The viewing window 106 facilitates observation of the situation inside the machine body 101.

[0033] Referring to Figure 4, there are two assembly trays 2, which are rotatably mounted on opposite side walls of the body 101. One of the assembly trays 2 has a motor 3 mounted on its shaft end. The motor 3 is mounted on the outer side wall of the body 101 via a mounting base 107. The motor 3 can drive the corresponding assembly tray 2 to rotate.

[0034] Referring to Figures 2 to 7, there are two clamping assemblies, which are respectively assembled on the corresponding assembly plate 2. The clamping assembly includes a base 401 and a clamping member. The base 401 is assembled on the assembly plate 2. The base 401 is provided with a threaded part 402. A prism 405 is provided at the center of the threaded part 402. A prism 404 is inserted into the prism 405. A mounting plate 403 is provided at one end of the prism 404, so that the mounting plate 403 is clamped at one end of the base 401 by the cooperation of the prism 404 and the prism 405.

[0035] A threaded sleeve 406 is screwed into the threaded part 402. The threaded part 402 and the threaded sleeve 406 are connected by threads and have self-locking performance. Multiple retaining plates 407 are arranged on the peripheral side wall of the mounting plate 403 by an array of screws 408. Each retaining plate 407 is provided with a retaining groove 409. Each retaining groove 409 is engaged with the threaded sleeve 406. After the mounting plate 403 is engaged at one end of the base 401 by the cooperation of the prism 404 and the prism hole 405, the retaining plates 407 are assembled on the peripheral side wall of the mounting plate 403 by screws 408, and the retaining grooves 409 on each retaining plate 407 are engaged with the threaded sleeve 406, so that the mounting plate 403 can be locked and fixed.

[0036] Referring to Figures 5 to 7, a clamping component is provided on the mounting plate 403. The clamping component includes a mounting groove 501 provided on one side of the mounting plate 403. A fixing plate 502 is provided in a through groove of the mounting groove 501. A bidirectional screw 503 is rotatably provided between a groove of the mounting groove 501 and the fixing plate 502. The two helices on the bidirectional screw 503 are in opposite directions. A handwheel 504 is provided at one end of the bidirectional screw 503.

[0037] Each of the two slide blocks 505 is screwed into the corresponding threaded portion of the bidirectional screw 503 located in the mounting groove 501. Each slide block 505 is equipped with a clamping block 506. When the bidirectional screw 503 is rotated by rotating the handwheel 504, the two slide blocks 505 can move relatively closer / away on the corresponding helical portion of the bidirectional screw 503, thereby making the distance between the two clamping blocks 506 adjustable. The two clamping blocks 506 on the same mounting plate 403 can be used to clamp the outer periphery of one end of the shaft, and finally the end of the shaft is clamped by the clamping blocks 506, so that the shaft is clamped and installed in the machine body 101.

[0038] Referring to Figures 2 to 4, when the motor 3 is started, the assembly plate 2, base 401, mounting plate 403, clamping block 506 and shaft can be rotated, causing the shaft clamped and installed inside the machine body 101 to rotate.

[0039] Referring to Figures 3 and 4, the sandblasting pipe assembly is located above the back plate of the machine body 101. The sandblasting pipe assembly includes a T-shaped pipe 601 installed above the back plate of the machine body 101. The port of the T-shaped pipe 601 located outside the machine body 101 can be connected to the sandblasting pipe of the sandblasting machine, so that the sandblasting is introduced into the T-shaped pipe 601. The T-shaped pipe 601 is provided with multiple branch pipes 602, and each branch pipe 602 is provided with a flexible pipe 603. Each flexible pipe 603 has a nozzle 604 at its end. When the sandblasting is introduced into the T-shaped pipe 601, the sandblasting can enter the corresponding nozzle 604 through each branch pipe 602 and flexible pipe 603, and then be sprayed towards the surface of the rotating shaft to perform sandblasting treatment on the surface of the shaft.

Each through slot 701 has a connecting rod 703 connected to it via a hinged post 702. The connecting rods 703 can swing within the through slots 701. A pulling rod 704 is hinged between the top of the two connecting rods 703, and a locking rod 705 is hinged between the bottom of the two connecting rods 703. Each nozzle 604 is arrayed and locked within the locking rod 705. The combination of the two connecting rods 703, the pulling rod 704, and the locking rod 705 forms a parallelogram structure. A second motor 706 is located on the top of the machine body 101. A crank 707 is installed on the drive shaft. A pull rod 708 is hinged to one end of the crank 707. One end of the pull rod 708 is hinged to the middle of the traction rod 704. When the starter motor 706 drives the crank 707 to rotate, the pull rod 708 drives the traction rod 704 to move back and forth. After being driven by the two connecting rods 703, the clamping rod 705 can move back and forth, causing the nozzles 604 clamped on the clamping rod 705 to swing back and forth. This enables the rotating shaft to be blasted by reciprocating swinging sandblasting, thus eliminating the need for workers to hold the spray gun in one hand and flip the workpiece in the other to blast the workpiece, thereby improving production efficiency.

[0041] Referring to Figure 4, the bottom of the machine body 101 is a bucket-shaped part 102. The bottom of the bucket-shaped part 102 is provided with a discharge pipe 103. The bucket-shaped part 102 can collect the sandblasted sand used and then discharge it back into the sandblasting machine through the discharge pipe 103.
