Flexible honing and reaming device suitable for precision machining of valve element hole of hydraulic multi-way valve

Abstract

The invention discloses a flexible honing and reaming device suitable for precision machining of a valve element hole of a hydraulic multi-way valve, and belongs to the technical field of hydraulic valve body machining. A Z-axis stand column is fixed to the left end of a lathe bed, an X / Y-axis cross-shaped sliding table is installed on the lathe bed in a sliding mode, and an exchange tray is arranged on the X / Y-axis cross-shaped sliding table. The upper end of the Z-axis stand column is slidably connected with a Z-axis main shaft, and a bamboo hat type tool magazine and a Renishaw optical probe system are fixed to one side of the Z-axis stand column. An integral shield is mounted outside the lathe bed, and a cutting fluid supply system with a constant-temperature filtering function is mounted on the inner side of the integral shield; a safety operation door and a numerical control system are arranged on the front face of the integral shield. The device has a workpiece hole automatic centering function and is high in machining precision; a double-tray exchange system and the bamboo hat type tool magazine are adopted, the whole production cycle of the equipment is not stopped, manual intervention for tool changing is not needed in the machining process, and the use efficiency and the production efficiency of the production equipment are improved; the cutting fluid supply system is high in filtering precision, and the machining precision is improved through constant-temperature control.

Description

technical field [0001] The invention relates to the technical field of hydraulic valve body processing, in particular to a flexible honing device suitable for precision machining of valve core holes of hydraulic multi-way valves. Background technique [0002] The reaming process is developed on the basis of traditional honing. It combines the honing processing method and the reaming processing method, so it is also called reaming. In addition, the reaming generally only has one reciprocating action, so it is also called single-stroke honing. [0003] The ream honing is characterized mainly by its ream honing head and the actual honing process. Compared with the traditional honing process, the ream honing head has been set in advance to the final processing size required by the workpiece. Therefore, the cutting process of the hinge honing only needs 1 to 3 reciprocating strokes to complete. The thickness of the metal layer removed by each honing head is 2-20 μm. After ream...

Problems solved by technology

When it is necessary to process a valve body with multiple valve holes in a single plane, multiple clamping and alignment are required, and the degree of flexibility is low. At the same time, there is a risk of affecting the machining accuracy when clamp adjustment;

[0006] Processing products with different apertures requires manual tool replacement, and there is a risk of tool scrapping due to manual tool replacement errors
