[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0028] Combination Figures 1-6 A main frame structure for a digital electrode cap grinding machine that can be quickly disassembled includes a support 1, a base 2, a power distribution box 5, and a grinding device 6. Two fixing frames 7 are fixedly mounted on the support 1. Mounting frames 8 are installed on both the power distribution box 5 and the grinding device 6. A mounting seat 3 is fixedly mounted on the base 2. The mounting seat 3 has a mounting groove 31 that is inserted into the support 1. A limiting plate 32 is fixedly installed in the mounting groove 31. A limiting groove 33 that is slidably connected to the limiting plate 32 is opened at the bottom of the support 1. Four self-locking casters 4 are installed at the bottom of the base 2. A support frame 9 for supporting the chip collection cylinder in the grinding device 6 is fixedly mounted on the support 1. A disassembly and assembly mechanism 10 is provided between the fixing frames 7 and the mounting frames 8.

[0029] See Figures 3-5Furthermore, the disassembly and assembly mechanism 10 includes a rod 102 fixedly mounted on the mounting bracket 8, a locking hole 103 on the rod 102, a slot 104 on the mounting bracket 7 for insertion into the rod 102, a slot 105 in the slot 104, a telescopic cavity 106, a winding cavity 107, and a transmission cavity 108 within the mounting bracket 7. A first slider 109 is slidably mounted within the telescopic cavity 106, a locking rod 1010 is fixedly connected to one side of the first slider 109, and a first spring 1011 is mounted on the other side of the first slider 109. The first spring 1011 is positioned between the first slider 109 and the telescopic cavity 106. The locking rod 1010 slides through the telescopic cavity 106 and passes through the locking hole 103, engaging with the slot 105. A rotating rod 1012 is rotatably mounted within the winding cavity 107. A take-up reel 1013 is fixedly sleeved on the rod 1012. A connecting rope 1014 is wound around the take-up reel 1013. The free end of the connecting rope 1014 passes through the take-up cavity 107 and extends into the telescopic cavity 106 to connect with the first slider 109. A worm gear 1015 is rotatably installed in the transmission cavity 108. The worm gear 1015 rotatably passes through the transmission cavity 108 and extends into the take-up cavity 107. A bevel gear transmission assembly 1016 is installed between the worm gear 1012 and the rotating rod 1012. A rotating rod 1017 is rotatably installed in the transmission cavity 108. A worm wheel 1018 that meshes with the worm gear 1015 is fixedly sleeved on the rotating rod 1017. One end of the rotating rod 1017 rotatably passes through the transmission cavity 108 and is fixedly connected to a rotating plate 1019. A locking assembly for locking the rotating rod 1017 is provided on the rotating plate 1019.

[0030] Specifically, by unlocking the rotating rod 1017 through the locking assembly, the locking rod 1010 disengages from the slot 105 and the lock hole 103 and retracts into the telescopic cavity 106. Then, the insertion rod 102 is slid out from the slot 104, thus completing the disassembly of the distribution box 5. Similarly, after disassembling the grinding device 6 by performing the above operations, the bracket 1 is removed from the mounting base 3, thus completing the quick disassembly of the device. The operation is simple, convenient, and time-saving, effectively meeting the high-frequency maintenance needs of the device.

[0031] See Figure 4Furthermore, the locking assembly on the rotating plate 1019 includes a sleeve 1020 fixedly mounted on the rotating plate 1019, a second slider 1021 slidably mounted inside the sleeve 1020, a first positioning hole 1026 and a second positioning hole 1027 opened on the side of the fixing frame 7 near the rotating plate 1019, a positioning rod 1022 adapted to the first positioning hole 1026 and the second positioning hole 1027 fixedly connected to one side of the second slider 1021, a guide rod 1023 fixedly connected to the other side of the second slider 1021, a second spring 1024 mounted on the guide rod 1023 between the sleeve 1020 and the second slider 1021, the guide rod 1023 slidably passes through the sleeve 1020 and is fixedly connected to a pull handle 1025.

[0032] Specifically, by pulling the handle 1025 outward, the guide rod 1023 drives the positioning rod 1022 to disengage from the first positioning hole 1026 via the second slider 1021. At this time, the second spring 1024 is compressed by the second slider 1021. Then, the sleeve 1020 is rotated to the second positioning hole 1027, and the handle 1025 is released. Under the rebound action of the second spring 1024, the positioning rod 1022 automatically engages in the second positioning hole 1027, thereby achieving the restriction and locking of the worm gear 1015 and preventing the locking rod 1010 from rebounding and affecting the installation and disassembly of the mounting bracket 8. This improves the convenience of the installation and disassembly operation of the mounting bracket 8.

[0033] In actual operation, by inserting the bottom of the bracket 1 into the mounting groove 31 on the mounting base 3 and sliding the limiting groove 33 downward along the direction of the limiting plate 32, the bracket 1 is fastened to the mounting base 3. Then, the self-locking universal wheel 4 at the bottom of the base 2 is used to move the bracket 1 to the designated position and lock it.

[0034] During installation of the distribution box 5 and the grinding device 6, by pulling the handle 1025 outward, the guide rod 1023, through the second slider 1021, causes the positioning rod 1022 to disengage from the first positioning hole 1026. At this time, the second spring 1024 is compressed by the second slider 1021. Then, by rotating the sleeve 1020, the rotating plate 1019 drives the rotating rod 1017 to rotate, causing the worm gear 1018 to drive the worm 1015 meshing with it to rotate. In the bevel gear transmission group... Under the transmission action of component 1016, the rotating rod 1012 drives the winding wheel 1013 to rotate. When the winding wheel 1013 rotates, it winds up the connecting rope 1014, causing the first slider 109 to be pulled and causing the locking rod 1010 to retract into the telescopic cavity 106 and squeeze the first spring 1011. At this time, the pull handle 1025 is released, and the positioning rod 1022 automatically engages in the second positioning hole 1027 under the rebound action of the second spring 1024, thus realizing the restriction of the locking rod 1010. After locking, align the mounting bracket 8 on the distribution box 5 with the lower fixing bracket 7, and insert the plug rod 102 into the slot 104. When the mounting bracket 8 and the fixing bracket 7 are in contact, pull the handle 1025 again to disengage the positioning rod 1022 from the second positioning hole 1027. Then, rotate the sleeve 1020 in the opposite direction to the first positioning hole 1026. During this process, the winding wheel 1013 gradually loosens the connecting rope 1014, thereby causing the locking rod 1010 to be released by the rebound of the first spring 1011. The device automatically passes through the lock hole 103 and engages in the slot 105. At this time, the pull handle 1025 is released to allow the positioning rod 1022 to engage in the first positioning hole 1026, thereby locking the locking rod 1010. This achieves the locking and fixing of the mounting bracket 8 and the lower fixing bracket 7, thus completing the installation of the distribution box 5. Similarly, the installation of the grinding device 6 can be performed by connecting it to the upper fixing bracket 7 according to the installation operation of the distribution box 5. The bearing bracket 9 is used to support the chip collection cylinder in the grinding device 6.

[0035] When disassembling the device, pull the handle 1025 outward to disengage the positioning rod 1022 from the first positioning hole 1026, rotate the sleeve 1020 to the second positioning hole 1027, and then release the handle 1025 to allow the positioning rod 1022 to engage in the first positioning hole 1026. At this time, the locking rod 1010 disengages from the slot 105 and the locking hole 103 and retracts into the telescopic cavity 106. Then, slide the insertion rod 102 out of the slot 104 to complete the disassembly of the distribution box 5. Similarly, after disassembling the grinding device 6 using the above operations, remove the bracket 1 from the mounting base 3 to complete the quick disassembly of the device.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
