Description

Technical Field

[0001] This utility model relates to the field of CNC engraving equipment technology, specifically a large engraving machine capable of dual-spindle processing. Background Technology

[0002] An engraving machine is a machine used to engrave various patterns on workpieces. Currently, most large engraving machines on the market are equipped with only one spindle. During mass production, the long spindle operating time results in low processing efficiency, and the single spindle limits the machine's processing capacity. Furthermore, most large engraving machines use aluminum profile frame structures, which have poor rigidity and are easily affected by vibration, leading to a decrease in processing accuracy. During processing, the lead screw faces the processing platform, making it easy for debris generated during processing to enter the lead screw, causing wear and affecting the machine's lifespan and maintenance costs. Therefore, existing technology suffers from low processing efficiency, insufficient machine strength, and high maintenance costs, necessitating a new engraving machine that can solve these problems. Utility Model Content

[0003] In response to the above situation and to overcome the current technical defects, this utility model provides a large-scale engraving machine with dual spindle processing.

Two sets of Y-axis are respectively provided on both sides of the processing platform. The two sets of Y-axis are driven by X-axis. The X-axis is driven by Z-axis. The Z-axis is driven by spindle. Spindle is used to drive engraving tool to engrave workpiece.

[0005] The device's Y-axis includes a Y-axis mounting bracket, a Y-axis closed-loop stepper motor, a Y-axis lead screw, and a Y-axis guide rail. The Y-axis mounting bracket is symmetrically mounted on both sides of the processing platform. The Y-axis closed-loop stepper motor is mounted on one side of the Y-axis mounting bracket. The Y-axis lead screw is rotatably mounted within the Y-axis mounting bracket. The Y-axis guide rail is mounted on the Y-axis mounting bracket and located above the Y-axis lead screw. The output shaft of the Y-axis closed-loop stepper motor is driven by the Y-axis lead screw via a Y-axis coupling. A Y-axis lead screw nut is threaded onto the Y-axis lead screw, and a... The component includes a Y-axis guide rail slider that slides on the Y-axis guide rail. The component is connected to the Y-axis guide rail slider. A Y-axis limit switch is installed at the bottom of the component. A Y-axis limit post adapted to the Y-axis limit switch is provided on one side of the bottom of the Y-axis mounting bracket. The Y-axis limit switch, in cooperation with the Y-axis limit post, provides an alarm to limit the Y-axis movement of the equipment. Y-axis buffer limit components are provided on both sides of the guide rail. The Y-axis buffer limit components prevent damage to the equipment caused by the component impact due to the failure of the Y-axis limit switch.

[0006] The device's X-axis includes an X-axis bracket mounted on the upper end of a connecting component, an X-axis closed-loop stepper motor, an X-axis lead screw, and an X-axis guide rail. The X-axis closed-loop stepper motor is mounted on one side of the X-axis bracket. The X-axis lead screw is rotatably mounted within the X-axis bracket. The X-axis closed-loop stepper motor is driven by the X-axis lead screw via an X-axis coupling. An X-axis lead screw nut is threaded onto the X-axis lead screw nut, and a connecting component is mounted on the X-axis lead screw nut. The X-axis guide rail is mounted on the upper and lower ends of one side of the X-axis bracket.

The X-axis limit switches limit the X-axis movement of the device by cooperating with the X-axis limit posts. Anti-collision blocks are also provided on both sides of the X-axis bracket to prevent damage to the device from impacts caused by malfunctioning X-axis limit switches.

[0007] The device's Z-axis includes a Z-axis mounting bracket, a Z-axis closed-loop stepper motor, and a Z-axis lead screw. The Z-axis mounting bracket is mounted on a connector, the Z-axis closed-loop stepper motor is mounted on the Z-axis mounting bracket, and the Z-axis lead screw is rotatably mounted within the Z-axis mounting bracket. The Z-axis closed-loop stepper motor drives the Z-axis lead screw to rotate via a Z-axis coupling. A lead screw nut is threaded onto the lead screw, and a spindle connector is mounted on the lead screw nut. Z-axis guide rails are symmetrically arranged on both sides inside the Z-axis mounting bracket, and Z-axis guide rail sliders slide on the Z-axis guide rails. The Z-axis guide rail sliders are connected to the spindle connector. A Z-axis limit switch is installed on one side of the spindle connector, and Z-axis limit posts are symmetrically arranged at the top and bottom ends on one side of the Z-axis mounting bracket.
