Good-stability clamping device

Abstract

The invention relates to a good-stability clamping device. The clamping device comprises clamping jaws, a jaw cavity, clamping jaw installation plates, connection rods, a push block and a cylinder. A piston rod of the cylinder and the lower end of the push block are fixed. The two connection rods are hinged to the left end and the right end of the push block through connection rod pins correspondingly. The other ends of the two connection rods are hinged to the two clamping jaws correspondingly. The jaw cavity is fixed to the upper end of the cylinder. The two clamping jaw installation plates are fixed to the upper portions of the front inner wall and the rear inner wall of the jaw cavity correspondingly and extend out of the upper end of the jaw cavity. The middle lower portions of the two clamping jaws are hinged between the two clamping jaw installation plates through clamping jaw pins correspondingly in a spaced mode. A spring piece is further fixed between the two clamping jaws through an installation pin. According to the clamping device, clamping heads are easy to replace, and usage is convenient.

Description

technical field [0001] The invention relates to a clamping device with good stability. Background technique [0002] With the popularization of industrial automation, more and more factories have introduced automated production lines. In these lines, in order to make parts or semi-finished products can be smoothly transferred between various processes, parts or semi-finished products are generally realized by clamping devices. At present, the transfer of semi-finished products usually adopts the clamping device with complex structure, inconvenient disassembly and bulky volume, and the friction force between the clamping device and parts or semi-finished products will decrease during long-term use, which will easily cause the clamped object to fall , affecting the gripping efficiency. In addition, due to the uncertain size and shape of the gripped object, it is not easy to control the opening and closing range of the gripping device. Especially after the gripped object falls,...

At present, the transfer of semi-finished products usually adopts the clamping device with complex structure, inconvenient disassembly and bulky volume, and the friction force between the clamping device and parts or semi-finished products will decrease during long-term use, which will easily cause the clamped object to fall , affecting the gripping efficiency. In addition, due to the uncertain size and shape of the gripped object, it is not easy to control the opening and closing range of the gripping device. Especially after the gripped object falls, the two jaws are easy to collide and deform. Therefore, there is an urgent need for a Grippers that meet your needs
