Description

TECHNICAL FIELD

[0001] The utility model is applied to the technical field of tool machine, especially a sliding block automatic adjusting device which can automatically and quickly adjust the die mounting height and the die mounting height limit of the sliding block. BACKGROUND

[0002] Generally, tool machines with sliding blocks, such as punch presses and powder metallurgy machines, need to adjust the sliding blocks of the tool machines to the preset positions for the installation of different molds, so as to facilitate the subsequent mold installation operation. However, in order to check the indicator between the impact arm driving the upper mold of the punch press and the lower mold of the bed, the indicator can provide protection for the machine parts and the mold from improper stamping when the punch stroke is corrected and detected after changing the mold set, and the setting of the punch stroke can obtain data correction and accurate effect. The punch press special machine can produce various products with different appearances by setting different molding mold sets through gravity stamping; however, it is found that the punch stroke distance between the upper and lower molds of the entire mold set must be re-detected after installation, because the punch stroke distance required by each mold set is different, and it is necessary to correct and detect at any time. The general inspection method is to first drive the upper mold downward by the impact arm, and then adjust the distance length by manual visual inspection. Although the punch stroke distance has been tested, it is still necessary to test the products after stamping to see if they have reached the molding standard. As a result, not only does manual visual inspection cause great errors, but it also takes a lot of time to detect, and even when testing the products, the quality stability cannot be maintained due to different quality requirements of each operator, and the previous improper punch stroke setting may cause rapid wear or damage of the mold set. Such repeated problems are a great trouble for the industry, and it is a great pain to bear.

[0003] Therefore, in order to display the die height and the die limit on the machine tool, a slider indicator (or die height indicator) is developed. The slider indicator is initially a mechanical structure, such as the Taiwan patent publication numbers TW 427218 and TW 433092 obtained by the inventor in the early years. Due to the changes in the technology era, the industry has also developed electronic slider indicators to provide industrial use, such as the CN 104553042 patent publication number. However, the aforementioned slider indicators only provide the operator with the current die height and the upper and lower limits of the die. The operator still needs to move back and forth on the machine tool slider to adjust and test in order to adjust the optimal die height and limit, which indeed wastes time and cost. The aforementioned slider indicators still have some deficiencies. Due to the uncertainty in product manufacturing, the mold may need to be replaced due to the manufacturing schedule. However, after replacing the different molds, the slider position needs to be adjusted again. Since the parameters of the molds that have been adjusted cannot be recorded, the adjustment time is affected, resulting in waste of processing time. At the same time, during the adjustment process, the slider position can only be adjusted manually, which also increases the adjustment time. There is a lack of a slider that can be precisely and automatically adjusted to the required die height and die limit. Practical new type content

[0004] In view of the deficiencies of the prior art, the purpose of the present application is to provide a new slider automatic adjustment device with innovation, which can solve the problem that the existing die indicator can only provide display function and cannot automatically adjust the slider to move to the die height and die limit. The problem of low production speed due to the inability of the slider to automatically improve the adjustment efficiency in actual use is solved. By automatic adjustment, the slider can reach the preset set value position more accurately and quickly. This way of adjusting the slider position can effectively shorten the adjustment time. By remembering the parameters of the set values of the sliders required by different molds, the efficiency of adjusting the slider is increased, and the lead time of the machining operation is greatly shortened.

[0005] In order to achieve the above purpose, the present application adopts the following technical solutions: a slider automatic adjustment device for setting on a machine tool, and the machine tool has a slider and a motor for driving the linear movement of the slider, which includes a slider indicator and a slider controller.

The first power source provides power for the slider indicator. The sensing element senses the moving position of the slider to provide information received by the first processor chip. The first display panel displays the current value of the corresponding position of the slider and is connected to the slider controller in wired or wireless manner.

[0007] The slider controller includes a housing, a display panel, and a control module. The housing is arranged on one side of the machine tool and has a shell. The control module is arranged in the shell and is electrically connected to the display panel. The control module includes a power source, a processor chip, a communication chip, a forward rotation motor relay, a reverse rotation motor relay, and a reverse rotation motor relay. The power source supplies power to the control module. The processor chip is electrically connected to the display panel. The display panel displays various numerical outputs and information of the control module and pre-inputs a preset set value to the processor chip. The control module controls the corresponding lifting action of the slider. The communication chip is used to electrically connect the first communication chip of the slider indicator. The numerical value of the slider indicator can be transmitted to the processor chip of the control module through the communication chip. The numerical value parameter of the slider is displayed through the display panel. The forward rotation motor relay is connected to the processor chip and the driving motor of the machine tool, respectively. The processor chip controls the driving motor to rotate forward through the forward rotation motor relay. The reverse rotation motor relay is connected to the processor chip and the driving motor of the machine tool, respectively. The processor chip controls the driving motor to rotate reversely through the reverse rotation motor relay. When the automatic adjustment mode is performed, the slider can be moved to the die height corresponding to the set value and the die limit position through the forward rotation motor relay and the reverse rotation motor relay. The module adjustment switch is connected to the processor chip to control the opening or closing of the control module.

[0020] As Figures 1 to 8The slider automatic adjustment device is used for connecting to a machine tool (not shown in the figure).

[0021] The machine tool comprises a driving motor (not shown in the figure) for driving a slider (not shown in the figure) to move in a vertical direction.

[0022] The slider automatic adjustment device comprises a slider indicator 10 and a slider controller 20.

[0023] The slider indicator 10 comprises a first display panel 11, a sensing element 12, a first processor chip 13, a first power source 14 and a first communication chip 15. The first power source 14 provides power for the slider indicator 10, and the sensing element 12 can sense the moving position of the slider. The sensing element 12 can be selected from a sensor, preferably an angle sensor with a speed meter and an inclination angle sensing module. The prior art uses a permanent magnet and a signal acquisition circuit arranged in the slider indicator 10 to acquire the angle change information of the permanent magnet. The permanent magnet is connected to a driving shaft or a steel cable to rotate and connect with a driving motor of the machine tool. A signal line is connected to the communication chip 232 and the first processor chip 13 of the slider controller 20, and the first display panel 11 displays the current value 110, the upper limit value 111 and the lower limit value 112 of the slider on the machine tool. The signal acquisition circuit is a magnetic rotary encoder, which is not described in detail here.

[0024] The slider controller 20 comprises a housing 21, a display panel 22 and a control module 23.

[0025] The housing 21 of the slider controller 20 is mounted on one side of the machine tool. The housing 21 can be a human-machine interface control box of the machine tool. The housing 210 is internally assembled with a control module 23. The front surface of the housing 210 is provided with at least one button 211 or knob 212.

[0026] The control module 23 is arranged in the housing 210. The control module 23 comprises a power supply 230, a processor chip 231, a communication chip 232, a forward rotation motor relay 233, a reverse rotation motor relay 234, a module adjustment switch 235, a manual forward rotation motor switch 236 and a manual reverse rotation motor switch 237.

[0027] The power supply 230 supplies power to the control module 23.

[0028] The processor chip 231 is electrically connected to the display panel 22, the control module 23 and the keys 211, and the display panel 22 is used to display various numerical outputs and messages provided by the control module 23, and the processor chip is used to automatically move the current value of the slider to the same set value as the upper and lower limit values of the mold height. This can be achieved by using a common comparison circuit, or by using an MCU controller or a PID controller to achieve a closed loop. For example, the current value 110 of the slider, the upper limit value 111 and the lower limit value 112 are displayed at the same time, and the corresponding functions of the keys 211 and the knobs 212 are indicated. Further, the processor chip 231 and the communication chip can be arranged on the same circuit board. In order to effectively control the motor for linear movement of the slider, the processor chip 231 can use a feedback circuit to drive the motor relay, thereby achieving control of the motor operation.

[0029] In other embodiments, the display panel 22 can be a touch display panel, and the keys 211 can be directly displayed on the touch display panel.

[0030] The present embodiment can control the functions of the processor chip 231 through the keys 211, and the processor chip 231 can input a set value (such as the current value and the upper and lower limit values of the mold height shown in Figs. 1 and 2) through the keys 211. The set value is the desired movement position of the slider to the optimal processing position of the mold, so that the processor chip 231 can easily control the actions of the slider. In addition, the processor chip 231 has functions such as language switching, metric and imperial switching, display of four digits (i.e. the precision can be set to millimeters) or five digits (i.e. the precision can be set to microns), abnormal fault alarm and warning reminder, etc. When the transmission shaft or steel cable connected to the permanent magnet in the slider indicator 10 may be broken, the processor chip 231 of the control module receives an abnormal signal, the display panel 22 displays the ALARM abnormal fault information, and the slider controller 20 automatically shuts down and cannot be operated again, providing immediate maintenance for the operator. Figure 7 Figure 8 In addition, the processor chip 231 also has a steering switching function (commonly known as R-type or L-type switching), which is set to change to the left or right side according to the gear steering of the tool machine. Different tool machines may produce different forward or reverse rotations corresponding to the different rising or falling of the slider. The processor chip 231 of the present embodiment has the function of selecting the steering switching, which can be switched to the required steering according to the needs of the operator.

[0031] In addition, the processor chip 231 also has a steering switching function (commonly known as R-type or L-type switching), which is set to change to the left or right side according to the gear steering of the tool machine. Different tool machines may produce different forward or reverse rotations corresponding to the different rising or falling of the slider. The processor chip 231 of the present embodiment has the function of selecting the steering switching, which can be switched to the required steering according to the needs of the operator.

[0032] ​The communication chip 232 of the slider controller 20 is used for electrically connecting the first communication chip 15 of the slider indicator 10 to transmit messages, and can adopt RS485 communication and RS232 communication to communicate with the accessories of the slider indicator 10, so that the setting parameter value can be transmitted to the processor chip 231 of the control module 23 through the communication chip 232, and the current value of the slider position is displayed through the display panel 22.

[0033] The forward rotation motor relay 233 is connected to the processor chip 231 and the driving motor of the machine tool respectively, so that the processor chip 231 controls the motor to rotate forward during driving through the forward rotation motor relay 233.

[0034] The reverse rotation motor relay 234 is connected to the processor chip 231 and the driving motor of the machine tool respectively, so that the processor chip 231 controls the motor to rotate reversely during driving through the reverse rotation motor relay 234, and the slider is moved to the position corresponding to the setting value through the cooperation of the forward rotation motor relay 233 and the reverse rotation motor relay 234.

[0035] The module adjustment switch 235 is electrically connected to the processor chip 231 respectively, so as to control the control module 23 to be turned on or turned off.

[0036] The manual forward rotation motor switch 236 is connected to the processor chip 231 and the driving motor of the machine tool respectively, so that the manual forward rotation motor switch 236 is manually controlled to control the motor to rotate forward during driving through the processor chip 231.

[0037] The manual reverse rotation motor switch 237 is connected to the processor chip 231 and the driving motor of the machine tool respectively, so that the manual reverse rotation motor switch 237 is manually controlled to control the motor to rotate reversely during driving through the processor chip 231, so as to move the slider to the position corresponding to the setting value through the cooperation of the manual forward rotation motor switch 236 and the manual reverse rotation motor switch 237.

[0038] As shown in Figures 1 to 3 The slider automatic adjustment device of the utility model, which comprises:

[0039] A processing unit A is electrically connected to a display panel 22, and a setting value (not shown in the figure) is input in the processing unit A, and the setting value is the best processing position of the upper limit value 111 and the lower limit value 112 required by the slider to move.

[0040] An automatic adjustment unit B is controlled by the processing unit A, and is used for automatically adjusting the slider position of the machine tool to move the slider to the position corresponding to the setting value.

[0041] A manual adjustment unit C is used to manually adjust the slide position of the machine tool by manually controlling the processing unit A, so as to move the slide to the position corresponding to the set value.

[0042] A everything changing unit D controls whether the processing unit A is started.

[0043] As shown in Figures 1 to 3 When the slide automatic adjustment device of the present embodiment performs the slide correction of the machine tool, it includes: switching the module adjustment switch 235 to start to start the control module 23. A preset set value (not shown in the figure) is input in advance in the slide controller 20. The set value is the set value of the upper and lower limit values of the machining position of the slide moving to the die mounting height.

[0044] When the control control module 23 starts the automatic adjustment mode, for example, by controlling the button 211 or the knob 212, the processor chip 231 controls the driving motor of the machine tool to operate, and the processor chip 231 transmits messages to the first communication chip 15 of the slide indicator 10 through the communication chip 232, moves the slide position to the same set value as the current value 110 and the upper limit value 111 or the lower limit value 112 of the slide, and approaches the set value. The processor chip 231 controls the driving motor to stop operating.

[0045] Then, the processor chip 231 controls the forward motor relay 233 or the reverse motor relay 234 to intermittently and slowly control the driving motor, fine-tune the slide position, and move the slide to the position corresponding to the set value required by the slide controller 20. In addition, when the operator of the machine table accidentally inputs a value greater than the upper limit value 111 or the lower limit value 112 allowed by the slide, the processor chip 231 controls the forward motor relay 233 or the reverse motor relay 234 to control the driving motor to be inactive, effectively avoiding the problem of machine damage caused by improper human operation.

[0046] If there is an error value between the preset set value and the actual required position at this time, the operator can also adjust the set value input by the slide indicator 10 according to the above description, and repeat the above steps to move the slide to the position corresponding to the set value of the upper limit value 111 or the lower limit value 112.

[0047] When the control control module 23 starts the manual adjustment mode, for example, by controlling the button 211 or the knob 212.

[0048] At this time, the operator can visually control the manual forward motor switch 236 or the manual reverse motor switch 237 in a long press or a short press manner. Long pressing the manual forward motor switch 236 or the manual reverse motor switch 237 can continuously control the driving motor of the machine tool to rotate forward or reverse by the processor chip 231, so as to continuously move the slider to rise or fall. Short pressing the manual forward motor switch 236 or the manual reverse motor switch 237 can intermittently control the slider to rise or fall, so as to move the slider to the position corresponding to the optimal set value.

[0049] When the slider of the machine tool moves to the position corresponding to the optimal set value, the control processor chip 231 can record the related value, that is, record the set value corresponding to the correction.

[0050] In the future, when the same mold is used, the set value recorded in the processor chip 231 can be called out to directly adjust the slider, so that the adjustment time can be greatly reduced, and the manufacturing time can be relatively reduced.

[0051] When the correction of the set value is completed, the control module adjustment switch 235 can be switched to off to close the control module 23, so as to avoid the misoperation during subsequent machining work, and has the protection effect.

[0052] The utility model has been described by the above embodiment and the change example, all the embodiments and the change example of the utility model are only exemplary, various changes of the slider automatic adjustment device with the above characteristics are covered by the utility model based on the utility model essential spirit and the scope.
