Description

Technical Field

[0001] This invention relates to the field of drilling and milling machines, and in particular to a CNC drilling and milling machine capable of side and front machining and its machining steps. Background Technology

[0002] With the development of technology, wood processing centers are increasingly used in the wood processing field. Traditional wooden door processing generally uses a combination of equipment such as hinge machines, lock-hole machines, door-making machines, squaring machines, and drilling machines. The technical characteristics of drilling are: the hole diameter is not large and the tolerance requirements are not high, which can be processed by drilling machines or hand drills. However, the technical characteristics of milling are: the workpiece surface has requirements, the hole diameter is larger, and it cannot be clamped on a lathe. It is processed by milling machines. Based on the technical characteristics of drilling and milling, once a workpiece has both drilling and milling processing requirements, it is necessary to drill and mill the workpiece separately on drilling machines and milling machines in steps. Although the processing requirements are met, this processing method requires the workpiece to be transferred to milling machines and drilling machines for separate processing, which results in low processing efficiency. At the same time, the workpiece itself may be damaged during the workpiece handling process, which leads to a decrease in processing quality.

[0003] Later, a wood milling center appeared on the market. It placed the workpiece on the worktable and moved the top milling mechanism and the side milling mechanism to the corresponding processing position of the workpiece through their respective displacement devices to perform top milling and side milling operations. However, its structural design was poor. The top milling mechanism and the side milling mechanism were set separately on both sides of the worktable, so the top surface processing and the side processing of the workpiece were performed separately. The workpiece processing time was long, which reduced the processing efficiency of the workpiece. It was not practical and had a limited range of applications.

[0004] Therefore, it is necessary to research a new technical solution to address the above problems. Summary of the Invention

[0005] In view of this, the present invention addresses the deficiencies of the existing technology, and its main objective is to provide a CNC drilling and milling machine capable of side and front machining and its machining steps.

The control mechanism 40 is connected to the front drilling and milling assembly 23, the side drilling and milling assembly 34, the first displacement device 25, the second displacement device 26, the first lifting device 27, and the second lifting device 33. In this way, through the design of the machine head, the pressing mechanism presses and positions the workpiece, and with the control of the corresponding displacement mechanism, the front drilling and milling assembly and the side drilling and milling assembly are moved to the processing position of the workpiece, so as to realize the front and side processing of the workpiece at the same time, reducing the processing time of the workpiece, thereby improving the processing efficiency of the product. The structure design is ingenious and reasonable, meets the user's needs, is highly practical, and has a wide range of applications.

[0059] In this embodiment, two side milling components 24 are provided, one on the left and one on the right of the mounting plate. The mounting plate includes a front side plate 271 and side plate portions 272 on both sides of the front side plate.

It also includes two sets of oblique machining components 28, which are provided on the two side plate portions 272 of the mounting plate. The front milling component 23 is located between the two sets of oblique machining components 28. One set of oblique machining components 28 is used for oblique downward machining from front to back, and the other set is used for oblique downward machining from back to front. Thus, the provision of two side milling components improves the efficiency of workpiece side machining. Simultaneously, the oblique machining components enable oblique machining of the workpiece side, meeting the side machining needs of different workpieces and demonstrating strong practicality.

[0060] Furthermore, the pressing mechanism 30 is connected to a third displacement device 34, which controls the pressing mechanism to reciprocate along the Y-axis on the machine body.

Thus, the movable setting of the pressing mechanism facilitates the pressing and positioning of workpieces of different specifications on the worktable, ensuring the quality stability of the front and side processing of the workpieces.

[0061] Furthermore, the workbench 11 is provided with a first station 111 and a second station 112 arranged sequentially along the X-axis. Several pressure plates 32 and a second lifting device 33 are provided and spaced along the X-axis on the mounting frame 31. A portion of the pressure plates 32 are located above the first station 111, and another portion are located above the second station 112. Preferably, the machine body 10 is provided with a tool magazine 1 for automatic tool changing in conjunction with the front drilling and milling assembly 23 and the side drilling and milling assembly 24. 4. Tool setter 15: The tool magazine 14 and tool setter 15 are located on the side of the worktable 11. Thus, the setting of the first station and the second station enables dual-station machining of the worktable, further reducing the machining time of the workpiece and improving the production efficiency of the product. At the same time, the tool magazine and tool setter read the tool numbers of the front drilling and milling assembly and the side drilling and milling assembly according to the operation of the machining program and replace the corresponding tool numbers on the front drilling and milling assembly and the side drilling and milling assembly to meet the requirements of front and side machining of the workpiece.

[0062] Furthermore, the machine head 20 is equipped with a thickness detection mechanism 29 for detecting the thickness of the workpiece. The thickness detection mechanism 29 is located on the side plate of the mounting plate and next to the front drilling and milling assembly 23. The thickness detection mechanism 29 includes a positioning block 291, a detection switch 292, and a third lifting device 293.

The detection switch 292 and the third lifting device 293 are respectively connected to the control mechanism 40. In this way, the thickness detection mechanism can detect the thickness of the workpiece and screen out unqualified workpieces, ensuring the pass rate of subsequent products, reducing rework or scrap, and improving usability.

[0063] A dust collection mechanism 16 is also provided. The dust collection mechanism 16 is disposed on the body 10 and located on the rear side of the worktable 11. The machine head 20 is located above the dust collection mechanism 16. The dust collection mechanism 16 includes a dust collection hood 161 and a fourth displacement device 162 for controlling the dust collection hood to move back and forth along the X-axis direction.

[0064] A CNC drilling and milling machine operating procedure includes the following steps:

[0065] Step 1: First, place the workpiece on the worktable;

[0067] Step 3: Start the machine head, run the machining program through the control mechanism and read the tool numbers of the front drilling and milling assembly and the side drilling and milling assembly, and then perform tool changing and tool setting operations;

[0068] Step 4: Use the control mechanism to start the thickness detection mechanism. The third lifting device controls the positioning block to move toward the workpiece so that the detection switch contacts the workpiece. After the detection switch contacts the workpiece, it will feed back the information and obtain the workpiece thickness measurement value.

[0069] Step 5: The front drilling and milling assembly and the side drilling and milling assembly are moved to the processing position under the control of the first displacement device, the second displacement device and the first lifting device, and drilling and milling operations are performed on the front and side of the workpiece respectively;

[0070] Step Six: After processing is complete, the machine head moves away from the workpiece, the pressure plate rises, and the workpiece is removed.

[0071] The key design feature of this invention is that it uses a pressure mechanism to hold and position the workpiece through the design of the machine head, and then moves the front drilling and milling components and the side drilling and milling components to the processing position of the workpiece in conjunction with the control of the corresponding displacement mechanism. This allows for simultaneous front and side processing of the workpiece, reducing the processing time of the workpiece and thus improving the processing efficiency of the product. The structure is ingenious and reasonable, meets the user's needs, is highly practical, and has a wide range of applications.

[0072] Secondly, the setting of two side drilling and milling components improves the efficiency of workpiece side processing. At the same time, the setting of the oblique processing component enables oblique processing of the workpiece side, meeting the side processing needs of different workpieces and is highly practical. Furthermore, the movable setting of the clamping mechanism facilitates the clamping and positioning of workpieces of different specifications on the worktable, ensuring the quality stability of the front and side processing of the workpiece.

[0073] Furthermore, the setup of the first and second workstations enables dual-station machining on the worktable, further reducing workpiece machining time and improving production efficiency. Simultaneously, the tool magazine and tool setter read the tool numbers of the front and side drilling and milling components according to the machining program and replace them accordingly to meet the requirements of front and side machining.
