Double-end drilling and milling fixture for machining end surface of disk hub

Abstract

The invention discloses a double-end drilling and milling fixture for machining an end surface of a disk hub. The double-end drilling and milling fixture for machining the end surface of the disk hubcomprises a base; a lifting mechanism is fixedly arranged at the upper end of the base; the lifting mechanism comprises a first hand wheel, first gears, rack plates, fixing frames and lifting platforms; the plurality of fixing frames are arranged at the upper end of the base; a plurality of first gears are movably mounted at the middle parts of the plurality of fixing frames through bearings; theplurality of first gears are connected with each other through rotating shafts; the first hand wheel is fixedly mounted on one side, close to the rotating shaft, outside the fixing frame; the plurality of rack plates are movably mounted on one sides, close to the first gears, in the plurality of fixing frames; the plurality of rack plates are engaged with the first gears; lifting platforms are fixedly arranged at the upper ends of the plurality of rack plates; and clamping mechanisms are fixedly arranged at the upper end of the lifting platforms. According to the double-end drilling and milling fixture for machining the end surface of the disk hub, the accurate positioning of the end surface of the disk hub can be limited, and double-end rapid machining can be realized.

Description

technical field [0001] The invention relates to the technical field of disk hub end surface processing, in particular to a double-headed drilling and milling fixture for disk hub end surface processing. Background technique [0002] The disc hub plays an important role in the production of automobile clutches, and the function of the disc hub is to transmit the torque of the driven disc assembly. In the driven disc assembly, the torque without friction plate is transmitted to the disc hub through the spring, and the disc hub is transmitted to the gearbox to ensure the smooth transmission of torque, so the processing of the end surface of the disc hub is particularly important. [0003] The following problems are presented: (1) The size of the drilled hole is unstable. According to the size of the screw hole required by the hub, it is necessary to change the tool; (2) The iron filings and cutting fluid after milling are easy to splash and cause pollution. , Increase the labo...

Problems solved by technology

[0003] The following problems are presented: (1) The size of the drilled hole is unstable. According to the size of the screw hole required by the hub, it is necessary to change the tool; (2) The iron filings and cutting fluid after milling are easy to splash and cause pollution. , to increase the labor intensity of the staff; (3) only one mounting screw hole at each end can be processed at a time, and the second processing needs to be repeated, and the work efficiency is low
