Wheel fixture

Abstract

The invention discloses a wheel fixture. When the wheel fixture is used, the wheel width is detected in the first place, a servo motor I drives a lead screw to rotate, a supporting block and a lifting plate are automatically adjusted to proper heights through nuts, a mechanical arm places a wheel above an end face block, an air tight device is pressed down, and an oil cylinder pulls a chuck so that a clamping jaw can tighten a wheel central hole in an expanding manner; meanwhile, four air cylinders make a clamping block tightly press the outer side of the wheel, and the wheel is completely positioned; at the moment, a wheel bolt hole can be drilled and machined; after machining is completed, a servo motor II makes a right shaft, a right ear plate and a turning-over part rotate by a certain angle through a speed reducer II; high-pressure oil is introduced into a cavity between a left expansion sleeve and a left end cover II and a cavity between a right expansion sleeve and a right end cover II, and the left expansion sleeve and the right expansion sleeve tightly lock a left shaft and the right shaft respectively. The wheel fixture is applicable to drilling machining of wheels of different outer circle diameters, different central hole diameters and different wheel width sizes and particularly applicable to mixed routing and automated batched machining production.

Description

technical field [0001] The invention relates to a jig, in particular to a jig for drilling a wheel. Background technique [0002] In the machining production process of aluminum alloy wheels, after the outer rim is turned, the bolt holes and valve holes need to be drilled on the machining center. Traditional equipment is affected by parameters such as outer circle diameter, center hole diameter, and wheel width. , During processing, one set of fixtures usually corresponds to one wheel type, which has very poor versatility and is not suitable for mixed-line processing production. Moreover, it is time-consuming and laborious to replace fixtures, which will seriously affect production efficiency. The industry urgently needs a fixture that meets the needs of mainstream wheel processing enterprises, mixed lines and automated mass production and processing. Contents of the invention [0003] The purpose of the present invention is to provide a wheel fixture, which can adapt to ...
