[0001] The present invention relates to the technical field of end cover punching, in particular to a robot micro motor end cover punching device and a use method thereof. Background Art

[0002] Modern robots rely heavily on micromotors. For example, brushless micromotors, used as the "precision joints" of robots, have a penetration rate exceeding 65% in collaborative robot joint modules. Boston Dynamics' latest all-electric Atlas robot uses an electric drive solution instead of a hydraulic system, demonstrating the advantages of micromotors in improving flexibility and commercialization potential. Furthermore, dexterous hands are key to the generalization capabilities of humanoid robots, requiring micromotors to achieve high-precision manipulation.

In order to achieve the above purpose, the present invention provides the following technical solutions: a robot micro motor end cover punching device, including a base, and a drilling machine is provided on the upper side of the base, a ring seat is fixedly connected to the inside of the base, and an inner support for supporting the end cover is provided in the middle of the ring seat, the inner ring of the ring seat is provided with a plurality of sliding grooves, and a card block is slidably connected in the sliding groove, a spring is provided in the sliding groove, and the spring pushes the card block to slide outward along the sliding groove, the top of the card block is provided with an oblique opening, and the bottom of the card block is fixedly connected to a card plate, and the bottom of the card plate is fixedly connected to a press pin.

[0009] The inner bottom wall of the base is provided with an annular groove, and a ring frame is rotatably connected in the annular groove. The top of the ring frame is provided with an annular array of bevel teeth that match the pressure pin, and a plurality of magnetic blocks that match the end cover are fixed on the ring frame.

[0010] Preferably, a side surface of the card plate is provided with a card slot that matches the end cover.

[0011] Preferably, a spring piece is fixedly connected to the oblique opening, and a through hole is opened on the oblique opening to connect the card plate and the card slot. A latch is slidably connected in the through hole, and the top end of the latch is fixedly connected to the spring piece.

[0012] A first oblique edge for engaging the end cover is cut on one side of the bottom end of the latch pin opposite to the slot opening, and a second oblique edge for releasing the end cover is cut on one end of the bottom end of the latch pin opposite to the slide slot.

[0016] Preferably, the top of the inner support is provided with a plurality of rolling balls that cooperate with the end cover.

[0017] A method for using a robot micro motor end cap punching device comprises the following steps:

[0018] S1. Place the end cap of the robot micro motor to be processed into the ring seat and press it down. The end cap squeezes the card block along the oblique mouth and retracts into the slide slot until the end cap falls on the inner support. At this time, the card block resets and pops out to be stuck on the upper side of the end cap, cooperating with the inner support to limit the up and down movement of the end cap. When the card block pops out, the card plate at its bottom is simultaneously pressed against the side of the end cap to limit the translation of the end cap.

[0019] S2. After the end cover is completed, the slide moves along the rotating frame to drive the drilling machine to move horizontally to adjust the drilling position. Before moving horizontally, the rotating frame adjusts the translation direction along the ring rail to adjust the drilling range. Then, the screw is rotated to drive the ring rail and the drilling machine to move up and down to perform drilling.

[0020] S3. When the clamping block rebounds under pressure, the pressing pin moves synchronously and pushes the ring frame to rotate along the bevel teeth. During this process, the magnetic block on the ring frame exerts magnetic traction along the connecting block on the outer ring of the end cover, causing the end cover to rotate along the inner support until the connecting block is horizontally inserted into the clamping slot;

[0021] S4. When the connecting block of the end cover enters the slot, the connecting block pushes up the pin along the first oblique side so that the pin is inserted into the hole on the surface of the connecting block. At this time, the end cover cannot rotate along the slot. After the punching is completed, the control ring is used to control the block to retract into the slide slot, and the pin is pushed up along the second oblique side, so that the card plate and the connecting block are unlocked.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] In the present invention, the card block is squeezed into the slide groove by the end cover along the oblique mouth until the end cover falls on the inner support. At this time, the card block is reset and pops out to be stuck on the upper side of the end cover, cooperating with the inner support to limit the up and down movement of the end cover, and when the card block pops out, the card plate at its bottom is synchronously pressed against the side of the end cover to limit the translation of the end cover. Compared with the existing horizontal clamping structure, the above-mentioned card block can automatically buckle when the end cover is pressed down by utilizing the oblique mouth, and can simultaneously realize the dual functions of clamping and centering the end cover in conjunction with the card plate, and the operation is simpler, reducing the difficulty of manual operation.

[0024] In the present invention, the ring frame is pushed to rotate along the bevel teeth by the pressing pin. During this process, the magnetic block on the ring frame exerts magnetic traction along the connecting block of the outer ring of the end cover, so that the end cover rotates along the inner support until the connecting block is horizontally inserted into the card slot. In this way, during the process of fixing the end cover, the movement of the card block is used to realize automatic adjustment of the position of the end cover, so that after the end cover is installed, a uniform punching effect can be ensured without manual adjustment, thereby reducing manual assistance and improving punching efficiency.

[0025] In the present invention, the connecting block pushes up the latch along the first oblique side so that the latch is inserted into the hole on the surface of the connecting block. At this time, the end cover cannot rotate along the card slot. After the drilling is completed, the control ring is used to control the card block to retract into the slide slot, and the latch is pushed up along the second oblique side, so that the card plate and the connecting block are unlocked. In this way, the latch realizes the dual functions of locking and quickly unlocking the end cover, and with the increase in functions, it will not make the disassembly and assembly of the end cover more complicated.

When the card block 6 pops out, the card plate 9 at the bottom thereof is synchronously pressed against the side of the end cover to limit the translation of the end cover. A pressing pin 10 is fixedly connected to the bottom of the card plate 9. When the card block 6 rebounds under pressure, the pressing pin 10 moves synchronously. A pin groove that cooperates with the pressing pin 10 is opened in the slide groove 5.

The drilling machine 2 is fixedly installed on the slide 25. When the screw rod 22 rotates, it drives the ring rail 23 and the drilling machine 2 to move up and down to perform drilling. The slide 25 moves along the rotating frame 24 to drive the drilling machine 2 to translate to adjust the drilling position. Before the translation, the rotating frame 24 is adjusted in the translation direction along the ring rail 23 to increase the drilling range.

[0046] A method for using a robot micro motor end cap punching device comprises the following steps:

[0047] S1. Place the end cap of the robot micro motor to be processed into the ring seat 3 and press it down. The end cap squeezes the clamping block 6 along the oblique opening 8 and retracts into the slide groove 5 until the end cap falls on the inner support 4. At this time, the clamping block 6 resets and pops out to be stuck on the upper side of the end cap, cooperating with the inner support 4 to limit the up and down movement of the end cap. When the clamping block 6 pops out, the clamping plate 9 at its bottom is simultaneously pressed against the side of the end cap to limit the translation of the end cap.

[0048] S2. After the end cover is completed, the slide 25 moves along the rotating frame 24 to drive the drilling machine 2 to translate and adjust the drilling position. Before the translation, the rotating frame 24 is adjusted along the ring rail 23 in the translation direction to adjust the drilling range. Then, the screw rod 22 is rotated to drive the ring rail 23 and the drilling machine 2 to move up and down to perform drilling.

[0049] S3, when the clamping block 6 rebounds under pressure, the pressing pin 10 moves synchronously and pushes the ring frame 12 to rotate along the bevel teeth 13. During this process, the magnetic block 14 on the ring frame 12 exerts magnetic traction along the connecting block of the outer ring of the end cover, causing the end cover to rotate along the inner support 4 until the connecting block is horizontally inserted into the clamping slot 15;

[0050] S4. When the connecting block of the end cover enters the slot 15, the connecting block pushes up the pin 18 along the first oblique edge 19, so that the pin 18 is inserted into the hole on the surface of the connecting block. At this time, the end cover cannot rotate along the slot 15. After the punching is completed, the control ring 27 is used to control the block 6 to retract into the slide groove 5, and the pin 18 is pushed up along the second oblique edge 20, so that the clamping plate 9 and the connecting block are unlocked.
