Abstract

The invention relates to a leaf spring numerical control boring device and a special clamp, and belongs to the technical field of leaf spring machining and assembling production equipment and technology. The leaf spring numerical control boring device and the special clamp are characterized in that the special clamp comprises a clamp installation frame body, a spring eye clamping device and an archeight control device, wherein a front sliding rail and a rear sliding rail are arranged on the clamp installation frame body, the spring eye clamping device comprises a fixed clamping end and a movable clamping end, the fixed clamping end is fixedly installed at the right end of the front sliding rail, and the movable clamping end is installed at the left end of the front sliding rail and can move along the front sliding rail; and hydraulic three-jaw chucks are installed on the fixed clamping end and the movable clamping end respectively, and the hydraulic three-jaw chucks can clamp the outer peripheral wall of the spring eye. According to the leaf spring numerical control boring device and the special clamp, clamping-fixing and boring-milling operations can be carried out on the springeyes with different specifications, the production efficiency is effectively improved, and the production cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of leaf spring processing and assembly production equipment and technology, and in particular relates to a leaf spring numerical control boring equipment and a special fixture. Background technique [0002] Leaf Spring Leaf Spring is the most widely used elastic element in automobile suspension. It is composed of several alloy spring sheets with equal width but unequal length (the thickness can be equal or not). An elastic beam of approximately equal strength. When the leaf spring is installed in the automobile suspension and the vertical load it bears is positive, each spring leaf is deformed by force and tends to arch upward. At this time, the axle and frame are close to each other. When the axle and frame move away from each other, the positive vertical load and deformation of the leaf spring gradually decreases, and sometimes even reverses. The flat rectangular steel plate is curved, and the chassis i...
