Description

Technical Field

[0001] The utility model relates to the technical field of rocker arm processing equipment, and more specifically to a welding device for the tail of an automotive engine valve rocker arm. Background Art

[0002] The engine valve rocker arm device is an important part of the engine. The functions of the engine valve and rocker arm are to cooperate with the camshaft to control the valve opening timing and opening height, and complete the intake and exhaust of the engine. There are also various types of rocker arms used for valves. When producing a rocker arm with a tail, we need to weld the tail of the rocker arm so that the tip of the reserved tail is connected to the rocker arm body. The tail tip and the rocker arm body need to be connected by welding. However, the traditional method can only weld one tail at a time. After welding is completed, the rocker arm is flipped to weld the other tail. The welding efficiency is low, and the welding steps are numerous and the operation is cumbersome, which greatly increases the overall production cycle and production cost.

Detailed Embodiments

[0014] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below 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 shown in the drawings here can be arranged and designed in various different configurations.

[0015] Accordingly, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed present 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.

[0016] 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.

[0017] 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 therefore should not be construed as a limitation to the present invention.

[0018] The terms "first", "second", "third", etc. are only used for distinguishing descriptions and should not be construed as indicating or implying relative importance.

[0019] 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.

[0020] 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.

[0021] In addition, terms such as "substantially", "essentially", etc. 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 merely 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", "essentially", etc. have meanings similar to the above.
