As an optimized proposal of the utility model, the front end of the blade and the positioning surface are integrated into a whole, and the outside of the blade supporting position forms an arc structure.

As a preferred scheme of the utility model, the end face slot blade still includes cutter body and link, and the cutter body laminates mutually with the groove cutter arbor surface, and passes through the detachable connection of screw between cutter body and the groove cutter arbor.

As a preferred scheme of the utility model, the link is located cutter body one end, and the link is embedded in the groove cutter arbor.

As an optimized scheme of the utility model, blade front end and locating surface link to each other with the cutter body, and blade front end and locating surface are located the same one end of cutter body.

As an optimal scheme of the utility model, two the relative setting of terminal surface slot blade along groove cutter arbor center department.

As an optimized proposal of the utility model, the groove cutter bar and the clamping handle are integrally formed.

The beneficial effects of the utility model are that, compare with prior art: width behind the side slot blade mistake tooth is unanimous with the side slot width through adjusting two, can process out the side slot dimensional requirement that the customer required, in operation process, only need to install the side slot blade and can use on the groove cutter arbor, and the side slot blade directly is changed after the side slot blade wearing and tearing and is just right, need not other operations, assistance-time when can shorten the tool changing. In addition, the end face groove blade only needs to be slightly modified from a standard blade, and the consumption cost and the purchase period of the cutter can be reduced.

Fig. 1 is a schematic structural diagram of the present invention;

FIG. 2 is a cross-sectional view of M-M of FIG. 1;

reference numbers in the figures: the cutting tool comprises a clamping handle 1, a groove cutter rod 2, an end face groove blade 3, a blade front end 3-1, a blade supporting position 3-2 and a blade positioning surface 3-4.

Detailed Description

The following describes embodiments of the present invention in detail with reference to the accompanying drawings.

As shown in fig. 1-2, a small-diameter end face grooving cutter comprises a grooving cutter rod 2 and a clamping handle 1 which are connected, wherein one end of the grooving cutter rod 2 is connected with the clamping handle 1; two end face slot blades 3 are arranged on the slot cutter rod 2, and the two end face slot blades 3 are arranged along the circumference of the center of the slot cutter rod 2; the end face grooving blade 3 is arranged on the blade supporting position 3-2 through the front end 3-1 of the blade, and the other end of the end face grooving blade is bent inwards towards the center of the grooving blade rod 2; the slotted knife rod 2 and the clamping handle 1 are integrally formed.

The width between two terminal surface groove blades 3 is the same with the width of the terminal surface groove of will cutting to in the cutting process of two terminal surface groove blades 3, can carry out cutting process to the lateral wall of terminal surface groove both sides, two terminal surface groove blades 3 of installation carry out the staggered teeth and arrange.

The end face groove blade 3 is formed by processing a standard groove blade, the blade supporting position 3-2 is ground to form a bending structure, the two end face groove blades 3 are used for cutting end faces with small diameters, the two end face groove blades 3 simultaneously cut inner walls of two sides, and the blade supporting position 3-2 is inwards bent towards the center of the groove cutter bar 2 so that the blade supporting position 3-2 does not interfere with the inner diameter of the end face groove.

The end face slot blade 3 comprises a blade positioning face 3-4, the blade positioning face 3-4 is attached to the surface of the slot cutter rod 2, and the end face slot blade 3 is detachably connected with the slot cutter rod 2 through a screw.

The blade positioning surface 3-4 and the front end 3-1 of the blade are integrally formed, the blade positioning surface 3-4 enables the end surface groove blade 3 to have better stability after the screw is screwed down, the blade positioning surface 3-4 increases the contact area between the whole end surface groove blade 3 and the groove cutter rod 2, and the degree of freedom of the end surface groove blade 3 on the groove cutter rod 2 is limited.
