A jig for machining an electric wheel hub

Abstract

The invention discloses an excellent-clamping-function clamp for electric vehicle hub processing. The excellent-clamping-function clamp comprises an operating table. First hydraulic cylinders are connected to the two sides of the top of the operating table through fixing bases, two limiting grooves are formed in the top of the operating table and located between the two first hydraulic cylinders, sliding blocks are connected in the limiting grooves and connected with the first hydraulic cylinders through first hydraulic rods, annular clamping bases are connected to the tops of the sliding blocks through bolts, a circular truncated cone is connected to the top of the operating table and located between the two limiting grooves, a hole groove is formed in the center of the top of the circular truncated cone, and a vertical beam is connected on the operating table and located on the back side of the circular truncated cone. The clamp has the excellent clamping function, and protrusions, caused by shaking, of a hub can be avoided; hub position skewing caused when the hub is separated from the circular truncated cone is avoided, stopping in the processing process is avoided, the working efficiency of processing is improved, time is saved, and it is guaranteed that the hub can not be damaged.

Description

technical field [0001] The invention relates to the technical field of processing electric vehicle accessories, in particular to a jig for processing electric wheel hubs. Background technique [0002] Electric vehicles, that is, electric drive vehicles, have another name called electric drive vehicles. Electric vehicles are divided into AC electric vehicles and DC electric vehicles. Generally speaking, an electric vehicle uses a battery as an energy source, and converts electrical energy into mechanical energy through components such as a controller and a motor to control the current and change the speed of the vehicle. After more than ten years of development, electric vehicles have become the most common means of transportation in the streets and alleys, and are also the most well-known green tools. Moreover, the structure of the electric vehicle is simple, cheap, economical and practical, and the parts on the electric vehicle are also very easy to configure, such as the...

Problems solved by technology

When the electric wheel hub is processed by the existing technology, the clamping of the wheel hub often needs to be completed manually. This processing method has the problems of high labor intensity, inconvenient clamping and low clamping efficiency, which improves the processing of electric vehicles. Therefore, there is an urgent need to improve the clamping technology to reduce costs and improve work efficiency. For example, the patent CN 203304601 U discloses a clamp for processing the front wheel hub of an electric vehicle, and the patent CN203304922 U discloses a clamp for processing the rear hub of an electric vehicle. Fixtures, in the two patents, the front and rear hubs of the electric vehicle are clamped by setting the chuck connecting disc, positioning disc, clamping claw, clamping block and cylinder. These two clamping methods are only through the axis of the hub And clamp the edge of the hub, although the predetermined effect can be achieved, but when the processing is subjected to external force, the hub is easy to arch and break away from the chuck connection plate, so that the position of the hub is shifted, resulting in the stop of processing and reducing the working efficiency of processing , wastes time, and easily damages the hub
