Description

Technical Field

[0001] This utility model belongs to the field of feeding tray technology, specifically a pneumatic permanent magnet chuck feeding device. Background Technology

[0002] In the field of sheet metal processing, especially in the shearing process of stamping workshops, efficient and safe feeding of steel plates is a key link to ensure a smooth production process. Currently, permanent magnet chucks are widely used in the industry as the core tool for gripping steel plates, working in conjunction with elevators or overhead cranes to achieve vertical lifting and transfer of steel plates. Permanent magnet chucks have become common equipment for handling steel plates (especially medium and heavy-duty plates) in workshops due to their advantages such as requiring no external power to maintain magnetic force, relatively simple structure, low maintenance costs, and strong gripping force.

[0003] When using this device, the operator needs to forcefully turn the mechanical handle or lever on the suction cup to manually drive the magnetic circuit conversion mechanism inside the suction cup (usually a rotating permanent magnet assembly). This causes the magnetic lines of force to penetrate the steel plate, generating a strong suction force to grip the steel plate. After the steel plate is firmly attached, a lift or overhead crane raises the suction cup, raising the steel plate to the desired height or transferring it to the shearing machine's worktable. Once the steel plate is in place, the operator again forcefully turns the handle in the opposite direction to reset the magnetic circuit conversion mechanism, cutting off the magnetic lines of force penetrating the steel plate and releasing it.

[0004] However, this traditional permanent magnet chuck loading method, which relies on manual operation of the handle for magnetization / demagnetization, is problematic in the high-frequency, repetitive work environment of the shearing process. Because each operation requires workers to manually operate the handle, it not only wastes the workers' physical strength, but also poses a risk that their hands may get caught between the chuck handle and the adjacent equipment / steel plate, or other parts of their body may accidentally touch dangerous areas when they are fatigued, distracted, or in a limited operating space. Utility Model Content

[0005] This invention provides a pneumatic permanent magnet chuck feeding device to overcome the deficiencies in the prior art.

[0006] This utility model is achieved through the following technical solution:

[0007] A pneumatic permanent magnet chuck loading device includes two parallel horizontal beams, which are fixedly connected by a vertical beam. A connecting beam is fixedly installed between the two vertical beams and is lifted by a hook of a lifting mechanism. A permanent magnet chuck is fixedly connected to the end of each horizontal beam downwards. A drive gear is fixedly sleeved on the rotating shaft of the permanent magnet chuck. The drive gear meshes with a rack parallel to the vertical beam. The rack is supported by a limiting mechanism and moves synchronously longitudinally under the drive of a pneumatic telescopic rod.

[0008] In use, the lifting mechanism first moves the permanent magnet chuck up and down via connecting beams, vertical beams, and horizontal beams. The permanent magnet chuck is positioned at the four corners for uniform adsorption. During adsorption, the pneumatic telescopic rod is activated, extending to move the rack, which in turn rotates the gears, thus rotating the permanent magnet chuck's rotating shaft and generating suction. Similarly, when placing a steel plate, the pneumatic telescopic rod retracts, rotating in the opposite direction from the rotating shaft to release the magnet. Because the rack drives multiple gears and is driven by the pneumatic telescopic rod, it eliminates the need for manual rotation of the handle and provides better protection for workers.

[0009] Preferably, the limiting mechanism includes a horizontal bar vertically connected to the vertical beam, with the horizontal bar distributed on both the front and rear sides of the vertical beam. A vertical bar is vertically connected to the outer end of the horizontal bar. A strip-shaped rod is fixedly connected to the top surface of the rack along its length. The strip-shaped rod is located between the two vertical bars, and grooves are formed on both sides of the strip-shaped rod. A slider is fitted into the groove, and the slider is fixedly mounted on the corresponding vertical bar. The slider not only supports the groove but also ensures the normal vertical sliding of the strip-shaped rod.

[0010] Preferably, a pneumatic telescopic rod is vertically connected to the middle of one side of the crossbeam. A movable rod is vertically connected to the movable end of the pneumatic telescopic rod. A transverse through-slot is provided in the vertical beam, extending along the length of the vertical beam. The outer end of the movable rod passes through the through-slot and is perpendicularly connected to the strip rod. The extension of the pneumatic telescopic rod causes the movable rod to move, which in turn causes the strip rods on both sides to move synchronously, thereby enabling all permanent magnet chucks to open and close synchronously.

[0011] Preferably, reinforcing ribs are fixedly connected at the connection points between the moving rod and the strip rod, and between the pneumatic telescopic rod and the moving rod. These reinforcing ribs enhance the stability of the connections between the moving rod and the strip rod, and between the pneumatic telescopic rod and the moving rod.

[0012] The beneficial effects of this utility model are as follows: The use of this application can drive all permanent magnet chucks to start and stop through the extension and retraction of the pneumatic telescopic rod, thereby achieving adsorption and release. The rack can drive multiple gears to rotate and the rack is driven by the pneumatic telescopic rod, thus saving the physical strength of the staff to manually rotate the handle, and at the same time achieving better protection of the staff.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] A pneumatic permanent magnet chuck feeding device, such as Figure 1 and Figure 2 As shown, it includes two parallel horizontal beams 1, which are fixedly connected by vertical beams 2. A connecting beam is fixedly installed between the two vertical beams 2, and the connecting beam is lifted by a hook of a lifting mechanism. A permanent magnet chuck 3 is fixedly connected to the end of each horizontal beam 1 downwards. A drive gear 4 is fixedly sleeved on the rotating shaft of the permanent magnet chuck 3. The drive gear 4 meshes with a rack 5 parallel to the vertical beams 2. The rack 5 is supported by a limiting mechanism and moves synchronously longitudinally under the drive of a pneumatic telescopic rod 11.

[0020] In this application, the lifting mechanism is prior art and is not the part that this application seeks to protect; therefore, the use of the lifting mechanism will not be described in detail.

[0021] In use, the lifting mechanism first moves the permanent magnet chuck 3 up and down via the connecting beam, vertical beam 2, and horizontal beam 1. The permanent magnet chuck 3 is positioned at the four corners, ensuring uniform adsorption. During adsorption, the pneumatic telescopic rod 11 is activated. The extension of the pneumatic telescopic rod 11 moves the rack 5, which in turn rotates the gears, thus rotating the rotating shaft of the permanent magnet chuck 3 and generating suction. Similarly, when placing a steel plate, the pneumatic telescopic rod 11 retracts and rotates in the opposite direction from the rotating shaft, releasing the plate. Because the rack 5 can drive multiple gears to rotate and is driven by the pneumatic telescopic rod 11, it eliminates the need for manual rotation of the handle by the operator, while also providing better protection for the operator.

[0022] The limiting mechanism includes a horizontal bar 6 vertically connected to the vertical beam 2. The horizontal bar 6 is distributed on the front and rear sides of the vertical beam 2. The outer end of the horizontal bar 6 is vertically connected to a vertical bar 7. A strip bar 9 is fixedly connected to the top surface of the rack 5 along its length. The strip bar 9 is located between the two vertical bars 7, and grooves are opened on both sides of the strip bar 9. A slider 8 is fitted in the groove and is fixedly mounted on the vertical bar 7 on the corresponding side. A pneumatic telescopic rod 11 is vertically connected to the middle position of one side of the horizontal beam 1. A moving rod 10 is vertically connected to the movable end of the pneumatic telescopic rod 11. A transverse through-groove is opened in the vertical beam 2. The through-groove extends along the length of the vertical beam 2. The outer end of the moving rod 10 passes through the through-groove and is vertically connected to the strip bar 9.

[0023] Among them, the slider 8 not only supports the slide groove, but also ensures the normal vertical sliding of the strip rod 9. The extension of the pneumatic telescopic rod 11 drives the movement of the moving rod 10. The movement of the moving rod 10 drives the strip rods 9 on both sides to move synchronously, thereby realizing the synchronous opening and closing of all permanent magnet chucks 3.

[0024] Reinforcing ribs 12 are fixedly connected at the connection points of the movable rod 10 and the strip rod 9, and at the connection points of the pneumatic telescopic rod 11 and the movable rod 10. The reinforcing ribs 12 can enhance the stability of the connection between the movable rod 10 and the strip rod 9, and between the pneumatic telescopic rod 11 and the movable rod 10.

[0025] The use of this application can drive all permanent magnet chucks 3 to start and stop by extending and shortening the pneumatic telescopic rod 11, thereby achieving adsorption and release. The rack 5 can drive multiple gears to rotate and is driven by the pneumatic telescopic rod 11, thus saving the physical effort of the staff to manually rotate the handle, and at the same time achieving better protection for the staff.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
