Technical Field

[0001] This utility model relates to the field of aluminum product processing, and in particular to an aluminum shell rivet installation mechanism. Background Technology

[0002] Rivets are an important component for riveting parts to ensure structural stability without affecting use. A rivet is a nail-shaped object used to connect two parts (or components) with through holes and a cap at one end. In the process of aluminum product processing, it may be necessary to rivet aluminum shells. This requires drilling mounting holes on the two aluminum shells that need to be fixed, then passing the rivet through the mounting holes and pressing the capless end of the rivet to achieve riveting.

[0003] A search revealed Chinese Patent Publication No. CN222288696U, which discloses a rivet installation mechanism, comprising: a material platform, a feeding component, and an installation component. The material platform holds the parts to be connected, the feeding component delivers the rivets to the mounting holes of the parts to be connected, and the installation component drives the rivets into the mounting holes to rivet the parts to be connected.

[0004] To facilitate the rivet passing through the mounting hole, the mounting hole is usually slightly larger than the rivet, resulting in a gap between the rivet and the mounting hole, which may affect the connection and fixation effect. Utility Model Content

An auxiliary mechanism is located above the pressure plate, including a mounting plate mounted on top of the pressure plate via a guide assembly. The mounting plate slides up and down, and a pressure rod is fixedly connected to the bottom of the mounting plate. The pressure rod is coaxially arranged with the placement groove. A receiving hole communicating with the forming groove is located on the top of the pressure plate, and a portion of the pressure rod is located within the receiving hole. A spring is fixedly connected between the mounting plate and the pressure plate, and the spring is wound around the outer periphery of the pressure rod. The auxiliary mechanism also includes a power assembly for driving the mounting plate to move downward.

[0008] Preferably, the power assembly includes a mounting bracket fixedly connected to the top of the pressure plate, a rotary motor fixedly connected to the rear side of the mounting bracket, a rotary shaft connected to the output end of the rotary motor via a coupling, the rotary shaft being rotatably connected between the front and rear inner walls of the mounting bracket, and a cam fixedly connected to the rotary shaft, the cam being located above the mounting plate.

[0009] Preferably, the corners on both sides of the top wall of the mounting plate are rounded.

[0010] Preferably, the guide assembly includes two guide rods fixedly connected to the top of the pressure plate, a mounting plate slidably connected to the guide rods, and a limit block fixedly connected to the top of the guide rods, the limit block being located above the mounting plate.

[0026] like Figures 1-5 As shown, an aluminum shell rivet installation mechanism includes a workbench 1. The top of the workbench 1 has a placement groove 101. The height of the placement groove 101 is the same as the thickness of the existing cap of the rivet. The rivet is placed upside down in the placement groove 101 with the tip facing upward. The mounting holes on the two parts to be fixed both pass through the rivet.

[0027] An extrusion mechanism is provided above the workbench 1. The extrusion mechanism includes a pressure plate 203. A forming groove 204 is provided at the bottom of the pressure plate 203. The forming groove 204 is an arc-shaped groove to avoid the rivet edges being too sharp after extrusion. The extrusion mechanism also includes a frame 201 fixedly connected to the top of the workbench 1. The frame 201 is an inverted L-shape. Two sets of symmetrically arranged hydraulic cylinders 202 are fixedly connected to the frame 201. The pressure plate 203 is fixedly connected to the bottom of the hydraulic cylinders 202.

[0028] An auxiliary mechanism is provided above the pressure plate 203. The auxiliary mechanism includes a mounting plate 301. The mounting plate 301 is mounted on the top of the pressure plate 203 via a guide assembly. The guide assembly includes two guide rods 304 fixedly connected to the top of the pressure plate 203. The mounting plate 301 is slidably connected to the guide rods 304. A limit block 305 is fixedly connected to the top of the guide rods 304. The limit block 305 is located above the mounting plate 301.

[0029] The mounting plate 301 slides up and down. A pressure rod 302 is fixedly connected to the bottom of the mounting plate 301. The bottom end of the pressure rod 302 is conical. The pressure rod 302 is coaxially arranged with the placement groove 101. The top of the pressure plate 203 has a receiving hole that communicates with the forming groove 204. A part of the pressure rod 302 is located in the receiving hole. A spring 303 for resetting is fixedly connected between the mounting plate 301 and the pressure plate 203. The spring 303 is wrapped around the outer periphery of the pressure rod 302.

[0030] The auxiliary mechanism also includes a power assembly for driving the mounting plate 301 to move downwards. The power assembly includes a mounting bracket 401 bolted to the top of the pressure plate 203. The mounting bracket 401 is U-shaped with its opening facing downwards. A rotary motor 402 is bolted to the rear side of the mounting bracket 401. The output end of the rotary motor 402 is connected to a rotating shaft 403 via a coupling. The rotating shaft 403 is rotatably connected between the front and rear inner walls of the mounting bracket 401. A cam 404 is fixedly connected to the rotating shaft 403. The cam 404 is located above the mounting plate 301. The corners on both sides of the top wall of the mounting plate 301 are rounded to improve the stability of the cam 404 when it moves relative to the mounting plate 301.

[0031] Working principle: In use, first place the rivet upside down in the placement slot 101 with the headless end facing upwards. Then, pass the rivet through the mounting holes on the two parts to be fixed. Control the hydraulic cylinder 202 to move the pressure plate 203 downwards. The forming groove 204 flattens the tip of the rivet, making the end of the rivet arc-shaped. When the rivet is compressed to a certain extent, start the rotary motor 402. The rotary motor 402 drives the rotary shaft 403 to rotate the cam 404. The tip of the cam 404 rotates downwards. The cam 404 drives the mounting plate 301 to slide downwards along the guide rod 304. The mounting plate 301 drives the pressure rod 302 to move downwards. The pressure rod 302 compresses the rivet, causing the side wall of the rivet to extend and deform outwards, improving the tight fit between the rivet and the mounting hole of the workpiece, and improving the installation and fixing effect. After the tip of the cam 404 rotates away, the mounting plate 301 moves upwards and resets under the action of the spring 303.
