Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of milling cutter, specifically relates to a milling cutter for chamfering of SUS product. BACKGROUND

[0002] SUS product refers to a kind of special application stainless steel material. It is mainly composed of chromium (Cr) and nickel (Ni), with excellent corrosion resistance, high strength, high hardness and good processing performance. This material can be used in air, water or chemical medium for a long time without rust, and can withstand high temperature and high pressure environment corrosive medium.

[0003] The milling cutter for chamfering of SUS product in prior art is mostly lack of efficient and convenient protection means except for packaging box for packaging and transportation. In actual working environment, users often directly store the milling cutter in tool box without any protection after completing work, and generally lack of protection awareness of milling cutter. When the milling cutter is placed in tool box without proper protection, it is easy to collide with other tools or hard objects accidentally, and frequent collision not only can cause wear or damage of milling cutter edge, but also can increase the risk of user injury due to accidental exposure of blade, thereby significantly reducing the practical efficiency of milling cutter and safety during use. SUMMARY

[0004] (1) technical problem to be solved

[0005] In view of the deficiencies of prior art, the purpose of the utility model is to provide a kind of milling cutter for chamfering of SUS product, protective sleeve is sleeved on the outside of it, after use, milling cutter body can be automatically withdrawn into protective sleeve under the action of spring, thereby good protection effect is played to milling cutter body.

[0006] (2) technical scheme

[0007] In order to solve the above technical problems, the utility model provides a kind of milling cutter for chamfering of SUS product, including milling cutter body and protective sleeve sleeved on the outside of milling cutter body, the inner end of milling cutter body is fixedly provided with top rod, the top rod is slidably connected through the bottom of protective sleeve, the inner end of milling cutter body is fixedly provided with spring, the other end of spring is fixedly arranged in the inner bottom of protective sleeve.

[0008] Preferably, the two sides of the protective sleeve are provided with limiting holes, the two sides of the milling cutter body are fixedly provided with limiting columns, and the limiting columns are slidably arranged through the limiting holes on the same side.

[0009] Further, the outer end of the top rod is fixedly provided with a top block.

[0010] Further, the outer side of the barrel mouth of the protective sleeve is fixedly provided with a push plate.

[0011] Furthermore, the protective sleeve has a rubber stopper at its opening, and a handle is fixedly provided on the back of the rubber stopper.

[0012] Beneficial effects

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] The system is equipped with a protective sleeve, a spring, and a push rod. The push rod is inserted into the mounting slot of the lathe, and then the protective sleeve is pressed into the mounting slot by the push plate, extending the milling cutter body. Subsequently, the lathe is controlled to clamp the outer side of the protective sleeve, thus fixing the milling cutter body in place. After the protective sleeve is removed, the milling cutter body can be reset by the action of the spring and retracted into the protective sleeve, thereby protecting the milling cutter body.

[0019] This specific embodiment is a chamfering milling cutter for SUS products, and its structural schematic diagram is as follows. Figs. 1-3 As shown, the device includes a milling cutter body 1 and a protective sleeve 2 sleeved on the outside of the milling cutter body 1. The protective sleeve 2 is slidably sleeved on the outside of the milling cutter body 1. A push plate 8 is fixedly installed on the outside of the opening of the protective sleeve 2. The push plate 8 is used by the user to push the protective sleeve 2. A rubber plug 9 is installed at the opening of the protective sleeve 2. The rubber plug 9 is used to plug the opening of the protective sleeve 2 to play a sealing and protective role, preventing other tools or hard objects from getting stuck in the protective sleeve 2. A handle 10 is fixedly installed on the back of the rubber plug 9. The handle 10 makes it easy to pull out the rubber plug 9. A push rod 3 is fixedly installed at the inner end of the milling cutter body 1. The push rod 3 slides through the bottom of the protective sleeve 2. A top block 5 is fixedly installed at the outer end of the push rod 3. The top block 5 plays a limiting role. A spring 4 is fixedly installed at the inner end of the milling cutter body 1. The other end of the spring 4 is fixedly installed at the inner bottom of the protective sleeve 2.

[0020] The protective sleeve 2 is provided with limiting holes 6 on both sides, and the milling cutter body 1 is fixedly provided with limiting columns 7 on both sides, the limiting columns 7 are slidably arranged through the limiting holes 6 on the same side, and the limiting columns 7 and the limiting holes 6 limit the milling cutter body 1.

[0021] Working principle:

[0022] In use, the top rod 3 is inserted into the mounting groove of the lathe and abuts against the top block 5, then the protective sleeve 2 is extruded through the push plate 8 and inserted into the mounting groove of the lathe, and the milling cutter body 1 is extended, then the outer side of the protective sleeve 2 is clamped by the lathe, and the milling cutter body 1 is fixedly installed.

[0023] After use, the protective sleeve 2 is loosened by the lathe, and the protective sleeve 2 is taken out, and the milling cutter body 1 is reset under the action of the spring 4 and is collected into the protective sleeve 2, thereby protecting the milling cutter body 1.

[0024] The above embodiment is a preferred implementation scheme of the utility model, in addition to this, the utility model can be realized in other ways, and any obvious replacement without departing from the technical scheme concept is within the protection scope of the utility model.
