Knife pouch push-out type chain type tool magazine

Abstract

The invention relates to a knife pouch push-out type chain type tool magazine, and aims to provide a chain type tool magazine structure which is simple in structure, small in structural space, high inmotion precision, high in tool changing speed, stable in operation, small in vibration, long in service life, low in use cost, convenient to adjust and flexible in application. The knife pouch push-out type chain type tool magazine comprises a base, an annular guide rail, a chain mechanism, a chain driving unit and a knife pouch push-out device. The base is connected with a machine tool, the annular guide rail is arranged on the base, and the chain mechanism comprising a plurality of knife pouches is arranged on the annular guide rail and can rotate along the annular guide rail under the action of the chain driving unit. The knife pouch push-out device is erected above the chain mechanism and installed on the base through a push-out installation plate, and the knife pouches can be pushedout of the chain mechanism to conduct automatic tool changing or manual tool installing.

Description

technical field [0001] The invention belongs to the field of machine tool accessories, in particular to a chain-type tool magazine with push-out tool holders. Background technique [0002] The tool magazine is an essential accessory of the CNC machining center. The high-precision, high-performance, and high-reliability tool magazine is of great significance to the CNC machine tool. The chain tool magazine is widely used in the machining center because of its large capacity. . Most of the existing chain-type tool magazines adopt the structure of sleeve roller chain and hollow roller chain. A certain number of tool sets are fixed on the chain through additional parts on the surface of the chain or hollow rollers. The chain is driven by a sprocket.

AI Technical Summary

Problems solved by technology

Most of the existing chain tool magazines adopt the structure of sleeve roller chain and hollow roller chain. A certain number of tool sets are fixed on the chain through additional parts on the surface of the chain or hollow rollers. The chain is driven by a sprocket. Due to the large number of additional parts and complex structure, this structure cannot guarantee the motion accuracy, and is limited by the chain drive motion form, and cannot obtain a high running line speed, and has defects such as large vibration, high noise, and low life.

The chain link unit in the chain structure is usually a single tool interface type, and the expandability of the tool handle is poor. To change the interface type, the entire chain structure needs to be replaced, and the cost is high

Affected by the chain pitch, manual tool loading has problems such as small operating space and inconvenient operation. At the same time, in order to avoid interference, the existing chain tool magazine needs to go through various tool preparation actions such as tool removal, flipping, and translation when changing tools. In order to change the tool with the manipulator, not only the structure is complex, but also the structural space is high, and the tool change action is cumbersome, which greatly restricts the improvement of the tool change speed of the machine tool; in addition, it is limited by the existing tool holder installation form and the tool handle locking form. Affected by the knife feeding mechanism, it is easy to cause safety hazards such as the throwing of the knife handle during the turning movement of the knife feeding mechanism

In addition, the tool feeding mechanism of the existing chain tool magazine is usually designed in a fixed position, which requires a high structural space of the machine tool, which is not conducive to the overall layout of the machine tool, and has poor versatility
