Abstract
The utility model relates to production field of laser engraving machines, and particularly provides a pen type automatic focus control device of a laser engraving machine. Structurally, the pen type automatic focus control device of the laser engraving machine is mainly composed of a switch positioning shell body, a connecting shell body, a bottom end shell body, a magnetic switch, a magnet, a transmission core rod and a reset spring. The switch positioning shell body, the connecting shell body and the bottom end shell body are coaxially connected in a fixed mode from top to bottom, the magnetic switch is fixed at the axial core position of the switch positioning shell body, and the transmission core rod coaxially penetrates the connecting shell body and the bottom end shell body. The bottom end of the transmission core rod is exposed outside the lower portion of the bottom end shell body, and the magnet is fixed at the top end of the transmission core rod through a limiting connecting piece. The reset spring is connected on the middle-lower portion of the transmission core rod in a sleeved mode and arranged in bosses between the lower end of the connecting shell body and the lower end of the transmission core rod in an abutting mode, so the magnet and the magnetic switch are enabled to keep a proper distance. Compared with the prior art, the pen type automatic focus control device of the laser engraving machine has the advantages of being high in efficiency, stable in performance, low in failure rate, and the like.
Description
Technical field
The utility model relates to the laser engraving machine production field, and a kind of laser engraving machine pen type autofocus controlling apparatus specifically is provided.
Background technology
Laser engraving machine is with its higher carving efficiency, and the characteristics such as sculpture surface is smooth, mellow and full are widely used in various meticulous engravings field.
Because the focal position has a significant impact for shape and the degree of depth of the formed hole of carved workpiece groove, can the engraving machine autofocus navigate to the key that suitable gap has just become to affect the laser engraving quality with the engraving platform in high quality.
Usually utilize the photoelectricity approach switch to carry out auto focus control in the prior art, although application is comparatively extensive, exist to be difficult for adjusting, low, the easy distortion of efficient, the high deficiency of fault rate.
Summary of the invention
The utility model is for above-mentioned the deficiencies in the prior art, and the laser engraving machine pen type autofocus controlling apparatus of a kind of efficient height, stable performance, failure rate is low is provided.
The technical scheme that its technical problem that solves the utility model adopts is: laser engraving machine pen type autofocus controlling apparatus, mainly consisted of by switch positioning housing, connection housing, bottom housing, magnetic switch, magnet, transmission core bar and back-moving spring,
Switch positioning housing, connection housing and bottom housing be coaxial being fixedly connected with from top to bottom,
Described magnetic switch is fixed on switch positioning housing shaft core position,
Coaxial running through of described transmission core bar connects housing and bottom housing, and the bottom of transmission core bar exposes to the bottom hull outside,
Described magnet is fixed on transmission core bar top by limit connector,
Described back-moving spring is socketed in transmission core bar middle and lower part, and conflicts and to be arranged between the boss that connects housing lower end and transmission core bar lower end, makes magnet and magnetic switch keep suitable distance.
Described limit connector is preferably fixed hub, and the fixed hub lower end is fixed by socket on the top of transmission core bar, and magnet is fixed on the top of fixed hub.
The bottom of described transmission core bar is preferably the spherical crown shape.
Laser engraving machine pen type autofocus controlling apparatus of the present utility model is compared with existing technology, and has following outstanding beneficial effect:
(1) switch positioning housing, connection housing, bottom housing etc. all can adopt metal material processing to form, and are not yielding, failure rate is low, long service life;
(2) adopt magnetic switch to carry out auto focus control, be easy to regulate, control accurately, efficient is high.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model laser engraving machine pen type autofocus controlling apparatus.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as to restriction of the present utility model.
The below provides a most preferred embodiment:
Laser engraving machine pen type autofocus controlling apparatus mainly is made of switch positioning housing 1, connection housing 2, bottom housing 3, magnetic switch 4, magnet 5, transmission core bar 6 and back-moving spring 7.
The switch positioning housing 1 of metal material, connection housing 2 and bottom housing 3 be the coaxial form of a stroke or a combination of strokes shell that consists of focus control device that is fixedly connected with from top to bottom.
6 coaxial running through of transmission core bar connect housing 2 and bottom housing 3.The spherical crown shape bottom of transmission core bar 6 exposes to bottom housing 3 outsides, and the top is fixedly connected with magnet 5 by fixed hub 8.
Back-moving spring 7 conflicts that are socketed in transmission core bar 6 middle and lower parts are arranged between the boss that connects housing 2 lower ends and transmission core bar 6 lower ends, make magnet 5 and magnetic switch 4 keep suitable distance.
During use, autofocus controlling apparatus of the present utility model is fixed on the laser head place of laser engraving machine.During laser engraving machine work, control system is adjusted laser head and engraving platform spacing, and when the transmission core bar touched material for carving on it, transmission core bar band moving magnet magnetropism switch direction was close, and magnetic switch is closed, and focusing is finished the work.
Above-described embodiment, the utility model specific embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacing all should be included in the protection domain of the present utility model.
