Description

Technical Field

[0001] This application relates to the field of stamping grinding, and in particular to a stamping grinding device. Background Technology

[0002] Automobiles typically use a large number of stamped parts. After being formed, these parts usually need to be ground to meet the corresponding process standards.

[0003] For grinding stamped parts, a double-sided grinding machine is typically used. A double-sided grinding machine generally includes a housing, an upper grinding disc, a lower grinding disc, a drive mechanism, and a spindle. The lower grinding disc, drive mechanism, and spindle are all mounted on the housing. The lower grinding disc is rotatably mounted on the spindle, and both the spindle and the lower grinding disc are connected to the drive mechanism. The drive mechanism drives the spindle and the lower grinding disc to rotate, with the lower grinding disc rotating in the opposite direction to the spindle. The upper grinding disc is mounted above the housing via a lifting mechanism and can be inserted into the spindle, rotating coaxially with it. By placing the workpiece on the lower grinding disc and then lowering the upper grinding disc via the lifting mechanism, the upper grinding disc comes into contact with the workpiece, thus pressing the workpiece firmly between the upper and lower grinding discs. The drive mechanism then drives the spindle and the lower grinding disc to rotate, and the spindle in turn drives the upper grinding disc to rotate, thereby achieving double-sided grinding of the workpiece.

[0004] Currently, after a period of use, the upper and lower grinding discs are prone to wear, resulting in a deterioration in the grinding effect. This necessitates the disassembly and replacement of the upper and lower grinding discs. However, both the upper and lower grinding discs are fixed to the lifting mechanism and the machine housing with bolts, making disassembly and replacement inconvenient. Summary of the Invention

[0005] In order to facilitate the disassembly and replacement of the upper and lower grinding discs, this application provides a grinding device for stamped parts.

[0006] This application provides a grinding equipment for stamped parts, which adopts the following technical solution:

[0007] A stamping part grinding equipment includes a chassis, on which a grinding device is mounted. The grinding device includes a drive mechanism, an upper grinding mechanism, and a lower grinding mechanism. The drive mechanism is mounted on the chassis and connected to the upper and lower grinding mechanisms. The upper grinding mechanism includes an upper grinding disc, which is mounted on the chassis via an upper quick-release mechanism. The lower grinding mechanism includes a lower grinding disc, which is mounted on the chassis via a detachable mechanism and is located below the upper grinding disc. A space for placing a workpiece is provided between the upper and lower grinding discs.

[0008] By adopting the above technical solution, the upper grinding disc in the upper grinding mechanism and the lower grinding disc in the lower grinding mechanism are driven by the drive mechanism to grind the stamped parts placed on the lower grinding disc. When the upper and lower grinding discs are worn and need to be replaced, the upper grinding disc is removed from the upper grinding mechanism through the quick-release mechanism, and a new upper grinding disc is installed in the upper grinding mechanism through the quick-release mechanism. The lower grinding disc is removed from the chassis through the detachable mechanism, and a new lower grinding disc is installed on the chassis through the detachable mechanism, thus facilitating the disassembly and replacement of the upper and lower grinding discs.

[0009] In one specific implementation, the upper grinding mechanism further includes a lifting assembly, which includes a lifting frame and a lifting cylinder. The lifting frame is mounted on the chassis, and the lifting cylinder is mounted on the lifting frame. The piston rod of the lifting cylinder extends downward, and a mounting bracket is mounted on the piston rod of the lifting cylinder. The upper grinding disc is mounted on the mounting bracket via a quick-release mechanism, and the mounting bracket is connected to the drive mechanism.

[0010] By adopting the above technical solution, the mounting bracket is driven to descend by the lifting cylinder, thereby connecting the mounting bracket to the drive mechanism. This allows the drive mechanism to drive the mounting bracket to rotate, which in turn drives the upper grinding disc to rotate. The mounting bracket then causes the upper grinding disc to press against the stamped part located on the lower grinding disc, thus facilitating the grinding of the top wall of the stamped part when the upper grinding disc rotates.

[0011] In one specific implementation, the quick-release mechanism includes a detachment component, a locking component, and a linkage component. The locking component includes a locking pin and a locking spring. A locking post is installed on the top wall of the upper grinding disc, and a locking hole is provided on the side wall of the locking post. The mounting bracket has a mounting hole for the locking post to be inserted into. The locking pin is installed on the top wall of the mounting bracket and is inserted into the locking hole. The locking spring is installed on the mounting bracket, with one end connected to the mounting bracket and the other end connected to the locking pin. The linkage component is installed on the mounting bracket and is connected to the locking pin. The detachment component is installed on the mounting bracket and is connected to the linkage component. The detachment component is also connected to the upper grinding disc.

[0012] By adopting the above technical solution, the locking pin is driven to slide and compress the locking spring through the linkage component, thereby separating the locking pin from the locking hole on the locking post, thus unlocking the locking post and facilitating the disassembly of the upper grinding disc.

[0013] In one specific implementation scheme, the linkage assembly includes a linkage ring, a linkage rod, and a positioning element. The linkage ring is rotatably mounted on the top wall of the mounting frame, and the linkage rod is rotatably mounted on the top wall of the mounting frame. One end of the linkage rod is connected to the linkage ring, and the other end is connected to one end of a locking pin. A sliding rod is mounted on the linkage ring, and a sliding groove for the sliding rod to slide is provided on the top wall of the mounting frame. The positioning element is mounted on the mounting frame and is connected to the sliding rod.

[0014] By adopting the above technical solution, the linkage ring is driven to rotate by the slide rod, which in turn drives the linkage rod to rotate, thereby causing the linkage rod to slide the locking pin, thus unlocking the locking pin from the locking post, which facilitates the unloading of the upper grinding disc.

[0015] In one specific implementation, the positioning element includes a positioning block and a guide block. The positioning block is installed at one end of the slide rod located in the slide groove, and the guide block is installed on the inner wall of the slide groove and located above the positioning block. The guide block is used to limit the positioning block, and the detachment component is connected to the positioning block.

[0016] By adopting the above technical solution, during the sliding process of the slide bar, the guide block limits the positioning block, so that the positioning block is connected to the detachment component, thereby driving the detachment component to move, so that the detachment component pushes the upper grinding disc out of the mounting frame, thus facilitating the unloading of the upper grinding disc.

[0017] In one specific implementation, the detachment assembly includes a detachment rod, a pressure block, and a detachment spring. The pressure block is installed in a groove and is located below a guide block. The pressure block has a guide ramp that extends downward from one end of the pressure block to its lower end and is used to abut against a positioning block. The detachment rod is installed on the bottom wall of the pressure block, with one end extending downward and the lower end of the detachment rod abutting against an upper grinding disc. The detachment spring is installed on the detachment rod, with one end connected to the side wall of the detachment rod and the other end connected to the bottom wall of the pressure block.

[0018] By adopting the above technical solution, when the locking pin and the locking post are separated, the positioning block on the slide rod slides along the guide slope of the pressure block to the top wall of the pressure block, thereby pushing the pressure block downward, so that the pressure block drives the release rod to contact the upper grinding disc, thereby pushing the release rod out of the mounting bracket, thus realizing the disassembly of the upper grinding disc.

[0019] In one specific implementation, a guide cylinder is installed on the bottom wall of the pressure block, the detachment rod is slidably installed in the guide cylinder in the vertical direction, and one end of the detachment rod extends downward out of the guide cylinder. A limiting plate for limiting the detachment spring is installed on the side wall of the detachment rod outside the guide cylinder. The limiting plate is located in the slide groove, and the detachment spring is located between the pressure block and the limiting plate.

[0020] By adopting the above technical solution, when installing a new upper grinding disc, the locking pin of the upper grinding disc is inserted into the mounting hole, and the locking hole is aligned with the locking pin. When the upper grinding disc abuts against the release rod and pushes the release rod upward, the limiting plate compresses the release spring, so that the release rod is buffered in the guide tube, thereby facilitating the installation of the upper grinding disc.

[0021] In one specific implementation, the lower grinding mechanism further includes a rotating platform. A baffle is installed on the chassis. The rotating platform is rotatably mounted on the chassis and is located inside the baffle. The rotating platform is connected to the drive mechanism. A positioning post is installed on the bottom wall of the lower grinding disc. A limiting hole for the positioning post to be inserted is opened on the rotating platform. A positioning hole is opened on the side wall of the positioning post. The positioning post is installed on the rotating platform through a detachable mechanism.

[0022] By adopting the above technical solution, the positioning pin on the lower grinding disc is inserted into the limiting hole on the rotating platform so that the detachable mechanism can lock the lower grinding disc, and the rotating platform is driven to rotate by the drive mechanism, thereby driving the lower grinding disc to rotate, so as to grind the stamped parts.

[0023] In one specific implementation, the detachable mechanism includes a disassembly assembly comprising a disassembly ring, a disassembly spring, and a disassembly rod. An installation groove is provided within the rotating platform near the limiting hole. The disassembly rod is slidably installed within the installation groove, with one end extending outward from the side wall of the rotating platform. The disassembly ring is installed within a retaining cover, and its side wall abuts against the end of the disassembly rod located outside the rotating platform. A push rod is installed on the side wall of the disassembly ring, passing through the side wall of the retaining cover and extending outward. A return spring is installed on the push rod, with one end abutting against the side wall of the disassembly ring and the other end connected to the inner wall of the retaining cover. A disassembly block is installed on the side wall of the disassembly rod located within the installation groove. The disassembly block is trapezoidal, with its hypotenuse abutting against the side wall of the positioning hole. The disassembly spring is installed within the installation groove, with one end abutting against the side wall of the disassembly block and the other end abutting against the inner wall of the installation groove.

[0024] By adopting the above technical solution, when it is necessary to disassemble the lower grinding disc, by pressing the push rod, the reset spring is stretched, and the push rod pushes the disassembly ring toward the rotating platform, thereby causing the disassembly ring to push the disassembly rod, which in turn causes the disassembly block to move away from the positioning post and compress the disassembly spring, thereby separating the disassembly block from the positioning post and unlocking the positioning post, so as to facilitate the disassembly of the lower grinding disc.

[0025] In one specific implementation, the detachable mechanism further includes a lifting assembly, which includes a lifting rod and a lifting spring. The rotating platform is also provided with a lifting groove. The lifting rod is slidably installed in the lifting groove in a vertical direction. A baffle is installed on the side wall of the lifting rod. The lifting spring is installed on the lifting rod, and one end of the lifting spring abuts against the top wall of the baffle, while the other end abuts against the inner top wall of the lifting groove. The lower end of the lifting rod is provided with a lifting ramp, which is located below the baffle and is used to abut against the end of the detachable rod.

[0026] By adopting the above technical solution, after the disassembly block separates from the positioning column, as the disassembly rod continues to move, the disassembly rod abuts against the lifting slope of the lifting rod, thereby lifting the lifting rod upward and compressing the lifting spring, so that the lifting rod lifts the lower grinding disc, thus facilitating the unloading of the lower grinding disc.

[0027] In summary, this application includes at least one of the following beneficial effects:

[0028] 1. This application provides a quick-release mechanism to facilitate the disassembly and installation of the upper grinding disc.

[0029] 2. This application provides a detachable mechanism to facilitate the disassembly and installation of the lower grinding disc.

[0030] 3. This application, by setting up a detachment component and a lifting component, facilitates the automatic detachment of the upper grinding plate by driving it downward through the detachment component after the upper grinding plate is unlocked from the locking component; and facilitates the automatic lifting of the lower grinding plate by lifting the lower grinding plate after the lower grinding plate is unlocked from the disassembly component, so as to facilitate the replacement of the upper and lower grinding plates.

Detailed Implementation

[0041] The present application will be further described in detail below with reference to the accompanying drawings.

[0042] This application discloses a stamping parts grinding equipment, referring to... Figure 1The device includes a chassis 1, on which a grinding device is mounted. The grinding device includes an upper grinding mechanism 2, a lower grinding mechanism 3, and a drive mechanism. The lower grinding mechanism 3 is mounted on the chassis 1, and the upper grinding mechanism 2 is mounted on the chassis 1 and located above the lower grinding mechanism 3. The drive mechanism is mounted on the chassis 1 (not shown in the figure) and is used to drive the upper grinding mechanism 2 and the lower grinding mechanism 3 to operate. The drive mechanism is prior art in this field and will not be described in detail here.

[0043] Reference Figure 1 and Figure 2 The upper grinding mechanism 2 includes a lifting assembly 22 and an upper grinding disc 21. The lifting assembly 22 includes a lifting frame 221 and a lifting cylinder 222. The lifting frame 221 is fixedly installed on the housing 1, and the lifting cylinder 222 is fixedly installed on the lifting frame 221. The piston rod of the lifting cylinder 222 extends downward, and a mounting bracket 223 is rotatably mounted on the piston rod of the lifting cylinder 222. The upper grinding disc 21 is mounted on the bottom wall of the mounting bracket 223 through a quick-release mechanism 4. A docking hole is provided in the center of the mounting bracket 223 for connecting with the drive mechanism on the housing 1.

[0044] Reference Figure 2 and Figure 3 The quick-release mechanism 4 includes a locking assembly 41 and a linkage assembly 42. The locking assembly 41 includes a locking pin 411 and a locking spring 414. Several locking pins 211 are fixedly installed on the top wall of the upper grinding disc 21. The top wall of the mounting bracket 223 has mounting holes 2231 for the locking pins 211 to be inserted into, and the locking pins 211 pass through the mounting holes 2231 and extend upward. The top wall of the mounting bracket 223 has a deflection groove 2232 at the mounting hole 2231. The side wall of the portion of the locking pin 211 located in the deflection groove 2232 has a... A locking pin 411 is slidably installed in a deflection groove 2232, with a slotted hole 412 on its top wall. A limiting block 413 is fixedly installed in the deflection groove 2232 of the mounting bracket 223. The locking pin 411 is slidably connected to the limiting block 413 through the slotted hole 412, and the length of the slotted hole 412 is greater than the length of the limiting block 413. The axis of the locking pin 411 is perpendicular to the axis of the locking post 211, and one end of the locking pin 411 is inserted into the locking hole 212, while the other end is connected to the linkage assembly 42. A locking spring 414 is installed in the deflection groove 2232, with one end of the locking spring 414 abutting against the side wall of the deflection groove 2232 and the other end abutting against the end of the locking pin 411 away from the locking post 211.

[0045] Reference Figure 3 and Figure 4The linkage assembly 42 includes a linkage ring 421, a linkage rod 422, and a positioning element. The linkage ring 421 is rotatably mounted on the top wall of the mounting bracket 223 at the docking hole, and the rotation axis of the linkage ring 421 is the axis of the docking hole. The linkage rod 422 is rotatably mounted in the deflection groove 2232 on the top wall of the mounting bracket 223. One end of the linkage rod 422 is slidably connected to the end of the locking pin 411 away from the locking post 211, and the other end is slidably connected to the linkage ring 421. The connection parts of the linkage rod 422 with the locking pin 411 and the linkage ring 421 are all provided with waist-shaped holes.

[0046] Reference Figure 2 and Figure 5 A sliding rod 423 is fixedly installed vertically on the top wall of the linkage ring 421. A sliding groove 2233 is formed on the top wall of the mounting bracket 223 along the rotation direction of the linkage ring 421. The lower end of the sliding rod 423 extends downward into the sliding groove 2233. The positioning component includes a positioning block 424 and a guide block 425. The positioning block 424 is fixedly installed at one end of the sliding rod 423 located in the sliding groove 2233. The positioning block 424 has a circular cross-section, and its diameter is larger than that of the sliding rod 423. Two guide blocks 425 are provided and are fixedly installed on the side walls on both sides of the sliding groove 2233. The gap between the two guide blocks 425 allows the sliding rod 423 to slide, and both guide blocks 425 are located above the positioning block 424.

[0047] Reference Figure 5 The quick-release mechanism 4 also includes a detachment assembly 43, which includes a detachment rod 431, a pressure block 432, and a detachment spring 435. The pressure block 432 is slidably installed in the slide groove 2233 in the vertical direction, and is located below the positioning block 424 and the guide block 425. A guide slope 4321 is provided at the upper end of the pressure block 432. One end of the guide slope 4321 extends downward from the top wall of one end of the pressure block 432 to the other end, and the guide slope 4321 on the pressure block 432 is used to abut against the bottom wall of the positioning block 424. A guide cylinder 433 is fixedly installed on the bottom wall of the pressure block 432. One end of the detachment rod 431 is slidably installed in the guide cylinder 433, and the other end extends downward, and the lower end of the detachment rod 431 is used to abut against the top wall of the upper grinding disc 21. A limiting plate 434 is fixedly installed on the side wall of the detachment rod 431. A detachment spring 435 is installed on the detachment rod 431 and is located between the limiting plate 434 and the guide cylinder 433. One end of the detachment spring 435 abuts against the top wall of the limiting plate 434 and the other end abuts against the lower end of the guide cylinder 433.

[0048] Reference Figure 3 and Figure 5When the grinding disc 21 needs to be replaced, the slide bar 423 is moved, which causes the linkage ring 421 to rotate. This causes the linkage ring 421 to rotate the linkage rod 422, which in turn causes the linkage rod 422 to pull the locking pin 411 from the locking post 211 away from the locking post 211. This causes the locking pin 411 to separate from the locking post 211 and compress the locking spring 414, thereby releasing the locking pin 411 from the grinding disc 21. While the sliding rod 423 drives the linkage ring 421 to rotate, the sliding rod 423 drives the positioning block 424 to slide in the sliding groove 2233, so that the positioning block 424 slides along the bottom wall of the guide block 425 and slides along the guide inclined surface 4321 of the pressure block 432 to the top wall of the pressure block 432, thereby pushing the pressure block 432 to move downward. When the locking pin 411 is in the positioning state of the locking post 211, the guide cylinder 433 compresses the release spring 435 downward. When the locking pin 411 separates from the locking post 211, the release spring 435 returns to the relaxed state, thereby pushing the limit plate 434 to move downward, thereby driving the release rod 431 to move downward, so that the release rod 431 pushes the upper grinding plate 21 downward, thereby separating the upper grinding plate 21 from the mounting bracket 223.

[0049] Reference Figure 6 and Figure 7 The lower grinding mechanism 3 includes a lower grinding disc 31 and a rotating platform 32. A baffle 11 is fixedly installed on the top wall of the housing 1. The rotating platform 32 is rotatably installed on the housing 1 and is located inside the baffle 11. A drive shaft 33 is rotatably installed at the axis of the rotating platform 32. Both the rotating platform 32 and the drive shaft 33 are connected to the drive mechanism. The drive shaft 33 is also connected to the mounting bracket 223. The lower grinding disc 31 is installed on the rotating platform 32 through a detachable mechanism 5.

[0050] Reference Figure 7 and Figure 8The detachable mechanism 5 includes a detachment component 51 and a lifting component 52. The detachment component 51 includes a detachment ring 511, a detachment spring 513 and a detachment rod 514. A positioning post 311 is fixedly installed on the bottom wall of the lower grinding disc 31 in the vertical direction. A positioning hole 312 is opened on the side wall of the positioning post 311. A limiting hole 322 for the positioning post 311 to be inserted is opened on the top wall of the rotating platform 32. An installation groove is provided inside the rotating platform 32 near the limiting hole 322. The axis of the installation groove is perpendicular to the axis of the limiting hole 322. The disassembly rod 514 is slidably installed in the installation groove on the rotating platform 32 in the horizontal direction, and one end of the disassembly rod 514 extends outward from the peripheral side wall of the rotating platform 32. A disassembly block 515 is fixedly installed on the side wall of the disassembly rod 514 inside the rotating platform 32. The disassembly block 515 is used to insert into the positioning hole 312 on the positioning post 311. The cross-section of the disassembly block 515 is a right trapezoid, and the hypotenuse of the right trapezoidal disassembly block 515 is used to abut against the side wall at the upper end of the positioning hole 312 on the positioning post 311. The disassembly spring 513 is installed in the installation groove, and one end of the disassembly spring 513 abuts against the inner wall of the installation groove, and the other end abuts against the end of the disassembly block 515 away from the positioning post 311.

[0051] Reference Figure 6 and Figure 8 The disassembly ring 511 is slidably mounted on the side wall of the housing 1 near the rotating platform 32. The side wall of the disassembly ring 511 is used to abut against the end of the disassembly rod 514 located outside the rotating platform 32. A push rod 512 is fixedly mounted on the side wall of the disassembly ring 511 away from the rotating platform 32. The push rod 512 passes through the side wall of the baffle 11 and extends outward. A return spring 516 is also mounted on the push rod 512. One end of the return spring 516 is fixedly connected to the side wall of the disassembly ring 511, and the other end is fixedly connected to the inner wall of the baffle 11.

[0052] Reference Figure 7 and Figure 8 The lifting assembly 52 includes a lifting rod 521 and a lifting spring 523. A lifting groove 321 is provided on the top wall of the rotating platform 32. The lifting rod 521 is slidably installed in the lifting groove 321 in the vertical direction. The upper end of the lifting rod 521 is used to abut against the bottom wall of the lower grinding disc 31. The lower end of the lifting rod 521 is provided with a lifting inclined surface 5211. One end of the lifting inclined surface 5211 extends upward from the bottom wall of the lifting rod 521 towards the direction of the disassembly rod 514 to the side wall of the lifting rod 521. The lifting inclined surface 5211 at the lower end of the lifting rod 521 is used to abut against the end of the disassembly rod 514. A baffle 522 is also fixedly installed on the side wall of the lifting rod 521. The baffle 522 is located above the lifting inclined surface 5211. The lifting spring 523 is installed on the lifting rod 521, and one end of the lifting spring 523 abuts against the top wall of the baffle 522, while the other end abuts against the inner top wall of the lifting groove 321.

[0053] Reference Figure 7 and Figure 8 When it is necessary to disassemble the lower grinding disc 31, by pushing the push rod 512, the push rod 512 causes the disassembly ring 511 to abut against the disassembly rod 514, thereby pushing the disassembly rod 514 away from the disassembly ring 511. This causes the disassembly rod 514 to move the disassembly block 515 away from the positioning post 311 and compress the disassembly spring 513, thereby separating the disassembly block 515 from the positioning hole 312 on the positioning post 311 and releasing the lock on the positioning post 311. Then, as the disassembly rod 514 continues to move, the end of the disassembly rod 514 away from the disassembly ring 511 abuts against the lifting slope 5211 of the lifting rod 521, thereby pushing the lifting rod 521 upward and compressing the lifting spring 523, thereby lifting the lower grinding disc 31, which facilitates the disassembly of the lower grinding disc.

[0054] Reference Figure 7 and Figure 8 When the lower grinding disc 31 needs to be installed, the positioning pin 311 on the lower grinding disc 31 is aligned with the limiting hole 322 on the rotating platform 32, and the positioning pin 311 is inserted into the limiting hole 322. This causes the lower end of the positioning pin 311 to abut against the inclined surface of the disassembly block 515, which has a trapezoidal cross-section. This pushes the disassembly block 515 away from the positioning pin 311 and compresses the disassembly spring 513. When the positioning pin 311 is in place, the end of the disassembly block 515 slides along the side wall of the positioning pin 311 to the positioning hole 312. At this time, the end of the disassembly rod 514 near the lifting rod 521 remains separated from the lifting rod 521, and the disassembly block 515 is reset under the action of the disassembly spring 513, thereby inserting the disassembly block 515 into the positioning hole 312 and positioning the positioning pin 311.

[0055] The working principle of this embodiment is as follows: The stamped part is placed on the lower grinding disc 31. The lifting cylinder 222 drives the mounting bracket 223 to descend, thereby connecting the mating hole on the mounting bracket 223 with the drive shaft 33. The mounting bracket 223 rotates coaxially with the drive shaft 33, causing the upper grinding disc 21 to press the stamped part on the lower grinding disc 31. Then, the drive mechanism drives the drive shaft 33 to rotate, thereby causing the drive shaft 33 to rotate and the mounting bracket 223 to rotate, which in turn drives the upper grinding disc 21 to rotate, thus grinding the upper surface of the stamped part on the lower grinding disc 31. At the same time, the drive mechanism drives the rotating platform 32 to rotate a full number of revolutions, thereby causing the lower grinding disc 31 to rotate, thus grinding the lower surface of the stamped part on the lower grinding disc 31.

[0056] When the upper grinding disc 21 and the lower grinding disc 31 have finished grinding a certain batch of stamped parts, and it is necessary to replace the upper grinding disc 21 and the lower grinding disc 31 with new ones, or to replace the upper grinding disc 21 and the lower grinding disc 31 with different models, the linkage ring 421 is rotated clockwise by the slide rod 423, so that the linkage ring 421 drives the linkage rod 422 to rotate, so that the linkage rod 422 pulls the locking pin 411 to slide away from the locking post 211, so that the locking pin 411 separates from the locking post 211 and compresses the locking spring 414, thereby releasing the lock on the locking post 211. When the locking pin 411 separates from the locking post 211, the positioning block 424 slides in the groove 2233 to the guide slope 4321 on the pressure block 432, and slides along the guide slope 4321 to the top wall of the pressure block 432, thereby pressing the pressure block 432 downward, which causes the pressure block 432 to drive the release rod 431 to move downward, thereby pushing the release rod 431 downward on the upper grinding disc 21, thereby separating the upper grinding disc 21 from the mounting bracket 223, so as to facilitate the disassembly of the upper grinding disc 21.

[0057] When replacing the upper grinding disc 21, the locking pin 211 on the upper grinding disc 21 is inserted into the mounting hole 2231, causing the top wall of the upper grinding disc 21 to abut against the release rod 431 and push the release rod 431 upward. This causes the release rod 431 to compress the release spring 435 through the limiting plate 434, so that the locking hole 212 on the locking pin 211 of the upper grinding disc 21 can be aligned with the locking pin 411. Then, the linkage ring 421 is rotated counterclockwise by the slide rod 423, causing the linkage ring 421 to drive the linkage rod 422 to rotate. This causes the linkage rod 422 to drive the locking pin 411 to slide towards the locking pin 211, and the locking pin 411 is inserted into the locking hole 212 under the action of the locking spring 414. This achieves the positioning and installation of the upper grinding disc 21. At this time, the locking spring 414 keeps the locking pin 411 stably inserted into the locking hole 212.

[0058] When disassembling the old lower grinding disc 31, the push rod 512 is pushed, causing the push rod 512 to drive the disassembly ring 511 to push the disassembly rod 514. This causes the disassembly rod 514 to drive the disassembly block 515 to compress the disassembly spring 513, and causes the disassembly block 515 to separate from the positioning hole 312 on the positioning post 311, thereby releasing the positioning of the positioning post 311. Then, as the disassembly rod 514 is further pushed towards the lifting rod 521, and the end of the disassembly rod 514 abuts against the lifting inclined surface 5211 on the lifting rod 521, the lifting rod 521 is lifted upward and the lifting spring 523 is compressed. This causes the lifting rod 521 to lift the lower grinding disc 31 upward, thereby facilitating the unloading of the lower grinding disc. After the lower grinding disc 31 is removed, the push rod 512 is released, causing the disassembly ring 511 to reset under the action of the reset spring 516, the disassembly rod 514 to reset under the action of the disassembly spring 513, and the lifting rod 521 to reset under the action of the lifting spring 523.

[0059] When replacing the lower grinding disc 31, the positioning pin 311 on the lower grinding disc 31 is inserted into the limiting hole 322, so that the end of the positioning pin 311 abuts against the inclined surface of the disassembly block 515, and the disassembly block 515 is pushed towards the disassembly spring 513, thereby compressing the disassembly spring 513. When the positioning pin 311 continues to move downward until the end of the disassembly block 515 slides along the side wall of the positioning pin 311 to the positioning hole 312, the disassembly block 515 is reset under the action of the disassembly spring 513, so that the disassembly block 515 is inserted into the positioning hole 312, thereby positioning the positioning pin 311, and thus realizing the installation of the lower grinding disc 31.

[0060] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be included within the scope of protection of this application.
