TECHNICAL FIELD
[0001] The present application belongs to the technical field of machinery, and particularly relates to a machining center double-leaf door opening and closing device. BACKGROUND
[0002] In the current industrial production environment, most of the traditional double-leaf door machining centers adopt a manual opening and closing mode, and the door body is equipped with a track and a sensor. The operator needs to repeatedly manually push and pull the double-leaf door to complete the opening and closing operation. However, the weight of the door body itself brings a considerable burden to the operator. With the increase of the service life of the equipment, if the lubrication and maintenance are not in place, the resistance of the push-pull door will further increase, making the operation more laborious. In order to pursue convenience, some operators of enterprises even intentionally disable the sensor and directly process in the open door state. This operation mode not only has serious safety hazards - cutting debris may fly during the processing process, which is easy to cause harm to the operator, but also causes pollution to the operating environment.
