Description

Technical Field

[0001] This utility model relates to the field of surface treatment technology, and in particular to a mandrel surface trimming device. Background Technology

[0002] In the casting industry, mandrels are the core component of molds used to cast complex shapes. Mandrel surface finishing devices are used to finish the mandrel surface formed during the casting process, removing surface defects and ensuring the surface smoothness and dimensional accuracy of the mandrel. This is crucial for ensuring the quality of castings, especially for precision castings and high-requirement castings.

[0003] A mandrel surface finishing device includes a long rotating plate, a sliding block, etc. The working principle of the mandrel surface finishing device is to remove surface irregularities or wear layers by precisely controlling the contact method, angle, pressure and movement trajectory between the finishing tool and the mandrel surface during the finishing process, thereby improving the surface quality and precision.

[0004] In existing technologies, some mandrel surface finishing devices use a fixed mandrel for surface treatment. This ensures stable contact between the finishing tool and the mandrel surface. However, during the process, the mandrel experiences uneven wear due to prolonged fixation, affecting the uniformity and accuracy of the finishing effect. Furthermore, the fixed mandrel is usually static, which limits the uniform treatment of different parts of the mandrel surface during the finishing process. The mandrel needs to withstand certain friction and pressure during the finishing process, but improper fixation or lack of dynamic adjustment can lead to uneven stress on the mandrel surface, failing to achieve the desired surface finishing effect. Therefore, a mandrel surface finishing device is proposed to solve the above problems. Utility Model Content

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.

[0032] Reference Figures 1 to 3 The present invention provides an embodiment of a mandrel surface finishing device, comprising a base plate 1, which is the basic support structure of the entire device and plays a role in stability and load bearing. A workbench 2 is fixedly connected to the top of the base plate 1. The workbench 2 provides a stable platform for finishing the surface of the mandrel. A conveying mechanism 3 is fixedly connected to the top of the workbench 2. The conveying mechanism 3 is used to intermittently move the mandrel and provide necessary mobility during the finishing process. A rotating mechanism 17 is fixedly connected to the inner side of the workbench 2. The rotating mechanism 17 drives the mandrel to rotate to ensure uniform surface finishing.

[0033] The conveying mechanism 3 includes a support plate 4, the bottom of which is fixedly connected to the top of the workbench 2. The support plate 4 supports the motor a5 in the drive assembly. A drive assembly, including the motor a5, is fixedly connected to the rear side of the support plate 4. The front side of the motor a5 is fixedly connected to the rear side of the support plate 4. An output shaft a6 is fixedly connected to the output end of the motor a5. The motor a5 outputs power through the output shaft a6 to drive the rotation of the segment rotating plate. A short rotating plate 7 is fixedly connected to the drive assembly. The rear side of the short rotating plate 7 is fixedly connected to the front side of the sliding block 10. The rear side of the short rotating plate 7 is rotatably connected to the front side of the support plate 4. A long rotating plate 8 is rotatably connected to the front side of 7. The short rotating plate transmits the power of motor a5. The rotation of the short rotating plate 7 drives the rotation of the long rotating plate 8. A sliding assembly is fixedly connected to the top of the worktable 2. The sliding assembly slides under the drive of the drive assembly, the short rotating plate 7 and the long rotating plate 8. The sliding assembly includes a top slide rail 9. The bottom of the top slide rail 9 is fixedly connected to the top of the worktable 2. A sliding block 10 is slidably connected inside the top slide rail 9. The sliding block 10 slides inside the top slide rail 9 under the drive of the long rotating plate 8. A pull plate 11 is fixedly connected to the sliding assembly. The bottom of the pull plate 11 is in contact with the top of the pull bar 13.

[0034] The sliding block 10 drives the pull plate 11 to slide back and forth. Driven by the sliding plate, the pull plate 11 slides backward and then locks into the groove at the top of the pull bar 13, pushing the pull bar 13 forward. A limit rod 12 is fixedly connected to the sliding assembly. The limit rod 12 restricts the pull plate 11 from sliding forward, ensuring it is stably locked in the groove of the pull bar 13. A bottom slide rail 14 is fixedly connected to the top of the worktable 2. The pull bar 13 is slidably connected inside the bottom slide rail 14. The pull bar 13... Driven by the movable plate 11, it slides within the bottom slide rail 14. The bottom slide rail 14 provides a fixed sliding path for the pull bar 13. A connecting block 15 is fixedly connected to the outer side of the pull bar 13. The outer side of the connecting block 15 is slidably connected to the inner side of the bottom slide rail 14. A fixed cylinder 16 is fixedly connected to the outer side of the connecting block 15. The bottom of the fixed cylinder 16 is in contact with the top of the worktable 2. The connecting block 15 connects to the fixed cylinder 16. The connecting block 15 transmits the power of the pull bar 13 to drive the fixed cylinder 16 and the internal core rod to move intermittently.

[0035] Reference Figure 1 , Figure 2 and Figure 4The rotating mechanism 17 includes a rotating assembly, which is the driving source of the rotating mechanism 17. The rotating assembly includes a motor b18, which is externally and fixedly connected to the inside of the worktable 2. An output shaft b19 is fixedly connected to the output end of the motor b18. The motor b18 outputs power through the output shaft b19 to drive the rotation of the large pulley 20. The rotating assembly is fixedly connected to the large pulley 20, and a belt body 21 is rotatably connected to the outside of the large pulley 20. The rotation of the large pulley 20 transmits power to the belt body 21. A small pulley 22 is rotatably connected to the inside of the belt body 21. The rotation of the belt body 21 drives the rotation of the small pulley 22. The small pulley 22 is fixedly connected to the rotating shaft a23. The small pulley 22 drives the rotation of the rotating shaft a23. The left side of the rotating shaft a23 and the right side of the rotating shaft b24 are in contact. The top of the worktable 2 is fixedly connected to the rotating shaft b24. The rotation of the rotating shaft a23 drives the rotation of the mandrel, which can ensure that the dressing tool cuts evenly on the surface of the mandrel, thereby avoiding over-cutting in certain areas and ensuring uniform surface quality. The rotating shaft b24 rotates synchronously under the drive of the mandrel, supporting the other side of the mandrel.

[0036] Working principle: When the conveying mechanism 3 is started, the motor a5 of the drive component operates and outputs power through the output shaft a6, driving the short rotating plate 7 to rotate. The short rotating plate 7 then drives the long rotating plate 8 to move. The movement of the long rotating plate 8 acts on the sliding component, causing the sliding block 10 to slide in the top slide rail 9. The sliding block 10 drives the pull plate 11 to slide synchronously. The pull plate 11 slides backward and then forward. When sliding forward, it will be stuck in the groove at the top of the pull bar 13 and stabilized in position under the restriction of the limit rod 12. Then it pushes the pull bar 13 to slide in the bottom slide rail 14. The sliding of the pull bar 13 is transmitted to the fixed cylinder 16 through the connecting block 15, so that the fixed cylinder 16 and the internal core rod can move intermittently. This intermittent conveying, by stopping the core rod each time, allows the dressing tool to cut the core rod only in a fixed position, preventing excessive wear of the core rod.

[0037] Simultaneously, the rotating mechanism 17 starts, the motor b18 of the rotating component operates, and the output shaft b19 drives the large pulley 20 to rotate. The large pulley 20 drives the small pulley 22 to rotate via the belt body 21, and the small pulley 22 in turn drives the rotating shaft a23 to rotate. When the rotating shaft a23 rotates, it drives the mandrel to rotate. The rotating shaft b24 rotates synchronously with the mandrel, ensuring that the mandrel rotates continuously during intermittent movement, thereby achieving uniform finishing of the mandrel surface. Throughout the process, the conveying mechanism 3 is responsible for the intermittent movement of the mandrel, and the rotating mechanism 17 is responsible for the continuous rotation of the mandrel. This ensures that the finishing tool cuts evenly on the mandrel surface, thereby avoiding over-cutting in certain areas and ensuring uniform surface quality.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
