Description
Technical Field
The invention relates to a tool changing method of a machine tool, which is used for changing tools in machine tool operation.
Background
In the machining process, the tool is often required to be replaced due to the influence of the machining process, the workpiece material, the shape of the finished product and the service life of the tool, so that the machine tool is often provided with a corresponding tool changer, for example, the related structure and technology of the machine tool and the tool changer are described in taiwan TWI651155, and the tool changing processes of the machine tool of patents such as taiwan TWI488709 and taiwan TWM458268 of taiwan are also described in detail.
In the description of the patent, the tool changing process of the tool machine mainly comprises the steps of tool beating (also called pushing tool or loosening tool), tool lifting, tool changing, tool inserting and the like, and in the step of tool beating, a tool beating device is required to strike or push a pull rod at the rear end of a main shaft so as to enable the main shaft to release the tool forwards; in the step of lifting the cutter, the cutter released by the main shaft and the cutter to be replaced in the cutter storage are clamped by a cutter changing device, and the cutter is moved to be separated from the main shaft and the cutter storage; in the step of changing the cutter, the cutter is required to be rotated and changed in position by a cutter changing device; in the step of inserting the cutter, the cutter is moved and inserted into the main shaft and the cutter magazine by the cutter changing device, the cutter is clamped by the main shaft and the cutter magazine, and finally the cutter changing device can be withdrawn to the standby position, so that the cutter changing process is completed.
In the foregoing tool changing process, the action time and sequence of each device must be matched to avoid the collision machine or the tool falling, in order to ensure the correct operation of the cooperative action between each device, a signal sensing wheel may be installed in the tool changing device to measure the angle position of the input shaft or the output shaft of the transmission device of the tool changing device, so as to be compared with the start time of the tool beating device, and as a timing basis for executing the tool changing process steps, the related art may refer to, for example, fig. 7, 8 and background section of taiwan TWM518604 in china, or detailed description of taiwan TWI317312 in taiwan and TWM458268 in taiwan.
Besides the above-mentioned technique of using the signal sensing wheel to perform time sequence control on the tool changer and the tool beating device, the taiwan TWM518604 patent further describes that the related technique of detecting the angle and position of the output shaft of the tool changer by the encoding device can electronically control the working time sequence of the tool changer.
Disclosure of Invention
When the working time sequence of the tool changer is controlled by a mechanical mode and an electronic mode, the starting and the stopping of the angle and the position of the output shaft of the tool changer, the starting and the resetting of the motor in the tool changer and the like are required to be controlled, the starting and the reaching time of each action can be changed due to the influence of the hysteresis of the pneumatic or hydraulic device, the types of parts, the tolerance, the abrasion and the elastic fatigue of each device, and if the working time sequence is slightly deviated, the problems of heavy mechanical abrasion, the collision of the machine or the falling of the tool, the shutdown of the machine tool, frequent maintenance or the damage of the tool and the like are caused, so that the mechanical cost is increased.
In order to avoid the abnormal working time sequence of the tool changing device, please refer to fig. 1, when the tool changing device and the tool beating device are controlled to operate, the time sequence control can be performed by the signal sensing wheel. The typical signal sensing wheel comprises a brake signal wheel 91, a check signal wheel 92 and an origin signal wheel 93, wherein the brake signal wheel 91 is provided with a brake signal at first, the tool changer brakes and shuts down a motor of the tool changer, a user waits for starting and receiving a starting signal, the tool changer releases the brake and starts the motor, an output shaft of the tool changer acts according to a preset action time sequence diagram 94, then the brake signal wheel 91 encounters a second brake signal, the tool changer brakes and shuts down the motor and notifies the tool changer to perform tool beating, the tool changer waits for transmitting a signal of finishing the tool beating, after finishing the tool beating, the tool changer releases the brake again and starts the motor, the output shaft is driven to continue to act, then the brake signal wheel 91 encounters a third brake signal, the tool changer brakes and shuts down the motor and notifies the tool changer to perform tool pulling, the tool changer waits for transmitting a signal of finishing the tool pulling back, and after finishing the tool pulling, the tool changer releases the brake again and starts the motor of the tool changer, and drives the output shaft to continue to act and withdraw the tool changer from resetting; when the second and third braking signals are applied to the braking signal wheel, the tool changing device may slide forward under the action of mechanical inertia force, and the tool changing device may be subject to the action delay caused by the abrasion and aging of the machine part, so that the tool changing device slides forward, but the tool changing device does not complete the tool beating or broaching action, resulting in the problems of collision, tool dropping, etc., the tool checking signal wheel 92 is used for presetting the tool beating signal 921, the ending moment of the tool beating signal 921 is used as the tool checking point 922, if the tool beating completion signal of the tool changing device is not received in the period of the tool beating signal 921 or before the tool checking point 922, the tool changing device stops immediately and gives an alarm if the tool beating is not completed in the normal procedure, and the tool changing device releases the motor and starts the motor when the tool completing the tool beating completion signal is received, thereby avoiding the occurrence of collision caused by the rotation of the tool changing device when the tool is not completely released; secondly, the checking signal wheel 92 can preset the broach signal 923, take the ending moment of the broach signal 923 as the broach checking point 924, if the broach finishing signal of the broach device is not received in the period of the broach signal 923 or before the broach checking point 924, which means that the broach is not finished in the normal procedure, the machine is stopped immediately and an alarm is sent, the tool changer releases the brake and starts the motor when the broach finishing signal is received, and the spindle is withdrawn and rotated to the standby position, so that the tool is prevented from being withdrawn and falling when the spindle does not completely clamp the tool changer. The signal of the completion of the tool cutting by the tool cutting device and the signal of the completion of the tool pulling by the tool cutting device can be respectively judged by a first sensing part and a second sensing part, for example, as described in the taiwan TWM458268 patent, when the position of the tool cutting device is higher, the tool cutting device is reset upwards to complete the tool pulling, and when the position of the tool cutting device is lower, the tool cutting device is moved downwards to complete the tool cutting.
By means of the checking points 922 and 924, when the spring of the spindle is fatigued, the machine parts are worn and the gap is enlarged or the action of the tool setting device is delayed, the time spent by the spindle to finish the tool setting and the broaching may be prolonged, if the tool changing device slides and the spindle passes over the checking points and the broaching checking points when finishing the tool setting and the broaching, the machine tool can send an alarm and stop for maintenance.
However, because the spindle tool bit and the broach take different time periods, when the spindle tool bit and the broach take a relatively high speed, the tool changing device still needs to wait for the signals of the tool bit and the broach to be completed to release the brake and start the motor, and the tool changing time is prolonged to cause waste, and particularly, the commonly available tool changing time is about 2 to 2.5 seconds.
In view of the above, the present invention provides a tool changing method that can maintain smooth operation of a machine, and further shorten the tool changing time without generating heavy wear, collision, and tool drop.
In order to achieve the above-mentioned objective, the present invention provides a tool changing method of a machine tool, which is suitable for executing tool changing in the machine tool, the machine tool mainly includes a spindle, a tool bit set, a tool bit detector and a tool changing device, the tool bit set has a tool bit position and a broach position, the tool bit set approaches the tool bit detector when in the tool bit position and the spindle can loosen the tool bit, the tool bit detector detects one of the tool bit set and the spindle and outputs a tool bit signal; the knife beating group leaves the knife beating detector when the knife pulling position is reached, and the main shaft can clamp a knife; the tool changing method of the tool machine is that the tool beating group is moved to the tool beating position, the tool is taken out from the spindle and a tool magazine by the tool changing device, the tool is inserted into the spindle after the tool is interchanged, and the tool beating group is moved to the broach position.
In the above-mentioned tool changing method, after inserting the tool into the spindle and moving the tool bit set to the broach position, starting the tool changing device according to disappearance of the tool bit signal; or after the tool bit group is moved to the tool bit position, starting the tool changing device according to the occurrence of the tool bit signal.
The invention further provides a tool changing device for executing the tool machine package changing method, and the tool changing device comprises a power source, a transmission mechanism, a tool changing arm and a decoder. The transmission mechanism is provided with an output shaft, and the transmission mechanism is driven by the power source to enable the output shaft to repeatedly rotate and move according to an action sequence. The tool changing arm is arranged on the output shaft and rotates and moves along with the output shaft. The decoder is arranged on the power source or the transmission mechanism to detect the current position of the output shaft in the action sequence.
In the above tool changer, the power source may be a low inertia motor, and the transmission mechanism may be a cam worm group.
Therefore, in the tool changing process of the tool machine, the tool changing device can release the brake according to the occurrence and disappearance of the tool playing signal and start to rotate the tool changing arm or withdraw the tool changing arm, the waiting time before and after the tool playing checking point or the broach checking point is not needed, and the tool changing speed can be improved.
