Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0021] Such as figure 1 As shown, the processing device of the finned hob blade side clearance of the present invention includes a pair of grinding wheels 1 and 2 with the same outer diameter, and a clamping tool for clamping and positioning the blade 5. The pair, namely The two grinding wheels are coaxial and fixedly arranged at the end of the main shaft 3 of the grinding machine with a gap. The adjacent surfaces of the pair of grinding wheels have a guide angle for guiding the blade to enter, and the clamping tool is fixedly arranged on the motor drive head. Frame the end of the mandrel 4. Among them, the opposite surfaces of a pair of grinding wheels have guide angles that guide ...

Abstract

The invention discloses a device for machining a fan hob blade side gap. The device comprises two grinding wheels and a clamping tool used for clamping and positioning a blade, the grinding wheels are coaxial and fixedly arranged at the end of a spindle of a grinding machine at an interval, adjacent faces of the grinding wheels are provided with guide corners guiding the blade to enter, and the clamping tool clamps and fixedly arranges the blade at the end of a mandrel of a motor driving headstock. On the grinding machine with common accuracy, by the grinding wheels in a pair and the clamping tool for clamping the blade, a hub which is provided with the side gap and is micrometer-scale in removal amount, accurate in side and high in surface roughness can be machined by grinding; the device can be used for machining of tool steel and hard alloy hob tooth sides, and machining cost is lowered greatly.

Description

technical field [0001] The invention relates to the technical field of fin hob processing, in particular to a processing device and method for side clearance of a fin hob blade. Background technique [0002] The former of the fin rolling machine is a pair of hobs that are precisely meshed, and the belt material is punched and sheared by the hob to produce several groups of shutters with different window opening directions. Hobs are paired with individual blades one by one, superimposed to form two meshing hobs. At present, most hobs have no gap between the blades and rub against each other during the hobbing process. When the hob works for a long time, due to the friction between the blades and the scouring barrier of the belt material, the tooth side of the hob and the joint of the edge belt are severely worn, which greatly reduces the service life of the hob and even causes it to be scrapped. [0003] Foreign manufacturers of finned hobs should have a reasonable gap betw...
