Embodiment Construction

[0025] As shown in Figure 1, a gear precision hot rolling mill is composed of a first hobbing die transmission mechanism 1, a second hobbing die transmission mechanism 5, a workpiece loading and unloading compacting mechanism 6, a lifting mechanism 4, and a first screw rod The propulsion mechanism 7, the second screw mandrel propulsion mechanism 14, the oil tank 13, the temperature control device and the frame 2 are composed. The frame straddles the both sides of the oil tank, and the slide block 42 in the lifting mechanism is installed on the slide block rails provided on both sides of the frame, and is connected with the piston rod of the hydraulic cylinder 41 fixed on the frame. The first hobbing mold transmission mechanism, the workpiece loading and unloading compacting mechanism and the second hobbing mold transmission mechanism are vertically suspended from left to right on the slide block.

[0026] The first hobbing mold transmission mechanism 1 is composed of a servo m...

Abstract

A pinion precision hot rolled squeezing and milling device and a method for processing belong to the field of precision-machined machinery devices and craft technology. The purpose of the invention is to provide the pinion precision hot rolled squeezing and milling device, and the method for processing which are economical, practical and have low inaccuracy and high accuracy and are applicable to be in mass production. The technical points are that a framework is straddled and arranged on the two lateral sides of an oil tank, and a slider controlled by a hydraulic oil tank is arranged on the framework, wherein a first gear hobbing die actuating mechanism, a work-piece handing hold-down mechanism, and a second gear hobbing die actuating mechanism are hung vertically and consecutively from left to right, the two lateral sides of the lower portion are correspondingly arranged with pushing shelves of a first screw mandrel pushing mechanism and a second screw mandrel pushing mechanism which are respectively connected with an upper bearing block and a lower bearing block of the first gear hobbing die actuating mechanism and the second gear hobbing die actuating mechanism. Compared with prior crafts and devices, the invention is a finishing tooth processing device and craft which is more advanced, reasonable and scientific, economical, practical, lowly inaccurate, and further has the advantages of high efficiency and high accuracy, and is adaptable for mass production without cutting.

Description

technical field [0001] The invention relates to a gear precision hot rolling mill and a processing method thereof. Background technique [0002] Gear is an important power transmission part in mechanical equipment, and its application is extremely extensive. In the traditional gear processing in China, the rolling (plugging) gear-shaving-heat treatment-finishing process is widely used. To obtain high-precision hard-toothed gears, the methods of finishing are usually used: honing, grinding, fine shaving of hard-toothed surfaces, and hobbing of hard-toothed gears. [0003] Although gear honing has high efficiency, good surface quality, and no burns, it can eliminate the roughness of the hard tooth surface of the gear after rolling and insertion, and the burrs and scratches on the tooth surface caused by slight bumps, and can also correct the tooth surface to a certain extent. However, since the accuracy of the honing wheel is the key to improving the accuracy of the honing w...
