Problems solved by technology

[0002] At present, the machining of the diesel engine fan drive shaft is usually done by clamping the workpiece on the lathe with a lathe chuck, and then processing. Since the diesel engine fan drive shaft is a thin-walled part, it is not easy to clamp during processing, such as clamping If the clamping force is too small, the tool will easily remove the parts from the machine tool during the processing of the diesel fan drive shaft, resulting in the scrapping of the diesel fan drive shaft. If the clamping force is too large, the diesel fan drive shaft is a thin-walled part, so Diesel engine fan drive shaft is easily deformed, so that the machining accuracy cannot be guaranteed

Abstract

The invention provides a clamp device which comprises a clamp body. The clamp body comprises a workpiece fixing end used for fixing a workpiece and a clamp body fixing end used for fixing the clamp body to a machine tool. The workpiece fixing end is provided with a locating shaft shoulder matched with a workpiece locating face. A locating shaft is arranged on the end face of the workpiece fixing end. The locating shaft is in threaded connection with a double-screw bolt. A nut is arranged on the double-screw bolt. The locating shaft is sleeved by a pressing board. A gap is formed between the pressing board and the end face of the workpiece fixing end. The workpiece fixing end of the clamp body is provided with the locating shaft shoulder matched with the workpiece locating face, the workpiece is sleeved on the clamp body. The workpiece is fixed on the clamp body through the double-screw bolt, the nut and the pressing board. Due to the fact that clamping force in the clamping process is in the axial direction of the workpiece, the workpiece can be clamped easily and is not prone to deformation.

Description

technical field [0001] The invention relates to a machining fixture, in particular to a fixture device. Background technique [0002] At present, the machining of the diesel engine fan drive shaft is usually done by clamping the workpiece on the lathe with a lathe chuck, and then processing. Since the diesel engine fan drive shaft is a thin-walled part, it is not easy to clamp during processing, such as clamping If the clamping force is too small, the tool will easily remove the parts from the machine tool during the processing of the diesel fan drive shaft, resulting in the scrapping of the diesel fan drive shaft. If the clamping force is too large, the diesel fan drive shaft is a thin-walled part, so Diesel engine fan drive shaft is easily deformed, so that the machining accuracy cannot be guaranteed. Contents of the invention [0003] The problem to be solved by the present invention is to provide a clamping device that is easy to clamp and can easily ensure machining ...
