[0022] Compared with the prior art, the advantages of the present invention are:

[0023] 1. The present invention provides a riveting tool for floating panel screws, which solves the defect of the lack of such products on the market. Specifically, the riveting tool of the present application is connected to the lower die seat of the machine tool through a base assembly, and the upper rivet head is connected to the upper die seat of the machine tool to apply axial pressure to the rivet; the floating assembly is located between the base assembly and the upper rivet head, and the floating part of the floating assembly is used to place the washer, and can drive the washer to move downward, so that during the riveting process, the washer will not be squeezed and damaged by the upper rivet head, and the washer is effectively protected; the rod of the floating assembly is used to support the rivet and rivet the riveted part of the rivet, and the floating part is movably sleeved on the upper end outer surface of the rod, so as to achieve the purpose of the washer being movably sleeved on the outer surface of the riveted part; after the riveting is completed, the washer is sleeved on the deformed riveted part, and the edge of the deformed riveted part is bent and deformed in the direction of the washer and forms a vertical downward limit for the washer, so as to prevent the washer from detaching from the riveted part.

[0024] 2. An annular recess for placing the gasket is provided on the floating sleeve. During the riveting process, the gasket is restricted by the wall of the annular recess in the radial direction, and the stepped surface of the rivet squeezes the upper surface of the gasket, thereby making the gasket more firmly installed on the annular recess and not easy to fall off the floating sleeve.

[0025] 3. The upper end of the main connecting rod is a narrowed portion, and an annular groove is provided at the top of the narrowed portion. The groove wall of the annular groove can provide an upward supporting force for the lower end of the riveted portion. During riveting, the riveted portion is squeezed by the upper rivet head and the groove wall of the annular groove at the same time, and the lower end of the riveted portion enters the annular groove for shaping. Specifically, the lower end of the riveted portion gradually deforms along the shape of the annular groove, and the lower end of the riveted portion is restricted by the groove wall of the annular groove.

[0026] 4. A step is formed at the bottom end of the narrowed portion, and a first limiting distance is formed between the upper end surface of the step and the lower end surface of the floating sleeve, that is, the maximum distance that the upper rivet head can move downward after contacting the floating sleeve is the first limiting distance; it replaces the common riveting tools on the market that cannot control the degree of riveting and cannot limit the running distance of the upper rivet head; this solution limits the running distance of the upper rivet head through the upper end surface of the step and the lower end surface of the floating sleeve, and effectively avoids the situation where the upper rivet head moves too far downward, resulting in excessive deformation of the lower end of the riveted part, too thin thickness after deformation, and too low connection strength. This solution effectively controls the degree of riveting, reduces the situation of excessive riveting, and improves the qualified rate of product technology.

[0027] 5. A round hole is provided on the narrowed portion, and a long hole is provided on the floating sleeve. Pins are inserted through the round hole and the long hole at the same time, so that the maximum upward movement distance of the floating sleeve is limited, thereby preventing the floating sleeve from falling off from the upper end of the main connecting rod under the action of the elastic force of the return compression spring.

[0028] 6. A receiving groove is formed around the upper end of the mounting hole, and the receiving groove is used to clamp and fix a smaller connected part, or to install a protruding folded edge on a larger connected part.

[0029] 7. The present application also includes a fixing assembly for fixing the rivet head, the fixing assembly includes a cover plate and a plurality of fixing pins. After the cover plate is sleeved on the outer surface of the rivet head, the fixing pins are passed through the pin holes of the cover plate and inserted into the first blind holes of the main base, so that the cover plate and the main base are relatively fixed; on the one hand, the receiving hole of the cover plate fixes the rivet head in the radial direction to prevent the rivet from tilting during the riveting process, thereby avoiding the situation of poor riveting effect and uneven riveting shape; on the other hand, in the riveting direction, the plate body of the cover plate presses the connected part placed in the receiving groove, so that during the riveting process, the connected part is fixed more firmly on the riveting tooling.

[0030] 8. The present application also includes a limit assembly, which is a positioning pin. The positioning pin is inserted into the connected part and into the second blind hole of the main base, so that the connected part and the main base are relatively fixed, avoiding the connected part from shaking during the riveting process, thereby affecting the riveting process, or the connected part being squeezed and scratched by the upper rivet head.

[0044] Further references Figure 2 to Figure 4The rod portion is a main connecting rod 3, and the upper end of the main connecting rod 3 is a narrowing portion 302. The top of the narrowing portion 302 is provided with an annular groove 304, and the center of the annular groove 304 is on the axis of the narrowing portion 302. The groove wall of the annular groove 304 is bent in the direction in which the gasket 11 is set. The annular groove 304 is used to rivet the lower end of the riveted portion 171 and shape the riveted shape of the riveted portion 171; the floating portion is a floating sleeve 12, and the floating sleeve 12 is movably sleeved on the outer surface of the narrowing portion 302; the top of the floating sleeve 12 is formed with an annular recess 123 for placing the gasket 11, and the center of the annular recess 123 is on the axis of the through hole 121; the main connecting rod 3 is also provided with a convex edge 301, and the return compression spring 5 is sleeved on the main connecting rod 3, and one end of the return compression spring 5 abuts the convex edge 301, and the other end abuts the floating sleeve 12.

[0045] Specifically, the floating sleeve 12 is a cylindrical structure; the return compression spring 5 is a coil spring, which is sleeved on the main connecting rod 3, and the axis of the return compression spring 5 coincides with the axis of the main connecting rod 3; the convex edge 301 is a circular convex edge, which is integrally processed with the main connecting rod 3 and is located in the lower middle part of the main connecting rod 3.

[0046] Further references Figures 4 to 6 A step 303 is formed at the bottom end of the narrowing portion 302, and a first limiting distance is formed between the upper end surface of the step 303 and the lower end surface of the floating sleeve 12. The first limiting distance is defined according to the specific structure of the rivet or the specific degree of riveting. In this embodiment, the first limiting distance is 2 mm; a round hole is also provided on the narrowing portion 302, and a long hole 122 is provided on the floating sleeve 12. The length direction of the long hole 122 is consistent with the axial direction of the floating sleeve 12, and the pin 4 is simultaneously penetrated through the long hole 122 and the round hole.

[0047] Specifically, the upper end of the step 303 limits the excessive downward position of the floating sleeve 12; the cooperation of the pin 4 and the long hole 122 limits the excessive upward position of the floating sleeve 12, thereby preventing the floating sleeve 12 from excessively moving upward and thus detaching from the narrowing portion 302.

[0048] Further references Figure 4 The base assembly 14 includes a connecting base 1 and a main base 2. The connecting base 1 is arranged between the lower die base of the machine tool and the main base 2, and is detachably connected to the lower die base of the machine tool and the main base 2 respectively; the base assembly 14 forms a stepped hole, which is composed of a fixing hole 101 of the connecting base 1 and a mounting hole 201 of the main base 2.

[0049] Specifically, the connecting base 1 can be connected to the lower die base and the main base 2 of the machine tool by screws or bolts; the fixing hole 101 is a cylindrical hole, and the diameter of the fixing hole 101 is smaller than the diameter of the mounting hole 201. Due to the difference in the size of the apertures, a supporting surface is formed at the junction of the fixing hole 101 and the mounting hole 201, and the supporting surface is used to support the flange 301; the mounting hole 201 is also a cylindrical hole, and the diameter of the mounting hole 201 is equal to or slightly smaller than the outer diameter of the flange 301, and larger than the outer ring diameter of the reset compression spring 5.

[0051] Further references Figure 2 A receiving groove 204 is formed around the upper end of the mounting hole 201, one end of the mounting hole 201 is formed in the receiving groove (204), the receiving groove 204 is communicated with the mounting hole 201, and the receiving groove 204 is used to clamp and fix a smaller connected component.

[0052] Further references Figures 4 to 6 , and also includes a fixing component, which is detachably connected to the base component 14, and is used to fix the head 172 of the rivet 17 and the connected part.

[0053] Specifically, the fixing assembly includes a cover plate 7 and a plurality of fixing pins 10, and a plurality of pin holes 701 are provided on the cover plate 7; the main base 2 is provided with a plurality of first blind holes 202, and the fixing pins 10 are passed through the pin holes 701 and inserted into the first blind holes 202; the cover plate 7 is also provided with a receiving hole 702, and the receiving hole 702 is used to fix the head 172 of the rivet 17; on the one hand, the receiving hole 702 is sleeved on the outer surface of the head 172, so that the head 172 is fixed in the radial direction, avoiding the uneven riveting shape caused by the radial shaking of the head 172 during the riveting process; on the other hand, in the riveting direction, the plate body of the cover plate 7 presses the connected part placed in the receiving groove 204, so that during the riveting process, the connected part is fixed more firmly on the riveting tooling.

[0055] The riveting tool in the present solution can be used to perform riveting on various sheet metal parts. Here, the connected sheet metal part is taken as an example of a chassis door panel with a folded edge to demonstrate the use of the riveting tool; specifically, the folded edge 18 includes two lug structures, one of which is provided with a rivet hole, and the other is provided with a positioning hole.

[0056] When a chassis door panel with a folded edge needs to be riveted, the side wall of the door panel will interfere with the riveting tool. Therefore, in order to complete the riveting on the chassis door with a folded edge, you can only use a riveting fixture to crimp rivets on the unbent chassis door panel. After the riveting is completed, the edge of the chassis door panel is bent. In addition, during the bending process, it may cause problems such as scratching the rivets, which is very inconvenient.

[0057] Further references Figure 7 to Figure 10 The above-mentioned defects can be overcome by using the riveting tool in the present application. When riveting the chassis door panel with a folded edge, the riveting tool is placed on the side of the chassis door panel close to the folded edge 18, the connecting seat 1 is fixed to the lower die seat of the machine tool by screws, the upper rivet head 9 is installed on the die seat of the machine tool, and the axis of the upper rivet head 9 and the floating sleeve 12 are overlapped, the lug with the riveting hole is placed in the receiving groove 204, the washer 11 is placed on the annular concave platform 123, and the lower end of the riveted portion 171 is successively passed through The cover plate 7 is sleeved on the outer surface of the head 172 and the lug with the riveting hole is pressed and fixed. The fixing pin 10 is passed through the pin hole 701 and inserted into the first blind hole 202, so that the cover plate 7 is fixed relative to the main base 2. The positioning pin 6 is inserted into the second blind hole 203 through the positioning hole; the riveting machine is started, and the die base on the machine drives the riveting head 9 to press the rivet 17 downward, and the washer 11 is pressed by the stepped surface 173 of the rivet 17. The washer 11 is pressed downward, so that the floating sleeve 12 moves downward together, and the head 172 is pressed downward by the rivet head 9. When the spring inside the rivet 17 is compressed to the limit, the head 172 transmits the vertical downward extrusion force to the riveting part 171. The lower end of the riveting part 171 is guided and squeezed by the groove wall of the annular groove 304, so that it gradually bends and deforms along the groove wall shape of the annular groove 304. The deformed lower end edge of the riveting part 171 forms a limit to the excessive downward movement of the washer 11. After the riveting is completed, the fixing pin 10 is pulled out from the pin hole 701 and the first blind hole 202, the cover plate 7 is removed, and then the rivet 17 and the washer 11 are removed. The rest of the parts except for the rivet are removed. At this time, the diameter of the deformed portion at the lower end of the riveted portion 171 is larger than the inner diameter of the gasket 11, and the gasket 11 cannot be removed from the riveted portion 171. In addition, the outer diameter of the gasket 11 is larger than the diameter of the rivet hole. In this way, the rivet 17 is installed in the rivet hole through the gasket 11 and cannot be removed from the rivet hole. When the chassis door panel and other sheet metal parts are installed, they can be directly connected through the rivet 17 installed in the rivet hole.

[0058] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
