The invention relates to an automatic turnover device for milling of the top surface of a V-shaped engine cylinder block, and belongs to the field of mechanical manufacturing. The automatic turnover device comprises a cylinder block locating and clamping unit, a turnover device and a clamp body, wherein the cylinder block locating and clamping unit is fixed on a turnover table; the turnover device drives the turnover table to turn over leftwards and rightwards by 30 degrees and enables the turnover table to be stably retained at a horizontal position; and the turnover device is fixedly mounted on the clamp body. The automatic turnover device has the advantages of compact and stable overall structure, safety and reliability in use and high rigidity, and the problem of shaking in a machining process can be avoided. By the adoption of a pneumatic clamping mode, the clamping efficiency is improved. By one-time clamping, the machining efficiency and the machining precision of milling of the top surface of the V-shaped engine cylinder block are improved; and the production efficiency is improved, and the labor cost is reduced.
Description
technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to a tool for milling the top surface of a V-shaped engine cylinder block, especially an automatic turning device for milling the top surface of a V-shaped engine cylinder block. Background technique [0002] The included angle between the normals of the two planes on the top surface of the V-shaped engine block is 60°, and the plane on the top surface must be in a horizontal position during milling, which requires that the fixture can be turned left and right by 30°. In the prior art, the tooling fixture for milling the top surface of the in-line engine cylinder block is relatively common, and there is also a device for milling the V-type engine cylinder block, but both of them require two clamping, the positioning error is large, time-consuming and laborious, and affect the processing efficiency, so it is not suitable The needs of modern production. Needs to be improved. ...
