The working principle of the invention is as follows:
the vacuum precision casting furnace provided by the invention can be divided into three major parts according to the action, namely a turning action part, a horizontal moving part and a control part;
the turning action part executes turning casting action according to action data instructed by the controller, and the process is as follows:
the first power source is fixed on the motor fixing frame, receives a driving instruction of the controller, and drives the rotating hollow shaft in the tilting fixed hollow shaft to rotate (the tilting fixed hollow shaft is fixed and does not rotate) through the first transmission component. The rotary hollow shaft enters a vacuum cavity of the vacuum precision casting furnace through the first vacuum sealing element, and drives the smelting coil to penetrate through the smelting coil fixing frame to be fixedly connected with the end face of the rotary hollow shaft, which is positioned in the vacuum cavity of the vacuum precision casting furnace, and the rotary hollow shaft can rotate along with the rotary hollow shaft in the smelting coil fixing frame, so that the smelting coil is driven to tip over, and the rotary casting action is realized.
The horizontal moving part performs horizontal reciprocating movement to a fixed point position according to the action data instructed by the controller, and the process is as follows:
the first plate and the second plate (which are fixedly arranged) are arranged adjacently, and a second vacuum sealing element is arranged between the first plate and the second plate and is fixed on one surface of the second plate, which is adjacent to the first plate;
a horizontal movement limiting structure is formed on the second plate, and correspondingly, through holes with the same shape as the horizontal movement limiting structure are formed on the second vacuum sealing element;
a first sliding piece which is vertical to the tilting fixed hollow shaft in the horizontal direction is formed on the adjacent surface of the first plate and the second plate; a second sliding part matched with the first sliding part is formed on the surface of the second plate, which is adjacent to the first plate, the first plate is matched with the second sliding part through the first sliding part, and a second power source receives a driving instruction of a controller and drives the first plate to horizontally reciprocate in a horizontal movement limiting structure on the second plate through a driving linear actuator;
the control part comprises a sensor (an angle sensor and a distance sensor) and a controller, and the control process comprises the following steps:
the sensor collects the real-time angle of the rotating hollow shaft, the rotating angle of the rotating hollow shaft, the time from the beginning to the end of the stroke of the linear actuator driven by the second power source, and the stroke of the tilting fixed hollow shaft driven by the second power source.
The collected action data are sent to a controller, and the controller can fit the action data (for example, the turning angle of the hollow shaft and the horizontal movement stroke of the hollow shaft are X-axis, and the running time is Y-axis) to form a casting curve by establishing a rectangular coordinate system;
correspondingly, when the same product is produced subsequently, the action data corresponding to the highest casting curve of the yield is selected to perform casting, so that the uniformity problem of manual operation is solved, the product quality can be improved, and the production efficiency can be remarkably improved by realizing automatic fixed-point casting through the controller relative to the manual operation.
Or, the external action data is directly input to the controller to carry out production after simulating the action data required by casting of different products through mathematical modeling. Correspondingly, because the modeling simulation production may have deviation (the model is ideal data, and the deviation is inevitably generated due to different service life, performance and the like of production equipment in real production), a casting curve can also be established for the action data obtained by external modeling, and the action data with the highest yield in the corresponding casting curve (the action data obtained by external modeling) is selected as the action data of the controller instruction in the next production.
In conclusion, the automatic fixed-point casting device of the vacuum precision casting furnace provided by the invention can realize full-automatic fixed-point casting, and overcomes the defects that in the prior art, the uniformity of a product cast by manual operation is poor, the product quality cannot be ensured, the requirement on operators is high (fixed-point casting needs to be realized by empirical operation), and the production efficiency is low. Compared with the prior art, the vacuum precision casting furnace adopting the automatic fixed-point casting device of the vacuum precision casting furnace has better product uniformity, better product quality, no operation experience requirement on operators and higher production efficiency.
