Description

Technical Field

[0001] The utility model relates to a pressure riveting device, in particular to a pressure riveting detection device. Background Art

[0002] The riveting process is a fast and efficient connection method, especially suitable for sheet metal connections in mass production environments. It can quickly and firmly press fasteners such as rivets or nuts into pre-punched holes to form a reliable connection. Riveting causes metal to undergo plastic deformation through pressure, which does not affect the physical properties of the material itself or damage the surface of the parts. It has high connection strength and is widely used in the connection and assembly of thin plates or sheet metal parts in various industrial manufacturing fields.

[0003] During the riveting process, due to unskilled operation or lack of concentration of workers, some parts that need to be riveted may be skipped on the production line. Especially on automatic batch production lines, the robot or feeding system is prone to malfunction, resulting in rivets or nuts not being accurately placed in place, resulting in missing rivets, affecting the overall quality and reliability of the product, and causing the product to fail to meet design requirements and relevant standards.

The second workbench is provided with a second press groove, the bottom surface of the second press groove is provided with a second sensing device, and the second sensing device is arranged in a through hole provided in the bottom surface of the second press groove. A positioning column is provided on the top surface of the press table, and riveting nut sensing devices are provided on both sides of the press table, and the riveting nut sensing devices are connected to the press table through a first connecting plate. During the riveting operation, bottom holes are pre-punched at both ends of the parts, and the riveting nut is placed on the upper side of the press table and sleeved on the outer side of the positioning column. The riveting nut sensing device senses that the riveting nut has been sleeved into the positioning column and sends a signal. Then put the part to be riveted into the first pressing groove. At this time, the pre-punched bottom hole at one end of the part is coaxial with the positioning column. The first sensing device senses that the part is placed in the first pressing groove, and the first sensing device sends a signal. The riveting machine receives the signals of the rivet nut sensing device and the first sensing device, and the riveting machine performs riveting operations on one end of the part.

The first sensing device and the second sensing device use photoelectric sensors.

[0007] Furthermore, in the above-mentioned riveting detection device, the first pressing groove includes a first groove and a second groove, the extension line of the center line of the first groove intersects with the positioning column, and the center line of the first groove and the center line of the second groove form an angle. The first pressing groove is set according to the shape of the part to be riveted, and the extension line of the center line of the first groove intersects with the positioning column, so that when the part to be riveted is placed in the first pressing groove, the pre-punched hole at one end of the part to be riveted is coaxial with the positioning column, reducing the difficulty of positioning for workers and improving the riveting efficiency. In addition, the first groove and the second groove form an angle to limit the part to be riveted to avoid movement during the riveting process.

[0008] Furthermore, in the above-mentioned riveting detection device, the second pressing groove includes a third groove and a fourth groove.
