[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4 This utility model provides a technical solution: a worktable with bullseye ball bearings that can slide arbitrarily, including a support mechanism 1, which includes support cylinders 11. An adjustment mechanism 2 is fixedly installed on multiple support cylinders 11. The adjustment mechanism 2 includes a mounting box 21 with a slot at the top. Multiple support cylinders 11 are fixedly installed on the bottom wall of the mounting box 21. A guide rail 211 is fixedly installed on the bottom wall inside the mounting box 21. An adjustment block 23 with a right-angled triangular cross-section is slidably connected to the guide rail 211. A pneumatic push rod 22 is fixedly installed on the outer wall of the mounting box 21. The telescopic end of the pneumatic push rod 22 passes through the outer wall of the mounting box 21 and is fixedly connected to the outer wall of the adjustment block 23. A lifting block 24 with a right-angled triangular cross-section is slidably connected inside the mounting box 21. A sliding block 231 that cooperates with the lifting block 24 is installed on the outer wall of the adjustment block 23. The main body of the worktable 3 is fixedly installed on the top wall of the lifting block 24.

[0017] The pneumatic push rod 22 uses the extension and retraction of its telescopic end to drive the adjusting block 23 to slide on the guide rail 211. When the telescopic end of the pneumatic push rod 22 extends, the adjusting block 23 lifts the lifting block 24 through the sliding block 231, causing the worktable body 3 to rise. When the telescopic end of the pneumatic push rod 22 shortens, the adjusting block 23 moves away from the lifting block 24 through the sliding block 231, causing the worktable body 3 to fall, thereby adjusting the height of the worktable body 3 and making it easier to use the worktable body 3.

[0018] A limit block 241 is provided on the side wall of the lifting block 24, and a limit frame 212 with sliding connection limit block 241 is fixedly installed on the inner wall of the mounting box 21.

[0019] Among them, the limiting block 241 moves longitudinally along the limiting frame 212 to improve the stability of the lifting block 24 when it moves longitudinally.

[0020] Multiple ball bearing assemblies 31 are fixedly installed on the upper surface of the worktable body 3. The multiple ball bearing assemblies 31 are evenly distributed on the upper surface of the worktable body 3. Multiple baffles 32 are fixedly installed on the upper surface of the worktable body 3. The multiple baffles 32 are arranged around the multiple sets of ball bearing assemblies 31.

[0021] Furthermore, the ball bearing assembly 31 converts sliding friction into rolling friction, making it easier to move the product, and multiple baffles 32 prevent the product from slipping off the worktable body 3.

[0022] The ball assembly 31 includes a mounting base 311, which is fixedly mounted on the upper surface of the workbench body 3. A bullseye ball 312 is rotatably mounted inside the mounting base 311. A plurality of support balls 313 are rotatably mounted inside the mounting base 311. The support balls 313 are rotatably connected to the bullseye ball 312. A magnetic coil 315 is provided on the inner wall of the mounting base 311. The magnetic coil 315 is arranged around the bullseye ball 312. An upper end cover 314 is mounted on the mounting base 311.

[0023] Specifically, multiple support balls 313 support the bullseye balls 312, facilitating their rotation. The bullseye balls 312 support the product, making it easier to move. The magnetic coil 315 uses a controller to adjust the current of the magnetic coil 315 via a resistor, thereby adjusting the magnetism of the magnetic coil 315 and attracting the bullseye balls 312. This provides resistance to the bullseye balls 312, preventing lighter products from moving too fast. This method is suitable for products of different weights and models.

[0024] A mounting bracket 111 is fixedly installed on the inner wall of the support cylinder 11. A rotating screw 12 is rotatably installed on the mounting bracket 111. A lifting nut 14 is threaded onto the rotating screw 12. A bevel gear 121 fixedly connected to the rotating screw 12 is rotatably installed on the mounting bracket 111. A bevel gear 131 meshing with the bevel gear 121 is rotatably installed on the inner wall of the support cylinder 11. A drive motor 13 connected to the bevel gear 131 is installed on the outer wall of the support cylinder 11. A support frame 141 penetrating the support cylinder 11 is installed on the outer wall of the lifting nut 14. A universal wheel 15 with a locking plate is fixedly installed at the lower end of the support frame 141. The drive motor 13 can be a self-locking motor to prevent the bevel gear 121 from rotating.

[0025] It should be noted that the casters 15 are used to move the worktable, and the casters 15 are locked with locking plates to prevent movement when the worktable body 3 is in use. The drive motor 13 drives the bevel gear 131 to rotate, thereby driving the rotating screw 12 to rotate through gear transmission, causing the lifting nut 14 to move longitudinally, which in turn drives the support frame 141 to extend or retract, adjust the height of the casters 15, adjust the level of the worktable body 3, and a level can be installed on the worktable body 3 for easy leveling.

[0026] The workflow of this embodiment is as follows: Please refer to... Figure 1-4 A worktable with bullseye ball bearings that can slide arbitrarily is controlled by a programmable controller. All internal motors of the worktable are self-locking motors. The worktable is moved using casters 15, which are locked with locking plates to prevent movement of the worktable body 3 during use. A drive motor 13 rotates a bevel gear 131, which in turn rotates a rotating screw 12, causing the lifting nut 14 to move longitudinally. This, in turn, extends or retracts the support frame 141, adjusting the height of the casters 15 and thus the levelness of the worktable body 3. A pneumatic push rod 22, through its telescopic end, causes an adjusting block 23 to slide on a guide rail 211. When the telescopic end of the pneumatic push rod 22 extends, the adjusting block 23 slides... Block 231 lifts lifting block 24, causing the worktable body 3 to rise. When the telescopic end of pneumatic push rod 22 is shortened, adjusting block 23 moves away from lifting block 24 via sliding block 231, causing the worktable body 3 to fall, thereby adjusting the height of the worktable body 3. Multiple support balls 313 support bullseye balls 312, facilitating the rotation of bullseye balls 312. Multiple bullseye balls 312 support the product, thus facilitating product movement. The magnetic coil 315 uses a resistor to adjust the current of the magnetic coil 315 through the controller, thereby adjusting the magnetic force of the magnetic coil 315, attracting bullseye balls 312, thus providing resistance to the bullseye balls 312, preventing lighter products from moving too fast. It is suitable for products of different weights and models.
