Description

Technical Field

[0001] The utility model relates to the technical field of rocker arm monitoring devices, and more specifically to a detection tool for the outer diameter dimension of the main shaft of an engine valve rocker arm. Background Art

[0002] As an important component in the engine, the rocker arm has relatively high processing precision requirements to reduce the mutual friction between components during operation and improve the service life of the rocker arm. The rocker arm is installed through the main shaft. Therefore, to ensure the normal use of the main shaft, it is necessary to detect whether the outer diameter of the mating end of the main shaft meets the error range after processing to determine whether the product is qualified. However, the current detection methods mostly rely on manual use of vernier calipers. Therefore, when detecting both ends, it is necessary to flip the main shaft and the vernier caliper clamp back and forth, which is time-consuming and laborious, and has low accuracy, greatly increasing the production cycle.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Usually, the components of the embodiments of the present utility model described and illustrated in the drawings here can be arranged and designed in various different configurations.

[0016] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0017] It should be noted that like reference numerals and letters denote like items in the following drawings. Therefore, once an item is defined in one drawing, it does not require further definition and explanation in subsequent drawings.

[0018] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings or the orientation or positional relationship in which the product of the present invention is customarily placed during use. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present invention.

[0019] The terms "first", "second", "third", etc. are only used for descriptive distinction and should not be construed as indicating or implying relative importance.

[0020] The terms "parallel", "perpendicular", etc. do not mean that the components are required to be absolutely parallel or perpendicular, but can be slightly inclined. For example, "parallel" only means that its direction is more parallel relative to "perpendicular", and does not mean that the structure must be completely parallel, but can be slightly inclined.

[0021] The terms "horizontal", "vertical", "hanging", etc. do not mean that the components are required to be absolutely horizontal, vertical or hanging, but can be slightly inclined. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0022] In addition, terms such as "substantially" and "basically" are intended to indicate that the relevant content does not require absolute precision, but can have a certain deviation. For example: "substantially equal" does not only mean absolute equality. Since it is difficult to achieve absolute "equality" during actual production and operation processes, there is generally a certain deviation. Therefore, in addition to absolute equality, "substantially equal" also includes the above-mentioned situation of having a certain deviation. Taking this as an example, in other cases, unless otherwise specified, terms such as "substantially" and "basically" have meanings similar to the above.

[0023] In the description of the present utility model, it should also be noted that unless otherwise clearly specified and defined, the terms "set", "installed", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
