Description

Technical Field

[0001] The invention relates to the technical field of numerical control machining, and in particular to a multi-angle numerical control machining device. Background Art

[0002] The existing CNC processing device is specifically a device for punching holes in metal materials. The device uses a laser punching method and has the advantages of high precision, high speed and diversified punching. The device itself uses a high-energy-density laser beam to focus on the surface of the metal plate to melt or vaporize the material instantly to form holes. It is often used in the processing of metal shells of electronic equipment;

[0003] In the Chinese patent with the patent publication number CN113829078A, a laser drilling auxiliary drilling device and method are disclosed, including: a continuous laser generating system, which emits a continuous laser beam that passes through the drill bit of a CNC machine tool and irradiates the surface of a workpiece, and an auxiliary installation system, which slides and installs the continuous laser focusing head of the continuous laser generating system on the spindle of the CNC machine tool, and makes the continuous laser focusing head rotate with the spindle. The laser drilling auxiliary drilling method includes four steps: a preparation stage, the spindle of the machine tool drives the continuous laser focusing head to rotate, and processing the bottom hole and the remaining part of the processing hole. The laser drilling auxiliary drilling device and method have higher processing efficiency and lower surface damage, realize the drilling processing of composite difficult-to-process materials, and reduce costs;

[0004] However, the equipment and prior art in the cited documents still have the following defects when used in practice:

[0005] 1. Compared with the device in the reference document, the movement mode of the laser head in the drilling process adopts the traditional linear reciprocating motion mode, that is, after completing a drilling, the laser head can continue the drilling operation after the drilling material is moved. In this process, when the laser head reaches the positive limit position to complete the drilling, its speed will suddenly drop from the maximum value in the positive direction to zero, and then accelerate in the reverse direction. This sudden change in speed means that the acceleration has changed dramatically. Since the laser head is a mass object, when the acceleration changes so sharply, the force acting on the laser head will also change suddenly. For the laser head itself, this sudden change in force will cause its internal components to bear additional stress, thereby accelerating the wear of the laser head. For the drilling material, due to the impact of the laser head, the laser beam cannot act on the material stably during drilling, which leads to the appearance of uneven hole sizes and uneven surface during drilling.

[0006] At the same time, during the laser drilling process, the laser beam is focused on the metal material, causing the material to melt and vaporize rapidly. In this process, high-temperature and high-pressure steam is generated, which in turn forms gas heat. Moreover, when the metal material vaporizes at high temperature, it will react chemically with the surrounding air. For example, copper metal reacts with oxygen at high temperature to form compounds such as copper oxide, which emit a special odor. In addition, if some lubricants or coolants are used during the drilling process, these substances will also partially decompose and produce odors at high temperatures. The gas heat will be conducted to the metal material area around the drilling, forming a heat-affected zone, thereby reducing the performance of the material, and the odor will make the working environment unpleasant, reducing the operator's work comfort and work efficiency;

[0007] 2. Compared with the existing technology, with the long-term use of the equipment, some mechanical parts connected to the laser head, such as guide rails and lead screws, will wear out. The wear of the guide rails will make the movement of the laser head less stable and accurate, and the wear of the lead screw will affect the positioning accuracy of the laser head. For example, after thousands of hours of use, due to frequent reciprocating motion, the pitch of the lead screw will change slightly, which will cause the laser head to fail to accurately reach the preset position when drilling. However, it is difficult for workers to distinguish relatively subtle deviations by observation, which makes these deviations accumulate continuously in the production process. As time goes by, the impact on the consistency of drilling becomes greater and greater, resulting in various inconsistencies in the drilling of a recent batch of materials, such as deviations in parameters such as hole depth, position, and diameter;

[0008] In view of this, the present invention proposes a multi-angle CNC machining device to compensate for and improve the deficiencies of the prior art. Summary of the invention

[0009] In order to solve the above technical problems, the present invention provides a multi-angle CNC machining device to solve the technical problems raised in the above background technology.

[0010] To achieve the above objectives, the technical solution adopted by the present invention is: a multi-angle CNC processing device, used for CNC punching processing on processing materials, including a CNC module, a driving module is installed above the CNC module, a laser module is installed inside the driving module, and the side wall of the driving module is provided with an efficient punching and heat dissipation mechanism, and the efficient punching and heat dissipation mechanism adopts a periodic sinusoidal wave movement mode to continuously punch the processing material.

[0011] Furthermore, the efficient perforated heat dissipation mechanism includes a cam plate symmetrically installed on the side wall of the driving module, the side walls of the cam plate are installed with driven plates, the side walls of the driven plates are fixedly connected with fixed columns, the outer walls of the fixed columns are slidably connected with limited position rails, and the lower side walls of the driven plates are rotatably connected with a connecting frame.

[0012] Furthermore, the side walls of the cam plate are fixedly connected with cylindrical protrusions, and the cam plate and the driven plate are rotationally connected via the cylindrical protrusions.

[0013] Furthermore, the outer wall of the laser output end of the laser module is installed with a poly-shell, the inner wall of the poly-shell is installed with an adsorption ring, the output end of the poly-shell is fixedly connected with a turbine group, and the inner wall of the poly-shell is slidably connected with a baffle.

[0014] Furthermore, the poly-center shell is in the shape of a funnel that is narrow at the top and wide at the bottom. The interior of the poly-center shell is hollowed out. The hollowed-out part inside the poly-center shell is cylindrical as a whole. The bottom of the poly-center shell is composed of a combination of transparent materials.

[0015] Furthermore, the adsorption ring is entirely made of activated carbon material, circular holes are evenly penetrated through the outer wall of the adsorption ring, and the adsorption ring is integrally slidably connected to the cylindrical portion inside the polycarbonate shell.

[0016] Furthermore, the turbine group as a whole is composed of a plurality of incomplete arc plates, and each incomplete arc plate is installed in an inclined manner.

[0017] Furthermore, a monitoring, positioning and calibration mechanism is provided on the side wall of the driving module, and the monitoring, positioning and calibration mechanism is used to monitor whether the laser module is offset during the punching process. The monitoring, positioning and calibration mechanism includes a mapping plate installed on the side wall of the driving module, and a light shield is fixedly connected to the surface of the mapping plate, and a transparent mirror is installed on the side wall of the light shield.

[0018] Furthermore, a precision groove is provided at the exact center of the surface of the mapping plate, and scale lines are symmetrically provided on both sides of the precision groove. The precision groove on the surface of the mapping plate is initially parallel to the laser output end of the laser module.

[0019] Furthermore, the transparent mirror is integrally fixedly connected to the side wall of the mapping plate, and the transparent mirror is kept parallel to the precise grooves and scale lines on the surface of the mapping plate.

[0020] Furthermore, the laser module includes a laser generator, a laser nozzle and an optical fiber. The laser generator and the laser nozzle are slidably connected. The connecting frame is integrally sleeved on the outer wall of the laser generator in the laser module. The poly-middle shell is integrally fixedly connected to the outer wall of the laser nozzle in the laser module.

[0021] Furthermore, the CNC module includes a controller, an operating table and a programming system, which mainly controls the movement of the laser nozzle in the laser module and the laser output. The driving module includes a driving motor and a guide rail group. The cam plates are fixedly connected to the outer wall of the output shaft end of the driving motor in the driving module, and the limit rails are slidably connected to the side walls of the guide rail group in the driving module.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] (1) This device uses the periodic circular motion of the cam plate and the horizontal limit of the limit rail to enable the laser nozzle to follow the connecting frame to perform periodic sinusoidal motion. First, the sinusoidal motion mode ensures that the speed and acceleration of the laser nozzle change smoothly and without sudden changes during the entire drilling process, reducing the vibration and impact of its internal structure movement, thereby improving the stability of the equipment's drilling processing movement. This is not only conducive to protecting the precision components inside the laser head from damage by additional stress and extending the service life of the equipment, but also significantly improves the controllability and accuracy of the processing process;

[0024] Secondly, since the movement of the laser nozzle is more stable, the laser beam can act more stably on the material to be punched, effectively avoiding problems such as inconsistent hole size and increased surface roughness caused by discontinuous movement. This improvement directly improves the punching accuracy and surface quality, making the processed hole diameter more uniform and the surface smoother, meeting the needs of high-precision processing;

[0025] Finally, through the precise coordination between the cam plate and the limit rail, the laser head motion trajectory is precisely controlled, which reduces unnecessary energy loss and heat accumulation, optimizes the dynamic performance of the equipment drive, and thus improves the energy conversion efficiency in the equipment, and also reduces the noise and heat emission during the operation of the equipment.

[0026] More importantly, the device introduces a poly-shell to ensure that the bottom of the poly-shell is in close contact with the punching material when the laser nozzle is drilling, forming a relatively closed working area. This design effectively isolates and gathers the hot air and odorous gases generated during the drilling process inside the poly-shell to prevent them from spreading to the entire working environment. In addition, the isolation effect of the poly-shell, combined with the purification and adsorption of odor by the built-in adsorption ring, significantly reduces the emission of odorous gases during the drilling process, which not only improves the air quality of the working environment, but also reduces the risk of operators inhaling harmful gases, thereby improving work comfort and health.

[0027] Secondly, the movable small piston structure formed by the poly shell and the baffle plate generates an upward suction when the laser nozzle moves upward after drilling is completed, effectively absorbing the hot air and odor generated on the surface of the punched material. On this basis, combined with the upward flow characteristic of hot air, the hot air can be more effectively maintained inside the poly shell, thereby improving the hot air processing efficiency, reducing the heat accumulation in the external environment of the equipment, and at the same time avoiding the conduction of hot air to other areas of the punched material, which helps to inhibit the formation of heat-affected zones. At the same time, the hot air can also be maintained in the poly shell, thereby ensuring the temperature of the overall environment outside the laser nozzle, thereby reducing the thermal stress and thermal deformation of the laser nozzle caused by temperature changes;

[0028] Among them, a turbine group composed of a plurality of incomplete arc plates installed in an inclined manner is introduced at the output port of the poly shell, so that the hot gas surrounds the outside of the laser nozzle in a spiral form and flows upward. The spiral gas flow path increases the contact time and contact area between the hot gas and the outer wall of the laser nozzle, thereby more effectively cleaning the debris remaining on the outer wall. In addition, this surrounding and wrapping flow mode can ensure that the debris is completely and thoroughly taken away, avoiding the interference or damage that the debris may cause to the subsequent work of the laser nozzle;

[0029] Compared with the conventional straight airflow, the spiral airflow has a tangential velocity component, which can exert a lateral force on the debris on the outer wall of the nozzle. According to Newton's second law, this force will cause the debris to overcome the adsorption force and move. Therefore, the spiral airflow can cover the outer wall of the nozzle more comprehensively, so that the debris is affected by the airflow in all directions, thereby improving the efficiency of debris removal.

[0030] The appearance of the poly-middle shell introduced in the device is generally in the shape of a funnel that is narrow at the top and wide at the bottom. The hollowed-out part inside is cylindrical. The cylindrical space can provide a stable running track for the laser nozzle, avoiding collision or jamming of the nozzle due to space limitations during movement. The bottom design of the funnel-shaped poly-middle shell increases the contact area with the surface of the punching material, thereby more effectively isolating the high temperature generated during the punching process from being transferred to other parts.

[0031] (2) The device introduces a mapping plate on the side wall of the laser nozzle, and in the initial state, ensures that the mapping plate and the output ends of multiple laser nozzles are in the same horizontal plane, and the output port of the laser nozzle is parallel to the precise groove in the center of the mapping plate. Therefore, when the laser head works normally, the laser will form a specific projection relationship on the mapping plate. From the perspective of optical geometry, this setting provides an intuitive reference frame for the staff. Through the projection of the laser and the specific marks on the mapping plate, the standard optical path and imaging relationship are pre-set, which is convenient for subsequent staff monitoring. In addition, this structure can realize simultaneous monitoring of multiple laser nozzles. In large-scale production, multiple laser nozzles are often used for drilling operations at the same time. This structure can obtain the status information of multiple nozzles at one time, thereby improving the monitoring efficiency, and there is no need to set up complex monitoring equipment for each nozzle separately, thereby saving equipment investment costs;

[0032] In addition, by observing whether the scale lines on both sides of the center line of the mapping plate coincide with the laser, it is possible to determine whether the laser head is offset. At the same time, the specific offset direction of the laser nozzle can be distinguished. Adjustment can be made according to the offset direction to minimize the error in the adjustment process. When the specific offset direction is known, the adjustment operation can be more targeted in the direction of correcting the deviation, which helps to quickly restore the laser head to the correct position and reduce new errors introduced by multiple trial and error adjustments, thereby greatly improving the accuracy and efficiency of the adjustment.

[0033] Compared with the existing technology, some indirect measurement methods are often required, such as measuring the operating parameters of the equipment, analyzing the statistical data of the drilling results, etc., and these indirect methods have certain lags and inaccuracies. The device realizes direct observation of the status of the laser head through the mapping board, which not only allows for quick and intuitive judgment, but also does not require complex data analysis, thereby reducing the requirements for personnel's professional skills and at the same time reducing the cost and time investment of data analysis.

[0048] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention;

[0049] It should be noted that the structures and working principles of the above-mentioned numerical control module 1, driving module 11, laser module 12, processing material 13 and other devices belong to the prior art and will not be described in detail here.

[0050] Example 1

[0051] Please refer to Figure 1As shown, a multi-angle CNC processing device is used for CNC punching processing on a processing material 13, comprising a CNC module 1, a driving module 11 is installed above the CNC module 1, a laser module 12 is installed inside the driving module 11, and a high-efficiency punching heat dissipation mechanism 2 is provided on the side wall of the driving module 11, and the high-efficiency punching heat dissipation mechanism 2 uses a periodic sinusoidal wave motion mode to continuously punch the processing material 13;

[0052] It should be noted that the laser module 12 includes a laser generator, a laser nozzle and an optical fiber. The laser generator and the laser nozzle are slidably connected. The connecting frame 25 is integrally sleeved on the outer wall of the laser generator in the laser module 12. The poly-middle shell 26 is integrally fixedly connected to the outer wall of the laser nozzle in the laser module 12. The CNC module 1 includes a controller, an operating table and a programming system, which mainly controls the movement of the laser nozzle in the laser module 12 and the laser output. The driving module 11 includes a driving motor and a guide rail group. The cam disc 21 is fixedly connected to the outer wall of the output shaft end of the driving motor in the driving module 11, and the limit rails 24 are slidably connected to the side walls of the guide rail group in the driving module 11.

[0053] Please refer to Figures 2 to 8 As shown, the high-efficiency perforated heat dissipation mechanism 2 includes a cam plate 21 symmetrically mounted on the side wall of the driving module 11, and the side walls of the cam plate 21 are all mounted with a driven plate 22, and the side walls of the driven plate 22 are all fixedly connected with a fixed column 23, and the outer wall of the fixed column 23 is slidably connected with a limited position rail 24, and the lower side wall of the driven plate 22 is rotatably connected with a connecting frame 25;

[0054] It should be noted that the side walls of the cam plate 21 are fixedly connected with cylindrical protrusions, and the cam plate 21 and the driven plate 22 are rotationally connected via the cylindrical protrusions.

[0055] Specifically, the rotation of the cam disc 21 itself is a process of periodic circular motion. Since the driven plate 22 is connected to the eccentric position of the cam disc 21, during the rotation of the cam disc 21, the connection point of the driven plate 22 also performs circular motion on the cam disc 21. Because it is an eccentric connection, the distance from the connection point to the center of the cam disc 21 is fixed, but its projection relative to the horizontal direction will change periodically with the rotation of the cam disc 21. From the vertical direction, when the connection point is at the top of the cam disc 21, the vertical displacement is the largest. When the connection point is turned to the horizontal position of the cam disc 21, the vertical displacement is zero. When the connection point is turned to the bottom of the cam disc 21, the vertical displacement reaches the negative maximum value. The change of this vertical displacement is like a sine function, which changes periodically from the maximum value to the minimum value and then to the maximum value. Similarly, in the horizontal direction, the projection of the connection point relative to the horizontal direction will also change periodically with the rotation of the cam disc 21. This change law is also similar to the sine function. Therefore, the driven plate 22 will perform regular sinusoidal wave motion with the rotation of the cam disc 21.

[0056] The sinusoidal wave motion mode ensures that the speed and acceleration of the laser nozzle change smoothly and without mutation during the entire drilling process, reducing the vibration and impact of its internal structure movement, thereby improving the smoothness of the equipment's drilling processing movement. This not only helps protect the precision components inside the laser head from damage by additional stress, extending the service life of the equipment, but also significantly improves the controllability and precision of the processing process.

[0057] It should be noted that the outer wall of the laser output end of the laser module 12 is installed with a poly-middle shell 26, the inner wall of the poly-middle shell 26 is installed with an adsorption ring 27, the output end of the poly-middle shell 26 is fixedly connected to a turbine group 28, the inner wall of the poly-middle shell 26 is slidably connected to a baffle plate 29, the poly-middle shell 26 as a whole is in the shape of a funnel that is narrow on the top and wide on the bottom, the interior of the poly-middle shell 26 is hollowed out, the hollow part inside the poly-middle shell 26 is cylindrical as a whole, the bottom of the poly-middle shell 26 is composed of a combination of transparent materials, the adsorption ring 27 is composed of activated carbon material as a whole, the outer wall of the adsorption ring 27 is evenly penetrated with circular holes, and the adsorption ring 27 is slidably connected to the cylindrical part inside the poly-middle shell 26 as a whole, and the turbine group 28 is composed of a plurality of incomplete arc plates, and each incomplete arc plate is installed in an inclined manner.

[0058] Specifically, when the laser nozzle moves downward, the baffle plate 29 will move downward synchronously with it. When the drilling process is completed, the baffle plate 29 will also move upward synchronously with the laser nozzle. Since the baffle plate 29 and the poly-middle shell 26 constitute a similar small piston structure, when the baffle plate 29 moves upward, the space inside the poly-middle shell 26 gradually becomes larger, and at this time, the air pressure inside the poly-middle shell 26 is less than the air pressure outside the poly-middle shell 26, so that suction is generated inside the poly-middle shell 26. On this basis, combined with the upward flow characteristic of hot air, the hot air can be more effectively maintained inside the poly-middle shell 26, thereby improving the processing efficiency of the hot air, reducing the heat accumulation in the external environment of the equipment, and at the same time avoiding the conduction of hot air to other areas of the punching material, which helps to inhibit the formation of a heat-affected zone;

[0059] The hot gas mainly includes airflow and odorous gas. The odorous gas can be purified and adsorbed by the adsorption ring 27, and a small part of the hot gas will be lost, and the other part will be pre-stored in the poly-middle shell 26. As the subsequent drilling continues, new hot gas will continue to be generated. The newly generated hot gas will replace the pre-stored hot gas and squeeze the previous hot gas upward from the poly-middle shell 26.

[0060] Since a turbine group 28 composed of a plurality of incomplete curved plates installed in an inclined manner is introduced at the outlet of the poly-middle shell 26, the incomplete curved plates installed in an inclined manner play a significant guiding role in the airflow. When the airflow passes through the turbine group 28, the inclination angle of the curved plates will guide the flow of the gas. Since the curved plates are not installed perpendicular to the flow direction of the gas but are inclined, when the gas hits the surface of the curved plates, it will be subjected to an oblique force. This oblique force will change the flow direction of the gas, and the gas will no longer flow in a straight line, but will begin to deviate to one side. Since a plurality of curved plates are combined to form the turbine group 28, the effect of each curved plate on changing the flow direction of the gas will accumulate. Finally, as the gas continues to flow, its flow direction is constantly changed, thereby forming a spiral flow trajectory. The spiral gas flow path increases the contact time and contact area between the hot gas and the outer wall of the laser nozzle. During the laser drilling process, static electricity will be generated due to the interaction between the laser and the material. The generated debris will be attracted by the static electricity of the outer wall of the laser nozzle because it carries its own charge or is induced to be charged. Part of the debris will be adsorbed on the outer wall of the nozzle through this static attraction. The device relies on guiding the hot air and making the hot air flow upward in a spiral form. The spiral airflow will generate centrifugal force and axial force during the flow process. The centrifugal force acts on the debris, which can make it move away from the outer wall of the nozzle, thereby effectively cleaning up the remaining adsorbed debris on the outer wall. In addition, this surrounding and wrapped flow method can ensure that the debris is fully and thoroughly taken away, avoiding the interference or damage that the debris may cause to the subsequent work of the laser nozzle.

[0061] Example 2

[0062] Based on Example 1, please refer to Fig. 9 and Fig.10 As shown, a monitoring positioning and calibration mechanism 3 is provided on the side wall of the driving module 11, and the monitoring positioning and calibration mechanism 3 is used to monitor whether the laser module 12 is offset during the drilling process. The monitoring positioning and calibration mechanism 3 includes a mapping plate 31 installed on the side wall of the driving module 11, and a light shield 32 is fixedly connected to the surface of the mapping plate 31, and a transparent mirror 33 is installed on the side wall of the light shield 32;

[0063] It should be noted that a precise groove is provided at the exact center of the surface of the mapping plate 31, and scale lines are symmetrically provided on both sides of the precise groove. The precise groove on the surface of the mapping plate 31 is initially parallel to the laser output end in the laser module 12, and the transparent mirror 33 is integrally fixedly connected to the side wall of the mapping plate 31, and the transparent mirror 33 is parallel to the precise groove and scale lines provided on the surface of the mapping plate 31.

[0064] Specifically, from an optical principle, when the laser nozzle is in a normal state, the laser beam is emitted vertically, and then a straight laser line is formed on the mapping plate 31, and it is parallel to the precise groove at the center of the mapping plate 31. After a long period of use, when the internal components of the laser nozzle are worn and deviate, the emission direction of the laser beam will change, and a laser line deviating from the center will appear on the mapping plate 31. Since multiple laser nozzles and the mapping plate 31 are on the same horizontal plane and are initially set to be parallel, this deviation can be observed intuitively, just like a beam of parallel light passing through a plane mirror. If the mirror is placed vertically, the reflected light is also parallel, but if the mirror is tilted, the reflected light will deviate from the original direction, and this deviation can be seen on the surrounding reference surfaces;

[0065] The staff can distinguish the offset problem of the laser nozzle only by observing the overlap between the scale lines and the laser on both sides of the center line of the mapping plate 31. Since each laser nozzle has a corresponding laser line projected on the mapping plate 31, these laser lines should be parallel and symmetrically distributed on both sides of the center line of the mapping plate 31 under normal circumstances. Once a laser nozzle is offset, its corresponding laser line will be significantly different from the laser lines of other normal laser nozzles. This difference can be used as a basis for judging whether the laser nozzle is offset and which laser nozzle is offset.

[0066] This detection method is a non-contact detection, which does not require the laser nozzle to be disassembled or directly contacted for measurement. During the operation of the equipment, the staff can observe the laser line on the mapping plate 31 at any time without interfering with the normal operation of the equipment. Compared with the traditional method that requires stopping the machine and disassembling equipment parts for measurement, during the continuous production process, if the laser nozzle is suspected to have an offset problem, a preliminary judgment can be made quickly by observing the mapping plate 31, without interrupting the production process for complex detection;

[0067] At the same time, for the staff, this detection method is very intuitive. It does not require complex measuring instruments and professional measurement skills. It only needs to observe the position relationship of the laser line with the naked eye. This reduces the requirements for the technical level of the staff, facilitates the rapid discovery of problems at the production site, and can promptly discover the offset problem of the laser nozzle and take corresponding measures.

[0068] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
