Background

With the development of engine technology, the fuel control system of the engine is developed into an electronic control system from a traditional mechanical control. After the electric control technology is adopted, the inherent characteristics of the engine and the control rule of the engine are not changed, but the information processing amount and the processing function are increased, and the control precision, the frequency response of a control system and the flexibility of control strategies are improved. An electronic control system is adopted, a sensor is needed to collect signals when a timing gear of an engine runs, and a timing signal of a cam shaft gear is one of the signals. The timing gear is used for ensuring the valve timing when the engine runs, so that the opening and closing of the intake valve and the exhaust valve are consistent with the movement of the piston.

If the application number is: in patent cn201521020225.x, a multi-chuck linkage gear clamp is disclosed, comprising a support ring connected to a lathe spindle, wherein the support ring and the lathe spindle are coaxially arranged, a plurality of hinge seats are fixed on the outer surface of the support ring, and the outer ends of the hinge seats are hinged to the middle of a pressure plate. The inner end of the pressure plate is a clamping end of the pressing gear, the outer end of the pressure plate is connected with a rocker, the rocker is connected with the same linkage component, the linkage component is connected with the power end of the rotary oil cylinder, and the support ring and the lathe spindle are provided with a space for the linkage component to reciprocate under the drive of the power end of the rotary oil cylinder. The hinge seat, the pressure plate and the rocker are symmetrically arranged along the axis of the bracket ring. The pressing plates of the clamp not only simultaneously and simultaneously compress or loosen the gear with the same motion trail, but also apply uniform pressure, well realize the synchronization of each pressing plate and improve the positioning precision.

The existing gear clamp is used for fixing the gear, so that the gear is conveniently processed in a signal groove, the outer ring of the gear is easily damaged in the fixing mode, the processed gear teeth are influenced, the use of a follow-up gear is influenced, the yield is reduced, and the practicability is low.

In view of the above, the present invention provides a cam clamp for machining a signal groove of a cam shaft gear, which is improved in view of the conventional structure and defects, so as to achieve a more practical purpose.
