Detailed Implementation

[0022] 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.

[0023] refer to Figure 1-2 As shown, the present invention provides a dry ice deburring device for a mid-frame, comprising: a dry ice cleaning machine 1, a hose 2 and a cleaning tank 3 connected in sequence. A ring mounting frame 5 is provided through the cleaning tank 3. A rotating component is rotatably mounted in the ring mounting frame 5. Multiple clamps 12 for clamping the mid-frame are distributed in a ring array on the rotating component. Based on the rotation, the multiple clamps 12 pass through the extension line of the end of the hose 2 in sequence.

[0024] As described above, using the dry ice cleaning machine 1, hose 2, cleaning tank 3, annular mounting bracket 5, rotating component, and multiple clamps 12 provided by this utility model, multiple middle frames are sequentially placed into the clamps 12 outside the cleaning tank 3. At this time, the rotating component rotates on the annular mounting bracket 5, thereby causing the middle frames on the multiple clamps 12 to pass through one end of the hose 2 in sequence. Dry ice is sprayed onto the middle frames that have passed through through the dry ice cleaning machine 1 and hose 2, thereby removing the burrs on the middle frames. The cleaning tank 3 prevents the dry ice from splashing in all directions.

[0025] Furthermore, to facilitate clamping the middle frame in the clamp 12, refer to Figure 5 and Figure 7 As shown, each clamping seat 12 has a through-hole 13 for accommodating the middle frame. Each clamping seat 12 has a mounting cylinder 15 on both symmetrical sides. Each mounting cylinder 15 contains a clamping block 14 extending through into the clamping hole 13. A spring 6 abuts against the clamping block 14 within the mounting cylinder 15. When the middle frame is placed in the clamping hole 13, the clamping block 14 is pushed into the mounting cylinder 15. The elastic force generated by the compression of the spring 6 acts on the middle frame through the clamping block 14, thereby clamping and installing the middle frame in the clamping hole 13, thus preventing the middle frame from detaching from the clamping hole 13 during dry ice cleaning.

[0026] In this utility model, combined with Figure 1-4 As shown, the outer side of the ring mounting bracket 5 in this embodiment is also provided with a drive mechanism 4 for driving the rotating part to rotate. The drive mechanism 4 includes a motor 8 and a gear 7 installed at the output end of the motor 8. An external gear ring 11 is provided at the top edge of the rotating part, and the gear 7 is meshed with the external gear ring 11.

[0027] As described above, when using the drive mechanism 4 provided by this utility model, the motor 8 in the drive mechanism 4 is started, driving the gear 7 to rotate, thereby driving the external gear ring 11 to rotate, and then driving the rotating part to rotate on the annular mounting frame 5, so that multiple clamps 12 drive multiple middle frames to enter the cleaning tank 3 in sequence.

[0028] In this utility model, combined with Figure 2-3 and Figure 5-6 As shown, the annular mounting bracket 5 of this embodiment includes an inner ring seat 10 and an outer ring seat 9 with different inner diameters arranged sequentially from the inside to the outside. A plurality of connecting rods 17 for connection are provided between the outer ring seat 9 and the inner ring seat 10. Annular grooves 20 for rotating parts are opened on opposite sides of the outer ring seat 9 and the inner ring seat 10. The motor 8 is mounted on the outer ring seat 9.

[0029] As described above, when using the annular mounting bracket 5 provided by this utility model, the outer ring seat 9 and the inner ring seat 10 in the annular mounting bracket 5 provide a rotating mounting position for the rotating component. The outer ring seat 9 and the inner ring seat 10 are installed and fixed by multiple connecting rods 17. When the motor 8 starts, it drives the rotating component to rotate in the annular groove 20 on the outer ring seat 9 and the inner ring seat 10, thereby driving multiple clamps 12 to enter and exit the cleaning tank 3.

[0030] Furthermore, to facilitate the through-mounting of the outer ring seat 9 and the inner ring seat 10 onto the cleaning tank 3, refer to... Figure 2 As shown, the cleaning tank 3 has two through openings 18, and the outer ring seat 9 and the inner ring seat 10 are installed through between the two openings 18. The two openings 18 facilitate the through installation of the outer ring seat 9 and the inner ring seat 10 on the cleaning tank 3, thereby providing a rotational mounting position for the rotating parts inside and outside the cleaning tank 3. When the rotating parts rotate, they drive multiple clamps 12 from the outside of the cleaning tank 3 into its interior.

[0031] In this utility model, combined with Figure 4-5 As shown, the rotating component of this embodiment includes a first moving ring 16 and a second moving ring 19 arranged coaxially from the inside to the outside. Multiple clamps 12 are welded between the first moving ring 16 and the second moving ring 19. The first moving ring 16 and the second moving ring 19 are respectively rotatably installed in two ring grooves 20.

[0032] As described above, the rotating component provided by this utility model consists of a first moving ring 16 and a second moving ring 19. Multiple clamps 12 are installed between the first moving ring 16 and the second moving ring 19, and the multiple clamps 12 are arranged in a ring array in the gap between the first moving ring 16 and the second moving ring 19, thereby providing an installation position for the multiple clamps 12 to rotate on the ring mounting frame 5. The external toothed ring 11 is installed on the second ring seat. When the gear 7 rotates, the external toothed ring 11 can drive the first moving ring 16 and the second moving ring 19 to rotate on the ring mounting frame 5.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
