The utility model solves the used technical scheme of its technical problem: a kind of laser head focus control comprises being used to connect the lift head and the bearing of laser head and driving lift head with respect to the lift head driving mechanism of bearing vertical lift be used for showing the graduated scale of relative position between the lift head of laser head and bearing.
Described lift head driving mechanism comprises gear and tooth bar, and the central shaft of gear is fixedly mounted on the bearing of laser head, and tooth bar is fixed on the lift head of laser head, and wheel and rack is meshed, and graduated scale is arranged on the bearing or lift head of laser head.During focusing, unscrew being arranged on tight fixed bolt on the bearing, that be used for fixing the lift head position, transmitting gear drives tooth bar and moves up and down, thereby make correspondingly lifting of lift head, by reading the graduated scale value, determine the position of lift head with respect to bearing, judge whether focal length adjusts to the right place, after focal length mixes up, tighten tight fixed bolt, fixedly lift head is focused and is finished.
Further, for ease of central gear axis is installed, the central shaft of described gear is fixedly mounted on the gear stand, and gear stand is fixedly mounted on the bearing.
For ease of driven wheel rotation, regulating the position of lift head easily, described gear face a handle is housed.
For making the laser head structure compactness, described tooth bar and lift head are structure as a whole.
For making focusing more convenient, described lift head driving mechanism comprises support, bolt, threaded block and jump ring, through hole is arranged on the support, bolt is located in the through hole, and screw is arranged on the threaded block, and bolt is threaded with the screw of threaded block, the polished rod section of bolt has the jump ring groove, jump ring is arranged in the jump ring groove, and the jump ring groove matches to the distance of the head of the bolt thickness with support, and graduated scale is fixedly mounted on support.
For ease of making, described graduated scale is for directly to be engraved on laser head bearing or the lift head outer surface.For ease of reading the position of lift head, it is more convenient to focus, and graduated scale is the digital display graduated scale.
The beneficial effects of the utility model are: this laser head focus control can be according to the thickness of required processing work, directly regulate the distance between lift head and the workbench, make that focusing is more convenient, processing work at different-thickness adds man-hour, only need to carry out corresponding distance and adjust, just can finish accurate focusing, thereby shorten the preparatory process time of processing greatly by lift head driving mechanism and graduated scale, improve production efficiency, saved production cost.
