Description

Technical Field

[0001] This utility model belongs to the field of sheet metal welding technology, and in particular relates to a tooling for countersinking sheet metal parts. Background Technology

[0002] In modern manufacturing, sheet metal parts are widely used in various fields, from electronic device housings to automotive parts. Their processing quality is directly related to the performance and appearance of the products. Countersinking, as a key process in sheet metal processing, aims to create flat and precise countersunk holes for connecting parts such as bolts or rivets to ensure the firmness and aesthetics of the connection. Therefore, efficient sheet metal countersinking tooling is needed to perform high-quality countersinking on sheet metal parts.

[0003] However, when using existing countersinking fixtures for sheet metal parts, it is not convenient to fix the extension plate during countersinking. The T-shaped slots on the extension plate and the base plate may be misaligned under the force generated during processing, thus affecting the accuracy and stability of countersinking. Utility Model Content

[0004] The purpose of this utility model is to provide a tooling for countersinking sheet metal parts. By setting a clamping mechanism, it solves the problem that existing tooling for countersinking sheet metal parts is not convenient for fixing the extension plate during countersinking, and the T-shaped slot on the extension plate and the base plate may be misaligned under the force generated during processing, thus affecting the accuracy and stability of countersinking.

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

[0006] This utility model is a tooling for countersinking sheet metal parts, including a worktable, on which two clamping mechanisms and two buffering mechanisms are provided;

[0007] The clamping mechanism includes a rectangular slot formed on the worktable. The front and rear inner walls of the rectangular slot are fixedly connected to hinge blocks one. The two hinge blocks one are hinged to each other on the side that is close to each other, and the two hinge rods one are hinged to each other on the side that is far apart from each other. The front and rear inner walls of the rectangular slot are fixedly connected to hinge blocks two. The two hinge blocks two are hinged to each other on the side that is close to each other. The buffer mechanism includes a clamping plate set above the worktable.

[0008] Furthermore, a connecting block is hinged between the two hinge rods three. The front and rear sides of the connecting block are respectively hinged to the two hinge rods one. A hinge shaft one passes through the two hinge rods two. The hinge shaft one is rotatably connected to the two hinge rods two. A hinge block three is rotatably connected to the outer wall of the hinge shaft one.

[0009] Furthermore, a hydraulic cylinder frame is fixedly connected to the inner wall of the rectangular groove, a hydraulic cylinder is fixedly connected to the inner wall of the hydraulic cylinder frame, the output shaft of the hydraulic cylinder is fixedly connected to the hinge block three, a support frame is fixedly connected to the bottom of the worktable, a base plate is fixedly connected to the top of the worktable, an extension plate is provided on the base plate, and sheet metal parts are provided on the extension plate.

[0010] Furthermore, a plurality of hinge rods four are hinged between the connecting block and the clamping plate, and two hinge shafts two pass through the plurality of hinge rods four. The two hinge shafts two are rotatably connected to the plurality of hinge rods four respectively. The outer walls of the two hinge shafts two are slidably connected with grooved limiting blocks, and an air box is fixedly connected to the side of the two grooved limiting blocks that are close to each other.

[0011] Furthermore, two sliders are slidably connected to the inner wall of the air box, and a sliding rod is fixedly connected to the side of each slider that is far apart from each other. The side of each sliding rod that is far apart from each other extends slidably to the outside of the air box, and both sliding rods are slidably connected to the air box. The top of the upper sliding rod is fixedly connected to the connecting block, and the lower sliding rod is fixedly connected to the clamping plate.

[0012] This utility model has the following beneficial effects:

[0013] 1. By setting up a clamping mechanism, after placing the extension plate on the corresponding position on the base plate at the top of the workbench, the hydraulic cylinder of one side of the clamping mechanism is opened, and the same applies to the other side. The hydraulic cylinder pushes the hinge block three upward through the output shaft. The hinge block three drives the two hinge rods one to rotate around the hinge axis on the two hinge blocks one respectively through the hinge rod two. This causes the connecting block to rotate around the hinge axis on the hinge block one under the limit of the two hinge rods three. This causes the buffer mechanism to descend and fix the extension plate. This allows the corners of the extension plate to be clamped and fixed by pressing, thereby avoiding misalignment between the extension plate and the T-shaped slot, ensuring the accuracy and stability of the counterboring, and not interfering with the counterboring operation process.

[0014] 2. By setting a buffer mechanism, after the clamping plate contacts the extension plate, the connecting block will continue to descend, thereby driving the two sliders to approach each other in the air box through the two sliding rods. This compresses the gas between the two sliders, generating pressure that is transmitted to the clamping plate to fix the extension plate. During this process, the four hinge rods will rotate and drive the two hinge shafts to move away from each other, thereby limiting the air box through the two slotted limit blocks. This ensures the smooth progress of the clamping process, absorbs and disperses the impact force generated during processing, reduces the impact force on the extension plate and tooling, prevents misalignment of the T-shaped slots on the extension plate and the base plate, extends the service life of the tooling, and also helps to improve the processing quality of sheet metal parts.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5As shown, this utility model is a tooling for counterboring sheet metal parts, including a worktable 1. Two clamping mechanisms 2 and two buffer mechanisms 3 are provided on the worktable 1. Each clamping mechanism 2 includes a rectangular groove 211 formed on the worktable 1. Hinges 1 212 are fixedly connected to the inner walls of the front and rear sides of the rectangular groove 211. Hinges 1 213 are hinged to the sides of the two hingees 1 212 that are close to each other, and hinges 214 are hinged to the sides of the two hinges 1 213 that are far apart from each other. Hinges 215 are fixedly connected to the inner walls of the front and rear sides of the rectangular groove 211. Hinges 3 216 are hinged to the sides of the two hingees 215 that are close to each other. A connecting block 217 is hinged between the two hinges 3 216. The front and rear sides of the connecting block 217 are respectively hinged to the two hinges 1 213. Hinges 214 are passed through the two hinges 214. A hinge shaft 218 is rotatably connected to two hinge rods 214. A hinge block 219 is rotatably connected to the outer wall of the hinge shaft 218. A hydraulic cylinder frame 2110 is fixedly connected to the inner wall of the rectangular groove 211. A hydraulic cylinder 2111 is fixedly connected to the inner wall of the hydraulic cylinder frame 2110. The output shaft of the hydraulic cylinder 2111 is fixedly connected to the hinge block 219. A support frame 111 is fixedly connected to the bottom of the worktable 1. A base plate 112 is fixedly connected to the top of the worktable 1. An extension plate 113 is provided on the base plate 112. Sheet metal parts 114 are provided on the extension plate 113. By setting a clamping mechanism 2, the corners of the extension plate 113 can be clamped and fixed by pressing, thereby avoiding misalignment between the extension plate 113 and the T-shaped slot on the base plate 112, ensuring the accuracy and stability of the counterboring, and not interfering with the counterboring operation process.

[0026] The buffer mechanism 3 includes a clamping plate 311 mounted above the workbench 1. A plurality of hinge rods 312 are hinged between the connecting block 217 and the clamping plate 311. Two hinge shafts 313 pass through each of the hinge rods 312, and are rotatably connected to the hinge rods 312 respectively. Grooved limiting blocks 314 are slidably connected to the outer walls of both hinge shafts 313. An air box 315 is fixedly connected to the side of the two grooved limiting blocks 314 that is close to each other. Two sliders 316 are slidably connected to the inner wall of the air box 315. The sides of the two sliders 316 that are far apart from each other are fixedly connected to... There are two sliding rods 317, with the sides of the two sliding rods 317 extending slidably to the outside of the air box 315. Both sliding rods 317 are slidably connected to the air box 315. The top of the upper sliding rod 317 is fixedly connected to the connecting block 217, and the lower sliding rod 317 is fixedly connected to the clamping plate 311. By setting the buffer mechanism 3, the impact force generated during the processing can be absorbed and dispersed, reducing the impact force on the extension plate 113 and the tooling. This prevents the extension plate 113 from misaligning with the T-shaped slot on the base plate 112, extends the service life of the tooling, and also helps to improve the processing quality of sheet metal parts.

[0027] A specific application of this embodiment is as follows: In use, the extension plate 113 is first placed on the corresponding position on the base plate 112 at the top of the workbench 1. Then, the hydraulic cylinder 2111 of one side clamping mechanism 2 is opened to control its extension. The same applies to the other side. The hydraulic cylinder 2111 pushes the hinge block 219 upward through the output shaft. The hinge block 219 drives the two hinge rods 213 to rotate around the hinge axis on the two hinge blocks 212 respectively through the hinge rod 214. This causes the connecting block 217 to rotate around the hinge axis on the hinge block 212 under the limitation of the two hinge rods 216, thereby driving the connecting block 217 to rotate around the hinge axis on the hinge block 212. The dynamic buffer mechanism 3 descends to fix the extension plate 113. After the clamping plate 311 contacts the extension plate 113, the connecting block 217 continues to descend, thereby driving the two sliders 316 to approach each other in the air box 315 through the two sliding rods 317. This compresses the gas between the two sliders 316, thereby generating pressure that is transmitted to the clamping plate 311 to fix the extension plate 113. During this process, the four hinge rods 312 rotate and drive the two hinge shafts 313 to move away from each other, thereby limiting the air box 315 through the two slotted limit blocks 314, thus ensuring the smooth progress of the clamping process.
