[0018] The technical solutions in the embodiments of this utility model will be clearly and completely described below.
[0019] like Figure 1 and Figure 2 As shown, a rotary clamping structure for a laser detonation machine includes a worktable 1. A rotating seat 2 is disposed below the worktable 1. The rotating seat 2 is fixed to the worktable 1 by screws. A shaft hole is machined in the rotating seat 2, and a rotating shaft 3 is disposed in the shaft hole. The upper end of the rotating shaft 3 passes through the worktable 1 and is connected to a clamping seat 4. A connecting sleeve 5 is machined at the bottom of the clamping seat 4. The connecting sleeve 5 is fitted onto the top of the rotating shaft. A locking screw 6 is connected to the side of the connecting sleeve 5. After the locking screw 6 is tightened, the connecting sleeve 5 and the rotating shaft 3 are locked together.
[0020] The clamp base 4 has multiple clamps on its surface, which are used to clamp glassware. Each clamp includes a sliding bar 7 at the bottom, and a clamping bar 8 is connected to the surface of the sliding bar 7. The clamp base 4 has a connecting groove 9 machined on its surface, and the sliding bar 7 is disposed in the connecting groove 9. The sliding bar 7 and the sliding groove 9 adopt a "T" shaped structure to prevent the clamp from falling off the clamp base 4.
[0021] The lower end of the rotating shaft 3 passes through the rotating seat 2 and is connected to a drive wheel 10. The drive wheel 10 can be a gear, sprocket, or synchronous wheel. The drive wheel 10 is mounted on the rotating shaft 3 via a key block. A locking nut 11 is connected to the tail of the rotating shaft 3. After the locking nut 11 is tightened, it presses the drive wheel 10.
[0022] The bottom of the shaft hole is machined with a bearing hole, and a bearing 12 is installed in the bearing hole. The lower end of the rotating shaft 3 passes through the bearing 12. A shoulder is machined on the rotating shaft 3 to hold the inner ring of the bearing 12. A spacer 13 is provided in the bearing hole. A pressure cap 14 is installed at the opening of the bearing hole. The spacer 13 and the pressure cap 14 press against the outer ring of the bearing 12.
[0023] A piston hole is machined at the upper end of the rotating shaft 3, and a piston rod 15 is installed inside the piston hole. A piston ring 16 is machined on the piston rod 15, and a sealing ring 17 is installed on the side of the piston ring 16. A through air inlet 18 is machined inside the rotating shaft 3. One end of the air inlet 18 is connected to the tail of the piston rod 16, and a rotary joint 19 is installed at the other end of the air inlet 18. The rotary joint 19 prevents the air inlet hose from rotating with it. An air inlet pipe is installed inside the rotary joint 19 and is connected to an external hose. A bearing is installed inside the air inlet pipe and it is sealed by a mechanical seal. After compressed gas is introduced into the air inlet pipe, the piston rod 15 moves.
[0024] The piston rod 15 is positioned at the top of the chuck on the surface of the clamp seat 4. The top of the piston rod 15 is machined with a conical surface 20, and the end of the sliding bar 7 is machined with an inclined surface that mates with the conical surface 20 at the top of the piston rod. When the piston rod rises, it opens the chuck. The end of the connecting groove 9 is machined with a spring hole, and a plug 21 is connected to the end of the spring hole. A sliding bar spring 22 is provided between the plug 21 and the end of the sliding bar 7. A spring positioning post 23 is machined at the end of the sliding bar 7, and one end of the sliding bar spring 22 is sleeved on the spring positioning post 23. After the piston rod 15 retracts, the sliding bar spring 22 pushes the sliding bar 7, causing the clamping bar 8 to clamp the glassware.
[0025] A retaining ring 24 is installed at the opening of the piston hole, and a return spring 25 is provided between the retaining ring 24 and the piston ring 16. After the gas is cut off, the return spring 25 causes the piston rod 15 to return to its original position.
[0026] The piston rod 15 has a spline groove 26 machined on the outer side of its bottom, and a spline groove hole 27 machined on the bottom of the piston hole. The spline groove 26 and the spline groove hole 27 engage and are connected by splines, which drive the piston hole to rotate when the rotating shaft rotates.
[0027] When the blasting machine is working, compressed gas is introduced into the rotating shaft 3 of the rotating clamping structure, causing the piston rod 15 to move upward and open the chuck, placing the glassware onto the surface of the fixture seat 4. After the gas is cut off, the piston rod 15 retracts under the action of the return spring 25, and the chuck clamps the glassware under the action of the sliding bar spring 22. Then, driven by an external motor, the rotating shaft 3 drives the fixture seat 4 to rotate, performing laser cutting blasting.
[0028] This utility model is not limited to the embodiments described. Those skilled in the art can still make some modifications or changes without departing from the spirit and scope of this utility model. Therefore, the scope of protection of this utility model shall be determined by the scope defined in the claims.
