Detailed Implementation

[0014] 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.

[0015] 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.

[0016] 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.

[0017] 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.

[0018] The terms “first,” “second,” “third,” etc., are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0019] 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.

[0020] The terms "horizontal," "vertical," and "sag" do not imply that a component must be absolutely horizontal, vertical, or sagging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," not that the structure must be completely horizontal, but can be slightly tilted.

[0021] 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.

[0022] 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.

[0023] See Figure 1 and Figure 2 This utility model provides a technical solution: a fixing fixture for quickly drilling oil holes at both ends of an engine valve rocker arm, comprising a base plate 1, wherein the base plate 1 has open U-shaped grooves 11 for quick fixing on both opposite sides, a first clamping plate 2 and a second clamping plate 3 on the upper end surface of the base plate 1, forming a rocker arm placement area 4 between the first clamping plate 2 and the second clamping plate 3, and a clamping plate 5 is provided on the side wall of the rocker arm placement area 4 formed by the first clamping plate 2 and the second clamping plate 3, respectively. A first positioning plate 6 and a second positioning plate 7 are respectively provided on the side wall ends of the first clamping plate 2 and the second clamping plate 3 away from the clamping plate 5. The first positioning plate 6 and the second positioning plate 7 are both fixed on the base plate 1. A first cylinder 8 is installed on the first positioning plate 6, and a second cylinder 9 is installed on the second positioning plate 7. The piston rod of the first cylinder 8 is connected to the first clamping plate 2, and the piston rod of the second cylinder 9 is connected to the second clamping plate 3. This invention can complete the drilling of oil holes at both ends of the rocker arm in one go, without repeated disassembly and assembly. It also uses a cylinder for clamping, making the operation simple and labor-saving. Compared with the single-hole processing method, the efficiency is increased by 2-4 times, which can significantly improve the processing efficiency and shorten the production cycle.

[0024] Preferably, the U-shaped grooves 11 on both sides of the base plate 1 are staggered. This makes the positioning more secure and reliable, and reduces the likelihood of misalignment.

[0025] Preferably, both ends of the first positioning plate 6 are provided with first guide holes, and a first guide rod 61 is provided in the first guide hole. One end of the first guide rod 61 passes through the first guide hole, and the other end of the first guide rod 61 is connected to the first clamping plate 2. Both ends of the second positioning plate 7 are provided with second guide holes, and a second guide rod 71 is provided in the second guide hole. One end of the second guide rod 71 passes through the second guide hole, and the other end of the second guide rod 71 is connected to the second clamping plate 3. This ensures that when the cylinder pushes the clamping plate to clamp the rocker arm, it makes a linear motion, so that the rocker arm and the pressure plate 5 fit more tightly, making the fixation more secure.

[0026] Preferably, the base plate 1 has a rocker arm groove located in the rocker arm placement area 4. This makes the placement and positioning of the rocker arm more convenient and quick.

[0027] Preferably, the base plate 1 is provided with a baffle 10, which is attached to one side of the first clamping plate 2 and the second clamping plate 3. This further restricts the placement space of the rocker arm and serves the purpose of positioning the rocker arm, shortening the positioning and clamping time of the rocker arm and further improving work efficiency.

[0028] 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. Modifications and variations made by those skilled in the art that do not depart from the technology and scope of this utility model should be within the protection scope of the appended claims.
