Description

Improved whirlwind milling cutter seat

This creative department relates to a whirlwind milling cutter holder, especially an improved whirlwind milling cutter holder with improved structure.

Whirlwind milling is an advanced processing method, which is usually used to mill threads on a workpiece. Whirlwind milling uses a whirlwind milling cutter head for milling, and compressed air is used for chip removal and cooling; the whirlwind milling cutter head It can be easily installed on the existing machine tool only through a whirlwind milling cutter holder, and the structure of the existing machine tool does not need to be changed, which is extremely convenient.

The existing whirlwind milling cutter holder includes a base body, a drive module and a tool shaft assembly. The drive module is arranged on the base body. The tool shaft assembly includes a sliding sleeve and a whirlwind cutter shaft. , The sliding sleeve is cylindrical, and is inserted into the seat body along a setting direction, the sliding sleeve is sleeved on the rotating shaft of the cyclone blade, and the rotating shaft of the cyclone blade is located at the position In the sliding sleeve, the rotary shaft of the whirlwind cutter head is used to install the whirlwind milling cutter head, and the drive module is connected with the rotary shaft of the whirlwind cutter head. It is transmitted to the rotating shaft of the cyclone blade, so that the rotating shaft of the cyclone blade can rotate at a high speed.

However, during the use of the existing whirlwind milling cutter holder, when the rotary shaft of the whirlwind cutter rotates at a high level, unnecessary high-frequency vibration of the sliding sleeve may be caused, resulting in poor accuracy and surface roughness of the workpiece to be processed.

In order to solve the problem that the rotating shaft of the cyclone cutter head rotates at a high speed during the use of the existing cyclone milling cutter holder, unnecessary high-frequency vibration of the sliding sleeve may be caused, resulting in the workpiece to be processed The problem of poor accuracy and surface roughness, the purpose of this creation is to propose an improved cyclone milling cutter block that can prevent unnecessary vibration from the sliding sleeve.

The improved whirlwind milling cutter holder proposed by this creation to solve the technical problem includes: a base body, the base body includes a guide hole; the guide hole penetrates through one of the side surfaces of the base body; a tool shaft assembly, The tool shaft assembly includes a sliding shaft sleeve and a whirlwind blade rotating shaft. The sliding shaft sleeve is cylindrical and penetrates the seat body along a setting direction. The sliding shaft sleeve includes a guide groove. The guide groove is recessed on the outer wall surface of the sliding sleeve and communicates with the guide hole of the seat; the sliding sleeve is sleeved outside the rotating shaft of the cyclone cutter; and a guide post penetrates the guide post. The guide hole of the seat body extends into the guide groove of the sliding shaft sleeve.

In the improved cyclone milling tool holder, the guide groove extends along the installation direction and is elongated.

The efficiency gains obtained by the technical means of this creation are: during the use of the improved cyclone milling cutter seat of this creation, the rotating shaft of the cyclone cutter of the tool shaft assembly extends into the guide groove of the sliding sleeve when it rotates at a high speed. The guide post will play a fixed role to prevent unnecessary vibration of the sliding sleeve and cause poor accuracy and surface roughness of the workpiece to be processed. This creation can maintain the processing accuracy by this.

Fig. 3 is a cross-sectional view of Fig. 2 along the line A-A.

Fig. 4 is a cross-sectional view of Fig. 2 along the line B-B.

In order to understand the technical features and practical effects of this creation in detail, and realize it in accordance with the creation content, the preferred embodiment shown in the figure is further described in detail as follows: as shown in Figures 1 to 3, this article Create a preferred embodiment of the improved cyclone milling cutter seat, which includes a base body 10, a drive module 20, a tool shaft assembly 30 and a guide post 40; among them: as shown in Figures 3 and 4, the seat The body 10 includes a guide hole 11 which penetrates through one of the side surfaces of the base body 10; as shown in FIG. 1, the drive module 20 is provided on the base body 10, wherein the drive module 20 It is the main technical feature of the conventional technology in the technical field that is not the original creation, so I won’t elaborate on it here.

As shown in FIGS. 3 and 4, the tool shaft assembly 30 includes a sliding sleeve 31 and a whirlwind cutter rotating shaft 32; the sliding sleeve 31 is cylindrical and penetrates the seat body along a setting direction 10. The sliding sleeve 31 includes a guide groove 311. As shown in FIG. 3 and 4, the sliding sleeve 31 is sleeved outside the rotating shaft 32 of the cyclone knife plate, and the rotating shaft 32 of the cyclone knife plate is used for mounting A whirlwind milling cutter head is provided, the drive module 20 is connected to the whirlwind knife head shaft 32, and the whirlwind knife head shaft 32 can be driven by the drive module 20 to rotate; as shown in FIGS. 3 and 4, the guide The guide post 40 penetrates the guide hole 11 of the seat body 10 and extends into the guide groove 311 of the sliding sleeve 31.

During the use of the improved whirlwind milling cutter holder of this creation, when the whirlwind cutter shaft 32 of the tool shaft assembly 30 rotates at a high speed, the guide post 40 extending into the guide groove 311 of the sliding sleeve 31 will lift up For the purpose of fixing, it prevents unnecessary vibration of the sliding sleeve 31 from causing poor precision and surface roughness of the workpiece to be processed. This invention can thereby maintain the processing accuracy.

The above are only preferred embodiments of this creation, and do not impose any formal restrictions on this creation. Any person with ordinary knowledge in the relevant technical field can use this creation without departing from the scope of the technical solution proposed in this creation. The equivalent practice of partial changes or modifications made by the technical content disclosed in the creation The embodiments and the content of the technical solution of this creation are still within the scope of the technical solution of this creation.
