Description

Technical Field

[0001] The utility model relates to the technical field of high-gloss machines, in particular to an automatic tool-changing high-gloss machine. Background Art

[0002] The high gloss machine is named after the characteristics of the products it processes. Its appearance is similar to that of an engraving machine (or a precision engraving machine). The spindle uses a 100,000 RPM air-bearing spindle, which achieves a mirror-like effect when processing products, with no visible knife marks. High gloss machines are also known by many aliases, such as chamfering machines, bright edge machines, chamfering and high gloss machines, etc. High gloss machines have higher technical requirements and the requirements for accessories are much higher than those of ordinary engraving machines.

[0003] When using a traditional high gloss machine, it is inconvenient to perform automatic tool changing during the processing. Therefore, in the actual CNC processing process, manual tool changing is required. The manual tool changing process is likely to delay the processing time, thereby causing the processing efficiency of the high gloss machine to become low and reducing the processing effect. For this reason, the utility model proposes an automatic tool changing high gloss machine. Utility Model Content

[0027] Meanwhile when needing to carry out automatic tool changing work, the utility model is provided with to tool magazine 19 in the middle of portal 1, the tail end inside of tool magazine 19 is fixedly installed with three-stage motor 20, the output shaft of three-stage motor 20 is fixedly installed with three-stage ball screw 21, Y axis screw nut 22 is threadedly connected on three-stage ball screw 21, Y axis linear guide 23 is arranged on the two sides of Y axis screw nut 22, Y axis sliding block 24 is slidably connected on Y axis linear guide 23, Y axis sliding plate 25 is fixedly installed between two Y axis sliding blocks 24, Y axis sliding plate 25 is fixedly connected with Y axis screw nut 22, tool seat 26 is fixedly installed on the top of Y axis sliding plate 25, and a plurality of linearly distributed tools 27 are fixedly installed on tool seat 26;

[0028] This kind of structural design, when needing to change tool, three-stage motor 20 can work by being set, when three-stage motor 20 works, three-stage ball screw 21 is rotated by its output shaft, when three-stage ball screw 21 works, Y axis screw nut 22 threadedly connected thereon can move along Y axis direction, so that Y axis sliding plate 25 below is driven to extend by the Y axis screw nut 22 arranged, so that tool 27 on tool seat 26 can be moved forward and pushed out, and at this time, tool changing robot arranged outside can carry out automatic tool changing work;

[0029] In order to drive the tool to move left and right and ensure the normal machining displacement effect, a first-level ball screw 2 is rotatably installed on both ends of the outer surface of the front surface of the gantry 1 through a bearing seat. The external thread of the first-level ball screw 2 is connected to a first-level screw nut 4. The outer surface of the first-level screw nut 4 is fixedly installed with a Z-axis base plate 5. One end of the first-level ball screw 2 is fixedly connected to the output shaft of a first-level motor (not shown in the figure);

[0030] Therefore, when the first-stage motor is working, it will drive the first-stage ball screw 2 to rotate through the output shaft. When the first-stage ball screw 2 is rotating, the Z-axis base plate 5 on it will perform linear displacement left and right along the first-stage ball screw 2, thereby providing the necessary thread transmission conditions for the left and right displacement of the cutter head.

[0039] The utility model discloses a machining tool self-provided machining tool of machine tool has the use effect, and when being used actually, the automatic pushing of tool can be carried out through the Y-axis linear module, the automatic tool changing work can be completed through the external robot, and the automatic tool changing machining effect is achieved. Figure 6 When being used actually, the machining efficiency of high light machine can be improved, and the practicality is stronger.

[0040] When the primary motor works, the primary ball screw 2 is driven to rotate through the output shaft, when the primary ball screw 2 rotates, the Z-axis bottom plate 5 on it can linearly displace left and right along the primary ball screw 2, so that the Z-axis sliding plate 11 on the Z-axis bottom plate 5 can drive the tool head to linearly displace left and right integrally.

[0041] When the secondary motor 8 works, the secondary ball screw 6 is driven to rotate through the output shaft, when the secondary ball screw 6 rotates, the nut seat 7 screw-connected thereon can displace up and down (the up and down displacement of the nut seat 7 depends on the forward and reverse rotation of the secondary motor 8), so that the two groups of tool heads on the Z-axis sliding plate 11 can displace up and down through the up and down displacement of the nut seat 7, and the normal displacement use effect of the high light machine is ensured.

[0042] It is apparent for a person skilled in the art that the present application is not restricted to the details of the above exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary only, and not limiting, the scope of the present application being defined by the appended claims rather than the above description, and all changes coming within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
