Description
Technical Field
[0001] The present invention relates to the technical field of correcting the arc portion of a shrapnel, and in particular to a correcting device for precisely correcting the arc portion of a shrapnel. Background Art
[0002] The structure of the shrapnel produced by a certain workshop is as Figures 1 to 2 shown. It includes a thin plate 1, two through holes 2 are opened on the top surface of the thin plate 1, a bent plate 3 is connected to the left end of the thin plate 1, an arc portion 4 is connected to the right end of the thin plate 1, and an outer hook portion 5 is connected to the end portion of the arc portion 4. The bent plate 3, the thin plate 1, the arc portion 4 and the outer hook portion 5 are integrally formed.
[0003] After a batch of shrapnels as Figures 1 to 2 shown are produced by the mold, the radian of the arc portion 4 does not meet the design requirements [possibly due to problems with the mold forming process]. For this reason, workers need to correct the arc portion 4 of the shrapnel so that the radian of the arc portion 4 meets the design requirements.
[0004] In the workshop, the method for workers to correct the arc portion 4 of the shrapnel is as follows: Workers take out a shrapnel, then use a clamp to tightly fix the thin plate 1 of the shrapnel, then use pliers to clamp the outer hook portion 5, and then pull the outer hook portion 5 to gradually increase the radian of the arc portion 4, thereby realizing the correction of the arc portion 4 of the first shrapnel; Workers repeat the above operations continuously to correct the arc portions 4 of multiple shrapnels.
[0005] However, although the method of using pliers to pull the outer hook portion 5 can correct the arc portion 4, in actual operation, the following technical defects are still reflected; If the pulling force of the pliers is too large, the radian of the arc portion 4 becomes larger, and the radian of the arc portion 4 does not meet the design requirements, thereby reducing the correction quality of the arc portion 4 of the shrapnel, and there is a technical defect of low correction accuracy. If the pulling force of the pliers is too small, the radian of the arc portion 4 is not corrected in place, and the correction quality of the arc portion 4 of the shrapnel is also reduced, and there is a technical defect of low correction accuracy.
[0006] Therefore, there is an urgent need for a correcting device that can greatly improve the correction quality of the arc portion of the shrapnel and has high correction accuracy. Summary of the Invention

[0019] The movable block 13 and the push plate 15 are integrally formed. The left end face of the push plate 15 is flush with the left end face of the movable block 13. A threaded hole 9 is formed in the movable block 13. The threaded hole 9 of the movable block 13 is threadedly connected to the adjusting screw 12.
[0020] The working method of the present invention is as follows: S1. Positioning of the elastic sheet. The specific operation steps are as follows: S11. The worker takes out an elastic sheet to be corrected as shown in the figure, embeds the arc portion 4 of the elastic sheet from front to back onto the extension plate 8 of the base 6, and places the thin plate 1 of the elastic sheet flat on the top surface of the base 6; Figures 1 to 2 S12. The worker moves the elastic sheet back and forth until the two through holes 2 on the elastic sheet are respectively communicated with the two pin holes 10 on the base 6; S13. The worker takes out two pin shafts, the worker passes the pin shafts 21 through the through holes 2 of the elastic sheet from top to bottom, and inserts the lower ends of the pin shafts 21 into the pin holes 10, so as to position the elastic sheet on the base 6. As shown in the figure, at this time, the outer hook portion 5 of the elastic sheet and the push plate 15 on the movable block 13 are opposite to each other left and right; S13. The worker takes out two pin shafts, the worker passes the pin shafts 21 through the through holes 2 of the elastic sheet from top to bottom, and inserts the lower ends of the pin shafts 21 into the pin holes 10, so as to position the elastic sheet on the base 6. As shown in the figure, at this time, the outer hook portion 5 of the elastic sheet and the push plate 15 on the movable block 13 are opposite to each other left and right; Figures 10 to 11 S2. The worker sleeves the two light holes 11 of the pressing block 16 of the pressing assembly respectively on the two pin shafts 21, and supports the pressing block 16 on the top surface of the thin plate 1 of the elastic sheet. Then, the locking screw 22 penetrates through the pressing block 16 and is threadedly connected to the threaded hole 9 on the base 6 to fix the pressing block 16 on the base 6, so as to fix the elastic sheet between the base 6 and the pressing block 16. At this time, the connection portion between the arc portion 4 and the thin plate 1 is just fixed between the outer arc surface of the extension plate 8 and the inner arc surface 20 of the convex block 19, as shown in the figure. S2. The worker sleeves the two light holes 11 of the pressing block 16 of the pressing assembly respectively on the two pin shafts 21, and supports the pressing block 16 on the top surface of the thin plate 1 of the elastic sheet. Then, the locking screw 22 penetrates through the pressing block 16 and is threadedly connected to the threaded hole 9 on the base 6 to fix the pressing block 16 on the base 6, so as to fix the elastic sheet between the base 6 and the pressing block 16. At this time, the connection portion between the arc portion 4 and the thin plate 1 is just fixed between the outer arc surface of the extension plate 8 and the inner arc surface 20 of the convex block 19, as shown in the figure. Figures 12 to 13As shown, at the same time, both of the two limit blocks 18 on the pressing component are located on the right side of the movable block 13; S3. The worker rotates the adjusting screw 12, and the movable block 13 moves to the right along the length direction of the adjusting screw 12. The movable block 13 drives the push plate 15 to move to the right synchronously. The push plate 15 gradually presses the outer hook portion 5 of the elastic piece to the right, thereby gradually increasing the radian of the arc portion 4 of the elastic piece. When the movable block 13 is blocked by the limit block 18, the correction of the arc portion 4 of the first elastic piece is finally realized. At this time, the radian of the arc portion 4 of the elastic piece is exactly the same as the designed angle; S4. The worker repeats the operations of steps S1 to S3 multiple times, and the arc portions 4 of multiple elastic pieces can be continuously corrected.
[0021] Among them, in step S1, the elastic piece is positioned on the base 6 through the pin shaft 21; in step S2, the pressing block 16 is fixed on the base through the locking screw 22, so that the connection between the arc portion 4 and the thin plate 1 is just fixed between the outer arc surface of the extension plate 8 and the inner arc surface 20 of the convex block 19; in step S3, by rotating the adjusting screw 12, the movable block 13 moves to the right along the adjusting screw 12, and the push plate 15 gradually presses the outer hook portion 5 of the elastic piece to the right, thereby gradually increasing the radian of the arc portion 4 of the elastic piece. When the movable block 13 is blocked by the limit block 18, the correction of the arc portion 4 of the elastic piece is finally realized.
[0022] It can be seen from this that the moving distance of the movable block 13 is determined by the limit block 18, and the corresponding moving distance of the push plate 15 is fixed and unchanged. Therefore, the push plate 15 can push the outer hook portion 5 to the specified position to the right, and further correct the radian of the arc portion 4 of the elastic piece to the designed radian. Therefore, compared with the method of the worker using tweezers to pull the outer hook portion 5 to correct the arc portion, this correction device greatly improves the correction quality of the arc portion 4 of the elastic piece and has the characteristics of high correction accuracy.
