Description

Technical Field

[0001] This utility model relates to the field of laser welding, and in particular to a flipping platform for quality inspection of lap-welded plates. Background Technology

[0002] In the field of laser welding, products that require lap welding are frequently encountered, such as honeycomb jacket structures. A honeycomb jacket structure refers to two plates that are overlapped and then welded together. After welding, high-pressure water is used to inflate the lap-welded plates. These types of lap-welded plates are used in heat dissipation or heat conduction applications.

[0003] However, before bulging, the welding quality of the plates needs to be inspected. The inspection scope includes whether there are defects in the welds on both the top and bottom sides. The inspection process involves inspecting one side first, and then flipping the welded plates over to inspect the other side. Welded parts are usually quite large. If they are flipped manually, the efficiency is low and there are certain safety hazards. Currently, for such large and heavy welded products, they are mostly flipped by overhead crane. This flipping method saves manpower, but the safety factor is not reduced, and the flipping efficiency is not high, which affects the product inspection efficiency. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a flipping platform for inspecting the quality of welded plates, which can facilitate the inspection of weld quality of welded plates.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] A flipping platform for quality inspection of lap-welded plates includes a base. A main shaft bearing seat and a driven shaft bearing seat are respectively provided at the left and right ends of the base. A rotatable flipping table is provided between the main shaft bearing seat and the driven shaft bearing seat. One end of the flipping table is fixedly connected to a drive shaft movably disposed within the main shaft bearing seat, and the other end is fixedly connected to a driven shaft movably disposed within the driven shaft bearing seat. A servo reduction mechanism is provided on the outer side of the main shaft bearing seat. The power output end of the servo reducer is connected to the drive shaft, enabling it to drive the drive shaft to rotate clockwise or counterclockwise. The flipping table has a rectangular structure. A quick-clamping device for clamping and fixing the lap-welded plates is provided on the top surface near one of its long sides, and a movable clamping device for limiting the edges of the lap-welded plates is provided near the other long side.

[0007] Furthermore, the tilting table has a rectangular frame structure, and its bottom two sides are fixedly connected to the drive shaft and the driven shaft respectively through connecting flanges. Inside the tilting table, there are several longitudinally arranged support ribs arranged in an array along its length direction. The front and rear ends of the support ribs are fixedly welded to the front and rear long sides of the tilting table. The movable clamping device is fixedly arranged on the support ribs.

[0008] Furthermore, the quick clamping device includes a support frame, a quick clamp is provided on one side of the top of the support frame, a stop is provided on one side of the quick clamp, and a positioning groove is provided on one end of the stop corresponding to the center of the flipping table.

[0009] Furthermore, the movable clamping device includes a slide rail and a slider that slides with the slide rail. A clamping block is fixed on the top of the slider. A slot is provided on one end of the clamping block corresponding to the center of the flip table. A threaded hole with vertical connection is provided on the top of the slider located behind the clamping block. The lower end of the threaded hole corresponds to the top of the slide rail, and a set screw that engages with its thread is provided inside.

[0010] Furthermore, the top of the support rib is fixed with a plurality of longitudinally rolling rollers and a plurality of transversely rolling rollers along its front-to-back length direction, and the longitudinal rollers and transverse rollers are arranged at intervals.

[0011] Furthermore, a reinforcing rib of the same length is welded to the bottom of the supporting rib.

[0012] Furthermore, the quick clamping device and the movable clamping device are each provided in multiple sets, and the multiple sets of the movable clamping device and the quick clamping device are arranged side by side at equal intervals along the length direction of the front and rear sides of the base.

[0013] Furthermore, two polyurethane pads are symmetrically arranged on the inner side of the main spindle bearing housing, located below the drive shaft, with the drive shaft as the center. The polyurethane pads are mounted on the main spindle bearing housing by a fixing seat, and the two polyurethane pads are inclined outward, forming an "eight" shape.

[0014] Compared with the prior art, the advantages of this utility model are: this flipping platform for quality inspection of lap-welded plates facilitates the inspection of weld quality of lap-welded plates. The lap-welded plates are fixed on the flipping platform, and the flipping platform can drive the lap-welded plates fixed to it to flip over, so that the front and back of the lap-welded plates can be flipped over and presented to the inspection personnel, reducing the uncontrollable danger factors caused by the overturning of the crane, improving the safety of the flipping, and improving the inspection efficiency.

[0030] Example

[0031] Please refer to the instruction manual attached. Figure 1 and 2 As shown, the instruction manual is attached. Figure 1 and 2 The diagram shows a flipping platform for quality inspection of lap-welded plates according to this utility model. It is used for flipping lap-welded plates to facilitate the inspection of weld seams. The flipping platform includes a base 1. (See attached instruction manual.) Figure 3 and 5 As shown, the base is constructed from welded square tubing with a triangular end face. A main shaft bearing seat 11 and a driven shaft bearing seat 12 are respectively located at the left and right ends of the base 1. Bearings are installed within both the main shaft bearing seat 11 and the driven shaft bearing seat 12. A rotatable tilting table 3 is positioned between the main shaft bearing seat 11 and the driven shaft bearing seat 12. The tilting table 3 has a rectangular structure, specifically a rectangular frame structure, and is located above the top of the base 1. One end of the tilting table 3 is fixedly connected to the drive shaft 13, which is movably disposed within the main shaft bearing seat 11, and the other end is fixedly connected to the driven shaft 14, which is movably disposed within the driven shaft bearing seat 12. The drive shaft 13 is disposed within the bearing of the main shaft bearing seat 11 and can rotate relative to the main shaft bearing seat 11. The driven shaft 14 is disposed within the bearing of the driven shaft bearing seat 12 and can rotate relative to the driven shaft bearing seat 12. To connect the two ends of the tilting table 3 to the drive shaft 13 and the driven shaft 14 respectively... The bottom sides of the tilting table 3 are fixedly connected to the drive shaft 13 and the driven shaft 14 respectively via connecting flanges 15. The connecting flanges 15 have an inverted L-shaped structure, with their vertical surfaces fixedly connected to the drive shaft 13 and the driven shaft 14, and their horizontal surfaces fixedly connected to the bottom of the tilting table 3. Inside the tilting table 3, i.e., within its square frame structure, there are several longitudinally arranged support ribs 31 arranged along the length of the front and rear sides of the tilting table 3. The front and rear ends of the support ribs 31 are respectively fixedly welded to the long sides of the front and rear sides of the tilting table 3, which strengthens the structure of the tilting table 3. It should be noted that the distribution spacing of the support ribs 31 matches the weld spacing of the lapped plates, ensuring that the welds on the back of the lapped plates can be well observed while ensuring the overall structural strength. To improve the support strength of the support ribs 31, reinforcing ribs 311 of the same length are fixedly welded to the bottom of the support ribs 31. The reinforcing ribs 311 are arranged vertically, making the support ribs 31 less prone to bending and deformation, and providing better support. See the appendix of the instruction manual. Figure 1 and 8As shown, to facilitate the horizontal movement of the lap-welded plates on the top of the horizontally positioned tilting table 3, and to allow for easy position adjustment, each of the supporting ribs 31 has multiple longitudinally rolling rollers 6 and multiple laterally rolling rollers 7 fixed to its top along its front-to-back length. The longitudinally rolling rollers 6 and the laterally rolling rollers 7 are spaced apart. To enable the tilting table 3 to rotate on the base 1, refer to the appendix of the instruction manual. Figure 1 and 2 As shown, a servo reduction mechanism 2 is provided on the outer side of the main spindle bearing housing 11. The power output end of the servo reducer 2 is connected to the drive shaft 13, which can drive the drive shaft 13 to rotate clockwise or counterclockwise. The servo reduction mechanism 2 consists of a servo motor and a reduction mechanism. The servo motor is connected to the reduction mechanism, and the power output shaft of the reduction mechanism is connected to the drive shaft 13, which can drive the drive shaft 13 to rotate clockwise or counterclockwise within the main spindle bearing housing 11. To limit the rotation of the tilting table 3 and prevent collision or interference between the tilting table 3 and the base 1, please refer to the appendix of the instruction manual. Figure 4 As shown, two polyurethane pads 8 are symmetrically arranged on the inner side of the main spindle bearing housing 11, below the drive shaft 13, with the drive shaft 13 as the center. The polyurethane pads 8 are mounted on the main spindle bearing housing 11 by fixing seats 81. The two polyurethane pads 8 are inclined outward at inclination angles of +45° and -45° respectively, forming an "eight" shape, which facilitates limiting the tilting angle of the tilting table 3 and improves the safety factor. In order to fix the welded plate placed on the top surface of the tilting table 3, so that the welded plate to be tested can move synchronously with the tilting table 3 and not be offset, a part of the top surface of the tilting table 3 near one of the long sides is provided for stacking. The quick-clamping device 4 for clamping and fixing the welded plates is used to position the welded plates and can be manually clamped. A movable clamping device 5 is provided near the other long side to limit the edge of the welded plate. When the size of the welded plate changes, the position of this movable clamping device 5 can be adjusted to achieve clamping. To ensure effective clamping and positioning of the welded plates, multiple sets of the quick-clamping device 4 and the movable clamping device 5 are provided, arranged at equal intervals along the length of the front and rear sides of the base 1. For details, please refer to the appendix of the instruction manual. Figure 6 As shown, the quick clamping device 4 includes a support frame 41, which is bolted to the tilting table 3. Its top is horizontal. A quick clamp 42 is located near one side of the top of the support frame 41 for clamping the lap-welded plates. A stop 43 is provided on one side of the quick clamp 42 to limit the position of one side of the lap-welded plate. To better limit the lap-welded plate, a positioning groove 431 is provided on one end of the stop 43 corresponding to the center of the tilting table 3. One side of the lap-welded plate is inserted into the positioning groove 431. (See attached instruction manual.) Figure 7 As shown, the movable clamping device 5 is fixedly mounted on the support rib 31. Specifically, the movable clamping device 5 includes a slide rail 51 and a slider 52 that slides along the slide rail 51. The slide rail 51 has a long strip structure and is fixedly mounted on the support rib 31 along its length by bolts. The slider 52 slides along the slide rail 51 and can move back and forth along the slide rail 51. A clamping block 53 for holding the welded plate is fixed to the top of the slider 52. A slot 531 is provided on the clamping block 53 at one end corresponding to the center of the flipping table 3. The other side of the welded plate corresponds to the quick clamping device 4. The plate can be inserted into the slot 531, which can also control the welded plate to prevent it from bending upwards. The welded plate is clamped and limited by the corresponding moving clamping device 5 and quick clamping device 4. In order to limit and fix the position of the slider 52 on the slide rail 51, the top of the slider 52 is provided with a threaded hole 521 that is connected vertically at the rear side of the clamping block 53. The lower end of the threaded hole 521 corresponds to the top of the slide rail 51, and a set screw that is threaded and engaged with it is provided inside. When the set screw is rotated downwards, its lower end can abut against the top of the slide rail 51 and lock it in place, thereby positioning the slider 52 on the slide rail 51.

[0032] In use, the welded lapped plate is placed on the rollers on top of the flipping table 3. First, one side is aligned and pressed against the quick clamping device 4. The side of the lapped plate corresponding to the quick clamping device 4 is inserted into the positioning groove 431 and clamped and positioned by the quick clamp 42. Then, the slider 52 on the movable top clamping device 5 is adjusted according to the width of the lapped plate so that the slot 531 on the top clamping block 53 of the slider 52 is inserted into the edge of the lapped plate. Then, the slider 52 is locked onto the slide rail 51 by the set screw, thereby realizing the flipping of the lapped plate. The servo reducer 2 drives the tumbling table 3 to rotate, which in turn drives the tumbling plate to move synchronously. The tumbling table 3 flips the tumbling plate to a suitable inspection angle (e.g., +45°) to check the welding condition on the front side of the plate. After one side is inspected, the servo reducer 2 drives the tumbling table 3 to flip the tumbling plate to another angle (e.g., -45°) to check the welding condition on the back side of the plate. This allows for observation of the welding quality on both sides of the tumbling plate, identification of defects, and repair welding on the tumbling platform.

[0033] This flipping platform for inspecting the quality of lap-welded plates facilitates the inspection of weld quality. The lap-welded plates are fixed on the flipping table 3, which can rotate the fixed lap-welded plates, allowing the front and back sides of the lap-welded plates to be flipped and presented to the inspectors. This reduces the uncontrollable dangers caused by the crane flipping, improves the safety of the flipping, and increases the inspection efficiency.

[0034] It should be emphasized that the above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
