Description

Technical Field

[0001] This utility model relates to the field of flange cleaning technology for aluminum alloy wheel hubs, specifically a brush disc with easily replaceable bristles. Background Technology

[0002] The flange of an aluminum alloy wheel hub specifically refers to the contact surface where the wheel hub and the vehicle's brake disc are installed. It is the core load-bearing and positioning component in the wheel hub structure, and a brush disc is required when cleaning it.

[0003] However, due to the characteristics of the product, the existing brush discs require the use of special soft bristles to ensure that they will not scratch the flange when cleaning it. As a result, the bristles have a short lifespan and need to be replaced frequently. However, since the bristles and the brush disc are an integral part of each other, the long replacement cycle affects production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a brush disc with easily replaceable bristles, in order to solve the problem mentioned in the background art that the bristles and the brush disc are an integral whole.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a brush disc with easily replaceable bristles, comprising:

[0006] A brush disc is provided with brush bristles at its lower part. A limit block is embedded in the upper surface of the brush bristles. Ordinary springs are provided inside both sides of the brush disc. One end of each ordinary spring is connected to a protrusion. The lower surface of the brush bristles abuts against a limit plate. A rotating ring is fixedly installed above the limit plate. A limit ring is connected to the inner side of the rotating ring. A torsion spring is connected above the rotating ring. A fixing ring is connected above the torsion spring. A protective ring is installed on the outer side of the fixing ring.

[0007] Preferably, the brush disk is fixedly connected to the limiting blocks, and four limiting blocks are provided and evenly distributed below the brush disk.

[0008] Preferably, the bristles have grooves on both sides corresponding to the size of the limiting plate.

[0009] Preferably, the two ends of the ordinary spring are fixedly connected to the brush plate and the protrusion, respectively, and the protrusion is slidably connected to the brush plate.

[0010] Preferably, the rotating ring and the limiting ring are rotatably connected, and the limiting ring and the brush plate are fixedly connected.

[0011] Preferably, the two ends of the torsion spring are fixedly connected to the rotating ring and the fixed ring, respectively, and the fixed ring is fixedly connected to the brush plate.

[0012] Preferably, the protective ring is fixedly connected to the fixed ring, and the lower part of the protective ring abuts against the outer surface of the rotating ring.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] When the brush disc of this utility model needs to be replaced, the brush disc can be stabilized, the protrusion is pressed into the brush disc, and the rotating ring is rotated around the limiting ring. The rotating ring drives the limiting plate to rotate, so that the limiting plate passes the protrusion. The protrusion and the rotating ring are released, and under the elastic force of the ordinary spring, the protrusion moves out of the brush disc. Under the elastic force of the torsion spring, the rotating ring rotates back and abuts against the outside of the protrusion. At this time, the limiting plate is aligned with the groove of the brush bristles, and the brush bristles can be taken out from under the brush disc for replacement. Only the brush bristles need to be replaced, and the brush disc, as a consumable, can continue to be reused. This strengthens cost rational management, shortens the replacement cycle with each replacement, and allows for the replacement of different bristle materials according to different products. It can accurately solve quality problems and improve production efficiency. The quick and convenient replacement method can greatly reduce downtime and reduce cost waste. Attached Figure Description

[0021] 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.

[0022] Please see Figure 1-5One embodiment of this utility model is a brush disc with easily replaceable bristles.

[0023] The device includes: a brush plate 01, with brush bristles 02 located below the brush plate 01. A limit block 03 is embedded inside the upper surface of the brush bristles 02, limiting the movement of the brush bristles 02 and preventing them from rotating. Ordinary springs 04 are installed inside both sides of the brush plate 01, providing elastic force. Under the elastic force of the ordinary springs 04, protrusions 05 move out of the brush plate 01. One end of the ordinary spring 04 is connected to the protrusions 05, which guide the brush plate 01. The protrusions 05 can abut against a rotating ring 07, preventing the ring 07 from rotating back. The lower surface of the brush bristles 02 abuts against a limit plate 06, which is aligned with the grooves of the brush bristles 02. The bristles 02 can be removed from under the brush plate 01 for replacement. A rotating ring 07 is fixedly installed above the limiting plate 06. The rotating ring 07 drives the limiting plate 06 to rotate, so that the limiting plate 06 passes the protrusion 05. A limiting ring 08 is connected to the inner side of the rotating ring 07. A torsion spring 09 is connected above the rotating ring 07. The torsion spring 09 provides elastic force. Under the action of the elastic force of the torsion spring 09, the rotating ring 07 can rotate around the limiting ring 08 and return to the initial position. A fixing ring 10 is connected above the torsion spring 09. A protective ring 11 is installed on the outer side of the fixing ring 10. The protective ring 11 can protect the torsion spring 09 and prevent water stains from contaminating the torsion spring 09.

[0024] Furthermore, the brush plate 01 is fixedly connected to the limiting block 03 to ensure the stability of the position of the limiting block 03. There are four limiting blocks 03, which are evenly distributed below the brush plate 01. The limiting blocks 03 play a role in limiting the brush bristles 02 and preventing the brush bristles 02 from rotating.

[0025] Furthermore, the bristles 02 have grooves on both sides corresponding to the size of the limiting plate 06. The limiting plate 06 is aligned with the grooves of the bristles 02, so that the bristles 02 can be removed from under the brush plate 01 for replacement.

[0026] Furthermore, the two ends of the ordinary spring 04 are fixedly connected to the brush plate 01 and the protrusion 05 respectively. The ordinary spring 04 provides elastic force. Under the action of the elastic force of the ordinary spring 04, the protrusion 05 moves out of the brush plate 01. The protrusion 05 is slidably connected to the brush plate 01. The brush plate 01 plays a guiding role for the protrusion 05. The protrusion 05 can resist the rotating ring 07 and prevent the rotating ring 07 from rotating back.

[0027] Furthermore, the rotating ring 07 and the limiting ring 08 are rotatably connected. The rotating ring 07 drives the limiting plate 06 to rotate, so that the limiting plate 06 passes through the protrusion 05. The limiting ring 08 is fixedly connected to the brush plate 01 to ensure the stability of the position of the limiting ring 08.

[0028] Furthermore, the two ends of the torsion spring 09 are fixedly connected to the rotating ring 07 and the fixed ring 10 respectively. The torsion spring 09 provides elastic force, which allows the rotating ring 07 to rotate around the limiting ring 08 and return to the initial position. The fixed ring 10 is fixedly connected to the brush plate 01 to ensure the stability of the fixed ring 10 position.

[0029] Furthermore, the protective ring 11 is fixedly connected to the fixed ring 10 to ensure the stability of the positions of the fixed ring 10 and the protective ring 11. The lower part of the protective ring 11 abuts against the outer surface of the rotating ring 07. The protective ring 11 can protect the torsion spring 09 and prevent water stains from contaminating the torsion spring 09.

[0030] Working principle: First, stabilize the brush plate 01. Press the protrusion 05 into the brush plate 01. Rotate the rotating ring 07 around the limiting ring 08. The rotating ring 07 drives the limiting plate 06 to rotate, allowing the limiting plate 06 to pass the protrusion 05. Release the protrusion 05 and the rotating ring 07. Under the elastic force of the ordinary spring 04, the protrusion 05 moves out of the brush plate 01. Under the elastic force of the torsion spring 09, the rotating ring 07 rotates back and abuts against the outside of the protrusion 05. At this time, the limiting plate 06 aligns with the groove of the bristles 02, allowing the bristles 02 to be removed from under the brush plate 01 for replacement. The above is the complete working principle of this utility model.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
