Positioning device in hardware tool polishing machine

Abstract

The invention relates to a positioning device in a hardware tool polishing machine. The positioning device comprises a material taking mechanical arm installed on a rack of the hardware tool positioning machine. A positioning chuck is arranged in front of the material taking mechanical arm and arranged on the rack of the polishing machine. A top positioning hole corresponding to the front end of ahardware tool is arranged in the center of the positioning chunk. The positioning chunk is provided with a pair of transverse positioning jaws symmetrical about the vertical axis of the top positioning hole. A sliding rail is arranged on one side of the positioning chunk. A sliding block is arranged on the sliding rail. The sliding block is provided with a driver. A pair of vertical positioning paws symmetrical about the transverse axis of the top positioning hole are arranged at the front end of the driver. The positioning device can accurately position a workpiece in the horizontal direction and the perpendicular direction, the central axis of a part, needing to be polished, of the workpiece is positioned, the workpiece is polished according to positioning of the central axis, so that all faces of the workpiece can be accurately polished, and the phenomenon of excessive polishing or neglect polishing can be avoided.

Description

technical field [0001] The invention relates to a positioning device in a hardware tool polishing machine. Background technique [0002] After the hardware tools are made into blanks, they need to be polished. For example, for pliers, it is necessary to polish the four sides of the pliers head. At present, ordinary small processing workshops usually use manual polishing. This polishing method not only has low work efficiency, but also the workpiece is easy to fly out during polishing, causing production accidents. At present, there are automatic polishing machines specially used for polishing workpieces. This kind of polishing machine can only be used for workpieces with neat specifications and small size deviation. However, due to the limitations of current processing conditions, it is difficult to make the blanks of hardware tools neat in specifications. When these blanks are placed in an automatic polishing machine for polishing, incomplete polishing usually occurs, suc...

Problems solved by technology

However, due to the limitation of the current processing conditions, it is difficult for the blanks of the hardware tools to be neat in specifications. When these blanks are placed in an automatic polishing machine for polishing, incomplete polishing usually occurs, such as pliers. There are differences in the bending angle and length of the pliers handle, which may easily lead to the phenomenon that one side of the pliers head is polished too deeply while the other side is not polished.
