In the detailed description that follows, certain exemplary embodiments of the present invention are described by way of illustration only. It goes without saying that those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and are not intended to limit the scope of the claims.

[0021] like Figures 1 to 6As shown in the figure, the side operating cover transfer rod hole processing and fixing device comprises a horizontally arranged fixing base 1, a mounting plate 2 is extended upward from the middle of the fixing base 1, the cross section of the mounting plate 2 is in the shape of an "I", and a side operating cover mounting cavity is formed between the two side edges of the mounting plate 2 and its corresponding fixing base 1, and positioning and fixing devices are symmetrically arranged in the two side operating cover mounting cavities, the positioning and fixing devices comprise a positioning device for positioning the side operating cover and a fixing device for fixing the side operating cover, the positioning device comprises a plurality of positioning holes 3 arranged through the mounting plate 2, the positions of the positioning holes 3 correspond to the positions of the through holes on the side operating cover, a positioning column 4 is detachably installed in the positioning hole 3, the length of the positioning column 4 is greater than the thickness of the side operating cover, the outer diameter of the positioning column 4 is equal to the aperture of the through hole on the side operating cover, the fixing device comprises a stud fixedly mounted on the mounting plate 2, the screw A fixing plate is detachably mounted on the end of the column, and an elastic reset device is provided between the fixing plate and the mounting plate 2. The fixing device and the positioning device are opened, and the side operating cover to be punched is installed in the side operating cover mounting cavity. One side operating cover can be installed in each of the two side operating cover mounting cavities, and the holes are punched together, thereby improving processing efficiency. During installation, the through holes on the side operating cover are aligned with the positioning holes 3, and then the positioning posts 4 are inserted into any two of the positioning holes 3. The number of positioning holes 3 can be set to cope with different types of side operating covers. After the positioning posts 4 are inserted, the side operating cover is positioned on the mounting plate 2. At this time, the fixing plate is pressed against the side operating cover to complete the fixing of the side operating cover. The utility model not only accurately fixes the side operating cover on the mounting plate 2, but also allows two to be installed at the same time. The two side operating covers can simultaneously achieve the processing of the top transfer rod hole 16. The utility model can not only effectively and accurately fix the side operating cover, but also facilitates disassembly and installation, and can simultaneously process two workpieces, thereby improving processing efficiency.

[0022] like Figure 1 and Figure 5 As shown in the figure, the fixing device includes an upper fixing device and a lower fixing device. The upper fixing device is used to fix the upper portion of the side control cover, and the lower fixing device is used to fix the lower portion of the side control cover. Because the side control cover is a relatively tall plate-like structure, it is necessary to fix its upper and lower portions separately to ensure a more secure and precise operation.

[0023] like Figure 1As shown, the upper fixing device includes an upper stud 5 vertically mounted on the mounting plate 2. The end of the upper stud 5 is slidably mounted with an upper fixing plate 6. The outer side of the upper fixing plate 6 is removably fixed by an upper fastening nut 7. The upper fixing plate 6 is preferably a rectangular plate. When installing the side operation upper cover, the upper fixing plate 6 is first removed, the main through-hole of the side operation upper cover is passed through the upper stud 5, and the fixing plate is then fitted over the upper stud 5. The upper fastening nut 7 is then used to secure the upper fixing plate 6 tightly against the mounting plate 2.

[0024] like Figure 1 As shown, the elastic reset device is an upper reset spring 8 mounted on the upper stud 5 and located between the upper fixing plate 6 and the mounting plate 2. The upper reset spring 8 is used to automatically reset the upper fixing plate 6 when the upper cover is removed after machining.

[0025] like Figure 5 As shown, the position of the upper stud 5 corresponds to the position of the main through-hole in the side control cover, and the outer diameter of the upper return spring 8 is smaller than the inner diameter of the main through-hole in the side control cover. The upper return spring 8 is located in the main through-hole in the side control cover, and when it contracts, it does not interfere with the inner wall of the main through-hole.

[0026] like Figures 1 to 6 As shown together, the lower fixing device includes a first lower stud 9 and a second lower stud 10 vertically mounted on the mounting plate 2. The distance between the first lower stud 9 and the second lower stud 10 is greater than the width of the side operating cover. The end of the first lower stud 9 is slidably fitted with one end of a lower fixing plate 11. The outer side of the lower fixing plate 11 is blocked and fixed by a first lower fastening nut 12. A second lower fastening nut 13 is installed at the end of the second lower stud 10. The other end of the lower fixing plate 11 is provided with a notch 14, which overlaps the second lower stud 10 between the second lower fastening nut 13 and the mounting plate 2. When installing the side operating upper cover, first remove the upper fixing plate 6 and open the lower fixing plate 11. When opening the lower fixing plate 11, you only need to unscrew the first fastening nut and the second fastening nut first, then rotate the lower fixing plate 11 around the first lower stud 9 to disengage the notch 14 from the second lower stud 10, until it is rotated 90° to provide installation space for the side operating upper cover. At this time, place the side operating upper cover into the side operating upper cover installation cavity, align the through hole with the positioning hole 3 and insert the positioning column 4, then rotate the lower fixing plate 11 around the first lower stud 9 to hook the notch 14 on the second lower stud 10, then install the upper fixing plate 6, tighten the upper fastening nut 7, the first lower fastening nut 12 and the second lower fastening nut 13, and then complete the processing.

[0027] like Figures 1 to 6As shown in the figure, the elastic return device is a lower return spring 15 mounted on the first lower stud 9 and located between the lower fixing plate 11 and the mounting plate 2. The lower return spring 15 is used to automatically return to its original position when the first lower fastening nut 12 and the second lower fastening nut 13 are unscrewed when the side operation cover is removed after processing, and the lower return spring 15 will automatically return to its original position, popping the lower fixing plate 11 open for easy removal.
