Description

Technical Field

[0001] The utility model relates to spot riveting of circular parts, in particular to a process device for spot riveting the side surfaces of circular parts. Background Art

[0002] Some circular aluminum parts are key components of some military products. The side spring hole baffles need to be spot riveted to prevent the spring from popping out. The riveted joints need to withstand the impact of bullets when they are fired. Because the spring holes are located at the arc of the circular side, the spot riveting consistency is required to be high. At the same time, the anchor point cannot protrude from the circumference, otherwise it will affect the installation of the parts. The existing spot riveting device has a complex structure, is not easy to operate, and has low measurement efficiency. Therefore, the art needs a process device with a simple structure that can be reused multiple times and can be used for inward extrusion riveting in the circumferential direction. Summary of the invention

[0003] The technical problem to be solved by the utility model is how to conveniently, accurately and efficiently spot-rivete the side of a circular part.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a process device for spot riveting the side of a circular part, comprising a base and a punch, the base being The base is in the shape of a circle, a center hole is arranged on the upper part of the base, a top cover is installed on the top of the punch, the punch is installed in the center hole, and a spring is sleeved on the punch located between the base and the top cover; a limit block is arranged on the lower part of the base, a positioning pin hole is arranged on the base next to the limit block, a positioning pin is embedded in the positioning pin hole, and the positioning pin and the limit block position the installed circular parts.

[0005] A limiting hole is arranged on the side of the center hole on the base, a positioning screw is arranged in the limiting hole, a limiting groove is arranged on the side wall of the punch, and after the punch is inserted into the center hole, the positioning screw goes deep into the limiting groove to limit the punch.

[0006] The utility model adopts a process device designed by the above technical solution for spot riveting the side of circular parts. The punch is limited in the base by a positioning screw so that it can only move up and down along the axis. The base is provided with positioning pins and positioning blocks according to the shape of the part. The punch is lifted to place the part on the base according to the positioning. The anchor point of the punch is opposite to the spring hole on the side of the part. The whole tool is placed in a lever press and pressed according to the set pressure value. After pressing, the tool is taken out. The punch automatically pops up under the action of the spring to facilitate the removal of the part. The spot-riveted parts are taken out and transferred to the next road for inspection. The utility model has a simple structure and is easy to clamp. The punch can be replaced at will after being damaged. It is simple to operate and can perform four anchor points in a circle at one time. The riveting is uniform, the riveting strength is good, the spot riveting consistency is good, the cost is low, and the efficiency is high. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following is a detailed description of a process device for spot riveting the side of a circular part according to the utility model in conjunction with the accompanying drawings.

[0023] The utility model is a process device for spot riveting the side of a circular part, see Figures 1 to 14 , including a base 1 and a punch 3, the base 1 is The punch 3 is shaped like a punch 3, a center hole 9 is provided on the upper part of the base 1, a limiting hole 8 is provided on the side of the center hole 9 on the base 1, and a positioning screw 4 is set in the limiting hole 8. A limiting groove 12 is provided on the side wall of the punch 3, a top cover 6 is provided on the top of the punch 3, the top cover 6 is screwed and installed in the punch 3, and the punch 3 is installed in the center hole 9. A spring 5 is set on the punch 3 located between the base 1 and the top cover 6. After the punch 3 is installed in the center hole 9, the positioning screw 4 penetrates into the limiting groove 12 to limit the punch 3, so that the punch 3 can move up and down freely and limit in the center hole 9. A limiting block 11 is provided at the lower part of the base 1, and a positioning pin hole 10 is provided on the base 1 next to the limiting block 11. A positioning pin 2 is embedded in the positioning pin hole 10, and the positioning pin 2 and the limiting block 11 position the installed circular part 7.

[0024] When the utility model is used, the baffle opening is downwardly installed in the spring hole of the circular part, the punch component is pulled up, the circular part with the baffle installed is put into place according to the positioning set on the tooling, the punch component is loosened so that its anchor point freely corresponds to the position of the spring hole of the circular part, the tooling with the installed parts is placed in a lever press, and is pressed according to a set pressure value. After pressing, the tooling is taken out, and the punch automatically pops up under the action of the spring to facilitate the removal of the parts.
