Description

Technical Field

[0001] The present application relates to the technical field of riveting machines, and in particular to an automatic riveting device. Background Art

[0002] In the field of machinery, when processing some rotating workpieces, it is often necessary to use dynamic balancing methods to counterweight the workpieces so that the workpieces can reach a balanced state when rotating at high speed, thereby improving the stability and efficiency of equipment operation.

[0003] There are three main methods for dynamic balancing verification currently available, namely, deweighting method, weighting method and adjustment method; the deweighting method is to remove part of the material on the heavier side of the workpiece by drilling, grinding, chiseling and laser perforating, so as to reduce the mass of that side and achieve balance; the weighting method is to add part of the weight on the lighter side of the workpiece by screw connection, riveting, welding, metal spraying and other methods to balance the mass on both sides of the workpiece; the adjustment method is to change the mass distribution of the workpiece by adjusting the position or number of correction blocks on the workpiece to achieve a balancing effect.

[0004] When using the weighting method to counterweight the workpiece, riveting is often used. First, place the workpiece on the workbench of the riveting machine, align the riveting head of the riveting machine with the position where riveting is required, and insert the rivet from top to bottom into the preset counterweight hole. The head of the rivet is against the top of the counterweight hole, and the tail of the rivet extends out of the lower end of the counterweight hole. The riveting head rivets the rivet from top to bottom, causing the rivet to deform, so that it fits tightly in the counterweight hole and forms a whole with the workpiece. During riveting, since the contact position between the riveting head and the rivet is the rivet head, the rivet head is often deformed, while the tail is still separated from the counterweight hole, and the quality of riveting is not high.

[0010] By adopting the above technical scheme, when the workpiece is riveted, the workpiece is first fixed on the top wall of the workbench, and the lateral adjustment component is adjusted. The lateral adjustment component drives the support component to move. The support component drives the upper pressure head and the lower pressure head to approach the workpiece to be riveted, and the rivet is placed on the counterweight hole of the workpiece to be riveted. Then the height adjustment component is adjusted so that the upper pressure head abuts against the head of the rivet to support the head of the rivet. Finally, the driving component is started, and the driving component drives the lower pressure head to approach the upper pressure head. The lower pressure head squeezes the tail of the rivet, so that the rivet is deformed in the counterweight hole, so that it is tightly embedded in the counterweight hole and forms a whole with the workpiece; an automatic riveting device is set, and the lower pressure head squeezes the rivet, which is convenient for avoiding deformation of the rivet head, thereby improving the riveting quality of the workpiece; at the same time, the lateral adjustment component and the height adjustment component are set, which are convenient for riveting workpieces of different heights and shapes, thereby improving the application range of the riveting press.

The upper support plate and the lower support plate are sleeved on the four guide columns. The upper support plate and the lower support plate slide along the length direction of the guide column. The upper support plate drives the upper pressure head to move, and the lower support plate drives the lower pressure head to move. It is convenient to adjust the riveting height according to workpieces of different heights, thereby improving the application range of the riveting press.

Since the piston rod is fixedly connected to the upper support plate, the upper support plate is supported and fixed by the second screw rod and the second screw rod nut, so that the piston rod pushes the hydraulic cylinder body upward in the opposite direction, and the hydraulic cylinder body drives the hydraulic cylinder mounting plate to move upward, the hydraulic cylinder mounting plate drives the four connecting rods to move upward, and the connecting rod drives the lower support plate to move upward along the length direction of the guide column, thereby making the lower pressure head fixedly connected on the lower support plate move upward, thereby realizing the riveting operation on the workpiece; the designed driving component drives the lower pressure head to rivet the workpiece, and the lower pressure head squeezes the tail of the rivet, so that the rivet is deformed in the counterweight hole, so that it is tightly embedded in the counterweight hole to form a whole with the workpiece, which is convenient for improving the riveting quality of the workpiece.

[0056] The implementation principle of an automatic riveting device in this embodiment is as follows: when riveting a workpiece, first the workpiece is fixedly placed on the top wall of the workbench 2, and the transverse driving motor 3423 is started. The transverse driving motor 3423 drives the first screw rod 3421 to rotate. When the first screw rod 3421 rotates, the first screw rod 3421 and the first screw rod 3421 nut produce relative rotation, and the first screw rod 3421 nut moves on the first screw rod 3421. Since the first screw rod 3421 nut is fixedly connected to the support plate 3411, the support plate 3411 moves along the length direction of the first screw rod 3421. At this time, the transverse sliding block 3413 fixedly connected to the support plate 3411 moves along the transverse guide The rail 3412 slides, the support plate 3411 drives the support assembly 33 to move, and the support assembly 33 drives the upper pressing head 31 and the lower pressing head 32 to approach the workpiece to be riveted, and places the rivet on the counterweight hole of the workpiece to be riveted; then the servo motor 351 is started, and the servo motor 351 drives the second screw rod 353 to rotate, and the second screw rod 353 and the second screw rod 353 nut produce relative rotation, so that the second screw rod 353 nut moves on the second screw rod 353, and the second screw rod 353 nut drives the upper support plate 331 to move along the length direction of the second screw rod 353, thereby causing the upper pressing head 31 to move, and the upper pressing head 31 abuts against the head of the rivet according to the position of the workpiece, 361, so that the piston rod 3612 and the hydraulic cylinder body 3611 produce relative movement, the piston rod 3612 extends out of the hydraulic cylinder body 3611, and pushes the upper support plate 331 downward. Since the piston rod 3612 is fixedly connected to the upper support plate 331, the upper support plate 331 is supported and fixed by the second screw rod 353 and the nut of the second screw rod 353, so that the piston rod 3612 pushes the hydraulic cylinder body 3611 upward in the opposite direction, and the hydraulic cylinder body 3611 drives the hydraulic cylinder mounting plate 362 to move upward, and the hydraulic cylinder mounting plate 362 drives the four connecting rods 363 to move upward, and the connecting rods 363 drive the lower support plate 332 along the length of the guide column 333. The rivet is moved upward in the degree direction, thereby causing the lower pressure head 32 fixedly connected on the lower support plate 332 to move upward and approach the upper pressure head 31. The lower pressure head 32 squeezes the tail of the rivet, causing the rivet to deform in the counterweight hole, thereby tightly fitting in the counterweight hole to form a whole with the workpiece, completing the riveting operation of the workpiece. After the riveting operation is completed, the hydraulic cylinder 361 is adjusted, the piston rod 3612 contracts, driving the hydraulic cylinder body 3611 to descend, causing the lower pressure head 32 to descend, and the servo motor 351 and the horizontal drive motor 3423 are reversed, so that the upper pressure head 31 and the lower pressure head 32 are away from the riveted workpiece, the riveted workpiece is removed, and the next workpiece is riveted.
