Description

Technical Field

[0001] This utility model relates to the field of polishing wheel technology, specifically a polishing wheel that is easy to disassemble. Background Technology

[0002] Polishing wheels are used for polishing workpiece surfaces and coatings. Polishing wheels are frequently used in metal processing.

[0003] The utility model patent application with publication number "CN222177251 U" discloses a polishing wheel that is easy to disassemble. It mainly consists of a base, a motor, a rotating shaft, and a support block. This technical solution facilitates quick disassembly and assembly of the polishing wheel, ensures stable installation, and provides a convenient and easy-to-use polishing wheel.

[0004] The aforementioned document discloses a polishing wheel that is easy to disassemble, which has the following defects: This technical solution drives the threaded rod to rotate by rotating the rotating block, and uses the threaded pair transmission to make the push plate move axially. The push plate and the snap plate are engaged on the inclined surface to convert the axial displacement into radial locking motion, so that the snap plate is embedded in the snap groove of the polishing wheel, realizing a rigid connection between the support block and the polishing wheel. However, during long-term use, the threaded meshing surface of the threaded rod and the push plate is continuously subjected to alternating stress, which is prone to progressive wear, resulting in a decrease in axial preload. When the threaded pair clearance increases to a critical value, the push plate cannot provide sufficient radial locking stroke, causing the snap plate to fall out of the snap groove, ultimately causing the polishing wheel locking function to fail. Utility Model Content

[0005] The purpose of this invention is to provide a polishing wheel that is easy to disassemble, thereby solving the problem that existing easy-to-disassemble polishing wheels do not have a good locking effect.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a polishing wheel that is easy to disassemble, comprising a motor and a polishing wheel. The output end of the motor is provided with an output shaft. The polishing wheel is mounted on the outer surface of the output shaft via a connecting assembly. The connecting assembly includes a first connecting plate, which is mounted on the outer surface of the output shaft. One end of the first connecting plate is provided with a connecting block, and one end of the connecting block is provided with a second connecting plate. The polishing wheel is mounted on the outer surface of the connecting block. The outer surface of the second connecting plate has a first groove, and the inner surface of the first groove has a slanted sliding groove. The inner surface of the slanted sliding groove has a limiting hole. One end of the limiting hole passes through the connecting block and the second connecting plate sequentially and extends outward. A turntable is rotatably connected inside the first groove. The outer surface of the turntable has a mounting hole, and the inner surface of the mounting hole is provided with a first spring. One end of the first spring is provided with a limiting rod, and one end of the limiting rod is fitted inside the limiting hole.

[0008] Furthermore, a cover plate is installed on the outer surface of the second connecting plate, and a mounting hole is formed on the outer surface of the cover plate. A knob is rotatably connected inside the mounting hole, and one end of the knob is installed on the outer surface of the turntable.

[0009] Furthermore, a sealing block is provided on the outer surface of the second connecting plate, and one end of the sealing block is interference-fitted into the inside of the limiting hole.

[0010] Furthermore, the outer surface of the output shaft is provided with a mounting groove, the outer surface of the first connecting plate is provided with a second groove, and the inner surface of the second groove is provided with a second spring.

[0011] Furthermore, a slider is installed at one end of the second spring, the slider is slidably connected inside the second groove, a limit block is installed at one end of the slider, and one end of the limit block passes through the first connecting plate and is fitted inside the mounting groove.

[0012] Furthermore, both ends of the polishing wheel are provided with pads, one of which abuts against the outer surface of the first connecting disk at one end, and the other of the pad abuts against the outer surface of the second connecting disk at the other end.

[0013] This utility model has the following beneficial effects:

[0014] (1) By rotating the knob, the drive turntable rotates in the first groove. Under the guidance of the inclined slide, the limiting rod moves radially along a predetermined trajectory. During this process, the first spring continuously releases stored energy, pushing the limiting rod to slide into the depth of the inclined slide. When the knob is rotated to the set angle, the axis of the limiting rod is completely aligned with the limiting hole. The restoring force of the first spring instantly ejects the limiting rod into the depth of the limiting hole, forming a rigid mechanical interlock between the connecting block and the second connecting plate, ensuring that the polishing wheel maintains good locking when subjected to high-speed rotational load.

[0015] (2) In this utility model, the shaft hole of the first connecting plate is aligned with the end of the output shaft and pushed in. At this time, the limiting block is squeezed back into the second groove by the outer wall of the output shaft. When the first connecting plate is pushed to the preset position, the mounting groove and the limiting block are automatically aligned. The second spring releases its stored energy instantly, driving the limiting block to be ejected and embedded deep into the mounting groove, thus completing the mechanical interlock between the first connecting plate and the output shaft and achieving the effect of quick installation.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0027] Please see Figures 1-6As shown, this utility model is a polishing wheel that is easy to disassemble, including a motor 1 and a polishing wheel 2. The output end of the motor 1 is provided with an output shaft 101. The polishing wheel 2 is mounted on the outer surface of the output shaft 101 through a connecting assembly 3. The connecting assembly 3 includes a first connecting plate 301, which is mounted on the outer surface of the output shaft 101. One end of the first connecting plate 301 is provided with a connecting block 302, and one end of the connecting block 302 is mounted with a second connecting plate 303. The polishing wheel 2 is mounted on the outer surface of the connecting block 302, and the outer surface of the second connecting plate 303 is... The surface is provided with a first groove 304, the inner surface of the first groove 304 is provided with an inclined sliding groove, the inner surface of the inclined sliding groove is provided with a limiting hole 305, one end of the limiting hole 305 passes through the connecting block 302 and the second connecting plate 303 in sequence and extends outward, the inside of the first groove 304 is rotatably connected to a turntable 306, the outer surface of the turntable 306 is provided with a mounting hole, the inner surface of the mounting hole is provided with a first spring 307, one end of the first spring 307 is provided with a limiting rod 308, and one end of the limiting rod 308 is fitted inside the limiting hole 305;

[0028] A cover plate 309 is installed on the outer surface of the second connecting plate 303. An installation hole is opened on the outer surface of the cover plate 309. A knob 3010 is rotatably connected inside the installation hole. One end of the knob 3010 is installed on the outer surface of the turntable 306.

[0029] By rotating the knob 3010, the turntable 306 is driven to rotate within the first groove 304. Under the guidance of the inclined slide, the limiting rod 308 moves radially along a predetermined trajectory. During this process, the first spring 307 continuously releases stored energy, pushing the limiting rod 308 to slide deeper into the inclined slide. When the knob 3010 is rotated to the set angle, the axis of the limiting rod 308 is completely aligned with the limiting hole 305. The restoring force of the first spring 307 instantly ejects the limiting rod 308 into the depth of the limiting hole 305, forming a rigid mechanical interlock between the connecting block 302 and the second connecting disc 303, ensuring that the polishing wheel 2 maintains good locking when subjected to high-speed rotational load.

[0030] A sealing block 3011 is provided on the outer surface of the second connecting plate 303, and one end of the sealing block 3011 is interference-fitted into the inside of the limiting hole 305.

[0031] The outer surface of the output shaft 101 is provided with a mounting groove 102, the outer surface of the first connecting plate 301 is provided with a second groove 3012, and the inner surface of the second groove 3012 is provided with a second spring 3013.

[0032] A slider 3014 is installed at one end of the second spring 3013. The slider 3014 is slidably connected to the inside of the second groove 3012. A limit block 3015 is installed at one end of the slider 3014. One end of the limit block 3015 passes through the first connecting plate 301 and is fitted inside the mounting groove 102.

[0033] During installation, the shaft hole of the first connecting plate 301 is aligned with the end of the output shaft 101 and pushed in. At this time, the limiting block 3015 is squeezed back into the second groove 3012 by the outer wall of the output shaft 101. When the first connecting plate 301 is pushed to the preset position, the mounting groove 102 and the limiting block 3015 are automatically aligned. The second spring 3013 releases its stored energy instantly, driving the limiting block 3015 to be ejected and embedded deep into the mounting groove 102, thus completing the mechanical interlock between the first connecting plate 301 and the output shaft 101 and achieving the effect of quick installation.

[0034] Both ends of the polishing wheel 2 are provided with a pad 3016. One end of the pad 3016 abuts against the outer surface of the first connecting plate 301, and the other end of the pad 3016 abuts against the outer surface of the second connecting plate 303.

[0035] In use, firstly, align the shaft hole of the first connecting plate 301 with the end of the output shaft 101 and push it in. At this time, the limiting block 3015 is squeezed back into the second groove 3012 by the outer wall of the output shaft 101. When the first connecting plate 301 is pushed to the preset position, the mounting groove 102 and the limiting block 3015 automatically align. The second spring 3013 instantly releases its stored energy, driving the limiting block 3015 to be ejected and embedded deep into the mounting groove 102, completing the mechanical interlock between the first connecting plate 301 and the output shaft 101. Then, install the double gaskets 3016 and the polishing wheel 2 in sequence, so that the gaskets 3016 are tightly attached to the end faces of the first connecting plate 301 and the polishing wheel 2 respectively to form a vibration buffer layer. Finally, take out the second connecting plate 303 and install the second connecting plate 303 on the outer surface of the connecting block 302. The limiting hole 305 of the second connecting plate 303 is aligned with the limiting hole 305 of the connecting block 302. By rotating the knob 3010, the turntable 306 is driven to rotate in the first groove 304. The limiting rod 308 moves radially along a predetermined trajectory under the guidance of the inclined slide. During this process, the first spring 307 continuously releases stored energy, pushing the limiting rod 308 to slide deeper into the inclined slide. When the knob 3010 is rotated to the set angle, the axis of the limiting rod 308 is completely aligned with the limiting hole 305. The restoring force of the first spring 307 instantly ejects the limiting rod 308 into the depth of the limiting hole 305, forming a rigid mechanical interlock between the connecting block 302 and the second connecting plate 303, ensuring that the polishing wheel 2 maintains good locking when subjected to high-speed rotational load.

[0036] When the polishing wheel needs to be replaced, first remove the sealing block 3011 to expose the limiting hole 305, insert the ejector pin into the limiting hole 305 to press against the end of the limiting rod 308 and apply pressure to overcome the resistance of the first spring 307, pushing the limiting rod 308 completely out of the limiting hole 305 of the connecting block 302 to the inclined slide plane. At this time, rotate the knob 3010 to drive the turntable 306 to rotate in the opposite direction, and the inclined slide guides the limiting rod 308 to retract radially. After the knob 3010 rotates 90°, the second connecting plate 303 and the polishing wheel 2 can be pulled outward, so that the polishing wheel 2 is disengaged from the output shaft 101, achieving the effect of easy disassembly.
