Description

Technical Field

[0001] This invention relates to the field of aluminum alloy furniture raw material sheet production technology, and more specifically, to a cutting device for aluminum alloy furniture production and processing. Background Technology

[0002] Cutting devices for the production and processing of aluminum alloy furniture raw material sheets refer to mechanical equipment and tools specifically designed for cutting, forming, and processing aluminum alloy materials during furniture manufacturing.

[0003] Existing cutting devices are usually equipped with only one type of saw blade. When different aluminum alloy furniture cutting tasks are required, different types of saw blades need to be changed. This requires disassembling the equipment and manually removing and installing the required type of saw blade with the help of tools. However, using manual tools for disassembly and installation requires stopping the equipment first and then removing the saw blade. If there are multiple different cutting tasks, the machine needs to be stopped multiple times to change the saw blade, which increases the overall aluminum alloy furniture cutting and processing time and reduces cutting efficiency.

[0004] Furthermore, when aluminum alloy furniture raw material sheet cutting has not been performed for a long time and the cutting task needs to be performed again, the staff needs to get close to the equipment to check the type of saw blade and verify that the type of saw blade to be cut is consistent with the requirements. At the same time, they manually drip lubricating oil onto the rotating part of the saw blade. However, manually dripping lubricating oil may result in missing or over-lubricating, which may damage the cutting saw blade and prevent it from rotating normally for cutting work. This also increases the preparation time before the overall aluminum alloy furniture cutting.

[0005] To solve the above problems, the inventors proposed a cutting device for the production and processing of aluminum alloy furniture. Summary of the Invention

[0010] Preferably, the outer wall of the operating table is provided with transparent glass, the cutting track is adapted to the saw blade, and the telescopic end of the electric telescopic rod is fixedly connected to the slide plate.

[0011] Preferably, the slide plate is "T" shaped, the first connecting rod is rotatably connected to the slide plate, the pushing column is adapted to the inner groove, the second connecting rod is rotatably connected to the slide plate, and the dividing plate is rotatably connected to the limiting plate.

[0012] Preferably, the fixed plate has an indicator light on the side away from the square plate, which is the same as the number of saw blades, and the outer wall of the fixed plate is fixedly connected with partitions at equal intervals, which is the same as the number of saw blades.

[0013] Preferably, the skateboard is provided with a fixing component, the fixing component including a gear speed increaser fixedly connected to the skateboard, a support plate fixedly connected to the side of the skateboard near the gear speed increaser, a reciprocating screw rotatably connected to the side of the support plate near the skateboard, a moving plate threadedly connected to the reciprocating screw, a trigger block and a drive motor fixedly connected to the moving plate, a second engagement post fixedly connected to the output shaft of the drive motor, and a guide rod fixedly connected to the side of the support plate near the skateboard.

[0014] Preferably, the fixing assembly further includes a first synchronous wheel fixedly connected to the output shaft of the servo motor, a second synchronous wheel fixedly connected to the input shaft of the gear speed increaser, the second synchronous wheel being driven by the first synchronous wheel, a third synchronous wheel fixedly connected to the output shaft of the gear speed increaser, and a fourth synchronous wheel fixedly connected to the outer surface of the reciprocating lead screw, the fourth synchronous wheel being driven by the third synchronous wheel.

[0015] Preferably, the reciprocating lead screw is rotatably connected to the slide plate, the moving plate is slidably connected to the guide rod, the second biting post is adapted to the first biting post, and the guide rod is fixedly connected to the slide plate.

[0016] Preferably, the slide plate is provided with a lubrication assembly, which includes a piston cylinder fixedly connected to a support plate. The piston cylinder has a dropper 1 and a dropper 2 connected inside. A return spring is symmetrically fixedly connected to the side of the piston cylinder near the trigger block. There are no fewer than two return springs. The end of the return springs away from the piston cylinder is fixedly connected to a connecting plate.

[0017] Preferably, the piston cylinder has a liquid inlet on its surface, the end of the first dropper away from the piston cylinder points to the rotating hole, the end of the second dropper away from the piston cylinder points to the output shaft of the drive motor, and the connecting plate is fixedly connected to the piston rod of the piston cylinder.

[0018] As described above, the advantages of this invention are:

[0019] By rotating the column one full turn, the dividing disc rotates 90 degrees, thus enabling the switching of different types of saw blades. Compared to existing technologies that require manual disassembly and reassembly of the equipment and saw blades, this device integrates four different types of saw blades on a square plate. When it is necessary to switch saw blades, the different types of saw blades can be switched by rotating the column, avoiding the traditional disassembly and installation process, significantly reducing equipment downtime. Furthermore, since the square plate carries different types of saw blades, each saw blade can handle different cutting tasks, such as cutting aluminum alloys of different shapes or details, increasing the flexibility of the processing environment.

[0020] By observing the indicator lights below the saw blades within the cutting track through the transparent glass of the operating table, the type of saw blade in the cutting track can be determined. Compared to existing technologies, where operators need to approach the equipment to check the type of saw blade and verify its compatibility when aluminum alloy cutting is needed again after a long period of inactivity, this device utilizes indicator lights below the saw blades. Operators can quickly identify the type of saw blade simply by observing the color of the indicator light, avoiding the safety hazards caused by operators approaching the equipment to check the saw blade type. This improves operational safety and effectively adapts to cutting different materials, avoiding the cumbersome steps of cutting on multiple cutting devices. Furthermore, by switching between different saw blades, a series of cutting tasks can be effectively performed according to the situation, such as chamfering and trimming.

[0021] By moving the movable plate, the torque of the drive motor output shaft can be transmitted before and after switching saw blades. Compared with the existing technology, which requires manual installation of saw blades with tools, this device uses the meshing of the teeth between the second and first biting pins to achieve automatic assembly after saw blade switching. This avoids positioning errors or operational mistakes caused by manual reinstallation of the saw blade, such as improper tightening or misalignment, which would reduce the cutting quality. In this way, through the meshing and disengagement of the teeth between the second and first biting pins, the replaced saw blade can be driven by the drive motor normally for cutting, avoiding the possibility of human error during the manual replacement and disassembly of the saw blade.

[0022] By moving the connecting plate, the rotating shaft and the output shaft of the drive motor can be lubricated. Compared with the existing technology where lubricating oil is manually dripped after the saw blade is changed, this device lubricates the rotating connection between the rotating shaft and the rotating hole, as well as the output shaft of the drive motor, during the saw blade switching process. There is no need to stop the machine for manual maintenance, which reduces downtime. Moreover, the amount of lubricating oil added each time is fixed, avoiding various problems caused by manual lubrication, such as missing or over-lubricating. In this way, after the saw blade is switched, the saw blade can rotate smoothly and normally to complete the cutting of aluminum alloy furniture. Attached Figure Description

[0046] Furthermore, such as Figure 7As shown, the fixed plate 515 has an indicator light on the side away from the square plate 510, which is the same number as the number of saw blades 514.

The four partitions are located between two adjacent saw blades 514 respectively.

[0047] Furthermore, such as Figures 8 to 10 As shown, a fixing assembly is provided on the slide plate 51. The fixing assembly includes a gear speed increaser 61 fixedly connected to the slide plate 51. The gear speed increaser 61 is located on the side of the slide plate 51 near the servo motor 52 and above the servo motor 52. A support plate 62 is fixedly connected to the side of the slide plate 51 near the gear speed increaser 61. The support plate 62 is L-shaped and located above the gear speed increaser 61.

[0050] During work:

[0051] The staff uses a conveying device to transport the aluminum alloy furniture raw material sheet to the surface of the workbench 1, and controls the extension and retraction of the electric telescopic rod 4 through the controller, which drives the slide plate 51 to move horizontally along the slide rail 3, thereby driving the saw blade 514 to move horizontally along the cutting track 2. The rotation of the saw blade 514 is used to cut the aluminum alloy furniture raw material sheet.

[0052] This device allows you to switch between different types of saw blades 514 as needed. Detailed steps are as follows:

[0053] When it is necessary to switch the type of saw blade 514, the operator first controls the output shaft of the drive motor 65 to a low speed state via the controller. Then, the operator controls the output shaft of the servo motor 52 to rotate one revolution. The connecting rod 53 rotates together with the output shaft of the servo motor 52. The connecting rod 53 drives the limiting plate 54 to rotate one revolution. During the rotation of the limiting plate 54, the pushing column 56 rotates in a circle at the eccentric position of the limiting plate 54. During this process, the limiting plate 54 gradually enters the inner groove 59 opened on the surface of the dividing plate 58 according to the rotation angle. When the pushing column 56 enters the inner groove 59 opened on the surface of the dividing plate 58, the outer ring of the dividing plate 58... The surface of the push post 56 disengages from the outer arc surface of the limiting disk 54, allowing the push post 56 to enter the inner groove 59. The push post 56 then pushes the dividing disk 58 to rotate. At this point, the inner groove 59 closest to the push post 56 is pushed to the position of the previous inner groove 59. Before the limiting disk 54 has completed one revolution, the limiting disk 54 continues to rotate, causing the push post 56 to rotate and disengage from the inner groove 59. The limiting disk 54 continues to rotate until the push post 56 has completed one revolution. At this point, the dividing disk 58 rotates ninety degrees, and the arc surface of the dividing disk 58 is in contact with the outer surface of the limiting disk 54, so that the dividing disk 58 remains stationary after rotation.

[0054] The rotation of the dividing disc 58 causes the square plate 510 to rotate together with the dividing disc 58, so that the next saw blade 514 and the indicator light on the fixed plate 515 rotate to the position of the previous saw blade 514 and indicator light. This means that the operator can control the output shaft of the servo motor 52 to drive the push column 56 to rotate three times, so that the three inner grooves 59 can be replaced accordingly and rotated into the cutting track 2 in sequence. By observing the indicator light under the saw blade 514 through the transparent glass on the outer wall of the operating table 1, it can be determined which type of saw blade 514 is in the cutting track 2. At the same time, by pushing the column 56 to drive the intermittent rotation of the dividing disc 58 to replace the saw blade 514, the purpose of effectively and accurately replacing different saw blades 514 is achieved, avoiding the inaccuracy of the position of the saw blade 514 after replacing it by other methods.

[0055] In the above process, by pushing the column 56 to rotate one revolution, the dividing plate 58 is driven to rotate ninety degrees, thereby realizing the switching of different types of saw blades 514. Compared with the existing technology, which requires manual disassembly of the equipment and then disassembly and installation of the saw blades 514, this device integrates four different types of saw blades 514 on the square plate 510. When it is necessary to switch saw blades 514, the different types of saw blades 514 can be switched by pushing the column 56 to rotate, avoiding the traditional disassembly and installation process, significantly reducing equipment downtime. Furthermore, since the square plate 510 is equipped with different types of saw blades 514, each saw blade 514 can handle different cutting tasks, such as cutting aluminum alloys of different shapes or details, increasing the flexibility of the processing environment.

[0056] In the above process, by observing the indicator light below the saw blade 514 in the cutting track 2 through the transparent glass of the outer wall of the operating table 1, the type of saw blade 514 in the cutting track 2 can be determined. Compared with the prior art, when there has been no aluminum alloy cutting task for a long time and it is necessary to perform aluminum alloy cutting task again, the operator needs to get close to the equipment to check the type of saw blade 514 and check whether the type of saw blade 514 to be cut is consistent with the requirements. This device uses indicator lights set below the saw blade 514. The operator only needs to observe the color of the indicator light to quickly determine which type of saw blade 514 is installed. This avoids the safety accident caused by the operator getting close to the equipment to check the type of saw blade 514. In this way, the safety of operation is improved. At the same time, it can effectively adapt to the cutting of different materials, avoid the cumbersome steps of cutting on multiple cutting equipment, and by switching different saw blades 514, a series of cutting tasks can be effectively performed according to the situation, such as chamfering, trimming materials, etc.

[0057] This device can be installed simultaneously after switching the type of saw blade 514. The detailed steps are as follows:

[0058] During the rotation of the dividing disc 58 by 90 degrees, the synchronous pulley 68 on the output shaft of the servo motor 52 drives the synchronous pulley 69 to rotate together via the synchronous belt, making the output shaft of the servo motor 52 and the input shaft of the gear speed increaser 61 rotate at the same speed. Through the gear speed increaser 61, the output shaft of the gear speed increaser 61 rotates faster than the input shaft of the gear speed increaser 61. Since the synchronous pulley 610 on the output shaft of the gear speed increaser 61 drives the synchronous pulley 611 to rotate together via the synchronous belt, and the synchronous pulley 611 is located on the outer surface of the reciprocating lead screw 63, the output shaft of the gear speed increaser 61 and the reciprocating lead screw 63 rotate at the same speed. As a result, the speed of the reciprocating lead screw 63 is faster than the output shaft of the servo motor 52.

[0059] During the process of pushing column 56 rotating half a circle, but not entering the inner groove 59, moving plate 64 moves horizontally along guide rod 67 in the direction away from square plate 510. Since the teeth of biting column 2 66 and biting column 1 513 are designed with bevels, biting column 2 66 can be smoothly disengaged from biting column 1 513, so that the original tight meshing state between biting column 1 513 and biting column 2 66 is no longer formed.

[0060] When the push column 56 enters the inner groove 59, the moving plate 64 continues to move horizontally along the guide rod 67 in the direction away from the square plate 510 until the push column 56 has rotated half a turn. At this time, the moving plate 64 moves to the other end of the guide rod 67. When the push column 56 begins to rotate the remaining half turn, the moving plate 64 moves horizontally along the guide rod 67 in the direction closer to the square plate 510.

[0061] When the push post 56 leaves the inner groove 59, the moving plate 64 continues to move horizontally along the guide rod 67 towards the side closer to the square plate 510. At this time, the square plate 510 is stationary. As the moving plate 64 continues to move horizontally, the rotating engagement post 66 contacts its corresponding engagement post 513, causing the teeth of engagement post 66 to contact the teeth of engagement post 513. Since the teeth of engagement post 66 and engagement post 513 are designed with bevels, this provides guidance for the engagement of engagement post 66 and engagement post 513. During this process, the edges of engagement post 66 and engagement post 513 first contact to form a contact point. The moving plate 64... As the horizontal movement continues, the contact points between the second biting post 66 and the first biting post 513 gradually increase until the push post 56 rotates the remaining half turn. At this point, the moving plate 64 moves back to the initial position, and the second biting post 66 and the first biting post 513 form a complete mesh, so that the torque of the output shaft of the drive motor 65 can be transmitted to the first biting post 513, causing the first biting post 513 to rotate together with the output shaft of the drive motor 65. This further causes the rotating shaft 512 and the saw blade 514 to rotate together with the output shaft of the drive motor 65. Then, the operator can increase the speed of the output shaft of the drive motor 65 through the controller, and then use the switched saw blade 514 to cut the aluminum alloy furniture raw material board.

[0062] In the above process, the transmission of torque of the output shaft of the drive motor 65 before and after switching the saw blade 514 can be realized by moving the moving plate 64. Compared with the existing technology, which requires manual installation of the saw blade 514 with the help of tools, this device uses the mutual meshing of the teeth between the second biting post 66 and the first biting post 513 to realize the automatic assembly of the saw blade 514 after switching. This avoids positioning errors or operational mistakes caused by manual reinstallation of the saw blade 514, such as improper tightening or misalignment, which would reduce the cutting quality. In this way, through the meshing and disengagement of the teeth between the second biting post 66 and the first biting post 513, the replaced saw blade 514 can be normally driven by the drive motor 65 to cut, thus avoiding the possibility of human error during the disassembly process of manually replacing the saw blade 514.

[0063] Example 2: Further, such as Figure 11 and Figure 12 As shown, a lubrication assembly is provided on the slide plate 51. The lubrication assembly includes a piston cylinder 71 fixedly connected to the support plate 62. The piston cylinder 71 is connected to a dropper 1 72 and a dropper 2 73. A reset spring 74 is symmetrically fixedly connected to the side of the piston cylinder 71 near the trigger block 6401. There are no fewer than two reset springs 74. The end of the reset spring 74 away from the piston cylinder 71 is fixedly connected to a connecting plate 75.

[0064] Furthermore, such as Figure 11 and Figure 12 As shown, the piston cylinder 71 has a liquid inlet on its surface. The operator pours lubricating oil into the piston cylinder 71 through the liquid inlet. The end of the dropper 72 away from the piston cylinder 71 points to the rotating connection between the rotating shaft 512 and the rotating hole 511, and the end of the dropper 72 away from the piston cylinder 71 is directly above the rotating shaft 512. The end of the dropper 73 away from the piston cylinder 71 points to the output shaft of the drive motor 65, and the end of the dropper 73 away from the piston cylinder 71 is directly above the output shaft of the drive motor 65. The connecting plate 75 is fixedly connected to the piston rod of the piston cylinder 71.

[0065] During operation: This device can be used to switch saw blade 514 and perform lubrication. The detailed steps are as follows:

[0066] Referring to Embodiment 1, as the moving plate 64 moves horizontally away from the square plate 510 along the guide rod 67, the trigger block 6401 gradually moves away from the connecting plate 75, causing the return spring 74 to gradually return to its normal state. As the moving plate 64 moves horizontally towards the square plate 510 along the guide rod 67 and returns to its initial position, the trigger block 6401 pushes the connecting plate 75, causing the return spring 74 to become compressed. At the same time, the piston rod of the piston cylinder 71 moves towards the side closer to the square plate 510, thereby pushing the lubricating oil in the piston cylinder 71 to the first dropper 72 and the second dropper 73. The lubricating oil drips through the first dropper 72 to the rotating connection between the rotating shaft 512 and the rotating hole 511, and through the second dropper 73 to the output shaft of the drive motor 65. Since the compression length of the return spring 74 is fixed, the amount of lubricating oil dripped each time is also fixed, so that after switching to different types of saw blades 514, the saw blade 514 can rotate smoothly, thereby performing the cutting work of aluminum alloy furniture.

[0067] During the above process, the rotating shaft 512 and the output shaft of the drive motor 65 can be lubricated by moving the connecting plate 75. Compared with the prior art, which involves manually dripping lubricating oil after manually changing the saw blade 514, this device lubricates the rotating connection between the rotating shaft 512 and the rotating hole 511, as well as the output shaft of the drive motor 65, during the process of switching the saw blade 514. This eliminates the need for manual maintenance and reduces downtime. Furthermore, the amount of lubricating oil added each time is fixed, avoiding various problems caused by manual lubrication, such as missing or over-lubricating. As a result, after switching the saw blade 514, the saw blade 514 can rotate smoothly and normally to complete the cutting of aluminum alloy furniture.

[0068] The above are merely embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
