Pneumatic positioning clamping mechanism for workpiece

Abstract

The invention discloses a pneumatic positioning clamping mechanism for a workpiece. The pneumatic positioning clamping mechanism is characterized by comprising a rack body, wherein two vertical parallel slide rods are arranged on the rack body; a first slide block and a second slide block are symmetrically arranged on the slide rods in a penetrating mode; the two sides of the rack body are equipped with swing plates; a first connecting rod and a second connecting rod are arranged on the swing plates; the side surface of the first connecting rod is fixedly connected to the side surface of the first slide block; the side surface of the second connecting rod is fixedly connected to the side surface of the second slide block; the upper end of the rack body is equipped with a first gas cylinder; a telescopic end of the first gas cylinder passes through the rack body and is fixedly connected with the first slide block; and clamping devices which are oppositely arranged are separately arranged on the first slide block and the second slide block. The pneumatic positioning clamping mechanism can simply and quickly position and clamp the workpiece, is wide in range of application, is simplein structure, and is low in cost.

Description

technical field [0001] The invention relates to the field of clamping and positioning instruments, in particular to a pneumatic positioning and clamping mechanism for workpieces. Background technique [0002] Nowadays, in the welding process of mechanical manufacturing, workpieces are prone to welding defects such as virtual welding and missing welding due to loose contact during welding. In order to solve this problem in the market, workpieces are often squeezed and reinforced, so that Welding work, so in the clamping process, it is necessary to use the welding process workpiece displacement clamping mechanism. At present, the most common workpiece structures are square and cylindrical. With the development of science and technology, different types of welding process workpiece displacement clamping mechanisms have appeared on the market, mainly through manual chucks, pneumatic chucks and hydraulic chucks for positioning.

Problems solved by technology

[0002] Nowadays, in the welding process of mechanical manufacturing, workpieces are prone to welding defects such as virtual welding and missing welding due to loose contact during welding. In order to solve this problem in the market, workpieces are often squeezed and reinforced, so that Welding work, so in the clamping process, it is necessary to use the welding process workpiece displacement clamping mechanism

At present, the most common workpiece structures are square and cylindrical. With the development of science and technology, different types of welding process workpiece displacement clamping mechanisms have appeared on the market, mainly through manual chucks, pneumatic chucks and hydraulic chucks for positioning. And to clamp round workpieces, four-jaw chucks or faceplates are used to clamp square workpieces, but these chucks are heavy and inconvenient to install, which increases the labor intensity of workers and reduces work efficiency. The cost of the disk is high, the volume is large, and it can only be applied to professional machine tools, and cannot be applied to some non-standard equipment
