[0023] Attached below Figure 1-3 The detailed structure of this embodiment is described:
[0024] This embodiment is described by setting two shaft support mechanisms as an example: figure 1 As shown, an automatic installation and positioning device for large-diameter shaft parts for lathes includes a first shaft support mechanism 1, a second bearing support mechanism 2, a screw screw 5, a servo motor 3, a coupling 4, and a screw fixing device 7. The power output end of the servo motor 3 is connected to one end of the screw screw through the coupling 4, and the other end of the screw screw is rotated and set on the screw fixing device 7. The first shaft support mechanism 1 and the second bearing support mechanism 2 are respectively Set on the screw 5 and driven by the servo motor 3 .
[0025] The first shaft support mechanism 1 and the second bearing support mechanism 2 described above have the same structure, such as figure 2 As shown, each set of shaft support mechanisms is mainly composed of a lifting frame 8, a lifting assembly 9, a moving frame 12, an opening and closing nut 14, an opening and closing nut control pin 15, an opening and closing nut control shaft 11, a roller bearing 13, a connecting bolt 10, a guide rail 6. The adjusting nut 16, the supporting roller 19, and the control shaft rotating handwheel 17 are composed; the opening and closing nut control shaft 11, the control shaft rotating handwheel 17, the opening and closing nut control pin 15 and the guide rail 6 are installed on the moving frame. The opening and closing drive assembly for controlling the opening and closing nut 14 to disengage or engage with the screw screw 5 .
[0026] In this embodiment, as figure 2 As shown, the moving frame 12 has a concave-shaped structure, and the lower end of the lifting frame 8 has a convex portion that matches the concave-shaped structure, and is clamped on the upper end of the moving frame 12 through the convex portion, and the lifting components 9 are distributed on the moving frame. On both sides of 12, the lower end of the lifting assembly 9 is connected and fixed with the moving frame structure 12 by connecting bolts 10, and the upper end is connected with the lifting frame 8 through the pin shaft 18; in this embodiment, the lifting assembly 9 adopts a hydraulic cylinder.
[0027] In this embodiment, as figure 2 As shown, two sets of roller bearings 13 are provided on both sides of the bottom end of the mobile frame structure 12, and a set of open and close nuts 14 are provided in the middle of the bottom to cooperate with the screw screw 5, and the open and close nuts 14 are connected to the mobile frame structure 12 through the guide rails 6. connect.
[0028] In this embodiment, as figure 2 As shown, the opening and closing nut 14 is provided with an opening and closing nut control pin 15, the lower end of the opening and closing nut control pin 15 is connected to the opening and closing nut 14, and its upper end passes through the moving frame structure 12 and the opening and closing nut control shaft 11 The screw on the circumferential surface of the shaft 11 Therefore, when the opening and closing nut control shaft 11 rotates, the opening and closing nut 14 is driven to move along the guide rail by the opening and closing nut control pin 15 to realize the disengagement or engagement of the opening and closing nut and the screw screw.
[0029] In this embodiment, as image 3 As shown, both ends of the opening and closing nut control shaft 11 are connected with the moving frame structure 12 through the adjusting nut 16 , and one end of the opening and closing nut control shaft 11 is connected to the control shaft rotating handwheel 17 .
[0030] The specific installation process of the present invention is as follows:
[0031] like figure 1 As shown, the right end of the screw screw 5 is fixedly connected with the lathe bed through the screw fixing device 7, the servo motor 3 is fixedly connected with the machine bed through its own flange, and the servo motor 3 transmits the power through the coupling 4. To the screw screw 5, the screw screw 5 is connected to the opening and closing nut 14 at the bottom of the first shaft support mechanism 1 and the second shaft support mechanism 2. At this time, the opening and closing nut 14 and the screw screw 5 are in an engaged state, driving the first shaft support mechanism 1. The shaft support mechanism 1 and the second shaft support mechanism 2 move simultaneously.
[0032] like figure 2 As shown, by controlling the control shaft in the first shaft support mechanism 1 or the control shaft in the second shaft support mechanism 2 to rotate the handwheel 17, the control shaft 11 of the opening and closing nut is driven to rotate, and the spiral groove on the surface of the control shaft 11 of the opening and closing nut drives the two opening and closing The nut control pin 15 translates to both sides, the translation of the opening and closing nut control pin 15 drives the opening and closing nut 14 to separate to both sides, and the opening and closing nut 14 and the screw screw 5 are in a disengaged state, then the first shaft support mechanism 1 or the second The two-axis support mechanism 2 will not translate with the rotation of the screw 5, so as to achieve the purpose of adjusting the distance between the first-axis support mechanism 1 and the second-axis support mechanism 2 and adapting to the positioning and installation of parts with different lengths .
[0033] like figure 2 As shown, two support rollers 19 are installed on the upper part of the first shaft support mechanism 1 and the second shaft support mechanism 2 to bear the weight of the parts, and can follow the rotation of the parts to reduce friction.
[0034] like figure 2 As shown, in the first shaft support mechanism 1 and the second shaft support mechanism 2, there are two sets of roller bearings 13 on both sides of the bottom end of the moving frame 12, and the roller bearings 13 are pressed on the guide rails of the lathe bed.
[0035] like figure 2As shown, in the first shaft support mechanism 1 and the second shaft support mechanism 2, the moving frame 12 and the lifting frame 8 are connected through the hydraulic cylinder 9, the hydraulic cylinder 9 is fed with hydraulic oil, the piston rod starts to rise and fall, and the lifting frame structure is driven by the pin shaft 18. 8. Lift up and down, so as to ensure that the shaft parts on the first shaft support mechanism 1 and the second shaft support mechanism 2 are aligned with the lathe chuck.
[0036] It should be noted that the above-mentioned embodiment takes the provision of two shaft support mechanisms as an example. Of course, when the processed bearing parts are large and long, those skilled in the art can also set up three or more as required.
[0037] It should be noted that although the present invention has been described by the above-mentioned embodiments, the present invention may also have other various embodiments. Without departing from the spirit and scope of the present invention, those skilled in the art can obviously make various corresponding changes and modifications to the present invention, but these changes and modifications should belong to the appended claims of the present invention and their equivalents within the scope of protection.
