Description
Technical Field
[0001] The embodiments disclosed herein relate to the field of shot blasting machine technology, and more specifically, to a hook-type shot blasting machine for a steel plate spring seat. Background Technology
[0002] Hook-type shot blasting machine is a surface treatment device, mainly used to clean and treat dirt, oxide layer, rust and other substances on the surface of metal products. It uses a high-speed rotating shot blasting wheel to spray shot onto the surface of the workpiece to be treated. Through impact and friction, it removes impurities and oxide layer from the surface, making the workpiece surface smooth, improving its quality and corrosion resistance. It can be used for surface treatment of steel plate spring seats. In existing technology, the general workflow of a hook-type shot blasting machine is as follows: A hook lowers and lifts the steel leaf spring seat workpiece, raising it to a certain position before it enters the shot blasting chamber along a track. Upon reaching the predetermined position, the workpiece stops and begins to rotate. At this point, the shot blasting chamber door is closed, the shot blaster is opened, and the shot supply gate is activated. The shot blaster rotates at high speed, propelling shot at high speed and multiple angles onto the surface of the steel leaf spring seat. The shot impacts the workpiece surface, removing oxide scale, rust, dirt, etc., giving the workpiece surface a certain degree of smoothness and roughness. During the cleaning process, the shot and powder... Dust and other particles fall into the bottom screw conveyor and are transported to the shot separator. The separated shot is recycled, while the dust is handled by the dust removal system. However, when multiple steel plate spring seat workpieces are lifted into the shot blasting chamber by hooks for shot blasting, a tray and multiple hooks on the tray are usually used to suspend the multiple workpieces. Since the multiple workpieces are circumferentially suspended under the tray, the multiple workpieces rotate with the tray when it rotates. However, this limits the treatment area of the workpiece surface, which may result in dead corners and make it difficult to completely treat the workpiece surface. Utility Model Content
[0003] To overcome the above-mentioned defects, the embodiments of this disclosure provide a hook-type shot blasting machine for a steel plate spring seat, which solves the technical problem in the prior art that the processing area of the workpiece surface is limited, which may result in processing dead corners and makes it difficult to completely process the workpiece surface.
[0004] According to one aspect, at least one embodiment of this disclosure provides a hook-type shot blasting machine for a leaf spring seat, including a shot blasting machine body. The shot blasting machine body includes a housing, a bracket fixedly connected to the housing, and a hook mechanism provided on the bracket. It also includes a tray, a plurality of rotating rods, and hook attachments. One end of the tray is detachably connected to the hook mechanism via a connecting hook. The plurality of rotating rods are rotatably disposed at the other end of the tray via a drive assembly for driving the plurality of rotating rods to rotate simultaneously. The plurality of hook attachments are rotatably disposed on the rotating rods for fixing the leaf spring seat.
[0005] Preferably, in order to drive multiple rotating rods to rotate simultaneously, the drive assembly includes multiple first rotating shafts, pinions, second rotating shafts, a large gear, and a first motor. A cavity is formed inside the tray. One end of the first rotating shaft is rotatably connected to the inner top wall of the cavity, and the other end is coaxially fixedly connected to one end of each rotating rod. The pinion is fitted onto the outer wall of the first rotating shaft and is coaxially fixedly connected to it. Both ends of the second rotating shaft are rotatably connected to the inner top wall and inner bottom wall of the cavity, respectively. The large gear is fitted onto the second rotating shaft and is coaxially fixedly connected to it. Multiple pinions mesh with the large gear. The first motor is installed at the other end of the tray, and its output end is coaxially fixedly connected to the second rotating shaft.
[0006] Furthermore, in order to hook onto the leaf spring seat and maintain its stability, the hook includes a connecting seat and a placement hook. Multiple sets of connecting seats are fixedly connected to the outer wall of the rotating rod, and each set of connecting seats includes multiple connecting seats. One end of the placement hook is fixedly connected to one end of the connecting seat.
[0007] As a further aspect of this application, in order to enable the multiple rotating rods to drive the leaf spring seat to rotate under the tray while avoiding collision between the leaf spring seat and the box body during rotation, the axis of the second rotating shaft coincides with the axis of the tray.
[0008] As a further improvement in this application, in order to connect the rotating rod to the first rotating shaft, the tray is provided with a plurality of through holes that cooperate with the rotating rod, and the through holes are connected to the cavity.
[0009] Based on the aforementioned solution, in order to avoid damage to the first motor that may be caused when the surface of the steel leaf spring seat is treated inside the box, a protective cover is fixedly connected to the other end of the tray, and the first motor is located inside the protective cover.
[0010] Furthermore, in order to hook the leaf spring seat, the placement hook is V-shaped.
[0011] As a preferred technical solution of this application, in order to prevent the steel plate spring seat from detaching from the placement hook during rotation, the other end of the placement hook is provided with a bending head.
[0012] The beneficial effects of the embodiments disclosed herein are as follows: In this disclosure, through the cooperation of a pallet, multiple rotating rods, a drive assembly, and hooks, the pallet is hooked and stably connected to the bottom end of a hook mechanism via a connecting hook. Subsequently, multiple leaf spring seats are hooked onto a placement hook and transferred into a box for surface treatment via the hook mechanism. A first motor drives multiple rotating rods to rotate simultaneously, and the multiple leaf spring seats on the rotating rods rotate. Thus, while the pallet rotates, the multiple leaf spring seats on the multiple rotating rods rotate around the axis of the rotating rods. This allows for comprehensive cleaning of the leaf spring seat surface, avoiding blind spots that could lead to poor surface treatment results. After treatment, the leaf spring seats can be easily removed from the placement hook. Attached Figure Description

[0022] like Figures 1-6As shown, this invention discloses a hook-type shot blasting machine for a leaf spring seat according to an embodiment of the present invention. The machine includes a shot blasting machine body 1, which includes a housing 2. The leaf spring seat 7 is located inside the housing 2 and can be surface-treated. A shot blasting device is installed inside the housing 2. By using a high-speed rotating impeller, centrifugal force is used to propel shot at high speed onto the surface of the leaf spring seat 7 to achieve a cleaning function. A bracket 3 is fixedly connected to the housing 2. A hook mechanism 4 is installed on the bracket 3 for suspending a tray 5, which can lift and transport the workpiece into the housing 2 and make the workpiece rotate inside the housing 2. The machine also includes a tray 5, multiple rotating rods 6 and hooks. One end of the tray 5 is detachably connected to the hook mechanism 4 through a connecting hook 20. By moving the tray 5, the connecting hook 20 is connected to the bottom end of the hook mechanism 4. The hook mechanism 4 can drive the tray 5 to rotate and move into the housing 2. like Figure 5 As shown, multiple rotating rods 6 are rotatably mounted on the other end of the tray 5 via a drive assembly, used to drive the multiple rotating rods 6 to rotate simultaneously. To enable simultaneous rotation of the multiple rotating rods 6, the drive assembly includes multiple first rotating shafts 8, pinions 10, second rotating shafts 11, a large gear 12, and a first motor 13. A cavity 9 is formed inside the tray 5. One end of the first rotating shaft 8 is rotatably connected to the inner top wall of the cavity 9, and the other end is coaxially fixedly connected to one end of the rotating rod 6. To connect the rotating rod 6 to the first rotating shaft 8, multiple through holes 16 are formed on the tray 5 to mate with the rotating rod 6, and the through holes 16 communicate with the cavity 9. A pinion 10 is fitted onto the outer wall of the first rotating shaft 8 and is coaxially fixedly connected to it. The two ends of the second rotating shaft 11 are rotatably connected to the inner top wall and inner bottom wall of the cavity 9, respectively. The large gear 12 is fitted onto the second rotating shaft 11 and coaxially fixedly connected to it. All the pinions 10 mesh with the large gear 12. In order to enable multiple rotating rods 6 to drive the leaf spring seat 7 to rotate under the tray 5, and to prevent the leaf spring seat 7 from colliding with the box 2 during rotation, the axis of the second rotating shaft 11 is coincident with the axis of the tray 5. The first motor 13 is installed at the other end of the tray 5, and the output end of the first motor 13 is coaxially and fixedly connected to the second rotating shaft 11. In order to avoid damage to the first motor 13 when the surface of the leaf spring seat 7 is treated inside the box 2, a protective cover 17 is fixedly connected to the other end of the tray 5. The first motor 13 is inside the protective cover 17. By starting the first motor 13, the output end of the first motor 13 rotates and drives the second rotating shaft 11 to rotate. The rotation of the second rotating shaft 11 drives the large gear 12 to rotate. The rotation of the large gear 12 drives multiple small gears 10 to rotate simultaneously. The rotation of the multiple small gears 10 drives multiple first rotating shafts 8 to rotate respectively. The rotation of the multiple first rotating shafts 8 drives multiple rotating rods 6 to rotate simultaneously. like Figure 3 and Figure 4As shown, multiple hooks are rotatably mounted on the rotating rod 6 for fixing the leaf spring seat 7. To hook and hold the leaf spring seat 7 and maintain its stability, the hooks include connecting seats 14 and placement hooks 15. Multiple sets of connecting seats 14 are fixedly connected to the outer wall of the rotating rod 6. These sets of connecting seats 14 are evenly distributed longitudinally on the rotating rod 6, and each set includes multiple connecting seats 14. These connecting seats 14 are evenly and circumferentially distributed on the outer wall of the rotating rod 6. One end of the placement hook 15 is fixedly connected to one end of the connecting seat 14. To hook and hold the leaf spring seat 7, the placement hook 15 is V-shaped. To prevent the leaf spring seat 7 from being... During rotation, the plate spring seat detaches from the placement hook 15. The other end of the placement hook 15 is provided with a bending head 18. Since the plate spring seat 7 itself has a through hole 19 in the middle, the other end of the placement hook 15 is passed through the through hole 19 by holding the plate spring seat 7. Since the placement hook 15 is V-shaped, the plate spring seat 7 can be hooked on the placement hook 15. The bending head 18 can protect the plate spring seat 7 and prevent it from detaching from the placement hook 15 during rotation. The rotating rod 6 drives multiple connecting seats 14 to rotate, and the connecting seats 14 drive the placement hook 15 to rotate, thus driving the plate spring seat 7 to rotate. Working Principle: The hook-type shot blasting machine for the leaf spring seat 7 is placed in a suitable position. Before surface treatment of the leaf spring seat 7, with the bottom of the hook mechanism 4 in a low position, the tray 5 is hooked and stably connected to the bottom of the hook mechanism 4 via the connecting hook 20. Multiple leaf spring seats 7 are then hooked onto the placement hook 15. The hook mechanism 4 then drives the tray 5 upwards, which in turn moves the rotating rod 6 and multiple leaf spring seats 7 upwards, opening the housing 2. The hook mechanism 4 drives the tray 5 to transfer into the housing 2. The shot blasting equipment drives the impeller to rotate at high speed, using centrifugal force to propel the shot at high speed onto the surface of the leaf spring seat 7. Simultaneously, the hook mechanism 4 drives the tray 5 to rotate horizontally, cleaning the surface of the leaf spring seats 7 hooked onto the placement hook 15. During this process, the machine is started... The first motor 13 drives the second rotating shaft 11 to rotate, which in turn drives the large gear 12 to rotate. The large gear 12 then drives multiple small gears 10 to rotate simultaneously. These small gears 10 then drive multiple first rotating shafts 8 to rotate, which in turn drive multiple rotating rods 6 to rotate simultaneously. The rotating rods 6 drive multiple connecting seats 14 to rotate, and the connecting seats 14 drive the placement hooks 15 to rotate. This, in turn, drives the leaf spring seats 7 to rotate. As the tray 5 rotates, the leaf spring seats 7 on the multiple rotating rods 6 rotate around the axis of the rotating rods 6. This allows for a thorough cleaning of the surface of the leaf spring seats 7, avoiding blind spots that could lead to poor surface treatment. After cleaning, the leaf spring seats 7 can be easily removed from the placement hooks 15.
