[0029] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the accompanying drawings. The accompanying drawings show preferred embodiments of the present invention.

[0030] like Figure 1 and Figure 2 As shown, a precision riveting device 10 with position detection includes a loading assembly 100 and a riveting assembly 200. The loading assembly 100 includes a bottom plate 110, a loading seat 120, an elastic member 130, a rivet pin 140, a limit seat 150 and a displacement sensor 160. The rivet pin 140 is arranged on the bottom plate 110, the loading seat 120 is sleeved outside the rivet pin 140 along the vertical direction, the elastic member 130 is arranged between the loading seat 120 and the bottom plate 110, and the elastic member 130 is respectively in contact with the loading seat 120 and the bottom plate 110, the limit seat 150 is arranged on the bottom plate 110 with an adjustable height, and the displacement sensor 160 is arranged on the bottom plate 110. The device 160 is arranged on the loading seat 120, and the detection end of the displacement sensor 160 is arranged toward the bottom plate 110. The riveting assembly 200 includes a riveting plate 210, a riveting head 220 and a limiting column 230. The riveting head 220 and the limiting column 230 are both arranged on the riveting plate 210, and the riveting head 220 is aligned with the loading seat 120, and the limiting column 230 is aligned with the limiting seat 150. The riveting plate 210 is used to descend so that the riveting head 220 drives the copper column 22 and the rivet needle 140 to rivet, so that the limiting column 230 abuts against the limiting seat 150, and the detection end of the displacement sensor 160 abuts against the bottom plate 110.

[0031] It should be noted that the precision riveting device 10 with position detection of the present application is used to be installed on the riveting machine platform. Specifically, the loading assembly 100 is used to be installed on the table of the riveting machine, and the riveting assembly 200 is used to be installed on the power arm of the riveting machine. The power arm of the hydraulic press drives the riveting assembly 200 to move up and down. Further, the bottom plate 110 is used to be fixedly installed on the machine platform of the riveting machine, and the loading seat 120 is slidably installed on the bottom plate 110 along the vertical direction, that is, the loading seat 120 can slide close to or away from the bottom plate 110. The elastic member 130 is respectively in contact with the loading seat 120 and the bottom plate 110. For example, the elastic member 130 is also a spring. In this way, under the elastic thrust of the elastic member 130, the loading seat 120 has a tendency to move away from the bottom plate 110 in a natural state. One end of the rivet pin 140 is fixedly installed on the bottom plate 110, and the other end of the rivet pin 140 is inserted into the loading seat 120. In this way, when a pressing force is applied to the carrier seat 120, the carrier seat 120 descends close to the bottom plate 110, so that the rivet needle 140 extends from the center position of the carrier seat 120. The limit seat 150 is installed on the bottom plate 110, and the limit seat 150 is distributed adjacent to the carrier seat 120. The displacement sensor 160 is installed on the carrier seat 120. When the carrier seat 120 is forced to descend, the displacement sensor 160 follows the descent and makes its detection end abut against the bottom plate 110. In this way, the descent distance of the carrier seat 120 can be accurately controlled by the reading of the displacement sensor 160. Furthermore, the riveting plate 210 is used to be fixedly installed on the power arm of the riveting press, and the power arm of the hydraulic press drives the riveting plate 210 to perform lifting and lowering movements. The riveting head 220 is installed on the riveting plate 210, and the riveting head 220 is aligned with the carrier seat 120. The limiting column 230 is also installed on the riveting plate 210, and the limiting column 230 is aligned with the limiting seat 150. In this way, when the clamping ring 24 is placed in the material carrier 120, and then the rubber sleeve 21 is placed in the material carrier 120, and then the spring 23 and the copper column 22 are placed in the rubber sleeve 21 in sequence, as the riveting plate 210 descends, the riveting head 220 pushes the copper column 22 to compress the spring 23. When the spring 23 is compressed to the limit position, the riveting head 220 pushes the rubber sleeve 21, and the rubber sleeve 21 pushes the material carrier 120 to descend, and the elastic member 130 is compressed, so that the copper column 22 approaches and is finally riveted by the rivet needle 140. At the same time as the riveting is completed, the limiting column 230 abuts against the limiting seat 150, and the detection end of the displacement sensor 160 abuts against the bottom plate 110. In this way, by adjusting the height of the limit seat 150 relative to the base plate 110, the specific descending height of the rivet head 220 can be adjusted, so that the copper column 22 is riveted into the required size. After the riveting size of the copper column 22 is set, by setting a value that meets the tolerance requirements for the displacement sensor 160, each riveted buffer 20 can be actually monitored. Specifically, when the rivet head 220 descends for riveting, once the displacement sensor 160 sends a signal that the descent distance does not meet the standard, it means that the copper column 22 is not riveted into place.In this way, the position detection of each buffer 20 is achieved, thereby effectively improving the riveting quality of the product.

[0032] like Figure 1 and Figure 2 As shown, in one embodiment, the loading assembly 100 also includes a transfer seat 170, a sliding cavity 171 is opened on the transfer seat 170, one end of the rivet pin 140 is arranged on the inner bottom wall of the sliding cavity 171, the loading seat 120 is slidably arranged in the sliding cavity 171, and the elastic member 130 is respectively abutted against the inner bottom wall of the sliding cavity 171 and the loading seat 120.

[0033] It should be noted that, due to the diversity of models of the buffer 20, the structures of different models are different, especially the external structure of the rubber sleeve 21 is not consistent. In order to be able to perform riveting processing on buffers 20 of different models, a transfer seat 170 is provided. Specifically, a sliding cavity 171 is provided in the transfer seat 170, and the rivet pin 140 is fixedly installed on the inner bottom wall of the sliding cavity 171, and the material carrier 120 is slidably installed in the sliding cavity 171, so that the transfer seat 170, the rivet pin 140, the elastic member 130, and the material carrier 120 form a whole, wherein the transfer seat 170 is a detachable structure relative to the bottom plate 110, so that the transfer seat 170, the rivet pin 140, the elastic member 130, and the material carrier 120 can be quickly replaced according to different shapes of the buffer 20.

[0034] like Figure 2 As shown, in one embodiment, a positioning step 172 is provided at the opening of the sliding cavity 171, and the positioning step 172 is engaged with the material carrier 120. Thus, the material carrier 120 is clamped by the positioning step 172 to prevent the material carrier 120 from sliding out of the sliding cavity 171.

[0035] like Figures 1 to 3 As shown, in one embodiment, the loading assembly 100 also includes a support seat 180 and a clamping member 190. The support seat 180 is disposed on the base plate 110. A receiving groove for accommodating the transfer seat 170 is opened in the support seat 180. The clamping member 190 is disposed on one side of the support seat 180, and the clamping member 190 is used to clamp the transfer seat 170.

[0036] It should be noted that the above structure is provided in order to enable rapid replacement of the transfer seat 170. Specifically, the support seat 180 is mounted on the bottom plate 110, and a receiving groove is provided on the support seat 180, so that the transfer seat 170 can be adaptively installed in the receiving groove. The clamping member 190 is mounted on one side of the support seat 180, and the transfer seat 170 is clamped and fixed by the clamping member 190.

[0037] like Figure 3As shown, in one embodiment, the locking component 190 includes a locking block 191, a locking pin 192 and a locking spring 193. The locking block 191 is set on the outer wall of the support seat 180. The locking pin 192 passes through the locking block 191 and the support seat 180 in sequence. The locking spring 193 is respectively in contact with the locking pin 192 and the locking block 191. The locking spring 193 is used to push the locking pin 192 so that one end of the locking pin 192 clamps the transfer seat 170.

[0038] Thus, in a natural state, the locking spring 193 pushes the locking pin 192, so that one end of the locking pin 192 is clamped and fixed to the transfer seat 170. When the transfer seat 170 needs to be removed, it is only necessary to apply a pulling force in the opposite direction to the locking pin 192 to compress the locking spring 193, so that the locking pin 192 will be away from the transfer seat 170, and the transfer seat 170 can be taken out of the support seat 180.

[0039] like Figure 2 and Figure 3 As shown, in one embodiment, a locking groove 173 is provided on the outer wall of the transfer seat 170, and one end of the locking pin 192 is used to be inserted into the locking groove 173. In this way, the locking pin 192 is inserted into the locking groove 173, so that the transfer seat 170 can be clamped in the support seat 180. In one embodiment, a plurality of locking grooves 173 are provided, and intervals are provided between each of the locking grooves 173.

[0040] like Figure 1 and Figure 2 As shown, in one embodiment, the limit seat 150 includes a seat sleeve 151, an adjusting nut 152 and a top column 153. The seat sleeve 151 is set on the support seat 180, the top column 153 is screwed into the seat sleeve 151, the adjusting nut 152 is screwed on the outer wall of the top column 153, and the adjusting nut 152 is abutted against the seat sleeve 151.

[0041] It should be noted that the seat cover 151 is mounted on the support seat 180 by screws, a threaded hole is provided on the seat cover 151, the top column 153 is screwed into the threaded hole, the adjusting nut 152 is screwed onto the top column 153, and the adjusting nut 152 is in contact with the seat cover 151. In this way, after the top column 153 is rotated to a desired height position, the adjusting nut 152 is rotated to be pressed against the seat cover 151, so that the height position of the top column 153 remains unchanged.

[0042] like Figure 1 As shown, in one embodiment, the precision riveting device 10 with position detection further includes a guide sleeve 310 and a guide column 320 , wherein the guide sleeve 310 is disposed on the support seat 180 , one end of the guide column 320 is disposed on the riveting plate 210 , and the other end of the guide column 320 is passed through the guide sleeve 310 .

[0043] It should be noted that in order to ensure that the riveting head 220 accurately rivets the buffer 20 in the carrier 120 , a guide structure of the guide column 320 cooperating with the guide sleeve 310 is provided.

[0044] Furthermore, in one embodiment, two guide sleeves 310 are provided, and the two guide sleeves 310 are respectively located on both sides of the intermediate transfer seat 170. In this way, the riveting accuracy of the riveting head 220 can be improved.

[0045] In one embodiment, the end of the rivet pin 140 is configured as a conical structure. Thus, when one end of the copper column 22 contacts the end of the rivet pin 140, since one end of the copper column 22 is a cylindrical structure, one end of the copper column 22 is stretched open by the rivet pin 140 to form a trumpet shape, so that one end of the copper column 22 is clamped by the clamp ring 24.

[0046] like Figure 4 FIG. 1 is a schematic diagram of the structure of the precision riveting device 10 with position detection of the present application applied to a hydraulic press, wherein the material loading assembly 100 is installed on the machine table of the hydraulic press, and the riveting assembly 200 is installed on the power arm of the hydraulic press.

[0047] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
