Description

Technical Field

[0001] The present invention relates to the technical field of laser processing, and in particular to a laser processing machine and a laser processing method for diamond composite plane teeth. Background Art

[0002] Diamond composite flat teeth are composed of diamond and cemented carbide, and are super-hard composite materials sintered under specific high temperature and high pressure conditions. They are commonly used in petroleum geological drill bits and are suitable for drilling in medium-soft to hard formations.

[0003] When processing the cutting end of the diamond composite plane tooth, that is, the diamond part, due to the high hardness of the diamond material, laser cutting machines are now tended to be used for laser processing. However, the laser cutting head on the existing laser cutting machine can only process a single point. The focus must be moved with the assistance of the movement of the mechanical axis on the machine tool to perform cutting and filling processing on the entire processing end face. However, the feed accuracy of the mechanical axis is not high, resulting in poor laser cutting and filling effects. Not only is it easy to cause overlapping of processing paths to cause color aberration, it is also very easy to over-cut and fill, which does not meet the processing requirements.

[0004] It can be seen that the existing technology still needs to be improved and enhanced. Summary of the invention

[0016] As a further improvement of the above technical solution, the galvanometer scanning path file specifically establishes a ZY rectangular coordinate system, the coordinate origin of the ZY rectangular coordinate system is the center of the cylindrical blank, and a circle is drawn with the coordinate origin as the center and the diameter value of the cylindrical blank.

DETAILED DESCRIPTION

[0028] The present invention provides a laser processing machine and a laser processing method for a diamond composite plane tooth. In order to make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the scope of protection of the present invention.

[0029] See also Figure 1-Figure 4 The present invention provides a laser processing method for a diamond composite flat tooth 92, comprising the following steps:

[0030] A1. The cylindrical blank 91 is mounted on the laser processing machine, and the A-axis turntable 71 of the laser processing machine clamps the outer circle of the cylindrical blank 91 through the clamp 72, so that the axis of the cylindrical blank 91 extends laterally, and the front end surface of the cylindrical blank 91 is perpendicular to the horizontal plane;

[0031] A2. The laser processing machine emits laser through the scanning galvanometer module 6, and the laser maintains a set angle with the front end surface; A3. The relative position of the laser focus and the cylindrical blank 91 is adjusted, and 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, and the laser focus is specifically moved to one side of the outer circle (i.e. Figure 3 At the position indicated by F in the figure, the outer circle of the cylindrical blank 91 is cut;

[0032] 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 surface (i.e. Figure 3At the position indicated by G in the figure, the front end face of the cylindrical blank 91 is cut to form a machined end face;

[0033] A5. The A-axis turntable 71 stops rotating to fix the cylindrical blank 91, the laser is focused on the processing end surface, the galvanometer control card loads the galvanometer scanning path file, and the mechanical axis and the scanning galvanometer module 6 work together to complete the three-dimensional cutting and filling of the entire processing end surface;

[0034] 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 of the cylindrical blank 91.

[0035] A7. Obtain the diamond composite face tooth 92 and remove it from the laser processing machine.

[0036] The laser processing method provided by the present invention is specifically used for the processing of diamond composite plane teeth 92. The possibility of overlapping processing paths is reduced through the coordinated work of the scanning galvanometer module 6 and the mechanical axis of the machine tool, thereby avoiding the chromatic aberration problem caused thereby. Using the scanning galvanometer module 6 to control the position of the laser focus can more accurately control the laser cutting path, thereby improving the processing accuracy, avoiding the problems caused by the low feeding accuracy of the mechanical axis in the traditional single-point processing method, and reducing the risk of over-cutting and filling, ensuring the cutting quality within the processing boundary.

[0037] 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, and the scanning galvanometer module 6 controls the laser scanning to 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 be fed to the laser focus, and the scanning galvanometer module 6 controls the laser scanning to 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, and the number of processing layers can be adjusted as needed to meet the processing requirements of diamond composite planar teeth 92 of different shapes and sizes.

[0038] By making the scanning galvanometer module 6 and the mechanical axis work separately, the design complexity of the control system is simplified, so that the system can respond faster and improve the overall efficiency of the processing. Instead of reading the position of the mechanical axis in real time, the working speed of the scanning galvanometer module 6 is preset. This approach reduces the synchronization error between systems and enhances the stability of the processing process. The separate working design reduces the requirements of the control system, simplifies the design of the control system, and makes the maintenance and debugging of the entire system more convenient. In addition, since the scanning galvanometer module 6 and the mechanical axis work independently, the thickness of each scanning filling layer can be better controlled, thereby reducing defects that may occur during the processing process, such as color difference or over-cutting.

[0039] In another embodiment, step A5 is specifically as follows: the position of the mechanical axis is read in real time, the galvanometer control card loads the galvanometer scanning path file, the mechanical axis and the scanning galvanometer module 6 work simultaneously, the mechanical axis works according to the set scanning path, the scanning galvanometer module 6 works according to the galvanometer scanning path, and they cooperate with each other to fill and process the entire processing end surface.

[0040] The real-time reading of the position of the mechanical axis enables the mechanical axis and the scanning galvanometer module 6 to work together more efficiently, speeding up the entire processing process; on the other hand, the processing range is wider, and the processing path can be flexibly changed according to different processing requirements, increasing the diversity of processing solutions. The synchronous operation of the mechanical axis and the scanning galvanometer module 6 can better control the position of the laser focus, avoiding the color difference and over-cutting filling problems caused by the low single feeding accuracy of the mechanical axis.

[0041] The galvanometer scanning path file specifically establishes a ZY rectangular coordinate system, the coordinate origin of the ZY rectangular coordinate system is the center of the cylindrical blank 91, and a circle is drawn with the coordinate origin as the center and the diameter value of the cylindrical blank 91, and multiple Z-axis coordinate points on the Z-axis are formed incrementally with equal segmentation intervals along the positive direction and negative direction of the Z-axis from the coordinate origin, until the Z-axis coordinate point exceeds the circle, the incremental generation of the Z-axis coordinate point is stopped, and a straight line parallel to the Y-axis is drawn at each Z-axis coordinate point, and the positions of the two boundary coordinate points where each straight line intersects with the circle are calculated, and all boundary coordinate points are summarized to obtain the cutting scanning boundary information, and then a galvanometer scanning path file corresponding to the Nth end face to be filled is generated according to the workpiece contour information, and the galvanometer scanning path file is transmitted to the galvanometer control card. By automatically calculating the boundary coordinate points, the generation process of the galvanometer scanning path file is simplified, making the operation simpler and faster.

[0042] It is understandable that when the segmentation interval increment is smaller, the number of boundary coordinate points obtained will be greater, so the cutting scanning boundary will be more circular, making the scanning filling boundary more accurate. This method can more accurately plan the galvanometer scanning path, ensuring that the galvanometer scanning path covers the entire processing end surface while avoiding unnecessary repeated scanning or missing areas.

[0043] In step A2, the laser maintains a set angle of 8°-10° with the front face. At an inclination 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 speed, but the laser beam can also better interact with the material surface, reduce the heat-affected zone, and make the surface quality and edge quality after processing better.

[0044] See Figure 2 As shown, the present invention also provides a laser processing machine for diamond composite planar teeth 92, comprising a bed 1, a gantry 2 arranged on the bed 1, an X-axis slide 3 located in the gantry 2 and slidably arranged on the bed 1, an X-axis drive mechanism for driving the X-axis slide 3 to move forward and backward, and a control system, the gantry 2 is slidably provided with a Y-axis saddle 4, a Y-axis drive mechanism for driving the Y-axis saddle 4 to move left and right, the Y-axis saddle 4 is slidably provided with a Z-axis saddle 5, and a Z-axis drive mechanism for driving the Z-axis saddle 5 to move up and down, the Z-axis saddle 5 is provided with a scanning galvanometer module 6, the X-axis slide 3 is provided with an A-axis turntable 71 and a fixture 72 installed on the A-axis turntable 71; the control system comprises a memory and at least one processor, the memory stores instructions; at least one of the processors calls the instructions in the memory so that the laser processing machine for the diamond composite planar teeth 92 performs each step of the laser processing method for the diamond composite planar teeth 92 as described.

[0045] The X-axis extends in the left-right direction, the Y-axis extends in the front-back direction, the Z-axis extends in the up-down direction, the C-axis extends in the up-down direction, and the A-axis extends in the left-right direction, and the A-axis is perpendicular to the C-axis.

[0046] During operation, the cylindrical blank 91 to be processed is grabbed from the loading position 83 on the positioning tool 82 and transferred to the fixture 72 for grabbing. With the precise movement of the X-axis slide 3, the Y-axis saddle 4 and the Z-axis saddle 5, the A-axis turntable 71 drives the fixture 72 to rotate, that is, the multi-axis of the machine tool's X-axis, Y-axis, Z-axis and A-axis work together, and different parts of the diamond composite planar tooth 92 can be processed by the scanning galvanometer module 6, thereby realizing the fine processing of multiple surfaces such as the outer circle, chamfer, and front end face to form the diamond composite planar tooth 92.

[0047] The laser processing machine for the diamond composite planar tooth 92 provided by the present invention can perform all-round precision cutting and engraving on the diamond composite planar tooth 92 through multi-axis linkage and A-axis rotation, which significantly improves the processing accuracy and workpiece quality. It also has the function of automatic loading and unloading, greatly improves the processing efficiency, reduces manual intervention, and is suitable for mass production.

[0048] In this embodiment, since the linear motor can realize direct transmission, it has the advantages of light and thin 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 parts to move. The X-axis drive mechanism, the Y-axis drive mechanism, and the Z-axis drive mechanism are all linear motors. The gantry 2 is provided with a Y-axis guide rail, and the Y-axis slide saddle 4 is slidably connected to the Y-axis guide rail through the Y-axis slider. The bed 1 is provided with an X-axis guide rail, and the X-axis slide table 3 is slidably connected to the X-axis guide rail through the X-axis slider; the Y-axis slide saddle 4 is provided with a Z-axis guide rail, and the Z-axis slide saddle 5 is slidably connected to the Z-axis guide rail through the Z-axis slider. The Y-axis slide saddle 4, the X-axis slide table 3, and the Z-axis slide saddle 5 move smoothly and steadily.

[0049] Preferably, a top pull seat 41 is provided on the top of the Y-axis saddle 4, and a balancing cylinder 42 is provided on the Z-axis saddle 5. The cylinder body of the balancing cylinder 42 is fixed on the Z-axis saddle 5, and the end of the piston rod is fixedly connected to the top pull seat 41; the X-axis drive mechanism, the Y-axis drive mechanism, and the Z-axis drive mechanism are all linear motors. By arranging the balancing cylinder 42 on the Z-axis saddle 5 and connecting it to the top pull seat 41 of the Y-axis saddle 4, the balancing cylinder 42 can provide a corresponding reverse force when the Z-axis saddle 5 moves up and down, thereby reducing the load of the linear motor that drives the Z-axis saddle 5 to move up and down, reducing the power demand of the linear motor, and increasing the service life of the linear motor.

[0050] 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 claws, which can provide a more even distribution of clamping force, ensure that the workpiece is stable and motionless during processing, and reduce processing errors caused by workpiece shaking. The three-jaw chuck has an automatic centering function, that is, it can automatically adjust the center of the workpiece to be consistent with the rotation axis of the chuck. This feature is particularly important for the processing of diamond composite flat teeth 92 that require high-precision positioning, which helps to improve processing accuracy and consistency. In addition, the claw spacing of the three-jaw chuck is adjustable, which can adapt to workpieces of different diameters, so that the same device can process diamond composite flat teeth 92 of various sizes, enhancing the versatility and flexibility of the equipment.

[0051] Specifically, the X-axis slide 3 is provided with a bracket 81 and a positioning fixture 82 placed on the bracket 81, and the positioning fixture 82 is provided with a plurality of loading positions 83 for mounting workpieces. It can be understood that before processing, the loading position 83 of the positioning fixture 82 is loaded with a cylindrical blank 91, and after the cylindrical blank 91 is processed into a diamond composite plane tooth 92, the loading position 83 of the positioning fixture 82 is loaded with a diamond composite plane tooth 92.
