Stagger up and down into 180 ° of distributions side.
Further, its modular construction, is integrated apparatus, and its location layout is according to respective functional characteristics and fine work(
It can realize and design.
Further, it is all that in the state of laser normal work, calculating is passed through by the program set that its function, which is realized,
What machine controller automatic synchronization was completed.
Further, its function is realized, is to detect cladding head actual temperature by touch sensor, data are passed in real time
Defeated to arrive computer control, computer control is judged according to the rated value of setting, instruction is assigned in real time, then refrigeration machine
Regulation is made according to instruction, so as to realize its function.
Further, its function is realized, is the powder density in ultrasonic wave powder density detector test chamber, by data
Computer control is real-time transmitted to, computer control calculates and is converted into powder feeding value automatically according to the formula of setting, with mark
After standard is worth relatively, judges, instruction is assigned in real time, then powder feeder makes regulation according to instruction, so as to realize its function.
Further, computer control can set new temperature rating, so as to disappear according to the change of environment temperature
Except environment temperature influences on cladding head.
Further, computer control can set new powder sending quantity mark according to different powder and actual surface quality
Quasi- value, so as to reach optimal powder feeding state.
The beneficial effects of the invention are as follows：
1st, the design invention of the laser melting coating head, effectively controls powder sending quantity, it is therefore prevented that accumulated powder, blocks cladding head, effectively improve
