In the Gear Processing production process, inside spline wheel gear blank finish turning is the necessary link in high accuracy inside spline wheel gear manufacturing procedure, because inside spline wheel gear blank finish turning special fixture low precision, end face and cylindrical are beated greatly, affect assembling, running and the service life of inside spline wheel gear product in this type gear process.The inside spline wheel gear blank lathe finish fixture that Gear Processing enterprise is used at present generally adopts elasticity spline mandrel and spline tapering mandrel (1:400), the former convenient mounting and clamping, efficiency is high, but low precision, end face and cylindrical are beated greatly, and the gear blank end face run-out that car goes out maintains 0.It is difficult that 01mm has belonged to; Latter's clamping inconvenience, efficiency is low, each inside spline wheel gear blank clamping needs to take off spline tapering mandrel, knocking inside spline wheel gear blank or spline tapering mandrel with copper rod or nylon hammer makes the two separately or is locked, labour intensity is large, spline tapering mandrel frequently causes well damage to need to change owing to knocking up and down, and the gear blank end face run-out after processing maintains 0.01mm is very normal, and processing cost is high.
Summary of the invention
The technological deficiency existed for existing inside spline wheel gear blank finish turning special equipment, the technology of the present invention, can replace existing gear blank finish turning special fixture, be a kind ofly have that clamping is easy to operate, efficiency is high, inside spline wheel gear blank finish turning built-up jig that the gear blank end face of processing and cylindrical are beated little, that precision is high.
The present invention is achieved through the following technical solutions:
A kind of inside spline wheel gear blank finish turning built-up jig, its structure comprises that the inside spline wheel gear blank clamps accessory and the inside spline wheel gear blank unclamps accessory two parts; Described inside spline wheel gear blank clamps accessory and is arranged on lathe tail, comprises push pedal gyroaxis, push pedal, push pedal boosting-rod; Described push pedal gyroaxis is fixed on the lathe saddle; The other end of the described push pedal of a jag is arranged on described push pedal gyroaxis; Described push pedal boosting-rod is fixed in described push pedal.Described inside spline wheel gear blank unclamps accessory and is arranged on the lathe front portion, comprises hydraulic cylinder, push rod, fore-set, chuck body, internal spline adjustment pad, spline tapering mandrel; Described hydraulic cylinder can promote described push rod horizontal direction and move; The rounded nose trisection posistion of described push rod has described fore-set; Described fore-set can be by the through hole of relevant position on described chuck body; Described spline tapering mandrel is fixed on described chuck body; Described internal spline is adjusted pad and is enclosed within on described spline tapering mandrel.During operation, the described spline tapering mandrel be fixed on described chuck body is good, the inside spline wheel gear blank is contained on described spline tapering mandrel, pull described push pedal that described push pedal boosting-rod drives a jag left horizontal direction move, jaw in described push pedal props up inside spline wheel gear blank right side, makes one tight with being moved to the left with described spline taper core axle sleeve; Described adjustment pad thickness can the adjusting elasticity degree; After gear blank clamps, start the finish turning processing that lathe completes end face and cylindrical.Completion of processing, start gauge tap make the described push rod of described Hydraulic Cylinder to the right horizontal direction move; The described fore-set promoted in described chuck body three through holes moves to right simultaneously; Described fore-set promotes described internal spline and adjusts pad upper right the moving of described spline tapering mandrel, makes the inside spline wheel gear blank move to right to unclamp and takes off.Aforesaid operations is an inside spline wheel gear blank process, changes gear to be processed, repeats above operation sequence.
Beneficial effect of the present invention is:
A kind of inside spline wheel gear blank finish turning built-up jig, its structure comprises that the inside spline wheel gear blank clamps accessory and the inside spline wheel gear blank unclamps accessory two parts; Described inside spline wheel gear blank clamps accessory and is arranged on lathe tail, comprises push pedal gyroaxis, push pedal, push pedal boosting-rod; Described inside spline wheel gear blank unclamps accessory and is arranged on the lathe front portion, comprises hydraulic cylinder, push rod, fore-set, chuck body, internal spline adjustment pad, spline tapering mandrel.The present invention has advantage: 1.Efficiency is high, and clamping is easy to operate, and labour intensity is low.2。Precision is high, and the gear blank end face of processing and cylindrical are beated and be less than 0.006mm, steady quality.3。The product processing cost is low.
