[0002] Vertical lathes are large-scale mechanical equipment used to process large and heavy workpieces with large radial dimensions and relatively small axial dimensions and complex shapes, such as cylindrical surfaces, end faces, conical surfaces, cylindrical holes, conical holes, etc. of various discs, wheels and sleeves. They can also be used for threading, spherical surface turning, profiling, milling and grinding with the help of additional devices.

In the double-column vertical lathe with a reinforcement structure, the material can be fixed on the storage plate through the mounting hole, so as to achieve the purpose of reinforcement, so that the material placement is more stable.

[0004] However, during the process of processing the workpiece, it is not convenient to precisely adjust the position of the machining head on the vertical lathe, which affects the machining efficiency and accuracy of the workpiece. At the same time, during the machining process, the vibration generated by the outside world and the lathe itself will affect the machining quality of the workpiece. However, the vertical lathe does not have a buffering and shock-absorbing mechanism to reduce the vibration of the lathe. For this reason, we propose a vertical movable double-column lathe.

[0029] The hydraulic cylinder 401 is fixedly installed on the inner top of the frame 2, and the number of hydraulic cylinders 401 is two. The lower end of the hydraulic cylinder 401 is fixedly installed on the connecting plate 402, the mounting frame 405 is fixedly installed on the front of the connecting plate 402, the motor 406 is fixedly installed on the right side of the mounting frame 405, and the output end of the motor 406 is fixedly connected to the threaded rod 407 through a coupling. The two ends of the threaded rod 407 are rotatably connected to the inner side of the mounting frame 405 through bearings. The threaded block 408 is threadedly connected to the outer wall of the threaded rod 407, and the number of threaded blocks 408 is two, and the processing tool head 5 is fixedly installed on the front of the threaded block 408.

[0030] The slide groove 403 is opened on the inner side of the frame 2, the slider 404 is slidably connected to the slide groove 403, the slider 404 is fixedly connected to the side of the connecting plate 402, and the number of the slider 404 and the slide groove 403 are both two and symmetrically arranged on the inner side of the frame 2.

[0031] In this embodiment, by providing an adjustment mechanism 4, the vertical position and horizontal position of the machining tool head 5 are precisely adjusted using a hydraulic cylinder 401 and a threaded rod 407, thereby effectively improving the machining efficiency of the workpiece and improving the machining accuracy of the workpiece.

[0032] Example 2

[0033] like Figure 1-4 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the buffer shock absorbing mechanism 6 includes a fixed base 601, a movable groove 602, a damping block 603, a movable plate 604 and a buffer spring 605, the fixed base 601 is arranged below the mounting base 1, the movable groove 602 is opened at the inner bottom of the fixed base 601, the damping block 603 is slidingly connected to the movable groove 602, one side of the movable plate 604 is hinged to the bottom of the mounting base 1 through a pin shaft, and the other side of the movable plate 604 is hinged to the left side of the damping block 603 through a pin shaft.

[0034] Two ends of the buffer spring 605 are fixedly connected to the inner wall of the movable groove 602 and the right side of the damping block 603 respectively. There are five buffer springs 605 which are evenly arranged in the movable groove 602 .

[0035] The movable groove 602 , the damping block 603 , the movable plate 604 and the buffer spring 605 constitute a buffer part. There are four buffer parts and they are evenly arranged on the inner bottom of the fixed base 601 .

[0037] The following is a detailed description of the working principle of this vertical movable double-column lathe.

[0038] like Figure 1-4 As shown, the workpiece is fixed above the positioning chuck 3. When the vertical position of the machining cutter head 5 needs to be adjusted, the hydraulic cylinder 401 is started to drive the connecting plate 402 to move. Due to the limiting effect of the slider 404 and the slide groove 403, the connecting plate 402 moves in the vertical direction, thereby driving the machining cutter head 5 to move. When the horizontal position of the machining cutter head 5 needs to be adjusted, the motor 406 is started to drive the threaded rod 407 to rotate, so that the threaded block 408 slides in the mounting frame 405, thereby driving the machining cutter head 5 to move horizontally along the direction of the threaded rod 407; when the lathe is vibrated, the distance between the mounting seat 1 and the fixed base 601 is shortened. Due to the hinged effect of the movable plate 604, the movable plate 604 pushes the damping block 603 to slide in the movable groove 602, so that the damping block 603 and the movable groove 602 rub to damp and reduce shock, and at the same time, the damping block 603 pushes the buffer spring 605 to compress and buffer the vibration.
