Description

Technical Field

[0001] The utility model relates to the technical field of brake disc processing, in particular to a high-efficiency clamp for processing a brake disc. Background Art

[0002] Electromagnetic brakes are brakes that use electromagnetic effects to achieve braking. Electromagnetic brakes are an ideal automated actuator in modern industry. They mainly play the role of transmitting power and controlling motion in mechanical transmission systems. They have the advantages of compact structure, simple operation, sensitive response, long life, reliable use, and easy remote control.

[0003] After searching the Chinese patent with publication number CN219987348U, an efficient clamp for processing the brake disc of the electromagnetic brake is disclosed. The screw rod is set to convert the rotational motion into linear motion, which can drive the lower jaw to move quickly. The lower jaw is equipped with a lower embossed plate, and the fixed upper jaw is equipped with an upper embossed plate. The upper and lower embossed plates are embossed with anti-slip treatment, so the brake disc of the electromagnetic brake can be stably clamped, ensuring the processing accuracy of the brake disc. A qualified brake disc can generate sufficient friction torque between the brake pad and the flange, which is efficient and reliable.

[0004] Based on the above search and combined with the prior art, it was found that the above patent has certain defects. When in use, the brake disc is placed on the lower embossed plate, and then it rises close to the upper embossed plate to clamp it, the brake disc is easily displaced, resulting in the phenomenon of skewed clamping, and the brake disc cannot be guaranteed to be located in the middle position of the embossed plate before being clamped, which reduces the processing efficiency of the brake disc.

[0013] First, the utility model is provided with an upper embossed plate, a lower embossed plate, a side embossed plate, a bidirectional screw and a gear. The gear on the bidirectional screw in the bracket drives the bidirectional screw to rotate under the action of the rack, so that the side embossed plates on both sides are brought closer to the middle. Before the upper embossed plate contacts the brake disc body, the side embossed plate will first push the brake disc body to a limited position in the middle position, ensuring that the upper embossed plate and the lower embossed plate clamp the brake disc body in the middle position for convenient processing. By controlling the lifting and lowering of the upper embossed plate, the brake disc body is placed on the lower embossed plate to remain stationary for greater stability, and before clamping, the side embossed plates on both sides will push the brake disc body toward the middle, ensuring that the brake disc body is located in the middle after clamping for greater convenience in processing. The clamping of both sides also increases the structural stability, thereby improving the processing efficiency of the brake disc.

[0014] Second: The utility model is provided with rubber pad one, rubber pad two, rubber pad three and a pointer. The friction of the structure is further improved by providing rubber pad one, rubber pad two and rubber pad three. A pointer is provided at the bottom of the upper embossed plate, which cooperates with the scale mark at the bottom of the positioning frame to facilitate workers to control the descending speed of the upper embossed plate in advance, avoid wear caused by strong impact, and improve the practicability of the clamp.
