Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing technology, specifically relating to a tapping tool for a deep hole drilling machine. Background Technology

[0002] Currently, the cutting tools of deep hole drilling machines can only drill holes. When machining deep hole oil circuit boards, these holes usually have threads at the hole opening. This requires removing the workpiece after machining the deep hole and then changing the machining equipment to tap the hole opening, which is time-consuming and labor-intensive. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a deep hole drilling machine tapping tool that can guarantee stable machining of deep holes and can produce threads.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a tapping tool for a deep hole drilling machine, including an extended tool shank and a shock-absorbing sleeve. The head end of the extended tool shank passes through the shock-absorbing sleeve, and a spring sleeve is fitted on the head end of the extended tool shank. A tap is inserted into the spring sleeve, and the spring sleeve is locked to the extended tool shank by a nut.

[0005] As a preferred technical solution, a cooling hole is provided at the center of the extended tool holder.

[0006] As a preferred technical solution, the shockproof sleeve includes a large sleeve portion and a small sleeve portion.

[0007] As a preferred technical solution, the head of the extended knife bar has a wrench-applying surface.

[0008] Due to the adoption of the above technical solution, this utility model has at least the following beneficial effects: the vibration is avoided when the extended tool bar rotates by the anti-vibration sleeve, and the tap is clamped by the spring sleeve and nut. Using this tool can ensure the stability of the machining and produce the required thread. The machining accuracy is high and the stability is good. It solves the problem that deep hole drilling machines can only drill holes but not tap threads, which helps to improve the machining efficiency and reduce the labor intensity of workers and the risk to product quality.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0018] like Figure 1 and Figure 2 As shown, the tapping tool for a deep hole drilling machine includes an extended tool shank 1 and a shock-absorbing sleeve 2. The shock-absorbing sleeve 2 is fixed to the machine tool. The head end of the extended tool shank 1 passes through the shock-absorbing sleeve 2. A spring sleeve 3 is fitted onto the head end of the extended tool shank 1. A tap 4 is inserted into the spring sleeve 3. The spring sleeve 3 is locked to the extended tool shank 1 by a nut 5.

[0019] Referring to the figure, in this embodiment, the shockproof sleeve 2 includes a large sleeve portion 21 and a small sleeve portion 22, which can improve the shockproof effect.

[0020] Referring to the figure, to facilitate the disassembly and installation of the extended tool holder 1, the head of the extended tool holder 1 has a wrench-applying surface 11. Referring to the figure, a cooling hole 12 is provided at the center of the rod body of the extended tool holder 1 to facilitate the cooling of the tool by cooling water during the machining process.

[0021] The method of using this tool is as follows: Install the extended tool bar 1 on the machine tool and let its head pass through the anti-vibration sleeve 2. Put the spring sleeve 3 on the head of the extended tool bar 1, use the nut 4 to fasten the spring sleeve 3, insert the tap 4 into the spring sleeve 3, and then tighten the nut 5 with a wrench. Start the machine tool to start tapping.

[0022] This utility model uses a shockproof sleeve to prevent vibration when the extended tool holder 1 rotates, and uses a spring sleeve 3 and a nut 5 to clamp the tap 4. Using this tool can ensure the stability of the machining and produce the required threads. It has high machining accuracy, good stability, and is easy to install and use. It solves the problem that deep hole drilling machines can only drill holes but not tap threads, improves machining efficiency, and reduces quality risks.

[0023] The above description is merely an illustrative embodiment of this utility model and is not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model.
