Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Rotatory die head dabber goes up and down acceleration mechanism, including worm-gear case 1, wear to be equipped with worm 2 in the worm-gear case 1, worm case 1 is all extended at the both ends of worm 2, and wherein one end is provided with hand wheel 3. By rotating the hand wheel 3, the worm-worm gear structure can drive the mandrel to lift. The other end of the worm opposite to the hand wheel is provided with an outward extending shaft head 10.

The worm gear case comprises a worm gear case 1 and is characterized in that a speed-up gear case 4 is arranged on one side of the worm gear case 1, a transmission assembly 6 is arranged in the speed-up gear case 4, a driving assembly 7 is connected onto the transmission assembly 6, the driving assembly 7 is connected with an outward extending shaft head 10, and a rocking handle 5 is connected onto the transmission assembly 6. Through rotating rocking handle 5, can conduct power to worm 2 through the linkage of drive assembly 6 and drive assembly 7 to realize the lift to the dabber from another orientation, and the lift regulation speed in this orientation surpasss the lift regulation speed of hand wheel 3 greatly, realizes the acceleration rate effect to the dabber lift.

Specifically, the transmission assembly 6 comprises a transverse shaft 8 arranged in the speed-increasing gear box 4, transmission gears 9 meshed with each other are arranged between the transverse shafts 8, and force is transmitted through the transmission gears. The transverse shaft 8 comprises three input shafts, three intermediate shafts and three output shafts. The input shaft and the output shaft both extend out of the speed-increasing gear box, and the rocking handle is arranged on the output shaft, so that the whole transmission assembly is driven. The transmission gear 9 comprises a large gear arranged in the middle of the input shaft, a large pinion and a small pinion arranged on the intermediate shaft respectively, and a small pinion arranged in the middle of the output shaft, wherein the large gear and the small gear are meshed to realize the transmission effect.

The drive assembly 7 includes a large bevel gear 11 and a small bevel gear 12. A large bevel gear 11 is fixed on the output shaft and a small bevel gear 12 is arranged on the outward extending spindle head 10. The large bevel gear 11 and the small bevel gear 12 are engaged with each other, and the axial directions of the two are arranged at a right angle. The force transmitted by the transmission assembly can be transmitted through the big bevel gear 11 and the small bevel gear 12 in sequence, so that the force is transmitted to the worm 2, and finally, the speed-up effect is achieved on the lifting of the mandrel relative to the hand wheel.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
