Crankcase vertical-horizontal composite type multi-station combined machine tool

Abstract

The invention discloses a crankcase vertical-horizontal composite type multi-station combined machine tool which comprises a base (10), a hydraulic rotation workbench (11), a rotary table expansion plate (12), a cooling chip removing system (6), a lubricating system (7), a oil press (8) and an electric system (9). The hydraulic rotation workbench (11) and the rotary table expansion plate (12) are mounted on the base (10). The cooling chip removing system (6) is connected with the hydraulic rotation workbench (11). The crankcase vertical-horizontal composite type multi-station combined machine tool has the advantages that the machine tool is reasonable in structural design, simple to operate, high in mechanization degree, high in work efficiency and low in machining cost; the whole combined machine tool adopts the hydraulic rotation workbench with six machining stations which can machine at the same time and load and unload workpieces, the whole machine process only needs clamping and positioning once, machining error caused by inconsistent clamping and positioning can be reduced, and machined products can be accurate in size and good in quality.

Description

technical field [0001] The invention relates to a machine tool, in particular to a combined machine tool with high processing efficiency and high processing accuracy, multiple stations, and capable of simultaneous processing and flow processing. Background technique [0002] The part of the lower part of the cylinder block used to install the crankshaft is called the crankcase. The finishing of the crankcase needs to complete the following processes in sequence, namely: semi-fine boring of the cylinder bore Semi-finish boring crankshaft hole Hole, rough countersink end surface of crankshaft hole; fine milling cylinder surface; finish turning upper support surface; drill 3 holes on upper support surface Chamfering; fine boring cylinder bore Fine boring crankshaft hole Hole, fine spot facing crankshaft hole end face. If ordinary machine tools are used for processing, seven processes are required to complete each process, and each process requires a separate machine to...

AI Technical Summary

Problems solved by technology

Since the cylinder hole and the shaft hole are in a vertical position, two machine tools are required to complete the processing of the same nature of the two holes, unless the processing is completed on a special machine tool or a horizontal machining center; in this case, after processing on one machine tool, The workpiece needs to be disassembled and then transferred to another machine tool for clamping and positioning, resulting in accumulative positioning errors for each clamping and positioning, resulting in reduced machining accuracy of the workpiece, high scrap rate, waste of time, and low production efficiency. The labor intensity of workers is high, and the input cost is high.
