Description

Technical Field

[0001] This utility model relates to the field of CNC machining platform technology, specifically to a CNC machining platform for aluminum alloy die castings. Background Technology

[0002] A CNC machining platform is an automated manufacturing system based on computer numerical control technology. It precisely controls the movement trajectory and machining parameters of machine tool cutting tools through pre-programmed instructions, enabling efficient and high-precision cutting, drilling, milling, or turning of workpieces such as metals, plastics, and composite materials.

[0003] In traditional hydraulic systems, the synchronous movement of the hydraulic telescopic rod can easily cause the workpiece to be subjected to bidirectional forces. When the thrust of the hydraulic telescopic rod reaches or exceeds a certain threshold, this force will cause the workpiece to undergo wedge-shaped displacement, resulting in a change in the workpiece's position during processing, which in turn affects the processing accuracy. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides a CNC machining platform for aluminum alloy die castings, which solves the problem mentioned in the background art that when the thrust of the hydraulic telescopic rod reaches or exceeds a certain threshold, this force will cause the workpiece to undergo wedge-shaped displacement, resulting in a change in the position of the workpiece during the machining process, thereby affecting the machining accuracy.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a CNC machining platform for aluminum alloy die castings, comprising:

[0007] A processing table, wherein a side plate is installed on the upper surface of the processing table, and a grinding device is provided on the surface of the side plate;

[0008] A first motor is installed in a mounting slot on the upper surface of the processing table. A first lead screw is coaxially mounted on the rotor of the first motor. A movable table is screwed onto the surface of the first lead screw. Hydraulic telescopic rods are installed on both the front and back of the movable table.

[0009] A clamping plate is provided at the output end of the hydraulic telescopic rod. Each output end of the hydraulic telescopic rod is equipped with a ball joint bearing. Each hydraulic telescopic rod is connected to the surface of the clamping plate through the ball joint bearing. Each surface of the clamping plate is equipped with a pressure sensor. Each pressing surface of the clamping plate is provided with a pressing plate. Each of the four corners of the pressing plate is equipped with a plug-in block, which is inserted into the surface of the clamping plate.

[0010] A pressure reducing valve is installed at the oil cylinder of the hydraulic telescopic rod. An actuator is installed on the surface of the pressure reducing valve, and a controller is installed on the surface of the actuator.

[0011] Preferably, a second motor is installed in the middle of the surface of the side plate, and a second lead screw is coaxially mounted on the rotor of the second motor. A movable seat is screwed onto the surface of the second lead screw. Starting the second motor can drive the second lead screw to rotate, thereby driving the movable seat to move.

[0012] Preferably, limit rods are installed on both the upper and lower parts of the surface of the side plate, and the limit rods penetrate the surface of the movable seat, so that the movable seat can move stably.

[0013] Preferably, a third motor is mounted on the upper surface of the movable seat, and a third lead screw is coaxially mounted on the rotor of the third motor. The third lead screw is screwed to the grinding device. Starting the third motor can drive the third lead screw to rotate, thereby driving the grinding device to move up and down.

[0014] Preferably, the grinding device has sliders installed on both the front and back sides, and slide rails are installed on the surface of the movable seat at positions corresponding to the sliders. The sliders are embedded in the slide rails, enabling the grinding device to move vertically.

[0015] Preferably, limit blocks are installed on both the front and back of the moving stage, and limit grooves are formed on the inner wall of the mounting groove of the processing table. The limit blocks are inserted into the interior of the limit grooves, so that the moving stage can move linearly. Beneficial effects

[0016] Compared with the prior art, this utility model provides a CNC machining platform for aluminum alloy die castings, which has the following advantages:

[0017] This CNC machining platform for aluminum alloy die castings uses pressure sensors on the clamping plate to detect pressure changes and transmit the signals to the controller. After analyzing the signals, the controller controls the actuator to adjust the pressure reducing valve to reduce the output pressure of the hydraulic telescopic rod, preventing excessive thrust from being applied to the workpiece. At the same time, the ball joint bearing allows the clamping plate to adaptively adjust its angle according to the force, reducing wedge displacement caused by uneven local force. In addition, the structure of the extrusion plate connected to the clamping plate through the plug block can provide a certain buffer when the force is too large. Through the synergistic effect of these structural processes, the position of the workpiece can be effectively prevented from changing due to force during the machining process, thereby improving machining 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] This utility model provides a technical solution: a CNC machining platform for aluminum alloy die-casting parts. Please refer to [link / reference]. Figure 1 ,include:

[0025] A processing table 1 is provided with a side plate 2 on its upper surface and a grinding device 3 on the surface of the side plate 2.

[0026] The first motor 4 is installed in the mounting groove on the upper surface of the processing table 1. The rotor of the first motor 4 is coaxially mounted with the first lead screw 5. The surface of the first lead screw 5 is screwed with a movable table 6. The front and back of the movable table 6 are both equipped with hydraulic telescopic rods 7.

All hydraulic telescopic rods 7 are connected to the surface of the clamping plate 8 through ball joint bearings 71. All surfaces of the clamping plate 8 are equipped with pressure sensors 9. All pressing surfaces of the clamping plate 8 are provided with pressing plates 10. All four corners of the surface of the pressing plate 10 are equipped with plug-in blocks 11. All plug-in blocks 11 are inserted into the surface of the clamping plate 8.

[0028] Pressure reducing valve 12 is installed at the oil cylinder of hydraulic telescopic rod 7. Actuator 13 is installed on the surface of pressure reducing valve 12, and controller 14 is installed on the surface of actuator 13.

[0029] Starting the first motor 4 can drive the first lead screw 5 to rotate, thereby driving the moving table 6 to move, and thus moving the aluminum alloy die-casting part to the designated position;

[0030] Activating the hydraulic telescopic rod 7 can drive the clamping plate 8 to clamp and process the aluminum alloy die casting. The extrusion plate 10 will transmit the extrusion force to the pressure sensor 9.

[0031] When the thrust of the hydraulic telescopic rod 7 reaches or exceeds the set threshold, the pressure sensor 9 on the clamping plate 8 senses the pressure change and transmits the signal to the controller 14. After analyzing the signal, the controller 14 controls the actuator 13 to act, thereby adjusting the pressure reducing valve 12 to reduce the output pressure of the hydraulic telescopic rod 7, avoiding excessive thrust applied to the workpiece. At the same time, the ball joint bearing 71 allows the clamping plate 8 to adaptively adjust its angle according to the force, reducing wedge displacement caused by uneven local force. In addition, the structure of the extrusion plate 10 connected to the clamping plate 8 through the plug block 11 can provide a certain buffer when the force is too large. Through the synergistic effect of these structural processes, the positional change of the workpiece due to force problems during processing can be effectively prevented, thereby improving the processing accuracy.

[0032] Please see Figure 1 A second motor 15 is installed in the middle of the surface of the side plate 2. A second lead screw 16 is coaxially installed on the rotor of the second motor 15. A movable seat 17 is screwed onto the surface of the second lead screw 16. Starting the second motor 15 can drive the second lead screw 16 to rotate, thereby driving the movable seat 17 to move.

[0033] Limiting rods 18 are installed on both the upper and lower parts of the surface of the side plate 2. The limiting rods 18 penetrate the surface of the movable seat 17, so that the movable seat 17 can move stably.

[0034] Please see Figure 4 A third motor 19 is mounted on the upper surface of the movable seat 17. A third lead screw 20 is coaxially mounted on the rotor of the third motor 19. The third lead screw 20 is screwed to the grinding device 3. Starting the third motor 19 can drive the third lead screw 20 to rotate, thereby driving the grinding device 3 to move up and down.

[0035] Sliders 21 are installed on both the front and back of the grinding device 3. Slide rails 22 are installed on the surface of the moving base 17 at the corresponding positions of the slides 21. The slides 21 are embedded in the slide rails 22, so that the grinding device 3 can move vertically.

[0036] Please see Figure 1 Limit blocks 23 are installed on both the front and back of the moving stage 6. Please refer to [link / reference]. Figure 2 The inner wall of the mounting slot of the processing table 1 is provided with a limit groove 24, and the limit block 23 is inserted into the inside of the limit groove 24, so that the moving table 6 can move linearly.

[0037] During operation, the following steps are taken: The first motor 4 is activated, driving the first lead screw 5 to rotate, causing the moving table 6 to move linearly under the cooperation of the limiting block 23 and the limiting groove 24, moving the aluminum alloy die-casting to the designated position; the hydraulic telescopic rod 7 is activated, which drives the clamping plate 8 to clamp the workpiece through the ball joint bearing 71, and the extrusion plate 10 transmits the extrusion force to the pressure sensor 9. When the thrust reaches the threshold, the pressure sensor 9 sends a signal to the controller 14, and the controller 14 controls the actuator 13 to adjust the pressure reducing valve 12 to reduce the pressure; the second motor 15 is activated, driving the second lead screw 16 to rotate, causing the moving seat 17 to move stably under the action of the limiting rod 18; the third motor 19 is activated, driving the third lead screw 20 to rotate, causing the grinding device 3 to rise and fall vertically under the cooperation of the slider 21 and the slide rail 22, thereby completing the processing of the aluminum alloy die-casting, preventing the workpiece from changing position due to force issues, and improving processing accuracy.
