technical field

The utility model belongs to the technical field of mechanical processing equipment, and relates to a vertical engraving machine.

Background technique

In terms of processing principle, engraving is a combination of drilling and milling. It has a wide range of applications, including woodworking engraving machines, laser engraving machines, advertising engraving machines, jade engraving machines, stone engraving machines, cylindrical engraving machines, etc. The engraving machine has a very wide range of applications. Extensive, even replacing hand-engraving techniques, laying the foundation for the rapid production of products in large quantities. The engraving machine is divided into a vertical engraving machine and a horizontal engraving machine, among which the vertical engraving machine is mainly used for engraving the columnar workpiece set vertically.

For example, Chinese patent [application number: 201520260602.0] discloses a large-scale vertical five-axis CNC engraving equipment including a machine body, a carving knife for carving, a carving knife holder for installing the carving knife, and a tool for controlling the large vertical The large-scale vertical five-axis CNC engraving equipment is provided with a left and right adjustment device for pushing the engraving tool holder to move left and right, and an up and down adjustment device for pushing the engraving tool holder to move up and down. The position of the engraving knife of this large-scale vertical five-axis CNC engraving equipment can be adjusted up and down and left and right, and the engraving knife can also be rotated, and the rotary platform can be moved back and forth, so as to facilitate the adjustment of the front and rear positions of the handicrafts and the engraving.

However, in the actual processing process, due to the large overall size and heavy weight of the cylindrical workpiece, when the above-mentioned rotary platform moves back and forth, the clamped workpiece is prone to shaking, resulting in inaccurate position after clamping and positioning. Causes the engraving precision to drop.

The conventional technical means in the prior art are generally to strengthen the clamping and positioning of the workpiece to avoid the problem that the workpiece is not positioned firmly when the rotary table moves, which will affect the engraving accuracy of the workpiece; or directly design the rotary table to not move. Avoid the problem of the reduction of engraving accuracy caused by the movement of the workpiece. For example, a large-scale environmental protection vertical multi-functional three-dimensional CNC engraving machine disclosed in Chinese Patent [Application No.: 201410077893.X], through the improvement of the existing large-scale engraving machine, increased The feed amount of Z axis engraving from the central axis, the Y beam is used instead of moving the knife forward and backward, and the Z infeed stroke moves within the width of the column, so as to avoid the problem of the decline of the engraving accuracy caused by the movement of the rotary platform. However, on the one hand, such a design requires that the frame width of the horizontal longitudinal slide rails used to cooperate with the Y beams should be sufficient, resulting in a large need for the entire gantry frame, which greatly increases the manufacturing cost of the machine; on the other hand, due to The width of the Y beam in the horizontal and longitudinal directions is very narrow, which results in a limited area for the two ends of the Y beam to slide with the slide rails in the horizontal and longitudinal directions. In addition, the vibration caused by the rotation of the tool is prone to unstable horizontal and vertical sliding in one dimension. At the same time, because the Y beam itself is suspended on the horizontal and vertical slide rails, and the horizontal and horizontal length is long, it is easy to be affected by the vertical or longitudinal shear force, resulting in the horizontal and vertical movement in this dimension. Unstable, this will also affect the engraving accuracy.

During processing, the workpiece is clamped and positioned on the mounting seat. The principle of how the vertical engraving machine can improve the engraving accuracy of the vertical workpiece is as follows: In this engraving machine, the three-dimensional moving frame and the base are divided into two parts, the base and the three-dimensional moving frame for installing the tool holder. The sliding connection is realized through the cooperation of the sliding rail and the sliding block, wherein the mounting seat is located at one end of the sliding rail, and the two are relatively fixed and located in the length direction of the sliding rail, so that the three-dimensional moving frame with the tool holder can move to the mounting seat. The position of the engraving machine is moved to meet the requirements of the tool head on the tool holder for engraving the workpiece on the mounting seat; from the above analysis, it can be seen that in this engraving machine, the mounting seat used for clamping large-sized and heavy workpieces does not move, but It is the whole three-dimensional moving frame that moves the tool holder for installing the cutter head to the position of the mounting seat, which avoids the problem of inaccurate clamping and positioning caused by the unstable movement of the workpiece and affects the engraving accuracy, and because the three-dimensional moving frame is The overall column-shaped and vertically arranged frame structure, the above-mentioned structural design not only makes the overall structure of the three-dimensional mobile frame stable, but also ensures that the three-dimensional mobile frame and the base have a sufficient matching area in the length direction of the slide rail when the three-dimensional mobile frame is slidably matched with the base. In combination, the bottom end of the three-dimensional moving frame is closer to the ground, so that the three-dimensional moving frame is very stable and reliable when it moves longitudinally on the base with the tool holder. Furthermore, the tool holder itself is light and not easily affected by the overall movement. The engraving accuracy of the engraving machine is greatly improved; at the same time, when two sliders are fixed on both sides of the bottom of the three-dimensional moving frame, that is, when the base and the three-dimensional moving frame are matched with four sliders, the three-dimensional moving frame itself The structural design, combined with the four-point rectangular arrangement design of the sliders on the bottom surface of the three-dimensional moving frame, ensures that the three-dimensional moving frame and the base have sufficient mating area while ensuring the balance of the three-dimensional moving frame, so that the three-dimensional moving frame can be moved.

Embodiment 2:

The technical solution in this embodiment is basically the same as that in Embodiment 1, the difference is that, in this embodiment, as shown in FIG. 3 , the mounting seat 3 is directly fixed on one end of the base 1a.

Embodiment three:

The technical solution in this embodiment is basically the same as the technical solution in Embodiment 1, the difference is that, in this embodiment, as shown in FIG.
