Description

Technical Field

[0001] This utility model relates to the field of machine tool equipment, and in particular to a multi-axis machining center. Background Technology

[0002] A CNC engraving and milling machine is a type of CNC machine tool. Generally, it's considered a CNC milling machine that uses small cutting tools, high-power, and high-speed spindle motors. While engraving machines excel at carving, they struggle with materials of high hardness. The emergence of the CNC engraving and milling machine fills this gap, as it can both engrave and mill, making it a highly efficient and precise CNC machine tool. The concept of the CNC engraving and milling machine was first proposed and implemented by Jiatie. It has a wide range of applications, including one-time roughing and finishing of precision mold cores, batch processing of mold copper electrodes, aluminum parts, shoe mold manufacturing, jig processing, and the watch and eyewear industry. With its high cost-effectiveness, fast processing speed, and good surface finish, the CNC engraving and milling machine is increasingly important in the machine tool processing industry, becoming an indispensable part of industrial automation. Existing engraving and milling machines typically include a movable platform that can move on a machine base. The movement of the movable platform is achieved by setting a slider at the lower end of the movable platform and forming a sliding connection between the slider and the slide rail on the machine base. Since the slider is usually directly fixed to the movable platform, the slider must be disassembled and installed together with the movable platform when it is disassembled and replaced, and the movable platform cannot be disassembled and installed separately, which causes inconvenience.

[0003] Therefore, a new technology needs to be developed to solve the above problems. Utility Model Content

The groove 95 extends in the front-rear direction and its front and rear ends respectively pass through the front and rear ends of the second sliding seat 90. The groove 95 is located inside the corresponding support protrusion 93 and is connected to the distance 108. In this way, the combination of the distance 108, the cavity 94 and the groove 95 can play a role in ventilation, so as to form a ventilation channel between the support platform 202 and the second sliding seat 90, which is more conducive to heat dissipation.

[0050] The outer wall of the supporting protrusion 93 is provided with a plurality of relief grooves 96, which are arranged sequentially at intervals of 108 along the front-back direction.

[0051] Both the upper and lower ends of the first sliding seat 103 are provided with stop blocks 109. The stop blocks 109 extend forward beyond the front side of the first sliding seat 103. The stop blocks 109 are used to limit the mounting seat 60. A limit sensor is provided on the stop blocks 109 so that the limit sensor and the stop blocks 109 together limit the mounting seat 60 in the vertical direction, thereby preventing the mounting seat 60 from moving beyond its travel range.

[0052] In summary, the key design feature of this utility model is that it mainly involves setting several first connecting holes at the upper end of the second sliding seat and several second connecting holes at the lower end of the support platform, so that the first connecting holes and the second connecting holes are connected by screws. This enables the support platform to be detachably installed, facilitating disassembly and replacement. It allows for the selective use of different support platforms to meet different processing needs, thereby satisfying more processing requirements and improving adaptability.
