Embodiment 1

[0045] Embodiment 1: The above-mentioned transmission device 300 includes a ring gear 310 connected to the sleeve 110, a sun gear 330 arranged in the middle of the ring gear 310 and connected to the main shaft 200, and a plurality of planetary gears 320 uniformly surrounding the sun gear 330 , the planetary gear 320 is engaged with both the ring gear 310 and the sun gear 330 respectively, and the diameter of the sun gear 330 is equal to that of the planetary gear 320, and the diameters of both are smaller than the diameter of the ring gear 310. Preferably, the planetary gear The number of wheels 320 is 4, but the number of planetary gears 320 is not limited to 4. The planetary gears 320 are evenly arranged around the sun gear 330 and the angle between adjacent planetary gears 320 is 90 degrees. The setting of the wheel 320 ensures the stability of the transmission between the planetary gear 320 and the ring gear 310 and between the planetary gear 320 and the sun gear 330. Compa...

Embodiment 2

[0049] Embodiment 2: The above-mentioned transmission device 300 includes a driving gear 400 connected to the sleeve 110, a driven gear 410 arranged parallel to and coaxial with the driving gear 400, and a plurality of driving gears 400 and 410 arranged between Transmission gear 420, the number of transmission gears 420 is preferably two, but not limited to two, so that the driving gear 400 drives the transmission gear 420 to rotate in the same direction, and makes the driven gear 410 to rotate in the opposite direction, and the main shaft 200 runs through the driving gear in turn 400 and the driven gear 410 protrude outward from the outer surface of the driven gear 410 and a connector 430 is provided at the protruding end, and a plugging block 440 is also provided on the main shaft 200, and the plugging block 440 is arranged on the driving gear 400 Between the driven gear 410 and the driven gear 410, the connecting head 430 can drive the main shaft 200 to slide in the vertical...

Embodiment 3

[0067] Weigh the raw material according to the composition and mass percentage of the above-mentioned sleeve, crush and refine the raw material into metal powder, and roll it into a sleeve blank under a pressure of 450MPa; the sleeve material is mainly composed of the following chemical components in weight percentage: C: 0.35%, Si: 0.40%, Mn: 0.85%, Cr: 1.20%, Ni: 0.20%, Cu: 0.30%, Ti: 0.08%, V: 0.20%, the balance is Fe and other unavoidable impurities ;

[0068] Anneal the above-mentioned sleeve blank at 680°C, and then carry out rough machining, quenching and tempering finishing;

[0069] The processed sleeve blank is subjected to rough grinding, fine grinding, polishing, tumbling, oiling, and etching to remove the oxide layer to obtain a semi-finished sleeve;

[0070] Plating bright chrome on the semi-finished sleeve after the above treatment, the electroplating solution for bright chrome plating contains chromic anhydride 135g / L, sulfuric acid 2.0g / L, and the current den...

Abstract

The invention relates to a high-performance sleeve tool, and belongs to the technical field of fastening tools. The high-performance sleeve tool comprises a body, a main shaft and a sleeve, wherein the main shaft and the sleeve are arranged in the body, the main shaft is connected with the sleeve, and the sleeve is located between the body and the main shaft. One end of the main shaft stretches out of the body and is provided with a tightening and loosening sleeve used for tightening or loosening screws. A transmission device is arranged between the main shaft and the sleeve, and the sleeve rotates circumferentially inside the body and makes the main shaft rotate synchronously along with the sleeve through the transmission device. The sleeve mainly comprises, by weight, 0.25%-0.4% of C, 0.35%-0.45% of Si, 0.7%-0.9% of Mn, 0.8%-1.5% of Cr, 0.1%-0.2% of Ni, 0.1%-0.3% of Cu, 0.05%-0.1% of Ti, 0.1%-0.25% of V, and the balance of Fe and other unavoidable impurities. The sleeve tool is high in tightening and loosening efficiency and use efficiency, wide in application range, high in performance and long in service life.
