[0018] The following is combined with Figure 1-3 This application is described in further detail.

[0019] The present application embodiment discloses a tool head adjustment mechanism for a plate punching machine.

One end of the fixing rod 7 passing through the fixing frame 5 is provided with a driving member for driving the tool fixing disk 6 to rotate, and the driving member is arranged inside the fixing box 4. The surface of the tool fixing disk 6 is provided with a plug hole 14. The inside of the plug hole 14 is provided with a fixing member for positioning the tool fixing disk 6, and the fixing member is arranged on one side of the punching frame 3. The fixing member includes a linear actuator 9 and an insertion rod 10. One side of the punching frame 3 is fixedly connected to the linear actuator 9 by bolts, and one end of the linear actuator 9 is fixedly connected to the insertion rod 10 by bolts, and the surface of the insertion rod 10 is inserted into the inner cavity side wall of the plug hole 14;

[0020] By adopting the above technical scheme, the output is performed through the cylinder 2 on the top of the punching machine 1, which can drive the punching frame 3, the fixing frame 5 and the tool fixing plate 6 to rise and fall, so that the punching knife 8 fixedly connected to the tool fixing plate 6 can be used to punch the plate, and the driving member provided inside the fixing box 4 can adjust the fixing rod 7 to rotate, thereby driving the tool fixing plate 6 to rotate in its fixing frame 5, so that the required punching knife 8 can be rotated downward, the punching knife 8 can be switched, and the corresponding punching knife 8 can be selected for punching. After the adjustment and switching of the punching knife 8 is completed, the linear actuator 9 can be used for output to drive the insertion rod 10 to be inserted into the insertion hole 14 of the tool fixing plate 6, which can not only play a positioning role, but also ensure the stability of the punching knife 8 during punching.

[0021] Reference Figure 1 , Figure 2 and Figure 3 The driving member includes a driving motor 11, a worm 12 and a worm wheel 13. The inner cavity side wall of the fixed box 4 is fixedly connected with the driving motor 11 by bolts. The driving motor 11 is fixedly connected with the worm 12 by an output shaft. The bottom of the worm 12 is rotatably connected to the inner cavity bottom of the fixed box 4 by a rotating shaft. The surface of the worm 12 is meshedly connected with the worm wheel 13. One side of the worm wheel 13 is rotatably connected to the inner cavity side wall of the fixed box 4 by a rotating shaft. The other side of the worm wheel 13 is fixedly connected to one end of the fixing rod 7 passing through the fixing frame 5 by bolts.

[0022] By adopting the above technical solution, the output is generated by the driving motor 11, which can drive the worm 12 rotatably connected to the bottom of the inner cavity of the fixed box 4 to rotate, so that the worm 12 can drive the worm wheel 13 meshingly connected to its surface to rotate, and the worm wheel 13 can drive the fixed rod 7 to rotate synchronously.

[0023] The implementation principle of the tool head adjustment mechanism of a plate punching machine in the embodiment of the present application is as follows: the output is made by the cylinder 2 on the top of the punching machine 1, which can drive the punching frame 3, the fixing frame 5 and the tool fixing plate 6 to rise and fall, so that the punching knife 8 fixedly connected to the tool fixing plate 6 can be used to punch the plate, and the output is made by the driving motor 11, which can drive the worm 12 connected to the bottom of the inner cavity of the fixing box 4 to rotate, so that the worm 12 can drive the worm wheel 13 meshingly connected to the surface to rotate, and the worm wheel 13 can drive the fixing rod 7 to rotate synchronously, so as to drive the tool fixing plate 6 to be fixed at its The frame 5 is rotated, so that the punching knife 8 required can be rotated to the bottom, the punching knife 8 is switched, and the corresponding punching knife 8 is selected for punching. After the punching knife 8 is adjusted and switched, the linear actuator 9 can be output to drive the insertion rod 10 to be inserted into the insertion hole 14 of the tool fixing plate 6, which can not only play a positioning role, but also ensure the stability of the punching knife 8 during the punching process. Conversely, when the punching knife 8 is switched and adjusted, the linear actuator 9 drives the insertion rod 10 to contract and pull the insertion rod 10 out of the insertion hole 14. The above-mentioned drive motor 11 can choose NEMA 17 stepper motor, NEMA 17 stepper motor is a synchronous motor that controls the movement of the rotor by applying a pulse signal. The rotation angle of the stepper motor is usually controlled by controlling the number of input pulses. Each time a pulse signal is received, the stepper motor will rotate a fixed angle, which is called the step angle. The rotation direction of the stepper motor is determined by the sequence of the input pulse signals and the direction of the current. The forward and reverse rotation of the motor can be achieved by controlling the pulse sequence and the direction of the current, thereby facilitating the adjustment and switching of the punching knife 8. The above-mentioned linear actuator 9 can use the Warner Linear K2G20-12v-BR-04 model. The linear actuator 9 contains an electric motor, which is connected to the screw through a gear box to drive the screw to rotate. When the screw rotates, the push rod connected to the screw moves linearly to achieve the extension and retraction of the actuator. The whole process does not involve any rotational movement of any parts. When the motor stops working, the friction between the screw and the nut and the design of the gear box ensure that the push rod will not move due to external forces, thereby realizing a self-locking function, thereby facilitating the movement of the insertion rod 10 and at the same time ensuring the stability of the insertion of the insertion rod 10 into the insertion hole 14. The overall operation is simple and easy, and there is no need to shut down the punching machine. The cutter head can be quickly replaced and adjusted, which can effectively ensure the stability of the cutter head during its use in the punching process and further improve its actual punching processing efficiency.
