Description

Technical Field

[0001] This utility model relates to the field of machining, and in particular to an integrated milling and drilling device. Background Technology

[0002] In the field of machining, the milling and drilling processes for template-type workpieces traditionally employ a "step-by-step processing and multi-equipment transfer" model. This involves first milling the workpiece around its perimeter using a milling machine, then manually transferring it to a drilling machine to machine the holes. This model results in lengthy workpiece transfers, equipment adjustments, and repositioning between processes, significantly increasing the overall processing cycle and reducing efficiency during mass production. Furthermore, the need for re-clamping and repositioning workpieces between different machines, coupled with repeated positioning, can lead to datum deviations, reducing the relative accuracy of milling and drilling and failing to meet the demands of high-precision machining. Utility Model Content

[0003] This application provides an integrated milling and drilling device, which solves the technical problems of existing milling and drilling processes for template-type workpieces, which are characterized by long operation time, significantly increased overall processing cycle during mass production, low processing efficiency, and the need for re-clamping and positioning of workpieces when transferred between different devices. Multiple positioning can easily cause reference deviations, resulting in a decrease in the relative accuracy of milling and drilling, making it difficult to meet the requirements of high-precision processing.

[0004] The technical solutions adopted in the embodiments of this application are as follows.

[0010] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages: By integrating the worktable, milling mechanism, and drilling device into a single unit, milling and drilling functions can be combined into one device. This allows for multi-process machining of a single workpiece clamping, completely eliminating the time spent transferring workpieces between different devices and repeatedly positioning them, a common practice in traditional methods. Simultaneously, the milling and drilling mechanisms can perform processing on different workpieces concurrently, significantly improving overall processing efficiency in mass production scenarios. To address the issue of large machining accuracy errors, the device utilizes a floating pin three-point positioning structure in the suction cup rotation system, working in conjunction with the vacuum suction cup. This ensures precise alignment of the workpiece's reference point with the equipment's machining reference point during the workpiece clamping stage. Furthermore, the workpiece remains fixed on either the first or second suction cup rotation system throughout the machining process, eliminating the need for transfer and fundamentally avoiding reference deviations caused by multiple positioning steps. This significantly improves the relative machining accuracy of milling and drilling. To address the issues of high labor costs and intensity, the device significantly reduces manual intervention through automated sliding of the sliding components, automatic rotation of the suction cup system, and automated processing of the milling and drilling components.

Regarding the issue of large space requirements, the device integrates the milling and drilling mechanisms onto a single workbench. Compared to traditional two separate devices, this significantly reduces the overall footprint, effectively improving workshop space utilization and better adapting to the layout needs of limited production spaces.

[0018] This application provides an integrated milling and drilling device, which solves the technical problems of existing milling and drilling processes for template-type workpieces, which are characterized by long operation time, significantly increased overall processing cycle during mass production, low processing efficiency, and the need for re-clamping and positioning of workpieces when transferred between different devices. Multiple positioning can easily cause reference deviations, resulting in a decrease in the relative accuracy of milling and drilling, making it difficult to meet the requirements of high-precision processing.

[0019] The technical solution in this application is to solve the above problems, and the overall approach is as follows: To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0020] An integrated milling and drilling device, such as Figures 1-6 As shown, the device includes a basic support structure based on a workbench 1. The bottom of the workbench 1 is equipped with a metal support platform and a foot pedal operating platform, which not only provides stable support for the overall device, but also facilitates the operator to perform workpiece clamping operations at close range. The core functional components of the device are a milling mechanism 2 and a drilling device 3, which are symmetrically arranged on the left and right sides of the workbench 1, respectively. The milling mechanism 2 consists of a sliding component 21, a milling component 22, and a first suction cup rotation system 23. The sliding component 21 is directly fixed on the worktable 1, the milling component 22 is symmetrically distributed on both sides of the sliding component 21, and the first suction cup rotation system 23 is installed on the sliding component 21. Together, they realize the automatic positioning, sliding, and milling of the workpiece around its perimeter. The drilling device 3 includes a support block 31, a drilling component 32, and a second suction cup rotation system 33. The support block 31 is fixed on the worktable 1, and the drilling component 32 and the second suction cup rotation system 33 are both assembled on the support block 31. Together, they complete the automatic rotation of the workpiece and multi-position drilling. The overall structure is modularly designed to achieve the integration and automation of milling and drilling functions.

[0021] The sliding assembly 21 consists of a base 211, a slider 212, a first lead screw 213, a first slide rail 214, and a first motor 215. The base 211 is fixed on the worktable 1. The first lead screw 213 is rotatably connected to both ends of the base 211 via bearings. The output shaft of the first motor 215 is connected to the first lead screw 213 via a coupling. The first slide rail 214 is parallel to the first lead screw 213 and fixed on the base 211. The bottom of the slider 212 has a groove that matches the first slide rail 214, and the middle has a threaded hole that meshes with the first lead screw 213, forming an automated motion structure of "motor drive - lead screw transmission - slider sliding". This structure can drive the first suction cup rotation system 23 and the workpiece to move along the direction of the first slide rail 214, and cooperate with the milling assembly 2. 2. Complete the milling process; the milling assembly 22 consists of a milling cutter 221, a second motor 222, a sliding plate 223, a second slide rail 224, a support base 225, a second lead screw 226, and a third motor 227. The support base 225 is symmetrically fixed on both sides of the sliding assembly 21. The second slide rail 224 is fixed to the support base 225 perpendicular to the first slide rail 214. The second lead screw 226 is rotatably connected to the support base 225 and is driven by the third motor 227. The sliding plate 223 is slidably connected to the second slide rail 224 and threadedly connected to the second lead screw 226. The second motor 222 is mounted on the sliding plate 223. The milling cutter 221 is coaxially fixed on the output shaft of the second motor 222. The third motor 227 drives the sliding plate 223 to move along the second slide rail 224. The adjustable end mill 221 has a distance between itself and the workpiece. The second motor 222 drives the end mill 221 to rotate at high speed, completing the edge milling of the workpiece. The drilling assembly 32 consists of a drill bit 321, a fourth motor 322, a moving plate 323, a third slide rail 324, a fixed base 325, a third lead screw 326, and a fifth motor 327. The fixed base 325 is fixed to the support block 31. The third slide rail 324 and the third lead screw 326 are arranged parallel to each other on the fixed base 325. The fifth motor 327 is connected to the third lead screw 326 via a transmission connection. The moving plate 323 is slidably connected to the third slide rail 324 and threadedly connected to the third lead screw 326. The fourth motor 322 is mounted on the moving plate 323. The drill bit 321 is fixed to the output shaft of the fourth motor 322. The fifth motor 327 drives the moving plate 323 to move the adjustable drill bit 321 to a different position. The fourth motor 322 drives the drill bit 321 to rotate, completing the drilling of the workpiece. The suction cup rotation system 23 / 33 consists of an electric turntable, a vacuum suction cup, and a floating pin positioning structure. The first suction cup rotation system 23 is fixed on the slider 212 of the sliding component 21, and the second suction cup rotation system 33 is fixed on the support block 31. The vacuum suction cup is installed at the output end of the electric turntable. The floating pin positioning structure is set around the suction cup and corresponds to the four corner protection installation points of the workpiece. It adopts three-point contact positioning. The vacuum suction cup can realize the quick clamping of the workpiece. The floating pin three-point positioning can ensure the accuracy of the workpiece datum. The electric turntable can drive the workpiece to rotate 90° to meet the multi-face processing requirements.

[0022] Operating procedures: 1. Workpiece clamping The operator approaches the equipment via the foot platform of workbench 1, places the template workpiece to be processed on the vacuum suction cups of the first suction cup rotation system 23 and the second suction cup rotation system 33 respectively, activates the floating pin positioning structure, aligns the workpiece reference through the 3-point contact positioning at the 4 corner protection installation points, and then activates the vacuum suction cup to generate negative pressure to clamp the workpiece, thus completing the clamping.

[0023] 2. Milling process The first motor 215 is started, driving the slider 212 to move along the first slide rail 214 towards the milling assembly 22. Simultaneously, the second motor 222 is started, driving the milling cutter 221 to rotate at high speed. The third motor 227 adjusts the milling cutter 221 to the cutting position. As the workpiece moves with the slider, the milling cutters on both sides complete the first set of relative edge milling. The sliding assembly 21 stops moving, and the electric turntable of the first suction cup rotation system 23 is started, driving the workpiece to rotate 90° clockwise and then locking. The first motor 215 is started again, driving the slider 212 to move in the opposite direction, and the milling cutters on both sides complete the second set of relative edge milling, ending the 4-sided milling. The second motor 222 stops, the third motor 227 drives the milling cutter 221 to reset, and the first motor 215 drives the slider 212 back to its initial position.

[0024] 3. Drilling process The fifth motor 327 is activated, driving the moving plate 323 to move along the third slide rail 324 towards the workpiece. Simultaneously, the fourth motor 322 is activated, rotating the drill bit 321. After the moving plate reaches its position, drilling at the first position is completed, and then the plate is reset. The electric turntable of the second suction cup rotation system 33 is activated, rotating the workpiece 90° clockwise and locking it. This process is repeated to complete drilling at that angle. The "rotate 90° - drill" cycle is repeated three times to complete machining of all holes at the four angles. The fourth motor 322 stops, and the fifth motor 327 drives the moving plate 323 to reset.

[0025] 4. Workpiece removal and circulation After shutting down the vacuum suction cup, the operator removes the finished workpiece, repositions the workpiece to be processed, and begins the next batch of processing.

[0026] Beneficial effects By integrating the worktable 1, milling mechanism 2, and drilling device 3 into a single unit, milling and drilling functions are combined into one device. This allows for multi-process machining of a workpiece in a single clamping operation, completely eliminating the time spent transferring workpieces between different devices and repeatedly positioning them, a common practice in traditional methods. Simultaneously, the milling mechanism 2 and drilling device 3 can perform processing operations on different workpieces concurrently, significantly improving overall processing efficiency in mass production scenarios. Regarding the issue of large machining accuracy errors, the device utilizes a floating pin three-point positioning structure in the suction cup rotation system 23 / 33, working in conjunction with the vacuum suction cup, to ensure precise alignment of the workpiece's reference point with the equipment's machining reference point during the workpiece clamping stage. Furthermore, the workpiece remains fixed on either the first suction cup rotation system 23 or the second suction cup rotation system 33 throughout the machining process, eliminating the need for transfer and fundamentally avoiding reference deviations caused by multiple positioning operations, thus significantly improving the relative machining accuracy of milling and drilling. To address the issues of high labor costs and intensity, the device significantly reduces manual intervention through automated sliding of the sliding assembly 21, automatic rotation of the suction cup rotation system 23 / 33, and automated processing of the milling assembly 22 and drilling assembly 32. Only one operator is required to monitor multiple devices and handle workpiece loading and unloading. Furthermore, the foot platform on the workbench 1 optimizes the operating distance, further reducing the labor intensity of manual handling and operation, and minimizing the risk of workpiece damage during manual transfer. Regarding the issue of large space requirements, the device integrates the milling mechanism 2 and the drilling device 3 onto the same workbench 1. Compared to traditional two separate devices, this significantly reduces the overall footprint, effectively improving workshop space utilization and better adapting to the layout requirements of limited production spaces.
