Description

Technical Field

[0001] The invention relates to the field of steel back fixtures, in particular to a brake pad steel back processing positioning and flipping fixture. Background Art

[0002] Brake pad steel back is one of the important components of brake pads. It mostly refers to the metal support sheet installed behind the friction material of the brake pad. It plays the role of supporting and fixing the friction material, so that the brake pad can work stably in the brake system, withstand the pressure and friction generated during braking, and transmit these forces to components such as brake calipers or brake shoes. Brake pad steel back is usually made by stamping or die-casting. After the steel back is initially formed, it needs to be drilled, so a steel back clamp is needed to clamp it. A Chinese utility model patent discloses a tooling fixture for processing the steel back of a brake pad (application number: 2022209345568), which is used in conjunction with structures such as a slide groove, a moving plate, a plug rod, a support plate, a top bolt, a clamping plate, and a backing plate to clamp the steel back body of a brake pad of different sizes and flip the steel back body of the brake pad; However, although the above patent content can clamp the steel back body of the brake pad, it does not provide a bottom supporting structure. When processing a thinner steel back, it is easy to cause the steel back body to be slightly bent and deformed, thereby affecting the yield rate. At the same time, the turntable in the above patent content is manually rotated and fixed by tightening bolts. When in use, the bolts need to be repeatedly turned to fix the turntable, and no adaptive loading mechanism is set, which makes the overall processing process cumbersome and complicated.

After the steel back of the brake pad is clamped, the second electric telescopic rod 26 drives the jacking mounting platform 27 to rise and press against the lower end of the steel back of the brake pad to prevent the steel back of the brake pad from bending during processing, and then the steel back of the brake pad is processed; Step 5: When the brake pad steel back needs to be rotated, the rotating disk 11 can be driven to rotate by starting the first stepper motor 12. When the brake pad steel back needs to be flipped, the first electric telescopic rod 14 drives the spur rack 16 to move.
