Description

Technical Field

[0001] This utility model relates to the field of aluminum plate processing technology, and in particular to an aluminum plate processing aluminum mold pressing device. Background Technology

[0002] In the field of high-precision aluminum plate processing, traditional clamping methods are difficult to meet the stringent requirements of modern manufacturing for efficiency and quality. Aluminum is relatively soft and easily deformed. In milling, stamping and other processes, the workpiece often shifts due to vibration or force, which seriously affects the processing accuracy and the yield of finished products. In order to ensure that the aluminum mold and the plate are absolutely stable in the processing process and avoid displacement or vibration, a special aluminum mold clamping device has emerged. Currently, in order to prevent the aluminum sheet from shifting during the aluminum sheet processing, a device is needed to fix the aluminum sheet. During the fixing process, excessive mechanical force may cause irreversible mechanical damage to the aluminum sheet, resulting in damage to the aluminum sheet. In addition, the traditional clamping of aluminum sheets requires manual assistance, which leads to a lot of wasted time in the processing process and thus affects the processing efficiency. Utility Model Content

A movable structure is installed on the processing table. The movable structure includes a control motor fixedly installed on the side wall of the processing table. A bidirectional screw is fixedly installed at the output end of the control motor. Two sliding blocks are threadedly connected to the outer side of the bidirectional screw. A fixed rod is fixedly connected to the side wall of the processing table. Both sliding blocks are slidably connected to the fixed rod. A movable block is slidably connected inside each of the two sliding blocks. A spring is fixedly connected between the movable block and the sliding block.

[0004] Preferably, the movable block is equipped with a clamping structure, the clamping structure including a clamping plate one fixedly connected to the side wall of the movable block, a clamping plate two slidably connected to the side wall of the movable block, a spring two fixedly connected between the clamping plate two and the movable block, a pressing rod fixedly connected to the side wall of the clamping plate two, the pressing rod having two notches on its side wall, two locking blocks slidably connected to the side wall of the movable block, a spring three fixedly connected between each of the two locking blocks and the movable block, a fixing block fixedly connected to the side wall of each of the two locking blocks, a trigger rod slidably connected to the side wall of the movable block, a pressing block fixedly connected to the side wall of the trigger rod, and a spring four fixedly connected between the pressing block and the movable block.

[0005] Preferably, a positioning and clamping structure is installed on the top plate. The positioning and clamping structure includes a bidirectional screw rod rotatably connected to the upper side of the top plate. Two sliding blocks are threadedly connected to the outer side of the bidirectional screw rod. A fixing rod is fixedly connected to the upper side of the top plate. Both sliding blocks are slidably connected to the fixing rod. An electro-hydraulic device is fixedly installed on the lower side of both sliding blocks.

[0006] Preferably, four slide rods are slidably connected to the upper side of the processing table, and buffer plates are fixedly connected to the upper side of each of the four slide rods. Springs are fixedly connected between each of the four buffer plates and the processing table.

[0007] Preferably, the bidirectional screw one and the bidirectional screw two are connected by a pulley assembly.

[0008] Preferably, a pressing block is fixedly connected to the upper end of the pressing rod.

[0009] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, the movable structure enables the two sliders to move simultaneously, thereby ensuring that the aluminum plate remains in the center position, avoiding any deviation of the aluminum plate, and improving the processing accuracy. 2. In this utility model, the clamping structure enables the aluminum plate to be clamped directly by the trigger plate, eliminating the need for manual assistance in clamping, which greatly increases the processing efficiency. Moreover, this clamping method causes less mechanical damage to the aluminum plate, reducing the possibility of damage to the aluminum plate. 3. In this utility model, the positioning and pressing structure ensures that the pressing plate is always above the clamping plate. The pressing of the aluminum plate is completed by pressing the clamping plate and causing the moving block to move downward. This avoids direct contact and pressing of the aluminum plate and reduces damage to the surface of the aluminum plate caused by pressure. Attached Figure Description

Detailed Implementation

[0012] Reference Figures 1-6 An aluminum plate processing aluminum mold clamping device, comprising: A processing table 1 is provided. A placement plate 2 is fixedly connected to the upper side of the processing table 1. Four support rods 3 are fixedly connected to the upper side of the processing table 1. A top plate 4 is fixedly connected to the upper side of the four support rods 3. Four sliding rods 25 are slidably connected to the upper side of the processing table 1. A buffer plate 26 is fixedly connected to the upper side of each of the four sliding rods 25. A spring 5 27 is fixedly connected between each of the four buffer plates 26 and the processing table 1. During the pressing process, the springs provide elastic support to prevent the aluminum plate from deforming due to excessive pressing. The springs also provide support for the periphery of the aluminum plate. A movable structure is installed on the machining table 1. The movable structure includes a control motor 5 fixedly installed on the side wall of the machining table 1. A bidirectional screw 6 is fixedly installed at the output end of the control motor 5. Two sliding blocks 7 are threadedly connected to the outer side of the bidirectional screw 6. The bidirectional screw 6 is composed of two ball screws with opposite thread directions. The ball screws have high precision and will not have large deviations. By rotating, the two sliding blocks 7 can slide inward or outward simultaneously on the outer side of the bidirectional screw 6, so that the two sliding blocks 7 are synchronized. A fixed rod 8 is fixedly connected to the side wall of the machining table 1. Both sliding blocks 7 are slidably connected to the fixed rod 8. The fixed rod 8 has a limiting function, so that the two sliding blocks 7 can move linearly. A moving block 9 is slidably connected inside each of the two sliding blocks 7. A spring 10 is fixedly connected between the moving block 9 and the sliding block 7.

[0013] The movable block 9 is equipped with a clamping structure, which includes a clamping plate 11 fixedly connected to the side wall of the movable block 9, a clamping plate 12 slidably connected to the side wall of the movable block 9, a spring 13 fixedly connected between the clamping plate 12 and the movable block 9, a pressing rod 14 fixedly connected to the side wall of the clamping plate 12, and a pressing block fixedly connected to the upper end of the pressing rod 14. The pressing block increases the contact area, making it easier for the operator to apply force, improving operating comfort and safety, and reducing the possibility of misoperation. The side wall of the pressing rod 14 has two notches, and the side wall of the movable block 9 has two locking blocks 15 slidably connected. The two locking blocks 15 match the two notches and can be inserted into the notches to fix the pressing rod 14. A spring 16 is fixedly connected between each of the two locking blocks 15 and the movable block 9. A fixing block 17 is fixedly connected to the side wall of each of the two locking blocks 15. The side wall of the fixing block 17 has an inclined sliding surface. A trigger rod 18 is connected to the moving block 9. A pressing block 19 is fixedly connected to the side wall of the trigger rod 18. A spring 20 is fixedly connected between the pressing block 19 and the moving block 9. When the moving block 9 moves with the sliding block 7, the aluminum plate will press the trigger rod 18. The trigger rod 18 slides into the moving block 9, thereby pressing the two fixed blocks 17 through the pressing block 19. This causes the locking block 15 to move outward on both sides and move out of the notch. After it moves out, the pressing rod 14 is unrestricted. At this time, the clamping plate 12 moves upward by the elastic force of the spring 13, thereby driving the aluminum plate to move upward and clamping the aluminum plate with the clamping plate 11. When it is necessary to release the clamping, the pressing block can press the pressing rod 14 downward to move the clamping plate 12 downward. After moving to the corresponding position, the locking block 15 is reinserted into the notch by the elastic force of the spring 3 16 to fix the pressing rod 14.

[0014] A positioning and clamping structure is installed on the top plate 4. This structure includes a bidirectional screw 21 rotatably connected to the upper side of the top plate 4. The bidirectional screw 6 and the bidirectional screw 21 are connected via a pulley assembly 28, which consists of two pulleys and a belt. The bidirectional screw 6 and the bidirectional screw 21 are identical; therefore, when the bidirectional screw 6 rotates, the bidirectional screw 21 also rotates. Two sliding blocks 22 are threaded onto the outer side of the bidirectional screw 21. The sliding blocks 22 slide the same distance as the sliding block 7. A fixing rod 23 is fixedly connected to the upper side of the top plate 4. Both sliding blocks 22 are slidably connected to the fixed rod 23. Both sliding blocks 22 are fixedly mounted with an electro-hydraulic device 29 on their lower sides. The electro-hydraulic device 29 is a device that converts electrical energy into hydraulic energy and then outputs mechanical work through hydraulic actuators. It consists of an electric motor, a hydraulic pump, an oil tank, and a control valve. It can extend the distance of the output end and has a self-locking function. This is existing technology and will not be described in detail. The output end of the electro-hydraulic device 29 is fixedly mounted with a pressure plate 24. Because the movement distance is the same, the pressure plate 24 is always kept above the clamping plate 11.

[0015] In this invention, firstly, the worker places the aluminum plate to be pressed on the upper side of the placement plate 2. At this time, the control motor 5 is started to rotate the bidirectional screw 6. The rotation of the bidirectional screw 6 causes the two sliding blocks 7 to move inward simultaneously. During the movement, the aluminum plate presses the trigger rod 18, causing the trigger rod 18 to move inward into the moving block 9. During the movement, the pressing block 19 can press the two fixing blocks 17, causing the two locking blocks 15 to move out of the notch of the pressing rod 14. At this time, the pressing rod 14 is unrestricted, allowing the clamping plate 12 to move upward by the spring 13, thereby lifting the aluminum plate and cooperating with the fixedly connected clamp. Plate 11 clamps the aluminum plate. When the bidirectional screw 6 rotates, it can also drive the bidirectional screw 21 to rotate through the pulley assembly 28. This causes the two sliding blocks 22 to move the same distance as the sliding block 7 because the bidirectional screw 6 and the bidirectional screw 21 are exactly the same. This ensures that the pressure plate 24, which is fixedly connected to the output end of the electro-hydraulic device 29, is always above the clamping plate 11. By activating the electro-hydraulic device 29, the pressure plate 24 presses the clamping plate 11, causing the moving block 9 to move downward until the aluminum plate contacts the placement plate 2, thus completing the clamping work of the aluminum plate.
