Description

Technical Field

[0001] This utility model relates to the field of orientation correction tools, and in particular to a CNC engraving machine with an adjustable feeding function. Background Technology

[0002] In the field of CNC engraving machine processing, the accuracy of the workpiece feeding position directly determines the engraving quality. However, existing CNC engraving machines still have many technical defects in the feeding adjustment process.

[0003] Traditional equipment lacks an effective multi-component collaborative correction mechanism. Because it cannot accurately detect and adjust workpiece orientation deviations during the feeding process, the workpiece orientation judgment stage relies heavily on manual visual inspection. This not only requires highly experienced operators but also results in highly subjective and error-prone judgments, often necessitating repeated verification and significantly extending preparation time. In the deviation correction stage, existing equipment has a limited adjustment structure, often only capable of simple lateral or longitudinal translation adjustments, making it difficult to handle complex deviations such as angular offsets that may occur during workpiece placement. Furthermore, the poor compatibility between its drive and adjustment components prevents multi-level drive coordination for multi-angle, precise orientation calibration, leading to frequent workpiece offset problems. This, in turn, causes quality defects such as misaligned engraved patterns and out-of-tolerance dimensions, severely impacting processing accuracy. Therefore, these problems need to be addressed.

The first positioning platform 2, the second positioning platform 3, the guide rod 4, the sliding screw 5, and the first servo motor 6 constitute the sliding assembly. The sliding assembly is installed longitudinally above one side of the gantry frame 8. The guide rod 4 and the sliding screw 5 in the sliding assembly have lengths that match the longitudinal dimension of the gantry frame 8. The sliding screw 5 in the sliding assembly is threadedly connected to the moving platform 9. Limit rods are fixedly connected to the front and rear ends of the inner middle of the moving platform 9. A lifting screw is installed between the two limit rods. The lifting screw passes through the top surface of the moving platform 9 and is connected to the second servo motor through a coupling. The moving platform 9 facilitates the installation of various components of the limit lifting platform 10 through fixed connection and rotation. The material stacking adjustment assembly includes a threaded connection to the lifting screw. The lifting platform 10 facilitates the connection of the vision module 11 via external snap-fit ​​blocks or welding. The vision module 11 is fixedly connected to one side of the bottom surface of the lifting platform 10, which facilitates the adjustment of the object to be polished in conjunction with the subsequent sliding components, the first adjusting belt 20, and the second adjusting belt 26.

[0024] In this invention, an installation platform is provided on the top surface of the adsorption chamber 16 to accommodate the adsorption groove 17. A filter screen 18 is snapped onto the top surface of the adsorption groove 17. The filter screen 18 facilitates the filtration of waste debris generated during external grinding, preventing waste debris from falling into the adsorption chamber 16 and damaging the external negative pressure pump. The installation platform houses the suction nozzle 19, which provides suction to the adsorption groove 17. A first rotating rod is rotatably connected to the front and rear ends of one side of the first adjusting groove 13, and a second rotating rod is rotatably connected to the front and rear ends of the other side of the first adjusting groove 13. A first adjusting belt 20 is installed between the first and second rotating rods. An adjusting belt 20 facilitates the adjustment of the object to be ground placed on the top surface of the adjusting table 12; the distal ends of the two second rotating rods both penetrate the adjusting table 12, and the distal ends of the two second rotating rods are connected to stepper motors 21 via couplings. Placement platforms are installed at the front and rear ends of the other side of the adjusting table 12, and the stepper motors 21 are mounted on the placement platforms, providing driving force to the first adjusting belt 20; a first micro motor 25 is fixedly connected to the bottom surface of the second adjusting groove 14, facilitating the connection of the rotary table 29 via welding and driving the rotary table 29 to rotate; the output shaft of the first micro motor 25 is fixedly connected to... A rotary table 29, matching the inner diameter of the second adjustment groove 14, facilitates the rotation of internally connected components, thereby adjusting the workpiece to be polished. A drive groove is longitudinally formed in the center of the top surface of the rotary table 29. First rotating wheels 22 are rotatably connected to the front and rear ends above the drive groove. A second rotating wheel 23 is installed below and between the two first rotating wheels 22, with both sides of the second rotating wheel 23 rotatably connected within the drive groove. The first rotating wheels 22 and the second rotating wheel 23 facilitate the installation of a second adjustment belt 26. A connecting rod is installed on one side of the middle of the second rotating wheel 23, with the other end of the connecting rod passing through the rotary table 29. One end is connected to a second micro motor 24 via a coupling. The second micro motor 24 provides driving force to the second rotating wheel 23, thereby driving the second adjusting belt 26 to rotate. The second micro motor 24 is fixed to the outside of the rotating table 29 and placed inside the rotating groove 15. The second adjusting belt 26 is sleeved between the first rotating wheel 22 and the second rotating wheel 23. The second adjusting belt 26 is used to adjust the workpiece to be polished in conjunction with the first adjusting belt 20. A connecting platform connecting to the adsorption chamber 16 is opened at the middle of the front end of the adjusting table 12. An air supply pipe is connected to the middle of the front end of the connecting platform. The air supply pipe is clamped to the rear end of the sliding block 27.

[0025] Working principle: When using this utility model, the operator places the positioning frame 1 and the sliding assembly consisting of the first positioning platform 2, the second positioning platform 3, the guide rod 4, the sliding screw 5 and the first servo motor 6, as well as the sliding assembly, moving block 7, moving platform 9 and lifting platform 10 installed on the gantry frame 8, on the designed base surface. Then, the air supply pipe connected to the middle of the front end of the adjustment platform 12 is connected to the external negative pressure air pump, and then the equipment is powered on.

[0026] After the equipment is powered on, the first servo motor 6 is started, driving the sliding screw 5 to rotate, which in turn moves the moving block 7 and the adjusting table 12, facilitating the placement of the material to be ground by the operator. During the movement of the adjusting table 12, the sliding block 27 moves the air supply pipe along with it. The material to be ground is then placed on the top surface of the adjusting table 12, and the vision module 11 takes a picture. The data from the picture is compared with the orientation in the adapter controller connected to the vision module 11. If there is a deviation between the object to be ground and the program in the controller, the stepper motor 21 is started. The stepper motor 21 drives the first adjusting belt 20 in the first adjusting slot 13 to adjust the object to be ground. The vision module 11 then takes a second picture. If there is still a deviation between the object and the orientation in the controller, the first micro motor 25 installed on the bottom surface of the second adjusting slot 14 is started. The first micro motor 25 drives the rotary table 29 to rotate in the second adjusting slot 14. Since the second micro motor 24 is connected to the rotary table 29 through the second rotating wheel 23, and the first... The second micro motor 24 is placed inside the rotating slot 15, so the rotation of the rotary table 29 will drive the second micro motor 24 to rotate inside the rotating slot 15. When the rotary table 29 rotates to the expected position, the second micro motor 24 is started. The second micro motor 24 drives the second rotating wheel 23 to rotate. Since the first rotating wheel 22 and the second rotating wheel 23 are connected by a second adjusting belt 26, the rotation of the second rotating wheel 23 will drive the second adjusting belt 26 to rotate, thereby driving the workpiece to be polished to be adjusted. When it is adjusted to the appropriate position, the rotation is started. An external negative pressure air pump draws air out of the adsorption chamber 16, which is connected to the connecting groove 28, through the air supply pipe. This causes the suction nozzle 19 to generate negative pressure and adsorb the object to be polished. The object is then polished. Since the size of the object to be polished varies under different process requirements, some adsorption grooves 17 do not adsorb the object to be polished. Therefore, when polishing, the adsorption grooves 17 that do not adsorb the object to be polished will block the waste through the filter screen 18. When polishing the second product, the operator only needs to clean the filter screen 18.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
