Description

Technical Field

[0001] The utility model relates to the technical field of automatic lathes, and more specifically, it relates to a bushing structure for a CNC automatic lathe. Background Technique

[0002] CNC automatic lathes are high-precision automated machine tool equipment with an important position in modern manufacturing. It has many remarkable advantages. First of all, CNC automatic lathes can achieve a highly automated production process, greatly reducing manual intervention, thereby improving production efficiency and the stability of product quality. In the processing of automotive parts, CNC automatic lathes can quickly and accurately produce various parts with complex shapes.

[0003] At present, the bushing structure for a CNC automatic lathe is an important part of the machine tool. Although the bushing structure seems simple, the quality of its design and manufacturing directly affects the processing performance of the lathe and the product quality.

[0004] However, the structural design of the bushing is unreasonable, such as unreasonable dimensions, inappropriate shapes, etc., which cannot provide sufficient guidance and support, thus affecting the processing accuracy and the normal operation of the equipment. For this reason, a bushing structure for a CNC automatic lathe is proposed to improve the existing problems. Content of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a bushing structure for a CNC automatic lathe.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A bushing structure for a CNC automatic lathe, including a fixing component, and one end of the fixing component is installed with a sleeve component, and the sleeve component and the fixing component are integrally formed.

[0007] Among them, the fixing component includes a fixing main body, the fixing main body is set as a hollow cylindrical structure, a plurality of fixing holes are equidistantly arranged at one end of the fixing main body away from the sleeve component, a fixing groove is opened inside the fixing main body, the shape of the fixing groove is circular, a limiting groove is arranged at one end of the fixing groove away from the fixing holes, the limiting groove is connected with the fixing groove, and a limiting plate is arranged on one side of the limiting groove away from the fixing groove.

[0008] By adopting the above technical solution, a limiting groove is provided at one end of the fixing groove away from the fixing hole, and a limiting plate is provided on one side of the limiting groove away from the fixing groove. The limiting plate enables the mounting member to move within a predetermined range, preventing excessive feeding or retraction, thereby ensuring the accuracy and safety of processing; the existence of the fixing hole increases the contact area and connection points between the guide sleeve and the mounting part, thereby enhancing the integrity and rigidity of the entire structure; the fixing groove can provide a certain elastic deformation space, playing a buffering role and reducing the damage suffered by the guide sleeve when subjected to impact or pressure.

[0009] The present utility model is further configured as: the sleeve assembly includes a sleeve body, the sleeve body is provided as a hollow cylindrical structure, a positioning groove is opened on the side wall of the sleeve body close to the fixing component, the shape of the positioning groove is rectangular, and a heat dissipation hole is opened at the middle position of the side wall of the sleeve body close to the positioning groove.

[0010] By adopting the above technical solution, a heat dissipation hole is opened at the middle position of the side wall of the sleeve body close to the positioning groove. The heat dissipation hole can dissipate the heat generated by the sliding of the guide sleeve structure and the contact part, reducing the influence of heat on the guide sleeve structure; the setting of the positioning groove ensures that the guide sleeve structure can be accurately placed at the predetermined position during installation.

[0011] The present utility model is further configured as: a fourth sleeve groove is opened inside the sleeve body, the shape of the fourth sleeve groove is circular, and a lubricating hole is provided at the end of the fourth sleeve groove close to the limiting plate.

[0012] By adopting the above technical solution, during high-speed machining, the guide sleeve and the mounting member will come into contact and generate friction. Excessive friction will cause movement jamming, affecting the machining efficiency. The lubricating hole can supply lubricating oil sufficiently, and the lubricating oil can lubricate the mounting member and the guide sleeve structure sufficiently. Good lubrication can effectively avoid movement jamming during the machining process.

[0013] The present utility model is further configured as: a third sleeve groove is further provided inside the sleeve body, the third sleeve groove is provided at one end of the fourth sleeve groove away from the lubricating hole, and the third sleeve groove is connected to the fourth sleeve groove.

[0014] The present utility model is further configured as: a second sleeve groove is provided at one end of the third sleeve groove away from the fourth sleeve groove. The third sleeve groove and the second sleeve groove are both circular in shape, and the third sleeve groove is connected to the second sleeve groove.

[0015] The present utility model is further configured as: a first sleeve groove is provided at one end of the second sleeve groove away from the third sleeve groove, and the shape of the first sleeve groove is circular.

[0016] By adopting the above technical solution, the first sleeve groove, the second sleeve groove, the third sleeve groove and the fourth sleeve groove are integrally formed. Before processing, the bushing structure will be sleeved outside the mounting part. During the processing of the mounting part, friction will be generated, and this friction will convert mechanical energy into heat energy. The first sleeve groove, the second sleeve groove, the third sleeve groove and the fourth sleeve groove provide sufficient space for the mounting part, which is conducive to heat dissipation and improves the heat dissipation efficiency.

[0017] In summary, the present application includes at least one of the following beneficial technical effects:

[0018] 1. The heat dissipation holes can dissipate the heat generated by the sliding of the bushing structure and the contact part, reducing the influence of heat on the bushing structure; the setting of the positioning groove ensures that the bushing structure can be accurately placed at the predetermined position during installation.

[0019] 2. The limiting plate can allow the mounting part to move within a predetermined range, preventing excessive feeding or retraction, thereby ensuring the accuracy and safety of processing; the existence of the fixing holes increases the contact area and connection points between the bushing and the mounting part, thereby enhancing the integrity and rigidity of the entire structure; the fixing groove can provide a certain space for elastic deformation, playing a buffering role and reducing the damage suffered by the bushing when it is impacted or pressured.

[0020] 3. During the processing of the mounting part, friction will be generated, and this friction will convert mechanical energy into heat energy. The first sleeve groove, the second sleeve groove, the third sleeve groove and the fourth sleeve groove provide sufficient space for the mounting part, which is conducive to heat dissipation and improves the heat dissipation efficiency.
