Technical Field

[0001] The utility model relates to the technical field of machine tools, in particular to a turning-milling compound interpolation Y-axis structure. Background Art

[0002] Compound machining is one of the most popular machining processes in the field of mechanical machining. It is an advanced manufacturing technology. Compound machining is to realize several different machining processes on one machine tool. Compound machining is the most widely used and the most difficult. The turning and milling compound machining center is equivalent to a combination of a CNC lathe and a machining center.

[0003] The Y-axis structure of the existing turning-milling compound machine tool is an orthogonal structure, and the overall structural rigidity is poor, which results in a large overturning torque when processing workpieces with a large cutting amount, affecting the processing accuracy of the workpiece. Summary of the invention

[0004] In view of the defects existing in the prior art, the purpose of the present utility model is to provide a turning-milling compound interpolation Y-axis structure to solve the problem of poor overall rigidity caused by the orthogonal structure of the Y-axis structure of the existing turning-milling compound machine tool.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] The present application provides a turning-milling compound interpolation Y-axis structure, which includes a bed, and the turning-milling compound interpolation Y-axis structure also includes a first saddle, a second saddle, a turret device, and a first drive mechanism and a second drive mechanism for respectively driving the second saddle and the turret device to move, wherein the first saddle is obliquely installed on the top surface of the bed, and the first saddle forms a sliding connection with the top surface of the bed along the transverse direction of the bed, and the second saddle is obliquely installed on the top surface of the first saddle, the first drive mechanism is connected to the second saddle, and the turret device is slidably installed on the top surface of the second saddle, and the second drive mechanism is connected to the turret device.

[0007] Furthermore, the first saddle is installed on the top surface of the bed at an angle of 15 degrees to the bottom end surface of the bed, and the second saddle is installed on the top surface of the first saddle at an angle of 30 degrees to the top surface of the first saddle.

[0008] Furthermore, a pair of slide rails arranged in the transverse direction is formed on the top surface of the bed, and the pair of slide rails are arranged in parallel, wherein the height of the slide rail on one side close to the outer edge of the bed is higher than the height of the slide rail on the other side.

[0009] Furthermore, the top end surfaces of the first saddle and the second saddle are respectively integrally formed with bearing seats.

[0010] Furthermore, the first saddle is slidably connected to the top surface of the bed body via a slide rail and a slider, and the second saddle is slidably connected to the top surface of the first saddle via a slide rail and a slider.

[0011] The beneficial effects of the utility model are:

[0012] 1. The first saddle is installed on the upper end surface of the bed in an installation manner that forms an inclined angle with the bottom end surface of the bed, and the second saddle is installed on the top end surface of the first saddle in an installation manner that forms an inclined angle with the top end surface of the first saddle. The first saddle and the second saddle cooperate to form an overall gently inclined inclined structure. Compared with the traditional orthogonal Y-axis structure, it has better rigidity and can meet the requirements of large cutting processing.

[0013] 2. By forming a stepped guide rail design on the bed, the two guide rails can be installed horizontally during the actual installation process. Therefore, the lubricating oil used to lubricate the guide rails can be contained horizontally in the guide rail grooves. The lubricating oil can be better stored and is not easy to spill out. In addition, the lubricating oil can lubricate the entire bottom of the slide rail, which makes the lubrication more sufficient and prolongs the service life of the guide rail.

[0014] 3. A sliding structure consisting of a slider and a slide rail is used between the first saddle and the bed, and between the second saddle and the first saddle. The slider has better stability and greater load-bearing capacity. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] See attached Figure 3 and attached Figure 4 And attached Figure 7 As shown, a pair of slide rails 11 arranged in parallel in the transverse direction are formed at the top of the bed 10. The pair of slide rails 11 are arranged in a high and low manner. Specifically, the installation height of the slide rail 11 on one side close to the outer edge of the bed 10 is higher than the installation height of the slide rail 11 on the other side. From the side, the pair of slide rails 11 are in a stepped installation structure.

[0027] At the same time, by forming a stepped guide rail design on the bed 10, the two slide rails 11 can be installed horizontally during the actual installation process, so the lubricating oil used to lubricate the guide rails can be horizontally contained in the guide rail grooves, the lubricating oil can be better stored and is not easy to spill out, and the lubricating oil can lubricate the entire bottom of the slide rail, the lubrication is more sufficient, and the service life of the guide rail is extended.

[0028] See attached Figure 1 , Attachment Figure 2 And attached Figure 5 As shown, the bottom end of the first saddle 20 is slidably mounted on the pair of slide rails at the top of the bed 10. The first saddle 20 forms a sliding connection with the bed 10 in the transverse direction of the bed 10, and the bottom end surface of the first saddle 20 forms a certain tilt angle with the top surface of the bed 10, that is, the first saddle 20 is installed on the bed 10 in an inclined manner. In some embodiments, the first saddle 20 is tiltedly mounted on the top surface of the bed 10 at an angle of 15 degrees. In addition, the first saddle 20 forms a sliding connection with the top surface of the bed 10 through the slide rails and the sliders. The sliding structure composed of the sliders and the slide rails has better stability and greater load-bearing capacity.

[0029] See attached Figure 1 and attached Figure 2As shown, the second saddle 30 is obliquely mounted on the top surface of the first saddle 20, and the bottom surface of the second saddle 30 forms a sliding connection with the top surface of the first saddle 20 in the Y-axis direction. Similarly, the top surface of the second saddle 30 and its bottom surface form an inclined angle. In some embodiments, the top surface of the second saddle 30 and its bottom surface form an inclined angle of 30 degrees. The first driving mechanism 50 is connected to the bottom surface of the second saddle 30, and is used to drive the second saddle 30 to slide along the first saddle 20. Refer to the attached Figure 5 As shown, in order to facilitate the installation of the first drive mechanism 50, a bearing seat 70 is integrally formed at the top of the first saddle 20, so that the rotating shaft in the first drive mechanism 50 can be directly installed in the bearing seat 70 of the first saddle 20, thereby improving the installation efficiency. In addition, similarly, the second saddle 30 and the top surface of the first saddle 20 are slidably connected by a slide rail and a slider, and the slide structure composed of the slider and the slide rail has better stability and greater load-bearing capacity.

[0030] Continue to refer to the attached Figure 1 and attached Figure 2 As shown, the turret device 40 is slidably mounted on the top surface of the second saddle 30, forming a sliding connection with the second saddle 30 in the Y-axis direction, and the second driving mechanism 60 is connected to the turret device 40 to drive the turret device 40 to slide along the top of the second saddle 30. Figure 6 As shown, for ease of installation, the top end surface of the second saddle 30 is integrally formed with a bearing seat 70, and the rotating shaft in the second driving member can be directly installed in the bearing seat 70 of the second saddle 30, thereby improving installation efficiency.

[0031] In summary, by installing the first saddle 20 on the upper end surface of the bed 10 in an installation manner that forms an inclined angle with the bottom end surface of the bed 10, and at the same time installing the second saddle 30 on the top end surface of the first saddle 20 in an installation manner that forms an inclined angle with the top end surface of the first saddle 20, the first saddle 20 and the second saddle 30 cooperate to form an overall gently inclined inclined structure, which has better rigidity than the traditional orthogonal Y-axis structure and can meet the work requirements of large cutting processing volume.
