Description

Technical Field

[0001] This invention relates to the field of welding auxiliary technology, and in particular to a flipping device and method for welding equipment. Background Technology

[0002] In modern industrial manufacturing, the main structure of many equipment consists of a frame, on which various instruments and components are installed. This frame structure design is widely used because it can provide good support and flexibility. However, in the actual welding process, two rotatable clamps are usually used to fix the two ends of the frame, and then various instruments are installed on the frame. In order to achieve all-round welding, the clamps need to be rotated by a motor to rotate the frame so that the components on the frame can be welded.

[0003] Because the clamping position of the frame is far from its center, after the instrument is installed in the center of the frame, the center of the frame will bear a certain weight. During the flipping process, due to the shift of the center of gravity and the effect of the clamping force, the clamping part of the frame is prone to deformation. This deformation will not only affect the accuracy and quality of welding, but may also lead to a decrease in the strength of the frame structure.

[0004] To address the aforementioned problems, this application proposes a flipping device and method for equipment welding. Summary of the Invention

[0005] This invention proposes a flipping device and method for welding equipment, which solves the problem in related technologies that after the equipment is installed in the center of the frame, the center of the frame will bear a certain weight, and during the flipping process, the clamping part of the frame is prone to deformation due to the shift of the center of gravity and the effect of clamping force.

[0006] The present invention proposes a turning device for welding equipment, comprising two supports;

[0007] Each of the two supports is equipped with a rotary clamping assembly for clamping the workpiece on an adjacent side. Each of the two rotary clamping assemblies is equipped with a drive assembly on an adjacent side. A transversely arranged square tube shell is mounted on the drive assembly, and the square tube shell is driven by the drive assembly to move closer to and away from the support. Multi-point clamping assemblies are provided at both ends of the square tube shell. A driver is mounted on the square tube shell to drive the two multi-point clamping assemblies to move away from and closer to each other. The multi-point clamping assembly includes multiple tubular elastic elements arranged in an array of rectangles.

[0008] A counterweight assembly is installed at the bottom of the square tube shell, and the position of the counterweight assembly at the bottom of the square tube shell is adjustable.

[0009] As a further optimization of the present invention, the multi-point clamping assembly also includes a loading box, with two loading boxes respectively disposed at both ends of a square tube shell, and a plurality of tubular elastic elements mounted on the loading box in an array of rectangles, and the two loading boxes being driven by a driver to move away from each other and closer together.

[0010] As a further optimization of the present invention, the tubular elastic element includes a fixed tube, and a plurality of the fixed tubes are installed in a rectangular array inside the loading box. A spring is installed inside the fixed tube, and a clamping tube connected to the spring is inserted into one end of the fixed tube. A ball bearing is installed at the end of the clamping tube away from the fixed tube. A plurality of spaced air holes are opened on the clamping tube, and a filter screen is installed in the air holes. Air boxes are installed at the adjacent ends of the two loading boxes. The fixed tube communicates with the air boxes. An air supply component for supplying air to the air boxes is installed inside the square tube shell.

[0011] As a further optimization of the present invention, the air supply assembly includes a fan, two partition blocks are symmetrically installed inside the square tube shell, each partition block has an installation groove, each installation groove has a fan installed inside, each fan has a hood installed at its outlet, the hood is connected to a spiral duct, and the two spiral ducts are respectively connected to two air boxes.

[0012] As a further optimization of the present invention, the driver includes a third motor, a gear and two racks. Racks are installed on adjacent sides of the two air boxes. The two racks slide through two partition blocks respectively. The gear is located in the middle of the square tube shell and is placed between the two racks. The gear meshes with the two racks. The third motor is installed in the square tube shell and is located above the gear. The output end of the third motor is connected to the shaft of the gear.

[0013] As a further optimization of the present invention, the counterweight assembly includes an electric slide rail and a counterweight. The electric slide rail is installed at the bottom of the square tube shell, and the counterweight is installed at the drive end of the electric slide rail and driven by it to move along the bottom of the square tube shell.

[0014] As a further optimization of the present invention, the counterweight includes a counterweight box, counterweight balls and a threaded sealing shaft. The counterweight box is installed on the drive end of the electric slide rail. Multiple counterweight balls are provided inside the counterweight box. A threaded hole is opened at one end of the counterweight box, and the threaded sealing shaft is threaded into the threaded hole.

[0015] As a further optimization of the present invention, the driving component includes a guide rail seat, two guide rail seats are respectively horizontally installed on adjacent sides of two rotating clamping components, a moving groove is formed in the guide rail seat, a fixed block is installed at one end of the moving groove, a second motor is installed on one side of the fixed block, the output end of the second motor is connected to a lead screw, a moving seat that slides with the moving groove is threaded on the lead screw, two support rods are symmetrically installed on the moving seat, two square tube shells are respectively installed on the support rods of the two moving seats, and a channel for the counterweight box to pass through is formed between the two support rods.

[0016] As a further optimization of the present invention, the rotary clamping assembly includes a turntable, with two turntables rotatably connected to each other on adjacent sides. Each of the two turntables has an opening slot in its center, and a laterally arranged support block is installed on each of the two turntables on adjacent sides. A slider is slidably disposed within the opening slot, and a clamping block located on one side of the support block is installed at the end of the slider. A cylinder is installed at one end of the opening slot, and the slider is connected to the cylinder and driven by the cylinder to move along the opening slot. A first motor is installed on the outer side of one of the supports, and the output end of the first motor is connected to the axis of one of the turntables.

[0017] A method for flipping equipment for welding, employing the aforementioned equipment welding flipping device, includes the following steps:

[0018] Step 1: Clamp both ends of the frame to be welded using two rotating clamping assemblies, so that the two square tube shells are placed in the middle of the frame;

[0019] Step 2: Drive the two multi-point clamping components at both ends of the square tube shell to move away from each other. Multiple tubular elastic elements on the two multi-point clamping components abut against the two side edges of the frame respectively. The abutting parts retract accordingly, and the non-abutting parts wrap around the edges of the frame to form a self-adaptive clamping, thereby achieving multi-point support for the frame.

[0020] Step 3: When welding instruments at the clamping part of the tubular elastic component, the square tube shell can be moved along the frame and closer to the support by the drive component. At this time, the tubular elastic component moves along the frame to reserve the welding position. When the tubular elastic component moves on the frame, the air supply component guides the air source into the tubular elastic component. The air can be blown to the clamping part of the frame through the air holes opened on the clamping tube, so as to clean while moving and keep the welding part clean.

[0021] Step 4: When the frame is tilted by rotating the clamping assembly, the counterweight assembly can be moved at the bottom of the square tube shell and adjusted to a position symmetrical to the tilt axis away from the tilted end, so that the overall stress state of the frame is maintained within the elastic deformation threshold.

[0022] The above-described technical solution of the present invention has the following beneficial technical effects:

[0023] 1. The two ends of the frame to be welded are clamped by two rotating clamping assemblies, so that the two square tube shells are placed in the middle of the frame. The driver drives the two multi-point clamping assemblies at both ends of the square tube shells to move away from each other. The multiple tubular elastic elements on the two multi-point clamping assemblies abut against the two side edges of the frame. The abutting parts retract accordingly, and the non-abutting parts wrap around the edges of the frame to form a self-adaptive clamping, realizing multi-point support for the frame. This transforms the concentrated load of traditional single-point clamping into multiple flexible support points distributed along the length of the frame, reducing local stress peaks and effectively avoiding structural damage that may be caused by stress concentration, providing a more stable foundation for the welding process.

[0024] 2. Because the two multi-point clamping components at both ends of the square tube shell form a three-point support between the clamping of the frame and the single rotating clamping component, it forms a triangular support system, which increases the support and assistance force and improves the support force and stability of the entire clamping system. During the welding process, even when facing complex stress conditions, this triangular structure can effectively resist external interference and ensure that the frame always maintains the ideal position and posture, providing a strong guarantee for the welding operation.

[0025] 3. When welding instruments at the clamping points, welding slag may be present. This invention addresses this by blowing air into the clamping points to keep them clean. Specifically, a drive assembly moves the square tubular shell along the frame and closer to the support. The tubular elastic element moves along the frame, creating space for welding. As the tubular elastic element moves, air is supplied to it via an air supply assembly. Air is blown onto the clamping points of the frame through air holes in the clamping tube, allowing for simultaneous movement and cleaning to maintain the cleanliness of the welding area.

[0026] 4. When the frame is tilted by rotating the clamping assembly, the counterweight assembly can be moved at the bottom of the square tube shell and adjusted to a position symmetrical to the tilt axis away from the tilted end. This keeps the overall stress state of the frame within the elastic deformation threshold. At this time, the tubular elastic element of the multi-point clamping assembly and the distributed contact support formed by the frame work together to transform the concentrated load brought by the traditional single-point counterweight into a multi-point uniformly distributed load along the length of the frame. This achieves balance of the center of gravity while avoiding local stress exceeding the limit. Attached Figure Description

[0037] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0038] like Figure 1-9 As shown, the present invention provides a turning device for welding equipment, comprising two supports 1;

[0039] Two supports 1 are each equipped with a rotating clamping assembly 2 for clamping the workpiece on one side of each adjacent support 1. Two rotating clamping assemblies 2 are each equipped with a driving assembly 3 on one side of each adjacent support 1. A square tube shell 4 is mounted on the driving assembly 3 and is driven by the driving assembly 3 to move closer to or away from the support 1. Multi-point clamping assemblies 5 are provided at both ends of the square tube shell 4. A driver 6 is mounted on the square tube shell 4 to drive the two multi-point clamping assemblies 5 to move away from or closer to each other. The multi-point clamping assembly 5 includes multiple tubular elastic elements 51 arranged in an array of rectangles.

[0040] A counterweight assembly 7 is installed at the bottom of the square tube shell 4, and the position of the counterweight assembly 7 at the bottom of the square tube shell 4 is adjustable.

[0041] First, the frame is clamped by the rotating clamping assembly 2. When welding instruments on the frame, the drive assembly 3 works to move the square tube shell 4, reserving a position for welding the instruments. At the same time, the driver 6 drives the multi-point clamping assemblies 5 at both ends of the square tube shell 4 to move away from each other. The tubular elastic element 51 on the multi-point clamping assembly 5 abuts against the frame to achieve self-adaptive clamping. When the frame is flipped, the counterweight assembly 7 adjusts its position at the bottom of the square tube shell 4, adjusting it to a position symmetrical to the tilt axis away from the tilted end, maintaining the overall stress state of the frame within the elastic deformation threshold.

[0042] like Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, the multi-point clamping assembly 5 also includes a loading box 52. The two loading boxes 52 are respectively disposed at both ends inside the square tube shell 4. Multiple tubular elastic elements 51 are mounted on the loading box 52 in an array rectangle. The two loading boxes 52 are driven away from and close to each other by the driver 6.

[0043] When the driver 6 is turned on, the power of the driver 6 is transmitted to the two loading boxes 52, causing them to move in opposite directions inside the square tube shell 4. Since multiple tubular elastic elements 51 are mounted in an array rectangle on the loading box 52, the movement of the loading box 52 drives the tubular elastic elements 51 to move closer to the workpiece, thereby achieving self-adaptive clamping of the frame.

[0044] like Figure 3 and Figure 4As shown, in this embodiment, the tubular elastic element 51 includes a fixed tube 511. Multiple fixed tubes 511 are installed in a rectangular array inside the loading box 52. A spring 512 is installed inside the fixed tube 511. One end of the fixed tube 511 is inserted into a clamping tube 513 connected to the spring 512. A ball bearing 514 is installed at the end of the clamping tube 513 away from the fixed tube 511. Multiple spaced air holes 515 are opened on the clamping tube 513. A filter screen 516 is installed inside the air hole 515. Air boxes 53 are installed at the ends of the two loading boxes 52 that are close to each other. The fixed tube 511 is connected to the air box 53. An air supply component 8 for supplying air to the air box 53 is installed inside the square tube shell 4.

[0045] When the tubular elastic element 51 comes into contact with the edge of the frame, the edge of the frame exerts pressure on the clamping tube 513. The clamping tube 513 moves into the fixed tube 511 under force, compressing the spring 512 inside the fixed tube 511. At the same time, the air supply assembly 8 starts to work, and the generated air is delivered to the air box 53. The air enters the clamping tube 513 through the fixed tube 511 connected to the air box 53, and is then blown out from the air hole 515 on the clamping tube 513 to clean the dust on the frame and keep it clean. The filter screen 516 plays the role of blocking impurities, and the ball bearing 514 makes the tubular elastic element 51 move more smoothly when it comes into contact with the frame.

[0046] like Figure 2 and Figure 5 As shown, in this embodiment, the air supply component 8 includes a fan 81. Two partition blocks 41 are symmetrically installed inside the square tube shell 4. Each partition block 41 has an installation groove, and each installation groove has a fan 81 installed inside. Each fan 81 has a hood 82 installed at its air outlet. A spiral air duct 83 is connected to the hood 82, and the two spiral air ducts 83 are respectively connected to two air boxes 53.

[0047] After the fan 81 is powered on and started, it begins to operate and generate wind. The air blown out by the fan 81 is gathered and guided by the hood 82 installed at its air outlet. The air enters the spiral duct 83 connected to the hood 82. Since the two spiral ducts 83 are connected to the two air boxes 53 respectively, the air is transported to the corresponding air box 53 through the spiral ducts 83, preparing for the subsequent supply of air to the tubular elastic element 51.

[0048] like Figure 2 As shown, in this embodiment, the driver 6 includes a third motor 61, a gear 62, and two racks 63. Racks 63 are installed on adjacent sides of the two air boxes 53. The two racks 63 slide through the two partition blocks 41 respectively. The gear 62 is located in the middle of the square tube shell 4 and is placed between the two racks 63. The gear 62 meshes with the two racks 63. The third motor 61 is installed in the square tube shell 4 and is located above the gear 62. The output end of the third motor 61 is connected to the shaft of the gear 62.

[0049] When the third motor 61 is turned on, its output end drives the gear 62 to rotate. Since the gear 62 meshes with the two racks 63, and the two racks 63 are respectively installed on the adjacent side of the two bellows 53 and slide through the partition block 41, the rotation of the gear 62 will drive the two racks 63 to slide along the partition block 41, thereby causing the bellows 53 with racks 63 to move closer and further away from each other, and finally realize the opening and closing action of the multi-point clamping component 5.

[0050] like Figure 6 As shown, in this embodiment, the counterweight assembly 7 includes an electric slide rail 71 and a counterweight 72. The electric slide rail 71 is installed at the bottom of the square tube shell 4, and the counterweight 72 is installed at the drive end of the electric slide rail 71 and is driven by it to move along the bottom of the square tube shell 4.

[0051] When the electric slide rail 71 is powered on, its drive end starts to move, driving the counterweight 72 installed on it to move along the predetermined track at the bottom of the square tube shell 4. By adjusting the position of the counterweight 72 at the bottom of the square tube shell 4, the center of gravity distribution of the entire device is changed.

[0052] like Figure 7 As shown, in this embodiment, the counterweight 72 includes a counterweight box 721, counterweight balls 722 and a threaded sealing shaft 723. The counterweight box 721 is installed on the drive end of the electric slide rail 71. Multiple counterweight balls 722 are provided inside the counterweight box 721. A threaded hole is opened at one end of the counterweight box 721, and the threaded sealing shaft 723 is threadedly connected to the threaded hole.

[0053] According to actual needs, first unscrew the threaded sealing shaft 723 from the threaded hole at one end of the counterweight box 721. Then, the number of counterweight balls 722 in the counterweight box 721 can be added or reduced. After adjusting the counterweight, screw the threaded sealing shaft 723 back into the threaded hole for sealing. After that, the electric slide rail 71 drives the counterweight box 721 with the counterweight balls 722 installed to move at the bottom of the square tube shell 4 to adjust the center of gravity of the device.

[0054] like Figure 1 and Figure 8 As shown, in this embodiment, the drive assembly 3 includes a guide rail seat 31. Two guide rail seats 31 are respectively horizontally installed on adjacent sides of two rotating clamping assemblies 2. A moving groove is provided in the guide rail seat 31. A fixing block 32 is installed at one end of the moving groove. A second motor 33 is installed on one side of the fixing block 32. The output end of the second motor 33 is connected to a lead screw 34. A moving seat 35 that slides with the moving groove is threaded on the lead screw 34. Two support rods 36 are symmetrically installed on the moving seat 35. Two square tube shells 4 are respectively installed on the support rods 36 of the two moving seats 35. A channel for the counterweight box 721 to pass through is formed between the two support rods 36.

[0055] The second motor 33 starts, and its output end drives the lead screw 34 to rotate. Since the lead screw 34 is threaded with a movable seat 35, and the movable seat 35 is slidably engaged with the movable groove in the guide rail seat 31, the rotation of the lead screw 34 will cause the movable seat 35 to slide along the guide rail direction in the movable groove of the guide rail seat 31. When the movable seat 35 slides, it drives the square tube shell 4 installed on the support rod 36 to move together through the support rod 36 symmetrically installed. During the movement, the counterweight box 721 can pass smoothly in the channel between the two support rods 36.

[0056] like Figure 1 and Figure 9 As shown, in this embodiment, the rotating clamping assembly 2 includes a turntable 21. Two turntables 21 are rotatably connected to each other on adjacent sides. An opening slot 22 is provided in the middle of each of the two turntables 21. A horizontally arranged bearing block 23 is installed on each of the two turntables 21 on adjacent sides. A slider 241 is slidably arranged in the opening slot 22. A clamping block 24 located on one side of the bearing block 23 is installed at the end of the slider 241. A cylinder 25 is installed at one end of the opening slot 22. The slider 241 is connected to the cylinder 25 and driven by the cylinder 25 to move along the opening slot 22. A first motor 101 is installed on the outside of a support 1. The output end of the first motor 101 is connected to the axis of a turntable 21.

[0057] When cylinder 25 is activated, the piston rod of cylinder 25 extends or retracts, causing the slider 241 connected to it to slide within the opening slot 22. When the slider 241 slides, the clamping block 24 installed at its end will move closer to or further away from the bearing block 23, thereby achieving the clamping or releasing operation of the frame. When it is necessary to flip the workpiece, the first motor 101 is activated, and the output end of the first motor 101 drives the turntable 21 connected to it to rotate, thereby causing the entire rotating clamping assembly 2 and the clamped workpiece to flip together.

[0058] A method for flipping equipment for welding, employing the aforementioned equipment welding flipping device, includes the following steps:

[0059] Step 1: Clamp both ends of the frame to be welded using two rotating clamping components 2, so that the two square tube shells 4 are placed in the middle of the frame;

[0060] Step 2: Drive the driver 6 to move the two multi-point clamping components 5 at both ends of the square tube shell 4 away from each other. The multiple tubular elastic elements 51 on the two multi-point clamping components 5 respectively abut against the two side edges of the frame. The abutting parts retract accordingly, and the non-abutting parts wrap around the edges of the frame to form a self-adaptive clamping, thereby achieving multi-point support for the frame.

[0061] Step 3: When welding instruments at the clamping part of the tubular elastic element 51, the square tube shell 4 can be driven to move along the frame and approach the support 1 by the drive component 3. At this time, the tubular elastic element 51 moves along the frame to reserve the welding position. When the tubular elastic element 51 moves on the frame, the air supply component 8 guides the air source into the tubular elastic element 51. The air can be blown to the clamping part of the frame through the air hole 515 opened on the clamping tube 513, so as to clean while moving and keep the welding part clean.

[0062] Step 4: When the frame is flipped and tilted by rotating the clamping component 2, the counterweight component 7 can be moved at the bottom of the square tube shell 4 and adjusted to a position symmetrical to the tilt axis away from the tilted end, so as to maintain the overall stress state of the frame within the elastic deformation threshold.

[0063] The specific working principle of this invention is as follows:

[0064] First, place the frame to be welded at the rotating clamping assembly 2, start the cylinder 25, the cylinder 25 pushes the slider 241 to slide in the opening slot 22, and drives the clamping block 24 to clamp the two ends of the frame. At this time, the two square tube shells 4 are located in the middle of the frame.

[0065] Next, the third motor 61 in the driver 6 is started. The third motor 61 drives the gear 62 to rotate. The gear 62 drives the two racks 63 that mesh with it to slide, so that the two multi-point clamping components 5 with racks 63 are moved away from each other. The tubular elastic element 51 on the multi-point clamping component 5 abuts against the two sides of the frame. The clamping tube 513 is squeezed and retracted. The part that does not abuts wraps around the edge of the frame, thus achieving multi-point support for the frame.

[0066] When welding is required on a specific part of the frame, the second motor 33 in the drive assembly 3 is started. The second motor 33 drives the lead screw 34 to rotate. The lead screw 34 drives the moving seat 35 to slide in the moving groove of the guide rail seat 31. The square tube shell 4 is moved along the frame and close to the support 1 through the support rod 36. The tubular elastic element 51 moves on the frame accordingly to reserve the welding position. At the same time, the fan 81 in the air supply assembly 8 is started. The air generated by the fan 81 enters the air box 53 through the air cover 82 and the spiral air duct 83, and then enters the clamping tube 513 through the fixed tube 511 and is blown out from the air hole 515 to clean the clamping part of the frame.

[0067] To tilt the frame, the first motor 101 is started, which drives the turntable 21 to rotate, causing the frame to tilt. During the tilting process, the electric slide rail 71 in the counterweight assembly 7 is started, which drives the counterweight 72 to move at the bottom of the square tube shell 4, adjusting the counterweight 72 to a position symmetrical to the tilt axis away from the tilted end, maintaining the overall stress state of the frame within the elastic deformation threshold, and ensuring the stability of the frame during the tilting process.

[0068] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of the invention and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of the invention should be included within the protection scope of the invention.
