Description

Technical Field

[0001] The utility model relates to sealing component production equipment, in particular to a clamping mechanism used for processing sealing component blank rods. Background Art

[0002] Patent document CN112676643A discloses a billet sawing device that can clamp the sealing billet rods. The device includes a machine base, a discharging platform is provided on the machine base, and a longitudinal feeding platform is also provided on the machine base. A lifting mechanism is installed on the machine base at the discharge side of the discharging platform. A sawing head is slidably installed on the machine base. The sawing head and the discharging platform are respectively located on different sides of the longitudinal feeding platform. A clamping mechanism for clamping the billet rod during sawing is installed on the machine base. The sawing head corresponds to the downstream end of the longitudinal feeding platform. A longitudinal feeding mechanism for longitudinally pushing the end of the short billet rod is provided on the upstream end of the machine base near the longitudinal feeding platform. A sizing mechanism is provided on the downstream end of the machine base near the longitudinal feeding platform. The billet rod can be automatically sawed again, further reducing the waste of tail billet rods. However, the clamping mechanism is a one-way clamping structure. When the blank rod has a slight angular deviation, an angle is formed between the clamping mechanism and the blank rod, which makes the surface of the blank rod unevenly stressed, poorly stable, and produces an uneven cut surface at the sawing part, which affects the dimensional accuracy and shape accuracy. After sawing, the blank rod needs to be processed or treated additionally, which increases the production cost. Therefore, it is necessary to design a blank rod clamping mechanism to overcome the above defects. Utility Model Content
