Description

Technical Field

[0001] This utility model relates to the field of PEEK machining, and in particular to a PEEK gear precision hobbing device. Background Technology

[0002] PEEK is a high-performance thermoplastic with excellent mechanical properties, high temperature resistance, chemical stability, and wear resistance. It is widely used in aerospace, automotive, electronics, electrical, and medical fields. PEEK is processed using methods such as injection molding, extrusion, and CNC machining. Its high melting point requires special equipment and technology for processing, and the process is quite difficult. Common processing methods include milling, turning, and laser cutting. These methods can precisely control the size and shape of PEEK. During processing, special attention must be paid to maintaining the stability of the material to avoid thermal degradation and deformation.

[0003] A gear hob is a cutting tool used for machining gears. It is widely used in the production of internal and external gears, worm gears, gear pumps, etc. Shaped like a hob, it is manufactured using high-precision grinding processes and made of high-strength alloy steel or cemented carbide. The gear hob cuts along the tooth profile by contacting the workpiece and rotating, achieving precise tooth surface machining. It is suitable for mass production, offering high machining efficiency and a long service life. Precise control of cutting parameters is necessary during gear hob machining to ensure the quality and accuracy of the gear machining.

[0004] When machining PEEK into gears, a hob is continuously rotated on the PEEK to cut it into the required gear. However, a large amount of debris is generated during the machining process, which accumulates directly on the worktable, affecting the appearance. It can only be manually cleaned after the workpiece is finished, which is time-consuming, labor-intensive, and inefficient. To address this issue, a PEEK gear precision hob rolling device is proposed. Utility Model Content

The support platform 14 simultaneously limits the movement direction of the slide rod 19 and the clamp 21.

[0037] Working Principle: When using this device to produce PEEK gears, the workpiece 22 is first fixed on the support table 14. When the workpiece 22 is placed between the three clamps 21, a hex wrench is inserted into the worm gear 15 and rotated. The worm gear 15 drives the worm wheel 17 to rotate, causing the rotating rod 16 to drive the turntable 18 to rotate. The limiting rod 20's sliding slide rod 19 causes the clamps 21 to slide on the support table 14, clamping the workpiece 22 within the support table 14. The self-locking characteristic between the worm wheel 17 and the worm gear 15 keeps the workpiece 22 stable. Next, the top stabilizing device is pressed onto the axis of the workpiece 22. Then, the cutter 2 and the fan 6 are controlled to work. The cutter 2 begins to rotate and approach the workpiece 22, causing it to begin cutting the workpiece 22, creating the teeth. Once production is complete, simply reverse the worm gear 15 to open the clamps 21. Simply turn it on. The debris generated during the cutting process will be sucked away by the air intake 3 and fall into the collection frame 7 through the pipe 4. The debris will be collected in the collection frame 7 to prevent it from accumulating on the workbench 1 and affecting the appearance and making it messy. After production is completed, the debris in the collection frame 7 needs to be disposed of in time. By pulling the insertion rod 9, the sliding plate 10 will compress the spring 11, so that the insertion rod 9 is retracted into the outer shell 8 and disengaged from the collection frame 7. At the same time, the baffle 12 will automatically fall into the outer shell 8 to block the outlet of the insertion rod 9. Then, the collection frame 7 is pulled out from the sleeve 5 and the debris inside is disposed of. Then it is reinserted into the sleeve 5. Then, under the limit of the limiting plate 13, the baffle 12 is pulled. At this time, the spring 11 will immediately push the sliding plate 10 to reset, and drive the insertion rod 9 to insert into the collection frame 7, so that the collection frame 7 is fixed, thereby making it easy to clean.
