[0037] The following is combined with Figure 1-9This application is described in further detail.

[0038] The embodiment of the present application discloses a moving beam type multi-servo indexing stamping machine.

[0039] Embodiment 1: Reference Figure 1 A movable beam type multi-servo indexing stamping forming machine comprises a supporting base 1, a fixing base 2, a stamping body 3 and a clamping mechanism 4. The supporting base 1 is a rectangular frame as a whole, the fixing base 2 is fixedly installed at one end of the supporting base 1 in the length direction, and the stamping column 3 is slidably installed on the supporting base 1 along the length direction of the supporting base 1.

[0040] Reference Figure 2 and Figure 3 The stamping body 3 includes a stamping frame 31 that slides with the support base 1, a first moving mechanism 32 that drives the stamping frame 31 to slide along the length direction of the support base 1, and a stamping mechanism 33 installed on the stamping frame 31 and used for stamping the rotor sheet.

[0041] The first moving mechanism 32 includes a first servo motor 321 fixed to one end of the support base 1, an output screw 322 connected to the output shaft of the first servo motor 321, and a moving slider 323 disposed at the bottom of the stamping frame 31 and threadedly engaged with the output screw 322. Two sets of parallel slide rails 11 are also installed on the top of the support base 1 along the sliding direction of the stamping body 3, and a slider member 324 engaged with the parallel slide rails 11 is provided at the bottom of the stamping body 3.

[0042] The stamping mechanism 33 includes a second servo motor 331 fixed in the stamping frame 31, a crank connecting rod structure 332 connected to the output shaft of the second servo motor 331, and a stamping die 333 installed at the output end of the crank connecting rod structure 332. The second servo motor 331 and the crank connecting rod structure 332 are connected by a transmission structure. The crank connecting rod structure 332 is consistent with the prior art, and the specific structure is not described in this application. The stamping die 333 is fixed to the slider of the crank connecting rod structure 332.

[0043] The stamping frame 31 has a stamping platform 311 corresponding to the crank connecting rod structure 332, and the top of the stamping platform 311 is used to fix the stamping lower die. The stamping platform 311 also has a material discharge hole 3111 connected to the stamping lower die, and a material discharge channel 312 is installed at the bottom of the material discharge hole 3111, so that the waste generated by stamping can be discharged through the material discharge channel 312.

[0044] Reference Figure 4The fixing seat 2 is fixed to the end of the supporting base 1 by bolts, and has an open slot on the side facing the stamping frame 31. The fixing seat 2 is installed with a rotating driving member 21, a positioning plate 22 connected to the output shaft of the rotating driving member 21, and a supporting plate 23 in the open slot. The rotating driving member 21 is a vertically arranged rotating motor.

[0045] The positioning disk 22 is fixed to the output shaft of the rotating motor, and the positioning disk 22 is used to cooperate and fix with the inner hole of the rotor sheet. When the rotary drive member 21 is started, the rotor sheet is driven to rotate synchronously through the positioning disk 22. After rotating a certain angle, it is punched through the punching mechanism 33 to realize the automatic punching of large rotor sheets. Among them, three sets of lifting cylinders are also installed on the top of the fixed seat 2. The piston rods of the lifting cylinders are all fixed to the bottom of the support plate 23. The support plate 23 can support the rotor sheet. At the same time, after completing the punching of a rotor sheet, the lifting cylinder is started, and the support plate 23 lifts the rotor sheet upward and disconnects it from the positioning disk 22, so that the manipulator can take out the rotor sheet for material removal.

[0046] Reference Figure 5 and Figure 6 The clamping mechanism 4 is installed on the top of the stamping frame 31 to achieve the clamping of the rotor sheet and ensure the stability of the stamping. The clamping mechanism 4 includes a clamping bracket 41 slidably installed on the top of the stamping frame 31 and a clamping head 42 lifted and installed on the clamping bracket 41.

[0047] The clamping bracket 41 is an L-shaped bracket as a whole, which includes a horizontal frame 411 and a vertical frame 412. The top of the stamping frame 31 is equipped with a slide rail that slides with the horizontal frame 411. The vertical frame 412 extends downward, and the clamping head 42 is installed at the bottom end of the vertical frame 412 to correspond to the positioning plate 22.

[0048] A third servo motor 43 for driving the horizontal frame 411 to slide is installed on the top of the stamping frame 31. The third servo motor 43 drives the horizontal frame 411 through a gear rack structure. The rack is fixed to one side of the length direction of the horizontal frame 411 along the sliding direction. A pressing and lifting cylinder 44 for driving the pressing head 42 to rise and fall is installed on the vertical frame 412. The piston rod of the pressing and lifting cylinder 44 and the pressing head 42 are connected by a guide structure 45. The guide structure 45 includes a lifting slider 451 connected to the piston rod of the pressing and lifting cylinder 44, a guide rod 452 fixed to the lifting slider 451, and a guide block 453 for guiding the guide rod 452 to rise and fall vertically.

[0049] Combination Figure 6The clamping head 42 includes a connecting frame 421 and a clamping ring 422, and the connecting frame 421 and the clamping ring 422 are integrally arranged. The connecting frame 421 is L-shaped and fixedly connected to the bottom of the guide rod 452. A rotating bearing and a clamping plate 423 fixed with the rotating bearing are installed in the clamping ring 422, and the clamping plate 423 and the top of the rotor sheet. When the clamping lifting cylinder 44 descends vertically, the clamping plate 423 is pressed on the top of the rotor sheet, and the rotating motor drives the rotor sheet to rotate, and the clamping plate 423 on the top of the rotor sheet rotates synchronously to ensure the stability of the rotor sheet.

[0050] Embodiment 2: The horizontal movement of the stamping frame 31 drives the clamping mechanism 4 to move synchronously. When replacing rotor sheets with different outer diameters, the clamping head 42 needs to be readjusted so that the axis of the clamping head 42 is coaxial with the axis of the positioning disk 22. In order to optimize the adjustment time of the clamping head 42, the present application also includes a locking mechanism 5.

[0051] The horizontal frame 411 has an installation slot 4111, and one end of the installation slot 4111 facing the vertical frame 412 is open. The horizontal frame 411 has an extension frame 413 slidably installed in the installation slot 4111. The extension frame 413 extends from the open end of the installation slot 4111 and is fixedly connected to the vertical frame 412. The area where the extension frame 413 extends out of the installation slot 4111 is defined as an extension portion 4131. The locking mechanism 5 includes a locking frame 51 and a locking assembly 52, and the locking frame 51 is mounted on both sides of the support base 1.

[0052] The locking assembly 52 includes a locking plug 521 and a locking block 522 that is lifted and installed at the end of the locking plug 521. The top of the extension portion 4131 has a plug-in slot 4132 for inserting the locking plug 521. The bottom of the locking plug 521 has a lifting slot 5211 for installing the locking block 522, and the locking plug 521 is provided with a return spring 523 on the inner top wall of the lifting slot 5211. The end of the return spring 523 is fixed to the locking block 522, wherein the locking block 522 has a guide inclined surface 5221 on the side facing the horizontal frame 411. The guiding inclined surface 5221 gradually tilts downward from the stamping frame 31 to the fixing seat 2, so that when the stamping frame 31 moves toward the fixing seat 2, the vertical frame 412 abuts against the locking block 522, which enables the locking block 522 to gradually move into the lifting groove 5211. When the locking block 522 and the plug-in groove 4132 correspond to each other, the locking block 522 automatically resets and is inserted into the plug-in groove 4132 under the action of the reset spring 523.

[0053] After completing the stamping of a group of rotor sheets, the clamping head 42 is lifted, but the gap between the clamping bracket 41 and the support plate 23 still limits the loading of the rotor sheets. The present application also installs a rotating plate 34 on the top of the stamping frame 31, and the clamping mechanism 4 is installed on the top of the rotating plate 34 as a whole. A rotating disk is installed at the bottom of the rotating plate 34, and the rotating disk is rotatably installed on the top of the stamping frame 31. A rotating drive member for driving the rotating disk to rotate is installed on the stamping frame 31, and the rotating drive member and the rotating disk are driven by a gear toothed belt.

[0054] Reference Figure 8 The plug-in slot 4132 is a strip-shaped slot, the length direction of which is parallel to the sliding direction of the stamping frame 31, and notch slots 4133 are provided on both sides of the length direction of the plug-in slot 4132, so that the rotation of the horizontal frame 411 is not likely to interfere with the locking plug 521. The side wall of the plug-in slot 4132 away from the horizontal frame 411 is an arc surface, so as to improve the smoothness of the rotation of the extension frame 413.

[0055] A push cylinder for pushing the vertical frame 412 is also installed on the stamping frame 31. The output shaft of the push cylinder is perpendicular to the sliding direction of the stamping frame 31, and the piston rod of the push cylinder is installed with a push plate 35. The length of the piston rod is adapted to the length of the extension frame 413, so that after each rotation of the extension frame 413, the push plate 35 is always located on the side of the extension frame 413 away from the horizontal frame 411. The extension frame 413 is pushed back into the horizontal frame 411 by the push plate 35 to facilitate subsequent stamping.

[0056] Reference Figure 6 and Fig. 9 In order to further improve the stability during stamping and ensure that the top surfaces of the stamping platform 311 and the support plate 23 are flush, the present application is also provided with a flush mechanism. The stamping platform 311 includes a fixed platform 3113 fixed to the stamping bracket and a lifting platform 3112 installed on the top of the fixed platform 3113. An elastic component 3114 is provided between the lifting platform 3112 and the fixed platform 3113, and the elastic component 3114 is composed of a telescopic rod and a spring sleeved on the telescopic rod.

[0057] The support plate 23 is provided with clamping rods 24 for inserting into the lifting platform 3112 on opposite sides thereof, and the clamping rods 24 are driven by a cylinder. The lifting platform 3112 is provided with insertion grooves 31121 for inserting the clamping rods 24 on both sides thereof. The insertion grooves 31121 have a driving inclined surface 31122 for abutting the clamping rods 24 on the opening side thereof facing the clamping rods 24. The height of the lifting platform 3112 under the normal state of the elastic component 3114 is greater than the top surface of the support plate 23. The fixed platform 3113 is also provided with connecting grooves for connecting the lifting platform 3112 on both sides thereof, and a clamping driving member 36 corresponding to the connecting groove is provided on the stamping frame 31. The clamping driving member 36 is a hydraulic cylinder, and its output shaft is provided with a clamping plate for abutting against the side wall of the lifting platform 3112, so as to ensure the stability of the lifting platform 3112 during stamping.

[0058] The implementation principle of a movable beam multi-servo indexing stamping forming machine in the embodiment of the present application is as follows: the rotor sheet is positioned and placed on the positioning plate 22 by a hoisting device or a manipulator, and the stamping frame 31 is moved toward the fixed seat 2 by a first moving mechanism 32, so that the distance between the stamping table 311 and the positioning plate 22 is adapted to the radius of the rotor sheet, at which time, the locking plug and the plug slot 4132 are matched; the third servo motor 43 is started, so that the clamping head 42 and the positioning plate 22 are coaxial, and the clamping head 42 is vertically lowered so that the clamping plate 423 is pressed against the rotor sheet; When it is necessary to punch rotor sheets with different outer diameters: if the outer diameter of the rotor sheet is larger than the outer diameter of the previous rotor sheet, the first servo motor 321 drives the punching frame 31 to move away from the fixing seat 2, the extension frame 413 is in a relatively static state, and the pressing head 42 and the positioning plate 22 are always in a coaxial state; If the outer diameter of the rotor sheet is smaller than that of the previous rotor sheet, the rotating plate 34 is rotated, and the extension frame 413 is reinserted into the horizontal frame 411 through the pushing plate 35, and then the clamping mechanism 4 is reset to repeat the above alignment operation.

[0059] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
