Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing equipment, in particular to a vertical machining center machine tool protection device. Background Art

[0002] The gearbox used in automobiles is a key transmission component. Its main functions include speed change, power transmission and torque adjustment. It is usually composed of multiple gears, drive shafts and bearings. The power transmission and speed change are achieved through the meshing of gears.

[0003] In the process of gearbox production and processing, a lost foam production line is usually used to produce gearbox castings with complex shapes and high precision to improve the overall quality and performance of the gearbox. After that, a shot blasting machine is used to remove defects such as scale and sand adhesion on the casting surface to improve the surface quality and finish of the gearbox. When processing the gearbox, a vertical machining center machine tool protection device is usually used to connect with the installation station to isolate the chips or fragments generated by the lost foam production line or shot blasting machine and other equipment during operation, reducing the risk of injury to operators.

[0004] During the use of the existing vertical machining center machine tool protection device, although it can be connected to the installation station by tightening screws, the vibration and dynamic load generated by the operation of equipment such as the lost foam production line or shot blasting machine will gradually overcome the friction generated by the screws, causing them to loosen, thereby reducing the protective effect of the vertical machining center machine tool protection device. Finally, chips or fragments will be splashed when the lost foam production line or shot blasting machine and other equipment are in operation, causing harm to the staff. For this reason, we propose a vertical machining center machine tool protection device. Utility Model Content
