[0031] The present invention will be further described below with reference to the accompanying drawings.

[0032] Example 1

[0033] This embodiment provides a positioning fixture for bending workpieces, such as... Figure 1 As shown, the system includes a worktable 1, a positioning component 2, a transfer component 3, and a laser marking machine 4. The positioning component 2 is disposed on the surface of the worktable 1 and is used to place bent workpieces. The transfer component 3 is disposed on the surface of the worktable 1. The laser marking machine 4 is disposed on the transfer component 3 and is used to move back and forth along one end of the worktable 1 surface to the other end of the worktable 1 surface under the action of the transfer component 3. The laser marking machine 4 is located above the positioning component 2 and is used to mark and print on the bent workpieces.

[0034] For example, during implementation, the positioning component 2 is installed on the table surface of the workbench 1 by means of screw fixing, welding fixing, etc. The positioning component 2 is used to place the bent workpiece to be marked.

[0035] The transfer assembly 3 is installed on the workbench 1 by means of welding, screwing, or other methods.

[0036] The laser marking machine 4 can use existing lasers such as fiber lasers, CO2 lasers, and ultraviolet lasers. The laser marking machine 4 is installed on the transfer assembly 3 by means of screw fixing or snap-fit, and the laser marking machine 4 is located above the positioning assembly 2.

[0037] During operation, the operator places the bent workpiece to be marked on the positioning component 2. The transfer component 3 then moves the laser marking machine 4 from one end of the worktable 1 to the other, allowing it to mark the bent workpiece below it. After marking the workpiece, the transfer component 3 moves the laser marking machine 4 from one end of the worktable 1 to the other, facilitating the next marking operation. The positioning component 2 positions the bent workpiece to reduce operator error and increase the probability of correctly aligning each workpiece with the marking area of ​​the laser marking machine 4, thus reducing the risk of inaccurate or failed marking.

[0038] Example 2

[0039] Based on the above embodiment 1, in this embodiment, as follows: Figure 1 As shown, the transfer assembly 3 includes a drive component 31, a first slider 32, and a guide block 33; the guide block 33 is disposed on the table surface of the worktable 1; a first guide groove 5 is formed on the guide block 33, and the first guide groove 5 extends from one end of the table surface of the worktable 1 to the other end of the table surface of the worktable 1; the first slider 32 is disposed in the first guide groove 5, and the first slider 32 is connected to the laser marking machine 4; the drive component 31 is disposed on the guide block 33, and the drive component 31 is connected to the first slider 32; wherein, the drive component 31 is used to cause the first slider 32 to move back and forth along one end of the first guide groove 5 to the other end of the first guide groove 5.

[0040] For example, during implementation, the guide block 33 is connected to the table surface of the workbench 1 by welding, screwing, or other means. A first guide groove 5 is provided on the upper surface of the guide block 33, which extends from one end of the table surface of the workbench 1 to the other end of the table surface of the workbench 1.

[0041] The first slider 32 is slidably disposed within the first guide groove 5, allowing it to reciprocate along one end of the first guide groove 5 to the other end under external force. Furthermore, the first slider 32 is connected to the laser marking machine 4 via screw fixing, snap-fit, or other means to ensure that when the first slider 32 reciprocates along one end of the first guide groove 5 to the other end, it can synchronously drive the laser marking machine 4 to reciprocate along one end of the worktable 1 surface to the other end.

[0042] The drive component 31 is connected to the guide block 33 by means of screw fixing, snap-fit, etc., and the output shaft of the drive component 31 is connected to the first slider 32 by means of welding fixing, screw fixing, etc., so as to ensure that when the drive component 31 is running, the drive component 31 can drive the first slider 32 to move back and forth in the first guide groove 5 from one end of the first guide groove 5 to the other end of the first guide groove 5.

[0043] During operation, when the drive unit 31 rotates in the forward direction, it drives the first slider 32 to move within the first guide groove 5 from one end to the other, thereby driving the laser marking machine 4 to move synchronously from one end of the worktable 1 to the other. When the drive unit 31 rotates in the reverse direction, it drives the first slider 32 to move within the first guide groove 5 from one end to the other, thereby driving the laser marking machine 4 to move synchronously from one end of the worktable 1 to the other. The cooperation between the first guide groove 5 and the first slider 32 makes the movement of the laser marking machine 4 smoother, aiming to reduce the risk of deviation or wobbling, and thus lower the risk of inaccurate or failed marking.

[0044] Example 3

[0045] Based on the above embodiment 2, in this embodiment, as follows: Figure 2 or Figure 6 As shown, the driving component 31 includes a driving motor 311 and a driving rod 312; the driving motor 311 is disposed at one end of the first guide groove 5; the driving rod 312 is disposed in the first guide groove 5, the driving rod 312 is connected to the output shaft of the driving motor 311, and the end of the driving rod 312 away from the driving motor 311 is rotatably connected to the other end of the first guide groove 5; the first slider 32 is screwed to the driving rod 312, and the first slider 32 is in contact with the groove wall of the first guide groove 5.

[0046] For example, in the implementation process, the aforementioned driving component 31 includes a driving motor 311 and a driving rod 312. The driving motor 311 can be a stepper motor, servo motor, or the like. The driving motor 311 is disposed within the first guide groove 5, located at one end of the first guide groove 5, and is connected to the bottom of the first guide groove 5 by means of screw fixing, snap-fit, or other methods.

[0047] The drive rod 312 is disposed in the first guide groove 5. The drive rod 312 is disposed parallel to the bottom of the first guide groove 5. One end of the drive rod 312 is connected to the output shaft of the drive motor 311 by means of screw fixing, welding fixing or coupling connection, etc., and the other end of the drive rod 312 is rotatably connected to the other end of the first guide groove 5 by means of bearing connection, shaft hole connection or other rotating device connection.

[0048] The first slider 32 is threadedly connected to the drive rod 312, and the first slider 32 is attached to the groove wall of the first guide groove 5.

[0049] During operation, when the drive motor 311 rotates in the forward direction, the drive rod 312 rotates clockwise, causing the first slider 32 to move along the drive rod 312 within the first guide groove 5, from one end of the first guide groove 5 to the other end, under the limiting action of the groove wall. This, in turn, drives the laser marking machine 4 to move synchronously from one end of the worktable 1 to the other end. When the drive motor 311 rotates in the reverse direction, the drive rod 312 rotates counterclockwise, causing the first slider 32 to move along the drive rod 312 within the first guide groove 5, from one end of the first guide groove 5 to the other end, under the limiting action of the groove wall. This, in turn, drives the laser marking machine 4 to move synchronously from one end of the worktable 1 to the other end. By utilizing the screw transmission mechanism of the drive motor 311 and the drive rod 312, it is hoped that compared with direct linear drive, a smoother motion characteristic can be provided, thereby reducing impact and vibration, making the laser marking machine 4 more stable during movement, and reducing the risk of inaccurate marking or failure.

[0050] Example 4

[0051] Based on the above embodiment 2, in this embodiment, as follows: Figure 1 As shown, the transfer assembly 3 further includes a vertical beam 34, a horizontal beam 35, and an adjusting member 36; the vertical beam 34 is disposed on the table surface of the worktable 1; the horizontal beam 35 is disposed on the vertical beam 34 and is connected to the guide block 33; the adjusting member 36 is disposed on the vertical beam 34 and is connected to the horizontal beam 35; wherein, the adjusting member 36 is used to adjust the distance between the horizontal beam 35 and the table surface of the worktable 1.

[0052] For example, in the implementation process, the above-mentioned transfer component 3 also includes a vertical beam 34, a horizontal beam 35 and an adjusting member 36.

[0053] The vertical beam 34 is connected to the workbench 1 by welding, screwing or other means.

[0054] The adjusting component 36 can adopt a manual screw, hydraulic cylinder, electric push rod or other structure, and the adjusting component 36 is connected to the vertical beam 34 by welding, screwing or other methods.

[0055] During operation, when marking bent workpieces, the operator can adjust the height of the crossbeam 35 using the adjusting component 36 before marking, based on the specific characteristics of the workpiece (such as thickness and shape). This changes the working height of the laser marking machine 4. The aim is to make the positioning fixture adaptable to bent workpieces of different sizes and shapes, thereby enhancing its adaptability. After adjusting the height, the adjusting component 36 is locked to reduce the risk of the crossbeam 35 sliding during marking.

[0056] Example 5

[0057] Based on the above embodiment 4, in this embodiment, as follows: Figure 5 As shown, the adjusting component 36 includes a second slider 361, a limiting plate 362, a connecting plate 363, and a connecting rod 364; the connecting plate 363 is connected to the crossbeam 35; one end of the connecting plate 363 away from the crossbeam 35 is connected to the vertical beam 34; a second guide groove 6 is provided on the vertical beam 34; the second guide groove 6 extends from the lower end of the vertical beam 34 to the upper end of the vertical beam 34; the limiting plate 362 is disposed in the opening of the second guide groove 6; the second slider 361 is slidably disposed in the second guide groove 6; the connecting rod 364 passes through the connecting plate 363 and the second slider 361; wherein, the connecting rod 364 is used for the connecting plate 363 and the second slider 361 to abut against both sides of the limiting plate 362 respectively.

[0058] For example, during implementation, such as Figure 4 or Figure 8 As shown, a second guide groove 6 is provided on the side of the vertical beam 34 near the horizontal beam 35. The second guide groove 6 extends from the lower end of the vertical beam 34 to the upper end of the vertical beam 34.

[0059] like Figure 5 or Figure 9 As shown, the aforementioned adjusting component 36 includes a second slider 361, a limiting plate 362, a connecting plate 363, and a connecting rod 364.

[0060] The second slider 361 is slidably disposed in the second guide groove 6, the second slider 361 is attached to the groove wall of the second guide groove 6, and the second slider 361 is provided with a threaded hole.

[0061] The limiting plate 362 is connected to the opening of the second guide groove 6 by means of welding, screwing, or integral molding, so as to reduce the risk of the second slider 361 sliding out of the opening of the second guide groove 6.

[0062] One end of the connecting plate 363 is connected to the crossbeam 35 by welding, screwing or other means, and the other end of the connecting plate 363 has a connecting hole.

[0063] One end of the connecting rod 364 passes through the connecting hole on the connecting plate 363 and the slot of the second guide groove 6 in sequence, and the other end of the connecting rod 364 is screwed into the threaded hole on the second slider 361.

[0064] During use, when it is necessary to adjust the working height of the laser marking machine 4, the operator rotates the connecting rod 364 counterclockwise. At this time, as... Figure 3 or Figure 5 As shown, under the limiting action of the second guide groove 6 wall, the screw depth between the second slider 361 and the connecting rod 364 is reduced, resulting in a gap between the second slider 361 and the limiting plate 362. In this state, both the second slider 361 and the connecting rod 364 maintain a sliding connection with the second guide groove 6. At this time, the operator can push the crossbeam 35 to move up and down relative to the worktable 1, so that the connecting plate 363 moves up and down relative to the worktable 1. At the same time, the second slider 361 and the connecting rod 364 slide up and down along the second guide groove 6.

[0065] When the working height of the laser marking machine 4 is adjusted, the operator rotates the connecting rod 364 clockwise. At this time, as... Figure 7 and Figure 9 As shown, under the limiting action of the second guide groove 6 wall, the screw depth between the second slider 361 and the connecting rod 364 increases, thereby causing the second slider 361 and the connecting plate 363 to abut against both sides of the limiting plate 362. In this state, both the second slider 361 and the connecting rod 364 remain relatively fixed to the second guide groove 6. Through the sliding connection between the second slider 361 and the second guide groove 6, and the stable connection between the connecting rod 364 and the connecting plate 363 and the second slider 361, the purpose of adjusting and fixing the working height of the laser marking machine 4 is to be achieved.

[0066] Example 6

[0067] Based on the above embodiment 1, in this embodiment, as follows: Figure 1 As shown, the positioning component 2 includes a first support rod 21; the first support rod 21 is disposed on one side of the worktable 1 surface and is located below the laser marking machine 4; wherein, the first support rod 21 is used to fit against the lower surface of the middle part of the bent workpiece.

[0068] For example, in the implementation process, the positioning component 2 includes a first support rod 21. The first support rod 21 is connected to one side of the worktable 1 surface by means of welding, screwing, or other methods. The first support rod 21 is located below the laser marking machine 4 and is used to fit against the lower surface of the middle part of the bent workpiece.

[0069] During use, when marking bent workpieces, the bent workpiece is placed on the first support rod 21, with the lower surface of the middle part of the bent workpiece adhering to the first support rod 21. This aims to reduce the distance error between the upper surface of each bent workpiece and the laser marking machine 4, thereby reducing the risk of inaccurate or failed marking of the bent workpiece.

[0070] Example 7

[0071] Based on the above embodiment 6, in this embodiment, as follows: Figure 1 As shown, the positioning component 2 also includes a baffle 22; the baffle 22 is disposed on one side of the worktable 1 surface, the baffle 22 is located below the laser marking machine 4, and a limiting groove is formed between the baffle 22 and the first support rod 21; wherein, the limiting groove is used to accommodate the bent workpiece.

[0072] For example, in the implementation process, the positioning component 2 also includes a baffle 22. The baffle 22 is connected to one side of the worktable 1 surface by welding, screwing, or other means, and the baffle 22 is located below the laser marking machine 4. One end of the baffle 22 away from the worktable 1 surface forms a limiting groove with the upper surface of the first support rod 21, and the limiting groove is used to accommodate the bent workpiece.

[0073] During operation, when marking bent workpieces, the operator places the bent workpiece into the limiting groove, ensuring the lower surface of the workpiece is against the groove wall (the upper surface of the first support rod 21), and the side surface of the workpiece is against the bottom of the receiving groove (the end of the baffle 22 away from the worktable 1). This aims to reduce the distance error between the upper surface of each bent workpiece and the laser marking machine 4, as well as the distance error between each bent workpiece and the laser marking machine 4 from one side of the worktable 1 to the other side, thereby reducing the risk of inaccurate or failed marking of the bent workpiece.

[0074] Example 8

[0075] Based on the above embodiment 7, in this embodiment, as follows: Figure 1 As shown, the baffle 22 is connected to one end of the first support rod 21 near the worktable 1.

[0076] For example, during implementation, the baffle 22 is located at one end of the first support rod 21 near the other side of the worktable 1. This causes the opening of the limiting groove to be located at the other end of the limiting groove away from the worktable 1, in order to facilitate the operator to place the bent workpiece into the receiving groove from the opening of the receiving groove.

[0077] Example 9

[0078] Based on the above embodiment 8, in this embodiment, as follows: Figure 4 or Figure 8 As shown, the upper surface of the first support rod 21 has an upwardly curved arc structure.

[0079] For example, during implementation, the upper surface of the first support rod 21 has an upwardly curved arc structure. This is intended to ensure that the lower surface of the bent workpiece adheres to the groove wall of the limiting groove (the upper surface of the first support rod 21), reducing the contact area between the bent workpiece and the groove wall, thereby reducing the risk of wear when the bent workpiece slides from the opening of the limiting groove to the bottom of the limiting groove or from the bottom of the limiting groove to the opening of the limiting groove.

[0080] Example 10

[0081] Based on the above embodiment 7, in this embodiment, as follows: Figure 1 As shown, the positioning component 2 further includes a second support rod 23; the second support rod 23 is connected to one side of the worktable 1 surface; there are two second support rods 23; the two second support rods 23 are distributed on both sides of the first support rod 21; the second support rod 23 is used to fit against the lower end face of the bent workpiece end.

[0082] For example, in the implementation process, the positioning component 2 further includes a second support rod 23. The second support rod 23 is connected to one side of the workbench 1 surface by means of welding, screwing, or other methods. There are two second support rods 23, which are distributed on both sides of the first support rod 21.

[0083] During use, when marking bent workpieces, the operator places the bent workpiece into the limiting groove, ensuring that the lower end face of the middle of the bent workpiece is against the upper surface of the first support rod 21, while the lower end faces of both ends of the bent workpiece are against the upper surfaces of the two second support rods 23 respectively. This aims to provide additional support points for the bent workpiece at both ends using the second support rods 23, thereby enhancing the stability of the bent workpiece throughout the marking process and reducing the risk of inaccurate or failed marking.

[0084] Alternatively, the bent workpiece can be suspended between two second support rods 23, with the lower ends of both ends of the bent workpiece respectively attached to the upper surfaces of the two second support rods 23, thus temporarily storing the bent workpiece. This aims to facilitate the temporary storage of bent workpieces by operators.
