[0019] This application discloses a hydraulic clamping device for aluminum alloy machining. (Refer to...) Figure 1 , Figure 3 , Figure 4 The system includes a support plate 1, which supports the aluminum alloy for subsequent processing. The support plate 1 is welded or detachably fixed to the processing table by bolts, so that the processing table supports the support plate 1, thereby supporting the aluminum alloy on the support plate 1 and enabling subsequent processing of the aluminum alloy.

[0020] Reference Figure 1 , Figure 3 , Figure 4A hydraulic telescopic rod 2 is detachably and fixedly connected to the lower end face of the support plate 1 by bolts, so that the hydraulic telescopic rod 2 and the support plate 1 are connected together to form a whole, and the support plate 1 supports and limits the hydraulic telescopic rod 2. A left toothed plate 3 is detachably and fixedly connected to the telescopic end of the hydraulic telescopic rod 2 by bolts, so that the left toothed plate 3 and the telescopic end of the hydraulic telescopic rod 2 are connected together to form a whole, and the telescopic movement of the hydraulic telescopic rod 2 drives the left toothed plate 3 to move. A drive gear 6 is connected to the support plate 1, so that the support plate 1 and the drive gear 6 are connected together, and the drive gear 6 can rotate relative to the support plate 1. Specifically, a support bearing 4 is detachably and fixedly connected to the support plate 1 by bolts, so that the support bearing 4 and the support plate 1 are connected together to form a whole, and the support plate 1 supports and limits the support bearing 4. A rotating shaft 5 is interference-fitted inside the support bearing 4, so that the rotating shaft 5 is connected to the support bearing 4, and the rotating shaft 5 can rotate relative to the support bearing 4 and the support plate 1 through the support bearing 4. The drive gear 6 is welded to one end of the rotating shaft 5 or detachably fixed by bolts, so that the drive gear 6 and the rotating shaft 5 are connected together to form a whole, thereby enabling simultaneous rotation relative to the support bearing 4 and the support plate 1. The left toothed plate 3 meshes with the drive gear 6, so that the movement of the left toothed plate 3 drives the drive gear 6 to rotate. The drive gear 6 is meshed with the right toothed plate 10, so that the rotation of the drive gear 6 drives the rotation of the right toothed plate 10, thereby enabling the left toothed plate 3 and the right toothed plate 10 to move towards or away from each other under the extension and retraction of the hydraulic telescopic rod 2.

[0021] Reference Figure 1 , Figure 3 , Figure 4A limiting component is connected to the support plate 1 to limit the connection between the left toothed plate 3 and the right toothed plate 10, preventing them from disengaging from the drive gear 6 and thus affecting the rotation of the drive gear 6 and the relative movement of the left toothed plate 3 and the right toothed plate 10. The limiting component includes a left limiting plate 7, a left limiting block 8, a right limiting plate 11, and a right limiting block 12. The left limiting plate 7 and the right limiting plate 11 are detachably fixed to the support plate 1 by bolts, thus connecting them together and allowing the support plate 1 to support and limit the left and right limiting plates 7 and 11. The left limiting block 8 and the right limiting block 12 are welded to or detachably fixed to the left and right limiting plates 7 and 11 by bolts, forming a whole unit. The left toothed plate 3 and the right toothed plate 10 are provided with a left limiting groove 9 and a right limiting groove 13, respectively. The left limiting block 8 and the right limiting block 12 are slidably connected in the left limiting groove 9 and the right limiting groove 13, respectively. This allows the left limiting plate 7 to limit the left toothed plate 3 through the left limiting block 8 and the left limiting groove 9, and the right limiting plate 11 to limit the right toothed plate 10 through the right limiting block 12 and the right limiting groove 13. It also enables the left toothed plate 3 and the right toothed plate 10 to be movably connected to the support plate 1. In addition, it works with the drive gear 6 to prevent the left toothed plate 3 and the right toothed plate 10 from disengaging from the drive gear 6.

[0022] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4The left toothed plate 3 and the right toothed plate 10 are respectively connected to the left clamping plate 19 and the right clamping plate 23, so that the left toothed plate 3 and the right toothed plate 10 are connected to the left clamping plate 19 and the right clamping plate 23 respectively. Thus, by moving the left toothed plate 3 and the right toothed plate 10, the left clamping plate 19 and the right clamping plate 23 move simultaneously in a direction closer to or further away from each other, thereby achieving the clamping or releasing of the aluminum alloy by the left clamping plate 19 and the right clamping plate 23. The left toothed plate 3 and the right toothed plate 10 are respectively detachably fixedly connected to the left connecting rod 16 and the right connecting rod 20 by bolts, so that the left connecting rod 16 and the right connecting rod 20 are connected to the left toothed plate 3 and the right toothed plate 10 respectively to form a whole, thereby achieving simultaneous movement. The support plate 1 has a left sliding groove 14 and a right sliding groove 15. One end of the left connecting rod 16 and the right connecting rod 20 passes through the left sliding groove 14 and the right sliding groove 15, respectively, and is respectively welded or detachably fixed to the left slider 17 and the right slider 21 by bolts. This allows the ends of the left connecting rod 16 and the right connecting rod 20 away from the left toothed plate 3 and the right toothed plate 10 to pass through the support plate 1 and extend above the support plate 1, thereby limiting the left slider 17 and the right slider 21. In this way, the left slider 17 and the right slider 21 limit the left connecting rod 16 and the right connecting rod 20, respectively, to prevent the left connecting rod 16 and the right connecting rod 20 from being tilted relative to the support plate 1, thereby limiting the left toothed plate 3 and the right toothed plate 10. Left slider 17 and right slider 21 are respectively welded or detachably fixed with left clamping rod 18 and right clamping rod 22, so that left clamping rod 18 and right clamping rod 22 are connected to left slider 17 and right slider 21 to form a whole, enabling simultaneous movement. Left clamping plate 19 and right clamping plate 23 are respectively connected to left clamping rod 18 and right clamping rod 22, so that left clamping plate 19 and right clamping plate 23 are connected to left clamping rod 18 and right clamping rod 22, and then connected to left toothed plate 3 and right toothed plate 10, so that the movement of left toothed plate 3 and right toothed plate 10 drives left clamping plate 19 and right clamping plate 23 to move closer or further apart.

[0023] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4The left clamping plate 19 or the right clamping plate 23 includes a clamping plate 101, a connecting plate 102, and connecting springs 103. The clamping plate 101 has a moving groove. The connecting plate 102 is connected to the moving groove by several connecting springs 103, so that the connecting plate 102 is connected to the clamping plate 101 by several connecting springs 103, thereby enabling the connecting plate 102 to move relative to the contact plate in the moving groove. The connecting springs 103 provide elastic force between the connecting plate 102 and the clamping plate 101, reducing the buffering force when the clamping plate 101 contacts the aluminum alloy. The connecting plate 102 is welded to the left clamping rod 18 or the right clamping rod 22 or detachably fixed by bolts, so that the connecting plate 102 is connected to the left clamping rod 18 or the right clamping rod 22, thereby enabling the left clamping plate 19 and the right clamping plate 23 to be connected to the left clamping rod 18 and the right clamping rod 22 respectively, forming a whole.

[0024] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4An alarm assembly 24 is connected to either the left clamping plate 19 or the right clamping plate 23, enabling the alarm assembly to monitor whether the left clamping plate 19 and the right clamping plate 23 have applied excessive force to the aluminum alloy. The alarm assembly 24 includes an alarm housing 201, a trigger rod 203, a first trigger head 211, a second trigger head 213, a third trigger head 219, a fourth trigger head 223, an alarm light, and a buzzer. The trigger rod 203 is welded or detachably fixed to the clamping plate 101 by bolts, allowing the trigger rod 203 to move relative to the connecting plate 102. The connecting plate 102 has a through hole 104, and the trigger rod 203 is movably disposed within the through hole 104, allowing the trigger rod 203 to pass through the connecting plate 102 and thus enabling the trigger rod 203 to move relative to the connecting plate 102. The alarm housing 201 is detachably and fixedly connected to the end face of the connecting plate 102 away from the clamping plate 101 by bolts, so that the alarm housing 201 and the connecting plate 102 are connected together to form a whole. A movable hole 202 is provided inside the alarm housing 201, and one end of the trigger rod 203 extends into the movable hole 202, so that when the clamping plate 101 moves relative to the connecting plate 102, it drives the trigger rod 203 to move within the movable hole 202. A first mounting groove 204 and a second mounting groove 206 are provided on the outside of the trigger rod 203. A first conductive piece 205 and a second conductive piece 207 are respectively provided in the first mounting groove 204 and the second mounting groove 206, so that the first conductive piece 205 and the second conductive piece 207 are connected to the trigger rod 203, and the first mounting groove 204 and the second mounting groove 206 limit the first conductive piece 205 and the second conductive piece 207 to prevent them from detaching from the trigger rod 203. The outer surfaces of the first conductive sheet 205 and the second conductive sheet 207 are on the same plane as the outer surface of the trigger rod 203, preventing the first conductive sheet 205 and the second conductive sheet 207 from affecting the movement of the trigger rod 203 within the moving hole 202. The alarm housing 201 has a first mounting hole 208, a second mounting hole 212, a third mounting hole 216, and a fourth mounting hole 220 communicating with the moving hole 202. The first trigger head 211, the second trigger head 213, the third trigger head 219, and the fourth trigger head 223 are respectively disposed within the first mounting hole 208, the second mounting hole 212, the third mounting hole 216, and the fourth mounting hole 220, allowing them to move within these locations respectively.The first mounting hole 208, the second mounting hole 212, the third mounting hole 216, and the fourth mounting hole 220 are respectively threaded with a first connector 209, a second connector 215, a third connector 217, and a fourth connector 221, so that the first connector 209, the second connector 215, the third connector 217, and the fourth connector 221 respectively seal the external openings of the first mounting hole 208, the second mounting hole 212, the third mounting hole 216, and the fourth mounting hole 220. The first trigger head 211, the second trigger head 213, the third trigger head 219, and the fourth trigger head 223 are respectively connected to the first connector head 209, the second connector head 215, the third connector head 217, and the fourth connector head 221 via the first spring 210, the second spring 214, the third spring 218, and the fourth spring 222. This allows the first trigger head 211, the second trigger head 213, the third trigger head 219, and the fourth trigger head 223 to be connected to the first connector head 209, the second connector head 215, the third connector head 217, and the fourth connector head 221 within the first mounting hole 208, the second mounting hole 212, the third mounting hole 216, and the fourth mounting hole 220, respectively. This enables the first connector head 209, the second connector head 215, the third connector head 217, and the fourth connector head 221 to move relative to the first trigger head 211, the second trigger head 213, the third trigger head 219, and the fourth trigger head 223. The first connector 209 and the second connector 215 are electrically connected to the warning light, so that when the first trigger head 211 and the second trigger head 213 come into contact with the first conductive piece 205 or the second conductive piece 207, the circuit of the warning light is connected and energized, thereby enabling the warning light to emit a light warning, proving that the left clamping plate 19 and the right clamping plate 23 have clamped and fixed the aluminum alloy. The third connector 217 and the fourth connector 221 are electrically connected to the buzzer, so that when the third trigger head 219 and the fourth trigger head 223 come into contact with the first conductive piece 205 or the second conductive piece 207, the circuit of the buzzer is connected and energized, thereby enabling the buzzer to emit an audible warning, proving that the left clamping plate 19 and the right clamping plate 23 have clamped and fixed the aluminum alloy, and have tightened it to prevent further movement of the left toothed plate 3 and the right toothed plate 10 from continuing to clamp the aluminum alloy and causing damage. The warning light and buzzer are electrically connected to a power source, which provides power to the warning light and buzzer, enabling them to emit audible and visual alarms.The end of the trigger rod 203 inside the moving block is hemispherical. One end of the first trigger head 211, the second trigger head 213, the third trigger head 219, and the fourth trigger head 223 extends into the moving hole 202. The ends of the first trigger head 211, the second trigger head 213, the third trigger head 219, and the fourth trigger head 223 near the moving hole 202 are hemispherical, which allows the trigger rod 203 to press the first trigger head 211, the second trigger head 213, the third trigger head 219, and the fourth trigger head 223 back into the first mounting hole 208, the second mounting hole 212, the third mounting hole 216, and the fourth mounting hole 220, respectively. This allows the first trigger head 211, the second trigger head 213, the third trigger head 219, and the fourth trigger head 223 to abut against the trigger rod 203 under the elastic force of the first spring 210, the second spring 214, the third spring 218, and the fourth spring 222, respectively.

[0025] In use, the hydraulic telescopic rod 2 is first extended to move the left clamping plate 19 and the right clamping plate 23 away from each other, thus opening the left clamping plate 19 and the right clamping plate 23. Then, the aluminum alloy is placed on the support plate 1 between the left clamping plate 19 and the right clamping plate 23. Next, the hydraulic telescopic rod 2 is retracted, causing the left clamping plate 19 and the right clamping plate 23 to move closer together, thus clamping the aluminum alloy. When the clamping plate 101 on the left clamping plate 19 and the right clamping plate 23 contacts the aluminum alloy, the hydraulic telescopic rod 2 is retracted further, causing the clamping plate 101 to move towards the connecting plate 102, triggering the trip mechanism. The rod 203 moves into the moving hole 202. When the first trigger head 211 and the second trigger head 213 contact the second conductive plate 207 on the trigger rod 203, the circuit containing the first trigger head 211, the second trigger head 213 and the warning light is energized, so that the warning light is energized and produces a light warning. The conductive rod continues to move in the moving hole 202. When the third trigger head 219 and the fourth trigger head 223 contact the second conductive plate 207, the circuit containing the third trigger head 219, the fourth trigger head 223 and the buzzer is energized, so that the buzzer is energized and produces a sound warning.
