Automatic polishing mechanism for connecting holes in end parts of hardware tool connecting rod

Abstract

The invention discloses an automatic polishing mechanism for connecting holes in end parts of a hardware tool connecting rod. The automatic polishing mechanism comprises a main bottom plate, wherein an upper support frame is fixed in the middle of the top surface of the main bottom plate; a long through groove is formed in the middle of a top plate of the upper support frame; an upper pneumatic support frame is fixed on the top surface of the top plate of the upper support frame; a pressing cylinder is fixed on the top surface of a top plate of the upper pneumatic support frame; a push rod ofthe pressing cylinder penetrates the top plate of the upper pneumatic support frame, fixedly equipped with a lifting plate and inserted into the long through groove in a sleeving manner; an upper pressing block is fixed on the bottom surface of the lifting plate; an upper arc groove is formed in the bottom surface of the upper pressing block; a lower support frame is fixed on the top surface of the middle of the main bottom plate; a lower arc groove is formed in the middle of the top surface of a top plate of the lower support frame; and rod parts of a to-be-machined connecting rod are inserted into the upper arc groove and the lower arc groove in a sleeving manner. The automatic polishing mechanism can clamp the to-be-machined connecting rod automatically and polish the inner side walls of a square hole and a cylindrical hole of the connecting rod automatically, is high in efficiency and has good effect.

Description

Technical field: [0001] The invention relates to the technical field of hardware processing equipment, and more specifically relates to an automatic grinding mechanism for connecting holes at the ends of hardware tools. Background technique: [0002] In the existing hardware tools, the connecting rod is a commonly used part. It is generally formed with a rectangular block at one end of the rod, a square hole is formed at the end of the rectangular block, and a cylindrical hole is formed at the other end of the rod. The square hole and the Cylindrical holes can be connected with different connectors, but during processing, both the square holes and cylindrical holes need to be manually polished after forming, which is inefficient and labor-intensive. Invention content: [0003] The purpose of the present invention is to address the deficiencies of the prior art, and to provide an automatic grinding mechanism for the end connecting hole of a hardware tool connecting rod, whi...
