Description

Technical Field

[0001] The utility model belongs to the technical field of automation equipment, and particularly relates to an automatic rivet blind riveting equipment. Background Art

[0002] A blind rivet is a high-strength fastener for single-sided riveting. It is riveted by a special tool, a blind riveting gun, and is especially suitable for occasions where ordinary rivets are inconvenient to use. It has the characteristics of fast connection speed, convenience, and easy to purchase popularly, and is widely used in products such as buildings, automobiles, ships, airplanes, machines, electrical appliances, furniture, etc. It is often used especially in the riveting and maintenance of non-open parts of airplanes. Due to its unique structure and wide application scenarios, it plays an important role in industrial manufacturing and daily life;

[0003] The new energy battery box is an important part of the new energy vehicle battery pack, mainly carrying and protecting the power battery module. Among them, after the battery box is welded, when installing the cover on the battery box, blind rivets are required. As mentioned above, the use of blind rivets requires tools. Therefore, the current use method is often to manually hold a blind riveting gun for blind riveting operations. This is not only labor-consuming but also not suitable for automated assembly line production, with low efficiency. Therefore, to adapt to the rapidly developing society, an automatic rivet blind riveting equipment is needed to adapt to the fully automated production and processing environment.

[0004] Aiming at the problems raised in the above background art, the purpose of the utility model is to provide an automatic rivet blind riveting equipment.

[0005] To achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0006] An automatic rivet blind riveting equipment includes a multi-axis manipulator and a blind riveting gun. An installation plate is installed at the output end of the multi-axis manipulator. A lead screw is rotatably installed on the installation plate. The end of the lead screw is connected to a gear box. A motor is installed on the installation plate. The output end of the motor is connected to the power end of the gear box. A linear slide rail is provided on the installation plate. A slider is threadedly connected to the lead screw. The slider is slidably installed on the linear slide rail. An installation seat is installed on the slider. A sliding cylinder is provided on the installation seat. The blind riveting gun is slidably installed in the sliding cylinder. A bracket is installed on the installation seat. A telescopic cylinder is installed on the bracket. The output end of the telescopic cylinder is connected to the tail end of the blind riveting gun;

[0007] The slider is provided with a chute. An L-shaped pressing block is placed in the chute. A screw is threadedly connected to the slider. The end region of the screw is fixedly welded with a top plate. The end of the screw penetrates through the top plate. The L-shaped pressing block is provided with a through hole whose specification size matches the end of the screw.

[0008] Further limitation: The mounting base includes a bottom plate which is provided with fixing holes. The bottom plate is integrally connected with a support column, and the sliding cylinder is installed at the end of the support column. With such a design, the bottom plate can be firmly fixed on the slider through the fixing holes, thereby ensuring that the position of the output end of the rivet gun does not shift and guaranteeing the normal operation of the riveting.

[0009] Further limitation: The fixing holes are waist-shaped holes, and there are at least four fixing holes which are symmetrically arranged on both sides of the support column. With such a design, the setting of the waist-shaped holes enhances the adaptability of the installation, and the setting of the four fixing holes strengthens the fixing effect.

[0010] Further limitation: The L-shaped pressing block is provided with an inclined surface. With such a design, it can adapt to the fixing of mounting bases with different thicknesses.

[0011] Further limitation: The motor is a servo motor. With such a design, the servo motor can achieve very precise position, speed and torque control, usually with an accuracy in the micron or even nanometer level. It has a fast response speed to control signals, can quickly adjust the rotational speed and position, and can adapt to the requirements of high-speed movement and frequent start-stop. It has a stable output torque and rotational speed, is not easily affected by the working environment, and can still maintain stable performance during low-speed operation. There are multiple working modes to choose from, and the controller has flexible programming capabilities and supports multiple motion control modes.

The L-shaped pressing block 14 is provided with a through hole 17 with a specification size matching the end of the screw 15.

[0026] In this embodiment, when using an automatic rivet-pulling device, after the product that needs to perform the rivet-pulling action is transferred to the area to be riveted and fixed in position, the multi-axis manipulator 1 operates to drive the mounting plate 3 to move to the corresponding area. Then, the telescopic cylinder 12 operates to drive the rivet gun 2 to move towards the blind rivet under the limit of the sliding cylinder 10 and achieve cooperation with the blind rivet. Then, the rivet gun 2 operates to perform the rivet-pulling action on the blind rivet. After the rivet-pulling is completed, the telescopic cylinder 12 retracts the rivet gun 2 to a safe position, and the multi-axis manipulator 1 cooperates with the motor 6 to move the rivet gun 2 to another rivet-pulling position for work until all the rivet-pulling actions of the product are completed;

[0027] The operation of the motor 6, through the steering of the gearbox 5, causes the lead screw 4 to rotate, and then the slider 8 limited by the linear slide rail 7 can move in the axial direction of the lead screw 4. The movement of the slider 8 drives the mounting seat 9 to move, thereby achieving the purpose of moving the rivet gun 2 in the horizontal direction;

[0028] During the operation of the rivet gun 2, the pressure from the screw 15, the top plate 16 and the L-shaped pressing block 14 can ensure that the rivet gun 2 will not shift in position under the influence of the reaction force, ensuring the accuracy of automatic rivet-pulling.

[0029] Preferably, the mounting seat 9 includes a bottom plate 91. The bottom plate 91 is provided with fixing holes 92. The bottom plate 91 is integrally connected with a support column 93.

With such a design, the bottom plate 91 can be firmly fixed on the slider 8 through the fixing holes 92, thereby ensuring that the output end position of the rivet gun 2 does not shift and ensuring the normal operation of rivet-pulling. In fact, the structure of the mounting seat 9 can also be considered according to specific circumstances.

[0030] Preferably, the fixing holes 92 are waist-shaped holes, and there are at least four fixing holes 92, which are symmetrically distributed on both sides of the support column 93. With such a design, the setting of the waist-shaped holes 92 enhances the adaptability of the installation, and the setting of the four fixing holes 92 enhances the fixing effect. In fact, the structural style of the fixing holes 92 can also be considered according to specific circumstances.

[0031] Preferably, the L-shaped pressing block 14 is provided with an inclined surface 141. With such a design, it can adapt to the fixing of mounting seats with different thicknesses.

The precision is usually at the micron or even nanometer level. It has a fast response speed to control signals, can quickly adjust the rotational speed and position, and can meet the requirements of high-speed movement and frequent start-stop. It has stable output torque and rotational speed, is not easily affected by the working environment, and can still maintain stable performance during low-speed operation. There are multiple working modes to choose from, and the controller has flexible programming capabilities and supports multiple motion control modes. In fact, the selection of the motor 6 can also be considered according to specific circumstances.

[0033] The above embodiments only exemplarily illustrate the principles and effects of the present invention, rather than limiting the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention.
