Description

Technical Field

[0001] The invention relates to the technical field of machine tool processing auxiliary devices, and in particular to a chip cleaning device suitable for precision machine tool processing. Background Art

[0002] CNC precision machine tools are automated machine tools equipped with program control systems. They can better solve the problems of complex, precise, small-batch, and multi-variety parts processing. They are flexible and high-efficiency automated machine tools. They represent the development direction of modern machine tool control technology and are typical mechatronics products. CNC machine tools will generate a large amount of debris during the processing process. If the debris remains in the machine tool for a long time, it will affect the CNC machine tool itself. Therefore, it is necessary to regularly remove chips from the CNC machine tool to prevent the accumulation of debris and affect the processing efficiency and precision of the machine tool.

[0003] Existing precision CNC machine tools generate a large amount of iron chips during the processing and production process.

[0014] Furthermore, the working method of the chip cleaning device suitable for precision machine tool processing includes the following steps:

[0015] Step 1, the cleaning rack is installed at the bottom of the precision machine tool processing area, and the lifting racks on the front and rear sides of the cleaning rack are controlled to move upward, so that the workpiece is processed between the two lifting racks on the front and rear sides. The debris generated during the processing of the workpiece splashes onto the guide rack 1 inside the two lifting racks. When the lifting and lowering control of the lifting rack is performed, the driving end of the micro-electric cylinder cooperates with the connecting rack to push the inside of the transmission gear 2 to engage with the surface of the rotating rod 1. At this time, the output shaft of the servo motor is used to control the rear crushing roller to rotate, and the driving gear 1 set at one end of the rear crushing roller rotates synchronously. At the same time, the driven gear 1 and the pulley 3, the pulley 2 and the lifting rack of the meshing transmission drive the rotating rod 1 to rotate synchronously, so that the transmission gear 2 also rotates, and the meshing transmission between the transmission gear 2 and the transmission tooth groove is used to control the lifting and lowering control of the lifting rack inside the sliding groove. After reaching the adjustment position, the self-locking member set inside the cleaning rack is used to self-lock the position of the lifting rack, and at the same time, the micro-electric cylinder is used to control the transmission gear 2 and the rotating rod 1 to release the limit connection;

[0016] Step 2: When processing the workpiece, use the connection blocks slidingly arranged on the two servo linear slides to drive the servo electric cylinder and the air blowing gun to move left and right inside the precision machine tool, and use the air blowing gun to blow the debris scattered on the surface of the workpiece, so that the debris generated during the processing of the workpiece is blown into the inside of 1;

[0017] Step 3: As the rotating rod 2 and the rotating rod 1 rotate synchronously, the surface of the transmission gear 1 and the surface of the transmission rack mesh and transmit, so the guide rack 1 inside the lifting frame and the guide rack 2 inside the cleaning frame rotate synchronously, and the guide rack 1 inside the lifting frame sends the blocked debris to the bottom, and then cooperates with the guide rack 2 to continue to send the collected debris to the bottom of the cleaning frame;

[0018] Step 4: The output shaft of the servo motor controls the rear crushing roller to rotate counterclockwise, and the driving gear 1 and the driving gear 2 that are meshed with each other drive the front crushing roller to rotate clockwise, so that the two crushing rollers inside the cleaning frame rotate relatively, and the two crushing rollers are used to crush the debris entering the cleaning frame;

[0019] Step 5. When the synchronous operation of the material blocking component and the cleaning component is controlled by the servo motor, the adsorption frame is controlled to rotate synchronously inside the screening frame through the pulley 4 set at one end of the front crushing roller, and the magnetism is generated by controlling the power supply of several electromagnet adsorption plates inside the adsorption frame to adsorb the metal materials in the crushed debris, and the non-metallic materials are discharged through the rear discharge hopper, and then the power supply of several electromagnet adsorption plates is turned off to remove the magnetism, and the metal materials adsorbed on the surface are discharged through the front discharge hopper.

[0020] The beneficial effects achieved by the present invention using the above structure are as follows:

[0021] 1. In the present invention, a cleaning rack is arranged at the bottom of the processing area of ​​the precision machine tool, and two material blocking assemblies on the front and rear sides of the cleaning rack are controlled to be lifted. When the precision machine tool is processing the workpiece, the material blocking assemblies arranged on the front and rear sides are used to block the splashing of debris. The debris generated during the processing of the workpiece falls into the interior of the cleaning rack, and the collected debris is sent to the bottom for crushing by the cleaning assemblies on the front and rear sides inside the cleaning rack, and then the metal debris and non-metal debris are coarsely screened by the screening assembly inside the screening rack, thereby reducing the waste of metal resources and realizing automatic cleaning of waste chips during the processing of the workpiece by the precision machine tool, thereby reducing the labor intensity of manually cleaning the debris. In addition, through the arrangement of the material blocking assembly and the cleaning assembly, the debris of the workpiece during the processing can be cleaned synchronously, without the need to shut down the precision machine tool and then clean the debris, thereby avoiding to a large extent the problem that the processing debris affects the processing quality of the workpiece, thereby improving the processing accuracy of the precision machine tool on the workpiece.

[0022] 2. In the present invention, the two material guide racks are controlled to rotate inside the two lifting racks to automatically remove the debris on the two material guide racks. At the same time, the connecting blocks slidingly arranged on the two servo linear slides are used to drive the servo electric cylinder and the air blowing spray gun to move left and right inside the precision machine tool. The air blowing spray gun is used to blow the debris scattered on the surface of the workpiece to ensure the surface cleanliness of the workpiece during the processing and reduce the influence of the debris on the processing accuracy of the workpiece.

[0023] 3. In the present invention, the collected debris is automatically crushed by two relatively rotating crushing rollers. The crushed debris enters the interior of the screening frame, and the screening component continues to perform coarse screening of metal and non-metal materials on the debris, thereby improving the recycling rate of metal resources.

[0024] 4. The present invention realizes the synchronized operation of the material blocking component, the cleaning component and the screening component by regulating a single motor, which improves the chip cleaning efficiency in the precision machine tool processing process while also simplifying the device structure and reducing the operating cost and equipment cost.
