Description

Technical Field

[0001] This disclosure relates to the field of polishing equipment, and in particular to a quick adjustment mechanism for the polishing machine disc. Background Technology

[0002] In modern industrial production, polishing machines are an important type of surface treatment equipment. The working principle of a polishing machine usually involves the relative movement of an upper grinding disc and a lower grinding disc (or polishing pad). The workpiece is placed between the two grinding discs, and the surface is polished under the action of pressure and friction.

[0003] During polishing operations, different workpieces have different materials, shapes, sizes, and polishing requirements, so it is often necessary to change the upper grinding disc of different specifications or materials according to the specific situation. At the same time, in order to obtain the best polishing effect, it is sometimes necessary to precisely adjust the position of the upper grinding disc.

[0004] However, the upper grinding disc structure of most polishing machines is currently quite complex, making disassembly and assembly cumbersome and requiring the use of multiple tools, which consumes a significant amount of time and manpower. Furthermore, adjusting the position of the upper grinding disc is not convenient enough to meet the need for rapid adjustment according to production requirements.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] This disclosure provides a quick adjustment mechanism for the polishing machine grinding disc, which can solve the problem of how to improve the convenience of disassembling, replacing and adjusting the position of the upper grinding disc in the prior art.

[0008] (II) Technical Solution

[0009] To solve the above-mentioned technical problems, this disclosure provides the following technical solution:

[0010] A quick adjustment mechanism for a polishing machine grinding disc, the quick adjustment mechanism for a polishing machine grinding disc includes:

[0011] Base;

[0012] The mounting bracket assembly includes a bracket, a mounting base, and a first adjusting screw. The bracket is rotatably connected to the base via a rotating shaft. The mounting base is slidably disposed on the bracket and can slide along a first direction. The first adjusting screw is rotatably disposed on the bracket and extends along the first direction. The first adjusting screw is threadedly connected to the mounting base.

[0013] The quick-installation assembly includes an adjustment seat fixedly disposed on the mounting base, a second adjustment screw threadedly connected to the adjustment seat, and a first locking bolt. The adjustment seat is provided with a mounting hole extending in a second direction. A mounting rod is slidably disposed in the mounting hole. The mounting rod is used to install a grinding disc. The first locking bolt is used to fix the mounting rod. The bottom of the second adjustment screw is rotatably supported on the base so that the bracket rotates around the pivot when the second adjustment screw rotates.

[0014] Wherein, the first direction is perpendicular to the second direction.

[0015] In some embodiments, the mounting base assembly further includes a guide rod disposed on the bracket along a first direction, and the mounting base is provided with a guide hole and slidably disposed on the guide rod through the guide hole.

[0016] In some embodiments, the bracket is provided with a mounting cavity, the mounting seat is disposed in the mounting cavity, and portions of the guide rod and adjusting screw are disposed in the mounting cavity.

[0017] In some embodiments, the mounting bracket assembly further includes a locking screw that is threadedly connected to the bracket and used to lock the first adjusting screw.

[0018] In some embodiments, the adjusting seat is fixedly provided with a mounting plate, and the mounting plate is fixedly provided with a first positioning pin. The first positioning pin is fixedly provided with the main body of the mounting plate and the head fixedly provided with the end of the main body. The mounting seat is provided with a pin hole, and the pin hole is provided with a first hole position and a second hole position. The radius of the first hole position, the radius of the head, the radius of the second hole position, and the radius of the main body decrease sequentially, so that the first positioning pin can be inserted into the end of the first hole position away from the mounting plate and moved to the end of the second hole position away from the mounting plate, thereby snapping the mounting plate into the mounting seat.

[0019] In some embodiments, the quick-release assembly further includes a second positioning pin. The mounting base is provided with a positioning hole. The second positioning pin is axially movable in the adjusting base. When the first positioning pin moves to the end of the second hole away from the mounting plate, the second positioning pin can be separated and disposed in the positioning hole to restrict the mounting plate and the first positioning pin from moving towards the first hole and to fix the mounting plate.

[0020] In some embodiments, the mounting rod is provided with a locking hole parallel to the second adjusting screw, a lifting rod is provided in the locking hole, and the mounting rod is provided with a second locking bolt to fix the position of the lifting rod.

[0021] (III) Beneficial Effects

[0022] Compared with the prior art, the beneficial effects of the technical solution provided in this disclosure include at least the following:

[0023] The quick-adjustment mechanism for the polishing machine disc disclosed herein operates by inserting a mounting rod into the mounting hole of the adjusting seat, with the disc mounted on the rod. Once the mounting rod is in the appropriate position, tighten the first locking bolt. The first locking bolt abuts against the mounting rod, fixing it in place within the mounting hole, thus completing the installation of the disc. For disassembly, loosen the first locking bolt, pull out the mounting rod, and the disc can be removed, making disassembly and assembly convenient. When adjusting the disc position, rotating the first adjusting screw causes the mounting seat to slide along the first direction, allowing adjustment of the disc's position in that direction, as the first adjusting screw is threadedly connected to the mounting seat and extends in the first direction. Rotating the second adjusting screw, whose bottom is rotatably supported on the base and threadedly connected to the adjusting seat, causes the bracket to rotate around its axis, thereby rotating the mounting seat and disc around the axis, allowing angle adjustment of the disc in a plane perpendicular to the first direction. Simultaneously, controlling the depth to which the mounting rod is inserted into the mounting hole of the adjusting seat adjusts the disc's position in the second direction. As can be seen, the quick-adjustment mechanism for the polishing machine disc of this disclosure can quickly and accurately change the position and angle of the disc in the first direction by rotating the first and second adjusting screws, utilizing the principle of threaded transmission. By adjusting the position of the mounting rod in the second direction, the position of the disc in the second direction can be changed to meet different polishing needs. Furthermore, the quick-adjustment mechanism for the polishing machine disc of this disclosure only requires tightening or loosening the first locking bolt to install and remove the mounting rod and the disc, making operation simple and convenient, saving time and manpower.

[0039] The upper grinding disc structure of most existing polishing machines is relatively complex, and the disassembly and assembly process is cumbersome, requiring the use of multiple tools and consuming a lot of time and manpower. In addition, the operation of adjusting the position of the upper grinding disc is not convenient enough, making it difficult to meet the needs of quickly adjusting the grinding disc position according to production requirements.

[0040] To solve the above-mentioned technical problems, this embodiment provides a quick adjustment mechanism for the polishing machine grinding disc.

[0041] Figure 1 This is a perspective view of the rapid adjustment mechanism of the polishing machine disc in an embodiment of this disclosure. Figure 2 This is a perspective view of the mounting bracket assembly in an embodiment of this disclosure. Figure 3 This is a perspective view of the quick-installation component in an embodiment of this disclosure.

[0042] See Figures 1 to 3As shown, the quick adjustment mechanism for the polishing machine disc in this embodiment includes: a base 100, a mounting base assembly 200, and a quick-release assembly 300.

[0043] The base 100 can be mounted on the frame of the polishing machine.

[0044] The mounting bracket assembly 200 includes a bracket 210, a mounting base 220, and a first adjusting screw 230. The bracket 210 is rotatably connected to the base 100 via a rotating shaft 211. The mounting base 220 is slidably disposed on the bracket 210 and can slide along a first direction. The first adjusting screw 230 is rotatably disposed on the bracket 210 and extends along the first direction. The first adjusting screw 230 is threadedly connected to the mounting base 220.

[0045] The quick-install assembly 300 includes an adjustment seat 310 fixedly disposed on the mounting base 220, a second adjustment screw 320 threadedly connected to the adjustment seat 310, and a first locking bolt 330. The adjustment seat 310 is provided with a mounting hole 311 extending in a second direction. A mounting rod 340 is slidably disposed in the mounting hole 311. The mounting rod 340 is used to install the grinding disc 400. The first locking bolt 330 is used to abut against the mounting rod 340. The bottom of the second adjustment screw 320 is rotatably supported on the base 100 so that the bracket 210 rotates around the pivot 211 when the second adjustment screw 320 rotates.

[0046] The first direction is perpendicular to the second direction.

[0047] The first direction can be horizontal. Meanwhile, since the bracket 210 can rotate around the pivot 211, the second direction and the extension direction of the second adjusting screw 320 will change as the bracket 210 rotates. For example, when the bracket 210 rotates to a certain angle, the second direction is horizontal, while the second adjusting screw 320 extends vertically.

[0048] The mounting base assembly 200 also includes a guide rod 240, which is disposed on the bracket 210 along a first direction. The mounting base 220 is provided with a guide hole 221 and is slidably disposed on the guide rod 240 through the guide hole 221. The guide rod 240 and the slidable mounting base 220 on it through the guide hole 221 provide stable guidance for the sliding of the mounting base 220 along the first direction, ensuring the straightness and smoothness of the mounting base 220's movement, reducing wobbling and deviation during sliding, and making the position adjustment of the grinding disc 400 in the first direction more precise and reliable, thereby improving polishing accuracy and quality.

[0049] The bracket 210 is provided with a mounting cavity 212, the mounting base 220 is disposed in the mounting cavity 212, and the guide rod 240 and part of the first adjusting screw 230 are disposed in the mounting cavity 212. This arrangement makes the entire mounting base assembly 200 more compact, reduces space occupation, and facilitates the overall layout and installation of the polishing machine. At the same time, the mounting cavity 212 also provides a certain degree of protection for the mounting base 220, the guide rod 240, and the first adjusting screw 230, preventing damage from external factors.

[0050] The rotating shaft 211 extends into the mounting cavity 212, and the mounting base 220 is slidably set on the rotating shaft 211 through the guide hole 221. At this time, the rotating shaft 211 serves as both the rotation hub of the bracket 210 and the guide structure of the mounting base 220. That is, one component achieves two functions, saving parts and improving rigidity.

[0051] The mounting bracket assembly 200 also includes a locking screw 250, which is threaded to the bracket 210 and used to lock the first adjusting screw 230. After the grinding disc 400 is adjusted to the position in the first direction, the locking screw 250 can be used to fix the first adjusting screw 230 to prevent it from rotating on its own due to vibration or other reasons, thereby ensuring the stability of the grinding disc 400 position and avoiding displacement of the grinding disc 400 position during the polishing process, which would affect the polishing effect.

[0052] The adjusting seat 310 is fixedly provided with a mounting plate 312, and the mounting plate 312 is fixedly provided with a first positioning pin 313. The first positioning pin 313 is fixedly provided with a main body 313A of the mounting plate 312 and a head 313B fixedly provided at the end of the main body 313A. The mounting seat 220 is provided with a pin hole 222, which is provided with a first hole 222A and a second hole 222B. The radius of the first hole 222A, the radius of the head 313B, the radius of the second hole 222B and the radius of the main body 313A decrease sequentially, so that the first positioning pin 313 can be inserted into the end of the first hole 222A away from the mounting plate 312 and moved to the end of the second hole 222B away from the mounting plate 312, thereby snapping the mounting plate 312 into the mounting seat 220. That is, the first positioning pin 313 can be inserted into the first hole 222A from the proximal end of the pin hole 222 (the end near the adjusting seat 310) and moved to the distal end. At the same time, the main body 313A enters the first hole 222A, pushing the mounting plate 312 to make the first positioning pin 313 move radially along the pin hole 222 until its head 313B moves to the distal outer side of the second hole 222B and abuts against the surface of the mounting seat 220. At the same time, the main body 313A enters the second hole 222B, thereby locking the mounting plate 312 to the mounting seat 220. With this configuration, the special cooperation between the first positioning pin 313 and the pin hole 222 enables the quick engagement of the mounting plate 312 and the mounting seat 220. This engagement method is simple and efficient, and the connection between the quick-installation component 300 and the mounting seat 220 can be completed without complicated operations, greatly improving the convenience and efficiency of the grinding disc 400 installation.

[0053] The quick-install assembly 300 also includes a second positioning pin 314. The mounting base 220 is provided with a positioning hole 223. The second positioning pin 314 is axially movable in the adjusting base 310. When the first positioning pin 313 moves to the end of the second hole 222B away from the mounting plate 312, the second positioning pin 314 is detachably positioned within the positioning hole 223 to restrict the movement of the mounting plate 312 and the first positioning pin 313 towards the first hole 222A, thus fixing the mounting plate 312. During operation, the second positioning pin 314 is first pulled out in the direction away from the positioning hole 223. When the first positioning pin 313 moves to the end of the second hole 222B away from the mounting plate 312, the second positioning pin 314 is then inserted back into the positioning hole 223. The second positioning pin 314 cooperates with the positioning hole 223 to further restrict the first positioning pin 313 from moving in the direction of the first hole 222A, prevent the first positioning pin 313 from disengaging from the pin hole 222, enhance the fixing effect on the mounting plate 312, ensure the firmness of the connection between the quick-release assembly 300 and the mounting base 220, prevent the quick-release assembly 300 from loosening during the polishing process, and ensure the normal operation of the grinding disc 400.

[0054] In some embodiments, the mounting rod 340 is provided with a locking hole 341 parallel to the second adjusting screw 320, and a lifting rod 342 is disposed within the locking hole 341. The mounting rod 340 is provided with a second locking bolt 343 for fixing the position of the lifting rod 342. By adjusting the height of the lifting rod 342, the installation requirements of grinding discs 400 of different sizes or shapes can be accommodated, improving the versatility of this quick adjustment mechanism.

[0055] In summary, when the quick adjustment mechanism for the polishing machine grinding disc in this embodiment is working, the mounting rod 340 is inserted into the mounting hole 311 of the adjusting seat 310, and the grinding disc 400 is mounted on the mounting rod 340. After the mounting rod 340 is inserted into the appropriate position, the first locking bolt 330 is tightened. The first locking bolt 330 abuts against the mounting rod 340, fixing it in the mounting hole 311, thus completing the installation of the grinding disc 400. For disassembly, the first locking bolt 330 is loosened, the mounting rod 340 is pulled out, and the grinding disc 400 can be removed, making disassembly and assembly convenient. When adjusting the position of the grinding disc 400, the first adjusting screw 230 is rotated. Since the first adjusting screw 230 is threadedly connected to the mounting seat 220 and extends along the first direction, the mounting seat 220 will slide along the first direction on the bracket 210, realizing the position adjustment of the grinding disc 400 in the first direction. Rotating the second adjusting screw 320, whose bottom is rotatably supported on the base 100 and threadedly connected to the adjusting seat 310, causes the bracket 210 to rotate around the rotating shaft 211, thereby driving the mounting seat 220 and the grinding disc 400 to rotate around the rotating shaft 211, realizing the angle adjustment of the grinding disc 400 in a plane perpendicular to the first direction. Simultaneously, controlling the insertion depth of the mounting rod 340 into the mounting hole 311 of the adjusting seat 310 adjusts the position of the grinding disc 400 in the second direction. It can be seen that the polishing machine grinding disc quick adjustment mechanism of this disclosure, by rotating the first adjusting screw 230 and the second adjusting screw 320, utilizes the threaded transmission principle to quickly and accurately change the position and angle of the grinding disc 400 in the first direction, and by adjusting the position of the mounting rod 340 in the second direction, changes the position of the grinding disc 400 in the second direction to meet different polishing needs. Meanwhile, the quick adjustment mechanism of the polishing machine grinding disc 400 disclosed herein can realize the installation and disassembly of the mounting rod 340 and the grinding disc 400 simply by tightening or loosening the first locking bolt 330. The operation is simple and convenient, saving time and manpower.
