Abstract
The invention relates to a centrifugal casting machine. The centrifugal casting machine comprises a variable frequency motor which drives a main shaft to run through a belt pulley; one end of the main shaft is connected with a die and while the other end of the main shaft is connected with a counterweight plate; a speed regulation controller for regulating the running speed of the variable frequency motor is connected to the variable frequency motor. The counterweight plate has the advantages that 1) the running speed of the variable frequency motor is adjusted through the speed regulating controller, the continuous adjustment can be achieved, and thus the casting quality and the casting efficiency can be ensured; 2) a speed sensor is specifically arranged on the main shaft and sends a detected signal to the speed regulating controller to control the running speed of the variable frequency, in order to ensure the accuracy of speed regulation; the signal is directly picked up from the main shaft, so that error caused by the transmission system is minimized, the running speed of the motor can be accurately adjusted, and as a result, the casting quality can be further ensured; 3) the counterweight plate is detachable, and thus the flexible adjusting is achieved according to the actual condition.
Description
Technical field
The present invention relates to a kind of centrifugal casting machine, belong to placing installation technical field.
Background technology
Centrifugally to build, as the term suggests, be exactly centrifugal action processing work, drive main shaft to rotate by variable-frequency motor, need to adjust motor speed flexibly according to actual conditions in process; But existing adjustment mode is generally adjusted by manual type, is discontinuous, i.e. impact casting quality, again impact casting efficiency; Simultaneously while casting in order to balance, often need to configure balancing disk, but existing balancing disk its be monoblock type, weight can not adjust, can not carry out counterweight according to the actual conditions of casting, cause sometimes vibrating meeting than stronger, casting product out can not get effective guarantee, and easy mold damage, be badly in need of being improved.
Summary of the invention
The present invention is directed to above-mentioned defect, object be to provide a kind of structure simple, realize serialization electric machine speed regulation, thus ensure the centrifugal casting machine of casting quality.
The technical solution used in the present invention is for this reason: the present invention includes variable-frequency motor, variable-frequency motor drives spindle operation by belt pulley, main shaft one end connecting mold, the main shaft other end connects balancing disk, described variable-frequency motor is connected with the speed setting controller regulating variable-frequency motor rotating speed.
Described main shaft is provided with velocity sensor, and speed setting controller is provided with the receiver of inbound pacing sensor signal.
Described balancing disk is split type, is spliced by some pieces.
Described each balancing disk is pulled together by electromagnetic type suction.
Advantage of the present invention is: 1) the present invention adjusts the rotating speed of variable-frequency motor by speed setting controller, realizes serialization adjustment, thus ensures casting quality and casting efficiency; 2) the present invention is in order to ensure the accurate of speed governing further, spy arranges velocity sensor on main shaft, the signal detected is sent to speed setting controller to control variable-frequency motor rotating speed, because signal directly picks up from main shaft, therefore its error caused because of transmission system is less, thus more can adjust motor speed accurately, further ensure that casting quality; 3) balancing disk of the present invention is detachable, so just can realize adjustment flexibly according to actual conditions, moreover each balancing disk of the present invention is pulled together by the suction of electromagnetic type, connected mode is simple, easy to loading and unloading, the handling of each balancing disk are realized by power on/off, very easy to use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
1 be speed setting controller, 2 be variable-frequency motor in figure, 3 be belt pulley, 4 be main shaft, 5 be balancing disk, 6 be mould, 7 for velocity sensor.
Detailed description of the invention
The present invention includes variable-frequency motor 2, variable-frequency motor 2 drives main shaft 4 to operate by belt pulley 3, main shaft 4 one end connecting mold 6, and main shaft 4 other end connects balancing disk 5, described variable-frequency motor 2 is connected with the speed setting controller 1 regulating variable-frequency motor 2 rotating speed.
Described main shaft 4 is provided with velocity sensor 7, and speed setting controller 1 is provided with the receiver of inbound pacing sensor 7 signal.
Described balancing disk 5 is split type, is spliced by some pieces.
Described each balancing disk 5 is pulled together by electromagnetic type suction.
The course of work of the present invention is: velocity sensor 7 detects the rotating speed of main shaft 4, the signal detected is sent to speed setting controller 1, as it is inconsistent with the rotating speed preset, then control the adjustment that variable-frequency motor 2 carries out speed, until the rotating speed of main shaft 4 reaches default rotating speed.
Balancing disk 5 of the present invention is detachable in addition, is pulled together, carries out counterweight so flexibly preferably through electromagnetic force.
