Description

Vertical engraving machine
Technical Field
The utility model belongs to the technical field of machining equipment, a vertical engraver is related to.
Background
The engraving is a drilling and milling combined machining in principle, has wide application range, comprises a woodworking engraving machine, a laser engraving machine, an advertisement engraving machine, a jade engraving machine, a stone engraving machine, a cylindrical engraving machine and the like, has very wide application range, even replaces a manual engraving technology, and lays a foundation for the mass rapid production of products. The engraving machine comprises a vertical engraving machine and a horizontal engraving machine, wherein the vertical engraving machine mainly engraves cylindrical workpieces which are vertically arranged.
As in chinese patent [ application number: 201520260602.0 discloses a large vertical five-axis numerical control engraving device, which comprises a machine body, an engraving knife for engraving, an engraving knife rest for installing the engraving knife and a controller for controlling the operation of the large vertical five-axis numerical control engraving device, wherein the large vertical five-axis numerical control engraving device is provided with a left and right adjusting device for pushing the engraving knife rest to move left and right and an up and down adjusting device for pushing the engraving knife rest to move up and down. This carving tool of five numerical control engraving device of large-scale vertical can be from top to bottom and left and right sides direction adjusting position, still can rotate the carving tool to the platform that circles round can the back-and-forth movement, thereby conveniently carries out front and back position control to the handicraft, conveniently carves.
However, in the actual processing process, because the overall size of the columnar workpiece is large and the weight is heavy, when the rotary platform moves back and forth, the clamped workpiece is prone to shaking, so that the position after clamping and positioning is inaccurate, and the engraving precision is reduced.
The conventional technical means in the prior art generally avoids the problem that the carving precision of the workpiece is influenced because the workpiece is not firmly positioned when the rotary platform moves by strengthening the clamping and positioning of the workpiece; or directly design the platform of circling round for motionless to avoid the work piece to remove and lead to appearing the problem that the sculpture precision descends, for example chinese patent [ application number: 201410077893.X discloses a vertical multi-functional three-dimensional numerical control engraver of large-scale environmental protection, through the improvement to current large-scale engraver, increases the amount of feed of Z axle sculpture apart from the center pin, replaces the back-and-forth movement feed with the Y crossbeam, and Z feed stroke removes in the stand width, just so avoids above-mentioned platform of circling round to remove the problem that the sculpture precision descends that appears. However, on one hand, the design requires that the width of the rack of the horizontal longitudinal slide rail matched with the Y-shaped beam is enough, so that the whole gantry rack needs to be made very large, and the manufacturing cost of the machine is greatly increased; on the other hand, the width of the Y-shaped cross beam in the horizontal longitudinal direction is narrow, so that the area of the two ends of the Y-shaped cross beam in the horizontal longitudinal direction in sliding fit with the sliding rail is limited, and in addition, the vibration influence caused by the rotation of the cutter easily occurs, the unstable sliding condition of the horizontal longitudinal direction is easy to occur, and the improvement of the engraving precision is influenced; meanwhile, the Y-shaped cross beam is hung on the horizontal longitudinal slide rail, and the horizontal transverse length is long, so that the horizontal longitudinal movement is unstable due to the influence of vertical or longitudinal shearing force, and the engraving precision is influenced.
