Horizontal numerical control three-dimensional carving machine

Abstract

The invention discloses a horizontal numerical control three-dimensional carving machine which comprises a base, a portal frame, a workpiece clamping device, a transverse moving mechanism, a vertical moving mechanism and a carving tool frame. The workpiece clamping device comprises a fixed beam, a movable beam and a moving and fixing mechanism. A front-back moving mechanism is arranged between the workpiece clamping device and the base, and comprises two slide rails, slide blocks, a driving structure, slide rail waterproof covers and a movable base plate. The slide rails are fixedly arranged on the base. The driving structure is arranged in the middle. The slide blocks are arranged on the two sides, corresponding to the two slide rails, of the movable base plate respectively. The slide blocks are each of a crank structure. One end of each slide block slides on the corresponding slide rail, and the other end of each slide block is fixedly connected with the movable base plate. The slide water waterproof covers cover the two slide rails and cover the ends, correspondingly sliding on the slide rails, of the slide blocks respectively. The carving machine is high in structural weight capacity, stable in structure and smooth and stable in mechanical actions, and factors influencing carving accuracy and carving consistency can be reduced as much as possible.

Description

technical field [0001] The invention relates to the field of numerically controlled three-dimensional engraving machines, in particular to a numerically controlled three-dimensional engraving machine for horizontal clamping of engraved workpieces. Background technique [0002] The existing horizontal CNC three-dimensional engraving machine has a structure including a machine base, a gantry erected on the machine base, and a front and rear moving mechanism for enabling the gantry to move back and forth between the two bottom ends of the gantry and the machine base respectively. , the lateral movement mechanism erected on the frame, the up and down movement mechanism erected on the lateral movement mechanism, the engraving tool holder erected on the up and down movement mechanism, and the workpiece clamping device erected on the machine base and corresponding to the gantry, The workpiece clamping device includes a fixed beam and a movable beam that can move relative to the fix...

AI Technical Summary

Problems solved by technology

[0004] First of all, in terms of engraving accuracy, the two ends of the gantry of the existing engraving machine have forward and backward moving mechanisms respectively, and the gantry itself bears a heavy load. Once the gravity is unbalanced or the driving source of the two forward and backward moving mechanisms will produce The deviation cannot be synchronized, and it will have an immediate impact on the engraving accuracy. Even if the deviation is very small, the engraving effect will be subtly different. This is also true for the consistency of simultaneous engraving of multiple workpieces. Design requirements, not even an exquisite handicraft

[0005] Next, let’s talk about engraving efficiency. Each workpiece of the existing engraving machine corresponds to an engraving tool and all engraving is carried out by each engraving tool. In this way, the time required for engraving is longer, and the loss of the engraving tool is also relatively large, especially for The use of carving tools for fine carving is very wasteful, and the loss of carving tools may also affect the carving accuracy and carving effect

[0006] Let’s talk about the problem of engraving consistency. The mechanical design of synchronous engraving of multiple workpieces is a major step forward in improving the production efficiency of engraving handicrafts, but engraving consistency is the basic requirement for synchronous engraving of multiple workpieces. The structure of existing engraving machines exists There are many factors that will affect the consistency of engraving, so it is difficult to guarantee the consistency of engraving, such as the above-mentioned problem of the front and rear movement deviation of the gantry, the problem of unsmooth movement of each moving mechanism, etc.
