[0022] The structure is designed, the first level servo motor 3 and the second level servo motor 6 are arranged, the first level ball screw 4 and the second level ball screw 7 can be driven to rotate respectively, when the first level ball screw 4 and the second level ball screw 7 rotate respectively, the tool magazine auxiliary workbench 9 and the Y-axis workbench 10 screw-connected thereon can move linearly left and right along the screw rod, so that the normal screw transmission effect can be ensured;

[0023] In order to improve the displacement guiding property of the tool magazine auxiliary workbench 9 and the Y-axis workbench 10, the lower surfaces of the two ends of the tool magazine auxiliary workbench 9 are slidably connected with the tool magazine linear guide 5 respectively, and the lower surfaces of the two ends of the Y-axis workbench 10 are slidably connected with the two Y-axis guides 8 respectively.

[0024] The tool magazine linear guide 5 can be used as the linear displacement guiding track of the tool magazine auxiliary workbench 9, and the Y-axis guide 8 can be used as the linear displacement guiding track of the Y-axis workbench 10, so that the displacement guiding property of the two sliding seats can be effectively improved, the linear displacement characteristic can be ensured, the displacement accuracy can be improved, and good use effect is achieved.

[0025] In the embodiment, in order to improve the stability during the rotation transmission of the first level ball screw 4 and the second level ball screw 7, the one end of the first level ball screw 4 and the second level ball screw 7 is rotatably connected with a bearing seat, and the bearing seat is fixedly installed on the upper surface of the guiding groove of the marble bed 2.

[0026] In the embodiment, in order to ensure normal use, the upper surface of the tool magazine auxiliary workbench 9 is fixedly installed with a tool magazine bottom plate 11, the tool magazine bottom plate 11 can be installed with a tool for a precision engraving machine, and the upper surface of the Y-axis workbench 10 is fixedly installed with a marble workbench 12, and the marble workbench 12 can be used for installing a machining spindle.

[0027] Working principle: when the utility model is used, it is installed on the adaptive numerical control precision engraving machine,

[0028] The first level servo motor 3 and the second level servo motor 6 are arranged, the first level ball screw 4 and the second level ball screw 7 can be driven to rotate respectively, when the first level ball screw 4 and the second level ball screw 7 rotate respectively, the tool magazine auxiliary workbench 9 and the Y-axis workbench 10 screw-connected thereon can move linearly left and right along the screw rod, so that the normal screw transmission effect can be ensured;

[0029] When the tool magazine auxiliary workbench 9 and the Y-axis workbench 10 move, the tool magazine auxiliary workbench 9 and the Y-axis workbench 10 can drive the tool magazine bottom plate 11 and the marble workbench 12 to move linearly respectively, so that the double-guide linear movement effect of the tool magazine bottom plate 11 and the marble workbench 12 of the utility model can be ensured;

[0030] According to the above description, the double guide rail structure of the fine carving machine has the displacement characteristics of being independent in parts when performing linear displacement, can perform the driving operation of the two parts, and can effectively avoid the limitations caused by the unified driving of the traditional single guide rail.

[0031] The utility model discloses can according to actual use and processing condition, make the linear motion or relative motion of knife library bottom plate 11 and marble work platform 12 synchronously, namely mutually far away or mutually close, and the synchronous motion of differential speed, namely one right side fast motion, another right side slow motion, or the relative motion of differential speed, namely one right side slow movement, the other side left side fast motion,

[0032] Thus, through the independent structure of the double guide rail in actual use, the knife library bottom plate 11 and marble work platform 12 have the displacement characteristics of being flexible, effectively improve the flexibility of motion displacement, reduce the use limitation, so that the machining limitation of the fine carving machine can be effectively reduced, the use effect is improved, the structure is high in flexible degree of use, and the practicality is better.

[0033] It is to be noted that the moving direction and speed of the knife library bottom plate 11 and marble work platform 12 depend on the rotating direction and speed of the motor.

[0034] For example, when the knife library bottom plate 11 and marble work platform 12 perform synchronous linear motion, the rotating direction and speed of the first servo motor 3 and second servo motor 6 are the same, so that the knife library bottom plate 11 and marble work platform 12 perform synchronous linear displacement.

[0035] When the knife library bottom plate 11 and marble work platform 12 perform relative motion, the first servo motor 3 rotates forward, and the second servo motor 6 reverses, but the rotating speeds are the same, so that the knife library bottom plate 11 and marble work platform 12 perform relative motion at the same speed.

[0036] When the knife library bottom plate 11 and marble work platform 12 perform differential speed synchronous motion, the rotating directions of the first servo motor 3 and second servo motor 6 are the same, but the rotating speeds are different.

[0037] When the knife library bottom plate 11 and marble work platform 12 perform differential speed relative motion, the rotating directions and speeds of the first servo motor 3 and second servo motor 6 are different.

[0038] In this way, the rotating direction and speed of the motor are controlled, so that the knife library bottom plate 11 and marble work platform 12 can complete various linear displacement modes, the fine carving machine has good structure movement flexibility through the structure design of the double guide rail, and the machining limitation caused by unified driving is avoided.

[0039] It will be apparent to those skilled in the art that the application is not limited to the details of the above-exemplified embodiments and that the application can be implemented in other particular forms without departing from the spirit or essential characteristics of the application. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. No limitation is intended to the details of the drawing figures which are to be used only for illustration insofar as they do not pertain to the relevant claims.
