Description

Technical Field

[0001] This utility model relates to the field of shot blasting machine hook technology, specifically an adjustable hook for shot blasting machines. Background Technology

[0002] In the metal processing industry, shot blasting is a commonly used surface cleaning and strengthening technology. First, the workpiece to be processed is fixed to a hook. Then, a moving mechanism drives the hook and the workpiece to move inside the shot blasting machine. At the same time, the high-speed projectiles impact the surface of the workpiece, removing impurities such as oxide scale, rust, and oil, improving the surface roughness and adhesion of the workpiece, and providing a good foundation for subsequent processing or coating processes.

[0003] Currently, most existing shot blasting machine hooks are fixed, one-piece structures. Although the workpiece can be processed by rotating the hanger after it is hung, only the outer side of the workpiece can be processed, while the inner side cannot be effectively processed, which easily leads to processing dead zones. Furthermore, the existing shot blasting machine hook structure cannot adjust the rotation of the workpiece during processing to ensure that the outer surface of the workpiece is effectively processed, which has certain shortcomings. Therefore, we propose an adjustable hook for shot blasting machines. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an adjustable hook for shot blasting machines, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable hook for a shot blasting machine, comprising an upper fixed frame and a lower fixed frame. A mounting cover is fixedly installed at the bottom of both the upper and lower fixed frames. A square tube is fixedly installed at the bottom of each mounting cover. One end of one square tube is fixedly connected to the top of the lower fixed frame. An mounting cavity is provided inside each mounting cover. A drive gear is rotatably installed inside each of the two mounting cavities. A linkage shaft is rotatably installed inside the square tube. Both ends of the linkage shaft are fixedly connected to the middle of the two drive gears. Several rotating shafts are rotatably installed inside the mounting cover. A driven gear is fixedly installed on the outer side of each rotating shaft, meshing with the drive gear. One end of each rotating shaft extends to the outer side of the bottom of the mounting cover and is fixedly fitted with an upper hook.

[0006] Furthermore, a movable sleeve plate is installed on the outer side of the square tube, and locking screws are threaded on the inside of both sides of the movable sleeve plate. A knob is fixedly installed at one end of the locking screw, and an anti-slip locking block is fixedly installed at the other end of the locking screw. The anti-slip locking block cooperates with the square tube, and several rotating hooks are rotatably installed on the top of the movable sleeve plate.

[0007] Furthermore, a drive motor is fixedly installed on the top of the upper fixed frame, and the output end of the drive motor is fixedly connected to the middle of a drive gear.

[0008] Furthermore, a limiting plate is fixedly installed at one end of another of the square tubes.

[0009] Furthermore, a mounting bracket is fixedly installed on the top of the upper fixed frame and on the outside of the drive motor, and a connecting ring is fixedly installed on the top of the mounting bracket.

[0010] Furthermore, the movable sleeve has a square hole in the middle that mates with the square tube.

[0011] This utility model provides an adjustable hook for a shot blasting machine, which has the following advantages:

[0012] This shot blasting machine uses an adjustable hook. Through the arrangement of a drive gear, a linkage shaft, a rotating shaft, and a driven gear, when the workpiece is hung for post-processing, the drive motor drives the drive gear to rotate. The two drive gears rotate simultaneously through the transmission of the linkage shaft. The drive gear meshes with the driven gear, thereby driving the rotating shaft and the upper hook to rotate. This allows the upper hook and the hung workpiece to rotate, thus adjusting different processing surfaces for processing and avoiding the occurrence of processing dead zones.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Please see Figures 1 to 4 This utility model provides a technical solution: an adjustable hook for a shot blasting machine, including an upper fixed frame 1 and a lower fixed frame 2. A mounting cover 3 is fixedly installed at the bottom of both the upper fixed frame 1 and the lower fixed frame 2. A square tube 4 is fixedly installed at the bottom of each mounting cover 3. One end of one square tube 4 is fixedly connected to the top of the lower fixed frame 2. A mounting cavity 5 is opened inside the mounting cover 3. A drive gear 6 is rotatably installed inside each of the two mounting cavities 5. A linkage shaft 7 is rotatably installed inside the square tube 4. The two ends of the linkage shaft 7 are fixedly connected to the middle of the two drive gears 6 respectively. Several rotating shafts 8 are rotatably installed inside the mounting cover 3. A fixedly installed shaft 8 is mounted on the outer side of each rotating shaft 8. There is a driven gear 9, which meshes with the driving gear 6. One end of the rotating shaft 8 extends to the outer side of the bottom of the mounting cover 3 and is fixedly installed with an upper hook 10. The workpiece to be processed is hung through the upper hook 10. During the processing of the workpiece, when the drive motor 11 drives one driving gear 6 to rotate, it can drive another driving gear 6 to rotate synchronously through the linkage shaft 7. Thus, the driving gear 6 meshes with the driven gear 9 and drives the rotating shaft 8 and the upper hook 10 to rotate, so that several hung workpieces rotate in the same direction. This plays a role in adjusting the workpiece processing surface, ensuring the effect of shot blasting machine on workpiece processing, and avoiding the occurrence of processing dead corners.

[0020] A movable sleeve plate 12 is installed on the outer side of the square tube 4. Locking screws 13 are threaded on both sides of the movable sleeve plate 12. A knob 14 is fixedly installed at one end of the locking screw 13, and an anti-slip locking block 15 is fixedly installed at the other end of the locking screw 13. The anti-slip locking block 15 cooperates with the square tube 4. Several rotating hooks 16 are rotatably installed on the top of the movable sleeve plate 12. With the arrangement of the movable sleeve plate 12, locking screws 13, knobs 14, anti-slip locking blocks 15 and rotating hooks 16, when the workpiece is hung on the upper hook 10, the workpiece can be hung below by rotating hooks 16. Then, by adjusting the height of the movable sleeve plate 12 on the outer side of the square tube 4, the workpiece can be pulled downward by rotating hooks 16, thereby ensuring the stability of the workpiece during shot blasting.

[0021] A drive motor 11 is fixedly installed on the top of the upper fixed frame 1, and the output end of the drive motor 11 is fixedly connected to the middle of a drive gear 6. The drive motor 11 can be powered by a mobile power supply set on the top of the upper fixed frame 1, so as to ensure that the power supply to the drive motor 11 is adjusted by the upper hook 10 to rotate when the upper fixed frame 1 is driven to rotate by the shot blasting machine.

[0022] A limiting plate 17 is fixedly installed at one end of another square tube 4; the limiting plate 17 can limit the movable sleeve 12 below the lower fixed frame 2.

[0023] A mounting bracket 18 is fixedly installed on the top of the upper fixed frame 1 and on the outside of the drive motor 11. A connecting ring 19 is fixedly installed on the top of the mounting bracket 18. The mounting bracket 18 is used to improve the installation and fixation of the drive motor 11. The connecting ring 19 can be connected to the shot blasting machine connecting bracket mechanism.

[0024] The movable sleeve 12 has a square hole in the middle that mates with the square tube 4. By opening the hole in the movable sleeve 12 that mates with the square tube 4, the movable sleeve 12 can slide on the outside of the square tube 4 to adjust its position and height, so that the rotating hook 16 can apply a downward pulling force to the workpiece and fix the workpiece.

[0025] In summary, this shot blasting machine uses an adjustable hook. During use, first, the workpiece to be processed is hung on the upper hook 10. Then, rotating the knob 14 causes the locking screw 13 and the movable sleeve 12 to be connected via threads, displacing the anti-slip locking block 15 from contact with the square tube 4. Next, the height of the movable sleeve 12 is adjusted so that the rotating hook 16 fixes the workpiece from below. Then, the position of the movable sleeve 12 is lowered, causing the rotating hook 16 to move downwards and apply a downward pulling force to the workpiece. Finally, rotating the knob 14 again causes the locking screw 13 to move via threads, displacing the anti-slip locking block 15 to contact the square tube 4 and fix the movable sleeve 12. The entire assembly is moved into the shot blasting machine via the connecting ring 19, and then the workpiece can be processed. During the process, the shot blasting machine drives the upper fixed frame 1 and the lower fixed frame 2 to rotate, treating the outer surface of the workpiece. Then, during the process, the drive motor 11 is turned on, which drives one drive gear 6 to rotate and simultaneously drives another drive gear 6 to rotate synchronously through the linkage shaft 7. This allows the drive gear 6 to mesh with the driven gear 9, driving the rotating shaft 8 and the upper hook 10 to rotate, thus rotating the workpiece. This serves to regulate the rotation and ensure that the workpiece rotates 360° for processing, avoiding any dead angles in the processing.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
