[0021] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" 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 a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0022] In the embodiments of the present application, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" and "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0023] In machining, we often encounter parts with complex shapes and structures and difficult to process, such as Figure 1 The rocker arm part shown has a complex structure and requires multi-directional drilling during the processing. However, there is currently no positioning piece specifically used for drilling holes in the rocker arm part. During the drilling process, a simple clamp is usually used to clamp and position the part, and then a punch is used to drill holes. This simple clamp cannot stably clamp the rocker arm part and it is prone to tilting during the drilling process. Moreover, when multi-directional drilling is required, it is often necessary to change the position of the rocker arm part to facilitate drilling by the punch. The clamp needs to be adjusted during the adjustment of the position of the rocker arm part. Manpower is required to rotate the corresponding fasteners and calibrate the rocker arm part during the adjustment of the clamp, which makes the replacement of the rocker arm part time-consuming and labor-intensive.

[0024] from Figure 1 , Figure 4It can be seen that the rocker arm part has a cylinder 1, a first connecting plate 2 and a second connecting plate 3, and a special-shaped plate 4 is provided between the first connecting plate 2, the second connecting plate 3 and the cylinder 1. The through hole 40 on the special-shaped plate 4, the groove 20 on the first connecting plate 2, the groove 33 on the second connecting plate 3, the through hole 30 on the second connecting plate 3, and the small hole 10 on the side of the cylinder 1 need to be opened by a punching device later.

[0025] Reference Figures 2 to 4 The present application provides a positioning tool for punching holes in rocker arm parts, including a base 4, a first boss 5 and a second boss 6. The first boss 5 is fixed on the base 4 and is a cylindrical structure. The second boss 6 is fixed on the base 4 and is spaced apart from the first boss 5. A third boss 60 is provided on the second boss 6.

[0026] During use, the barrel 1 of the rocker arm part is sleeved on the cylindrical first boss 5, the through hole 32 on the second connecting plate 3 of the rocker arm part is sleeved on the third boss 60, and the second boss 6 supports the second connecting plate 3 of the rocker arm part, so that the entire rocker arm part can be positioned by the first boss 5, the second boss 6 and the third boss 60, and then the through hole 40 is opened on the special-shaped plate 4 of the rocker arm part, the groove 20 is opened on the first connecting plate 2, and the small hole 10 is opened on the side of the barrel 1 by the punching device. When it is necessary to open the groove 33 on the second connecting plate 3 of the rocker arm part and the through hole 30 on the second connecting plate 3, the rocker arm part is directly turned over, the other end of the barrel 1 is sleeved on the first boss 5, the through hole 21 on the first connecting plate 2 is sleeved on the third boss 60, and then the holes are punched. Therefore, this tooling is very convenient for the replacement of rocker arm parts.

[0027] In some embodiments, the third boss 60 is a cylindrical structure to fit the through hole 21 on the first connecting plate 2 and the through hole 32 on the second connecting plate 3 of the rocker arm part.

[0028] In order to match the protrusion 31 on the second connecting plate 3 of the rocker arm part, in some embodiments, a limiting hole 61 is provided on the third boss 60. When the cylinder 1 is sleeved on the first boss 5 and the through hole 32 on the second connecting plate 3 is sleeved on the third boss 60, the protrusion 31 on the second connecting plate 3 will also be embedded in the limiting hole 61, so the limiting hole 61 provides an escape space for the protrusion 31.

[0029] In some embodiments, the limiting hole 61 is a strip-shaped hole structure, and its shape matches the outer structure of the protrusion 31 .

[0030] In some embodiments, the main body of the second boss 6 is a rectangular structure, and the end of the second boss 6 away from the first boss 5 is a semicircular structure, so that the structure and appearance match the first connecting plate 2 and the second connecting plate 3.

[0031] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the embodiments of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0032] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present application.
