[0002] The machining center has evolved from a CNC milling machine. The biggest difference between the machining center and the CNC milling machine is that the machining center has the ability to automatically exchange machining tools and is suitable for processing materials of various lengths. The aluminum machining center is a device specifically used for aluminum processing. It has the characteristics of high precision and high efficiency. It can realize a variety of processes such as cutting, drilling, and milling of aluminum. Through digital control, it ensures the accuracy and consistency of processing, and provides strong support for the production of high-quality aluminum parts in the fields of aerospace, automobile manufacturing, etc.

[0003] In the related art, a machining center for aluminum processing is designed, which includes a workbench, on which a number of clamps for clamping aluminum are bolted, above the clamps are provided with a tool magazine for installing tools for different purposes and a power head for driving the tools for aluminum processing, a guardrail for closing the workbench is provided outside the workbench, and a control console for controlling the power head and the tool magazine is provided outside the guardrail; when in use, various processing functions such as milling, drilling, tapping, and chamfering are realized by installing tools for different purposes on the power head, and during the processing, the guardrail needs to be closed to prevent aluminum chips generated by the processing from splashing out.

[0004] In the process of implementing this application, it was found that there are at least the following problems in this technology: when processing aluminum materials, due to the different specific specifications and sizes of aluminum materials, not all clamps will be used, and unused clamps may interfere with the clamping of the aluminum materials, and these clamps usually need to be removed. In addition, since aluminum materials are processed in a closed environment, debris will splash onto unused clamps. The structure of the clamps is complex and has many grooves. In the process of cleaning the workbench, all clamps need to be cleaned, and the cleaning process is cumbersome. Summary of the invention

[0005] In order to facilitate the storage of unused fixtures, avoid debris splashing onto unused fixtures as much as possible, and reduce the workload of cleaning work, the present application provides a processing center for aluminum materials.

[0006] The present application provides a processing center for aluminum materials using the following technical solutions: A processing center for aluminum materials, comprising a workbench, a plurality of storage grooves are opened on the side walls of the workbench, abutment frames are arranged in the storage grooves, and the abutment frames are fixedly connected to the top wall, bottom wall and two side walls of the storage groove at the same time; a support block is fixedly arranged on the side wall of the workbench, a rotating shaft is rotatably arranged on the support block, a placement plate is fixedly connected to the rotating shaft, a clamp for clamping aluminum materials is fixedly installed on the placement plate, the lower surface of the placement plate is in contact with and abuts against the upper surface of the workbench, a first magnet is embedded and fixedly arranged at the bottom of the placement plate away from the rotating shaft, a second magnet is embedded and fixed on the workbench, and the first magnet and the second magnet attract each other; the placement plate and the clamp can enter the storage groove, the clamp can pass through the center of the abutment frame, and the placement plate can be in contact with and abut against the outer side of the abutment frame.

[0007] By adopting the above technical solution, when it is necessary to process aluminum materials, the placement plate corresponding to the required clamp is rotated from the storage slot and taken out to the workbench. At this time, the first magnet and the second magnet automatically attract each other, which improves the stability of the clamp on the workbench and avoids the lifting of the placement plate by the aluminum material and the clamp when the power head is lifted; the placement plate corresponding to the clamp that is not needed is rotated from the workbench and stored in the storage slot, the clamp passes through the center of the abutment frame, and the placement plate is fitted and abutted against the outside of the abutment frame. At this time, the placement plate closes the storage slot, so that the unused clamps are stored in the storage slot, which is convenient for storing unused clamps. There is no need to frequently disassemble the clamps, and debris is avoided from splashing onto the unused clamps, thereby reducing the workload of cleaning work.

[0008] Preferably, a shielding plate is provided in the storage groove, and the shielding plate is fitted and abutted against the abutment frame.

[0009] By adopting the above technical solution, when the clamp and the placement plate are out of the storage slot, the shielding plate fits and abuts against the abutment frame, thereby closing the inside of the storage slot. The shielding plate prevents aluminum debris from entering the storage slot, so that the inside of the storage slot always remains relatively tidy and clean, and the accumulation and contamination of debris are avoided as much as possible, providing a more ideal space for the subsequent storage of clamps.

[0010] Preferably, the shielding plate is slidably arranged in the storage groove, and a thrust spring is arranged between the shielding plate and the inner wall of the storage groove, one end of the thrust spring abuts against the inner wall of the storage groove, and the other end of the thrust spring abuts against the shielding plate, and the thrust spring drives the shielding plate close to the abutment frame.

[0011] By adopting the above technical solution, when the placement plate and the clamp leave the storage, the shielding plate automatically slides under the action of the thrust spring, and the thrust spring always gives the shielding plate a force toward the abutment frame, so that the shielding plate and the abutment frame fit more closely, further improving the sealing effect of the storage slot, and can better prevent impurities such as aluminum debris from entering the storage slot, thereby enhancing the protection of the storage slot and ensuring the cleanliness of the environment inside the storage slot.

[0012] Preferably, a push rod is connected to the outer side of the shielding plate, the push rod passes through the abutment frame and is slidably engaged with the abutment frame, and the outer end of the push rod can abut against the placement plate.

[0013] By adopting the above technical solution, when the placement plate and the clamp need to be stored in the storage slot, the placement plate will abut against the outer end of the push rod and push the push rod during the rotation process, and the push rod will drive the shielding plate to overcome the elastic force of the thrust spring and slide into the storage slot, thereby making room for the placement plate and the clamp to enter the storage slot; and when the placement plate and the clamp are separated from the storage slot, the thrust spring will push the shielding plate to return to its original position and close the storage slot again, thereby realizing automatic coordination of the storage process.

[0014] Preferably, the push rod is bent along an arc direction, the center of the arc of the push rod coincides with the axis center of the rotating shaft, a supporting shaft is fixedly provided at the inner end of the push rod, a roller is rotatably provided on the supporting shaft, a guide rail groove is opened on the outer side of the baffle plate, and the roller extends into the guide rail groove and rolls with the guide rail groove.

[0015] By adopting the above technical solution, when the placement plate rotates, it will contact and push the push rod. Since the push rod is bent along the arc direction and the center of the circle coincides with the axis of the rotation axis, the movement of the push rod can more smoothly coordinate with the rotation of the placement plate, reducing the relative slip between the push rod and the placement plate, thereby reducing noise and improving the stability and life of the push rod; at the same time, the roller on the support shaft rolls in the guide groove of the shielding plate, reducing friction resistance and making the movement of the push rod more flexible. In this process, the push rod can stably and effectively drive the shielding plate to move, thereby realizing the coordination of the placement plate storage and the shielding plate opening and closing actions, and further optimizing the performance and usage experience of the device.

[0016] Preferably, a lock groove is provided on the side wall of the storage groove, a lock tongue is slidably arranged in the lock groove, a locking spring is provided in the lock groove, one end of the locking spring abuts against the inner wall of the lock groove, and the other end of the locking spring abuts against the lock tongue, the locking spring drives the lock tongue away from the inner wall of the lock groove, and the side wall of the lock tongue can abut against the lower surface of the placement block, and a guide surface is provided on the side of the lock tongue away from the abutment frame, and the placement plate can abut against the guide surface.

[0017] By adopting the above technical solution, when the placement plate moves into the storage slot, the placement plate will first contact and squeeze the guide surface of the lock tongue, thereby pushing the lock tongue to overcome the elastic force of the locking spring and slide into the lock slot. When the placement plate completely enters the storage slot, the lock tongue pops out under the action of the locking spring and abuts against the lower surface of the placement block, thereby locking the placement plate and preventing the placement plate from leaving the storage slot, thereby ensuring the stability of the storage state. When the placement plate needs to be removed, the lock tongue is driven to be pressed into the lock slot to release the lock of the placement plate.

[0018] Preferably, an unlocking shaft is rotatably provided on the side wall of the workbench, one end of the unlocking shaft extends into the lock groove and is fixedly provided with a gear, a rack is fixedly provided on the side wall of the lock tongue, the gear and the rack are meshed with each other, and the other end of the unlocking shaft extends out of the side wall of the workbench and is fixedly provided with a lever.

[0019] By adopting the above technical solution, when it is necessary to unlock the placement plate, the lever can be toggled, and the lever drives the unlocking shaft to rotate, and the gear on the unlocking shaft rotates accordingly, and the engagement with the rack drives the lock tongue to overcome the elastic force of the locking spring and move into the lock groove, thereby realizing the unlocking operation of the lock tongue, making the unlocking process more convenient and quick, and improving the convenience and safety of operation.

[0020] Preferably, the clamp includes a base, a clamping block, a double-threaded screw, and a crank. The base is fixedly mounted on a placement plate, a group of clamping blocks are slidably arranged on the base, and the double-threaded screw is rotatably arranged in the base. One of the clamping blocks is threadedly engaged with one thread segment of the double-threaded screw, and the other clamping block is threadedly engaged with the other thread segment of the double-threaded screw. The crank sleeve is arranged at the end of the double-threaded screw, and the crank is used to drive the double-threaded screw to rotate, and the crank can be detached from the double-threaded screw.

[0021] By adopting the above technical solution, when it is necessary to clamp the aluminum material, the crank is put on the end of the double-threaded screw and the crank is turned. The crank drives the double-threaded screw to rotate. Since the two sections of the double-threaded screw rotate in opposite directions, the two clamping blocks are close to each other to clamp the aluminum material. When the clamp is no longer needed, the crank is removed from the end of the double-threaded screw to improve the space utilization of the storage slot.

[0022] Preferably, the base is fixed to the placement plate by fastening bolts.

[0023] By adopting the above technical solution, the base is fixed to the placement plate by fastening bolts, which ensures the stability and reliability of the fixture during operation. It can not only ensure a tight and firm connection between the base and the placement plate, but also facilitate disassembly and replacement when necessary, thereby increasing the flexibility and maintainability of the entire device.

[0024] Preferably, the side of the placement plate facing away from the clamp and the inner and outer sides of the abutment frame are all covered with rubber pads.

[0025] By adopting the above technical solution, a rubber pad is arranged on the lower surface of the placement plate, which can reduce the wear and collision noise when the placement plate contacts the bottom of the storage groove; the rubber pad on the inner side of the abutment frame can enhance the sealing effect between the abutment frame and the shielding plate, and better prevent impurities from entering the storage groove; the rubber pad on the outer side of the abutment frame can play a buffering role when the abutment frame contacts the placement plate, and improve the sealing effect between the abutment frame and the placement plate, thereby improving the durability and usage experience of the entire device.

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] The present application embodiment discloses a processing center for aluminum materials. Figure 1 The invention comprises a workbench 1, and a plurality of storage slots 2 are provided on the side wall of the workbench 1. An abutment frame 21 is provided in the storage slot 2, and the abutment frame 21 is fixedly connected to the top wall, the bottom wall and the two side walls of the storage slot 2. A plurality of support blocks 3 are fixedly provided on the side wall of the workbench 1, and a rotating shaft 31 is rotatably provided on the support blocks 3, and a placement plate 32 is fixedly connected to the rotating shaft 31, and a clamp 4 for clamping aluminum materials is fixedly installed on the placement plate 32. The side of the placement plate 32 away from the clamp 4, the inner side and the outer side of the abutment frame 21 are all covered with rubber pads.

[0034] Reference Figure 1 and Figure 2 When the clamp 4 needs to be used, the lower surface of the placement plate 32 is attached to and against the upper surface of the workbench 1. The rubber pad on the lower surface of the placement plate 32 helps to reduce the wear and collision noise when the placement plate 32 contacts the workbench 1. A first magnet 321 is embedded and fixedly provided at the bottom of the placement plate 32 away from the rotating shaft 31, and a second magnet 11 is embedded and fixed on the workbench 1. The first magnet 321 and the second magnet 11 attract each other. At this time, the clamp 4 is stably placed on the workbench 1.

[0035] Reference Figure 1 and Figure 3 When the clamp 4 is not needed, the placement plate 32 is rotated, and the placement plate 32 and the clamp 4 can enter the storage groove 2. The clamp 4 passes through the center of the abutment frame 21, and the placement plate 32 fits and abuts against the outside of the abutment frame 21. At this time, the placement plate 32 closes the storage groove 2, and the unused clamp 4 is stored in the storage groove 2. The rubber pad on the outside of the abutment frame 21 plays a buffering role when the abutment frame 21 contacts the placement plate 32, and improves the sealing effect between the abutment frame 21 and the placement plate 32. In this way, debris is avoided from splashing onto the unused clamp 4 as much as possible, the workload of cleaning the unused clamp 4 is reduced, and the cleaning efficiency is improved.

[0036] In order to keep the interior of the storage tank 2 relatively clean at all times, Figure 2 A baffle plate 22 is slidably provided in the storage slot 2, and a thrust spring 221 is provided between the baffle plate 22 and the inner wall of the storage slot 2. One end of the thrust spring 221 abuts against the inner wall of the storage slot 2, and the other end abuts against the baffle plate 22. The thrust spring 221 drives the baffle plate 22 to approach the abutment frame 21, and the baffle plate 22 can fit and abut against the abutment frame 21. When the placement plate 32 and the clamp 4 leave the storage slot 2, the baffle plate 22 automatically abuts against the abutment frame 21 under the action of the thrust spring 221. The rubber pad on the inner side of the frame enhances the sealing effect between the abutment frame 21 and the baffle plate 22. In this way, the baffle plate 22 automatically closes the storage slot 2, preventing impurities such as aluminum debris from entering the storage slot 2, so that the inside of the storage slot 2 always remains relatively clean.

[0037] Reference Figure 1 and Figure 3 , a push rod 211 is connected to the outer side of the shielding plate 22, and the push rod 211 is bent along the arc direction, and the center of the arc of the push rod 211 coincides with the axis center of the rotating shaft 31. The push rod 211 passes through the abutment frame 21 and slides with the abutment frame 21. A support shaft 212 is fixedly provided at the inner end of the push rod 211, and a roller 213 is rotatably provided on the support shaft 212. A guide rail groove 222 is provided on the shielding plate 22, and the roller 213 extends into the guide rail groove 222 and rolls with the guide rail groove 222. When the placement plate 32 rotates, the placement plate 32 will contact the push rod 211 and push the push rod 211 to slide. Since the push rod 211 is bent along the arc direction and the center of the circle coincides with the axis center of the rotating shaft 31, the sliding movement of the push rod 211 is a deflection around the axis center of the rotating shaft 31. The push rod 211 can more smoothly cooperate with the rotation of the placement plate 32, reducing the relative slip between the push rod 211 and the placement plate 32, thereby reducing noise and improving the stability and life of the push rod 211. At the same time, the roller 213 on the support shaft 212 rolls in the guide groove 222 of the shielding plate 22, reducing the friction resistance between the push rod 211 and the shielding plate 22, and the guide groove 222 is located in the storage slot 2, so that debris is not easy to enter the guide groove 222.

[0038] In order to realize the locking and unlocking of the placement plate 32 in the storage slot 2, refer to Figure 3 and Figure 4, a lock slot 12 is provided on the side wall of the storage slot 2, and a lock tongue 121 is slidably provided in the lock slot 12. A locking spring 122 is provided in the lock slot 12, one end of the locking spring 122 abuts against the inner wall of the lock slot 12, and the other end abuts against the lock tongue 121, and the locking spring 122 drives the lock tongue 121 away from the inner wall of the lock slot 12. The side wall of the lock tongue 121 can abut against the lower surface of the placement block. A guide surface 1211 is provided on the side of the lock tongue 121 away from the abutment frame 21, and the placement plate 32 can abut against the guide surface 1211. When the placement plate 32 moves into the storage slot 2, the placement plate 32 first contacts and squeezes the guide surface 1211 of the lock tongue 121, thereby pushing the lock tongue 121 to overcome the elastic force of the locking spring 122 and slide into the lock slot 12. When the placement plate 32 completely passes over the locking groove 12, the locking tongue 121 pops out under the action of the locking spring 122 and abuts against the lower surface of the placement block. At this time, the placement plate 32 is clamped between the locking tongue 121 and the abutting frame 21 to achieve locking of the placement plate 32.

[0039] Reference Figure 3 and Figure 4 The side wall of the workbench 1 is rotatably provided with an unlocking shaft 123, one end of which extends into the lock slot 12 and is fixedly provided with a gear 1231. A rack 1212 is fixedly provided on the side wall of the lock tongue 121, and the gear 1231 and the rack 1212 are meshed with each other. The other end of the unlocking shaft 123 extends out of the side wall of the workbench 1 and is fixedly provided with a lever 1232. When it is necessary to unlock the placement plate 32, the lever 1232 is moved, and the lever 1232 drives the unlocking shaft 123 to rotate, and the gear 1231 on the unlocking shaft 123 rotates accordingly, and the gear 1231 meshes with the rack 1212 and drives the lock tongue 121 to overcome the elastic force of the locking spring 122 and move into the lock slot 12, thereby realizing the unlocking operation of the lock tongue 121.

[0040] In order to improve the space utilization of the storage tank 2, refer to Figure 1 and Figure 2 The clamp 4 includes a base 41, a clamping block 42, a double-threaded screw 43, and a crank 44. The base 41 is fixed to the placement plate 32 by a fastening bolt 45. A group of clamping blocks 42 are slidably arranged on the base 41. The double-threaded screw 43 is rotatably arranged in the base 41, wherein one clamping block 42 is threadedly engaged with one thread segment of the double-threaded screw 43, and the other clamping block 42 is threadedly engaged with the other thread segment of the double-threaded screw 43. The crank 44 is sleeved on the end of the double-threaded screw 43, and the crank 44 is used to drive the double-threaded screw 43 to rotate, and the crank 44 can be detached from the double-threaded screw 43.

[0041] Reference Figure 1 and Figure 2When the aluminum material needs to be clamped or loosened, the crank 44 is placed on the end of the double-threaded screw 43 and the crank 44 is rotated, so that the crank 44 drives the double-threaded screw 43 to rotate, thereby making the two clamping blocks 42 move closer to or farther from each other to clamp or loosen the aluminum material. It is worth noting that when the clamp 4 is not needed, the crank 44 can be removed from the end of the double-threaded screw 43, thereby improving the space utilization of the storage slot 2.

[0042] The implementation principle of a machining center for aluminum materials in the embodiment of the present application is as follows: when the fixture 4 needs to be used, the lever 1232 is toggled, and the lever 1232 drives the unlocking shaft 123 to twist, thereby meshing the gear 1231 and driving the rack 1212 to slide. The lock tongue 121 moves into the lock groove 12, and the lock tongue 121 releases the locking state of the placement plate 32. Then, the thrust spring 221 drives the shielding plate 22 to slide closer to the abutment frame 21, and the shielding plate 22 pushes the placement plate 32 out of the storage groove 2 through the push rod 211, and grabs and rotates the placement plate 32 to the workbench 1. The first magnet 321 and the second magnet 11 attract each other, and at this time the fixture 4 is stably on the workbench 1. After the placement plate 32 is separated from the push rod 211, the thrust spring 221 drives the shielding plate 22 to abut against the abutment frame 21 to close the placement groove.

[0043] When the clamp 4 is not needed, the placement plate 32 is rotated so that the placement plate 32 approaches and enters the storage slot 2. During the process of the placement plate 32 entering the storage slot 2, the placement plate 32 pushes the shielding plate 22 further into the storage slot 2 through the push rod 211 to make room for the clamp 4. The placement plate 32 first contacts and squeezes the guide surface 1211 of the lock tongue 121, pushing the lock tongue 121 to slide into the lock slot 12 against the elastic force of the locking spring 122. When the placement plate 32 completely passes over the lock tongue 121, the lock tongue 121 pops out under the action of the locking spring 122 and abuts against the side of the placement plate 32 away from the clamp 4 to achieve locking. At this time, the placement plate 32 is attached to and abuts against the outside of the abutment frame 21, and the placement plate 32 closes the storage slot 2. It is convenient to store unused clamps 4, try to avoid debris splashing onto unused clamps 4, and reduce the workload of cleaning work.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
