Description

Technical Field

[0001] This invention belongs to the field of component welding technology, and in particular relates to a welding processing device for structural components of new energy vehicles. Background Technology

[0002] With the rapid development of the new energy vehicle industry, the requirements for vehicle body lightweighting, structural strength and manufacturing precision are increasing. In the production and manufacturing process of new energy vehicles, a large number of irregular structural parts are involved, such as battery pack brackets, chassis connectors and body reinforcing ribs, which require welding processes. These parts often require precise welding of a central main workpiece and multiple peripheral branch workpieces at different circumferential angles to ensure the overall rigidity and safety of the vehicle structure.

[0003] For welding of structural components in new energy vehicles, the main methods used are general-purpose welding fixtures with multi-axis positioners or manual operation. In practice, when performing circumferential multi-point welding, the alignment of peripheral components and adjustment of the fixture's posture are necessary, which can easily lead to positioning errors, affecting the consistency of welding quality. Furthermore, it is difficult to ensure that the extension length of each branch component is completely consistent with the welding end face, resulting in defects such as burn-through, incomplete welds, or poor appearance after welding. Therefore, we provide a welding processing device for structural components in new energy vehicles to solve the above-mentioned technical problems. Summary of the Invention

[0012] The invention is further configured such that: a transmission groove is formed on the upper surface of the welding control platform; a transmission screw is rotatably connected inside the transmission groove; a welding support platform is provided on the upper surface of the welding control platform; an extension slider that slides in cooperation with the transmission groove is fixedly connected to the lower surface of the welding support platform; the extension slider and the transmission screw are threadedly engaged; two sealing grooves are symmetrically formed on the upper surface of the welding support platform; two sealing barrier plates are symmetrically arranged on the upper surface of the welding support platform; the sealing barrier plates slide in cooperation with the corresponding sealing grooves; and a first transmission rack is fixedly connected to one side of the sealing barrier plate via a first bracket.

This can maintain a stable clamping position, facilitating the stability of subsequent welding operations. At the same time, it effectively avoids the interference of welding spatter on non-welding areas. Furthermore, the clamping action and workpiece feeding are completed in tandem, improving the automation and reliability of loading and positioning.

[0016] 3. By setting up a limiting support component, the present invention utilizes a limiting adjustment groove composed of inclined, horizontal and vertical sliding grooves in cooperation with the transmission cross column, combined with the limiting adjustment linkage to differentially control the first lifting plate and the second lifting plate, to achieve a continuous action of automatic centering and clamping of the upper and lower limiting plates during the rising process and automatic release during the falling process. It can provide stable rotational support and circumferential limiting for parts during the welding stage, and can quickly release the clamping during the loading and unloading stage, thus taking into account both the rigidity of workpiece fixation during welding and the convenience of operation.

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] For a specific implementation example, please refer to Implementation Example 1. Figure 1-10 The present invention is a welding processing device for structural parts of new energy vehicles, including a limiting support component 1 fixedly installed on the upper surface of the workbench. Specifically, a plurality of feeding and pushing components 2 are fixedly connected to the periphery of the limiting support component 1, and welding adjustment components 3 corresponding one-to-one with the feeding and pushing components 2 are provided on the upper surface of the limiting support component 1. The welding adjustment components 3 and the limiting support component 1 slide together.

[0031] Furthermore, the limiting support component 1 is used to limit the position of the component, while rotating the component to adjust the welding at different positions. The feeding and pushing component 2 is used to feed and push the parts to be welded. The welding adjustment component 3 is used to limit the initial welding position of the parts pushed by the feeding and pushing component 2, and can adjust the angle of the limited parts.

[0032] The operation process of this embodiment is as follows: The structural components of the new energy vehicle to be welded are placed on the feeding and pushing component 2 and the limiting support component 1 respectively. The feeding and pushing component 2 is activated, accurately pushing the components to the designated positions of the corresponding welding adjustment component 3. The welding adjustment component 3 limits the position of the components while keeping the exposed parts of the components consistent, which facilitates subsequent welding adjustments. At the same time, the limiting support component 1 starts to work, which stably limits the position of the components on the limiting support component 1 to prevent displacement during subsequent welding. Then, the limiting support component 1 drives the limited components to rotate. When the welding position of the components on the limiting support component 1 is aligned with the corresponding welding adjustment component... When the components on the 3rd and 4th octagonal support components are aligned, the welding adjustment component 3 adjusts the angle of the components according to the welding position until the welding end faces the component on the limiting support component 1. The welding adjustment component 3 is then controlled to slide radially along the surface of the limiting support component 1 until the welding end of the component on the welding adjustment component 3 is in close contact with the peripheral side of the component on the limiting support component 1. The welding equipment is then used to weld the two components. After welding at one position is completed, the limiting support component 1 drives the component to rotate and adjust again so that the component on the limiting support component 1 is aligned with the corresponding welding adjustment component 3, and the next round of welding operation is performed. This cycle is repeated to achieve efficient and precise welding processing of structural components of new energy vehicles.

[0033] For a specific embodiment two, please refer to Figure 1-10Based on the specific embodiment 1, specifically, the limiting support assembly 1 includes a supporting upright tube 101 fixedly connected to the upper surface of the workbench. A limiting adjustment groove 102 is formed on the inner wall of the supporting upright tube 101. The limiting adjustment groove 102 is composed of an inclined groove, a horizontal groove, and a vertical groove connected in sequence. A hollow adjusting frame 103 is fixedly connected to the upper surface of the supporting upright tube 101. A radial adjusting ring 104 is rotatably connected inside the hollow adjusting frame 103, and a transmission external gear is fixedly connected to the circumferential side of the radial adjusting ring 104. A radial gear 106 is rotatably connected to the bottom of the hollow adjustment frame 103. The radial gear 106 meshes with the transmission external gear ring 105. A control motor is fixedly installed on the lower surface of the hollow adjustment frame 103. The output shaft of the control motor is fixedly connected to the radial gear 106. The radial control ring 104 has radial drive slides 107 that correspond one-to-one with the welding adjustment components 3 on its surface. The hollow adjustment frame 103 has radial transmission slides 108 that correspond one-to-one with the radial drive slides 107 on its surface.

[0034] Furthermore, a limit plate 109 is coaxially arranged inside the hollow adjustment frame 103. A support column is fixedly connected to the lower surface of the limit plate 109. A transmission cross column 110 is fixedly connected to the periphery of the support column. The transmission cross column 110 and the limit adjustment slide groove 102 are in sliding fit. An adjustment external gear ring 111 is fixedly connected to the periphery of the support column. A limit support plate 112 is rotatably connected to the lower surface of the support column. A limit gear 113 that meshes with the adjustment external gear ring 111 is rotatably connected to the upper surface of the limit support plate 112. A limit motor is fixedly installed on the lower surface of the limit support plate 112. The output shaft of the limit motor is fixedly connected to the limit gear 113. A limit telescopic rod and a limit spring are fixedly connected between the limit support plate 112 and the worktable.

[0035] Furthermore, the limiting support assembly 1 also includes a limiting support plate 114 fixedly connected to the upper surface of the hollow adjusting frame 103 via a supporting upright plate. A limiting opening is formed on the surface of the limiting support plate 114, and a limiting transmission disc 115 is rotatably connected inside the limiting opening. A limiting control rod 116 is rotatably connected to the upper surface of the limiting transmission disc 115 via an ear plate. Two limiting transmission slides 117 are symmetrically formed on the surface of the limiting control rod 116. A first lifting plate 118 is slidably disposed through the surface of the limiting transmission disc 115. The second lifting plate 119, the first lifting plate 118, and the second lifting plate 119 are all fixedly connected to one side of a lifting transmission rod. The lifting transmission rod is slidably engaged with the corresponding limiting transmission slide 117. One end of the first lifting plate 118 is fixedly connected to a limiting upper plate 120. The upper surface of the limiting lower plate 109 and the lower surface of the limiting upper plate 120 are both made of elastic material, which facilitates the position limitation of the parts. The second lifting plate 119 slides through the limiting upper plate 120 and is fixedly connected to the limiting lower plate 109.

[0036] The operation process of this embodiment is as follows: When performing component welding, the new energy vehicle structural component to be welded is first placed on the lower limiting plate 109. The limiting motor is started to drive the limiting gear 113 to rotate. Under the meshing action of the limiting gear 113 and the regulating external gear ring 111, the regulating external gear ring 111 drives the supporting column to rotate, thereby causing the transmission horizontal column 110 to slide along the trajectory of the limiting regulating slide groove 102. Under the sliding cooperation between the transmission horizontal column 110 and the limiting regulating slide groove 102, when the transmission horizontal column 110 slides along the inclined slide groove of the limiting regulating slide groove 102, the transmission horizontal column 110 drives the supporting column and the limiting... The lower plate 109 moves upward synchronously, and the limiting telescopic rod and the limiting spring are stretched synchronously, thereby driving the parts to be welded to move upward synchronously. Simultaneously, the lower plate 109 drives the second lifting plate 119 to move upward synchronously. Under the sliding engagement of the lifting transmission rod on the second lifting plate 119 and the corresponding limiting transmission slide 117, the limiting control linkage 116 rotates. Under the sliding engagement of the other limiting transmission slide 117 and the lifting transmission rod on the first lifting plate 118, the first lifting plate 118 moves downward, thereby driving the upper plate 120 to move downward. When the transmission column 110 moves to the limiting control slide... At the intersection of the inclined and horizontal sliding grooves of groove 102, the upper limiting plate 120 is in close contact with the component. Under the combined action of the upper limiting plate 120 and the lower limiting plate 109, the position of the component is limited, ensuring that the component will not shift during welding, providing a stable foundation for subsequent precise welding. After the component completes the limiting operation, during component welding, the limiting gear 113 is controlled to rotate, and the external gear ring 111 is adjusted to drive the support column to rotate. Under the clamping and restriction of the upper limiting plate 120 and the lower limiting plate 109, the restricted component is rotated and adjusted, facilitating zero-load adjustments at different positions of the component. During the component welding operation, the transmission column 110 moves along the horizontal slide section of the limit adjustment slide 102 until the welding operation of the component is completed. The transmission column 110 rotates to the intersection of the horizontal slide and the vertical slide of the limit adjustment slide 102. As the transmission column 110 moves, under the elastic recovery action of the limit spring, the transmission column 110 slides down along the vertical slide. During this process, the lower limit plate 109 moves down, the limit adjustment linkage 116 rotates in the opposite direction, and the first lifting plate 118 drives the upper limit plate 120 to move up. The component restriction is lifted, making it convenient to take out and transfer the welded component.

[0037] For a specific embodiment three, please refer to Figure 1-10Based on specific embodiments one and two, specifically, the feeding and pushing component 2 includes a feeding support frame 201 fixedly connected to the periphery of the hollow adjusting frame 103. Two feeding rollers are symmetrically fixedly connected between the two inner sidewalls of the feeding support frame 201, and the two feeding rollers are connected by a feeding conveyor belt 202. A drive source is fixedly installed on one side of the feeding support frame 201, and the output end of the drive source is fixedly connected to the corresponding feeding roller. A feeding guide frame 203 is fixedly connected to the upper surface of the feeding support frame 201. A feeding control table 204 is fixedly connected to the upper surface of the feeding support frame 201. A feeding guide groove is opened at the top of the feeding control table 204. A guide slide rod 205 is fixedly connected between the two inner side walls of the feed guide groove. A guide slider is slidably arranged on the periphery of the guide slide rod 205. A feed reset spring 206 is fixedly connected between the guide slider and the feed guide groove. The feed reset spring 206 is sleeved on the periphery of the guide slide rod 205. A push transmission plate 207 is fixedly connected to the lower surface of the guide slider through an electric telescopic rod. The lower end of the push transmission plate 207 has a rough material structure. When the push transmission plate 207 is in contact with the feed conveyor belt 202, it moves synchronously with the feed conveyor belt 202. A feed push plate 208 is fixedly connected to one side of the push transmission plate 207 through an extension crossbar.

[0038] Furthermore, the welding adjustment assembly 3 also includes a slidingly arranged adjustment support platform. An adjustment transmission column 301 is fixedly connected to the lower surface of the adjustment support platform. The adjustment transmission column 301 is slidably engaged with the corresponding radial drive slide 107 and radial drive slide 108. A transmission sector worm gear 302 is fixedly connected to the upper surface of the adjustment support platform. Two arc-shaped support platforms 303 are symmetrically fixedly connected to the upper surface of the adjustment support platform. A welding control platform 304 is slidably arranged between the two arc-shaped support platforms 303. A drive worm 305 is rotatably connected between the welding control platform 304 and its two inner sidewalls. A drive motor is fixedly installed on one side of the welding control platform 304. The output shaft of the drive motor is fixedly connected to the drive worm 305. The drive worm 305 is adapted to the transmission sector worm gear 302.

[0039] Furthermore, the upper surface of the welding control table 304 is provided with a transmission groove, and a transmission screw 306 is rotatably connected inside the transmission groove. A transmission motor is fixedly installed on one side of the welding control table 304, and the output shaft of the transmission motor is fixedly connected to the transmission screw 306. A welding support table 307 is provided on the upper surface of the welding control table 304, and an extension slider that slides in cooperation with the transmission groove is fixedly connected to the lower surface of the welding support table 307. The extension slider is threadedly engaged with the transmission screw 306. Two sealing grooves are symmetrically provided on the upper surface of the welding support table 307, and two sealing barrier plates 308 are symmetrically provided on the upper surface of the welding support table 307. The sealing barrier plates 308 slide in cooperation with the corresponding sealing grooves, and a first transmission rack 309 is fixedly connected to one side of the sealing barrier plate 308 through a first bracket.

[0040] The upper surface of the welding support platform 307 is symmetrically provided with limit guide grooves. Limit clamps 310 are slidably installed inside the limit guide grooves. A transverse spring is fixedly connected between the limit clamps 310 and the limit guide grooves. A magnet is fixedly installed on one side of the limit clamps 310. An electromagnet is fixedly installed on the inner wall of the limit guide groove. In the initial state, the electromagnet is connected to an external power source, and the electromagnet and the magnet attract each other magnetically, and the transverse spring is in a stretched state. A second transmission rack 311 is fixedly connected to the other side of the limit clamps 310 through a second bracket. Two limit adjustment gears 312 are symmetrically rotatably connected to the upper surface of the welding support platform 307. The limit adjustment gears 312 mesh with the corresponding first transmission rack 309 and second transmission rack 311.

[0041] The operation process of this embodiment is as follows: The parts to be welded are placed on the feeding conveyor belt 202, and the drive source is started to drive the feeding roller to rotate. Under the connection of the feeding conveyor belt 202, the feeding conveyor belt 202 moves in a cycle, driving the parts to move horizontally for transmission. When the parts move to one end of the feeding push plate 208, the electric telescopic rod is started to drive the push transmission plate 207 to move downward until the push transmission plate 207 is in contact with the upper surface of the feeding conveyor belt 202. Under the action of friction, the push transmission plate 207 will move synchronously with the movement of the feeding conveyor belt 202. At this time, the guide slider slides on the guide slide rod 205 and pulls... The loading reset spring 206 extends; during the movement of the pushing transmission plate 207, the extending crossbar drives the loading push plate 208 to move together. The loading push plate 208 pushes the parts located on the loading conveyor belt 202, further ensuring that the parts can be accurately and stably transported to the corresponding position of the welding adjustment component 3. When the parts are transported to the position, the electric telescopic rod retracts, driving the pushing transmission plate 207 to move upward and disengage from the loading conveyor belt 202. The loading reset spring 206 resets under its own elastic force, pulling the guide slider and the pushing transmission plate 207 back to the initial position, waiting for the next loading operation.

[0042] As the feeding pusher plate 208 moves horizontally, the parts are pushed towards the corresponding welding adjustment assembly 3. Guided by the feeding guide frame 203, the parts move between the two limiting clamps 310 until the welding end of the parts is in contact with the two sealing barrier plates 308. The external power supply of the electromagnet is disconnected, and the magnetic attraction between the electromagnet and the corresponding magnetic magnet disappears. Under the elastic recovery action of the transverse spring, the limiting clamps 310 slide along the trajectory of the limiting guide groove. The two limiting clamps 310 move synchronously and move closer to each other until the limiting clamps 310 are in close contact with the parts, thus clamping and limiting the parts. At the same time, as the limiting clamps 310 move, the second transmission rack 311... Synchronous horizontal movement occurs as the second transmission rack 311 and the first transmission rack 309 mesh with the corresponding limit adjustment gear 312. The limit adjustment gear 312 rotates, and the first transmission rack 309 drives the corresponding sealing barrier plate 308 to move horizontally. The two sealing barrier plates 308 move synchronously away from each other, exposing the welding end of the component. The transmission motor is started, driving the transmission screw 306 to rotate. Under the threaded engagement of the transmission screw 306 and the extension slider, the extension slider moves along the transmission groove trajectory, thereby causing the welding support table 307 to move synchronously. Driven by the welding support table 307, the component moves to the end of the welding control table 304 near the axis of the limit support assembly 1.

[0043] Before welding, adjust the orientation of the welding ends of the components on the welding adjustment assembly 3 according to the welding position requirements. Start the drive motor to drive the drive worm 305 to rotate. Under the cooperation between the drive worm 305 and the transmission sector worm wheel 302, the welding control table 304 moves along the arc trajectory of the arc support table 303, thereby driving the components to adjust their angle until the welding ends of the components are aligned with the welding position. Start the control motor to drive the radial gear 106 to rotate. Under the meshing action of the radial gear 106 and the transmission external gear ring 105, the transmission external gear ring 105 drives the radial gear 106 to rotate. Rotating towards the control ring 104, under the sliding cooperation of the adjustment transmission column 301 with the corresponding radial control ring 104 and radial transmission slide 108, the adjustment transmission column 301 moves along the trajectory of the radial control ring 104 and radial transmission slide 108, and the adjustment support platform moves radially closer to the axis position of the hollow adjustment frame 103, and then the parts on the welding adjustment assembly 3 move synchronously until the parts on the welding adjustment assembly 3 are in contact with the parts on the limit support assembly 1. The two are welded using external welding equipment. This cycle is repeated to achieve welding between the parts.
