Description

Technical Field

[0001] This invention relates to the field of ceramic shaft processing technology, and in particular to a precision ceramic shaft chamfering processing device. Background Technology

[0002] Heavy metal agglomeration may be caused by mining. Ceramic shafts are formed by hydrostatic pressing. Ceramic raw materials have advantages such as high toughness, high bending strength, high wear resistance, good thermal insulation performance, and a thermal expansion coefficient close to that of steel. Therefore, when the shaft clearance is constant, the shaft can work in environments with drastic temperature changes. Ceramics are almost resistant to corrosion, so ceramic shafts are suitable for working in harsh corrosive environments. Ceramic shafts are gradually replacing traditional metal shafts.

[0003] The invention patent with announcement number CN105171553B discloses a ceramic ferrule chamfering processing device, which includes a grinding mechanism, a feeding table, a baffle, a pressure roller, a motor, a feeding pipe, and a V-groove; the device moves along the V-groove to the chamfer to grind the ceramic ferrule, and is very convenient to operate and easy to learn.

[0004] The shortcomings of the existing technology are: it is limited to the grinding of ceramic shafts, and the workpiece is placed by V-groove, pressed by baffle and then ground. Although it is easy to operate and the steps are simple, more time and manpower are used for other steps. The overall mechanism is too limited, making the overall processing too simple, thus slowing down the overall progress. There are many mechanisms that can be added to make the device more complete.

When the two sealing plates 15 are in contact, they completely seal the inside of the cutter disc 16. The two clamping blocks 14 can clamp the shaft core.

[0028] Multiple telescopic electric cylinders 17 are fixedly mounted on the cutter head 16. The telescopic electric cylinders 17 are evenly distributed along the circumference of the cutter head 16. A tool holder 18 is fixedly mounted on the cylinder arm of the telescopic electric cylinder 17. A tool 19 is mounted on the tool holder 18. The tool 19 is replaceable and can be replaced according to different cutting requirements. Multiple support frames 25 are fixedly mounted on the cutter head 16. The support frames 25 are distributed along the circumference of the cutter head 16 and are reinforced with circular frames 26.

The processing is completed by heating by the heating coil 38 and cooling by the cooling coil 39.

[0031] Working principle: The raw material is placed in the feed inlet 3. The feed inlet electric cylinder 4 is activated, which drives the sealing plate 5 to expose the opening on the forming shell 12. The raw material flows into the forming shell 12. After it is full, the feed inlet electric cylinder 4 is activated again, which drives the sealing plate 5 to block the opening. The push motor 7 is activated, which drives the push screw 8 to rotate. The rotation of the push screw 8 drives the threaded plate 6 to move. The threaded plate 6 drives the circular plate 10 through the connecting rod 9 to squeeze the raw material in the forming shell 12 and finally form it. The clamping electric cylinder 13 is activated, which drives the clamping block 14 and the sealing plate 15. The sealing plate 15 opens the opening. The long electric cylinder 11 is fixed on the threaded plate 6. The cylinder arm of the long electric cylinder 11 passes through the circular plate 10 and pushes the shaft away until the shaft is located outside the limit plate 2 35. The limit electric cylinder 2 3 is activated. 4. Limiting electric cylinder 24 drives limiting plate 23 and limiting plate 35 to press and fix the shaft core from the inside. Start drive motor 28, drive motor 28 drives drive gear 29 to rotate, drive gear 29 drives driven gear 30 to rotate, driven gear 30 drives tool holder 31 to rotate, tool holder 31 drives tool disc 16 to rotate through support frame 25, and drives tool 19 and tool 23 to chamfer the shaft core. At the same time, rotary motor 21 can be started to drive the shaft core to rotate for processing. After processing is completed, moving electric cylinder 20 is started, moving electric cylinder 20 drives the shaft core into heating ring 38. Then limiting plate 23 and support frame 25 release the shaft core, and drive roller 37 drives the shaft core to continue moving. After heating and cooling, the processing of the shaft core is completed.
