Pneumatic circuit for numerically controlled lathe pneumatic door opening and closing

Abstract

The invention discloses a pneumatic circuit for a pneumatic door switch of a numerically controlled lathe, including an exhaust circuit. The exhaust circuit is provided with a high-speed, high-load pneumatic buffer circuit. The high-speed, high-load pneumatic buffer circuit includes a single-rod double-acting cylinder, a pressure-reducing valve , pressure reducing valve 2, speed regulating valve 1, speed regulating valve 2, solenoid valve 1, solenoid valve 2, solenoid valve 3, the gas source is connected to the solenoid valve 3 through the pipeline and the pressure reducing valve 1 on the pipeline, and the solenoid valve 3 is connected to the solenoid valve 3. Solenoid valve 1 is connected, solenoid valve 3 is connected with solenoid valve 2, speed regulating valve 1 is connected with the piston end cavity of the single-rod double-acting cylinder, speed-regulating valve 1 is connected with solenoid valve 1, speed-regulating valve 2 is connected with single-rod double-acting cylinder The connecting rod end cavity of the cylinder is connected, the speed regulating valve 2 is connected with the solenoid valve 2, the pressure reducing valve 2 is connected with the solenoid valve 1 and the solenoid valve 2, and the pressure reducing valve 1 and the pressure reducing valve 2 are connected with the exhaust circuit; the present invention The cushioning effect is good, reducing the impact of the sliding door, avoiding the loosening of the cylinder and sliding door guide rail screws to ensure safety and the service life of the cylinder.

Description

technical field [0001] The invention relates to the technical field of control equipment for a pneumatic door of a numerical control machine tool, in particular to a pneumatic circuit for a pneumatic door switch of a numerical control lathe. Background technique [0002] Due to the special structural requirements, the pneumatic door of CNC wheel hub car used in the prior art has a structural mass that is too large, for example, the mass will be greater than 200kg. At the same time, the customer requires the opening and closing time of the pneumatic door to be as short as possible, and some technical requirements need to be met within 5S. The inner and pneumatic doors can reach a reciprocating stroke of 900mm, minimizing the auxiliary working time of the equipment. The impact of the short switching time of the pneumatic door and the reduction of the auxiliary working time of the equipment is that the faster running speed causes large vibration, large inertia, and poor cushion...
