A stop mechanism for changing tools on a machine tool head and a method of using the same

Abstract

The invention relates to the field of machine tool tool change systems, in particular to a stop mechanism for tool change of a machine tool head and a method for using the same, including a fixing plate, a bracket is fixed on the fixing plate, and a motor for driving the tool head is fixed on the bracket. The output shaft end of the motor is fixedly connected to the drive shaft, and the drive shaft is fixedly connected to the center of the cutterhead. The drive shaft is provided with a locking mechanism for locking the drive shaft, and the locking mechanism is provided with an unlocking mechanism. The mechanism is connected by transmission, and the unlocking mechanism is used to release the locking state of the drive shaft by the locking mechanism. The locking mechanism is provided with a cooling and lubricating mechanism for cooling and lubricating the locking mechanism, and the cooling and lubricating mechanism is connected by transmission to the locking mechanism. This kind of stop mechanism and its usage method for tool changing of the machine tool head can overcome the moment of inertia of the cutter head, thereby protecting the drive shaft and the motor, reducing the cost of equipment, and driving the cooling and lubrication mechanism through the locking mechanism. The locking mechanism is cooled and lubricated.

Description

Technical field [0001] The present invention relates to the field of machine tool change systems, and methods of using the stopper mechanism used in particular to a machine tool cutter tool change. Background technique [0002] Machine tool changing systems peripheral wall of the cutter fixedly mounted a plurality of tools, since the cutter motor is required during a tool corresponding to the rotation of the tool holder at the transducer, then the use of the tool holder on changing the cutter blade with the spindle each seat of the tool changer, after the cutter head is driven motor having a moment of inertia, so the connecting shaft rotational inertia of the motor and the cutter will produce torsional stress in the stop, on the one hand so that the cutter stop position is incorrect, resulting in change ATC holder failed failure, reduce the efficiency of the machine; on the other hand connected to the torsion generated damage, reduced service life, cost increase, and moment of in...

AI Technical Summary

Problems solved by technology

[0002] Multiple tools are fixedly installed on the peripheral wall of the cutter head in the tool change system of the machine tool. Since the cutter head needs a motor to rotate the corresponding tool to the tool changer when changing the tool, and then use the tool changer to connect the tool on the cutter head to the spindle tool. The tools on the seat are mutually converted, and the cutter head has a moment of inertia after being driven by the motor, so the moment of inertia will generate torsional stress on the connecting shaft between the motor and the cutter head when it stops, on the one hand, the stop position of the cutter head is inaccurate, resulting The failure of the tool holder to change the tool causes a fault, which reduces the working efficiency of the machine tool; on the other hand, it causes torsional damage to the connecting shaft between the motor and the cutter head, which reduces the service life and increases the cost of use, and the moment of inertia of the cutter head is passed through the connection between the motor and the cutter head The shaft transmission to the inside of the motor damages the internal structure of the motor and reduces the service life of the motor, which increases the cost of the entire tool change system dramatically.
