Protection device of bamboo hat type disc type tool magazine

Abstract

The invention belongs to the field of numerical control equipment, and particularly relates to a protection device of a bamboo hat type disc type tool magazine. The protection device is composed of amachine tool protection plate, flexible protection covers, a tool magazine left door, a tool magazine right door, a guide rail, a sliding chute, a connecting rod component and a driving component, wherein the machine tool protection plate isolates the tool magazine from a machine tool processing area, a tool change opening is arranged on the machine tool protection plate, the tool magazine disc can be pushed out under the action of the driving component to return to the tool change opening; the guide rail and the sliding chute are respectively arranged at an upper end and a lower end of the tool change opening, the tool magazine left door and the tool magazine right door are acted on the guide rail and the sliding chute through two sets of sliding devices and can slide along the guide railto realize the door opening and closing under the action of the driving component and the connecting rod component, the fixed ends of the two flexible protection covers are installed on the left andright sides of the tool change opening, and movable ends are respectively arranged on the tool magazine left door and the tool magazine right door. The protection device disclosed by the invention issimple in structure, short in tool change stroke, small in occupied space, free of a chip accumulation platform and easy to clean.

Description

technical field [0001] The invention belongs to the field of numerical control equipment, and in particular relates to a protective device for a hat-type disc tool magazine. Background technique [0002] The bucket hat type disc tool magazine directly completes the loosening and broaching tool change action through the coordinated movement of the machine tool spindle and the cutter head. It has the characteristics of simple structure, fast rotation speed, and convenient maintenance. In order to facilitate the tool change of the machine tool spindle, the tool magazine door of the existing bamboo hat type disc tool magazine is mostly a right-angle structure, that is, a right-angle protection platform is formed in the machine tool processing area. When the tool magazine door is opened, the machine tool spindle can directly move to the tool magazine. Tool exchange takes place inside the protective cover. On the one hand, during processing, chips will inevitably fall on the prot...

AI Technical Summary

Problems solved by technology

On the one hand, during processing, chips will inevitably fall on the protective platform of the tool magazine. As the continuous processing time increases, chips will accumulate more and more. If no additional automatic cleaning device is added, it will cause The door of the tool magazine is stuck; on the other hand, when the tool is changed, since the machine tool spindle has to move to the inside of the protective cover of the tool magazine, if the machine head is not cleaned in time, the chips attached to the machine head will be brought into the protective cover. As a result, problems such as internal pollution of the tool handle and tool magazine, and failure of the tool head rotation, etc., will also affect the machining accuracy in severe cases.

In addition, in order to avoid interference, the tool change point is far away from the zero point of the machine tool, the tool change stroke is large, and the requirements for the guide screw are high, which is not conducive to cost saving and improvement of machine tool accuracy; at the same time, it also increases the occupation of machine tool space. Not conducive to the miniaturization design of machine tools
