It is mainly used for riveting of solid rivets, hollow rivets, and hollow rivets. It is widely used in the automotive manufacturing industry, electronic equipment manufacturing industry, machinery manufacturing industry, and construction industry. When producing and processing riveted nuts and studs, after tightening the nut on the stud, in order to further ensure the fastening between the nut and the stud, a riveting machine is required to press the tail of the riveted nut on the stud.

The riveting device includes an upper column, a lower column, a limit table located between the upper column and the lower column, and a first hydraulic cylinder that drives the upper column to move toward the lower column. The limit table is used to accommodate the steel plate. The top surface of the lower column is flush with the top surface of the limit table. The top surface of the lower column is provided with a mounting hole for accommodating rivets. The side of the lower column is provided with a feed channel connected to the mounting hole. The steel plate feeding device includes a conveyor belt for conveying steel plates and a second cylinder for pushing the steel plate on the conveyor belt toward the limit table. The rivet feeding device includes a vibrating plate feeder for conveying rivets, a third cylinder for pushing the rivets at the outlet of the vibrating plate feeder from the feed channel into the mounting hole, and a fourth hydraulic cylinder for lifting the rivets in the mounting hole upward. Therefore, automatic riveting of steel plates can be achieved, and the production efficiency of steel plate riveting can be improved.

[0004] However, in the above technical solution, when the tail of the rivet nut is riveted to the stud by using a riveting machine, the staff is first required to insert the rivet nut stud into a cavity formed by a number of rivet chucks, and then directly use the rivet chucks for riveting. As the staff work for a long time, the staff will inevitably become tired, causing the rivet nut to tilt when the staff inserts the rivet nut stud into the cavity formed by a number of rivet chucks, causing the rivet nut to tilt during the riveting process, resulting in riveting errors. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1 and Figure 2As shown, a riveting machine comprises a riveting machine body 1, a chuck mounting groove 2 is arranged on the riveting machine body 1, a plurality of riveting chucks 3 are arranged in the chuck mounting groove 2, a first groove 4 is arranged on one side of the chuck mounting groove 2, a limiting device 5 is arranged in the first groove 4, a fixed baffle 6 is arranged on the side of the chuck mounting groove 2 away from the limiting device 5, a lighting fixture 7 is arranged on one side of the riveting machine body 1, a material collecting frame 8 is arranged on the side below the lighting fixture 7, and a knob 9 is arranged on one side of the limiting device 5.

[0024] like Figure 3 and Figure 4 As shown, in another embodiment of the utility model, the position limiting device 5 includes a device base 501, a threaded hole 502 is provided on the device base 501, and a rotating threaded column 503 is provided in the threaded hole 502;

[0025] A slider 504 is disposed at one end of the rotating threaded column 503, and the slider 504 is slidably disposed in the first groove 4;

[0026] The slider 504 is provided with a second groove 505, a push plate 506 is slidably provided in the second groove 505, and a first sensor 507 is provided on a side of the push plate 506 close to the device base 501;

[0027] The inner wall of the second groove 505 near the device base 501 is provided with a second sensor 508 and a plurality of guide slots 509, in which a guide slide 5010 is slidably provided, and a spring 5011 is fixedly provided on the push plate 506. When it is necessary to press the rivet nut stud, the rotating threaded column 503 is first driven to rotate by the knob 9, and the position of the slider 504 is moved by rotating the threaded column 503 and the threaded hole 502, and then the position of the slider 504 is adjusted accordingly according to the tail length of the stud. After the adjustment is completed, the rivet nut stud is inserted into the cavity formed by the plurality of riveting chucks 3, and the tail of the stud is inserted into the second groove. The rear end of the stud is pressed against the second groove 505, and the rear end of the stud is pressed against the push plate 506, so that the push plate 506 moves toward the equipment base 501, and the push plate 506 drives the first sensor 507 to move, and the spring 5011 is deformed. When the first sensor 507 senses that it is in contact with the second sensor 508, the riveting chuck 3 moves toward the riveted nut stud, and the riveted nut stud is riveted, and the rear end of the riveted nut is riveted onto the stud. At this time, the rear end of the stud has entered the second groove 505. Therefore, during the riveting process, the rear end of the stud is fixed by the second groove 505, thereby fixing the entire riveted nut stud to prevent the riveted nut stud from tilting during the riveting process, resulting in riveting errors.

[0028] The working principle of this riveting machine:

[0029] When in use, first start the lighting fixture 7 to illuminate the pressure riveting chuck 3, then drive the rotating threaded column 503 to rotate through the knob 9, and move the position of the slider 504 by rotating the threaded column 503 and the threaded hole 502, and then adjust the position of the slider 504 accordingly according to the tail length of the stud. After the adjustment is completed, insert the riveted nut stud into the cavity formed by the plurality of pressure riveting chucks 3, and insert the tail of the stud into the second groove 505, and at the same time, the tail of the stud squeezes the push plate 506, so that the push plate 506 moves toward the equipment base 501, and the push plate 506 drives the first sensor 507 The spring 5011 is deformed, and when the first sensor 507 senses that it is in contact with the second sensor 508, the riveting chuck 3 moves toward the riveted nut stud, and rivets the riveted nut stud, and rivets the tail of the riveted nut onto the stud. At this time, the tail of the stud has entered the second groove 505. Therefore, during the riveting process, the tail of the stud is fixed by the second groove 505, thereby fixing the entire riveted nut stud. The riveted nut stud falls into the aggregate frame 8 under the action of gravity, which can effectively prevent the riveted nut stud from tilting during the riveting process, resulting in riveting errors.
