Referring to fig. 8 to 9, in an embodiment, the first roller cutter assembly 300 includes a first bolt 370 and a second flange 380, the first bolt 370 is mounted on a bearing through the second flange 380, and when the drive plate 520 drives the bearing to rotate, the first bolt 370 does not rotate. With continued reference to fig. 8 to 9, the fixing member 610 may include a fixing block 611 and a second bolt 612, the fixing block 611 is fixedly mounted on the table 110, the second screw is mounted on the fixing block 611, the first bolt 370 and the second bolt 612 are respectively connected by an elastic member, the first hob assembly 300 is pulled toward the fixing member 610, so that the bearing abuts against the abutting surface 520a of the driving plate 520.

Those skilled in the art can understand that the specific structure of the second hob assembly 400 can refer to the specific structure of the first hob assembly 300, and has the beneficial effects brought by the technical solutions of the corresponding embodiments, which are not described in detail herein. It is understood that the second roller cutter assembly 400 may also be constructed differently than the first roller cutter assembly 300.

The above description is only an alternative embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.

Claims

1. An automatic roll riveting device is characterized by comprising:

a machine table having a table top;

the rotary jig is arranged on the table board and used for pressing a product and driving the product to rotate, and the rotation axis of the product extends along the vertical direction;

the first hob assembly and the second hob assembly are both arranged on the table board and can be close to and far away from the rotary jig so as to roll and rivet the product clamped on the rotary jig for forming;

the first hob assembly and the second hob assembly are arranged oppositely.

2. The automatic roll riveting device according to claim 1, further comprising a driving assembly mounted on the machine table, wherein the driving assembly comprises a cylinder body and a driving plate mounted on the cylinder body, and the driving plate is provided with an abutting surface abutting against the first hob assembly, so that the driving plate pushes the first hob assembly to approach the rotating jig.

3. The automatic roll riveting apparatus according to claim 2, further comprising a reset assembly, wherein the reset assembly comprises a fixed member and an elastic member mounted on the table, one end of the elastic member is connected to the fixed member, and the other end of the elastic member is connected to the first rolling cutter assembly, so that the first rolling cutter assembly abuts against the abutting surface.

4. The automatic roll riveting apparatus of claim 3, wherein the abutment surface is provided as a curved surface, and the width of the drive plate in a direction approaching the first rolling cutter assembly gradually decreases.

5. The automatic roll riveting apparatus of claim 3, further comprising an adjustment assembly mounted to the table top, the adjustment assembly comprising a stop member, the stop member being adjustable in distance from the drive plate, the stop member being adapted to abut the drive plate to limit continued proximity of the drive plate to the first rolling cutter assembly.

6. The automatic roll riveting apparatus of claim 5, wherein the adjustment assembly further comprises a base, the base is mounted to the table, the blocking member is mounted to the base, and the position between the blocking member and the base is adjustable to adjust the distance between the blocking member and the drive plate; and/or the presence of a gas in the gas,

the blocking member is mounted with a buffer.

7. The automatic roll riveting apparatus of claim 6, wherein the adjustment assembly further comprises a first fastener, the stop member having a first guide aperture, the first guide aperture extending in a direction toward and away from the drive plate, the first fastener being slidable within the first guide aperture, the first fastener passing through the first guide aperture to couple with the base.

8. The automatic roll riveting apparatus of claim 6, wherein the base is adjustable in position on the table top to adjust the distance of the stop on the base from the drive plate.

9. The automatic roll riveting device according to any one of claims 2 to 8, wherein the first hob assembly comprises a fixed seat, a first hob, a slide block and a slide rail mounted on the table top, the first hob is mounted on the fixed seat, the slide block is mounted at the bottom of the fixed seat, and the slide block is slidable on the slide rail; the fixed seat is abutted against the abutting surface or an abutting part abutted against the abutting surface is arranged on the fixed seat.

10. The automatic roll riveting apparatus of claim 9, wherein the abutment member is rotatably mounted to the holder; and/or the presence of a gas in the gas,

the abutting part is provided with a contact surface abutted to the abutting surface, and the contact surface is arranged in an arc surface mode.
