Three-point positioning mechanism for plastic cylinder

Abstract

The invention discloses a three-point positioning mechanism for a plastic cylinder. The three-point positioning mechanism comprises a rack. Upper supporting plates are fixed to the top faces of the two sides of a top plate of the rack. At least two clamping cylinders are fixed to the outer side walls of the upper supporting plates. Push rods of the two clamping cylinders penetrate through the corresponding upper supporting plates, and connecting plates are fixed to the ends of the push rods of the clamping cylinders. Clamping blocks are fixed to opposite faces of the two connecting plates, and arc grooves are formed in the opposite walls of the two clamping blocks. A connecting groove is formed in the middle of the top face of the top plate of the rack, an expandable through hole is formed in the top face of the connecting groove, and a lifting cylinder is fixed to the bottom face of the top plate of the rack. The plastic cylinder is automatically clamped in a three-point positioned mode through the two arc grooves and the upper arc groove by adopting the clamping cylinders and the lifting cylinder, the plastic cylinder is fixedly and firmly clamped, and the effect is good; meanwhile, the clamping blocks are convenient to connect and mount and also convenient to dismount and replace.

Description

Technical field: [0001] The invention relates to the technical field of plastic processing equipment, and more specifically relates to a three-point positioning mechanism for a plastic cylinder. Background technique: [0002] When the existing cylindrical plastic products need to groove or dig holes in their side walls, they need to use equipment to clamp the cylinder body, but now there is no specific clamping device, which generally uses two screw screws Connected to the support plate, rotate the two screw rods, fix the clamping blocks at the ends of the two screw rods to clamp and fix the cylindrical body, and then manually cut it, which is very troublesome. Invention content: [0003] The purpose of the present invention is to provide a three-point positioning mechanism for a plastic cylinder in view of the deficiencies in the prior art, which uses a clamping cylinder and a lifting cylinder to automatically position three-point positioning through two arc-shaped groove...
