Machining equipment for valve seat check spring

Abstract

The invention relates to the technical field of intelligent manufacturing, and discloses machining equipment for a valve seat check spring. The machining equipment comprises a spring machine body, a servo motor is fixedly connected with the left side of an inner cavity of the spring machine body, an unwinding disc is movably connected with the position, located at the top of the servo motor, of the inner cavity of the spring machine body, the middle of the lower surface of the unwinding disc is fixedly connected with the top of an output shaft of the servo motor in a clamped mode, an anti-rustdevice is arranged in the middle of the inner cavity of the spring machine body, and a cleaning device is fixedly connected with the middle of the upper surface of the spring machine body. Accordingto the machining equipment for the valve seat check spring, the normal section of the opening of a guide wheel is in the shape of two symmetrical semicircles with opposite openings, a rust removal block on a driving motor is used for driving an elastic steel wire to slide, meanwhile resilience force provided by an elastic component at the bottom of the guide wheel is used for counteracting the elastic force of the elastic steel wire on the guide wheel, the rebound resilience of the elastic steel wire in the machining process is reduced, and the accuracy of the forming size of the check springis improved.

Description

technical field [0001] The invention relates to the technical field of intelligent manufacturing, in particular to a processing device for a valve seat check spring. Background technique [0002] The valve seat refers to the detachable surface part in the valve, which is used to support the fully closed position of the valve core and form a sealing pair. Generally, the diameter of the valve seat is the maximum flow diameter of the valve. The spring is a mechanical part that uses elasticity to work. In order to control the movement of the parts, ease the impact or vibration, store energy, measure the size of the force, etc., a check spring needs to be used in the valve seat to ensure the normal use of the valve seat; the existing check spring for the valve seat is used. In production, the return spring is generally made of spring steel wire rolled and processed by a spring machine. [0003] When the check spring is processed, it needs to be compressed and formed, then heat t...

Problems solved by technology

[0004] The invention provides a processing device for a check spring of a valve seat, which improves the accuracy of the forming size of the check spring and is convenient for grinding and cleaning the burrs on the surface of the spring, ensures the smoothness of the spring surface, and is beneficial to the production of the finished spring. The advantage of improving the service life of the spring is that it solves the problem that the existing non-return spring processing equipment is not easy to control the resilience of the spring part due to the uneven fit between the inner groove of the curved part and the outer side of the spring, thus causing the spring to break. There is a deviation in size, and the existing non-return spring does not polish and clean the burrs on the surface of the spring. The direct contact between the spring and the external environment is easy to cause oxidation and rust, which is not conducive to the use of the finished spring and affects the service life of the spring.
