Description

Technical Field

[0001] The utility model relates to the technical field of straightening equipment, in particular to a valve stem straightening equipment. Background Art

[0002] The valve is an important component of the engine. The function of the valve is to input air into the engine and discharge the exhaust gas after combustion. The verticality of the disc and the stem and the straightness of the stem have an important impact on the normal operation of the valve in the engine. At present, the verticality between the stem and the disc of the valve is basically adjusted manually, which not only fails to accurately adjust the valve, but also increases the labor force. Therefore, automatic and accurate straightening of the valve can ensure the improvement of valve processing efficiency.

[0003] The application number is CN202222394443.6, which discloses a valve straightening device, including: a straightening device for keeping the axis between the stem of the valve and its disc in a horizontal state, a heating furnace, a conveying platform, a mechanical arm, and an output end having a three-jaw chuck for clamping the valve disc. The straightening device includes: a rolling mechanism and a placement detection mechanism. The rolling mechanism is used to straighten the stem of the valve in a rolling manner. The rolling mechanism includes a support platform and a disc support block arranged on the top of the support platform, a rod support member and a rod rolling member arranged above the support platform. The placement detection mechanism is arranged on the side of the support platform away from the mechanical arm. The utility model solves the problem that the current valve straightening is not only inaccurate but also inefficient through manual operation, avoids the situation where the valve stem cannot be straightened due to inaccurate placement, and improves the accuracy and efficiency of valve straightening.

[0004] A valve straightening device disclosed in the above document has the following defects: in the process of straightening the valve stem by the device, when the rod body is rolled and squeezed by the rolling part, the rolling part can easily squeeze the surface of the rod body to wear, and debris will fall from the rod body. The debris is easily hidden in the rolling part. At this time, a corresponding structure is required to clean the debris inside the rolling part and on the rod body, otherwise the debris will make the inner wall of the rolling part irregular, and finally cause the surface of the rod body to be worn to an uneven surface when it is rolled and squeezed by the rolling part, thereby reducing the overall quality of the valve stem body.

[0005] It can be seen from this that the existing valve straightening equipment does not have the function of effectively cleaning the debris dropped from the rod body during processing. It is necessary to improve the existing deficiencies and provide a function that can effectively clean the debris dropped from the rod body during processing. Utility Model Content
