[0002] During the assembly or processing of workpieces, it is necessary to ensure the stability of the workpiece to improve processing accuracy and safety. Generally, a clamping device is used to clamp and fix the workpiece. Different clamping devices are generally used for different products.

[0003] For example, Chinese patent CN118056632A discloses a clamping device for providing positional support for a pipeline. The clamping device includes: a base assembly; a drive assembly, which is arranged on the base assembly; and a clamping assembly, which is movably connected to the drive assembly. The drive assembly can drive the clamping assembly to slide relative to the base assembly to adjust the distance between the clamping assembly and the base assembly.

[0004] However, when the clamping device is in use, it relies solely on the rotation of the screw to drive the pressing part to press down and clamp. The downward pressure is small and the operation is inconvenient. Moreover, because the arc groove shape of the pressing part is fixed, it is difficult to ensure its clamping stability when clamping pipes of different sizes, and it cannot be flexibly adjusted for pipes of different sizes.

[0029] In some embodiments, please refer to the accompanying drawings of the specification. Figures 1-4 , a flexible and adjustable clamping device, comprising a base 1,

[0030] The base 1 is provided with a clamping assembly 2 for clamping and fixing the product and an adjusting assembly 3 for adjusting the clamping assembly 2. The adjusting assembly 3 is connected to the clamping assembly 2 and is located below the clamping assembly 2.

[0031] The clamping assembly 2 includes a driving component 21 for providing driving thrust, a clamping component 22 for pressing down and fixing the product, and a processing placement component 23 for placing the processed product. The driving component 21, the clamping component 22 and the processing placement component 23 are installed on the base 1, the right end of the driving component 21 is connected to the clamping component 22, and the lower end of the clamping component 22 is connected to the adjustment component 3.

[0032] When the flexible and adjustable clamping device is used normally, the product is placed on the processing placement component 23, and the driving component 21 is started. The driving component 21 drives the clamping component 22 to press down and fix the product. For products of different thicknesses, the adjusting component 3 is started to adjust the clamping component 22. The setting of the adjusting component 3 makes it possible to adapt to products of different thicknesses for fixed clamping. The structural setting of the clamping component 22 driven by the driving component 21 makes the clamping mechanism stable and the downward pressure strong, which facilitates stable processing of the product.

[0033] The base 1 includes a bottom plate 11 and a bracket 12. The bracket 12 is fixedly mounted on the left side of the upper end of the bottom plate 11. The bracket 12 is an L-shaped plate. The driving component 21 is mounted on the upper end of the bracket 12. The clamping component 22 and the processing and placement component 23 are mounted on the upper end of the bottom plate 11.

[0034] The driving component 21 includes a rotating seat 211, a connecting seat 212, a cylinder 213 and a cylinder joint 214. The rotating seat 211 is fixedly installed on the left side of the upper end of the bracket 12, and the cylinder 213 is fixedly installed on the right end of the connecting seat 212. The left end of the connecting seat 212 is rotatably connected to the rotating seat 211, the output end of the cylinder 213 is fixedly connected to the cylinder joint 214, and the right end of the cylinder joint 214 is connected to the clamping component 22.

[0035] The clamping component 22 includes two first connecting frames 221, two second connecting frames 222, a pressure plate 223 and a support seat 225. The two first connecting frames 221 are respectively located at the front and rear ends of the cylinder joint 214. The upper end of the first connecting frame 221 is rotatably connected to the cylinder joint 214, and the lower end of the first connecting frame 221 is connected to the adjustment component 3. The outer sides of the upper ends of the two first connecting frames 221 are rotatably connected to the two second connecting frames 222 respectively, and the inner sides of the upper ends of the two second connecting frames 222 are rotatably connected to the left end of the pressure plate 223. The middle section of the pressure plate 223 is rotatably connected to the support seat 225 away from the second connecting frame 222, and the support seat 225 is fixedly installed on the upper end of the base plate 11.

[0036] The clamping component 22 further includes an anti-slip pad 224 . An arc-shaped groove for matching the product is opened at the right end of the pressing plate 223 , and the anti-slip pad 224 is fixedly installed at the arc-shaped groove at the right end of the pressing plate 223 .

[0037] The processing and placement component 23 includes a processing table 231 and two baffles 232. The processing table 231 is fixedly installed on the upper end of the base plate 11, and the two baffles 232 are fixedly installed on the left side of the upper end of the processing table 231. The two baffles 232 are respectively located at the front and rear ends of the pressing plate 223.

[0038] The upper end surface of the processing table 231 is lower than the lower end surface of the right side of the pressing plate 223.

[0039] The adjustment assembly 3 includes a motor 31, two fixed seats 32 and a cam 33. The two fixed seats 32 are fixedly mounted on the base plate 11, and the fixed seats 32 are located below the first connecting frame 221. The motor 31 is fixedly mounted on one side of a fixed seat 32. The central axis of the cam 33 is rotatably connected to the inner sides of the two fixed seats 32. The front and rear ends of one side of the cam 33 are rotatably connected to the lower end of the first connecting frame 221. The output end of the motor 31 is fixedly connected to the central axis of the cam 33.

[0040] When the flexible and adjustable clamping device is in normal use, the product is placed on the processing table 231 and pushed to the left to fit tightly against the baffle 232. The cylinder 213 is started, and the cylinder 213 pushes the cylinder joint 214 to the right. The cylinder joint 214 drives the first connecting frame 221 and the second connecting frame 222 to rotate. The rotation of the second connecting frame 222 drives the left end of the pressing plate 223 to rise. The pressing plate 223 rotates along the support seat 225 to move the anti-slip pad 224 downward to press the product down and fix it. When the first connecting frame 221 and the second connecting frame 222 rotate to the same straight line direction, the product is completed. To achieve self-locking, when it is necessary to adapt to products of different thicknesses, start the motor 31, and the motor 31 drives the cam 33 to rotate, so that the axial position of the lower end of the first connecting frame 221 changes, thereby changing the position of the first connecting frame 221 and the second connecting frame 222 when they reach the same straight line direction, so that the right end of the pressure plate 223 has a different height during self-locking. Through the setting of the cam 33, the axial position of the lower end of the first connecting frame 221 is changed to adapt to the self-locking position of products of different thicknesses to achieve an adjustment effect. The adjustment method is simple and convenient, and can flexibly adapt to the clamping and self-locking of products of different thicknesses.
