Description

Tool for machining steering knuckle Technical Field The utility model relates to the technical field of tool clamps, in particular to a tool for machining a steering knuckle. Background The knuckle is a hinge for steering the wheel and is generally fork-shaped. The upper fork and the lower fork are provided with two coaxial holes for installing a main pin, and a main bearing hole on the steering knuckle is used for installing a wheel. The two lugs of the pin hole on the knuckle are connected with the fist-shaped parts at the two ends of the front axle through the main pin, so that the front wheel can deflect around the main pin for a certain angle to steer the automobile. The existing knuckle tool has multiple forms of plane placement, inclined plane placement, back-to-back placement and the like, but the existing knuckle tool is a tool for placing single knuckle for machining, and no multi-station knuckle machining tool capable of meeting requirements of different machining angles at the same time exists at present. Disclosure of utility model The utility model aims to solve the technical problem that the existing steering knuckle machining tool can only machine one workpiece at a time and cannot meet the machining requirements of different angles at the same time. Aiming at the problems in the prior art, the utility model provides a tool for machining a steering knuckle, which can simultaneously machine a plurality of steering knuckles to machine at different angles. The utility model is realized by the following technical scheme: a tooling for knuckle machining comprising: the two ends of the turnover plate are fixed on the processing machine tool through bolts and can be turned over under the driving of turning operation of the machine tool; The main bearing hole machining station is arranged on one side of the turnover plate and comprises a first positioning pin for positioning the knuckle and a first compression cylinder for compressing the knuckle from top to bottom; The inner groove machining station is arranged on one side of the turnover plate and comprises a first positioning column used for positioning a main bearing hole of the knuckle and a second positioning pin used for positioning an ear part of the knuckle; The processing station of the concave inclined surface is arranged on one side of the turnover plate and comprises an inclined bedplate which is fixedly connected with the turnover plate, a second positioning column which is arranged on the inclined bedplate and used for positioning a main bearing hole of the steering knuckle, and a third positioning pin which is used for positioning an ear part of the steering knuckle. In the scheme, the main bearing hole machining station, the inner groove machining station and the inner concave inclined surface machining station are arranged on one turnover plate, so that at least three steering knuckles can be simultaneously fixed for simultaneous machining, and then the steering knuckles can be machined at multiple angles because the turnover plate can be randomly turned under the control of the manipulator. In one possible implementation manner, the main bearing hole machining station is provided with one, three inner groove machining stations are arranged on two sides of the reversible plate, one inner concave inclined surface machining station is provided with one inner concave inclined surface machining station, and the inner concave inclined surface machining station and the main bearing hole machining station are respectively arranged on two sides of the reversible plate. In the scheme, because the processing station of the concave inclined surface only relates to the processing of two small holes on one inclined surface, the processing is faster, the processing station of the main bearing hole also only relates to the processing of one main bearing hole, the processing can be faster, and the processing station of the inner groove relates to the processing of four holes on the inner groove of the knuckle, so that the processing is slow, a plurality of stations can be designed, a plurality of processing stations can be designed at one time, and the processing efficiency is improved. In one possible embodiment, the main bearing bore machining station and the two inner groove machining stations are provided on one side of the tiltable plate, and the inner concave inclined surface machining station and one inner groove machining station are provided on the other side of the tiltable plate. In the scheme, the main bearing hole machining station and the concave inclined plane machining station are large in surface related to one-time machining, so that the main bearing hole machining station and the concave inclined plane machining station are arranged on two sides of the reversible plate respectively, and the inner groove machining station is added to achieve the flattening machining period. In one possible implementation manner, the first positio
