[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention. Example

[0022] See also Figure 1-5 The utility model provides a technical solution: a guide rail obstacle clearing device, comprising a guide rail 1, a movable platform 2 is mounted on the guide rail 1, a lifting scraper 3 is provided on one side of the movable platform 2, and a boss 8 for clearing obstacles inside the groove is mounted on the bottom end of the lifting scraper 3;

[0023] A through slot 7 is provided on the lifting scraper 3, and a spacer sleeve 6 is slidably connected to the interior of the through slot 7. A spring 5 is installed between the spacer sleeve 6 and the inner wall of the through slot 7. When the movable platform 2 moves up and down, the lifting scraper 3 moves accordingly by compressing the spring 5, thereby avoiding interference.

[0024] A support plate 4 is provided on one side of the lifting scraper 3 , and a fixing bolt 9 for fixing the position of the lifting scraper 3 is installed on the support plate 4 .

[0025] like Figure 2 and Figure 5 As shown: a process groove for positioning the spring 5 is transversely opened at one end of the through slot 7; through the above arrangement, the spring 5 can be installed and fixed more conveniently and quickly.

[0026] like Figure 2 and Figure 3 As shown: the outer side of the spacer 6 is provided with a protrusion that is compatible with the end of the spring 5; through the above arrangement, the spring 5 can be quickly installed inside the through groove 7, so that the spacer 6 can slide more conveniently.

[0027] like Figure 4 As shown: the support plate 4 has a rectangular shape and is provided with screw holes; through the above arrangement, the support plate 4 can cover the through slot 7 and limit the internal spring 5.

[0028] like Figure 1 As shown: the cross section of the boss 8 is trapezoidal, and the boss 8 is clearance-matched with the groove of the guide rail 1; through the above arrangement, the debris inside the groove can be quickly pushed and cleaned.

[0029] like Figure 1 and Figure 3 As shown: the fixing bolt 9 passes through the interior of the spacer 6 and is connected to the movable platform 2; through the above arrangement, the position of the lifting scraper 3 can be restricted and fixed more conveniently and quickly, so that it can move up and down more quickly.

[0030] Working principle: This device is installed on the base of the movable platform 2. Under the action of the preload of the spring 5, the boss 8 at the lower end of the lifting scraper 3 fits into the guide rail groove. There is a small gap between the boss 8 and the guide rail groove, and the shoulder end face contacts the upper surface of the guide rail 1 through the preload of the spring 5. When the movable platform 2 moves horizontally, it clears the debris in the forward direction. When the movable platform 2 reaches the designated area, it drops onto the guide rail surface through the clamping and lifting mechanism. The movable platform 2 begins to bear the working load of the press. At this time, the lifting scraper 3 compresses the spring 5 and moves upward to meet the vertical displacement requirement. After the stamping work is completed, the movable platform 2 is lifted up, and the lifting scraper 3 is reset under the action of the spring 5, completing a working cycle.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
