It is also an indispensable preparatory step before the quality inspection of metal parts. In existing shot blasting machines, workpieces are generally transported into the equipment via a conveyor. During the shot blasting process, both the workpiece and the shot blasting equipment maintain a constant orientation. This means that each time a workpiece enters the equipment, only the side closest to the shot blaster can be treated. If shot blasting is required in all directions, the orientation must be repeatedly adjusted and the workpiece reloaded, severely impacting both work efficiency and shot blasting quality. [Utility Model Content]

[0024] Example 1:

[0025] See Figures 1-4 This utility model discloses a metal product surface polishing device, including a shot blasting chamber 1, four shot blasters 2 arranged on one side of the shot blasting chamber 1, and a shot recovery mechanism 7 located at the bottom of the shot blasting chamber 1. A workpiece conveying system is used to transport workpieces into the shot blasting chamber 1. The workpiece conveying system includes a track 3 located on the upper side of the shot blasting chamber 1 and a reciprocating trolley 4 mounted on the track 3. The track 3 extends to the upper side of the shot blasting chamber 1. A hook 5 for suspending workpieces is provided under the trolley 4. A hook rotation mechanism 6 for driving the hook 5 to rotate around its axis is provided between the hook 5 and the trolley 4. In this embodiment, by setting the workpiece conveying system in conjunction with the shot blasting equipment, the workpiece can be automatically transported into the shot blasting equipment for shot blasting. By setting the hook rotation mechanism 6 on the hook 5, the hook rotation mechanism 6 can drive the hook 5 and the workpiece on the hook 5 to rotate together, thereby cooperating with the shot blasters 2 to perform uniform shot blasting treatment on the circumference of the workpiece, improving the processing quality and efficiency.

[0026] For details, please refer to Figure 4 The hook rotation mechanism 6 includes a fixed plate 61, a rotary drive motor 62, and a transmission mechanism 63.

The lifting mechanism 8 is fixedly mounted on the trolley 4 and connected to the upper side of the fixed plate 61 through several slings. The lifting mechanism 8 drives the hook 5 and the workpiece to move up and down vertically, so that the workpiece can be at the optimal height, improving adaptability and processing quality.

[0028] Example 2:

[0029] See Figure 5 , Figure 6 and Figure 7 Based on Embodiment 1, the hook 5 includes a main hook body 51 and a lifting rod 52 connected to the upper end of the main hook body 51. The main hook body 51 is hinged to the lifting rod 52 via a first hinge portion 53. The main hook body 51 can rotate around the first hinge portion 53 in a direction away from or towards the hook opening of the main hook body 51. The main hook body 51 is also provided with an anti-detachment block 54. The middle part of the anti-detachment block 54 is hinged to the main hook body 51 via a second hinge shaft 55. One end of the anti-detachment block 54 is used for... The device has a flipping drive mechanism that cooperates with the inner side of the hook opening to block the hook opening, and extends away from the hook opening at the other end and is provided with a flipping drive mechanism for controlling its flipping around the second hinge axis 55. Specifically, the flipping drive mechanism includes a cable 56, a winch for winding and unwinding the cable 56, and a protective housing 57. The protective housing 57 is fixedly installed on the upper side of the first hinge portion 53 on the boom 52, the winch is installed inside the protective housing 57, and the cable 56 is connected to the anti-detachment block 54. In this embodiment, when the hook 5 is working, the main hook body 51 cooperates with the lifting position on the workpiece, and then the anti-detachment block 54 blocks the hook opening of the main hook body 51, thereby preventing the workpiece from detaching from the main hook body 51. When unloading is required, the winch winds up the cable 56, and the cable 56 drives the anti-detachment block 54 to rise at one end and fall at the other end, so that the end of the anti-detachment block 54 separates from the inside of the hook opening of the main hook body 51, the hook opening of the main hook body 51 opens, and the winch continues to wind up the cable 56, thereby driving the main hook body 51 to also rotate around the first hinge part 53 in a direction away from the hook opening, so that the hook opening faces down, which facilitates unhooking and improves unhooking efficiency.

[0030] Specifically, the second hinge shaft 55 is provided with a first torsion spring for driving the anti-detachment block 54 to rotate in the direction of closing the hook opening. This ensures that the anti-detachment block 54 can remain in the state of blocking the hook opening under normal conditions.
