The invention discloses a laser working head with variable width of a cladding layer, belonging to the technical field of laser processing. The laser working head comprises a concave reflection mirror assembly, a convex reflection mirror assembly, a protection lens assembly and an adjusting assembly. A focusing system integrated with the working head comprises a convex reflection mirror and a concave reflection mirror; and because of the optimized optical design, the changes of the output focal length of the focusing system is realized by a manner of changing the distance between the two mirrors. Because of the installation of protection lens, partial thermal radiation light can be effectively prevented from entering a laser resonance cavity. For fiber lasers and semiconductor lasers, the stability of output power can be effectively ensured. During the laser cladding process, the working head can realize the real-time changes of the width of the cladding layer.

The invention discloses a rotational-torsion-varying double-shaft synchronous rotation shaft apparatus, which includes a first shaft core, a second shaft core, a rotational torsion varying mechanism, a first shaft torsion part, a second shaft torsion part, and a linking part. The rotational torsion varying mechanism includes a first elastomer and a second elastomer, a transmission connecting plate, and a first transmission body and a second transmission body; the first transmission body and the second transmission body fixedly sleeve respectively the first and the second shaft cores; the transmission connecting plate slidingly sleeves the first and the second shaft cores; the first and the second transmission bodies are jointed to the transmission connecting plate through torsion friction surfaces with positions having different circumferential rotational torsions; the first and the second elastomers are elastically pressed against one side of the transmission connecting plate; the linking part, the first and the second shaft torsion parts are arranged at the other side of the transmission connecting plate. The apparatus can achieve double-shaft synchronous rotation and achieve real-time varying torsion in the rotation of the shafts. The apparatus has more usage functions, such as light opening and heavy closing, heavy opening and heavy closing, heavy opening and light closing, and light opening and light closing.

The invention relates to the field of numerical control laser processing, and provides a control method and a control system of pulse width modulation (PWM) signals and a numerical control laser processing machining tool. The control method of the PWM signals comprises the following steps: acquiring machine tool motion information and PWM signal configuration information, wherein the machine tool motion information comprises zone bit which shows machine tool motion state and analog quantity which changes in proportion with machine tool motion speeds, judging the machine tool motion state according to the zone bit, if the machine tool is in a motion state, the PWM signals are generated according to the analog quantity and the PWM signal configuration information; and if the machine tool is in a static state, the PWM signals are generated according to the PWM signal configuration information. A computer numerical control (CNC) system is used for directly controlling the PWM signals to control a system to carry out change of pulse signal frequency and duty cycle, delay of pulse signals is shortened, lag caused by programmable logic controller (PLC) cycle operation time is avoided, and cutting effect and cutting accuracy are improved effectively.
