[0038] See also Figure 1 , Figure 2 and Figure 3 A riveting jig 10 provided in one embodiment of the present application is used to form a product 20. The product 20 includes a shell 21 and a covering member 22. The shell 21 forms an edge under the action of pressure. The edge will cover a part of the covering member 22, so that the shell 21 is fixedly connected to the covering member 22 through the edge, that is, the shell 21 and the covering member 22 are tightly connected to form a whole through the edge. The riveting jig 10 includes a first fixing component 100, a second fixing component 200, a pushing member 300, a first buffer member 410 and a first elastic member 420. The second fixing component 200 is spaced apart from the first fixing component 100 and is used to carry the product 20; the pushing member 300 is slidably connected to the first fixing component 100, and the pushing member 300 can slide close to the first fixing component 100 to squeeze the product 20 to form an edge. The first buffer member 410 is slidably sleeved in the pushing member 300 and is used to abut against the product 20 . The first elastic member 420 abuts against the first buffer member 410 .

[0039] See also Figure 1 , Figure 2 and Figure 3In some embodiments, the first fixing assembly 100 includes a first fixing seat 110 and a first fastener 120. The first fixing seat 110 is provided with a sliding hole 111, and the pusher 300 is inserted into the sliding hole 111, so that the pusher 300 slides with the sliding hole 111, and then the pusher 300 slides close to or away from the second fixing assembly 200. The first fixing seat 110 may also be provided with a first fastening hole 112, and the extension direction of the sliding hole 111 is perpendicular to the extension direction of the first fastening hole 112, for example, the sliding hole 111 extends in a vertical direction, and the first fastening hole 112 extends in a horizontal direction, and the first fastening hole 112 and the sliding hole 111 are connected to each other. The first fastener 120 is inserted into the first fastening hole 112, so that the first fastener 120 can abut against the pusher 300, so that the pusher 300 can be temporarily fixed in the sliding hole 111. When the first fastener 120 abuts against different positions of the pusher 300 in the vertical direction, the relative position of the pusher 300 in the sliding hole 111 can be adjusted, that is, the distance between the pusher 300 and the second fixing assembly 200 can be adjusted. When the pusher 300 needs to slide relative to the sliding hole 111, the first fastener 120 can be pulled out of the first fastening hole 112 to achieve unloading of the first fastener 120 on the first fixing seat 110, so as to avoid the first fastener 120 generating a large friction resistance to the sliding of the pusher 300 and improve the smoothness of the sliding of the pusher 300 relative to the first fixing seat 110. The first fastener 120 can be a bolt or the like.

[0040] See also Figure 4 , Figure 5 and Figure 6 In some embodiments, a first sliding cavity 310 is provided in the pusher 300, a first buffer 410 is located in the first sliding cavity 310, and the first buffer 410 and the first sliding cavity 310 are slidably matched, and a first elastic member 420 is at least partially accommodated in the first sliding cavity 310, and the first elastic member 420 can be a spring or the like. The end of the first buffer 410 is used to abut against the product 20, and the first elastic member 420 abuts against the first buffer 410. The first elastic member 420 applies an elastic force to the first buffer 410, so that the first buffer 410 limits the position of the product 20 to limit the movement of the product 20, and prevents the product 20 from being deformed due to sliding or vibration, thereby improving the yield of the product 20. At the same time, the first elastic member 420 can absorb a large impact force, prevent a large external force from acting on the first buffer 410 to deform the product 20, and further improve the yield of the product 20.

[0041] See also Figure 5 , Figure 6 and Figure 7In some embodiments, the pusher 300 has an abutting surface 320, which is used to abut against the second fixing assembly 200. A receiving cavity 330 is formed on the abutting surface 320. The receiving cavity 330 is connected to the first sliding cavity 310. The receiving cavity 330 is used to receive the product 20. The bottom wall of the receiving cavity 330 forms a step surface 331, which is arranged around the first sliding cavity 310. The step surface 331 presses against the product 20 to form an edge of the product 20. It can be understood that the step surface 331 applies a pressing force to the product 20 in the vertical direction, and the side wall of the receiving cavity 330 applies a contact force to the product 20 in the horizontal direction. In this way, the receiving cavity 330 can play a good role in limiting the product 20 in the vertical and horizontal directions, preventing the product 20 from moving during the molding process, thereby improving the molding accuracy and yield of the product 20. The caliber of the receiving cavity 330 is larger than that of the first sliding cavity 310 , and the receiving cavity 330 and the first sliding cavity 310 are coaxially arranged, so that the step surface 331 is arranged around the first sliding cavity 310 .

[0042] See also Figure 1 , Figure 2 and Figure 3 In some embodiments, the second fixing assembly 200 includes a second fixing seat 210 and a support member 220, wherein the support member 220 is connected to the second fixing seat 210 and is used to support the product 20. The second fixing assembly 200 also includes a second fastener 230, wherein the second fixing seat 210 is provided with a mounting hole 211, wherein the support member 220 is inserted into the mounting hole 211, and the fixing seat is further provided with a second fastening hole 212, wherein the second fastening hole 212 is connected to the mounting hole 211, wherein the mounting hole 211 extends in a vertical direction, and the second fastening hole 212 extends in a horizontal direction, such that the extending directions of the mounting hole 211 and the second fastening hole 212 are perpendicular to each other. The second fastener 230 is inserted into the second fastening hole 212 and abuts against the support member 220, thereby achieving the fixing of the support member 220. When the second fastener 230 is pulled out of the second fastening hole 212 and separated from the second fixing seat 210, the support member 220 can be unloaded relative to the second fixing seat 210. Therefore, the second fastener 230 can realize a detachable connection relationship between the support member 220 and the second fixing seat 210. The second fastener 230 can be a bolt or the like.

[0043] In one embodiment, the support member 220 includes a support portion 221 and a boss portion 222. The support portion 221 has a limiting surface 2211. The limiting surface 2211 of the support portion 221 can abut against the abutting surface 320 of the push member 300. The limiting surface 2211 and the abutting surface 320 both extend in the horizontal direction, so the limiting surface 2211 and the abutting surface 320 are in contact with each other to generate a vertical abutting force. The boss portion 222 is protrudingly arranged on the limiting surface 2211. A sinking groove 223 is provided on one end of the boss portion 222 away from the limiting surface 2211. The sinking groove 223 is used to accommodate the product 20, so that the sinking groove 223 plays a good limiting role on the product 20, preventing the product 20 from moving, thereby preventing the product 20 from moving during the molding process, and ultimately improving the molding accuracy and yield. The product 20 is abutted between the boss portion 222 and the step surface 331 of the pusher 300 , so that the boss portion 222 and the step surface 331 apply a clamping force in the vertical direction to the product 20 , and finally the product 20 is hemmed.

[0044] See also Figure 5 , Figure 6 and Figure 7 For the riveting jig 10 with the support member 220, when working, the shell 21 of the product 20 is placed in the sink 223 of the support member 220, and the boss portion 222 bears the shell 21, and then the covering member 22 is placed on the shell 21. Then the pusher 300 is driven to move downward toward the support member 220, so that the step surface 331 of the support member 220 applies a resisting force to the edge of the shell 21. Under the limiting effect of the receiving cavity 330 of the pusher 300, the edge of the shell 21 will gradually bend and form an edge as the pusher 300 slides, so that the edge wraps the covering member 22, and finally the shell 21 is fixedly connected to the covering member 22 by riveting through the edge wrapping. During the process of the pusher 300 sliding to form the hemming, the first elastic member 420 applies elastic force to the first buffer member 410, the first buffer member 410 is sleeved outside the covering member 22, and the end of the first buffer member 410 generates a resisting force on the covering member 22 to limit the position of the product 20, thereby preventing the product 20 from being severely deformed such as concave, thereby improving the yield of the product 20. At the same time, the first elastic member 420 can absorb a large impact force, preventing a large external force from acting on the first buffer member 410 and causing deformation, thereby further improving the yield of the product 20.

[0045] See also Figure 8 , Fig. 9 and Fig.10In some embodiments, the support member 220 does not include the boss portion 222, that is, the support member 220 only includes the support portion 221, and the support portion 221 has a limiting surface 2211, which can abut against the abutting surface 320 of the pusher 300, and a recessed groove 223 is formed on the limiting surface 2211, and the recessed groove 223 is used to accommodate the product 20. For example, the shell 21 of the product 20 is accommodated in the recessed groove 223, and the recessed groove 223 has a good limiting effect on the product 20, preventing the product 20 from being deformed due to slippage, and improving the yield of the product 20.

[0046] See also Fig. 9 , Fig.10 and Fig.11 In some embodiments, the riveting jig 10 further includes a second buffer 510 and a second elastic member 520. A second sliding cavity 224 may be provided on the support portion 221 of the support member 220. The second sliding cavity 224 is communicated with the sink 223. The second buffer 510 slides with the second sliding cavity 224 and abuts against the product 20. The second elastic member 520 is at least partially accommodated in the second sliding cavity 224. The second elastic member 520 abuts against the second buffer 510. The second sliding cavity 224 is communicated with the sink 223. The caliber of the sink 223 may be larger than the caliber of the second sliding cavity 224. The second elastic member 520 applies an elastic force to the second buffer 510, so that the second buffer 510 limits the product 20 to prevent the product 20 from being severely deformed such as concave due to sliding or vibration, thereby improving the yield of the product 20. At the same time, the second elastic member 520 can absorb a large impact force, avoiding a large external force acting on the second buffer member 510 and deforming the product 20, further improving the yield of the product 20. The second elastic member 520 can be a spring or the like.

[0047] If the shell 21 and the covering part 22 are fixedly connected by bolt connection or welding, the manufacturing cost of the product 20 will increase due to the use of bolts and welding materials. If stamping is used to form the edging and the shell and the covering part 22 are connected by the edging, but the first buffer part 410 and the first elastic part 420 are not provided, the product 20 will be insufficiently positioned, and the product 20 will have serious deformation defects such as concave in the process of forming the edging, thereby affecting the manufacturing accuracy and yield of the product 20.

[0048] As for the riveting jig 10 in the above embodiment, the shell and the covering member 22 can be riveted together by hemming to form the product 20, thereby avoiding the use of bolts or welding materials, and ultimately reducing the manufacturing cost of the product 20. At the same time, the first buffer member 410 can position the product 20 to prevent the product 20 from being severely deformed such as concave, thereby improving the manufacturing accuracy and yield of the product 20, and the first elastic member 420 can absorb the impact energy acting on the product 20 through the first buffer member 410, avoiding the deformation of the product 20 due to a large impact force, and further improving the manufacturing accuracy and yield of the product 20.

[0049] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
