Problems solved by technology

combine figure 2 As shown, whether it is the saddle guide rail 3 or the tailstock guide rail 5, the top surface of the guide rail has a certain inclination, that is to say, there is an angle between the top surface of the guide rail and the top surface of the base 1. Since the top surface of the guide rail is inclined Therefore, the slider at the bottom of the saddle assembly 8 slidably connected to the saddle guide rail 3 and the slider of the tailstock assembly 4 slidably connected to the tailstock guide rail 5 need to be designed to cooperate with the top surface of the guide rail. In this way, the production and processing of the slider is relatively harsh, and the production cost of the slider is relatively high, and it is troublesome to install the slider on the guide rail with an inclined top surface.
Moreover, the gravity on the saddle guide rail 3 and the tailstock guide rail 5 is also relatively large. Since the top surface of the guide rail is inclined, the force on the top of the guide rail is uneven, and the top surface of the guide rail is easily deformed, thereby making the service life of the guide rail longer. Shorter, affecting the accuracy of processing
[0005] In the same way, a pair of tailstock guide rails 5 on this type of numerically controlled machine tool is usually provided with high and low steps at present, that is, the height of the guide rail on the left side of the tailstock guide rail 5 is less than the height of the guide rail on the right side of the tailstock guide rail 5, and the difference between the two There is an angle between the plane formed between them and the top surface of the base 1, so that the gravity of the tailstock assembly 4 borne by the tailstock guide rail 5 is unstable, and the tailstock guide rail 5 is easily deformed, so that the service life of the tailstock guide rail 5 shortening will also affect the machining accuracy
[0006] In addition, the metal chips produced by the current processing are easy to accumulate at the root of the tailstock guide rail 5, and it is difficult to clean it. In addition, the accumulated debris also easily enters between the slide block of the tailstock assembly 4 and the tailstock guide rail 5. Occasionally affect the normal sliding of the tailstock assembly 4, affecting the machining accuracy

Embodiment 1

[0030] A special-purpose machine tool, comprising a base 1, an inclined bed 2, a tailstock guide rail 5, a saddle guide rail 3, a tailstock assembly 4 and a saddle assembly 8, the inclined bed 2 is fixed on the base 1 by screws, and the top of the base 1 It is a plane and parallel to the horizontal plane, and the base 1 is provided with a spindle assembly 7 . combine image 3 As shown, the saddle guide rail 3 is located on the inclined bed 2, the tailstock guide rail 5 is located on the base 1, and the top surface of the tailstock guide rail 5 and the top surface of the saddle guide rail 3 are parallel to the top surface of the base 1; The tops of the seat guide rails 5 are at the same height from the top of the base 1 , so the tops of the two tailstock guide rails 5 are on the same plane and parallel to the top surface of the base 1 . The saddle assembly 8 is slidably connected to the saddle guide rail 3, and the tailstock assembly 4 is slidably connected to the tailstock gu...

Embodiment 2

[0036] combine image 3 As shown, the cleaning assembly in this embodiment includes two sides of tailstock guide rail 5 Figure 4 The rotating disk 10 in the middle, the rotating disk 10 rolls on the base 1 along the length direction of the tailstock guide rail 5, a rotating shaft is connected between the two rotating disks 10, and the two ends of the rotating shaft pass through the rotating disk 10 and are welded on the rotating disk 10 On the inner wall far away from the tailstock guide rail 5, a bearing 19 is provided on the rotating shaft. Specifically, the bearing 19 is set in the middle of the rotating shaft, and the inner ring of the bearing 19 is welded to the rotating shaft; of course, the bearing 19 here can also be directly replaced by a sleeve Set on the sleeve on the shaft. combine Figure 5 As shown, the cleaning assembly also includes a driving block 20, the driving block 20 is slidably connected to the base 1 through the cooperation of the sliding groove and ...

Embodiment 3

[0043] In this embodiment, the rotating disk 10 is provided with several openings on the side away from the tailstock guide rail 5, and a cover is provided on the openings. When the iron filings in the cavity are almost collected, the cover can be taken out, the opening is opened, and the iron Chips are automatically discharged from the opening, thereby realizing the discharge of iron filings. Of course, the cavity is detachably connected with a magnet bar. If there is a groove on the inner wall of the cavity, insert the magnet bar in the groove, and the magnet bar can collect the iron filings in the cavity. When the iron filings are full, , open the cover, and take out the magnet bar from the opening, so as to realize taking out the iron filings from the cavity.

Description

technical field [0001] The invention relates to the field of numerical control machine tools, in particular to a special machine tool. Background technique [0002] CNC lathe is a high-precision, high-efficiency automatic machine tool. After the programmer compiles the program, it is input into the CNC computer system, and the drive system moves according to the program. The operator only needs to perform simple auxiliary operations. [0003] The CNC machine tool with inclined bed layout can not only reduce the floor area of ​​the machine tool under the same conditions; but also improve the rigidity of the bed through the overall closed cross-section design, especially without moving the workpiece, and can perform multi-angle, full-scale inspection of the workpiece. Azimuth for processing, the operation is more convenient. Therefore, CNC machine tools with inclined bed layout have been widely used in the lathe machining industry in recent years for the multi-variety process...
