In the following description, numerous specific details are provided to provide a thorough understanding of embodiments of the invention. One skilled in the relevant art will recognize, however, that the inventive arrangements can be practiced without one or more of the specific details, or with other methods. In other instances, well-known methods, implementations, or operations are not shown or described in detail to avoid obscuring aspects of the invention.

The riveting device mainly comprises a control console with a service life monitor, a cylinder 1, a workpiece groove 5, a slide rail 7, a bearing component, a bottom support and the like.

Referring to fig. 1 to 4, the riveting device provided herein includes a cylinder 1, a bottom support plate 2, a workpiece groove 5, a slide rail 7, and a bearing assembly, wherein the slide rail 7 is mounted on the bottom support plate 2, and the workpiece groove 5 is mounted on the slide rail 7 and moves according to the path of the slide rail 7; the load bearing assembly is mounted above the workpiece channel 5 by means of guide rails 13.

The cylinder 1 is used for providing power to enable the workpiece groove 5 to slide on the sliding rail 7, and the bearing component moves along the guide rail 13 in the direction of the workpiece groove 5 under the action of force and is riveted with a product 6 to be riveted in the workpiece groove 5. The cylinder 1 comprises a bottom cylinder and a top cylinder, wherein the bottom cylinder provides power for the workpiece groove 5, and the top cylinder provides power for the bearing assembly.

The working principle of the riveting device provided by the invention is as follows: after the workpiece 6 to be riveted is placed in the workpiece groove 5, the starting button is pressed by two hands simultaneously to start the bottom cylinder to push the workpiece groove 5 to move towards the right lower part of the bearing component; when the workpiece groove 5 is positioned under the bearing component, the top cylinder is started to push the bearing component to move along the guide rail 13 to the direction of the workpiece groove 5 and rivet and press a product 6 to be riveted placed in the workpiece groove 5, and after the riveting and pressing are completed, the workpiece groove 5 returns to the initial position.

The bearing assembly mainly comprises five parts, namely a bearing disc 8, a bearing platform 9, a punch 10, a pre-clamping device 11, a longitudinal upper limiting column 12 and the like. Referring to fig. 1, 2 and 4, the bearing plate 8 fixes the bearing table 9, the punch 10, the pre-clamping device 11, and the longitudinal upper limiting column 12 according to the product size, and is stressed by the bearing table 9. When the riveting device starts to work, the workpiece groove 5 moves to the position right below the punch 10, the top air cylinder pushes the top piston to move downwards, the top piston is in contact with the bearing table 9 and continues to move downwards, and then the pre-clamping device 11 pre-clamps the product 6 to be riveted. And the top cylinder continues to push downwards until riveting is completed.

Wherein the inside expanding spring that has inlayed of clamping device 11 in advance, when riveting, the bearing dish pushes down, can carry out certain pre-clamping to the work piece through the spring reaction.

The vertical upper limit post 12 in the bearing assembly is used for limiting, when the bearing assembly slides downwards along the guide rail 13 under the action of the top cylinder, when a certain position is reached, the stroke of the top cylinder is limited when the vertical upper limit post 12 is contacted with the bottom support plate 2, the top cylinder stops pushing, and riveting is completed.

In this context, the bottom support plate 2 is provided with a lower longitudinal restraint post 4 which cooperates with an upper longitudinal restraint post 12. When the longitudinal upper limiting column 12 is contacted with the longitudinal lower limiting column 4, the stroke of the top cylinder is limited, and the pushing is stopped, so that the riveting is completed.

The longitudinal upper restraint posts 12 and the longitudinal lower restraint posts 4 are herein dimensioned according to circumstances.

In order to limit the workpiece groove 5 in the transverse direction, the riveting device further comprises a transverse limiting column 3. Can inject work piece groove 5 accurately in under the drift 10 through horizontal spacing post 3, by horizontal spacing post 3 restriction its stroke when work piece groove 5 slides under the drift 10, can't continue lateral shifting, can start the top cylinder at this moment and carry out the riveting.

Here the workpiece groove 5 is pre-loaded with a certain tolerance of the pre-loaded ball 51 at both ends, as shown in fig. 3. Through cooperating with the workpiece groove 5, can effectively adjust the tolerance when packing into and treating riveting product 6, guarantee the high accuracy of product riveting. The number of the movable balls 51 is determined according to the situation, and two, four or other movable balls may be used. The movable ball 51 is preassembled on two sides of the workpiece groove 5, the spring device is arranged below the movable ball 51, when the size of the riveting product 6 is out of tolerance, the movable ball 51 can stretch and move to absorb a certain tolerance, the riveting product 6 is locked, and the riveting product is prevented from moving in the riveting process.

In order to monitor the life of the punch 10, the punch 10 is connected to a control console with a life monitoring function, by means of which the service life of the punch 10 is monitored. The control console with the service life monitoring function monitors the service life of the punch through a PLC program and electric control, and the monitoring is not described too much here.

In order to realize that the top cylinder can automatically act when the workpiece groove 5 moves to the position below the punch 10, the top cylinder is controlled by a program, and the program starts the top cylinder to move downwards after the bottom workpiece groove moves to the limiting position for 2 seconds. And the top cylinder is positioned in a central console on the operating console and used for starting the top cylinder, and a simple industrial control program is not described in detail.

The riveting device provided by the invention can effectively ensure the riveting quality of the yoke through the limitation of the clamp and the system monitoring.

The riveting device provided by the invention is mainly used for riveting the U-shaped yoke of the ceramic high-voltage direct-current contactor, but can also be used for other riveting processes with the same riveting precision requirement, such as iron core riveting, structure riveting, component riveting and the like. The riveting size can be adjusted by only replacing the corresponding workpiece groove and adjusting the height of the limiting column according to the design requirement. Meanwhile, the workpiece groove can adopt a pre-installed movable ball to absorb corresponding product tolerance, so that the riveting consistency and reliability of the product are guaranteed.

The present disclosure has been described in terms of the above-described embodiments, which are merely exemplary of the implementations of the present disclosure. It must be noted that the disclosed embodiments do not limit the scope of the disclosure. Rather, variations and modifications are possible within the spirit and scope of the disclosure, and these are all within the scope of the disclosure.
