Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figure 1-5 As shown, the utility model provides a multi-station intermittent CNC shot blasting machine, including a revolving door 20, a turntable assembly, a rotary drive mechanism and two drive transmission mechanisms. The turntable assembly is mounted on the revolving door 20, and the rotary drive mechanism is connected to the revolving door 20 to drive the revolving door 20 to rotate, and the revolving door 20 drives the turntable assembly to rotate. The turntable assembly is equipped with at least two turntables 7, and the two drive transmission mechanisms are both mounted on the turntable assembly. The drive transmission mechanism is connected to the turntable 7 to drive the turntable 7 to rotate.

[0023] The rotary drive mechanism includes a servo motor 1, a planetary reducer 2 and a rotating shaft 4. The output shaft of the servo motor 1 is connected to the planetary reducer 2, and the planetary reducer 2 is connected to the rotating shaft 4 through an expansion coupling 3. The revolving door 20 is mounted on the rotating shaft 4. The servo motor 1 and the planetary reducer 2 cooperate to drive the rotating shaft 4 to rotate, so that the rotating shaft 4 drives the revolving door 20 to rotate around its central axis. The turntable assembly includes two rotating plates 5 respectively arranged on both sides of the revolving door 20, and the two rotating plates 5 are tightly connected to the revolving door 20 and rotate together with the revolving door 20. There are a total of six turntables 7, which are respectively arranged at the upper ends of the rotating plates 5 on both sides. Two driving transmission mechanisms are respectively arranged at the bottom of the rotating plates 5 on both sides. One of the driving transmission mechanisms is connected to three of the turntables 7. The driving transmission mechanism includes a driving member and a transmission assembly. The driving member is connected to the transmission assembly, and the transmission assembly is connected to the turntable 7. The driving member drives the transmission assembly to operate and causes the transmission assembly to link the three turntables 7 to rotate synchronously. The bottom of the turntable 7 is equipped with a transmission shaft 8 for connecting to the transmission assembly, and The bottom of the rotating plate 5 is equipped with a protective cover 6 that wraps the transmission assembly inside it. The transmission assembly includes a driving wheel 16, a driven wheel 18, a synchronous pulley 9 and a synchronous belt 12. The driven wheel 18 is installed on the transmission shaft 8 through a bearing seat 13. The output shaft of the driving member is connected to the driving wheel 16. The driving wheel 16, the driven wheel 18 and the synchronous pulley 9 are connected by a synchronous belt 12. The driving member drives the driving wheel 16 to rotate, and drives the synchronous pulley 9 and the driven wheel 18 to rotate synchronously with the driving wheel 16 through the synchronous belt 12, so that the driven wheel 18 drives the turntable 7 to rotate along its central axis. During the rotation of the revolving door 20, the six turntables 7 mounted on the rotating plate 5 are driven to rotate, and the driving transmission mechanism drives the respective connected turntables 7 to rotate, so that the product can rotate continuously during the shot peening process. The shot peening equipment performs shot peening on the rotating product. Due to the continuous rotation of the product, the shot peening particles can evenly cover the entire surface of the product, thereby improving the processing efficiency and processing quality, and realizing simultaneous processing and uniform shot peening of multiple products.

[0024] When the revolving door 20 is closed and in the initial position, the staff places a product to be shot blasted on each of the three turntables 7 on the rotating plate 5 on one side of the revolving door 20 (called the "loading side"). The rotary drive mechanism is started, driving the revolving door 20 to rotate slowly, and bringing the rotating plate 5 loaded with products into the shot blasting room. At this time, the turntable 7 on the rotating plate 5 on the other side (called the "unloading side") is idle, ready to receive the next batch of products to be shot blasted. Once the revolving door 20 completely brings the rotating plate 5 on the loading side into the shot blasting room, the shot blasting operation begins, and the products are shot blasted. While the shot blasting operation is in progress , the staff places new products to be shot blasted on the rotating plate 5 on the unloading side to prepare for the next rotation of the revolving door 20. When the shot blasting operation is completed, the rotary drive mechanism is started again and the revolving door 20 is rotated in the opposite direction to rotate the rotating plate 5 in the shot blasting room (now carrying products that have completed the shot blasting) out to the unloading side. On the unloading side, the staff can safely remove the processed products from the turntable 7 and carry out subsequent operations or move them to the next process. As the revolving door 20 continues to rotate, the rotating plates 5 on both sides alternately enter and exit the shot blasting room, forming a continuous and efficient product shot blasting process;

[0025] A waist hole 14 is provided on the side of the rotating plate 5 close to the driving wheel 16. The transmission assembly also includes a tension adjustment assembly mounted on one side of the driving wheel 16.

The tensioning wheel 10 is provided on the tensioning wheel shaft 11 and is rotatably connected thereto. The tensioning wheel 10 is in contact with the synchronous belt 12. The adjusting bolt 19 passes through the adjusting plate 15 and is bolted to the rotating plate 5 to fix the position of the tensioning wheel 10. By adjusting the adjusting bolt 19, the position of the adjusting plate 15 on the rotating plate 5 can be changed, thereby adjusting the contact pressure between the tensioning wheel 10 and the synchronous belt 12 to ensure that the tension of the synchronous belt 12 is moderate to prevent slipping or excessive wear.

During the rotation of the revolving door 20, the six turntables 7 mounted on the rotating plate 5 are driven to rotate, and two driving transmission mechanisms are mounted on the turntable assembly, and the driving transmission mechanism is connected to the turntable 7 to drive the turntable 7 to rotate. The staff places the product on the turntable 7, and the driving transmission mechanism drives the turntable 7 to rotate, so that the product can continue to rotate during the shot peening process.
