Abstract

The invention provides a shaft gear quick positioning and clamping device which comprises a base and a mould. The center of the base is provided with a tip, a pressing module is arranged above the mould and comprises a pedestal, the pedestal at least comprises a U-type portion, a rotary shaft penetrates through the U-type portion, the portion, in an inner cavity of the U-type portion, of the rotary shaft is a rectangular spline structure and is sleeved with a cam in a connected mode, the two portions, on the outer side of the U-type portion, of the rotary shaft are a threaded section and a second rectangular spline structure respectively, the threaded section is connected with a stop nut in a matched mode, the second rectangular spline structure is connected with a handle in a matched mode, the cam surface of the cam abuts against a T-type sliding rod, the front end of the rod is provided with an arc-shaped pressing plate, and a reset spring is further disposed between the T-type sliding rod and the bottom of the U-type portion of the pedestal. The shaft gear quick positioning and clamping device has the advantages that quick self-centering of shaft gears is achieved through the tip, manual alignment efficiency is greatly improved, and different tips can be replaced so as to be suitable for the shaft gears with different center holes.

Description

technical field [0001] The invention relates to a positioning and clamping device for gears, in particular to a fast positioning and clamping device and a positioning and clamping method for grinding teeth of long-axis gears. Background technique [0002] When the high-precision shaft gear workpiece is processed by gear tooth forming and grinding, the preset high-precision center hole on the workpiece and the top contact positioning on the machine tool are usually used as the positioning reference of the workpiece. The operator of the forming gear grinding machine must first Use the dial gauge to align the adjustable lower center on the workbench of the gear grinding machine, so that the center of rotation of the lower center of the machine tool and the center of revolution of the machine tool workbench remain within the same accuracy range, and then hoist the workpiece so that the center hole at the lower end is in line with the machine tool The contact positioning of the l...
