Description

Technical Field

[0001] This utility model belongs to the field of diamond industrial brushes, and specifically relates to a concave curved surface diamond industrial brush. Background Technology

[0002] In the diamond processing process, the surface of the diamond needs to be ground to make it smoother and flatter. A grinding brush is a tool mainly used for diamond processing. It is made by firmly fixing the bristles on a brush plate. The bristles on existing diamond grinding brushes are generally arranged relatively densely on the brush plate. During use, the bristles often cannot maintain their original hardness for a long time. After a period of use, the bristles are prone to spreading out, resulting in poor grinding effect and a short service life of the grinding brush.

[0003] Chinese Patent No. CN215547956U discloses a concave curved diamond brush, including a curved brush disc. The inner side of the curved brush disc has arc-shaped slots arranged in a circular array, and arc-shaped locking blocks are movably engaged with the inner walls of multiple arc-shaped slots. This concave curved diamond brush features a quick-change device on the outer side of the curved brush disc, including fixing blocks. The lower surfaces of multiple fixing blocks are fixedly connected to the outer side of the curved brush disc, facilitating grinding of curved workpieces and easy replacement of damaged bristles. This addresses the problem that most existing diamond brushes are end-face brushes, suitable for flat workpieces, but have low grinding efficiency when grinding curved workpieces. Furthermore, when some bristles are damaged, the entire brush disc needs to be replaced, resulting in significant waste, and continued use can lead to poor grinding quality.

[0004] As can be seen from the above structure, by setting a quick-change device on the outer side of the curved brush disk, and the quick-change device includes a fixing block, the lower surface of which is fixedly connected to the outer side of the curved brush disk, it is easy to grind curved workpieces and easy to replace the damaged brush bristles. However, the arc angle of the diamond industrial brush cannot be adjusted during use, which results in an ineffective cleaning effect when facing different curved materials, thus reducing the practicality of the device. Therefore, an adjustable concave curved diamond industrial brush is proposed. Utility Model Content

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A concave curved diamond industrial brush includes a frame, a mounting plate fixedly connected to the upper end of the frame, an adjusting component provided at the lower end of the mounting plate, snap-fit ​​components fixedly connected to the periphery of the frame, a brush rod fixedly connected to the outer side of the frame via the snap-fit ​​components, and brushes provided on the inner side of the brush rod. The adjusting component includes an adjusting screw rotatably connected to the lower end of the mounting plate, an adjusting sleeve threadedly connected to the outer surface of the adjusting screw, a four-sided rack fixedly connected to the lower end of the adjusting sleeve, transmission gears rotatably connected to the periphery of the frame, the four-sided rack meshing with the transmission gears, an adjusting gear fixedly connected to the outer side of the snap-fit ​​components, the adjusting gear meshing with the transmission gears, and a handle fixedly connected to the other end of the adjusting screw through the mounting plate.

[0008] As a preferred technical solution, the snap-fit ​​assembly includes snap-fit ​​plates disposed on the periphery of the frame. Snap-fit ​​holes are formed on the surface of each snap-fit ​​plate. One end of the brush rod is fixedly connected to a snap-fit ​​block, which is inserted into the inner side of the snap-fit ​​plate. Circular grooves are formed on both sides of the snap-fit ​​block, and snap-fit ​​springs are fixedly connected inside each groove. A snap-fit ​​connector is fixedly connected to the other end of each snap-fit ​​spring, and the snap-fit ​​connector engages with the snap-fit ​​holes. The other end of the snap-fit ​​block is fixedly connected to an adjusting gear.

[0009] As a preferred technical solution, the outer side of the snap-fit ​​plate is fixedly connected to a support rod, the inner side of the support rod is provided with a release groove, the inside of the release groove is fixedly connected to a release spring, the other end of the release spring is fixedly connected to a connecting plate, the inner side of the connecting plate is fixedly connected to a release block, and the release block is inserted into the snap-fit ​​hole.

[0010] As a preferred technical solution, the lower end of the quadrangular rack is slidably inserted into the lower end of the frame, a limiting groove is provided at the lower end of the quadrangular rack, and a limiting rod is fixedly connected to the lower end of the frame, with the limiting rod and the limiting groove slidably inserted into each other.

[0011] As a preferred technical solution, a protective plate is rotatably connected to the bottom of the frame, a rotating column is fixedly connected to the upper end of the protective plate, and a rotating groove is opened at the lower end of the frame, with the rotating groove and the rotating column rotatably connected to each other.

[0012] As a preferred technical solution, the upper end of the brush rod is provided with a mounting hole, a mounting screw is inserted into the inside of the mounting hole, and a mounting screw hole is provided on the outer side of the snap-fit ​​block. The mounting screw passes through the mounting hole and is threadedly connected to the mounting screw hole.

[0013] As a preferred technical solution, a connecting rod is fixedly connected to the upper end of the frame, and a fixing plate is fixedly connected to the upper end of the connecting rod. A fixing hole is opened on the surface of the fixing plate, and a fixing screw is inserted into the fixing hole.

[0014] In summary, the present invention has the following main advantages:

[0015] First, this utility model, through its adjustable component, allows for adjustment of the concave angle of the brush rod. Rotating the handle causes the adjusting screw to rotate, which in turn causes the adjusting sleeve to move on the surface of the adjusting screw under the action of the thread. This movement of the adjusting sleeve drives the four-sided rack to move, which in turn drives the transmission gear to rotate. The rotation of the transmission gear drives the adjusting gear to rotate, which in turn drives the locking block to rotate, thereby rotating the brush rod. This allows for adjustment of the brush rod angle. When the four-sided rack moves upward, the brush rod angle increases, and vice versa, thus increasing the practicality of the device.

[0016] Secondly, this utility model, through its snap-fit ​​assembly, allows for easy installation of the brush rod. When the snap-fit ​​block is inserted into the snap-fit ​​plate, the snap-fit ​​connector is compressed into the circular groove. After the snap-fit ​​block is fully inserted into the snap-fit ​​frame, the snap-fit ​​hole aligns with the circular groove. At this point, the snap-fit ​​connector pops out of the groove under the action of the snap-fit ​​spring, engaging with the snap-fit ​​hole to achieve the snap-fit ​​effect. This facilitates the installation of the brush rod. Conversely, during disassembly, pressing the connecting plate causes the release spring to contract, moving the release block downwards and engaging with the snap-fit ​​hole. This allows the snap-fit ​​connector to be squeezed out of the snap-fit ​​hole, making the brush rod easy to disassemble. Attached Figure Description

Both sides of the snap-fit ​​block 43 have circular grooves 44, and snap-fit ​​springs 45 are fixedly connected inside each groove 44. The other end of each snap-fit ​​spring 45 is fixedly connected to a snap-fit ​​connector 46, which snaps into the snap-fit ​​holes 42. The other end of the snap-fit ​​block 43 is connected to an adjusting gear. 35 are fixedly connected to each other; by inserting the snap-fit ​​block 43 into the inside of the snap-fit ​​plate 41, the snap-fit ​​connector 46 is squeezed into the inside of the circular groove 44 during insertion. Then, after the snap-fit ​​block 43 is completely inserted into the inside of the snap-fit ​​frame, the position of the snap-fit ​​hole 42 is consistent with the position of the circular groove 44. At this time, the snap-fit ​​connector 46 will pop out of the circular groove 44 under the action of the snap-fit ​​spring 45, so that the snap-fit ​​connector 46 and the snap-fit ​​hole 42 can be snapped together, thereby achieving the snap-fit ​​effect and enabling the brush rod 5 to be installed.

[0026] refer to Figure 4 The outer side of the snap-fit ​​plate 41 is fixedly connected to the support rod 18, and the inner side of the support rod 18 is provided with the release groove 19.

[0030] Operating principle and advantages: First, the brush is installed on the surface of the brush rod 5. Then, the snap-fit ​​block 43 is inserted into the snap-fit ​​plate 41. During insertion, the snap-fit ​​connector 46 is squeezed into the circular groove 44. After the snap-fit ​​block 43 is fully inserted into the snap-fit ​​frame, the position of the snap-fit ​​hole 42 is aligned with the position of the circular groove 44. At this time, the snap-fit ​​connector 46 will pop out of the circular groove 44 under the action of the snap-fit ​​spring 45, so that the snap-fit ​​connector 46 and the snap-fit ​​hole 42 are snapped together, thus achieving the snap-fit ​​effect and enabling the installation of the brush rod 5. Then, by rotating the handle 36, the adjusting screw 31 is rotated, and the adjustment... The rotation of the adjusting screw 31 causes the adjusting sleeve 32 to move on the surface of the adjusting screw 31 under the action of the thread principle. This movement of the adjusting sleeve 32 drives the four-sided rack 33 to move, which in turn drives the transmission gear 34 to rotate. The rotation of the transmission gear 34 drives the adjusting gear 35 to rotate, which in turn drives the locking block 43 to rotate, thereby driving the brush rod 5 to rotate. This allows the angle of the brush rod 5 to be adjusted. After the angle is adjusted, the fixed plate 7 and the fixed screw are used to install it with the drive device, so that the device can be used normally.
