Inner arc turning device

Abstract

The invention relates to an inner arc turning device and belongs to the technical field of inner arc turning devices. The inner arc turning device comprises a rocker arm shaft, a worm wheel, a cutter, a worm, a fixing base, a rocker arm, a worm wheel shaft and a cutter rest. The fixing base is installed on a middle carriage of a turning lathe, the rocker arm shaft is installed on the upper portion of one end of the fixing base, and the worm is manufactured at one end of the rocker arm shaft. A worm wheel shaft fixing block is manufactured at the end, with the rocker arm shaft, of the fixing base, the worm wheel shaft is fixedly installed on the worm wheel shaft fixing block, and the worm wheel is installed on the worm wheel shaft through a bearing. The cutter rest and the cutter are fixedly installed on the worm wheel. According to the inner arc turning device, the precision and the machining reliability of a machined inner arc are ensured through the worm wheel and worm cutter feeding structure, the cutter feeding amount is large, the machining efficiency is high, and the investment and machining cost of equipment is greatly saved. The problems that when an existing inner arc is machined on a general lathe, arc surface cutter feeding is difficult to control manually, precision cannot be ensured, the machining forming rate is very low, the technical requirement for machining personnel is very high are solved.

Description

technical field [0001] The invention relates to an inner arc turning processing device, which belongs to the technical field of inner arc turning processing devices. Background technique [0002] Inner arc workpieces are used in many places of mechanical devices, such as the blade cover shell of the water pump, the end cover of the engine, etc. The processing of the inner arc surface of the inner arc workpiece is relatively difficult. In the existing processing technology, when the workpiece is processed on a common car, because the processed workpiece is not smooth, and the arc surface feed is difficult to control manually, the accuracy cannot be guaranteed, and the processing molding rate is very low. , The technical requirements for processing personnel are very high. In order to solve this problem, the existing inner arc workpieces are all processed on CNC lathes, but the interference of cutting tools on CNC lathes is relatively large, the amount of cutting is relativel...

Problems solved by technology

The processing of the inner arc surface of the inner arc workpiece is relatively difficult. In the existing processing technology, when the workpiece is processed on a common car, because the workpiece is not smooth, and the arc surface feed is difficult to control manually, the accuracy cannot be guaranteed, and the processing molding rate is very low. , the technical requirements for processing personnel are very high

In order to solve this problem, the existing inner arc workpieces are all processed on CNC lathes, but the interference of cutting tools on CNC lathes is relatively large, the amount of cutting is relatively small, the processing efficiency is low, and the processing cost is high.
