The hook can be driven to rotate by driving motor 1, and four identical cylinders can push the movable frame to move downward, which is convenient for changing the height of the high-pressure nozzle. The output shaft of driving motor 2 can drive the transmission gear to rotate through the rotating shaft, and the transmission gear can drive the driven gear and the high-pressure nozzle to rotate, which is convenient for controlling the rotation of multiple high-pressure nozzles, and can better perform shot blasting. The collection trough and shot collection drawer of the fixed box below the shot blasting room can collect the shot blasting, and the vacuum cleaner can suck out the dust inside the fixed box and the shot blasting box through the connecting pipe.

[0004] However, it was found during use that the workpiece to be processed was placed inside the device only by hanging. During the shot blasting process, the suspended workpiece might be knocked down due to a large impact force, resulting in poor stability.

[0005] In the prior art, the utility model with authorization announcement number CN217801142U is named: a hook shot blasting machine, which is equipped with a shot blasting machine body, a movable door, a first motor, a guide frame, a screw, a movable plate, a telescopic rod, a connecting frame, a support plate, a second motor, a driving shaft, a driving gear, a supporting shaft, a planetary carrier, a driven shaft, a driven gear and a hook. It is beneficial to drive the hooks of different angles to rotate by one motor, which is beneficial to the all-round shot blasting work after the hook drives the workpiece to rotate.

[0006] However, the above device still cannot solve the problem that the suspended workpiece may be impacted and fall, and has poor stability. Utility Model Content

DETAILED DESCRIPTION

[0025] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example 1

[0027] like Figure 1 to Figure 4 As shown, this embodiment proposes a shot blasting machine that is easy to position, including a shot blasting box 1, a shot blasting machine body 2 and a positioning mechanism 3. The positioning mechanism 3 includes a positioning box 301 fixedly connected to the inner top wall of the shot blasting box 1, and a rotating rod 302 is rotatably sleeved on the inner top wall of the positioning box 301. The two ends of the rotating rod 302 respectively pass through the shot blasting box 1 and the positioning box 301.

[0028] The upper and lower ends of the rotating rod 302 are respectively fixedly connected with a worm wheel 303 and a disc 304 . When the worm wheel 303 rotates, the disc 304 is driven to rotate through the rotating rod 302 .

[0029] A servo motor 313 and a worm 314 are installed on the upper surface of the shot blasting box 1. The output shaft end of the servo motor 313 is fixedly connected to the rotating shaft end of the worm 314. The worm 314 is meshed with the worm wheel 303. When the servo motor 313 is started, the worm 314 will be driven to rotate, and the rotation of the worm 314 can drive the worm wheel 303 and the rotating rod 302 to rotate.

[0030] The worm wheel 303 and the worm 314 are combined to have the effect of deceleration and self-locking, and can limit the rotation state of the rotating rod 302. If the rotating rod 302 is to rotate, it can only be achieved by rotating the worm 314, and the rotating rod 302 cannot drive the worm 314 to rotate in the reverse direction.

[0031] The bottom surface of the disk 304 is hinged with two connecting rods 305 through a pin shaft. The inner top wall sliding sleeve of the positioning box 301 is provided with two sliders 306. The positions of the two sliders 306 are as follows: Figure 4 As shown, the two sliders 306 are hinged to the two connecting rods 305 respectively.

[0032] When the disk 304 rotates, the two sliders 306 can move toward or away from each other through the two connecting rods 305 .

[0033] The bottom surfaces of the two sliders 306 are fixedly connected with the first positioning plate 307 and the second positioning plate 308 respectively, the outer surfaces of the first positioning plate 307 and the second positioning plate 308 are respectively provided with the first positioning groove 309 and the second positioning groove 311, and the side surfaces of the first positioning plate 307 and the second positioning plate 308 close to each other are fixedly connected with the first positioning rod 310 and the second positioning rod 312 respectively.

[0034] The outer surfaces of the first positioning plate 307 and the second positioning plate 308 are respectively slidably connected to the two reserved grooves opened on the bottom surface of the positioning box 301, the size of the first positioning rod 310 is consistent with the second positioning groove 311, and the size of the first positioning groove 309 is consistent with the second positioning rod 312. By limiting the relationship between the sizes of the above structures, stable positioning work can be performed on different workpieces to avoid falling.

[0035] When the two sliders 306 move toward or away from each other, the device can specifically suspend and position the workpiece. The two sliders 306 move toward each other, allowing the first positioning rod 310 and the second positioning rod 312 to respectively penetrate into the top of the workpiece, and then be inserted into the second positioning groove 311 and the first positioning groove 309 respectively to suspend and position the workpiece. In this way, the workpiece will not be accidentally dropped due to impact force, thereby improving the positioning effect.

[0036] Example 2

[0037] like Figure 1 to Figure 4 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes that two shot blasting machine bodies 2 are respectively installed on both sides of the shot blasting box 1, and the two shot blasting machine bodies 2 are both located below the positioning box 301. By limiting the position of the shot blasting machine body 2, it is convenient to perform shot blasting on the workpiece suspended below the positioning box 301.

[0038] The shot blasting machine body 2 is an existing mechanism, and the working principle and internal structure of the shot blasting machine body 2 are not within the scope of innovation in this application, so the shot blasting machine body 2 will not be described in detail.

[0039] A detachable collecting frame 4 is installed on the inner wall of the shot blasting box 1. The collecting frame 4 is located directly below the positioning box 301. The collection frame 4 can be used to collect the ejected shots.

[0040] A box door 5 is installed on the front of the shot blasting box 1, and a handle is fixedly connected to the outer surface of the box door 5. The box door 5 can play a protective role and facilitate safer shot blasting of the workpiece inside the shot blasting box 1.

[0041] Six universal wheels 6 are fixedly connected to the bottom surface of the shot blasting box 1, and a limiting mechanism is arranged inside each universal wheel 6. By arranging the universal wheels 6, the device can be flexibly moved, and it is convenient to push the device to a suitable position for shot blasting.

[0042] An electric push rod 7 is installed at the bottom of the shot blasting box 1, and the output end of the electric push rod 7 is fixedly connected to a support plate 8, and the bottom surface of the support plate 8 is fixedly connected to an anti-slip pad 9. By arranging the electric push rod 7, the support plate 8 and the anti-slip pad 9, the device can be more stably positioned at a specified position for easy use.

[0043] Working principle: when in use, the top of the workpiece is placed between the first positioning rod 310 and the second positioning rod 312, and then the servo motor 313 is driven to work. When the servo motor 313 is working, the worm 314 can be driven to rotate, and the rotation of the worm 314 can drive the worm wheel 303 to rotate. When the worm wheel 303 rotates, the disc 304 can be driven to rotate through the rotating rod 302, and the two connecting rods 305 can be used to make the two sliders 306 move closer to each other, so that the first positioning plate 307 and the second positioning plate 308 can move closer to each other, thereby driving the first positioning rod 310 and the second positioning rod 312 to move closer to each other. The first positioning rod 310 and the second positioning rod 312 will pass through the top of the workpiece respectively, and then be inserted into the second positioning groove 311 and the first positioning groove 309 respectively, to realize the hanging positioning of the workpiece, so that the workpiece will not accidentally fall due to the impact force when it is shot peened through the shot blasting machine body 2, thereby achieving a more convenient and stable positioning effect.

[0044] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
