Description

Technical Field

[0001] This utility model relates to the field of rocker arm processing auxiliary tools, and more specifically to a tooling for forming the tail end of an engine rocker arm with exhaust valve. Background Technology

[0002] Rocker arms are an important component of engines, but there are many types of rocker arms. According to the overall structure, they can be divided into rocker arms with tails and rocker arms without tails. Currently, the tail section of rocker arms with tails is formed by manual bending, which is inefficient. Furthermore, because it is a manual bending process, the force applied during bending cannot be uniform. Although the formed product is qualified, there are certain errors between products, and the uniformity of the products cannot be guaranteed. Utility Model Content

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally 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 to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0017] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0018] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] The terms “first,” “second,” “third,” etc., are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0020] The terms "parallel" and "perpendicular" do not mean that the components must be absolutely parallel or perpendicular, but rather that they can be slightly tilted. For example, "parallel" simply means that its direction is more parallel than "perpendicular," not that the structure must be completely parallel, but that it can be slightly tilted.

[0021] The terms "horizontal," "vertical," and "suspension" do not imply that a component must be absolutely horizontal, vertical, or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply 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 tilted.

[0022] Furthermore, terms like "roughly" and "basically" are used to indicate that the content does not require absolute precision, but rather allows for a certain degree of deviation. For example, "roughly equal" does not simply mean absolute equality; in actual production and operation, achieving absolute "equality" is difficult, and a certain degree of deviation is generally present. Therefore, besides absolute equality, "roughly equal to" also includes the aforementioned situation where a certain degree of deviation exists. Using this as an example, in other cases, unless otherwise specified, terms like "roughly" and "basically" have similar meanings.

[0023] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] See Figure 1 and Figure 2This utility model provides a technical solution: an engine exhaust valve rocker arm tail forming fixture, including a base plate 1, a drive cylinder 2 at one end of the base plate 1, a rack 3 on the piston rod of the drive cylinder 2, a bearing seat 4 in the middle of the base plate 1, a rotating shaft on the bearing seat 4, a gear 5 on the rotating shaft, the gear 5 cooperating with the rack 3, a turntable 6 fixed on the upper end face of the gear 5, a forming shaft 7 on the turntable 6, a forming roller 8 on the forming shaft 7, a positioning block 9 on the upper end face of the rotating shaft, a column 91 for placing the rocker arm 10 on the positioning block 9, and the forming roller 8 for forming the tail of the rocker arm 10. This utility model replaces manual labor with mechanical drive, which not only ensures the same force applied during bending, but also makes the mechanical transmission more stable and reliable, thereby ensuring product uniformity and significantly improving work efficiency.

[0025] Preferably, the base plate 1 is provided with a guide plate, the guide plate is provided with a guide groove, and the rack 3 is provided with a guide ridge that cooperates with the guide groove. This ensures that the movement trajectory of the rack 3 does not deviate and ensures smooth operation.

[0026] Preferably, the forming roller 8 is provided with forming grooves 81, and there are two forming grooves 81, and the distance between the two forming grooves 81 is the same as the distance between the tail of the rocker arm 10.

[0027] Preferably, the base plate 1 is provided with a stop block to limit the stroke and prevent the rack 3 from dislodging.

[0028] The working principle of this utility model is as follows: First, the rocker arm 10 is positioned on the column 91. Then, the drive cylinder 2 drives the rack 3 to move linearly and the gear 5 to move in a circular motion. At the same time, the turntable 6 rotates, and the forming roller 8 contacts the tail of the rocker arm 10 and gradually bends it, thereby completing the forming of the tail of the rocker arm 10.

[0029] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or the technology or knowledge in related fields.
