Embodiment 1

[0020] Example 1: see figure 1 , 2 As shown, the gravity casting automatic pouring system includes a gravity casting machine 1, a pouring robot 2 and a pouring system control host 3, a mold 12 to be poured is fixed on the mold clamp 11 of the gravity casting machine 1, the pouring robot 2 has a robot host 21, and the robot The numerical control system of the host 21 or the program in the pouring system host 3 sends out command signals to control the motor-driven pouring arm 22 to move in three dimensions, and the pouring robot 2 is fixed on the foundation, on the foundation in front of the gravity casting machine 1 or on the gravity casting machine 1 There is a three-dimensional coordinate origin A, and the three-dimensional coordinate values ​​X1, Y1, Z1 between the three-dimensional coordinate origin A and the pouring robot’s own reference point B are input into the numerical control program in the robot host 21 or the program in the pouring system host 3, and the three-dim...

Embodiment 2

[0027] Example 2, see image 3 As shown, when the mold sprue center 121 is on the same straight line as the robot's own reference point in the three-dimensional coordinates centered on the three-dimensional coordinate origin A, the coordinate value X2 between the three-dimensional coordinate origin A and the mold sprue center 121, The coordinate value Z2 on the Z axis among Y2 and Z2 is 0.

[0028] Working principle: The pouring robot 2 itself has its own robot host 21 and the numerical control program in the robot host 21. At the same time, the pouring robot 2 can accept the instructions of the pouring system host 3 and execute the instructions of the host 3. In the prior art, the user adjusts the ladle mouth to the expected pouring point by operating the robot, such as moving the position of the pouring arm 22 of the robot, and inputting the value of the motor control command on the robot host. This speed is very slow, and adjustment It is very inconvenient. The input value...

Abstract

The invention relates to a gravity casting automatic pouring system. In the invention, three-dimensional coordinate values between a three-dimensional coordinate original point and a self datum point of a pouring robot and three-dimensional coordinate values between the three-dimensional coordinate original point and the center of a die pouring port are input into a robot host or a pouring systemhost and calculated and analyzed by a numerical control program in the robot host or a program in the system host, and then a command signal is sent out to control a motor to drive a pouring arm to do three-dimensional motions. A method for quickly searching a pouring point of the gravity casting automatic pouring system comprises the following steps of: measuring the three-dimensional coordinatevalues between the three-dimensional coordinate original point and the self datum point of the pouring robot and three-dimensional coordinate values between the three-dimensional coordinate original point and the center of the die pouring port and inputting the values into the robot host; calculating and analyzing the values by the numerical control program in the robot host or the program in thesystem host; and then sending out the command signal to accurately finding out the center of the pouring port. The invention greatly prolongs the robot adjustment time after die replacement and has extremely low requirement on a user who does not need to have skills to operate the robot, thus the operation is convenient and visual.

Description

Technical field: [0001] The invention relates to the technical field of gravity casting, in particular to an automatic pouring system of a gravity casting machine and a method for a robot in the system to quickly find a pouring point. Background technique: [0002] At present, in the automatic pouring system applied to gravity casting, when the gate changes with the change of the mold, every time the mold of the casting machine is replaced, the pouring point needs to be readjusted due to the change of the gate position. The user needs to operate the robot to adjust the ladle mouth to the expected pouring point and save it. This requires the user to be able to operate the robot proficiently, which requires high skills and takes a long time to adjust. The entire adjustment process must be operated very carefully to ensure the accuracy of the pouring point. Invention content: [0003] The purpose of the present invention is to address the deficiencies of the prior art, and p...
