Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a milling machine tooling with an adaptively adjustable machining angle. Background Technology

[0002] A milling machine is a machine tool mainly used for metal processing. It uses a rotating multi-bladed cutting tool to cut workpieces and can process parts with various complex shapes. A milling machine fixture that can adaptively adjust the machining angle is an auxiliary device used in milling machine processing, which is designed to improve the flexibility and accuracy of milling machine processing.

[0003] A search revealed Chinese Patent Publication No. CN106424862A, which discloses an integrated machining tool for processing valve bodies. The tool includes a gantry milling machine, a base, and a reciprocating worktable on the base. A detachable tooling fixture is mounted on the worktable. A first cutting device is positioned above the tooling fixture, and a second cutting device is positioned beside the first clamping fixture. This invention clamps the valve body using the first clamping fixture and processes the side end face of the valve body using the second cutting device beside the first clamping fixture. The valve body is then placed obliquely on the tooling fixture, and the inner oblique surface of the valve body is processed using the first cutting device. The operation is simple and the clamping is stable, improving work efficiency and processing speed. However, during the engraving process, the equipment generates flying debris, which can splash onto the operator's body, face, and eyes, causing injury. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a milling machine fixture with an adaptively adjustable machining angle, which aims to improve the problem that when the equipment is used for reprocessing and engraving, it will generate flying debris, which can fly onto the operator's body, face and eyes, thus causing injury to the operator.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a milling machine fixture with adaptively adjustable machining angle, comprising a machine body, an engraving head fixedly connected to the top of the machine body, an elongated support plate fixedly connected to the bottom of the engraving head, a plurality of hollow blocks fixedly connected at equal intervals to the bottom of the elongated support plate, spring coils rotatably connected inside the hollow blocks, elongated short plates fixedly connected to the left and right sides of the bottom of the elongated support plate, elongated coils rotatably connected to adjacent sides of the outer wall of the elongated short plates, an elongated inner slider plate fixedly connected to the bottom of the elongated short plates, and an elongated inner slider plate fixedly connected to the front side of the engraving head at equal intervals. The machine body is equipped with multiple L-shaped support plates. A threaded rod is rotatably connected to the top of each L-shaped support plate. A movable plate is threadedly connected to the outer wall of the threaded rod. The top of the movable plate is fixedly connected to the bottom of both the long winding strip and the spring winding strip. A fixed long rod is rotatably connected to the middle of the outer wall of each L-shaped support plate. Multiple bevel gears are fixedly connected at equal intervals to the outer wall of the fixed long rod. A bevel gear is fixedly connected to the bottom of the threaded rod. The bevel gears mesh with the bevel gears. An adjustment mechanism is installed on the top of the machine body. The adjustment mechanism is used to adjust the angle of the fixed workpiece to adapt to different processing needs.

[0006] The above technical solution works as follows: by rotating the fixed long rod, multiple bevel gears on the outer wall rotate accordingly. Since bevel gear one and bevel gear two are meshed and connected, and bevel gear one is fixed at the bottom end of the threaded rod, the rotation of bevel gear two will drive bevel gear one to rotate, which in turn will cause the threaded rod to rotate. When the threaded rod rotates, it will drive the moving plate connected to the threaded rod on the outer wall to move up and down, thereby pulling the long roll and spring roll to unfold, covering the engraving head and blocking the flying debris generated during the engraving process. After the processing is completed, the fixed long rod is rotated in the opposite direction, causing the threaded rod to rotate in the opposite direction and the moving plate to move upward. At this time, the spring roll retracts back into the hollow cube using its own elasticity, and the long roll also retracts accordingly, making it convenient for the next use.

[0007] As a further description of the above technical solution: The adjustment mechanism includes a dual-axis rotary platform, which is mounted on the top of the machine body. A pressure sensor is installed on the front side of the top of the dual-axis rotary platform. Multiple flexible grippers are equidistantly installed on the top of the dual-axis rotary platform. An embedded controller is fixedly connected to the front side of the upper middle part of the outer wall of the engraving head. An angle sensor is fixedly connected to the front side of the lower middle part of the outer wall of the engraving head. A central controller is fixedly connected to the right side of the outer wall of the machine body.

[0008] The above technical solution involves placing the workpiece on a dual-axis rotary platform when processing is required. Multiple flexible grippers on the top of the platform clamp the workpiece. During clamping, pressure sensors continuously monitor the pressure applied by the grippers. When the pressure reaches a suitable value, the sensors send a signal to the embedded controller or central controller to ensure the grippers automatically adjust their clamping force according to the workpiece's shape, preventing deformation due to excessive force. Before processing, the operator presets processing parameters, such as the required processing angle, in the central controller. Simultaneously, an angle sensor installed on the lower front side of the engraving head monitors the angle between the engraving head and the workpiece in real time and sends this data back to the central controller. The central controller then integrates the received real-time angle data with... The preset processing parameters are compared and analyzed. Based on the results of the comparison and analysis, the central controller sends instructions to the embedded controller. After receiving the instructions, the embedded controller controls the high-precision servo motors on the dual-axis rotary platform. The dual-axis rotary platform has horizontal and vertical axes. Driven by the servo motors, it can rotate in both horizontal and vertical directions, thereby adjusting the angle of the workpiece. During the rotation and angle adjustment process of the dual-axis rotary platform, the angle sensor continuously monitors the angle change of the workpiece and feeds back the latest angle data to the central controller. The central controller continuously compares the feedback data with the preset parameters. If a deviation is found, it will promptly send a correction instruction to the embedded controller. The embedded controller then readjusts the servo motors, enabling the dual-axis rotary platform to further fine-tune the angle, achieving adaptive compensation and ensuring that the workpiece reaches the preset precise processing angle.

[0009] As a further description of the above technical solution: A circular handle is fixedly connected to the right end of the outer wall of the fixed long rod, and a protective sleeve is fixedly connected to the outer wall of the circular handle.

[0010] Through the above technical solution, the circular handle facilitates the operation of workers to rotate and fix the long rod.

[0011] As a further description of the above technical solution: A light bulb is mounted on the top of the engraving head.

[0012] The above technical solution allows the light bulb installed on top of the carving head to provide auxiliary lighting in low-light environments.

[0013] As a further description of the above technical solution: A screw is threadedly connected to the right side of the outer wall of the machine body, and a hook is threadedly connected to the outer wall of the screw.

[0014] The above technical solution allows for the convenient hanging of tools used daily for cleaning via hooks on the right side of the outer wall of the machine.

[0015] As a further description of the above technical solution: A screw is threadedly connected to the left side of the outer wall of the machine body, and a warning sign is threadedly connected to the outer wall of the screw.

[0016] Through the above technical solution, the warning sign on the left side of the machine body can remind staff of routine precautions when operating the equipment, thereby reducing the probability of accidents.

[0017] As a further description of the above technical solution: A hollow box is fixedly connected to the left side of the middle part of the outer wall of the machine body, and a drawer is slidably connected inside the hollow box.

[0018] The above technical solution allows for the convenient storage of tools used daily and for maintenance through sliding drawers inside the hollow box.

[0019] As a further description of the above technical solution: A handle is fixedly connected to the left side of the outer wall of the drawer, and an anti-slip sleeve is fixedly connected to the outer wall of the handle.

[0020] The above technical solution provides a handle fixedly connected to the left side of the outer wall of the drawer, which facilitates the opening and closing of the drawer for use by staff.

[0021] This utility model has the following beneficial effects: 1. In this utility model, the long rod is rotated to drive the second bevel gear to rotate. When the second bevel gear rotates, it will mesh with the first bevel gear at the bottom of the threaded rod. As a result, the threaded rod rotates, which in turn causes the moving plate to move up and down along the threaded rod, pulling the winding tape and spring winding tape to cover the engraving head. This avoids the problem that flying debris will be generated during the reprocessing and engraving of the equipment, and that the flying debris will fly onto the operator's body, face and eyes, thus causing injury to the operator.

[0022] 2. In this utility model, when a workpiece needs to be processed, it is placed on a dual-axis rotary platform. Multiple flexible grippers on the top of the dual-axis rotary platform will clamp the workpiece. During the clamping process, pressure sensors will detect the pressure applied to the workpiece by the flexible grippers in real time. When the pressure reaches a suitable value, it ensures that the flexible grippers automatically adjust the clamping force according to the shape of the workpiece. In this way, by adjusting the angle, the loading, unloading and positioning time is reduced, making the processing process smoother and significantly improving the processing efficiency.

[0029] Working principle: By rotating the fixed long rod 23, multiple bevel gears 22 on the outer wall are driven to rotate. Since bevel gear 19 meshes with bevel gear 22 and bevel gear 19 is fixed at the bottom of the threaded rod 26, the rotation of bevel gear 22 will drive bevel gear 19 to rotate, which in turn will cause the threaded rod 26 to rotate. When the threaded rod 26 rotates, it will drive the moving plate 25 connected to the threaded wall to move up and down on the outer wall of the threaded rod 26, thereby pulling the long winding belt 15 and the spring winding belt 14 to unfold, covering the engraving head 5 and blocking the flying debris generated during the engraving process. After the processing is completed, the fixed long rod 23 is rotated in the opposite direction, causing the threaded rod 26 to rotate in the opposite direction and the moving plate 25 to move upward. At this time, the spring winding belt 14 retracts back into the hollow square 13 using its own elasticity, and the long winding belt 15 also retracts accordingly, making it convenient for the next use. This avoids the problem that flying debris will be generated during the reprocessing engraving of the equipment, and that the flying debris will fly onto the operator's body, face and eyes, thus causing injury to the operator. When processing is required, the workpiece is placed on the dual-axis rotary platform 201. Multiple flexible grippers 203 on the top of the dual-axis rotary platform 201 clamp the workpiece. During clamping, pressure sensors 202 detect the pressure applied to the workpiece by the flexible grippers 203 in real time. When the pressure reaches a suitable value, the pressure sensors 202 send a signal to the embedded controller 205 or the central controller 206 to ensure that the flexible grippers 203 automatically adjust the clamping force according to the workpiece shape, avoiding workpiece deformation due to excessive clamping force. Before processing begins, the operator presets processing parameters in the central controller 206 according to processing requirements, such as the required processing angle. Simultaneously, the angle sensor 204 installed on the lower front side of the outer wall of the engraving head 5 monitors the current angle information between the engraving head 5 and the workpiece in real time and sends this data back to the central controller 206. The central controller 206 compares and analyzes the received real-time angle data with the preset processing parameters. Based on the analysis results, instructions are sent to the embedded controller 205. Upon receiving the instructions, the embedded controller 205 controls the high-precision servo motors on the dual-axis rotary platform 201 to operate. The dual-axis rotary platform 201 has horizontal and vertical axes. Driven by the servo motors, it can rotate in both horizontal and vertical directions, thereby adjusting the angle of the workpiece. During the rotation and angle adjustment process of the dual-axis rotary platform 201, the angle sensor 204 continuously monitors the angle changes of the workpiece and feeds back the latest angle data to the central controller 206. The central controller 206 continuously compares the feedback data with preset parameters. If a deviation is found, it will promptly send a correction instruction to the embedded controller 205. The embedded controller 205 then adjusts the servo motors again, causing the dual-axis rotary platform 201 to further fine-tune the angle, achieving adaptive compensation and ensuring that the workpiece reaches the preset precise processing angle. This angle adjustment method reduces loading, unloading, and positioning time, making the processing process smoother and significantly improving processing efficiency.
