TWM359387U - Improved cutlery combining structure - Google Patents

Description

M359387 V. New description: [New technical field] This creation is about the improvement of a tool joint structure, especially a tool with a replaceable cutting head and an internal thread for alloy steel. [Prior Art] After the actual use of the tool combination structure, the following disadvantages are found: 1. The conventional tool combination structure needs to be fixed by the side fixing screws, but if the side fixing screws are small, it is easy to be damaged, resulting in poor bonding and affecting cutting. Work is going on. 2. The conventional tool combination structure shall grind the cutter head to have a thread locking function, which is not easy to manufacture and the precision grade is not easy to improve. 3. The tool-bonding structure used for % is that the cutter head and the shank are both tungsten-steel-threaded and locked, which is difficult to lock in the case of hard-impact, and is easy to loosen during use. [New content] The main purpose of this creation is to provide a tool-integrated structure modification. It is easier to manufacture and reduce the cost of the tool by using the _locking screw to fix the knife on the shank and the internal thread is alloy steel. High tool joint seam and force life. [Embodiment] 第 Referring to the first and second figures, the creation consists of a cutter head and a stalk lion and a _ 300, wherein one end of the cutter head 1 is provided with a cutter η Γ The end is provided with an outer taper fixing portion 1〇2, a rotation preventing portion 103 and a screw through hole 104, and the inner taper fixing portion 2〇2 is matched with the taper fixing portion (10) outside the cutter head to obtain the concentricity. Also provided to prevent rotation of the rotating portion 2{)3 and the cutter head

Claims (1)

M359387 VI. Scope of application: H field - filling 1 A cutting tool combined with structural improvement, mainly consisting of a shank and a cutter head and a locking screw; the cutter head is provided with a cutting edge at one end and a fixing portion at the other end And the rotation preventing portion is provided with a screw through hole at the center, and the locking screw is screwed through the screw through hole to lock the cutter head on the shank, and if the shank is made of tungsten steel or the like, the internal thread portion can be Changed to alloy steel implanted tools. 2. If the cutting tool combination structure described in the first application of the patent scope is improved, the cutter head may be tungsten steel, or may be high-speed steel or ceramic or semi-ceramic, which may be used as a material for the cutting tool. 3. If the cutting tool combination structure described in the first application of the patent scope is improved, the tool shank may be alloy steel or tungsten steel or high speed steel or other seismic material. 4. If the cutting tool combination structure described in the first application of the patent scope is improved, the cutting edge portion of the cutting head can be made into a flat milling cutter. 5. If the cutting tool combination structure described in item 1 of the patent application is improved, the cutter portion of the cutter head can be made into a reamer. 6. If the cutting tool combination structure described in item 1 of the patent application is improved, the cutter portion of the cutter head can be made into a wire tap. 7. If the cutting tool combination structure described in the first application of the patent scope is improved, the cutting blade portion of the cutting head can be made into a drill bit. 8. If the cutting tool combination structure described in the first application of the patent scope is improved, the cutting blade portion of the cutting head can be formed into a cutting body. 5
