Description

Technical Field

[0002] In modern industrial manufacturing, the main structure of many equipment is mainly composed of a frame, and various instruments and components are installed on the frame. 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 clamp needs to be driven by a motor to rotate and drive the frame to flip so that the components on the frame can be welded; Since the clamping position of the frame is far from its center position, after the equipment is installed in the center of the frame, the center of the frame will bear a certain weight. During the flipping process, the clamping part of the frame is prone to deformation due to the offset of the center of gravity and the clamping force. This deformation will not only affect the accuracy and quality of welding, but may also cause the strength of the frame structure to decrease.

[0003] In order to solve the above problems, the present application proposes a welding equipment flipping device and method. Summary of the invention

[0014] A method for turning over equipment for welding, using the above-mentioned turning over device for welding, comprises the following steps: Step 1: Clamp the two ends of the frame to be welded by two rotating clamping assemblies respectively, so that the two square tube shells are placed in the middle of the frame; Step 2: The two multi-point clamping assemblies at both ends of the square tube shell are driven away from each other by a driver, and the multiple tubular elastic members on the two multi-point clamping assemblies respectively contact the edges of both sides of the frame, the contacting parts retract accordingly, and the non-contacting parts wrap around the edges of the frame to form a self-adaptive clamping, thereby realizing multi-point support for the frame; Step 3: When welding equipment at the clamping position of the tubular elastic part, the driving assembly can be used to drive the square tube shell to move along the frame and approach the support. At this time, the tubular elastic part moves on the frame to reserve a welding position. When the tubular elastic part moves on the frame, the air source is guided into the tubular elastic part through the air supply assembly, and the air can be blown to the clamping position of the frame through the air holes opened on the clamping tube, so as to achieve cleaning while moving and keep the welding position clean; Step 4: When the frame is flipped and 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 as to maintain the overall stress state of the frame within the elastic deformation threshold.

[0015] The above technical solution of the present invention has the following beneficial technical effects: 1. Clamp the two ends of the frame to be welded by two rotating clamping assemblies respectively, so that the two square tube shells are placed in the middle of the frame, and the two multi-point clamping assemblies at the two ends of the square tube shell are driven away from each other by the driver, and the multiple tubular elastic parts on the two multi-point clamping assemblies respectively contact the edges of the two sides of the frame, and the contacting parts shrink accordingly, and the non-contacting parts wrap the edges of the frame to form a self-adaptive clamping, so as to realize multi-point support for the frame, and convert the concentrated load of the traditional single-point clamping into multiple flexible support points distributed along the length of the frame, so as to reduce the local stress peak, effectively avoid the structural damage that may be caused by stress concentration, and provide a more stable foundation for the welding process; 2. Since the two multi-point clamping components at both ends of the square tube shell clamp the frame and form three points of support between the single rotating clamping component, a triangular support system is formed, which improves the support auxiliary strength and the support strength and stability of the entire clamping system. During the welding process, even in the face of complex force conditions, the triangular structure can effectively resist external interference and ensure that the frame always maintains an ideal position and posture, providing a strong guarantee for the welding operation; 3. When welding the clamping part, welding slag may exist in the clamping part. The present invention blows air to the clamping part to keep the clamping part clean. Specifically, the driving component can drive the square tube shell to move along the frame and approach the support. At this time, the tubular elastic part moves on the frame to reserve a welding position. When the tubular elastic part moves on the frame, the wind source is guided into the tubular elastic part through the air supply component, and the wind can be blown to the clamping part of the frame through the air holes opened on the clamping tube, so as to achieve cleaning while moving and keep the welding part clean. 4. When the frame is flipped and 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 tilting axis away from the tilted end, so that the overall stress state of the frame is maintained within the elastic deformation threshold. At this time, the tubular elastic parts of the multi-point clamping assembly and the distributed contact support formed by the frame work together to convert the concentrated load brought by the traditional single-point counterweight into a multi-point uniformly distributed load along the length of the frame, thereby achieving center of gravity balance while avoiding local stress over-limit.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0027] like Figure 1-9 As shown, the present invention provides a welding equipment flip device, comprising two supports 1; A rotating clamping assembly 2 for clamping a workpiece is installed on one adjacent side of the two supports 1, and a driving assembly 3 is installed on one adjacent side of the two rotating clamping assemblies 2. A transversely arranged square tube shell 4 is installed on the driving assembly 3, and the square tube shell 4 is driven by the driving assembly 3 to approach and move away from the support 1. Multi-point clamping assemblies 5 are arranged at both ends of the square tube shell 4. A driver 6 for driving the two multi-point clamping assemblies 5 to move away from and approach each other is installed on the square tube shell 4. The multi-point clamping assembly 5 includes a plurality of tubular elastic members 51 arranged in a rectangular array. 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.

[0028] First, the frame is clamped by rotating the clamping assembly 2. When welding the instrument on the frame, the driving assembly 3 works to drive the square tube shell 4 to move, reserving a position for the welding of the instrument. 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, and the tubular elastic parts 51 on the multi-point clamping assemblies 5 are in conflict with 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, and adjusts it to a position symmetrical to the tilt axis away from the inclined end, so as to maintain the overall stress state of the frame within the elastic deformation threshold.

[0029] 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, and the two loading boxes 52 are respectively arranged at the two ends of the square tube shell 4, and a plurality of tubular elastic members 51 are installed on the loading box 52 in an array rectangular shape. The two loading boxes 52 are driven away and closer by the driver 6.

[0030] The driver 6 is turned on, and 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 a plurality of tubular elastic members 51 are installed in a rectangular array on the loading boxes 52, the movement of the loading boxes 52 drives the tubular elastic members 51 to approach the workpiece together, thereby realizing self-adaptive clamping of the frame.

[0031] like Figure 3 and Figure 4 As shown, in this embodiment, the tubular elastic member 51 includes a fixed tube 511, and a plurality of fixed tubes 511 are installed in a rectangular array in a loading box 52. A spring 512 is installed in the fixed tube 511. A clamping tube 513 connected to the spring 512 is inserted at one end of the fixed tube 511. A ball 514 is installed at the end of the clamping tube 513 away from the fixed tube 511. A plurality of air holes 515 arranged at intervals are opened on the clamping tube 513, and a filter 516 is arranged in the air hole 515. A bellows 53 is installed at one end of the two loading boxes 52 that are close to each other. The fixed tube 511 is connected to the bellows 53, and an air supply component 8 for supplying air to the bellows 53 is installed in the square tube shell 4.

[0032] When the tubular elastic member 51 hits the edge of the frame, the edge of the frame generates pressure on the clamping tube 513, and the clamping tube 513 is forced to move toward the inside of the fixed tube 511, compressing the spring 512 in the fixed tube 511. At the same time, the air supply component 8 starts to work, and the generated wind is transported to the bellows 53. The wind enters the clamping tube 513 through the fixed tube 511 connected to the bellows 53, and is then blown out from the wind hole 515 on the clamping tube 513 to clean the dust on the frame to keep it clean. The filter 516 plays a role in blocking impurities, and the ball 514 makes the tubular elastic member 51 move more smoothly when in contact with the frame.

[0033] like Figure 2 and Figure 5 As shown, in this embodiment, the air supply assembly 8 includes a fan 81, and two partition blocks 41 are symmetrically installed in the square tube shell 4. The two partition blocks 41 are each provided with an installation groove, and the fans 81 are installed in the two installation grooves. The air outlet ends of the two fans 81 are each installed with a wind cover 82, and the wind cover 82 is connected to a spiral air duct 83, and the two spiral air ducts 83 are respectively connected to the two bellows 53.

[0034] After the fan 81 is powered on and started, it begins to operate and generate wind. The wind blown out by the fan 81 is gathered and guided by the wind cover 82 installed at its air outlet end. The wind flows along the wind cover 82 into the spiral air duct 83 connected to it. Since the two spiral air ducts 83 are respectively connected to the two bellows 53, the wind is transported to the corresponding bellows 53 through the spiral air duct 83, preparing for the subsequent air supply to the tubular elastic member 51.

[0035] like Figure 2 As shown, in this embodiment, the driver 6 includes a third motor 61, a gear 62 and two racks 63. The racks 63 are installed on the adjacent sides of the two bellows 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 is meshed 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 axis of the gear 62.

[0036] The third motor 61 is turned on, and its output end drives the gear 62 to rotate. Since the gear 62 is meshed with the two racks 63, and the two racks 63 are respectively installed on the adjacent sides 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 driving the bellows 53 installed with the racks 63 to move closer to or away from each other, and finally realize the opening and closing action of the multi-point clamping assembly 5.

[0037] like Figure 6 As shown, in this embodiment, the counterweight assembly 7 includes an electric slide rail 71 and a counterweight member 72. The electric slide rail 71 is installed at the bottom of the square tube shell 4, and the counterweight member 72 is installed at the driving end of the electric slide rail 71 and is driven by the electric slide rail 71 to move along the bottom of the square tube shell 4.

[0038] The electric slide rail 71 is powered on and started, and its driving end starts to move, driving the counterweight 72 installed on it to move along a 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.

[0039] like Figure 7As shown, in this embodiment, the counterweight member 72 includes a counterweight box 721, a counterweight ball 722 and a threaded sealing shaft 723. The counterweight box 721 is installed at the driving end of the electric slide rail 71. A plurality of counterweight balls 722 are arranged in 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 in the threaded hole.

[0040] According to actual needs, first unscrew the threaded sealing shaft 723 from the threaded hole at one end of the counterweight box 721, and 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 equipped with the counterweight balls 722 to move at the bottom of the square tube shell 4 to adjust the center of gravity of the device.

[0041] like Figure 1 and Figure 8 As shown, in this embodiment, the driving component 3 includes a guide rail seat 31, and the two guide rail seats 31 are respectively installed horizontally on the adjacent sides of the two rotating clamping components 2. A movable groove is opened in the guide rail seat 31, and a fixed block 32 is installed at one end of the movable groove. A second motor 33 is installed on one side of the fixed block 32, and a screw rod 34 is connected to the output end of the second motor 33. A movable seat 35 that slides with the movable groove is threadedly sleeved on the screw rod 34, and two support rods 36 are symmetrically installed on the movable seat 35. Two square tube shells 4 are respectively installed on the support rods 36 of the two movable seats 35, and a channel for the counterweight box 721 to pass through is formed between the two support rods 36.

[0042] The second motor 33 is started, and its output end drives the screw rod 34 to rotate. Since a moving seat 35 is threadedly sleeved on the screw rod 34, and the moving seat 35 slides in cooperation with the moving groove in the guide rail seat 31, the rotation of the screw rod 34 will cause the moving seat 35 to slide in the moving groove of the guide rail seat 31 along the guide rail direction. When the moving seat 35 slides, the square tube shell 4 installed on the support rod 36 is driven to move together through its symmetrically installed support rod 36. During the movement, the counterweight box 721 can pass smoothly through the channel between the two support rods 36.

[0043] like Figure 1 and Fig. 9As shown, in this embodiment, the rotating clamping assembly 2 includes a turntable 21, and the two adjacent sides of the turntables 21 are rotatably connected with the turntable 21, the middle part of the two turntables 21 is provided with an open groove 22, and the adjacent sides of the two turntables 21 are installed with a laterally arranged supporting block 23, a slider 241 is slidably arranged in the open groove 22, and the end of the slider 241 is installed with a clamping block 24 located on one side of the supporting block 23, a cylinder 25 is installed at one end in the open groove 22, the slider 241 is connected to the cylinder 25 and driven by the cylinder 25 to move along the open groove 22, and a first motor 101 is installed on the outer side of a support 1, and the output end of the first motor 101 is connected to the axis of a turntable 21.

[0044] The cylinder 25 is started, and the piston rod of the cylinder 25 is extended or retracted, driving the slider 241 connected thereto to slide in the open groove 22. When the slider 241 slides, the clamping block 24 installed at its end will approach or move away from the supporting block 23, thereby realizing the clamping or releasing operation of the frame. When the workpiece needs to be flipped, the first motor 101 is started, and the output end of the first motor 101 drives the turntable 21 connected thereto to rotate, thereby flipping the entire rotating clamping assembly 2 and the clamped workpiece together.

[0045] A method for turning over equipment for welding, using the above-mentioned turning over device for welding, comprises the following steps: Step 1: Clamp the two ends of the frame to be welded by two rotating clamping assemblies 2 respectively, so that the two square tube shells 4 are placed in the middle of the frame; Step 2: The two multi-point clamping assemblies 5 at both ends of the square tube shell 4 are driven away from each other by the driver 6, and the multiple tubular elastic members 51 on the two multi-point clamping assemblies 5 respectively contact the edges of both sides of the frame, and the contacting parts shrink accordingly, and the non-contacting parts wrap around the edges of the frame to form a self-adaptive clamping, thereby realizing multi-point support for the frame; Step 3: When welding equipment at the clamping position of the tubular elastic member 51, the driving assembly 3 can be used to drive the square tube shell 4 to move along the frame and approach the support 1. At this time, the tubular elastic member 51 moves on the frame to reserve a welding position. When the tubular elastic member 51 moves on the frame, the wind source is guided into the tubular elastic member 51 through the air supply assembly 8, and the wind can be blown to the clamping position of the frame through the air hole 515 opened on the clamping tube 513, so as to achieve cleaning while moving and keep the welding position clean; Step 4: When the frame is flipped and tilted by rotating the clamping assembly 2, the counterweight assembly 7 can be moved at the bottom of the square tube shell 4 and adjusted to a position symmetrical to the tilting axis away from the tilted end, so as to maintain the overall stress state of the frame within the elastic deformation threshold.

[0046] The specific working principle of the present invention is as follows: First, place the frame to be welded on the rotating clamping assembly 2, start the cylinder 25, and the cylinder 25 pushes the slider 241 to slide in the opening slot 22, driving 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; Next, the third motor 61 in the driver 6 is started, the third motor 61 drives the gear 62 to rotate, and the gear 62 drives the two racks 63 meshing therewith to slide, so that the two multi-point clamping assemblies 5 installed with the racks 63 are moved away from each other, and the tubular elastic member 51 on the multi-point clamping assembly 5 contacts the edges of both sides of the frame, the clamping tube 513 is squeezed and retracted, and the uncontacted part wraps the edge of the frame, thereby realizing multi-point support for the frame; When welding is required on a specific part of the frame, the second motor 33 in the driving assembly 3 is started, the second motor 33 drives the screw 34 to rotate, the screw 34 drives the moving seat 35 to slide in the moving groove of the guide rail seat 31, and the square tube shell 4 is driven by the support rod 36 to move along the frame and approach the support 1, and the tubular elastic member 51 moves on the frame accordingly, reserving a welding position, and at the same time, the fan 81 in the air supply assembly 8 is started, and the wind generated by the fan 81 enters the bellows 53 through the wind 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; If the frame is to be flipped and tilted, start the first motor 101, which drives the turntable 21 to rotate and flip the frame. During the flipping process, start the electric slide rail 71 in the counterweight assembly 7, which drives the counterweight 72 to move at the bottom of the square tube shell 4, and adjust the counterweight 72 to a position symmetrical to the tilting axis away from the tilting end, so as to maintain the overall stress state of the frame within the elastic deformation threshold and ensure the stability of the frame during the flipping process.

[0047] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention.
