Description

Technical Field

[0001] This utility model relates to the field of special-shaped cast iron parts processing technology, specifically a device for processing the bending inner hole of special-shaped cast iron parts. Background Technology

[0002] Irregularly shaped cast iron parts refer to cast iron parts with complex shapes and non-standardized characteristics produced by casting processes. They have high strength, wear resistance and good casting performance, and are widely used in machinery, automobiles, pipelines and other fields.

[0003] Upon investigation, a utility model patent (publication number: CN112872410B) discloses a device for processing the inner hole of a non-circular cast iron part by bending. The device includes a base, a first ring fixedly connected to the upper end of the base, a clamping groove inside the first ring, a clamping plate inside the clamping groove, a movable rod fixedly connected to the middle of the outer side of the clamping plate, a spring-loaded structure inside the first ring, a second ring outside the first ring, a pressing groove inside the second ring, a snap-fit ​​groove at the upper left side of the second ring, a ball bearing at the bottom of the second ring, and a rotating block fixedly connected to the upper end of the second ring.

[0004] In the aforementioned patent, after the irregularly shaped cast iron part is placed inside the clamping groove, rotating the second ring allows the clamping plate to move towards the irregularly shaped cast iron part, thereby achieving clamping and fixing of the irregularly shaped cast iron part. However, in practical applications, there may be a need to flip the irregularly shaped cast iron part. After the device processes the top surface of the irregularly shaped cast iron part, it may be necessary for the operator to remove the irregularly shaped cast iron part from inside the clamping groove, then manually flip it over and put it back into the clamping groove for fixing in order to complete the flipping process of the irregularly shaped cast iron part. The overall operation process is relatively cumbersome and reduces work efficiency.

[0005] Therefore, this utility model provides a device for processing the inner hole of a non-shaped cast iron part by bending, so as to solve the above problems. Utility Model Content

[0016] 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.

[0017] This utility model provides a device for processing the inner hole of a non-standard cast iron part by bending, such as... Figure 1 , Figure 2 and Figure 3 As shown, the system includes a base 1, with a third electric push rod 22 fixedly connected inside the base 1. The third electric push rod 22 is vertically arranged, and its movable end extends to the top of the base 1 and is fixedly connected to a support plate 23. A support column 2 is fixedly connected to the top of the base 1, and a working plate 3 is fixedly connected to the top of the support column 2. A support block 4 is fixedly connected to the top of the working plate 3. A rotating plate 5 is provided on one side of the support block 4, and a rotating shaft 6 is fixedly connected to the side of the rotating plate 5 near the support block 4. A limiting rod 17 is fixedly connected to the side of the rotating plate 5 away from the rotating shaft 6, and a moving plate 9 is slidably connected to the side surface of the limiting rod 17. The rotating shaft 6 passes through the support block 4, and a motor 8 is fixedly connected to the top of the working plate 3. The output end of the motor 8 is fixedly connected to the end of the rotating shaft 6 away from the rotating plate 5.

[0018] The rotating shaft 6 is internally fixedly connected to a first electric push rod 7. The movable end of the first electric push rod 7 passes through the rotating plate 5 and is fixedly connected to the side of the moving plate 9 near the rotating plate 5.

[0019] In actual use, the device requires a drilling device to be installed on the top of the work plate 3. The device has two sets of components, including the rotating plate 5, rotating shaft 6, and support block 4, which are symmetrically installed on the work plate 3. The rotating plate 5 can rotate on the support block 4 via the rotating shaft 6. The work plate 3 is U-shaped, providing space for the rotation of the rotating plate 5. A clamp for holding irregularly shaped cast iron parts is installed on the moving plate 9. When processing irregularly shaped cast iron parts, the parts can be placed on the support plate 23, and then the first electric push rod 7 is activated. The movable plate 9 clamps and fixes the irregular cast iron parts. When the irregular cast iron parts are being flipped, the third electric push rod 22 can be activated to move the support plate 23 downward, providing rotation space for the irregular cast iron parts. Then, the motor 8 is activated. The output end of the motor 8 can drive the rotating plate 5 to rotate 180 degrees through the rotating shaft 6, thereby flipping the irregular cast iron parts. After the irregular cast iron parts are flipped, the third electric push rod 22 can be activated again to move the support plate 23 upward, thereby providing support for the irregular cast iron parts.

[0020] Furthermore, in order to achieve clamping and fixing of irregularly shaped cast iron parts, such as... Figure 3 , Figure 4 and Figure 5 As shown, a mounting plate 10 is fixedly connected to the side of the movable plate 9 away from the rotating plate 5. An electromagnetic plate 11 and a mounting shell 12 are fixedly connected to the side of the mounting plate 10 away from the movable plate 9, respectively. The electromagnetic plate 11 is located inside the mounting shell 12.

[0021] A movable rod 13 is movably connected inside the mounting housing 12. The movable rod 13 is located on the side of the electromagnetic plate 11 away from the mounting plate 10. A connecting cylinder 14 is fixedly connected to the end of the movable rod 13 near the electromagnetic plate 11. A magnetic block 15 is fixedly connected inside the connecting cylinder 14. The end of the movable rod 13 away from the electromagnetic plate 11 extends to the outside of the mounting housing 12 and is fixedly connected to a rubber sleeve 16.

[0022] Before clamping and fixing the irregular cast iron part, the electromagnetic plate 11 needs to be energized. After being energized, the electromagnetic plate 11 and the magnetic block 15 repel each other. When the first electric push rod 7 drives the moving plate 9 to move towards the irregular cast iron part, the moving rod 13 will also move accordingly. There are multiple moving rods 13. When the moving rod 13 comes into contact with the irregular cast iron part, it will automatically retract under the action of the reaction force, thereby realizing the adaptive clamping of the irregular cast iron part. The rubber sleeve 16 increases the friction with the irregular cast iron part and improves the stability of clamping.

[0023] It should be noted that, in order to improve the stability of the converter plate 5, such as... Figure 1 , Figure 2 and Figure 3 As shown, a second electric push rod 18 is fixedly connected to the bottom of the working plate 3, a connecting plate 19 is fixedly connected to the movable end of the second electric push rod 18, a stabilizing plate 20 is fixedly connected to one side of the connecting plate 19, and a limit strip 21 is fixedly connected to the bottom of the stabilizing plate 20.

[0024] The top of the working plate 3 is provided with a sliding groove, the bottom of the stabilizing plate 20 is in contact with the top of the working plate 3, the limiting strip 21 is inserted into the inside of the sliding groove, and the top of the stabilizing plate 20 is in contact with the bottom of the rotating plate 5.

[0025] The movable end of the second electric push rod 18 can drive the stabilizing plate 20 to slide on the working plate 3 through the connecting plate 19. When the stabilizing plate 20 moves, the limiting strip 21 will also slide inside the slide groove. The setting of the limiting strip 21 provides a limiting effect for the stabilizing plate 20, which improves the stability of the stabilizing plate 20 when it moves. The stabilizing plate 20 can be inserted into the bottom of the rotating plate 5 by moving, thereby providing stable support for the rotating plate 5 and reducing the occurrence of shaking or overall tilting of the irregular cast iron parts and the rotating plate 5.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
