Protection door opening/closing device of tool machine

Abstract

The invention provides a protection door opening / closing device of a tool machine. A protection door with at least door sheet is mounted between a machining main shaft of the tool machine and a tool change device, and a driving source drives the tool change device to perform a straight reciprocating motion, so that the tool change device is displaced to a tool change position through the door sheets of the protection door to perform the tool change operation; at least one linkage set is arranged between the door sheets of the protection door and the tool change device; the linkage sets are fixed with guide plates with guide grooves on the door sheets of the protection door; the guide grooves of the guide plates have buffer sections for straightly extending and push sections for transversely extending; the tool change device is connected with connecting rods for straightly and synchronously displacing; the connecting rods are provided with guide shifting pieces slidingly arranged in the guide grooves of the guide plates; and when the tool change device is driven to perform the straight reciprocating displacement, the guide shifting pieces on the connecting rods perform reciprocating slide in the guide grooves of the guide plates to guide and drive the door plates of the protection door to pivot for opening and closing, so that the time of the tool change operation is effectively shortened, and the smooth tool change is guaranteed.

Description

technical field [0001] The invention relates to a protective door opening and closing device of a tool machine that can pivotally open and close the door panel of the protective door in conjunction with the resetting movement of the tool changing device, so as to effectively reduce the time for tool changing operations and ensure smooth tool changing. Background technique [0002] Press, the general machine tool is equipped with a tool magazine and a tool change mechanism, and the tool change mechanism performs the tool change operation between the tool magazine and the machining spindle. In addition, in order to prevent the debris and cutting fluid generated during the processing from splashing On the magazine and tool changing mechanism, a protective door that can be opened and closed is installed between the processing spindle, the tool magazine and the tool changing mechanism, and the protective door can be controlled to be closed during processing to block the splash dur...

Problems solved by technology

[0005] It utilizes the push plate 13 to directly push against the door panel 122 of the protective door 12, so that the door panel 122 of the protective door 12 is pivotally opened. Since the door panel 122 of the protective door 12 has weight and is pulled by the elastic force of the elastic element 123, therefore, When the push plate 13 pushes against the door plate 122 of the protective door 12, the door plate 122 of the protective door 12 will not only hinder the displacement action of the tool changing mechanism 112, but also make the tool changing mechanism 112 unable to move smoothly, and it is very easy to push the plate 13 and the door panel 122 of the protective door 12 produce vibration and noise colliding with each other, which in turn affects the smoothness of the tool change operation

[0006] In order to shorten the time of the tool change operation, the tool change mechanism 112 is generally driven to move quickly, but the impact force between the push plate 13 and the door panel 122 of the protective door 12 is increased, and it is easy to cause the push plate 13 and the door panel of the protective door 12 122 damage, thereby reducing the service life
