Description

Technical Field

[0001] The utility model relates to the technical field of flywheel casting, in particular to a flywheel sand cleaning device. Background Art

[0002] Flywheels are essential mechanical components used extensively in various powertrain systems. The flywheel casting process includes not only the initial casting process but also sand cleaning, polishing, and heat treatment to enhance performance and service life. After the initial casting process, the flywheel's sides are often covered with a large amount of raw sand, necessitating sand cleaning.

[0003] In the prior art, the common method of sand cleaning is manual knocking or pneumatic hammer vibration. This method quickly shakes the sand core off the flywheel by knocking, but has the disadvantage of low sand cleaning rate, easily leaving a lot of sand that has not been cleaned, and causing great pollution to the surrounding area, causing a large amount of sand in the air, seriously affecting the working environment.

[0010] Furthermore, a detachable sand accumulation groove is provided at the bottom of the dustproof box, and the sand accumulation groove is located below the fixing component and the sand cleaning component.

[0011] The sand collection tank can collect the cleaned sand cores for subsequent processing.

[0012] Furthermore, the bottom of the dustproof box has an inclined surface, and the inclined surface gradually becomes lower from the inner wall of the dustproof box toward the edge of the sand accumulation groove.

[0013] After the fallen sand core falls on the bottom of the dustproof box, it can slide down into the sand accumulation groove.

[0014] Furthermore, the rotating shaft is provided with a plurality of expansion plates capable of moving in the radial direction around the circumference, and the expansion plates can fit with the inner ring of the flywheel.

[0017] By rotating the screw rod 2 to make it move axially in the rotating shaft, the cone block can push the plug rod to move in the socket until the expansion piece fits with the inner ring of the flywheel, thereby fixing the flywheel on the rotating shaft.

[0018] Furthermore, the rotating shaft is detachably connected to a fixed shaft, and the fixed shaft is connected to a driving source.

[0019] After the rotating shaft is removed from the fixed shaft, different rotating shafts can be replaced to suit flywheels of different specifications. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following embodiments of the technical solution of the present invention are described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0031] See also Figures 1 to 4 The utility model provides a flywheel sand cleaning device, including a dustproof box 10, a fixing component 20 and a sand cleaning component 30. After the flywheel 1 is fixed by the fixing component 20, the flywheel 1 is cleaned and scraped by the sand cleaning component 30.

[0032] Specifically, if Figure 1 and Figure 2 As shown, the fixing assembly 20 includes a rotating shaft 21, which is rotatably disposed in the dustproof box 10 and is connected to a driving source. The flywheel can be fixedly sleeved on the rotating shaft 21. The sand cleaning assembly 30 includes a fixing seat 31, a screw 32, a slide rod 33 and a sand cleaning sheet 34. The fixing seat 31 is fixedly disposed in the dustproof box 10, and has two opposite sides respectively provided with a threaded hole 311 and a through hole 312 that are interconnected. The screw 32 is threadedly connected to the threaded hole 311. One end of the slide rod 33 is slidably inserted into the through hole 312. The end of the screw 32 can abut against the slide rod 33. The sand cleaning sheet 34 is disposed on the other end of the slide rod 33 and can abut against the flywheel.

[0033] The flywheel is fixedly mounted on the rotating shaft 21, and the screw 32 is rotated to move it axially within the threaded hole 311, pushing the slide bar 33 and the sand cleaning sheet 34 to move, so that the sand cleaning sheet 34 abuts the flywheel. The drive source is then activated to drive the rotating shaft 21 and flywheel to rotate, and the sand cleaning sheet 34 scrapes the sand cores off the flywheel, greatly improving the coverage rate and cleaning effect. The dustproof box 10 also prevents the sand cores from being scattered.

[0034] Furthermore, a removable sand collection trough 11 is provided at the bottom of the dustproof box 10. The sand collection trough 11 is located below the fixing assembly 20 and the sand cleaning assembly 30. The bottom of the dustproof box 10 has an inclined surface 12 that gradually decreases from the inner wall of the dustproof box toward the edge of the sand collection trough. After falling sand cores land on the bottom of the dustproof box, they can slide down into the sand collection trough 11, where they are collected for subsequent processing.

[0035] Specifically, if Figure 3 and Figure 4 As shown, the rotating shaft 21 is circumferentially provided with a plurality of radially movable expansion plates 23. The rotating shaft 21 is circumferentially provided with a plurality of radially arranged insertion holes 211. The expansion plates 23 are provided with insertion rods 231 that are slidably connected to the insertion holes 211. The rotating shaft 21 is axially provided with a second threaded hole 212, which is threadedly connected to a second screw rod 24. The end of the second screw rod 24 is provided with a tapered block 241, and the end of the insertion rod 231 can be in contact with the tapered block 241. By rotating the second screw rod 24 to move it axially within the rotating shaft, the tapered block 241 can push the insertion rod 231 to move within the insertion hole 211 until the expansion plates 23 are in contact with the inner ring of the flywheel 1, thereby supporting the flywheel from multiple directions to achieve a fixed effect.

[0036] In this embodiment, the rotating shaft 21 is detachably connected to a fixed shaft 25, which is connected to a drive source, which is a motor 22. After the rotating shaft 21 is removed from the fixed shaft 25, a different rotating shaft 21 can be replaced to accommodate flywheels of different specifications. The position of the sliding rod 33 and the sand cleaning blade 34 can be adjusted by the screw 32, also allowing for the adaptation of flywheels of different specifications.

[0037] In addition, a sand cleaning assembly 30 may also be provided on the front or back of the flywheel. This embodiment only shows a schematic diagram of sand cleaning the outer circumference of the flywheel.

[0038] The flywheel sand cleaning device described above operates as follows: flywheel 1 is mounted on rotating shaft 21. Screw 24 is rotated to push rod 231 and expansion plate 23 via cone 241, thereby tightening and securing flywheel 1. Screw 32 is then rotated to move slide 33 and sand cleaning plate 34, bringing the plate 34 into contact with the flywheel. This activates motor 22, driving fixed shaft 25 and rotating shaft 21 to rotate the flywheel. The sand cleaning plate 34 scrapes the sand cores off the flywheel, preventing the dust box 10 from dispersing them.

[0039] The use of the above-mentioned flywheel sand cleaning device can greatly improve the sand cleaning coverage and cleaning effect compared to the traditional knocking method, and can be applied to flywheel sand cleaning of various specifications. In addition, the dustproof box can also prevent the sand core from flying around, thereby improving the surrounding working environment.
