Description

Technical Field

[0001] The utility model relates to the technical field of constant velocity joint parts, in particular to a clamping mechanism for cutting metal profiles. Background Art

[0002] In the field of metal processing, especially for the processing of complex parts such as constant velocity joint parts, the design and application of clamping mechanisms (clamping devices) are crucial. Constant velocity joint parts, as important components in the automotive transmission system, their processing accuracy and surface quality directly affect the performance and lifespan of the entire vehicle. Therefore, during the processing of constant velocity joint parts, the clamping mechanism for cutting metal profiles is particularly important.

[0003] The clamping mechanism plays an important role in fixing the workpiece, preventing movement and deformation during the cutting of metal profiles. It must be able to provide sufficient clamping force to ensure the stability of the workpiece during processing, while avoiding damage to the workpiece. For high-precision parts such as constant velocity joint parts, the design of the clamping mechanism also needs to consider how to reduce positioning errors and improve processing accuracy.

[0004] In summary, the clamping mechanism for cutting metal profiles plays a crucial role in the processing of constant velocity joint parts. With the continuous development and technological innovation of the manufacturing industry, the design and application of the clamping mechanism will also be continuously optimized and improved to meet the processing requirements of higher precision, higher efficiency and higher reliability.

[0005] The existing clamping mechanism for cutting metal profiles fixes the raw round steel used for processing constant velocity joint parts during the processing of constant velocity joint parts, facilitating the cutting of multiple round steels. During production, round steel raw materials of a certain length are usually continuously cut into round steel pieces of a fixed length. However, as the round steel is continuously cut, the length of the round steel that the clamping mechanism needs to hold is continuously decreasing. When the length of the round steel is long, in order to ensure the stability of the round steel during cutting, it is necessary to increase the clamping length of the round steel. When the round steel becomes shorter, the clamping length of the clamping mechanism is too long, making it difficult to shear the remaining round steel raw materials. Summary of the Invention

[0006] The purpose of the present invention is to provide a clamping mechanism for cutting metal profiles to solve the above-mentioned deficiencies in the prior art.

[0007] To achieve the above object, the utility model adopts the following technical solutions: A clamping mechanism for cutting metal profiles, including a base, on the top of the base are provided with a plurality of clamping blocks. The clamping block located at the middle position is fixedly installed on the top of the base, and the other clamping blocks are all slidably installed on the top of the base. On the top of the plurality of clamping blocks is fixedly provided a fixing mechanism. On one side wall of one end of the base is fixedly installed a support plate. A transmission mechanism is provided between the plurality of clamping blocks and the support plate. Through holes are opened on both the plurality of clamping blocks and the support plate.

[0008] As a further description of the above technical solution: The transmission mechanism includes two first cylinders. The two first cylinders are fixedly installed on both sides of the bottom of the support plate. The output ends of the two cylinders penetrate through the support plate and are fixedly connected to the side wall of one of the clamping blocks. A contraction component is provided between the plurality of clamping blocks.

[0009] As a further description of the above technical solution: The contraction component includes a plurality of first connecting shafts. The plurality of first connecting shafts are all fixedly installed on the side walls of the clamping blocks. On the first connecting shafts of the two clamping blocks near both ends are respectively rotatably installed two first connecting rods. The two first connecting rods are staggeredly installed on the first connecting shafts. On the other first connecting shafts are rotatably installed two second connecting rods. The two second connecting rods are staggeredly installed on the first connecting shafts. The first connecting rods and the second connecting rods in the same horizontal plane are sequentially connected end to end. At the connection of the first connecting rod and the second connecting rod and at the connection of the two second connecting rods are rotatably connected with second connecting shafts.

[0013] The utility model provides a clamping mechanism for cutting metal profiles, which has the following beneficial effects: During the processing of the constant velocity joint, it is necessary to first cut the raw round steel. When cutting the raw round steel, it is necessary to clamp the round steel. Pass the round steel through multiple through holes and disperse multiple clamping blocks. Fix the round steel through the fixing mechanism arranged at the top of the clamping blocks, so that the clamping length of the round steel by multiple clamping blocks reaches the maximum. At this time, when cutting the round steel, the round steel remains stable during the cutting process. As the round steel is continuously cut and its length is shortened, a transmission mechanism is used to drive the movement of multiple clamping blocks, so that the distance between multiple clamping blocks is shortened, and the clamping length of the round steel by multiple clamping blocks is shortened. Continue to cut the round steel. During the cutting process, the distance between the clamping blocks is continuously shortened to adapt to the continuously shortening round steel material.
