Description

Technical Field

[0001] This utility model relates to the field of metal fixture technology, and in particular to metal fixtures that are easy to assemble and disassemble. Background Technology

[0002] Metal fixtures are used in manufacturing and engineering to fix, support, or position workpieces during processing, assembly, and inspection. Fixtures can help ensure product consistency and accuracy, improve production efficiency, and reduce errors.

[0003] Common metal fixtures are usually designed with a fixed clamping force, and cannot adjust the clamping force according to the size, shape and material of different workpieces. Improper clamping force may lead to unexpected situations. When the clamping force is insufficient to firmly fix the workpiece, the workpiece may be displaced during processing, resulting in a decrease in processing accuracy, damage to the surface quality of the product, and even an increase in scrap rate. Excessive clamping force may exceed the tolerance range of the workpiece material, and the workpiece may be deformed, cracked or damaged in other ways.

[0004] Therefore, to address the problem that the aforementioned metal fixtures cannot adjust the clamping force according to the size, shape, and material of different workpieces, a metal fixture that is easy to assemble and disassemble can be designed. A strain gauge force sensing module provides real-time feedback of the clamping force to the controller, while a piezoelectric force sensing module continuously monitors the cutting force during processing and sends the signal to the controller. The controller then executes the corresponding commands based on calculations, thereby automatically adjusting the clamping force and cutting parameters to ensure that the clamping force is moderate and not excessive, preventing the workpiece from deforming or being damaged due to excessive pressure, and preventing over-clamping or under-clamping, thus solving the aforementioned problems. Utility Model Content

[0005] To overcome the problem that common metal jigs cannot adjust the clamping force according to the size, shape and material of different workpieces.

[0006] The technical solution of this utility model is as follows: a metal fixture that is easy to assemble and disassemble, including a base plate; it also includes a piezoelectric force sensing module, a high-speed data acquisition card, a digital conversion module, a controller, and a strain gauge force sensing module. Two electric push rods are fixedly connected to the upper surface of the base plate. The output ends of the two electric push rods are fixedly connected to a worktable. A placement groove is opened on the upper surface of the worktable. The piezoelectric force sensing module is installed on the bottom surface of the placement groove. The controller is installed on the upper surface of the base plate. Two moving components are installed on the upper surface of the base plate. Electric push rods are installed on the surface of the moving components. A mounting plate is fixedly connected to the output end of the electric push rods. A clamping plate is installed on the side of the mounting plate away from the electric push rods. A strain gauge force sensing module is installed in a groove on the side of the two clamping plates that are close to each other. A high-speed data acquisition card is installed on the upper surface of the base plate. A digital conversion module is installed on the upper surface of the base plate.

[0007] Preferably, the workpiece to be processed is placed in the placement slot of the worktable. The electric push rod one is activated to raise the worktable to an appropriate position. The position of the clamping plates is adjusted by the moving component so that they accurately surround the workpiece. The electric push rod two pushes the clamping plates closer to the workpiece. At the same time, the strain gauge force sensing module provides real-time feedback of the clamping force to the controller to ensure that the force value is moderate and not excessive. Once the clamping force reaches the preset standard, the processing equipment can be safely started. During this period, the piezoelectric force sensing module continuously monitors the cutting force to ensure that the processing process is always in the optimal state. The high-speed data acquisition card captures the signals from the piezoelectric force sensing module and the strain gauge force sensing module. The digital conversion module converts the signals captured by the high-speed data acquisition card into digital signals and sends them to the controller. The controller receives and processes the data from the sensors, executes the corresponding commands according to the calculation, and thus automatically adjusts the clamping force and cutting parameters to ensure that the clamping force is moderate and not excessive, to ensure that the workpiece is not deformed or damaged due to excessive pressure, and to ensure that the clamping force can always be maintained within the preset safety range to prevent over-clamping or under-clamping.

[0008] Preferably, the moving component includes a connecting block, a motor, a lead screw, a slide bar, a slider, a fixing block, and a connecting plate, with four connecting blocks welded to the upper surface of the base plate.

[0009] Preferably, a motor is mounted on the surface of each of the two connecting blocks on the left, and the output ends of the two motors are fixedly connected to one end of a lead screw, while the other end of the lead screw is rotatably connected to the inner surface of the connecting block on the right.

[0010] Preferably, the lead screw has a threaded connection to a slider, a fixing block is welded to the upper end of the slider, a connecting plate is fixedly connected to the upper end of the fixing block, and an electric push rod is installed on the surface of the connecting plate.

[0011] Preferably, a slide rod is fixedly connected between the two connecting blocks, and a slider is slidably connected to the surface of the slide rod.

[0012] Preferably, the bottom surface of the placement slot is fixedly connected to an anti-slip plate, the upper surface of the workbench is equipped with an audible alarm, and the upper surface of the workbench is equipped with an infrared temperature measurement module.

[0013] Preferably, the bottom of the base plate is fixedly connected to four support feet, and the bottom of the support feet is fitted with anti-slip pads.

[0014] The beneficial effects of this utility model are:

[0015] 1. Place the workpiece to be processed into the placement slot of the worktable. Activate the electric push rod one to raise the worktable to the appropriate position. Adjust the position of the clamping plates using the moving component to accurately surround the workpiece. The electric push rod two pushes the clamping plates closer to the workpiece. Simultaneously, the strain gauge force sensor module provides real-time feedback of the clamping force to the controller, ensuring that the force value is moderate and not excessive. Once the clamping force reaches the preset standard, the processing equipment can be safely started. During this period, the piezoelectric force sensor module continuously monitors the cutting force to ensure that the processing is always in the optimal state. The high-speed data acquisition card captures the signals from the piezoelectric force sensor module and the strain gauge force sensor module. The digital conversion module converts the signals captured by the high-speed data acquisition card into digital signals and sends them to the controller. The controller receives and processes the data from the sensors, executes corresponding commands based on calculations, and automatically adjusts the clamping force and cutting parameters to ensure that the clamping force is moderate and not excessive, ensuring that the workpiece will not be deformed or damaged due to excessive pressure, and ensuring that the clamping force can always be maintained within the preset safety range to prevent over-clamping or under-clamping.

Two electric push rods 2 are fixedly connected to the upper surface of the base plate 1, and the output ends of the two electric push rods 2 are fixedly connected to a worktable 3. A placement groove 4 is formed on the upper surface of the worktable 3, and the piezoelectric force sensing module 6 is installed on the bottom surface of the placement groove 4. A controller 11 is installed on the surface of the base plate 1. Two moving components are installed on the upper surface of the base plate 1. Electric push rods 20 are installed on the surface of the moving components. The output end of the electric push rods 20 is fixedly connected to a mounting plate 21. A clamping plate 22 is installed on the side of the mounting plate 21 away from the electric push rods 20. A strain gauge force sensing module 23 is installed in the groove on the side of the two clamping plates 22 that are close to each other. A high-speed data acquisition card 9 is installed on the upper surface of the base plate 1. A digital conversion module 10 is installed on the upper surface of the base plate 1.

[0023] Please see Figures 1-4 In this embodiment, the moving assembly includes connecting blocks 13, motors 14, lead screws 15, slide bars 16, sliders 17, fixing blocks 18, and connecting plates 19. Four connecting blocks 13 are welded to the upper surface of the base plate 1. The moving assembly is used to drive the clamping mechanism to move left and right, allowing adjustment of the clamping mechanism's position and facilitating clamping of parts. A motor 14 is mounted on the surface of each of the two left connecting blocks 13. The output ends of the two motors 14 are fixedly connected to one end of a lead screw 15, and the other end of the lead screw 15 is rotatably connected to the inner surface of the right connecting block 13. The rotation of the machine 14 drives the lead screw 15 to rotate synchronously. Since there is a threaded connection between the lead screw 15 and the slider 17, the slider 17 will move along its axis under the rotation of the lead screw 15. The slider 17 is threadedly connected to the surface of the lead screw 15. A fixing block 18 is welded to the upper end of the slider 17. A connecting plate 19 is fixedly connected to the upper end of the fixing block 18. An electric push rod 20 is installed on the surface of the connecting plate 19. The rotation of the lead screw 15 can drive the slider 17 to move along the direction of the lead screw 15. The mechanism connected to the slider 17 will also move. Activating the electric push rod 20 can drive the clamping plate 22 to move.

[0024] Please see Figures 1-4In this embodiment, a slide rod 16 is fixedly connected between the two connecting blocks 13, and a slider 17 is slidably connected to the surface of the slide rod 16. The slide rod 16 can limit the slider 17 and support it, improving the movement stability of the slider 17. An anti-slip plate 5 is fixedly connected to the bottom surface of the placement groove 4. An audible alarm 8 is installed on the upper surface of the worktable 3, and an infrared temperature measurement module 7 is installed on the upper surface of the worktable 3. The anti-slip plate 5 provides additional friction to prevent the workpiece from sliding or shifting on its surface, ensuring the stability of the workpiece before and after clamping and improving processing accuracy. The infrared temperature measurement module 7 monitors the temperature change of the processing area in real time. To prevent workpiece deformation or tool wear due to overheating, the temperature data is fed back to the controller 11 for necessary adjustments or alarms. An alarm sound is issued when abnormal conditions are detected, such as clamping force exceeding the safe range, excessive temperature, or other malfunctions. Four support feet 12 are fixedly connected to the lower end of the base plate 1. The lower end of the support feet 12 is fitted with anti-slip pads. The support feet 12 provide stable support to ensure the stability and levelness of the entire device during processing. The anti-slip pads are made of rubber with a high coefficient of friction, which can enhance the friction between the fixture and the ground, prevent slippage or tipping, and absorb slight vibrations to reduce the impact of external factors on processing accuracy.

[0025] During operation, the workpiece to be processed is placed in the placement slot 4 of the worktable 3. The electric push rod 21 raises the worktable 3 to an appropriate position. The position of the clamping plates 22 is adjusted by the moving component so that they accurately surround the workpiece. The electric push rod 22 pushes the clamping plates 22 closer to the workpiece. At the same time, the strain gauge force sensing module 23 feeds back the clamping force to the controller 11 in real time to ensure that the force value is moderate and not excessive. Once the clamping force reaches the preset standard, the processing equipment can be safely started. During this period, the piezoelectric force sensing module 6 continuously monitors the cutting force to ensure that the processing is always in the best state. The high-speed data acquisition card 9 captures the data from the piezoelectric force sensing module 6 and the strain gauge force sensing module 11. The signal from the sensing module 23 is converted into a digital signal by the high-speed data acquisition card 9 by the digital conversion module 10 and sent to the controller 11. The controller 11 receives and processes the data from the sensor, executes corresponding commands according to calculations, and automatically adjusts the clamping force and cutting parameters to ensure that the clamping force is moderate and not excessive, ensuring that the workpiece will not be deformed or damaged due to excessive pressure, and ensuring that the clamping force can always be maintained within the preset safety range to prevent over-clamping or under-clamping. The moving component is used to drive the clamping mechanism to move left and right, and can adjust the position of the clamping mechanism to facilitate the clamping operation of the workpiece. The motor... The rotation of screw 14 drives screw 15 to rotate synchronously. Since there is a threaded connection between screw 15 and slider 17, slider 17 moves along its axis under the rotation of screw 15. The rotation of screw 15 can drive slider 17 to move along the direction of screw 15, and the mechanism connected to slider 17 will also move. Activating electric push rod 20 can drive clamping plate 22 to move. The sliding rod 16 limits slider 17 and provides support, improving the stability of slider 17's movement. Anti-slip plate 5 provides additional friction to prevent workpiece from sliding or displacing on its surface, ensuring the workpiece remains stable before and after clamping. To improve stability and machining accuracy, the infrared temperature measurement module 7 monitors the temperature changes in the machining area in real time, preventing workpiece deformation or tool wear caused by overheating. It feeds back the temperature data to the controller 11 for necessary adjustments or alarms. An alarm is sounded when abnormal conditions are detected, such as clamping force exceeding the safe range, excessive temperature, or other malfunctions. The support feet 12 provide stable support, ensuring the stability and levelness of the entire device during machining. The anti-slip pads are made of rubber with a high coefficient of friction, which can enhance the friction between the fixture and the ground, preventing slippage or tipping. At the same time, it can absorb slight vibrations and reduce the impact of external factors on machining accuracy.

[0026] Following the above steps, the workpiece to be processed is placed in the placement slot 4 of the worktable 3. The electric push rod 21 raises the worktable 3 to an appropriate position. The position of the clamping plates 22 is adjusted by the moving assembly to accurately surround the workpiece. The electric push rod 22 pushes the clamping plates 22 closer to the workpiece. Simultaneously, the strain gauge force sensing module 23 provides real-time feedback of the clamping force to the controller 11, ensuring the force value is moderate and not excessive. Once the clamping force reaches the preset standard, the processing equipment can be safely started. During this period, the piezoelectric force sensing module 6 continuously monitors the cutting force to ensure the processing is always in optimal condition. The high-speed data acquisition card 9 captures the data from the piezoelectric force sensing module 6. The signal from the strain gauge force sensing module 23 is converted into a digital signal by the high-speed data acquisition card 9 by the digital conversion module 10 and sent to the controller 11. The controller 11 receives and processes the data from the sensor, executes the corresponding command according to the calculation, and automatically adjusts the clamping force and cutting parameters to ensure that the clamping force is moderate and not excessive, and to ensure that the workpiece will not be deformed or damaged due to excessive pressure. It also ensures that the clamping force can always be maintained within the preset safety range, and prevents over-clamping or under-clamping. This solves the problem that common metal jigs cannot adjust the corresponding clamping force according to the size, shape and material of different workpieces.
