[0004] Shearing equipment for automotive metal parts manufacturing is specialized equipment used to shear metal parts to obtain components of the desired shape and size. Its core function is to achieve precise cutting of sheet metal through mechanical, hydraulic, and CNC technologies.

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0027] like Figures 1 to 10 As shown, an automobile metal parts manufacturing shearing equipment described in an embodiment of the present invention includes a workbench, four fixed support assemblies are fixedly installed at the middle position of the top of the workbench, and the four fixed support assemblies are used to perform preliminary positioning and support for the metal parts. Four auxiliary support assemblies are provided on the top of the workbench, and the auxiliary support assemblies are provided on the outside of the fixed support assemblies. The auxiliary support assemblies are used to cooperate with the fixed support assemblies to support the metal parts. Four vertical plates are fixedly installed on the top of the workbench, and one side of the four vertical plates is provided with a clamping assembly. The clamping assembly is placed on one side of the auxiliary support assembly, and the clamping assembly is used to clamp the outside of the metal parts. The clamping assembly includes a clamping box 5, and a plurality of pushing shafts 506 are provided inside the clamping box 5. An elastic clamping plate 501 is fixedly installed on one end of the plurality of pushing shafts 506. One side of the elastic clamping plate 501 can be fitted with the outer wall of the metal part. A pushing assembly is provided inside 5, and a laser shear is provided on the top of the workbench; Because the existing clamping and supporting device may not be able to fully fit the outside of the metal part when clamping and supporting the outside of the metal part with a relatively irregular appearance, it may be loose or shaken during the shearing process, which may easily lead to a decrease in cutting quality and is not conducive to the shearing of the metal part; When it is necessary to shear the metal part, the metal part is placed directly above the fixed support assembly by using a pick-and-place device, so that the fixed support assembly can initially support the metal part. When the fixed support assembly has initially supported the metal part, the auxiliary support assembly is driven to perform auxiliary support on all sides of the metal part, so that it cooperates with the fixed support assembly to support the metal part. Subsequently, the pushing assembly in the clamping assembly is driven to push multiple pushing shafts 506 to drive the elastic clamping plate 501 to move. When the elastic clamping plate 501 completely contacts the outer wall of the metal part, the clamping operation is completed. Multiple clamp components clamp and tighten the metal parts on all sides. When all three have completed the corresponding operations on the metal parts, the support and positioning operations of the metal parts are completed. Then, the laser shear 201 is driven to move and shear the metal parts, thereby realizing the automatic shearing operation of the metal parts. During the cutting process, the three positioning methods are controlled by the system to work together. The clamping force and the supporting force are automatically adjusted according to the cutting force to ensure that the metal parts can remain stable under any circumstances, prevent the metal parts from shaking during shearing, and affect the cutting operation, which is more conducive to the cutting operation of the metal parts.

[0028] like Figures 1 to 2 As shown, a driving and cutting mechanism 2 is mounted on the top of the workbench 1, and one end of the laser shear 201 is disposed inside the driving and cutting mechanism 2; When the laser shear 201 is driven to move and cut, the shape to be cut is input into the cutting mechanism 2 through the system, and the cutting mechanism 2 will drive the laser shear 201 to move and cut the metal part according to the information input by the system, thereby controlling and driving the laser shear 201 to cut metal parts with different shapes. It should be noted here that the laser shear 201 is a laser cutting machine, which is a device that uses a high-power density laser beam to irradiate the workpiece to quickly melt, vaporize, ablate or reach the ignition point of the material, and at the same time uses a high-speed airflow coaxial with the light beam to blow away the molten material, thereby achieving the cutting of the workpiece. The cutting mechanism 2 is a component that drives the laser cutting head to move and realize the cutting function, and can be composed of a servo motor, a screw rod and a slider, etc. Both are existing technologies, so they are only described in this scheme, and the specific structure is not displayed.

[0029] like Figures 3 to 7 As shown, the fixed support assembly includes a hollow shaft 7, which is fixedly mounted on the top of the workbench 1. The inner wall of the hollow shaft 7 is slidably connected to a support shaft 702. The top of the support shaft 702 is fixedly mounted with a wheel axle 703. The top of the wheel axle 703 can fit with the outer wall of the metal part. A support spring 701 is provided between the bottom of the support shaft 702 and the top of the workbench 1. When the metal parts need to be placed, by placing the metal parts on top of the four axles 703, the metal parts will slide in the hollow shaft 7 by pressing the support shaft 702 under gravity, squeezing the support spring 701. When the metal parts are completely placed on the top of the four axles 703, the four axles 703 will initially support the metal parts through the elastic force of the support spring 701, thereby achieving the effect of initially placing and supporting the metal parts.

[0030] like Figures 1 to 3 As shown, camera identifiers 4 are fixedly installed on the top of the four vertical plates 3 and the four corners of the top of the workbench 1; When the metal part is placed on the top of the four axles 703, the top and bottom of the metal part are scanned and detected by multiple camera identifiers 4 to obtain the contour information of the metal part. The system will calculate the optimal position and height of each auxiliary support component and clamp component based on the clipping path and the shape of the metal part, and control the auxiliary support component and clamp component to automatically adjust into place, thereby scanning and obtaining the contour information of the metal part and controlling the auxiliary support component and clamp component to automatically adjust.

[0031] like Figures 3 to 9 As shown, the auxiliary support assembly includes a motor 601, the output end of the motor 601 is fixedly mounted with a shaft 6, the top of the shaft 6 is fixedly mounted with a ring rail 14, the inner portion of the ring rail 14 is slidably provided with an indexing actuator 1401, one end of the indexing actuator 1401 is fixedly mounted with a rectangular box 8, and the outer wall of the rectangular box 8 is slidably connected to the outer wall of the ring rail 14; When the camera identifier 4 finishes scanning and detecting, the system controls the four auxiliary support components to be moved to appropriate support positions respectively, and then controls the indexing actuator 1401 to drive the moment box 8 to rotate on the ring rail 14, so that the moment box 8 rotates to an appropriate support point. When the rotation adjustment of the moment box 8 is completed, the control motor 601 drives the shaft 6 to move upward, and the motor 601 drives the moment box 8 to move toward the bottom of the metal part through the ring rail 14. When the tops of the four moment boxes 8 each touch the bottom of the metal part, the four moment boxes 8 will press the bottom four of the metal part. The metal parts are supported around the periphery, thereby cooperating with the fixed support assembly to support the metal parts, playing the role of bottom support for the metal parts. The four sets of auxiliary support assemblies can each perform independent support adjustment, and cooperate with the transfer actuator 1401 to drive the moment box 8 to rotate and adjust, so that when the device supports the metal parts, it can adapt to the support requirements of metal parts of different shapes and metal parts during shearing. It should be noted that the transfer actuator 1401 is a mechanical device for realizing the rotation, transposition and other actions of objects, which is generally composed of a driving source, a transmission mechanism and an executive component. The driving source provides power, and common driving sources include motors, hydraulic pumps or pneumatic pumps. The power is transmitted to the executive component through the transmission mechanism, so that the executive component rotates or moves in a predetermined manner, thereby realizing the transfer of the object. It is a prior art solution, so it is only described and stated in this solution, and is not displayed.

[0032] like Figures 2 to 3 As shown, a guide rail 101 is installed inside the workbench 1, and an electric slider 102 is slidably connected to the inside of the guide rail 101. The top of the electric slider 102 is fixedly connected to the bottom of the motor 601, and the outer wall of the shaft 6 is slidably connected to the inner wall of the workbench 1; When the camera identifier 4 completes its scanning and detection operation, the system captures the support position, and then the system controls the electric slider 102 to drive the shaft 6 to move relative to the guide rail 101, so that the electric slider 102 drives multiple torque boxes 8 to adjust their positions at the bottom of the metal part, thereby driving the torque boxes 8 to adjust the support position.

[0033] like Figures 3 to 6As shown, the pushing assembly includes a pushing block 505, and there are two clamping boxes 5. The setting structures in the two clamping boxes 5 are the same. The pushing block 505 is slidably connected to the inside of the clamping box 5. The top of the pushing block 505 is fixedly installed with a magnetic block 502, and the outer wall of the magnetic block 502 can be slidably connected to the inner wall of the clamping box 5. The inner wall of the clamping box 5 is fixedly installed with an electromagnet 503, and the setting of the electromagnet 503 corresponds to the setting position of the magnetic block 502. The outer walls of the multiple pushing shafts 506 are fixedly installed with moment blocks 507, and the outer walls of the multiple pushing shafts 506 can be slidably connected to the inner walls of the clamping box 5 and the pushing block 505. A return spring 504 is provided between one side of the pushing block 505 and one side of the multiple moment blocks 507, and the multiple return springs 504 are respectively placed on the outside of the multiple pushing shafts 506; When the square box 8 finishes supporting the metal part, the electromagnet 503 is driven to pull the magnetic block 502, and the magnetic block 502 will drive the push block 505 to move in the clamping box 5. When the push block 505 moves, the reset spring 504 is elastically retained, and the push block 505 will drive the elastic clamping plate 501 to move through multiple pushing shafts 506. Due to the uneven outer wall of the metal part, when the elastic clamping plate 501 moves to fit the outer wall of the metal part, one end of the elastic clamping plate 501 that fits the outer wall of the metal part will be restricted, and the push block 505 will continue to push. , the elastic clamping plate 501 will slide toward the inside of the clamping box 5 through the moment block 507 to squeeze the return spring 504. When the push block 505 pushes multiple moment blocks 507 to drive the elastic clamping plate 501 to completely fit the outer wall of the metal part, the outer wall clamping operation of the metal part is completed. The metal part is clamped on all sides by multiple clamping components cooperating with each other, thereby realizing the clamping operation of the outer wall of the metal part, playing the role of clamping metal parts of different shapes. By working together with the auxiliary support component and the fixed support component, the trinity effect of supporting and fixing metal parts of various shapes can be achieved.

[0034] like Figures 4 to 6 As shown, a limited sliding rod 12 is provided between the two clamping boxes 5, and a connecting rod 602 is fixedly installed at the bottom of the limited sliding rod 12, and one end of the connecting rod 602 is fixedly connected to the outer wall of the shaft 6; The clamping box 5 is connected to the shaft 6 by the connecting rod 602. When the shaft 6 moves upward to drive the moment box 8 to support the bottom of the metal part, the shaft 6 can also drive the clamping box 5 to move upward, so that the clamping assembly can be adjusted in position according to the upward movement distance of the auxiliary support assembly. No matter what height the auxiliary support assembly rises to, the clamping assembly is always placed on one side of the auxiliary support assembly to clamp the outer wall of the metal part, thereby playing the role of synchronously adjusting the position.

[0035] like Figures 4 and 5As shown, one side of the two clamping boxes 5 is fixedly installed with a shift block 13, the outer walls of the two shift blocks 13 are slidably connected to the inner wall of the sliding limit rod 12, and a return block spring 1201 is provided between one side of the two shift blocks 13 and the inner wall of the sliding limit rod 12, the outer walls of the two shift blocks 13 are fixedly installed with a limiting slot rod 1301, the inner wall of the vertical plate 3 is slidably connected with a positioning block 901, one end of the positioning block 901 is fixedly installed with an axis block 9, the outer wall of the axis block 9 is symmetrically hinged with a hinge rod 10, one end of the two hinge rods 10 are respectively slidably connected to the inner walls of the two limiting slot rods 1301, and a push rod 11 is fixedly installed on one side of the sliding limit rod 12, and one end of the push rod 11 can slide in contact with the inner walls of the two hinge rods 10; Since the width and length of each metal part are different, when the laser shear 201 drives the shaft rod 6 to move, the shaft rod 6 will drive the clamping box 5 to move together through the connecting rod 602 and the sliding limit rod 12. When the clamping box 5 moves outward, the clamping box 5 will drive the push rod 11 to move through the sliding limit rod 12. The push rod 11 will push the two hinge rods 10 to rotate and open on the shaft block 9. The two hinge rods 10 will hinge and rotate to push the two limit slot rods 1301 to move outward, so that the limit slot rod 1301 passes through the shift block 13 Pull the return block spring 1201 to move outward in the sliding rod 12, and the two clamping boxes 5 will move and adjust to both sides in the sliding rod 12 through the shift block 13. Anyway, when the clamping box 5 moves inward, the two clamping boxes 5 will move inward relative to each other through the shift block 13 through the elastic pulling of the return block spring 1201, so that the distance between the two clamping boxes 5 can be adjusted according to the supporting point of the shaft rod 6, so that the clamping point between the two clamping components on one side can be adjusted according to the width or length of the metal part, so that it can better clamp the metal part.

[0036] like Figures 9 and 10 As shown, a sensor 802 is fixedly mounted on the inner wall of the rectangular box 8, and an auxiliary support block 801 is slidably connected to the top of the inner wall of the rectangular box 8. A plurality of pressure springs 803 are provided between the bottom of the auxiliary support block 801 and the inner wall of the rectangular box 8. The bottom of the auxiliary support block 801 can fit in contact with the top of the sensor 802, and a rubber cushion is provided on the top of the auxiliary support block 801. When the rectangular box 8 moves upward to support the bottom of the metal part, the rectangular box 8 will drive the auxiliary support block 801 to move. When the auxiliary support block 801 contacts the outer wall of the metal part, the auxiliary support block 801 will be pressed in the rectangular box 8 to squeeze the pressure spring 803 to move downward. When the bottom of the auxiliary support block 801 contacts the sensor 802, the rectangular box 8 stops moving upward. At this time, the auxiliary support operation of the metal part is completed. Subsequently, the metal part is clamped by the clamping assembly, completing the three-in-one support and fixing operation of the metal part. When the laser shear 201 moves to shear the metal part, During the cutting operation, if the auxiliary support block 801 loses contact with the sensor 802, it means that the metal part has been displaced or deformed. The sensor 802 will then control the auxiliary support assembly and the clamp assembly through the system to make relative adjustments, adjust the support position and clamping force, and dynamically support the plate to ensure the stability of the plate during the cutting process, and play a role in detecting whether the metal part is displaced or deformed during the shearing process. It should be noted here that the rubber cushion should be made of flexible material, which can provide sufficient support force while avoiding scratches on the surface of the metal plate.

[0037] Working principle: When it is necessary to shear a metal part, the metal part is placed directly above the fixed support assembly by using a pick-and-place device, so that the fixed support assembly can initially support the metal part. When the fixed support assembly has initially supported the metal part, the auxiliary support assembly is driven to provide auxiliary support around the metal part, so that it can cooperate with the fixed support assembly to support the metal part. Then, the pushing assembly in the clamping assembly is driven to push multiple pushing shafts 506 to drive the elastic clamping plate 501 to move. When the elastic clamping plate 501 completely contacts the outer wall of the metal part, the clamping operation is completed. The metal part is clamped and fastened on all sides by multiple clamping components. When all three components have completed their corresponding operations on the metal part, the metal part is supported and positioned. Subsequently, the metal part is moved and sheared by driving the laser shear 201, thereby realizing the automatic shearing operation of the metal part. During the shearing process, the three positioning methods are controlled by the system to work together. The clamping force and the supporting force are automatically adjusted according to the shearing force, ensuring that the metal part can remain stable under any circumstances, preventing the metal part from shaking during shearing, which affects the cutting operation and is more conducive to the shearing operation of the metal part. When the laser shear 201 is driven to perform mobile shearing, the shape to be sheared is input into the driving and cutting mechanism 2 through the system, and the driving and cutting mechanism 2 drives the laser shear 201 to perform mobile shearing operations on the metal part according to the information input by the system, thereby controlling and driving the laser shear 201 to shear metal parts of different shapes; When the metal part needs to be placed, the metal part is placed on top of the four wheel axles 703. The metal part will slide inside the hollow shaft 7 by pressing the support shaft 702 under gravity, squeezing the support spring 701. When the metal part is completely placed on top of the four wheel axles 703, the four wheel axles 703 will initially support the metal part through the elastic force of the support spring 701, thereby achieving the function of initially placing and supporting the metal part. When a metal part is placed on top of the four axles 703, the top and bottom of the metal part are scanned and detected by multiple camera identifiers 4 to obtain the contour information of the metal part. The system will then calculate the optimal position and height of each auxiliary support component and clamp component based on the cutting path and the shape of the metal part, and control the auxiliary support components and clamp components to automatically adjust them into place, thereby scanning and obtaining the contour information of the metal part and controlling the auxiliary support components and clamp components to automatically adjust them. When the scanning and detection operation of the camera identifier 4 is completed, the system controls the four auxiliary support components to be moved to the appropriate support positions respectively, and then controls the indexing actuator 1401 to drive the torque box 8 to rotate on the ring rail 14, so that the torque box 8 is rotated to the appropriate support point. When the rotation adjustment of the torque box 8 is completed, the control motor 601 drives the shaft 6 to move upward, and the motor 601 will drive the torque box 8 to move to the bottom of the metal part through the ring rail 14. When the tops of the four torque boxes 8 each contact the bottom of the metal part, at this time, the four torque boxes 8 will support the bottom of the metal part around, thereby cooperating with the fixed support component to support the metal part, and play the role of supporting the bottom of the metal part. The four groups of auxiliary support components can each perform independent support adjustment, and cooperate with the indexing actuator 1401 to drive the torque box 8 to rotate and adjust, so that when supporting the metal part, the device can adapt to the support requirements of metal parts of different shapes and metal parts during shearing; When the camera recognition device 4 completes its scanning and detection operation, the system captures the support position, and then the system controls the electric slider 102 to drive the shaft 6 to move relatively within the guide rail 101, thereby causing the electric slider 102 to drive the multiple torque boxes 8 to adjust their positions at the bottom of the metal part, thereby driving the torque boxes 8 to adjust the support position. When the square box 8 finishes supporting the metal part, the electromagnet 503 is driven to pull the magnetic block 502, and the magnetic block 502 will drive the push block 505 to move in the clamping box 5. When the push block 505 moves, the reset spring 504 is elastically retained, and the push block 505 will drive the elastic clamping plate 501 to move through multiple pushing shafts 506. Due to the uneven outer wall of the metal part, when the elastic clamping plate 501 moves to fit the outer wall of the metal part, one end of the elastic clamping plate 501 that fits the outer wall of the metal part will be restricted, and the push block 505 will continue to push. , the elastic clamping plate 501 will slide toward the inside of the clamping box 5 by squeezing the return spring 504 through the moment block 507. When the push block 505 pushes the multiple moment blocks 507 to drive the elastic clamping plate 501 to completely fit the outer wall of the metal part, the outer wall clamping operation of the metal part is completed. The multiple clamping components cooperate with each other to clamp the four sides of the metal part, thereby realizing the clamping operation of the outer wall of the metal part, playing the role of clamping metal parts of different shapes. By working together with the auxiliary support component and the fixed support component, the trinity effect of supporting and fixing metal parts of various shapes can be achieved. The clamping box 5 is connected to the shaft 6 by a connecting rod 602. When the shaft 6 moves upward to drive the moment box 8 to support the bottom of the metal part, the shaft 6 can also drive the clamping box 5 to move upward, so that the position of the clamping assembly can be adjusted according to the upward movement distance of the auxiliary support assembly. When the auxiliary support assembly is raised to any height, the clamping assembly is always placed on one side of the auxiliary support assembly to clamp the outer wall of the metal part, thereby playing the role of synchronous position adjustment. When the laser shear 201 drives the shaft 6 to move, the shaft 6 will drive the clamping box 5 to move together through the connecting rod 602 and the sliding limit rod 12. When the clamping box 5 moves outward, the clamping box 5 will drive the push rod 11 to move through the sliding limit rod 12. The push rod 11 will push the two hinge rods 10 to rotate and open on the shaft block 9. The two hinge rods 10 will hinge and rotate to push the two limit slot rods 1301 to move outward, so that the limit slot rod 1301 pulls the return block spring 1201 through the shift block 13 When the sliding limit rod 12 is moved outward, the two clamping boxes 5 will be moved and adjusted to both sides in the sliding limit rod 12 through the shift block 13. Anyway, when the clamping box 5 moves inward, the two clamping boxes 5 will move inward relative to each other through the shift block 13 due to the elastic pull of the return block spring 1201, so that the distance between the two clamping boxes 5 can be adjusted according to the support point of the shaft rod 6, so that the clamping point between the two clamping components on one side can be adjusted according to the width or length of the metal part, so that the metal part can be better clamped. When the rectangular box 8 moves up to support the bottom of the metal part, the rectangular box 8 will drive the auxiliary support block 801 to move. When the auxiliary support block 801 contacts the outer wall of the metal part, the auxiliary support block 801 will be compressed in the rectangular box 8 to squeeze the pressure spring 803 downward. When the bottom of the auxiliary support block 801 contacts the sensor 802, the rectangular box 8 stops moving up. At this time, the auxiliary support operation of the metal part is completed. Subsequently, the metal part is clamped by the clamping assembly, completing the three-in-one support and retention operation of the metal part. When the laser shear 201 moves to shear the metal part, if the auxiliary support block 801 loses contact with the sensor 802, it means that the metal part has been displaced or deformed. The sensor 802 will control the auxiliary support assembly and the clamping assembly through the system to make relative adjustments, adjust the support position and clamping force, and dynamically support the plate to ensure the stability of the plate during the cutting process, and play a role in detecting whether the metal part is displaced or deformed during the shearing process.
