Description

Laser processing machine and laser processing method for diamond composite planar teeth Technical Field

[0001] This invention relates to the field of laser processing technology, and in particular to a laser processing machine and method for diamond composite planar teeth. Background Technology

[0002] Diamond composite planar teeth are made of two parts: diamond and cemented carbide. They are sintered under specific high temperature and high pressure conditions to form an ultra-hard composite material. They are commonly used in oil and gas geological drill bits and are suitable for drilling in medium to hard formations.

[0003] When machining the cutting end, i.e. the diamond part, of a diamond composite planar tooth, due to the high hardness of diamond, laser cutting machines are now commonly used for laser processing. However, the laser cutting head on existing laser cutting machines can only process at a single point. The focal point needs to be moved with the assistance of the mechanical axis on the machine tool to cut and fill the entire machining end face. However, the feed accuracy of the mechanical axis is not high, resulting in poor laser cutting and filling effect. This not only easily causes overlapping of processing paths and color difference, but also easily leads to over-cutting and filling, which does not meet the processing requirements.

[0004] It is evident that existing technologies still need improvement and enhancement. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a laser processing machine and laser processing method for diamond composite planar teeth, which aims to precisely cut and fill the cutting end to form diamond composite planar teeth, avoiding over-cutting and filling and color difference problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A laser processing machine and method for diamond composite planar teeth, comprising the following steps:

[0008] A1. The cylindrical blank is mounted on the laser processing machine. The A-axis turntable of the laser processing machine clamps the outer circle of the cylindrical blank through a fixture, so that the axis of the cylindrical blank extends laterally and the front end face of the cylindrical blank is perpendicular to the horizontal plane.

[0009] A2. The laser processing machine emits laser light through a scanning galvanometer module, and the laser light maintains a set angle with the front end face;

[0010] A3. Adjust the relative position of the laser focus and the cylindrical blank. The A-axis turntable drives the cylindrical blank to rotate at a fixed speed. The scanning galvanometer module and the machine tool mechanical axis control the movement of the laser focus to perform cutting processing on the outer circle of the cylindrical blank.

[0011] A4. Adjust the relative position of the laser focus and the cylindrical blank. The A-axis turntable drives the cylindrical blank to rotate at a fixed speed. The scanning galvanometer module and the machine tool mechanical axis control the movement of the laser focus to cut the front end face of the cylindrical blank to form a machined end face.

[0012] A5. The A-axis turntable stops rotating and fixes the cylindrical blank. The laser is focused on the machining end face. The galvanometer control card loads the galvanometer scanning path file. The mechanical axis and the scanning galvanometer module work together to complete the three-dimensional cutting and filling of the entire machining end face.

[0013] A6. Adjust the relative position of the laser focus and the cylindrical blank. The A-axis turntable drives the cylindrical blank to rotate at a fixed speed. The scanning galvanometer module and the machine tool mechanical axis control the movement of the laser focus. The laser processes the chamfer on the cylindrical blank.

[0014] A7. Obtain the diamond composite planar teeth and remove them from the laser processing machine.

[0015] As a further improvement to the above technical solution, step A5 is as follows: the position of the mechanical axis is not read in real time, the working speed of the scanning galvanometer module is preset, the scanning galvanometer module and the mechanical axis work separately, the laser is focused on the processing end face, the galvanometer control card loads the galvanometer scanning path file, and the scanning galvanometer module controls the laser to scan and fill the entire processing end face to form the first scanning filling layer.

[0016] As a further improvement to the above technical solution, the mechanical shaft drives the front end face of the cylindrical blank to the location of the laser focus, and the scanning galvanometer module controls the laser to scan and fill the second scanning filling layer; the mechanical shaft and the scanning galvanometer module repeat the above steps until the Nth end face to be filled is processed, where N is a natural number greater than 0.

[0017] As a further improvement to the above technical solution, step A5 specifically involves: reading the position of the mechanical axis in real time, loading the galvanometer scanning path file into the galvanometer control card, and having the mechanical axis and the scanning galvanometer module work simultaneously. The mechanical axis works according to the set scanning path, and the scanning galvanometer module works according to the galvanometer scanning path, cooperating with each other to fill the entire machining end face.

[0018] As a further improvement to the above technical solution, the galvanometer scanning path file specifically involves establishing a ZY rectangular coordinate system, with the origin of the ZY rectangular coordinate system being the center of the cylindrical blank. A circle is drawn with the origin as the center and the diameter of the cylindrical blank. Starting from the origin, multiple Z-axis coordinate points are generated along the positive and negative Z-axis directions with equal increments until the Z-axis coordinate points exceed the circle. At each Z-axis coordinate point, a straight line parallel to the Y-axis is drawn. The positions of the two boundary coordinate points where each straight line intersects the circle are calculated. All boundary coordinate points are summarized to obtain the cutting scanning boundary information. Then, based on the workpiece contour information, a galvanometer scanning path file corresponding to the Nth end face to be filled is generated. The galvanometer scanning path file is transmitted to the galvanometer control card.

[0019] As a further improvement to the above technical solution, in step A2, the laser maintains a set angle of 8°-10° with the front end face.

The control system includes a memory and at least one processor. The memory stores instructions. At least one processor calls the instructions in the memory to cause the laser processing machine for diamond composite planar teeth to execute the various steps of the laser processing method for diamond composite planar teeth.

Detailed Implementation

[0031] This invention provides a laser processing machine and method for diamond composite planar teeth. To make the objectives, technical solutions, and effects of this invention clearer and more explicit, the invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the scope of protection of the invention.

[0032] Please refer to Figures 1-4. This invention provides a laser processing method for diamond composite planar teeth 92, comprising the following steps:

[0033] A1. The cylindrical blank 91 is installed on the laser processing machine. The A-axis turntable 71 of the laser processing machine clamps the outer circle of the cylindrical blank 91 through the fixture 72, so that the axis of the cylindrical blank 91 extends laterally and the front end face of the cylindrical blank 91 is perpendicular to the horizontal plane.

[0034] A2. The laser processing machine emits a laser through the scanning galvanometer module 6, and the laser maintains a set angle with the front end face;

[0035] A3. Adjust the relative position of the laser focus and the cylindrical blank 91. The A-axis turntable 71 drives the cylindrical blank 91 to rotate at a fixed speed. The scanning galvanometer module 6 and the machine tool mechanical axis control the movement of the laser focus. Specifically, the laser focus moves to one side of the outer circle (i.e., the position indicated by F in Figure 3) to perform cutting on the outer circle of the cylindrical blank 91.

[0036] A4. Adjust the relative position of the laser focus and the cylindrical blank 91. The A-axis turntable 71 drives the cylindrical blank 91 to rotate at a fixed speed. The scanning galvanometer module 6 and the machine tool mechanical axis control the movement of the laser focus. Specifically, the laser focus moves to one side of the front end face (i.e., the position indicated by G in Figure 3) to cut the front end face of the cylindrical blank 91 to form a machined end face.

[0037] A5. The A-axis turntable 71 stops rotating and fixes the cylindrical blank 91. The laser is focused on the machining end face. The galvanometer control card loads the galvanometer scanning path file. The mechanical axis and the scanning galvanometer module 6 work together to complete the three-dimensional cutting and filling of the entire machining end face.

[0038] A6. Adjust the relative position of the laser focus and the cylindrical blank 91. The A-axis turntable 71 drives the cylindrical blank 91 to rotate at a fixed speed. The scanning galvanometer module 6 and the machine tool mechanical axis control the movement of the laser focus. The laser processes the chamfer on the cylindrical blank 91.

[0039] A7. Obtain diamond composite planar teeth 92 and remove them from the laser processing machine.

[0040] The laser processing method provided by this invention is specifically designed for processing diamond composite planar teeth 92. By coordinating the scanning galvanometer module 6 and the machine tool's mechanical axis, the possibility of overlapping processing paths is reduced, avoiding the resulting color difference problem. Using the scanning galvanometer module 6 to control the laser focus position allows for more precise control of the laser cutting path, thereby improving processing accuracy. This avoids the problems caused by low mechanical axis feed accuracy in traditional single-point processing methods, reduces the risk of over-cutting and filling, and ensures the cutting quality within the processing boundary.

[0041] In one embodiment, the position of the mechanical axis is not read in real time. The working speed of the scanning galvanometer module 6 is preset. The scanning galvanometer module 6 and the mechanical axis work separately. The laser is focused on the processing end face. The galvanometer control card loads the galvanometer scanning path file. The scanning galvanometer module 6 controls the laser to scan and fill the entire processing end face to form the first scanning filling layer. The mechanical axis drives the front end face of the cylindrical blank 91 to feed to the location of the laser focus. The scanning galvanometer module 6 controls the laser to scan and fill the second scanning filling layer. The mechanical axis and the scanning galvanometer module 6 repeat the above steps until the Nth end face to be filled is processed. N is a natural number greater than 0. That is, the processing of multiple scanning filling layers is repeated. The number of processing layers can be adjusted as needed to adapt to the processing requirements of diamond composite planar teeth 92 of different shapes and sizes.

[0042] By separating the scanning galvanometer module 6 from the mechanical axis, the design complexity of the control system is simplified, enabling faster system response and improving overall processing efficiency. Instead of real-time reading of the mechanical axis position, the operating speed of the scanning galvanometer module 6 is preset, reducing synchronization errors between systems and enhancing the stability of the processing. This separate operation design lowers the requirements for the control system, simplifies its design, and makes maintenance and debugging of the entire system more convenient. Furthermore, because the scanning galvanometer module 6 and the mechanical axis operate independently, the thickness of each scanning filler layer can be better controlled, thereby reducing potential defects during processing, such as color difference or over-cutting.

[0043] In another implementation, step A5 specifically involves: reading the position of the mechanical axis in real time, loading the galvanometer scanning path file into the galvanometer control card, and having the mechanical axis and the scanning galvanometer module 6 work simultaneously. The mechanical axis works according to the set scanning path, and the scanning galvanometer module 6 works according to the galvanometer scanning path, cooperating with each other to fill the entire machining end face.

[0044] Real-time reading of the mechanical axis position enables more efficient collaboration between the mechanical axis and the scanning galvanometer module 6, accelerating the entire processing speed. Furthermore, it broadens the processing range, allowing for flexible changes in the processing path to meet different needs and increasing the diversity of processing solutions. Synchronized operation of the mechanical axis and the scanning galvanometer module 6 better controls the laser focus position, avoiding color differences and over-cutting / filling issues caused by the low precision of a single mechanical axis feed.

[0045] The galvanometer scanning path file specifically establishes a ZY rectangular coordinate system, with the origin of the ZY rectangular coordinate system being the center of the cylindrical blank 91. A circle is drawn with the origin as the center and the diameter of the cylindrical blank 91. Starting from the origin, multiple Z-axis coordinate points are generated along both the positive and negative Z-axis directions with equal increments until the Z-axis coordinate points exceed the circle. At each Z-axis coordinate point, a straight line parallel to the Y-axis is drawn. The positions of the two boundary coordinate points where each line intersects the circle are calculated. All boundary coordinate points are summarized to obtain the cutting scanning boundary information. Then, based on the workpiece contour information, a galvanometer scanning path file corresponding to the Nth end face to be filled is generated. The galvanometer scanning path file is transferred to the galvanometer control card. By automating the calculation of boundary coordinate points, the generation process of the galvanometer scanning path file is simplified, making the operation simpler and faster.

[0046] Understandably, the smaller the increment of the segmentation interval, the more boundary coordinate points are obtained, resulting in a more circular cutting scan boundary and more accurate scanning filling of the boundary. This method can more accurately plan the galvanometer scanning path, ensuring that the galvanometer scanning path covers the entire machining end face while avoiding unnecessary repeated scanning or missed areas.

[0047] In step A2, the laser maintains a set angle of 8°-10° with the front end face. At an angle of 8°-10°, not only can the material removal rate be improved because the laser beam can more easily penetrate the material surface, thereby speeding up the processing, the laser beam can also interact better with the material surface, reducing the heat-affected zone and resulting in better surface and edge quality after processing.

[0048] As shown in Figure 2, the present invention also provides a laser processing machine for diamond composite planar teeth 92, including a bed 1, a gantry 2 mounted on the bed 1, an X-axis slide 3 located within the gantry 2 and slidably mounted on the bed 1, an X-axis drive mechanism for driving the X-axis slide 3 to move back and forth, and a control system. A Y-axis slide 4 is slidably mounted on the gantry 2, and a Y-axis drive mechanism is used to drive the Y-axis slide 4 to move left and right. A Z-axis slide 5 is slidably mounted on the Y-axis slide 4, and a Z-axis drive mechanism is used to drive the Z-axis slide 5 to move up and down. A scanning galvanometer module 6 is mounted on the Z-axis slide 5. An A-axis rotary table 71 and a fixture 72 mounted on the A-axis rotary table 71 are mounted on the X-axis slide 3. The control system includes a memory and at least one processor. The memory stores instructions. At least one processor calls the instructions in the memory to cause the laser processing machine for diamond composite planar teeth 92 to execute the various steps of the laser processing method for diamond composite planar teeth 92 as described above.

[0049] The X-axis extends horizontally, the Y-axis extends forward and backward, the Z-axis extends vertically, the C-axis extends vertically, and the A-axis extends horizontally, with the A-axis perpendicular to the C-axis.

[0050] During operation, the cylindrical blank 91 to be processed is gripped from the loading position 83 on the positioning fixture 82 and transferred to the clamp 72. With the precise movement of the X-axis slide 3, Y-axis slide 4 and Z-axis slide 5, the A-axis rotary table 71 drives the clamp 72 to rotate. That is, the X-axis, Y-axis, Z-axis and A-axis of the machine tool work together. Different parts of the diamond composite planar tooth 92 can be processed by the scanning galvanometer module 6, thereby achieving fine machining of multiple surfaces such as the outer circle, chamfer, and front end face to form the diamond composite planar tooth 92.

[0051] The laser processing machine for diamond composite planar teeth 92 provided by this invention, through multi-axis linkage and A-axis rotation, enables the equipment to perform all-round precision cutting and engraving of diamond composite planar teeth 92, which significantly improves processing accuracy and workpiece quality. It also has automated loading and unloading functions, greatly improving processing efficiency, reducing manual intervention, and is suitable for mass production.

[0052] In this embodiment, linear motors, which can achieve direct drive, have advantages such as lightweight structure, high transmission efficiency, safety and reliability, and long service life. The stator of the linear motor is fixed, and the mover of the linear motor drives the corresponding components to move. The X-axis drive mechanism, Y-axis drive mechanism, and Z-axis drive mechanism are all linear motors. The gantry 2 is equipped with a Y-axis guide rail, and the Y-axis slide saddle 4 is slidably connected to the Y-axis guide rail through a Y-axis slider. The bed 1 is equipped with an X-axis guide rail, and the X-axis slide table 3 is slidably connected to the X-axis guide rail through an X-axis slider. The Y-axis slide saddle 4 is equipped with a Z-axis guide rail, and the Z-axis slide saddle 5 is slidably connected to the Z-axis guide rail through a Z-axis slider. The Y-axis slide saddle 4, X-axis slide table 3, and Z-axis slide saddle 5 move smoothly and stably.

[0053] Preferably, the top of the Y-axis slide saddle 4 is provided with a top pull seat 41, and the Z-axis slide saddle 5 is provided with a balance cylinder 42. The cylinder body of the balance cylinder 42 is fixed on the Z-axis slide saddle 5, and the piston rod end is fixedly connected to the top pull seat 41. The X-axis drive mechanism, Y-axis drive mechanism, and Z-axis drive mechanism are all linear motors. By setting the balance cylinder 42 on the Z-axis slide saddle 5 and connecting it to the top pull seat 41 of the Y-axis slide saddle 4, the balance cylinder 42 can provide a corresponding reverse force when the Z-axis slide saddle 5 moves up and down, thereby reducing the load on the linear motor driving the Z-axis slide saddle 5 to move up and down, reducing the power requirement of the linear motor, and improving the service life of the linear motor.

[0054] In this embodiment, the clamp 72 is a three-jaw chuck. The three-jaw chuck applies clamping force to the workpiece through three evenly distributed jaws, providing a more uniform clamping force distribution and ensuring the workpiece remains stable during processing, reducing machining errors caused by workpiece movement. The three-jaw chuck has an automatic centering function, meaning it can automatically adjust the center of the workpiece to be aligned with the chuck's rotation axis. This feature is particularly important for machining diamond composite planar teeth 92, which requires high-precision positioning, helping to improve machining accuracy and consistency. Furthermore, the jaw spacing of the three-jaw chuck is adjustable, accommodating workpieces of different diameters, allowing the same machine to process diamond composite planar teeth 92 of various sizes, enhancing the machine's versatility and flexibility.

[0055] Specifically, the X-axis slide 3 is provided with a bracket 81 and a positioning fixture 82 placed on the bracket 81. The positioning fixture 82 is provided with multiple loading positions 83 for mounting workpieces. It can be understood that before processing, the loading positions 83 of the positioning fixture 82 are loaded with cylindrical blanks 91, and after the cylindrical blanks 91 are processed into diamond composite planar teeth 92, the loading positions 83 of the positioning fixture 82 are loaded with diamond composite planar teeth 92.
