Embodiment Construction
[0017] The clamping of the motor housing (11) is based on the processing technology positioning reference of the motor housing (11). The motor case (11) is installed on the clamping mechanism of the motor case (11) in order to process the inner hole and the front end of the motor case (11). The positioning reference of this procedure is above the installation base plate of the motor housing (11). Like this, when taking the endoporus of motor housing (11) and the front end face as the bottom surface of the installation base plate of benchmark processing motor housing (11) afterwards, the installation base plate of motor housing (11) can be even in thickness. The positioning of the left and right directions of the motor housing (11) is realized with positioning screws (6), and the four positioning screws (6) are respectively supported on both sides of the installation base plate of the motor housing (11); the motor housing (11) The tops of the front and rear cuboids on the base...

The invention relates to a clamping mechanism for a motor shell and a method for preventing deformation of the motor shell in the clamping process. Front and rear pressure plates are arranged on the upper surface of a cuboid on the upper surface of a bottom plate. The overall upper surface of the cuboid is in a plane parallel to the lower surface of the bottom plate. An adjusting bolt is arrangedon the rear pressure plate. Two corners at the front part of the upper surface of the bottom plate of the motor shell are abutted against the bottom surface of the front pressure plate. A corner at the rear part of the upper surface of the bottom plate of the motor shell is abutted against the bottom surface of the rear pressure plate. The adjusting bolt is pressed against the other corner on theupper surface of the bottom plate of the motor shell. In the utility model, the bottom surface of the bottom plate of the motor shell is pressed on a lifting inclined block and is pressed by a positioning screw; the front and rear pressure plates are arranged on the upper surface of the cuboid; the lifting inclined block ascends, so that the two corners at the front part of the upper surface of the bottom plate of the motor shell are abutted against the bottom surface of the front pressure plate and the one corner at the rear part of the bottom plate of the motor shell is abutted against the bottom surface of the rear pressure plate; according to the indication of a dial indicator, the other corner at the rear part of the bottom plate of the motor shell is fixed, so that the clamped motorshell is not deformed.
Description
technical field [0001] The invention relates to mechanical technology equipment, especially a clamping mechanism of a motor casing and a method for preventing deformation during clamping. Background technique [0002] In the processing of mechanical parts, the parts must first be clamped on the machine tool through fixtures. To ensure the machining accuracy of the parts, it is necessary to ensure that the parts are not deformed when they are clamped. In the past, when processing thin-walled parts, it was often measured after the parts were processed on the machine tool. The size was qualified, and the shape tolerance was unqualified after being removed from the fixture. Seriously affect the quality of the parts, and some of them are waste products due to excessive deformation. The motor casing is a typical thin-walled part. The deformation caused by clamping during processing has not been completely avoided in the past, and the processing quality is unstable. Contents of ...
