Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to Figures 1-6 , the present invention provides a technical solution: a device for grinding the corners of carbon fiber pipes used in the production of bicycle brackets, including a working plate 1 and a motor 7. A vertical plate 2 is fixedly installed on the right side of the upper surface of the working plate 1, and a column 3 is fixedly installed on the left side of the upper surface of the working plate 1. Threaded rods 5 are provided inside the vertical plate 2 and the column 3, and limiting holes 4 are provided on the surfaces of the vertical plate 2 and the column 3;

[0034] The motor 7 is fixedly installed on the left side surface of the column 3, the output end of the motor 7 is threadedly connected to the grinding disc 8, and a pulley 10 is sleeved and connected to the surface of the motor 7;

[0035] A device for grinding the corners of carbon fiber pipes used in the production of bicycle brackets further includes:

[0036] A locking component, which is arranged below the threaded rod 5. Under the action of the threaded rod 5, the locking component can move up and down inside the vertical plate 2 and the column 3, and can clamp and fix the workpiece, facilitating the work of the grinding disc 8;

[0037] A material receiving component, which is arranged on the left side of the column 3. Under the action of thrust and elasticity, the material receiving component slides inside the column 3, which can not only receive materials but also quickly collect materials. The limiting column 17 is fixedly installed on the surface of the column 3, a cross bar 13 is fixedly installed on the inner wall of the column 3, and a connecting shaft 9 is rotatably arranged on the surface of the column 3.

[0038] Embodiment 1: As Figure 1 and Figure 2 shown in the technical solution, the present invention provides a technical solution: a device for grinding the corners of carbon fiber pipes used in the production of bicycle brackets, discloses:

[0039] The locking component includes a pressing block 6 fixedly installed on the lower surface of the threaded rod 5, and both sides of the lower surface of the pressing block 6 are inclined. The side view of the limiting hole 4 is an inverted triangular structure.

[0040] During operation, the carbon fiber tube is inserted from the vertical plate 2 and extends out from inside the column 3. At this time, the threaded rods 5 on both the left and right sides are rotated, causing the threaded rods 5 to drive the pressing block 6 to descend. Finally, the pressing blocks 6 on both the left and right sides clamp and fix the workpiece. The operation process is simple and fast. The cooperation between the pressing block 6 and the limiting hole 4 with an inverted triangular structure can better clamp and fix the workpiece, improving stability.

[0041] Embodiment 2. In this embodiment, different from Embodiment 1, by the operation of the motor 7, the receiving plate 11 is driven to move, which can better receive materials. As Figure 4 and Figure 5 shown, the other side of the pulley 10 is sleeved and connected to the surface of the connecting shaft 9, and a connecting gear 16 is fixedly installed on the surface of the connecting shaft 9. And the connecting gear 16 is a semi-gear structure. A long pin 19 is sleeved and connected to the surface of the limiting post 17.

[0042] Equidistantly fixed on the surface of the long pin 19 are tooth blocks 20 corresponding to the connecting gear 16, and a push plate 18 is fixedly installed on the lower surface of the long pin 19. The receiving component includes a limiting block 14 sleeved and connected to the surface of the cross bar 13. The lower surface of the push plate 18 is an inclined structure.

[0043] After the workpiece is clamped and fixed, the motor 7 is started. The motor 7 drives the grinding disc 8 to work to complete the grinding of the workpiece. At this time, the excess debris will fall on the receiving plate 11. At the same time, the motor 7 drives the connecting shaft 9 to rotate on the surface of the column 3 through the pulley 10. When the connecting shaft 9 rotates, the long pin 19 is driven to descend through the connecting gear 16 and the tooth block 20 (the limiting post 17 enables the long pin 19 to only move in the vertical direction). When the long pin 19 descends, the limiting block 14 is pushed by the push plate 18. At this time, the limiting block 14 will compress the connecting spring 15 (the cross bar 13 enables the limiting block 14 to only move in the horizontal direction). When the connecting gear 16 with a semi-gear structure is not engaged with the tooth block 20, the limiting block 14 moves back under the action of the connecting spring 15. Repeating the above process, the limiting block 14 drives the receiving plate 11 and the fixing plate 12 to perform a reciprocating linear motion in the horizontal direction. At this time, the receiving plate 11 can well collect and concentrate the materials, facilitating the collection by the staff and improving work efficiency.

[0044] Embodiment 3. In this embodiment, different from Embodiment 2, it is possible to avoid the scattering of debris during work. As Figure 4As shown, a fixing plate 12 is fixedly installed at the end of the limit block 14, and a material receiving plate 11 is fixedly installed on the surface of the fixing plate 12. Moreover, the upper surface of the material receiving plate 11 is inclined. A connecting spring 15 that plays an elastic reset role is fixedly installed on the surface of the limit block 14, and the other side of the connecting spring 15 is fixedly connected to the inner wall of the column 3.

[0045] During the collection process, the fixing plate 12 can prevent the scattered materials from spilling, facilitating the operation of the staff.

[0046] The above is the working process of the entire device, and the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0047] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
