Description

Technical Field

[0001] This utility model relates to the field of drilling device technology, specifically a drilling machine with automatic lifting of a module mechanism. Background Technology

[0002] Drilling machines are mainly used in drilling technology. During the production process, many semi-finished products require drilling for further processing. For example, a mold frame is a semi-finished product of a mold, composed of various steel plates and fitting parts. Therefore, drilling is necessary for assembly and positioning of the mold. For instance, application number CN202122117985.4 discloses a drilling mechanism for mold frame processing. This mechanism allows adjustment of the distance between the first motor and the drill bit based on the front-to-back distance of the holes on the mold frame. By setting up a positioning mechanism, it provides positioning and fixing functions when processing holes on the left and right lines of the mold frame, reducing the labor intensity of workers.

[0003] The drilling mechanism for mold frame processing described above still has the following shortcomings: During the drilling process, the positioning of the part to be drilled and the up-and-down movement of the drilling machine are particularly important. If the part to be drilled is not positioned accurately, the drilling position will be inaccurate. If the up-and-down movement of the drilling machine is unstable, the drilling bit will impact the part to be drilled, which may damage the drill bit or the part to be drilled. In the existing technology, most of the drilling bit is moved by pneumatic means. However, the cylinder will vibrate when it is ventilated, which will affect the drilling machine's ability to drill the part.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a punching machine with automatic lifting of the module mechanism to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this utility model is to provide a drilling machine with automatic lifting of module mechanism to solve the problem mentioned in the background art of avoiding the impact of the drilling bit on the drilling part, which would damage the drilling bit or the drilling part.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a punching machine with an automatic lifting module mechanism, comprising a first fixed plate, a second fixed plate, a third fixed plate, and a punching mechanism. The first fixed plate is connected to the second fixed plate via a sliding module, and the second fixed plate is connected to the third fixed plate via a sliding module. The third fixed plate is connected to the punching mechanism via a guide rail. The punching mechanism includes a punching slide, a punching cylinder, and a servo motor. The punching slide is slidably mounted on one side of the third fixed plate, and the punching cylinder is mounted on the punching... On one side of the slide, a servo motor is installed on the side of the drilling slide away from the drilling cylinder. A buffer assembly is installed on one side of the drilling cylinder, and a drilling motor is installed on the side of the drilling cylinder away from the buffer assembly. A drive wheel is installed at the output shaft of the servo motor, and a driven wheel is connected to the drive wheel via a synchronous belt. The driven wheel is installed on one side of the threaded rod. An extension block is extended on one side of the drilling slide. A drilling bit is installed at the output shaft of the drilling motor, and a protective cover is provided at the end of the drilling motor where the drilling bit is installed.

[0007] Furthermore, the sliding module includes a servo electric cylinder and a slide rail. Two sets of servo electric cylinders are provided, and the two sets of servo electric cylinders are respectively installed on the upper end surfaces of the first fixed plate and the second fixed plate. Slide rails are provided on the upper end surfaces of both the first fixed plate and the second fixed plate, and slide grooves are provided on the bottom end surfaces of both the second fixed plate and the third fixed plate. One set of servo electric cylinders is fixedly connected to the second fixed plate, and the other set of servo electric cylinders is fixedly connected to the third fixed plate.

[0008] Furthermore, the second fixed plate forms a sliding structure with the first fixed plate through a sliding module, the third fixed plate forms a sliding structure with the second fixed plate through a sliding module, and the guide rail and the drilling slide form a sliding structure.

[0009] Furthermore, the buffer assembly includes a slide rod and a buffer spring. The two ends of the slide rod are fixedly connected to the third fixing plate. Two sets of extension blocks are provided. One set of extension blocks is installed on the outer surface of the slide rod, and one set of extension blocks forms an up-and-down sliding structure with the slide rod. The other set of extension blocks is installed on the outer surface of the threaded rod, and the extension blocks are fixedly threadedly connected to the threaded rod.

[0010] Furthermore, the telescopic end of the drilling cylinder is fixedly connected to the drilling slide, and the end of the drilling cylinder away from the drilling slide is fixedly connected to the third fixed plate. The driving wheel and the driven wheel form a belt drive structure through a synchronous belt, and the drilling motor and the drilling drill bit form a shaft drive structure through an output shaft.

[0011] Furthermore, a fine-tuning knob is provided on one side of the first fixing plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the automatic lifting and lowering drilling machine of this module mechanism reduces the vibration generated by the cylinder at the moment of air supply through the buffer component, thereby avoiding the drilling bit from impacting the drilling part, which may damage the drilling bit or the drilling part, and ultimately affect the drilling machine's ability to drill the part. At the same time, the lifting and lowering of the drilling machine can be controlled by the servo motor and the threaded rod, thereby improving the drilling accuracy.

[0013] The automatic lifting drilling machine of this module adjusts one side of the drilling slide through a drilling cylinder, and the telescopic end of the drilling cylinder is fixedly connected to the drilling slide. The end of the drilling cylinder away from the drilling slide is fixedly connected to the third fixed plate. At the same time, the guide rail and the drilling slide form a sliding structure. Therefore, the drilling slide is moved up and down by controlling the drilling cylinder, thereby adjusting the position of the drilling motor. When the drilling cylinder is started to adjust the position of the drilling motor, the vibration generated by the instantaneous air flow of the drilling cylinder is offset by the buffer component, thereby preventing the drilling bit from impacting the workpiece and causing potential damage to the drilling bit or the workpiece, which would ultimately affect the drilling machine's ability to drill holes in the workpiece.

[0014] The automatic lifting and lowering drilling machine of this module starts the servo motor. The driving wheel and the driven wheel form a belt drive structure through a synchronous belt. At the same time, the extension block is fixedly threaded to the threaded rod. The rotation of the servo motor drives the threaded rod to rotate, thereby controlling the drilling slide to move up and down through the servo motor, and thus adjusting the position of the drilling motor. Adjusting the position of the drilling motor through the servo motor has higher precision, so as to complete the drilling of parts with high precision requirements. At the same time, a micro-adjustment knob is installed on one side of the first fixed plate to adjust the relative position between the fixed plates, thereby further improving the drilling accuracy.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 7This utility model provides a technical solution: a punching machine with an automatic lifting module mechanism, including a first fixed plate 1, a second fixed plate 2, a third fixed plate 3, and a punching mechanism 4. The first fixed plate 1 is connected to the second fixed plate 2 via a sliding module 5, and the second fixed plate 2 is connected to the third fixed plate 3 via a sliding module 5. The third fixed plate 3 is connected to the punching mechanism 4 via a guide rail 6. The punching mechanism 4 includes a punching slide 401, a punching cylinder 402, and a servo motor 403. The punching slide 401 is slidably mounted on one side of the third fixed plate 3, the punching cylinder 402 is mounted on one side of the punching slide 401, and the servo motor 403 is mounted on the side of the punching slide 401 away from the punching cylinder 402. A buffer assembly 404 is installed on one side of the drilling cylinder 402, and a drilling motor 405 is installed on the side of the drilling cylinder 402 away from the buffer assembly 404. A drive wheel 406 is installed at the output shaft of the servo motor 403, and a driven wheel 408 is connected to the drive wheel 406 via a synchronous belt 407. The driven wheel 408 is installed on one side of the threaded rod 409. An extension block 4010 is extended on one side of the drilling slide 401. A drilling drill bit 4051 is installed at the output shaft of the drilling motor 405, and a protective cover 4052 is provided at the end of the drilling motor 405 where the drilling drill bit 4051 is installed. A micro-adjustment knob 7 is provided on one side of the first fixed plate 1. The drilling cylinder 402 is used to adjust the drilling process. 02. Adjust one side of the drilling slide 401, and fix the telescopic end of the drilling cylinder 402 to the drilling slide 401. The end of the drilling cylinder 402 away from the drilling slide 401 is fixedly connected to the third fixed plate 3. At the same time, the guide rail 6 and the drilling slide 401 form a sliding structure. Therefore, the drilling cylinder 402 is used to control the drilling slide 401 to move up and down, thereby adjusting the position of the drilling motor 405. When the drilling cylinder 402 is started to adjust the position of the drilling motor 405, the vibration generated at the moment the drilling cylinder 402 is vented is offset by the buffer component 404 to prevent the drilling bit 4051 from impacting the drilled part, which could lead to damage to the drill bit or the drilled part and affect the drilling machine's performance. When drilling is performed on the part, the servo motor 403 is started. Since the driving wheel 406 and the driven wheel 408 form a belt drive structure through the synchronous belt 407, and the extension block 4010 is fixedly threadedly connected to the threaded rod 409, the servo motor 403 rotates, driving the threaded rod 409 to rotate. The servo motor 403 controls the drilling slide 401 to move up and down, thereby adjusting the position of the drilling motor 405. Adjusting the position of the drilling motor 405 using the servo motor 403 has higher precision, so as to complete the drilling with high precision requirements. At the same time, a micro-adjustment knob 7 is installed on one side of the first fixed plate 1 to adjust the relative position between the fixed plates, further improving the drilling accuracy.

[0025] The sliding module 5 includes a servo cylinder 501 and a slide rail 502. Two sets of servo cylinders 501 are provided, and the two sets of servo cylinders 501 are respectively installed on the upper end surfaces of the first fixed plate 1 and the second fixed plate 2. The upper end surfaces of the first fixed plate 1 and the second fixed plate 2 are provided with slide rails 502. The bottom end surfaces of the second fixed plate 2 and the third fixed plate 3 are provided with sliding grooves 503. One set of servo cylinders 501 is fixedly connected to the second fixed plate 2, and the other set of servo cylinders 501 is fixedly connected to the third fixed plate 3. The second fixed plate 2 and the first fixed plate 1 form a sliding structure through the sliding module 5. The third fixed plate 3 and the second fixed plate 2 form a sliding structure through the sliding module 5. The guide rail 6 and the drilling slide table 401 form a sliding structure.

[0026] The buffer assembly 404 includes a slide rod 4041 and a buffer spring 4042. Both ends of the slide rod 4041 are fixedly connected to the third fixed plate 3. Two sets of extension blocks 4010 are provided. One set of extension blocks 4010 is installed on the outer surface of the slide rod 4041, and one set of extension blocks 4010 and the slide rod 4041 form an up-and-down sliding structure. The other set of extension blocks 4010 is installed on the outer surface of the threaded rod 409, and the extension blocks 4010 and the threaded rod 409 are fixedly threadedly connected. The telescopic end of the drilling cylinder 402 is fixedly connected to the drilling slide table 401, and the end of the drilling cylinder 402 away from the drilling slide table 401 is fixedly connected to the third fixed plate 3. The driving wheel 406 forms a belt drive structure with the driven wheel 408 through the synchronous belt 407. The drilling motor 405 forms a shaft drive structure with the drilling drill bit 4051 through the output shaft.

[0027] Working Principle: When using a modular automatic lifting punching machine, sliding modules 5 are installed between the first fixed plate 1 and the second fixed plate 2, and between the second fixed plate 2 and the third fixed plate 3, to adjust the horizontal movement of the punching mechanism 4 in any direction. The third fixed plate 3 is connected to the punching slide 401 via a guide rail 6 to adjust the position of the punching mechanism 4 longitudinally. A punching cylinder 402 is used to adjust one side of the punching slide 401, and the telescopic end of the punching cylinder 402 is fixedly connected to the punching slide 401. The end of the punching cylinder 402 away from the punching slide 401 is fixedly connected to the third fixed plate 3. Simultaneously, the guide rail 6 and the punching slide 401 form a sliding structure. The punching cylinder 402 controls the up-and-down movement of the punching slide 401, thereby adjusting the position of the punching motor 405 and activating it. When the drilling cylinder 402 adjusts the position of the drilling motor 405, the vibration generated at the moment the drilling cylinder 402 is vented is offset by the buffer component 404 to prevent the drilling bit 4051 from impacting the workpiece. The servo motor 403 is started. Since the driving wheel 406 and the driven wheel 408 form a belt drive structure through the synchronous belt 407, and the extension block 4010 is fixedly threaded to the threaded rod 409, the servo motor 403 rotates, driving the threaded rod 409 to rotate. The servo motor 403 controls the drilling slide 401 to move up and down, thereby adjusting the position of the drilling motor 405. Adjusting the position of the drilling motor 405 using the servo motor 403 has higher precision. At the same time, a micro-adjustment knob 7 is installed on one side of the first fixed plate 1 to further improve the drilling accuracy.
