[0002] Brake pads are a crucial component of the braking system, playing a vital role in directly contacting the brake disc and achieving deceleration and stopping. Brake pads are typically installed within the brake caliper. When the driver depresses the brake pedal, the caliper presses the brake pads against the brake disc, creating friction and reducing vehicle speed. Brake pad stretching generally refers to the tensile deformation that occurs in the brake pads under stress. The brake pad stretching point is the location where the brake pad needs to be stretched during braking, usually located at the contact surface between the brake pad and the brake disc. During braking, the brake pads are stretched under pressure, generating friction with the brake disc to achieve the braking effect.

[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 1-6 As shown, a brake pad anti-sag tooling includes a positioning mounting plate 1 for fixing the tooling in a suitable position. A support height adjustment structure 2 is provided on one side of the positioning mounting plate 1 for adjusting the height of a support adjustment platform 3 to adapt to different working environments or requirements. The support adjustment platform 3 is mounted on the support height adjustment structure 2 to support the brake pad. A depth adjustment structure 4 is provided inside the support adjustment platform 3, and a support limiting frame 5 is installed inside the depth adjustment structure 4. A machining height adjustment structure 6 is designed on the outside of the support height adjustment structure 2 for adjusting the height of a stretching operation platform 7. The stretching operation platform 7 is mounted on the machining height adjustment structure 6. A telescopic control structure 8 is provided inside the stretching operation platform 7 for controlling the telescopic movement of a stretching working block 9 to achieve the stretching operation of the brake pad. The stretching working block 9 is clamped onto the outside of the telescopic control structure 8, directly acting on the brake pad to achieve the stretching operation.
[0023] The height adjustment support structure 2 includes a support threaded rod 201, which is rotatably engaged with both sides of the positioning mounting plate 1. A linkage sprocket 202 is fixedly fitted onto the lower end of the support threaded rod 201, and a linkage chain 205 is meshed onto the outer side of the linkage sprocket 202. A positioning gear ring 203 is fixedly installed on the support threaded rod 201. A support motor 204 is embedded in the inner side of the positioning mounting plate 1, and a drive gear is fixedly installed at the output end of the support motor 204. The drive gear meshes with the positioning gear ring 203. First, starting the support motor 204 on the inner side of the positioning mounting plate 1 will cause the drive gear to rotate. The drive gear meshes with the positioning gear ring 203. The engagement of the gear ring 203 transmits the rotational power of the motor to the support threaded rod 201. As the drive gear rotates, the support threaded rod 201 also begins to rotate. Due to the rotational engagement between the threaded rod and the positioning mounting plate 1, the rotation of the threaded rod is converted into the vertical movement of the support adjustment platform 3. At the same time, the linkage sprocket 202 and the linkage chain 205 ensure the synchronous rotation of the support threaded rods 201 on both sides, thereby maintaining the smooth lifting and lowering of the support adjustment platform 3. By continuously controlling the rotation of the motor, the height of the support adjustment platform 3 can be gradually adjusted until the required working position is reached. When the support adjustment platform 3 reaches the required height, the support motor 204 is turned off, completing the height adjustment process.
[0024] The depth adjustment structure 4 includes a combination retaining ring 401. A power mounting groove is provided on the outer side of the depth adjustment retaining hole. The combination retaining ring 401 and the lower side of the power mounting groove are slidably engaged. A depth adjustment gear ring 402 is rotatably engaged on the upper side of the combination retaining ring 401. A depth adjustment threaded hole is provided inside the depth adjustment gear ring 402. A depth adjustment motor 403 is embedded in one side of the power mounting groove. An adjusting gear is fixedly installed at the output end of the depth adjustment motor 403. The adjusting gear meshes with the depth adjustment gear ring 402. A support threaded hole is provided at one end of the support adjustment platform 3. The support threaded hole and the support threaded rod 201 are threadedly connected. A depth adjustment retaining hole is provided at one end of the support adjustment platform 3. A support limiting frame 5 is installed inside the depth adjustment retaining hole. A limiting groove is designed on the outer side of the power mounting groove. A limiting protrusion is provided on the outer side of the support limiting frame 5. The limiting protrusion and the limiting groove are slidably engaged. The outer side of frame 5 is provided with upper and lower spiral threads, which are threadedly connected to the depth adjustment threaded hole. When the depth adjustment motor 403 is started, the rotation of the motor is transmitted to the depth adjustment gear ring 402 through the adjusting gear. The rotation of the depth adjustment gear ring 402 is connected to the depth adjustment threaded hole and the upper and lower spiral threads through the thread, driving the support limit frame 5 to move up and down, thereby achieving precise adjustment of the processing depth of the brake pad. The support limit frame 5 is slidably engaged with the limit protrusion and the limit slide groove, ensuring the stability of the support limit frame 5 during the depth adjustment process and preventing displacement or shaking caused by vibration or external force. Through the coordinated work of the support height adjustment structure 2 and the depth adjustment structure 4, the height and depth of the brake pad tooling can be adjusted to meet different processing needs and working environments. The design of the depth adjustment structure 4 makes the connection and disassembly between the various components relatively simple, which is convenient for daily maintenance and upkeep.
[0025] The height adjustment structure 6 includes a threaded rod 601, which is rotatably engaged with both sides of the positioning mounting plate 1. A synchronous sprocket 602 is fixedly mounted on the lower end of the threaded rod 601, and a synchronous chain 603 is engaged with the outer side of the synchronous sprocket 602. A driven gear ring 604 is fixedly mounted on the threaded rod 601. A processing motor 605 is embedded in the inner side of the positioning mounting plate 1. A power gear is fixedly mounted on the output end of the processing motor 605. The power gear and the driven gear ring 604 mesh with each other. When the processing motor 605 is started, the rotation of the motor is transmitted to the driven gear ring 604 through the power gear, thereby driving the threaded rod 601 to rotate. Since the threaded rod 601 and the positioning mounting plate 1 are rotatably engaged, the rotation of the threaded rod is converted into vertical movement, thereby realizing the height adjustment of the processed part.
[0026] One end of the stretching operating table 7 has a stretching threaded hole, which is threadedly connected to the threaded rod 601. Another end of the stretching operating table 7 has a stretching power groove, and the stretching work block 9 is installed inside the stretching power groove. The telescopic control structure 8 includes a lever gear 801, which is rotatably engaged inside the stretching power groove. A stretching motor 802 is embedded in one side of the stretching power groove, and a drive gear is fixedly installed at the output end of the stretching motor 802. The drive gear meshes with the lever gear 801. When the stretching motor 802 is started, its rotation is transmitted to the lever gear through the drive gear. Wheel 801 drives the extension threaded rod 803 to rotate. Since the extension threaded rod 803 is threadedly connected to the extension threaded groove of the stretching working block 9, the rotation of the extension threaded rod 803 is converted into the vertical movement of the stretching working block 9, thereby realizing the stretching operation. The extension threaded rod 803 is fixedly welded to the center of the lever gear 801. Extension grooves are provided around the stretching power groove. An extension limiting block is designed at the upper end of the stretching working block 9. The extension limiting block and the limiting groove slide against each other. The sliding engagement of the extension limiting block and the extension groove ensures the stability of the stretching working block 9 during the lifting and lowering process. This helps to reduce vibration and shaking, and improve the accuracy and efficiency of the stretching operation. The extension threaded groove is provided at the center of the stretching working block 9. The extension threaded groove is threadedly connected to the extension threaded rod 803. The height of the stretching operating table 7 can be adjusted by machining the threaded rod 601, while the lifting and lowering of the stretching working block 9 is achieved by the telescopic control structure 8. The coordinated work of these two structures makes the entire stretching operation more flexible and efficient.
