Problems solved by technology

However, similar large valve body rotary workpieces with a rotary diameter of D3680mm and a length of 5540mm require at least a large horizontal lathe with a rotary diameter of 4 meters to realize processing. However, this large special machine tool is very low in use and economical. It is not high, and few companies will purchase this type of equipment; secondly, the shape of large valve bodies is generally irregular, and a special counterweight needs to be adjusted to process such workpieces on a horizontal lathe, so that the dynamic balance of the workpiece can reach an ideal state when rotating, otherwise the processing will The workpiece will vibrate, it is difficult to achieve uniform turning, and eventually the surface finish of the workpiece cannot meet the requirements

Embodiment Construction

[0018] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0019] A kind of sleeve shape rolling processing tool of the present invention, as figure 1 , 2 As shown, it consists of a set boring body 1 and several rolling cutter heads 3. The boring body 1 includes a base 11, several ribs 12 and a ring 13; one end of several ribs 12 is evenly arranged vertically along the periphery of the base 11, and the other end of several ribs 12 and one side of the ring 13 Connection; the other side of the ring 13 is equidistantl...

Abstract

The invention relates to a sleeve-shaped rolling processing tool, which includes a sleeve boring body and several rolling cutter heads; the sleeve boring body includes a base, several bars and rings, and one end of the bars is evenly arranged vertically on the base Along the periphery, the other ends of several ribs are connected to one side of the ring; the other side of the ring is equally spaced with tool holder grooves corresponding to the number of rolling cutter heads, and the opening direction of the tool holder grooves points to the center of the ring. The rolling cutter head is fixed on the inner ring of the ring through the cutter holder groove. The sleeve-shaped rolling processing tool provided by the invention is installed on the main shaft of the machine tool through the base, and the tool rotating cutting is used instead of the machine tool rotating cutting processing method, and the roller squeezes the surface of the workpiece to achieve a smooth surface of the workpiece.

Description

technical field [0001] The invention relates to the field of mechanical processing, and more specifically relates to a sleeve-shaped rolling processing tool for the journal of a large-scale valve body. Background technique [0002] At present, the high-precision journal protruding from both ends of a large valve body in machining is thin and requires very high coaxiality. The commonly used processing technology is turning first and then grinding on a large horizontal lathe. The end faces of the shaft diameter protruding from both ends of the large valve body use a clamping scheme of one clamp and one top on a large horizontal lathe, and use the processing technology of turning first and then grinding to meet the requirements of the drawing. However, similar large valve body rotary workpieces with a rotary diameter of D3680mm and a length of 5540mm require at least a large horizontal lathe with a rotary diameter of 4 meters to realize processing. However, this large special m...
