firstly, the connecting plate 1 is inserted into the clamping grooves of the solar collector frames, the positions of the connecting plate 1 are adjusted, so that the center line of the connecting plate 1 is located above the splicing seams of the two adjacent solar collector frames 7, then the positioning plate 4 is clamped on the edges of the left side and the right side of the connecting plate 1 through the positioning boss 42, then the pressing plate 3 is moved towards the connecting plate 1 through the hydraulic riveting device, the elastic gaskets 5 are extruded to deform, the distance between the pressing plate 3 and the positioning plate 4 is reduced, the length of the punch 2 extending out of the second through holes 411 is increased, meanwhile, the heads of the bolts 6 are driven by the pressing plate 3 to move towards the connecting plate 1, at the moment, the length of the punch 2 extending out of the second through holes 411 is basically consistent and even in stress under the buffer effect of the elastic gaskets 5, so that the strength of the pressing plate 2 on the solar collector frames 7 is even finally, and the hydraulic riveting device can stop working on the aluminum profile 11 when the pressing plate 11 is stopped in the connecting plate 11.
The riveting tool for the solar collector frames in this embodiment inserts the connecting plate 1 into the clamping groove of the solar collector frames 7, and locates the center line of the connecting plate 1 above the splice seam of two adjacent solar collector frames 7, and locates the connecting plate by the locating plate 4, and the moving cooperation of the pressing plate 3 and the locating plate 4 in the punching process makes the punching head 2 punch the solar collector frames 7 into the grooves 11 of the connecting plate 1, so that the two adjacent solar collector frames 7 are riveted together, and the splicing of the two adjacent solar collector frames 7 is realized without adopting rivet riveting or pit pressing riveting or other modes, thereby effectively simplifying the splicing process of the solar collector frames 7, reducing the cost, and ensuring that the solar collector frames 7 have good appearance quality. In addition, through the cushioning effect of the elastic gasket 5, the stress of the solar collector frame 7 in the punching process of the punch head 2 is uniform, so that the riveting effect of the solar collector frame 7 and the connecting plate 1 is better.
Referring to fig. 12, in order to solve the same technical problem, the invention further provides a riveting method of a solar collector frame based on the riveting tool of the solar collector frame, which comprises the following steps:
s1, inserting the connecting plate 1 into a clamping groove of a frame 7 of the solar heat collector;
s2, adjusting the position of the connecting plate 1 to enable the middle part of the connecting plate 1 to be positioned above the splicing seams of two adjacent solar collector frames 7;
s3, adjusting the position of the punch 2, so that one end of the punch 2 away from the pressing plate 3 is positioned above the groove 11;
s4, opening the riveter, and enabling the riveter to push the punch 2 to perform punching work through the pressing plate 3;
s5, when the section bar at the clamping groove corresponding to the groove 11 of the solar heat collector frame 7 is stamped into the groove 11 of the connecting plate 1, the riveter is controlled to stop working.
According to the riveting method of the solar heat collector frames, the connecting plate 1 is inserted into the clamping grooves of the solar heat collector frames 7, then the positions of the connecting plate 1 are adjusted, the middle of the connecting plate 1 is located above the splicing seams of the two adjacent solar heat collector frames 7, the aluminum profiles at the clamping grooves of the solar heat collector frames 7 and the grooves 11 corresponding to the grooves 11 are punched into the grooves 11 of the connecting plate 1 through the punch heads 2, so that the two adjacent solar heat collector frames 7 are riveted together, splicing of the two adjacent solar heat collector frames 7 is achieved without adopting rivet riveting or pit pressing riveting and the like, the splicing process of the solar heat collector frames 7 is effectively simplified, the cost is reduced, and good appearance quality of the solar heat collector frames 7 is ensured.
The foregoing is merely a preferred embodiment of the present invention, and it should be noted that modifications and substitutions can be made by those skilled in the art without departing from the technical principles of the present invention, and these modifications and substitutions should also be considered as being within the scope of the present invention.
