Perforating machine with automatic clamping function for precision machining

Abstract

The invention discloses a perforating machine with an automatic clamping function for precision machining. The perforating machine comprises a fixing base, the upper surface of the fixing base is fixedly connected with a first motor, the output end of the first motor is fixedly connected with a rotating rod, and the end, far away from the first motor, of the rotating rod is fixedly connected witha perforating knife; a driving box is fixedly connected to the upper surface of the fixing base, a second motor is fixedly connected to the inner bottom wall of the driving box, and the output end ofthe second motor is fixedly connected with a threaded rod; the inner side wall of the driving box is fixedly connected with a first sliding rail, and the side surface, far away from the first slidingrail, of the driving box is provided with a through hole; and a threaded ring sleeves the outer surface of the threaded rod, one side surface of the threaded ring is fixedly connected with a sliding rod, the end, far away from the threaded ring, of the sliding rod is fixedly connected with a sliding block, and the sliding block is clamped inside the first sliding rail. The perforating machine withthe automatic clamping function for precision machining has the advantages of being simple in structure, high in working efficiency and capable of carrying out automatic clamping.

Description

technical field [0001] The invention relates to the technical field of precision machining, in particular to an automatic tightening punching machine for precision machining. Background technique [0002] Precision machining belongs to finishing machining in mechanical processing. According to the temperature state of the workpiece to be processed, it is divided into cold processing and hot processing. Generally, it is processed at room temperature and does not cause chemical or phase changes of the workpiece. It is called cold processing. Processing at or below normal temperature will cause chemical or phase changes of the workpiece, which is called thermal processing. For mechanical processing, processing accuracy refers to the tolerance range between the actual value after processing and the design theoretical value. [0003] There are many types of precision machining equipment. Drilling machine is a common machine in precision processing machinery. Automatic drilling ma...
