Description
Technical Field
The invention relates to a tool changing method of a machine tool, which is used for changing tools during the operation of the machine tool.
Background
In the machining process of the machine tool, the machine tool is affected by the machining process, the material of the workpiece, the shape of the finished product and the service life of the tool, and the tool needs to be replaced frequently, so the machine tool is often equipped with a corresponding tool changer, for example, taiwan patent No. TWI651155 describes the relevant structure and technology of the machine tool and the tool changer, and secondly, patents such as taiwan patent No. TWI488709 and taiwan patent No. TWM458268 describe the tool changing process of the machine tool in detail.
Bearing the description of the aforementioned patent, the tool changing process of the machine tool mainly includes the steps of knife beating (also called push knife or loose knife), knife lifting, knife changing, knife inserting, etc., in the knife beating step, the knife beating device is needed to impact or push the pull rod at the rear end of the main shaft, so that the main shaft releases the knife forward; in the step of lifting the cutter, the cutter released by the main shaft and the cutter to be replaced in the tool magazine are clamped by the cutter changing device, and the cutter is moved to be separated from the main shaft and the tool magazine; in the tool changing step, a tool needs to be rotated by a tool changing device to exchange positions; in the step of inserting the cutter, the cutter is movably inserted into the main shaft and the cutter base by the cutter changing device, the cutter is clamped by the main shaft and the cutter base, and finally the cutter changing device can withdraw from the standby position to complete the cutter changing process.
In the aforementioned tool changing process, the action time and sequence of each device must be matched to avoid collision or falling of the tool, in order to ensure the correct operation of the cooperative action between the devices, a signal sensing wheel can be installed in the tool changing device to measure the angular position of the input shaft or output shaft of the transmission device of the tool changing device, so as to compare with the start time of the unclamping device, as the timing basis for executing the tool changing process steps, for example, refer to fig. 7 and 8 of taiwan patent TWM518604 and the background section, or refer to the detailed descriptions of taiwan patent i317312 and taiwan patent TWM 458268.
In addition to the above-mentioned technology of using signal sensing wheel to perform timing control on the tool changer and the tool changer, taiwan patent No. TWM518604 further describes a related technology of using a coding device to detect the angle and position of the output shaft of the tool changer, so as to electronically control the working timing of the tool changer.
Disclosure of Invention
When the working sequence of the tool changer is controlled by using a mechanical method and an electronic method, because the angle and the position of an output shaft of the tool changer need to be controlled, the motor in the tool changer needs to be started and stopped, and the tool changer needs to be started, cut and reset, and other actions, the starting and reaching time of each action may be influenced by the delay of an air pressure or an oil pressure device, the part types, the tolerance, the abrasion and the elastic fatigue of each device and change, if the working sequence has slight deviation, the problems of mechanical heavy pressure abrasion, machine collision or tool falling are easy to occur, the machine tool stops, the maintenance is frequently needed or the tool is damaged, and the mechanical cost is increased.
To avoid the working timing of the tool changer becoming abnormal, please refer to fig. 1, when controlling the operation of the tool changer and the tool changer, the timing control can be performed by the signal sensing wheel. A typical signal sensing wheel comprises a brake signal wheel 91, a checking signal wheel 92 and an origin signal wheel 93, the brake signal wheel 91 initially has a brake signal, the tool changer brakes and closes a motor of the tool changer, the tool changer receives a start signal after being started by a user, the tool changer releases the brake and starts the motor, an output shaft of the tool changer moves according to a preset action timing chart 94, the brake signal wheel 91 encounters a second brake signal, the tool changer brakes and closes the motor and informs the tool changer to perform tool cutting, the tool changer returns a signal of completing the tool cutting after the completion of the tool cutting, the tool changer releases the brake again and starts the motor to drive the output shaft to continue to move, the brake signal wheel 91 encounters a third brake signal, the tool changer brakes and closes the motor and informs the tool changer to perform tool drawing, and the signal of completing the tool drawing is waited for the tool cutting device to return a signal of completing the tool drawing, after the broach is pulled, the tool changer releases the brake again and starts a motor of the tool changer to drive the output shaft to continue to act so as to withdraw the tool changer for resetting; when the brake signal wheel is used for the second brake signal and the third brake signal, the tool changing device can slide forwards under the action of mechanical inertia force, the hitting device may be influenced by wear and aging of the machine member to delay the operation, so that the tool changer has slid forward and the hitting device has not completed hitting or pulling the tool, causing problems such as hitting and falling of the tool, the hitting signal 921 can be preset by the checking signal wheel 92, the ending moment of the hitting signal 921 is used as the hitting checking point 922, if the signal that the knife striking of the knife striking device is completed is not received within the period of the knife striking signal 921 or before the knife striking verification point 922, the knife striking device stops immediately and gives an alarm when the knife striking is not completed in a normal program, the knife changing device releases the brake and starts a motor when receiving the signal that the knife striking is completed, and the cutter is changed in a rotating mode, so that the phenomenon that the knife striking is caused when the knife changing device does not completely release the knife can be avoided; secondly, the checking signal wheel 92 can preset a broach signal 923, the finishing moment of the broach signal 923 is used as a broach checking point 924, if the broach signal 923 is not received in the period of the broach signal 923 or before the broach checking point 924, the broach checking signal represents that the broach is not finished in a normal program, the machine is immediately stopped and an alarm is sent, the cutter changing device receives the broach finishing signal, the brake is released, the motor is started, the cutter changing device retreats and rotates to a standby position, and the phenomenon that the main shaft retreats and falls off when the main shaft does not completely clamp the cutter changing device can be avoided. The signal indicating that the unclamping operation of the unclamping device is completed and the signal indicating that the broaching operation is completed can be determined by a first sensing portion and a second sensing portion, respectively, as described in taiwan patent No. TWM458268, for example, when the unclamping device is at a higher position, the unclamping device is reset upward to complete the broaching, and when the unclamping device is at a lower position, the unclamping device is moved downward to complete the unclamping.
By means of the knife hitting and checking point 922 and the broach checking point 924 set up by the checking signal wheel 92, when the spindle spring is exhausted, the machine member is worn and the gap is enlarged or the action of the knife hitting device is delayed, the time spent by the spindle to finish the knife hitting and the broach may be lengthened, if the tool changing device slides and the spindle finishes the knife hitting and the broach and passes the knife hitting and checking point and the broach checking point, the machine tool can send out an alarm to stop the machine for checking.
However, since the time spent on the spindle unclamping and broaching is different, when the spindle unclamping and broaching is faster, the tool changer still has to wait for the completion of the unclamping and broaching signal to release the brake and start the motor, and the tool changing time is prolonged, which is a waste, and particularly, the achievable tool changing time is about 2 to 2.5 seconds.
Accordingly, one objective of the present invention is to provide a tool changing method, which can maintain smooth mechanical operation and further shorten the tool changing time without generating heavy pressure abrasion, collision, or falling of the tool.
In order to achieve the above object, the present invention provides a tool changing method for a machine tool, which is suitable for performing tool changing on the machine tool, the machine tool mainly comprises a main shaft, a tool changer, a tool detector and a tool changer, wherein the tool changer comprises a tool position and a tool pulling position, the tool changer is close to the tool detector when in the tool position, the main shaft can release the tool, and the tool detector detects one of the tool changer and the main shaft and outputs a tool signal; when the cutter group is at the broach position, the cutter group leaves the cutter detector and the main shaft can clamp the cutter; the tool changing method of the machine tool comprises the steps of firstly moving the cutter beating group to the cutter beating position, taking a cutter from the main shaft and a cutter warehouse by the tool changing device, inserting the cutter into the main shaft after the cutter is exchanged, and moving the cutter beating group to the cutter pulling position.
In the tool changing method, after a tool is inserted into the spindle and the tool striking set is moved to the tool drawing position, the tool changing device is started according to the disappearance of the tool striking signal; or after the cutter beating group moves to the cutter beating position, the cutter changing device is started according to the appearance of the cutter beating signal.
The invention further provides a tool changer which is used for executing the tool machine package changing method. 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 cutter 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 tool changer, the power source may be a low inertia motor, and the transmission mechanism may be a cam worm set.
Therefore, in the process of tool changing of the tool machine, the tool changing device can remove the brake and start to rotate for tool changing or rotate the tool changing arm to withdraw according to the appearance and disappearance of the tool beating signal, does not need to wait for a tool beating check point or a tool drawing check point, can save the waiting time before and after the past tool beating check point and tool drawing check point, and improves the tool changing speed.

TWM458268, TW465421 and TW 375213. The knife flywheel 2 further has a sensing block 22, and the sensing block 22 is fixed on the push rod 21 and moves up and down along with the push rod 21. In other possible embodiments of the present invention, the sensing block 22 can be disposed at other positions in the pull rod 11 or the main shaft and the broaching set, and can move up and down during the broaching and broaching processes, so as to obtain the similar functions as those of the present embodiment.
The tool setting detector 3 and the broach detector 4 are arranged on the main shaft 1 or the tool setting group 2, the tool setting detector 3 and the broach detector 4 are respectively positioned at the side of the sensing block 22 and point to the sensing block 22, when the push rod 21 moves downwards to the tool setting position, the sensing block 22 moves downwards to be close to the tool setting detector 3 and just positioned in front of the tool setting detector 3, the tool setting detector 3 detects the sensing block 22 and outputs a tool setting signal, which represents that the main shaft really finishes releasing the tool; when the push rod 21 moves upward to the broach position, the sensing block 22 moves upward away from the tapping detector 3, approaches the broach detector 4 and is just in front of the broach detector 4, the tapping detector 3 stops outputting the tapping signal and the broach detector 4 detects the sensing block 22 and outputs the broach signal, which represents that the spindle has indeed completed resetting and clamping the tool.
The tool changer 5 can be used for taking tools from the spindle 1 and the tool magazine 6, rotating and interchanging two groups of tools, and then inserting the tools into the spindle and the tool magazine, in detail, the tool changer 5 includes a power source 51, a transmission mechanism 52, a tool changing arm 53 and a decoder 54, the power source 51 is a motor, preferably a low inertia motor, and can reduce the position inaccuracy caused by the inertia of the motor when starting and closing the motor, the transmission mechanism 52 is a cam worm set, and is directly or indirectly connected to the power source 51 via a speed reducer, the transmission mechanism 52 has an output shaft 521, the tool changing arm 53 is fixed on the output shaft 521, the transmission mechanism 52 is driven by the power source 51, the output shaft 521 drives the tool changing arm 53 to repeatedly execute the rotation and movement required by the tool changing 7 between the spindle 1 and the tool magazine 6, and the specific structure of the transmission mechanism 52 can refer to, for example, taiwan i TWI317312, In the details of taiwan patent nos. TW338014 and TWM458268, the decoder 54 is connected to the output shaft 521 of the transmission mechanism 52, or to other components in the transmission mechanism 52, so as to directly or indirectly detect the current position of the output shaft 521 and output a position signal according to the position of the output shaft 521. Since the power source 51 is connected to the transmission mechanism 52, the angular position of the power source 51 and the position of the output shaft 521 have a certain relative relationship, in other possible embodiments of the present invention, the decoder 54 can be connected to the power source instead, and can also indirectly detect the current position of the output shaft and output a position signal.
The magazine 6 is, for example, a disc magazine, and can supply a tool to the tool changer 5 to perform tool changing, and specifically, the magazines described in patents such as taiwan TW445919, taiwan TWI310715, and taiwan TWM565626 can be used as the magazine 6 in the present invention, and if the size and the installation position of the magazine can be matched with the tool changer 5, it is not impossible to use another type of magazine other than the disc magazine.
Referring to fig. 2 and 3, the tool changing method of the machine tool of the present invention mainly includes the steps of positioning the tool arm, striking the tool, lifting the tool, changing the tool, inserting the tool, and withdrawing the tool arm. In the tool arm positioning step 81, the tool changer is started, the tool changing arm 53 is rotated to enable two ends of the tool changing arm to be respectively arranged below the tool magazine 6 and the spindle 1, then the tool changer is closed and the brake is started, the tool changing arm 53 is arranged below the tool magazine 6 and the spindle 1, and other signals are waited for; in the unclamping step 82, the unclamping group 2 is started, the push rod 21 moves downwards to impact or push the pull rod 11 of the main shaft, the main shaft 1 releases the cutter 7 forwards, and after the push rod 21 moves downwards, the unclamping detector 3 detects the sensing block 22 and outputs a unclamping signal, wherein the unclamping group 2 is started without waiting for the cutter changing arm 53 to reach the lower part of the main shaft 1 and starting the unclamping group 2 after the brake of the cutter changing device 5 is started, or the unclamping group 2 is started in advance before the brake of the cutter changing device 5 is started, so that the unclamping group 2 immediately finishes unclamping after the cutter changing arm 53 reaches the lower part of the main shaft 1; in the tool lifting step 83, when a tool hitting signal occurs, the brake is released and the tool changer 5 is started, the tool changer 5 is driven to clamp the tool 7 released by the spindle 1 and the tool to be replaced in the tool magazine 6 to move downwards to be separated from the spindle 1 and the tool magazine 6, wherein the tool changer 5 is started, specifically, the power source 51 in the tool changer 5 is started, and the motor is started in this embodiment; in the tool changing step 84, the tool changing device continues to drive the tool 7 to rotate, and the tool from the tool magazine 6 and the tool 7 released by the spindle 1 are rotated to exchange positions; in the step 85 of inserting a tool, the tool changer 5 inserts the tool 7 into the spindle 1 and the tool magazine 6, closes the tool changer and starts the brake, and starts the unclamping group 2 to move the push rod 21 upward away from the pull rod 11, the pull rod 11 is reset upward immediately, the spindle 1 clamps the tool 7, after the push rod 21 moves upward, the sensing block 22 leaves the unclamping detector 3 to cause the unclamping signal to disappear, and then the unclamping detector 4 detects the sensing block 22 to output the unclamping signal; in the tool arm withdrawing step 86, when the tool hitting signal disappears, the brake is released and the tool changer 5 is started, and the tool changing arm 53 of the tool changer 5 is driven to withdraw to the standby position, thereby completing the tool changing process.
In the steps, the occurrence of the cutter beating signal represents that the cutter beating group moves to the cutter beating position, the pull rod does move downwards, the main shaft releases the cutter, and in the cutter lifting step, the brake is released and the cutter changing device is started when the cutter beating signal occurs, the cutter changing device takes the cutter to start moving while releasing the cutter, so that the waiting time can be saved, all parts can be correctly connected in the cutter transferring process, and the cutter changing speed can be accelerated without colliding and falling the cutter.
In the above steps, disappearance of the knife striking signal represents that the knife striking group leaves the knife striking position, the pull rod is acted by a reset device in the main shaft, the knife striking group can reset upwards immediately although the position is uncertain, the knife is clamped, and the knife arm withdrawing step is to remove the brake and start the knife changing device when the knife striking signal disappears.
In addition, in the above-mentioned knife forging step, the start of the knife forging set can be started in advance before the knife changing arm reaches the lower part of the main shaft, and the knife forging set is started in advance by 0.1 to 0.4 seconds, in other words, at the moment of starting to move the knife forging set towards the knife forging position, the knife changing device does not clamp the knife yet, so that the knife changing arm reaches the lower part of the main shaft and clamps the knife almost simultaneously to complete knife forging, thus not only saving the time for the knife changing arm to wait for completing knife forging, but also having shorter time for the knife changing device to brake and close the power source, further reducing the inertia lag phenomenon caused by starting after the motor is closed, and improving the knife changing speed.
It should be noted that the up and down directions mentioned in the present embodiment are used to describe the relative position relationship between the components and parts in the present embodiment, and under the condition that the tool changing method and the tool changing device of the machine tool of the present embodiment are not changed in structure, the machine tool simply tilts, turns over or changes the corresponding directions, which all belong to feasible specific embodiments.
Therefore, the tool changing method of the tool machine can be applied to the tool machine, the starting time of the tool changing device is timely advanced by means of the appearance and disappearance of the tool breaking signal, the tool changing time is shortened, the shortest tool changing time which can be achieved is about 1.26-1.34 seconds and is different, compared with the tool changing time which is required by using a signal sensing wheel to manage the tool changing working time sequence in the past and is 2-2.5 seconds, the tool changing time can be saved by about 33% -49%, and the effect is excellent.
The foregoing description is intended to be illustrative rather than limiting, and it will be appreciated by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the invention as defined in the appended claims.
