The limiting mechanism includes a first fixing block for supporting one end of the sheet metal part, a clamping plate for clamping and restricting the rotation of that end of the sheet metal part, a third fixing block for supporting the other end of the sheet metal part, and a second limiting post located at the bottom for it to pass through. The robotic arm includes a driving device, a connecting frame, a connecting rod, and a connecting sleeve. The connecting frame is rotatably connected to the driving device, the connecting rod is fixed to the connecting frame, and a clamping welding component is connected below the connecting rod. The connecting sleeve flips and buckles onto the upper side of the second limiting post to jointly clamp the welded part. This patent has the following beneficial effects: it firmly fixes the plate in the fixture, improves the positioning accuracy of the welded part, reduces the labor intensity of operators, and improves the processing efficiency of the plate. However, this folding plate clamping device still has shortcomings: its limiting mechanism is a fixed structure, which can only adapt to folding plates of specific size and bending angle. When facing workpieces with different placement directions and different bending degrees, it is necessary to frequently replace the limiting parts or adjust the overall layout of the device. Its adaptability is poor and it is difficult to meet diverse processing needs. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the limiting mechanism of the above-mentioned folding plate clamping device is a fixed structure, which can only adapt to folding plates of specific size and bending angle. When facing workpieces with different placement directions and different bending degrees, it is necessary to frequently replace the limiting components or adjust the overall layout of the device, resulting in poor adaptability and difficulty in meeting diverse processing needs.

[0006] As a further improvement of this utility model, the limiting ring is configured as a ring structure with a convex cross-section, and under the locking and limiting action of the limiting groove, it is kept embedded in the side plate, so as to realize the rotatability and convenient disassembly and assembly of the limiting ring and the hydraulic cylinder and telescopic rod structure inside it relative to the side plate.

The insert plate passes through the side of the side plate and extends into the limiting circular groove, and the end is inserted into the slot outside the pressure ring to fix the pressure ring in the limiting circular groove. The limiting circular groove itself is used to fix the limiting ring in the groove.

[0009] As a further embodiment of this utility model: an adjusting plate is fixedly connected to the outer side of one end of the hydraulic cylinder near the limiting ring.

[0010] As a further improvement of this utility model: one end of the clamping plate is configured as an arc surface structure that does not obstruct rotation, and the other end is hinged to the clamping plate so that the angle between the two can be adjusted to meet the clamping and fixing requirements of folded plates with different degrees of bending.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The embodiments of this utility model will be described below based on its overall structure.

[0018] Reference Figures 1 to 7 In this embodiment of the utility model, a folding plate clamping device includes: a clamping base plate 1, two sets of side upright plates 2 are symmetrically fixed to the top surface of the clamping base plate 1, a limiting circular groove 3 is opened inside the side upright plate 2, a limiting circular ring 4 is engaged inside the limiting circular groove 3, a hydraulic cylinder 5 is fixedly inserted inside the limiting circular ring 4, a telescopic rod 6 is provided at the output end of the hydraulic cylinder 5, a clamping plate 7 is fixedly connected to the end face of the telescopic rod 6, a clamping plate 8 is hinged to the non-arc surface end of the clamping plate 7, a hinge member 17 is fixedly connected to the back side end of the clamping plate 8, a rotating screw 18 is rotatably connected inside the hinge member 17, a bidirectional screw 19 is screwed through the rotating screw 18, a holding ring 20 is fixedly sleeved in the middle section of the bidirectional screw 19, and four sets of support columns 24 are symmetrically fixed to the bottom surface of the clamping base plate 1.

[0019] Reference Figure 2 The limiting ring 4 is a ring structure with a convex cross section. Under the locking and limiting action of the limiting ring groove 3, it is kept embedded in the side plate 2 so as to realize the rotatability and convenient disassembly and assembly of the limiting ring 4 and the hydraulic cylinder 5 and telescopic rod 6 structure inside it relative to the side plate 2.

[0020] The above-mentioned scheme is adopted: the convex-shaped cross-section limiting ring 4 and the limiting groove 3 of the side plate 2 form a stepped engagement. The protruding part of the ring is precisely fitted with the inner step of the groove, which can not only prevent the limiting ring 4 from axially falling off the groove, but also reduce radial sway. This structural design allows the limiting ring 4 to rotate freely around the center of the limiting groove 3, thereby driving the internal hydraulic cylinder 5 and telescopic rod 6 to rotate synchronously, realizing multi-angle adjustment of the clamping direction. At the same time, when it is necessary to repair or replace the hydraulic cylinder 5, it is only necessary to release the fixing of the limiting ring 4, and the whole ring can be taken out from the limiting groove 3 without disassembling the side plate 2, which greatly improves the disassembly and assembly efficiency.

[0021] Reference Figures 2 to 5 One end of the limiting ring 4 is movably fitted with a pressure ring 9. The pressure ring 9 has slots 10 symmetrically opened on the outer sides of both ends. The side plate 2 has an insert plate 11 passing through the limiting groove 3 on one side. The end face of the insert plate 11 is fixedly connected with a connecting strip 12. The two ends of the connecting strip 12 are symmetrically fixedly connected with tension springs 13.

[0022] The above scheme employs a ring-shaped thin-plate structure, fitted onto the end of the limiting ring 4 near the outer side of the side plate 2. Its inner diameter is slightly larger than the outer diameter of the limiting ring 4, allowing it to rotate synchronously with the ring without affecting its rotation. The insert plate 11 is a long strip of metal plate that penetrates the side wall of the side plate 2 and extends into the limiting groove 3. Its end is fixed to the slot 10 of the pressure ring 9 in a plug-in manner. The connecting strip 12, in conjunction with the tension spring 13, keeps the insert plate 11 inserted into the slot 10, thus pressing the limiting ring 4 firmly within the limiting groove 3 via the pressure ring 9, preventing the ring from loosening due to vibration during clamping operations. When it is necessary to rotate the hydraulic cylinder 5, simply pull the connecting strip 12 to compress the spring, disengaging the insert plate 11 from the slot 10, thereby unlocking the pressure ring 9. The operation is convenient and the fixation is reliable.

[0023] Reference Figures 2 to 5 Both sides of the two sets of side plates 2 are provided with the same number of insert plates 11, connecting strips 12 and tension springs 13. The other end of the tension springs 13 is fixed to the side plate 2. The insert plates 11 penetrate the side of the side plate 2 and extend into the limiting circular groove 3. The end of the insert plate 11 is inserted into the slot 10 outside the pressure ring 9 to fix the pressure ring 9 into the limiting circular groove 3. The limiting circular groove 3 itself is used to fix the limiting ring 4 in the groove.

[0024] The above scheme employs a bidirectional fixing structure with symmetrically arranged insert plates 11 on both sides of the upright plates 2. This ensures that the clamping force of the pressure ring 9 on the limiting ring 4 is balanced, preventing the ring from tilting due to unilateral force. One end of the tension spring 13 is connected to the connecting strip 12, and the other end is fixed to the outer wall of the side upright plate 2. Its pre-tightening force ensures that the insert plate 11 is stably inserted into the slot 10, making it less likely to fall off even in high-frequency vibration environments. This triple fixing structure of the limiting groove 3, the pressure ring 9, and the insert plate 11 ensures the stability of the limiting ring 4 in the non-adjusted state while retaining the flexibility during adjustment, thus balancing operational safety and ease of operation.

[0025] Reference Figure 4 and Figure 5 An adjusting plate 14 is fixedly connected to the outer side of one end of the hydraulic cylinder 5 near the limiting ring 4. A spring insert 15 is inserted through one end of the adjusting plate 14. The spring insert 15 includes an insert body and a spring structure. One end of the spring structure is connected to the insert body and the other end is connected to the adjusting plate 14. Several sets of insert slots 16 are evenly opened around the limiting groove 3 on one side of the side plate 2. Under the action of the spring structure, the insert body of the spring insert 15 passes through the adjusting plate 14 and is inserted into the corresponding insert slot 16 to fix the rotation angle of the hydraulic cylinder 5, so as to flexibly adjust the clamping angle of the folding plate.

[0026] The above scheme is adopted: the adjusting plate 14 is a fan-shaped metal plate, which is vertically fixed to the outer wall of the hydraulic cylinder 5 and rotates synchronously with the hydraulic cylinder 5. The insert body of the spring insert 15 is cylindrical, and the tail is connected to the adjusting plate 14 through a spring. Under normal conditions, the spring is in the extended state, pushing the insert body to insert into the insert groove 16 of the side plate 2. The grooves are evenly distributed in a ring with the center of the limiting groove 3 as the center, and the distance between adjacent grooves corresponds to a fixed angle. When it is necessary to adjust the angle of the hydraulic cylinder 5, simply pull the insert body outward to compress the spring, so that it is disengaged from the insert groove 16. After rotating to the target angle, release it, and the insert will automatically lock into the corresponding groove under the action of the spring force, thus completing the angle locking. This structure realizes the stepless positioning of the rotation angle of the hydraulic cylinder 5, which can accurately adapt to the different rotation angle requirements of the folding plate and improve the adaptability of the device to different working angles.

[0027] Reference Figure 6 One end of clamping plate 7 is set as an arc surface structure that does not obstruct rotation, and the other end is hinged to clamping plate 8 so that the angle of the two can be adjusted to meet the clamping and fixing requirements of folded plates with different degrees of bending.

[0028] The above-mentioned solution employs a smooth arc transition at the curved end of clamping plate 7. When clamping plate 8 rotates around the hinge point, the curved surface will not interfere with the edge of clamping plate 8, ensuring that both can rotate flexibly between fully extended and folded. The hinge uses a high-strength hinge structure with built-in wear-resistant bearings to ensure stability even after long-term rotation. This design allows the combination angle of clamping plate 7 and clamping plate 8 to be adjusted synchronously with the bending degree of the folded plate. For example, when clamping a folded plate bent at 90 degrees, the two can form a 90-degree angle. When clamping a straight folded plate, the two can be extended to the same plane. This allows for adaptation to various workpieces without changing the clamping components, significantly improving the versatility of the device.

[0029] Reference Figure 6 The clamping plate 7 and the clamping plate 8 are provided with hinges 17 and rotating screws 18 on opposite sides. The bidirectional screws 19 are symmetrically screwed to the two sets of rotating screws 18, and the thread directions are opposite, so that the angle of the clamping plate 7 and the clamping plate 8 can be fixed at any position or fully extended.

[0030] The above scheme is adopted: the hinge 17 is a U-shaped bracket, which is fixed to the inner middle of the clamping plate 7 and the clamping plate 8 respectively. The rotating screw 18 is connected to the hinge 17 through the shaft pin and can rotate freely around the shaft pin. The two ends of the bidirectional screw 19 are machined with threads of opposite directions, which are matched with the internal threads of the two sets of rotating screws 18 respectively. When the holding ring 20 is rotated, the bidirectional screw 19 rotates, which drives the two sets of rotating screws 18 to move closer or further away synchronously along the screw axis. When they move closer, the included angle between the clamping plate 7 and the clamping plate 8 decreases. When they move further away, the included angle increases. The threaded connection has self-locking property. After the adjustment is completed, no additional fixing is required to maintain the current angle, ensuring that the folding plate will not loosen due to force during the processing. This structure can accurately control the angle and provide sufficient clamping force, taking into account both adjustment accuracy and fixation reliability.

[0031] Reference Figure 7 The clamping substrate 1 has a grid groove 21 in the center, and a material receiving box 22 is fixedly connected to the bottom surface corresponding to the grid groove 21 in the center of the clamping substrate 1. A material collection box 23 is connected to one end of the material receiving box 22 by a slide rail.

[0032] The above-mentioned scheme is adopted as follows: the grid groove 21 is a structure with densely packed elongated holes or grid holes, which is opened in the central area of ​​the clamping base plate 1, that is, directly below the folding plate. The size of its holes is sufficient to allow debris, coolant and other materials generated during processing to pass through. The receiving box 22 is a rectangular box with an open top, which is fixed to the bottom surface of the clamping base plate 1 by bolts and forms an upper and lower correspondence with the grid groove 21. It can receive debris falling from the grid groove. The collection box 23 is a pull-out structure, which is embedded in one end of the receiving box 22 by a slide rail. After the debris is collected by the receiving box 22, it finally falls into the collection box 23. This design avoids the accumulation of debris on the surface of the clamping base plate 1 and affects the positioning of the folding plate. At the same time, the pull-out collection box 23 is easy to clean regularly, reducing the amount of manual cleaning and keeping the working environment clean.

[0033] The working principle of this utility model is as follows: The device uses the clamping base plate 1 as the basic carrier, and the four sets of support columns 24 on the bottom surface provide stable support to ensure that the overall structure remains horizontal and stable during operation. The two sets of side plates 2 symmetrically arranged on the top surface provide the installation reference for the core adjustment components. The limiting groove 3 inside and the limiting ring 4 with the convex cross section form a stepped engagement, which not only restricts the ring from falling off axially, but also allows it to rotate freely, thereby driving the hydraulic cylinder 5 and telescopic rod 6 inside to rotate synchronously, laying the foundation for the clamping angle adjustment. When the rotation angle of the hydraulic cylinder 5 needs to be adjusted to match the placement direction of the folding plate, first, the connecting bar 12 is pulled to compress the tension spring 13, so that the insert plate 11 is disengaged from the slot 10 of the pressure ring 9, and the fixation of the limiting ring 4 is unlocked. Then, the hydraulic cylinder 5 is rotated, and the adjusting plate 14 fixed to its outer side rotates together. After the angle is in place, the insert body of the spring insert 15 is automatically inserted into the insert slot 16 of the side plate 2 at the corresponding angle under the action of the spring force, and the angle is locked. Finally, the connecting bar 12 is released, and the insert plate 11 is reinserted into the slot 10 under the spring tension. The pressure ring 9 presses the limiting ring 4 into the limiting groove 3 to form a triple fixation, ensuring that the hydraulic cylinder 5 does not loosen during the clamping operation. To accommodate different degrees of bending of the folded plate, the device adapts to the angle of clamping plate 7 and clamping plate 8 through an adjustable structure. The arc end of clamping plate 7 avoids interference with clamping plate 8 during rotation. The two can rotate flexibly within a 180-degree range through a hinge shaft. When the holding ring 20 in the middle section of the bidirectional screw 19 is rotated, the two sets of rotating screw cylinders 18 will move synchronously closer or further away along the axial direction because the threads at both ends of the screw are opposite. This allows for precise adjustment of the angle between the two clamping plates. The self-locking nature of the threads ensures that the angle will not loosen due to processing force after it is fixed, thus achieving a stable clamping of the folded plate. During processing, debris, coolant, and other impurities fall through the grid groove 21 in the center of the clamping substrate 1 into the material receiving box 22 fixed to the bottom surface, and finally collect in the pull-out collection box 23. This not only avoids the accumulation of impurities affecting the positioning of the folding plate, but also facilitates regular cleaning through the slide rail design, keeping the working environment clean.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
