Detailed Implementation

[0022] 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.

[0023] Please see Figure 1-4 In this embodiment of the utility model, a clamping device for irregular plate-shaped parts includes a mounting base 1, a mounting connecting pad 2 fixed at the bottom of the mounting base 1, a mounting connecting hole 3 opened inside the mounting connecting pad 2, and a clamping mechanism 4 fixed at the top of the mounting base 1.

[0024] The clamping mechanism 4 includes a fixed housing 41. A servo motor 42 is fixed to the inner bottom wall of the fixed housing 41. An eccentric wheel 43 is fixed to the outer side of the output shaft of the servo motor 42. A guide connecting plate 45 is fixed to one inner wall of the fixed housing 41. An anti-disengagement groove 46 is provided on one side of the guide connecting plate 45. An anti-disengagement guide block 47 is slidably connected to the guide connecting plate 45 through the anti-disengagement groove 46. A reinforced cast iron plate 48 is fixed to one side of the anti-disengagement guide block 47. A movable guide pad 44 is fixed to one end of the reinforced cast iron plate 48. A clamping component replacement mechanism 5 is fixed to one side of the movable guide pad 44. When clamping irregularly shaped plate-shaped parts, the irregularly shaped plate-shaped parts are placed on the mounting base 1. Specifically, the irregularly shaped plate-shaped parts are placed between the corresponding surfaces of two irregularly shaped plate-shaped part clamping pads 56. Then, the eccentric wheel 43 inside the clamping mechanism 4 is activated. After the eccentric wheel 43 rotates, it drives the movable guide pad 44 to move, which in turn drives the reinforced cast iron plate 48 and the anti-disengagement guide block 47 to move. One side of the anti-disengagement guide block 47 can slide in the anti-disengagement groove 46, which plays a limiting role. At the same time, the reinforced cast iron plate 48 drives the assembly threaded column 51 to move, so that the irregular plate-shaped part clamping pad 56 can stably clamp the irregular plate-shaped part. When the irregular plate-shaped part clamping pad 56 contacts the irregular plate-shaped part, the radial displacement generated by the rotation of the eccentric wheel 43 will be converted into a thrust on the irregular plate-shaped part clamping pad 56. The clamping force increases significantly with the increase of the eccentric angle. The clamping process is simple and ensures that the irregular plate-shaped part clamping pad 56 clamps the irregular plate-shaped part stably and does not loosen.

[0025] In one embodiment of this utility model, the clamping component replacement mechanism 5 includes an assembly threaded post 51, a first threaded sleeve 52 threadedly connected to the outer side of the assembly threaded post 51, a second threaded sleeve 53 threadedly connected to the outer side of the assembly threaded post 51, an assembly bracket 54 movably sleeved on the outer side of the assembly threaded post 51, a connecting bracket 55 fixed to one side of the assembly bracket 54, and a non-circular plate-shaped part clamping pad 56 fixed to one end of the connecting bracket 55. The assembly bracket 54 has a through hole inside, the size of which matches the size of the assembly threaded post 51. The assembly threaded post 51 and the movable guide pad 44 are fixedly connected. Anti-slip textures are provided on the outer sides of both the first threaded sleeve 52 and the second threaded sleeve 53. The fixed housing 41 has a through hole inside, the size of which matches the size of the assembly threaded post 51. The fixed housing 41 and the mounting base 1 are fixedly connected. The movable guide pad 44 and the... When the cast iron plate 48 is welded and fixed, and the clamping pad 56 for irregular plate-shaped parts needs to be replaced, the first threaded sleeve 52 on the outside of the assembly threaded column 51 can be rotated to remove the first threaded sleeve 52 and release the obstruction limit on the assembly bracket 54. Then, the assembly bracket 54 can be removed from the outside of the assembly threaded column 51. Then, the clamping pad 56 for the irregular plate-shaped parts that is compatible with the irregular plate-shaped parts can be taken out. The assembly bracket 54 on the outside of the clamping pad 56 is movably sleeved on the outside of the assembly threaded column 51. After the first threaded sleeve 52 and the second threaded sleeve 53 are threadedly connected to the assembly threaded column 51, the corresponding surfaces of the first threaded sleeve 52 and the second threaded sleeve 53 are made to fit tightly against the assembly bracket 54, so that the replacement of the assembly bracket 54 and the clamping pad 56 for irregular plate-shaped parts can be easily completed. The corresponding clamping module can be matched according to the shape of the part, reducing downtime and adapting to various clamping requirements for irregular plate-shaped parts.

[0026] The working principle of this utility model is as follows: This device is equipped with a clamping mechanism 4. When clamping irregularly shaped plate-like parts, the irregularly shaped plate-like parts are placed on the mounting base 1. Specifically, the irregularly shaped plate-like parts are placed between the corresponding surfaces of two irregularly shaped plate-like part clamping pads 56. Then, the eccentric wheel 43 inside the clamping mechanism 4 is activated. After the eccentric wheel 43 rotates, it drives the moving guide pad 44 to move, allowing the moving guide pad 44 to drive the reinforcing cast iron plate 48 and the anti-disengagement guide block 47 to move. One side of the anti-disengagement guide block 47 can slide in the anti-disengagement groove 46, which plays a limiting role. At the same time, the reinforcing cast iron plate 48 drives the assembly threaded column 51 to move, so that the irregularly shaped plate-like part clamping pads 56 stably clamp the irregularly shaped plate-like parts. When the irregularly shaped plate-like part clamping pads 56 contact the irregularly shaped plate-like parts, the radial displacement generated by the rotation of the eccentric wheel 43 will be converted into a thrust on the irregularly shaped plate-like part clamping pads 56. Moreover, the clamping force increases significantly with the increase of the eccentric angle. The clamping process is simple and ensures the irregularly shaped plate-like parts are clamped. The clamping pad 56 for irregularly shaped plate-shaped parts provides stable and secure clamping. This device includes a clamping component replacement mechanism 5. When the clamping pad 56 needs to be replaced, the first threaded sleeve 52 on the outside of the mounting threaded post 51 can be rotated to remove it and release the obstruction of the mounting bracket 54. The mounting bracket 54 can then be removed from the outside of the mounting threaded post 51. Next, the clamping pad 56 that matches the irregularly shaped plate-shaped part can be taken out. The mounting bracket 54 on the outside of the clamping pad 56 can be movably fitted onto the outside of the mounting threaded post 51. After the first threaded sleeve 52 and the second threaded sleeve 53 are threadedly connected to the mounting threaded post 51, the corresponding surfaces of the first threaded sleeve 52 and the second threaded sleeve 53 should be tightly against the mounting bracket 54. This facilitates the replacement of the mounting bracket 54 and the clamping pad 56. The device can match the corresponding clamping module according to the part shape, reducing downtime and adapting to various clamping requirements for irregularly shaped plate-shaped parts.

[0027] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
