Abstract

The utility model relates to an end surface grooving special cutter, in particular to an end surface grooving special cutter on a digital control vertical lathe, wherein a cutting blade is welded witha cutting bar, the two sides of the edge of the cutting blade are grinded with rounded corners, and the cutting blade adopts hard alloy. As the material of the cutting blade adopts the hard alloy, the durability of the cutting blade is improved. Since the cutting blade is welded with the cutting bar, the reliable connection of the cutting blade and the cutter is guaranteed. When disc elements which have larger diameter, and are provided with grooves on the end surfaces and convex objects on the middles are processed, the geometrical parameters of the cutter can be grinded according to the requirements of to-be-processed elements, the multistep cutting processing can be finished through one-time installation, the times to replace the cutter are reduced, and the shape tolerance of the elements is guaranteed, thereby improving the processing efficiency. The end surface grooving special cutter is especially suitable for disc elements which have large diameter and are provided with grooveson the end surfaces thereof.

Description

Numerical control vertical lathe end face grooving cutter

One, technical field

The utility model relates to the end face grooving dedicated tool on a kind of end face the grooving dedicated tool, particularly numerical control vertical lathe.

Two, background technology

The end face grooving cutter structure of selling in the market and using is: knife bar and blade are the branch body structures, and this type of cutter and cutter bar length is less than 200mm, and blade can not carry out sharpening, is only applicable to process the less part of diameter.And bigger for the processing diameter, end face has groove, when particularly there is the disk-like accessory of convex object the centre, need at first after processing on the vertical lathe, on CNC milling machine, carry out the secondary clamping, carry out the milling groove, not only can not guarantee the form and position tolerance of part, working (machining) efficiency is lower simultaneously.

Three, summary of the invention

It is a kind of simple in structure, compact that the purpose of this utility model is to provide, and reduces number of changing knife, can be at the get on the bus CNC turning tool of surface groove of large-sized numerical control vertical lathe.

Technical scheme is: the utility model blade and knife bar weld together.Knife-blade two side grindings have fillet, the material selection carbide alloy.

The utility model has improved the durability of blade because blade material is selected carbide alloy for use.Blade and knife bar weld together, and have guaranteed that the connection of blade and cutter hub is reliable.Bigger for the processing diameter, end face has groove, when particularly the disk-like accessory of convex object being arranged, the geometric parameter of cutter can carry out grinding according to the requirement of institute's processing parts, only need a clamping just can finish the multiplex (MUX) and go on foot machining, reduce number of changing knife, guaranteed the form and position tolerance of part, thereby improved working (machining) efficiency.The utility model is specially adapted to major diameter, the fluted disk-like accessory of end face.

Four, description of drawings

Fig. 1 is numerical control vertical lathe grooving cutter schematic diagram.

Fig. 2 is the partial sectional view of the right view of Fig. 1.

Fig. 3 is the vertical view of Fig. 1.

Fig. 4 is the I place partial enlarged drawing among Fig. 2.

Five, the specific embodiment

Embodiment 1:

As Fig. 1 is a kind of specific embodiment structural representation of the present utility model, comprises blade 1 and knife bar 2, the middle carbide alloy that blade 1 adopts.What knife bar 2 adopted is the 45# forged steel, heat treatment (hardness is HRC30～40), and its cross sectional dimensions is 40 * 40 millimeters, length is 280 millimeters.

Reliable in order to guarantee that blade 1 and knife bar 2 connect, blade 1 is welded on the knife bar 2.

Blade 1 blade two side grindings have fillet 3 and fillet 4.

In the piston cap of working fluid platen braking, this part belongs to the major diameter disk-like accessory, and a cannelure is arranged on end face, and well width is approximately 25mm, and there is fillet the trench bottom both sides.

Before using this cutter, can be by the fillet size reconditioning cutter blade both sides fillet of part trench bottom surfaces, consistent with part trench bottom surfaces fillet.In process, at first to cut from the centre of groove, surplus is left in groove side surface and bottom, finishes the fine finishining of this groove for the last time, forms the trench bottom surfaces fillet with the fillet machined part on the cutter.

Can also simplify part by numerical control program composition like this.

Claims

1, numerical control vertical lathe end face grooving cutter comprises: blade (1), knife bar (2) is characterized in that: blade (1) is welded on the knife bar (2).

2, numerical control vertical lathe according to claim 1 end face grooving cutter is characterized in that: blade (1) blade two side grindings have fillet (3,4).
