Embodiment Construction

[0014] See Figure 2 to Figure 5 , Diesel engine cylinder head oblique hole processing device of the present invention has a processing table 1 and a rotary indexing plate 5 .

[0015] The processing table 1 includes a base 11 and a rotary support 12 . The base 11 has an oblique rotary support fixing plate 11 - 1 , and the rotary support 12 is fixed on the rotary support fixing plate 11 - 1 of the base 11 . The central mounting part 12-1 of the slewing support 12 is provided with a central hole located in the center and an annular seat cavity for springs with an opening around the central hole facing upward in the axial direction, and a positioning position located outside the annular seat cavity for the springs. The pin hole and the positioning member hole are arranged symmetrically with respect to the axis of the central hole of the slewing support 12 .

[0016] The rotary index plate 5 is provided with a connecting seat portion 51 located in the center, and the connecting...

Abstract

The invention discloses an angular hole drilling device for a cylinder cover of a diesel engine. The device includes a working bench, a control component and a gyration index plate. The working bench includes a pedestal and a gyration support. A central hole, an annular spring support cavity, a knock hole and a location piece hole are formed on the central mounting part of the gyration support. The gyration index plate is provided with a connecting seat part, a bearing used annular seat cavity and an index locating hole. The gyration index plate is provided with a locating angular hole opening upwards; a first corner Alpha is formed between the axis of the locating angular hole and the central axis of the gyration index plate, a second corner Theta is formed between the horizontal plane and the upper end plane of the gyration index plate, and the value of the first corner Alpha is equal to that of the second corner Theta. The angular hole drilling device for the cylinder cover of the diesel engine can drill and form angular holes with higher working accuracy and quality.

Description

technical field [0001] The invention relates to a device for machining oblique holes in a cylinder head of a diesel engine. Background technique [0002] The 16V280ZJB diesel engine is a new type of high-power diesel engine. The cylinder head 8 is one of the main parts of the diesel engine. , an oblique hole 81 with a diameter of d (such as figure 1 As shown), if according to the traditional drilling process, due to the effect of drilling resistance, the drill bit will have a certain displacement and vibration, so the inclination angle of the inclined hole relative to the central axis and its machining accuracy cannot be guaranteed, and the inclined hole after machining There is still some difficulty in the measurement of holes. Contents of the invention [0003] The object of the present invention is to overcome the above problems and provide a diesel engine cylinder head inclined hole machining device capable of ensuring the inclined angle and machining accuracy of the...
