At the same time, in terms of multi-angle adjustment, the existing processes are cumbersome and inefficient, and it is difficult to quickly adapt to different processing requirements. With the rapid change of market demand, the existing machines are also unable to cope in terms of response speed and are difficult to quickly adjust the production plan to meet the diverse needs of customers.

Specific Embodiment

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Refer to Figures 1-3 , an embodiment provided by the present invention: A horizontal double-spindle CNC turning and boring machine, including a processing box 1, a base 2 fixedly connected inside the processing box 1, a cylinder 3 fixedly connected to the top of the base 2, a connecting plate 4 fixedly connected to the output end of the cylinder 3, a rack plate 5 fixedly connected to the outside of the connecting plate 4, a connecting column 8 fixedly connected to the top of the base 2, a rotating rod 7 rotatably connected inside the connecting column 8, a half gear 6 fixedly connected to the outside of the rotating rod 7, diagonal struts 9 rotatably connected to both sides of the connecting column 8, one end of the diagonal strut 9 slidably connected to a sliding sleeve 10, a fixture 23 provided on the top of the base 2, and a replacement component installed on the top of the base 2, and the replacement component is used to replace the fixture 23.

[0025] Specifically, the processing box 1 serves as the main structure of the machine tool, providing stable support and protection for the machine tool. The base 2 ensures the stability of the machine tool during operation. The linear motion of the cylinder 3 can be converted into the linear motion of the rack plate 5, and then transmitted to the half gear 6 through the meshing relationship. The swing of the half gear 6 can then be transmitted to the diagonal strut 9 through the rotating rod 7, so that one end of the diagonal strut 9 slides inside the sliding sleeve 10, thereby driving the top plate 11 to adjust the angle.

[0026] Refer to Figures 1-4, the replacement component includes a top plate 11. The bottom of the top plate 11 is disposed on the top of the base 2. Installation grooves 21 are formed on both sides of the top plate 11. A push rod 14 is slidably connected inside the installation groove 21. One end of the push rod 14 is fixedly connected to a moving plate 16. One end of the moving plate 16 is fixedly connected to a rotating shaft 13. A support rod 17 is rotatably connected inside the rotating shaft 13. One end of the support rod 17 is rotatably connected to a fixing block 19. A spring 15 is sleeved outside the push rod 14. An installation plate 12 is disposed inside the top plate 11. A groove 20 is formed on one side of the installation plate 12.

[0027] Specifically, the push rod 14 is slidably connected inside the installation groove 21, making the movement of the push rod 14 smoother and more precise. The movement of the push rod 14 is converted into the movement of the moving plate 16, providing power for the replacement of the fixture 23. The support rod 17 swings through the rotating shaft 13, thereby driving the fixing block 19 to move out of the groove 20, realizing the release of the fixture 23. At the same time, the fixing block 19 is used to insert into the groove 20 of the installation plate 12, and further the fixture 23 can be fixed on the top plate 11. The spring 15 provides a restoring force for the push rod 14, enabling the push rod 14 to maintain stability.

[0028] Refer to Figures 2-3 , at the corresponding positions on the outside of the rack plate 5, it is meshed and connected with the outside of the semi-gear 6. The top of the sliding sleeve 10 is fixedly connected to the bottom of the top plate 11. The outside of the semi-gear 6 is fixedly connected to the bottom of the top plate 11. The bottom of the top plate 11 is rotatably connected to the top of the connecting column 8. The bottom of the rack plate 5 is slidably connected to the top of the base 2. A moving door 22 is slidably connected to one side of the processing box 1.

[0029] Specifically, through the meshing connection, it can ensure that the linear movement of the rack plate 5 is accurately converted into the rotational movement of the semi-gear 6, thereby realizing the angle adjustment of the top plate 11. The sliding sleeve 10 restricts the movement of the diagonal strut 9, further preventing the top plate 11 from shifting or shaking during the adjustment process. When the semi-gear 6 rotates, the top plate 11 rotates around the axis of the connecting column 8, and then the multi-angle processing function of the machine tool can be realized. By sliding on the top of the base 2, it further ensures that the rack plate 5 remains stable and precise during the linear movement, thus avoiding the influence on the machining accuracy of the machine tool. And the operator can open the moving door 22, and then can perform maintenance work on the machine tool, ensuring the normal operation of the machine tool and extending its service life.

[0030] Refer to Figure 4 , a limiting groove 18 is formed on the inner wall of the groove 20. The outside of the fixing block 19 is slidably connected inside the limiting groove 18. The cross-section of the fixing block 19 is square. One end of the fixing block 19 is inserted into the groove 20. The outside of the moving plate 16 is slidably connected inside the installation groove 21.

[0031] Specifically, the existence of the limit groove 18 increases the stability of the fixing block 19 in the groove 20, preventing it from shaking or falling off when subjected to external forces, enabling the fixing block 19 to better fit the inner wall of the groove 20 when inserted into the groove 20, increasing the contact area and friction force, and improving the fixing stability.

[0032] Working principle: First, when the machine tool starts to work, the telescopic end moves by starting the cylinder 3, thereby driving the connecting plate 4 and the rack plate 5 to perform a linear motion through the telescopic end. The linear motion of the rack plate 5 then causes the semi-gear 6 to rotate. At the same time, driven by the semi-gear 6, the rotating rod 7 is further driven to rotate, and then the top plate 11 undergoes an inclined swing, so that the diagonal strut 9 slides inside the sliding sleeve 10. When the angle of the top plate 11 starts to be adjusted, the fixture 23 has already fixed the workpiece, and through the drive of the top plate 11, the multi-directional angle during processing can be further adjusted;

[0033] Secondly, when the fixture 23 needs to be replaced, an external force is used to push the push rod 14, thereby compressing the elastic force of the spring 15. Thus, the movement of the push rod 14 drives the moving plate 16 to move inside the installation groove 21, and at the same time, the support rod 17 swings. As the support rod 17 swings, it drives the fixing block 19 to gradually move out of the groove 20 and slide along the limit groove 18, so that the fixture 23 can be conveniently replaced.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
