Problems solved by technology

[0004] However, processing the inner cavity of the part, such as machining the hole for storing lubricant in the inner cavity of the oil-free bearing, etc., this kind of processing is still relatively cumbersome and the production efficiency is not high.
Generally, existing devices and methods can only process one hole at a time inside this type of part, and this type of part cannot be processed by a multi-hole drilling machine, so the processing efficiency is low

Abstract

The invention discloses an inner cavity drilled multi-cutter machining device. The device comprises a cutter mechanism, a transmission driving mechanism and a feeding mechanism mounted in a box, and a support mechanism connected between the outer wall of the box and a workpiece in a supporting manner, wherein the transmission driving mechanism is connected with the cutter mechanism to drive the cutters to rotate; the feeding mechanism is connected with the cutter mechanism, and controls the radial movement of the cutter mechanism; the cutter mechanism comprises multiple sets of cutter components uniformly distributed in the periphery; and each set of cutter components is mounted in the radial direction, and is arranged towards the inner wall of the workpiece. The device can synchronously machine multiple peripheral blind holes or through holes in the inner cavity of the part, needs no extra fixture in machining to achieve the clamping convenience, and can automatically and quickly center to greatly improve the machining efficiency.

Description

technical field [0001] The invention relates to a machine tool processing device, in particular to a multi-cutter processing device for inner cavity drilling. Background technique [0002] The machine tool industry is the basic equipment industry of the national economy and the top priority for the development of the equipment manufacturing industry. With the continuous, rapid and steady growth of the national economy, my country's machine tool industry has made considerable development and progress. [0003] Oil-free bearings have the characteristics of high load capacity, impact resistance, high temperature resistance, and strong self-lubricating ability. They are especially suitable for occasions where it is difficult to lubricate and form an oil film such as heavy loads, low speeds, reciprocating or swinging, and have been widely used in metallurgical continuous casting machines, Steel rolling equipment, mining machinery, ships, steam turbines, water turbines, injection...
