[0021] In order to solve the technical problem of how the rotating shaft drives the workpiece to rotate, please refer to Figures 1-3 The embodiment provides the following technical scheme:

[0022] A rotary shot blasting machine hanger tool, comprising a top plate 1 and a bearing plate 2, a center shaft 3 is supported between the top plate 1 and the bearing plate 2, the side end of the center shaft 3 is rotatably provided with a rotating shaft 4, the number of rotating shafts 4 is multiple, and the rotating shafts 4 are arranged in a ring array about the center shaft 3, and the rotating shaft 4 is provided with a hook 43 for fixing the workpiece.

[0023] The lower surface of the bearing plate 2 is provided with a motor 23 through a motor box 22, the output end of the motor 23 is fixedly connected with an internal gear 24, the bottom of the rotating shaft 4 is welded with an external gear 25 engaged with the internal gear 24, and the external gear 25 and the internal gear 24 are rotatably arranged in the bearing plate 2.

[0024] Specifically, when the shot blasting machine starts to work, the motor 23 is started, the motor 23 drives the internal gear 24 to rotate, since the bottom of the rotating shaft 4 is welded with the external gear 25 engaged with the internal gear 24, and the external gear 25 and the internal gear 24 are rotatably arranged in the bearing plate 2, the rotation of the internal gear 24 drives the external gear 25 to rotate, and the rotation of the external gear 25 directly drives the rotating shaft 4 connected therewith to rotate, and the rotating shaft 4 is provided with a hook 43 for fixing the workpiece, the workpiece is stably fixed by the hook 43, so that the rotating shaft 4 rotates, the hook 43 also rotates synchronously, and the workpiece mounted on the hook 43 rotates, in the process of shot blasting, the workpiece rotates continuously, so that the steel shots can impact the surface of the workpiece from multiple directions, thereby achieving the effect of uniform shot blasting.

[0025] In order to solve the technical problem of how to adjust the position of the hook, please refer to Figure 4 The embodiment provides the following technical scheme:

[0026] A plurality of shaft sleeves 42 are slidably connected to the rotating shaft 4, a plurality of hooks 43 are annularly arranged and welded to the outer surface of the shaft sleeve 42, and adjusting holes 41 are equidistantly formed in the rotating shaft 4, and the shaft sleeve 42 is fixed to the adjusting hole 41 in the rotating shaft 4 through a double-headed bolt 44.

[0027] Specifically, when it is necessary to adjust the position of the hook 43 on the rotating shaft 4, first, the double-headed bolt 44 is unscrewed, the double-headed bolt 44 originally fixes the shaft sleeve 42 in the adjusting hole 41 in the rotating shaft 4, since the shaft sleeve 42 is slidably connected to the rotating shaft 4, after the double-headed bolt 44 is unscrewed, the shaft sleeve 42 can slide along the rotating shaft 4, according to the shape, size of the workpiece and the specific requirements of the shot blasting process, the shaft sleeve 42 is slid to the appropriate position, so that the hooks 43 annularly arranged and welded to the outer surface of the shaft sleeve 42 are in an ideal layout state, then the double-headed bolt 44 is inserted through the shaft sleeve 42 and the corresponding adjusting hole 41 in the rotating shaft 4, and the double-headed bolt 44 is tightened, so that the shaft sleeve 42 is fixed to the rotating shaft 4 again, thus the adjustment of the position of the hook 43 is completed, and the position of the hook 43 can be flexibly adjusted in this way to adapt to the mounting requirements of different types of workpieces.

[0028] As shown in Figures 1-2 The upper surface of the top plate 1 is welded with a lifting ring 11.

[0029] It should be noted that the lifting ring 11 provides a convenient lifting connection point for the entire hanger tool.

[0030] As shown in Figure 1 The top plate 1 is provided with a through groove 12 for steel shots to pass through.

[0031] It should be noted that the through groove 12 provides an unobstructed passage for the steel shots, allowing them to pass smoothly through the top plate 1 to the surface of the workpiece below.

[0032] As shown in Figure 2 The upper surface of the bearing plate 2 is fixedly installed with a conical plate 21, which is movably connected with the lower end of the rotating shaft 4 through a bearing, and the upper end of the rotating shaft 4 is movably connected with the top plate 1 through a bearing.

[0033] It should be noted that the shape of the conical plate 21 helps guide the flow of steel shots. During the shot blasting process, the steel shots will be ejected and dispersed around the workpiece. The conical structure of the conical plate 21 can cause the steel shots to naturally disperse or slide around after hitting its surface, avoiding the accumulation of steel shots above the bearing plate 2.

[0034] Working principle: The hanger tool of the rotary shot blasting machine is used. First, adjust the position of the hook 43 according to the shape and size of the workpiece, unscrew the double-headed bolt 44, and make the shaft sleeve 42 slide on the rotating shaft 4. After sliding the shaft sleeve 42 to the appropriate position, use the double-headed bolt 44 to pass through the shaft sleeve 42 and the adjusting hole 41 and tighten it to fix the shaft sleeve 42. Mount the workpiece on the hook 43, use the lifting ring 11 to lift the hanger tool with the mounted workpiece, then hoist it to the designated position inside the shot blasting machine for installation. After installing the hanger tool, start the shot blasting machine, the steel shots are ejected from the launcher, and reach the workpiece surface through the through groove 12. At this time, start the motor 23, which drives the inner gear 24 to rotate. Since the outer gear 25 is meshed with the inner gear 24, the inner gear 24 can drive the outer gear 25 to rotate, and then drive the rotating shaft 4 and the hook 43 to rotate. The hook 43 drives the workpiece to rotate with the rotating shaft 4. With the rotation of the rotating shaft 4, the workpiece constantly changes its position and angle, so that the steel shots from all directions can uniformly hit the surfaces of the workpiece, avoiding the problem of insufficient shot blasting on some surfaces and excessive shot blasting on other surfaces caused by the fixed workpiece in traditional hanger tools.
