Abstract

The invention discloses a hydraulic floating centering and clamping transmission device. A center is installed in a center hole of a cylindrical chuck body. Symmetrically-arranged semicircular clamping heads are installed in the positions, outside the tip of the center, of the center hole of the chuck body. Rectangular holes are symmetrically formed in the positions, outside the two semicircular clamping heads, of the chuck body. Hydraulic clamping devices which are the same in structure and opposite in installing direction are installed in the corresponding rectangular holes respectively and fixedly connected with the corresponding semicircular clamping heads respectively. An end cover and the outer sides of the two hydraulic clamping devices form a rolling pair. Hydraulic cylinders in the two hydraulic clamping devices are both connected to a center oil port of the chuck body through respective hoses, respective flexible connectors and a hydraulic pipeline on the chuck body respectively. Rotating connectors are connected with the center oil port of the chuck body in a threaded mode. According to the machining characteristics of shaft parts, the shaft parts can be automatically centered and clamped. A mechanical arm and a numerical control machine tool are matched, the shaft parts can be automatically produced, the influence of human factors is reduced, and product quality and production efficiency are improved.

Description

technical field [0001] The invention relates to a hydraulic clamping transmission device, in particular to a hydraulic floating centering clamping transmission device for machining parts with high coaxiality requirements. Background technique [0002] Shaft parts are a general term for a type of parts whose main body is a rotary structure, with small radial dimensions and large axial dimensions. The parts have large batches and many specifications, such as output shafts and other parts that are widely used in the automotive industry. In the manufacturing and processing of the traditional automobile industry, due to the high-precision requirements of some shaft parts, such as the high coaxiality requirements of the stepped shaft, it is necessary to adopt a variety of auxiliary methods. At present, the following three auxiliary methods are used in production: 1) Additional additional auxiliary processes, such as pre-turning the outer circle, etc., in this method, the inc...
