Abstract
The utility model relates to a circular-hole chamfering tool for a machine tooling center, which is used for solving the problems of an ordinary circular-hole chamfering tool that the processing efficiency is low and the tool loss is large. The utility model adopts the technical scheme that: the circular-hole chamfering tool for the machine tooling center consists of a cutter body and a cutter blade, wherein the cutter body is provided with an axial plane, a cutter blade groove and a press plate are arranged on the axial plane, the cutter blade is in a triangular shape, the cutter blade groove is matched with the shape of the cutter blade, and the cutter blade is embedded inside the cutter blade groove and is fixed by the press plate. The circular-hole chamfering tool ahs the following main characteristics that: 1) the processing of two sides at a time of clamping can be realized when end surfaces at two sides of a circular hole are chamfered; and 2) the structure is simple and is easy to realize. The size of the cutter blade is small, and the shape of the cutter blade is simple; and leftover corners of a scrapped tool can be modified to use, so the investment cost of the tool can be greatly reduced.
Description
Technical field
The utility model relates to a kind of cutter, and particularly the machine tooling center adds used dedicated tool in man-hour in upper and lower chamfering or semicircle orifice chamfering to the workpiece circular hole, belongs to the Machining Technology field.
Background technology
The work in-process heart adds man-hour to upper and lower chamfering of the circular hole of workpiece and semicircle orifice chamfering at present, usual method is as shown in Figure 3: according to the requirement of circular hole chamfering on the work piece, selection has the drill bit of suitable drift angle, processes by the circular interpolation program of setting.Above-mentioned processing mode once is installed and can only finishes the processing of workpiece circular hole one side chamfering, and circular hole opposite side chamfering need will be installed again and could process after the workpiece upset.The problem that this method exists is: 1. adopt the workpiece upset to be installed and the processing mode of circular interpolation, production efficiency is low, and increases operator's labour intensity; 2. higher to the quality requirement of used drill bit cutter, if tool wear can directly influence the workpiece to be machined chamfer quality, for the workpiece of batch machining, the cutter consumptive material is big, increases production cost.
The utility model content
The utility model is used to solve the defective of above-mentioned prior art and provides a kind of working (machining) efficiency height, the cost of charp tool to drop into low machine tooling center circular hole chamfering tool.
The alleged problem of the utility model solves by the following technical programs:
A kind of machine tooling center circular hole chamfering tool, its special feature is: it is made up of cutter hub and blade, cutter hub is provided with axial plane, described axial plane is provided with insert groove and pressing plate, described blade is a triangle, insert groove and blade shapes coupling, blade is inlaid in the insert groove and by pressing plate and fixes.
Above-mentioned machine tooling center circular hole chamfering tool, described blade, insert groove, pressing plate are provided with two groups, and their symmetries are installed in the upper and lower part of axial plane.
The utility model improves at the common circular hole chamfering tool of machining center working (machining) efficiency problem low, that the cutter loss is big, has designed a kind of dedicated tool that is suitable for work in-process heart processing circular hole chamfering.The main feature of this dedicated tool is as follows: 1. can realize once being installed to the chamfer machining of circular hole both sides end face, both sides processing, avoid upset waste in the man-hour that workpiece caused, enhance productivity, and reduced operator's labour intensity; 2. simple in structure, be easy to realize.Little, the simple shape of blade volume can utilize the leftover pieces transformation of scrapping cutter to use, and greatly reduces the input cost of cutter.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cross-sectional view of Fig. 1;
Fig. 3 is the schematic diagram of cutter processing circular hole chamfering before improving.
Label is as follows in the accompanying drawing: 1. cutter hub, 2. axial plane, 3. pressing plate, 4. blade, 5. insert groove, 6. workpiece, 7. bolt, 8. drill bit.
The specific embodiment
Referring to Fig. 1, Fig. 2, the utility model comprises the employed cutter hub 1 of machining center, and cutter hub top is connected with machine tool chief axis.Cutter hub is provided with axial plane 2, and insert groove 5 is set on axial plane, and blade is a triangle, the form fit of insert groove and blade 4, and blade is inlaid in the insert groove.Also be provided with pressing plate 3 on the axial plane, pressing plate is fixing by bolt 7, tights a bolt, and blade is promptly fixed by pressing plate.Blade 4, insert groove 5, pressing plate 3 are provided with two groups, and their symmetries are installed in the upper and lower part of axial plane, are respectively applied for the both sides chamfering of processing circular hole.The angle α that blade cutting edge and cutter hub axis are constituted and the chamfer angle of workpiece circular hole are consistent.
When the utility model is used to process the circular hole chamfering, blade according to workpiece circular hole size and chamfering requirement selection suitable dimension and angle, blade is installed on the cutter hub, spindle centerline adjusted to the center line of workpiece overlap, need not patching plug program, cutter hub is processed a side chamfering by blade with main axis rotation; Process the back cutter hub and move axially, again by another blade to workpiece opposite side chamfer machining, the both sides chamfer machining realizes once being installed.
