Annular groove machining cutter tool used for vertical drilling machine

Abstract

The invention discloses an annular groove machining cutter tool used for a vertical drilling machine, comprising a cutter bar, wherein a limiting locknut is connected in the middle of the cutter bar; a spindle sleeve is fixedly connected at the lower part of the cutter bar; a cutter disc is installed at the bottom of the cutter bar; cutter bits arranged symmetrically are installed at the bottom of the cutter disc; an outer sleeve is supported on an excircle of the spindle sleeve through a bearing; and three claw locating sleeves are fixedly connected at the bottom of the outer sleeve. By adopting the annular groove machining cutter tool, machining of annular grooves of six sizes can be completed in one step, the sizes are favorable in consistency, and the precision is easy to control; a processed part is convenient to replace, and the auxiliary time of replacing the processed part is short; the annular groove machining cutter tool is located conveniently and accurately; the groove depth is not influenced by the overall thickness of a hydraulic valve plate; the labor intensity is low and the production efficiency is high. Compared with the annular groove machined on a lathe, the annular groove has the quality which is easily ensured and the production efficiency which can be improved by 2-3 times.

Description

technical field [0001] The invention relates to a tool for processing ring grooves, in particular to a tool for processing ring grooves for vertical drills. Background technique [0002] At present, the sealing ring grooves of hydraulic valve plates are usually processed by lathes. There are the following technical problems in lathe machining of the sealing ring groove: 1) the depth of the ring groove is not easy to control, and the depth dimension of the ring groove is often unqualified, resulting in the scrapping of the entire hydraulic valve plate, thereby reducing the yield of the hydraulic valve plate; 2) Machining sealing ring grooves of hydraulic valve plates on a lathe is difficult and takes a long time to clamp the workpiece; 3) The depth of the ring groove is greatly affected by the thickness of the plate, which may easily cause inconsistent depth dimensions. It takes a long time to adjust the plate, resulting in low processing efficiency; 4) Machining the sealing...

Problems solved by technology

There are the following technical problems in lathe machining of the sealing ring groove: 1) the depth of the ring groove is not easy to control, and the depth dimension of the ring groove is often unqualified, resulting in the scrapping of the entire hydraulic valve plate, thereby reducing the yield of the hydraulic valve plate; 2) Machining sealing ring grooves of hydraulic valves on a lathe is difficult and takes a long time to install the workpiece; 3) The depth of the ring groove is greatly affected by the thickness of the ring, which may easily cause inconsistent depth dimensions

It takes a long time to adjust the plate, resulting in low processing efficiency; 4) Machining the sealing ring groove of the hydraulic valve plate on the lathe requires a high-level technician to grind the tool, which requires a high technical level of the technician; 5) Machining sealing ring grooves of hydraulic valves on a lathe is labor-intensive and low in production efficiency
