Hydraulic automatic centering, positioning and clamping device

Abstract

The invention discloses a hydraulic automatic centering positioning clamping device which comprises a bottom plate, a driving mechanism, a centering positioning mechanism and a jacking mechanism, the driving mechanism comprises a hydraulic motor, an input shaft and a first bevel gear, and the two ends of the input shaft are coaxially and fixedly connected with the output end of the hydraulic motor and the first bevel gear correspondingly; the centering and positioning mechanism comprises a second bevel gear and two centering and positioning units, the second bevel gear is meshed with the first bevel gear, each centering and positioning unit comprises an output shaft, the output shafts of the two centering and positioning units are symmetrically arranged and coaxially fixed to the two sides of the second bevel gear, each output shaft is provided with a threaded section, and the threaded sections are connected with the second bevel gear. The thread directions of the thread sections on the two output shafts are opposite, the jacking mechanism comprises two jacking units, and each jacking unit comprises a push rod, a jacking rod and a guide seat. According to the device, hydraulic pressure serves as power, the hydraulic motor serves as an execution element, centering, positioning and clamping of a workpiece can be achieved, time and labor are saved, and automation of workpiece clamping can be achieved conveniently.

Description

technical field [0001] The invention relates to a part positioning and clamping device in machining, in particular to a hydraulic automatic centering positioning and clamping device. Background technique [0002] Parts are the basic elements of mechanical equipment. The processing of mechanical parts is inseparable from metal cutting, and fixtures are one of the important process equipment to ensure processing efficiency and processing quality. In machining, for the clamping of the parts that need to be positioned in the middle, the traditional fixtures need to be manually aligned and clamped, which is time-consuming and labor-intensive, and it is difficult to realize automation. Especially for blank parts, because of their irregular structure and uneven machining allowance, if they are aligned and clamped improperly, it is easy to cause part offset, increase tool loss, affect machining efficiency, and in severe cases, lead to unilateral machining allowance of parts. Insuff...
