthermore, when one of the first springs and the second spring is in a compressed state, the other is in a stretched state; when one of them is in a free state, the other is also in a free state.

[0014] Furthermore, the buffer mechanism includes a second buffer mechanism, in which a movable arc-shaped channel is provided. A second arc-shaped connecting rod and a third arc-shaped connecting rod are inserted into the arc-shaped channel. A third spring is fixedly connected between the second arc-shaped connecting rod and the third arc-shaped connecting rod. The third spring is located in the arc-shaped channel throughout the flipping process of the flipping frame. The other ends of the second arc-shaped connecting rod and the third arc-shaped connecting rod are respectively hinged to the two flipping arms of the flipping frame. The second arc-shaped connecting rod, the third arc-shaped connecting rod, and the arc-shaped channel are concentrically arranged and eccentrically arranged with respect to the rotation center of the flipping frame. One of the second arc-shaped connecting rod and the third arc-shaped connecting rod is fixedly arranged with the hinge part of the flipping arm, and the other is slidably arranged with the hinge part of the flipping arm.

[0015] Furthermore, when the hinge portion of the second or third arc-shaped connecting rod is slidably connected to the flip arm, a slide rail is provided on the corresponding flip arm, and a slider is provided on the slide rail, with the slider fixedly connected to the hinge portion.

[0016] Furthermore, at the initial stage of the flipping frame, the torque applied by the third spring to the flipping frame in the rotation direction is greater than the torque in the opposite rotation direction; as the flipping is about to end, the torque applied by the third spring to the flipping frame in the rotation direction is less than the torque in the opposite rotation direction.

[0017] The welding method for the equipment's tilting worktable includes the following steps:

[0018] The position where the first tilting frame begins to rotate clockwise is recorded as the first position. The position where it begins to rotate counterclockwise after rotating 90° from the first position is recorded as the second position. The position where the second tilting frame begins to rotate counterclockwise is recorded as the first position. The position where it begins to rotate clockwise after rotating 90° from the first position is recorded as the second position.

[0019] S1. The welding robot at the first station welds one side of the equipment to be welded on the first flipping frame in the first position.

[0020] S2. After welding is completed on one side of the equipment, the first flipping frame flips over, and the second flipping frame flips from the first position to the second position at the welding station on the other side of the equipment and moves to the first flipping frame to cooperate with the first flipping frame.

[0021] S3. The second tilting frame rotates clockwise and, after rotating to the first position, drives the equipment back to the welding station on the other side of the equipment, where the welding robot performs welding on the other side of the equipment; the first tilting frame rotates and, after rotating to the first position, completes the tilting process.

[0022] S4. Place the equipment that needs to be welded again on the first flipping frame, and transfer the welded equipment to the second flipping frame;

[0023] S5. Repeat S1-S4 to complete the cyclic welding of the equipment.

[0024] Furthermore, in S2-S3, during the cooperation between the first flipping frame and the second flipping frame, the first flipping frame first flips from the first position by an angle greater than or equal to 80° and less than 90°; the second flipping frame first flips from the first position by 90° to the second position, and after cooperating with the first flipping frame, the first flipping frame continues to flip until the second position; then, the second flipping frame flips by 90° to the first position.

[0025] The beneficial effects of this invention are:

[0026] 1. The present invention employs a first flipping frame and a second flipping frame, which can flip the equipment to be welded by 180°, thereby enabling welding on both sides of the equipment and completing the entire welding process;

[0027] 2. This invention can provide assistance and buffering to the tilting frame during the tilting process, effectively drive the working load of the equipment, reduce energy consumption, and effectively avoid the impact force during tilting, which has a positive effect on ensuring the service life of the equipment and the welding quality.

Detailed Implementation

[0039] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention.

[0040] Example 1

[0041] like Figure 1-6 As shown, in this embodiment, the flipping workbench is installed in the pit 1, and a first flipping mechanism 2 and a second flipping mechanism 3 are installed in the pit 1. The first flipping mechanism 2 and the second flipping mechanism 3 cooperate to flip the equipment for welding.

[0042] The first flipping mechanism 2 includes a first support base 23 and a first flipping frame 24. The first flipping frame 24 includes a first flipping frame body 241, a first hinge support part 242 and a first drive connection part 243. The first hinge support part 242 cooperates with the first support base 23 so that the first flipping frame body 241 is supported on the first support base 23. A wear-resistant block is provided between the first flipping frame 24 and the first support base 23. The first drive connection part 243 is hinged to the telescopic rod of the first hydraulic cylinder 21 for driving the first flipping frame 24 to rotate. The cylinder end of the first hydraulic cylinder 21 is hinged to the first mounting base 22. A first buffer mechanism 4 is provided below the first flipping frame 24.

[0043] The second tilting mechanism 3 includes a second support base 33 and a second tilting frame 34. The second tilting frame 34 includes a second tilting frame body 341, a second hinge support part 342 and a second drive connection part 343. The second hinge support part 342 cooperates with the second support base 33, so that the second tilting frame body 341 is supported on the second support base 33. A second wear-resistant block is provided between the second tilting frame 34 and the second support base 33. The second drive connection part 343 is hinged to the telescopic rod of the second hydraulic cylinder 31 for driving the second tilting frame 34 to rotate. The cylinder end of the second hydraulic cylinder 31 is hinged to the second mounting base 32. A first buffer mechanism 4 is provided below the second tilting frame 34.

[0044] The second support base 33 and the second hydraulic cylinder 31 are mounted on the mounting plate 35. The first slider 351 and the first slide rail 36 are provided below the mounting plate 35. The first slide rail 36 cooperates with the first slider 351. The threaded connection part 352 is also provided below the mounting plate 35. The drive motor 37 is connected to the lead screw 371. The lead screw 371 is threadedly connected to the threaded connection part 352.

[0045] Both the first tilting frame body 241 and the second tilting frame body 341 are L-shaped and include two tilting arms. The tilting arms on one side that cooperate with each other are interlocking strip teeth. The mounting plate 35 and the first hydraulic cylinder 21 do not interfere with each other in space, and the first buffer mechanism 4 in the first tilting frame 24 and the second tilting frame 34 do not interfere with each other in space.

[0046] Both the first buffer mechanism 4 in the first flipping frame 24 and the second flipping frame 34 include a fixed base 41. The width of the fixed base 41 is less than or equal to the width of the aforementioned strip tooth, so that the first buffer mechanism 4 in the first flipping frame 24 and the second flipping frame 34 do not interfere with each other in space. An arc-shaped channel 411 is provided in the fixed base 41, and a first connecting part 412 is fixedly provided in the arc-shaped channel 411. A first arc-shaped connecting rod 42 is provided through the first connecting part 412. A first hinge part 425 and a second hinge part 426 are respectively provided at both ends of the first arc-shaped connecting rod 42. The first hinge part 425 and the second hinge part 426 are respectively connected to the main body of the first flipping frame. The two flipping arms of 241 are connected on their back sides. A second connecting part 421 is provided on the first arc-shaped connecting rod 42 on one side of the first connecting part 412, and a third connecting part 422 is provided on the first arc-shaped connecting rod 42 on the other side of the first connecting part 412. A first spring 423 is provided between the first connecting part 412 and the second connecting part 421, and the two ends of the first spring 423 are fixedly connected to the first connecting part 412 and the second connecting part 421 respectively. A second spring 424 is provided between the first connecting part 412 and the third connecting part 422, and the two ends of the second spring 424 are fixedly connected to the first connecting part 412 and the third connecting part 422 respectively.

[0047] In this embodiment, when the first tilting frame 24 rotates from the first state through an intermediate state to the second state, in the first state, the right-side second spring 424 is compressed, and the compressed second spring 424 exerts an upward force on the third connecting part 422, while the left-side first spring 423 is stretched, and the stretched first spring 423 exerts a downward force on the second connecting part 421. Under the drive of the first hydraulic cylinder 21, the thrust of the second spring 424 and the tension of the first spring 423 both contribute to the rotation of the first tilting frame 24, thereby helping to reduce the load on the first hydraulic cylinder 21. When rotating to the intermediate state, such as 45°C, the first... Both spring 423 and the second spring 424 are in a freely extended state, meaning they do not generate additional thrust or tension. When rotation continues, the first spring 423 is in a compressed state, while the second spring 424 is in a stretched state. At this time, the thrust of the first spring 423 will slow down the rotation of the first tilting frame 24, while the tension of the second spring 424 will also hinder the rotation of the tilting frame. This buffers the rotation of the first tilting frame 24, making the rotation more stable and safe. On the other hand, it also helps to reduce the impact force between the first tilting frame 24 and the first support base 23, which can slow down the wear of the wear-resistant blocks, help extend the service life of the equipment, and reduce maintenance and replacement costs.

[0048] When the first tilting frame 24 rotates from the second state to the first state, the process is the reverse of the above, and will not be described again.

[0049] Example 2

[0050] like Figure 1 As shown in Figures 7-9, in this embodiment, only the first buffer mechanism 4 is replaced with the second buffer mechanism 5. The rest is the same as in Embodiment 1, so it will not be described again. The second buffer mechanism 5 is located in the pit 1 and does not interfere with the pit 1 and / or the mounting plate 35 in space. The first flipping frame 24 and the second flipping frame 34 do not interfere with the second buffer mechanism 5 in space.

[0051] In this embodiment, the second buffer mechanism 5 includes an arc-shaped sleeve 51, within which a second arc-shaped connecting rod 52 and a third arc-shaped connecting rod 53 are disposed. One end of the second arc-shaped connecting rod 52 is connected to a third hinge portion 521, which is connected to the back side of one flipping arm of the first flipping frame 24. One end of the third arc-shaped connecting rod 53 is connected to a fourth hinge portion 531, which is connected to the back side of the other flipping arm of the first flipping frame 24. The second arc-shaped connecting rod 52... A first limiting ring is provided at the end of the third arc-shaped connecting rod 53 that mates with the arc-shaped sleeve 51, and a second limiting ring is provided at both ends of the arc-shaped sleeve 51. The first limiting ring and the second limiting ring cooperate to prevent the second arc-shaped connecting rod 52 and the third arc-shaped connecting rod 53 from separating from the arc-shaped sleeve 51. A third spring 54 is provided between the two ends of the second arc-shaped connecting rod 52 and the third arc-shaped connecting rod 53 that are close to each other. The two ends of the third spring 54 are fixedly connected to the second arc-shaped connecting rod 52 and the third arc-shaped connecting rod 53, respectively.

[0052] The difference between this embodiment and embodiment 1 is that in embodiment 1, the rotation centers of the first arc-shaped connecting rod 42 and the first flipping frame 24 are concentric, while in this embodiment, the rotation centers of the second arc-shaped connecting rod 52 and the third arc-shaped connecting rod 53 are not concentric with the rotation centers of the first flipping frame 24.

[0053] In this embodiment, the third hinge 521 and the fourth hinge 531 connected to the first flipping frame 24 are respectively fixedly connected to the flipping arm of the first flipping frame 24 and movably connected to the flipping arm of the first flipping frame 24. For example, a second slide rail 55 is provided on the longer flipping arm of the first flipping frame 24, and a second slider 56 is provided on the second slide rail 55. The second slider 56 is connected to the third hinge 521. In this embodiment, during the entire flipping process of the first flipping frame 24, the second slider 56 does not separate from each other.

[0054] In this embodiment, when the first tilting frame 24 rotates from the first state to the second state, the third spring 54 is in a stretched state. At this time, the third spring 54 simultaneously provides tension to both tilting arms. As shown in the figure, when the centers of the second arc-shaped connecting rod 52 and the third arc-shaped connecting rod 53 are located to the left of the tilting center horizontally, the torque connected to the second arc-shaped connecting rod 52 is greater than the torque connected to the third arc-shaped connecting rod 53, thereby helping to reduce the load on the first hydraulic cylinder 21. During the rotation, as the second slider 56 moves, the lever arm gradually increases while the third spring 54 gradually changes to a compressed state, thereby providing a greater torque and thus playing a buffering role. The process from the second state to the first state is the opposite of the above process, which will not be described in detail here.

[0055] The principle of this invention is as follows:

[0056] In the process of using this invention, the equipment to be welded is transferred to the first flipping frame 24. After the welding robot at the welding station completes welding on one side on the first flipping frame 24, it is flipped. During the flipping process, it is first flipped to approximately 90°. Figure 1 The diagram shows the state after the flip. Before the flip, the longer flip arm is horizontal, while the toothed flip arm is vertical. At this time, the drive motor 37 moves and drives the mounting plate 35 to move on the first slide rail 36 via the lead screw 371. During the movement, the toothed flip arm under the second flip frame 34 cooperates with the toothed flip arm under the first flip frame 24. At this time, the first flip frame 24 can be flipped to 90°, and then the second flip frame 34 flips. The toothed flip arm under the second flip frame 34 cooperates with the equipment. After the flip is completed, the drive motor 37 moves to pull the mounting plate 35 back to the position where the action started. The welding robot at this position completes the welding work on the other side.

[0057] During use, the invention can provide assistance or buffering during the tilting process through the first buffer mechanism 4 or the second buffer mechanism 5. This helps to reduce the load on the hydraulic system, reduce energy consumption, and ensure the service life of the hydraulic system. On the other hand, it can avoid the impact of large forces during rotation, reduce wear and deformation during equipment operation, and play a positive role in reducing maintenance and repair costs.

[0058] This invention is not limited to the preferred embodiments described above. Anyone can derive other forms of products under the guidance of this invention. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this invention.
