Double-spindle box four-cutter head eight-shaft cylinder boring machine and control method thereof

Abstract

The invention discloses a double-spindle box four-cutter head eight-shaft cylinder boring machine and a control method thereof. The double-spindle box four-cutter head eight-shaft cylinder boring machine comprises a base, an upright post, a spindle box screw rod, a spindle box mounting block, a spindle motor, a motor mounting plate, spindle boxes, rough boring cutters, fine boring cutters, tooling fixture bodies and a workbench. According to the double-spindle box four-cutter head eight-shaft cylinder boring machine, the two spindle boxes are assembled, each spindle box is provided with four cutter shafts, the spindle boxes achieve transmission output through synchronous pulleys, one motor drives the four boring cutter shafts to synchronously move at the same time, and the rough boring cutters and the fine boring cutters move at the same time; the tooling fixture bodies can efficiently and stably fix workpieces in a numerical control hydraulic manner, the clamping force is adjusted during rough and fine boring, and the precision of the processed workpieces is further improved; and the utilization method is simple, the technical requirement on workers is relatively low, the production efficiency of boring can be effectively improved, and a cylinder product with relatively high precision can be obtained.

Description

technical field [0001] The invention relates to a cylinder boring machine, in particular to an eight-axis cylinder boring machine with a double spindle box, four cutterheads and a control method thereof. Background technique [0002] A boring machine is a machine tool that uses a boring tool to bore an existing prefabricated hole in a workpiece. Generally, the rotation of the boring tool is the main motion, and the movement of the boring tool or workpiece is the feed motion. The workpiece does not move during the machining process, let the tool move, align the center of the tool with the center of the hole, and rotate the tool. [0003] It is mainly used to process high-precision holes or complete the finishing of multiple holes at one time. In addition, it can also process other processing surfaces related to hole finishing. The machining accuracy and surface quality of drilling, milling, and cutting are higher than those of drilling machines by using different tools and ...

Problems solved by technology

However, most of the cylinder boring machines on the market currently adopt the structure of the traditional single boring tool, and there is still room for further improvement in terms of production efficiency and convenience.

[0005] As for boring machine fixtures, manual fixtures are common in the market, and the automation level of fixtures is not very high, and there is no hydraulic fixture that can be automatically adjusted for the different clamping forces required for rough and fine boring.
