DETAILED DESCRIPTION
[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0023] like Figures 1 to 4 As shown, a riveting press positioning device described in an embodiment of the utility model comprises a processing table 1; a plurality of electric cylinders 12 are fixedly connected to the top of the processing table 1 in a circumferential manner; a push block 13 is fixedly connected to the output end of the electric cylinder 12; a fixing rod 14 is fixedly connected to the top of the push block 13; a mounting block 15 is slidably connected to the middle of the fixing rod 14; a retaining assembly 20 is installed in the middle of the mounting block 15; a slot 16 is provided on the side of the mounting block 15 away from the electric cylinder 12; a push plate 17 is slidably connected to the middle of the slot 16; when working, a corresponding number of mounting blocks 15 are sleeved on the middle of the fixing rod 14 according to the specifications of the multi-layer workpiece to be riveted, and The position of the mounting block 15 is adjusted through the retaining component 20, and then the multi-layer workpiece is placed in turn above the processing table 1 near the middle position, and then the multiple electric cylinders 12 are started to push the multiple push blocks 13 to move toward the center position. During the movement, the multi-layer workpiece will be squeezed by the push plate 17, the mounting block 15 or the fixing rod 14, so that it is fixed in the middle. At the same time, some smaller-sized workpieces will be positioned between the two layers of larger-sized workpieces after being squeezed by the push plate 17, so that the multi-layer workpiece can be positioned and then riveted. Through the above structure, when the multi-layer workpiece is riveted, the smaller part of the workpiece can be positioned, thereby improving the accuracy of riveting.
[0024] like Figures 1 to 4As shown, the retaining assembly 20 includes a first slot 2; the first slot 2 is opened inside the mounting block 15; a sliding rod 21 is slidably connected to the middle part of the first slot 2; a top plate 22 is fixedly connected to the side of the sliding rod 21 facing the fixing rod 14; a first bolt 23 is threadedly connected to the middle part of the side wall of the mounting block 15; the first bolt 23 is arranged at one end of the sliding rod 21 away from the top plate 22; during operation, after the mounting block 15 is slidably mounted on the middle part of the fixing rod 14, the position of the mounting block 15 in the middle part of the fixing rod 14 is adjusted so that the push plate 17 can be flush with the smaller workpiece during processing, and then the first bolt 23 is rotated to make the first bolt 23 squeeze the sliding rod 21, so that the top plate 22 squeezes the fixing rod 14, and the friction between the top plate 22 and the fixing rod 14 is increased, so that the mounting block 15 will not easily slide in the middle part of the fixing rod 14. Through the above structure, the height of the mounting block 15 can be conveniently adjusted, so that the push plate 17 can more accurately push the smaller workpiece between the multi-layer workpieces.
[0025] like Figures 1 to 3 As shown, the top of the push plate 17 is slidably connected with an extension plate 3; a second groove 31 is opened in the middle of the extension plate 3; the top of the push plate 17 is threadedly connected with a second bolt 32; the second bolt 32 is located inside the second groove 31; when working, the second groove 31 can be slid out from the inside of the extension plate 3 according to the difference in specific sizes of the workpieces, and then the second bolt 32 is rotated to fix the position of the extension plate 3, so that the contact time between the four sides of the same workpiece and multiple extension plates 3 is different, thereby moving the workpiece to a position off-center. At the same time, the existence of the extension plate 3 can adjust the position of workpieces of different sizes, thereby increasing the scope of application of the lifting device.
[0026] like Figures 1 to 3 As shown, the end of the extension plate 3 away from the push plate 17 is symmetrically arranged and fixed with a pair of spring plates 4; the side wall of the spring plate 4 is fixed with a fixed plate 41; during operation, when the workpiece squeezed in the middle by multiple push plates 17 is a circular workpiece, the setting of the fixed plate 41 reduces the occurrence of riveting position deviation caused by the circular workpiece rolling along the end of the push plate 17.
[0027] like Figures 1 to 4 As shown, the push plate 17 can be replaced or maintained by sliding it out from the inside of the slot 16. After the push plate 17 is slid into the inside of the slot 16, the end of the limiting plate 5 will limit the end of the slot 16 under the pull of the elastic rope 51, thereby reducing the push plate 17 from sliding out of the slot 16 due to equipment vibration.
[0028] like Figure 1 to Figure 2As shown, a plurality of third grooves 6 are provided on the top of the push block 13; the depth of the plurality of third grooves 6 is less than the length of the push plate 17; when it is not necessary to use more push plates 17 to position the workpiece, the excess push plates 17 can be placed inside the third grooves 6, so that they can be conveniently taken out when needed, and the occurrence of loss of the push plates 17 is reduced.
[0029] like Figure 4 As shown, a rubber pad 7 is fixedly connected to the side of the top plate 22 facing the fixed rod 14; the position where the fixed rod 14 contacts the rubber pad 7 is set in a plane; through the above structure, the contact area and friction between the top plate 22 and the fixed rod 14 can be increased, thereby reducing the occurrence of the mounting block 15 sliding easily in the middle of the fixed rod 14.
[0030] During operation, a corresponding number of mounting blocks 15 are sleeved on the middle of the fixing rod 14 according to the specifications of the multi-layer workpiece to be riveted, and the position of the mounting block 15 is adjusted by the retaining assembly 20, and then the multi-layer workpiece is placed in sequence above the processing table 1 near the middle position, and then multiple electric cylinders 12 are started to push multiple push blocks 13 to move toward the center position. During the movement, the multi-layer workpiece will be squeezed by the push plate 17, the mounting block 15 or the fixing rod 14, so that it is fixed in the middle. At the same time, some smaller-sized workpieces will be positioned between two layers of larger-sized workpieces after being squeezed by the push plate 17, so that the multi-layer workpiece can be positioned and then riveted. After the mounting block 15 is slidably installed in the middle of the fixing rod 14, the position of the mounting block 15 in the middle of the fixing rod 14 is adjusted so that the push plate 17 can be flush with the smaller-sized workpiece during processing, and then the first bolt 23 is turned. The first bolt 23 squeezes the sliding rod 21, so that the top plate 22 squeezes the fixing rod 14, and the friction between the top plate 22 and the fixing rod 14 is increased, so that the mounting block 15 will not easily slide in the middle of the fixing rod 14. The second slot 31 can be slid out from the inside of the extension plate 3 according to the difference in the specific size of the workpiece, and then the second bolt 32 is rotated to fix the position of the extension plate 3, so that the contact time of the four sides of the same workpiece with multiple extension plates 3 is different, thereby moving the workpiece to a position off-center, and the push plate 17 can be replaced or maintained by sliding it out of the inside of the slot 16. After the push plate 17 is slid into the inside of the slot 16, the end of the limit plate 5 will limit the end of the slot 16 under the pull of the elastic rope 51. When it is not necessary to use more push plates 17 to position the workpiece, the excess push plates 17 can be placed in the inside of the third slot 6.
