Abstract

The invention discloses a fixture for an inclined oil hole of a cylinder body and relates to the technical field of manufacturing of machining equipment. The fixture comprises a base, an inclined supporting seat is arranged in the front of the base, an inclined plane supporting seat is arranged at the rear of the base, and drill jig supporting seats are both arranged on two side faces of the base between the inclined supporting seat and the inclined plane supporting seat. Drill jig supporting blocks are arranged at upper ends of the drill jig supporting seats, drill jigs are arranged on the drill jig support blocks, and two ends of the drill jigs are connected with the drill jig supporting seats. A transition plate is arranged on the inclined plane supporting seat and is provided with a positioning hole for positioning pins to position a workpiece to be processed, and a center line of the inclined plane supporting seat and vertical center lines of the drill jig supporting seats form an included angle of 41.04 degrees. By the aid of the fixture, problems of large position error and time and energy wasting during model changing production when a drill inclined oil passage hole is processed can be solved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing equipment manufacturing, in particular to a cylinder block inclined oil hole jig for drilling inclined oil passage holes of a crankcase. Background technique [0002] In the past, when the crankcase was processed, two round holes corresponding to the cylinder holes of the first cylinder and the fourth cylinder were provided on the inclined plane support of the cylinder oblique oil hole fixture, such as figure 1 , figure 2 and Figure 5 As shown in Fig. 1, when drilling inclined oil channel holes, the cylinder holes of the first cylinder and the fourth cylinder are used for positioning. This positioning has the following disadvantages: (1) The cylinder holes have not been finished, semi-finished The hole diameter deviation is large, resulting in a large positioning error; (2) When different types of crankcases are produced, due to the different sizes of the cylinder holes, the posi...
