Description

Technical Field

[0001] This invention relates to the field of sheet metal fixing technology, and in particular to a sheet metal fixing structure. Background Technology

[0002] In the process of riveting sheet metal, the sheet metal must be positioned and fixed after being transported to the position before self-piercing rivet riveting can be carried out. Traditional sheet metal fixing structures only use single-side clamping or simple bottom support, which can only achieve single-sided and single-point limiting. This makes the sheet metal prone to positional displacement during riveting, and traditional sheet metal fixing structures are difficult to adapt to sheet metals of different widths and thicknesses, resulting in poor versatility.

[0003] It is evident that existing sheet metal fixing structures suffer from unstable fixing, low positioning accuracy, and poor versatility, failing to meet the requirements of automated high-precision riveting production and processing. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a plate fixing structure that can improve the stability, positioning accuracy and versatility of fixing plates.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: The technical solution of this application proposes a plate fixing structure, which includes a fixing bracket, a second clamping mechanism and a pressing mechanism. The second clamping mechanism and the pressing mechanism are respectively disposed on the fixing bracket. The second clamping mechanism is used to clamp the two sides of the plate, and the pressing mechanism is used to press down and fix the top of the plate.

[0006] The aforementioned plate fixing structure also includes a support mechanism, which includes a roller and two bearing components. The two ends of the roller are respectively connected to the two bearing components for transmission, and the two ends of the roller are respectively connected to the fixing bracket through the bearing components. The roller is used to support the bottom of the plate.

[0007] In the aforementioned plate fixing structure, the second clamping mechanism includes a second cylinder, a third cylinder, a second linear guide, a third clamp, and a fourth clamp. The second linear guide is mounted on the fixed bracket. The second cylinder and the third cylinder are symmetrically mounted on the fixed bracket, located at opposite ends of the second linear guide. The third clamp and the fourth clamp are slidably connected to the second linear guide. The cylinder rod of the second cylinder is connected to the third clamp, and the cylinder rod of the third cylinder is connected to the fourth clamp.

[0008] In the aforementioned plate fixing structure, both the third clamp and the fourth clamp are provided with a guide mechanism on the side of the plate that is close to it. The guide mechanism is used to guide or press and fix the plate.

[0009] In the aforementioned plate fixing structure, the guiding mechanism includes a mounting base and a pulley. The mounting base is mounted on the side of the third clamp and the fourth clamp, and the pulley is rotatably mounted on the mounting base. The pulley is used to guide or press and fix the plate.

[0010] In the plate fixing structure, the second clamping mechanism further includes a first cylinder seat and a second cylinder seat. The second cylinder is mounted on the fixing frame via the first cylinder seat, and the third cylinder is mounted on the fixing frame via the second cylinder seat.

[0011] In the aforementioned plate fixing structure, the pressing mechanism includes a first connecting seat, a second connecting seat, a fourth cylinder, and a fifth cylinder. The first connecting seat is disposed on the third clamping member, the fourth cylinder is disposed on the first connecting seat, the second connecting seat is disposed on the fourth clamping member, and the fifth cylinder is disposed on the second connecting seat. Pressing members are disposed on the cylinder rods of the fourth cylinder and the fifth cylinder.

[0012] The plate fixing structure further includes a synchronous transmission mechanism, which is connected to the second clamping mechanism. The synchronous transmission mechanism is used to balance and coordinate the process of the second clamping mechanism clamping the plate.

[0013] In the aforementioned plate fixing structure, the synchronous transmission mechanism includes an annular conveyor belt, two pulley groups, a first fixing member, and a second fixing member. The annular conveyor belt is connected to the two pulley groups for transmission. The two pulley groups are respectively mounted on the first cylinder seat and the second cylinder seat. The third clamp and the fourth clamp are located within the ring of the annular conveyor belt. One side of the third clamp is connected to one side of the annular conveyor belt through the first fixing member, and one side of the fourth clamp is connected to the other side of the annular conveyor belt through the second fixing member. The connection between the third clamp and the annular conveyor belt is offset from the connection between the fourth clamp and the annular conveyor belt.

[0014] In the plate fixing structure, the pulley assembly includes a pulley seat and a gear. The gear is rotatably mounted on the pulley seat. The annular conveyor belt is connected to the gear on the first cylinder seat and the gear on the second cylinder seat.

[0015] Beneficial effects: 1. Strong stability and high positioning accuracy of the plate: The plate is fixed by clamping on both sides of the second clamping mechanism and pressing down on the top of the pressing mechanism, which effectively avoids positional displacement during the riveting operation and greatly improves the positioning accuracy and stability of the plate.

[0016] 2. Wide versatility: The second clamping mechanism can flexibly adjust the clamping distance, and when combined with the top pressing mechanism, it can be used to fix plates of different widths and thicknesses, making it more widely applicable.

[0017] 3. Good clamping synchronization: The addition of a synchronous transmission mechanism ensures that the third and fourth clamps move synchronously in opposite directions, resulting in uniform clamping force and preventing misalignment caused by unilateral pushing of the plate, thus further ensuring positioning accuracy.

[0018] 4. Smooth conveying and guiding: The third and fourth clamps are equipped with guiding mechanisms, which can guide the sheet metal during conveying and assist in clamping during fixing, thus balancing smooth conveying and reliable clamping. Attached Figure Description

[0024] Please see Figure 1 and Figure 2 The present invention provides a plate fixing structure, which includes a fixing bracket 1, a second clamping mechanism 3 and a pressing mechanism 4. The second clamping mechanism 3 and the pressing mechanism 4 are respectively disposed on the fixing bracket 1. The second clamping mechanism 3 is used to clamp the two sides of the plate, and the pressing mechanism 4 is used to press down and fix the top of the plate.

[0025] In actual operation, the second clamping mechanism 3 clamps on both sides and the pressing mechanism 4 presses down from the top to constrain the plate in all directions, effectively preventing positional displacement during the riveting process and greatly improving the positioning accuracy and stability of the plate. At the same time, the second clamping mechanism 3 can flexibly adjust the clamping distance, and together with the top pressing mechanism 4, it can be adapted to fix plates of different widths and thicknesses, making it more widely applicable.

[0026] like Figure 1 As shown, in some embodiments, a support mechanism 2 is further included. The support mechanism 2 is used to support the bottom of the board. The support mechanism 2 includes a roller 21 and two bearing components 22. The two ends of the roller 21 are respectively connected to the two bearing components 22 for transmission. The two ends of the roller 21 are respectively connected to the fixed bracket 1 through the bearing components 22. The roller 21 is used to support the bottom of the board. The bottom of the board can be directly placed on the roller 21. The roller 21 can rotate freely, which can stably support the weight of the board and reduce the frictional resistance during the transfer of the board. The entire roller 21 can be a one-piece long shaft to achieve stable support for the bottom of the board.

[0027] It should be noted that in actual operation, the bottom of the board can also be supported by the rollers on the conveying equipment. The specific configuration can be determined according to the actual needs of the board production line. Therefore, there is no limitation on the support structure at the bottom of the board.

[0028] like Figure 1 As shown, in some embodiments, the second clamping mechanism 3 includes a second cylinder 31, a third cylinder 32, a second linear guide 33, a third clamp 34, and a fourth clamp 35. The second linear guide 33 is mounted on a fixed bracket 1. The second cylinder 31 and the third cylinder 32 are symmetrically mounted on the fixed bracket 1, and are located at both ends of the second linear guide 33. The third clamp 34 and the fourth clamp 35 are slidably connected to the second linear guide 33. The cylinder rod of the second cylinder 31 is connected to the third clamp 34, and the cylinder rod of the third cylinder 32 is connected to the fourth clamp 35. In actual operation, the second cylinder 31 and the third cylinder 32 extend synchronously, driving the third clamp 34 and the fourth clamp 35 to move towards each other along the second rail 33, clamping the plate from both sides; conversely, the second cylinder 31 and the third cylinder 32 retract synchronously, driving the third clamp 34 and the fourth clamp 35 to move away from each other along the second rail 33, releasing the plate; the adjustable stroke of the dual cylinders can be used to fix plates of different widths.

[0029] Combination Figure 1 and Figure 2 Therefore, preferably, in some embodiments, both the third clamp 34 and the fourth clamp 35 are provided with a guide mechanism 5 on the side of the plate closest to it. The guide mechanism 5 is used to guide or press and fix the plate. The guide mechanism 5 avoids the third clamp 34 and the fourth clamp 35 from rigidly contacting the plate and scratching the appearance surface, thus taking into account the functions of guiding, clamping and protecting.

[0030] like Figure 2 As shown, in a further preferred embodiment, the guide mechanism 5 includes a mounting base 51 and a pulley 52. ​​The mounting base 51 is mounted on the side of the third clamp 34 and the fourth clamp 35. The pulley 52 is rotatably mounted on the mounting base 51 and is used to guide or press and fix the sheet material. During the sheet material feeding stage, the pulley 52 on the third clamp 34 and the fourth clamp 35 forms a guide channel to limit the left and right movement of the sheet material, ensuring that the sheet material accurately enters the clamping position. At the same time, the pulley 52 fits against the side wall of the sheet material to achieve flexible pressing and avoid scratching the surface of the sheet material.

[0031] Furthermore, pulley 52 can be made of rubber, which has advantages such as shock absorption and good elasticity; of course, pulley 52 can also be made of other materials, which are not limited here.

[0032] Combination Figure 1and Figure 2 As can be seen, in some embodiments, the second clamping mechanism 3 further includes a first cylinder seat 36 and a second cylinder seat 37. The second cylinder 31 is mounted on the fixed frame via the first cylinder seat 36, and the third cylinder 32 is mounted on the fixed frame via the second cylinder seat 37. The first cylinder seat 36 and the second cylinder seat 37 enable the feasibility of mounting the second cylinder 31 and the third cylinder 32 on the fixed frame.

[0033] See Figure 1 Specifically, in some embodiments, the pressing mechanism 4 includes a first connecting seat 41, a second connecting seat 42, a fourth cylinder 43, and a fifth cylinder 44. The first connecting seat 41 is mounted on the third clamping member 34, the fourth cylinder 43 is mounted on the first connecting seat 41, the second connecting seat 42 is mounted on the fourth clamping member 35, and the fifth cylinder 44 is mounted on the second connecting seat 42. Pressing members 45 are mounted on the cylinder rods of both the fourth cylinder 43 and the fifth cylinder 44. The pressing members 45 on both cylinders are driven by the fourth cylinder 43 and the fifth cylinder 44 to move up and down, thereby achieving the pressing and fixing of the sheet metal.

[0034] Combination Figure 1 , Figure 2 and Figure 3 It can be seen that, preferably, in some embodiments, a synchronous transmission mechanism 6 is also included. The synchronous transmission mechanism 6 is connected to the second clamping mechanism 3 for transmission. The synchronous transmission mechanism 6 is used to balance and link the second clamping mechanism 3 in the process of clamping the plate, thereby further improving the accuracy of the second clamping mechanism 3 in clamping the plate.

[0035] like Figure 1 and Figure 2 As shown, further, in some embodiments, the synchronous transmission mechanism 6 includes an annular conveyor belt 61, two pulley sets 62, a first fixing member 63 and a second fixing member 64. The annular conveyor belt is connected to the two pulley sets 62. The two pulley sets 62 are respectively disposed on the first cylinder seat 36 and the second cylinder seat 37. The third clamp 34 and the fourth clamp 35 are located inside the ring of the annular conveyor belt 61. One side of the third clamp 34 is connected to one side of the annular conveyor belt 61 through the first fixing member 63. One side of the fourth clamp 35 is connected to the other side of the annular conveyor belt 61 through the second fixing member 64. The connection between the third clamp 34 and the annular conveyor belt 61 and the connection between the fourth clamp 35 and the annular conveyor belt 61 are relatively staggered. When the second cylinder 31 and the third cylinder 32 drive each other simultaneously, the third clamp 34 and the fourth clamp 35 move towards each other along the length of the second linear guide 33. Through the transmission connection between the annular conveyor belt 61 and the two pulley sets 62, the third clamp 34 and the fourth clamp 35 are further balanced and linked, making the movement of the third clamp 34 and the fourth clamp 35 more stable and greatly improving the stability of the third clamp 34 and the fourth clamp 35 in clamping and fixing the plate.

[0036] like Figure 2 As shown, in some embodiments, the pulley assembly 62 includes a pulley seat 621 and a gear 622. The gear 622 is rotatably mounted on the pulley seat 621. In actual installation, the first cylinder seat 36 and the second cylinder seat 37 are respectively equipped with pulley seats 621. After installing the gear 622 on each pulley seat 621, the annular conveyor belt 61 is connected to the gear 622 on the first cylinder seat 36 and the gear 622 on the second cylinder seat 37.

[0037] In summary, the bottom of the plate can be attached to the roller 21 of the support mechanism 2. The roller 21 can rotate freely through the bearing 22 to reduce the friction of the plate during transport. At the same time, the pulleys 52 on the third clamp 34 and the fourth clamp 35 form a guide channel to limit the plate to the left and right, ensuring that the plate accurately enters the clamping center position. When the plate reaches the preset positioning point, the second cylinder 31 and the third cylinder 32 extend synchronously towards each other, driving the third clamp 34 and the fourth clamp 35 to move towards each other along the length direction of the second linear guide 33. During this process, the synchronous transmission mechanism 6 is driven by the gears 622 of the pulley group 62 on both sides through the ring conveyor belt 61, and the staggered connection between the third clamp 34, the fourth clamp 35 and the ring conveyor belt 61, so as to realize the balanced linkage of the third clamp 34 and the fourth clamp 35, ensuring that the clamping action is synchronous and the force is uniform. The pulley 52 moves with the third clamp 34 and the fourth clamp 35 and flexibly fits against the side wall of the plate, completing the clamping and fixing of both sides of the plate. Subsequently, the fourth cylinder 43 and the fifth cylinder 44 extend synchronously, driving the pressing part 45 to move downward, pressing down and limiting the top of the plate. Combined with the support of the roller 21 at the bottom of the plate, the plate is fixed. The overall adjustable characteristics are suitable for plates of different widths and thicknesses. The synchronous transmission mechanism 6 and the guide mechanism 5 further improve the positioning accuracy and clamping stability, effectively meeting the needs of automated high-precision riveting production and processing.
