Description

Tool magazine
The invention relates to a related field of a vertical processing machine, in particular to a tool magazine mechanism of a processing machine capable of improving tool change efficiency.
According to the chain cutter magazine of the general processing machine, the main body of the tool magazine is provided with a plurality of driven sprocket wheels and a driving sprocket, and a chain with a knife holder is arranged around the driven sprocket and the driving sprocket. A variety of different processing tools are mounted on the chain; the driving sprocket drives the chain to rotate, so that the machining tool on the tool holder is displaced to the tooling position of the tool magazine body, and then the machining tool is moved out of the tool body to perform the conversion. Knife work.
However, vibration occurs during the operation of the chain. If the processing machine is still in the process of processing, the machining accuracy is often inaccurate; and the vibration generated by the chain movement easily affects the movement of the machining tool to the machining. The accuracy of the location.
In addition, the chain is composed of a plurality of links, and the distance between the links is fixed. When the machining tool is set on the chain, it is limited by the distance between the links, and cannot be arranged at equal intervals. Further, the machining tool is divided into large diameters. Knives and small-diameter knives, because of the large size of the large-diameter knives, in order to match the distance between the links, the sides of the large-diameter knives must be vacant, so that they can be fixed on the chain, but the machining tools will be reduced. The number of installations is a waste of installation space.
In addition, the weight of the large-diameter knife is heavier than that of the small-diameter knife. In order to avoid mistakes in the movement of the large-diameter knife, the speed of the large-diameter knife moving to the cutting position cannot be too fast, and the general processing machine is not processed differently. The tool size changes the movement and the tool change speed. Therefore, in order to match the speed of the large-diameter knife, the movement and the tool change speed can be reduced in an all-round manner, resulting in a decrease in machining efficiency. Moreover, when the chain is actuated, in order to drive all the processing tools to move, it is necessary to drive the chain to move with a large power source, thereby relatively increasing the power consumed, thereby causing waste of energy.
In order to solve the above problems, the present invention provides a tool magazine mechanism of a processing machine, wherein a control unit controls a knife removing device to extract a required tool, thereby replacing a conventional chain drive through a knife removing device to avoid vibration when moving. The problem of inaccurate accuracy can also be achieved by quickly and efficiently selecting a tool for tool change.
An embodiment of the present invention provides a tool magazine mechanism of a processing machine, comprising: a tool magazine body; a fixing member disposed on the tool body, the fixing member is provided with a plurality of tools at intervals; and a knife removing device is arranged along the The moving track is slidably disposed on the tool body; and a control unit is electrically connected to the knife removing device, and the control unit is configured to control the tool removing device to extract one of the tools corresponding to the specific position.
According to the above, the utility model can achieve the effect that the control unit controls the knife removing device to extract the required tool, thereby replacing the conventional chain drive with the knife removing device, and there is no vibration during the operation of the knife removing device. The generation can avoid the problem of inaccuracies in accuracy caused by vibration, and thus can achieve fast and efficient tool selection and tool change operations.
Furthermore, by replacing the conventional chain drive with the knife-receiving device, the power source consumption can be reduced, the conventional energy consumption problem can be improved, and the energy-saving effect can be achieved.
In addition, the tool required for extracting the tool is not affected by the weight of the tool and the moving speed. Moreover, the chain is replaced by the fixing member, and the tools can be spaced apart from each other on the fixing member, and the tools do not need to be separated by the links. By limiting, there is no need to vacate the sides of the large-sized tool, thereby effectively reducing the volume of the magazine body and installing more tools.
