Embodiment Construction
[0058] In order to make the purpose, technical solution and advantages of the present disclosure clearer, the implementation manners of the present disclosure will be further described in detail below in conjunction with the accompanying drawings.
[0059] figure 1 and figure 2 It is a schematic structural diagram of a cylinder body of a double-piston oil cylinder provided by an embodiment of the present disclosure. see figure 1 and figure 2 , the cylinder body of the double-piston oil cylinder includes two cylinders and a flat plate 4 for installation. Each of the two cylinders is a bottom-sealed cylinder, and the inner hole 5 (blind hole, also known as the piston hole) of the cylinder is used to set the piston; the two cylinders are arranged side by side, and the length direction of the two cylinders is the same. The bore openings 5a of the two cylinders are aligned. The installation plate 4 is sandwiched between the two cylinders.
[0060] The two cylinders include ...

The disclosure provides a method for processing a cylinder body of a double-piston oil cylinder, which belongs to the field of mechanical processing. Method: Process the cylinder body blank of the double-piston oil cylinder into a cylinder body. The cylinder body includes two cylinders and a mounting plate. The inner hole of the cylinder is used to set the piston. The two cylinders are arranged side by side. between the cylinders; detect whether the planes where the centerlines of the inner holes of the two cylinders are located are respectively perpendicular to the first datum plane and the second datum plane, the first datum plane is the surface where the mounting plate contacts the outer wall of the first cylinder, The second datum plane is the surface where the mounting plate is in contact with the outer wall of the second cylinder, and the first datum plane is opposite to the second datum plane; When the second datum plane is vertical, process the first datum plane and the second datum plane respectively until the planes where the centerlines of the inner holes of the two cylinders are respectively perpendicular to the first datum plane and the second datum plane.
Description
technical field [0001] The present disclosure relates to the field of mechanical processing, in particular to a method for processing a cylinder body of a double-piston oil cylinder. Background technique [0002] An oil cylinder (also called a hydraulic cylinder) includes a cylinder body and a piston, and the cylinder body is provided with a piston hole for accommodating the piston. When machining the cylinder block, the installation surface of the oil cylinder (located on the outer wall of the cylinder) is generally processed first, and then the piston hole is processed on the cylinder body with the installation surface as the reference plane. [0003] For an oil cylinder with two pistons (hereinafter referred to as a double-piston oil cylinder), the cylinder body includes two piston cylinders, and the two piston cylinders are arranged side by side. The opening direction and length direction of the piston holes of the two piston cylinders are the same. A connecting plate i...
