Description

Technical Field

[0001] The invention relates to the technical field of lifting and positioner, in particular to a lifting and positioner used for deep penetration welding. Background Art

[0002] The positioner is a special welding auxiliary equipment, which is suitable for welding position shifting of rotary work to obtain the ideal processing position and welding speed. It can be used with the manipulator and welding machine to form an automatic welding center, and can also be used for workpiece position shifting during manual operation.

[0003] At present, when the positioner cooperates with the deep welding robot to weld the workpiece, the workpiece needs to be pre-fixed on the rotating mechanism of the positioner. However, this processing method has limitations for the workpiece. Since the workpiece needs to be fixed on the positioner with a clamp, the clamp independently fixed on the rotating mechanism cannot meet the requirements of the coordinated welding of multiple workpieces. At the same time, specific clamps will also hinder the welding operation.

[0004] In view of the above, the present invention designs a lifting and positioner for deep penetration welding to solve the above problems. Summary of the invention

[0009] The rotation-assisting assembly comprises a rocker arm, a chassis movably mounted on the rocker arm, and a motor mounted in the chassis;

[0010] The calibration assembly comprises two vertical rods fixedly mounted on the top of the rocker arm, a reinforcement ring fixedly mounted on the top of the two vertical rods, and a pad installed in the middle of the reinforcement ring;

[0016] A clamp is fixedly mounted on the outer end of the hydraulic sub-rod in the hydraulic component.

[0017] In a preferred example, the present invention can be further configured as follows: the rocker arm is an L-shaped structure as a whole, and two symmetrically distributed slideways are opened on the outside of the rocker arm, and the two slide plates on the top of the chassis are adapted to penetrate into the two slideways.

[0018] In a preferred example, the present invention can be further configured as follows: the vertical rods and the reinforcement rings are both made of stainless steel, and symmetrically distributed sleeves are installed at both ends of the reinforcement ring away from the two vertical rods.

When the ports of two adjacent workpieces are fitted and pressed by the calibration component, the multiple workpieces that are tightly pressed and fixed can obtain a sufficiently stable bearing force. As the welding robot approaches the workpieces, the calibration component can prevent the multiple workpieces from being pressed and falling off. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] To make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in combination with specific implementations and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0042] It is to be understood that these descriptions are exemplary only and are not intended to limit the scope of the invention.

[0043] A lifting and positioner for deep penetration welding provided by some embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0044] Embodiment 1:

[0045] Combination Figure 1-Figure 9 As shown, the present invention provides a lifting and positioner for deep penetration welding, comprising a component to be welded 400, a weldment clamping mechanism 500 arranged outside the component to be welded 400, a rotating component 300 installed on the weldment clamping mechanism 500, a turning mechanism 100 movably installed on the rotating component 300, and a calibration component 200 installed on the turning mechanism 100 and the weldment clamping mechanism 500;

[0046] The flipping mechanism 100 includes a rotation-assisting assembly 120;

[0047] The rotation-assisting assembly 120 includes a rocker arm 121, a chassis 180 movably mounted on the rocker arm 121, and a motor 190 mounted in the chassis 180;

[0048] The calibration assembly 200 includes two vertical rods 210 fixedly mounted on the top of the rocker arm 121, a reinforcement ring 220 fixedly mounted on the top of the two vertical rods 210, and a foot 230 mounted in the middle of the reinforcement ring 220;

[0049] The rotating assembly 300 includes a gear plate 320 driven by the motor 190, a base 310 installed in the gear plate 320, and a base 340 disposed on the top of the base 310. A ring groove is provided in the rotating plate on the top of the base 340.

[0050] The weldment clamping mechanism 500 includes a main sealing ring 510 installed on the top of the base 340, a first rotating ring 520 movably installed on the outside of the base 340, two tightening rods 530 installed in the first rotating ring 520, a second rotating ring 540 fixedly installed on the top of the two tightening rods 530, a booster gasket 550 arranged on the top of the second rotating ring 540, and a secondary sealing ring 560 installed at the bottom of the booster gasket 550.

[0051] When the current positioner cooperates with the deep welding robot to weld the workpiece, the workpiece needs to be fixed on the rotating mechanism of the positioner with a clamp. As the rotating mechanism in the positioner runs, the fixed workpiece will be actively assisted in rotation. However, this process will hinder the coordinated welding of multiple workpieces.

[0052] Therefore, the device can replace the existing positioner to change the welding of a single workpiece into multiple workpieces. When the first weldment 410 and the second weldment 420 are stacked and compressed by the booster gasket 550 and the base 340, the first weldment 410 and the second weldment 420 compressed by the two tightening rods 530 will not interfere with the delivery of the welding rod, and at the same time, the ports of multiple workpieces connected can be exposed to the working environment. At this time, the ports of the first weldment 410 and the second weldment 420 that are compressed can be calibrated and supported by the foot 230. As the base 310 of the device is driven, the pressed first weldment 410 and the second weldment 420 can be welded without hindrance by the welding rod. At this time, the device can clamp multiple workpieces and cooperate with the welding robot, and can also calibrate the ports of the multiple workpieces after bonding, so as to improve the compressive strength of the workpieces to the welding robot.

[0053] Embodiment 2:

[0054] Combination Figure 2-Figure 9 As shown, on the basis of the first embodiment, the flip mechanism 100 also includes a fixed shaft 110 movably installed in the rocker arm 121, a fixed gear shaft 130 installed on the fixed shaft 110, a sleeve 140 installed inside the rocker arm 121, a deflection gear shaft 150 installed inside the sleeve 140, a chain 160 transmission-connected to the deflection gear shaft 150, and two first bearings 170 installed inside the rocker arm 121.

[0055] The rotation-assisting assembly 120 further includes two first clamps 122 fixedly mounted in the grooves on the inner side of the rocker arm 121, a first gear shaft 123 movably mounted inside the two first clamps 122, two second clamps 124 fixedly mounted inside the rocker arm 121, a second gear shaft 125 movably mounted inside the two second clamps 124, and a third clamp 126 fixedly mounted inside the rocker arm 121. There are two third clamps 126, and hydraulic components 127 are mounted inside the two third clamps 126.

[0056] A chuck is fixedly mounted on the outer end of the hydraulic sub-rod in the hydraulic component 127 .

[0057] The rocker arm 121 is in an L-shaped structure as a whole, and two symmetrically distributed slideways are provided on the outside of the rocker arm 121 , and the two slide plates on the top of the chassis 180 are adapted to penetrate into the two slideways.

[0058] The fixed shaft 110 and the fixed gear shaft 130 are used to provide a support platform. When the motor 190 is started and running, the gear plate on the internal transmission shaft will assist the gear plate 320 to rotate in advance. When the base 310 and the gear plate 320 have completed their rotation, the hydraulic sub-rod in the hydraulic component 127 will drive the chassis 180 to contract until the gear plate in the motor 190 engages with the second gear shaft 125, and then transmits the first clamp 122. At this time, the first clamp 122 will transmit the chain 160 and the deflection gear shaft 150 until the rocker arm 121 is compressed and rotates along the outside of the fixed shaft 110. At this time, the device can use an independent function to provide lifting and lowering regulation for the welding of the workpiece.

[0059] Embodiment three:

[0060] Combination Figure 2-Figure 8 As shown, on the basis of the first embodiment, the vertical rod 210 and the reinforcement ring 220 are both made of stainless steel, and the reinforcement ring 220 is installed with symmetrically distributed sleeves at both ends away from the two vertical rods 210;

[0061] The first rotating ring 520 and the second rotating ring 540 are both provided with symmetrically distributed raised end plates on their exteriors, and a nut is provided on the threaded section at the bottom of the tightening rod 530 .

[0062] By pre-fixing the other two vertical rods 210 on the top of the rocker arm 121 and the reinforcement ring 220 on the top of the two vertical rods 210, the reinforcement ring 220 can be located outside the gap between the first weldment 410 and the second weldment 420. The nut on the foot 230 rotates, and the arc-shaped end surface at the inner end of the foot 230 will eventually be pressed against the outside of the ports of the first weldment 410 and the second weldment 420. As the pressure increases, the ports of the first weldment 410 and the second weldment 420 can be calibrated and constrained. At this time, the welding of the first weldment 410 and the second weldment 420 can be supported sufficiently stably. At the same time, the two tightening rods 530 can also be reinforced and fixed, thereby preventing the first weldment 410 and the second weldment 420 from shaking due to the increase in height.

[0063] Embodiment 4:

[0064] Combination Figure 1-Figure 9 As shown, based on the first embodiment, the rotating assembly 300 further includes a locking bolt 350 disposed in the base 340 and penetrating into the interior of the base 310 , and a top cover 330 installed on the top of the base 310 and located at the bottom of the base 340 .

[0065] A nut is disposed on the threaded end rod at the bottom of the base 310 , and the thread is pressed tightly against the bottom of one of the first bearings 170 .

[0066] The assembly to be welded 400 includes a first weldment 410 disposed in the annular groove at the top of the base 340 and a second weldment 420 disposed on the top of the first weldment 410 and located in the groove at the bottom of the booster gasket 550 .

[0067] The base 310 is locked on the two first bearings 170 using nuts. At this time, the bottom end surface of the base 310 will fit on the rocker arm 121. As the motor 190 runs, its internal transmission shaft will cooperate with the gear plate to drive the gear plate 320 and the base 310. At this time, the base 340 set on the top of the base 310 can drive the first weldment 410 and the second weldment 420 to rotate stably after being clamped, thereby providing a multi-angle welding platform for the robot.

[0068] The working principle and use process of the present invention are as follows: the main sealing ring 510 is fixedly installed on the top of the base 340 by using multiple bolts in advance, and the first rotating ring 520 is movably installed between the main sealing ring 510 and the base 340, and then the secondary sealing ring 560 is fixedly installed on the bottom of the boost washer 550 by using bolts. At this time, the second rotating ring 540 will be located between the boost washer 550 and the secondary sealing ring 560, and the two tightening rods 530 are fixedly installed in the two raised end plates outside the second rotating ring 540, and the combined base 310 is assembled in the two first bearings 170 through nuts. At this time, the bottom of the base 310 is attached to the top of the rocker arm 121, and the gear plate 320 installed on the base 310 is meshed with the gear plate on the transmission shaft in the motor 190;

[0069] When in use, after the operator places the first weldment 410 on the top of the base 340, the second weldment 420 is stacked on the top of the first weldment 410, and then the threaded sections at the bottom of the two tightening rods 530 are passed through the two raised end plates outside the first rotating ring 520 and locked with nuts. At this time, the ports of the first weldment 410 and the second weldment 420 that fit each other are located on the foot 230, and the arc-shaped end surface of the reinforcing ring 220 will calibrate the tightened ports of the first weldment 410 and the second weldment 420. When the welding robot controls the electrode to approach the first At the ports of weldment 410 and second weldment 420, as the welding rod performs deep welding operation on the port gap, the gear plate 320 driven by the motor 190 will drive the base 310 and the base 340 to rotate, and the first weldment 410 and the second weldment 420 that are clamped will also rotate accordingly. At this time, the device can cooperate with the welding operation of the robot arm to assist the rotation of the workpiece, and in the process of assisting the rotation, the current single workpiece welding can be changed to multi-workpiece collaborative welding, thereby ensuring that the workpiece can be raised and lowered and rotated without interfering with the multi-angle welding operation of the welding robot.

[0070] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
