Description

Technical Field

[0001] This utility model relates to the field of automotive steering wheel frame die casting manufacturing technology, specifically a steering wheel horn reverse cone contact rivet pressing tool. Background Technology

[0002] During the die-casting process of automotive steering wheel frames, rivets are used to connect the steering wheel contacts to the frame. The riveting force is significant, requiring high hardness in the tapered rivet joints. These joints are prone to wear during use and need periodic replacement. If the tapered riveting is too shallow, the required force may not be sufficient; if it is too deep, the rivet risks cracking.

[0003] However, in actual use, the existing equipment often uses a press head to directly press the rivet into the rivet hole of the steering wheel frame from the front. Since the tail of the rivet is exposed on the product surface after it is pressed in, it is easy to be bumped during internal process turnover and finished product transportation, which may cause the rivet to loosen or even fall out of the product. In view of this, we propose a steering wheel horn reverse cone contact rivet pressing tool. Utility Model Content

[0004] The purpose of this invention is to provide a tooling for pressing the reverse conical contact rivets of a steering wheel horn, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a steering wheel horn reverse cone contact rivet pressing fixture, comprising a base, a slide rod fixedly connected to the outer wall of the base, a fixing plate fixedly connected to the upper outer wall of the slide rod, a pressure rod fixedly connected to the upper outer wall of the fixing plate, the output end of the pressure rod penetrating the fixing plate and fixedly connected to a pressure plate, a riveting assembly fixedly connected to the lower outer wall of the pressure plate, and a fixing assembly provided inside the base, the fixing assembly comprising:

[0006] The slot is formed on the outer wall of the base, the inner wall of the slot is fixedly connected with a tapered rivet head, the inner wall of the slot is fixedly connected with a protrusion, and the inner wall of the slot is engaged with a steering wheel frame.

[0007] The mounting slot is formed on the outer wall of the steering wheel frame, the inner wall of the mounting slot is provided with contact points, and the inner wall of the mounting slot is provided with rivet holes.

[0008] Preferably, the base has a stabilizing component inside, which includes a slot on the upper outer wall of the base. A plug is slidably connected to the inner wall of the slot. A spring is fixedly connected to the lower outer wall of the plug. A retaining plate is fixedly connected to the upper outer wall of the plug. A groove is formed on the upper outer wall of the plug. A rod is fixedly connected to the lower outer wall of the pressure plate. When the pressure rod pushes the pressure plate down to rivet the contact point with the riveting component, the steering wheel frame can be fixed by the rod.

[0009] Preferably, the groove and the insert rod are located on the same vertical line perpendicular to the base, the diameter of the groove is the same as the diameter of the insert rod, and the insert rod is engaged with the groove. When the pressure plate moves down, the insert rod is inserted into the groove and engaged with the groove, so that the insert rod can stably drive the insert block to move in the slot, making it difficult for the insert rod to come loose from the groove.

[0010] Preferably, the end of the spring away from the insert block is fixedly connected to the inner wall of the slot, and the end of the clamping plate away from the insert block is in contact with the steering wheel frame. When the insert block is under pressure, it can drive the clamping plate to move down and press against the steering wheel frame, making the steering wheel frame difficult to move. When the insert block loses pressure, the spring drives the insert block to reset, causing the clamping plate to leave the steering wheel frame.

[0011] Preferably, the number of tapered rivet heads, the number of riveting components, and the number of mounting slots are all set to four sets. The four sets of tapered rivet heads are respectively fixedly connected to the inner wall of the slot below a set of mounting slots, so that the tooling can rivet four sets of contacts on the steering wheel frame at one time.

[0012] Preferably, the inner wall of the mounting groove is provided with a through riveting hole. The riveting hole of the mounting groove, the riveting hole of the contact point and the conical riveting head are located on the same line. When the riveting assembly is pressed, the conical riveting head can form a conical indentation on the tail of the rivet, causing the inside of the rivet column to expand and bulge, forming an inverted structure in the rivet hole, thereby avoiding loosening caused by rivet collision and vibration.

[0013] Preferably, the outer wall of the pressure plate has a through groove that matches the slide rod. The slide rod passes through and is fixedly connected to the inner wall of the groove, so that the pressure plate can move down stably, thereby enabling the riveting assembly to better align with the riveting hole.

[0014] Compared with the prior art, this utility model provides a steering wheel horn reverse cone contact rivet pressing tool, which has the following beneficial effects:

[0015] 1. This steering wheel horn reverse conical contact rivet crimping fixture can form a conical indentation on the tail of the rivet during crimping using a conical rivet head. This causes the rivet post to expand and bulge inside, forming an inverted structure in the rivet hole. This avoids loosening caused by rivet collision and vibration, improves production efficiency, improves product quality, reduces scrap rate, and provides convenience for mass production.

[0016] 2. This steering wheel horn-shaped reverse cone contact rivet crimping fixture uses a rod inserted into a groove to engage with it. This allows the rod to stably move the insert block within the slot, causing the clamping plate to move downwards and press against the steering wheel frame, preventing it from moving easily. When the insert block loses pressure, a spring drives it to reset, causing the clamping plate to disengage from the steering wheel frame, allowing the steering wheel frame to be removed. This fixture secures the steering wheel frame during riveting without hindering its removal after riveting. Attached Figure Description

Detailed Implementation

[0022] like Figures 1-4 As shown, this utility model provides a technical solution: a steering wheel horn reverse conical contact rivet pressing fixture, including a base 1, a slide rod 2 fixedly connected to the outer wall of the base 1, a fixing plate 3 fixedly connected to the upper outer wall of the slide rod 2, a pressure rod 4 fixedly connected to the upper outer wall of the fixing plate 3, the output end of the pressure rod 4 passing through the fixing plate 3 and fixedly connected to a pressure plate 5, a riveting assembly 6 fixedly connected to the lower outer wall of the pressure plate 5, and a fixing assembly 7 provided inside the base 1, the fixing assembly 7 including a slot 71, a conical rivet head 72, a protrusion 73, a steering wheel frame 74, a mounting groove 75, a contact point 76, and a rivet hole 77.

[0023] In one embodiment of this utility model, a slot 71 is formed on the outer wall of the base 1, a conical rivet head 72 is fixedly connected to the inner wall of the slot 71, a protrusion 73 is fixedly connected to the inner wall of the slot 71, and a steering wheel frame 74 is engaged with the inner wall of the slot 71.

[0024] In one embodiment of the present invention, the mounting groove 75 is formed on the outer wall of the steering wheel frame 74, the inner wall of the mounting groove 75 is provided with contact points 76, and the inner wall of the mounting groove 75 is provided with riveting holes 77.

[0025] In addition, a stabilizing component 8 is provided inside the base 1. The stabilizing component 8 includes a slot 81, which is opened on the upper outer wall of the base 1. A plug 82 is slidably connected to the inner wall of the slot 81. A spring 83 is fixedly connected to the lower outer wall of the plug 82. A retaining plate 84 is fixedly connected to the upper outer wall of the plug 82. A groove 85 is opened on the upper outer wall of the plug 82. A plug rod 86 is fixedly connected to the lower outer wall of the pressure plate 5. When the pressure rod 4 pushes the pressure plate 5 down to rivet the contact 76, the plug rod 86 can fix the steering wheel frame 74, so that the riveting component 6 can more accurately rivet the contact 76 and the steering wheel frame 74, preventing the contact 76 and the steering wheel frame 74 from being misaligned during riveting.

[0026] In this embodiment of the utility model, the groove 85 and the insert rod 86 are located on the same vertical line perpendicular to the base 1. The diameter of the groove 85 is the same as the diameter of the insert rod 86. The insert rod 86 is engaged with the groove 85. When the pressure plate 5 moves down, the insert rod 86 is inserted into the groove 85 and engaged with the groove 85, so that the insert rod 86 can stably drive the insert block 82 to move in the slot 81, making it difficult for the insert rod 86 to come loose from the groove 85, and so that the clamping plate 84 can stably fix the steering wheel frame 74.

[0027] In this embodiment of the invention, the end of the spring 83 away from the insert block 82 is fixedly connected to the inner wall of the slot 81, and the end of the retaining plate 84 away from the insert block 82 contacts the steering wheel frame 74. When the insert block 82 is under pressure, it can drive the retaining plate 84 to move down and press against the steering wheel frame 74, making the steering wheel frame 74 difficult to move. When the insert block 82 loses pressure, the spring 83 drives the insert block 82 to reset, causing the retaining plate 84 to leave the steering wheel frame 74, so that the steering wheel frame 74 can be removed.

[0028] In the embodiments of this utility model, four sets of tapered rivet heads 72, four sets of riveting components 6, and four sets of mounting slots 75 are provided. The four sets of tapered rivet heads 72 are respectively fixedly connected to the inner wall of the slot 71 below the mounting slot 75, so that the tooling can rivet four sets of contacts 76 on the steering wheel frame 74 at one time, making the riveting speed of the tooling faster and more efficient.

[0029] In an embodiment of this utility model, a through riveting hole 77 is provided on the inner wall of the mounting groove 75. The riveting hole 77 of the mounting groove 75, the riveting hole 77 of the contact 76, and the conical riveting head 72 are located on the same line. When the riveting assembly 6 is riveted, the conical riveting head 72 can form a conical imprint on the tail of the rivet during the riveting process, causing the inside of the rivet post to expand and bulge, forming an inverted structure in the rivet hole. This avoids loosening caused by rivet collision and vibration, and makes the riveting stability of the contact 76 and the steering wheel frame 74 higher.

[0030] In an embodiment of this utility model, the outer wall of the pressure plate 5 is provided with a through groove that matches the slide rod 2. The slide rod 2 passes through and is fixedly connected to the inner wall of the groove, so that the pressure plate 5 can move down stably, thereby enabling the riveting assembly 6 to better align with the riveting hole 77, and thus enabling the tooling to more stably rivet and fix the contact point 76 to the steering wheel frame 74.

[0031] In this utility model, during use, the pressure rod 4 pushes the pressure plate 5 downward, causing the insertion rod 86 to insert into the groove 85 and engage with it. This allows the insertion rod 86 to stably drive the insertion block 82 to move within the slot 81, and the insertion rod 86 to drive the clamping plate 84 downward to press down on the steering wheel frame 74, making the steering wheel frame 74 less prone to movement. This allows the riveting assembly 6 to more accurately rivet the contact point 76 to the steering wheel frame 74, preventing misalignment between the contact point 76 and the steering wheel frame 74 during riveting. At this time, the riveting assembly 6 is aligned with the riveting hole 77. When the riveting assembly 6 presses down... During riveting, the tapered riveting head 72 can form a tapered indentation on the tail of the rivet during pressing, causing the rivet post to expand and bulge inside, forming an inverted structure in the rivet hole. This avoids loosening caused by rivet collision and vibration, improves production efficiency, reduces the frequency of rework by operators, ensures product quality, reduces scrap rate, and provides convenience for mass production. After installation, the pressure rod 4 moves the pressure plate 5 upward. When the insert block 82 loses pressure, the spring 83 drives the insert block 82 to reset, causing the retaining plate 84 to leave the steering wheel frame 74, so that the steering wheel frame 74 can be removed.

[0032] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
