Description
Technical Field
The invention relates to a cutter vehicle, in particular to an intelligent cutter changing system with double intelligent cutter holders and a cutter changing method thereof.
Background
A tool is an indispensable machining tool for a CNC numerical controller, and the tool to be machined is different depending on the machining method, the workpiece to be machined, and the CNC numerical controller. In general, a machining factory generally has a plurality of machining tools and various workpieces to be machined, and when the service life of a tool needs to be considered, because the types of tools used in the general machining factory are very many, much manpower and time are consumed in management, the time and the timeliness of tool changing can be grasped, the wrong tool is avoided, and the service life of the tool is considered.
Some tool carts, tool management systems and tool magazine management systems are available on the market, wherein tools taken out from a tool magazine or tools to be returned to the tool magazine for storage are all placed on the tool carts for convenient transportation; the tool car sends the tool taken out from the tool magazine to a processing machine tool on site, the tool is manually set on the processing machine tool, the tool unloaded from the processing machine tool is placed on the tool car, and the tool car returns to the tool magazine, so the tool on the tool car needs to be managed and recorded to prevent the tool from being taken by mistake. The existing tool car on the market does not have the function of checking the tools, so that when the tool car is used for loading and unloading the tools, the manpower is often needed to record the upper and lower tools and determine whether the upper and lower tools are correct, the tool changing process and tool management are time-consuming and easy to generate errors, the problems of the tool changing process and tool management of the tool car are caused, and even the problems of a tool management system and a tool magazine management system are caused, and therefore, the problem of how to solve the tool changing process and tool management of the tool car is urgent.
In addition, since there are many processing machines in a machining factory, if a tool is replaced with only one or a small number of tool carts, when the tool cart moves to a processing machine where upper and lower tools are required to perform work, another processing machine where upper and lower tools are required must wait for the previous processing machine to complete the tool replacement, and then wait for the tool cart to move to the next processing machine where upper and lower tools are required to perform the tool replacement, so that the tool changing operation for the upper and lower tools can be performed, thereby increasing the time for waiting for the tool changing operation. However, if more tool carts are purchased to overcome this problem, not only will more space be occupied in the processing plant, causing inconvenience in movement, but also the cost will be increased by installing more expensive tool carts.
Accordingly, how to provide an intelligent tool car and a tool changing method thereof has become a topic of urgent research.
