Turning device and straightening machine for heavy shaft parts

Abstract

The invention discloses a turnover device of a heavy shaft part, which comprises an outer V-shaped frame, an internal support frame, a hydraulic lifting cylinder, a turnover transmission mechanism and a drive mechanism, wherein the internal support frame is located in the outer V-shaped frame; the hydraulic lifting cylinder is located outside the internal support frame; an axial direction of the hydraulic lifting cylinder is parallel to a longitudinal direction of the internal support frame; the hydraulic lifting cylinder is fixedly connected with the internal support frame; the turnover transmission mechanism is fixed in the internal support frame; a highest point of the turnover transmission mechanism exceeds the upper end face of the internal support frame; the turnover transmission mechanism is connected with the drive mechanism; and the drive mechanism is located in or outside the internal support frame. The device can support the thermally treated shaft part and drive the shaft part to turn over.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a turning device and straightening machine for heavy-duty shaft parts. Background technique [0002] For the obtained heavy-duty elongated shaft parts after heat treatment, they need to be machined before they can be used. Since the shaft parts will be bent and deformed during the heat treatment process, it cannot be directly machined. Therefore, the usual practice is to place the shaft parts on the press and straighten them to the range that can be processed. However, in straightening, the workpiece is placed on the V-shaped iron of the press, and the V-shaped iron only supports the shaft parts and has no function of driving the workpiece to rotate. Therefore, how to move and turn the workpiece is a difficult problem. For the above-mentioned presses, the shaft parts are often turned over manually. Since the heat-treated shaft parts still have a high temperature, i...

Problems solved by technology

However, in straightening, the workpiece is placed on the V-shaped iron of the press, and the V-shaped iron only supports the shaft parts and has no function of driving the workpiece to rotate. Therefore, how to move and turn the workpiece is a difficult problem

For the above-mentioned presses, the shaft parts are often turned over manually. Since the heat-treated shaft parts still have a high temperature, if the operation is not careful, the operator will be scalded, and because the weight of the workpiece is heavy, Manual flipping is time-consuming and laborious
