Description

Technical Field

[0001] The utility model relates to a mechanical processing clamping device, in particular to a mechanical processing clamping device for an end cover of a motor. Background Art

[0002] In the machining, inspection, assembly, welding and heat treatment processes of mechanical manufacturing, a large number of fixtures are used to install the processing objects so that they occupy the correct position to ensure the processing quality of parts and products and improve production efficiency.

[0003] End caps, a type of disc-type component, are common in mechanical manufacturing and have a wide range of uses, primarily as end caps for motor components and other machinery. However, they also have other important applications: 1. Most end caps have a hole in the middle, allowing the shaft to pass through and engage with it, providing a positioning function. 2. Once installed, the end cap is airtight and can be installed behind the motor, acting as a seal. Installing the motor and the seal together prevents the ingress of foreign matter. 3. Connecting the end cap secures the motor in the desired position, a common practice on lathes, and allows for torque transmission. Because motors experience significant vibration during operation, these end caps can also be used to buffer vibrations, ensuring smoother machine operation. Currently, there is no dedicated fixture for machining the end face and aperture of this motor end cap. To ensure efficient and convenient processing, guaranteed quality, improved yield rates, and a cost-effective approach to time and labor, a dedicated fixture is required. Utility Model Content
