Description
Technical field
The utility model relates to a kind of engraving machine portal frame mobile device, is specifically related to a kind of engraving machine gantry-travelling positioner.
Background technology
Mechanical sculpturing machine is the general machinery equipment of the industries such as a kind of carpenter's of being widely used in industry, advertising, mould industry, can carve the different materials such as woodwork plate, density board, acrylic board, PVC plate, according to the difference of engraving workpiece, engraving machine can be divided into planar engraving machine and cylinder engraving machine again.
Existing equipment is multidigit lead screw transmission in the walking process of gantry, and in its transmission process, stability is inadequate, and precision can not get controlling, and between work top and portal frame, in running, has vibrations, to whole mechanical control, cannot reach requirement.Therefore, for the mode of operation of the movement of engraving machine portal frame, location inaccuracy, engraving precision is not high.
Utility model content
The purpose of this utility model is the problem and shortage for above-mentioned existence, and a kind of engraving machine gantry-travelling positioner that can improve gantry-travelling stability and engraving precision is provided.
For achieving the above object, the technical scheme of taking is:
A kind of engraving machine gantry-travelling positioner, comprise operating platform and be arranged on the portal frame on operating platform, between described operating platform and portal frame, be provided with mobile positioning mechanism, described mobile positioning mechanism comprise be arranged on operating platform dual-side guide rail and tooth bar, be arranged on drive motors on portal frame and with the gear of drive motors interlock, described wheel and rack mates mutually, and described portal frame is provided with the guide pad that slides and locate with guide rail.
The both ends of described operating platform both sides are equipped with location collision block.
Described drive motors is two, and is separately positioned on the both sides of portal frame, and two drive motors are servo synchronous motor.
On described guide rail, offer wedge-shaped slot, described guide pad is provided with corresponding projection and wedge-shaped slot matches.
Adopt technique scheme, obtained beneficial effect is:
The utility model leads by rack-and-pinion transmission and wedge-shaped slot, greatly improved the stability of portal frame operation, on operating platform, be provided with positioner simultaneously, can be convenient to the raising with precision of controlling of whole equipment, this apparatus structure is simple, reasonable in design, control is convenient, not only the stability of the operation of support equipment, can also improve machining accuracy.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the left TV structure schematic diagram of Fig. 1.
Sequence number in figure: 1 is that operating platform, 2 is that portal frame, 3 is that guide rail, 4 is that tooth bar, 5 is that drive motors, 6 is that gear, 7 is to locate collision block.
