Solid wax rod constant-pressure automatic wax coating device adopting torque motor

Abstract

The invention discloses a solid wax rod constant-pressure automatic wax coating device adopting a torque motor. The device comprises a torque motor driving module, a torque motor, a ball screw transmission module comprising a ball screw and a nut base in transmission with the torque motor, a solid wax rod clamping device fixed on the nut base, and a torque motor driver module connected with the torque motor and connected with an external control system; the torque motor driver module comprises a locked-rotor torque qualifying switch connected with the external control system; and when an output torque of the torque motor reaches a preset locked-rotor torque value, the locked-rotor torque qualifying switch is electrified, the torque motor is maintained in a locked-rotor state, and the ballscrew transmission module is stopped a feeding motion until the wax coating is finished. The wax coating device can synchronously compensate the solid wax rod and polishing wheel loss, realizes constant-pressure wax coating, can be mated with multiple types of polishing machines, and achieves a real automatic wax coating function.

Description

technical field [0001] The invention relates to a polishing and waxing system of a polishing machine, which belongs to the technical field of polishing equipment, in particular to a constant pressure automatic waxing device for solid wax strips using a torque motor. Background technique [0002] At present, the types of polishing wax used in polishing equipment are generally divided into liquid wax and solid wax. The use of liquid wax (that is, polishing agent, commonly known as water wax) requires a set of waxing equipment, which is a liquid wax barrel, a heating device, and a spraying device. There are certain limitations in practical applications: when the polishing wheel is worn out, the spray gun needs to be adjusted manually The angle fits the buffing wheel, otherwise the liquid wax will be sprayed onto areas other than the buffing wheel; it not only increases costs by wasting liquid wax, but it also contaminates equipment parts and is difficult to clean. Therefore, m...

The use of liquid wax (that is, polishing agent, commonly known as water wax) requires a set of waxing equipment, which is a liquid wax barrel, a heating device, and a spraying device. There are certain limitations in practical applications: when the polishing wheel is worn out, the spray gun needs to be adjusted manually Angled to match the buffing wheel, otherwise the liquid wax will be sprayed onto areas other than the buffing wheel; not only does it increase costs by wasting liquid wax, but it also contaminates equipment parts and is difficult to clean

However, the structure of the sliding table is complex and heavy, and the PLC in the complex integrated control system needs to communicate with the CNC system of the polishing machine to read the wear value of the polishing wheel for compensation value calculation, so it cannot be an independent waxing device. thus limiting its scope of application
