Auxiliary manipulator system for changing mould of six-mould cold heading machine

Abstract

The invention relates to an auxiliary manipulator system for changing a mould of a six-mould cold heading machine. The auxiliary manipulator system for changing the mould of the six-mould cold heading machine is characterized by comprising a large arm, a small arm, a primary gripper, a secondary gripper, a pneumatic wrench, a pneumatic controller and other link components. The large arm is fixed to a cold heading machine through nuts; the circular tube end of a rotating connecting rod is directly arranged on an intermediate connecting post in a sleeving manner to realize rotating movement on a horizontal plane; long and short connecting rods of a large arm swing in a vertical plane; the small arm is hinged with the large arm connecting rod through thrust bearings which are arranged symmetrically, so that the small arm performs horizontal rotating movement relative to the axis of the large arm connecting rod; the auxiliary manipulator system for changing the mould of the six-mould cold heading machine is reasonable in design, compact in structure and convenient to use.

Description

technical field [0001] The invention relates to a mold changing auxiliary manipulator system for a six-mode cold pier machine. Background technique [0002] At present, with the rapid development of the national economy, the society's demand for fasteners and special-shaped parts is expanding day by day. Fasteners and special-shaped parts are the basic mechanical components of the national strategy. The cold pier process is the main way to process such parts. Since cold processing usually requires tens or hundreds of tons of force, the molds used are usually relatively heavy. The cold pier part The structure is complex and the space for mold replacement is narrow, resulting in high labor intensity for manual mold replacement, which is easy to damage other related parts of the whole machine. The difference affects the assembly accuracy, and the workers themselves are also vulnerable to injury. For example, the weight of a single mold used by DBP206 cold pier machine exceeds...

AI Technical Summary

Problems solved by technology

However, this structure requires high machining accuracy, and the cost of large-scale high-precision machining is very high, and the accuracy of the contact surface is also easily damaged. However, the installation accuracy of the mold of the cold pier machine is less than 2 wires, which is difficult to achieve
