Description

Technical Field

[0001] This utility model relates to the field of clamps, specifically an alloy plate cutting clamp. Background Technology

[0002] Alloy plate blanking fixtures are key tooling equipment used in the machining field to fix and position alloy plates to ensure blanking accuracy and processing stability. They are widely used in industries such as aerospace, automobile manufacturing, and precision instruments.

[0003] Current clamps achieve material unloading through precise and stable gripping. However, in actual use, prolonged high-load operation of the clamps can lead to a decline in gripping performance. During loading, haphazard placement of alloy plates can cause them to fall during transportation, creating safety hazards. Therefore, the inventors urgently need to design a structure that can neatly arrange alloy plates to increase work efficiency. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide an alloy plate unloading fixture to solve the technical problems of alloy plates being skewed and not neatly arranged.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an alloy plate unloading fixture, comprising an unloading machine body, wherein first motors are symmetrically mounted on both sides of the unloading machine body, and commutators are fixedly connected to the output ends of the first motors. A lever is rigidly connected to the commutator, and the lever is driven to rotate by the first motor. Through contact between the lever and the alloy plate, the alloy plate is positioned accurately for unloading. A photoelectric sensor is provided on one side of the unloading machine body, employing advanced sensing technology. The photoelectric sensor is used to monitor the state of the alloy plate in real time.

[0006] By adopting the above technical solution, the first motor drives the commutator and the paddle to rotate in coordination on both sides of the main body of the feeding machine. The physical contact between the paddle and the alloy plate realizes dynamic position correction, which effectively solves the positioning deviation problem caused by the inertia or transmission offset of the plate and ensures that the alloy plate accurately reaches the preset feeding position.

[0007] Furthermore, the bottom of the photoelectric sensor is provided with a protrusion, which is embedded in a groove and moves horizontally along the groove.

[0008] By adopting the above technical solution, the bottom protrusion of the photoelectric sensor is embedded in the groove, allowing the sensor to move freely horizontally and flexibly adapt to the monitoring area requirements of alloy plates of different sizes, thus avoiding monitoring blind spots caused by fixed equipment layout.

[0009] Furthermore, the main body of the feeding machine is equipped with a conveyor belt, which is supported by multiple parallel rollers and driven by the rollers to achieve continuous operation, with a smooth and flat surface.

[0010] By adopting the above technical solution, the conveyor belt is supported and driven by multiple parallel rollers to form a continuous and stable conveying plane, ensuring that the alloy plate is subjected to uniform force during transmission and avoiding deformation or surface scratches caused by single-point pressure.

[0011] Furthermore, a second motor is installed on the main body of the feeding machine, and the second motor is connected to the second rotating shaft for transmission, and the second motor drives the shaft to rotate.

[0012] By adopting the above technical solution, the second motor installed on the main body of the feeding machine is directly connected to the second rotating shaft, and the rotating shaft is driven by a single power source, which simplifies the transmission chain structure, reduces the mechanical failure rate, and improves the energy transmission efficiency.

[0013] Furthermore, several sets of clamps are installed on the second rotating shaft, and a lifting rod is provided at the front end of the clamp. The lifting rod reciprocates in the vertical direction, and a suction cup is vertically installed below the lifting rod.

[0014] By adopting the above technical solution, several sets of clamps are set on the second rotating shaft, and its lifting rod reciprocates in the vertical direction. Combined with the vertical lifting path of the suction cup below, it ensures that the clamping action is strictly perpendicular to the plane of the plate, avoiding oblique force that could cause displacement of the alloy plate or surface damage.

[0015] Furthermore, the suction cup is disc-shaped with a flat surface and a downwardly recessed adsorption area, and moves vertically under the drive of the lifting rod to clamp or release materials.

[0016] By adopting the above technical solution, the flat surface of the disc-shaped suction cup increases the contact area. Combined with the negative pressure cavity formed by the downward concavity of the adsorption area, a uniform vacuum adsorption force is quickly formed when in contact with the board, avoiding clamping failure caused by local air leakage.

[0017] Furthermore, the paddle is available in two, but not limited to, sizes to accommodate different materials and usage scenarios.

[0018] By adopting the above technical solution, the paddle provides at least two interchangeable sizes, enabling the fixture to quickly adapt to the correction needs of alloy plates of different lengths or widths. The large paddle is suitable for wide plates to enhance the correction torque, while the small paddle is suitable for narrow or precision parts to avoid excessive interference.

[0019] In summary, the present invention has the following main advantages:

[0020] 1. This utility model, through the design of the paddle, uses a symmetrically arranged first motor to drive the paddle directly to contact the alloy plate for physical correction via a commutator, ensuring the immediacy and accuracy of position adjustment and avoiding the efficiency bottleneck of traditional manual positioning. At the same time, the photoelectric sensor, combined with the lateral movement of the protrusion and groove design, enables dynamic adjustment of the monitoring position, adapting to various sizes of plates. The replaceable paddle size further expands the equipment compatibility, reduces the cost of changing models, and forms a high-precision and highly flexible positioning system.

[0021] 2. This utility model uses a suction cup design, with a second motor driving a second rotating shaft to move the lifting rod vertically, ensuring that the suction cup always acts vertically on the surface of the board. Its disc-shaped concave structure enhances adsorption stability, avoids material deformation caused by oblique force, and ensures zero damage during the clamping process. The roller support of the conveyor belt and the smooth surface provide smooth and damage-free transportation, eliminating the risk of scratches or displacement of the board. The entire process is optimized through mechanical collaboration, taking into account both efficient material feeding and protection of material integrity. Attached Figure Description

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] In this embodiment:

[0029] An alloy plate blanking fixture, such as Figure 1-4As shown, the system includes a feeding machine body 12, with first motors 3 symmetrically mounted on both sides of the feeding machine body 12. A commutator 2 is fixedly connected to the output end of the first motor 3, and a lever 1 is rigidly connected to the commutator 2. The lever 1 is driven to rotate by the first motor 3. Through contact between the lever 1 and the alloy plate, the plate is positioned accurately for feeding. A photoelectric sensor 4 is installed on one side of the feeding machine body 12. The photoelectric sensor 4 uses advanced sensing technology to monitor the state of the alloy plate in real time. The first motors 3 symmetrically mounted on both sides of the feeding machine body 12 drive the commutator 2 and the lever 1 to rotate in tandem. Dynamic position correction is achieved through the physical contact between the lever 1 and the alloy plate, effectively solving the positioning deviation problem caused by inertia or transmission offset of the plate. This ensures that the alloy plate accurately reaches the preset feeding position. Combined with the photoelectric sensor 4 using advanced sensing technology to monitor the plate state in real time, a closed-loop feedback mechanism is formed. Sensor data can trigger the first motor 3 to act instantly, significantly reducing the need for manual intervention, improving the system's automation level and response speed, and significantly improving feeding accuracy and efficiency.

[0030] See Figure 1 , Figure 2 , Figure 4 The photoelectric sensor 4 has a protrusion 6 at its bottom, which is embedded in the groove 5. The protrusion 6 moves horizontally along the groove 5, allowing the sensor to move freely horizontally. This allows it to flexibly adapt to the monitoring area requirements of alloy plates of different sizes, avoiding blind spots caused by fixed equipment layout. The sliding structure gives the sensor position dynamic adjustability. When the plate specifications change or the process requirements are adjusted, there is no need to disassemble the photoelectric sensor 4 as a whole. The monitoring point can be quickly repositioned by lateral displacement, which greatly improves the equipment's versatility and maintenance convenience, reduces the changeover time cost in multi-variety, small-batch production, and enhances the flexible adaptability of the production line.

[0031] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The main body 12 of the feeding machine is equipped with a conveyor belt 7, which is supported by multiple parallel rollers. The conveyor belt 7 is driven by the rollers to achieve continuous operation. The surface is flat and smooth. The conveyor belt 7 is supported and driven by multiple parallel rollers to form a continuous and stable conveying plane, which ensures that the alloy plate is subjected to uniform force during the transmission process and avoids deformation or surface scratches caused by single-point pressure. The flat and smooth surface characteristics significantly reduce the frictional resistance between the plate and the conveyor belt 7, which not only reduces the risk of damage to the plate surface, but also ensures that the plate moves forward at a uniform speed without shaking, thereby improving product quality.

[0032] See Figure 1 , Figure 2 , Figure 3 , Figure 4A second motor 10 is installed on the main body 12 of the feeding machine. The second motor 10 is connected to the second rotating shaft 11 through a transmission. The second motor 10 drives the shaft to rotate. By directly driving the second rotating shaft 11 through the second motor 10 installed on the main body 12 of the feeding machine, the shaft is driven to rotate by a single power source, which simplifies the transmission chain structure, reduces the mechanical failure rate and improves the energy transfer efficiency. The high synchronization control capability of the rotating shaft ensures that the speed and direction of the second rotating shaft 11 can be accurately matched with the feeding cycle requirements, avoids the timing errors that may be caused by the coordination of multiple motors, and ensures the timing accuracy of the entire clamping and releasing process.

[0033] See Figure 1 , Figure 2 , Figure 3 , Figure 4 Several sets of clamps are installed on the second rotating shaft 11. A lifting rod 9 is set at the front end of the clamp. The lifting rod 9 reciprocates in the vertical direction. A suction cup 8 is vertically installed below the lifting rod 9. The lifting rod 9, combined with the vertical lifting path of the suction cup 8 below, ensures that the clamping action is strictly perpendicular to the plane of the plate, avoiding oblique force that could cause displacement or surface damage to the alloy plate. The structure of the suction cup 8 being vertically installed at the end of the lifting rod 9 allows the suction cup 8 to adjust the contact pressure through the lifting rod 9 when it contacts the plate, adapting to minor unevenness on the plate surface, preventing overload impact, and improving product quality.

[0034] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The suction cup 8 is disc-shaped with a flat surface and a downward-concave adsorption area. Driven by the lifting rod 9, it moves vertically to clamp or release materials. The flat surface of the disc-shaped suction cup 8 increases the contact area. Combined with the negative pressure cavity formed by the downward-concave adsorption area, it quickly forms a uniform vacuum adsorption force when in contact with the board, avoiding clamping failure caused by local air leakage. The concave structure enhances airtightness, reduces the risk of board shaking or slippage, and ensures the flexibility and controllability of the unloading action.

[0035] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The lever 1 comes in two, but not limited to, sizes to adapt to different material sizes and application scenarios. The lever 1 provides at least two interchangeable sizes, allowing the fixture to quickly adapt to the correction needs of alloy plates of different lengths or widths. The large lever is suitable for wide plates to enhance the correction torque, while the small lever is suitable for narrow or precision parts to avoid excessive interference, significantly reducing equipment upgrade costs and production line downtime, and enhancing the economic efficiency and sustainability of the fixture throughout its entire life cycle.

[0036] The implementation principle of this embodiment is as follows: After the main body 12 of the unloading machine is started, the second motor 10 drives the second rotating shaft 11 to rotate, which drives the clamping device installed on it to a suitable position. The alloy plate is placed on the conveyor belt 7, which is supported by parallel rollers and runs continuously and smoothly. During the operation, the photoelectric sensor 4 monitors the position status of the alloy plate in real time. If a deviation is detected, the first motor 3 drives the commutator 2 and the lever 1 to rotate. The lever 1 corrects the alloy plate to the accurate placement position required for unloading by contacting it. At the same time, the photoelectric sensor 4 can move horizontally in the groove 5 through the protrusion 6 at its bottom to adapt to the monitoring requirements. After the correction is completed, the lifting rod 9 of the clamp moves back and forth in the vertical direction. The suction cup 8 below the lifting rod 9 moves vertically accordingly. The suction cup 8 with a flat surface and a downward-concave adsorption area clamps the alloy plate. The second motor 10 drives the second rotating shaft 11 to rotate 180 degrees to complete the unloading operation.
