Description
Pre-grinding machine for bearing plates Brake Pad Bedding Machine Technical Field
[0001] This invention relates to the technical field of bicycles, and in particular to a brake pad pre-grinding machine. Prior Technology
[0002] Among bicycle components, the braking system directly affects rider safety, making its performance and quality paramount. Among various braking systems, drum brakes and disc brakes are the most common, with disc brakes increasingly becoming a market trend due to their ease of operation, high safety, and superior performance. Disc brake systems primarily utilize the friction between the brake pads and the disc to slow down or stop the vehicle; therefore, the break-in period between the two is crucial. Improper break-in between the brake pads and the disc not only produces sharp, piercing braking noises but also poses a significant safety hazard to the rider.
[0003] To avoid improper break-in between brake pads and discs, bicycle mechanics often use a brake pad bedding machine to pre-break in new brake pads and discs under controlled conditions, ensuring uniform and stable friction contact surfaces. However, conventional brake pad bedding machines are bulky, and their operation usually requires mounting the brake pads on the target – the "finished bike" – making it impossible to bend in a single brake pad and disc. This not only requires ample operating space but also makes the process relatively laborious and cumbersome.
[0004] Therefore, the creator has devoted a lot of time to studying relevant knowledge, comparing the advantages and disadvantages of various products, conducting research and development on related products, and going through many experiments and tests, and finally launched a brake pad pre-grinding machine that can solve the above-mentioned shortcomings, so as to meet the needs of the public. Summary of the Invention
[0005] The main purpose of this invention is to provide a brake pad pre-grinding machine to achieve the effect of grinding brake pads and discs in a compact, easy-to-operate, and portable manner.
[0006] To achieve the aforementioned effects and improve upon the deficiencies of prior art, this invention provides a brake pad pre-grinding machine for pre-grinding multiple brake pads, comprising: a machine body having an actuating part, the actuating part having an accommodating space inside, and an actuating port on one side of the actuating part communicating with the accommodating space; a main control unit located within the accommodating space, and the main control unit having a main control unit; and a servo motor located within the accommodating space, the servo motor being connected to the main control unit. The control unit is electrically connected; a rotating shaft is located within the accommodating space and connected to the servo motor, and a disc is disposed on the rotating shaft and corresponds to the actuation port; two brake members are located within the accommodating space and are disposed opposite each other near the actuation port, and each brake member is electrically connected to the main control unit; two clamping members are located in the actuation port and are respectively connected to one end of each brake member and are disposed opposite each other, and each clamping member has a locking groove on the surface of its side facing each other.
[0007] When the main control unit controls the servo motor to start, the servo motor drives the rotating shaft and the disc to rotate, and the main control unit controls each brake to push each clamping component to move closer to each other. Simple Explanation of the Diagram

[0009] To provide a more detailed understanding of the embodiments of this invention, the features and effects of the embodiments are described in detail with reference to the accompanying drawings. Referring to Figures 1 to 8, this invention provides a brake pad pre-grinding machine for pre-grinding multiple brake pads 8, comprising: a machine body 1, the machine body 1 having an actuating part 11, the actuating part 11 having an accommodating space 111 inside, and an actuating port 112 on one side of the actuating part 11 communicating with the accommodating space 111; a main control unit 2, the main control unit 2 being located within the accommodating space 111, and the main control unit 2 having a main control unit 21; and a servo motor 3, located within the accommodating space 111, and the servo motor 3 being connected to the main control unit. 21 Electrical connection; a rotating shaft 4, which is located in the accommodating space 111 and connected to the servo motor 3, and a disc 7 is disposed on the rotating shaft 4 and corresponds to the actuation port 112; two brake members 5, which are located in the accommodating space 111 and are disposed opposite each other near the actuation port 112, and each brake member 5 is electrically connected to the main control unit 21; two clamping members 6, each clamping member 6 is located in the actuation port 112 and is respectively connected to one end of each brake member 5 and is disposed opposite each other, and each clamping member 6 has a locking groove 61 on the surface of the side facing each other.
[0010] In use, the user places the two brake pads 8 to be broken in into their respective slots 61 and activates the main control unit 2. The main control unit 21 controls the actuators 5 to push the clamping members 6 closer together, so that the brake pads 8 come into contact with the disc 7. At the same time, the main control unit 21 of the main control unit 2 controls the servo motor 3 to start, which drives the rotating shaft 4 and the disc 7 to rotate, so that the brake pads 8 and the disc 7 can be broken in. With a relatively lightweight design, it achieves the effects of being easy to carry, easy to operate, and effectively breaking in the brake pads 8 and the disc 7, as shown in Figures 1, 3 to 6.
[0011] Based on the above description, the following further describes other technical and structural features of this invention. To avoid excessive or improper break-in between the brake pads 8 and the disc 7, the surface of the body 1 is further provided with a display 12. The display 12 is electrically connected to the main control unit 2, and the main control unit 2 is further provided with a friction coefficient measuring unit 22. The servo motor 3 is further provided with a torque measuring unit 31, and each brake 5 is further provided with a pressure measuring unit 511. The friction coefficient measuring unit 22 calculates the friction coefficient between the brake pads 8 and the disc 7 based on the values detected and converted by the torque measuring unit 31 and the pressure measuring unit 511, and displays it on the display 12, allowing the user to confirm whether the break-in is complete through the display 12, as shown in Figures 1 and 7.
[0012] The formula used by the torque measurement unit 31 is as follows: f represents the friction force value calculated by the torque measurement unit 31. T represents the torque value measured by the torque measuring unit 31. r represents the effective friction radius of the disc 7.
[0013] The torque measuring unit 31 utilizes the aforementioned values (T, r), and convert it according to the following formula:
[0014] The formula used in the friction coefficient measurement unit 22 is characterized as follows: μ represents the coefficient of friction between the brake pad 8 and the disc 7. f represents the friction force value calculated by the torque measuring unit 31 based on the measured torque value (T). N represents the pressure value measured by the pressure measuring unit 511.
[0015] The friction coefficient measuring unit 22 uses the aforementioned values (f, N) and calculates them according to the following formula:
[0016] An external control unit 9 (e.g., computer, mobile phone, tablet, etc.) is also provided. This external control unit 9 is electrically connected to the main control unit 2 and has a setting unit 92. When the user needs to set the rotation speed of the servo motor 3 and the preset pressure of each brake 5, they only need to operate the setting unit 92 of the external control unit 9 to adjust the servo motor 3 and each brake 5 through the main control unit 21 of the main control unit 2. In addition, the external control unit 9 can also display the values detected by the torque measuring unit 31 and the pressure measuring unit 511, as well as the friction coefficient calculated by the friction coefficient measuring unit 22, and simultaneously store the various data mentioned above in a database 91, providing users with centralized data management and subsequent applications, such as product sampling yield testing, bicycle maintenance records, etc., as shown in Figure 7.
[0017] Each actuator 5 further includes a hydraulic cylinder 51 and a telescopic member 52. The two ends of the telescopic member 52 are respectively connected to the hydraulic cylinder 51 and each clamping member 6. The hydraulic cylinder 51 pushes the telescopic member 52 to cause the clamping members 6 to move closer or further apart. The user can adjust the pressure continuously applied by the hydraulic cylinder 51 to the telescopic member 52 (i.e., the aforementioned pressure value N, for example: 100 kgf...) by operating the external control 9. In addition to being able to accommodate various thicknesses of the brake pads 8, the continuous pressure makes the break-in process stable and the surface of each brake pad 8 is evenly stressed and uniformly broken in, as shown in Figures 3 to 6.
[0018] The device 1 has a power button 13 on its surface. The power button 13 is electrically connected to the main control 2. Pressing the power button 13 turns the main control 2 on or off, as shown in Figures 1, 2, 3, and 5.
[0019] The body 1 further includes a hand-held part 14, which is connected to the actuating part 11. The hand-held part 14 allows the user to easily hold and carry the device without being limited by the size of the space, thus improving convenience, as shown in Figures 1, 2, 3, and 5.
[0020] The body 1 further includes a storage slot 151 and a storage component 152. The storage component 152 is normally located in the storage slot 151 and can move in and out of the storage slot 151. The storage component 152 provides users with temporary storage or frequently used spare parts without having to retrieve them each time, thereby improving convenience, as shown in Figures 1, 2, 3, and 5.
[0021] Please also refer to Figure 8, which is a block diagram of the second embodiment of this invention. In this embodiment, the configuration and operation of components with the same component symbols are the same or similar to those in the aforementioned embodiments, and the similarities will not be repeated here. The main difference between this embodiment and the aforementioned embodiments is that the setting unit 92 is located on the display 12, making the display 12 an operable interface. When the user does not need to store the measurement data, the user does not need to operate the external control component 9 separately, but only needs to operate the display 12 to set the rotation speed of the servo motor 3 and the preset pressure of each brake component 5, thereby reducing the number of spare parts required, improving overall convenience, and allowing the user to choose according to their needs, reducing the user's purchase cost pressure.
[0022] In conclusion, this novel "brake plate pre-grinding machine" fully meets the needs of industrial development in terms of practicality and cost-effectiveness. Furthermore, the disclosed structural design is an unprecedented innovative construction, so its "novelty" is beyond doubt. Moreover, this novel design offers greater efficiency than conventional structures, thus also possessing "progressiveness."
