Novel lifting type positioning device for movable workbench of press machine

Abstract

The invention discloses a novel lifting type positioning device for a movable workbench of a press machine. The device comprises a mounting base, a collision block body, an end cover, a lower adjusting pad, an upper adjusting pad, an air cylinder and a flange plate, the mounting base is of a vertically-through barrel structure, a first fixing screw hole and a lifting hole are formed in the upper end of the mounting base, a second fixing screw hole is formed in the lower end of the mounting base, the mounting base is fixed above a moving plane of the workbench, the collision block body is mounted in a mounting base barrel body, and the end cover is fixed in a spigot surface at the upper end of the mounting base so that the collision block body can be positioned when being lifted. The flange plate is fixed below the mounting base, the air cylinder is fixed on the flange plate, and the lower adjusting pad and the upper adjusting pad are mounted between the air cylinder and the mounting surface of the flange plate. A protruding head is arranged at the front end of a moving piston on the air cylinder, and a magnetic switch is arranged in a cylinder body. According to the moving direction of the movable workbench, the collision block body ascends or descends by controlling air inlet and air exhaust of the air cylinder, and the positioning requirement of the movable workbench during two-way starting is met.

Description

technical field [0001] The invention relates to a novel lift-type positioning device for a movable workbench of a press, which is applied in the press industry and belongs to the technical field of mechanical engineering. Background technique [0002] As an important part of the overall structure of the press, the mobile worktable is usually equipped with a worktable above it, and a T-shaped slot is opened on the top of the table to fix the lower mold or mold base, which is convenient for the user to replace the mold. As the user's requirements for production efficiency increase, the ordinary one-way mobile workbench cannot meet the user's needs for mold replacement. As a high-efficiency mold change tool, the two-way actuated mobile workbench has the advantages of low cost and less resource consumption. It can satisfy users to conveniently switch between multiple mold changing stations. However, due to the two-way movement of the mobile workbench, the ordinary fixed raised ...

Problems solved by technology

As the user's requirements for production efficiency increase, the ordinary one-way mobile workbench cannot meet the user's needs for mold replacement. As a high-efficiency mold change tool, the two-way actuated mobile workbench has the advantages of low cost and less resource consumption. It can meet the needs of users to conveniently switch between multiple mold changing stations

However, due to the two-way movement of the mobile workbench, the ordinary fixed raised workbench positioning device can only meet the positioning requirements of a single direction of the workbench because it protrudes from the moving plane of the workbench, and cannot meet the positioning requirements of the workbench’s two-way movement.
