Description

Technical Field

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

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

[0003] At present, when a positioner cooperates with a deep welding robot to weld workpieces, 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 fixture, the fixture independently fixed on the rotating mechanism cannot meet the requirements of the coordinated welding of multiple workpieces. At the same time, specific fixtures will also hinder the welding operation.

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

[0008] The flipping mechanism includes a rotation-assisting component;

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

[0010] The calibration assembly includes 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 mounted in the middle of the reinforcement ring;

[0011] The rotating assembly includes a gear plate driven by a motor, a base installed in the gear plate, and a base arranged on top of the base, wherein a ring groove is formed in the rotating plate on the top of the base;

[0012] The welding piece clamping mechanism comprises a main sealing ring mounted on the top of the base, a first rotating ring movably mounted on the outside of the base, two tightening pull rods mounted in the first rotating ring, a second rotating ring fixedly mounted on the top of the two tightening pull rods, a booster washer arranged on the top of the second rotating ring, and a vice sealing ring mounted on the bottom of the booster washer.

[0013] In a preferred example, the present application can be further configured as: the turnover mechanism further comprises a fixed shaft movably mounted in the rocker arm, a fixed gear shaft mounted on the fixed shaft, a shaft sleeve mounted in the inside of the rocker arm, a deflection gear shaft mounted in the inside of the shaft sleeve, a chain transmission connected to the deflection gear shaft, and two first bearings mounted in the inside of the rocker arm.

[0014] In a preferred example, the present application can be further configured as: the turnover assembly further comprises two first clamps fixedly mounted in the recess on the inside of the rocker arm, a first gear shaft movably mounted in the inside of the two first clamps, two second clamps fixedly mounted in the rocker arm, and a second gear shaft movably mounted in the inside of the two second clamps.

[0015] In a preferred example, the present application can be further configured as: the turnover assembly further comprises two third clamps fixedly mounted in the rocker arm, and hydraulic components mounted in the inside of the two third clamps.

[0016] The outer end of the hydraulic sub-rod in the hydraulic component is fixedly mounted with a chuck.

[0017] In a preferred example, the present application can be further configured as: the rocker arm is in an overall L-shaped structure, and two symmetrically distributed slideways are formed on the outside of the rocker arm, and the two sliding plates on the top of the case are adapted to penetrate into the two slideways.

[0018] In a preferred example, the present application can be further configured as: the vertical rods and the reinforcing ring are made of stainless steel material, and the reinforcing ring is mounted with symmetrically distributed sleeves away from the two ends of the two vertical rods.

[0019] In a preferred example, the present application can be further configured as: the rotating assembly further comprises a locking bolt arranged in the base and penetrating into the inside of the base, and a top cover mounted on the top of the base and located at the bottom of the base.

[0020] In a preferred example, the present application can be further configured as: a nut is arranged on the threaded end rod at the bottom of the base, and is tightly pressed on the bottom of one of the first bearings.

When the deep welding robot controls the welding rod to approach the multiple workpieces, the multiple workpieces clamped can expose a gap sufficient for the welding rod to extend into. At the same time, when the welding rod performs multi-angle welding on the multiple workpieces, the device will not cause any obstruction to the welding of the multiple workpieces by the welding rod.

[0025] 2. The present invention arranges a calibration component on a specific fixture for clamping multiple workpieces. 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 solutions and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other without conflict.

[0042] It is to be understood that these descriptions are illustrative 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 with reference to the accompanying drawings.

[0044] Example 1:

[0045] Combine Figures 1-9 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 disposed outside the component to be welded 400, a rotating component 300 mounted on the weldment clamping mechanism 500, a turning mechanism 100 movably mounted on the rotating component 300, and a calibration component 200 mounted on the turning mechanism 100 and the weldment clamping mechanism 500;

[0046] The turning 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 mounted in the gear plate 320, and a base 340 disposed on top of the base 310. An annular groove is formed in the rotating disk on 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 a positioner is used in conjunction with a deep welding robot to weld a workpiece, the workpiece needs to be fixed to the rotating mechanism of the positioner using a fixture. As the rotating mechanism inside the positioner operates, 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 pressed by the booster gasket 550 and the base 340, the first weldment 410 and the second weldment 420 pressed 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 pressed can be calibrated and supported by the pads 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 to improve the compressive strength of the workpieces to the welding robot.

[0053] Example 2:

[0054] Combine Figure 2-Figure 9 As shown, based on 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 grooves inside the rocker arm 121, a first gear shaft 123 movably mounted inside the two first clamps 122, two second clamps 124 fixedly mounted in the rocker arm 121, a second gear shaft 125 movably mounted inside the two second clamps 124, and a third clamp 126 fixedly mounted in the rocker arm 121. There are two third clamps 126, and hydraulic components 127 are installed 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 an L-shaped structure as a whole, and two symmetrically distributed slides are opened on the outside of the rocker arm 121, and the two slides on the top of the chassis 180 are adapted to pass through the two slides.

[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 its 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 pressurized 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 control for the welding of the workpiece.

[0059] Example 3:

[0060] Combine Figure 2-Figure 8 As shown, based on 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 fixing 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. When the nut on the foot 230 rotates, the arc-shaped end surface of 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 with sufficient stability. 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] Example 4:

[0064] Combine Figures 1-9 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 mounted on the top of the base 310 and located at the bottom of the base 340 .

[0065] A nut is provided on the threaded end rod at the bottom of the base 310 , and the thread fits 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 top of the first weldment 410 and located in the groove at the bottom of the pressurizing washer 550 .

[0067] Use nuts to lock the base 310 on the two first bearings 170. 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 application: a plurality of bolts are used to fix and install the main sealing ring 510 on the top of the base 340, and the first rotating ring 520 is movably installed between the main sealing ring 510 and the base 340, then the bolt is used to fix and install the secondary sealing ring 560 on the bottom of the booster gasket 550, at this time the second rotating ring 540 is located between the booster gasket 550 and the secondary sealing ring 560, and the two tightening pull rods 530 are fixedly installed in the two protruding end plates outside the second rotating ring 540, and the combined base 310 is assembled in the two first bearings 170 by nuts, at this time the bottom of the base 310 is attached to the top of the rocker arm 121, and the gear disc 320 installed on the base 310 is engaged with the gear piece on the transmission shaft in the motor 190.

[0069] In use, when the operator places the first welding part 410 on the top of the base 340, then stacks the second welding part 420 on the top of the first welding part 410, then inserts the threaded section at the bottom of the two tightening pull rods 530 into the two protruding end plates outside the first rotating ring 520, and locks it with a nut, at this time the ports of the first welding part 410 and the second welding part 420 attached to each other are located on the foot 230, and the arc-shaped end face of the reinforcing ring 220 can align the ports of the first welding part 410 and the second welding part 420 after tightening, when the welding robot controls the welding rod to approach the ports of the first welding part 410 and the second welding part 420, as the welding rod performs deep welding on the port gap, the gear disc 320 driven by the motor 190 will drive the base 310 and the base 340 to rotate, and the first welding part 410 and the second welding part 420 under compression will also rotate, at this time the device can assist the workpiece rotation in cooperation with the welding work of the mechanical arm, and in the process of assisting the rotation, the single workpiece welding can be changed to multi-workpiece cooperative welding, so that the workpiece can be lifted and rotated without interfering with the multi-angle welding work of the welding robot.

[0070] Although the embodiments of the present application have been shown and described, those skilled in the art can understand that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and purposes of the present application, and the scope of the present application is defined by the claims and their equivalents.
