Problems solved by technology

[0003] The purpose of the present invention is to solve the problems of many procedures, low work efficiency, high production cost and difficult to guarantee the product quality existing in the processing of the outer circular surface of the irregular workpiece in the prior art, and to provide a simple process, high work efficiency and low production cost. Cylindrical rapid prototyping tools with low cost and good product quality
On the other hand, since the axial length of the tool holder is significantly longer than the existing structure, it can process longer workpieces, which solves the defect that the tools in the prior art can only process shorter workpieces

Embodiment 1

[0029] in such as figure 1 In the shown embodiment 1, a cylindrical forming combination cutter includes a knife handle located on the centerline of tool rotation, the lower end of the knife handle 1 is provided with a tool holder disc 2, and the axial direction of the outer edge of the tool holder disc is upward There are several tool racks for fixing processing tools. The tool racks include a pair of cutting racks 3 arranged on both sides of the tool rotation centerline. The ends of the cutting racks away from the tool holder disc are respectively provided with cutter heads pointing to the tool rotation center. The outer circle cutting knife in the line direction, the said outer circle cutting knife comprises the outer circle rough cutting knife 4 and the outer circle fine cutting knife 5, and the outer circle rough cutting knife and the outer circle fine cutting knife are respectively arranged on the two sides of the tool rotation center line On the cutting frame, the outer ...

Embodiment 2

[0031] The cross-section of the cutting frame in Example 2 is fan-shaped, and the cross-section of the cutting frame is fan-shaped. The cutting frames on both sides are symmetrically arranged with the center line of the tool rotation as the axis. The surface is on the same central plane of the tool, and the outer circular cutting knife is inclined on the cutting frame. set screw. The angle between the outer circle cutting knife and the cutting frame is 45 degrees, the cross section of the handle of the outer circle cutting knife is rectangular, and the side of the knife handle of the outer circle fine cutting knife near the tool holder disc is provided with a sawtooth structure 14, and the cutting frame There is a corresponding sawtooth structure on the joint surface with the tool handle. The tooth tip angle of the sawtooth structure is 90 degrees, and the length of the slope on both sides of the tooth tip is 0.5 mm. The distance is greater than the length of cutting frame, a...

Embodiment 3

[0033] A pair of rolling frames 15 (see Figure 8 ), the end of the rolling frame far away from the knife holder disc is provided with a rolling device 16 protruding toward the direction of the tool rotation centerline (see Figure 5 ), the distance between the rolling device and the turret disc is smaller than the distance between the cutter head of the outer round fine cutting knife and the turret disc. The rolling device includes a cylindrical ball fixing sleeve 17 arranged vertically with the rolling frame. The ball fixing sleeve is provided with an external thread, and the ball fixing sleeve is screwed with the rolling frame through the external thread. There is an opening, the steel ball 18, the steel bowl 19 and the compression spring 20 are arranged in sequence in the ball fixing sleeve, and one end of the compression spring is connected to the adjusting screw 21, the diameter of the opening end of the ball fixing sleeve is smaller than the diameter of the steel ball, ...

Abstract

The invention discloses a cylindrical rapid prototyping tool. The lower end of the tool handle is provided with a tool rest disk. The outer edge of the tool holder disk is provided with a pair of cutting frames arranged on both sides of the tool rotation center line. One end is respectively provided with an outer circular cutting knife with a cutter head pointing to the direction of the center line of the tool rotation. The outer circular cutting knife includes an outer circular rough cutting knife and an outer circular fine cutting knife. On the cutting frame on both sides, the cutting frame between the tool holder disc and the outer circular cutting knife is provided with a fixed groove in the axial direction, and the end face cutting knife is arranged between the fixed grooves of the cutting frame on both sides. 。 It effectively solves the problems of many procedures, low work efficiency, high production cost and difficulty in guaranteeing product quality in the prior art when processing the outer circle of irregular workpieces. The surface has the substantial effects of simple process, high work efficiency, low production cost and good product quality.

Description

technical field [0001] The invention relates to the technical field of metal cutting, in particular to a cylindrical rapid prototyping tool used for cutting the outer circular surface of irregular workpieces. Background technique [0002] With the continuous progress and development of the industry and the precision design, the parts of the equipment are now complicated and diversified. The structure of many parts is irregular, and it is impossible to use the lathe to process the outer circle of them, so give Processing poses difficulties. At present, the main method of processing the cylindrical surface of irregular workpieces is to use different types of tools to complete the processing through machining centers or boring and milling machines. The problems existing in the prior art are: 1. Too many cutting tools are used, which directly increases the amount of tool changing action for equipment operation, reduces processing efficiency, and wastes resources. The management...
