Description

Technical Field

[0001] This utility model relates to the technical field of machine tool feeding equipment, and specifically to a machine tool feeding device. Background Technology

[0002] Currently, machine tools commonly used for sheet metal processing include laser cutting machines, laser engraving machines, and CNC gantry milling machines. When feeding materials to these machine tools, if the conveying distance is short, a gantry-type sheet metal feeding device is used. The gantry-type sheet metal feeding device is positioned above the machine tool and the material rack, and uses an adsorption mechanism to adsorb the sheet metal and transfer it from the material rack to the machine tool.

[0003] For example, patent CN212449655U discloses a "Slab Loading Device for Machine Tools." This patent discloses a type of gantry-type slab loading device. Specifically, the patent includes a frame, on which are mounted an adsorption mechanism for holding the slab, a lifting mechanism for raising and lowering the adsorption mechanism, and a translation mechanism for moving the adsorption mechanism. The adsorption mechanism includes a crossbeam, several connecting rods, and suction cups. The crossbeam connects to the lifting mechanism, and the connecting rods are vertically mounted on the crossbeam and arranged along its long side. Suction cups are mounted on the connecting rods. In use, the material table (equivalent to a machine tool) and the material rack are both located below the frame. Through the cooperation of the lifting mechanism, translation mechanism, and adsorption mechanism, the slab is moved from the material rack to the material table, realizing the feeding operation.

[0004] Although the above-mentioned device can move the board from the material rack to the machine tool, there is a risk that the board may fall and be damaged if the adsorption mechanism in the device malfunctions during the transfer process due to the board not being firmly adsorbed.

[0005] Therefore, how to reduce the risk of sheet metal falling and improve the safety of material feeding are technical problems that need to be solved. Utility Model Content

[0006] To address the aforementioned shortcomings of existing technologies, this invention proposes a feeding device for machine tools. This invention can reduce the risk of sheet metal falling and improve feeding safety.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A feeding device for a machine tool includes an adsorption mechanism. The adsorption mechanism includes a crossbeam with multiple connecting rods arranged along its long side. The long side of each connecting rod is perpendicular to the long side of the crossbeam. A suction cup is provided on each connecting rod. Fixed plates are provided at both ends of each connecting rod. A trigger rod is vertically slidably connected to the fixed plate. The lower part of the trigger rod is connected to the fixed plate through an elastic element, which is used to push the trigger rod downward. A sliding pin is provided at the top of the trigger rod. Sliding frames are provided at both ends of each connecting rod. The sliding frames are slidably connected to the connecting rod along its long side. An inclined hole is provided at the top of the sliding frame, and the sliding pin is slidably engaged with the inclined hole. A support plate is provided at the bottom of the sliding frame.

[0009] Furthermore, a limiting block is provided at the lower part of the trigger rod, and the elastic element is a spring. The spring is sleeved on the trigger rod, with the upper end of the spring abutting against the bottom surface of the fixing plate and the lower end of the spring abutting against the top surface of the limiting block.

[0010] Furthermore, the bottom of the trigger rod is provided with a trigger disc, the diameter of which is larger than the diameter of the trigger rod.

[0011] Furthermore, the bottom of the trigger disc is provided with a soft pad.

[0012] Furthermore, the side of the connecting rod is provided with a dovetail groove, and the side of the sliding frame is provided with a slide rail, which slides along the long side of the connecting rod in cooperation with the dovetail groove.

[0013] The beneficial effects of this utility model are:

[0014] 1. When the adsorption mechanism picks up the sheet material, the support plate, through the structural cooperation of the fixed plate, trigger rod, elastic element, sliding pin, sliding frame, tilting hole, and support plate, can support the adsorbed sheet material. If the adsorption mechanism malfunctions and the sheet material is not firmly adsorbed, the support plate can prevent the sheet material from falling and being damaged. Therefore, when the adsorption mechanism carries the sheet material to the machine tool, the support plate improves the safety of the feeding process.

[0015] 2. When the support plate supports the plate, it is driven by the cooperation of the fixed plate, trigger rod, elastic element, sliding pin, sliding frame, tilting hole and support plate. It does not require an electric power source. On the one hand, it saves energy, and on the other hand, it avoids the impact of sudden power outages and improves the reliability of preventing the plate from falling.

[0016] 3. By setting a trigger plate at the bottom of the trigger rod, the contact area between the trigger rod and the material rack or the top surface of the machine tool can be increased, thereby improving the stability of the trigger rod against the material rack or the top surface of the machine tool.

[0017] 4. By setting a soft pad at the bottom of the trigger plate, the trigger plate can make soft contact with the material rack or the top surface of the machine tool, reducing the risk of scratching the material rack or the top surface of the machine tool, which helps to protect the material rack or the machine tool and save maintenance costs.

[0039] Example:

[0040] A feeding device for a machine tool includes a frame 1, a translation mechanism, a lifting mechanism, and an adsorption mechanism.

[0041] See Figure 1 The frame 1 is positioned above the material rack 6 and the machine tool 5, and multiple plates 7 are stacked on the material rack 6.

[0042] See Figure 1 , Figure 2 and Figure 3 The translation mechanism includes a guide rail 21, a rack 22, a slide 23, a slider 24, a motor 25, and a gear 26. The guide rail 21 is fixedly installed on the top of the frame 1, and the rack 22 is also fixedly installed on the top of the frame 1. The slider 24 is fixedly installed on the bottom of the slide 23, and the slider 24 slides in cooperation with the guide rail 21. The motor 25, which can be a servo motor, is fixedly installed on the top of the slide 23. The output shaft of the motor 25 passes downward through the slide 23, and the gear 26 is fixedly installed on the output shaft of the motor 25. The gear 26 meshes with the rack 22.

[0043] The working principle of the translation mechanism is as follows: When the motor 25 drives the gear 26 to rotate forward, the gear 26 drives the slide 23 to move from above the material rack 6 to above the machine tool 5; when the motor 25 drives the gear 26 to rotate in reverse, the gear 26 drives the slide 23 to move from above the machine tool 5 to above the material rack 6.

[0044] See Figure 1 , Figure 2 and Figure 3 The lifting mechanism includes a lifting cylinder 31, which is fixedly installed on the top of the slide 23. The piston rod of the lifting cylinder 31 extends downward through the slide 23, and a crossbeam 41 from the adsorption mechanism is fixedly installed on the piston rod of the lifting cylinder 31. In addition to using the lifting cylinder 31, the lifting cylinder 31 can also be replaced by a hydraulic cylinder, an electric push rod, or other telescopic devices.

[0045] The working principle of the lifting mechanism is as follows: When the piston rod of the lifting cylinder 31 extends downward, it pushes the crossbeam 41 downward, causing the crossbeam 41 to move downward; when the piston rod of the lifting cylinder 31 retracts upward, it pulls the crossbeam 41 upward, causing the crossbeam 41 to move upward.

[0046] See Figure 1 , Figure 2 and Figure 3 In addition to the crossbeam 41, the adsorption mechanism also includes connecting rods 42 and suction cups 43. Multiple connecting rods 42 are evenly distributed along the long side of the crossbeam 41, and the long side of the connecting rods 42 is perpendicular to the long side of the crossbeam 41. The connecting rods 42 are fixedly installed on the crossbeam 41, and multiple suction cups 43 are fixedly installed on the connecting rods 42.

[0047] See Figure 1 , Figure 2 and Figure 3 For the connecting rods 42 located at both ends of the crossbeam 41, both ends of the connecting rods 42 are provided with fixing plates 44 and sliding frames 46.

[0048] See Figure 4 and Figure 5A fixing plate 44 is fixedly installed at the end of the connecting rod 42. The fixing plate 44 has a sliding hole 441, within which a trigger rod 45 is installed. The trigger rod 45 slides vertically within the sliding hole 441. A spring 451 is provided at the lower part of the trigger rod 45, and a limit block 452 is also fixedly installed at the lower part of the trigger rod 45. The upper end of the spring 451 abuts against the bottom surface of the fixing plate 44, and the lower end of the spring 451 abuts against the top surface of the limit block 452. The spring 451 pushes the limit block 452 downwards, causing the trigger rod 45 to move downwards within the sliding hole 441. A sliding pin 453 is fixedly installed at the top of the trigger rod 45. A trigger disc 454, with a diameter larger than that of the trigger rod 45, is fixed at the bottom of the trigger rod 45. The bottom of the trigger plate 454 is fitted with a soft pad, which can be made of rubber.

[0049] See Figure 4 and Figure 5 The connecting rod 42 has a dovetail groove 421 on its side, and the sliding frame 46 has a slide rail 461 on its side. The slide rail 461 and the sliding frame 46 are an integral structure, and the slide rail 461 slides in cooperation with the dovetail groove 421 along the long side of the connecting rod 42. The upper part of the sliding frame 46 has an inclined hole 462, the upper end of which faces the middle of the connecting rod 42. The sliding pin 453 slides in cooperation with the inclined hole 462. The bottom of the sliding frame 46 has a support plate 463, which is an integral structure with the sliding frame 46.

[0050] The working principle of this embodiment is as follows:

[0051] (1) The detailed process of suction-lifting board 7 is as follows:

[0052] See Figures 6 to 7 The state changes, the piston rod of the lifting cylinder 31 extends downward, the crossbeam 41 moves downward, and the crossbeam 41 drives the trigger rod 45 to move downward. Figure 7 In the current state, the trigger plate 454 located at the bottom of the trigger rod 45 has just come into contact with the top surface of the material rack 6, and the suction cup 43 has not yet come into contact with the plate 7.

[0053] See Figures 7 to 8As the state changes, the piston rod of the lifting cylinder 31 continues to extend downwards, the crossbeam 41 continues to move downwards, the crossbeam 41 drives the connecting rod 42 to continue moving downwards, the connecting rod 42 drives the fixing plate 44 to continue moving downwards, and the fixing plate 44 begins to compress the spring 451 downwards, the spring 451 gradually accumulates elastic energy. During the process of the fixing plate 44 compressing the spring 451, the spring 451 pushes the limiting block 452 downwards, so that the trigger plate 454 at the bottom of the trigger rod 45 remains in contact with the top surface of the material rack 6, so that the height of the trigger rod 45 remains unchanged, and the trigger rod 45 and the fixing plate 44 slide relative to each other in the vertical direction. The height of the sliding pin 453 at the top of the trigger rod 45 remains unchanged, the connecting rod 42 drives the sliding frame 46 to move downwards, so the upper wall of the inclined hole 462 on the sliding frame 46 is pushed by the sliding pin 453, so that the sliding frame 46 slides horizontally away from the connecting rod 42, and the support plate 463 at the bottom of the sliding frame 46 moves horizontally to the side of the plate 7. Figure 8 In this state, suction cup 43 has not yet come into contact with the board 7.

[0054] See Figures 8 to 9 As the state changes, the piston rod of the lifting cylinder 31 continues to extend downward, and the sliding frame 46 drives the support plate 463 to continue moving away from the plate 7. The suction cup 43 moves down and abuts against the upper surface of the plate 7. At this time, the suction cup 43 is used to adsorb the plate 7.

[0055] See Figures 9 to 10 As the state changes, the piston rod of the lifting cylinder 31 retracts upward, the crossbeam 41 drives the suction cup 43 to move upward, the suction cup 43 adsorbs the plate 7 and moves upward. At the same time, the crossbeam 41 drives the sliding frame 46 to move upward, the spring 451 has a downward pushing force on the limiting block 452, so that the trigger rod 45 keeps in contact with the top surface of the material rack 6, so that the sliding pin 453 at the top of the trigger rod 45 pushes the lower hole wall of the sliding frame 46, so that the sliding frame 46 not only moves upward with the crossbeam 41, but also moves closer to the plate 7.

[0056] See Figures 10 to 11 As the state changes, the piston rod of the lifting cylinder 31 continues to retract upwards, the plate 7 continues to move upwards, and the sliding frame 46 continues to move upwards and approach the plate 7. Figure 11 In the state shown, the support plate 463 at the bottom of the sliding frame 46 moves below the plate 7, so that the plate 7 is supported by the support plate 463 and the plate 7 is prevented from falling.

[0057] See Figures 11 to 12 As the state changes, the piston rod of the lifting cylinder 31 continues to retract upward, the height of the plate 7 is further increased, the trigger plate 454 at the bottom of the trigger rod 45 completely leaves the top surface of the material rack 6, the spring 451 pushes the limit block 452, so that the sliding pin 453 at the top of the trigger rod 45 remains at the lowest end of the inclined hole 462, and the support plate 463 remains in the state of supporting the plate 7.

[0058] (2) The process of releasing plate 7 is as follows:

[0059] The piston rod of the lifting cylinder 31 extends downward, and the crossbeam 41 drives the connecting rod 42, the fixed plate 44, the sliding frame 46, and the trigger rod 45 to move downward. On one hand, the connecting rod 42 drives the suction cup 43 to move downward, and the plate 7 adsorbed by the suction cup 43 moves downward; on the other hand, as the height of the trigger rod 45 decreases, the trigger plate 454 at the bottom of the trigger rod 45 abuts against the top surface of the machine tool 5. After the trigger plate 454 abuts against the top surface of the machine tool 5, the height of the trigger rod 45 remains unchanged. As the crossbeam 41 continues to drive the fixed plate 44 to move downward, the trigger rod 45 slides vertically relative to the sliding hole 441 on the fixed plate 44. Furthermore, as the crossbeam 41 drives the sliding frame 46 to move downward, the sliding pin 453 at the top of the trigger rod 45 pushes the upper wall of the inclined hole 462 on the sliding frame 46, causing the sliding frame 46 to move away from the plate 7. The support plate 463 at the bottom of the sliding frame 46 leaves the plate 7 adsorbed by the suction cup 43, that is, the support plate 463 no longer supports the plate 7. When the support plate 463 is no longer supporting the plate 7, the suction cup 43 releases its grip on the plate 7, and the plate 7 can fall onto the machine tool 5, completing the release process of the plate 7.

[0060] (3) The process of feeding material to machine tool 5 is as follows:

[0061] The translation mechanism moves the lifting mechanism above the material rack 6; the lifting mechanism lowers the height of the adsorption mechanism; the adsorption mechanism adsorbs the topmost plate 7 on the material rack 6; the lifting mechanism raises the adsorption mechanism holding the plate 7, and during the lifting process, the support plate 463 supports the plate 7 to prevent it from falling; the translation mechanism moves the plate 7 from above the material rack 6 to above the machine tool 5, and during the translation process, the plate 7 is supported by the support plate 463; the lifting mechanism lowers the height of the plate 7, and during the lowering process, the support plate 463 gradually moves away from below the plate 7, releasing the support for the plate 7; the adsorption mechanism releases the plate 7 onto the machine tool 5. This completes the process of feeding the material onto the machine tool 5.

[0062] Based on the working principle described above in this embodiment, it can be seen that this embodiment has the following effects:

[0063] First, when the adsorption mechanism picks up the plate 7, the support plate 463 supports the adsorbed plate 7 through the structural cooperation of the fixed plate 44, trigger rod 45, elastic element, sliding pin 453, sliding frame 46, inclined hole 462, and support plate 463. If the adsorption mechanism malfunctions and the plate 7 is not firmly adsorbed, the support plate 463 can prevent the plate 7 from falling and being damaged. Therefore, when the adsorption mechanism carries the plate 7 to the machine tool 5, the support plate 7 can improve the safety of feeding.

[0064] Secondly, when the support plate 463 supports the plate 7, it is driven by the cooperation of the fixed plate 44, the trigger rod 45, the elastic element, the sliding pin 453, the sliding frame 46, the inclined hole 462 and the support plate 463. It does not require an electric power source. On the one hand, it saves energy, and on the other hand, it avoids the impact of sudden power outages and improves the reliability of preventing the plate 7 from falling.

[0065] Third, by setting a trigger plate 454 at the bottom of the trigger rod 45, the contact area between the trigger rod 45 and the top surface of the material rack 6 or the machine tool 5 can be increased, thereby improving the stability of the trigger rod 45 abutting against the top surface of the material rack 6 or the machine tool 5.

[0066] Fourth, by setting a soft pad at the bottom of the trigger plate 454, the trigger plate 454 can make soft contact with the top surface of the material rack 6 or the machine tool 5, reducing the risk of scratching the top surface of the material rack 6 or the machine tool 5, which is beneficial to protecting the material rack 6 or the machine tool 5 and saving maintenance costs.

[0067] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
