Embodiment

[0025] as attached figure 1 to attach Figure 5 Shown:

[0026] The present invention provides a special fixture structure for a large power brake drum, which includes a brake drum 11, an upper cylindrical surface 12, a lower cylindrical surface 13, a chuck seat 1, a claw bracket 2, a claw 3, a claw seat 31, a Claw body 32, rubber contact 321 and hinge shaft 4; the brake drum 11 includes an upper cylindrical surface 12 and a lower cylindrical surface 13; the bottom of the jaw bracket 2 is connected to the chuck seat 1; the jaw 3 is hinged on the claw bracket 2 through a hinge shaft 4; the claw 3 includes a claw seat 31 and a claw body 32.

[0027] Wherein, the rotation angle of the claw 3 on the claw bracket 2 is 0-30°, and the limitation of the rotation angle of the claw 3 avoids excessive rotation of the claw 3 and affects the efficiency of the next clamping.

[0028] Wherein, the claw 3 is a hoof-shaped structure, and the claw body 32 is provided with four places on the ...

Abstract

The invention provides a special fixture structure for a large power brake drum, including a chuck seat, a claw bracket, a claw, a claw seat, a claw body, a rubber contact and a hinge shaft; the bottom of the claw bracket is connected to on the chuck seat; the claw is hinged on the claw bracket through a hinge shaft; the claw includes a claw seat and a claw body. In the present invention, the clamping force of the claws on the brake drum is distributed on 12 claw bodies, and rubber contacts are provided on the contact surface between the claw bodies and the brake drum, so that the distribution of the clamping force is more uniform and avoids Solved the problem of clamping deformation of thin-walled parts. The present invention can complete the processing content of rough turning and finishing turning in one clamping, and the rotation angle of the jaws is limited within 0-30°, which avoids the excessive rotation of the jaws and affects the efficiency of the next clamping, and the auxiliary time is less and the processing efficiency is improved. high. The clamping of the invention has good adjustability and strong versatility, and can meet the processing requirements of various varieties.

Description

technical field [0001] The invention belongs to the technical field of clamp structures, and in particular relates to a special clamp structure for a large power brake drum. Background technique [0002] With the rapid development of the automobile industry, the output of automobiles continues to increase, the driving speed continues to increase, and the processing requirements for various parts of automobiles are also constantly improving. Brake drums are an important part of automobile braking. The quality of the brake directly determines the various indicators of the brake. Whether the parts processing can meet the design accuracy requirements directly affects the product quality. At present, the precision of domestic metal cutting machine tools can meet the processing needs of the hub, but the clamping accuracy and stability of the hub restrict the machining accuracy and pass rate of the hub. People have thought of many ways to meet the requirements of machining accurac...
