Description

Technical Field

[0001] The utility model belongs to the technical field of cylinder end cover processing, and in particular relates to a tool for processing a 45-degree inclined hole of a cylinder end cover. Background Art

[0002] The cylinder head is an important part of the engine. It is mainly used to seal the cylinder, form a combustion space together with the piston, and withstand the effects of high-temperature and high-pressure gas. During operation, the cylinder head not only bears the mechanical load caused by the gas force and the tightening of the cylinder bolts, but also bears extremely high thermal loads due to contact with high-temperature gas. Therefore, the design and manufacturing requirements of the cylinder head are extremely high, and it must ensure that it has sufficient strength and rigidity, and that the working deformation is small to maintain good sealing.

[0003] In the manufacturing process of cylinder end covers, the processing of inclined holes is a critical and complex process. The existence of inclined holes has an important impact on the working performance of the cylinder end cover, such as the circulation of coolant or lubricating oil to ensure the normal operation of the engine. However, due to the irregular shape of the cylinder end cover workpiece, it is difficult for traditional drilling machines or machining centers to effectively fix it, which brings great difficulties to the processing of inclined holes. Traditional inclined hole processing methods often rely on the skills and experience of operators, and processing accuracy and efficiency are difficult to guarantee. Therefore, it is necessary to design a tooling for processing 45° inclined holes in cylinder end covers. Utility Model Content

[0004] Therefore, the utility model aims to solve the problem in the prior art that it is difficult for a traditional drilling machine or machining center to effectively fix the cylinder end cover, thus affecting the machining accuracy and efficiency.

[0005] To this end, the technical solution adopted is that the utility model is a tooling for processing a 45° inclined hole in a cylinder end cover, comprising: a ground support, a vertical support, a base, an inclined plate and a positioning column. The ground support is arranged in a horizontal direction, and the right end of the ground support is clamped in the lower end of the vertical support. One end of the inclined plate is fitted with the upper end of the vertical support, and the other end of the inclined plate is fitted with the right end of the base. The left end of the ground support passes through the inclined plate and is clamped in the base at one end away from the vertical support. Two positioning columns are arranged at intervals along the length direction of the inclined plate, and bolt holes are respectively arranged on both sides of the positioning columns.

[0006] Preferably, the angle between the inclined plate and the ground support is 45°.

[0007] Preferably, the ground support is connected to the base via a first hexagon socket head screw.

[0008] Preferably, the ground support and the vertical support are connected by a second hexagon socket head screw.

[0009] Preferably, the inclined plate is connected to the upper end of the vertical support by a third hexagon socket head screw.

[0010] Preferably, a foot is provided at the right end of the ground support, and the foot is connected to the vertical support by a fourth hexagon socket head screw.

[0011] Preferably, the base and the inclined plate are connected via a fifth hexagon socket head screw.

[0012] Preferably, two first mounting holes are spaced apart on the base.

[0013] Preferably, two second mounting holes are arranged at intervals on the ground foot.

[0014] The technical solution of the utility model has the following advantages: since the ground support is parallel to the end face of the workbench, the angle between the inclined plate and the ground support is 45°, when the drill bit of the drilling machine drills downward along the vertical direction, a 45° inclined hole can be processed on the cylinder end cover. After processing, the cylinder end cover is removed and the next cylinder end cover is installed, which improves the processing efficiency of the 45° inclined hole, does not need to be disassembled, maintains the consistency of processing, and improves the processing accuracy of the inclined hole.
