DETAILED DESCRIPTION

[0023] Please see the attached Figure 1 -Attached Figure 4 The present invention provides a cannonball simulation rotation device, comprising a simulation box 1, wherein a cannonball body 2 is vertically arranged inside the simulation box 1, a driving box 3 is fixed to the bottom surface of the simulation box 1, and the cannonball body 2 is fixed in position by a plurality of vertically distributed fixing components 202, and rotates in the simulation box 1 by the driving of the rotating component under the action of the driving box 3;

[0024] The fixing assembly 202 includes a fixing frame, which includes a fixing bearing 206 and fixing rods 205 symmetrically arranged on both sides of the fixing bearing 206, and each fixing rod 205 is provided with a fixing hole; a pair of adjusting screw rods 201 are vertically arranged inside the simulation box 1, and the fixing holes on the fixing rods 205 cooperate with the adjusting screw rods 201, so that the fixing frame is assembled to the adjusting screw rods 201.

[0025] The bottom of the adjusting screw rod 201 is assembled on the top plate of the driving box 3 , and the top of the adjusting screw rod 201 passes through the top plate of the simulation box 1 and is connected to the first driving mechanism 204 .

[0026] Specifically, a snap ring 203 is mounted on the outer wall of the projectile body 1. The snap ring 203 is connected to the inner race of the fixed bearing 206 in the mounting bracket. For example, the snap ring 203 can be assembled into the inner race of the fixed bearing 206 by means of an interference fit. The internal shape of the snap ring 203 is adapted to the projectile body 1, for example, it has a conical structure. The snap ring 203 is used for mounting the projectile body 1 and the fixed bearing 206. By using snap rings of different specifications, projectile bodies 1 of different outer diameters can be adapted to smoothly fit into the fixed bearing 206. The mounting bracket uses the fixed bearing 206 to restrict and support the position of the projectile body 1, while also allowing the projectile body 1 to rotate within the fixed bearing 206.

[0027] Preferably, a rubber ring 5 is provided between the snap ring 203 and the shell body 1. Through the design of the rubber ring 5, a tight connection is achieved between the snap ring 203 and the outer wall of the shell body 1, thereby increasing the friction between the two and avoiding slipping, so that the shell body 1 can be better connected to the fixed bearing 206.

[0028] Optionally, the first driving mechanism 204 includes a support frame arranged on the top of the simulation box 1, a first motor is installed on the support frame, and a first driving gear is installed on the output shaft of the first motor; a first driven gear is installed on the top of the adjusting screw 201, and the first driving gear and the first driven gear are connected by a chain; wherein the thread on the adjusting screw 201 is a bidirectional thread, that is, the upper thread and the lower thread are rotated in opposite directions; a pair of fixing components 202 are provided, which are respectively installed on the upper and lower parts of the adjusting screw 201 by using threaded holes ; When the first motor drives the adjusting screw 201 to rotate in different directions through the first driving gear and the first driven gear, the pair of adjusting screws 201 approach or move away; when moving away, the gap between the pair of adjusting screws 201 increases, and the shell body 1 can be replaced and placed at this time; after the shell body 1 is placed, the pair of adjusting screws are driven closer. During this process, the outer wall of the clamping ring 203 is clamped into the inner ring of the fixed bearing 206 in the fixing frame, thereby fixing and restricting the shell body 1 to complete the installation and replacement process of the shell body 1.

[0029] Optionally, in order to better observe the rotation of the shell body 2 in the simulation box 1, the simulation box 1 in this embodiment is made of tempered glass.

[0030] See attached Figure 3 The rotation assembly includes a drive rod 301, which is vertically mounted within the simulation box 1. The drive rod 301 passes through a mounting hole provided on the fixed rod 205 in the fixed frame. The bottom of the drive rod 301 is connected to the drive box 3, and is driven to rotate by the drive box 3. A first transmission gear 302 is mounted on the drive rod 301, and a second transmission gear 304 is mounted on the exterior of the shell body 1, meshing with the first transmission gear 302. Drive box 3 drives the drive rod 301 to rotate, and the drive rod 301 drives the shell body 1 to rotate via the first transmission gear 302 and the second transmission gear 304, thereby simulating the shell rotation process.

[0031] In this embodiment, a second driving mechanism is provided in the driving box 3, and the second driving mechanism includes a second motor. A second driving gear is installed on the output shaft of the second motor, and a second driven gear is installed at the lower end of the driving rod 301. The second driving gear and the second driven gear are connected by a chain.

[0032] In the embodiment, a transparent protective cover 4 is installed on the side wall of the simulation box 1 through a hinge. The protective cover 4 is made of tempered glass and is locked to the simulation box 1 through a buckle. Through the setting and use of the protective cover 4, it is convenient to open the simulation box 1 to disassemble and assemble the shell body 1. At the same time, it can reduce dust from entering the interior of the simulation box 1 during the simulated rotation.
