Description

Milling tool for disc brake caliper mount Technical Field

[0001] This new type of tool is applied to the maintenance of bicycle caliper seats, especially a milling tool for disc brake caliper seats. Prior Technology

[0002] Note: With the increasing popularity of sports, many places have begun to plan dedicated bike lanes for public use. Besides physical exercise, cycling also promotes interpersonal communication, leading to a growing number of people choosing cycling as their form of exercise. Existing tools for adjusting bicycle disc brake caliper mounting brackets mostly involve mounting a guide shaft on the frame or fork and milling the paint on the mounting surface of the caliper bracket using a rotating cutting tool. However, this method relies on accuracy and even force application. Uneven force can easily cause the mounting surface of the caliper bracket to fail to maintain a proper perpendicular or parallel relationship with the disc's rotation surface, thus affecting the operation of the braking system. Furthermore, existing adjustment tools require specific tools for different disc brake calipers, making assembly cumbersome and affecting repair efficiency. Therefore, improving these shortcomings is one of the primary challenges of this new design. Summary of the Invention

[0003] To address the deficiencies in conventional knowledge, this invention provides a milling tool for disc brake caliper seats. Its main purpose is to remove the paint around the screw holes of the caliper seat, creating a smooth surface.

[0004] To achieve the above objectives and effects, this invention proposes a milling tool for a disc brake caliper seat, comprising: a mounting base having accommodating portions located at both ends of the bottom and pivot members adjacent to the inner sides of the accommodating portions, the accommodating portions having accommodating holes penetrating the bottom of the mounting base; a grinding wheel pivotally mounted to the accommodating hole and protruding from the accommodating hole at the bottom, the bottom surface of the grinding wheel having a grinding surface; an operating member having a knob and a rotating shaft connected in the longitudinal direction, the knob being located at the upper middle of the mounting base, the rotating shaft penetrating the interior of the mounting base and abutting against its bottom; a gear assembly located inside the mounting base and having a first gear, a second gear, and a third gear that mesh horizontally with each other, the first gear being sleeved on the rotating shaft, the second gear being connected to the top of the grinding wheel, and the third gear being sleeved on the pivot member and located between the first gear and the second gear; and a locking fastener penetrating both ends of the mounting base and movably passing through the third gear and the grinding wheel.

[0005] The grinding wheel has a complex array of connectors protruding from its top, and the second gear has a complex array of connector holes that connect with the complex array of connectors.

[0006] The mounting base has an upper cover and a lower cover that are connected to each other. The upper cover, the grinding wheel and the second gear are respectively provided with a first through hole, a second through hole and a third through hole.

[0007] The knob is located on the outer surface of the upper cover, and the rotating shaft passes through the mounting base and rests against the inner surface of the lower cover.

[0008] The accommodating part and the pivot are located on the lower cover, and the accommodating hole penetrates the lower cover.

[0009] The fastener is sequentially inserted through the first through hole, the third through hole and the second through hole, and the top of the fastener has a locking part, which is exposed above the top cover and corresponds to the first through hole.

[0010] The mounting base is installed on the caliper seat, which has a screw hole. The inner surface of the screw hole and the outer surface of the locking fastener have corresponding internal and external thread sections.

[0011] In this process, the fastener is locked into the screw hole, and the grinding surface of the grinding wheel is in contact with the outer periphery of the caliper seat located in the screw hole. By turning the knob, the grinding wheel is driven to rotate by the gear assembly, so that the outer periphery of the caliper seat located in the screw hole forms a flat surface.

[0015] Please refer to Figures 1 through 6. This novel invention is a milling tool for a disc brake caliper seat, comprising:

[0016] Mounting base 1 has an upper cover 10 and a lower cover 11 that are connected to each other. The upper cover 10 has a first through hole 100. The lower cover 11 at the bottom of the mounting base 1 is provided with a receiving portion 12 at both ends and a pivot member 13 adjacent to the inner side of the receiving portion 12. The receiving portion 12 has a receiving hole 120 that penetrates the lower cover 11.

[0017] The grinding wheel 2 is pivotally mounted in the receiving hole 120 and its bottom protrudes out of the receiving hole 120. The top of the grinding wheel 2 is provided with a complex array of connectors 20 and the bottom surface has a grinding surface 21. The grinding wheel 2 is also provided with a second through hole 22 corresponding to the first through hole 100.

[0018] The operating component 3 has a knob 30 and a rotating shaft 31 connected in the longitudinal direction. The knob 30 is located above the upper cover 10 of the mounting base 1 and in the middle. The rotating shaft 31 passes into the interior of the mounting base 1 and abuts against the lower cover 11 at its bottom.

[0019] Gear assembly 4 is located inside mounting base 1 and has a first gear 40, a second gear 41 and a third gear 42 that mesh horizontally with each other. The first gear 40 is sleeved on the rotating shaft 31. The second gear 41 has multiple sets of meshing holes 410 and a third through hole 411 corresponding to the first through hole 100 and the second through hole 22. The multiple sets of meshing holes 410 of the second gear 41 are connected to the multiple sets of meshing parts 20 of the grinding wheel 2 so that the second gear 41 is connected to the top of the grinding wheel 2. The third gear 42 is sleeved on the pivot 13 and located between the first gear 40 and the second gear 41.

[0020] The locking fastener 5 passes through the mounting base 1 and is sequentially inserted into the first through hole 100 of the upper cover 10, the third through hole 411 of the second gear 41, and the second through hole 22 of the grinding wheel 2. The top of the locking fastener 5 has a locking portion 50, which is exposed above the upper cover 10 and corresponds to the first through hole 100. In this embodiment, the locking portion 50 is cylindrical, and the locking fastener 5 is a body extending from the locking portion 50 with an external threaded section 51 on its outer surface.

[0021] The foregoing describes the main technical features of the present invention's primary embodiment, thus revealing the purpose and implementation of the present invention. The following further describes the implementation methods of the present invention:

[0022] Please refer to Figures 5 and 6. This new type of vehicle is used with a frame. In this embodiment, the frame has a caliper seat 6, which has a screw hole 60. The inner surface of the screw hole 60 has an inner thread section 600 corresponding to the outer thread section 51 of the locking fastener 5. The outer surface of the caliper seat 6 is coated with paint, and part of the paint is located around the screw hole 60 (not shown). In use, the mounting base 1 is installed on the caliper seat 6 and the locking fastener 5 is aligned with the screw hole 60. The locking part 50 is rotated by external force to lock the locking fastener 5 into the screw hole 60, thereby locking the mounting base 1 and the caliper seat 6 together. Then, the knob 30 is rotated to rotate the rotating shaft 31, which drives the first gear 40 on the rotating shaft 31 and the third gear 42 on the pivot 13 to rotate, thereby driving the second gear 40 to rotate. Gear 41 rotates, and grinding wheel 2 rotates synchronously with second gear 41. At this time, since the grinding surface 21 of grinding wheel 2 is in contact with the outer periphery of screw hole 60, when second gear 41 rotates, its grinding surface 21 begins to grind and remove the paint around the outer periphery of screw hole 60, thereby making caliper seat 6 form a flat surface around screw hole 60. This allows caliper seat 6 to maintain a good perpendicular or parallel relationship with brake disc (not shown) after assembly through screw hole 60, avoiding affecting the operation of brake disc. Accordingly, the technical feature of this new invention only requires rotating knob 30 of operating component 3, which, in conjunction with gear assembly 4, drives grinding wheel 2 to rotate, achieving the effect of removing paint around screw hole 60 of caliper seat 6, improving the efficiency of paint removal for operators.
