Description

Technical Field

[0001] The utility model relates to the technical field of positioning devices, in particular to a brake pad steel back drilling positioning device. Background Art

[0002] Brake pads refer to friction materials fixed on brake drums or brake discs that rotate with the wheels. The friction linings and friction blocks bear external pressure, generating friction to achieve the purpose of slowing down the vehicle. Brake pads are generally composed of steel plates, adhesive insulation layers and friction blocks. The steel plates of brake pads are also called steel backs. During the production process of brake pads, it is necessary to drill holes on the side of the steel backs. The thickness of the steel backs is thin, and precise positioning is required during the drilling process. In the actual production process, the steel backs are usually placed to the drilling position manually, the workpiece is clamped manually, and then the drilling machine is used to drill. However, drilling holes on the steel backs is generally mass-produced, and manual clamping of the workpiece is inefficient and labor-intensive, which will lead to a decrease in production efficiency and increase production costs.

If the steel back is not placed in an accurate position, the two clamping plates 3 can clamp the two sides of the steel back to move the steel back to the specified position. While the two clamping plates 3 are clamped, the support plate 2 moves toward the side close to the steel back at the same time, so that the clamping assembly presses the steel back, so that the steel back and the positioning strip 5 fit tightly, thereby achieving accurate positioning of the steel back. After positioning is completed, the second transmission assembly drives the two clamping plates 3 to move away from each other, so that the clamping plates release the steel back. At the same time, the first transmission drilling drives the support plate 2 to move away from the steel back, and the clamping assembly separates from the steel back. At this time, the accurate positioning of the steel back can be completed, and drilling can be more accurate. At the same time, clamping and positioning are faster and more convenient, which is suitable for large-scale steel back production and improves production efficiency.
