Description

Technical Field

[0001] The present invention relates to a drilling machine tool, and more specifically to a laser beam drilling machine tool. Background Art

[0002] In modern industrial production, laser beam drilling machine tools have been widely used in many fields due to their significant advantages such as high precision, high speed, and non-contact processing. From the processing of micro-apertures in electronic device manufacturing to the precision drilling operations of components in the aerospace field, laser beam drilling machine tools play a key role. However, after the existing laser beam drilling machine tools complete the drilling operation, they generally face a rather troublesome problem, that is, a large amount of residue remains around the holes. The existence of these residues not only affects the surface quality of the workpiece but may also have an adverse impact on subsequent processes such as assembly and coating. At present, for the cleaning of residues after drilling, mostly manual cleaning or the cleaning method of secondary auxiliary equipment is adopted. Manual cleaning has low efficiency, and it is difficult to ensure the consistency of the cleaning effect, and it is easy to cause incomplete cleaning due to human factors. And the cleaning of secondary auxiliary equipment requires additional equipment costs and operating procedures, which not only occupies production space but also reduces the overall production efficiency. Therefore, researching and developing a laser beam drilling machine tool that can automatically shovel the residues around the holes after drilling has important practical significance for improving the quality and efficiency of industrial production. Summary of the Invention

Specific implementation mode

[0016] As Figure 5 shown; Since the laser beam drilling machine includes a vertical rod 101, the upper part of the vertical rod 101 is vertically slidably connected with an extending arm 103, the front part of the extending arm 103 is bolted with a laser beam gun 106, the middle part of the vertical rod 101 is vertically slidably connected with two lifting strips 104, and shovels 107 are integrally formed at the front parts of the two lifting strips 104, and the two shovels 107 are arranged oppositely. The extending arm 103 can slide vertically on the vertical rod 101, thereby driving the laser beam gun 106 to lift. After the laser beam gun 106 is lifted and approaches the metal plate, a laser beam is emitted to drill holes in the metal plate; residues will remain around the holes. At this time, drive the two extending arms 103 to lift, so that the two shovels 107 are respectively in contact with both sides of the metal plate, and at this time, the residues remaining around the holes can be shoveled off by horizontally moving the two shovels 107.

[0017] When carrying out the metal plate drilling operation, first, the extending arm 103 slides vertically on the vertical rod 101. This sliding process is controlled by a precise driving device, which can accurately adjust the height position of the extending arm 103, and then drive the connected laser beam gun 106 to lift synchronously. As the laser beam gun 106 gradually approaches the metal plate to be processed, when it reaches the preset drilling position, the laser beam gun 106 instantaneously releases a high-energy laser beam. The laser beam is focused on the surface of the metal plate with extremely high energy density, and the metal material is quickly melted or even vaporized in a very short time, so as to accurately drill holes in the metal plate that meet the design requirements. However, this physical process of laser drilling will inevitably produce some by-products, and residues will remain around the holes. These residues are mainly composed of tiny metal particles that are not completely vaporized under the action of the laser and solidify around the holes, as well as some ablated metal oxides, etc. At this time, control the lifting of the two lifting bars 104 on the vertical rod 101, so that the two shovels 107 can respectively and smoothly contact the two side surfaces of the metal plate. After ensuring that the shovels 107 are fully attached to the metal plate, use the horizontal driving device to push the two shovels 107 to move horizontally along the surface of the metal plate. During the horizontal movement, the two oppositely arranged shovels 107 can completely shovel up and remove the residues remaining around the hole, so that after the metal plate completes the punching operation, its surface remains clean and smooth, greatly improving the processing quality of the workpiece and avoiding a series of subsequent quality problems that may be caused by residue remaining.

[0018] As Figure 5 shown; Since the upper part of the vertical rod 101 is fixed with a first telescopic rod 102, the movable end of the first telescopic rod 102 is fixed on the extending arm 103, and two second telescopic rods 109 are fixed on the vertical rod 101. The movable ends of the two second telescopic rods 109 are respectively fixed on the two lifting bars 104. The first telescopic rod 102 controls the lifting of the extending arm 103 by telescoping, and the two second telescopic rods 109 control the lifting of the two lifting bars 104 by telescoping, finally realizing the control of the lifting of the laser beam gun 106 and the two shovels 107.

[0019] As Figure 5 shown; Since a first motor 105 is bolted to each of the two lifting bars 104, a disc is connected to the output shaft of each of the two first motors 105, and a wire brush 108 is provided on each disc. After the two oppositely arranged shovels 107 completely shovel up the residues remaining around the hole, move the two discs to the position of the hole, so that the two wire brushes 108 respectively move to both sides of the hole, and then the two first motors 105 respectively drive the two wire brushes 108 to rotate. At this time, the high-speed rotating wire brush 108, with its fine and tough wire bristles, further cleans and polishes the hole wall and the surrounding area. During the rotation, the bristles of the wire brush 108 can penetrate into the fine unevenness caused by residue remaining or laser punching, completely brush off the remaining fine particles, and at the same time slightly polish the surface of the hole wall to make it smoother. As the wire brush 108 continues to rotate, metal debris is continuously swept down from the hole wall and the surrounding area. After the fine treatment by the wire brush 108, the quality of the drilled part on the metal plate has been further improved. Not only is the roughness of the hole wall significantly reduced, which is beneficial to subsequent process operations such as thread machining and riveting, but also the stress concentration problem caused by residue residue and surface unevenness is greatly reduced, improving the overall mechanical properties and service life of the workpiece. Compared with traditional laser drilling machines that rely only on manual or simple auxiliary equipment for residue cleaning, the laser beam drilling machine involved in this application realizes the automated and integrated operation of residue cleaning and hole wall grinding through the coordinated operation of the scraper and the wire brush, greatly improving the processing efficiency, reducing the labor cost, and ensuring the stability and consistency of the processing quality, providing a more efficient and reliable solution for the precision processing of modern industry. As Figure 5 shown; Since the sliding arm 203 is welded to the middle part of the rear side of the vertical rod 101, the sliding arm 203 is slidably connected to the upper part of the support column 201 in the front-rear direction. A second motor 202 is connected to the support column 201 by screws. A lead screw 204 is connected to the output shaft of the second motor 202 through a coupling. A nut cooperating with the lead screw 204 is provided at the end of the sliding arm 203. The lead screw 204 and the nut are in threaded cooperation. By driving the rotation of the lead screw 204 by the second motor 202, the sliding arm 203 can be driven to move back and forth on the support column 201, thereby controlling the back-and-forth movement of the vertical rod 101, the first telescopic rod 102, and the lifting strip 104, and further controlling the back-and-forth movement of the laser beam gun 106, the scraper 107, and the wire brush 108 to adjust the position; This precise control function of back-and-forth movement enables the laser beam drilling machine to exhibit extremely high flexibility and adaptability when facing metal plate processing tasks with different specifications and layout requirements. In actual industrial production scenarios, the drilling positions on the metal plate are often diverse and have certain rules. It may be necessary to process multiple holes at different front and rear positions on the same metal plate. By driving the rotation of the lead screw 204 by the second motor 202, the machine tool can quickly and accurately move the laser beam gun 106 to the designated drilling position.

[0020] After completing a drilling operation, the machine tool can quickly adjust the front and rear positions of the laser beam gun 106 and then proceed with the processing of the next hole, without the need for manual frequent repositioning and clamping of the workpiece, greatly improving the processing efficiency. At the same time, this precise position adjustment also ensures the position accuracy of each hole, enabling the processed workpiece to strictly meet the design requirements.

[0021] In the stage of cleaning the residue after drilling, this forward and backward movement function can also be utilized to precisely move the scraper 107 and the wire brush 108 to the position of the hole. After the scraper 107 completes the preliminary removal of the residue around the hole, the second motor 202 drives the sliding arm 203 to further fine-tune the position to ensure that the wire brush 108 can accurately align with both sides of the hole for in-depth cleaning and grinding. In this process, the threaded engagement mode of the lead screw 204 and the nut not only provides a stable and reliable driving force but also enables very fine position adjustment, allowing the wire brush 108 to fully play its role in cleaning and grinding and effectively removing the residual impurities on the hole wall and its periphery.

[0022] In addition, the forward and backward movement adjustment function of this machine tool also facilitates its collaborative operation with other production equipment or technological processes. In an automated production line, the machine tool can flexibly adjust its own position according to the needs of the entire production process and efficiently connect with upstream and downstream equipment. For example, after completing the drilling and cleaning work, the machine tool can accurately convey the workpiece to the next processing link through forward and backward movement, achieving seamless docking of the production process and further enhancing the production efficiency and automation level of the entire production line.

[0023] In summary, this design that controls the forward and backward movement and position adjustment of the laser beam gun 106, the scraper 107, and the wire brush 108 by driving the rotation of the lead screw 204 by the second motor 202 brings higher processing precision, efficiency, and flexibility to the laser beam drilling machine tool, enabling it to better meet the diverse and high-precision processing requirements of modern industrial production.

[0024] As Figure 7 shown; Since the laser beam drilling machine tool also includes two support bars 405, an L-shaped plate 401 is welded to the upper part of each support bar 405. The two L-shaped plates 401 are respectively located on both sides of the laser beam gun 106. The two ends of the metal plate to be drilled need to be respectively placed on the two L-shaped plates 401, and the two L-shaped plates 401 support the metal plate to be drilled. In actual operation, the staff only needs to steadily place the metal plate to be drilled on the two L-shaped plates 401 to quickly complete the preliminary positioning of the metal plate. The special shape of the L-shaped plate 401 can not only provide reliable support for the metal plate in the horizontal direction to prevent its lateral displacement during the laser drilling process but also play a certain limiting role for the metal plate in the vertical direction to reduce the up and down shaking caused by external forces or laser impacts. This is crucial for ensuring that the laser beam can accurately focus on the predetermined drilling position, avoiding drilling deviations caused by the unstable position of the metal plate, and greatly improving the drilling precision and quality.

[0025] Moreover, the structural design of the L-shaped plate 401 makes the placement and removal operations of the metal plate very convenient. After completing a batch of punching tasks, the staff can easily remove the processed metal plate from the L-shaped plate 401 and then quickly replace it with the next metal plate to be processed, effectively shortening the loading and unloading time and improving the overall working efficiency of the machine tool.

[0026] As Figure 7 shown; Since a pressure strip 403 is provided on the upper side of the L-shaped plate 401, two convex columns 404 are fixed on the upper side of the pressure strip 403. Both convex columns 404 are vertically slidably connected to the L-shaped plate 401. A pressure screw 402 is threadedly connected to the L-shaped plate 401. The pressure screw 402 presses on the upper side of the pressure strip 403. By rotating the pressure screw 402, the pressure strip 403 can be driven to press down on the metal plate on the L-shaped plate 401 to clamp the edge of the metal plate. This clamping structure further enhances the fixing effect of the laser beam punching machine tool on the metal plate to be processed. After the metal plate is placed on the L-shaped plate 401 for preliminary support and positioning, by rotating the pressure screw 402, the pressure strip 403 can be smoothly pressed down along the guidance of the convex column 404. The design of the vertical sliding connection of the convex column 404 ensures the stability and perpendicularity of the pressure strip 403 during movement, avoiding uneven clamping of the metal plate due to tilting during the pressing process.

[0027] When the pressure strip 403 is in close contact with the metal plate and applies a certain pressure, the metal plate is firmly fixed on the L-shaped plate 401. This firm clamping method has many important significances. During the laser beam punching stage, the high-energy impact of the laser beam will cause the metal plate to have a tendency of slight vibration and displacement. The effective clamping of the edge of the metal plate by the pressure strip 403 can greatly inhibit this vibration and displacement, ensuring that the laser beam always acts accurately on the predetermined punching position, thereby significantly improving the punching accuracy and quality.

[0028] At the same time, during the subsequent operations of the scraper 107 and the wire brush 108 for residue cleaning and grinding, the metal plate will not shake due to external forces. During the process of the scraper 107 moving horizontally to remove residues and the wire brush 108 rotating at high speed for hole wall cleaning and grinding, the metal plate needs to be kept stable. The clamping effect of the pressure strip 403 provides a reliable guarantee for these operations, enabling the residue cleaning and grinding work to be completed more efficiently and thoroughly.

[0029] Moreover, the clamping method achieved by pressing the screw 402 and the pressing strip 403 has the advantages of simple operation and flexible adjustment. The operator can flexibly rotate the pressing screw 402 according to factors such as the thickness and material of the metal plate to adjust the pressure of the pressing strip 403 on the metal plate, so as to achieve the best clamping effect. Whether it is a thin metal sheet or a thick metal plate, stable and reliable fixation can be achieved in this way.

[0030] In summary, the clamping structure composed of the pressing strip 403, the convex column 404 and the pressing screw 402 on the L-shaped plate 401 closely cooperates with the previous support structure and the drilling and cleaning functions of the machine tool, further improving the overall performance and processing quality of the laser beam drilling machine tool, and ensuring that the machine tool can efficiently and accurately complete the work when facing metal plate processing tasks of different types and specifications.

[0031] As Figures 6 - 7 shown; Since the two support bars 405 are respectively slidably connected to both ends of the rail 306, the rail 306 is arranged on the bottom bar 307, and the lower end of the support bar 405 is threadedly connected with a fastening screw 406. The fastening screw 406 presses on the rail 306, and the support bar 405 can move left and right on the rail 306, thereby adjusting the distance between the two L-shaped plates 401. Rotating the fastening screw 406 to press on the rail 306 can fix the position of the support bar 405; In industrial production, the size specifications of the metal plates to be processed are rich and diverse, ranging from narrow and slender metal strips to wide metal plates. Through the left and right movement function of the support bar 405 on the rail 306, the operator can quickly and conveniently adjust the distance between the two L-shaped plates 401 according to the actual width of the metal plate. Whether it is processing a narrow electronic component metal substrate or a wide mechanical structure metal plate, the machine tool can quickly adapt, without the need to replace the support components cumbersome or carry out complex mechanical modifications. After the distance adjustment is completed according to the width of the metal plate, only need to rotate the fastening screw 406 to press it tightly on the rail 306, then the support bar 405 can be firmly locked in the current position. This method of fastening by thread has a simple operation but can provide strong friction, effectively preventing the support bar 405 from shifting due to factors such as vibration and external impact during the operation of the machine tool, ensuring the stability of the support of the two L-shaped plates 401 for metal plates of different sizes. The flexible adjustment of the distance between the two L-shaped plates 401 is closely coordinated with the drilling and residue cleaning processes of the machine tool. During the drilling stage, an appropriate distance between the L-shaped plates 401 can ensure that the metal plate is stably supported, so that when the laser beam gun 106 drills holes at different positions, the metal plate will not shake due to unstable support, ensuring the drilling accuracy. In the residue cleaning process, whether it is the scraper 107 removing the residue or the wire brush 108 polishing the hole wall, stable support of the metal plate is the prerequisite for efficient operation. Moreover, this structure works in conjunction with the clamping structure of the pressing strip 403 mentioned above. After adjusting the distance between the L-shaped plates 401 to fit the width of the metal plate, the clamping of the edge of the metal plate by the pressing strip 403 further enhances the reliability of the metal plate fixation, ensuring the stability and accuracy of the machine tool processing process from multiple dimensions. As Figures 5 - 6 shown; Since the support column 201 is fixed to the rear of the base 301, a fixed sleeve 308 is provided at the front of the base 301, and the bottom strip 307 is horizontally slidably connected to the fixed sleeve 308. A handle 305 is fixed to one end of the bottom strip 307. By holding the handle 305, the bottom strip 307 can be driven to move left and right on the fixed sleeve 308, thereby enabling the two support strips 405, the two L-shaped plates 401, and the metal plate as a whole to move left and right, adjusting the left and right positions of the metal plate.

[0032] This design provides a very convenient way for operators to adjust the position of the metal plate. During the actual processing, the laser beam drilling machine tool often needs to accurately calibrate the position of the metal plate according to the specific position requirements of drilling. With the help of the handle 305, the staff can easily apply force to smoothly slide the bottom strip 307 left and right on the fixed sleeve 308. This manual operation method is intuitive and easy to control. Whether it is an experienced technical worker or a novice who is new to this machine tool, they can quickly get started and accurately adjust the metal plate to the best position required for laser beam drilling. By moving the bottom strip 307 left and right, driving the two support strips 405 and the L-shaped plates 401 and the metal plate on them to move as a whole, precise fine-tuning of the left and right positions of the metal plate is achieved. When performing drilling operations for multiple holes, if there are differences in the horizontal positions of adjacent holes, the operator only needs to move the metal plate through the handle 305 to quickly align with the next drilling point, without having to reload the metal plate or perform complex re-calibration of the position of the laser beam gun 106. This not only greatly saves processing time and improves production efficiency, but also avoids errors that may be introduced due to frequent loading and unloading and equipment adjustment, further ensuring the accuracy of the drilling position and the stability of the processing quality. As Figure 6 shown; Since the base 301 is fixed with a lug 302, two round rods 303 are slidably connected to the lug 302. A press head 304 is fixed to the front parts of the two round rods 303. The press head 304 presses on the rear side of the bottom strip 307. A compression spring is sleeved on each round rod 303. The compression spring is located between the lug 302 and the press head 304. The compression spring always gives the press head 304 and the two round rods 303 a forward pressure, so that the bottom strip 307 is always pressed by the press head 304, making it convenient to fix the bottom strip 307 after it moves left and right; This spring pressure fixing structure provides a simple and effective solution for the position locking of the bottom strip 307. After the operator drives the bottom strip 307 to move left and right on the fixed sleeve 308 by holding the handle 305 to complete the adjustment of the left and right positions of the metal plate, the existence of the compression spring ensures that the press head 304 can continuously apply a stable pressure to the bottom strip 307. The frictional force generated by this pressure effectively prevents the bottom strip 307 from accidentally sliding during subsequent operations such as punching and residue cleaning, ensuring the stability of the position of the metal plate, thereby further improving the processing accuracy.

[0033] In actual operation, when the position of the bottom strip 307 needs to be adjusted, the operator only needs to overcome the pressure of the compression spring and pull the press head 304 backward to reduce the frictional force between the press head 304 and the bottom strip 307. At this time, the bottom strip 307 can slide smoothly left and right on the fixed sleeve 308. When the bottom strip 307 moves to the target position, release the press head 304, and the compression spring will immediately restore its deformation, pushing the press head 304 to press tightly on the bottom strip 307 again, quickly realizing the fixation of the bottom strip 307. This operation method is simple and fast, without the need for additional complex tools or cumbersome operation steps, greatly improving the use efficiency of the machine tool.

[0034] In addition, the elastic characteristics of the compression spring enable the pressure of the press head 304 on the bottom strip 307 to have a certain self-adaptive ability. No matter where the bottom strip 307 is on the track, the compression spring can provide an appropriate pressure according to the actual situation to ensure that the bottom strip 307 is reliably fixed. Moreover, this elastic pressure can also buffer the vibration generated during the operation of the machine tool to a certain extent, reducing the influence of vibration on the position stability of the bottom strip 307, and further ensuring the reliability of the metal plate processing process.

[0035] As Figures 1 - 8 shown; Since the lower end of the vertical rod 101 is fixed to the rear end of the connecting rod 505, the front end of the connecting rod 505 is fixed to the lower end of the vertical column 501, and two bars 503 are vertically slidably connected to the vertical column 501, and the upper and lower ends of the vertical column 501 are fixed with telescopic rods 3 502, and the ends of the two telescopic rods 3 502 are respectively fixed to the two bars 503, and the conical cover 504 is fixed on the upper bar 503, and the conical bowl 506 is fixed on the lower bar 503. The connecting rod 505, the conical bowl 506 and the laser beam gun 106 are coaxially arranged. When the vertical rod 101 moves, it drives the vertical column 501, the bar 503, the conical cover 504, and the conical bowl 506 to move synchronously through the connecting rod 505. When drilling, the two telescopic rods 502 extend and retract to drive the two bar 503 to rise and fall, and then drive the conical cover 504 and the connecting rod 505 to contact the upper and lower sides of the metal plate respectively. During the drilling process, the close contact between the conical cover 504 and the upper surface of the metal plate effectively blocks the high-temperature sputtering generated by the laser drilling process from splashing upward, avoiding contamination of other machine components and the working environment. The conical bowl 506, in contact with the lower surface of the metal plate, can receive residue and debris that falls from the bottom of the metal plate, preventing it from scattering and facilitating subsequent centralized cleaning. Furthermore, because the connecting rod 505, conical bowl 506, and laser beam gun 106 are coaxially arranged, residue and debris are ensured to fall smoothly into the conical bowl 506 as the laser beam penetrates the metal plate, preventing deflection and the resulting difficulty in cleaning. Furthermore, this structural design further concentrates the laser beam's energy during the drilling process, reducing energy scattering and further improving drilling accuracy and quality. After completing a hole, telescopic rod 502 rapidly reverses, driving conical cover 504 and conical bowl 506 to separate from the metal plate.
